BACKGROUND: The incidence and causative dermatophytes of tinea cruris has been changed with time. Although clinical and mycologic studies of whole dermatophytosis have been reported many times, there have been only a few studies about tinea cruris reported. OBJECTIVE: The purpose of this study was to investigate clinical and mycological features of tinea cruuis. METHODS: We evaluated the clinical and mycologic aspects of tinea cruris in 598 patients with tinea cruris from January 1985 to December 1997 in Yeungnam University Hospital. RESULTS: The incidence of tinea cruris was 20.8% of 2,878 total dermatophytoses. The ratio of male to female patients was 23.9:1. And most of them were in their twenties and thirties. Most(82.1%) of them involved both sites of the groin. Concurrent dermatophytic infections of tinea cruris were noted in 29.4% of the cases and the most common one was tinea pedis(22.4%). Three hundred and thirty eight dermatophytes were isolated from 598 patients with tinea cruris. They were Trichophyton(T.) rubrum(95.3%), T. mentagrophytes(4.4%), Epidermophyton floccosum(1.2%), Microsporum canis(0.9%). CONCLUSION: Tinea cruris is a male predominant dermatophytosis, the most common causative organism is T. rubrum, and tinea pedis seems to be an important reservoir.

A Listeria monocytogenes infection is relatively rare in healthy adults. However, the chance of an infection increases almost 17 times in pregnancy due to changes in the immune function. A Listeria monocytogenes infection results in characteristic gross and microscopic features in the placenta, including multiple yellowish nodules showing microscopic intervillous abscess and intervillositis. We describe the placental findings of a Listeria monocytogenes infection that was complicated by maternal sepsis, myocarditis and congestive heart failure. The infection was discovered in the 34th week of a twin gestation in a 28 year-old woman. This case should emphasize the importance of this condition to pathologists. Antibiotic treatment was started based on the placental histologic findings before a maternal blood culture confirmed growth of Listeria monocytogenes. Both the mother and twin babies were healthy at the time of this report.

KOH examination is a simple, rapid and diagnostic procedure to confirm dermatophytic infections. It is important to select a proper examination site of the lesion. To determinate the proper examination site of the lesion, mycologic studies were done with multiple specimens collected from the center, margin and out of margin of the ring-shaped dermatophytic skin lesion on the 58 patients. The results were as follows. Positive rate of KOH wet smear was 94.8% at the center and 100% at the margin of the lesions, 22.4% at the 1 cm and 5.2% at the 2 cm out of the lesions. The more hyphae were found in the lesion, the more hyphae were found out of the lesion. Culture was done on the Sabouraud's glucose agar from the highest KOH positive area and the positive culture was 48 strains (82.8%) of 58 patients. These findings suggested that the ring-shaped active margin was the best site to examine mycologic studies.

BACKGROUND: PUVA has been used effectively in the treatment of vitiligo, but the mechanism by which PUVA stimulates melanocyte proliferation in vitiligo is not known. Several mechanisms have been suggested to be involved in the process of repigmentation of vitiligo. First, UV light, with or without psoralen, directly stimulates the proliferation of melanocytes. Secondly, PUVA may act. on epidermal keratinocytes or dermal components to stimulate t,hem to release certain melanocyte growth st,inulation factors that enhance the proliferation of melanocytes in depigmented lesions. Thirdly, PUVA irnmunologically leads to the impairment of epidermal Langerhans cell function and alteration of circulating T and B cell function, which results in the suppression of the stimuli is for rnelanocyte destruction during the therapy. OBJECTIVE: To test, th hypothesis that PUVA induced repigmentation in vitiligo results from the stimulation of growth factors that induce melanocyte proliferation, and that PUVA may suppress the immune reacticin to melanocytes, especially in autoantibody synt,hesis, we examined the effects of sera on the growth of epidermal melanocytes and control cells, and the incidence of antibodies to melanocyte and melanoma cells(SK-Mel 2~3) in the sera of patients with vitiligo. We also had normal control individuals and studied the changes of the antibody titer in the sera of patients with vitiligo. METHODS: The rate of H thymidine uptake was estimat,ed in cultured melanocytes and fibroblasts t,reated by patients sera before and after PUVA treatment. SDS-PAGE and immunoblotting analysis were used to idcntify anti pigment cell autoantibodies and were compared to the titers of autoantibodies after PUVA. RESULTS: 1. Melanocyte and fibrablast proliferation was increased by PUVA treated sera. Their proliferation was in proportion to the duration of the PUVA treatment. Melanocytes proliferated more than fibroblasts. 2. Significant differences between vitiligo patients and normal controls were found in the inci dence of anti-pigment cell antibodies. The antibodies were predominantly directed to melanocyte antigens of 110 kD, 65 kD, 45 kD and melanoma cell antigens of 110 kD, 103 kD, 88kD, 70 kD, 56 kD, 41 kD. 3. The titer of anti piment cell antibodies showed a tendency to decrease after PUVA treat- ment in most patients regardless of clinical improvement. Conclusion ; PUVA treated sera induced proliferation of melanocytes and fibroblasts and the production of aut,oantibodies was suppressed against pigment cell antigens through irnmunosuppression, which might help in the repigmentation of vitiligo.

OBJECTIVES: A different sequence change, in the mitochondrial tRNA gene, has been proposed as a candidate mutation in the sensorineurnal hearing loss. The purpose of current study is to identify the association between the noise-induced sensorineurnal hearing loss and the A to G mutation at nucleotide 3243 of mitochondrial DNA. METHODS: Subjects were established by history and chart review, and audiological and clinical data were obtained. Blood was sampled from 101 controls, 50 noise-induced hearing loss, and 12 sensorineural deafness. The DNA of these individuals was extracted, and mitochondrial genome was analyzed by polymerase chain reaction. Subsequently, the coding sequence of mitochondrial genome was sequenced, and compared to the normal sequence, and all sequence variations were analyzed by restriction endonuclease ApaI. RESULTS: Mitochondrial DNA mutation (3243A->G) was not detected by polymerase chain reaction (PCR) in any patients with noise-induced hearing loss, sensorineural hearing loss, and normal control without hearing loss in Koreans. The DNA sequencing of PCR products did not revealed an A to G substitution at nucleotide 3243 of mitochondrial DNA. CONCLUSIONS: The noise-induced sensorineural hearing loss was not associated with mitochondrial DNA mutation (3243A->G)

This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

BACKGROUND: The elderly is known to have many different clinical laboratory data compared with the young adults. But, in Korea, such study is lacking. METHODS: We gathered 98 healthy elderly cases and 98 healthy young adult controls who have taken periodic health examination from January 1993 to May 1996 at one hospital and we compared the mean of various clinical laboratory data between the two groups. RESULTS: In both sexes, cholesterol, ESR, glucose were significantly higher in the elderly t,han in the controls and direct bilirubin was significantly lower in the elderly than in the controls(P<0.05). In men, albumin, calcium, hemoglobin were significantly lower in the elderly than in the controls and MCV was significantly higher in the elderly than in the controls(P<0.05). In women, alkaline phosphatase, LDH, triglyceride, GOT, GPT, T3,TSH, phosphate were significantly higher in the elderly than in the controls and total bilirubin, protein, uric acid were significantly lower in the elderly than in the controls(P<0.05). WBC count, platelet count, neutrophil count(%), lymphocyte count(%), eosinophil count (%), monocyte count(%), MCH, MCHC, BUN, creatinine, HDL were not significantly different between two groups. CONCLUSIONS: Many clinical laboratory data are different between the elderly and the young adults, and some clinical laboratory data have sexual differences.
