A Case of Liddle's Syndrome Associated with Muscle Weakness / 대한신장학회잡지

Liddle's syndrome was described in 1963 by Liddle, et al., as the disease featuring a hypertension and hypokalemia but with negligible secretion of aldosterone. This syndrome, which morphologically belongs to an abnormal intrinsic tubular disorder with normal renal function, is characterized by hypokalemia, metabolic alkalosis, and hypertension due to the abnormal increase in excretion of potassium in distal tubules or collecting duct and the increase in reabsorption of sodium in distal tubules. This syndrome, which is rare disease, is observed with the low level of plasma and urinary aldosterone and suppressed plasma renin level and is known as dominant mode of inheritance with a family background. The authors paid attention to a 79-year-old man who showed a high blood pressure of 210/130mmHg as well as musle weakness, especially lower extremities due to metabolic alkalosis featuring a hypokalemia level of 2.0mEq/L when he was admitted to our hospital, Because his serum potassium were not improved with the medication of intravenous potassium supply, and his blood pressure continued to be high without the improvement of muscle weakness, we prescribed 300mg of spironolactone for two weeks. His symptom, however, was not cured. Then, instead of spironolactone, we prescribed 150mg of triamterene and a low salt diet which finally improved his symptoms. Because there has been no reported case in the Korean medical literature, we report a case of successfully treated Liddle's syndrome due to triamterene administration.

A Case of Duodenal Tuberculosis Which is Hardly Differentiated from Duodenal Lymphoma / 대한소화기내시경학회지

Primary duodenal tuberculosis, duodenal Crohn's disease, duodenal lymphoma, duodenal cancer is extremely rare event. Vague upper abdominal pain, weight loss(10 Kg) had been present for several months in a 52-yeer-old woman. Endoscopy revealed an irregular ulcer in the second part of the duodenum. CT of the abdomen revealed pooly defined hypodense and centrally low density masses along the hepatoduodenal ligament, with poor separation from the head of pancreas. Hypotonic duodenogram showed spiculation and smooth indentation of mucosal fold at medical aspect of sup. portion m descending duodenum. ERCP showed medially displaced distal CBD and main pancreaticduct. At first, lymphoma, cancer, Crohn's disease, duodenal tuberculosis were considered in the differential diagnosis. Endoscopic biopsy sepecimen of duodenal lesion showed atypical lymphocytes. We excluded the diagnosis of the duodenal cancer. We started anti-tubercular drugs because in our country tuberculosis is endemic. After 4 weeks anti-tuberculosis therapy, follow up endoscopy and biopsy specimens showed healing stage of duodenal ulcer and chronic granulomatous inflammation with multinucleated giant cell. Thus we concluded that when duodenal lesion which could not confirmed histopathologically it was wise to start antitubercular therapy than to perform exploraparotomic dianostic procedures.
