“…The strong involvement of familial inheritance is also noted in patients who display severe inflammatory symptoms [12,13,31,32]. This is especially true for families in which affected individuals are found on both the maternal and the paternal side, although the maternal influence is more important [13].…”

A B S T R A C TAcne is one of the most common dermatologic diseases in the developed regions of the world, affecting a large percentage of the population. Despite the great improvement in the number and quality of studies of the molecular etiology of this disease in the past 3 decades, the detailed molecular pathogenesis and the cause of the large individual variations in severity of skin symptoms remain unknown. The roles of genetic inheritance and special genetic susceptibility and protective factors have been suggested for over 100 years, but their identification and determination started only in the 1990s. To date, only a small number of genetic polymorphisms affecting the expression and/or function of a handful of genes have been investigated. This review surveys the major findings of the classic and molecular genetic studies that have been conducted in this field, draws conclusions, and indicates how the available data help our current understanding of the pathogenesis of this common skin disease. ᭧

Introduction: Acne, is a common disease. Its prevalence is 80% among adolescents in the world and 57,1% in Ouagadougou in 2001 among school pupils. The medical literature is provided on the epidemiological, clinical and therapeutic aspects of acne, and less on perceptions and knowledge of acne patients of their disease. The objective of this study was to evaluate the prevalence, knowledge, beliefs on acne, among pupils and students in Ouagadougou. Patients and Methods:We conducted a cross-sectional study from June to July 2014 in the University of Ouagadougou and in 4 secondary schools in Ouagadougou. Results: We surveyed 425personnes including 40.6% of girls and 59.4% boys. The prevalence of acne was 54.8%. The mean age was 19.53 years, with extremes ranging from 13 to 30 years. Among the etiologies, food was cited by 40.05%, 25.43% puberty, cosmetics 14.03% 3.21% hormones, stress 2.33%, 0.87% seborrhea. Among the foods concerned, peanuts were cited by 37.96%, 21.22% mayonnaise, butter, 21.52%, 8.07% sweets and chocolate 9,41%. oil was incriminated by 72.6% and sugar 5.5%. Among the contributing factors, 19.70% cited tobacco, 19% no sexual relationship. Among the 192 non acne patients, 17% link acne to poor hygiene, 80% would be embarrassed to have a partner acne, 74.40% of non-acne believed that acne altered self-image. For treating acne 26.11% think that acne is incurable. Cosmetic can care acné according to 37,90% and 6,30% believed that natural products are sufficient. Only 15.02% have resorted to a dermatologist. Conclusion: Pupils and students have bad knowledge on acne and bad perception on those who have the disease.

A acne vulgar é uma das dermatoses mais freqüentes na população em geral. Encontra-se na literatura grande número de trabalhos científicos referentes sobretudo a sua etiopatogenia. No entanto, dado o grande número de informações geradas a respeito, dificilmente consegue-se reuni-las em entendimento comum. Esta revisão literária foi proposta a fim de abordar os mecanismos etiopatogênicos clássicos da acne vulgar (produção sebácea, hiperqueratinização folicular, colonização bacteriana folicular e inflamação glandular) e o mecanismo coadjuvante principal, a influência hormonal.
