Massive hemorrhage into an intracranial neurinoma is a rare event. A 42-year old man noticed hearing loss, nystagmus, diplopia and paresthesia on the left side of the face. A computerized tomography scan demonstrated a large high density mass in the left cerebellopontine angle. The tumor was successfully removed and postoperative course was favorable. Such a case of acoustic neurinoma which revealed itself through intratumoral hemorrhage has not been previously reported in Korea.

6 patients underwnet CT-guided stereotactic biopsy or hematoma aspiration procedure for posterior fossa lesions. Trajectory for biopsy or aspiration was transcerebellar approach. The patients were placed under general endotracheal anesthesia and positioned prone or sitting. No complications were encountered in the postoperative period when this technique was used. Stereotaxic transcerebellar multiple biopsy can safely provide tissue conformation of the neoplastic nature of a posterior fossa lesion thought to be a tumor. In addition, hematoma aspiration has been demonstrated to be safe, reliable, and efficient.

Authors experienced a case of acute myocardial infarction confirmed by analysis of LDH isoenzyme. 53-year-old male was admitted to Sacred Heat Hospital, Chung Ang University Because of severe precordial pain radiating to both arm, shoulder and back. Chest X-ray film & electrocardiogram were within normal limit and SGOT was 110 unit/ml on the day of admission. Determination of total LDH value and analysis of LDH isoenzyme by agar gel electrophoresis were made on the second hospital day. Total LDH was 315unit/ml, but there was significant increased percentage of LDH isoenzyme(LDH1). Electrocardiogram showed ST segment elevation only on the 8th hospital day.

Hip and knee replacement arthroplasty is one of the important causes of pulmonary embolism, of which the incidence was reported to be from 2 to 16% But, there are no reports about the incidence of pulmonary embolism after these operations in Korea. The authors' intention was to study the incidence and clinical manifestations of pulmonary embolism after hip and knee surgery. Lung perfusion scans and inhalation scans were done preoperatively and 7 days postoperatively for 139 hip or knee replacement arthrosplasty patients in Asan Medical Center. We studied 62 cases of avascular necrosis of the femoral head, 33 cases of femur neck fractures, 45 cases of degenerative arthritis of the hip and knee joints and 17 cases of other diseases. In this study, hip replacement arthroplasties were done in 114 cases, knee replacement arthrosplasties in 25 cases. On preoperative lung scan, high or intermediate probability findings of pulmonary embolism were shown in 18 cases and all of them were asymptomatic. 139 cases showed normal or low probability on preoperative lung scan, of which 5 cases were changed to high probability and 7 cases to intermediate probability on postoperative lung scan. Four of the 7 intermediate probability cases were confirmed to be pulmonary embolism on pulmonary angiography. Of these 9 cases, hip replacement arthroplasties were done in 6 cases and knee replacement arthroplasties in 3 cases. There were 5 cases of osteoarthritis of hip and knee, 3 cases of avascular necrosis of femoral head and 1 case of femoral neck fracture. We concluded that preoperative and postoperative incidences of pulmonary embolism in Korea were similar to those in western countires. Most of the pulmonary embolism patients were asymptomatic and so lung perfusion scans and inhalation scans were helpful in the early diagnosis of pulmonary embolism.

A retrospective analysis of the ultrasonographic findings of 9 cases of tuberculous abscess, 5 cases of pyogenic abscess and 2 cases of hematoma of psoas and adjacent muscles was made. Fluid collection with or without internal echoes was seen in 12 cases out of total 16 cases. Other findings were 2 cases of only muscle swelling, 1 case of highly echogenic mass.like appearance and 1 case of fluid collection with septae. Ultrasonography is considered an accurate method in identifying early pathologic changes of the psoas muscle and determining its extent. and in differentiating tumor from fluid collection of the psoas muscle. Authors dare to say that ultrasound examination is a procedure of choice in the diagnosis of psoas abscess and hematoma.

Osteoporosis is a major health-care problem for aging communities. And postmenopausal osteoporosis is a common disorder characterized by an increase in bone resorption relative to bone formation, generally in conjunction with an increased rate of bone turnover. Twenty female rats were used as rat model of osteoporosis. They randomly were divided into two groups: a normal control group, and calcium-free diet groups treated with bilateral ovariectomy. The animals were sacrified at 12 weeks after treatment. In the rats with osteoporosis, there was significant thining and loss of trabeculae, accompanied by a disconnection of trabeculae. And acid mucopolysaccharides were decreased in osteoporotic animals. In order to setup conditions of invivo micro-CT, proper anesthetic is ketamine (50 mg/kg) /xylazine (6 mg/kg). And proper breathing rate of experimental animals is 1.3~1.6/sec. Our finding suggest that bilateral ovariectomy and calcium-free diet induce decrease in thickeness of trabecular bone and decrease in acid mucopolysaccharide, therefore cause weakness of bone. And micro-CT imaging system is useful to evaluate trabecular bone. Anesthetic time, anesthetics and respiration rate also signify much in micro-CT imaging system.

The posterolateral approaches to the spine is an effective method for the neural decompression and the spinal stabilization. This procedure has an advantages of an one-stage posterolateral decompression-stabilization. We have experienced 8 patients with burst fracture in the thoracolumbar junction. A three-quater prone position was used for patient positioning. No patient showed neurologic deterioration after surgery. Patient positioning and the operative approach are described and illustrated.

Eosinophilic granuloma of the cervical spine is an uncommon disease. A 20-year old male patient noticed cervical pain, restricted range of movement, torticollis and tenderness. On computed tomographic scan, myelographic imaging and plain radiographic imaging demonstated a bony destruction in the left side of the third cervical vertebral body and a part of the pedicle. Preoperative radioisotope bone scan demonstrated an hot uptake in the third cervical vertebral body. Gross total removal of the lesion and radiation therapy were performed. Postoperative course was favorable. The lesion is readily curable and should be considered in the diferential diagnosis of pain or neurological deficit in association with a lytic defect in the cervical spine. Occasionally, a solitary lesion characteristic of eosinophillic granuloma in found in cases of otherwise classic Hand-Schuller-Christian. So, close chinical and radiologic follow-up sholuld be obtained.

In this transcultural comparison, we examined areas of stress, coping strategies and psychosomatic symptoms resulting from such strategies in Chinese, Korean-Chinese and Korean high school students. A total of 1,042 second-year high school students participated in this study: 213 Chinese from Yanbien, China: 368 Korean-Chinese from Yanbien, China ; and 466 Koreans from Seoul, Korea. We administered the Stress Questionnaire Form for High school Students(Won and Lee 995), the Ways of Coping-Revised(Lazarus and Folkman 1984) and the Physical Symptom Scale of Stress(Allen and Hyde 1980) to investigate areas of stress, coping strategies and psychosomatic symptoms, respectively. The findings were understood and interpreted from focus group discussions. Although there were no differences in total stress scores among the three groups, there were significant differences in areas of stress. Chinese students manifested the highest stress scores in peer relation, family problem, heterosexual problem, the future-employment, and religious problem. Koreans scored the highest in academic performance, school life, extracurricular activity, psychological-personality problem, value system, and the future-employment. The Korean-Chinese students scored the highest in extracurricular activity, family-economic problem. In terms of collectivism versus individualism, Chinese students' stress was related more toward the collective situation, whereas the Korean students faced increased stress regarding the individual situation. In coping strategies, the Chinese were characterized by active coping, Koreans by passive coping and the Korean-Chinese by a mixture of the two. Koreans had the highest scores in psychosomatic symptoms, suggesting unfavorable coping strategies. The Korean-Chinese students seemed to lie intermediate between Koreans and Chinese in all three study areas, implying their cultural pluralism.

Previous studies showed that whole body vibration could prevent bone resorption and stimulate new bone formation. The aim of this study is to detect and track effect of whole body vibration for osteoporotic bone of OVX rats. 12 Female rats were used and allocated into 5 group, CON, SHAM, WBV 17, WBV 30 and WBV 45. Rats except SHAM group were ovariectomised to induce osteoporosis. Rats in WBV groups were stimulated whole body vibration at magnitude of 1 mm(peak-peak) and frequency 17 Hz, 30 Hz and 45 Hz, repectively, for 8 weeks (20 min, 5 days/week). The 4th lumbar in rats were scanned at a resolution of 35 micrometer at baseline, before stimulation, and 8 weeks by In-vivo Micro-CT. To detect and track changes of morphological characteristics in lumbar trabecuar bone of rats, structural parameters were measured and calculated from acquiring images. In the results, changes of structural characteristics of WBV group were smaller than those of CON group. Loss of quantity of trabecular bone in WBV 45 was the least. In contrast, that in WBV 17 was the biggest. These results showed that reasonable whole body vibration beneficially affected osteoporotic bones. In addition to, whole body vibration was likely to be substituted partly for drug treatment.
