Tinuvin® P in a spandex tape as a cause of clothing dermatitis

We report a 54‐year‐old female with allergic Contact dermatitis from 2‐(2‐hydroxy‐5‐methytphenyl) benzotriazole (Tinuvin® P) in a spandex tape sewn into underwear. Tinuvin® P is used us an ultraviolet light absorber for stabilizing plastics and the other organic materials against discoloration and deterioration. It is effective in protecting synthetic and natural fibers, polyesters, chlorinated polyesters, polyvinyls, cellulose acetate, ethyl cellulose, acrylates, dyes, waxes, detergents, cosmetic formulations, etc. Our patient developed itchy erythema on her shoulders, chest and upper back after wearing underwear for I night. She showed positive reactions to spandex tape sewn into the underwear. She also reacted to 2‐(2‐hydroxy‐5‐meihylphenyl)benzotriazole (Tinuvin P), which was contained in the spandex. No cross‐reaction to other benzotriazoles was seen.

Allergic contact dermatitis due to budesonide

Introduced primarily for babies, moist toilet paper is now also used by adults, both to improve hygiene and to control pruritus ani. The main ingredients are water, fragrances, humectants such as sorbitol, glycerin and propylene glycol, preservatives and surfactants. The allergens are the preservatives and the fragrances (I, 2). Most cased are caused by Kathon CG (3). We analyzed 13 types of moist toilet paper (8 brands), and found that all but 3 contained Kathon CG, at from 5.923.4 ppm in the water phase. Patient no. 4 had allergic contact dermatitis from methyldibromoglutaronitrile, one of the active ingredients of the preservative Euxyl K 400. This preservative is a Kathon CG substitute: patient no. 3 had used the same paper brand, which at that time (1988) still contained Kathon CG. Few cases of contact allergy to Euxyl K 400 have yet been reported (4). This case will be expanded on elsewhere (5). We suspect that contact allergy to moist toilet paper is not uncommon, even though few cases SHORT COMMUNICATIONS

Allergic contact dermatitis due to amcinonide

( + / + + ), aluminium subacetate I% aq. (+I++). Later still, the patient was tested intradermally with 0.05 ml aluminium hydroxide (AI(OH)3) in 0.5% sodium chloride, which gave a positive reaction after 1 day which did not disappear until 7 days. 1 month later, we patch tested the patient again with the GIRDCA standard series, using different patch test units (Curates!) and obtained the following positive results: cobalt chloride (+I+ +) and Disperse Yellow 3 (+I++). The history showed that the patient had been exposed to aluminium salts at work; in fact careful enquiry revealed that a component of abrasive products used for burnishing marble consisted mainly (95.2 to 99.2%) of aluminium oxide (Alp3).
