Self-diagnosed dermatitis in adults. Results from a population survey in Stockholm.

In a population-based survey of public health issues in Stockholm, Sweden, self-reported hand eczema, history of childhood eczema, nickel allergy, occurrence of skin symptoms on the face and intolerance to cosmetics and hygiene products, were investigated. A postal questionnaire was sent to 15,000 inhabitants aged 19-80 years. The response rate was 73%. The 1-year prevalence of hand eczema was 8% (females 10%, males 6%). History of childhood eczema was reported by 15% and, of these, 42% also stated positively that they had had hand eczema at some time. Hypersensitivity to nickel was owned to 15% of the females and 3% of the males. Of the nickel-sensitive, 30% reported ever having had hand eczema. The combination of nickel allergy and history of childhood eczema resulted in a cumulative prevalence of hand eczema of 56%. Females reported more hand-washings per day than did males, and a relation between number of hand-washings and hand eczema was found. Self-reported 1-year prevalence of skin symptoms on the face was 14% and, of these, 33% also owned to hypersensitivity to cosmetics. Dermatitis appears to be a common health problem. This fact should be made clear to those who give priority and allocate resources to health problems, e.g., by participation of dermatologists in performing population-based surveys.

Do monoterpenes released from feverfew (Tanacetum parthenium) plants cause airborne Compositae dermatitis?

The Compositae plant feverfew (Tanacetum parthenium) is an important sensitizer in Europe and has been suspected of causing airborne Compositae dermatitis. A previous investigation of substances emitted from feverfew plants detected no sesquiterpene lactones, however, but mainly monoterpenes. The aims of this study were to test whether feverfew-allergic patients were also sensitive to some of the above-mentioned monoterpenes and, if so, to study associations between sensitization patterns, relevance of feverfew allergy and clinical features. 17 patients with + +/+ + + reactions to feverfew and parthenolide were tested with 15 selected monoterpenes and 2 sesquiterpenes. Of the 17 persons, 13 had positive and/or doubtful positive reactions to 1 or more monoterpenes. Only 1 person was allergic to several monoterpenes. Her history of gradually worsening Compositae dermatitis culminating in a probable airborne dermatitis, mimicking photosensitivity, and the disappearance of symptoms upon removal of feverfew plants suggest monoterpenes as a possible contributing factor. Similar associations between doubtful positive monoterpene reactions and clinical patterns, fragrance/colophonium allergy and relevance of feverfew allergy were not established with certainty. In conclusion, sensitization to the sesquiterpene lactones of feverfew is not invariably accompanied by sensitization to its volatile monoterpenes. The presence of monoterpene allergy, however, may contribute to airborne Compositae dermatitis.

55 cases of allergic reactions to hair dye: a descriptive, consumer complaint-based study.

Severe facial and scalp dermatitis following the use of permanent hair dyes has been reported in several cases. Para-phenylenediamine (PPD) is known as a potent contact allergen, and PPD is allowed in hair dye at a concentration of 6%. Hair dye reactions are usually diagnosed by the patients themselves, and adverse reactions to hair dye may not necessarily be recorded by the health care system, unless the reactions are especially severe. Based on this assumption, we suspected that hair dye dermatitis was occurring more frequently than reported in the literature. Consumer complaint-based data were obtained by advertising for persons with adverse reactions to hair dye. Among those responding to the advertisement, 55 cases of severe, acute allergic contact dermatitis were identified. The main symptoms were severe oedema of the face, scalp and ears, and clinically this was often mistaken for angio-oedema. The 55 cases comprised a total of 75 visits to the health service and 5 admissions to hospital. 18 persons had sick leave, which supports the impression of very severe dermatitis reactions. 60% were treated with antihistamine, while 52% were treated with corticosteroids. 29% of the cases were patch tested and all were found positive to PPD. Our data presented here clearly show that PPD and its derivatives in hair dye at the present concentrations presents a significant health risk for the population. Furthermore, the severe acute allergic skin reactions are often misdiagnosed in the health care system. The frequency of allergic contact dermatitis resulting from hair dye is likely to be underestimated. New methods to survey the frequency of adverse reactions should be considered.
