BACKGROUND Photodermatitis is an abnormal response to ultraviolet radiation (UVR). The photoallergic contact dermatitis caused by plant allergens is a serious cause of morbidity in India. Airborne contact dermatitis is the classical presentation of plant-induced dermatosis, which may become difficult to differentiate from chronic actinic dermatitis in chronic cases. The rapid growth of partheni...

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.

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...

A polyherbal formulation, Purim, which has anti-inflammatory and immunomodulatory properties and is a chealeating agent for various toxins in the blood, has been advocated to treat various skin disorders. Purim therapy was effective in treating various types of dermatitis in this open clinical trial. Fifty two patients were treated with Purim for 1 month, out of which forty nine completed the s...

Atopic dermatitis is a chronic inflammatory skin disorder, for which it is difficult to obtain epidemiologic findings. In a previous study, we suggested the following diagnostic criteria for atopic dermatitis in the adult Thai population: visible flexural dermatitis, a history of flexural dermatitis, a rash of more than six months duration and visible dry skin. However these criteria were not v...
