The preservative methyldibromo glutaronitrilc (MDBGN) is used non-occupationally and occupationally. High contact allergy rates have been reported when tested in consecutive dermatitis patients as well as clinical cases with allergic contact dermatitis. Up till now there has been no agreement on which patch test preparation to use to trace contact allergy to MDBGN. From the year 2005 on, MDBGN ...

Abstract This paper examines policy effectiveness as a function of leader identity. We experimentally vary religious identity in coordination game implemented India and focus on citizen reactions to identity, controlling for actions. find that minority leaders improve coordination, majority do not.

Contact dermatitis is produced by external skin exposure to an allergen, but sometimes a systemically administered allergen may reach the skin and remain concentrated there with the aid of the circulatory system, leading to the production of systemic contact dermatitis (SCD). Metals such as nickel, cobalt, chromium, and zinc are ubiquitous in our environment. Metal allergy may result in allergi...

Hydrogen diffusion during rolling contact fatigue (RCF) is considered a potential root cause or accelerator of white etching cracks (WECs) in wind turbine gearbox bearing steels. Hydrogen entry into the bearing steel during operation is thought to occur either through the contact surface itself, or through cracks that breach the contact surface, in both cases by the decomposition of lubricant t...

ost primary care physicians see a large number of patients each year ith eczematous skin diseases. Although many of these patients have topic eczema, another extremely common cause of eczema is contact llergy. This subgroup of eczema patients is notably resistant to treatment nless the causative allergens can be identified and eliminated. It is stimated that allergic contact dermatitis (ACD) to...

BACKGROUND Photocontact dermatitis to Ficus carica is induced by furocoumarins present in sap. These substances are generally considered to cause phototoxic reactions. OBJECTIVES We conducted a patch test and histopathological study of patients with phytophoto contact dermatitis from the fig tree to evaluate the mechanism underlying the photoreaction. PATIENTS AND METHODS Patch and photopat...

A 15-year-old boy developed contact dermatitis after a foot injury treated with diclofenac. Two years later he ingested diclofenac p.o. for pain relief after exercise. The following day he showed a generalized eczema, fading away during the next two weeks. Subsequently paracetamol was well tolerated but had no sufficient analgetic effect. Patch testing was performed with different nonsteroidal ...

BACKGROUND Some toothpastes, cosmetics and ointments contain propolis, a bee product, and it is increasingly popular as a dietary supplement. Although propolis is known to cause contact allergy, there have been no studies of the prevalence of this. OBJECTIVES This study aimed to determine the prevalence of contact allergy to propolis in beekeepers and any relationship between propolis allergy...

BACKGROUND Reviews on irritant and allergic airborne contact dermatitis have been previously reported in the literature. MATERIALS AND METHODS Here, we present an update based on recently published airborne-induced skin reactions. For this survey, we screened the journals Contact Dermatitis, Dermatitis, and included relevant articles from other journals during the period January 2007 to Decem...

MCI: methylchloroisothiazolinone MI: methylisothiazolinone INTRODUCTION Methylisothiazolinone and methylchloroisothiazolinone (MI/MCI) are broad-spectrum preservatives widely used in cosmetics and household and industrial products. It is well known that MI/MCI can cause allergic contact dermatitis with a spongiotic reaction pattern. Because of this reaction, restrictions have been placed on the...
