“Introduction Among the various substances known to cause occupational allergic contact dermatitis, additives to rubber comprise a conspicuous and meaningful subgroup. The additives are either remnants from the production process, e.g., vulcanisation accelerators, or added to enhance the technical properties of the final product, such as plasticisers, colours, antioxidants or antiozonants (Belsito 2000). The thiurams are regarded
as the most important class of contact allergens among the vulcanizers, partly due to cross-reactivity (-allergy) with corresponding dithiocarbamates, which are used for similar purposes. Enzalutamide order Patch testing is performed with a screening mix of tetraethylthiuram disulphide (CAS 97-77-8), tetramethylthiuram monosulfide (CAS 97-74-5), tetramethylthiuram disulphide (CAS 137-26-8) and dipentamethylenethiuram NVP-LDE225 datasheet disulphide (CAS 94-37-1) at 0.25% each, i.e., a total concentration of 1% incorporated into petrolatum as carrier. The thiuram mix is part of all national and international standard series known to us. Hence, virtually all patients who are patch tested are
exposed to the thiuram mix. Such general diagnostic application enables
the analysis of occupational (and other) risk factor not biased by selective application of the allergen to certain subgroups of patients undergoing patch testing––notwithstanding the issue of selection from the (working) population into the group of patients patch tested (see “Discussion”). Data collected by the Information Network of Departments of Dermatology (IVDK, www.ivdk.org) was retrospectively analysed, regarding the association between contact isometheptene allergy to the thiuram mix and occupational exposure and other important factors, respectively. Methods The IVDK, a contact allergy surveillance network in Germany, Switzerland and Austria, has been described elsewhere. Briefly, results of all patients patch tested in the participating departments are electronically recorded, along with important demographic and clinical data. The diagnostic procedure follows international guidelines (Wahlberg and Lindberg 2006) further refined by the German Contact Dermatitis Research Group (Schnuch et al. 2008), of which all IVDK participants are members. All data are transmitted to the data centre in Göttingen in an anonymous format twice yearly, where it is checked and, if satisfying internal quality control criteria (Uter et al. 2005), analysed according to international guidelines (Uter et al. 2004b) using SAS™ software (version 9.2, SAS Institute, Cary, NC).
