    Notes: Abstract Epstein-Barr virus (EBV) infection can induce uncontrolled lymphocyte B proliferation in immunosuppressed transplant patients. Monitoring circulating EBV-infected lymphocytes can help in identifying patients at risk of posttransplant lymphoproliferative disease (PTLD). Circulating EBV genome levels were determined in 54 liver transplant pediatric recipients. Ten patients had more than 500 EBV genome/105 peripheral blood lymphocytes (PBL) and exhibited clinical manifestations of EBV infection; three developed PTLD. To treat EBV infection, the level of immunosuppression was reduced and acute rejection developed in 4 patients. Three were treated with steroid and one had to be switched from cyclosporine to tacrolimus. Treatment of acute rejection was associated with increases in circulating EBV genome. None of the patients with less than 500 EBV genome/105 PBL developed PTLD or EBV infection. Monitoring of EBV DNA is useful in the management of EBV infection and PTLD following pediatric liver transplantation. EBV infection should be treated in ways which do not expose patients to the risk of rejection.

    Notes: Abstract  A new monoclonal antibody, Wue-1, which specifically recognizes normal and malignant plasma cells, is characterized. Biochemical studies showed that monoclonal antibodies (mAbs) recognize a protein of 94 kDa. Using triple-staining flow cytometry and double-labeling immunohistochemical techniques, two populations of plasma cells, i.e. lymphoplasmocytoid plasma cells located in the germinal center of lymphoid organs and reticular plasma cells at the paracortex or medullary cords of secondary lymphoid tissues, were distinguished. Wue-1 is expressed when B-cell markers become lost and secretory activity with plasma cell morphology appears. Cell surface markers were identified on normal plasma cells and compared with their malignant counterpart in vivo. Terminal plasma–cellular differentiation of malignant low- and high-grade B-cell lymphoma and anaplastic plasmacytoma, otherwise difficult to identify with conventional B-cell markers on tissue sections or fluorescence-activated cell sorter analyses, were detectable by Wue-1. In cell culture, Wue-1 enhanced the proliferation of myeloma cell lines but not normal plasma cells in a dose-dependent manner. Since Wue-1-induced proliferation was increased by interleukin (IL)-6, Wue-1 recognizes a so far unidentified antigen with functional properties. Therefore, Wue-1 represents a useful new tool for therapy and for the in vivo and in vitro studying of B-cell lymphomas and the mechanisms of B-cell differentiation.

    Notes: Abstract  Objective. To evaluate the bone mineral status of children being treated for X-linked hypophosphatemia, including potential differences between cortical bone in the radial diaphysis and combined cortical and trabecular bone in the lumbar spine. Design and patients. Forty-four bone mineral evaluations were performed in 11 children and adolescents with X-linked hypophosphatemia. Bone mineral density (BMD) of the lumbar spine and the radial diaphysis were measured by dual X-ray absorptiometry (DXA), second metacarpal cortical thickness was measured on hand radiographs, and these results were expressed as Z-scores (standard deviations from the mean). Results. For the 11 initial examinations, Z-scores (mean±SD) were: radial BMD, –2.73±1.15, lumbar BMD, +1.28±1.53; and cortical thickness, –2.21±0.95. Lumbar BMD Z-scores were significantly greater than those for radial BMD and cortical thickness. On follow-up examinations there was a mild increase in radial BMD and decrease in lumbar BMD. Although these changes were statistically significant, they were quite small and the discordance between radial and lumbar BMD was not corrected. Conclusions. Children and adolescents who are being treated for X-linked hypophosphatemia manifest a bone mineral disorder characterized by decreased BMD in the appendicular skeleton and increased BMD in the lumbar spine. Although current therapy is successful in its anti-rachitic effects, it does not correct this bone mineral disorder and additional therapeutic trials should be considered.

    Description / Table of Contents: Abstract Background: About 10% of all schoolchil- dren are suffering from migraine and 50% from tension-type headache. Headache of acute onset usually will be treated with analgesic substances like paracetamol, acetylsalicylic acid or ibuprofen, the first one being the reference drug for tension-type headache in childhood. In case of lacking improvement or side-effects there is demand for an alternative safe substance for the acute analgesic therapy. Methods: In a double-blind randomised investigation flupirtine and paracetamol were given in two consecutive attacks of episodic tension-type headache. 30 children, 6–12 years old, were included. Dosage was determined according to age and weight. The children documented the acute headache intensity and duration in a special diary. Results: Headache intensity was reduced during 2 h after intake in 89% of the 19 children treated. The reduction was 6,5 to 3,1 for flupirtine and 6,9 to 3,3/10 for paracetamol. There was no statistically significant difference between the two substances. Relevant side-effects could not be observed. Conclusion: Flupirtine has shown a convincing clinical effect treating acute episodic tension-type headache for children. The substance was well tolerated by the patients. In addition, flupirtine provides a high degree of safety.
    Notes: Zusammenfassung Hintergrund: Etwa 10% aller Schulkinder leiden nach neueren deutschen epidemiologischen Untersuchungen zumindest gelegentlich an Migräne und etwa 50% an Kopfschmerzen vom Spannungstyp. Häufig nehmen sie bei Spannungskopfschmerzen analgetische Monosubstanzen wie Paracetamol, Azetylsalizylsäure oder Ibuprofen ein. Bei nicht ausreichender Wirkung bzw. Unverträglichkeit besteht Bedarf nach weiteren Substanzen für die Akutanwendung. Methode: In einer doppelblindrandomisierten und gekreuzten Anordnung wurden Paracetamol bzw. das analgetisch und muskelrelaxierend wirksame Flupirtin 30 6- bis 12jährigen Kindern für 2 episodische Spannungskopfschmerzattacken angeboten. 10 Kinder benötigten nach dem Erstkontakt keine Medikation mehr, 1 Kind lehnte die Einnahme grundsätzlich ab. Ergebnisse: Die Kopfschmerzstärke verringerte sich laut Kopfschmerztagebuch innerhalb von 2 h nach der Einnahme auf einer numerischen Schmerzskala (0–10) von 6,5 auf 3,1 unter Flupirtin und von 6,9 auf 3,3 unter Paracetamol bei 89% der verbliebenen 19 Kinder. Statistisch signifikante Unterschiede zwischen beiden Substanzen bestanden nicht. Als Nebenwirkung trat 1-mal Erbrechen unter Paracetamol auf. Schlussfolgerung: Flupirtin hat sich in der Akutphase von episodischen Spannungskopfschmerzen beim Kind bewährt. Es verfügt über eine gute Verträglichkeit. Im Vergleich zu Paracetamol scheint v.a. bei akzidenteller Überdosierung eine größere Sicherheit zu bestehen.

    Description / Table of Contents: Abstract Background. The assessment and measurement of pain is essential in the implementation and control of pain relieving strategies. The measurement of pain in infants and children should be based on the consideration of age, cognitive level, psychological status, intercurrent diseases and the social context in order to register the child's individual situation and to avoid misinterpretation. Diagnosis. In the preverbal infant, behavioral and physiological cues have to be interpreted by the caregivers. For the assessment of pain in children of four and older who have at least a basic understanding of the pain concept self assessment methods (as rating scales, specific pain interviews, diaries and questionnaires) can be used. In any case the instruments used should be age appropriate. The instruments used for the different age groups are presented with comments on quality and clinical applicability.
    Notes: Zusammenfassung Hintergrund. Voraussetzung zur Durchführung und Kontrolle einer adäquaten und effektiven Schmerztherapie sind die Erfassung und Quantifizierung des Schmerzes in seinen verschiedenen Dimensionen. Bei der Diagnostik des Schmerzes im Kindesalter müssen Alter, kognitiver Entwicklungsstand, psychologischer Status, interkurrierende Erkrankungen und der soziale Kontext berücksichtigt werden, um das Kind in seiner individuellen Situation erfassen zu können und Fehleinschätzungen zu vermeiden. Schmerzdiagnostik im Kindesalter. Im präverbalen Alter werden die physiologischen und verhaltensbezogenen Schmerzäußerungen von Neugeborenen, Säuglingen und Kleinkindern durch eine Fremdbeurteilung erfasst. Bei Kindern ab etwa 4 Jahren, die über ein einfaches Verständnis von Schmerz verfügen, sind Verfahren der Selbsteinschätzung wie einfache Ratingskalen, spezifische Schmerzinterviews, Tagebücher und Fragebögen die primär einzusetzenden Instrumente. In jedem Fall sollten die Instrumente altersgerecht gestaltet sein. Für die verschiedenen Altersgruppen werden Instrumente der Schmerzerfassung mit qualitativen Hinweisen auf deren Güte und klinische Anwendbarkeit vorgestellt.

    Description / Table of Contents: Abstract Phenomenon pain. While pain is one of the main reasons for an unscheduled visit to the paediatrician, pain due to painful procedures is of major importance in scheduled visits. Actual pain therapy is illustrated in the treatment of burns. Incomplete analgesia may have an unfavourable impact on morbidity and mortality. The pain score does not correlate with the extent of the burned area, and is regularly underestimated. General anaesthesia or analgo-sedation are warranted during the care of the burned patient. Unsufficient analgesia. Consequence of insufficient analgesia during primary care is an increased need of analgesics, and an increased pain treatment failure rate during subsequent procedures. Pain is interfering with anxiety, sleep disturbancies and post-tramatic psychologic alterations. All those symptoms must be treated adequately. Acute illness and injections. This article covers pain from otitis media, pharyngitis, Guillain-Barré syndrome, purpura fulminans, Toxic Epidermal Nekrolysis, as well as the usage of local anaesthesia during injections, not to forget the application of non-pharmacologic methods for pain therapy and prophylaxis.
    Notes: Zusammenfassung Phänomen Schmerz. Das Phänomen “Schmerz” begleitet fast alltäglich den Kontakt zwischen Arzt und krankem Kind. Auf der einen Seite sind Schmerzen der häufigste Grund für eine ungeplante Kinderarztkonsultation, auf der anderen Seite sind bei geplanten Kinderarztbesuchen häufig schmerzhafte Prozeduren durchzuführen. Anhand der starken Schmerzen bei den im Kleinkindalter häufigen Verbrennungen werden schmerztherapeutische Prinzipien konkretisiert: Schmerztherapeutische Prinzipien. Unzureichende Analgesie kann Morbidität und Mortalität ungünstig beeinflussen. Das Schmerzmaß korreliert nicht mit der Ausdehnung der Verbrennung und wird vom Behandler regelmäßig unterschätzt. In vielen Fällen der Erstversorgung sind Allgemeinanästhesie oder Analgosedierung gerechtfertigt, ähnliches gilt für den Verbandwechsel. Ungenügende Analgesie bei der Erstversorgung führt zu erhöhtem Analgetikaverbrauch und schmerztherapeutischen Misserfolgen bei Folgeeingriffen. Wechselwirkungen zwischen Schmerzen und anderen Symptomen wie Angst, Schlafstörungen oder postraumatischen psychischen Veränderungen sind zu beachten und adäquat zu therapieren. Akute Erkrankungen + Injektionen. Weiter wird auf Schmerzen bei Otitis media, Pharyngitis, Guillain-Barré-Syndrom, Purpura Fulminans und Toxischer Epidermaler Nekrolyse sowie den Einsatz von Lokalanästhetika bei Injektionen eingegangen. Schließlich haben auch nicht pharmakologische Methoden ihren Platz in Schmerztherapie und Prophylaxe.

    Description / Table of Contents: Abstract Treatment of pain. Undertreatment of postoperative pain in children is a problem in clinical practice. This is due to a lack of both knowledge about age-specific aspects of physiology and pharmacology, and routine pain assessment. For example, the fear of side-effects prevents the adequate usage of opioids. It is of major importance to select a route of drug administration where the child feels comfortable with (avoid intramuscular injections). Non-opioid analgesics. Non-opioid analgesics are recommended for basic pain treatment after minor surgical procedures. Instead of using the whole multitude of drugs available, the doctor should stick to those drugs he is familiar with (acetaminophen, ibuprofen, diclofenac, dipyrone). Opioids. Opioid usage requires individual dose titration and careful monitoring of side-effects (respiratory monitoring, sedation score). The strong opioids piritramide and morphine may advantageously be administered as either continuous, or patient-controlled iv- infusion (PCA). Forms of therapy. In addition to infiltration anesthesia, intraoperatively applied nerve blocks provide excellent pain relief. Epidural analgesia with local anesthetics and/or opioids via a thoracic or lumbar epidural catheter is a therapeutic option after thoracic or abdominal surgery, or after extensive orthopedic or urological interventions. Adjuvant analgesics and nonpharmacologic interventions, i. e. transcutaneous electrical nerve stimulation (TENS), are primarily indicated in patients suffering from neuropathic pain. Conclusion. The establishment of pain services and the comprehensive education of both the nursing and the medical staff should help to improve postoperative pediatric pain therapy.
    Notes: Zusammenfassung Schmerztherapie bei Kindern. Postoperative Schmerzen bei Kindern werden häufig wegen mangelnder physiologischer und pharmakologischer Kenntnisse und des Fehlens einer regelmäßigen standardisierten Schmerzmessung noch immer unzureichend behandelt. Die Angst vor Nebenwirkungen verhindert eine adäquate Opioidtherapie. Bei der Verwendung von Analgetika ist auf eine kindgerechte Applikationsweise (keine i.-m.-Injektionen!) zu achten. Nichtopioidhaltige Analgetika. Nichtopioidhaltige Analgetika (Parazetamol, Ibuprofen, Diclofenac, Metamizol) sind zur Basisschmerztherapie bei kleineren schmerzhaften Eingriffen geeignet. Opioide. Opioide müssen nach Wirkung titriert werden; Nebenwirkungen können nur bei sorgfältigem Monitoring von Atmung und Sedierungsgrad frühzeitig erkannt werden. Opioide (Tramadol, Piritramid, Morphin) können entweder kontinuierlich i. v. oder mittels PCA-Pumpe verabreicht werden. Therapieformen. Neben der Oberflächenanästhesie sind intraoperativ angelegte Nervenblockaden effektive therapeutische Möglichkeiten. Eine lumbale und thorakale Periduralanästhesie mittels Lokalanästhetika und/oder Opioiden bietet sich bei thorakoabdominalen Eingriffen an. Koanalgetika werden vornehmlich bei Nervenschmerzen verwendet und richten sich gegen die schmerzverursachende Pathophysiologie. Optimierung der Schmerztherapie. Die postoperative Schmerztherapie bei Kindern kann durch Einrichtung eines Akutschmerzdiensts und kontinuierliche Weiterbildung von Pflegepersonal und Ärzten optimiert werden.

    Description / Table of Contents: Abstract Background. In paediatrics, numerous diseases present with the leading symptome of muscular, articular, or bone-related pain. The pain as such is seldom diagnostic with regard to pain etiology. Regularly, the significance of inflammatory as well as non-inflammatory pain is underestimated. Classification of musculosceletal diseases. We present 4 case reports, illustrating the classification of musculosceletal diseases into 4 main groups, being the basis for the modelling of disease, and pain treatment. Therapy. Pain therapy is either symptomatic or based on specific pathophysiology. Pain therapy consists of the moduls analgesics, antiphlogistics, physiotherapy, psychosocial support, and complementary therapies. We give advice on differential therapy. A transparent team-oriented concept comprising physicians, physiotherapists, ergotherapists, psychologists, and social workers is the basis for any successful long-term therapy. Regular outpatient visits in consent with the family doctor are mandatory as are education and treatment periods on ward. We encourage our patients to join formal self-supportive patient groups.
    Notes: Zusammenfassung Hintergrund. Eine Vielfalt an Grunderkrankungen präsentiert sich im Kindesalter mit Schmerzen des Bewegungsapparats als Leit- oder Begleitsymptom. Die Schmerzäußerung allein lässt nur selten eine sichere ätiologische Differenzierung zu. Entzündliche sowie nichtentzündliche muskuloskelettale Beschwerden werden regelmäßig in ihrer Bedeutung unterschätzt. Hauptgruppen muskuloskelettaler Erkrankungen. Anhand von Fallbeispielen unterschiedlicher Schmerzcharakteristik und Begleitsymptomatik stellen wir 4 Hauptgruppen muskuloskelettaler Erkrankungen vor. Diese Einteilung ist Grundlage der Entwicklung von Krankheits- und Behandlungsmodellen des Schmerzes. Therapie. Die Schmerztherapie ist teils symptomatisch, teils pathophysiologisch begründet, und besteht aus den Therapiemodulen Analgetika, antiinflammatorische Therapie, Krankengymnastik, psychosoziale Begleitung und komplementäre Therapien. Hinweise für die Differenzialtherapie werden angegeben. Ein für alle Beteiligten transparentes teamorientiertes Konzept mit der Einbindung von Ärzten, Krankengymnasten, Ergotherapeuten, Psychologen und Sozialarbeitern hat sich als Grundlage einer erfolgreichen Langzeitbetreuung erwiesen. Wichtig sind regelmäßige ambulante Kontakte in Absprache mit dem Hausarzt, ggf. Schulungen und stationäre Aufenthalte. Die Zusammenarbeit mit Selbsthilfegruppen hat sich innerhalb eines solchen Therapieplans erfolgreich etabliert.

    Notes: Abstract  We carried out a retrospective survey on 152 children and adolescents with nephrocalcinosis (NC) in 22 German centers of pediatric nephrology. Etiology, clinical manifestations, growth and development, sonographic appearance of NC and renal function were analyzed. The median age at the time of diagnosis was 3.3 (range 0.1–21) years and the median duration of follow-up was 4.1 years. In 34% of children NC was associated with idiopathic hypercalciuria (IHC) and in 32% with various hereditary tubular disorders. In 9% NC was observed subsequent to prophylactic bolus administration of vitamin D in infancy. A positive family history was found in 36%. Clinical manifestations were mainly failure to thrive during the 1st year of life (46%), psychomotor/mental retardation (28%) and urinary tract infection (34%). In 14% nephrolithiasis was associated. During the follow-up the proportion of patients with the most severe degree of NC (stages 2b or 3) increased from 40% to 55% and that of hypercalciuria decreased from 79% to 52%. Body height was 〈2 standard deviation scores (SDS) of normal in 41% at the time of diagnosis and in 32% at the last observation; the increase in relative height was significant only for IHC. Glomerular filtration rate (GFR) and urinary concentration capacity changed only slightly with time. At the last investigation GFR was 〈50 ml/min/1.73 m2 in 6% and concentration capacity 〈800 mosmol/kg in 48% of patients. The degree of NC was negatively correlated with GFR and concentration capacity.

    Notes: Abstract  A child with chronic relapsing thrombotic thrombocytopenic purpura (TTP/HUS) had recurrent thrombocytopenia, microangiopathic hemolytic anemia with fragmented erythrocytes, microthrombi in the lung vessels, and renal dysfunction. Assay of von Willebrand factor (vWF)-cleaving protease showed a complete protease deficiency in the patient and subnormal activities in the mother and in two asymptomatic siblings. No inhibitor of vWF-cleaving protease was detected in the patient’s plasma. Periodic transfusions of fresh-frozen plasma prevented further acute episodes of TTP/HUS. Specific diagnosis of the constitutional deficiency of vWF-cleaving protease helps to provide successful prophylactic therapy.

    Notes: Abstract  The calcium channel blockers (CCBs) are a diverse group of antihypertensive medications with variable pharmacokinetics and clinical effects. Although CCBs have been widely applied to the treatment of hypertensive children, data regarding the pharmacokinetics, efficacy and safety of these agents in children are extremely limited. In this review we briefly summarize the mechanism of action of CCBs and then summarize pertinent pharmacokinetic information on each of the CCBs commonly used in children, including amlodipine, diltiazem, felodipine, isradipine, intravenous nicardipine, nifedipine and verapamil. Clinically important drug interactions and adverse effects are discussed, as well as the potential role of CCBs in renal protection. Available pediatric efficacy and safety data are summarized, and recommendations made regarding the rational use of CCBs in the management of pediatric hypertension.

    Notes: Abstract  X-linked hypophosphatemia (XLH) is characterized clinically by rickets, hypophosphatemia and hyperphosphaturia. Conventional treatment of XLH with oral phosphate and vitamin D is associated with hypercalcuria and nephrocalcinosis. Recently, intravenous and oral dipyridamole has been reported to decrease fractional excretion of phosphate in adults with idiopathic hyperphosphaturia. Our objective was to determine whether oral dipyridamole therapy reduces urinary phosphate excretion and increases serum phosphate concentration in children with XLH. A prospective study was performed in six children with XLH. The average age of the patients at the start of the study was 12.5±1.0 years. The effects of 12 weeks of oral dipyridamole therapy, at 4.4±0.4 mg/kg body weight per day, on serum phosphorous, parathyroid hormone (PTH), 1,25 (OH)2 vitamin D, osteocalcin, tubular maximum for phosphate reabsorption (TmP/GFR), urinary calcium excretion, and cyclic adenosine 3’,5’-monophosphate (cAMP) excretion, were compared to baseline levels. Our results show that there was no change in serum phosphorous concentration or TmP/GFR after 12 weeks of dipyridamole therapy. Dipyridamole therapy also had no effect on serum PTH, serum 1,25 (OH)2 vitamin D, alkaline phosphatase, osteocalcin levels, urinary calcium or cAMP excretion. We therefore concluded that in children with XLH, a 12-week course of dipyridamole had no effect on serum phosphorous or its urinary excretion. Dipyridamole therapy is unlikely to improve the bone disease in children with XLH.

    Notes: Abstract  Idiopathic acute renal failure (IARF) is an uncommon but severe complication in children with relapsing nephrotic syndrome and may require long-term dialytic support until recovery of renal function takes place. Due to limited understanding of the pathophysiology of IARF, specific guidelines for its prevention and therapy have not been developed. Among triggering factors, peritonitis was present in half of all pediatric patients with this complication described in the English literature over the past 15 years. We report an additional nephrotic child who developed IARF following spontaneous bacterial peritonitis. The renal biopsy showed tubular epithelial changes consistent with acute tubular necrosis. A discussion of related literature and possible pathogenesis of this association is presented.

    Notes: Abstract  Acute CT/MRI findings were examined in a prospective, longitudinal study of 60 children 0–6 years of age hospitalized for moderate to severe traumatic brain injury (TBI). TBI was categorized as either inflicted (n=31) or noninflicted (n=29). Glasgow Coma Scale scores and perinatal history were comparable in both groups. Acute CT/MRI studies were visually inspected by a radiologist blind to group membership. Compared with the noninflicted TBI group, the inflicted TBI group had significantly elevated rates of subdural interhemispheric and convexity hemorrhages as well as signs of pre-existing brain abnormality, including cerebral atrophy, subdural hygroma, and ex vacuo ventriculomegaly. Intraparenchymal hemorrhage, shear injury, and skull fractures were more frequent after noninflicted TBI. Subarachnoid hemorrhage and infarct/edema occurred with comparable frequency in both groups. Characteristic acute neuroimaging findings of inflicted TBI included multiple extraaxial hemorrhages in addition to the mild atrophy, subdural hygromas, and ventriculomegaly that suggest prior brain abnormality.

    Notes: Abstract  The objective of this study was to determine the main clinical, neurophysiological and angiographic findings in brain death (BD) in children seen at the Instituto Nacional de Pediatría, a third-level facility in Mexico City, between 1991 and 1996. The following variables were retrospectively analyzed: sex, age, etiology, associated morbidity, duration of stay in hospital, and the results of two of three confirmatory studies (electroencephalogram, evoked potentials, radioisotopic angiography). In all, 125 patients were studied [78 male; median age 2 years (range: 18 days to 17 years)]. The most frequent etiology was infection (34%); 57% of the children developed associated morbidity. In 111 of 122 patients electrocerebral silence was observed; 100 of 107 had brain stem and somatosensory evoked potentials affording conclusive evidence of BD; and 83 of 90 patients had a positive radioisotopic angiography indicating BD. In 76 patients all three confirmatory studies were performed: for 15 there was at least one false-negative test result. Our age cohort showed a predominance of children less than 2 years old. BD etiologies in developing countries differ from those reported in developed countries.

    Notes: Abstract  CT scanning is the current first imaging technique to be used after head injury, in those settings where a CT scan is available. The first scan is usually done without contrast enhancement. The value of CT is the demonstration of scalp, bone, extra-axial hematomas and parenchymal injury. It is rapid and easily done in the presence of the multiple monitors that many trauma patients have in place. It can be used to demonstrate the bony anatomy of the spine and is good for evaluation of abdominal and chest trauma also. MRI is more sensitive for all post-traumatic lesions other than skull fracture and subarachnoid hemorrhage, and can demonstrate parenchymal spinal cord injury. The cons are a longer scanning time, interference of the imaging by certain ICP monitors and problems with the positions of the monitoring equipment and ventilators outside the MRI magnetic field. MRI will be used increasingly to study early head injury because of its ability to measure cerebral blood flow, cerebral blood volume and the location and extent of cerebral edema. If the CT does not demonstrate pathology adequate to account for the clinical state, MRI is warranted. Follow up is best done with MRI as it is more sensitive to parenchymal change than is CT.

    Description / Table of Contents: Summary Cicatricial pemphigoid (CP) is a rare autoimmune disease characterized by subepidermal blistering and progressive cicatrization affecting the skin and mucosa. Ocular involvement occurs in approximately 70% of the patients. Methods: The course of the disease, complications and putative risk factors in patients with ocular cicatricial pemphigoid (OCP) treated at the Departments of Ophthalmology and Dermatology were analyzed retrospectively from 1986 to 1998. Results: Eighteen of 28 patients (64%) with CP demonstrated ocular involvement. The mean age of patients with OCP was 73 years; 61% were female. At the time of referral to our hospital, all patients had reached advanced stage III (83%) or IV (17%) of OCP. In 38% of patients vision was already reduced to 〈20/200 at first presentation. Twenty-eight percent of patients additionally suffered from glaucoma. Two patients exhibited life-threatening extraocular manifestations of CP (larynx stricture, esophagus stricture). Conjunctival or mucosal biopsies were performed in 15 patients with OCP and showed typical immunodeposits at the basement membrane zone in 12/15 patients. Therapy with dapsone (12 patients), oral steroids (11 patients), azathioprine (5 patients), cyclophosphamide (4 patients), colchicine (2 patients) and methotrexate (1 patient) was used concomitantly or consecutively. Complications of OCP including entropion, recurrent epithelial erosions, corneal ulcers, keratitis, and corneal perforations required multiple surgical interventions such as entropion surgery (8 patients), tarsorrhaphy (3 patients), mucous membrane grafting (1 patient), amniotic membrane transplantation (1 patient), tectonic keratoplasty (1 patient), keratoprosthesis (1 patient) and enucleation (1 patient). Despite control of the inflammatory process, further visual loss occurred in 53% of eyes. Reading visual acuity could only be maintained in 35% of eyes. Discussion: Early diagnosis and therapy can prevent ocular complications of OCP. This study indicates that advanced stages of the disease often result in irreversible visual loss despite institution of immunosuppressive therapy. Whether or not the high association of OCP with glaucoma and/or anti-glaucomatous treatment in our patients represents part of the underlying disease process or plays a role in the pathogenesis of OCP must still be clarified.
    Notes: Zusammenfassung Das vernarbende Pemphigoid (cicatricial pemphigoid, CP) ist eine seltene, mit subepidermaler Blasenbildung und Vernarbung einhergehende Autoimmunerkrankung, die sich an Haut und Schleimhaut manifestiert. Eine Augenbeteiligung liegt bei etwa 70% der Patienten vor. Methode: Retrospektiv wurden Krankheitsverlauf, klinische Komplikationen und mögliche Risikofaktoren von Patienten der Augen- und Hautklinik mit vernarbendem Pemphigoid von 1986–1998 untersucht. Ergebnisse: 18/28 Patienten (64%) mit CP hatten eine okuläre Beteiligung. Das Durchschnittsalter der Patienten mit okulärem vernarbendem Pemphigoid betrug 73 Jahre, 61% der Patienten waren weiblich. Bereits bei Erstvorstellung in unserer Klinik bestand bei allen Patienten ein Krankheitsstadium III (83%) oder IV (17%), mit einem Visus 〈0.1 in 38% der Augen. Bei 28% der Patienten wurde zusätzlich ein Glaukom diagnostiziert. Zwei Patienten zeigten eine lebensgefährliche extraokuläre Schleimhautbeteiligung (Larynx- bzw. Ösophagusstriktur). Bei 15 Patienten mit okulärem vernarbendem Pemphigoid wurde eine Bindehaut- bzw. Schleimhautbiopsie aus dem Mund oder Nasen-Rachen-Raum durchgeführt, welche die Verdachtsdiagnose bei 12/15 Patienten immunhistologisch sicherte. Eine Therapie mit Dapson (12 Patienten), oraler Kortikosteroidgabe (11 Patienten), Azathioprin (5 Patienten), Cyclophosphamid (4 Patienten), Colchizin (2 Patienten) und Methotrexat (1 Patient) wurde in Folge oder Kombination eingesetzt. Komplikationen wie Lidfehlstellungen, rezidivierende Epitheldefekte, Hornhautulzera, Keratitiden und Hornhaut-Perforationen erforderten multiple operative Eingriffe wie Entropium-Operation (8 Patienten), Tarsorrhaphie (3 Patienten), Kryoepilation (2 Patienten), Mundschleimhaut-Transplantat (1 Patient), Amniontransplantat (1 Patient), tektonische Keratoplastik (1 Patient), Keratoprothese (1 Patient) und Enukleation (1 Patient). Trotz befriedigender Kontrolle des okulären vernarbenden Pemphigoids kam es bei 53% der Augen zum weiteren Visusabfall. Ein Lesevisus konnte nur in 35% der Augen erhalten werden. Schlußfolgerung: Wahrscheinlich kann die Früherkennung und rechtzeitige Behandlung des okulären vernarbenden Pemphigoids okuläre Komplikationen verhindern. Diese Studie zeigt, daß trotz immunsuppressiver Therapie in Spätstadien häufig ein irreversibler Visusverlust resultiert. Es bleibt zu untersuchen, ob die auffällig hohe Assoziation von okulärem vernarbendem Pemphigoid zu Glaukom bzw. antiglaukomatöser Therapie in unserem Patientenkollektiv als Folge der Grunderkrankung oder als pathogenetischer Faktor zu werten ist.

    Description / Table of Contents: Abstract We report on the ventilation in prone position in a 5-year-old traumatized child with severe thoracic and abdominal injuries (lung contusion, rib fractures, rupture of liver and spleen). Under continuous analgosedation, the young patient was ventilated in prone position for 6 h, since acute lung injury and atelectasis persisted despite various therapeutic measures (artifical ventilation in the pressure controlled mode, fiberoptic bronchoscopy, reexpansion maneuver). After initiation of the prone position, we observed a rapid increase i narterial oxygenation, which persisted in the following period. The hemodynamic situation remained stable. The complete disappearance of atelectasis was demonstrated radiologically after supine repositioning. After cessation of analgosedation, the extubation was performed 2 days later. Furthermore, we found no side effects of the prone position on the injured abdomen, and the liver function improved rapidly. Although there is a lack of experience with ventilation in prone position in pediatric intensive care, our report might be a recommendation for the indication of this technique in children.
    Notes: Zusammenfassung In dieser Kasuistik wird über die erfolgreiche Anwendung der Beatmung in Bauchlage bei einem 5-jährigen Mädchen berichtet, welches von einem Pkw überrollt worden war und sich Thorax- und Abdominalverletzungen (Rippenserienfraktur, Lungenkontusion, Leber- und Milzeinrisse) zugezogen hatte. Wegen des akuten Lungenversagens mit persistierenden Atelektasen, die durch wiederholte fiberoptische Bronchiallavagen und durch Reexpansionsmanöver nicht zu beheben waren, wurde der Entschluss zur 6-stündigen Lagerung auf den Bauch gefasst, obwohl über den Effekt dieser Lagerungsmaßnahme bei traumatisierten Kindern wenig bekannt ist und zu möglichen negativen Auswirkungen auf das schwerverletzte Abdomen eine Informationen vorliegen. Die Beatmung in Bauchlage führte zur raschen Verbesserung des pulmonalen Gesaustausches, die hämodynamische Situation wurde nicht beeinflusst. Die radiologische Kontrolle nach Rücklagerung zeigte eine vollständigen Rückgang der Atelektasen; die kleine Patientin konnte bald darauf extubiert werden. Weder laborchemisch noch klinisch wurde ein schädigender Einfluss auf das verletzte Abdomen gefunden. Die Beatmung in Bauchlage hat sich als Routineverfahren bei der Behandlung des Lungenversagens des Erwachsenen etabliert; nach der hier beschriebenen Erfahrung ist diese Maßnahme auch bei traumatisierten Kindern in Betracht zu ziehen, insbesondere wenn andere Maßnahmen nicht ausreichend sind.

    Description / Table of Contents: Abstract Background and objective. This study compares the results of the outpatient-based program of the Cochlear Implant Center Ruhr with inpatient-based rehabilitation, which is almost exclusively performed in Germany. Patients/methods. The Department of Otorhinolaryngology at the University of Essen in Germany provided 52 patients with either 22- or 24-channel Nucleus cochlear implants from March 1996 to July 1999. Almost all patients (n=49) were rehabilitated on an outpatient basis, which is the standard in many cochlear implant centers outside Germany. Results. The longest follow-up period at the University of Essen Department of Otorhinolaryngology was 36 months. Minor complications occurred in 10% of the patients. After 24 months, the first three implanted patients were able to discriminate 100% of numbers and over 60% of syllables in the Freiburg speech discrimination test. The patients who developed an understanding of open speech were able to discriminate 31 words per minute with cochlear implant and without lipreading after 24 months. Children were seen to double their Schmid-Giovannini scores at 6 months postimplantation. Conclusions. The Essen outpatient-based cochlear implant program demonstrates results in speech development and speech understanding equal to those of centers providing inpatient rehabilitation. A special advantage is continuous rehabilitation with professionals known to the child for several years. In children especially, exhaustive commuting reduces school attendance and is a burden on the accompanying guardians. As an inpatient, however, the child is torn from his familiar environment. Parents with several children have particular difficulties in accompanying their child and indeed this may not always be possible.
    Notes: Zusammenfassung Hintergrund und Fragestellung. In dieser Arbeit werden die Ergebnisse der ambulanten Rehabilitation nach Cochlear-Implant-Versorgung mit denen der stationären Rehabilitation verglichen, die bisher in Deutschland fast ausschließlich durchgeführt wird. Von März 1996 bis Juli 1999 wurden an der Universitäts-Hals-Nasen-Ohren-Klinik Essen 52 taube oder an Taubheit grenzende Patienten mit einem 22-kanaligen bzw. 24-kanaligen Nucleuscochlear-Implant versorgt. Fast alle Patienten (n=49) konnten wohnortnah ambulant rehabilitiert werden, wie dies dem internationalen Standard entspricht. Ergebnisse. Der längste bisherige Nachbeobachtungszeitraum an der Universitäts-Hals-Nasen-Ohren-Klinik Essen sind 36 Monate. Nach 2 Jahren wurden von den 3 am längsten nachbeobachteten Patienten 100% der Zahlen und über 60% der Einsilber im Freiburger Sprachtest verstanden. Im “speech tracking” erreichten Patienten mit CI und ohne Lippenabsehen nach 24 Monaten 31 Wörter/min. Die Kinder zeigten 6 Monate nach Implantation eine Verdopplung des Scores im Test nach Schmid-Giovannini. Schlussfolgerungen. Das Essener Modell zeigt, dass eine ambulante Rehabilitation nach CI zu vergleichbaren Ergebnissen in der Sprachentwicklung und im Sprachverstehen führt, wie sie von anderen Zentren vorgelegt wurden, in denen fast ausschließlich stationär rehabilitiert wird. Besonders bei Kindern bedeuten lange Anfahrtswege mit einwöchigem stätionärem Aufenthalt Schulausfälle und eine Belastung für die begleitenden Eltern und Familienangehörigen zu Hause, sowie erhebliche Fahrtkosten. Stationäre Aufenthalte zur Rehabilitation reißen zudem das Kind aus seiner gewohnten Umgebung und sind für Eltern mit mehreren Kindern oft unmöglich.

    Description / Table of Contents: Abstract The results of international investigations on connatally acquired hearing loss are compared with the data of the German Registry on Childhood Hearing Loss (4058 cases). The connatal hearing disorders have shown a notable change in the last years regarding to aetiology and prevalence. In contrast to countries of the third world in developed nations the prevalence of permanent childhood hearing loss has been reduced down to 1 in 1.000 births. The results let assume a prevalence of approximately 1:1.200 births in Germany. For instance the number of rubella embryopathia decreased effectively. In contrast CMV infections and alcohol fetopathia are playing an increasing role. In the patients of the German Registry on Childhood Hearing Loss the percentage of certainly progressive hearing loss is 10.3 within the 4058 children with permanent hearing impairment. Diagnostic procedures first of all for the early diagnosis of CMV but also of toxoplasmosis are considerable because these infections may result in treatable hearing loss. Also consequent hearing tests are demanded in children with alcohol fetopathia.
    Notes: Zusammenfassung Im vorliegenden Beitrag werden die Daten internationaler Studien zu angeborenen erworbenen Hörstörungen mit den Ergebnissen aus 4058 Fällen im Deutschen Zentralregister für kindliche Hörstörungen (DZH) verglichen und ausgewertet. Die angeborenen Erkrankungen des Hörvermögens haben innerhalb der letzten Jahre bezüglich Ätiologie und Prävalenz einen deutlichen Wandel erlebt. Im Gegensatz zu Ländern der 3. Welt ist die Prävalenz permanenter kindlicher Hörstörungen in den westlichen Industrienationen auf ca. 1:1.000 gesunken. In Deutschland liegt die Prävalenz nach ersten Ergebnissen des DZH bei ca. 1,2:1.000. So ist beispielsweise der Anteil der Rötelnembryopathien stark zurückgegangen. Dagegen spielen heute die Zytomegalievirus-(CMV)-Infektion und die Alkoholfetopathie eine größere Rolle. Im Patientenkollektiv des DZH mit 4058 permanent hörgestörten Kindern beträgt der Anteil gesichert progredienter Verläufe 10,3%. Diagnostische Verfahren, vor allem zur Früherkennung von CMV und Toxoplasmose, gewinnen zunehmend an Bedeutung. Ebenso ist eine konsequente Hördiagnostik auch bei Kindern mit Alkoholfetopathie zu fordern.

    Description / Table of Contents: Abstract The case of a 60-year-old female patient with a supraglottic larynx carcinoma (T3N2CM0) and bilateral enlargement of the laryngeal sacculus is presented. On one side, the sacculus opened atypically into the left vestibular fold. The sacculus is a physiologic part of the roof of Morgagni's ventricle, the size of which can vary greatly. These canal-like structures can be the point of origin of cysts, laryngoceles, mucoceles, and pyoceles. Laryngoceles are present in about 5% of larynx carcinomas; their cause is not precisely known. Frequently, a computer tomogram suggests the coincidence of larynx carcinoma and laryngoceles or a large laryngeal sacculus. In oral panendoscopy, these ventricular distensions are difficult to detect even using 70° rigid endoscopes. A planned supraglottic partial resection must take into account early tumor growth along the preformed canals in the preepiglottic space. In this patient, a laryngectomy was performed due to the bilateral involvement of the vocal process and the anterior commissure.
    Notes: Zusammenfassung Es wird der Fall einer 60-jährigen Patientin mit einem supraglottischen Larynxkarzinoms (T3 N2c M0) und beidseitiger Vergrößerung des Sacculus laryngis vorgestellt. Einseitig mündete der Sacculus untypisch auf der linken Taschenfalte. Der Sacculus laryngis ist eine physiologische Ausstülpung des Daches des Morgagni-Ventrikels, dessen Größe sehr variieren kann. Diese gangartigen Strukturen können Ausgangsort von Zysten, Laryngozelen, Mukozelen und von Pyozelen sein. In ca 5% von Larynxkarzinomen liegen Laryngozelen vor, wobei der disponierende Faktor nicht genau bekannt ist. Oftmals ist der Verdacht der Koinzidenz von Larynxkarzinom und Laryngozele oder großem Sacculus laryngis in der Computertomographie zu stellen. In der Panendoskopie sind diese Erweiterungen der Ventrikel auch mit starren Winkeloptiken schwer zu sehen. Bei geplanter supraglottischer Teilresektion muss man an ein frühes Tumorwachstum entlang der präformierten Gänge in den präepiglottischen Raum denken. Bei der Patientin wurde bei beidseitiger Beteiligung der Processus vocales und der vorderen Kommissur eine Laryngektomie durchgeführt.

    Description / Table of Contents: Summary Recombinant growth hormone (rGH) therapy in the treatment of children with short stature was introduced 10 years ago, and experience has shown that progress in implementing this mode of therapy depends increasingly on analyses of large pharmaco-epidemiological studies. These studies prove that the diagnosis of growth hormone deficiency, whatever the cause or pathogenetic form, is the most frequent indication for GH therapy. The remaining problems are timely and precise diagnosis, and the best possible and individual therapy aiming at the projected height and taking safety and costs into account. We are closer to solving these problems today than ever before. Apart from this, the use of GH in treating short stature in Turner syndrome and renal insufficiency has led to its acceptance as a suitable therapy for these patients. Height improvement in a number of other growth disorders is, in certain cases, also possible through GH therapy. In the light of current experience, GH therapy can thus be attempted on a rational basis in individual cases. This form of treatment clearly holds wider possibilities and its implementation is likely to go beyond short stature in the future.
    Notes: Zusammenfassung 10 Jahre nach der Einführung von rekombinantem Wachstumshormon (WH) in die Therapie kleinwüchsiger Kinder werden unsere Erfahrungen zunehmend auch durch Analyse umfangreicher pharmako-epidemiologischer Beobachtungen geprägt. Wachstumshormonmangel: Diese zeigen, daß der Wachstumshormonmangel in seinen unterschiedlichen Ursachen und pathogenetischen Erscheinungsformen nach wie vor die häufigste Indikation für WH darstellt. Die Probleme bestehen weiterhin in der rechtzeitigen und rationellen Diagnostik und in der Optimierung und Individualisierung der Therapie zum Erreichen der Wachstumsziele unter ökonomischen Gesichtspunkten und bei gleichzeitiger therapeutischer Sicherheit. Diese Probleme sind für den WH-Mangel heute lösbar. Weitere Indikationen: Ferner zeigt sich, daß auch der Kleinwuchs beim Ullrich-Turner-Syndrom und bei der Niereninsuffizienz, für welche WH zugelassen ist, erfolgreich behandelt werden kann. Bei einer Vielzahl anderer Wachstumsstörungen ist die Möglichkeit zur Größenverbesserung im Einzelfall gegeben. Vor dem Hintergrund heutiger Erfahrungen kann ein individueller Heilversuch so auf eine rationale Basis gestellt werden. Zukunftsperspektiven: In Zukunft wird das breite Wirkpotential von Wachstumshormon über die Indikation des Kleinwuchses hinaus ausgeschöpft werden.

    Description / Table of Contents: Summary Case report: A 16-month-old girl was admitted with a 6-month history of multiple redishblue plaques on the right abdomen. These proved to have increased in size and number daturing a 1.5-year follow-up. Histologically (including histochemistry and electron microscopy), these skin changes were classified as tufted angioma. Tufted angioma is a rare, often multiple benign tumor. Half of the tumors reported develop in children 5 years and younger. The exclusion of malignant tumors (leukemia, lymphoma, neuroblastoma) is important. A punch biopsy is not very traumatic. A subsequent histological examination is highly sensitive and specific. Therapy: There are a few active therapeutic options with rather severel side effects.
    Notes: Zusammenfassung Fallbericht: Bei einem Mädchen im Alter von 16 Monaten traten seit einem halben Jahr am rechten Abdomen multiple, disseminierte rötliche bis bläulich-bräunliche infiltrierte Plaques auf, die innerhalb des 1,5-jährigen Beobachtungszeitraums weiter an Größe und Anzahl zunahmen. Mittels konventioneller Histologie, Immunhistologie und Elektronenmikroskopie sicherten wird die Diagnose eines Tufted Angioma. Das Tufted Angioma ist ein sehr seltener, häufig multipel vorkommender Tumor gutartigen Charakters. Die Hälfte der berichteten Tumoren entwickelte sich innerhalb der ersten 5 Lebensjahre. Deshalb ist der differenzialdiagnostische Ausschluss eines malignen Geschehens (Leukämie, Lymphome, Neuroblastom) von außerordentlicher Bedeutung. Hierzu ist eine Stanzbiopsie ideal geeignet, da sie einfach durchführbar und nur gering traumatisch ist. Die nachfolgende Histologie hat eine hohe Sensitivität und Spezifität. Therapie: Die aktiven therapeutischen Möglichkeiten müssen eher als eingeschränkt und nebenwirkungsreich gewertet werden. Eine spontane Rückbildung ist möglich.

    Description / Table of Contents: Abstract Although hydrodistension of the bladder is generally considered standard therapy for interstitial cystitis, scientific data are largely lacking. With the mechanism of action unknown, prospective studies non-existent and the therapeutic effect at best very short-lived, hydrodistension cannot be regarded as a therapeutic standard concept with scientifically validated efficacy. The value of behavioral therapy and bladder training is equally unclear; success can only be anticipated in the very rare subset of patients without pain.
    Notes: Zusammenfassung Obwohl die Hydrodistension der Harnblase ein häufig angewendetes Konzept in der Behandlung der intestitiellen Zystitis (IC) darstellt, ist die wissenschaftliche Datenlage zur therapeutischen Blasendehnung spärlich. Bei ungeklärtem Wirkungsmechanismus, fehlenden prospektiven und kontrollierten Studien und bestenfalls kurzfristiger Effektivität kann die Hydrodistension nicht als therapeutisches Standardkonzept mit wissenschaftlich nachgewiesenem Behandlungserfolg angesehen werden und besitzt eher den Stellenwert eines Heilversuchs. Die Wertigkeit von Blasentraining oder ähnlichen Miktonsverhaltensmodifikationen bei der IC bleibt ebenfalls unklar, ein gewisser Effekt kann allenfalls für die vergleichsweise kleine Untergruppe von IC-Patienten ohne Schmerzkomponente erwartet werden.

    Description / Table of Contents: Abstract Although autoantibodies against factor VIII or factor IX are a rare phenomenon, they are associated with a high risk of bleeding and high mortality. The condition, termed ac- quired haemophilia, occurs equally in both sexes and is most frequent in higher age groups. Patients typically present with severe bleedings in muscles and skin. In contrast to patients with congenital haemophilia and inhibitors, joint bleedings are very rare. In approximately half of all cases an associated disease state can be identified as the cause of autoantibody formation. An immediate and comprehensive diagnosis is essential for a rapid initiation of therapy. Equally important are a careful diagnostic differentiation between congenital and acquired factor deficiencies and the exclusion of non-specific inhibitors, which increase the occurrence of thrombolic events. The inhibitor titre, quantified using the Bethesda assay, is an important criterion for selecting the appropriate therapy. A wide range of treatment options is now available for the management of bleedings in patients with acquired haemophilia, namely porcine factor VIII, recombinant factor VIIa, prothrombin complex concentrates, and immunoadsorptions. In addition, immunosuppressive therapies are used to achieve permanent reduction or elimination of inhibitors.
    Notes: Zusammenfassung Autoantikörper gegen Faktor VIII oder Faktor IX sind ein zwar seltenes, aber mit hohem Blutungsrisiko und hoher Letalität verbundenes Phänomen. Diese als erworbene Hemmkörperhämophilie bezeichnete Erkrankung kommt bei beiden Geschlechtern gleich häufig vor und tritt gehäuft im hohen Lebensalter auf. Die Patienten fallen klinisch v. a. durch schwere Blutungen in Muskeln und Haut auf, wogegen Gelenkeinblutungen – im Gegensatz zur angeborenen Hämophilie mit Hemmkörpern – sehr selten auftreten. In etwa der Hälfte der Fälle kann eine assoziierte Grunderkrankung als Auslöser der Autoantikörperbildung identifiziert werden. Eine rasche und umfassende Diagnostik ist entscheidend für einen schnellen Therapiebeginn. Ebenso bedeutend ist eine sorgfältige differentialdiagnostische Abgrenzung gegen einen angeborenen oder erworbenen Faktorenmangel sowie der Ausschluß unspezifischer Inhibitoren, die vermehrt zu Thrombosen führen können. Wichtig für die Auswahl der geeigneten Therapieform ist der Inhibitortiter, gemessen im Bethesda-Assay. Für die Blutstillungstherapie steht heute mit porcinem Faktor VIII, rekombinantem Faktor VIIa, Prothrombinkomplexpräparaten und Immunadsorptionen ein breites Spektrum an Möglichkeiten zur Verfügung. Für eine dauerhafte Reduktion bzw. Elimination der Autoantikörper finden immunsuppressive Therapien Anwendung.

    Description / Table of Contents: Abstract Background: Postoperative nausea and vomiting (PONV) after tonsillectomy is a common problem in children. Tropisetron is a new 5HT3 receptor antagonist and is successfully used in paediatric patients receiving cancer therapy. The aim of the study was to assess efficacy and safety of a single intravenous dose of tropisetron for prevention of PONV in paediatric patients at risk for postoperative vomiting. Methods: In a randomised, double-blind, placebo-controlled trial, we studied 98 children aged 2–12 years undergoing tonsillectomy or adenotonsillectomy. Patients received placebo or tropisetron 0.1 mg (=0.1 ml)/kg body weight immediately after induction of anesthesia. A standard general anesthetic technique (Sevoflurane/N2O/O2 without neuromuscular blockers or opioids) was used. Perioperative vital signs, grade of sedation and episodes of postoperative nausea and vomiting were recorded. Results: No vomiting episodes occurred in 65.3% of the tropisetron treated patients compared to 34.7% of the placebo group (p=0.0024). Only 10.2% of the tropisetron treated patients vomited more than 3 times compared to 22.4% of the control patients (p=0.0004). The need for antiemetic rescue medication was significantly lower in the study group (10.4%) compared to 28.6% (p=0.025). No significant adverse effects of the study medication were shown. Conclusion: A single intravenous prophylactic dose of tropisetron effectively reduces the incidence of PONV during the first 24 postoperative hours after tonsillectomy and/or adenoidectomy. Because of the low incidence of adverse effects, the prophylactic use of tropisetron seems to be safe and justified in paediatric surgical patients at high risk for postoperative vomiting.
    Notes: Zusammenfassung Fragestellung: Erbrechen und Übelkeit nach Tonsillektomien bei Kindern sind ein häufiges Problem. Aufgrund der positiven Erfahrungen mit Tropisetron, einem neueren 5HT3 Rezeptor-Antagonisten bei Chemotherapien in der pädiatrischen Onkologie und mit anderen 5HT3 Rezeptor-Antagonisten in der Kinderchirurgie, prüften wir die Wirksamkeit und Sicherheit einer Einzeldosis Tropisetron zur Prävention von postoperativem Erbrechen bei chirurgischen Kindern mit erhöhtem Risiko für postoperatives Erbrechen. Methodik: Bei 98 Kindern im Alter von 2– 12 Jahren, die eine Tonsillektomie oder Adenotonsillektomie benötigten, führten wir eine randomisierte, doppelblinde, plazebokontrollierte Studie durch. Die Patienten erhielten Tropisetron oder Plazebo in einer Dosis von 0,1 mg (=0,1 ml)/kg KG i.v. unmittelbar nach der Narkoseeinleitung. Die Narkose erfolgte standardisiert mit Sevofluran/N2O/O2 ohne Einsatz von Opioiden und Muskelrelaxanzien. Vitalparameter, Sedationstiefe, das Auftreten von postoperativem Erbrechen und unerwünschte Wirkungen wurden aufgezeichnet. Ergebnisse: In der Tropisetrongruppe zeigten 65,3% der Kinder kein postoperatives Erbrechen, im Gegensatz zu nur 34,7% der Kinder in der Plazebogruppe (P=0,0024). Mehr als 3 Episoden von postoperativem Erbrechen zeigten nur 10,2% der Patienten in der Tropisetrongruppe im Vergleich zu 22,4% der Patienten der Kontrollgruppe (P=0,0004). Auch der Bedarf an antiemetischer Zusatzmedikation war in der Tropisetrongruppe mit 10,4% signifikant niedriger als in der Kontrollgruppe mit 28,6% (P=0,025). Bedeutsame Nebenwirkungen der Studienmedikation konnten nicht dokumentiert werden. Schlussfolgerungen: Eine prophylaktische intravenöse Einzelgabe von Tropisetron reduziert bei Kindern wirksam das Auftreten von postoperativem Erbrechen während der ersten 24 h nach einer Tonsillektomie oder Adenotonsillektomie. Die geringe Inzidenz von Nebenwirkungen rechtfertigt unserer Ansicht nach die prophylaktische Anwendung von Tropisetron bei Kindern nach Tonsillektomien.

    Description / Table of Contents: Abstract Impaired right ventricular (RV) function may be caused by pulmonary hypertension or myocardial ischemia. It is characterized by a dilation of the RV, which is followed by an increase of wall tension and O2-consumption and a decrease of RV ejection fraction (RV ‘dysfunction’). If a drop of arterial pressure occurs this my precipitate RV failure and shock (RV ‘insufficiency’). Diagnosis of RV failure and monitoring of RV function is difficult. Sometimes, even a severe impairment of RV function goes undetected or is misinterpreted. Patients in the operating room or on intensive care units seem to be especially prone to RV dysfunction and failure. Since a causative therapy often is not readily available, adequate symptomatic therapy is of utmost importance. Four basic principles have to be considered: 1) Optimizing preload: The failing RV requires adequate filling for preservation of stroke volume. On the other hand, overdistension of the RV may result in RV ischemia, thereby further deteriorating RV function Hence, volume loading is important, but requires continuous monitoring. 2) Maintenance of aortic pressure: Vasopressors are indicated if there is a critical drop of coronary perfusion pressure. Norepinephrine presently is the drug of choice for this purpose. 3) Reduction of RV afterload: Whereas intravenous vasodilators are limited in their efficacy in dilating pulmonary vessels due to systemic side effects, inhaled vasodilators result in selective pulmonary vasodilation and may improve RV function. 4) Increase of RV contractility: In RV failure and shock, norepinephrine and epinephrine are the drugs of choice. Inodilators are well suited for reducing pulmonary vascular resistance due to their positive inotropic and vasodilating effects. Since systemic vasodilation may occur, these drugs must only be used in hemodynamically stable patients.
    Notes: Zusammenfassung Eine Störung der Rechtsherzfunktion entsteht meist als Folge einer pulmonalen Hypertension, seltener bei primärer Myokardischämie. Sie ist gekennzeichnet durch eine Dilatation des rechten Ventrikels mit Anstieg von Wandspannung und Sauerstoffverbrauch bei reduzierter Ejektionsfraktion (“Dysfunktion”). Kommt es zum Abfall von arteriellem Druck und koronarem Perfusionsdruck, kann dies ein Rechtsherzversagen mit Schock auslösen (“Insuffizienz”). Diagnostik und Monitoring des rechten Ventrikels sind schwierig. Selbst eine schwere Beeinträchtigung der rechtsventrikulären Pumpfunktion bleibt daher häufig unbemerkt oder wird fehlgedeutet. Patienten in der perioperativen Phase und auf Intensivstationen scheinen besonders häufig von dem Krankheitsbild betroffen zu sein. Da eine kausale Therapie des akuten Rechtsherzversagens nur selten möglich ist, kommt der symptomatischen Therapie besondere Bedeutung zu. Sie stützt sich auf vier Prinzipien: 1) Optimierung der Vorlast: Der insuffiziente rechte Ventrikel benötigt zur Aufrechterhaltung seines Schlagvolumens ein gute Füllung. Andererseits kann eine Überdehnung des rechten Ventrikels eine Myokardischämie induzieren und seine Funktion weiter verschlechtern. Eine adäquate Volumentherapie ist daher essenziell, muss jedoch unter engmaschigem hämodynamischem Monitoring erfolgen. 2) Aufrechterhaltung des Aortendrucks: Bei kritischem Abfall des arteriellen Drucks ist die Gabe von Vasopressoren indiziert, um den rechtskoronaren Perfusionsdruck zu erhöhen. Noradrenalin gilt derzeit wegen seiner zusätzlich positiv inotropen Wirkung als Mittel der Wahl. 3) Verminderung der rechtsventrikulären Nachlast: Während sich intravenöse Vasodilatatoren wegen systemischer Nebenwirkungen nur bedingt zur Therapie der pulmonalen Hypertension eignen, dilatieren inhalierte Vasodilatatoren die pulmonale Strombahn selektiv und verbessern so die Pumpfunktion des rechten Ventrikels. 4) Steigerung der rechtsventrikulären Kontraktilität: Mittel der Wahl bei Dekompensation und Schock sind Noradrenalin und Adrenalin. Inodilatatoren weisen neben einer positiv inotropen auch eine pulmonal vasodilatierende Wirkung auf und eignen sich daher ebenfalls zur Therapie der rechtsventrikulären Dysfunktion. Sie sollten jedoch wegen der damit verbundenen systemischen Vasodilatation nur bei kreislaufstabilen Patienten eingesetzt werden.

    Description / Table of Contents: Abstract The main reason for posttraumatic secondary brain damage is cerebral hypoxia. Both, severity and duration of hypoxia are crucial in determining wether irreversible cerebral infarction will occur or not. For the clinical routine, the diagnosis of hypoxia is indirectly made by low CPP, low jugularvenous oxygen saturation (SjO2) or low tissue PO2. To minimize misleading false negative SjO2, the CT-Approach for the side of monitorig and calculation of arterial-jugularvenous lactate content for detection of anaerobic metabolism is recommended. Targeted treatment of hypoxia according to the underlying cause is mandatory. Primary goal is to increase cellular oxygen delivery by correction of low arterial oxygen content and elevation of regional CBF. Within the autoregulatory range decreasing CPP causes vasodilation and increasing CPP vasoconstriction with increasing or decreasing cerebral blood volume respectively. Initially elevation of the lower autoregulatory threshold often requires CPP 70 mmHg. Targeted treatment of intracranial hypertension must avoid decreasing CPP. In the early postrautmatic phase prevention of cerebral hypoxia relies on management of CBF by means of CPP and cerebral vascular resistance. Thereafter targeted treatment of intracranial hypertension caused by cerebral edema and hypervolemia are increasingly important.
    Notes: Zusammenfassung Hauptursache der sekundären Hirnschädigung ist die zerebrale Hypoxie. Abhängig von Schweregrad und Dauer entsteht eine irreversible Hirngewebsschädigung. Zur Diagnose der Hypoxie dient unter klinischen Bedingungen die kontinuierliche Messung des zerebralen Perfusionsdrucks (CPP) in Verbindung mit der zerebrovenösen O2-Sättigung (SjO2) oder der O2-Partialdruckmessung im Hirngewebe. Zur Minimierung von SjO2-Fehlinterpretationen sollte nach CT-Approach punktiert und ein anaerober Hirnstoffwechsel durch Bestimmung der arterio-jugularvenösen Laktatkonzentrationsdifferenz (avDL) ausgeschlossen werden. Die Therapie der zerebralen Hypoxie sollte kausal erfolgen. Normalisierung des arteriellen O2-Gehalts und Steigerung der Hirndurchblutung (CBF) haben Prioritöt. Bei intakter Autoregulation der CBF wird ein CPP-Abfall durch Vasodilatation mit Zunahme des zerebralen Blutvolumens und ein CPP-Anstieg durch Vasokonstriktion mit Abnahme des CBV kompensiert. Die häufige posttraumatische Rechtsverschiebung der unteren Autoregulationsschwelle erfordert in der Initialphase mit dem höchsten Hypoxierisiko CPP-Werte 70 mmHg. Die Therapie des ICP 〉 20 mmHg erfolgt CPP-orientiert. Eine ICP-Senkung zu Lasten des CPP ist zu vermeiden. Initial nach SHT hat die individuelle Optimierung der CBF durch Sicherstellung eines adäquaten CPP und zerebrovaskulären Gefäßwiderstandes (CVR) Priorität. Nachfolgend gewinnen durch SjO2 und avDL- oder Gewebe-PO2-Messung kontrollierte Maßnahmen zur Modulation von CVR und CBV sowie die Hirnödemtherapie zunehmend an Bedeutung.

    Notes: Abstract Renal venous thrombosis (RVT) occurs mainly in the neonatal period and bears a dismal prognosis for individual kidney function. There is no generally accepted therapeutic regimen as controlled clinical trials are lacking. Over the last few years, thrombolytic therapy has been successfully employed by single centres. The present study set out to gather up-to-date information on the incidence, therapy and outcome of neonatal RVT as part of a prospective nation wide survey on neonatal thrombosis in Germany to serve as a basis for therapeutic trials in the future. Between 1992 and 1994 the minimum incidence of symptomatic neonatal RVT in Germany was 2.2 per 100,000 live births (95% confidence interval 1.4–3.3). Out of 35 cases, RVT occurred in 15 premature babies (incidence 13 per 100,000 live births (95% confidence interval 5.9–24.8). Ten babies had associated caval occlusion. Therapy was supportive in 8, low dose heparin was used in 14, full heparinization in 9 and thrombolytic therapy in 4 children. On follow-up after a median time of 11.5 months, renal atrophy was present in 26 out of 39 affected kidneys. Conclusion Neonatal renal venous thrombosis still leads to irreversible kidney damage in the majority of cases. Because of the low incidence a multi-national multi-centre therapeutic trial over a long period has to be considered in order to determine the optimal therapeutic approach.

    Notes: Abstract It has recently been suggested that in adults with coeliac disease, faecal blood loss may play a role in the development of iron deficiency. A group of 45 children diagnosed with coeliac disease during 1996 and 1997 were therefore prospectively evaluated for the presence of gluten in their diet, iron deficiency anaemia, and faecal occult blood. Sixty children admitted for elective surgery or asthma served as controls. Faecal occult blood was found in four iron deficient children on normal diet, of whom three were newly diagnosed. Occult blood loss disappeared in three of the four children when gluten was removed from their diet. Faecal occult blood was found in 26.7% of children on gluten-containing diet, but not in children on gluten-free diet (P=0.01), or in control children (P=0.001). Conclusion Our data suggest that the incidence of occult blood loss in coeliac disease occurs mainly in newly diagnosed cases and responds to a gluten-free diet. Occult blood testing may not be warranted in the absence of iron deficiency anaemia nor in children with iron deficiency anaemia who are on a gluten-free diet.

    Notes: Abstract Gentamicin is widely used in paediatric medicine and therapeutic monitoring is mandatory due to the narrow margin of safety. Saliva sampling may be of potential interest, especially in children in whom blood sampling is often difficult. Experience with once daily intravenous administration of aminoglycosides has grown in recent years. Gentamicin levels were measured in serum and saliva of 55 children treated with the drug (5 mg/kg per day), administered intravenously in three different regimens: thrice (n=19), twice (n=18), and once daily (n=18). No correlation was found between serum gentamicin concentrations and saliva levels when the drug was administered twice or thrice daily, however, there was good correlation when the drug was administered once daily (r 2=0.96, P 〈 0.0001). Conclusion In children with uncomplicated infections treated with once daily gentamicin, trough concentrations of the drug can be monitored in saliva.

    Notes: Abstract Objective: To investigate whether the antioxidative sedatives propofol and thiopental can improve recovery from acute paraquat toxicity in A549 cells and in mice.¶Design: Prospective, controlled, dose-response, in vitro study and prospective, controlled animal study. Setting: A university animal research laboratory.¶Subjects: Established human lung cultured cells and male SPF ICR mice. Interventions: Paraquat-treated (0.2 mM) A549 cells were incubated either with the antioxidative sedatives propofol (0–0.56 mM) or thiopental (0–2.0 mM), or the non-antioxidative sedatives diazepam (0–3.0 mM), midazolam (0–3.0 mM) and ketamine (0–9.0 mM), as well as the antioxidative drugs, trolox (0–2.0 mM), α-tocopherol (0–4.4 mM), antioxidative-processed food (AOB; 0–1.0 mg/ml), superoxide dismutase (SOD; 0 and 3,000 U/ml) and ulinastatin (0 and 50,000 U/ml), for 48 h. Paraquat-treated mice received i. v. injections of 10 mg/kg propofol, 5 mg/kg thiopental, 4.0 mg/kg trolox, 100 mg/kg α-tocopherol, 10 mg/kg AOB or 5,000 U/kg SOD, b. i. d. for 4 days (n = 10 each). Measurements and results: Post-administered propofol and thiopental, as well as the antioxidative drugs, trolox, α-tocopherol and AOB, improved A549 cell survival in vitro. The non-antioxidative sedatives SOD and ulinastatin were not protective. An i. p. injection of 50 mg/kg of paraquat resulted in a survival rate of 40 % in mice at day 6. Propofol, trolox, α-tocopherol and AOB significantly lowered the mortality rate (80 % survival), while thiopental did not.¶Conclusion: Post i. v. injection of propofol is protective against paraquat-induced damage. Propofol can be given during mechanical ventilatory support after paraquat poisoning.

    Notes: Abstract Erythropoietic protoporphyria (EPP, MIM 177000) is an inherited disorder caused by a partial deficiency of ferrochelatase (FECH) which catalyses the chelation of iron into protoporphyrin to form haem. The majority of EPP patients experience solely a painful photosensitivity whereas a small number of them develop liver complications due to the accumulation of excessive amount of protoporphyrin in the liver. EPP is considered to be an autosomal dominant disorder, however, with a low clinical penetrance. To date, a total of 65 different mutations have been identified in the FECH gene of EPP patients. Among the 89 EPP patients who carry a “null allele” mutation which results in the formation of a truncated protein, 18 of them developed EPP-related liver complications. None of the 16 missense mutations identified among 19 patients on the other hand, have been associated with liver disease (P = 0.038). The allelic constellation of an overt patient consists of a mutated FECH allele and a “low expressed” normal allele and that of an asymptomatic carrier, a combination of a mutated and a normally expressed FECH allele. The identification of the “low expressed” allele is facilitated by haplotype analysis using two single nucleotide polymorphisms, −251 A/G in the promoter region and IVS1−23C/T. At the current time when only partially effective therapies are available, the disclosures of both “null allele” and the “low expression” mechanisms will improve patient management. Conclusion While covering the important clinical aspect of erythropoietic protoporphyria, this article emphasises the latest achievements in the molecular genetics of the disorder.

    Notes: Abstract This double-blind, randomised and cross-over study was designed to compare the preventive effect against exercise-induced bronchoconstriction (EIB), defined as the percentage decrease in FEV1≥15% after 6 min of exercise, of 2 mg and 10 mg of sodium cromoglycate (SCG), administered through a metered dose inhaler via spacer, in asthmatic children. Each of the 30 subject (age 11.6 ± 3.2 years) was tested on five occasions. For inclusion, EIB in test1 was required. In tests 2 to 5, all subjects inhaled 2 mg or 10 mg of SCG 20 min and 120 min before exercise in a randomised order. In order to assess excretion of eosinophil protein X (EPX) accompanying EIB, urine samples were collected before and after exercise. The mean percentage fall in FEV1 (±SD) in test 1 was 26.8 ± 9.8%. Inhalation of 2 mg and 10 mg of SCG 20 min before exercise provided a significant preventive effect in 83% and 77% and inhalation 120 min before exercise provided a preventive effect in 63% and 70%, respectively (n=30). Variance analysis did not reveal a statistically different absolute fall in FEV1 after exercise when both doses (120 min before exercise) were compared (P=0.356). In an unselected subgroup of 12 children, urinary EPX increased after the challenge without SCG premedication (test 1) (mean change: +48.7 μg/mmol creatinine, P=0.034), whereas no significant increase was found in case of SCG premedication (mean change in μg/mmol creatinine): 2 mg/20 min: +12.1; 2 mg/120 min: +8.5; 10 mg/20 min: −10.4 and 10 mg/120 min: −23.5; P 〉 0.1). Conclusion Administration of 10 mg of sodium cromoglycate is no more effective in preventing exercise-induced bronchoconstriction than 2 mg regardless of whether the medication is given 20 or 120 min before exercise. The preventive effect of sodium cromoglycate on exercise-induced bronchoconstriction in asthmatic children is associated with the inhibition of urinary eosinophil protein X excretion.

    Notes: Abstract Intensive multimodality treatment has led to a remarkable improvement of prognosis in paediatric cancer patients, however, a great number of long-term survivors suffer from considerable tumour- or treatment-related late effects. Between January 1990 and December 1998, 223 consecutive survivors of childhood malignancies entered a prospective follow-up study designed to evaluate the frequency and severity of tumour- and/or therapy-related long-term sequelae. After cessation of therapy and subsequently once a year, all patients underwent a detailed examination programme including physical examination, laboratory tests, abdominal sonography, echocardiography, electrocardiography, electroencephalography, spirometry, audiometry, ophthalmological examination and endocrine stimulation tests. Median follow-up was 5 years (range 0.4 to 9.6 years). A total of 167 patients (75%) had at least one chronic medical problem of whom 80 needed permanent medical support. The organ systems most frequently affected were the nervous system in 39%, the endocrine system in 32%, the ears/eyes in 22%, the kidneys in 17%, and the liver in 12% of the patients. Some late effects (endocrine deficits, hearing loss, tubulopathy) were primarily diagnosed only several years after the end of oncological therapy. Conclusion The results of this study indicate that a considerable number of former paediatric cancer patients suffer from remarkable long-term side-effects. Since life quality is an important parameter of cancer survival, careful follow-up of long-term survivors is mandatory with the aim to reduce or even abrogate possible side-effects at the earliest time.

    Notes: Abstract Steady progress in developing effective treatments for childhood cancer and other severe pediatric diseases has established the need to consider the nature and frequency of late physical and psychological effects. The Health Utilities Index Mark 2 and Mark 3 (HUI2/3) systems were developed by Feeny, Furlong, Torrance et al. in Canada. These systems are generic multi-attribute measures of a person's health status and health-related quality of life. The first German version of the Canadian HUI2/3 questionnaire was created in our clinic, following recommended guidelines for cross-cultural adaptation of health-related quality of life measures. The usefulness of the resultant version was investigated using a sample of 142 patients who presented to our oncological outpatients' department for a routine health care visit after completion of treatment. The 15 items of the HUI2/3-questionnaire were answered independently by three groups of assessors – nurses, physicians, and parents or patients. Two additional questions covered ratings of the severity of treatment effects and the specification of these effects. The questionnaire was both easy to use and acceptable to the assessors. Percentage agreement between observers about levels for individual attributes ranged from 56% to 100%, with the lowest agreement on the subjective attributes of emotion, pain and cognition. These results are in accordance with previous studies using the original instrument. HUI2 global utility scores were significantly related to ratings of treatment sequelae, giving support to the discriminant validity of the measure. Conclusion The German version of HUI2/3 is a useful instrument with generally high inter-observer agreement and good suitability for outcome measurement in childhood cancer patients. Further research is needed to assess the usefulness of the instrument in other clinical populations and its sensitivity in longitudinal studies.

    Notes: Abstract Osteogenesis imperfecta (OI) is a genetic disorder of connective tissue. Progressive hearing loss is one of the principal symptoms of OI, affecting about 50% of adult patients. Hearing loss may also occur in childhood and results in additional disability in education and psychosocial adaptation and aggravates the physical handicap. This can be avoided by appropriate otological and audiological treatment. In a nationwide search, 254 Finnish patients with OI were identified indicating a prevalence of 4.9/100 000. Of the 60 children, 45 aged between 4 and 16 years accepting to participate the study on hearing, were evaluated by a questionnaire and clinical audiometry. Hearing loss was defined as pure tone average (PTA0.5–2 kHz) more than 20 dB hearing level (HL). A clinical geneticist determined the type of OI among the 45 patients. Two sporadic OI cases with conductive hearing loss were ascertained (4.4%): An 11-year-old girl with type IV OI with a PTA0.5–2 kHz of 35/40 dB HL and a 15-year-old boy with type IV OI with a PTA0.5–2 kHz of 27/18 dB HL. In addition, a 6-year-old girl with familial OI type I had either a congenital sensorineural deafness or early progressive deafness with PTA0.5–2 kHz of 97/103 dB HL, probably of unrelated aetiology. Conclusion Hearing loss in children with osteogenesis imperfecta is less frequent than generally suspected. Nevertheless, it is recommended that audiometry is performed in children with osteogenesis imperfecta even without symptoms of hearing loss at the age of 10 years, and repeated every 3 years thereafter.

    Notes: Abstract Enalapril, a long-acting inhibitor of angiotensin-converting enzyme, was given for 2 years to seven children with Alport syndrome. Five patients had a classical X-linked form of the disease; two siblings had the autosomal recessive variant. Their age was between 5.15 and 13.75 years when enalapril was started. All patients had haematuria and proteinuria, creatinine clearance was 〉80 ml/min per 1.73 m2 in all, and only one patient was hypertensive. The starting dose of enalapril (0.1 mg/kg body weight per day) was increased progressively according to individual clinical tolerance. The median doses were 0.13, 0.12, 0.21 and 0.29 mg/kg at 6, 12, 18 and 24 months, respectively. Median values of mean blood pressure were 95 mmHg at the start and 84 mmHg after 24 months. Median daily proteinuria decreased from 52 mg/kg to 18 mg/kg at 6 months, 21 mg/kg at 12 months, 12 mg/kg at 18 months and 30 mg/kg at 24 months. Serum creatinine increased over time from a median of 0.64 mg/dl at baseline to 0.77 mg/dl at 24 months. Concomitantly, there was a decrease in GFR from 104 to 83 ml/min per 1.73 m2 at 18 months and an increase again to 95 ml/min per 1.73 m2 at 24 months. Analysis of the individual data showed three patterns: no response (n=2), temporary response (n=2) and sustained response (n=3). Conclusion When given enalapril at the dosages mentioned, Alport patients as a group display a marked reduction in urinary protein excretion with a nadir of 23% of the baseline figure at 18 months, a decrease that cannot be accounted for by the slight decrease in glomerular filtration rate. Although these are preliminary data, it is recommended to try an angiotensin-converting enzyme inhibitor in every paediatric Alport patient with proteinuria.

As not only the HIV infection but also other disease-related factors might compromise growth in these children, growth data were analysed in a longitudinal cross-sectional manner in 84 HIV-negative haemophilic patients from two university clinics. A total of 2–24 height and weight measurements (median 6) were recorded in each patient resulting in 683 single values collected between 1977–1995. Height SDS of all haemophilic boys was −0.31 ± 2.13 (mean ± SD, NS versus 0) and body mass index SDS was 0.21 ± 3.49 (mean SD, NS versus 0) at first measurement and remained unchanged throughout the observation period. Neither height nor body mass index differed with respect to the severity of haemophilia (mild/moderate/severe) or the study centre (Vienna/Prague). Conclusion Growth in HIV-negative patients with haemophilia is not affected in spite of the immunological abnormalities attributed to the substitution therapy or the bleeding episodes in the joints with the potential effect on the growth plate.

    Notes: Abstract The introduction of combination antiretroviral therapy has been associated with a dramatic clinical improvement in children with human immunodeficiency virus infection. However, the uptake of antiretroviral therapy has been variable across Europe. The Paediatric European Network for the Treatment of AIDS Steering Committee has performed a systematic literature review of paediatric antiretroviral therapy trials. An analysis of the evidence base for the commencement and maintenance of antiretroviral therapy was produced. Suggestions for when to commence antiretroviral therapy, which drugs to start with and how to monitor and sequence drug regimens are given. Conclusion The aim of these guidelines is to help in obtaining equity of access to a uniformly high standard of care for children with human immunodeficiency virus infection in all European countries.

    Notes: Abstract The pharmacokinetics of the novel, rapid-acting insulin aspart were compared with those of soluble human insulin following subcutaneous administration in nine children (aged 6–12 years) and nine adolescents (aged 13–17 years) with stable type 1 diabetes. The study had a randomised, double-blind, two-period crossover design. Each patient received a single subcutaneous dose of insulin aspart or human insulin (0.15 IU/kg body weight) 5 min before breakfast and the plasma insulin and glucose concentrations were measured at intervals during the following 5 h. The pharmacokinetic profile of insulin aspart differed significantly from that of human insulin with a higher mean maximum serum insulin (Cmax ins), 881 ± 321 (SD) pmol/l versus 422 ± 193 pmol/l for human insulin (P 〈 0.001); and with a shorter median serum insulin t max ins, 40.0 min (interquartile range: 40–50 min) versus 75.0 min (interquartile range: 60–120 min) for human insulin, (P 〈 0.001). An age-related effect on Cmax ins and area under the curve (AUC0–5h ins) was observed with higher values in adolescents than in children for both insulin aspart and human insulin. Postprandial glycaemic control was improved with insulin aspart; the baseline-adjusted ΔCmax glu being lower for insulin aspart compared with human insulin (increase of 7.6 ± 5.1 versus 9.4 ± 4.4 mmol/l respectively, P 〈 0.05). The incidence of adverse events was similar for the two insulin types. Conclusion The more rapid onset of action of insulin aspart versus human insulin, previously observed in adults, is confirmed in a paediatric population with type 1 diabetes.

    Notes: Abstract A 12-year-old boy presented with a limp and findings suggesting localised myositis of his right calf and a working diagnosis of Behçet disease was made. During 3 years of follow-up, he had another three episodes of calf myositis, all responsive to corticosteroids within days. Conclusion A case of recurrent localised myositis as a main manifestation of Behçet disease is reported. The evolution of incomplete Behçet disease, which is common in children, to the full blown form, with the emphasis on muscle involvement and the importance of early diagnosis of Behçet disease, is discussed.

    Notes: Abstract Reports on schistosomiasis in children growing up in Europe are rare despite increased travel activity. We report on eight male and three female German children aged 50 months to 15 years with schistosomiasis. Six children were asymptomatic, whereas two presented with typical signs of Katayama fever. Persisting haematuria, headache with eosinophilia and pyelonephritis were observed in one child each. An exposure was reported for six of the children. Two were examined solely because schistosomiasis was diagnosed in a family member. All had antibodies against schistosomal antigens in at least two of three screening tests. However, schistosomal ova (Schistosoma haematobium) were detected in urine and faecal specimens from only three children. A tumour-like lesion of the bladder was found by ultrasound in only one of the children who also exhibited haematuria. Neither eosinophilia nor elevated IgE levels were constant findings. Six to 12 months after praziquantel treatment, parasitological and ultrasound checks were negative and levels of specific antibodies decreased. However, 2 years later, elevated antibody levels were detected in one girl without evidence of any new exposure. She became antibody-negative 1 year after a second course of treatment. Conclusion In contrast to residents of endemic areas, parasitological and ultrasound examinations seem to be inferior to immunodiagnostics in children from non-endemic areas at temporary risk for schistosomiasis.

    Description / Table of Contents: Abstract Thrombangiitis obliterans (Buerger disease) is a rare vascular disease, characterized by a multilocular, segmental, non-arteriosclerotic, thrombotic inflammation of small and medium size arterial and venous vessels and nerves. The precise etiology is unknown, but there is a cause-effect relationship with tobacco smoking. Autoimmunological, immunogenetical, infectious and hemostatic processes have been discussed as pathogenetic factors. The clinical picture is typically characterized by acrally localized, non-healing ulcerations, which frequently prompt patients to see a dermatologist. We present two patients with thromboangiitis obliterans and discuss the clinical features, the resulting differential diagnostic spectrum and possible therapeutic approaches.
    Notes: Zusammenfassung Die Thrombangiitis obliterans (Morbus Winiwarter-Buerger) ist eine seltene Gefäßerkrankung, die durch eine segmentale, multilokuläre, nichtarteriosklerotische, thrombosierende Entzündung der kleinen und mittleren Arterien und/oder Venen und Nerven charakterisiert ist. Die Ätiologie ist bis heute unklar. Es besteht ein kausaler Zusammenhang mit starkem Tabakkonsum. In der Literatur werden autoimmunologische, immungenetische, infektiöse oder hämostaseologische Ursachen diskutiert. Klinisch zeigt sich oftmals das Bild einer distalen arteriellen Ischämie mit einer akral gelegenen Ulzeration ohne Heilungstendenz. Viele Patienten suchen im Laufe einer progredienten, noch nicht diagnostizierten Thrombangiitis obliterans eine fachdermatologische Einrichtung auf. Anhand zweier Kasuistiken werden das Krankheitsbild, die differentialdiagnostische Bandbreite und die möglichen Therapieansätze dargestellt.

    Description / Table of Contents: Abstract Background and Objective. Psychological problems in children and parents related to children's atopic eczema (AE) may impede the success of treatment. We studied the question, if behavior-based parental education in groups (DPE) or standardized video-education (VPE) could enhance dermatological treatment effects and reduce skin-damaging behaviors in children and stress in their mothers. Patients/Methods. 47 mothers attending the university outpatient-clinic for dermatology and their AE-children (mean age 4 years) participated in the study. 18 mothers underwent the DPE (10 sessions), 15 mothers worked with VPE at home. Dermatological standard treatment (CG; N=14) served as control for a 16-weeks-evaluation-period. Results. AE-symptoms improved overall, but the effectiveness of the treatments differed significantly, improval with parent education and was best with VPE. Psychological problems of mothers were equally reduced with DPE and VPE. Conclusions. It is suggested that VPE is a cost effective and less time consuming method for supporting dermatological therapy of AE in children.

Das atopische Ekzem (AE) im Kindesalter kann psychologische Probleme bei Kind und Eltern zur Folge haben, die den Behandlungserfolg erschweren. Die Effektivität direkter verhaltensorientierter Elterngruppenschulungen (DES) bzw. standardisierter Videoschulungen (VES) gegenüber der dermatologischen Standardbehandlung (KG) zur Besserung des AE, des Kratzverhaltens der Kinder und krankheitsbedingter Belastungen der Mütter wurde überprüft. Patienten/Methodik. An der Studie nahmen 47 Mütter und deren AE-Kinder (Durchschnittsalter 4 Jahre) aus der Neurodermitisambulanz der Universitätshautklinik teil, 18 Mütter besuchten die DES (10 Gruppensitzungen), 15 Mütter arbeiteten mit der VES zu Hause. Die Behandlung der KG (n=14) erfolgte im vergleichbaren 4-Monats-Zeitraum. Ergebnisse. Das AE war über alle Behandlungsbedingungen gebessert, ihre Effekstärken unterschieden sich jedoch signifikant: Elternschulungen waren effektiver als Standardbehandlung, den stärksten Effekt hatte die VES. Belastungen der Mütter reduzierten sich nach beiden Schulungsformen. Schlussfolgerungen. Die Ergebnisse verweisen auf eine Zeit und Kosten sparende Möglichkeit, Videoschulungen für die Unterstützung der Therapie des AE im Kindesalter zu nutzen.

    Description / Table of Contents: Abstract Background and Objective. In spite of the importance of skin diseases in Africa south of the Sahara, dermatology is insufficiently represented within the established primary health care systems. Aim of this study was to find out whether an integrated dermatology project could reduce the prevalence of dermatoses. Patients/Methods. Since 1994 trained community health workers have carried out regular weekly visits to schools and nurseries in 10 communities in rural western Kenya. Epidemiological studies were done in 13 schools in 4 communities involving 5780 and 4961 pupils one year before (1993) and 5 years (1999) following the introduction of the dermatology project. Results. Within this period the prevalence of bacterial skin infections fell from 12.7% to 11.3% (n.s.). Mycoses rose from 10.1% to 13.9% (p〈0.05), while arthropod infections (mainly scabies) remained unchanged with a prevalence of 8.3% in 1993 and 8.0% in 1999 (n.s.). Dermatitis also showed no changes (1.7% in both years). Conclusions. The prevalence of infective dermatoses depends not only on medical treatment but also far more on socio-economic factors.
    Notes: Zusammenfassung Hintergrund und Fragestellung. Trotz der großen Bedeutung der Dermatosen in Schwarzafrika ist die Dermatologie in den dort etablierten Basisgesundheitsdiensten völlig unzureichend repräsentiert.

Seit 1994 besuchen ausgebildete Community Health Workers einmal wöchentlich Schulen und Vorschulkindergärten in 10 Gemeinden im ländlichen Westkenia. In 13 Schulen von 4 Gemeinden wurden 1 Jahr vor (1993) und 5 Jahre nach (1999) Projektinitiierung Reihenuntersuchungen an 5780 bzw. 4961 Kindern durchgeführt. Ergebnisse. Innerhalb dieses Zeitraums sank die Prävalenz bakteriell bedingter Dermatosen von 12,7% auf 11,3% (n.s.). Bei den Mykosen fand sich ein Anstieg von 10,1 auf 13,9% (p〈0,05). Arthropodenbedingte Infektionen (vorwiegend Skabies) blieben mit 8,3% 1993 und 8,0% 1999 (n.s.) im Wesentlichen gleich. Ekzeme wiesen zu beiden Zeitpunkten eine Prävalenz von 1,7% auf. Schlussfolgerungen. Die Prävalenz infektiöser Dermatosen hängt nur zu einem geringen Teil von der medizinischen Versorgung, sondern überwiegend von sozioökonomischen Faktoren ab.

    Notes: Abstract  Ectopic pregnancy is a implantation occurring elsewhere than in the cavity of the uterus, whereas nintynine percent of extrauterine pregnancies occur in the fallopian tube. The incidence of extrauterine pregnancy has increased from 0.5% thirty years ago, to a present day 1–2%. The most frequent cause of tubal pregnancy is previous salpingitis. Mortality rates for tubal pregnancies used to be approximately 1.7% in the 1970 s but dropped to 0.3% in 1980 s. Diagnosis: Using transvaginal ultrasound it is possible to obtain positive evidence of an ectopic pregnancy at a very early stage. In cases of hCG titers〉2000 IU/l, intrauterine pregnancy can be diagnosed with certainty. The most important differential diagnosis of ectopic pregnancy is early intrauterine pregnancy. Clinical management and therapy: Regardless of the therapeutic strategy selected by the physician, informing the patient is a major aspect of the management of ectopic pregnancy. If surgery is considered appropriate, the patient must be informed about the nature, side effects and complications of the procedure. However, it should be remembered that in some cases, the actual chances of cure first become apparent at surgery. In asymptomatic patients with a serum hCG titer 〈1000 IU/l that is falling, it is appropriate to wait and watch. In clinically stable patients with an unruptured tubal pregnancy and steady hCG levels, systemic treatment with methotrexate might also be considered. In unruptured tubal pregnancy with a hCG titer between 1000 and 2500, a further therapeutic alternative is intratubal injection of prostaglandins, hyperosmolar glucose of NaCl. Generally speaking, the currently widespread laparoscopic surgical treatment of the fallopian tube hardly influences the risk of recurrence. If the gestational mass is larger, the serum hCG titer higher than the approximate limit of 2500 mU/ml and/or the tube already ruptured, surgery is usually required. Prevention: The most effective prevention is to avoid tubal inflammation or, in cases of preexisting inflammation, to administer effective therapy.

    Notes: Abstract The linkage between HLA antigens and disease susceptibility has been investigated in several diseases. Two different mechanisms are known to act in the relation between the HLA system and headache: linkage and association of alleles. Among neurological disorders associated with coeliac disease (CD) we focused on headache in 1997. From a group of 70 coeliac children, we studied 10 children with headache (3 boys and 7 girls). For each subject we evaluated clinical history and HLA antigens. The incidence of headache was not different with respect to the prevalence of headache in the general population. The HLA setting is not different between the 2 groups examined. However, we highlight 2 cases for the particular HLA setting.

    Notes: Abstract In our previous study we found a high prevalence of disordered sleep breathing in migraine children vs. controls. Since no quantitative studies about sleep respiratory disorders have been carried out in migraine children, we performed a polysomnographic (PSG) study in 10 migraine patients (7 boys, 3 girls; mean age 8.11 years, range, 5.8–14.5) attending the Headache Center of our department, to evaluate the presence of sleep apnea. Mothers completed a headache diary and a sleep diary for at least 1 month and filled out a sleep questionnaire. PSG data showed a normal sleep architecture in 3 cases, an insomnia pattern in 2, a reduction of slow wave sleep in 3 and a reduction of REM sleep in 2. Respiratory analysis revealed that 2 of 10 patients had obstructive sleep apnea. These 2 patients presented habitual snoring and associated sleep disturbances such as restless sleep and hypnic jerks. Sleep apnea may be a subtle and often undiagnosed symptom in several migraine patients. The report of habitual snoring associated with other sleep disturbances such as restless sleep and other parasomnias may be a sign of sleep apnea in migraine children.

    Description / Table of Contents: Abstract Despite the progress, which has been made in diagnosis and therapy of encephalitis and bacterial meningitis, these acute inflammatory diseases of the brain still display a certain amount of morbidity and mortality. History, physical examination, analysis of serum and cerebrospinal fluid and radiological examination are the mainstay for the diagnosis of these diseases. With respect to the acute inflammatory diseases of the brain computed tomography and magnetic resonance imaging fulfill three purposes: 1. They can be used to clarify the diagnosis and to rule out other diseases. 2. They can identify the focus from which a bacterial meningitis can evolve. 3. Complications like edema, cerebral vasculitis, septic sinus thrombosis, hydrocephalus or abscess can be visualized. If the diagnosis is made early, the possible complications are recognized in good time and the appropriate therapy is started immediately, then morbidity and mortality can be kept at a minimum.
    Notes: Zusammenfassung Die bakterielle Meningitis und die Enzephalitis sind akut-entzündliche Hirnerkrankungen, die trotz aller Fortschritte in der Diagnostik und Therapie mit einer nicht unerheblichen Morbidität und Mortalität behaftet sind. Die Anamnese, die körperliche Untersuchung, die laborchemische Diagnostik von Blut und Liquor und die Bildgebung sind die wesentlichen Säulen in der Diagnostik akut-entzündlicher Hirnerkrankungen. Die Bildgebung, die mittels Computertomographie bzw. Kernspintomographie erfolgt, hat in diesem Zusammenhang 3 Aufgaben: 1. Sie kann dazu beitragen, die Diagnose zu sichern bzw. differentialdiagnostisch in Erwägung zu ziehende Erkrankungen auszuschließen oder nachzuweisen. 2. Sie kann bei der bakteriellen Meningitis entzündliche Foci im Bereich der Nasennebenhöhlen, des Mastoids oder des Mittelohrs erkennen, die sofort operativ saniert werden müssen. 3. Komplikationen akut-entzündlicher Hirnerkrankungen können bei entsprechendem klinischem Verdacht mittels Bildgebung nachgewiesen werden. Hirnödem, vaskulitische Infarkte, septische Sinusthrombose, Hydrozephalus oder Abszess stellen die wesentlichen Komplikationen dar, die zur Morbidität und Mortalität akut-entzündlicher Hirnerkrankungen beitragen und die umgehend mit einer spezifischen Therapie angegangen werden müssen.

    Description / Table of Contents: Abstract Background. In the interdisciplinary Pain Conference, pain specialists of various disciplines discussed – partly in the presence of the concerned patient – explanations as to the cause of a specific pain. The following example portrays the events of the conference. Case report. In this case, despite extensive diagnostics, no explanation due to an organ failure could be found for a 74-year-pld man with worsening neurological pain above the knee. The patient's desire the change was so strong that after ineffective outpatient care and different operations, such as hernitomy, fibroma removal and the implantation of an epidural stimulating electrode (SCS), other inpatient pain therapies followed using anasthesiological, balneophysical and psychological techniques, as well as medications. Diagnosis and therapy. The interdisciplinary discussion, including all the various diagnostical findings and the results of the therapeutical efforts, lead to the decision by conference participants to use the new electrophysical and imaging diagnostics. This lead to the discovery of a leiomyosarcoma, which had surrounded the N. obtoratius. After the removal surgery, the pain was gone and the pain medications being used could gradually be dropped.

Bei dem vorgestellten Fall handelt es sich um einen 74-jährigen Mann mit einem über Jahre stärker werdenden neuralgischen Oberschenkelschmerz, der trotz umfangreicher Diagnostik keinem organischen Korrelat zugeordnet werden konnte. Der Leidensdruck des Patienten war so erheblich, dass nach ineffektiven ambulanten Behandlungsversuchen verschiedene Operationen wie Herniotomie, Fibromentfernungen und die Implantation einer epiduralen Stimulationselektrode (SCS) sowie wiederholte stationäre schmerztherapeutische Interventionen mit anästhesiologischen, balneophysikalischen und psychologischen Techniken und medikamentösen Konzepten erfolgten. Diagnose und Therapie. Der interdisziplinäre Austausch, die differenzialdiagnostische Sichtung sämtlicher Befunde unter Einschluss der Ergebnisse bisheriger therapeutischer Bemühungen führte zum Beschluss der Konferenzteilnehmer, eine erneute differenzierte elektrophysiologische und bildgebende Diagnostik durchzuführen. Diese führte zur Aufdeckung eines Leiomyosarkoms, welches den N. obturatorius ummauerte. Nach operativer Entfernung stellte sich Schmerzfreiheit ein, sodass die bisherige Schmerzmedikation allmählich abgesetzt werden konnte.

    Notes: Abstract Abstract A randomized field trial of a child-centered model of training for self-management of chronic illnesses was conducted of 355 Spanish-speaking school-aged children, between 6 and 15 years old, with moderate to severe asthma and epilepsy, in Buenos Aires, Argentina. The model, based on play techniques, consists of five weekly meetings of 8–10 families, with children's and parents' groups held simultaneously, coordinated by specially trained teachers and outside the hospital environment. Children are trained to assume a leading role in the management of their health; parents learn to be facilitators; and physicians provide guidance, acting as counselors. Group activities include games, drawings, stories, videos, and role-playing. Children and parents were interviewed at home before the program and 6 and 12 months after the program, and medical and school records were monitored for emergency and routine visits, hospitalizations, and school absenteeism. In asthma and epilepsy, children in the experiment showed significant improvements in knowledge, beliefs, attitudes, and behaviors compared to controls (probability of experimental gain over controls=.69 for epilepsy and .56 for asthma, with σ2= .007 and .016, respectively). Parent participants in the experiment had improved knowledge of asthma (39% before vs. 58% after) and epilepsy (22% before vs. 56% after), with a probability of gain=.62 (σ2=.0026) with respect to the control group. Similar positive outcomes were found in fears of child death (experimental 39% before vs. 4% after for asthma, 69% before vs. 30% after for epilepsy), as well as in disruption of family life and patient-physician relationship, while controls showed no change. Regarding clinical variables, for both asthma and epilepsy, children in the experimental group had significantly fewer crises than the controls after the groups (P=.036 andP=.026). Visits to physicians showed a significant decrease for those with asthma (P=.048), and emergency visits decreased for those with epilepsy (P=.046). An 18-item Children Health Locus of Control Scale (CHLCS) showed a significant increase in internality in experimental group children with asthma and epilepsy (P〈.01), while controls did not change or performed worse 12 months after the program. School absenteeism was reduced significantly for those with asthma and epilepsy (for the group with asthma, fall/winterP=.006, and springP=.029; for the group with epilepsy,P=.011). Conclusion The program was successful in improving the health, activity, and quality of life of children with asthma and epilepsy. The data suggested that an autonomous (Piagetian) model of training is a key to this success, reinforcing children's autonomous decision making.

    Description / Table of Contents: Summary Most craniofacial malformations result from a premature fusion of skull sutures. Depending on the scope of the sutures affected, the results are more or less distinct deformations of the facial and cranial skull with substantial negative effects on functional as well as esthetic aspects. The etiopathology is still unclear. Various therapies have been developed over the past 100 years. However, Tessier’s technique of fronto-orbital advancement has been an important milestone in the treatment of these malformations. Numerous adjustments have since perfected this operational technique. It is now possible to treat practically all skull malformations with the surgical techniques available today. At the same time, these techniques have also aided the advancements in tumor surgery and traumatology.
    Notes: Zusammenfassung Kraniofaziale Fehlbildungen entstehen überwiegend durch die vorzeitige Verknöcherung von Schädelnähten. Je nach Nahtbefall resultieren daraus mehr oder weniger ausgeprägte Deformationen des Hirn- und Gesichtsschädels, die sowohl zu einer funktionellen als auch zu einer ästhetischen Beeinträchtigung führen. Die Ätiopathogenese ist noch weitgehend ungeklärt. In den vergangenen 100 Jahren wurden verschiedene Therapieansätze entwickelt, wobei Tessier mit der Technik des frontoorbitalen Advancements der entscheidende Fortschritt gelang. Aufbauend auf dieser Operationstechnik wurden bis heute zahlreiche Verbesserungen eingebracht. Mit den heutigen Operationstechniken ist es möglich, praktisch alle Schädelfehlbildungen zu therapieren. Gleichzeitig konnten durch diese Techniken auch Fortschritte in der Tumorchirurgie und der Traumatologie erzielt werden.

    Description / Table of Contents: Summary The presentation of vascular and neural malformations in an understandable terminology permits accurate diagnosis, proper treatment, individualized prognosis, and also stimulates studies of pathogenesis. The descriptive classification includes: NF 1 and NF 2; hemangiomas, low- and high-flow vascular malformations, combined malformations, and hypertrophy; and syndromes such as, Parkes Weber, Klippel-Trénaunay, Maffuci’s, and multiple dysplasia syndromes. Lymphatic malformations are abnormalities of lymphatic development. The list of treatment includes surgical and nonsurgical treatment. Not all vascular malformations can be successfully treated. Coping with NF is a challenge for both, affected individuals and health care professionals. NF is often associated with a myriad of anomalies that present a lot of problems for plastic surgery. In certain cases watchful waiting seems justified but not in cases of severe problems, giant growth, and local complications.
    Notes: Zusammenfassung Die Frage der Terminologie ist im Zusammenhang mit vaskulären und nervalen Malformationen besonders wichtig. Dies gilt nicht nur im Hinblick auf die Wahl des richtigen Therapieverfahrens, sondern auch im Hinblick auf die individuell ausgerichtete Prognose und natürlich auch zur Beantwortung der die Pathogenese betreffenden Fragen. Es ist klar, dass bei Besprechung der Neurofibromatose zunächst an die NF 1 und NF 2 gedacht wird, die Hämangiome werden entsprechend ihrer Durchblutung und auch im Hinblick auf die Kombination mit den so ¶genannten Hypertrophiesyndromen, die später im Text genannt werden, eingeteilt. Dass die Bezeichnung Lymphangiom impliziert, es handle sich um einen Tumor, mag nicht ganz richtig sein, da anscheinend die für Tumoren üblichen Mitosen vermisst werden. Interessant ist das therapeutische Spektrum und dies gilt für alle Malformationen der Gefäße und Nerven, aber ganz besonders natürlich für die Neurofibromatose und die Hämangiome. Mit der NF konfrontiert zu sein, bedeutet für den Patienten und das ärztliche Personal eine lebenslange Herausforderung, darüber hinaus ist die NF häufig mit einer Unzahl von Einzelproblemen vergesellschaftet, die für die plastische Chirurgie z. T. schwere oder nicht zu lösende Probleme darstellen. Die große Zahl an Therapievorschlägen zeigt, dass die Gefäßmalformationen zum einen sehr unterschiedliche Probleme zeigen, und zum anderen, dass es kaum ein Therapieverfahren gibt, welches keinen Wunsch offen lässt. Wichtig ist der Hinweis, dass schnell wachsende Hämangiome durchaus im Anfangsstadium entfernt werden sollten, zuwartende Haltung ist in bestimmten Fällen gerechtfertigt, aber nicht, wenn sich schwere Probleme, Riesenwachstum und lokale Komplikationen einstellen.

    Description / Table of Contents: Summary Among mandibular fractures, those of the condylar neck hold a special position due to the exceptional anatomical situation. Computer assisted tomography and magnetic resonance tomography have improved diagnostic evaluation. Indication for surgical treatment is given in cases of severely displaced or dislocated fractures. In surgical management, the preauricular, submandibular, retromandibular, and oral approach have been established. For sufficient fixation of fragments, procedures rendering a functional stability, like osteosynthesis with lag screw or by miniplating, are required.
    Notes: Zusammenfassung Die Gelenkfortsatzfrakturen nehmen aufgrund der besonderen anatomischen Situation eine Sonderstellung innerhalb der Unterkieferfrakturen ein. Die Computertomographie und das MRT haben die Diagnostik wesentlich verbessert. Die Indikation zur operativen Behandlung besteht bei stark dislozierten oder luxierten Frakturen. Als operativer Zugang sind der präaurikuläre-, sub- bzw. perimandibuläre, retromandibuläre und orale Zugang etabliert. Zur Fixation der Fragmente sollten ausschließlich funktionsstabile Verfahren, wie die Miniplatte oder Zugschraube verwendet werden.

    Notes: Abstract  The purpose of this study was to investigate the influence of age on the severity of dental fluorosis in children exposed to drinking water with either low or high fluoride concentrations. The children selected for this study were aged 10–14 years, with 28 permanent teeth and at least 1 tooth pair with fluorosis. The children were permanent residents of districts in western Uganda with either 0.5 mg (n=33) or 2.5 mg fluoride/l in drinking water (n=186). All vestibular tooth surfaces were examined for fluorosis using the modified Thylstrup and Fejerskov (TF) index. In the high fluoride community, the proportion of teeth per child with TF scores ≥4, and ≥5 was significantly higher among children aged 13–14 years compared to those aged 10–12 years. Children’s chronological age correlated positively and significantly with the median TF scores for all teeth, including early erupting (first molars and incisors) and late erupting teeth (canines, premolars and second molars). In linear regression analyses, the median TF score for all teeth, as well as for early erupting and late erupting teeth, increased significantly with age. On the other hand, in the low fluoride community there was no significant association between age and the severity of fluorosis. This study showed a significant increase in the severity of fluorosis with increasing age in a high fluoride community, whereas no change in severity with age was observed in a low fluoride community.

    Description / Table of Contents: Abstract Accident insurance agencies are confronted with an increasing number of cases in which psychological damage occurs immediately at the time of the traumatic events, or in their aftermath. This article reviews the stipulations governing insurance cover and benefits and the legal principles of causality issues in the case of psychological traumas and disorders resulting from such incidents. Insurance agencies face special challenges for case mangagement, since there are no well-established procedures for physicians and hospitals to follow in such cases. Irrespective of the often difficult causality and liability issues, immediate therapy should be given absolute priority. More attention should be paid to psychological damage, with the aims of improving methods of medical rehabilitation and establishing guidelines for expert review in such cases.
    Notes: Zusammenfassung Die Unfallversicherungsträger sind mit einer zunehmenden Zahl von Fällen konfrontiert, bei denen psychische Gesundheitsschäden unmittelbar bei dem Unfallereignis auftreten oder sich nachfolgend entwickeln. Der Beitrag gibt einen Überblick über Grundsätze des Versicherungsschutzes und Kausalitätsfragen bei psychischen Traumen und psychischen Störungen als Folge eines Versicherungsfalls. Für die Unfallversicherungsträger ergeben sich besondere Anforderungen an die Steuerung des Heilverfahrens, da nicht auf das für organische Verletzungen etablierte System besonderer Heilverfahrensarten, wie z. B. das Durchgangsarztverfahren, zurückgegriffen werden kann. Unter allen Umständen hat die Therapie unbedingten Vorrang, unabhängig von der kausalrechtlichen Fragestellung nach dem zuständigen Leistungsträger. Psychischen Gesundheitsschäden ist vermehrt Aufmerksamkeit zu schenken mit dem Ziel, geeignete Maßnahmen der medizinischen Rehabilitation weiterzuentwickeln und Konventionen für die Begutachtung zu schaffen.

    Description / Table of Contents: The injuries that typically accompany pelvic fractures are lesions of the urogenital tract, the lumbosacral plexus, and the retroperitoneal and intra-abdominal organs. The prognosis depends heavily on early recognition of the abdominal- and retroperitoneal injuries, which are frequently a primary threat to vital functions. Missing these injuries would be very serious, as the mortality with early diagnosis and adequate treatment is normally low; according to the results reported in the literature, delayed therapy leads to increasing mortality rates of up to 80%. Experience in trauma centres has shown that for complete ascertainment of accompanying injuries it is necessary to perform a systematic diagnosis according to a fixed algorithm. The treatment of the concomitant injuries accompanying a complex pelvic trauma is fundamentally different from the treatment of patients with isolated injuries. A high survival rate with a low postoperative complication rate cannot be achieved except with specialist surgical management tailored to the primary life-threatening lesions. After determination and recording of the injury pattern a therapy concept must be made at once. A trauma algorithm can be helpful when treatment is selected. Step-by-step treatment with several operative phases alternating with recovery and stabilization periods under intensive care conditions has proved worthwhile.
    Notes: Typische Begleitverletzungen von Beckenfrakturen sind Verletzungen des Urogenitaltrakts, des Plexus lumbosacralis und intraabdominaler Organe. Entscheidend für die Prognose ist das rechtzeitige Erkennen v. a. der häufig primär vital gefährdenden Abdominal- und Retroperitonealverletzungen. Das Übersehen dieser Verletzungen ist besonders tragisch, da bei rechtzeitiger Diagnostik und adäquater Versorgung die Letalitätsrate in der Regel gering ist; bei verzögerter Therapie resultieren nach den Angaben in der Literatur Letalitätsraten bis zu 80%. Die Erfahrung in Traumazentren hat gezeigt, dass zur vollständigen Erfassung der Begleitverletzungen die systematische Diagnostik nach einem festgelegten Algorithmus erfolgen sollte. Die Behandlung der Begleitverletzungen im Rahmen eines komplexen Beckentraumas unterscheidet sich prinzipiell von der bei Monoverletzten. Voraussetzung für eine hohe Überlebensrate mit geringer postoperativer Komplikationsrate ist ein prioritätenorientiertes chirurgisches Vorgehen. Nach Erfassung des Verletzungsmusters muss bereits initial ein Therapiekonzept erstellt werden. Zur Entscheidungsfindung kann ein Traumaalgorithmus herangezogen werden. Es hat sich eine abgestufte Versorgung mit mehreren operativen Phasen und zwischengeschalteten Erholungs- und Stabilisierungsphasen unter Intensivbedingungen bewährt.

    Description / Table of Contents: The particular injury pattern of complex joint trauma means that a standardized operative procedure would be difficult to devise and an individual therapy plant is therefore essential for each patient. One of the main problems consists in the recognition and adequate treatment of associated vascular and neural lesions. The treatment of a complex joint trauma makes extremely high demands on the trauma-team in terms of both diagnostis and therapy and is an interdisciplinary challenge. On the basis of a detailed literature search and evaluation of the procedures we have adopted in sample cases, we suggest an algorithm for interdisciplinary management of severe combination injuries of the shoulder region.
    Notes: Die Problematik des komplexen Gelenktraumas besteht darin, dass aufgrund des besonderen Verletzungsmusters ein standardisiertes operatives Vorgehen erschwert und deshalb ein individuelles Therapiekonzept essenziell ist. Ein Hauptproblem besteht in ¶der Erkennung und der adäquaten Behandlung assoziierter Gefäß- und Nervenläsionen. Die Behandlung eines komplexen Gelenktraumas stellt höchste diagnostische und therapeutische Ansprüche an das Traumateam und bedeutet eine interdisziplinäre Herausforderung. Aufgrund einer eingehenden Literaturrecherche und der Auswertung des eigenen Vorgehens anhand exemplarisch ausgewählter Fälle wird versucht, einen Algorithmus der interdisziplinären Komplexversorgung schwerer Kombinationsverletzungen der Schulterregion zu erstellen.

    Description / Table of Contents: In this paper we describe the tarsal tunnel syndrome with reference to our own experience in 10 cases and the literature. Compared with the numerous injuries involving the ankle and foot, the diagnosis of tarsal tunnel syndrome is rare. In the case of a painful foot of unknown aetiology, the differential diagnosis should therefore include tarsal tunnel syndrome. Our presentation discusses the aetiology and pathology of the tarsal tunnel syndrome, and particularly that caused by trauma. We also describe an effective therapeutic approach based on surgical decompression.
    Notes: Anhand der Literatur und eigenen Erfahrungen von 10 Operationen wird das Tarsaltunnelsyndrom dargestellt. Gemessen an der Vielzahl der Traumen im Sprunggelenk- und Fersenbeinbereich wird die Diagnose selten gestellt. Bei unklaren Fußschmerzen sollte daher differenzialdiagnostisch ein Tarsaltunnelsyndrom in Erwägung gezogen werden. Es wird auf die Ätiologie, die Pathologie sowie auf den Zusammenhang zu Traumen eingegangen und die effektive Therapie durch operative Dekompression beschrieben.

    Description / Table of Contents: Abstract Fractures and dislocations of the elbow are some of the most common injuries in childhood and adolescence. The majority occur in the course of sport and play, for example as the result of falling from apparatus used in gymnastics or a bike, or falling while engaging in such popular sports as in-line-skating or skateboarding. Elbow injuries can be divided into dislocations of the joint alone and fractures, of the distal humerus or the proximal radius and ulna, or combinations of both dislocation and fracture. In addition, a differentiation is made between extra- and intraarticular fracture types, the latter being seen as either partial or complete joint lesions.
    Notes: Zusammenfassung Luxationen und/oder Frakturen am Ellbogen gehören zu den häufigsten Verletzungen im Wachstumsalter überhaupt. Sie entstehen überwiegend bei Sport und Spiel, z. B. durch Sturz von einem Turngerät, von Zweirädern oder während der Ausübung moderner Sportarten wie In-line-Skating, Rollschuhlauf und Skateboardfahren. Bei den Verletzungen werden reine Luxationen von Frakturen entweder am körperfernen Oberarmende oder an den gelenkbildenden Anteilen von Radius und Ulna unterschieden. Ein weiteres Unterscheidungsmerkmal ist die Abgrenzung extraartikulärer von intraartikulären Frakturformen, wobei letztere entweder als partielle oder komplette Bruchform imponieren.

    Description / Table of Contents: Abstract Fractures of the head of the humerus present a challenge both at the stages of diagnosis and treatment. Fortunately, 70–80% ¶of all fractures of the humeral head can be treated conservatively because they are not dislocated. When dislocation is present detailed understanding of the morphology of such fractures and purposeful application of internal fixation techniques are essential for the achievement of good shoulder function. Every step of the treatment is aimed at stability of the joint with its components as close as possible to their original anatomical positions. This can generally be managed with minimally invasive approaches and/or with the bone fragments preserved. We regard depression fractures of the humeral head (〉 45%) in active, older patients –¶who are frequently affected – as a primary indication for a shoulder replacement. Four-fragment fractures with displacement of the head fragment in an older, physically active patient can also occasionally be an indication for primary joint replacement. Both for conservatively treated and for operatively treated fractures of the humeral head a customized schedule of follow-up treatment should be applied, to avoid the precipitation of secondary frozen shoulder by too-passive behaviour. On the other hand, neither should the follow-up treatment programme lead to a secondary dislocation. For restoration of the function it is therefore absolutely essential that the trauma surgeon monitor the treatments applied.
    Notes: Zusammenfassung Humeruskopffrakturen stellen eine Herausforderung an die Diagnostik und die Therapie dar. Glücklicherweise können 70–80% davon konservativ behandelt werden, da sie nicht disloziert sind. Im Fall der Dislokation sind ein differenziertes Verständnis der Frakturmorphologie und der zielgerichtete Einsatz osteosynthetischer Techniken unabdingbare Voraussetzung einer guten Schulterfunktion. Ziel jedweder Behandlungsmaßnahme ist das Erreichen einer stabilen Situation in möglichst anatomiegerechter Position. Dies kann überwiegend mit minimalinvasiven Zugängen bzw. unter Schonung der Knochenfragmente erreicht werden. Besonders im Fall der Humeruskopfimpressionsfrakturen (〉 45%) beim häufig betroffenen älteren, aktiven Patienten sehen wir eine primäre Indikation zur Schulterendoprothese. Ebenso stellen die 4-Fragment-Frakturen mit Verschiebung des Kopffragments bei älteren, biologisch aktiven Patienten eine gelegentliche Indikation zum primären Gelenkersatz dar. Sowohl für die konservativ als auch für die operativ behandelten Humeruskopffrakturen sollte ein differenziertes Nachbehandlungsschema Anwendung finden, um nicht durch zu passives Verhalten eine sekundäre Schultersteife zu initiieren. Auf der anderen Seite sollte ein Nachbehandlungsprogramm auch nicht zur sekundären Dislokation führen. Die unfallchirurgische Kontrolle der Behandlungsmaßnahmen ist daher zwingende Voraussetzung einer bestmöglichen Wiederherstellung der Funktion.

    Description / Table of Contents: Abstract Lesions of the anterior and posterior cruciate ligaments are relatively rare in childhood and adolescence; in this age group they need even more consistent and aggressive treatment than in adults as far as conservation of the menisci and definitive stabilization are concerned. Virtually no cases in which serious growth disturbance has arisen following transepiphyseal drilling are known from the literature. Thus, cruciate ligament suturing should also not be done in children, because the long-term efficacy has not been confirmed. The operative procedure is presented in detail and is related to bone age. Early transepiphyseal drilling is permissible.
    Notes: Zusammenfassung Ligamentäre Kreuzbandverletzung beim Kind und im Adoleszentenalter sind relativ selten, sie bedürfen im Vergleich zum Erwachsenen ¶einer noch konsequenteren und aggressiven Behandlung bezüglich Meniskuserhalt und definitiver Stabilisierung. In der Literatur sind praktisch keine Fälle bekannt, bei denen es tatsächlich zu einem gravierenden Fehlwachstum nach transepiphysärer Bohrung gekommen ist. Insofern sollte auch die Kreuzbandnaht beim Kind wegen der nicht bewiesenen Langzeiteffizienz unterlassen werden. Das Vorgehen im Einzelnen in Bezug zum Skelettalter wird dargestellt. Frühzeitige transepiphysäre Bohrungen sind erlaubt.

    Notes: Abstract  Since randomized controlled studies of severe acute human pancreatitis can be performed only with restrictions, at least some aspects of innovative therapy concepts should first be clarified in animal experiments. In vitro trials are inadequate for this purpose since they cannot simulate the complex course of severe acute pancreatitis. Animal test results can be transferred to clinical practice if the results are based on trials with established models, standardized methods, and a study design imitating the clinical situation. This contribution discusses the demands on such an animal model of acute pancreatitis and a corresponding study protocol and presents models and protocols which meet these requirements. Concrete examples are presented to show that animal experiments are of great value under these conditions, especially in acute necrotizing pancreatitis. Further standardization of models, protocols, and monitoring should further improve future animal therapy studies at least to the extent that it is possible to select particularly promising substances, which should then be tested in randomized controlled trials.

    Notes: Abstract We examined whether patients with both amyotrophic lateral sclerosis (ALS) and cancer differ from classical ALS patients, and whether motor neuron disease responds to oncological therapy. We analyzed clinical and immunological features of 14 patients (9 men, 5 women; mean age 65.3 years) with pure/definite ALS and cancer. Patients with solid tumor cancer and definite ALS were selected according to the El Escorial criteria; cases with ALS plus were excluded. Four patients had breast cancer, three lung adenocarcinoma, and three bowel tumor; hepatocarcinoma, kidney cancer, and mesothelioma were observed in one case each, and in one patient the primary tumor was unidentified. Patients' sera were examined for antinervous system antibodies by means of immunohistochemistry and western blot analysis. Of five patients who underwent surgical therapy, two worsened during the procedure, while the other three had no benefit. The remaining two patients did not improve after chemotherapy and radiotherapy. In none of our cases did the oncological disease progress. Death was a consequence of ALS in all eight patients who died. Median survival was 18 months and did not differ from that of 28 ALS patients matched for age, sex, and onset features (bulbar or spinal). Anti-nervous system antibodies were never detected. We conclude that our group of pure ALS patients with cancer do not significantly differ from patients with classical ALS. They usually die as a consequence of the motor neuron syndrome in the absence of cancer progression. To date we have not observed any response of ALS to antitumor therapy.

    Notes: Abstract To study the short-term effect of oral pulsed high-dose dexamethasone for myositis we treated eight newly diagnosed patients with three 28-day cycles of oral dexamethasone. Primary outcome measures were muscle strength, pain, and serum creatine kinase activity. Six patients responded. Side effects were mild. At follow-up five responders were still in remission, without ¶medication. Pulsed high-dose ¶dexamethasone seems beneficial in myositis. A larger, prednisone-controlled trial is justified to analyze long-term efficacy.

    Notes: Abstract Several recipient, donor and operation factors as well as postoperative complications related to patient survival after liver transplantation (LT) in children were studied by univariate and multivariate analyses . In a 13-year period, 103 patients under 15 years of age underwent 120 LT; the mean age was 63 months and 36 % were under 2 years of age. Indications for LT were cholestatic disease in 68 (56 %), metabolic diseases in 18 (14 %), fulminant hepatic failure in 8 (7.5 %), cirrhosis in 7 (5.8 %), and retransplants in 17 (14 %). Whole liver was transplanted in 79 % of cases and partial liver in 21 %. Actuarial survival at 1, 5, and 10 years was 70 %, 61 %, and 57 %, respectively. United Network of Organ Sharing (UNOS) I recipients (RR = 2.7), primary non-function (PNF) (RR = 13.9), and hepatic artery thombosis (HAT) (RR = 3.8) were independent factors for lower patient survival in multivariate analysis. Thus, in our experience, postoperative mortality as a consequence of the patient's condition before transplantation, or complications such as PNF or HAT, are the major causes of decreased survival in pediatric LT.

    Description / Table of Contents: Summary Background and objective: Primary cutaneous B-cell lymphomas (PCBCL) represent a unique type of extranodal B-cell lymphomas. Recently, the „European Organization for Research and Treatment of Cancer (EORTC)–Cutaneous Lymphoma Study Group” classified PCBCL into two major groups: one with low-grade malignancy and excellent prognosis (follicle center cell lymphoma, immunocytoma/marginal zone B-cell lymphoma) and the other with intermediate malignancy and worse prognosis (large B-cell lymphoma of the leg). The clinical course and the prognosis of both groups clearly distinguish them from nodal lymphomas with similar morphological aspects, thus underlying the need for different treatment modalities. Patients/Methods: We investigated retrospectively the therapeutic data from 51 patients with PCBCL (40 lowgrade lymphomas, 11 large B-cell lymphomas). Several treatment modalities were used: total excision, radiotherapy, polychemotherapy, systemic corticosteroids, systemic antibiotics, as well as a variety of combination treatments. Results: Recurrence, dissemination and/or death of the patients were not significantly related to any single treatment modality. Conclusions: In our opinion, the choice of treatment for PCBCL depends on the histologic classification, the number, spread and localization of the infiltrates, and on the general condition of the patient.
    Notes: Zusammenfassung Hintergrund und Fragestellung: Primäre kutane B-Zell-Lymphome (PKBZL) stellen eine eigenständige Krankheitsgruppe lymphoproliferativer Tumoren dar. In der vor kurzem von der „European Organization for Research and Treatment of Cancer (EORTC)-Cutaneous Lymphoma Study Group” publizierten Klassifikation kutaner Lymphome wurden 2 Hauptgruppen der PKBZL beschrieben: Eine mit niedriger Malignität und exzellenter Prognose (Keimzentrumslymphome, Immunozytom/„Marginalzonelymphom”) und eine 2. mit intermediärer Malignität und schlechterer Prognose (großzelliges B-Zell-Lymphom der unteren Extremitäten). Der Verlauf und die unterschiedlichen Prognosen weisen darauf hin, dass es notwendig ist, eine dem klinischen Verhalten entsprechende Therapieform zu wählen. Patienten/Methodik: Wir untersuchten die Verlaufsdaten von 51 Patienten mit PKBZL (40 niedrig maligne PKBZL und 11 großzellige PKBZL) retrospektiv. Als Behandlungsformen kamen Totalexzision, Strahlentherapie, systemische Kortison- und Antibiotikatherapie, Polychemotherapie sowie verschiedene Kombinationstherapien zur Anwendung. Ergebnisse: Das Auftreten von Rezidiven sowie von Lymphknoten- oder Organbeteiligungen stand in keinem signifikanten Zusammenhang mit der gewählten Therapiemodalität. Schlussfolgerungen: Aus der Vielzahl der verwendeten Behandlungsformen ist die Komplexität der Erkrankung an sich und die der Wahl der Therapie ersichtlich. Unserer Meinung nach sollte die Behandlung der PKBZL in Abhängigkeit von der histologischen Klassifikation, der Anzahl, Ausdehnung und Lokalisation der Hautinfiltrate sowie vom Allgemeinzustand des Patienten gewählt werden.

    Notes: Abstract Objective: This study was undertaken to determine the delay of extubation attributable to ventilator-associated pneumonia (VAP) in comparison to other complications and complexity of surgery after repair of congenital heart lesions in neonates and children.¶Methods: Cohort study in a pediatric intensive care unit of a tertiary referral center. All patients who had cardiac operations during a 22-month period and who survived surgery were eligible (n = 272, median age 1.3 years). Primary outcome was time to successful extubation. Primary variable of interest was VAP. Surgical procedures were classified according to complexity. Cox proportional hazards models were calculated to adjust for confounding. Potential confounders comprised other known risk factors for delayed extubation.¶Results: Median time to extubation was 3 days. VAP occurred in 26 patients (9.6 %). The rate of VAP was not associated with complexity of surgery (P = 0.22), or cardiopulmonary bypass (P = 0.23). The adjusted analysis revealed as further factors associated with delayed extubation: other respiratory complications (n = 28, chylothorax, airway stenosis, diaphragm paresis), prolonged inotropic support (n = 48, 17.6 %), and the need for secondary surgery (n = 51, 18.8 %; e. g., re-operation, secondary closure of thorax). Older age promoted early extubation. The median delay of extubation attributable to VAP was 3.7 days (hazards ratio HR = 0.29, 95 % CI 0.18–0.49), exceeding the effect size of secondary surgery (HR = 0.48) and other respiratory complications (HR = 0.50).¶Conclusion: VAP accounts for a major delay of extubation in pediatric cardiac surgery.

    Description / Table of Contents: Abstract For ACL lesions in children near to the end of the growth phase the treatment can be treated identical to that in adults. For younger children (8–12 years) the treatment must be conservative, combined with controls at short intervals. Behaviour during sport should be modified. If instability is experienced in activities of daily life or during sport a reconstruction of the ACL should be done using a central tibial transepiphyseal hamstring reconstruction with a femoral over-the-top position to avoid possible growth disturbances.
    Notes: Zusammenfassung Kreuzbandverletzungen bei Kindern, die nahe ihres Wachstumsabschlusses sind (14. bis 17. Lebensjahr) können wie Kreuzbandverletzungen von Erwachsenen behandelt werden. Kreuzbandverletzungen bei Kindern, die 13 Jahre und jünger sind, sollten zunächst abwartend behandelt werden (Kniebandage, Koordinationstraining, Belastungsreduzierung). Stellt sich im täglichen Leben oder bei sportlicher Belastung eine Instabilität im Sinne eines Giving way heraus, so sollte das Kreuzband rekonstruiert werden. Dabei ist es nach allen vorliegenden Daten unbedenklich, die Tibia zentral mit einem 8-mm-Bohrloch zu durchbohren und ein ligamentäres Transplantat durchzuziehen. Femoral ist es aus Sicherheitsgründen eher sinnvoll, statt einer transossären Bohrung die Over-the-top-Position zu wählen. Auch andere, rein epiphysäre Verankerungsmethoden (Semitendinosusplastik mit transossärer Drahtfixation) sind möglich.

    Description / Table of Contents: Abstract ‘Psychopathology after trauma’ mostly refers to cognitive or affective impairment after direct or indirect damage to brain tissue. Patients who have suffered a whiplash injury of the cervical spine, even without direct trauma to brain tissue, also often complain of cognitive or affective dysfunction for prolonged periods after the injury. Even more difficult to evaluate is psychopathology arising in the aftermath of severely distressing events, such as major disastrous accidents, natural catastrophes or assault. The medical expert must be aware of a variety of posttraumatic psychiatric disorders with different courses and symptoms and must be able to distinguish these from endogenous or merely coincident psychiatric disorders. In this paper, we outline the relevant diagnoses and diagnostic criteria, with special refrence to posttraumatic stress disorder (PTSD). It should be emphasized that while acute stress disorder is common after stressful experiences, PTSD is most likely to develop in the presence of personality traits or a concurrent psychiatric illness predisposing to the disorder. The nature of the trauma sustained is significant: for example, trauma inflicted by human aggression causes PTSD significantly more often than similar injuries suffered as the result of a motor vehicle accident. Finally, therapeutic strategies for posttraumatic disorders are briefly reviewed.
    Notes: Zusammenfassung Mit posttraumatischen psychischen Störungen sind in der Regel kognitive oder affektive Beeinträchtigungen in der Folge direkter oder indirekter Hirngewebeschäden gemeint. Aber auch Patienten mit Halswirbelsäulenschleudertrauma beklagen häufig und über lange Zeit kognitive oder affektive Störungen ohne Nachweis einer Hirnschädigung. Noch problematischer sind psychische Störungen in der Folge erheblich belastender Ereignisse, wie Unfälle katastrophalen Ausmaßes, Naturkatastrophen oder Überfällen, zu beurteilen. Dem ärztlichen Gutachter obliegt die Aufgabe, eine Reihe posttraumatischer Störungen, die sich hinsichtlich des Verlaufs und der Symptome unterscheiden, zu kennen und von anlagebedingten oder koinzidierenden psychischen Störungen zu differenzieren. In der vorliegenden Arbeit werden die relevanten Diagnosen ¶und diagnostischen Kriterien mit besonderer Behandlung der posttraumatischen Belastungsstörung (PTSD) besprochen. Hervorzuheben ist, dass es nach erheblich belastenden Erlebnissen recht häufig zu akuten Belastungsreaktionen kommt, während die PTSD in der Regel dann auftritt, wenn eine besondere persönliche Disposition oder psychiatrische Komorbidität vorliegen. Ferner kommt der Art des belastenden Erlebnisses Bedeutung zu. So wird eine PTSD häufiger nach Ausbrüchen menschlicher Aggression als nach z. B. Verkehrsunfällen gefunden. Abschließend wird ein kurzer Überblick über therapeutische Möglichkeiten bei posttraumatischen Störungen gegeben.

    Notes: Summary Background: Knowledge concerning the long-term antiretriviral and immunological efficacy of protease inhibitors in children is limited. Patients and Methods: An open-label, prospective, multicenter clinical trial was conducted over a period of 72 weeks in Switzerland. 60 HIV-1 infected children (aged 0.3–16.9 years) naive to protease inhibitors were enrolled. Ritonavir or nelfinavir and at least one new nucleoside reverse transcriptase inhibitor were introduced into the durrent treatment regimen. HIV-1 RNA levels and CD4 cell counts were monitored after introducing the protease inhibitor, and the tolerability and safety of the drugs were assessed. Results: Dictated by chronological availability, 37 children received ritonavir and 23 nelfinavir. At baseline, children given ritonavir had higher mean plasma HIV-1 RNA levels (5.03 vs 4.63 log10 copies/ml; p = 0.001) and lower mean CD4 cell counts (277 vs 555 cells/μl; p = 0.009) than children given nelfinavir. Antiretroviral treatment (ART) naive children showed higher mean plasma HIV-1 RNA levels than non-naive (5.18 vs 4.64 log10 copies/ml; p = 0.02). The decline in plasma HIV-1 RNA levels 72 weeks after treatment with ritonavir and nelfinavir was −2.17 and −1.30 log10 copies/ml, respectively (p = 0.006) and in ART-naive vs non-naive patietns −2.70 vs − 1.39 log10 copies/ml (p ≤ 0.01). 69% of ART-naive patients and 32% of non-naive patients achieved sustained plasma HIV-1 RNA levels 〈 400 copies/ml. Increases in CD4 cells were higher in ART naive compared to non-naive patients (p 〈 0.04). Conclusion: The antiretroviral and immunologic benefits of protease inhibitors are more profound in ART-naive than in non-naive children.

    Notes: Summary The aim of this prospective study was to compare epidemiological data and clinical features in children and adults with tick-borne encephalitis (TBE). Patients with aseptic meningitis diagnosed at the University Medical Centre, Department of Infectious Diseases, Ljubljana, Slovenia, from June to August 1997, in whom the diagnosis of TBE was ascertained by the presence of serum IgM antibodies against TBE virus, who were serologically negative for Borrelia burgdorferi sensu lato and had a negative PCR CSF result on enteroviral infection, were included in the study. Out of 213 patients with aseptic meningitis, 80 (37–56%) fulfilled inclusion criteria. There were 20 children and 60 adults. In both groups males predominated. Virtually all patients had headache and fever, and more than 50% suffered from vomiting. The majority of patients in both groups recalled a tick bite, had a biphasic course of the illness, and was found to have obviously expressed meningeal signs. In both groups the median CSF leukocyte count was somewhat lower than 100 × 106/l with a predominance of lymphocytes. Children were more often given antibiotics during the initial phase of TBE than adults (p = 0.0095). Several other statistically significant distinctions (p 〈 0.05) were found including the frequency of fatigue, malaise, vertigo, photophobia, myalgias, arthralgias, as well as elevated CSF albumin and protein concentration, elevated albumin quotient and IgG quotients; all these findings were more often present in adults. In addition a longer duration of fever, more frequent need for anti-edematous treatment and longer hospitalization were found in adults. Direct comparison of clinical and epidemiological characteristics of TBE in children and adults revealed differences in several clinical and laboratory features and corroborates the previous conclusion that TBE in childhood is a milder illness than TBE in adults.

    Notes: Abstract The purpose of this investigation was to ascertain the reasons given by mothers diagnosed with AIDS (acquired immunodeficiency syndrome) for disclosing or not disclosing their HIV (human immunodeficiency virus) status to their children, a dilemma faced by most HIV-infected parents and those who counsel them. We interviewed 29 mothers residing in one of two New York City facilities that provide housing and medical treatment for adults with AIDS. The majority of these mothers do not live with their children, but all had recent face-to-face contact with them. The two reasons most frequently considered important for disclosing to children were that disclosure was the “right thing to do” and the need to make arrangements for children's future in case of maternal death or incapacity. The reason most frequently considered important for not disclosing was maternal concern about discussing death and dying with children. These findings have significant implications for counseling of HIV-positive parents.

    Notes: Summary We prospectively followed 725 children under 2 years of age with laboratory-diagnosed Bordetella pertussis infection to investigate the hospitalization rate and complications. Diagnosis was made by culture and polymerase chain reaction (PCR) from nasopharyngeal swabs in 11,016 children who presented with ≥ 7 days of cough at 63 pediatric practices in Germany. Of these children, 33 (4.5%) were hospitalized at a mean age of 4.8 months (range, 17 days to 19.5 months). Complications occurred in 16 (48%) of the 33 patients. Pneumonia developed in two (6%) children and a convulsion was observed in one (3%). Intensive care monitoring was required for 23 (70%) children. Further complications were bradycardia (21%), apnea (12%), conjunctivitis (12%), loss of weight (12%), otitis media (6%), atelectasis (3%) and dehydration (3%). Children aged 6–24 months who had not received any dose of pertussis vaccine had a ten-fold increased risk of hospitalization compared to those who had been partially or fully immunized (p 〈 0.05). Pertussis immunization should be given at an early point in time and completely in order to prevent severe courses of pertussis and hospitalization in young children.

    Notes: Summary Background: Presently, most children with chronic osteomyelitis undergo surgery with the inherent risk of damage to their growth plate. We demonstrate a treatment regimen based on imaging procedures focussing on antibiotics in order to reduce the rate of surgical interventions. Patients and Methods: We retrospectively evaluated all 11 patients with clinically suspected chronic osteomyelitis who were treated at our institution from 1989 to 1995. Patients underwent open biopsy and surgical treatment only if imaging procedures showed signs indistinguishable from malignancy, or if they were highly suggestive for the presence of pus, joint infection or osteonecrosis. The patients were followed up for a minimum of 3 years. Results: All five patients treated solely with antibiotics recovered completely. Three patients were subjected to open biopsy and surgical treatment since they showed radiological signs indistinguishable from malignancy, and two patients due to pus or osteonecrosis. In follow-up, there was one relapse of chronic osteomyelitis 11 months after the first treatment course with surgery and antibiotics. One patient suffering from Ewing's sarcoma as detected by open biopsy was excluded. Conclusion: Our diagnostic procedure was useful to reduce the rate of surgery. Surgical treatment of chronic osteomyelitis is not always neccessary especially in cases of missing necrosis, joint infection and abscess as demonstrated by the complete recovery of our patients treated solely with antibiotics.

    Notes: Abstract The morpho-phonological nature of English orthography is examined in this study of the relation between morphological sensitivity and decoding ability in the latter elementary grades. Children in grades three to six were required to distinguish derivationally-related word pairs (e.g., nature-natural) from foil pairs that are related in spelling but not in morphology (e.g., ear-earth). The materials included both transparently-related (i.e., the second word incorporated the pronunciation of the first, as in person-personal) and complexly-related word pairs (i.e., the second word involved some change in pronunciation, as in atom-atomic). Across two experiments, these items were presented in either oral or written form along with various tests of reading ability, intelligence and phonological awareness. The results indicate that children's recognition of derivational relationships improved with grade-level. As anticipated, there was also a significant association between sensitivity to derivational relatedness and decoding ability which remains significant even when the word pairs were orally presented and even when phonological awareness in taken into account. Both phonological awareness and sensitivity to morphological structure emerge as important factors in decoding skill in the later elementary grades.

    Notes: Abstract  Hemangiopericytoma is a rare vascular tumor of pericyte origin with variable malignant potential. Very rarely, this tumor occurs as a primary bone lesion. We present a case of a highly malignant hemangiopericytoma of the proximal tibia. Current therapy consists of radical resection of the tumor with postoperative radiation therapy being recommended. Chemotherapy seems to be useful in disseminated disease. The prognosis correlates to the histological grading of the tumor. Early or late recurrence and distant metastases with fatal outcome, as shown in our case study, are not uncommon.

    Notes: Abstract  The concept of Sentinel Lymph Node Dissection (SLND) has strongly influenced the surgical approach towards primary melanoma in the last decade. Initiated by the disappointing results of elective lymph node dissection (ELND) in this malignancy, the concept of analyzing the first draining lymph node (Sentinel) of a regional basin was developed as a diagnostic means to avoid unnecessary ELND in case of negative SLNs. According to recent standards detection of the SLN should be performed by a triple approach: injection of 90 nm Technetium and patent blue in the periphery of the primary melanoma, and intraoperative tracing of radioactivity with the aid of a hand-held gamma probe. Histopathological examination of alternating series sections of the whole lymph node appears to be the best analytic approach. Molecular biologic procedures such as tyrosinase RT-PCR are time-consuming to perform and produce contradictory results. SLND for cutaneous melanoma is an interdisciplinary diagnostic approach involving surgery, dermatology, pathology, and nuclear medicine. In spite of a variety of published promising results derived from clinical trials ranging from a few dozens to several hundred included patients the diagnostic and prognostic value of SLND remains to be confirmed by ongoing controlled prospective clinical trials. At this stage, SLND can by no means be considered a therapeutic procedure. These aspects have to be kept in mind when informed consent is obtained from patients as well as in the individual determination of the risk-benefit ratio.

    Notes: Abstract To evaluate the effectiveness in decreasing recurrence of cast application after manual reduction of pulled elbow. Sixty-four children with pulled elbow were randomized into two treatment groups: Group A underwent manipulative reduction followed by splinting the elbow in a flexed and supinated position for 2 days; group B underwent manipulative reduction only. Both groups were examined 2, 5, and 10 days later. None of the 33 patients in group A had a pulled elbow at follow-up. Four (13%) of 31 patients in group B had a pulled elbow 2–5 days later. Immobilizing the elbow for 2 days after manipulative reduction improves the success of treatment of a pulled elbow.

    Notes: Abstract  The authors studied the role of the sole posterior fossa bony decompression in the management of symptomatic children affected by Chiari type I anomalies. The series in the pediatric literature on this subject were reviewed and compared with that presented in this article. From May 1994 to December 1998, 53 patients (3 months to 26 years) were observed. They were divided into: asymptomatic patients (27), who received no surgical treatment and were only subject to clinical observation; symptomatic patients (brain stem compression 16, syringomyelia 10, including 7 with holocord). All the symptomatic patients were treated with the same surgical approach: bony decompression of posterior fossa with removal of the posterior arch of C-1 and the outer layer of the dura without dural opening. In all 16 (100%) of the 16 patients with brain stem compression the symptoms resolved or improved; in patients with syringomyelia the symptoms were resolved or improved in 94.4% of cases. Two children required further surgery after 13 and 24 months, respectively.This series seems to demonstrate that even a simple extradural surgical approach, with a lower rate of postoperative complications and short stay in hospital, is sufficient to arrest the disease and to improve the symptomatology in a high percentage of cases (97.2%), which is comparable to that achieved with other, more aggressive, procedures.

    Notes: Abstract  Electrophysiological studies of a child with presumed botulism showed that the amplitude of the serially and electrically elicited blink reflexes Rl, R2 and R2’ was reduced during recovery. These findings suggest a conduction block of the facial nerves. Other nerve conduction studies and an incremental response to repetitive stimulation demonstrated a block of the presynaptic neuromuscular transmission. Results of the biological tests were negative, but those of electrodiagnosis and clinical examination favored a diagnosis of botulism. A combination of electrically elicited blink reflexes and rapid repetitive stimulation of the peripheral nerves was found to be a sensitive method of assessing the integrity of neuromuscular junctions and the subclinical impairment of muscle nerves.

    Notes: Abstract  In order to analyze the surgical outcome according to clinical characteristics and to evaluate the correlation between clinical improvement and neuroimaging changes, we retrospectively reviewed 32 children who had undergone endoscopic III ventriculostomy (ETV) from February 1994 to May 1998. There were 15 boys and 17 girls, with a mean age of 5.2 years (range: 1 month to 13 years). The etiology of the hydrocephalus was primary aqueductal stenosis in 18 patients, secondary aqueductal stenosis caused by tumors in 5, IV ventricle outlet obstruction in 5, and hydrocephalus associated with meningomyelocele in 4. The mean duration of follow-up was 19.4 months (range 1–50 months). Overall, surgical outcome was regarded as good in 21 of 29 patients. Surgical outcome was poor in patients younger than 1 year (P〈0.05). Neuroimaging 1 month after ETV showed a decrease in ventricular size in 11 of the 16 patients with good surgical outcomes. Five showed minimal changes only. In patients with good outcomes, ventricular size tended to decrease as time passed. Resolution of periventricular edema, flow void in the III ventricle on T2-weighted axial images, and cine-MR imaging were sensitive indicators of good outcome. We suggest that ETV be considered as a primary treatment option in patients older than 1 year of age with noncommunicating hydrocephalus. In addition, time factors should be taken into consideration when surgical outcome is judged. Changes in ventricular size could not predict surgical outcome completely in themselves. Therefore, a comprehensive postoperative assessment should be made with the help of T2-weighted MRI and cine-MRI.

We treated a 20-year-old male patient who underwent three arthroscopies, one operation and one MRI; finally, phlebography detected a popliteal vein aneurysm and a malformation of the deep venous system of the popliteal and proximal calf veins. To avoid the threat of pulmonary embolism a resection of the aneurysm with interposition of a venous autograft was performed. Twelve months after the operation the patient is free of symptoms with a patent autograft.
    Notes: Zusammenfassung  Eine seltene Ursache schmerzhafter Schwellungen in der Kniekehle kann ein Aneurysma der V. poplitea sein. Bisher wurden 28 Fälle dieser Fehlbildung in der Weltliteratur beschrieben. Wir sahen einen 20-jährigen männlichen Patienten, bei dem nach 3 Arthroskopien, einer Arthrotomie und einer MRT durch eine Phlebographie ein venöses Aneurysma der V. poplitea mit venös-aneurysmatischer Malformation der proximalen Unterschenkelvenen festgestellt wurde. Um eine potentiell tödliche Lungenembolie zu vermeiden, erfolgte die Resektion mit Interposition der kontralateralen gedoppelten V. saphena magna. 12 Monate nach der Operation hat der Patient bei duplexsonographisch gutem Flow im Interponat keine Beschwerden.

    Description / Table of Contents: Summary Surgery is still the primary therapeutic approach in treatment of tumors in the head and neck area, dating back to the early nineteenth century. More than 150 years ago, hemimaxillectomies and mandibular resections as well as hemiglossectomies were already performed by leading surgeons. The block principle we are now following dates back to Crile, who also established the principle of cervical lymph node dissection. Ablative oncologic surgery has always been closely linked with plastic and reconstructive surgery, rendering radical surgical interventions possible without disfiguring patients. The development of facial reconstructive surgery proceeded in stages, in the first instance as secondary reconstruction using tube pedicled flaps. The change to the concept of primary reconstruction occurred via arterialized skin flaps and myocutaneous flaps to the widely accepted and performed free tissue transfer. Free bone grafting, inaugurated earlier and still representing the majority of bone grafting, has been supplemented for certain reconstructive purposes by free vascularized bone transfer from various donor sites. Although the five-year-survival rate of carcinoma of the oral cavity has remained unchanged in the past 30 years, distinctive improvements in tumor surgery can be recorded. This is primarily based on improved diagnostics such as modern imaging techniques and the refinement of surgical techniques. The DÖSAK has worked out distinctive guidelines for effective ablative oncologic surgery. Surgical approaches offering wide exposure and carrying low morbidity play a decisive role in radical resections. For this reason, midfacial degloving offers an essential improvement for the resection of midface tumors, especially from an aesthetic point of view. Tumors situated deep behind the viscerocranium at the skull base can be clearly exposed either through a lateral approach following a temporary osteotomy of the mandibular ramus or a transmandibular, transmaxillar, or transfacial approach with minimal morbidity. Concerning the concept of neck dissection, radical techniques are more and more abandoned in favor of a more conservative procedure. Actual inquiries concerning present surgical procedures as to the surgical strategy in “No-neck” or marginal and segmental resection in mandibular adherent carcinomas demand scientific clarification.
    Notes: Zusammenfassung Im Zentrum der Behandlung von Tumoren im Kopf-Hals-Bereich steht immer noch die Chirurgie, deren Ansätze weit in das 19. Jahrhundert zurückreichen. Schon vor weit über 150 Jahren wurden durch wegweisende Chirurgen Halbseitenresektionen des Ober- und Unterkiefers sowie der Zunge durchgeführt. Das heute von uns verfolgte Blockprinzip geht auf Crile zurück, der auch die Prinzipien der Halslymphknotenausräumung festschrieb. Eng verknüpft mit der Tumorchirurgie war stets die plastische und rekonstruktive Chirurgie, die radikalchirurgische Eingriffe ohne Entstellung der Patienten erst ermöglichte. Die Entwicklung der wiederherstellenden Gesichtschirurgie verlief in Phasen, zunächst als sekundäre Rekonstruktion mittels Rundstiellappen. Der Wandel zur primären Wiederherstellung vollzog sich über arterialisierte Hautfettlappen und die Myokutanlappen bis zum heute aktuellen mikrovaskulär anastomosierten Gewebetransfer. Die schon früh inaugurierte und heute noch praktizierte freie Knochentransplantation wurde für spezielle Indikationen durch den mikrochirurgischen Knochentransfer aus verschiedenen Spenderregionen ergänzt. Obwohl die 5-Jahres-Überlebensraten für das Mundhöhlenkarzinom in den letzten ¶30 Jahren stagnieren, sind heute doch deutliche Fortschritte in der Tumorchirurgie zu verzeichnen. Diese beruhen zunächst auf einer verbesserten Diagnostik durch die modernen bildgebenden Verfahren und die Weiterentwicklung der Operationsverfahren. Für eine erfolgreiche Tumorchirurgie hat der DÖSAK klare Richtlinien erarbeitet. Für eine radikale Tumorresektion spielen übersichtliche und wenig destruierende Zugangswege eine entscheidende Rolle. So brachte für die Tumoren des Oberkiefers das Midfacial degloving eine wesentliche Verbesserung, insbesondere auch aus ästhetischer Sicht. Versteckt hinter dem Gesichtsschädel liegende Tumoren an der Schädelbasis lassen sich entweder über einen lateralen Zugang nach temporärer Osteotomie des Unterkieferasts oder transmandibulär, transmaxillär oder transfazial übersichtlich ohne Destruktionen darstellen. Bezüglich der Halslymphknotenausräumung ist eine Abkehr vom radikalen zum konservativen Vorgehen zu verzeichnen. Derzeit aktuelle chirurgische Fragen, wie das operative Vorgehen beim „N 0 -Hals“ oder Kastenresektion bzw. Kontinuitätsresektion des Unterkiefers bei der Mandibula adhärenten Karzinomen, bedürfen einer wissenschaftlichen Klärung.

    Description / Table of Contents: Summary Malignant melanoma is one of the most frequent malignancies of the skin. This is particularly true of malignant melanoma in juveniles. Its incidence has more than doubled from the 1970s to the mid-1990s. Presently, 15 new cases are recorded per 100,000 inhabitants a year in Germany. At Fachklinik Hornheide, a tumor center specializing in skin neoplasm with patients being referred from all over Germany, the number of melanoma patients treated per year has been approximately 500–¶550 for the past 10 years. In the present study, the state-of-the-art therapy for primary melanoma and treatment of the regional lymph node system is discussed. The radical treatment formerly advocated with wide tumor resection plus radical neck dissection is no longer justified for this immunogenic malignant tumor caused by endogenic as well as exogenic factors. “Sentinel lymph node” imaging by means of radioactive substances for diagnosing possible melanoma metastases in adjacent lymph nodes has changed the therapeutical concept. Tumor staging by means of ultrasound, CT, MRT, or PET allows the differentiation of tumors without distant metastases and a favorable prognosis, from melanomas which have to be considered as generalized disease. In addition to surgical resection of the tumor and neck dissection for removal of lymph nodes, adjuvant immunotherapy with interferon-α is capable of prolonging survival without a recurrence. Palliative chemotherapy or immunotherapy are valuable options for cases with generalized melanoma. Vaccination with a melanoma-associated antigen or dendritic cells is at an experimental stage and may become part of future treatment strategies.
    Notes: Zusammenfassung Das maligne Melanom gehört, insbesondere in jugendlichen Altersgruppen, zu den häufigsten malignen Tumoren der Haut. Seine Inzidenz hat sich von den 70er Jahren bis zur Mitte der 90er mit etwa 15 Fällen/¶100.000 Einwohnern und Jahr mehr als verdoppelt. In der Fachklinik Hornheide, einer Tumorklinik der Haut mit bundesweiten Zuweisungen, hat sich dagegen im letzten Jahrzehnt die Zahl der behandelten Patienten auf etwa 500–550 Fälle pro Jahr stabilisiert. Die vorliegende Arbeit soll den aktuellen Standard der Therapie der Primärtumoren und der regionären Lymphabflussregion darstellen. Dabei soll vermittelt werden, dass das frühere radikale Behandlungskonzept mit großflächigen lokalen Tumorresektionen und einer radikalen Ausräumung aller Lymphknotenstationen des Halses diesem immunogenen bösartigen Tumor, dessen Entwicklung teils endogenen und teils exogenen Faktoren unterliegt, nicht mehr gerechtfertigt ist. Schon im Bereich der Diagnostik der fraglichen lymphogenen Metastasierung des Melanoms hat die Darstellung des „sentinel-lymph-node“ mit radioaktivem Material eine Änderung des Therapiekonzepts erzwungen. Das Tumorstaging mit Hilfe der Sonographie, der CT-, der MRT- und PET-Untersuchungen vermag prognostisch günstige Tumoren ohne Nachweis von Fernmetastasen von solchen Melanomen zu unterscheiden, die als generalisierte Erkrankung zu bewerten sind. Neben der operativen Entfernung des Tumors und der Ausräumung der Lymphknotenstationen des Halses ist in bestimmten Stadien die adjuvante Immuntherapie mit Interferon α geeignet, das rezidivfreie Überleben zu verlängern. Bei einer Generalisierung besteht die Option einer palliativen Chemo- oder Immunochemotherapie. Experimentelle Behandlungsansätze überprüfen den Einsatz von Vakzinierungsstrategien mit melanomassoziierten Antigenen und dendritischen Zellen.

    Notes: Abstract No recent update is available on long-term results of the various types of treatment of obstructive sleep apnea (OSA) which can help the physician in evaluating the individually tailored treatment for patients with OSA in the long term. We arbitrarily defined “long-term” results as those after at least 3 years and reviewed the literature from the past 25 years for reports on conservative, apparative, and surgical therapy of OSA in children and adults. Another inclusion criterion was that the diagnosis was also confirmed by polysomnography before treatment and at follow-up. Only relatively few long-term studies meeting the criteria of ‘evidence based medicine’ were found, comparing the findings of these was difficult or impossible due to varying criteria for success. Long-term data were available about the effect of weight reduction, nasal ventilation therapy, oral devices, tonsillectomy, uvulopalatopharyngoplasty, maxillomandibular advancement osteotomies, and tracheotomy. After approx. 25 years many treatment modalities in sleep medicine are still experimental concerning the long-term use for the individual. In particular, randomized controlled trials in surgery are lacking. Late results show that at least 50% of patients with OSA can be treated effectively by one or a combination of treatments. Nasal continuous positive airway pressure, tracheotomy, maxillomandibular advancement osteotomy, and tonsillectomy are the most effective treatments of OSA.

    Notes: Abstract This study aimed to assess the quality of life of a population sample of schoolchildren. The Generic Children's Quality of Life Measure (GCQ) has been developed to allow comparison between chronically ill children and the general child population. The measure assesses how the child views his or her life and also how they would like it to be. Quality of life is measured as the discrepancy between the two viewpoints. This large community-based survey aimed to establish GCQ norm values for children aged 6–14 years. The children were from a sample of schools stratified by geographical location and social need: rural affluent, rural low affluence, urban affluent and urban low affluence. 720 completed questionnaires were analysed. The scores were normally distributed with a wide range. The GCQ showed an acceptable reliability with a Cronbach's α of 0.75. The quality of life score was not correlated with age (r = −0.02, p = 0.64) nor with the deprivation score of the area in which the children lived (r = −0.026, p = 0.49). There were no significant differences between the scores by gender (p = 0.22) nor by rural/urban location (p = 0.60). Normative values were established. The GCQ is suitable for using with children over a large age range (6–14 years) without the scores being confounded by the age, gender, affluence or geographical location.

    Notes: Abstract We analysed the inter-relationships of the cause and the type of trauma, the presence of pelvic fracture, the associated intraabdominal organ injuries,and the morbidity and mortality rates in 154 patients presenting and being treated for UGT between 1983 and 1997.The cause of injury was blunt in 77% of cases and penetrating in 13%. The most frequently injured organs were kidney followed by urethra and bladder. Bowels, liver and spleen were the most frequently associated injured organs. Moreover, bladder injuries were strongly associated with bowel injuries (p 〈 0.0001). Hemodynamically normal 49 children with minor or major kidney injuries were managed conservatively. Hemodynamically non-stable 11 patients were explored.The majority of urogenital injuries can be managed conservatively evenwhen associated with intraabdominal organ injuries. Solid genitourinary organ injuries may accompany more frequently to intraperitoneal solidorgan injury. Whereas, non-solid genitourinary organ injuries may more frequently associated with injuries of intraperitoneal hollow viscus.

    Notes: Abstract This study compared the health-related quality of life (HRQL) of 236 children with mild or moderate/severe asthma with that of a large representative sample of children in the general community. The study also examined the relationship between the HRQL of children with asthma and their demographic characteristics, asthma severity and family functioning. Children with asthma had a significantly poorer HRQL than other children in the community. Amongst the children with asthma, parents reported that children living in single-parent families had poorer physical health, mental health and social functioning than children in two-parent families. There was a significant relationship between the mental health of children with asthma and family functioning but no significant relationship between their physical health and family functioning. These findings suggest that the domains comprising the HRQL of children with asthma are related to both disease and non-disease factors. A better understanding of these relationships will facilitate the development of new interventions to help children with asthma.

    Notes: Abstract Children of incarcerated parents are five to six times more likely to go to prison than their peers (Johnston, 1995). Yet, there is a lacuna in the literature that examines the effectiveness of interventions for children with an incarcerated family member. The purpose of the present study is to describe a solution-focused, mutual aid group intervention and to examine the effects of the group on the self-esteem of elementary-age Hispanic children of incarcerated parents when compared to a no-treatment comparison group. Implications for social work practice and research with this vulnerable population are addressed.

    Notes: Abstract Working memory capacity is described as a pool of limited resources that carry out processing and storage functions. Its role has been emphasised in adults' reading comprehension. The present study had two aims: First, to study the relationship between working memory capacity and reading comprehension in fourth-grade children. Second, to study the nature of the working memory resources involved in reading comprehension, i.e., are they specific or general?To test the first point, the predictive power of working memory capacity was compared with two reading-related basic skills, vocabulary and decoding skills. To test the second point, different working memory tasks were devised using verbal, numerical and spatial materials. All the tasks were administered to 48 fourth-grade children. The results showed that working memory capacity was a direct predictor of reading comprehension when contrasted with vocabulary and decoding skills. Moreover, it seemed that working memory would be better described as a system specialised for the processing of symbolic information in that only the verbal and in a lesser extent the numerical working memory tasks were significant predictors of reading comprehension. The spatial task did not correlate with reading comprehension. The reasons accounting for the predictive power of working memory tasks were discussed.

    Description / Table of Contents: Abstract Hypertensive crisis is defined as an extreme elevation of arterial blood pressure, with diastolic pressure 〉 120 mm Hg, and represents an imminent risk to the patient. In such cases, a rapid orientating diagnosis and adequate antihypertensive treatment to avoid sequelae are needed, sometimes even before diagnostic test are completed. Hypertensive emergencies and hypertensive urgencies can be distinguished. If the critical increase in blood pressure is associated with end-organ damage such as encephalopathy, acute left heart failure and pulmonary edema, angina pectoris, myocardial infarction or dissecting aortic aneurysm, a hypertensive emergency is presnet, that is an acute threat to the patient's life. A hypertensive emergency requires effective lowering of blood pressure within minutes, but not necessarily to normal range. The choice of suitable antihypertensive agents depends on clinical symptoms, contraindications, duration of pressure elevation and underlying conditions, prior cardiovascular, cerebrovascular and renal disorders. The risk of imminent end-organ damage must be weighed against the risk of rapid blood pressure lowering. In hypertensive urgencies without end-organ complications, blood pressure can be lowered more slowly over several hours, often with oral agents to avoid detrimental fall in blood pressure. The drugs of choice are mainly urapidil IV and nitroglycerine.
    Notes: Zusammenfassung Die hypertensive Krise stellt mit ihren kardialen, zerebralen und renalen Folgeerscheinungen eine potentiell lebensbedrohliche Komplikation der arteriellen Hypertonie dar. Bei einem hypertensiven Notfall (emergency), der den Patienten vital gefährdet, geht der kritische Blutdruckanstieg mit Organschä,den wie der Enzephalopathie, einer akuten Linksherzinsuffizienz, Angina pectoris, Herzinfarkt oder einem dissezierenden Aortenaneurysma einher. Der hypertensive Notfall erfordert eine umgehende effektive Blutdrucksenkung innerhalb von Minuten. Liegt eine Dringlichkeit (urgency) vor, bei der die oben genannten Folgeerscheinungen und Symptome bei stark erhöhten Blutdruckwerten fehlen, reicht eine langsame Absenkung des arteriellen Blutdrucks über mehrerer Stunden aus. Die Auswirkung der Hypertonie auf die Zielorganfunktion muß gegen das Risiko einer exzessiven Blutdrucksenkung abgewogen werden. Das Ausmaß der notwendigen Drucksenkung sowie die Wahl des geeigneten Antihypertensivums werden durch die klinische Symptomatik, Kontraindikationen, Dauer und Ausmaß der Blutdrucksteigerung und die zugrundeliegenden Vorerkrankungen des Patienten bestimmt. Eine zu langsame, aber auch eine zu rasche Blutdrucksenkung können zu schwerwiegenden Folgeschäden führen. Bei einer hypertensiven Dringlichkeit ohne Endorgankomplikationen ist meist eine allmähliche Blutdrucksenkung mir oral verabreichten Antihypertensiva ausreichend. Mittel der Wahl sind Urapidil intravenös und Nitroglycerin.
