Several acute neurological syndromes can be triggered by Introduction: immune events. Hepatitis E virus (HEV), an emerging infectious disease, can be one of these triggers. We report the case of a 36-year-old man that presented nausea Case report: and a dull abdominal pain for a week and then felt an acute neuralgic pain involving both shoulders that lasted(More)
INTRODUCTION Ifosfamide is a chemotherapy agent infrequently associated with liver toxicity. To the best of our knowledge, this report is the first to describe serious liver toxicity associated with ifosfamide used in combination with doxorubicin that caused acute but fully reversible liver failure and encephalopathy. This report reviews the possible(More)
INTRODUCTION It is well-known that continuous ambulatory peritoneal dialysis (CAPD) is associated with complications. And some of these complications are well-demonstrated as abnormalities on computed tomographic peritoneogram (CTP). The objective of our study is to document the serial changes of these complications. METHODS We retrospectively reviewed(More)
