    Notes: Summary Following the manifestation of humidifier fever in a number of workers in a carpet yarn texturing plant, a comparative study was begun of a group of workers exposed to fungi from the air-conditioning system and a control group not so exposed. For both group of workers anamnestic data were collected, intracutaneous skin tests were performed, certain lung function parameters were determined, and the presence of antibodies to a number of antigens from the system was tested for. It was found that the group of exposed workers had a significantly higher rate of positive intracutaneous skin test than non-exposed workers. Additionally, their serology was more often positive. Both positive skin test and positive serology were more frequent in non-smokers than in smokers. A positive immediate skin reaction among exposed workers was found to correlate with an FEF25–75 reduction during the working week. A positive delayed skin reaction among exposed workers correlated with a lower FVC prior to the start of the working week than recorded for non-exposed workers. A positive serology in exposed workers did not correlate with a difference in lung function compared with non-exposed workers, nor was there a correlation with a change in lung function in the course of the working week. When humidifier fever is diagnosed, steps should be taken to reduce exposure. It would also appear desirable to keep exposed workers under medical observation and to monitor the subsequent development of their lung function.

    Arteriovenous malformation of the great cerebral vein (of Galen) in a newborn (1987)
    Springer
    European journal of pediatrics 146 (1987), S. 87-89

    ISSN: 1432-1076

    Notes: Abstract This is a report of a case with an arteriovenous (a.v.) malformation of the great cerebral vein. Applicable diagnostic procedures are reviewed. The initial diagnostic procedure in the approach to an a.v. malformation of the great vein of Galen is cerebral ultrasound. The findings in our patient are compared with those reported in the literature.

    Description / Table of Contents: Zusammenfassung In dieser Arbeit werden, für eine geschlossene eigentlich konvexe Funktionf, Existenz und Eindeutigkeit eines minimierenden Vektors untersucht und frühere Resultate zu diesem Thema verallgemeinert. Für konvexe Funktionen mit zusätzlichen Eigenschaften werden notwendige und hinreichende Bedingungen für Existenz bzw. Eindeutigkeit angegeben. Fallsf sein Minimum inx annimmt, ohne daßx eindeutig ist, werden lineare Funktionend'x mit eindeutigen oder beschränkten Werten identifiziert. Die Anwendbarkeit der Resultate wird in der Regressionsanalyse von Lebensdauern, etwa mit dem Cox Modell, demonstriert.
    Notes: Abstract In this paper, theorems on existence and uniqueness of a vector minimizing a closed proper convex functionf are given, extending previous results on this topic. Necessary and sufficient conditions are presented for convex functions with additional properties. Iff attains its infimum atx withoutx being unique, linear functionsd'x with unique or bounded values are identified. Applicability of results is demonstrated in regression analysis of failure times, including the Cox model.
