Background and Aim. Contact dermatitis (CD) is the most prevalent occupational skin disease with a significant impact on quality of life. Patch testing is used for the identification of responsible allergens which may improve protective and preventive measures in the workplace. Herein, we aim to identify the demographic characteristics and occupation of patients with early diagnosis of occupati...

BACKGROUND Contact dermatitis (CD) is a significant problem among nurses. Although there are reports about the prevalence of CD from different parts of the world, data about its frequency in Turkey and about allergic contact sensitization among nurses is insufficient. OBJECTIVE To define the frequency and patterns of allergic contact sensitization and related symptoms in practicing and studen...

Hand eczema (HE) is a common and distressing condition that is perplexing to the patient and the physician alike. To study the frequency and clinical features of hand eczema and to correlate the frequency of atopy and contact sensitization with different clinical features a total of 61 clinically diagnosed patient of Hand eczema were included within a period of one year. Patch test was done in ...

Attempted to evaluate and compare the impact on quality of life of occupational and non-occupational ACD and to identify the most frequently involved allergens. A quality of life questionnaire was applied. We noted moderate impact on the quality of life of both groups, without a statistical difference. Our study corroborates previous general data on the prevalence of nickel sulphate and paraphe...

The allergen-specific IgE antibody was determined in 20 men and 120 women with psoriasis and the results were correlated with a history of current and previous allergic disease. Allergic disease was reported in 21% of the patients, but a positive RAST test was obtained in 44%. In chronic plaque-type psoriasis a positive RAST test was significantly more common (58%) than in active psoriasis (22%...

Hand dermatitis is the most frequently recognized occupational skin disease. Comprehensive understanding of the epidemiology of hand dermatitis is crucial to be able to make a correct diagnosis or give appropriate recommendations for its management. From 1983 to 2002, among those referred to Contact Clinic at National Taiwan University Hospital, a total of 2568 patients were patch-tested. We re...

During the 1994-2003 study period, patch testing was carried out in 1102 subjects (740 female and 362 male, mean age 39.8, range 7-81 years) suspected to have allergic contact dermatitis (ACD). Epicutaneous patch test with a standard series of contact allergens was made by the Institute of Immunology, Zagreb, Croatia, according to the Internationational Contact Dermatitis Research Group (ICDRG)...

BACKGROUND Exposure to nickel, cobalt and chromate are important causes of occupational contact dermatitis. OBJECTIVES To estimate the prevalence of nickel, cobalt and chromate allergy in a population of consecutive patients and to investigate the possible association with individual and occupational risk factors. PATIENTS/METHODS A total of 14 464 patients (67.6% women and 32.4% men) with ...

Background. The Moringa oleifera plant has been implicated for several therapeutic potentials. Objective. To evaluate whether addition of M. oleifera to diet has protective effect against nickel-induced nephrotoxicity in rats. Methodology. Male Wistar rats were assigned into six groups of five. The rats were given oral exposure to 20 mg/kg nickel sulphate (NiSO4) in normal saline and sustained ...

The aim of this study was to observe the cytotoxicity and apoptotic effects of nickel oxide nanoparticles on human cervix epithelioid carcinoma cell line (HeLa). Nickel oxide precursors were synthesized by an nickel sulphate-excess urea reaction in boiling aqueous solution. The synthesized NiO nanoparticles (<200 nm) were investigated by X-ray diffraction analysis and transmission electron micr...
