Percutaneous tansluminal angioplasty(PTA) was done in 38-year-old female patient with membranous obstructionof IVC in the department of Radiology, Seoul National University Hospital. After PTA, pressure gradient between right atrium and IVC was relieved from 16mmHg to 6mmHg. The collateral circulation through hemiazygos vein andreflux into hepatic and right renal vein were disappeared. PTA is suggested to be an effective method in thetreatment of membranous obstruction of IVC.

We report a case of pilomatrixoma presenting in the right cheek of a 6-year-old girl. In the panoramic view, a small, ovoid-shaped, and nonhomogenous calcified mass was superimposed on the right mandibular angle. The mass was located on the skin overlying the right mandibular ramus area in the skull P-A view. The tumor had a strongly reflective pattern with acoustic shadowing in sonographic view. We also illustrate how these lesions can be effectively diagnosed.

OBJECTIVE: To determne whether abnormal results of doble saeening tests for Down syndrome with MSAFP and free B-hCG are associated with adverse pregnancy outcome. METHODS: Between October 1994 and September 1997, 205 among 1731 who were screened had increased risk for Down screening program of CIS biointernational, Fetuses with Chromosomal abnormality or congenital anomalies and less than 35 years of maternal age were excluded from this study. Down syndrome screening test was performed between 14-22 weeks of gestation. RESULTS: Of 1731 women, 205 (13.4%) had increased Down syndrome risk. The pregnancy outcome of women with increased Down syndrome risk were compared with those of women without such risk There were no significant difference in the incidence of preterm labor (6[2.9%] vs 112[7.3%)), premature rupture of the membranes (2[0.9%] vs 56[3.6%]), pregnancy induced hypertension (2[0.9%] vs 36[2.3%]), abruptio placentae (0[0%] vs 2[0.1%]), low birth weight (2[0.9%] vs 21[1.3%]), oligohydramnios (4[1.9%] vs 10[0.6%]), intrauterine fetal death (0[0%] vs 2[0.1%]). CONCLUSION: False positive results of Down syndrome screening test in the 2nd trimester do not appear to be associated with adverse pregnancy outcome. But there are statistically significant increases of adverse pregnancy outcome in wemen with elevation of MSAFP or elevation of free B-hCG.

BACKGROUND/AIMS: Telemedicine is a convenient and efficient tool for remote education in various fields. The telemedicine system can also be used to educate doctors and medical students. The aim of our study was to establish the effectiveness of the telemedical system for use in a live endoscopic multichannel demonstration conference and to test the effectiveness and usefulness of a multicenter-based live endoscopic demonstration through live, interactive, high resolution video transmission using advanced networks and the digital video transport system (DVTS). METHODS: This study is a prospective multicenter pilot study. A live demonstration of an endoscopic submucosal dissection (ESD) and an endoscopic retrograde cholangiopancreatography (ERCP) using advanced network technology was performed. RESULTS: The DVTS successfully transmitted uncompressed, high-resolution, digital lectures with endoscopy video during a multichannel endoscopic live demonstration of ESD and ERCP over multiple advanced networks. The overall satisfaction rating when the endoscopic lecture demonstration was performed by combining DVTS was generally good. CONCLUSIONS: We believe that a multicenter-based live endoscopic demonstration is a very effective conferencing method when using advanced networks and DVTS.

This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited the Health Promotion Center for health examinations volunteered to participate in this study. They were divided into two groups according to their bone status as shown by their T-scores: a non-osteoporotic group and a osteoporotic group. The results are as follows: The mean BMDs of the lumbar spine and femoral neck were 1.21 +/- 0.02 g/cm2 and 0.97 +/- 0.04 g/cm2, respectively. The BMD levels of the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.001, respectively). The heights of the women in the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.01) however, their body weights did not show any significant differences although they tended to be lower. The mean daily intake of energy was 1720 +/- 52 kcal. When the nutrient intake was compared with the Korean recommended dietary allowances (RDA), calcium, Fe, vitamin A and riboflavin intakes were lower than the RDA. Their was no significant difference in the nutrient intake of the non-osteoporotic group and osteoporotic group except for the intakes of protein, fat and niacin. Their was no significant difference between the non-osteoporotic group and the osteoporotic group and all were within the normal range. However, the serum alkaline phosphatase level of the osteoporotic group was significantly higher than that of the non-osteoporotic group (p < 0.001). Height measurements showed positive correlations with lumbar spine bone mineral density (LBMD, r = 0.332, p < 0.01) however there was no correlation with femoral neck bone mineral density (NBMD). Age, age at menarche, body weight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r = 0.236, p < 0.05; r = 0.274, p < 0.05). Serum levels of calcium and phosphorus showed negative correlations with LBMD (r = -0.698, p = 0.0001; r = -0.503, p = 0.0001, respectively). The results suggested that the BMD of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective ways to minimize bone loss would be have a higher intake of niacin and vitamin C rich foods and engaging habitually in physical activity may have a beneficial effect on BMD in the premenopausal period.
