Radilogic findings in 30 patients with intestinal tubeculosis and 10 patients with intestinal Behcet'sdiseases, who had been diagnosed at seoul National University Hospital during the recent 5 years, were analysedretrospectively to evaluate the radiologic differential diagnosis of the two diseases. Intestinal tuberculosisseverely involved the cecum, the ileocecal valve, the distal ileum and colons, but Behcet's disease mainlyinvolved th distal ileum and infrequently the ileocecal valve and the cecum. The ulcers in tuberculosis wereusually multiple small barium collected areas among psuedopolyps on the contrary, those in Behcet's disease weremultiple, discrete, well marginated, geographic, ring-like deep penetrating or collar-button shaped. Intestinaltuberculosis tended to involved long segments of intestines, with severer mucosal irregularity and deformity ofthe ileocecal valve and the ascending colon in comparison with Behcet's disease. Mesenteric and/or peritonealinvolvment were accompanied in 1/3 cases of intestinal tuberculosis,a nd active pulmonary tuberculosis or pleuraleffusion also in 1/3 cases of intestinal tuberculosis.

Background: This study aimed to investigate the relationship between changes in employment status and new-onset depressive symptoms through a one-year follow-up of permanent waged workers. Methods: We analyzed the open-source data from the Korea Welfare Panel Study. Using the 2017 data, we selected 2,314 permanent waged workers aged 19 to 59 years without depressive symptoms as a base group. The final analysis targeted 2,073 workers who were followed up in 2018. In 2018, there were five categories of employment status for workers who were followed up: permanent, precarious, unemployed, self-employed, and economically inactive. Multiple logistic regression was used to determine the association between employment status change and new-onset depressive symptoms. Results: Adjusted multiple logistic regression analysis showed that among male workers, workers who went from permanent status to being unemployed (odds ratio: 4.50, 95% confidence interval: 1.19 to 17.06) and from permanent status to being precarious workers (odds ratio: 3.15, 95% confidence interval: 1.30 to 7.65) had significantly high levels of new-onset depressive symptoms compared with those who retained their permanent employment status. There were no significant increases in new-onset depressive symptoms of male workers who went from permanent status to being self-employed or economically inactive. On the other hand, no significant differences were found among female workers. Conclusion Our study suggests that the change of employment status to precarious workers or unemployment can cause new-onset depressive symptoms in male permanent waged workers.

BACKGROUND: This study was conducted to reveal the health effects of air pollution on the residents living near waste treatment plant. METHODS: We sampled 190 residents as the hogh exposed group, 192 residents as the moderate group, and 139 residents as the low exposed group according to the geographical distances from the waste treatment plant. Self-administered questionnaires for prevalence of respiratory disease, irritation symptoms of mucous membrane (eye, nose, thoat, skin, and respiratory tract), gastrointestinal symptoms, other nonspecific symptoms were conducted. We measured the concentrations of total suspened partcles, Zn, Cu, Cr, Ni, Pb, Cd and As in 3 exposed area. RESULT: Airborne concentrations of total suspended particles measured in exposed area were 485, 365, and 332 micro gram/m(3) which excees the limit value. Airborne concentrations of Zn, Cu, Cr, Ni, Pb, Cd and As were not excees the limit value. The prevalence of respiratory disease of high exposed group (16.8%) was significantly higher than that of moderate group (3.6%) and low exposed group (5.0%). The sysptom score of irrtation sysptoms of mucous membrane, gastrointestinal sysptoms, and other nonspecific sysptoms were increased with exposed level. In multiple linear regression, exposure level was related to all sysptom scores significantly. CONCLUSION: These results suggest that the air pollution of waste treatment plant would influence prevalence of respiratory disease, induce irritation of mucous membrane, gastrointestinal symptoms, and other nonspecific sysptoms.

PURPOSE: The image quality of magnetic resonance angiography (MRA) varies according to the imaging techniques applied and the parameters affected by blood flow patterns, as well as by the shape of the blood vessels. This study was designed to assess the influence on signal intensity and its distribution of the geometry of these vessels, the imaging parameters, and the concentration of contrast media in MRA of stenosis and aneurysm models. MATERIALS AND METHODS: MRA was performed in stenosis and aneurysm models made of glass tubes, using pulsatile flow with viscosity and flow profile similar to those of blood. Slice and maximum intensity projection (MIP) images were obtained using various imaging techniques and parameters ; there was variation in repetition time, flip angle, imaging planes, and concentrations of contrast media. On slice images of three-dimensional (3D) time-of-flight (TOF) techniques, flow signal intensity was measured at five locations in the models, and contrast ratio was calculated as the difference between flow signal intensity (SI) and background signal intensity (SIb) divided by background signal intensity or (SI-SIb)/SIb. MIP images obtained by various techniques and using various parameters were also analyzed, with emphasis in the stenosis model on demonstrated degree of stenosis, severity of signal void and image distortion, and in the aneurysm model, on degree of visualization, distortion of contour and distribution of signals. RESULTS: In 3D TOF, the shortest TR (36 msec) and the largest FA (50 degree) resulted in the highest contrast ratio, but larger flip angles did not effectively demonstrate the demonstration of the peripheral part of the aneurysm . Loss of signal was most prominent in images of the stenosis model obtained with parallel or oblique planes to the flow direction. The two-dimensional TOF technique also caused signal void in stenosis, but precisely demonstrated the aneurysm, with dense opacification of the peripheral part. The phase contrast technique showed some distortions in the imaging of stenosis, and partial opacification of ananeurysm. Contrast enhanced imaging offered no advantages in the imaging of the stenosis, but was excellent for demonstration of the aneurysm. CONCLUSION: This study demonstrates a spectrum of MRA images of stenosis and aneurysm model according to variation in imaging parameters and the concentration of contrast media.

The Dandy-Walker syndrome is a developmental disorder of the brain characterized by cystic dilatation of the fourth ventricle and agenesis or hypoplasia of the cerebellar vermis. We experinced a case of Dandy-Walker syndrome with complex cardiac anomaly in female newborn who presented with apnea at birth. Physical examination showed coloboma on left eye, low estting malformed ear, and high arched palate. Autopsy revealed cystic dilatation of the fourth ventricle with secondary loss of cerebellar vermis. The floor of the fourth ventricle is exposed through this defect. Heart showed aortic atresia and univentricular heart. The case is reported with the review of the literatures.
