    Notes: Summary HCMV infection diagnosed by the highly sensitive polymerase chain reaction (PCR) technology in blood, urine and skin biopsies of patients after bone marrow transplantation (BMT) correlated with the reconstitution of peripheral blood lymphocytes and dermal immunohistological alterations to evaluate the interaction of viral infection with the recovery of the immune system, as well as with the induction or aggravation of graftversus-host disease (GVHD). In a prospective study 73% of 63 patients showed viremia at a median time of 25 days after BMT. Only 44% of these cases that also presented with a higher frequency of acute GVHD symptoms developed HCMB disease later on. In the skin, similar immunohistological alternations, as well as frequent primary local HCMV infection before the development of cutaneous signs of GVHD, was found, suggesting the direct involvement of anti-HCMV immune responses in the induction of GVHD-associated organ lesions.

    Notes: Summary Skin biopsies of 26 patients with leukemia and seven patients with aplastic anemia were investigated before and at different stages after allogeneic bone marrow transplantation (BMT) to establish the immunological criteria which distinguish skin alterations during normal reconstitution from dermal lesions mediated by graft-versushost disease (GvHD). Of the 33 patients studied 27 presented with clinically diagnosed acute and/or chronic GvHD, one patient died of bone marrow rejection. Immunohistological analysis of the respective skin biopsies with selected monoclonal antibodies against human leukocyte antigens (HLA) and differentiation antigens of the lympho-hematopoietic cells revealed low dermal mononuclear cell counts with phenotypically normal constituents in five cases with uncomplicated reconstitution post-grafting. In contrast, increased dermal cellular infiltrates predominantly consisting of Lyt 3+, OKT 8+ T-lymphocytes, as well as of a large number of Ia-like (immune response associated = HLA-D) determinant+ monocytes/macrophages were observed in all patients with active acute/chronic GvH reactivity. As sign of activation simultaneous expression of HLA-D region products was also found on a subset of the invading OKT 8+ T-lymphocytes. Progression of GvHD was associated with additional surface staining of keratinocytes for Ia-like determinants. Loss of Ia-like determinant+, OKT 6+ dentritic epithelial cells in all leukemic patients, as well as in patients with aplastic anemia with or without GvHD suggested damage of Langerhans cells due to the previous radiotherapy and/or specific immunological destruction. In patients with fatal outcome of GvHD prolonged reduction of these dentritic epithelial cells seemed to be indicative of impaired immune reconstitution or bone marrow dysfunction. Thus immunopathological features of skin GvHR may enable early recognition and prognostic evaluation of this disease possibly allowing more effective therapy.

    Description / Table of Contents: Abstract Seeing as gamma-hydroxybutyrate (GHB) and benzodiazepines interact with the GABA-transmitter system, we investigated whether GHB can replace the conventional therapy, which uses benzodiazepines in the treatment of alcohol withdrawal syndrome in ICU settings. Methods: 42 chronic alcoholics were included in this prospective and randomized study. Folllowing the development of alcohol withdrawal syndrome, the patients were randomly allocated to the GHB or to the flunitrazepam group. In addition to this, clonidine was administered in order to treat autonomic signs of withdrawal. In cases were hallucinations occurred, haloperidol was administered. Results: There was no significant difference in the efficacy of treatment used in the duration of mechanical ventilation and intensive care unit stay between groups. The patients in the GHB-group required significantly higher dosages of haloperidol and significantly lower dosages of clonidine. 14 out of 21 patients from the GHB-group developed hypernatriaemia and 15 out of 21 developed a metabolic alkalosis. Conclusions: Symptoms of the autonomic nervous system were more effectively prevented by GHB as evident in the lower dosage requirement of clonidine. However, GHB may not sufficiently block the hyperactivity of the dopaminergic system or may have an hallucinogenic effect itself. This may be evident from the higher dosages of haloperidol which were necessary. Due to the latter fact, the administration of GHB cannot be recommended in all patients suffering from AWS in ICU settings.
    Notes: Zusammenfassung Gamma-Hydroxybuttersäure (GHB) und Benzodiazepine interagieren beide mit dem gabaergen Transmittersystem. Vergleichend wurden sie zur intravenösen Therapie des Alkoholentzugssyndroms bei Patienten einer interdisziplinären operativen Intensivstation eingesetzt. Methodik: 42 alkoholabhängige Patienten, die ein Alkoholentzugssyndrom entwickelten, wurden randomisiert entweder mit GHB oder Flunitrazepam behandelt. Additiv erhielten sie symptomorientiert Clonidin oder Haloperidol. Ergebnis: Zwischen den Gruppen bestanden keine signifikanten Unterschiede in der Effektivität der Therapie und der Dauer der intensivstationären Behandlung. Die Patienten der GHB-Gruppe benötigten jedoch signifikant höhere Dosen von Haloperidol und signifikant niedrigere Dosen von Clonidin. Als Nebenwirkungen traten in der GHB-Gruppe signifikant häufiger eine Hypernatriämie (14 von 21 Patienten) bzw. eine metabolische Alkalose (15 von 21 Patienten) auf. Schlußfolgerungen: Die vegetative Symptomatik war mit GHB besser therapierbar als mit Benzodiazepinen. Als Erklärung für den erhöhten Haloperidolbedarf in der GHB-Gruppe ist eine unzureichende Blockierung des dopaminergen Systems und damit die unzureichende Dämpfung der produktiv-psychotischen Symptomatik sowie ein halluzinogener Effekt der Substanz selbst denkbar. Deshalb kann GHB nur zur Therapie des Alkoholentzugssyndroms mit vegetativer Symptomatik, jedoch nicht bei Halluzinationen empfohlen werden.

    Notes: Abstract   Objective: A chronic alcoholic group following trauma was investigated to determine whether their ICU stay was longer than that of a non-alcoholic group and whether their intercurrent complication rate was increased. Design: Prospective study. Setting: An intensive care unit. Patients: A total of 102 polytraumatized patients were transferred to the ICU after admission to the emergency room and after surgical treatment. Of these patients 69 were chronic alcoholics and 33 were allocated to the non-alcoholic group. The chronic-alcoholic group met the DSM-III-R and ICD-10 criteria for alcohol dependence or chronic alcohol abuse/harmful use. The daily ethanol intake in these patients was ≥60 g. Diagnostic indicators included an alcoholism-related questionnaire (CAGE), conventional laboratory markers and carbohydrate-deficient transferrin. Measurement and results: Major intercurrent complications such as alcohol withdrawal syndrome (AWS), pneumonia, cardiac complications and bleeding disorders were documented and defined according to internationally accepted criteria. Patients did not differ significantly between groups regarding age, TRISS and APACHE score on admission. The rate of major intercurrent complications was 196% in the chronic alcoholic vs 70% in the non-alcoholic group (P=0.0001). Because of the increased intercurrent complication rate, the ICU stay was significantly prolonged in the chronic-alcoholic group by a median period of 9 days. Conclusions: Chronic alcoholics are reported to have an increased risk of morbidity and mortality. However, to our knowledge, nothing is known about the morbidity and mortality of chronic alcoholics in intensive care units following trauma. Since chronic alcoholics in the ICU develop more major complications with a significantly prolonged ICU stay following trauma than non-alcoholics, it seems reasonable to intensify research to identify chronic alcoholics and to prevent alcohol-related complications.

    Description / Table of Contents: Mechanical properties of cold-drawn and cast Grade 2 TitaniumThe static and dynamic properties of Grade 2 Titanium for dental applications are investigated. The typical casting procedures used in dental laboratories lead to a drastic deterioration of the mechanical properties compared to wrought material. This deterioration is caused by changes in microstructure and surface roughness. The experimental results are used to determine opportunities for improvements and their limits.
    Notes: In dieser Arbeit werden die statischen und dynamischen Eigenschaften von in der Zahntechnik verwendetem Titan Grad 2 untersucht. Es zeigt sich, daß die in zahntechnischen Laboratorien üblichen Herstellungsprozesse und Bearbeitungsschritte bei gegossenem Titan eine erhebliche Verschlechterung der Eigenschaften gegenüber kommerziell erhältlichen Ti-Halbzeugen bewirken. Diese Verschlechterung läßt sich auf Änderungen im Gefüge und der Oberflächenrauhigkeit zurückführen. Aus den Untersuchungsergebnissen werden Möglichkeiten und Grenzen für die Optimierung des Herstellungsprozesses für Zahnersatz aus Titan Grad 2 abgeleitet.

    Notes: Multiplicity of steady states of a continuous culture with an inhibitory substrate was used to estimate kinetic parameters under steady-state conditions. A continuous culture of Pseudomonas cepacia G4, using phenol as the sole source of carbon and energy, was overloaded by increasing the dilution rate above the critical dilution rate. The culture was then stabilized in the inhibitory branch by a proportional controller using the carbon dioxide concentration in the reactor exhaust gas as the controlled variable and the dilution rate as the manipulated variable. By variation of the set point, several unstable steady states in the inhibitory branch were investigated and the specific phenol conversion rates calculated. In addition, phenol degradation was investigated under substrate limitation (chemostat operation).The results show that the phenol degradation by P. cepacia can be described by the same set of inhibition parameters under substrate limitation and under high substrate concentrations in the inhibitory branch. Biomass yield and maintenance coefficients were identical. Fitting of the data to various inhibition models resulted in the best fit for the Yano and Koga equation. The well-known Haldane model, which is most often used to describe substrate inhibition by phenol, gave the poorest fit. The described method allows a precise data estimation under steady-state conditions from the maximum of the biological reaction rate up to high substrate concentrations in the inhibitory branch. Inhibition parameter estimation by controlling unstable steady states may thus be useful in avoiding discrepancies between data generated by batch runs and their application to continuous cultures which have been often described in the literature. © 1997 John Wiley & Sons, Inc.
