The purpose of this study is to analyze degree of geographic maldistribution of physicians and changes in the distributional pattern in Korea over the years 1980-1985. In assessing the degree of distribution and in identifying changes in the distribution pattern, the Gini index of concentration was used. The geographical units selected for computation of the Gini index in this analysis are districts (Gu), cities (Si), and counties (Gun). Locational data for 1980 and 1985 were obtained from the population census data in the Economic Planning Board and regular reports of physicians in the Korean Medical Association. The rates of physician located countries to whole physicians were 10.4% in 1980 and 9.6% in 1985. In term of the ratio of physicians per 100,000 population, rural area had 9.18 physicians in 1980 and 12.95 in 1985, 7.13 general practitioner in 1980 and 7.29 in 1985, and 2.05 specialists in 1980 and 5.66 in 1985. Only specialists of general surgery and preventive medicine were distributed over 10% in county and distribution of every specialists except chest surgery in county increased in 1985, comparing with that rates of 1980. The Gini index computed to measure inequality of physician distribution in 1985 indicate as follows; physicians 0.3466, general practitioners 0.5479, and specialists 0.5092. But the Gini index for physicians and specialists fell -15.40% and -10.42% from 1980 to 1985, indication more even distribution. The changes in the Gini index over the period for specialists from 0.3639 to 0.4542 for districts, from 0.2510 to 0.1949 for cities, and 0.5303 for countries indicate distributional change of 24.81%, -22.35%, and 10.65% respectively. The Gini indices for specialists of neuro-surgery, chest surgery, plastic surgery, ophthalmology, tuberculosis, preventive medicine, and anatomical pathology in 1985 were higher than Gini indices in 1980.

Epithelioid hemangioendothelioma is a recently described vascular neoplasm characterized by epitheloiod endothelial linings and its borderline biologic behavior. We report a case of epithelioid hemangioendothelioma in a 6-year-old male. The tumor was presented as a non-tender dermal nodule on the left middle finger. The microscopic sections revealed irregular proliferation of vascular channels lined by epithelioid cells with histiocytoid features and frequent intracytoplasmic vacuoles, mimicking so called signet ring cells. Immunohistochemical stainings for factor VIII and vimentin were positive both in epithelioid and vacuolated endothelial cell. Electron microscopic finding reveals abundant intermediate filaments.

Growth acceleration following femoral shaft fracture occasionally results in a significant leg-length inequality with limp. The ability to predict subsequent overgrowth would enable the surgeon to compensate for growth acceleration by providing the appropriate overriding of the fragments before the time union. The purpose of this study was to establish principles which would aid in predicting over growth. Between 1972 May and 1983 September, 115 inward patients who were 16 years old or the younger were treated in the Department of Orthopaedic Surgery of Hanyang University Hospital. In these cases, we analysed the causes of fractures, associated injury and methods of treatment. And also, by use of mentgenogram, evaluated on site, shape and degree of overriding of fractures. And then, the degree of overgrowth of bone was compared with unaffected site and analized by Bell Tompson's split orthoroentgenogram. 1. The average tibial overgrowth after fracture of femoral shaft is 2.2 mm in length. 2. The average femoral overgrowth after fracture of femoral shaft is 9.4 mm in length.

Desmoplastic trichoepithelioma, a tumor of hair follicle, is usually seen as solitary lesions. Its clinical configuration is hard and annular, asympromatic, white or yellowish and varied in size from 3 to 8 mm, but the appearance of these lesion is not so distinctive to hair follicle tumors that the diagnosis is estabilished by the histopathologic findings. Microscopical findings of desmoplastic trichoepithelioma consist of narrow strands of tumor cells, horn cyst, desmoplastic stroma. We present here a case of desmoplastic trichoepitheliorna, which develops as 6 mm sised papule on the left cheek in a 57-year-old woman.

Wilms' tumor is the most common urinary tract neoplasm and one of the most frequent solid abdominal malignant tumors of childhood, usually diagnosed between the ages of 2 and 5 years. Typically, it is manifested as an asymptomatic unilateral or upper abdominal mass. Abdimonal pain after some traumatic incident, fever, anemia, hematuria and hypertension are other patterns of presentation. In a considerable number of these patients, pulmonary metastases are present at the time of primary diagnosis. But, the initial presentation of acute pulmonary tumor emboli without surgical manipulation is very rare. We describe a sudden unexpected infantile death case diagnosed as pulmonary tumor embolism preexisting Wilms tumor. To our knowledge, this is the initial autopsy presentation of Wilms tumor with tumor embolism as sudden and unexpected death in Korea.
