Anaerobic sealants: still a problem today
No full textAcrylic anaerobic sealants are widely used in engineering and electronic industries. They may induce allergic contact dermatitis of the first three fingers and onycholysis. We report a case of allergic contact dermatitis due to anaerobic sealants and we underline some practical problems connected with the frequency of sensitization, patch-testing and material safety data sheet availability
Managing vulvar lichen simplex chronicus
No full textOBJECTIVE: To develop a flow chart indicting which tests to perform with the aim of helping physicians with the diagnosis, management and treatment of lichen simplex chronicus. STUDY DESIGN: We reviewed the data on vulvar lichen simplex chronicus patients to delineate proper management. RESULTS: Patch test should be added to the series of tests performed to ascertain the causes of vulvar lichen simplex chronicus. CONCLUSION: Among the stimuli that may trigger vulvar lichen simplex chronicus, not only infections and irritating factors but also sensitization must be kept in mind, especially in long-lasting disease
Evaluation of contact sensitization in vulvar lichen simplex chronicus - A proposal for a battery of selected allergens
No full textOBJECTIVE: To determine the role of contact sensitization in vulvar lichen simplex chronicus and to select appropriate batteries of allergens to test. STUDY DESIGN: Between 1993 and 2000, 61 women affected by vulvar lichen simplex chronicus were enrolled to evaluate the role of contact hypersensitivity. All the patients underwent patch tests with the Italian standard series and with a wide battery of allergens (preservatives, perfumes, emulsifiers, medicaments) and products they used routinely. RESULTS: Of the women, 47.5% had at least one positive patch test, and relevant positivities were observed in 26%. The relevant allergens were usually medicaments and preservatives. CONCLUSION: It would be acceptable to reduce the number of allergens tested, in particular omitting the perfume series. Patch tests are a helpful diagnostic tool in vulvar lichen simplex chronicus and improve prescribing practice

A child with "occupational" allergic contact dermatitis due to MCI/MI
No full textKathon® CG is a trade name for a mixture of methylchloroisothiazolinone and methylisothiazolinone (MCI/MI). Occupational allergic contact dermatitis from MCI/MI occurs not only in hairdressers and perfumers, but also in metalworkers, painters and bricklayers, the biocide being present in paints, lacquers, polishes, cleaning agents and construction materials
