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.

There are increasing interest and need for information on health care consumer with the significance of hospital marketing and strategic planning being increasingly emphasized. This study was conducted to investigate the criteria for selection of medical facilities according to the characteristics of health care consumer by the types of medical services on a sample of 1,500 population aged 20 years and above. Major findings are as follows; 1. When considering the criteria for selection of medical facilities into two factors, namely, quality or convenience factors, convenience factor was the major contributor for outpatient and dental services whereas it was quality factor for inpatient services. 2. Females and those residing in large cities selected medical facilities based on convenience factor in the outpatient services. In the case of inpatient service, persons who considered their present health status to be good and whose ages were 50 years old and above choose medical facilities based on quality factor. 3. Persons who considered medical facilities to be profit-making tended to choose medical facilities based on convenience factor for outpatient services. There were no differences in the cases of inpatient and dental services. 4. There was no significant difference on the criteria for selection of medical facilities according to the decision maker for selection or trust on medical facilities. On the use of health service information, selection of medical facilities was based on qPality factor for those who made more use of the information in the cases of outpatient and dental services. 5. Analysis using the logistic regression model on the criteria for the selection of medical facilities with the characteristics of health care consumer as independent variables was performed. The selection of medical facilities was significantly related with residential area, sex, and use of information on medical facilities for outpatient services and with age, average monthly income, and perception of health status for inpatient services. For dental services significant association with residential area and use of information on medical facilities was seen. The results of this study, despite some limitations, can be used as baseline data for marketing and strategic planning of hospital management.

The congenital ball-and-socket ankle joint is a rare condition and is associated with congenital shortening of the lower extrimity and various skeletal abnormalities of the foot. This disease entity was reported in the German literature by Politzer in 1931 and in the English literature by Lamb in 1958. Several series have been reported since, suggesting that the condition may not be as rare as generally thought. This case is, to our knowledge, the first reported in this country.

A clinical observation was made on the 236 patients who had undergone transurethral resection of bladder tumor(TUR) between Jan. 1990. and Feb. 1996. in the Department of Urology, Korea Cancer Center focusing on complications. The mean operating time was 59.0 minutes(n=400). The most common immediate complication was bleeding(1.8%), and the remainder was nonurologic fever(0.8%). The delayed complication was urethral stricture(1.0%) requiting visual urethrotomy. The immediate postoperative morbidity was 2.5% and risk factors for immediate morbidity after TUR were operating time longer than 60 minutes and tumor, invading the muscle or more deeply(p<0.05, by Chi-square test). The delayed morbidity was 1. 0% and the only risk factor for delayed morbidity after TUR was the number of ~IJR more than 2(p<0.05, by Chi-square test). Careful attention to surgical details and indications is needed to reduce the amount and significance of the postoperative morbidity.

Total cystectomy was performed to the 40 patients with urinary bladder tumor who were found perivesical fat infiltration by computerized tomography. 25 patients were previously untreated, and 15 patients had undergone transurethral resection or biopsy of the tumor before computerized tomography. The histopathological stage was compared to the preoperative computerized tomography stage. In pathologic specimen, perivesical fat infiltration was found in 62.5% of the cases, whereas perivesical fat infiltration was not found in 37.5% of the cases. In untouched tumors or after transurethral resection computerized tomography accuracy demonstrated no significant difference.

BACKGROUND: Flecainide is an antiarrhythmic agent that is used primarily in the treatment of cardiac arrhythmias. Some evidences also suggest that flecainide can participate in alveolar fluid clearance and inflammatory responses. This experiment was aimed to evaluate the effects of flecainide on sepsis induced acute lung injury in a rat model. METHODS: Rats were treated with subcutaneous infusion of saline or flecainide (0.1 or 0.2 mg/kg/hr) by a mini-osmotic pump. Subcutaneous infusion was started 3 hours before and continued until 8 hours after intraperitoneal injection of saline or endotoxin. Animals were sacrificed for analyses of severity of acute lung injury with wet to dry (W/D) ratio and lung injury score (LIS) in lung and inflammatory responses with level of leukocyte, polymorphonuclear neutrophils (PMNs) and inteleukin-8 (IL-8) in bronchoalveolar lavages fluid (BALF). RESULTS: Flecainide markedly improved dose dependently sepsis induced acute lung injury as analysed by W/D ratio (from 2.24 ± 0.11 to 1.76 ± 0.09, p < 0.05) and LIS (from 3 to 1, p < 0.05), and inflammatory response as determined by leukocyte (from 443 ± 127 to 229 ± 95, p < 0.05), PMNs (from 41.43 ± 17.63 to 2.43 ± 2.61, p < 0.05) and IL-8 (from 95.00 ± 15.28 to 40.00 ± 10.21, p < 0.05) in BALF. CONCLUSIONS: Flecanide improve sepsis induced acute lung injury in rats by controlling inflammatory responses.
