title: Residual Limb Hyperhidrosis Managed by Botulinum Toxin Injections, Enhanced by the Iodine-Starch Test: A Case Report.
abstract: Hyperhidrosis of the residual limb is a common condition affecting patients with amputations. The iodine-starch test is used by dermatologists to identify focal areas of hyperhidrosis before treatment with botulinum toxin. Here, we describe a case of a patient with a transtibial amputation with moderate-to-severe hyperhidrosis who received intradermal botulinum toxin injections to treat residual limb hyperhidrosis, with particular emphasis given to the utility of the iodine-starch test in managing this common condition. The iodine-starch test successfully identified hyperhidrotic areas before treatment as well as confirmed the physiologic anhidrotic effect of the botulinum toxin treatment.
