Abstract
Occupational dermatoses are common enough and sufficiently disabling to demand a wide knowledge from the dermatologists of noxious agents in various occupations. Workers at textile industry are liable to be exposed to different types of noxious agents such as cotton dust with different concentrations, cutting machine oil, cleansing agents and chemical dyes.
The present work aims to study the prevalence of contact dermatitis and bronchial asthma in different sections of this industry.
Therefore, a sample of 310 workers at Dakahlia Spinning and Weaving Factory were choosen for this work. This sample comprised 180 workers exposed to cotton dust, 40 workers exposed to cutting machine oils and cleansing agents, 50 workers exposed to textile chemical dyes and 40 control subjects. Diagnosis was done by good history and clinical examination hence dermatitis which primarily originate from occupational exposure is influenced by many factors. Constitutional factors represent important ones as most manufacturing processes cause dermatitis in certain workers only. If others similarily exposed remain althy, those whose skin breaks clown must have an abnormally low resistance. Such a lowered resistance is found in atopic subjects. The nature of the immune status of the affected our workers were measured by estimation of IgG, IgM and IgE. The other target of this work is to test the validity of patch testing as a priliminary test before working in the same environments by using the substances used in his work. Skin biopsy from the lesion was also taken to confirm the diagnosis of contact dermatitis in our affected workers. Blood count especially for eosinophilia was done to find out the effect of allergenic nature of the substances exposed, urine and stool analysis was carried out to detect any association between contact dermatitis and bilharzial infestation, x-ray chest for all studied groups to exclude other obstructive lung diseases and confirm the diagnosis of asthma which also detect its presence by pulmonary function tests for all studied groups.
