A Case of Hypertrophic Form of Duodenal Tuberculosis Mimiking Duodenal Cancer / 대한소화기내시경학회지

The prevalence of intestinal tuberculosis has been markedly decreased with the development of antituberculous chemotherapy, improved economic conditions, preventive medicine and early detection and treatment of pulmonary tuberculosis. An even more impressive resurgence of pulmonary and extrapulmonary tuberculosis has been seen in recent years among persons infected with the human immunodeficiency virus. The most common site of intestinal tuberculosis is the ileocecal region, and duodenum is a rare site. Symptoms and signs of duodenal tuberculosis are nonspecific. The gross pathologic appearance of the duodenal tuberculous lesions has to its traditional categorization into three forms: 1) ulcerative, 2) hypertrophic, and 3) ulcerohypertrophic (mixed). Hypertrophic lesions of the duodenal tuberculosis should be differentiated from duodenal adenocarcinoma and lymphoma. We herein report a case of duodenal tuberculosis presenting as intraluminal protruding mass in gastroduodenoscopy and multiple intraabdominal lymphadenopathy on abdominal CT. We have confirmed the duodenal tuberculosis by endoscopic biopsy, and review the current literatures.

Endoscopic Removal of Fish Bones Impacted in the Rectosigmid Colon / 대한소화기내시경학회지

Impaction of an ingested foreign body in the colon is uncommon but surgical or endoscopic intervention is occasionally needed when serious complications such as perforation, obstruction or hemorrhage occur. Several factors may predispose a patient to ingestion and subsequent impaction of lower intestinal foreign body. It is more common in the elderly who wear dentures, in the mentally infirm, in chronic alcoholics or rapid eating. The majority of impaction occurs at narrowing and angulation such as ileocecal valve or rectosigmoid junction. The diagnosis of lower intestinal foreign body should be considered, among more common conditions, in the differential diagnosis of elderly patients who present with altered bowel habits. We report the case with a literature review that successfully endoscopically removed the fish bones impacted in the rectosigmoid colon complicated by rectal bleeding.

A Case of Acute Renal Failure Caused by Amphetamine-Associated Rhabdomyolysis / 대한신장학회잡지

Amphetamine toxicity is well known in western countries since several decades ago. Taken in excessive amount, amphetamine causes systemic symptoms such as hyperpyrexia, tachycardia, hyperkinesia, delirium, seizure and circulatory collapse. Acute renal failure following amphetamine ingestion is caused by the direct toxicity of the drug, circulatory collapse, coagulopathy, retroperitoneal hematoma or tubular obstruction by rhabdomyolysis. This is a case of a amphetamine intoxicated 41-year male patient presenting with features of acute renal failure, which is not accompanied by circulatory collapse, nor by coagulopathy. Muscle enzymes and bone scan findings were compatible with nontraumatic muscle injuries, and the renal pathology was tubular necrosis with specific myoglobin casts. Therefore a drug induced rhabdomyolysis causing myoglobinuric tubular injury is highly suspected. The fact that the outcome of the renal disease itself was good despite fatal dosage of this drug is also compatible with myoglobinuric renal failures reported by foreign authors. This is probably the first reported case of acute renal failure caused by amphetamine associated rhabdomyolysis in Korea.
