BACKGROUND: Osteoporosis is an important and common medical problem in postmenopausal women. Depression is another major public health concern. Due to the high prevalence of both depression and osteoporosis, even a weak association between them might result in a greater health problem. We have investigated whether depression is associated with bone mineral density (BMD) in peri- and postmenopausal women. METHODS: The study subjects who visited the office of family medicine department and the health screening and diagnosis center in one general hospital from January to May, 2000 were selected. BMD was measured at the lumbar spine using Dual Energy X-ray Absorptiometry. We evaluated the depression scale using the Beck Depression Inventory. The subjects who had disorders known to interfere with bone metabolism or those who had taken medication related to depression were excluded from the study. RESULTS: Significant positive correlation were noted between BMD and height and weight (P<0.05) but no correlation was found with depression in perimenopausal women. In postmenopausal women, significant negative correlation was noted between BMD and age, and postmenopausal duration and depression. Significant positive correlation was found between BMD and height and weight (P<0.05). CONCLUSION: Our results showed that depression was associated with BMD in postmenopausal women which was independent of other factors strongly associated with osteoporosis.

PURPOSE: In this study, brazing characteristics of ZrO2 and Ti-6Al-4V brazed joints with increasing temperature were investigated. MATERIALS AND METHODS: The sample size of the ZrO2 was 3 mm x 3 mm x 3 mm (thickness), and Ti-6Al-4V was 10 mm (diameter) x 5 mm (thickness). The filler metal consisted of Ag-Cu-Sn-Ti was prepared in powder form. The brazing sample was heated in a vacuum furnace under 5 x 10(-6) torr atmosphere, while the brazing temperature was changed from 700 to 800degrees C for 30 min. RESULTS: The experimental results shows that brazed joint of ZrO2 and Ti-6Al-4V occurred at 700 - 800degrees C. Brazed joint consisted of Ag-rich matrix and Cu-rich phase. A Cu-Ti intermetallic compounds and a Ti-Sn-Cu-Ag alloy were produced along the Ti-6Al-4V bonded interface. Thickness of the reacted layer along the Ti-6Al-4V bonded interface was increased with brazing temperature. Defect ratios of ZrO2 and Ti-6Al-4V bonded interfaces decreased with brazing temperature. CONCLUSION: Thickness and defect ratio of brazed joints were decreased with increasing temperature. Zirconia was not wetting with filler metal, because the reaction between ZrO2 and Ti did not occur enough.

PURPOSE: Suicide attempts are known to be influenced by mass media reports. The purpose of this study was to evaluate the effects of mass media reporting celebrity suicides on an increase of intentional carbon monoxide (CO) poisoning and suicide attempts. METHODS: We retrospectively reviewed the medical records of the consecutive patients who presented with suicide attempts to the Emergency Department of Ajou University Hospital during a 24 month period. We obtained the demographic data, any past history of suicide attempt and the methods of suicide attempts from the medical records of the suicide attempters. Time series analysis was conducted for evaluating the influence of mass media reporting of celebrity suicide on the suicide rates. RESULTS: We finally enrolled 770 patients during the study period. The total number of suicide attempts by CO poisoning was 18 and the average number of suicide attempts by CO was 0.33+/-0.73 per week. All of the suicide attempts by CO poisoning occurred after a celebrity committed suicide using CO from burning charcoal. CONCLUSION: This study showed that celebrity suicide by CO poisoning resulted in the Werther effect, which made the rate of intended CO poisoning increase, and the study provided further evidence for the need to actively restrain mass media reporting of suicide to decrease the Werther effect.

Gastric bezoar has been known to occur occasionally in the gastrointestinal tract, as a result of foreign material accumulating in the stomach. Most case have been managed by surgical methods. Currently, the endoscopic mathod is after used for the gastrointestinal disease, and therefore we treated two cases of huge bezoars using the endoscopic polypectomy snare and lithotriptor. Subsequently, we are reporting these cases and have incorporated relevant literature which was reviewed for our report for the subject case.

Emergency Medicine is a medical specialty that provides comprehensive emergency care. The spectrum of emergency medicine includes humanity as well as medical care for emergency patients. Since the Korean Society of Emergency Medicine has been established and the training course for emergency residents has begun, quality improvement of the training course still remains to be one of the most important issues in emergency medicine. This report is to understand the current status of training of emergency residents and to improve the quality of training of emergency residents. The survey was performed with questionnaires regarding current status of training and opinions to improve quality of training. The questionnaires were sent to all emergency physicians and emergency residents registered to the Korean Society of Emergency Medicine via an electronic mail or a printed letter. The response rates were 49.6% for emergency physicians and 35.8% for emergency residents. On the basis of the result of this survey, we suggest five proposals for improving the quality of resident training course. These include complete adherence of each institution to training guidelines presented by the Korean Society of Emergency Medicine, development of the education program compatible to each institution, shortening of length of training duration from 4 years to 3 years, promotion of the training environment, and introduction of evaluation examination to the training course.

Anthracyclines have been widely used in cancer therapy because of their efficacy in the treatment of various solid tumors and hem -atologic malignancy. Cumulative dose-related cardiotoxicity was a well-known toxicity of anthracyclines. Particularly, at total doses of more than 550 mg/m2, therapy with anthracyclines could produce irreversible cardiac injury. Anthracycline-induced cardiac toxicity was usually manifested by congestive heart failure or arrhythmia. In co- ntrast, acute myocardial infarction is a rare event of anthracycline-induced heart diseases. A 31-year-old man with non-Hodgkin lymphoma(NHL) and single cardiac risk factor, including smoking, was presented with chest pain after receiving 2nd CEOP-BLAM chemo-therapy. An electrocardiogram revealed ST segment elevation in inferior leads consistent with acute myocardial infarction. An echocardiogram revealed an ejection fraction of 60% and severe hypokinesia in inferior and anteroseptal wall. Three days later, coronary angiography revealed 50% of luminal stenosis of right coronary artery(RCA) and near total occlusion with large thrombi in m-RCA. After balloon angioplasty and stent insertion, the patient was transferred to coronary care unit and continuous intravenous heparin infusion was started. On the 10th days, the patient was discharged in good condition. Six months later, follow-up coronary angiography showed no significant lesion in right coronary artery. In a young man with NHL, we report an acute myocardial infarction after 2nd course of CEOP-BLAM chemotherapy with a review of relevant literatures.

All-trans retinoic acid (ATRA) is the standard induction treatment for acute promyelocytic leukemia (APL). Quite many ATRA-related side effects, including retinoic acid syndrome, were reported. So far, it has rarely been reported that Sweet's syndrome, characterized by fever, neutrophilia, painful erythematous cutaneous plaques, dense dermal infiltrates of mature neutrophils and rapid response to steroid therapy, is associated with ATRA. In the case that Sweet's syndrome associated with ATRA is found, physicians will have to face a great challenge over the possibility of infectious conditions. We present here a case of Sweet's syndrome associated with ATRA. A 35-year-old female with APL developed fever, painful erythematous cutaneous plaques on both cheeks, right wrist and both shins during induction chemotherapy with ATRA. A skin biopsy revealed a dense dermal infiltrate, consisting of mature neutrophils without vasculitis or cutaneous immunoglobulin deposits, which is compatible with Sweet's syndrome. Oral prednisone was administered and the lesions started to improve within 48 hours

We describe the occurrence of acute type A aortic dissection in a patient with situs inversus totalis. A 37-year-old man presented to the emergency department with acute chest pain. Initial chest X-ray findings showed a right-sided heart and a left-sided liver. Contrast-enhanced computed tomography revealed a Stanford type A acute aortic dissection, aortic root dilatation, and situs inversus totalis. All of the thoracic structures were mirror-image reversed and an abnormal coronary artery was observed. The Bentall operation was performed. This report demonstrates that computed tomography and echocardiography were useful for understanding the anatomy and the presence or absence of concurrent anomalies in a patient with situs inversus totalis. The patient’s postoperative course was uneventful.
