A case of Dariers disease was presented and the literatures were reviewed. The patient was 20 year old male whose skin lesions revealed normal skin colored, dirty, scaly, keratotic papules with mild itching on face, anterior chest, back, abdomen, axillae, groins and flexural surfaces of extremities. They had a tendency to aggrevate in summer and improve in winter. Histopathologically, suprabasal lacunae, hyperkeratosis, papiIIomatosis, moderate degree of acanthosis and corps ronds in Iacuna were demonstrated in the epidermis. Dermal papillae surrounded with single layer of basal cells proliferated inta the lacunae. Upper dermis revealed mild nonspecific inflammatory cell infiltrates.

Although the incidence of tuberculous arthritis of the hip is being decreased with improvement of hygiene and preventive measures and chemotheraphy, it remains as important disease in orthopedic surgery. In order to evaluate which treatment is best in the view of eradication of the tuberculosis and preservation of the function, seventy two patients of tuberculous arthritis of the hip who were treated at the Department of Orthopedic Surgery, Seoul University Hospital for periods of 14 years between January 1970 and August 1983 were analysed clinically. The results are as follows: 1. Age distribution showed that patients below 15 years were thirty (41.7%) and those above 16 years were forty two (58.3%). 2. Onset of the symptoms above 1 year occupied forty two patients (58.3%). 3. Duration of follow up is between 1 year and 14 years with average duration of 3.5 years. 4. Recurrence rate according to the modality of treatment was 12.9% as 4 cases among 31 cases of hip fusion group, 15,2% as 5 cases among 33 cases of synovectomy group, and 28.6% as 2 cases among 7 cases of conservative group. 5. Follow up of the functional evaluation of the hip was 92.9% of “above Fair” as 26 cases among 28 cases of synovectomy group, 60% of “above Fair” as 3 cases among 5 cases of conservetive treatment group, and 25.7% of “above Fair” as 9 cases among 35 cases of hip fusion group. 6. Although the recurrence rate of synovectomy group is a little higher than that of hip fusion group, synovectomy is a better treatment in the view of the preservation of the function of the hip considering Korean life style.

Total hip arthroplasty(THA) is applied to various hip diseases, and the results are different according to the disease entities. We have made the functional evaluation of three groups of the patients who had undergone THA in Seoul National University Hospital from 1981 to 1990: the first group-fused hips (28 hips of 27 patients), the second group partially ankylotic hips whose total range of motion were less than 60°(46 hips of 46 patients), and the third group-hips of ankylosing spondylitis (22 hips of 14 patients). The results were summerized as follows: No statistically significant difference was seen in the postoperative average Harris hip score between three groups. In the postoperative average range of motion, statistically significant difference was seen only between the first and second groups. Therefore, similar clinical results can be obtained from the THA in the fused hips to those of the partially ankylotic hips such as tuberculous or septic hip sequelae.

Since 1983, the transtrochanteric rotational osteotomy has been performed in 38 hips of 36 patients for the nontraumatic avascular necrosis of the femoral head at the department of orthopaedic surgery of Seoul National University Hospital. Out of them, 26 hips(18 cases of Sugioka grade I and 8 cases of Sugioka grade II ) were followed up for more than 1 year. The average period of follow-up was 3 years and 5 months(range, 1 year and 2 months to 7 years). These cases include 3 cases of failure before 2 years after operation. Overall, the result was satisfactory in 20 cases(77%)out of a total of 26 cases(success in 18 cases(69%)and good in 2 cases(8%)). The results of the grade I lesions(14 cases of success and 1 case of good result out of 18 cases) were better than those of the grade I lesions(4 cases of success and 1 case of good result out of 8 cases). Complications occurred in 5 cases. These include an ectopic ossification, a stress fracture of the neck, a nonunion of the osteotomy site, a nonunion of the greater trochanter and a delayed union of the greater trochanter. There were 6 cases of failure. For the 4 cases of them, hip replacement arthroplasy was performed. The MRI images axial to the longitudinal axis of the femoral neck gave excellent information for the operation.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated service requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation, hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with teh service diversification.

Demand for high quality medical care has recently been increasing in step with high level of income and education. Patients prefer the use of large general hospitals to small community hospitals. Large hospitals, usually located at urban area, expand their capacities to cope with the increasing demand, therefore, they easily secure revenue necessary for growth and development of hospitals. However, small community hospitals are facing with serious financial difficulties caused from the reduction of patients in one hand and the inflation of cost in another. If small rural hospitals were closed, the closure would have negative impacts on local economies in addition to the decrease in access to medical care. Community leaders should have an insight on the contribution of community hospitals to local economies. They could make a rational decision on the hospital closure only with the understanding of hospital's contribution to the community. This study is designed to develop an economic model to estimate the contribution of rural hospital to local economies, and also to apply this model with a specific hospital. The contribution of a hospital to local economies consists of two elements, direct effect and multiplier effects. The direct impacts include hospital's local purchasing power, employee's local purchasing power, and the consumption of patients coming from outside the community. The direct impact induces multiplication effect in the local economy. The seed money invested to other industries grows through economic activities in the economy. The seed money invested to other industries grows through economic activities in the region. This study estimated the direct effect with the data of expenditure of the case hospital. The total effect was calculated by multiplied the direct effect with a multiplier. The multiplier was drown from the ratio of marginal propensity of income and expenditure. Beside the estimation of the total impacts, the economic effect from the external resources was also analyzed by the use of the ratio of patients coming outside the region. The results are as follows. 1. The direct economic contribution of the hospital to the local economy is 1,104 million won. 2. The value of multiplier in the region is 2.976. 3. The total economic effect is 3,286 million won, and the multiplication effect is 2,182 million won. 4. The economic contribution from the external resources is 245 million won which is 7.5% of the total economic effect.
