Contact dermatitis lasted longer than 1 week. The necklace consisted of 42 brown wooden beads and 63 other wooden parts, 0.5 to 3 cm diameter.

Exposure to wood dusts may cause various skin and mucosal symptoms. Allergic dermatoses, caused by wood dusts, diagnosed at the Finnish Institute of Occupational Health during 1976-1999 are reported here. 16 had allergic contact dermatitis and, 2 had contact urticaria. 9 men (3 cabinet makers, 3

A novel high-performance liquid chromatographic/ultraviolet method was developed to detect lapachol (LP) and deoxylapachol (DLP) in wood dust as chemical markers of teak wood (a suspected human carcinogen). The specificity of this analysis was determined by noting the absence of LP and DLP in 12

Experimental studies on the sensitization capacity of naturally occurring naphthoquinones derived from plants and woods have been carried out with 6 compounds. With 4 of these substances (desoxylapachol, menadione, lapachenole andmacassar quinone) guinea pigs could be sensitized. Desoxylapachol,

Numerous epidemiological studies have shown that occupational exposure to wood dust can induce several respiratory diseases such as allergic rhinitis, chronic bronchitis, asthma, and sino-nasal adenocarcinoma. However, comparison of the harmful potential of different wood dust species on the basis

Various adverse cutaneous reactions may occur as a result of exposure to wood dust or solid woods. These include allergic contact dermatitis, irritant contact dermatitis and, more rarely, contact urticaria, photoallergic and phototoxic reactions. Also cases of erythema multiforme-like reactions have

BACKGROUND Sensitization to pollen and spores of the Southeast Asian tropical region is not well documented. This study evaluated the allergenicity of the tropical airspora in Singapore. METHODS On the basis of the results of an aerobiologic survey of the airspora profile of Singapore, crude
