Sir, Allergic contact dermatitis caused by topically applied agents is a problem that physicians seek to avoid during the treatment of skin diseases. In this report, we present a case of allergic contact dermatitis caused by luliconazole, an imidazole anti-fungal drug. Patch testing suggested that luliconazole sensitivity might have been attributable to its dithioacetal structure and revealed t...

A 35-year-old male was referred because of eczema on the arms and lips that occurred episodically. He worked in a drug-manufacturing plant, and noticed that the episodes of eczema coincided with the production cycles of thebaine (CAS no. 115-37-7) and oripavine (CAS no. 467-04-9), but not with the production cycles of morphine (CAS no. 57-27-2) and noscapine (CAS no. 128-62-1). The eczema start...

INTRODUCTION Black-spot poison ivy is an uncommon clinical manifestation of contact with Toxicodendron plants. Unlike allergic contact dermatitis, which typically manifests in sensitized individuals within 2448 hours, the black lacquer that results from oxidation of the oleoresin after contact with the plant develops within hours of exposure and precedes allergic contact dermatitis, in some cas...

BACKGROUND Background: Patch tests are an efficient method to confirm the etiological diagnosis of allergic contact dermatitis. OBJECTIVES 1) To determine the permanence of results between two tests performed with an interval of at least one year, in patients with allergic contact dermatitis; 2) To compare the positive results according to rates of intensity; 3) To evaluate the permanence of ...

The objective of this article is to describe allergic contact dermatitis from sodium isopropyl xanthate, potassium amyl xanthate, and carbamates in a geotechnician, to discuss possible cross-reactions, and to report the widespread use of carbamates and mercaptobenzothiazole in mining processes.

BACKGROUND The widespread use of fragrance-containing products is probably the most important reason for its high impact in allergic contact dermatitis. OBJECTIVES To describe the frequency of contact allergy to fragrance allergens as tested in the standard series, in relation to age, sex and lesion locations. To determine trends in frequency over the years and to study the association betwee...

Contact allergy to and allergic contact dermatitis from methyldibromo glutaronitrile (MDBGN) have frequently been reported. This study was initiated to help determine the optimal patch test preparation for MDBGN. In 51 patients with a doubtful or a positive patch test reaction to at least 1 of 4 test preparations with MDBGN in petrolatum at 1.0% w/w, 0.5%, 0.3% and 0.1%, a repeated open applica...

This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...

They can cause allergic contact dermatitis both in occupational and in non-occupational settings. It affects not only the nail area but also the elsewhere on the hands, and occasionally involves the face, including the eyelids, mainly due to an occupation...
