    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.
