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.

Small ovarian cysts(<0.7 cm in diameter) are common in prepubertal children. Occasionally larger cysts occur in young girls with isosexual incomplete precocious puberty in the absence of LH and FSH elevation. The mechanism of production of these autonomous functioning cysts is unknown. A 3 year 6 month-old girl was referred to our department of pediatrics because of severe vaginal bleeding. On examination, she was tall and had breast enlargement of Tanner stage II. On hormonal study, FSH(0.38mIU/ml) was suppressed and estradiol(62.2pg/ml) was markedly elevated, and GnRH stimulation failed to evoke an increase in gonadotropin. Bone age was advanced. Pelvic ultrasonography showed both huge ovarian cysts. Brain MRI showed no abnormalities. We underwent both ovarian cystectomy and histological examination showed follicular cyst in left ovary and luteal cyst in right ovary. After ovarian cystectomy vaginal bleeding stopped and hormonal abnormalities were normalized. We report a case of autonomous ovarian cysts presenting severe vaginal bleeding treated with ovarian cystectomy.

Malignant neuroepithelioma is a rare neoplasm arising within the peripheral nervous system and usually occurs in the lower extremities. It may involve patients in any age group and have no gender predisposition. In adolescents and adults the tumor must be distinguished from other malignant round-cell tumors. The poor prognosis and the need for aggressive, combined surgical and chemotherapeutic modalities in treating this tumor necessitate a prompt and accurate diagnosis. Authors have experienced a case of malignant neuroepithelioma developed in left sciatic nerve. The diagnosis was confirmed by CT scan, M.R.I., light and electron microscopic findings.

The management of supracondylar fractures of the femur remains controversial. Most studies over the past twenty years have attempted to compare the results of non-surgical with those of surgical methods. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur. However, the development of new fixation devices and techniques have, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 96 cases of supracondylar fractures of the femur treated in the Department of Orthopedic Surgery, Yonsei University, College of Medicine during the past 10 years from Jan. 1971 to Dec. 1980. 1. The prevalent age distribution was between 21 and 50 years of age (79.1%), and the ratio between males and females was 3.4:1. The most common cause of injury was car accidents (51.0%). 2. A classification of supracondylar fractures was unicondylar, simple supracondylar and intercondylar. Intercondylar which was subdivided into Type I, II-A, II-B, III according to Neer's classification. 3. Fifty nine patients (61.4%) were associated with injuries of other parts and the most frequent associated fracture was tibial fracture and the most common associated soft tissue injury was cerebral concussion or contusion. 4. The methods of treatment: conservative management by using skeletal traction for 34 cases, surgical treatment by open reduction and internal fixation for 58 cases and A-K amputation for 4 cases due to populiteral artery injury. 5. Fifty nine cases were suitable for result analysis. The satisfactory result of surgical treatment was 63.4% and conservative treatment was 50.0% respectively. The factors affecting the final results were Type of fracture, severity of injury, and rigid internal fixation. 6. The main complications of the supracondylar fractures of the femur were delayed union (10.2%), infection (10.2%), and traumatic arthritis (13.3%). 7. Finally, the results of treatment depend largely on anatomical reduction, rigid fixation, early joint motion.

The femur is the largest long bone in the body which is related to weight bearing. As a result of rapid increase in traffic accidents and industrial injuries, the incidence of femoral shaft fractures has risen also. The methods of treatment in children and adults are different, therefore inadequate treatment can cause permanent disability. The authors have reviewed 211 cases of femoral shaft fractures in 204 persons (children and adults) from September 1967 to September 1976 whe were admitted and treated in Orthopedic Department, Severance Hospital. The results were as follows: 1. The fractures occured commonly in the 6–10 yr. age group (41.2%) in children and in the 21–40 yr. group (54.2%) in adults. Males comprised 138 cases (67.6%). 2. Closed fractures were 185 cases (87.7%) and comminuted fractures were the most common type, 94 cases (44.5%) in all. The fracture site was middle third in 116 cases (55%). 3. Causes were mainly car accidents, 146 cases (71.5%) and industrial injuries. Pedestrian injuries are particularly common in Korea. Many industrial accidents occur due to inadequate working facilities in factories. 4. Associated injuries were common in young adults and in order of frequency these were fractures of the tibia and fibula; skulls; pubic bone. 5. In the early and delayed operation groups, primary bony union rate was better (92%) in the early than the late operation group (78.3%). 6 The period of bony union was 13 weeks with compression plate and screw fixation: 16 weeks with Kuntscher nailing; 17. 5 weeks with plate and screw fixation; and 20 weeks with skeletal traction in adults. 7. Knee joint motion was most limited with skeletal traction (33.5%), less with plate and screw fixation (14.7%) and Kuntscher nailing (1.7%), but none with compression plate and screw fixation. 8. Good results were obtained with conservative treatment in children and operative treatment in adults. 9. Complications were much less frequent in children than in adults and were treated well. 10. Post-operative infection rate was 4.4% and infection was treated well with conservative measures. 11. The 90° – 90° skeletal traction in children and compression plate and screw fixation along with cast brace in adults were recommended.
