    Description / Table of Contents: Zusammenfassung Durch elektronenmikroskopische Untersuchungen an 8 Fällen menschlicher akuter Nierenversagen konnten die aus tierexperimentellen Beobachtungen bekannten ultrastrukturellen Veränderungen am Nephron auch für das menschliche akute Nierenversagen bestätigt werden. Die Untersuchungen erfolgten unter besonderer Berücksichtigung der Einzelzellveränderungen, insbesondere der proximalen Tubuluszellen. Herausgestellt wurden die aus der Einzelzellschädigung resultierenden Veränderungen im Bereich der renalen Flüssigkeitskompartimente. Die ultrastrukturellen Veränderungen der Tubuluszellen beim akuten Nierenversagen deuten auf eine gravierende Beeinträchtigung der zellulären Transportkapazität für Elektrolyte und metabolischer Prozesse hin. Die durch Tubuluszellnekrosen oder durch Lösung von Gap- bzw. Tight-Junctions entstehenden Shunt-Wege zwischen tubulärem Flüssigkeitskompartiment und funktionellem Interstitium werden in ihrer Bedeutung für die gerichteten aktiven Transportvorgänge der Tubuluszellen für Natriumchlorid und den passiven Wasserstrom diskutiert. Die morphologischen Befunde werden unter besonderer Berücksichtigung neuer Ergebnisse der zellulären Membranprozesse und des Elektrolyttransportes besprochen. Eine Reinterpretation morphologischer und funktioneller Befunde beim akuten Nierenversagen unter besonderer Berücksichtigung der Einzelzellfunktion und der Integrität der renalen Flüssigkeitskompartimente wird vorgeschlagen.
    Notes: Summary The ultrastructural alterations at the nephron established in animal experiments, were also confirmed, by means of an electron-microscopic examination, in eight cases of human acute renal failure (ARF). Special consideration was given in this study to single cell alterations, particularly in proximal tubular cells, with emphasis being placed on alterations due to single cell damage in the region of the renal fluid compartments. The ultrastructural alterations of the tubular cells in ARF, suggest serious impairment of the cellular capacity for electrolyte transport and metabolic processes. The shunt paths between the tubular fluid compartment and the functional interstitium, arising from necrosis of the tubular cells or dissolution of the gap or tight junctions, were discussed in terms of their significance for the directional, active transport processes of the tubular cells for sodium chloride and the passive water flow. The morphologic findings were reviewed in light of recent findings on cellular membrane processes and electrolyte transport. A reinterpretation of the morphologic and functional findings in ARF is suggested. This takes into consideration single cell function and the integrity of the renal fluid compartments.

    Notes: Abstract An unusual case ofChlamydia trachomatis (C. trachomatis) pneumonia, complicated by the development of a pneumothorax, is reported in an IgG2/IgG4 deficient infant delivered by caesarean section.C. trachomatis was isolated initially from a throat smear and subsequently from pleural effusions. Serological examinations using the complement fixation test were negative in sera of both mother and child. However, using immunofluorescence the presence of an acute or recent infection was confirmed by IgM-antibodies in the serum of the infant and IgA-antibodies in the serum of the mother. At the age of 7 months the girl suffered from impetigo contagiosa which was partially resistant to antibiotic treatment. IgG-subclass deficiency was diagnosed after the onset of this disease and the girl was then treated by immunoglobulin transfusion.

    Notes: Twenty-four joints (10 knees and 14 ankles), with at least one manifestation of bleeding (proven by sonographic assessment), of 15 patients with haemophilia were investigated prospectively. For magnetic resonance imaging (MRI) evaluation, the MRI scale of Nuss et al. was modified to a MRI score (max. 13 points/joint) to allow a comparison with the physical examination score (max. 12 points) and the radiological score (Pettersson score; max. 13 points). The number of joint bleeds correlated well with the degree of arthropathy P 〈 0.01). In all 16 joints with a maximum of two bleeds, no alterations were found by physical examination, or radiological and MRI assessment. Joints with three bleeds had physical examination scores between 0 and 2, Pettersson scores from 0 to 3 and MRI scores of 2. Joints with four or more bleeds had physical examination scores ranging between 3 and 7, radiological scores between 7 and 12 and MRI scores between 3 and 8. The MRI score describes initial joint alterations more precisely and earlier than other assessments, allowing a discerning estimation of the degree of arthropathy, as well as a follow-up of haemophilic arthropathy and an improvement after change of treatment. In addition, the modified MRI score seems to differentiate better between early and advanced signs of arthropathy than the MRI scale of Nuss et al.

    Description / Table of Contents: Zusammenfassung Wir berichten über einen 11 Monate alten männlichen Säugling, der als Neugeborener BCG-geimpft worden war. Im Alter von neun Monaten entwickelte sich ein umschriebener, unbeweglicher Brustwandtumor über der rechten Mamille. Der Tumor zerstörte die vierte Rippe und infiltrierte die umgebenden Weichteile. Auf Grund des Röntgenbildes und des CT-Befundes wurde ein Malignom vermutet. Histologisch zeigte sich jedoch das typische Bild einer Tuberkulose, undMycobacterium bovis (BCG-Stamm) wurde aus dem Operationsmaterial angezüchtet. Als Ursache des Tumors fand sich somit eine ungewöhnliche Form von Rippen-BCG-Osteomyelitis, die mit einem negativen Befund im Knochen-Szintigramm einherging.
    Notes: Summary We present the case of an 11-month-old male infant who had been BCG vaccinated as a neonate. At the age of nine months, he developed a localized tumor above his right mamilla. The tumor destroyed the fourth rib and infiltrated the surrounding soft tissue. X-ray and CT scan suggested a malignant neoplasm. Histology, however, showed the typical picture of tuberculosis andMycobacterium bovis (BCG strain) was isolated from the lesion. Thus, the tumor was caused by an unusual presentation of a costal BCG osteomyelitis which was associated with negative findings in the bone scan.

    Notes: Abstract Intraspinal high-grade astrocytoma in children is an extremely rare tumor entity with disappointingly short survival times despite multimodality treatment. We report on a girl with anaplastic astrocytoma at level T9–11, who was treated with tumor resection, multidrug chemotherapy and irradiation. Local recurrence was diagnosed after 16 months. With reference to other cases reported in the literature, the course of disease, achievements and limitations of currently available therapeutic options, and potential future strategies are discussed.

    Notes: Abstract A 1-year-old child with an aneurysmal bone cyst in the scapula is presented. The sonographic examination showed a cystic formation with intraosseal fluid levels that shifted after repositioning of the child. Similar findings have been reported on CT scans and it is suggested that shifting fluid levels are an indicative feature of aneurysmal bone cyst.

    Notes: Abstract  Limited data exist on therapeutic options for established hepatic veno-occlusive disease (VOD) in pediatric patients after stem cell transplantation (SCT). In this report, we present data on the successful treatment of VOD in three children following allogeneic SCT and report the duplex ultrasound criteria for the confirmation of the diagnosis and for the evaluation of the treatment progress. All patients were 〈2 years at the time of transplantation and had received preparative regimens containing busulfan and cyclophosphamide. There were no known pretransplant risk factors for VOD. Allogeneic stem cell transplantation was performed from a sibling donor for CMML and from unrelated donors for Wiskott-Aldrich syndrome and familial hemophagocytic lymphohistiocytosis (FHL). The onset of first clinical symptoms of VOD (as defined by the Seattle and Baltimore criteria) was relatively late in all three patients (days +19, + 20, and +25, respectively). Time from onset of first symptoms until confirmation of diagnosis by serial duplex ultrasound examination was 4–11 days. Duplex ultrasound criteria are as follows: complete change of direction of blood flow in the portal vein, decrease of flow in the hepatic veins, and development of collateral circulation. Treatment was initiated upon confirmation of VOD by continuous infusion of prostaglandin E1 (initial dose 0.075 μg/kg/h) in addition to low-dose heparin (100 units/kg/d). Treatment was continued at the maximum tolerated dose of 0.3–0.5 μg/kg/h of PGE1. After 9, 14, and 25 days of treatment respectively, normal portal vein flow was restored and treatment could be discontinued. All three patients are alive and well without apparent sequelae.
