Tinea pedis is frequently found in people with poor personal hygiene and in hot, humid environments. The authors investigated the clinical, epidemiological, and mycological characteristics of tinea pedis in 170 garbage workers(166 males and 4 females) employed in a garbage plant in Seoul, Korea. 40 were clerical workers and 130 were field workers. Tinea pedis was found in 134 with a prevalence rate of 78.8%. Of those 134, 61(45.5%) also had onychomycosis. The prevalence of tinea pedis increased with age and the period working in garbage plant. However, there was no difference in the prevalence of tinea pedis between clerical workers and field workers, mitigating against the conclusion that their tinea pedis may be of occupational origin. Clinically tinea pedis was classified into 4 types ; interdigital (41.8%), vesicular(23.1%), dry squamous(22.4%), and mixed(12.7%). KOH smear positivity and culture positivity was related to clinical types of the lesion the lowest in the interdigital type. In the interdigital type, the etiology of nonmycotic lesions could not be identified. Negative fungal cultures could have been due to secondary bacterial infections. 63 strains of dermatophytes were isolated; 54 strains of Trichophyton rubrem(85.7%), 8 strains of Trichophyton mentagrophytes(12.7%) and 1 mixed infection of T. rubrum and T. mentagrophytes. T. mentagrophytes was isolated only from the vesicular lesions. 8 strains of yeast forms, positive in KOH smears and yielding pure colonies, were also isolated, and repeated mycologic examination yielded the same results. Among them, at least 4 cases of Trichosporon beigelii, and 1 case of Candida parapsilosis were considered to be of pathogenic significance.

This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.

Cutaneous leiomyoma is a benign tnmor originating from smooth muscle fibers which are derived from arrector pili muscle, media of blood vessels and dartoic muscle of scrotum, vulvar, or nipple. It is classified into 3 types according to the site of origin, namely pilar leiomyoma, angioleiomyoma and genital leiomyoma. Leiomyoma of the nipple is the less kquent type of cutaneous leiomyoma. We report a case of cutaneous leiomyoma on the nipple in a 53-year-old man.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.
