A retrospective study of Patch test results from 163 patients with stasis dermatitis or leg ulcers. I. Discussion of the Patch test results and the sensitization indices and determination of the relevancy of positive reactions
Patch test results from 163 patients with leg ulcers and/or chronic venous insufficiency, tested with a modified ICDRG standard test battery and a pharmaceutical test series, are analyzed and compared with the results obtained from a randomly selected control group of patients with eczematous conditions. A sensitization index for the most common contact allergens present in this test series is calculated, and the relevancy of hypersensitivity to specific topical agents is determined.
