The authors report a study of allergic contact dermatitis in 329 Portuguese children of 14 years or younger. 170 children (64 male and 106 female) reacted to 1 or more allergens. Most of these were in the 11-14 years group. The main allergens were nickel, thimerosal, cobalt, mercury, fragrance-mix and potassium dichromate. Nickel reactivity predominated in females over the whole group, but a greater number of males younger than 5 years reacted to nickel. The number of positive reactions increased with age, but this was not accompained by an increase in the % of relevant tests. 12 children, all of them 13 or 14 years-old, had an occupational allergic contact dermatitis.

6 female patients with allergic contact dermatitis from textile dyes are described. Lesions were confined to areas in direct contact with the offending garment, mainly where friction and/or pressure occurred. Patch tests were positive to 2 or more disperse dyes. Thin-layer chromatography was carried out on the dyes extracted from fabrics of 3 patients, for the identification of textile dyes.
