Occupational allergic contact dermatitis in beauticians

We patch tested 13 beauticians with hand dermatitis between 1982 and 1986. They were all young female novice beauticians or those in training. The onset of their allergic dermatitis was noticed within 1 month to 1 year of their starting this occupation. Definite positive reactions to products were seen from hair dyes (as is, open test) (6/12), cold permanent wave primary solutions (as is, open test) (7/13) and a shampoo (1% aq., closed test) (1/13). Positive reactions to allergens were seen with para‐phenylenediamine (1% pet) (12/13), ammonium thioglycolate (5% aq., open test) (3/7), para‐toluylenediamine (1% pet) (7/9), para‐aminophenol (1% pet) (1/4), ortho‐aminophenol (1% pet) (1/4), Quinoline yellow SS (0.5% pet) (1/4), nickel sulfate (2.5% pet) (1/12), cobalt sulfate (2.3% pet) (1/12), thimerosal (0.05% pet) (1/12) and procaine hydrochloride (1% pet) (1/12). Study of the prognosis showed that 5 out of 12 cases could continue their occupation, but 4 cases had persistent hand dermatitis despite protecting their hands from hair dyes with gloves, 7 cases quitted their jobs, and in 5 their hands healed while 2 cases continued to have atopic hand dermatitis. A personal or family history of atopy was frequent among the cases, so we recommend that those who have such a history should not become beauticians.

Airborne pigmented contact dermatitis due to musk ambrette in incense

We reported 2 patients with pigmented contact dermatitis caused by occupational airborne contactants, whitening dyes in clothes and formaldehyde in packing adhesive tapes. A woman developed airborne pigmented contact dermatitis due to musk ambrette in incense. Patch testing confirmed the diagnosis. Since olden times, people in Japan have burnt incense when they worshipped their ancestors. Recently, it has been in fashion to enjoy perfumes and people may burn incense all day long every day. Our patient burnt 2 kinds of incense every day for about 5 years. We assumed musk ambrette was volatilized when incense was burnt, and contact on her face being dissolved in sebum, thus inducing allergic pigmented contact dermatitis.

Is sesamaol present in sesame oil

Sesame oil has been reported to contain sesamolin, sesamin and sesamol as contact allergens. A female patient had chelitis due to sesame oil in a lipstick. She reacted to sesamolin and sesamin, but not to sesamol. We earned mil analysis of the sesame oil by high performance liquid chromatography. We detected sesamolin and sesamin but not sesamol in sesame oil.

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

Pigmented contact dermatitis due to musk moskene.

Musk moskene is a soft, sweet fragrance resembling musk ambrette which introduces a very desirable creamy powder note for cosmetic fragrance. Because of its advantages, which include low cost, oil solubility, and less sensitive to sunlight, musk moskene has recently increased its share of the market.

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).
