Three Cases of Polymyositis Developed Associated with Chronic Liver Disease / 대한내과학회지

Polymyositis is characterized by symmetrical proximal muscle weakness, nonsuppurative inflammation of striated skeletal muscle, elevation of muscle enzyme, and abnormality of electromyographical change, but its pathogenesis is not clear. The incidence of polymyositis is low, and that associated with chronic liver disease is rare. Clinical importance of polymyositis associated with chronic liver disease is that it is a reversible disease which can be treated with glucocorticoid. We experienced three cases of polymyositis associated with chronic liver disease which was treated with prednisolone. And we report these cases with a brief review of literature. So, the further study about the influence of chronic liver disease on the polymyositis is warranted.

The Risk Factors of Re-bleeding in Peptic Ulcer Patients and the Efficacy of Ethanol Injection Therapy / 대한소화기내시경학회지

BACKGROUND/AIMS: Acute peptic ulcer bleeding is the most common cause of upper gastrointestinal bleeding, and needs urgent management in cases including large amounts of blood loss. Ernergency endoscopy was performed and evaluation was made on the risk factors of rebleeding in peptic ulcer patients and the efficacy of ethanol injection therapy. METHODS: The clinical and endoscopic variables were evaluated according to the rebleeding rates and the efficacy of ethanol injection therapy for hemostasis and prevention of rebleeding in 161 cases including gastric ulcers (GU) with bleeding (M: F 134: 27, mean age 56.5 years) and 136 cases including duodenal ulcers (DU) with bleeding (M: F 111: 25, mean age 40.7 years).
