A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.

In this study, we have conducted characterization of imaging performance for a flat panel digital X-ray detector using amorphous Selenium and a-Si TFT which was developed by the authors. The procedures for characterization were in concordance with internationally recommended standards such as IEC (international electrotechnical commission). The measures used for imaging performance characterization include response characteristic, modulation transfer function (MTF), detective quantum efficiency (DQE), noise power spectrum (NPS), and quantum limited performance. The measured DQEs at lowest and highest spatial frequencies were 40% and 25% respectively, which was superior to that of commercial products by overseas vendor. The MTF values were significantly superior to that of CR and indirect type DRs. The quantum limited performance showed the detector was limited by quantum noise at the entrance exposure level below 0.023 mR, which is sufficiently low for general X-ray examination.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most commonly reported nerve entrapment syndrome. When performing routine nerve conduction studies (NCS) in clinically diagnosed CTS, we sometimes confronted with patients who have no definite electrophysiological evidence of CTS. Current perception threshold (CPT) test can evaluate the functioning of all major subpopulations of sensory nerve. The purpose of this study is to determine clinically usefulness of the CPT test in idiopathic CTS. METHODS: We prospectively studied 60 patients (90 hands) who were clinically diagnosed as CTS. Involved hands were grouped into three clinical grades (mild, moderate and severe). NCS was done using a standard technique and equipment. CPT test was measured at the distal interphalangeal joint of second, third and fifth fingers with electrical current of 5 Hz, 250 Hz and 2,000 Hz in frequency. RESULTS: Of 60 patients (90 hands), 8 (13.1%) were men and 52 (86.9%) were women. Mean age at evaluation was 56.00+/-8.94 years old. Positive rate of NCS and CPT was 0.80 (0.72, 0.88) and 0.61 (0.51, 0.71), respectively. Sensitive and specificity of CPT test was 0.49 and 0.57. As the clinical severity of CTS deteriorate, CPT test showed abnormality in low frequency stimulation. CONCLUSIONS: CPT test is an effective and relatively simple procedure for measuring perception in CTS. But CTS test is difficulty and subjectively at interpretation. We suggested that the usefullness of CPT test is lower than NCS in diagnosis of CTS.

This study was conducted to compare the date on knowledge, attitude and motivation toward blood donation between donors and non-donors. The study population included 622 donors and 322 non-donors who visited the mobile blood donation car of Taegu Red Cross Blood Center and participated the group appointed blood donation campaign managed by the center from March 1 to March 31, 1989. The donors and non-donors were questioned above mentioned items with a formulated questionnaire. Among the general characteristics of the subjects in the study, male predominance (84.1% in donors and 73.6% in non-donors) in young age group (16-24 years) was the outstanding feature. As a medium of information about blood donation, “television” was playing a dominant role (donors; 75.2%, non-donors; 78.9%), while “magazine” played more important roles among donors. Of the donors, 70.6% and of the non-donors, 58.1 replied that they had ever been induced to donate blood (p<0.01). Major inducers were friend and personnel of mobile blood donation vehicle. On the measuring of knowledge level, the average rates of correct answer was higher in donors (62.6%) than in non-donors (54.1%) (p<0.01). Higher the education level was presented, higher the knowledge level (p<0.05). There have been noticeable difference between donors and non-donors in blood replying the questionnaire set to measure their attitude toward blood donation, especially in the items such as “impression toward blood”, “selection of transfusion blood source” and “view on the situation of blood shortage.” The major motivation toward blood donation of the groups were “possible future need” and “altruism or humanitarian interest”. The major reasons for not donation blood in both groups were “fear of the needle” and “dread to visit to mobile car or center”.

PURPOSE: Crohn's disease (CD) is a chronic inflammatory disease that is difficult to treat due to various complications and frequent recurrences. There have been many studies on the clinical aspects of CD in Western countries; however, there have been few studies in Korea. We performed this study to evaluate the clinical features of CD in Korea and to assess the stability over the course of the disease according to the Vienna classification. METHODS: We reviewed the medical records of 85 patients diagnosed as having CD in Kyung Hee University Hospital from March 1986 to July 2004. RESULTS: The male-to-female ratio was 1.9:1, and the mean age at diagnosis was 27.5 years. The most common symptom was abdominal pain (82%). Perianal lesions were observed in 29 cases (34%). Fistula was the most common (26%) lesion. Extraintestinal manifestations were observed in 13 cases (15%). Stomatitis was the most common (7%) lesion. According to the Vienna classification, the group with ages at diagnosis below 40 years (A1) was 88%, and that with ages equal to or above 40 years (A2) was 12%. The location of the disease was classified as terminal ileum (L1)(15%), colon (L2)(32%), ileocolon (L3)(33%), and upper gastrointestinal (L4)(20%). The behavior of disease was classified as nonstricturing nonpenetrating (B1)(41%), stricturing (B2)(14%), and penetrating (B3)(45%). Empirical anti-tuberculous medications were administered in 23 cases (27%) before the CD had been diagnosed. CONCLUSIONS: There are differences in the locations and behaviors of Crohn's disease between Korea and Western patients. The cause of the difference is uncertain.
