Title: Sensitization to Kathon CG in Geneva and Switzerland. Author: Pasche F, Hunziker N. Journal: Contact Dermatitis; 1989 Feb; 20(2):115-9. PubMed ID: 2706958. Abstract: Between October 1986 and June 1987 we patch tested 420 patients with Kathon CG at 100 ppm and obtained 23 positive reactions (5.5%). The other 5 Swiss university clinics joined our study between January and June 1987 and obtained sensitization rates ranging from 0.7 to 7.5%. The total mean value including Geneva was 3.6%. We did threshold patch testing in 12 patients with the following Kathon CG dilutions: 100, 50, 25, 15 and 7 ppm. We observed progressively diminishing skin reactions, especially below 25 ppm, but we still obtained slight positive reactions in 2 patients with Kathon CG at 7 ppm. Those reactions were relevant because the dermatitis disappeared when the use of Kathon-containing creams was discontinued.[Abstract] [Full Text] [Related] [New Search]
