Abstract
Hyperhidrosis is a disorder that produces excess amount of sweat. The botulinum neurotoxin A (BoNT/A) has been used to treat hyperhidrosis through multiple intradermal injections at the site of condition. However, due to its toxicity, it is important to precisely deliver the proper dose of toxin to the target site. In addition, the use of conventional hyperdermic needle for multiple injections in the palm makes the approach undesirable and painful. Here, we designed a BoNT/A-coated microneedle (BoNT-MN) array and tested its efficacy as a substitute pain-free method to treat hyperhidrosis. BoNT-MNs were prepared by coating BoNT/A formulation on poly-lactic acid microneedles and were found to successfully penetrate in vitro thick skin. The coating formulations were then tested for its stability at 4°C, 25°C, and 37°C for 24 h. BoNT-MNs were found to be much more stable than its liquid state. Additionally, we carried out in vivo experiments by treating the right paw of mice with BoNT-MNs and found that the treatment induced a significant reduction of sweating response in the mouse’s foot pads. Thus, BoNT/A treatment with microneedles is beneficial and may be used as a more efficient and less painful approach to treat hyperhidrosis.

Topical Glycopyrronium Tosylate in Primary Axillary Hyperhidrosis: A Profile of Its Use.

Topical Glycopyrronium Tosylate in Primary Axillary Hyperhidrosis: A Profile of Its Use.

Clin Drug Investig. 2019 Sep 30;:

Authors: Lamb YN

Abstract
Glycopyrronium tosylate (Qbrexza™) is available as single-use, pre-moistened cloths and has been approved in the USA for the topical treatment of primary axillary hyperhidrosis in adults and children ≥ 9 years of age. Glycopyrronium tosylate is effective in reducing patient-reported severity of disease and gravimetrically measured sweat production in this patient population; improvements have been shown to be maintained throughout long-term treatment (up to 48 weeks). Glycopyrronium tosylate is generally well tolerated, with most adverse events being mild to moderate in severity. Glycopyrronium tosylate thus provides a self-administered, non-invasive alternative to topical antiperspirant therapy and clinic-based treatments in adults with primary axillary hyperhidrosis, and is the only alternative to topical antiperspirants specifically approved in children and adolescents ≥ 9 years of age.

Radiofrequency in the treatment of primary hyperhidrosis: systematic review and meta-analysis.

Clin Auton Res. 2019 Sep 24;:

Abstract
PURPOSE: To evaluate, via a systematic review, the effectiveness of radiofrequency (RF) for treatment of primary hyperhidrosis (PH).
METHODS: Experimental or observational studies were included where RF treatment (ablation or microneedling) was performed, comparing the periods before and after treatment.
RESULTS: Nine studies were considered eligible and included for analysis. In seven of nine studies, patients were subjected to RF only, and in two of nine studies RF was compared to video-assisted thoracoscopic sympathectomy (VATS). There was a reduction in the severity of PH in microneedling (three studies, mean difference -1.24, 95% CI -1.44 to -1.03). In a study that performed sympathetic RF ablation there was a greater reduction in PH severity compared to studies that performed microneedling (-2.42, 95% CI -2.55 to -2.29). There was improvement in the quality of life (QoL) after sympathetic RF ablation (two studies, mean difference -15.92, 95% CI -17.61 to -14.24). Regarding the microneedling procedure, there was a lower improvement in QoL, (two studies, -9.0, 95% CI -9.15 to -8.85). One study comparing sympathetic RF ablation with VATS applied the QoL questionnaire, and the VATS showed superior results. One of the two studies comparing compensatory sweating in RF ablation with VATS showed that compensatory hyperhidrosis was higher in VATS; however, the other study did not observe this difference. One study compared the recurrence of symptoms between VATS and RF ablation; symptom recurrence was shown to be higher in RF.
CONCLUSIONS: RF is effective for PH treatment, with superior results obtained with sympathetic ablation compared to microneedling.

Abstract
BACKGROUND: The discussions at the surgical levels (sympathectomy levels) about endoscopic thoracic sympathectomy (ETS) method, which is applied in hyperhidrosis treatment in the present day and acknowledged as the golden treatment method, continue. Mainly, most of the studies evaluates postoperative early period results. Our aim in this study is to compare the long-term quality of life depending on the different surgical levels (sympathectomy levels) and evaluate the postoperative complications.
METHODS: 165 patients operated due to palmar hyperhidrosis between January 2012 and July 2017 were evaluated. Sympathectomy was performed either by clipping or cauterization and sympathetic nerves included were T2-4, T3-4, or T3 levels. Data were retrospectively reviewed for complications, factors affecting the postoperative quality of life.
RESULTS: Ninety of the patients were male (54.5%) and 75 (45.5%) were female. The level of ganglion block was T2-T4 in 62 patients (37.6%), T3-T4 in 46 patients (27.9%), and T3 in 57 patients (34.5%). Early complications were observed in 27 patients (16.4%). Compensatory hyperhidrosis (CH) was observed in 62 patients (37.6%). There was a significant difference in the postoperative quality of life according to ETS level (p < 0.001). Patients who underwent T2-T4 sympathectomy had a lower quality of life than patients who underwent isolated T3 or T3-T4 sympathectomy.
CONCLUSION: Based on our results, we recommend performing lower level resections to increase the long-term quality of life in palmar hyperhidrosis patients. The lower risk of CH and comparable quality of life suggest that T3 sympathectomy is more effective.

Abstract
OBJECTIVE: Several factors that could influence the efficacy and satisfaction of patients after bilateral thoracic sympathectomy (VATS) in the treatment of hyperhidrosis (HH) have been studied, but no studies in the literature have specifically analyzed the effectiveness of treatment and variations in the quality of life of patients aged 40 years or older compared to those of young adult patients (19-40 years).
METHODS: We retrospectively analyzed 2431 hyperhidrosis patients who underwent bilateral VATS and divided the patients into the following groups: a group <40 years old (1760 patients) and a group ≥40 years (142 patients). Variables included quality of life prior to surgery, improvement in quality of life after surgery, clinical improvement in sweating, presence of severe compensatory hyperhidrosis and general satisfaction at one month after surgery.
RESULTS: We observed that all surgical patients presented with poor or very poor quality of life before surgery, with similar proportions in both groups. In the postoperative period, we observed improvement in quality of life in more than 90% of the patients, with no significant difference noted between the two groups of patients. More than 90% of the patients in this series had great clinical improvement in the main hyperhidrosis site, with no significant difference between the two groups. Severe compensatory hyperhidrosis occurred in 23.8% of the patients in this series, with no significant difference between the two groups.
CONCLUSIONS: Patients 40 years of age or older benefit just as much as younger patients from VATS performed to treat primary hyperhidrosis, presenting excellent, significant surgical results.

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
Hyperhidrosis can seriously impair patients’ quality of life. Medical history, including heredity and hyperhidrosis during youth, as well as current age and time elapsed since menopause, is important to consider when distinguishing between postmenopausal hyperhidrosis and vasomotor symptoms to enable adequate treatment. This report concerns a subgroup of eight postmenopausal patients participating in a randomized controlled trial regarding botulinum toxin (Btx) type B treatment in craniofacial hyperhidrosis. Even though the sample size is small and the enrolment is not yet completed, the promising data collected hitherto are interesting to present in advance because this subtype of craniofacial hyperhidrosis is often underrecognized and challenging to treat. Patients were randomized to receive Btx type B or placebo. Measurements were performed before treatment and 3 ± 1 weeks after. The Dermatology Life Quality Index (DLQI) score was improved for all patients after Btx type B treatment (n = 3) with a median decrease of 9 points (90% median improvement). The placebo group (n = 5) had a median increase of 2 points (-18% median decline). When the same group (n = 5) received Btx type B (open) the DLQI score decreased with a median of 7 points compared with baseline (91% median improvement). Treatment-related adverse events were temporary and did not prevent improvement of life quality. Furthermore, background data evaluation uncovered interesting findings regarding vasomotor symptoms in relation to postmenopausal hyperhidrosis. In conclusion, the results indicated that Btx type B seems to be a safe and effective treatment in postmenopausal craniofacial hyperhidrosis. Further research is encouraged.

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.
