Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

A 62-year-old man presented with a tender, solitary nodule on the left upper arm. He had no specific family history of the lesion. A biopsy specimen showed various sized irregular vascular lumens in the upper dermis. The vascular walls consisted of an endothelial cell layer and rim of one to three layers of glomus cell nests outside the endothelial cells. The cell nests consisted of round shaped epitheloid cells with relatively uniform round or oval shaped nuclei and pale cytoplasm. These tumor cells were strongly positive for vimentin, and a-smooth muscle actin. On electron microscopic examination, the cytoplasm of these tumor cells contained fine filamentous components and many electron dense bodies were found at the plasma membrane and the cytoplasm. We report a case of a solitary glomus tumor(glomangioma) that showed the histological features of the multiple type of glomus tumor. In addition we describe the results of an immunohistochemical and electron microscopic study.

Malignant germ cell tumors occur in children and young women in reproductive age, of all the germ cell malignancies, only pure dysgerminomas had a high cure rate prior to 1970. This was due to the exquisite radiosensitivity of these tumors. Multiple-agent chemotherapy has dramatically improved the pmgnosis of patients with malignant ovarian germ cell tumors. Clinicopathological analysis was performed on 21 cases of malignant germ cell tumors of the ovary, 9 cases at the department of Obstetrics & Gynecology, Kyung-pook National University Hospital, 4 cases, at the department of Obstetrics and Gynecology, Dong-guk University Kyungju Hospital and 8 cases, at the department of Obstetrics and Gynecology, Dae-gu Fatima Hospital during the period 10 years from July. 19S8 to June. 1997 The results were summarized as follows: 1. The mean age of the patients was 21.8 years old, ranging from 10 to 61 years old. 2. Main initial symptoms were abdominal distension(33.3%), abdominal mass palpation(33.3%), abdominal pain(28.6%), amenorrhea(4.8%) in order. 3. Histologically, the tumors were classified as immature teratoma(57.1%), dysgerminoma(19%), mixed germ cell tumor(9.5%), endodermal sinus tumor(9.5%), embryonal cell carcinoma(4.8%). 4, According to FIGO classification Stage I was the most prevalent(57.1%) at the time of diagnosis while Stage III was forward in 48.6%, Stage II in 9.5%, and no Stage IV, 5. The 5-year survival rate was 80.4% and three patients have died of malignancy and the other 18 patients live without disease from 11 to 102 months, with a median follow-up of 34.2 months. 6. Prognostic factors of malignant germ cell tumors in this study were the clinical stage, the presence of ascites and the residual tumor mass.

PURPOSE: We investigated whether myocardial SPECT had additional usefulness to clinical, functional or surgical indices for the preoperative evaluation of cardiac risks in noncardiac surgery. MATERIALS AND METHODS: 118 patients (M: F=66:52, 62.7+/-10.5 years) were studied retrospectively. Eighteen underwent vascular surgeries and 100 nonvascular surgeries. Rest T1-201/stress Tc-99m-MIBI SPECT was performed before operation and cardiac events (hard event: cardiac death and myocardial infarction; soft event: ischemic ECG change, congestive heart failure and unstable angina) were surveyed through perioperative periods (14.6+/-5.6 days). Clinical risk indices, functional capacity, surgery procedures and SPECT findings were tested for their predictive values of perioperative cardiac events. RESULTS: Peri-operative cardiac events occurred in 25 patients (3 hard events and 22 soft events). Clinical risk indices, surgical procedure risks and SPECT findings but functional capacity were predictive of cardiac events. Reversible perfusion decrease was a better predictor than persistent decrease. Multivariate analysis sorted` out surgical procedure risk (p=0.0018) and SPECT findings (p=0.0001) as significant risk factors. SPECT could re-stratify perioperative cardiac risks in patients ranked with surgical procedures. CONCLUSION:: We conclude that myocardial SPECT provides additional predictive value to surgical type risks as well as clinical indexes or functional capacity for the prediction of preoperative cardiac events in noncardiac surgery.
