Abstract
JUSTIFICATION: Primary hyperhidrosis is a benign disease that consists in the excessive production of sweat, mainly in the hands, axillas and feet. It may to interfere with the social and work life of the sufferer. It affects up to 3% of the population. In Cuba there are no epidemiological studies on its prevalence. One of the treatment modalities is videothoracoscopic sympathicotomy.
OBJECTIVES: To describe the results of the videothoracoscopic sympathicotomy technique for two ports using apneic oxygenation to achieve lung collapse.
METHOD: Descriptive, retrospective study of 27 cases operated by primary hyperhidrosis in the period from May 2015 to June 2018. Demographic and clinical characteristics of operated patients, results of the endoscopic surgical technique, postoperative complications and satisfaction were described.
RESULTS: The 27 patients were adolescents with ages ranging from 11 to 19 years old, it was more frequent in the female sex. All patients had total solution of the symptoms in the intraoperative period, demonstrated by the cessation of sweat in the palms or axillas and by the verification of the increase of the palmar temperature in the monitor. No patient had intraoperative complications. Compensatory sweating occurred in four patients and one had intercostal neuritis. 100% of the patients were satisfied with the result at 30 days of treatment.
CONCLUSIONS: It is a safe technique, with few complications, high satisfaction with the results and feasible to perform in pediatric hospitals with basic resources of minimal access surgery.

Abstract
Changes in the duration of efficacy of botulinum toxin A injections for primary axillary hyperhidrosis have not been studied in depth. The aim of this study was to assess such changes. In a retrospective cohort of 220 patients, seen over a 17-year period, duration of efficacy was recorded, including duration of efficacy of first and last injections. Of 220 patients, 117 fulfilled the study criteria (79 females and 38 males, age 17-79 years, mean age 38.3 years). Patients received 3-24 injections (mean 5.5). The duration of efficacy of the first injections was 3 weeks to 30 months (median 6 months), and the duration of efficacy of the final injections was 3 weeks to 66 months (median 8 months) (p < 0.001). An increase in duration of efficacy occurred in 62% of patients. Of the 20 patients with a follow up ≥10 years, the mean number of treatments was 8.25/patient; in 18 of these patients the duration of efficacy increased by > 50%. In conclusion, repeated botulinum toxin A injections lead to an increase in duration of efficacy without secondary decrease.

Abstract
primary hyperhidrosis (HH), a dysregulation of the parasympathetic nerve system, is characterized by focal symmetrical sweating of axillae, palms or the plantar region.1 Hyperhidrosis is a chronic condition with severe impact on patients’ quality of life, however, more than 50% of hyperhidrosis patients receive no treatment.1,2 Overall prevalence was reported to be 16% in German adults, with axillary hyperhidrosis being the most common form of HH.2 The objective of this study was to assess safety and tolerability, efficacy and pharmacokinetics, of escalating concentrations of glycopyrronium bromide (GPB), a competitive antagonist of muscarinic acetylcholine receptor mAChR, in subjects with axillary hyperhidrosis.

Abstract
BACKGROUND: Glycopyrronium tosylate is a topical anticholinergic approved in the USA for primary axillary hyperhidrosis in patients aged ≥ 9 years (Qbrexza™ [glycopyrronium] cloth, 2.4%).
OBJECTIVE: This 44-week open-label extension study assessed glycopyrronium tosylate safety and descriptive efficacy in patients completing one of two, phase III, double-blind, vehicle-controlled, 4-week trials (NCT02530281; NCT02530294).
METHODS: Patients aged ≥ 9 years with primary axillary hyperhidrosis were randomized 2:1 (glycopyrronium tosylate: vehicle, once daily) in the double-blind trials. Completers could receive open-label glycopyrronium tosylate for up to an additional 44 weeks. Treatment-emergent adverse events and local skin reactions were assessed. Descriptive efficacy assessments were gravimetrically measured sweat production, Hyperhidrosis Disease Severity Scale responder rate (≥ 2 grade improvement), and Dermatology Life Quality Index/children’s Dermatology Life Quality Index.
RESULTS: Of 651 patients completing the double-blind trials, 564 (86.6%) entered the open-label extension; 550 were analyzed. Most patients experiencing treatment-emergent adverse events had mild or moderate events (> 90%). Discontinuation because of treatment-emergent adverse events remained low and relatively stable, with a cumulative rate of 8.0% (44/550) over 44 weeks. Common treatment-emergent adverse events (> 5%) were dry mouth (16.9%), vision blurred (6.7%), application-site pain (6.4%), nasopharyngitis (5.8%), and mydriasis (5.3%). Most patients (67.5%) had no local skin reactions; those occurring were predominantly mild/moderate. Glycopyrronium tosylate efficacy was maintained throughout the trial; at week 44, the Hyperhidrosis Disease Severity Scale responder rate was 63.2%, and improvements from baseline (double blind) in sweat production were - 71.3% and 8.7 ± 6.2/6.2 ± 4.9 for Dermatology Life Quality Index/children’s Dermatology Life Quality Index.
CONCLUSIONS: Daily long-term application of glycopyrronium tosylate for up to 48 weeks (double blind plus open label) was generally well tolerated and efficacy was maintained. No new safety signals emerged.

Glycopyrronium Tosylate (Qbrexza) for Hyperhidrosis

Skin Therapy Lett. 2019 Mar;24(2):1-3

Abstract
Hyperhidrosis is a condition characterized by excessive sweat production beyond which is physiologically necessary for thermal regulation. Affecting over 4.8% of the United States population, studies have shown that severe primary hyperhidrosis interferes with daily activities and can be considered intolerable, negatively impacting a patient’s quality of life. Glycopyrronium tosylate is a topical anticholinergic agent that reduces sweat production by blocking the activation of acetylcholine receptors in peripheral sweat glands. In clinical trials, topical glycopyrronium tosylate, a pre-moistened cloth containing 2.4% glycopyrronium solution, was shown to be an effective, safe and non-invasive treatment for patients suffering from primary hyperhidrosis. This review examines the clinical trials of topical glycopyrronium tosylate and its role in primary hyperhidrosis. Glycopyrronium tosylate was recently US FDA-approved (as of June 2018) to manage patients with primary axillary hyperhidrosis.

Abstract
BACKGROUND AND OBJECTIVES: Microwave treatment is an effective non-invasive treatment option for primary axillary hyperhidrosis (PAH), but the treatment parameters vary and no histopathological studies have been performed to validate clinical outcomes. This study investigated its efficacy and safety and histopathological changes after a single microwave treatment at the maximum energy level for PAH in Asians.
MATERIALS AND METHODS: A prospective, clinical, and histological split-area randomized controlled trial (RCT) was performed in Japan. Twenty-six subjects underwent a single microwave treatment at the maximum energy level 5 (5.8 GHz/axilla) on the randomized side of axillae. The primary outcome was the mean difference between both sides in the improvement of modified single-underarm Hyperhidrosis Disease Severity Scale (msHDSS) scores over the course of the 12-month study period from baseline. The secondary outcomes were; the percentage of responders with at least a 2-point drop in the msHDSS score of 3 or 4 group or with a 1-point drop in the msHDSS score of 2 group; the percentage of responders with at least a 75% reduction in sweat weight over 12 months; recurrence rate; and adverse effects. We also performed a histological assessment for 13 selected subjects.
RESULTS: Twenty-four subjects completed the study. There were statistically significant differences in improvement of msHDSS scores between the microwave-treated and control sides (P < 0.05) from baseline at 0.5, 1, 3, 6, and 12 months. In the msHDSS score of 3 or 4 group, the percentage of responders with at least a 2-point drop on the microwave-treated side versus control side was 72.2 versus 11.1% (P < 0.05) at 1 month, 83.3 versus 5.6% (P < 0.05) at 3 months, 61.1 versus 38.9% (P = 0.317) at 6 months and 38.9 versus 16.7% (P = 0.264) at 12 months. The percentage of responders with at least a 75% reduction in sweat weight on the microwave-treated side versus control side was 75.0 versus 37.5% at 1 month, 75.0 versus 29.2% at 3 months, 83.3 versus 50.0% at 6 months and 70.8 versus 33.3% at 12 months (all P < 0.05). Recurrence on the microwave-treated side was observed in 4.2% and 12.5% of 24 subjects at 3 and 12 months, respectively. No serious side-effects were noted. Histology showed the diameter and density of secretory eccrine glands and nerve fiber lengths around eccrine glands were significantly decreased after treatment compared to baseline (P = 0.002, 0.027, 0.003, respectively).
CONCLUSIONS: A single-session microwave treatment at the maximum energy level significantly improved the PAH of Japanese patients and had minimal side effects. This technique demonstrates that diminished size of secretory eccrine glands and nerve fiber degeneration could be useful markers for predicting the efficacy of the treatment. Lasers Surg.

The Etiology, Diagnosis and Management of Hyperhidrosis: A Comprehensive Review. Part II. Therapeutic Options.

J Am Acad Dermatol. 2019 Jan 30;:

Abstract
Hyperhidrosis (HH) is a chronic disorder of excess sweat production that may have a significant adverse effect on quality of life. A variety of treatment modalities currently exist to manage HH. Initial treatment includes lifestyle and behavioral recommendations. Antiperspirants are regarded as the first-line therapy for primary focal HH and can provide significant benefit. Iontophoresis is considered to be the primary remedy for palmar and plantar HH. Botulinum toxin (BTX) injections are administered at the dermal-subcutaneous junction and serve as a safe and effective treatment option for focal HH. Oral systemic agents are reserved for treatment-resistant cases or for generalized HH. Energy delivering devices such as lasers, ultrasound technology, microwave thermolysis, and fractional microneedle radiofrequency may also be utilized to reduce focal sweating. Surgery may be considered when more conservative treatments have failed. Local surgical techniques, particularly for axillary HH, include excision, curettage, liposuction, or a combination of these techniques. Sympathectomy is the treatment of last resort when conservative treatments are unsuccessful or intolerable, and after accepting secondary compensatory HH as a potential complication. A review of treatment modalities for HH and a sequenced approach are presented.

Bilateral brachial plexus injury after MiraDry® procedure for axillary hyperhidrosis: a case report.

World Neurosurg. 2019 Jan 28;:

Abstract
Multiple treatments are available for primary axillary hyperhidrosis, including non-invasive, microwave based thermal treatments designed to destroy sweat glands in the axilla. Often these procedures involve local anesthetic injection to the axilla, followed by placement of the microwave emitter onto the skin and applying the heat treatment to varying depths of the subcutaneous tissues. CASE REPORT: A 49-year old, thin and active woman (BMI 19.6) underwent microwave based treatment to the bilateral axillary regions. She experienced an electric sensation into the ulnar digits of the right hand during anesthetic injection, and then underwent the microwave thermal treatment. She suffered a bilateral brachial plexus injury with imaging evidence of severe, subcutaneous edema surrounding the nerves of the plexus in the axilla, as well as denervation atrophy of the arm and forearm muscles bilaterally. At the time of evaluation and EMG, 8 months after treatment, she had recovered significant strength in the left upper extremity, but continued to have evidence of a severe radial nerve injury on the right. EMG demonstrated some recovery and observation was recommended followed by secondary reconstruction if required. It is likely that the patient sustained thermal injury to the nerves in the axilla bilaterally, given the close proximity to the skin surface in a patient with a low BMI. CONCLUSION: In thin patients undergoing treatment of primary axillary hyperhidrosis, consideration should be given to the distal brachial plexus which may be at risk of damage with high powered microwave-based therapy.

Abstract
Background: Hyperhidrosis is a functional disorder identified by excessive sweating. Its incidence is approximately 1% in any population. Bilateral endoscopic thoracic sympathectomy (BETS) intervention is the definitive treatment of choice for palmar and axillary hyperhidrosis.
Aims and Objectives: The purpose of this study is to evaluate and compare the quality of life (QOL) and satisfaction rate of patients with upper limb hyperhidrosis before and after BETS surgery and the influence of compensatory hyperhidrosis (CH) on patients’ QOL after surgery.
Settings and Design: This study is a cross-sectional study designed to generate longitudinal data.
Subjects and Methods: This study is a cross-sectional study designed to generate longitudinal data pre- and postbilateral BETS prospectively. This study was conducted in the surgery department of University Hospital in Riyadh, Saudi Arabia. Hundred patients with upper limb hyperhidrosis who underwent BETS from 2014 to 2017 were included. A modified and validated QOL questionnaire for hyperhidrosis was completed by the patients themselves in order to compare the QOL for patients both before and after BETS. Patients’ satisfaction and the occurrence of CH were obtained postoperatively.
Statistical Analysis Used: Data were analyzed using the SPSS® statistical package for social studies, version 22.0 (SPSS 22; IBM Corp., New York, NY, USA) for Windows®.
Results: A total of 100 patients completed the questionnaire; 94% of patients had a positive QOL outcome after the surgery. The mean decrease in QOL scores was -42.0 points toward better QOL. The site of sweating had a significant effect on the patients’ QOL before and after the surgery (P value < 0.001). Moreover, 76% of patients reported a high satisfaction rate.
Conclusion: Primary hyperhidrosis can negatively impair patients’ QOL in different domains. BETS showed to be an effective option for improving the QOL of patients and it provided both short- and long-term effectiveness in treating upper limb hyperhidrosis. CH did not interfere with the rate of patient satisfaction or their QOL postoperatively.
