BACKGROUND There are no studies on contact allergy in patients with prurigo. With itch being important in the pathophysiology of prurigo diseases and being a symptom of allergic contact dermatitis, we aimed to investigate contact allergy in patients suffering from prurigo. OBJECTIVES Exploratory analysis of patch test results in prurigo patients. MATERIALS AND METHODS A retrospective analys...

BACKGROUND Isolated cases of allergic contact dermatitis, gingivitis and stomatitis caused by beryllium have been previously reported. We have been able to study a series of 12 patients with patch test reactions to beryllium chloride. OBJECTIVES The study was aimed at defining the clinical and patch testing characteristics in this group of patients, and determining whether some were delayed e...

Evidence for the effectiveness of patch testing and the need for an expanded series that provides experience and evidence-based suggestions for an extended patch testing series are examined in this review. Many of those testing with shorter allergen series are interested in expanding the spectrum of patch testing. The American Contact Dermatitis Society (ACDS) Core Allergen Series Group has arr...

This publication presents the specialists’ experience of Nizhny Novgorod State Technical University n.a. R.E. Alekseev (NNSTU) in field studying friction-rolling an automobile wheel on asphalt surface. Adequate mathematical reproduction force reactions that occur contact patch plays a significant role modeling vehicle dynamics. Since fundamental description this interaction is difficult, engine...

Parabens, methyl, ethyl, propyl, benzyl, and butyl, are the most common preservatives in use today. They are the alkyl esters of p-hydroxybenzoic acid and are used extensively because they are relatively nonirritating and nontoxic and offer good antimicrobial coverage. Testing for paraben allergen can be done by patch testing. Two cases of allergic contact dermatitis (ACD) to parabens are used ...

BACKGROUND Contact sensitization to fragrances is common both in clinical and in population samples. The spectrum of allergens is broad and diverse, and to some extent covered by a set of screening agents. OBJECTIVES To examine the current frequency of contact sensitization to fragrance allergens in patients routinely patch tested for suspected allergic contact dermatitis with the baseline se...

Allergic contact dermatitis due to fragrances usually manifests as subacute or chronic dermatitis because fragrances are found in a wide range of products to which patients are repeatedly exposed. The typical patient is a middle-aged woman with dermatitis on her hands and face, although other sites may be affected depending on the allergen and the product in which it is found. The standard patc...

An 11-year-old girl presented with a history of two episodes of facial eczema, which developed 1 day after the application of make-up that was removed with ‘hypoallergenic’ facial wipes. She was patch tested with the British Society for Cutaneous Allergy baseline series, a facial series (Chemotechnique Diagnostics, Vellinge, Sweden), and the facial wipes (the only ‘own’ product made available f...

Few published reports have described occupational contact dermatitis from proton pump inhibitor (PPI) exposure in the literature. We present an additional case of a 58-year-old male pharmaceutical worker with an occupational airborne allergic contact dermatitis to PPIs confirmed by patch testing. This is a novel report of workplace exposure to dexlansoprazole and esomeprazole PPIs with resultan...
