Occupational Contact Dermatitis

Allergic contact dermatitis is common in certain occupations. Irritant dermatitis is seen in 20% of people who work in the following professions:

1. Hairdressers
2. Dentists
3. Florists
4. Construction workers

Hairdressers develop irritant dermatitis quite commonly and also react to PPD dyes. They also react to substances such as glycerol, monothioglycerol, and nickel, which are found in perms.

Dentists can become allergic to the acrylic cements as well as anesthetics. Glutaraldehyde, used in cold sterilization, can also be a problem.

Florists develop both allergic and irritant contact dermatitis. Patch testing is usually required although the most common reaction is to sesquiterpene lactone.
