Abstract:
The nickel concentrations in urine and other data of a very hypersensitive female patient have been followed during two periods exceeding 30 days each. Only a limited degree of correlation was found between the course of the nickel concentration in urine and the clinical activity of the dermatitis. In order to better evaluate the measure of the correlation and the influence of some other factors upon the activity of the dermatitis, a pathway analysis scheme has been constructed. Consideration of this scheme reveals the need for more extensive data regarding the nickel ion climate in the body.
