Hand eczema among hard-metal workers

Area of Science:

• Occupational dermatology
• Industrial hygiene

Background:

• Hand eczema and irritant contact dermatitis are common occupational skin diseases.
• Hard metal industries involve exposure to various substances and processes that may pose risks to skin health.

Purpose of the Study:

• To investigate the prevalence and incidence of hand eczema and irritant reactions among hard metal workers.
• To identify risk factors and specific work activities associated with these skin conditions.

Main Methods:

• Cross-sectional study of 776 current workers and retrospective analysis of 1,006 former workers.
• Data collection on skin conditions, work history, and atopic background.
• Patch testing for allergic sensitization.

Main Results:

• Prevalence of hand eczema was 10% and irritant reactions 15% in current workers.
• Cumulative incidence of hand eczema over ten years was 17%.
• Early onset (first year) and grinding activities (especially wet and oil grinding) were significant risk factors. Atopy increased hand eczema risk. Patch test positivity was 18% in hand eczema cases.

Conclusions:

• Occupational skin diseases, particularly hand eczema, are prevalent in the hard metal industry.
• Early intervention and specific preventive measures targeting grinding activities are crucial.
• Atopic predisposition is a significant factor in the development of occupational hand eczema.
