The pathogenesis of palmoplantar hyperhidrosis (HH) remains unknown. A causative therapy is therefore not possible yet. Step by step treatment for palmoplantar HH is advised. This includes: topical aluminium salts, tap water iontophoresis (TWI), botulinum toxin (BTX) injections and endoscopic thoracoscopic sympathectomy (ETS). The mechanism of action of TWI(More)
