The application of personal computer (PC) to manage urologic patient data is now popular in many institutes. many users were accustomed to the IBM PC and familiar with the dBASE program in managing urologic records. But in recent days, the number of Macintosh PC users are increasing because it is easy to learn and perform Macintosh which provides the excellent output under the given input data. We developed the patient management system with Excel program in Macintosh PC focusing on minimizing the effort to input the data and maximizing the output. The data fields consist of eight fields. They are chart number. name. sex. date of admission data of discharge. diagnosis and international classification of diseases. There is no need of typing the international classification of diseases because it is automatically registered by previous coding with diagnosis. We think that the application of international classification of diseases is essential to minimize the input errors. The output of data include sex ratio and variable statistics. which ere provided with graphic mode. Another output is the extract of data under the variable criteria. which are provided with worksheet mode.

Masson's hemangioma is a rare benign vascualr condition with a papillary intravascular endothelial proliferation which may appear either as aprimary form or as a secondary form in a pre-existing vascular process.CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were locatedextra-axially in the posterior fossa. CT findings were not specific in both cases: One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiolocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast mediawhich were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in theposterior fossa is discussed.

PURPOSE: Some recent studies have demonstrated that finasteride, a well- known 5alpha-reductase inhibitor, can decrease prostate specific antigen (PSA) by approximately 50% during the first 1 year of treatment. We investigated how long-term treatment with finasteride and alpha-blockers impacts on the serum PSA level of men whose final diagnosis was benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: In a retrospective trial, we evaluated a total of 293 men with lower urinary tract symptoms (LUTS) that were suggestive of BPH. These men were divided into two treatment groups: group A was treated with alpha-blockers and group C was treated with a combination of finasteride and alpha-blocker. Comparisons of the two groups were performed by using independent t-tests. The changes in the PSA concentrations from baseline to the time of the final measurements were determined by repeated measures of ANOVA. RESULTS: There was no significant difference in the baseline PSA between the two groups. A statistically significant reduction in the PSA levels was observed at 2 years in C group (p<0.05), whereas any significant increase were not observed in group A (p>0.05). In group A, the repeatedly measured PSA levels were 2.67, 2.40, 2.41 and 2.42, respectively. In C group, these were 3.22, 2.09, 1.81 and 1.71 respectively. CONCLUSIONS: Our data showed that there was no clinically significant effect of long term treatment with alpha-blocker on the PSA levels. However, finasteride had significant effect on the serum PSA level during first two years of treatment.

Upper gastrointestinal(UGI) bleeding was critical disease that was commonly found in emergency department and needed more early diagnosis and rapid treatment for decreasing mortality and morbidity. It's causes and frequencies here affected by many factors, but the majorities were caused by peptic ulcers and esophageal-gastric varices. With development of economy and medical services, new drugs and endoscopic interventions, the treatment of patients with UGI bleeding was more improved. So I would like to evaluate the change of causes and frequencies of UGI bleeding and the associated clinical findings. A total of 1,546 patients presented with UGI bleeding in emergency department of Yeungnam university hospital during the five years from Jan. 1991 to Dec. 1995 were clinically reviewed by charts and compared with previous seven years report from Jan. 1984 to Dec. 1990 in the same hospital. The ratio of male to female was 6.1:1 and slightly increased in comparison with previous seven years. The incidences in 6th and 5th decades were highest(54.4%) as like as previous seven years. Age distribution of duodenal ulcer bleeding, Mallory-Weiss tear and acute gastric mucosal lesion were developed in lower decades than the others. The causes of UGI bleeding were caused by esophageal varix(45.4%), peptic ulcer(38.8%), Mallory-Weiss tear(4.3%), gastric cancer(3.8%), others(3.1%), acute gastric mucosal lesion(2.7%), undetermined causes(1.8%) in defending order of frequencies. The proportion of esophageal varices was increased from 36.6% to 45.4%, but that of peptic ulcer was relatively decreased from 47.6% to 38.8%. And the annual distribution of varices was increased, however the annual distribution of peptic ulcers was increased. Although the ranking of annual distribution of gastric ulcers and duodenal ulcers were not changed compared to previous study and the frequency of gastric ulcers was increased since 1992, but additional follow-up was needed. Seasonal variations were found that upper gastrointestinal bleeding was increased in fall and peptic ulcer bleeding was increased significantly in summer and fall, however, varix bleeding was less frequent in summer time as like as previous seven years. Emergency endoscopic examination was performed within 6 hours far 54.5%, 24 hours for 90.8% and this reacts were to be like previous results, 57.5% and 90.7% respectively. Findings of emergency endoscopic examination were active bleeding focus(21.2%), blood clot(7.9%), exposed vessels(13.3%), flat blood spot(6.4%) and lesion without evidence of bleeding(51.3%). Endoscopic findings of active bleeding were easily seton when examination was perfomed within 24 hours. Blood transfusion was performed in 67.3% with average 2.1 units. When the causes of bleeding were due to varix and marginal ulcer, more amounts of blood were transfused than the others. In previous seven years, blood transfusions were performed in 71.2% with average 5 units and more amounts of blood were transfused in gastric cancer and varix bleeding.
