The need for film recording in endoscopic practice is important with the present demand for documentation and teaching (legal problem). The electronic endoscopy which has a very small charge coupled device (CCD) at the distal end of an endoscope yields several times more resolving power than conventional optical endoscopes. However the system has not been utilized in Urologic field because there has not enough space for CCD at the end of the telescope comparing to the endoscope in Gastroenterology field. However the video converter with CCD could be adapted to the eyepiece of the telescope, and the automatic monitor photo unit (CVP 600, SAMSUNG, KOREA), video system and monitor were used for imaging, which is so called Urologic Video Information System (UV1S). The image processing was done by instantaneous system (CCD color camera, EC-202 II, ELMO, Japan) with conventional optical light source. From September 1992 to August 1996, we did cystoscopic examination with CCD in 1079 cases.

BACKGROUND: There are many reports about the correlation between cardiovascular disorders and estrogen deficiency in postmenopausal women. The purpose of current study is to know that postmenopausal estrogen therapy may affect the lipid metabolism and endogenous fibrinolytic system and exercise tolerance. METHOD: We investigated the relation of estrogen treatment (srogen 0.625 mg/day) to serum lipid levels, angiotensin converting enzyme activity, plasminogen activator inhibitor-1 and parameters of treadmill test in 22 postmenopausal women of normal coronary artery with abnormal exercise test complained with chest pain accompanied by postmenopausal symptoms. RESULTS: Estrogen treatment significantly elevated the serum HDL-cholesterol level (42.8 to 50.1 mg/dl, p<0.05) and reduced the PAI-1 level (16.2 to 10.4 ng/dl, p<0.01) without considerable side effects. During the exercise test, the positivity appearance time and total exercise duration is significantly increased after estrogen treatment. CONCLUSION: The postmenopausal use of estrogen favorably changed the lipid level, fibrinolytic system and might improve the microcirculation which may protect against the ischemic heart disease risk without significant side effects.

Aggressive fibromatosis is a neoplastic lesion derived from musculoaponeurotic tissue. By its ability to spread locally and infiltratively, it mimics a low-grade malignant tumor. Wide excision is the recommended primary therapy but recurrences are numerous. We report a primary pelvic fibromatosis arising from retroperitoneum, which managed by surgical excision and radiation therapy.

PURPOSE: Various causes may be the etiology of gynecomastia. We investigated the levels of serum estradiol (E2), testosterone (T), ratio of E2 to T (E2/T) as well as associated diseases, drugs as the cause of gynecomastia. MATERIALS AND METHODS: E2, T, E2/T in 37 patients from gynecomastia patients (GP) and 10 healthy men were measured, and the associated diseases and drugs in 68 GP were also evaluated. Ultrasound for the adrenal gland diseases, physical examination or ultrasound for the testicular pathology were performed. RESULTS: The cause of gynecomastia varied according to the age. The levels of E2, T, E2/T in control group (CG) were 35.3 3.9 pg/ml, 5.0 0.4 ng/ml, 7.1 0.5. Those in GP were 48.7 7.1 pg/ml, 4.3 0.3 ng/ml, 12.0 1.8, respectively. The difference of E2/T as well as E, T between CG and GP was not significant. Various associated diseases or drugs were found in GP. Adrenal diseases or testicular cancer were not found in GP. CONCLUSIONS: The difference of E2/T between CG and GP is not the only cause of gynecomastia. Thus, the consideration of the age as well as associated diseases or drugs will be helpful for the better understanding of high E2/T as the cause of gynecomastia

Interrupted aortic arch may be defined as a discontinuity of the aortic arch. This uncommon anomaly was first described by Steidele in 1778 and was later classified into 3 types by Celoria and Patton. We experienced the case of a 25-year-old male with an interrupted aortic arch(Type B) which was well supplied by collateral circulations. Ligation of collateral supplies and a Y-graft replacement from ascending aorta to descending thoracic aorta and left subclavian artery was done. Postoperative aortogram revealed no collateral circulations and good continuity of the aorta without narrowing of the anatomic site. During the period of 2-month follow up, the patient was able to lead a relatively active life.

Malacoplakia is an uncommon granulomatous inflammatory disease, which predomina- ntly affected the urinary tract, particularly the urinary bladder. The prostatic involve- ment of malacoplakia is extremely rare and may clinically mimic prostate cancer. A correct diagnosis of malacoplakia can be made by histopathologic findings characterized by accumulations of macrophages containing typical intracytoplasmic inclusions(Michael is-Gutmann bodies). We report a case of prostatic malacoplakia, which was incidentally found in prostate biopsy performed to confirm clinically suspected prostate cancer.

Metastatic urethral tumor is extremely rare. We report a case of anterior urethral and hepatic metastasis from a rectal adenocarcinoma developed 17 months after radical resection of rectal cancer. The patient was performed suprapubic cystostomy for management of voiding difficulty, thereafter, died 4 months after presentation.

BACKGROUND: In survivors of acute myocardial infarction(ANI), reduced heart rate variability(HRV) has been demonstrated to be an independent predictor of sudden cardiac death and mortality. The heart rate variability can be examined and analyzed non-invasively and quantitated with 24-hour ambulatory ECG monitoring. In general, the patency of infarct-related artery appears to be one of the most important prognostic factor after AMI. Therefor, the correlation between infarct artery patency and HRV was examined in survivors of AMI. METHODS: The 24-Hour ambulatory electrocardiogram was performed in 23 patients with AMI and 20 normal controls, and analyzed for frequency & time domain HRV. HRV was recorded dwithin 7 days after AMI, and coronary angiogram was performed at 7th day after AMI. The AMI patients were divided into two groups, depending upon patency of infarct-related artery and correlated to clinical manifestations. Thirteen patients had patent vessel(Group 1) and ten patients had non-patent vessel(Group 2). Parameters of frequency domain HRV include LF, HF & LF/HF ratio and time domain HRV include SDNN, SDANN, SD, rMSSD and pNN50. RESULTS: All parameters of HRV was depressed in patients of AMI than in normal control(p<0.05). The mean left ventricular ejection fraction(LVEF) was 54.1+/-10.6% in group 1 and 42.6+/-12.2% in group 2(p<0.05). The mean values of LF, SDNN, SDANN, and SD in group 1 and group 2 were 5.09+/-0.83msec2/Hz & 4.09+/-0.53msec2/Hz, 84.5+/-24.2msec & 59.0+/-11.8msec, 73.2+/-22.8msec & 50.5+/-12.6msec, and 37.8+/-13.1msec & 27.2+/-4.4msec(p<0.05), respectively. There was no difference between two groups in HF,rMSSD and pNN50. The location of infarction and thrombolytic therapy itself did not influence of HRV. The mean values of HF, SDANN, rMSSD and pNN50 in patients with LVEF<40% were reduced significantly than in patients with LVEF> or =40%. There was a significant correlation between LVEF and LF, between LVEF and HF and between LVEF and LF/HF ratio(r:0.55, p<0.05;r:0.67, p<0.05;r:-0.56, p<0.05). CONCLUSION: HRV was depressed due to reduced vagal activity in patients with AMI. The values of LF, SDNN, SDANN, and SD in group of patent infarct-related artery were reduced significantly than in non-patent group.

Primary pulmonary hypertension is a rare and progressive disease with poor prognosis. Despite much previous studies, there is neither clear explanation in the etiology and the pathogenesis nor confirmative treatment modalities. Its main cause of death is due to the right ventricular failure but the left ventricular function is relatively well preserved. The chest pain mimickig the angina pectoris is common and it is mostly due to the right ventricular ischemia or distension of pulmonary artery, but left ventricular ischemia or infarction is very rarely seen. We experienced a case of primary pulmonary hyperetension with left ventricular hypertrophy that complicated to acute myocardial infarction in 14-year-old male.
