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.

OBJECTIVES: This study was carried out to analyze the characteristics of occupational diseases among health care workers in Korea. METHODS: Using the database of the Korea Labor Welfare Corporation (KLWC), 5, 460 approved occupational disease cases, between Jan 1, 1999 and Dec 31, 2000, and approved by the Jun 30, 2001, were collected. Of these, the 142 health care worker cases were investigated. RESULTS: The proportion of health care workers among the total cases reported in 1999 and 2000 was 2.6%, respectively. The diseases were infectious in 61 (43.0%), cerebro-cardiovascular in 60 (42.3%) and musculoskeletal in 18 cases (12.6%). The distributions of the occupational diseases by sex were 59 (41.5%) and 83 cases (58.5%), in males and females, respectively. The distributions of the occupational diseases by age were 64 (45.1%), 30 (21.1%), 25 (17.6%) and 17 cases (12.0%), in their 20s, 30s, 40s and 50s, respectively. For the cases of infectious diseases by age there were 48 (78.7%) in their 20s and 12 (19.7%) in their 30s, for the cases of cerebro-cardiovascular diseases by age there were 17 (28.3%) in their 40s, 16 (26.7%) in their 50s and 12 (20.0%) in their 20s, and for the cases of musculoskeletal diseases there were 7 (38.9%) in their 30s and 4 (22.2%) in their 20s. The distributions of the cases of occupational diseases by department were 64 (45.1%), 19 (13.4%), 18 (12.7%), and 10 (7.0%) in the nursing, doctors, officers, and food services departments, respectively. CONCLUSIONS: The major occupational diseases of health care workers, as approved by the KLWC, were the infectious, cerebro-cardiovascular and musculoskeletal diseases. A special management policy must be considered to prevent occupational diseases of health care workers in Korea.
