||Dermal and respiratory sensitization to chromate in a cement floorer
||Aug. 1998, Vol.34, No.2, p.169-176. Illus. 33 ref.
||A 48-year-old floorer, occupationally exposed to cement and with a documented chromate contact dermatitis, reported dyspnoea and wheezing after work. These conditions were demonstrated by self-measured sequential peak expiratory flows. A first bronchial provocation test (BPT) with potassium dichromate led to pronounced and sustained decreases in forced expiratory volume in 1 second and forced vital capacity, accompanied by pruritis, a decrease in arterial PO2, a slight rise in temperature, and peripheral blood leukocytosis. Two years later, a BPT with a lower dose of potassium chromate led to an "early late" reaction accompanied by pruritis. A BPT with dry cement containing 12ppm hexavalent chromium was borderline, and a similar result was obtained after smoking 5 cigarettes laced with 10mg of cement per cigarette. The report shows that a subject with allergic contact dermatitis to chromates may develop a respiratory allergic reaction to an airborne source of this metal. Smoking of cigarettes contaminated with cement may have been a significant factor in the causation or elicitation of these reactions.
