BACKGROUND There are no studies on contact allergy in patients with prurigo. With itch being important in the pathophysiology of prurigo diseases and being a symptom of allergic contact dermatitis, we aimed to investigate contact allergy in patients suffering from prurigo. OBJECTIVES Exploratory analysis of patch test results in prurigo patients. MATERIALS AND METHODS A retrospective analys...

BACKGROUND Patch tests are often used in the clinical diagnosis of metal allergies. In currently available patch tests, high concentrations of metal salt solutions are used. However, diagnosis accuracy can be influenced not only by acute skin reactions to high concentrations of metal salt, but also by skin reactions to other components present in the patch or to pH changes. In this study, we de...

JADASSOHiN OF BRESLAU has been hailed as the originator of the patch-test (Jadassohn, 1896). But it is largely due to the work of Bonnevie (1939) in Copenhagen that the patch-test, particularly when exhibited in battery form, has come to hold its present important place in modern dermatology. Bonnevie also established a tradition for excellence in the technique of patch-testing throughout Scand...

Irritant and allergic contact dermatitis is commonly seen in patients complaining of itching, burning and irritation in the genital area. The aim of this retrospective study was to establish the prevalence of allergic contact dermatitis patients with genital complaints. We followed 33 patients with persistent or recurrent genital redness, itching and burning sensation. Diagnosis was made by his...

BACKGROUND AND AIMS Elimination of allergens/topical medications causing contact dermatitis in venous eczema, which poses a significant problem in its chronicity and treatment, provides the basis for better therapeutic outcome. Our objective was to determine the pattern of contact sensitization in venous eczema patients in Himachal Pradesh (India). METHODS Thirty-four patients (M:F, 31:3) and...

BACKGROUND Para-phenylenediamine (PPD) is the primary patch test screening agent for hair dye contact allergy (HDCA). However, no recent studies have been published that describe the results of reactions to patch tests using PPD and hair dyes in Korea. OBJECTIVE To analyze the results of the patch tests to PPD using the thin-layer rapid use epicutaneous (TRUE) Test system in patients with HDC...

Case report A 32-year-old woman was referred to the emergency department because she developed a skin eruption, pruritis and frisson which have occurred four hours after the intake of 200mg of celecoxib for inflammatory back pain. Physical examination revealed generalized urticaria which was thought to be induced by celecoxib. Therefore, she was prescribed corticosteroid therapy and antihistami...

BACKGROUND Nickel, cobalt and chromium are some of the most common causes of type IV sensitizations and subsequent allergic contact dermatitis. Accurate diagnosis of contact sensitization to these metal salts is made possible through standardized patch testing; however, patch tests with metal allergens may be influenced by meteorological conditions at the time of testing. We aimed to investigat...

OBJECTIVES Mercury allergy is a serious health problem. We investigated the relationship between positive patch test for mercury and sources of mercury exposure, indicated by concentrations in biological samples from healthy medical students. METHODS Patch tests for mercury (Hg-PT) were performed on 580 students. For a group of 55 students with a positive Hg-PT result (Hg-PT(+)) and a referen...

The clinical interpretation and reproducibility of atopy patch tests was studied in 23 selected young adult patients with atopic dermatitis and 25 healthy controls using standard inhalant allergens. Non-invasive measurements were used for objective assessment of test reactions and the participants were retested after 6 weeks. Ten of 19 (53%) evaluable patients with atopic dermatitis had at leas...
