Botulinum toxin: An effective treatment for prosthesis-related hyperhidrosis in patients with traumatic amputations

Percutaneous treatments for residual and/or phantom limb pain in adults with lower-extremity amputations: A narrative review

Residual limb pain (RLP) and phantom limb pain (PLP) profoundly affect the lives of many individuals who have undergone lower- or upper-extremity amputation. Despite the considerable impact of RLP/PLP on quality of life in persons with amputation, there have been few attempts to evaluate the efficacy of percutaneous interventions in the treatment of RLP and/or PLP. This narrative review evaluates the effectiveness of percutaneous treatments for RLP and/or PLP in patients after lower-extremity amputation. Peripheral nerve stimulation, alcohol neurolysis, conventional thermal radiofrequency ablation, perineural corticosteroid injection, botulinum toxin injection, and etanercept injection were associated with varying success rates. Wide confidence intervals and small treatment cohorts impede assessments of overall success. High-quality studies of nonsurgical, percutaneous treatments for RLP and/or PLP are lacking. Well-designed randomized controlled trials and large cohort studies with comparison groups using validated outcomes are needed to determine the effectiveness of nonsurgical interventions for the treatment of RLP and PLP.

Hyperhidrosis of the residual limb: a narrative review of the measurement and treatment of excess perspiration affecting individuals with amputation

BACKGROUND

Hyperhidrosis (HH) is a relatively common disorder involving excessive sweating, typically of the palms or axilla. HH can also frequently occur after limb amputation, where the remaining residual limb excessively perspires, leading to an increased risk of dermatological disorders and functional limitations, such as the inability to comfortably or safely wear a prosthesis. Although many treatments have been proposed to treat HH within the dermatology community, they are not widely known by healthcare providers typically involved in caring for individuals with acquired limb loss.

OBJECTIVES

To appraise the current state of quantitative and qualitative assessment of HH within the residual limb and examine existing and future treatment strategies for this problem.

STUDY DESIGN

Narrative Literature Review.

METHODS

A literature review focused on the assessment and treatment of excessive sweating of residual limbs.

RESULTS

There is currently no objective or subjective standard to assess or diagnose HH of the residual limb. Conventional therapies for HH do not always translate to the population of individuals with limb loss. Emerging modalities for treating HH show promise toward a permanent resolution of excess perspiration but require additional studies within people with amputation.

CONCLUSIONS

Further research is needed to quantify standard values to objectively and subjectively assess and diagnose hyperhidrosis of the residual limb. New and developing treatments for hyperhidrosis require additional studies to assess efficacy and safety in the residual limb.

New trends in botulinum toxin use in dermatology

Background: Recent studies have highlighted new botulinum neurotoxin (BoNT) applications in the field of dermatology. Objective: To review current knowledge of BoNT use in dermatology. Methods: The literature of the last 5 years has been reviewed. Results: We describe interesting protocols of BoNT treatment for hyperhidrosis (HH), hypertrophic scars and keloids, Raynaud phenomenon, facial flushing, oily skin, psoriasis, Hailey-Hailey disease, and cutaneous lesions like painful lesions and periorbital syringomas. Conclusions: Several skin conditions eligible for BoNT treatment have been described. After the wide application for HH treatment, scars as well as vascular and inflammatory skin disorders, oily skin and cutaneous lesions represent fields of application of BoNT.
