BACKGROUND
Recalcitrant non-actinic cheilitis may indicate contact allergy.
OBJECTIVE
This study aimed to determine the prevalence of allergic contact cheilitis (ACC) in patients with non-actinic cheilitis and to identify the most relevant allergens.
METHODS
We used an institutional database to
8 alkyl gallates, including the widely used antioxidants propyl, octyl, and dodecyl (= lauryl) gallate, have been subjected to experimental sensitization in guinea pigs. Using a modern sensitization procedure, the results showed that all gallates are moderate to strong contact sensitizers: dodecyl
Additives are now an established part of our packaged food. Some, like colouring agents and flavouring compounds are hardly necessary or even redundant. Others, mainly antimicrobials and antioxidants, are very important. Antioxidants are not only added to food, but also to cosmetics, pharmaceuticals
Allergic contact dermatitis related to cosmetic use can result from allergens not routinely evaluated by standard patch test protocols. Propyl, octyl, and dodecyl gallates are commonly used antioxidant preservatives with reports of associated allergic contact dermatitis in the literature. The
BACKGROUND
Burning mouth syndrome (BMS) is a burning or sore mouth in the absence of changes in the oral mucosa. It is often difficult to diagnose and treat. Numerous theories of the etiology have been suggested, including contact allergy.
OBJECTIVE
To determine the clinical utility of patch testing
From April 2001 to December 2002, a group of 514 patients (178 men, 336 women, average age 42.8 years) suffering from chronic eczema were tested by means of epicutaneous tests for contact hypersensitivity to selected auxiliary substances of dermatological external and cosmetic preparations. In 194
BACKGROUND
Since 1947, the cosmetics, pharmaceutical, and food industries have used gallates as antioxidants to prevent the oxidation of unsaturated fats in their products. The aim of this study was to review the cases of sensitization to gallates diagnosed in our department between 1985 and
BACKGROUND
Some patients may have delayed allergic patch test reactions that are not identified with a typical 5-day reading protocol.
OBJECTIVE
To identify allergens with delayed-positive reactions and to determine whether a late reading (day 7-9) can be substituted for the day-5
