Toxina botulínica em hiperidrose plantar avaliada através de sistema de imagens digitais Botulinum toxin in plantar hyperhidrosis assessed by a digital imaging system

Introduction: Hyperhidrosis is a condition characterized by an excessive and uncontrolled produc- tion of sweat; the most current treatment is botulinum toxin. Objective: Botulinum toxin type A acts through a transient block of acetylcholine release in the cho- linergic autonomic fibers to reduce sweating. Its use is increasing as patients learn about its efficacy. Methods: Patients (n = 7) were treated with botulinum toxin with a total dose of 100 U. We analyzed patient and physician assessments and digital photography images using Image-Pro, a digi- tal imaging system
