Change of Clostridium difficile Colitis during Recent 10 Years in Korea / 대한소화기학회지

BACKGROUND/AIMS: Our clinical experience and recent published literatures suggest that Clostridium difficile colitis (CDC) has become more common and potentially more pathogenic in recent years. The aim of study was to evaluate changes in the epidemiological features of CDC in hospitalized patients in Korea. METHODS: We retrospectively reviewed all patients of CDC diagnosed at Kangnam St. Mary Hospital from 1998 to 2007. CDC was defined as having a positive C. difficile cytotoxicity assay, or endoscopic or pathologic evidence of CDC. RESULTS: A total of 189 cases (male 73, female 116, mean age 63.3 years) of CDC were diagnosed during the study period. The prevalence of CDC increased from 1.9/10,000 patient admissions in 1998-1999 to 8.82/10,000 patient admissions in 2006-2007. One hundred sixty three indication for cases (86.2%) of patients identified a prior use of antibiotics in the 2 months preceding diagnosis. The most common antibiotic use was prophylactic use during perioperational period (33.3%) followed by pneumonia (23.3%). The overall response rate to initial antibiotics was 82.7%. One hundred seventy two (91%) patients were initially treated with metronidazole. The response rate was 84.3%. All patients with initial failure to metronidazole were successfully treated by vancomycin. The response rate of vancomycin as first treatment was 80%. Three deaths were associated with CDC despite the use of combination of metronidazole and vancomycin. CONCLUSIONS: The prevalence of CDC in hospitalized patients in Korea significantly increased from 1998 to 2007.

A Case of Esophageal Pyogenic Granuloma / 대한소화기내시경학회지

Pyogenic granulomas (PGs) are rare benign lobular capillary hemangiomas that occur on the skin or mucosa. The most common sites of PG occurrence are the skin, lip, face and finger. This entity is extremely rare in the alimentary tract, with the exception of the oral cavity. We describe here a 72-year-old man who presented with dysphagia due to the presence of a pyogenic granuloma. The tumor was located in the mid-esophagus and it was treated with endoscopic submucosal dissection. PG is considered a lesion of reactive origin that may develop in response to trauma, infection, pregnancy, angiogenic factors or hormones. Gastrointestinal PG need to be treated because it is a rare cause of gastrointestinal hemorrhage, and it is hard to differentiate from tumorous conditions such as Kaposi's sarcoma.

Remediable Hyperglycemia in a Patient with Weber-Christian Disease / 대한류마티스학회지

Weber-Christian disease (WCD) is an inflammatory disease of subcutaneous fat tissue which is characterized by relapsing, febrile tender nodules and histologically lobular panniculitis. Any area of the body containing fat can be affected by WCD. Several cases of WCD have been reported as involvement of the heart, lung, liver and kidney. Acute illness (ex. acute myocardiac infarction, infection, etc) can be complicated with stress-related hyperglycemia and increase insulin restistance. Finally this case show that Weber-Christian disease accompanied by marked hyperglycemia and insulin resistance, which resolved soon after corticosteroid.

A Case of ANCA-positive Crescentic Glomerulonephritis after Propylthiouracil Treatment in Graves' Disease / 대한신장학회잡지

Propylthiouracil (PTU) therapy is commonly used in the treatment of Graves' disease, but often accompanies several side effects, including a mild increase in liver enzymes, leukopenia, skin rash, and arthralgia. ANCA-positive vasculitis and crescentic glomerulonephritis have been rarely reported in patients suffering from (with) Graves' disease and treated with PTU. We experienced a rare case of ANCA-positive crescentic glomerulonephritis presenting rapid progressive renal failure in a 30-year-old woman, suffering from Graves' disease and treated with PTU for 6 years. She was admitted with dyspnea for 1 day and fever, gross hematuria, arthralgia and sore throat for several days. Her chest X-ray revealed moderate cardiomegaly, bilateral pulmonary edema, and bilateral pleural effusion. She had a palpable, firm, diffuse goiter. Anti-myeloperoxidase (anti-MPO) antibody and anti-protease 3 (anti-PR3) antibody were both positive by ELISA. A percutaneous renal biopsy showed crescentic golmerulonephritis showing active cellular crescent formation with some inflammatory cell infiltration and mesangial cell proliferation. Cellular crescents were present in 2 of 3 glomeruli. Immunofluorescence stain showed weak granular deposits of IgG, IgM and C3 in the mesangium and capillary wall. ANCA-positive crescentic glomerulonephritis associated with PTU was diagnosed. The patient was started on intravenous methylprednisolone 250 mg 2 times daily, and then oral prednisolone 100 mg every other day and PTU was discontinued. Her renal function was recovered gradually and anti-MPO antibody and anti-PR3 antibody subsequently fell. Second biopsy, 7 months after first biopsy, showed focal global glomerulosclerosis. 16 months after first biopsy. she had stable renal function with mild renal insufficiency and euthyroid state.
