BACKGROUND Linalool is a commonly used fragrance terpene that forms potent sensitizers upon oxidation. In a recent multicentre study, we found that 7% of 2900 patients showed positive patch test reactions to oxidized linalool at 6.0%. No elicitation studies have been performed. OBJECTIVE To identify threshold concentrations for elicitation of allergic contact dermatitis caused by oxidized lin...

The contact behaviour between the grinding wheel and workpiece in abrasive machining processes has been investigated. This has revealed the ambiguity in deciding the size of the contact region from a measured contact signal. For improved representation of the contact conditions, fuzzy set theory was used. A membership function for the fuzzy representation of the extent of wheelworkpiece contact...

OBJECTIVE The patch test (PT) with its modification - the strip patch test (SPT) - is the standard in vivo procedure to diagnose an allergic contact dermatitis (ACD). To date, none of the in vitro tests for the diagnosis of ACD fulfils the requirements of an easy, valid and reliable test. To investigate the prediction ability of a flow cytometric assay of CD69 up-regulation on CD4+ CLA+ T cells...

reactions, 5 had a history of atopic dermatitis. While some authors sustain that allergic contact dermatitis is less common in patients with such a history, others claim that it is equally common, and still others claim that it is more common.7 Whatever the case, we believe that patch testing could be a useful diagnostic aid in children with foot dermatitis, of allergic or other origin, in whom...

BACKGROUND Atopic dermatitis (AD) is a chronically relapsing dermatitis with no known cure. Due to the chronic nature of the condition, frequent and long term topical therapy is used. This may lead to sensitization, resulting in allergic contact dermatitis (ACD). AIMS The aim of the study was to observe the frequency of ACD in atopic patients in this part of the country using Indian standard ...

306 eye care/cosmetic products should also be tested. Though phenylephrine is widely used by ophthalmologists in India in nonhypertensive adults as a mydriatic agent to obtain maximum pupillary dilatation prior to fundus examination and assessment of refractory errors, allergic contact dermatitis has not been reported from this country so far. This may be partly due to a low index of suspicion ...

BACKGROUND Footwear dermatitis represents a common but often undiagnosed or misdiagnosed condition. Patch testing aids in its confirmation and identification of the offending allergen. AIMS This study aimed to find the frequency of positive patch test reactions in cases with suspected allergic contact dermatitis (ACD) to footwear, as well as the common responsible allergens. MATERIALS AND M...
