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...

INTRODUCTION Eczematous reactions to type I allergy-inducing antigens are documented in a subgroup of patients with atopic eczema. Yet, the underlying immunological mechanisms are not well understood. MATERIAL AND METHODS To delineate the effect of native pollen grains on human skin of healthy and atopic individuals we performed patch tests (atopy patch test with native pollen grains, PPT). N...

BACKGROUND A new technique, cutaneous field stimulation (CFS), which activates electrically unmyelinated C-fibers, is used to treat localized itch. Its action is similar to that of capsaicin, the pungent agent in hot peppers, which enhances delayed allergic reactions. The aim of the study was to investigate how experimental contact dermatitis responds to CFS. METHODS Twelve patients with cont...

Background. The frequency of contact allergens is often regionally different and hence it regional identification is important for the prevention of allergic contact dermatitis (ACD). Objectives. The aim of the study was to determine the most common contact allergens in the etiology of ACD from 2008-2012 and evaluate their dynamics in comparison with similar studies in the Czech Republic and in...

OBJECTIVES To detect common skin-sensitizing agents among patients experiencing allergic contact dermatitis (ACD). Methods: This was a retrospective study of 152 patients with clinically suspected ACD who underwent patch testing in an allergy clinic at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between January 2012 and February 2015. Of these patients, only 74 (48%) patien...

BACKGROUND This randomized trial was undertaken to investigate the effect of experimentally induced allergy on orthodontic induced root resorption. MATERIALS AND METHODS A total of 30 Wistar rats were divided randomly into test and control groups. Starting from the first 3 days, the rats in the test group were injected intra-peritoneally by 2 mg ovalbumin as allergen and 0.5 mg Alume as adjuv...
