PURPOSE: The purpose of this study is to evaluate the gadolinium-enhanced MR imaging findings of cerebral venous angiomas, and to compare those findings with those of cerebral angiography. MATERIALS AND METHODS: We reviewed the findings of gadolinium-enhanced MR images of 11 cases with angiographically proved cerebral venous angiomas. We obtained Tl-and T2-weighted images with gadoliniumenhanced Tl-weighted images at a 0.5 T MR imager with a spin-echo technique. We analyzed the location and signal intensity of the lesion, pattern of contrast enhancement, the distribution of draining veins and medullary veins before and after contrast enhancement, and then compared with the findings of cerebral angiography. RESULTS: The characteristic central tubular signal void structure showed low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images in all cases. After gadolinium enhancement, we could find a characteristic enhancement of all medullary and central veins in 7 cases. CONCLUSION: Gadolinium-enhanced MR image was useful in the diagnosis of venous angiomas especially in the detection of medullary veins. The invasive cerebral angiography could be replaced by this technique in this disease.

Three cases of sclerosing stromal tumor of the ovary are presented. All three patients were nulliparous young wemen of 23~25 years of age, presenting with menstrual irregularity for 6 months to 4 years. Grossly the tumors ranged in size from 8 to 22cm in greatest diameter, showing gray white to yellow solid or predominantly cystic tissue with serous fluid. The common microscopic finding was that of cellular areas admixed with densel fibrous and/or edematous tissue, presenting pseudolobular appearance. Two types of tumor cells were rounded cells with clear vacuolated cytoplasm and less numerous spindle shaped cells. Postoperative course was uneventful and menstrual irregularity disappeared postoperatively. In case 2, the patient got pregnant after 1 year and 4 months. This clinical course suggests that sclerosing stromal tumor of the ovary may be endocrinologically active.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic syndrome including insulin resistance, hypertension, dyslipidemia, central obesity, type 2 diabetes, and cardiovascular disease. In NAFLD, insulin resistance plays an important role in the progression of liver damage. In this study, we evaluated insulin resistance, plasma adiponectin, hepatic steatosis, and their association in adults with normal liver transaminase concentrations. METHODS: We analyzed 111 subjects, aged over 20 years old, who visited the Health Management Center at Chung-Ang University Hospital between May 2006 and August 2006. They had neither history nor clinical evidence of diabetes, cardiovascular or liver disease. They were divided into three groups by the degree of hepatic steatosis based on ultrasound findings. Anthropometric parameters were measured and blood samples were drawn after eight hours of fasting. RESULTS: Hepatic steatosis had a positive correlation with body mass index, waist circumference, blood pressure, triglycerides, HOMA-IR, and QUICKI. Moreover, it had a negative correlation with high-density lipoprotein cholesterol and adiponectin. Triglycerides, Adiponectin, and QUICKI were independent variables in predicting the degree of hepatic steatosis. CONCLUSION: This finding suggests that triglycerides and plasma adiponectin are independent predictors of hepatic steatosis in adults with normal liver transaminase concentrations.

Primary ampullary carcinoma is one of rare gastrointestinal malignancies which can be diagnosed by ERCP and endoscopic biopsy. However, sometimes it is difficult to comfirm the diagnosis when the tumor is not exposed out of orifice of ampulla. Recently, we diagnosed early stage ampullary carcinoma using endoscopic sphincetrotomy for the exposure of tumor in 54 year old woman ia whom ERCP revealed rather impacted stone like filling defect in distal common bile duct. we describe a case of papillary adenocarcinoma of the ampulla of Vater diagnosed by edoscopic sphincterotomy.

OBJECTIVES: To analyze the characteristics of occupational diseases among agricultural, forestry and fishery workers compensated under the Industrial Accident Compensation Insurance that is operated by the Korea Labor Welfare Corporation (KLWC). METHODS: Using the KLWC database, we collected 667 cases of occupational disease compensated during the 8 years between 1 January 1998 and 31 December 2005. We analyzed the characteristics of occupational diseases using the KLWC electronic data and the data investigated by the Korea Occupational Safety and Health Agency. RESULTS: KLWC approved 667 cases, including 69 deaths (10.3%). Men accounted for 76.0%of the approved cases. The most common age group was 50~59 years of age (37.3%). The most common size of enterprise was 5 to 49 workers (47.5%). The proportion of occupational diseases was 54.1%, of which 45.9% was work-related. Among occupational diseases, the most common was skin diseases (147 cases, 40.7%), followed by infectious diseases (131 cases, 36.3%), including scrub typhus (123 cases) and intoxication (40 cases, 11.1%). The causal hazardous agents were biological (320 cases, 88.6%), chemical (29 cases, 8.0%), and physical (11 cases, 3.0%). The major type of industry and occupation were forestry (445 cases, 66.7%) and elementary (151 among 235 cases, 89.3%), respectively. CONCLUSIONS: Major compensated occupational diseases were infectious diseases, including scrubtyphus, skin diseases and toxic disease, which occurred among workers who were older, and had short tenure and elementary occupation, and these workers were out of the occupational health policy. A management policy must be established to prevent occupational diseases occurring in such vulnerable workers.
