Abstract
Microneedle radiofrequency (FMR) for the treatment of primary axillary hyperhidrosis radiofrequency (RF) technology is a new modality that applied deep heat energy directly affecting the epidermis and dermis. Limiting data about FMR for axillary hyperhidrosis is concerning. To compare clinical efficacy between fractional microneedle radiofrequency and intradermal botulinum toxin type A injection. This study was a randomized, intraindividual split-side comparative study. Twenty female subjects clinically diagnosed of primary axillary hyperhidrosis were enrolled. All subjects randomly assigned to receive either FMR device on one side of axilla or 50 units of intradermal botulinum toxin A on contralateral side of axilla. Treatment with FMR device was scheduled for 2 sessions for 4 weeks apart. After treatment, mean Hyperhidrosis Disease Severity Score (HDSS) of both groups revealed remarkably better reduction from the baseline (p < 000.1). By comparing between the two groups at the endpoint visit (12th week), the botulinum toxin A group had significantly better reduction of mean HDSS score than the microneedle RF group with 1.60 (0.59) versus 2.05 (0.68), respectively (p = 0.0332). At the week-12 visit, the botulinum toxin A group had significantly better participant's satisfaction score by quartile rating scale than the microneedle RF group (2.55 + 0.69 versus 1.70 + 1.03, respectively, p = 0.004). Therefore, the botulinum toxin A group also demonstrated with significantly better improvement for their quality of life by DLQI score at the 12th week than the microneedle RF group (p = 0.013). Intradermal botulinum toxin A had better efficacy than fractional microneedle radiofrequency for the treatment of primary axillary hyperhidrosis.

Abstract
BACKGROUND: Botulinum neurotoxin (BoNT) effectively downregulates the secretion of eccrine sweat glands in patients with axillary and palmoplantar primary hyperhidrosis (PH).
OBJECTIVE: To demonstrate the efficacy and safety of pressure- and dose-controlled, needle-free, transcutaneous pneumatic injection (TPI) of BoNT-A for treating axillary and palmoplantar PH.
METHODS: Needleless TPI-BoNT-A treatments were delivered on the axillary or palmoplantar skin at a pneumatic pressure of 2.05 bars and an injection volume of 0.08 mL/shot. The efficacy thereof was assessed by evaluating starch-iodine test results and Hyperhidrosis Disease Severity Scale (HDSS) scores.
RESULTS: At baseline, median HDSS scores were 3 (IQR, 3-4) for axillary lesions and 4 (IQR, 3.5-4) for palmoplantar lesions. Median HDSS scores at 1 month after TPI-BoNT-A treatment significantly decreased to 1 (IQR, 1-1.75) for axillary lesions (P < .001) and 1 (IQR, 1-2) for palmoplantar lesions (P < .001). Median global improvement scale scores were 4 (IQR, 3.25-4) for axillary PH and 3 (IQR, 2.5-4) for palmoplantar PH (P > .05). In all patients, pain was tolerable during treatments for both axillary and palmoplantar PH after the application of topical anesthetic cream.
CONCLUSION: Pressure- and dose-controlled, needle-free, BoNT delivery effectively and safely decreased sweating in axillary and palmoplantar skin.

Abstract
BACKGROUND: Axillary hyperhidrosis is a common complaint affecting 5% of the general population. It can significantly impact quality of life (QOL) and may be extremely debilitating. Administration of intra-dermal botulinum toxin type-A (Botox) has been proven to be effective in managing axillary hyperhidrosis; however, to date, no long-term data has assessed its efficacy.
AIM: We aim to assess long-term (> 5 years) QOL outcomes in this patient cohort.
METHODS: In this single-centre series, all patients attending for axillary botox, with five or more years of follow-up, were prospectively included. QOL was assessed in all patients using the validated assessment tool, the modified Dermatology Life Quality Index (DLQI). Standard statistical methods were utilised with data reported as mean (± standard deviation). Subgroup analysis utilising previously published departmental data allowed for further assessment of change in QOL over time.
RESULTS: A total of 75 patients (83% female) met the inclusion criteria with 67% completing the DLQI assessment. Follow-up ranged from 5 to 10 years with a mean age of 37.6 years (± 8.82). The mean number of treatments over the study period was 12 (± 3.1). Mean overall post-treatment DLQI score was 1.6 (± 2.01). This represented a significant improvement in patient QOL (p = < 0.0001) associated with long-term botox application. This statistical significance was identified consistently across all components of the DLQI tool.
CONCLUSION: These data suggest that the established early QOL benefits associated with intra-dermal botox administration for AH are sustained in the long term. This benefit was seen across all subsets of the DLQI tool.

Thoracoscopic sympathotomy for palmar hyperhidrosis: How young is too young?

J Pediatr Surg. 2019 Dec 11;:

Authors: Vasconcelos-Castro S, Soares-Oliveira M, Tuna T, Borges-Dias M

Abstract
BACKGROUND/PURPOSE: Primary hyperhidrosis affects 1%-3% of the general population, with increased incidence in teenagers, having an important impact in the quality of life. This study evaluates the efficacy and patients’ satisfaction after bilateral thoracoscopic sympathotomy.
METHODS: Retrospective analysis of pediatric patients with palmar primary hyperhidrosis that underwent bilateral thoracoscopic sympathotomy over the last eight years. The procedure was performed with 2 ports and simple transection of the sympathetic chain. Pre and postoperative sweating severity was evaluated by telephone interview, using the Hyperhidrosis Disease Severity Scale (HDSS).
RESULTS: 23 patients (19 girls; 15.5 [11-19] years-old) underwent bilateral thoracoscopic sympathotomy. All complained of palmar hyperhidrosis, which resolved in all cases. Compensatory sweating occurred in 47.8% of patients. 21 patients answered the telephone interview: all of them would recommend the surgery to others. Sweating severity improved in all patients, with a mean decrease of 1.95 values of the HDSS from preoperative to postoperative evaluation (p < 0.05). There was neither morbidity nor mortality.
CONCLUSIONS: Bilateral thoracoscopic sympathotomy is a safe and effective treatment for primary palmar hyperhidrosis. Being the first report on pediatric application of HDSS, we conclude that children are very satisfied with the final outcome.
TYPE OF STUDY: Treatment study.
LEVEL OF EVIDENCE: Level III.

The Meaning of Living for Men Suffering From Primary Hyperhidrosis.

Am J Mens Health. 2019 Nov-Dec;13(6):1557988319892725

Authors: Shayesteh A, Brulin C, Nylander E

Abstract
Primary hyperhidrosis means excessive focal sweating and it has a negative effect on the mental health of those affected. Although there is no gender difference regarding the prevalence of the disease, men are less likely to seek help for this condition. The aim of this study was to explore the meaning of living with primary hyperhidrosis in men. Interviews with 15 men, selected by purposive sampling, were performed at Umeå University Hospital in Sweden between June 2016 and October 2017, and analyzed using qualitative content analysis technique according to Graneheim and Lundman (2004). This study found one theme, namely, to be captured in a filthy body, based on the categories: surrender to the condition reluctantly; prepare for a sweat attack; withdraw from close contacts; and worry about others’ perceptions. The theme describes men living with hyperhidrosis feeling filthy while they struggle to control or hide the excessive sweating. Insufficient understanding from others and being reminded from the sweating is stressful and results in a sense of captivity. Interpreting the result, we conclude that the disease could stigmatize the individual, which has a negative effect on mental health and the will to seek help. Meanwhile, providing information about the disease early, as in schools, could increase the willingness of men to seek medical help. The results of this study also reinforce quantitative studies reporting the negative effects of primary hyperhidrosis on mental health.

Botulinum Toxin: Pharmacology and Injectable Administration for the Treatment of Primary Hyperhidrosis.

J Am Acad Dermatol. 2019 Dec 04;:

Authors: Nawrocki S, Cha J

Abstract
Hyperhidrosis is a dermatological condition defined by excessive sweating beyond thermoregulatory needs with significant effects on patients’ quality of life. Hyperhidrosis is categorized as primary or secondary: primary hyperhidrosis is mostly focal and idiopathic, whereas secondary hyperhidrosis is commonly generalized and caused by an underlying medical condition or use of medications. Various surgical and nonsurgical therapies exist for primary hyperhidrosis. Although botulinum toxin is one of the deadliest toxins known, when used in small doses, it is one of the most effective therapies for primary hyperhidrosis. Botulinum toxin injections are widely used as a second-line primary hyperhidrosis treatment option, when topical treatment strategies have failed. This article provides an overview of the commercially available botulinum toxin formulations and their applications for the treatment of primary hyperhidrosis.
