Inhalation of wood dusts can cause immediate and/or late onset asthma, and the list of woods responsible for such reactions is increasing. We report two patients with asthma induced by exposure to the dust of African maple wood (Triplochiton scleroxylon). Type I hypersensitivity to this dust was
The inhalation of wood dust may produce allergic rhinitis, asthma, or contact dermatitis in sensitized patients. We describe a patient with occupational asthma induced by the inhalation of samba (Triplochiton scleroxylon) wood dust. A specific bronchial provocation test was conducted, and the
A 58-year-old man, a carpenter, had been suffering from cough, rhinorrhea, wheezing, dyspnea and ocular itching a few minutes after each exposure to the sawdust of "Ayous" wood (Obeche, Triplochiton scleroxylon) since starting to work on this imported wood in 1998. Although his symptoms improved
OBJECTIVE
Wood dust is a known occupational allergen that may induce, in exposed workers, respiratory diseases including asthma and allergic rhinitis. Samba (obeche, Triplochiton scleroxylon) is a tropical tree, which grows in West Africa, therefore, Polish workers are rarely exposed to it. This
BACKGROUND
Obeche wood dust is a known cause of occupational asthma where an IgE-mediated mechanism has been demonstrated.
OBJECTIVE
To characterize the allergenic profile of obeche wood dust and evaluate the reactivity of the proteins by in vitro, ex vivo and in vivo assays in carpenters with
Two carpenters developed rhinitis, conjunctivitis, bronchial wheezing, and dyspnoea while using obeche (Triplochiton scleroxylon, African maple) at their work while they built saunas. Skin prick tests showed an immediate reaction, specific IgE to obeche was detected in their serum, and bronchial
BACKGROUND
Anaphylaxis after the first exposure to a food allergen is uncommon unless a cross-reaction is present.
OBJECTIVE
To investigate a possible relationship between the fruit Cyphomandra betacea Sendth (commonly known as tamarillo) and the wood of Triplochiton scleroxylon (obeche) in a
BACKGROUND
Wood dust is known to cause allergic occupational asthma and obeche (Triplochiton scleroxylon) is a prominent exponent in this field. However, the knowledge about wood allergens is still limited. The aim of this study was to identify and characterize obeche wood allergens.
METHODS
Obeche
A variety of plant substances may induce contact urticaria and the list of substances responsible for such reactions is increasing. We report eight patients suffering from occupational asthma caused by Obeche wood sawdust. These patients also presented with urticaria when they worked with this wood.
The biological effect of exposure to wood dust depends on its composition and the content of microorganisms which are an inherent element of the dust. The irritant and allergic effects of wood dust have been recognised for a long time. The allergic effect is caused by the wood dust of subtropical
