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.

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.

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.

This study was designed to investigate factors relating to fiscal deficit for regional health insurance. The financial statements for the fiscal year 1990 of nationwide 254 regional medical insurance societies were analyzed. Important findings are summarized below: 1. There were differences in the main reason for the financial deficit among regions when deficit and surplus societies were compared by regions. The total revenue per enrollee, especially revenue from the premium contribution of a deficit society was significantly smaller than that of a surplus society in large cities and counties. On the other hand, the total expenditure per enrollee of a deficit society was larger than that of a surplus society in small cities. 2. Both low premium irate at the beginning of health insurance program and less effort to increase the premium rate were main factors for the smaller revenue from the contribution of a deficit society in large cities and counties. 3. Larger expenditures per covered person of a deficit society in small cities were explained with larger medical expenditures especially for out-patients services rather than larger administrative expenses. 4. A regression analysis showed that utilization rates in out-patient services were significantly associated with income and numbers of total medical care institution per capita within a region where a health insurance society located. Also expenses paid by insurer per visit were associated with the proportion of utilization for tertiary care hospitals as well as the proportion of utilization of public health centers.
