BACKGROUND: Pityriasis versicolor(PV) is a superficial mycosis, theoretically unusual in children. Epidemiologic and clinical data for children with PV under 14 years were collected. OBJECTIVE: The purpose of this study was to evaluate the clinical features of PV in the young. METHOD: We included all cases of PV in patients under 14 years of age observed in our department from 1981 to 1995. All cases were diagnosed on the basis of clinical criteria and were confirmed by microscopic examination. RESULTS: From 1981 to 1995 we encountered 32 cases of PV in children, compared with 637 cases in adults; thus children represented 4.7% of all cases. The ratio of male to female was l. 7:1. Among the age groups, the incidence was the highest in the 10-14 years(43%). The monthly prevalence was the highest in August. Distribution of the lesions were the face(40.9%), neck (25%), chest(13.6%), back(11.3%), extremities(6.8%) and abdomen(2.2%). The incidence of hypopigmented lesions was 70.4% and that of hyperpigmented lesions was 29.6%. CONCLUSION: This study confirms that the face is a predilectionl site for PV in children and all facial lesions are hypopigmented. Other clinical features are variable and similar to those of adults.

OBJECTIVE: To test the hypothesis that a safety margin may affect local tumor recurrence (LTR) in subsegmental chemoembolization. MATERIALS AND METHODS: In 101 patients with 128 hepatocellular carcinoma (HCC) nodules (1-3 cm in size and < or = 3 in number), cone-beam CT-assisted subsegmental lipiodol chemoembolization was performed. Immediately thereafter, a non-contrast thin-section CT image was obtained to evaluate the presence or absence of intra-tumoral lipiodol uptake defect and safety margin. The effect of lipiodol uptake defect and safety margin on LTR was evaluated. Univariate and multivariate analyses were performed to indentify determinant factors of LTR. RESULTS: Of the 128 HCC nodules in 101 patients, 49 (38.3%) nodules in 40 patients showed LTR during follow-up period (median, 34.1 months). Cumulative 1- and 2-year LTR rates of nodules with lipiodol uptake defect (n = 27) and those without defect (n = 101) were 58.1% vs. 10.1% and 72.1% vs. 19.5%, respectively (p < 0.001). Among the 101 nodules without a defect, the 1- and 2-year cumulative LTR rates for nodules with complete safety margin (n = 52) and those with incomplete safety margin (n = 49) were 9.8% vs. 12.8% and 18.9% vs. 19.0% (p = 0.912). In multivariate analyses, ascites (p = 0.035), indistinct tumor margin on cone-beam CT (p = 0.039), heterogeneous lipiodol uptake (p = 0.023), and intra-tumoral lipiodol uptake defect (p < 0.001) were determinant factors of higher LTR. CONCLUSION: In lipiodol chemoembolization, the safety margin in completely lipiodolized nodule without defect will not affect LTR in small nodular HCCs.

BACKGROUND: The testes are one of the most common extramedullary sites of relapse in boys with acute lymphoblastic leukemia(ALL). The reported incidence of isolated testicular relapse varies from 3 to 40%. If these patients are treated exclusively with testicular irradialion, a systemic relapse occurs within a few months. Recently, the use of intensive chemotherapy and testicular irradiation improved the survival rate for boys with testicular leukemia. So, we performed this study to identify clinical manifestations, disease free survival and prognostic factors of testicular leukemia in children. METHODS: We reviewed 33 patients of testicular leukemia among total 410 boys with ALL diagnosed at the Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1970 to Aug. 1996. Testicular leukemia was confirmed by testicular biopsy in all 33 patients. These patients were treated with combined local testicular irradiation(2,400~2,500 cGy/8~12fractions) and systemic chemotherapy. Two patients, in whom testicular relapse was diagnosed before 1979, unilateral orchiectomy of the involved site and testicular irradiation of the opposite site were performed. Probability estimates of disease free survival (DFS) were calculated by the method of Kaplan and Meier, and the relationship of prognostic factors to DFS was compared using the chi-square test in survival analysis. RESULTS: In 410 boys with ALL, testicular leukemia occurred in 33 patients(8%). Of 33 patients, 6 patients presented with testicular involvement at initial diagnosis, 16 patients had testicular relapse while still receiving chemotherapy and 11 patients had testicular relapse 3 to 57 months(median : 15 months) after cessation of chemotherapy. The median age of 33 patients was 7.4 yrs(9 months~18 yrs) and median WBC count 7,600/ L(2,700~270,000/L). All patients presented with painless testicular enlargement and testicular leukemia was confirmed by testicular biopsy. Among 33 patients, 2 had prior CNS relapse and 11 had concomitant bone marrow and/or CNS relapse. Twenty nine patients were treated with combined local testicular irradiation and systemic chemotherapy. Eleven had second relapse(6 bone marrow, 3 CNS, 2 opposite testis). Seventeen have been followed until now: 6 patients on chemotherapy and 11 patients(37.9%) in complete remission for 48.5+/-22.3 months(19~86 months). The 3 year DFS for 29 patients was 55.3%+/-10.1%. The following prognostic factors showed no significant association with DFS in testicular relapse : age and WBC count at initial diagnosis, age at testicular relapse, and concomitant relapse. Whether testicular relapse occurred on initial therapy or off initial therapy has prognostic value in predicting DFS. The 3 year DFS for boys with testicular relapse on and off initial therapy were 40.0%+/-12.9% and 78.8%+/-13.4%, respectively(P: 0.046). CONCLUSION: With the use of chemotherapy and testicular irradiation, prolonged second re mission can be achieved in many patients with testicular leukemia. The patients with testicular relapse off initial therapy fared significantly better than patients on therapy. So, to improve the DFS for boys with testicular leukemia, a better understanding of its biology and prognostic factors is needed.

PURPOSE: Many patients with benign prostatic hyperplasia (BPH) have storage symptoms. The aim of this study was to evaluate the effects of treatment with a 5-alpha reductase inhibitor (5ARI) on storage symptoms in patients with BPH. METHODS: This study was conducted in 738 patients with lower urinary tract symptoms secondary to BPH. Patients with a prostate volume of higher than 30 mL on the transrectal ultrasound were classified into two groups: group A, in which an alpha blocker was solely administered for at least 12 months, and group B, in which a combination treatment regimen of an alpha blocker plus 5ARI was used. This was followed by an analysis of the changes in parameters such as the total International Prostate Symptom Score (IPSS), voiding symptom subscore, and storage symptom subscore between the two groups. In addition, we examined whether there was a significant difference between the two groups in the degree of change in storage symptoms between before and after the pharmacological treatment. RESULTS: Of the 738 men, 331 had a prostate volume > or =30 mL, including 150 patients in group A and 181 patients in group B. Total IPSS, the voiding symptom subscore, and the storage symptom subscore were significantly lower after treatment than before treatment in both groups (P<0.05). A comparison of the degree of change between before and after treatment, however, showed no significant differences in the storage symptom subscore between the two groups (P>0.05). CONCLUSIONS: Alpha blocker and 5ARI combination treatment is effective for patients with BPH including storage symptoms. However, 5ARI does not exert a significant effect on storage symptoms in BPH patients.

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”.

We report a case of Kyrle's iisease occurring in a 60-year-old woman with chronic renal failure. The patient had multiple hyperkeratotic papules with a central plug on the back, and in the upper and lower extremities. Histopathological findings showed epidermal invagination filled with parakeratotic column and basophilic debris. Many dyskeratotic and vacuolated cells were present below the keratotic plug, and penetration of the parakeratotic column into the dermis was seen.

Background:
Onychomycosis, a common fungal nail infection, particularly affects the elderly. The diagnostic accuracy of a potassium hydroxide (KOH) smear, a primary diagnostic method, can vary based on the examiner’s proficiency.
Objective:
To evaluate the diagnostic utility of KOH smears in a real-world setting and the influence of clinical and practical factors on onychomycosis.
Methods:
This study included 381 patients who underwent KOH smear and histopathological staining for nail diseases at Seoul National University Hospital between March 2020 and February 2023. The study evaluated the diagnostic utility of the KOH smear, including its sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio. We investigated the influence of factors such as training duration of examiners, prior history of antifungal treatment, and lesion location on diagnostic utility.
Results:
Of the 381 patients, 139 were male (36.5%) and 242 were female (63.5%). Onychomycosis was the most common diagnosis (59.3%), with 34.1% of patients reporting prior antifungal therapy within the past 6 months. The sensitivity of the monthly KOH smear varied from 16.7% to 70.0% with an annual sensitivity of 48.1%. The specificity ranged from 83.3% to 100.0%, with an annual specificity of 90.3%. While prior antifungal therapy decreased the sensitivity and specificity, no statistical significance was observed. Examiner's experience, measured by training duration, was not associated with sensitivity or specificity. Among patients with a history of antifungal treatment, an increasing number of KOH smear tests showed reduced sensitivity.
Conclusion
Variations in the diagnostic utility of the KOH smear test, influenced by various factors, highlight the necessity for cautious interpretation in clinical settings.

PURPOSE: We have undertaken this study to evaluate the effects of induction chemotherapy involving BH-AC, idarubicin, and 6-thioguanine (6-TG). METHODS: BH-AC 300mg/m2/day was administered intravenously over three hours for seven consecutive days. Idarubicin 12mg/m2/day was administered intravenously for three days. 6-TG 100 mg/m2/day was administered orally for seven days. Intrathecal ara-C was administered on the first day of treatment. RESULTS: Complete remission (CR) was achieved in 18 cases (66.7%), partial remission (PR) was achieved in 2 cases (7.4%). In previously untreated patients, complete reimission rate was 92.9% (13/ 14), in relapsed patients, 40% (2/5) and in the refractory patients, 37.5% (3/8). The remission duration until December 1996 was 45 to 630 days (median 133). Duration of the neutropenia (ANC<500/microliter) was 0 to 38 days (median 24). Side effects were nausea, vomiting (7/27, 25.9%), liver dysfunction (1/27, 3.7%), skin eruption (1/27, 3.7%), and mucositis (1/27, 3.7%). In all cases, fever developed in the neutropenic state (culture proven sepsis in 5 cases). Death occurred in 5 cases who achieved CR due to sepsis after chemotherapy (4 cases), intracerebral hemorrhage after bone marrow relapse (1 case). CONCLUSION: BH-AC, idarubicin, and 6-TG induction chemotherapy could be a useful induction chemotherapy treatment that combines supportive care for infection and bleeding.

PURPOSE: We evaluated the response to immunomodulation therapy, long-term survival and relapse rate of aplastic anemia during follow-up for more than 1 year. METHODS: Twenty-eight children, with moderate to severe aplastic anemia were followed for more than one year and 7 children expired after therapy, were analyzed. Antilymphocyte globulin (ALG) or antithymocyte globulin (ATG) by itself was given to 27 patients, and cyclosporine A (CsA) combined with ALG was given to 8 patients. ALG (ATG) was administered for 8 days in 20mg/kg/day when used alone, and for 5 days in 10mg/kg/day when combined with CsA. CsA was orally administered on the 14th day till 180th day of therapy, with 5mg/kg/day for first 14 days and 3mg/kg/day thereafter. RESULTS: Fifteen out of 35 patients (43%) showed a response. Median interval to response was 3 month (1-40 months). Response rate to ALG + CsA was 50%, compared to 41% in ALG (or ATG) alone. The interval of aplastic anemia symptoms to treatment showed a tendency to be shorter in responders (4.1 +/- 2.2 months) than in non-responders (17.5 +/- 6.4 months). Relapse occurred in 3 of 15 responders (20%). Evolution to secondary clonal hematologic disorders was not observed. Overall actuarial survival at 3 year was 78.2%. CONCLUSION: The results of immunomodulation therapy suggest that response would be better for patients whose interval from symptoms of aplastic anemia to treatment is short. Our results also suggest that ALG+CsA would be a better treatment modality to improve response rate.
