In order to define a standard diagnostic protocol for managing allergic dis-eases in musicians, we conducted a literature search on this topic. The most frequent allergic disease in this special category of workers was contact dermatitis, always described in stringed and wind instruments players, involving the mouth and the hands. No other allergic disease directly related to musical instruments was reported. The most frequently reported culprit substances were: colophony, exotic woods, nickel sulphate, varnishes, and propolis (bee glue). Thus, being contact dermatitis the most frequent disease, a correct diagnostic approach to this problem in musicians should involve, in addition to clinical history and examination, the patch test with a specific panel of substances. Finally, allergy in musicians involves additional problems: the virtual impossibility to avoid the offending substance, and the poor adherence to therapy due to lifestyle. In general, this specific allergologic problem seems to be underestimated, underdiagnosed and, as a conquence, poorly managed.

Contact dermatitis is a frequent skin disorder related to environmental and occupational etiological factors, which could potentially affect all age groups, as well as both genders. The current study is aimed at exploring the patterns of contact sensitization with respect to the population's occupational patterns in Greece. A retrospective analysis was performed in a cohort of 1978 patients from 2014 to 2016. Patients were divided into two categories; blue collars (BlC) and white collars (WhC), as well as detailed occupation was considered. Separation was performed on the basis of their profession, i.e., labor workers and handicraftsmen were sorted to the BlC group, while office employees were sorted to the WhC group. The common allergen in all occupational subgroups was nickel sulphate. The three most prevalent allergens in both BlC and WhC were nickel sulphate 5%, fragrance mix (I) 8%, and Balsam of Peru 25%. WhC males were uniquely sensitized to colophony 20% and formaldehyde 2%, and WhC females were uniquely sensitized to 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and neomycin sulphate 20%. Sensitization to allergens manifested occupation-specific patterns. Allergic contact dermatitis surveillance is of great importance towards the clinical and systematic understanding of the disease, especially with respect to the patient's occupational profile.

The aim of the study was to determine the frequency of contact sensitization in patients with lower extremity dermatitis.. Between the years 2001 and 2007, the authors investigated 462 patients (mean age 49.1 years, 196 men and 266 women) with the eczema/dermatitis localized on their lower extremities, including feet. The patients were investigated with epicutaneous tests of the European Standard Series and also with other special patch tests.. The most frequent allergens were balsam of Peru, 44/462 (9.5%); wool alcohols, 41/462 (8.9%); nickel sulphate, 39/462 (8.4%); propolis, 35/462 (7.6%); fragrance mix, 34 (7.4%) and colophony, 29/462 (6.3%).. In patients with lower extremity dermatitis the frequency of contact sensitization is still high, and therefore investigation with epicutaneous tests should belong to the routine dermatological diagnostic procedure in these patients.

Patch testing is performed to evaluate suspected allergic contact dermatitis. Common wisdom suggests that various allergens cross-react but only a few larger studies have published confirmations of this. The purpose of our study was to identify significant correlations between positive test reactions in a screening series.. A total of 1235 patients undergoing patch testing to the Hermal standard series at the Massachusetts General Hospital, Contact Dermatitis Clinic between 1990 and 2006 were investigated.. Two or more positive reactions were seen in 411 patients (33.3%). Sensitizations to eight pairs of allergens were found to have significant correlation (P

A relevance scoring system for positive allergic patch test reactions is proposed. It refers to current relevance (CR) as well as past relevance (PR). The system was evaluated in adult patients between January 1 and June 30, 1996, and limited to 4 allergens: nickel sulfate, neomycin sulfate, epoxy resin and colophony. Certain methods available for increasing the accuracy of relevance were used in the present study. Practical implications and limitations of using a relevance scoring system are discussed.
