Patch testing is essential for identification of culprit allergens responsible for allergic contact dermatitis. This manuscript reviews how to perform patch testing and how to read and interpret the results.
If a developer commits a patch that breaks the build (i.e., that does not compile or causes tests to fail), the given patch should be backed out in order to keep the repository stable while the developer writes a fix. In 2011 Firefox adopted rapid release cycles and changed its code integration model. Previously, developers committed code to the central repository off which patches branched; in...
BACKGROUND Patch testing has previously been shown to influence the quality of life, although a very few studies have shown if this is dependent on the result of the patch tests. OBJECTIVE To assess the impact of patch testing on the quality of life (QOL) in patients with hand eczema (HE). METHODS A total of 50 patients diagnosed of hand eczema at the time of patch testing, aged 16 years an...
The present guideline summarizes all aspects of patch testing for the diagnosis of contact allergy in patients suspected of suffering, or having been suffering, from allergic contact dermatitis or other delayed-type hypersensitivity skin and mucosal conditions. Sections with brief descriptions and discussions of different pertinent topics are followed by a highlighted short practical recommenda...
Atopy patch testing with Japanese cedar pollen extract has been used to investigate patients with atopic dermatitis whose condition is exacerbated by contact with Japanese cedar pollen. Comparative atopy patch testing, scratch tests, and assays for total IgE and specific IgE were performed in 74 patients with atopic dermatitis, 5 patients with Japanese cedar pollinosis and 15 control subjects. ...
INTRODUCTION Persistence of allergen and immunocompetent cells at sites of healed contact dermatitis has been reported. Flare-up reactions triggered by patch testing and after systemic provocation with allergen are well-known phenomena. To our knowledge, we report the first flare-up of a previous patch test site following casual cutaneous application of nickel in an individual with hitherto lat...
In evaluation of medication allergy, the utility of drug patch testing is dependent on both the type of drug reaction and the suspected causal drug. Epicutaneous patch tests reproduce T cell-mediated delayed hypersensitivity; thus, eruptions at least partially mediated by T cells can be confirmed by positive drug patch test (DPT) responses in some patients. These include acute generalized exant...
Background: Job-related allergic contact dermatitis (ACD) mayprolong the disease duration, increase disabilities, and decreasethe patient’s quality of life. The aim of this study was to determinecommon allergens causing ACD, investigating certain featuresof the disease and evaluating its relation to the patients’ jobs.Method: In this cross-sectional study, relevant data was obtainedfrom patch t...
A previous survey on the practice of diagnostic patch testing among representatives of member societies of the World Allergy Organization (WAO) has, in some countries, not addressed those stakeholders actually involved in patch testing, mainly dermatologists. The need for further standardisation is acknowledged and has been addressed e.g. by publication of a patch test guideline by the European...
Local anesthetics are widely used in clinical practice, and adverse effects are not uncommon. Delayed hypersensitivity reactions are among the most common effects, but immediate-type reactions may also occur. Patch testing should be considered in patients with hypersensitivity reactions. We present a case of allergic contact dermatitis to benzocaine that was detected incidentally by patch testi...
