Injuries are serious problem common to all societies. Yet even within a single community, groups of injured persons differ as to the nature and severity of their injuries. The difficulty of adjusting for such variations has hampered scientific study of injured persons. Neverthless it is essential to take differences in severity of injury into account when comparing the morhidity & mortality of various groups for the purpose of evaluating their emergency & subsequent care. In order to provide the guidelines of mass emergency care & transportation, the authors analysed the 206 injured patients of train accident at Kyungsan, May 14th, 1981 and compared mortality with severity and body system of the injuries. The results were obtained as follows: l. Of 206 injured patients, most were young people & the ratio of male & female was about equal. 2. Extremities were the most frequently injured parts of body system & single injury was more common. 3. According to most severe injury of AIS, 78% of injured persons belonged to below AIS grade 3 and none was dead. 4. Average ISS of survival groups was 6 and that of death groups was 34. None was dead below average ISS of 15. 5. Death rate was higher for patients above 50 years of age, than that for young patients and there was no age difference in mortality for ISS of 50 and higher. 6. Majority of death group were invclved in multiple injuries and major cause of death were chest and head injuries. 7. Average ISS and age of hospital death group were less than those of DOA group. 8. The authors thought that it was necessary to estahlish Emergency Service System including training and education of both professionals and the pulic, hospital categorization, communication and transportation system for the mass emergency care.

PURPOSE: To evaluate the radiologic manifestations of the rectal leiomyosarcoma. MATERIALS AND METHODS: We reviewed CT and barium study of 2 cases of rectal leiomyosarcoma, which were operated and pathologically proved. RESULTS: In both cases colon studies showed a huge smooth marginated filling defect in the rectum. Precontrast CT scans showed a well-circumscribed, slightly Iobulated, inhomogeneous mass without calcification. Postcontrast scans showed minimal enhancement with internal low-density areas. In pathologic specimens there were large areas of necrosis and hemorrhage in the masses. Pericolic fat infiltration, lymph node metastasis, or distant metastasis were not detected. CONCLUSION: Leiomyosarcoma is rarely developed in the rectum, but general radiologic findings are similar to that of other part of the gastrointestinal tracts except for the tendency of intraluminal growth due to narrow pelvic space.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

Aneurysm*

Since 1960s, when Ross and Barratt-Boyes introduced homograft replacement of the aortic valve, the valvular replacement using homografts or autografts has been gained increasing acceptance. Aortic or pulmonary valves (with or without associated vascular conduits) transplanted from one individual to another have exceptionally good hemodynamic profiles, a low incidence of thromboembolic complications without chronic anticoagulation, and a low re-infection rate following valve replacement for endocarditis. The homografts were primarily used for complex congenital reconstructions in infants, and children. However, more recently they have been increasingly used in adults requiring aortic valve replacement. Even though there are many advantages, the lack of available homografts, as well as concerns of long-term stenotic problems, may limit their use.
