ABSTRACT
Objective To investigate the prevalence of dermatosis affecting pilots in different areas. Methods From Oct. 2007 to Sep. 2008,epidemiological investigation and clinical examination were carried out in 255 pilots stationed at Beijing,Tianjin,Hubei and Shaanxi regions. In order to get the correct diagnosis of dermatosis and the accurate number of infection cases/time,same medication and management were applied for the treatment of those skin disorders. The epideomology of dermatosis in pilots of different troops and age groups were then compared,and the correlation factors affecting the epidemics were analyzed with Chi-square test. Results Among 255 pilots,430 cases (times) were found to suffer from 47 kinds of dermatosis,of whom 72% suffered from two or more kinds of dermatosis. The incidence of superficial mycosis (69.8%) took ranked the highest. The incidence of dermatosis was different among the pilots stationed in different regions. The prevalence of lichen simplex chronicus was higher in the pilots stationed in Beijing,Tianjin and Shaanxi regions than in those in Hubei region,while the prevalence of tinea manuum and tinea pedis showed the opposite status (P 7 year enlistment (P
ABSTRACT
Objective To investigate the prevalence of dermatoses affecting officers and soldiers garrisoned southeast China,and to provide enough scientific basis for prevention and treatment of those dermatoses.Methods Epidemiological investigations were carried out on 324 officers and soldiers in both Zhejiang and Fujian military Regions,respectively.In order to get the dermatoses diagnosed correctly and the number of infected men/times calculated accurately,a large scale of clinical examination was performed by 3 senior dermatologists from the authors' hospital.Some medication and management were applied in therapy for those skin disorders.The elementary medical personnel in the troops were trained with a short time-training course to raise their vocational level.Results Tinea manuum and tinea pedis,acne,pigmented nevus,tinea corporis and tinea cruris,seborrheic dermatitis,eczema,pityriasis versicolor and lichen simplex chronicus were the eight common dermatoses affecting officers and soldiers garrisoned southeast China.The prevalence of tinea manuum and tinea pedis was highest one in all the 8 common dermatoses.158 out of 324 soldiers(48.8%)suffered from skin disorder.The prevalence of acne,pigmented nevus,tinea corporis and tinea cruris,seborrheic dermatitis,eczema,pityriasis versicolor and lichen simplex chronicus were 45.4%,19.3%,10.8%,12.3%,10.2%,7.4% and 7.1%,respectively.Conclusions Skin disorder is one of the most common diseases affecting officers and soldiers.There are different occurrences in different garrisoned region.The prevelence of tinea manuum and tinea pedis in Fujian military region is higher than that in Zhejiang military region,and the prevelence of tinea corporis and tinea cruris,eczema in Fujian military region is lower than that in Zhejiang military region.No significant difference was found in the prevalence of the eight common dermatoses between the two parts of soldiers originated separately from north or south regions of China.
ABSTRACT
Objective To find out the material base of the induction and aggravation of psoriasis by psycological factors such as stress and depression etc. Methods Radioimmunoassay (RIA) was used to determine the effect of sera from 49 psoriatic patients and 34 healthy controls on the suppression of the lymphocyte transformation of normal mouse lymphocytes. Results The lymphocyte transformation rate of mouse lymphocytes treated with the sera of psoriatic patients was 41.55%, and that of controls was 68.09%. The suppressive effect of sera in patients during the progressive stage and with more extensive lesions were stronger than that in the stable stage and with less lesions (P
