Three cases of liver injury caused by Sennomotokounou, a Chinese dietary supplement for weight loss.

Dietary supplements have become very popular worldwide because they are believed to be safe with few side effects. Here, we report three cases of liver injury caused by Sennomotokounou, a Chinese dietary supplement for weight reduction. All patients developed acute hepatotoxicity and recovered spontaneously after withdrawal of dietary product. This product contains fenfluramine, n-nitroso-fenfluramine, and dried thyroid tissue powder. In Japan, the regulatory agency for drug and food safety received 120 reports of hepatotoxicity associated with Sennomotokounou between 2000 and 2002. Physicians should inquire about the use of dietary supplements whenever patients present with unexplained acute liver dysfunction.

Ulcerative colitis in monozygotic twin sisters.

We present a rare occurrence of woman monozygotic twins with ulcerative colitis (UC). A 21-year-old woman came to our hospital because of diarrhea, abdominal pain and hematochezia. We diagnosed this case as proctitis type UC by endoscopic and histological findings. Six months later, her twin sister developed total colitis type UC. Both twins had HLA-A24, B52, DR2, and DQ1 serological types, and had DRB1*1502 DNA type, previously shown to be associated with UC. This case report suggested an association of genetic factor together with environmental factors in the etiology for UC.
