The outcomes of treatment of 31 patients who were managed by single visual internal urethrotomy were compared with those of 25 patients managed by perineal urethroplasty to asses whether the replacement of almost urethroplasty by the simpler urethrotomy was justified. The overall successful results were achieved in 51.6% of visual internal urethrotomy and 76%, of urethroplasty. Patients with anterior urethral strictures more than 1 cm long or completely obliterated strictures had higher failure rates in the visual internal urethrotomy than urethroplasty (p<0.05). The morbidity rates were 9.6% in the visual internal urethrotomy and 24% in the urethroplasty. We recommend that visual internal urethrotomy be reserved for patients with urethral strictures 1 cm or less in length and posterior urethral stricture which is supposed to have a high recurrence rate since the procedure is simple and it does not compromise asecondary urethroplasty.

In order to investigate the efficacy and safety of oral fosinopril, a new phosphorus containing angiotensin converting enzyme inhibitor, a single dose of 10 to 20mg was administered in 23 hypertensive patients with diastotic blood pressure above 95mmHg and all other anti-hypertensive agents were not administered during 4 weeks of study. Blood pressure and heart rate were measured on the 2nd and 4th week of therapy. The complete blood count with platelet count, blood chemistry by SMA-12 and serum electrolytes were performed at the begining and 4th week of therapy. The urinalysis and electrocardiography were performed at the beginning and 4th week of therapy. Any kinds of side effects were actively questioned by the examining physicians. The following results were obtained : 1) At the beginning and 4th weeks of therapy, the average systolic and diastolic pressure were 170.0+/-17.6/101.6+/-6.1mmHg, 142.7+/-15.1/87.3+/-6.7mmHg respectively. The systolic and diastolic blood pressure were declined statistically significantly(p<0.05) throughout the period of treatment and diastolic blood pressure of all subjects except 3 patients(86%) was maintained below 90mmHg after 4th week of treatment. 2) There was no significant change in the pulse rate before and after therapy. 3) There were no significant changes in blood chemistry, serum electrolytes, hematologic findings, urinalysis and electrocardiographic findigns. 4) side effect were developed in 5 patients(23%) with dry cough, 3 patients(13%) with headache and 2 patients with facial edema but side effects were mostly mild in nature without potenitally serious episodes. These results suggested that antihypertensive therapy with onec-daily fosinopril was effective and well tolerated in essential hypertensive patients.

Purpose:
To report a case of arteritic anterior ischemic optic neuropathy diagnosed with brain magnetic resonance imaging (MRI) for temporal arteritis instead of temporal artery biopsy.Case summary: An eighty-three years old female visited our clinic for right blurred vision for 2 weeks ago with occipital headache for 4 months and mastication problems. Initial best corrected visual acuity was 0.1 in right eye. She had right inferior altitudinal visual field defect and superior pale optic disc swelling with few cotton wool spots were checked. In serologic tests, erythrocyte sedimentation rate, C reactive peptide, and rheumatoid factor were increased, and fluorescent antinuclear antibody was positive. We performed high resolution brain MRI which could find superficial temporal artery’s luminal signal. In MRI image, we could find loss of intraluminal signal intensity void with total luminal obstruction. We assumed as arteritic anterior ischemic optic neuropathy and high dose intravenous steroid was done. Visual acuity of right eye was 0.9 and central scotoma was improved 1 week after intravenous steroid. We changed to oral steroid with tapering and added oral azathioprine. After 11 months of oral steroid use, her visual acuity was 0.9 in right eye and inferior altitudinal visual field defect was much improved.
Conclusions
A patient suspected anterior ischemic optic neuropathy was diagnosed by brain MRI with abnormalities in superficial temporal artery. Visual acuity and visual field defect were improved by steroid and immunosuppressive treatment for arteritic anterior ischemic optic neuropathy.

Objectives:
. To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system.
Methods:
. In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the “optimal surgical site” were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line. In three patients, we implanted the Baha Attract according to the newly developed surgical procedure and validated the feasibility of this technique with a navigation system.
Results:
. We identified the appropriate position of the implant on the temporal bone, suggesting a simplified surgical technique for Baha Attract with a small incision. We determined the spot of implantation, and the implants were inserted through a small surgical incision (<2.5 cm) under local anesthesia; the procedure lasted approximately 30 minutes.
Conclusion
. The optimal surgical site of the temporal bone is a safe and easily accessible location for implantation of the Baha Attract.

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepared for surgery with alpha and beta blocking agents. Two months later, we removed the tumor successfully. A histological study proved that the resected tumor was mediastinal pheochromocytoma. Functional mediastinal pheochromocytomas are rare. Therefore, we reported the case with a literature review.

Endometriosis is defined as the presence of endometrial tissue (gland and stroma) outside the uterus. The most frequent sites of implantation are the pelvic viscera and the peritoneum. About 1% of woman with endometriosis have urinary tract lesions, of which 85% involve the bladder. We report one case of vesical endometriosis that have been treated by partial cystectomy.

PURPOSE: Medicolegal problems start when the patient asserts the mistake of doctor and doctor does not accept it. The purpose of this study is to assess the actual condition of medicolegal problems and to provide solutions of medicolegal problems in the pediatric field. METHODS: There is not official statistical data about medicolegal problems in our country. We gathered data of legal insurance program of Korean Medical Association (KMA) and court cases and other fragmentary data. RESULTS: Between 1981 and 1995, of total 2, 338 cases reported to legal problem insurance program of KMA, most common ones were 748 cases of obstetrics and gynecology. Pediatric case was ranked at the 5th, 74 cases (3.1%). According to analysis of 41 medicolegal cases' after 1990, maltreatment of patient had the highest incidence of 14 cases, injection and medication were related to 12 cases, misdiagnosis was 9 cases, patient management were related to 4 cases, and others were 2 cases. The trial result of the medicolegal cases was that 31 cases were compensated, and 8 cases were defeated, and 2 cases were still in the process. CONCLUSION: The aspect of medical legal problem has the tendency of radicalism and systematization. This brings an economic destitution in the patient and gives damage to a doctor. In order to reduce medicolegal problem, doctor should offer a duty of explanation and efforts to his best to satisfy patient and endeavor to make an intimate doctor-patient relationship.

Male pseudohermaphroditism can be caused by absent m llerian regression, inadequate synthesis of testosterone, inadequate synthesis of dihydrotestosterone, or androgen receptor deficiency. Defects in either the production or the action of androgenic steroids have been demonstrated to cause pseudovaginal perineoscrotal hypospadias, a syndrome of male pseudohermaphroditism. This is mostly caused by a deficiency of 5alpha-reductase, which controls the conversion of testosterone to 5alpha-dihydrotestosterone. We report a case of male pseudohermaphroditism due to 5alpha-reductase deficiency who was born with ambiguous genitalia and was reared as female.
