BACKGROUND: The mental problems of the elderly are at issue as a serious social phenomenon. The purpose of this study is to identify risk factors affecting the mood disorders of the elderly. METHODS: The subjects were 1,779,236 aged ≥65 and participated in health screening. Dependent variable was mood disorders. Independent variables were consisted of community level (regional deprivation index and healthcare resources) and individual level (sex, age, insurance type, disability, smoking, alcohol, physical activity, body mass index, and healthcare utilization). Multilevel logistic regression was performed. RESULTS: At the individual level, women, employed insured, severely disabled people, heavy alcohol drinkers, high-intensity physical activity, body mass index, and patients who had chronic disease and severe disease were significantly associated with mood disorders. As the age has increased, it has let increase of mood disorders. At the community level, as the regional deprivation index has increased by 1, mood disorders has been increased by 1.005 times. The intra-class coefficient was 7.04%. CONCLUSION: We found individual and community level factors are associated with mood disorders. Systematic approach is essential to reduce mood disorders.

It has recently become possible to record electrical activity originationg from abnormally conducting myocardium from the body surface with high-gain amplification and averaging technique. These signals, which result from delayed ventricular activation(late potentials), have been recorded in patients with documented ventricular tachyarrythmia. Several electrode lead system for detecting ventricular late potential were introduced. Pyramidal electrode lead system(PLS) is useful. Also interpretation of SAECG in the young could be of value in detecting those at risk for episodic ventricular tachycardia, but suffer from a lack of data in normal young people. There was no difference between normal values, determined by FLS and PLS at high pass filtering of 25 Hz and 80 Hz, but significant, difference was found in HFLAD and RMS-40 of 40 Hz (p<0.05). These results will provide a basis for interpretations of SAECG, determined by FLS and PLS in healthy young adults with normal QRS duration. SELECTION OF SUBJECTS: For this study, normal healthy young adult volunteers (age : mean 24 years) were recruited from the medical students at Yeungnam University Hospital, Internal Medicine. Twenty fourths male and seventeenths female subjects were selected. All subjects had normal resting ECGs as judged from both the standard 12 channel lead and echocardiography, and none had a history of cardiovascular disease. All subjects were considered to be in good general physical condition. SIGNAL-AVERAGED ELECTROCARDIOGRAPHY: In order to obtain low noise recordings with a small number of averaging cycles, all subject ware asked to relax completely in the supine position. Silver/silver chloride electrodes were attached after the skin was cleaned with alcohol, to constitute classic flank lead system(FLS) and pyramidal lead system(PLS). Signals were recorded and processed using a commercially available microprocessor-augmented ECG cart(Marquette Electronics, USA) suitable for portable bedside recording.

PURPOSE: We aimed to know the prevalence of abnormal meniscal signal on MR imaging in asymptomatic soccer players and its radiologic significance. MATERIALS AND METHODS: Using T1 and gradient echo T2* weighted sagittal and coronal MR image, 48 knees in twenty-four full time soccer players were evaluated for the meniscal abnormalities, the status of ligament and existance of joint effusion. Meniscal abnormalities were interpretated using grading system of Lotysch. By using Chi-square method, We analyzed the existance of joint effusion could divide the healing state and healed state of the meniscus. RESULTS: The prevalence of Grade 2 and more and Grade 3 were 42% and 39% of asymptomatic knees. In the 24 knees with meniscus tear, nine of the 14 asymptomatic knee showed effusion while eight of the 10 symptomatic knee did. Of 24 knees with meniscal tear, only eleven knees were related to previous history of major knee trauma. CONCLUSIONS: The prevalence of meniscal abnormalities on MR imaging in asymptomatic soccer players was higher(grade 3:39%) than we expected. The joint effusion was not helpful to divide the healing state and healed state of the meniscus. So we suggest baseline MR imaging in the athletes who have been using the knee vigorously could give decisive information for the interpretation of subsequent MRI that may be performed when the players wounded.

So-called Brunners gland adenoma is characterized by a nodular proliferation of histologically normal Brunners gland, accompanied hy duots and scattered stromal elements. This benign tumor of the duodenum is rare and is not eaey to discover because of non-specific symptoms. The clinical presentation can vary from vague upper abdominal symptoms with dyspepsia and nausea to diarrhea, jaundice, obetruction and gastrointestinal bleeding. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The management of Brunners gland adenoma is complete removal of the lesion and pathologic examination, always necessary to define the nature of the lesion and exclude malignacy. We experienced two cases of Brunner's gland adenoma in the duodenal bulb. The patients complained of epigastric discomfort and bloating respectively. The endoscopic examination revealed round semipedunculated polypoid mass covered with normal muosa at duodenal bulb. One case with a small adenoma (size: 0.7 x 0.7 cn) had been removed by endoscopic polypectomy and the other case with a relatively large polyp (aize: 2.0x2.0cm) had been treaed by transduodenal exploration and excision of the polyp.

BACKGROUND AND OBJECTIVES: Carotid artery stenting has evolved as a potential alternative to carotid endarterectomy in patients (pts) with significant carotid artery stenosis. We evaluated the feasibility and long-term outcome of carotid artery stenting in selected pts at high surgical risk. MATERIALS AND METHODS: Between May, 1996 and September 1998 we performed carotid artery stenting at 35 lesions in 25 pts. There were 23 males and 2 fe-males. Mean age was 63.2+/-6.6 (range 54 - 77). Eight four percent (21/25) of the pts had significant coronary artery disease. Sixty four percent (16/25) of the pts had significant peripheral artery lesions. Sixty percent (15/25) of the pts had neurologic symptoms or non-disabling stroke. We used Wallstent in 32 lesions and Palmaz stent in 3 lesions. Carotid stenting was undertaken in 33 internal carotid, 1 common carotid and 1 external carotid lesions. Bil-ateral carotid stenting was undertaken in forty percent (10/25) of the pts. RESULTS: Carotid stenting was successful in all lesions. One patient died due to massive cerebral hemorrhage 3 days after carotid stenting, who had und-erwent stenting as a rescue procedure for failed endarterectomy. One major stroke developed during procedure with partial recovery. For the combined endpoint of strokes and death within 30 days of procedure, the incidence was 8% and 5.7% in terms of pts and procedures, respectively. On follow-up (12+/-7 months), we found neither neurologic complications nor death. Angiographic and/or duplex sonography which were performed at 5.5 month in all (18) eligible pts with 24 lesions revealed no evidence of stent deformity or restenosis ( 50% of diameter stenosis). Mean angiographic stenosis was 20% on follow-up angiography. CONCLUSION: Carotid artery stenting can be performed with high success and low complication rate in pts with significant carotid artery stenosis especially at high surgical risk. Follow-up clinical outcome of average 12 month was good with low restenosis rate.

Inflammatory fibroid polyp is a relatively rare, benign polyp which is composed of fibraus connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflammatory fibroid polyps has been reported with pathologic specimen in stomach and small intestine. We performed the gastrofiberscopy and endoscopic ultrasonogram of an inflammatory fibroid polyp, which reveals central ulcerated polypoid mass originated in the submucosa of antral portion of the stomach. So we report a case of endoscopic and endoscopic ultrasonographic findings of inflammatory fibroid piolyp in stomach. The etiolagy and pathology are discussed with the review of the literatures.

We present the multidetector CT findings with a pathologic correlation for the case of a solitary fibrous tumor located in the trachea. The MDCT revealed a well-circumscribed intraluminal mass arising from the trachea, with strong nodular enhancement in the periphery of the mass. The enhancement pattern of the mass corresponded histopathologically to a focal hypocellular area in the center and prominent blood vessels along the periphery of the mass. We also present volume-rendered and virtual bronchoscopic images of this rare submucosal tracheal tumor.

A clinical review of 34 cases of aortic dissection which were admitted to Yeungnam University hospital between March 1983 and April 1992. The results are as follows: 1. The peak incidence was in 5th, 6th decade and male to female ratio was 1.83:1. 2. The most common cause of aortic dissection was atherosclerosis and hypertension (79%). 3. The most common presenting symptom was pain (73%). but dyspnea, palpable mass, murmur, shock were also observed. 4. Abnormal electrocardiographic finding was myocardial ischemia in 6 cases, arrhythmia in 5 cases, LVH in 5 cases. 5. The X-ray findings showed abnormal aortic contour in 10 cases but normal X-ray finding was observed in 63% of DeBaKey Type III. 6. The most common diagnostic procedure was echocardiogram and abdominal Ultrasonography. 7. The mortality of all cases was 20%, operation mortality was 18% but no death of medically treatment in medical indication.
