The clinical features of cutaneous manifestations in 411 patients with Behcet's syndrome were studied. 302 patients (73.5%) had skin lesions. The frequency with which the following skin lesions were noted was, in decreasing order; erythema nodosum-like lesion, papulopustular eruption, erythema multiforme-like lesion, thrombophlebitis, ulcer and Sweet's syndrome-like lesion. More than two types of skin lesions were seen in 86 patients (28.5%), the combination of the skin lesions being in decreasing order, erythema nodosum-like lesion and papulopustular eruption; erythema multiforme-like lesion and papulopustular lesion; erythema nodosum-like lesion and thrombophlebitis. A skin pathergy test was performed on 245 patients, and a positive reaction was seen in 97 patients (39.6%). This study showed the high incidence, wide spectrum and importance of skin lesions as a major symptom in Behcet's syndrome.

We surveyed 26 employees of a shell-handling factory on whom skin tests with 12 common allergens and shell powder extract were done. Specific bronchial Provocation tests with shell powder extract were performed on the subjects who had respiratory symptoms. Positive skin responders to shell powder extract were 8 among the 26 subjects (30.8%), and subjects who were positive responders to any one of 12 common allergens showed a higher positive rate than negative responders. Among the 8 subjects who had a positive skin response, four had respiratory symptoms. Three subjects were positive bronchial responders to bronchial provocation tests.

BACKGROUND: With the development of medical science and technology, the proprotion of the aged has been significantly increasecl. Therefore it needs to be studied the fuadamental epidemiologic survey of dermatologic diseases and akin care in the elderly. OBJECT: Our purpose was to provide clinically relevant data regaring both dermatologic diseases and skin care in the aged population. MEHTODS: Total 172 volunteers aged 51 to 90 were enrolled in a study of 32-item questionnaire and total cutaneous examination. RESULTS: The sex ratio of male to female of 172 elderly volunteers as 1:1.4 and population of 7th and 8th decades occupied 76.5% with their mean age 74.4. The dermatologic findings which showed higher incidence in this study were seborrheic keratosis, senile lentigines, xerosis, cherry angioma, and generalized pruritus. Through the interviews of 172 elderly, the mot fequent dermatologic complaint was generalized pruritus. As the mean age of the population increasec, the number of the population showing xerosis and complaing of pruritus was elevated(r=0.976. 0.917 respectively). And there was a significant stastical correlation between the finding of xerosis and the the presence of pruritus(P<0.005). CONCLUSION: This study suggests that dermatologic problems in the elilerly are very common ancl further dermatologic studies including substantial medical care will be needed.

skin disease (OSD) is a commonly known occupational disease. However, epidemiological data about this condition in Korea are limited. We aimed to estimate the prevalence and risk factors of OSD using nationally representative data.MATERIALS AND METHODS: We used data from the large-scale, cross-sectional, nationwide 4th Korean Working Conditions Survey conducted in 2014. OSD was defined as skin diseases caused or aggravated by working environments as indicated in a self-reported questionnaire. Factors affecting the occurrences of OSD were investigated using logistic regression analysis.RESULTS: The prevalence rates of OSD were 1.35% in all workers and 62.2% in workers with skin diseases. The workers with OSD were older, had lower educational levels, and had longer working times per week than those without OSD (p<0.001). Furthermore, OSDs occurred more frequently in self-employed workers (p=0.002), those with small-sized businesses (p=0.008), those with longer working durations (p<0.001), and manual and service workers (p<0.001). Although the workers with OSD had greater exposure to various hazardous factors, logistic multivariate analysis showed that high temperatures and skin contact with chemical products were significantly correlated (odds ratios: 2.096 and 2.326, respectively). High prevalence rates of OSD were observed in membership organizations/repair/other personal services (3.2%), agriculture/forestry/fishing (2.7%), manufacturing (2.0%), and construction (1.6%) industries. Additionally, depression/anxiety problems were significantly more prevalent in workers with OSD than in those without (p<0.001).CONCLUSION: This is the first study to present large-scale epidemiological data on OSD prevalence in Korean workers. Our results highlight modifiable factors contributing to the development of OSDs.]]>

OBJECTIVETo investigate cutaneous aging patterns of residents in Hangzhou, Zhejiang, China, and their contributing factors.

METHODSEight hundred and forty-eight Hangzhou residents received the survey between March 2004 and September 2004.

RESULTSFacial wrinkling first occurred at 21 years of age and skin elasticity began to lose at 22 years of age. In middle-aged and old people, facial wrinkling and looseness escalated with the increase of ultraviolet (UV)-exposure time, indicating the accelerating effect of a higher accumulative dose of UV radiation on skin aging. Only Fitzpatrick types II, III and IV were found in the skin phototypes of residents in Hangzhou area, and Fitzpatrick type II seemed to be much more subject to severe wrinkling, elasticity destruction and skin tumors than types III and IV. The oily skin was more protected against wrinkling and facial looseness than dry skin. However, as to concomitant cutaneous diseases, no difference was found among different skin types.

CONCLUSIONAge, solar-exposure time, Fitzpatrick type and skin type are the associated forces in promoting skin aging, and emotional factor seems to be another independent risk factor. The age of 49 years and 2 h/d of solar-exposure time seem to be the turning points responsible for dramatic changes of cutaneous appearance in the process of skin aging in Southeast China.

INTRODUCTIONThere is no published epidemiological data on skin diseases in kidney transplant recipients in this tropical country, which has multi-ethnic groups with the Chinese as the predominant ethnic group.

MATERIALS AND METHODSSkin diseases of 143 renal transplant recipients were studied in a skin clinic of a tertiary institution during annual surveillance visits from June 2006 to March 2009.

RESULTSOur study showed that except the common drug specific skin manifestations, sebaceous hyperplasia (56.6%), seborrheic keratosis (60.8%), melanocytic naevi (76.9%), skin tags (37.1%) and viral (29.4%) and fungal (20.3%) infections were the most prevalent skin diseases among renal transplant recipients living in Singapore. The prevalence of pre-malignant and malignant tumours was very low (11.2% actinic keratosis, 1.4% Bowen's disease, 1.4% squamous cell carcinoma, 0.7% basal cell carcinoma, 0.7% keratoacanthoma). Male predominance was seen in sebaceous hyperplasia (72.4% vs 32.1%), actinic keratosis (17.2% vs 1.8%), viral (36.8% vs 19.6%) and fungal (27.6% vs 8.9%) infections. Our study also showed increased prevalence of sebaceous hyperplasia with increased age but its prevalence was significantly higher than that reported in the age matched general population. The prevalence of seborrheic keratosis, actinic keratosis and viral infection correlated positively with post-transplant duration.

CONCLUSIONSOur study provides epidemiological data for the prevalence of skin diseases in renal transplant recipients. It emphasises the importance of dermatologic follow-up for renal transplant patients in order to obtain a diagnosis and manage treatable skin diseases.

BACKGROUND: Genital skin diseases are common, yet there has been insufficient clinical investigation of these conditions. OBJECTIVE: This study was performed to investigate the epidemiological aspects of genital skin diseases, and to highlight the clinical features of common dermatoses of the genitalia. METHOD: We retrospectively reviewed data of 84 patients biopsied for genital skin lesions at Maryknoll Hospital between September 1991 and August 2004. RESULTS: The ratio of males to females was 2: 1 (56: 28). The most frequent genital skin diseases present were lichen simplex chronicus, condyloma accuminata, irritant contact dermatitis, lichen sclerosus et atropicus and calcinosis cutis in decreasing order of frequency. Of the 84 cases, 42 had patches or plaques, 36 had papules or nodules and 16 had vesicles, erosions or ulcers. CONCLUSION: Our results were similar to other studies in some cases and different from others in other cases. Further investigation with a larger group of patients is necessary to better understand the epidemiology of genital skin diseases.
