OBJECTIVE: The aim of the present study is to assess the prevalence and related risk factors of suicide ideation among middle and high school students in an urban area. METHODS: We surveyed 3,691 middle and high school students (2,159 male, 1,532 female, 11-19 years of age) using a self-report questionnaire that covered basic socio-demographic data, academic achievements, presence of physical or psychiatric illness, sleep duration on weekdays, time spent at private academies on weekdays and weekends, and subjective needs for counseling. The Beck Depression Inventory (BDI) and Reynolds' Suicidal Ideation Questionnaire (SIQ) were included in the survey. RESULTS: The prevalence of students with high suicide ideation (SIQ > or = 62) was 4.6%. In a logistic regression model, female sex (p = 0.002), younger age (p < 0.001), poor academic achievement (p = 0.043) and higher score of BDI (p < 0.001) were associated with a higher SIQ score. In addition, younger age (p = 0.045) and a higher BDI score (p < 0.001) were associated with a higher SIQ score adolescents having high suicide ideation (SIQ > or = 62). CONCLUSION: Related risk factors of suicide ideation in adolescents were female sex, younger age, poor academic achievement, and a depressive mood. It would be especially helpful to pay more attention to younger adolescents and a depressive mood as a high-risk group. The understanding of these factors will be helpful for providing an effective suicide screening and prevention program for adolescents.

Percutaneous catheter drainage has been reported to bean effective method in the management of selectedpatients with abscess and fluid collection. Its high sucess rate and relatively low complications make theprocedure an alternative to surgery in the individual cases. During past two years percutaneous catheter dainagein 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology,Yonsei Universtiy College of medicine. Here the technique and auathor's results were summarized; 1. The total 25patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal andperirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid draingeunder guidence of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3.The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patientswere clinically improved. The catheter drainage was failed in 2 patients and 3 complications were developed. 4.The success rate of this procefure was 91.3%, failure rate was 8.7% and complication rate was 12%.

We studied 193 Diabetics without any symptoms of coronary artery disease and 39 Normal healthy subjects as Control group, using treadmill exercise test and obtained following results. 1) The positive rate was significantly higher in Diabetics(19.4% in Normal ECG groups and 25.4% in total Diabetics)than Control groups(5.1%)(0.010.05). 5) There was no difference in HbAIC, Total cholesterol and Triglyceride between positive and negative groups(P>0.05). In summary, with exercise test, the positive rate was higher in Diabetics than in Normal control groups and it seemed to be treadmill exercise test is a useful screening method for evaluation of coronary artery disease as well as for assesment of treatment and follow up care.

We herein present a case of rare disease developed in a 43-year-old healthy woman. On her visit, we found several gray colored, well defined, pale, soft, wrinkled atrophic patches on the anterior portion of right upper chest area that is unusual location. The histologic findings showed typical features of lichen sclerosus et atrophicus.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.
