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.

A case of aneurysmal bone cyst is reported in a 23 years old male, who complained of pain and tenderness on the right lateral aspect of thigh, This case had been treated with radical curettage and autogenous bone graft, but eight months later the radiological evidence of recurrence was present. So he was reoperated and he has been recovered relatively gradually, Roensgenograms of 7 montbs duration after reoperation showed abundent new bone formtion and no evidence of recurrence.

Ewing's Sarcoma is a rapidly growing malignant neoplasm that arises from primitive cells of the bone marrow in young persons. This case, a seventeen year-old male, complained of pain and swelling on the both knee. He had been treated under the impression of osteomyelitis at several local clinics. Clinically, malaise and high fever were continued during admission period. Microspically it was confirmed as Ewing's Sarcoma and then he was discharged. Presently he is under the radiation therapy.

A new crush anastomosis model which can be evaluated as crush energy was established on the femoral artery and vein of the rats weighing 250g on the average. The degrees of vessel injury were evaluated as crush energy. The arteries underwent the crush injury with the energy of 0.3J, 0.4J, 0.5J, while the reins were crushed with the energy of 0.2J, 0.3J, 0.4J respectively then the vessels in each group were divided and anastomoses by a standard microsurgical technique. Saline and heparin were used as a luminal topical agent and systemic one, which allowed contact with the damaged endothelium. The heparin treated group had a patency rate of 95%(0.3J), 87.5%(0.4J), 40%(0.5J) vs. 55%(0.3J), 15%(0.4J), 10%(0.5J) in the saline irrigated group in the femoral arteries, which had the patency rate of 82.5%(0.2J), 72.5%(0.3J), 42.5%(0.4J) vs. 35%(0.2J), 12.5%(0.3J), 7.5%(0.4J) in the saline irrigated group in the femoral vein at 1 day. There was a energy-related decrease in patency rate. These findings indicate that the crush model of 0.4J in the rat femoral artery, 0.3J in the rat femoral vein is a reliable and reproducible thrombosis model. The model described in this study is to be used to evaluate and assess the ability of antithrombotic agent in preventing thrombosis at the anastomotic site.

BACKGROUND: Trauma is a major cause of death for individuals under the age of 45 years and the third leading cause of death for all ages. So, it has been recognized as an important socioeconomic problem. The purpose of this study was to evaluate the outcome of surgical care of traumatized parients. METHODS: We retrospectively analyzed data of patients who had undergone surgical operation on head, abdomen, or chest trauma from January 1, 1995 to December 31, 1995. TRISS method and W- and Z- statistics were used to evaluate the trauma outcome and the quality assurance of surgical treatment. RESULTS: Two hundred and sixty eight patients were enrolled in this study. Traffic accident in injury mechanisms was the most common(n=185, 69.2%), and severely injured patients with over ISS 16 were 205 of total 268 patients(76.5%). Crude mortality rate was 11.6% (non-survivors/number of patients : 31/268). By TRISS method, predicted mortality rate was 10.1%, excess mortality rate was 14.2%, and W value was - 1.43 indicating less actual survivors than predicted, but absolute Z score was 0.91 and it was statistically not significant. CONCLUSION: These data show that trauma outcome and quality of surgical care in our hospital is adequate. We also suggest that it will provide a valuable data for further studies.
