Acne vulgaris: myths and misconceptions among patients and family physicians.

The objective of the study was to evaluate the health beliefs and knowledge about acne among acne patients and family physicians. A total of 100 patients referred to a dermatologist for management of acne vulgaris and 120 family physicians completed questionnaires. The questionnaires consisted of questions about health beliefs, the natural course of the disease, the causes of acne, and a set of questions about the knowledge of acne therapy. Acne was considered as a trivial and transitory condition by 52% of the acne patients and 44% of the family physicians. The overall score of correct answers pertaining to the causes of acne among the acne patients and family physicians was 11 and 15%, respectively. The percentage of correct answers regarding the natural course of the disease was 6% for both subsets of subjects. Acne was believed to be curable by 96% of acne patients. Most patients (66%) believed that acne would improve immediately after the first treatment. The knowledge of isotretinoin teratogenecity was reasonable among family physicians (55% correct answers), but it was much lower for other side effects (9%). The overall score of correct answers regarding antibiotic therapy among family physicians was only 21%. Impact of the disease was underestimated by family physicians and also by acne patients. Overall knowledge pertaining to the causes, natural course and therapy was very low. Myths and misconceptions still exist among patients but also among family physicians.
