Biotin, a water-soluble B complex vitamin, is possibly involved in chronic inflammatory diseases, although the detailed mechanisms are unclear. In this study, we investigated the effects of biotin status on nickel (Ni) allergy in mice. Mice were fed a basal or biotin-deficient (BD) diet for 8 wk and sensitized with an intraperitoneal injection of NiCl(2) and lipopolysaccharide. Ten days after s...
Nickel allergic contact dermatitis (ACD) has become a more widely recognized disease process over the last three decades in the United States. A subpopulation of ACD patients will manifest with systemic contact dermatitis (SCD). Specifically, those cases of widespread recalcitrant nickel ACD with only partial clinical relief after strict nickel avoidance, suggest SCD. Evidence indicates that ap...
Persistent post-occupational dermatitis is a phenomenon that is well-recognized by occupational dermatologists, but there have been few studies on it. In view of this, we proposed to assess the prevalence of this phenomenon in an English setting and ascertain the characteristics of the patients affected. Using modified criteria adapted from previous studies, details of 1100 patients seen in a c...
The role of contact with nickel-containing coins has been controversial. The aim of our study was to compare the release of nickel from Euro (1 and 2) coins and from Polish coins (2 PLN and 5 PLN) at 4oC and 32oC in an immersion test using artificial sweat according to the EU reference method. Nickel extract was analyzed at 8 time points starting from 1 h up to 168 h. After 7 days of test durat...
A novel spectrometer for the rapid and sensitive detection of liquid phase analytes at trace concentrations is presented. Broad bandwidth supercontinuum radiation was coupled into a linear optical cavity incorporating an intracavity liquid-sample cuvette. Cavity enhanced absorption spectra of trace species covering more than 300 nm were acquired on time scales of milliseconds. Single shot acqui...
BACKGROUND Continual surveillance based on patch test results has proved useful for the identification of contact allergy. OBJECTIVES To provide a current view on the spectrum of contact allergy to important sensitizers across Europe. PATIENTS/METHODS Clinical and patch test data of 19 793 patients patch tested in 2005/2006 in the 31 participating departments from 10 European countries (the...
BACKGROUND Patch testing remains the gold standard method for the identification of the etiologic agent of allergic contact dermatitis. However, it is a subjective, time-consuming exam whose technique demands special care and which presents some contraindications, which hamper its use. In a recent study, we showed that the proliferation assay can suitably replace patch testing for the diagnosis...
