We report a case of a non-atopic, 37-year-old nail technician who developed blisters, itching, scaling, and redness, that is, allergic contact dermatitis (ACD), on the hands and fingers owing to sensitization tomethacrylates and acrylates, in this article called (meth)acrylates, only months after finishing her trainee period. The protective effect of gloves was studied in an in vivo system simu...

We are developing a new, animal-free assay for determination of the sensitizing potential of a substance. The design of this assay is based on current immunological knowledge of the pathogenesis of allergic contact dermatitis. It integrates human dendritic cells and keratinocytes, which are both known to be critically involved in vivo. The read-out system uses molecular responses typically occu...

BACKGROUND Cobalt has been shown to induce mainly asthma, allergic contact dermatitis and hard metal disease. The data on cobalt asthma are mainly based on case reports. AIMS To characterize all the cases of occupational cobalt asthma encountered in a cobalt plant at the time of diagnosis and 6 months later. We also evaluated the incidence of cobalt asthma in different departments on the basi...

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...

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...

I am glad to reply to Goldenberg and Jacob’s observations, whom I thank for the kind attention given to my article. As a preliminary consideration, I wish to reiterate that my paper discussed exclusively the exposure to nickel via food; it didn’t discuss the other routes of systemic exposure. It distinguished allergic contact dermatitis (ACD) from systemic nickel allergy syndrome (SNAS) and, wi...

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.

The induction of contact allergy to fragrance ingredients and the consequent risk of allergic contact dermatitis (ACD) present a human health concern that cannot be ignored. The problem arises when exposure exceeds safe levels, but the source(s) of exposure which lead to induction often remain unclear. This contrasts with the elicitation of ACD, where the eczema frequently can be traced to spec...
