Naturschutzforschung am Auerhuhn in der Schweiz: eine Übersicht

The Western Capercaille Tetrao urogallus is a large forest grouse with narrow habitat preferences and large home ranges. As Capercaille populations are declining in most of their central European range and the species has been shown to be an umbrella for high species richness, a profound knowledge of the species' ecology is essential for the conservation of the charismatic bird.

Pneumocystis-carinii-Pneumonie bei Säuglingen mit vertikaler HIV-Infektion in der Schweiz [Pneumocystis carinii pneumonia in infants with vertically acquired HIV infection in Switzerland]

OBJECTIVE: Review of incidence, clinical picture, therapy, and outcome of Pneumocystis carinii pneumonia (PCP) in infants with vertically-acquired HIV infection in Switzerland. METHODS: Inquiry among members of the Swiss Pediatrics AIDS Group, review of the data base of the Swiss Neonatal HIV Study and retrospective analysis of the charts from infants with PCP. RESULTS: Since 1986 PCP has been diagnosed in 10 out of 107 infants with vertically-acquired HIV infection. PCP occurred in 7 infants at the age of 3-6 months and in 3 at the age of 9-11 months. 4 infants showed symptoms related to HIV infection before developing PCP. Before the development of PCP, infection with HIV had been ascertained in 6 infants. In 2 the diagnosis was still unclear and in the 2 remaining the risk of HIV infection was not known. None of the infants was on primary prophylaxis against PCP. Signs and symptoms of PCP included cough and tachypnea (100%) as well as high fever up to 40 degrees C (90%). Transcutaneous oxygen saturation was 70-95%. Chest X-rays revealed interstitial infiltrates in 6 infants, localized infiltrates in 2 and interstitial as well as localized infiltrates in 2. The CD4+ cell count was, with one exception, < 1500/microliters, i.e. below the normal value for age. Side effects of high dose cotrimoxazole were noted in 6 patients. 5 infants required intubation and mechanical ventilation. 4 infants died due to PCP, including 3 of those who required intubation and mechanical ventilation. CONCLUSIONS: PCP in infants with vertically-acquired HIV infection preferentially occurs at the age of 3 to 6 months and is often lethal, especially in patients requiring intubation. Evaluation for HIV infection should be done as early as possible in order to introduce primary PCP prophylaxis in infants at risk for this opportunistic infection.

Entwicklung des Vertriebs von Präservativen in der Schweiz : 1986-2009.

Die Förderung des Präservativgebrauchs beim Geschlechtsverkehr gehört zu den zentralen Elementen der HIV/Aids-Präventionsstrategie in der Schweiz. Die Entwicklung des Zugangs zu Präservativen in der Schweiz wird seit 1986 von der Unité d'Evaluation de Programmes de Prévention des Instituts für Sozial- und Präventivmedizin in Lausanne untersucht. Diese Arbeit erfolgte zunächst im Rahmen der Evaluation der Nationalen HIV/Aids-Präventionsstrategie des BAG und ist seit 2000 Teil des Monitorings dieser Prävention.
