As the productive activities have vastly increased following industrialization and urbanization in the modem society, the resulting high mobility of people and goods have caused a sharp increase in the accidents in the work places as well as traffic accidents. In particular, deaths caused by injuries are generally concentrated in the economically active young peoples, producing incalculable losses to the society and nation as a whole. Advanced nations with superior medical care systems have succeeded in reducing incidents of such deaths by operating trauma centers. Especially noteworthy is the case of the United States where such specialized trauma centers have greatly contributed to reducing deaths from injuries in the non-urban areas with less access to medical facilities. At present Korea has no medical centers specializing in injuries. In large cities, the injuries are being treated tertiary medical facilities while in the provinces they are referred to small and medium-sized hospitals that constitute secondary medical facilities. Currently in Korea the Trauma patients are treated at general hospitals that consist of 726 secondary medical facilities and 40 tertiary medical centers nationwide. The secondary medical facilities which tend to take most responsibility for the treatment of trauma are generally deficient in medical staff and facilities (including operating and intensive care facilities). Despite such deficiency and limitations, no regulations exist regarding treatment or transportation of trauma patients. This article reports the outcome of a comparative analysis of the results of trauma treatments among different types of medical facilities based on objective data in the hope that such study would facilitate a comparison with the treatment systems of advanced countries and thereby contribute to a precise formulation of problems that must be addressed in this area.

There have been many reports on cerebrovascular disease in Korea, almost all of which were done at the Department of Neurosurgery, Neurology, and Internal Medicine. It is established that hemorrhagic stroke(HS) occurs at a higher rate than ischemic stroke(IS) compared to Western societies. However, many patients with IS visit to Oriental Medicine in Korea. Because of the paucity of published information including stroke data of Oriental Medicine, it was our purpose to analyse characteristic pattern of stroke occurrence, clinical data, and outcome for 762 patients visited to emergency room or admitted to the University Hospital and Oriental Medicine for a twelve month period. The incidence of IS was at least 1.5 times that of HS(IS: 309, HS: 453). Among age groups, those in sixties and seventies were the most predominant. The distribution of patients according to each Departments and Oriental Medicine was 118(HS: 2, IS: 116) in Department of Internal Medicine, 286(HS: 251, IS: 35) in Neurosurgery, and 358(HS: 56, IS: 302) in Oriental Medicine. The overall outcome for HS are much poorer than those for IS: in HS, 69.6% good, 10.7% morbidity, and 19.7% mortality, and in IS, 83.2%, 13.0% and 3.8%, respectively. Considering the fact that many IS patients with mild symptoms and signs tend to visit private clinics, these results suggest the actual incidence of Is is much higher than HS in Korea, compared with previous reports. We expect that a multicentered cooperative study including Oriental Medicine will be motivated by this study for establishing more accurate characteristics of stroke in Korea in the future.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.

We report a case of dedifferentiated liposarcoma of retroperitoneum as a recurrent form in a 41 year old male. The patient received a extirpation for retroperitoneal mass and diagnosed as myxoid liosarcoma 4 years ago. The patient experienced 3 recurrences over a period of 4 years and diagnosed as myxoid liposarcoma in the second, third recurrence also. Histologically, the mass was composed of several clearly distinct elements : well differentiated liposarcoma, myxoid liposarcoma, myxoid malignant fibrous histiocytoma, poorly differntiated sarcoma, and fibrosarcoma. Immunohistochemically, S-100 protein was expressed in the area of spindle cell sarcoma, well differentiated liposarcoma, and malignant fibrous histiocytoma but alpha-1-antichymotrypsin was only expressed in the area of myxoid malignant fibrous histiocytoma.

We have reported general principles of low vision aid prescription. But, we have not reported near vision aid prescription only. So, we analyse prescriptions of near low vision aid(diagnosis, type, magnification, etc) and present new near low vision aids that patients feels comfortable. We reviewed the clinical records of 100 patients who visited our low vision clinic more than twice and was prescribed near low vision aid for low vision. According to the data analysed, optic nerve atrophy was the most common etiology for low vision. Illuminated hand held magnifier(31.3%), telemicroscope with plus cap(27.7%), aspheric doublet sens(Clear Image II)(24.1%) were low vision aids most commonly used for near vision, but we knew new trend that newly prescribed aids(telemicroscope with plus cap, aspheric doublet lens) were prescribed more than illuminated hand held magnifier. After prescription of the low vision aid, visual acuity improved significantly (p<0.05). We examined contrast sensitivity test to measure the functional acuity and predict the visual prognosis after prescription of low visio aid.In addition,we studied the relationship between reading speed and the degree of contrast sensitivity and we knew that the relationship between degree of contrast sensitivity and reading speed was associated(p<0.05). Majority of patients(89%) were benefited from prescribed low vision aids.
