Transfer of 137Cs into fish in small forest lakes.

The transfer of (137)Cs into fish in seepage and drainage lakes from 1988 to 1992 was analysed using linear regression. Empirical results for (137)Cs in lake water and fish were used to calculate concentration factors (CFs). In the drainage lakes the CF decreased during the study period by 9% per year whereas in the seepage lakes the CF increased significantly by 4.3% per year. The transfer of (137)Cs into pike was significantly (1.6 times) higher than that into perch. The CF increased on average by 3.4% for each 1-cm increase in the median size of perch. The relationship between the water chemistry and the CF differed between clear-water seepage and brown-water drainage lakes.

Primary cutaneous aspergillosis in a patient with a solid organ transplant: case report and review of the literature.

GOAL: To understand primary cutaneous aspergillosis to better manage patients with the condition. OBJECTIVES: Upon completion of this activity, dermatologists and general practitioners should be able to: 1. Describe risk factors for Aspergillus infection. 2. Identify diagnostic methods for primary cutaneous aspergillosis. 3. Discuss treatment options for primary cutaneous aspergillosis. Primary cutaneous aspergillosis is an uncommon disease in immunocompetent individuals that often affects immunosuppressed hosts. We present the first reported case of primary cutaneous aspergillosis in a solid organ transplant recipient caused by Aspergillus niger. Fruiting bodies were isolated from a necrotic ulcer arising in a surgical wound. Debridement alone failed to resolve the infection, emphasizing the need for early antifungal treatment combined with surgical management of this infection.
