rove beetle dermatitis produced by the family staphylinidae genus paederus has world- wide distribution some one hundred species of paederus have been found, but it is believed that only 30 of these produce dermatitis. up to 1976 three species of paederus have been found in iran as: p. fusciped curtis; p. pietschmanni bershaner , and p. spectabilis kraatz . observations on the biology of paeder...

BACKGROUND Urticarial dermatitis may represent a useful term for a subset of a reaction pattern designated most commonly as dermal hypersensitivity by pathologists. The term is not commonly used, and requires definition to determine whether it is clinically relevant. OBJECTIVES To define urticarial dermatitis and distinguish it from other urticarial reaction patterns and to review the frequen...

BACKGROUND Atopic dermatitis is the most common chronic inflammatory skin disease. A complex interaction of both genetic and environmental factors is thought to contribute to the disease. AIMS To evaluate whether single nucleotide polymorphisms in the TLR2 gene c.2258C>T (R753Q) (rs5743708) and TLR2 c.-148+1614T>A (A-16934T) (rs4696480) (NM_0032643) are associated with atopic dermatitis in Tu...

Atopic dermatitis/eczema is a chronically relapsing, pruritic, and inflammatory skin disease. The term "atopic eczema/dermatitis syndrome" covers the "extrinsic" and "intrinsic" atopic dermatitis. The pathogenesis of atopic dermatitis includes complex interaction between the genetic background, skin barrier defects, abnormalities in innate and adaptive immunity, abnormalities of humoral and cel...

Background: Eczema or atopic dermatitis (AD) is one of the most prevalent skin diseases in the world. Although, the disorder is not fatal, it can cause life quality reduction. The aim of the current study was to investigate the impact of atopic dermatitis on life quality of 1-6-year-old children. Materials and Methods: The current study is a descriptive and analytical one designed to assess qu...

BACKGROUND Atopic dermatitis is a chronically relapsing inflammatory skin disease. Animal models induced by relevant allergens play a very important role in the elucidation of the disease. The patients with atopic dermatitis are highly sensitized with mite allergens such as Dermatophagoides farinae (Df). Therefore, in the present study, we tried to develop a novel model for atopic dermatitis by...

Contact dermatitis is a common inflammatory skin condition characterized by erythematous and pruritic skin lesions that occur after contact with a foreign substance. There are two forms of contact dermatitis: irritant and allergic. Irritant contact dermatitis is caused by the non-immune-modulated irritation of the skin by a substance, leading to skin changes. Allergic contact dermatitis is a de...

A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermat...

BACKGROUND Hand dermatitis is a common chronic relapsing skin disease resulting from a variety of causes, including endogenous predisposition and environmental exposures to irritants and allergens. Lifestyle factors such as smoking have been implicated in hand dermatitis. OBJECTIVE To evaluate the association between tobacco exposure and hand dermatitis using the 2003~2004 National Health and...

BACKGROUND Atopic dermatitis is a chronic or chronically relapsing, pruritic inflammatory skin disease. The incidence of atopic dermatitis has dramatically increased during the past three decades in industrialized countries. We attempted to develop an improved method to induce an animal model of atopic dermatitis and to use it to evaluate the efficacy of a Tec family kinase inhibitor. METHODS...
