    Introduction and objectives: Androgenetic alopecia in men (AGA) and female pattern hair loss (FPHL) are common hair loss causes which may heavily influence self-esteem and self-image. AGA and FPHL are caused by the heightened sensitivity of scalp follicles to dihydro-testosterone leading to dysregulation of downstream signaling cascades of inflammation. As a consequence a process of hair miniaturization develops over the time usually paralleled with a characteristic pattern distribution that varies between men and women. Histological observations showed perifollicular cells infiltrates and micro-inflammation. As this is a chronic condition, efficacy of products but also tolerability, cosmetic acceptance and patient satisfaction are key to ensure a good compliance. The aim of this study was to assess the benefit and tolerability of Aminexil clinical 5 (AC5, containing Aminexil, Arginine, SP94, piroctone olamine and Vichy mineralizing water as active ingredients) in subjects with mild alopecia. Materials and methods: This was an open-label, observational, international study conducted in real life settings in 527 adult female and male subjects with mild alopecia. At baseline subjects underwent a clinical examination including Ludwig for female and Hamilton Norwood scoring for male subjects and received AC5 to be applied once daily for a minimum of 45 days. At the end of treatment, subjects assessed their hair growth and quality, satisfaction and local tolerance; investigators evaluated the impact of AC5 on the subjects’ hair. Results: Data from 421 subjects were evaluable for the efficacy analysis. Tolerability data were available for 509 subjects. 58.7% of subjects were females; the mean age was 34.1±9.1 years. Duration of hair loss was 1.3±1.8 years in women and 2.3±2.6 years, overall mean duration was 1.7±2.2 years. AC5 was used in combination with prescription treatments in 14.8% of cases (mainly topical) at inclusion with non-medical products (topicals and/or orals) in 42.2% of cases; 71.3% of women had a Ludwig score of 1 and 40.8% of males had a Hamilton Norwood score of 2. After a mean of 82.9±17.5 days of use dermatologist evaluation rated an improvement in hair loss in 87.1% of subjects compared to baseline; it was somewhat better in women (91.8%) than in men (80.3%). Subject satisfaction on a scale from 0 (not satisfied at all) to 10 (completely satisfied) was 7.9±1.7. Tolerance was good to very good in 98.6% of subjects. The texture was considered pleasant by 95% of subjects. Conclusion: In subjects with mild alopecia, AC5 reduces hair loss in both men and women with a pleasant texture. AC5 was well tolerated and highly appreciated by subjects and investigators

    Mutation and Abnormal Expression of the p53 Gene in the Viral Skin Carcinogenesis of Epidermodysplasia Verruciformis

    International audiencePatients suffering from epidermodysplasia verruciformis are prone to nonmelanoma skin cancers, due to an inherited abnormal susceptibility to the oncogenic human papillomavirus type 5. Genotoxic sunlight ultraviolet B radiations are likely to be a cofactor. Lesions of two human-papillomavirus-type-5-infected epidermodysplasia verruciformis patients collected during an 8 y period were retrospectively studied for p53 mutations in exons 5 through 8 by a polymerase chain reaction single-strand conformation polymorphism technique and/or by DNA sequencing of amplified exons. Mutations were detected in 11 of 26 (42.3%) specimens, including five (62.5%) squamous cell carcinomas, three (33.3%) Bowen's carcinomas in situ, two (40%) actinic keratoses, and one (33%) benign lesion. The nine mutations characterized by sequencing were shown to be missense and to affect mutational hotspots in human cancers. Five were C-->T transitions at dicytidine sites considered as ultraviolet signature mutations. Two were transversions (C-->G and C-->A) at dicytidine sites and two were C-->T transitions at nondipyrimidine sites. A marked p53 immunoreactivity was disclosed in 72.7% of 11 invasive carcinomas, 55.6% of nine carcinomas in situ, 37.5% of eight actinic keratoses, and one of three benign lesions. This includes 81.8% of 11 specimens with a p53 mutation but also 50% of 14 specimens with no mutation detected. A dysfunction of the p53 gene is thus likely to play a part in epidermodysplasia verruciformis carcinogenesis, either due to ultraviolet-B-induced p53 mutations, as in nonmelanoma skin cancers in the general population, or involving other mutagens or mechanisms. The part played by human papillomavirus type 5 proteins expressed in epidermodysplasia verruciformis keratinocytes remains to be determined

    EfficacitĂ© d’aminexil clinical 5 chez des sujets avec une alopĂ©cie lĂ©gĂšre: rĂ©sultats d’une large Ă©tude internationale observationnelle

    Introduction: L’alopĂ©cie androgĂ©nique (AAG) est une cause frĂ©quente de la chute chronique de cheveux, un phĂ©nomĂšne qui peut impacter l’estime de soi et l’image des sujets. Pour cela, il est important de connaitre l’efficacitĂ© des produits, mais aussi leur tolĂ©rance, leur acceptation cosmĂ©tique et la satisfaction de l’utilisateur afin d’assurer un bonne observance thĂ©rapeutique. Cette Ă©tude Ă©valuait le bĂ©nĂ©fice et la tolĂ©rance de l’aminexil clinical 5 (AC5), contenant de l’aminexil, de l’arginine, du SP94, de la piroctone olamine, et de l’eau volcanique minĂ©ralisante de Vichy, chez des sujets ayant une alopĂ©cie lĂ©gĂšre. MatĂ©riels et mĂ©thodes: Cette Ă©tude observationnelle internationale a Ă©tĂ© menĂ©e dans des conditions rĂ©elles chez 527 adultes avec une alopĂ©cie lĂ©gĂšre. En dĂ©but d’étude (J0), les sujets Ă©taient Ă©valuĂ©s cliniquement Ă  l’aide de l’échelle de Ludwig pour les femmes et de l’échelle Hamilton-Norwood pour les hommes. Les sujets recevaient ensuite de l’AC5 Ă  appliquer une fois par jour sur le cuir chevelu pendant au moins 45 jours. A la fin du traitement, les sujets Ă©valuaient la poussĂ©e et la qualitĂ© de leurs cheveux ainsi que leur satisfaction et la tolĂ©rance locale. Les investigateurs Ă©valuaient l’efficacitĂ© de l’AC5 sur l’alopĂ©cie. Observations: Les donnĂ©es de 421 sujets Ă©taient disponibles pour analyser l’efficacitĂ©, et celles de 509 sujets pour Ă©valuer la tolĂ©rance. En tout, 58,7% des sujets Ă©taient des femmes, et l’ñge moyen Ă©tait de 34,1±9,1 ans. La durĂ©e de la perte de cheveux Ă©tait de 1,3±1,8 annĂ©es chez les femmes et de 2,3±2,6 annĂ©es chez les hommes, avec une durĂ©e moyenne globale de 1,7±2,2 annĂ©es. A l’inclusion, 14,8% des sujets ont reçu de l’AC5 en parallĂšle avec des traitements prescrits (majoritairement topiques), et 42,2 % des sujets avec des produits en vente libre (topiques et/ou oraux) ; 71,3% des femmes avaient un score de Ludwig de 1, et 40,8% des hommes avaient un score Hamilton Norwood de 2. RĂ©sultats: AprĂšs une durĂ©e d’utilisation moyenne de 82,9±17,5 jours, les dermatologues ont notĂ© une amĂ©lioration de la perte de cheveux chez 87,1% des sujets comparĂ© au J0. L’amĂ©lioration Ă©tait lĂ©gĂšrement meilleure chez les femmes (91,8%) que chez les hommes (80,3%). Le score moyen de satisfaction du sujet, sur une Ă©chelle de 0 (pas du tout satisfait) Ă  10 (complĂštement satisfait), Ă©tait de 7,9±1,7. La tolĂ©rance Ă©tait bonne ou trĂšs bonne chez 98,6% des sujets, et 95% des sujets considĂ©raient la texture de l’AC5 agrĂ©able. Discussion: Chez des sujets avec une AAG lĂ©gĂšre, l’AC5 est efficace en condition de vie rĂ©elle aussi bien chez les femmes que chez les hommes, avec une texture considĂ©rĂ©e comme agrĂ©able. L’AC5 a Ă©tĂ© trĂšs bien tolĂ©rĂ© et trĂšs apprĂ©ciĂ© par les sujets
