The importance of opiate dependence or abuse is increasing in the context of the increasing number of cancer survivors and patients with chronic cancer pain. Cancer patients are likely to have psychological disorders such as depression, anxiety, and sleep disturbances. It is important to distinguish these psychological disorders from opiate dependence or abuse. We report a case of a cancer patient with major depressive disorder who was initially suspected of opiate dependence or abuse.

Waldenstr m's macroglobulinemia(WM) is a disorder of malignant proliferation of plasmacyoid lymphocytes and monoclonal immunoglobulin M. The renal complications of WM are less common and severe than that of multiple myeloma. We present a case of WM which involved the kidney as massive proteinuria, hematuria and renal failure. A biopy specimen of the kidney reveals the intraglomerular hyaline thrombi of immunoglobulin M paraprotein. Three cycles of plasmapheresis and systemic chemotherapy with chlorambucil and prednisolone show improvement in his renal manifestations. We suppose the glomerulonephritis caused by hyaline thrombi in WM may be reversible, at least in its early stage.

In recent years, there has been a rapid decrease in amphibian populations worldwide, and infectious diseases have been associated with this decline. Diseased frogs inhabiting Korea were collected from fields, and the diseases were identified by morphological and molecular analyses. Two fungal diseases-saprolegniasis and chromomycosis-were detected in the frogs. Saprolegniasis caused by Saprolegnia spp. was found in Rana plancyi chosenica from Gangwon-do and Rana huanrenensis from Chungbuk. Chromomycosis, which is caused by infection with Cladosporium cladosporioides, was detected in Rana catesbeiana from Busan.
