A Case of Lymphoepithelial Cyst of the Pancreas Showing Characteristic Findings on Endoscopic Ultrasonography / 대한소화기내시경학회지

Lymphoepithelial cyst of the pancreas is a rare benign cystic tumor which is histologically characterized by cyst containing keratin, lined by mature squamous epithelium surrounded by lymphoid tissue, often with prominent follicles. Cystic lesions of the pancreas are more often detected because sensitive abdominal imaging tests are used for multiple indications, but preoperative differential diagnosis is difficult despite the advancements of imaging technologies. We herein report a case of lymphoepithelial cyst incidentally found on routine abdominal ultrasonography which showed characteristic findings on endoscopic ultrasonography preoperatively and discuss the radiologic features of lymphoepithelial cyst.

A Case of Acute Theophylline Intoxication Treated with Hemoperfusion / 대한신장학회잡지

Theophylline has been used for more than 50 years to treat bronchial asthma, and theophylline toxicity continues to be an encountered clinical problem. With suicidal intention, a 61-year-old depressive male patient was sent to the hospital after ingestion of overdose theophylline. He had been followed up for bronchial asthma with about 10 microgram/ mL average plasma theophylline level. On arrival, he complained of dyspnea, palpitation and the plasma theophylline level was 252 microgram/mL. After 2 hours of ingestion, hypotension and tachycardia developed (Systolic blood pressure 50 mmHg, heart rate 190/ min). Other symptoms and signs were stuporous mental state and hypoxemia. Patient's peak plasma theophylline level reached 402 microgram/mL after 3 hours. beta-blocker, dopamine and midazolam were used for control of tachycardia, hypotension and prevention of seizure respectively. After Gastric lavage and administration of charchoal, he was treated with hemoperfusion for 3.5 hours, and serum level decreased. The patient was discharged in good health after 17 days.
