In patients with definite clinical relevance, 6\/7 had occupational allergic contact dermatitis: 4 hairdressers, 1 hair salon cleaner, and 1 aquarium worker; 1\/7 was bleaching her hair.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Prevalence of 2+ or 3+ APS reactions in this single-center study was higher than that reported by the North American Contact Dermatitis Group, 2015\u20132016, (0.75% vs. 2.85% in our study).
