Abstract |
The list of trees capable of causing morbid disorders is very long. Symptoms attributable to the oak, beech, chestnut, locust, poplar, elm, plane tree, yew, juniper tree, Hungarian fir, alder, Sylvester pine, and European cytisus, have been observed. Pathological symptoms attributable to wood fall into two groups: cutaneous involvement and respiratory involvement. In general, cutaneous involvement is observed when fresh wood is handled. The onset can be marked by such general symptoms as a sickish feeling, nausea, shivering, and low grade fever. Then a local sensation of tension, heat, and burning may appear, followed by increasingly intensive sometimes intolerable, pruritus. At the same time, the lesions will take on a scarlet red hue with painful swelling resembling urticaria. Finally, small vesicles will be seen. All these involvements may be found as isolated cases, or can accompany respiratory symptoms which involve the bronchia and upper air passages. |
