OBJECTIVES: This study was conducted to estimate the incidence of abnormal liver function and risk factors in male employees of an industry in Ulsan City. METHODS: Five hundreds and seventy nine male employees were selected as the study cohort and 533(92.1%) of them were followed after one year. The blood sample was collected to test for AST, ALT, gamma-GTP, total-cholesterol, fasting blood sugar and a self-administered questionnaire on life style was done. General characteristics(age, marital status, educational level), job department, exposure status for organic solvents, life style(alcohol, smoking, exercise, diet), past history of liver disease, family history of liver disease, drug intake, HBsAg, blood glucose, total-cholesterol were considered as risk factors. The result of liver function test after 1 year follow-up was treated as dependent variable. The operational definition of abnormal liver function was as follows; those who had abnormal liver functions in the two repeated tests with one month interval. RESULTS: The annual incidence of abnormal liver function was 9.6 per 100 and age-standardized incidence was 9.5. BMI, alcohol, past history of liver disease, and meat intake were significantly related to the incidence(p<0.05). In multiple logistic regression analysis, BMI(RR=2.70, 95% CI=1.41-5.16) and alcohol(RR=1.98, 95% CI=1.08-3.60) were proved as the significant variables. By stratified analysis considering changing pattern of alcohol and BMI, the relative risk of the BMI normal-normal and alcohol intake high-high group was 2.24(95% CI=1.09-4.62) and that of the BMI obese-obese and alcohol intake high-high group was 5.66(95% CI=2.69-11.88) compared with that of BMI normal-normal and alcohol intake low-low group. CONCLUSIONS: The age-standardized annual incidence of abnormal liver function was 9.5 per 100 in male employees. Thus, an active effort for reducing alcohol intake and controlling BMI should be done to reduce the incidence.

BACKGROUND: In an effort to improve the diagnostic accuracy of the exercise electrocardiography (ECG) to detect coronary artery disease, exercise-induced changes in Q, R and S wave amplitudes has been evaluated in conjunction with or without ST segment changes. We measured the exercise-induced changes in Q, R and S wave amplitudes, and calculated the Athens QRS score to assess its diagnostic value. MATERIALS AND METHOD: Fifty patients who underwent the exercise test and MIBI myocardial scan and were proved to have coronary artery diameter stenosis > or =50% in coronary angiography were included in the patient group. Data of forty-nine persons showing negative findings in the exercise test and MIBI scan were used as control. The exercise test was performed according to the modified Bruce protocol using Marquette case 16. Exercise ECG was positive in 58% (29/50) of the patient group. The Q, R and S wave amplitudes at peak exercise were subtracted from the values of standing position at rest to obtain Athens QRS score. RESULTS: The mean age of patients and control were 54.5+/-9.4 years and 49.8+/-11.4 years respectively (p=NS), and their exercise capacity was 8.5+/-3.1 mets and 9.8+/-1.9 mets respectively (p=NS). The values of delta(R-Q-S)V5 + delta(R-Q-S)aVF and delta(R-Q-S)aVF were significantly lower in patients than the control (0.85+/-6.60 mm vs 3.72+/-5.09 mm, p=0.017, -0.60+/-4.76 mm vs 1.00+/-2.72 mm, p=0.030), and the values of deltaQV5 and deltaSaVF were significantly higher in patients than the control (-0.045+/-0.65 mm vs -0.41+/-0.78 mm, p=0.012, -0.84+/-1.90 mm vs -1.62+/-1.60 mm, p=0.009). However, the values were too widely overlaped between the patients and the control to give diagnostic cutoff points. CONCLUSION: It seems that exercise QRS scores do not have additive diagnostic value for coronary artery disease.

PURPOSE: Visual internal urethrotomy is a standard therapy for incomplete urethral stricture, and may also be a reasonable initial treatment for a short complete urethral stricture. The success rate and final results of the repeated internal urethrotomy were retrospectively assessed to figure out the appropriate indication for visual internal urethrotomy as an initial treatment for incomplete pendulous and bulbous urethral stricture; according to the stricture free month. MATERIALS AND METHODS: Between January 1990 and December 1999, an internal urethrotomy was primarily performed on 166 patients with urethral strictures. The exclusion criteria were complete urethral and posterior urethral stricture. Retrograde urethrography was performed under fluoroscopic control. When the stricture recurred, the urethrotomy was repeated as the primary procedure. RESULTS: With regard to the time to recurrence, the success rate of the group of stricture recurrence at 6 months was significantly lower than that of the stricture free group at 6 months. CONCLUSIONS: With regard to the stricture site and length, the stricture free month might be considered as an important predictor of the outcome of a repeated internal urethrotomy, and visual internal urethrotomy might be considered as an initial treatment method for incomplete urethral stricture under the following conditions; a bulbous stricture, a stricture length under 20mm, and stricture free at 6 months.

Chronic mucocutaneous candidiasis (CMCC) is a general term used to denote a complex group of disorders characterized by a recurrent and persistent infection of the skin, mucous membranes and nails with organism of the genus candida, most frequently Candida albicans. It is often associated with an endocrinopathy and cell mediated immunopathy. CMCC is not a single disease entity, but rather a final common pathway for multiple predisposing abnormalities of the immune system that ranges from severe, life-threatening immunodeficiency syndromes to subtle deficiencies, especially of cell mediated immunity. Conditions that have been associated with CMCC include; candida esophagitis or laryngitis, endocrinopathies (usually hypoparathyroidism, hypadrenalism, hypothyroidism), circulating autoimmune antibodies, diabetes mellitus, vitiligo with antibodies to melanocytes, iron deficiency, chronic active hepatitis, pernicious anemia, malabsorption, alopecia totalis, dental enamel dysplasia, keratoconjunctivitis, pulmonary fibrosis, KED syndrome (keratitis, ichthyosis, and deafness), and recurrent pyogenic, viral or other fungal infections. When CMCC first appaears in adulthood, it is often associated with a thymoma. There is virtually no propensity for disseminated, visceral candidiasis. A suitable clinical classification of the major subtypes of CMCC was described by Lehner and Wells et al into six groups. Kirkpatrick et al found the mean age of onset of CMCC to be 3 years and both boys and girls are affected equally. We review CMCC and 5 reported CMCC cases in the dermatologic literatures in Korea.

Regular hemodialysis has been established as a way of treatment for end stage renal failure. In adults, hemodialysis 5 hours each time, three times weekly with one square meter hemodialyzer is now widely accepted as a standard, and there are many reports on long term follow up studies. Quite a large difference are present, however, in our community mainly originated from patient's poor compliance in frequent dialysis with short interdialysis interval. The author analyzed 200 cases of chronic renal failure who have received hemodialysis treatments during the 5 year period from July 1976 to June 1981 at the hemodialysis unit of the hanyang University Hospital and the following results are obtained; 1. Actual one year survival rate was much higher in thrice(87.1%) than one(35.1%) or twice(54.1%) weekly dialysis. 2. Long term(more than 6 months) complications were also more frequent in once(85.7%) or twice(70.2%) weekly treatments than in thrice(22.2%). The predominant complications were congestive heart failure, pericarditis, and infections. 3. Those who recieved three times weekly dialysis had better rehabilitation grades than the patients groups of twice or once weekly treatment. 4. Of peridialysis distressful symptoms, nausea, vomiting dizziness were less frequent in the group three times a week dialysis. In contrast, headache, hypotension, muscle cramps, and weakness were not significantly related with frequency of hemodialysis. 5. Those who voided a large amount of urine output had better survival and less frequent requirement of blood transfusions. 6. Main causes of death were due to patient poor compliance, hyperkalemia and cerebrovascular acidents. 7. Economic problems were the major cause of dialysis interruption.

Nethertons syndrome is characterized by a triad of ichthyosiform dermatosis, multiple hair-shaft defects(including trichorrhexis invaginata), and an atopic diathesis. Intermittent amminoaciduria, mental retardation, or recurrent infection have been observed in some cases. We have seen an 8-year-old girl presenting with polycyclic, erythematous patches bordered by distintive double-edged scales as a skin manifestation and ball-and-socket deformity as a hair defect.
