7 In a randomized placebo-controlled trial in 3 primary schools in the Netherlands, when duct tape or placebo were administered 1 night a week for 6 weeks, complete resolution of the treated wart was documented in 16% of the children in the duct tape group compared with 6% in the placebo group ( P =. 05), and most warts responded to therapy within a month. In a study conducted in pediatric and adolescent clinics at a military medical centre, 21 of 26 (85%) children in the duct tape group versus 15 of 25 children (60%) in the cryotherapy group had complete resolution of their warts ( P =. The author reported an 80% cure rate after 4 weeks of treatment. Ordinary white adhesive tape was labeled “WART TAPE,” wrapped around a finger for a week, and then removed for 12 hours. In 1978 Litt described treatment of subungual and periungual warts with a safe, easy, simple, painless, inexpensive, and highly effective “trick.” 5 He suggested occlusion of only 1 wart to cure all warts. 2 Some adverse effects include pain, blistering, scarring, skin irritation, skin pigmentation changes, and crust.Ĭimetidine, cantharidin, podophyllin resin, carbon dioxide laser, and heat have also been studied. 3 In the systematic review, 7 studies with almost 750 participants found cryotherapy to have a similar effect to placebo (RR = 1.45 ) for cure of warts, and only after multiple treatments was cryotherapy documented to be more effective (RR = 1.90 ). Immune-mediated processes have also been identified as part of the reason for its mechanism of action. Liquid nitrogen (cryotherapy) spray or application with a cotton ball is aimed at freezing the area, damaging cells and vascular supply. A 2012 systematic review, which included 6 studies with almost 500 participants (children and adults), comparing salicylic acid with placebo showed a modest increase in the chance of clearance of warts with salicylic acid for all sites (risk ratio of 1.56 ), which was higher on the hands (RR = 2.67 ) than on the feet (RR = 1.29 ). There are over-the-counter patches with recommended concentrations of salicylic acid available. ![]() This keratolytic therapy slowly destroys virus-infected epidermis and likely intensifies the local immune response owing to acid irritation. Salicylic acid as a peeling agent is administered on warts for a period of at least 2 to 3 months. ![]() Various therapies have been studied for the treatment of warts. Appliquez un autre morceau de ruban 12 heures plus tard. Pour le traitement avec du ruban adhésif, appliquez un petit morceau de ruban directement sur la verrue une fois tous les 4 à 7 jours ensuite, enlevez le ruban, nettoyez la surface à l’eau et au savon, puis enlevez la peau morte avec une lime-émeri. Les données probantes concernant l’efficacité du ruban adhésif à conduits sont limitées, mais parce que ce traitement est sans danger et bien toléré, les parents peuvent l’essayer à la maison, de même que les timbres d’acide acétylsalicylique. Ces lésions bénignes disparaissent spontanément et aucun traitement n’est recommandé. Réponse Les verrues vulgaires sont très fréquentes chez les enfants et sont causées par le virus du papillome humain. ![]() Le ruban adhésif est-il vraiment efficace pour les verrues vulgaires, et comment faut-il l’appliquer? Même si j’essaie de les convaincre qu’aucune thérapie n’est nécessaire, les enfants et les parents demandent des conseils et des traitements.
