Dermato-allergological risks in beauty operators.

Beauticians, hairdressers, and barbers are among the occupations with the highest rates of work-related skin diseases, especially occupational contact dermatitis (OCD). Irritant contact dermatitis (ICD) due to chronic mild trauma (frictional dermatitis), contact with soaps, detergents, and wet work is frequent in beauty operators. Para-phenylenediamine (PPD), acrylates, essential oils, fragrances, colophony, and preservatives are most frequently responsible for allergic contact dermatitis (ACD) in these professional categories. Young women are mainly affected, with the most affected sites being the hands. Anamnesis, patch tests with the baseline, integrative series, and use products are important to understand possible sensitization. To reduce the risk, prevention is important, and workers should be adequately trained in the use of personal protective equipment (PPE).

Acquired ichthyosis and hypertrichosis due to autoimmune thyroiditis: therapeutic response to thyroxine replacement.

Thyroid diseases may be associated with a wide variety of dermatologic disorders. We report a 15-year-old girl with acquired ichthyosis and hypertrichosis associated with hypothyroidism resulting from autoimmune thyroiditis. Her skin lesions progressively resolved after 8 months of replacement therapy with L-thyroxine. This result supports the hypothesis that hypothyroidism in our patient can be directly related to the pathogenesis of acquired ichthyosis and hypertrichosis.
