Allergic contact dermatitis due to plants is common. Potentially allergenic plants and plant products are found in many everyday environments, such as the home, the garden, the workplace, and recreational settings. By improving our knowledge of allergenic plant-derived chemical compounds, we will be better positioned to identify novel allergens. We review the most relevant chemical allergens th...

Background: Occupational contact dermatitis, especially in hand, is one of the most common occupational disorders. The present study aimed at evaluating patients with occupational allergic contact dermatitis (ACD) caused by common allergens based on occupation type and disease history. Methods: This cross-sectional study aimed at evaluating the data of the patients with probable diagnosis of AC...

Allergic contact dermatitis affects about 5% of men and 11% of women in industrialized countries and is one of the leading causes for occupational diseases. In an animal model for cutaneous contact hypersensitivity, we show that mice lacking both known cannabinoid receptors display exacerbated allergic inflammation. In contrast, fatty acid amide hydrolase-deficient mice, which have increased le...

Chemicals that were bioassayed by the National Toxicology Program (NTP) and that also produce allergic dermatitis (ACD) in humans were evaluated for their tumorigenic characteristics. The impetus for the study was that most contact sensitizers, i.e., those that produce ACD, and genotoxic carcinogens are chemically similar in that they are electrophilic, thereby producing adducts on macromolecul...

Introduction: Allergic and irritant compounds are frequent in nature, and the environmental allergic factors which can induce or exacerbate eczema are different and often unknown in different areas. The aim of this study was to determine the frequency of contact dermatitis in patients with chronic dermatitis referring to dermatology clinics in kerman. Methods: In this descriptive study, standar...

PURPOSE The aim of study was to determine usefulness of the method of continuous TEWL measurement in the evaluation of skin barrier function in physiological conditions and in allergic contact dermatitis (ACD) and atopic dermatitis (AD). MATERIAL AND METHODS Study was conducted on a group of 86 persons: 48 patients with allergic contact dermatitis, 18 with atopic dermatitis and 20 healthy ind...

The leaves, nuts and sarcotesta of Ginkgo biloba L. (Ginkgoaceae) are used in China not only for medical purposes, but also in ‘health foods’ and cosmetics. Cases of allergic contact dermatitis caused by ginkgo leaves, fruits and nuts have been previously reported (1–3), including occupational contact dermatitis in Central Europe (1). We report a case of allergic contact dermatitis caused by G....

Many patients are currently suffering from nickel (Ni)-induced allergic contact dermatitis (ACD). There have been few Korean studies dealing with the threshold of Ni-induced ACD and quantifying the total amount of Ni in the metal alloys. The aim of this study is to evaluate the amount of Ni leached from metal alloys and Ni contents in metal alloys, and to estimate the threshold of Ni-induced AC...

Allergic contact dermatitis (ACD) is one of the most prevalent occupational skin diseases and causes severe and long-lasting health problems in the case of chronification. It is initiated by an innate inflammatory immune response to skin contact with low molecular weight chemicals that results in the priming of chemical-specific, skin-homing CD8(+) Tc1/Tc17 and CD4(+) Th1/Th17 cells. Following ...

INTRODUCTION This is an epidemiologic study to compare allergic contact dermatitis patients in the private and subsidized clinics. PATIENTS AND METHODS All patients diagnosed to have allergic contact dermatitis in the National Skin Centre from January 1999 to June 1999 were studied retrospectively. RESULTS More private patients were evaluated for allergic contact dermatitis than subsidized ...
