Reactions of non-immunologic contact urticaria on scalp, face, and back

Background

This study compared the reactivity of scalp, face, and back to nonimmunologic contact urticants (NICU) to ascertain relative responsiveness.



Methods

Model urticants, benzoic acid (BA) and hexyl nicotinate (HN) with 3 concentrations of each were applied to marked skin of 10 bald males during 6 weeks. One urticant was applied to one side of nasolabial fold, back, and scalp and the other applied to the contralateral side. Reactivity was assessed by visual scores (VS) and biophysical instruments. Subjects ranked skin sensation with a 10-point visual analogue scale.



Results

With 0.25% HN application, upper back ...
