摘要:

The correct concentration and vehicle for patch Letting with corticosteroids is in many instances not known. Tine results of this study Suggest that 1% in ethanol should be the initial choice, unless it can he shown that petrolatum as a vehicle is as sensitive (tixocortol pivalate and budesonide). We could find no evidence for the anti‐inflammatory effects of corticosteroids inhibiting the patch test al higher concentrations. Using ethanol as the vehicle resulted in reactions developing at earlier time points than with petrolatu

摘要:

3 dyes, Solvent Yellow 124 and Solvent Blue 79 or Solvent Blue 98, were added to diesel oils in Sweden for identification of their particular use and taxation bracket in late 1993. Health concern regarding the toxicity of the dyes resulted in several reports to the Worker Inspection Bureau. 36 men reporting skin disease supposedly caused by dyes were diagnosed to have irritant reactions, irritant contact dermatitis or exacerbation of other skin disease. Tests on 15 individuals from this group, and 20 healthy volunteers, failed to demonstrate contact allergy or contact urticaria to the dyes or dyed diesel oil. Patch tests with dyes (10% v/v) in pet, did not cause irritation. Tests of irritant properties of the diesel oils showed that the old type of oil, with high viscosity, high content of aromatic compounds and moderately high sulfur content, caused little irritation, whereas newer, lighter qualities of diesel oil, with low concentrations of aromatic compounds and low sulfur content, which cause less pollution to the environment when burnt, were significantly more irritant to the skin and probably a cause of the skin problems.

摘要:

The age‐ and sex‐related distribution of positive patch lest reactions was investigated in 234 children (0–7 years,n=72 and 8–14 years,n=162), 1200 adults (20 to 50 years) and 295 elderly patients (≥70 years) with suspected allergic contact dermatitis using a European standard series. In girls Prom 0 to 7 years, the most frequent contact allergens were thimerosal (37.5%) and nickel (27.5%), in girls from 8 to 14 years, nickel (28.7%) and thimerosal (26.6%), in women, thimerosal (25.3%) and nickel (25.2%), and in elderly women, nickel (12.6%) and balsam of Peru (9.7%). The most frequent contact allergens in boys from 0 to 7 years were ethylmercuric chloride (28.1%) and thimerosal (25.0%), in boys from 8 to 14 years, thimerosal (30.9%) and ethylmercuric chloride (14.7%), in men, thimerosal (21.1%) and ethylmercuric chloride (13.7%) and in elderly men, nickel (11.2%) and balsam of Peru (6.7%). Females showed more positive reactions than males. Whilst 0 to 7 year‐old girls and boys showed relatively more frequent reactions, the elderly of both sexes were clearly less affected. Nickel is the most frequent contact allergen in females of 8 years and more. In men, thimerosal is most frequent and reactions to balsam of Peru show a peak incidence in the elderly. Results indicate that patch testing should be considered in children and elderly patients with appropriate

摘要:

397 patients claiming various subjective symptoms related to dental restoration materials have been tested for the presence of metal allergy. The resultant data have been com pared with the corresponding allergies of eczematous patients. The frequency difference of metal allergy in the dental group is statistically significant or close to significance for nickel sulfate, potassium dichromate, cobalt chloride, palladium chloride and gold sodium thiosulfate. The findings suggest that the dental patient group represents a subgroup with a high frequency of metal allergy.

摘要:

We report a patient with occupational contact dermatitis due to sensitization to mancozeb and perhaps metiram used in a vineyard. Patch testing showed strong allergic patch test reactions to 2 of the commercially available preparations used (Dithane Ultra® and Polyram WG®). Further patch tests showed allergic patch test reactions to mancozeb (0.5 and 1% pet.) as weak reaction to metiram (1% pet.) as well as to 4 other fungicides of the dithiocarbamate group (maneb, nabam, propineb and zineb), which had never een used in the vineyar

摘要:

12 cases of occupational allergic contact dermatitis caused by decorative plants were diagnosed in a 14‐year period. The patients were middle‐aged, and their average exposure time was 13 years. The plant families and plants causing occupational contact dermatitis were Compositae (5 patients: chrysanthemum, elecampane, gerbera, feverfew), Alstroemeriaceae (5 patients,Alstroemeria), Liliaceae (4 patients; tulip, hyacinth). Amaryllidaceae (2 patients: narcissus) and Caryophyllaceae (2 patients; carnation, cauzeflower). The known chemical allergens causing dermatitis were tuliposide‐A and sesquiterepene lactones, such as alantolactones and parthenolide, in the Liliaceae and Compositae families. 7 of the 12 patients were able to continue their work; 5 were not because of severe relapses of skin symptoms. The plant allergen and extract series currently available are of great help in the diag

摘要:

A survey of occupational dermatoses, based on a questionnaire, clinical examination and patch testing, was curried out among 341 workers in an aircraft plant. The questionnaire was answered by 330 workers (96.8%), Present or previous skin disease was reported by 92 employees, who were all subjected to physical examination and patch testing. Patch testing was conducted with a standard series, us well as with a series of substances and products representing the work environment. Occupational contact allergies were established in 12 employees. In total, the figure for occupational skin diseases was 16.1% (55 workers), when calculated for all employees.

摘要:

92 children (45 girls, 47 boys), mean age 9.3 years (3‐14.75), were referred to the Contact Dermatitis Investigation Unit, Belvidere Hospital, Glasgow, for patch testing during the period 1979–93 for the investigation of allergic contact dermatitis (ACD). The diagnoses at the time of referral were atopic dermatitis (45). non‐atopic with localized dermatitis (26), juvenile plantar dermatosis (15), orofacial granulomatosis (2), vaccination reaction (2) and atypical psoriasis (2). In total, there were 55 positive reactions in 30 children. The commonest allergens were metals (18), fragrances (11) and rubber compounds (6). The patient groups with the highest yield of positive patch tests were those patients with atopic dermatitis who had a good history of a precipitating contact factor (4/5), and non‐atopic patients with dermatitis of hands and/or feet (7/14). Our findings suggest that allergic contact dermatitis is more common in children than generally appreciated and that patch testing is a practicable and clinically worthwhile procedure in c

摘要:

100 consecutive patients routinely attending the contact dermatitis clinic were patched tested to gold sodium thiosulfate (GST). 13 patients had a positive patch test to GST, 11 of whom were female, and 12 had pierced ears. There was no correlation with any other substance in the European standard series, although there was a high incidence of nickel sensitivity in all patients (33%). Eczema on the ring fingers and neck was significantly more common in the group positive to GST. 1/2 of the patients with a positive response to GST had symptoms that they felt could he attributed to gold allergy.

摘要:

Jelutong is the wood fromDyera costulatagrowing in south‐east Asia. It is soft and easy to work and is used in. e.g., model workshops in car factories. It has also been much used in woodwork leaching in Swedish comprehensive schools. To estimate the prevalence of contact allergy to jelutong, 84 woodwork teachers and 110 consecutive dermatitis patients were patch tested with extract from wood dust of jelutong. 16/84 (19%) teachers had positive reactions. When they were tested with a dilution series, positive reactions were obtained for 6 mg and down to 0.3 mg of the extracted material. Half the test‐positive teachers had skin symptoms that, might he related to exposure to jelutong, 4/110 dermatitis patients at the clinic also had positive reactions, and possible exposure to jelutong was traced in 3 of them. 3 other dermatitis patients had flare‐up reactions after about 2 weeks, indicating patch‐test sensitization. To investigate the sensitizing capacity of the extract, the cumulative contact enhancement test was performed in guinea pigs. This confirmed that the extracted material was sensitizing, and a clear dose‐response relationship was found. The schools will be recommended to use safer wood alternatives in woodwork
