Abstract
BACKGROUND: Palmar hyperhidrosis represents a condition with a significant cosmetic and psychological burden. Various treatment modalities are available; however, searching for newer options to meet patients’ needs and expectations is encouraged.
AIM: The study aimed to evaluate the efficacy of photodynamic therapy (PDT) for treatment of primary palmar hyperhidrosis. Two different photosensitizers for PDT were evaluated: eosin Y, and methylene blue. The study focused on the clinical efficacy, patient’s satisfaction, and the time & number of sessions needed to achieve a satisfactory response.
METHODS: Twenty patients with primary palmar hyperhidrosis were enrolled in a single-center clinical study. Patients were treated with PDT for a maximum of eight sessions. Two photosensitizers were tested: eosin Y, and methylene blue for the right and left hand, respectively. The Hyperhidrosis disease severity scale (HDSS), and Sweating Intensity Visual Scale of Minor’s test were used for assessment.
RESULTS: Photodynamic therapy effectively reduced the severity scores of hyperhidrosis with comparable results between the two photosensitizers. The treatment effect was maintained up to three months after the last procedure.
CONCLUSION: Photodynamic therapy is a good treatment option for primary palmar hyperhidrosis with results maintainable for three months after the treatment end.

Abstract
The term craniofacial hyperhidrosis (HH) refers to HH that affects the face and/or scalp. Few studies have focused on this specific location, and even fewer distinguish between the two areas. Our study aims are to describe the clinical characteristics of patients with craniofacial HH, specifying whether the condition affects the scalp, face or both, and to compare these cases with those recorded at other locations. As secondary objectives, we determine the effectiveness and adverse effects of oral oxybutynin (OOx), and assess patients’ adherence to treatment. This prospective observational study was carried out with respect to the period 2007-2019. All patients diagnosed with HH of the scalp and/or face and who were treated with OOx at our HH unit were included in the study group. Of 292 patients treated with OOx, 97 (33.2%) had craniofacial HH. Of these, four (4.1%) presented HH exclusively on the scalp, 56 (57.7%) exclusively on the face and 37 (38.1%) in both locations. The patients in the latter category (compared to those with exclusively facial HH) were significantly older than the others, had a later onset of HH, a greater frequency of secondary HH, less simultaneous involvement of the classical areas of primary focal HH (the palms, soles and armpits) and greater generalised HH and of the trunk. No significant differences were observed between the three locations (face, scalp or both) regarding the efficacy and side effects of OOx. The patients with exclusively facial HH presented greater adherence to treatment. This article is protected by copyright. All rights reserved.

Cost-effectiveness of topical glycopyrronium tosylate for the treatment of primary axillary hyperhidrosis.

J Med Econ. 2020 Dec 01;:1

Authors: Bloudek LM, Gillard KK, Nguyen VB, Klein SZ

Abstract
AIMS: Primary axillary hyperhidrosis (PAHH) is a condition characterized by excessive sweating that negatively impacts health-related quality of life, with significant psychological and social impacts. Glycopyrronium tosylate (GT) is a topical anticholinergic approved in the United States for treatment of PAHH in patients 9 years of age and older. Our objective was to assess the cost-effectiveness of GT as first-line topical therapy compared to topical aluminum chloride from a United States commercial perspective.
MATERIALS AND METHODS: A Markov model was developed consisting of four health states based on the Hyperhidrosis Disease Severity Scale (HDSS) over a time horizon of five years with discount rates of 3% for both costs and outcomes. Transitions between health states were driven by HDSS response, defined as an improvement of ≥2 points. Non-responders and those who discontinue could switch to later line treatments or no treatment. Health utility scores were based on HDSS scores, supported by published literature.
RESULTS: Over five years, GT yielded 0.12 greater QALYs and 0.93 greater LYs with response compared to treatment with prescription aluminum chloride at an incremental cost of $10,584. Relative to prescription aluminum chloride, GT resulted in an incremental cost-effectiveness ratio (ICER) of $87,238 per QALY gained, $11,349 per LY with response. The ICER fell below $100,000 for 66% of probabilistic sensitivity analysis simulations and below $150,000 for 82% of simulations.
LIMITATIONS: This analysis represents a simplified scenario of a hypothetical PAHH patient. Due to sparse data, assumptions were required for treatment patterns, efficacy, and persistence.
CONCLUSION: Based on the analysis of incremental cost per QALY gained, GT is may be cost-effective relative to prescription aluminum chloride at commonly accepted willingness to pay thresholds.

Differences in subjective and objective evaluation of hyperhidrosis. Study among medical students.

Postepy Dermatol Alergol. 2020 Oct;37(5):700-704

Authors: Dobosz Ł, Stefaniak T, Halman J, Piekarska A

Abstract
Introduction: Hyperhidrosis is a condition that significantly impairs patients’ quality of life. Qualification for treatment in most cases is based only on subjective evaluation of symptoms without objective confirmation.
Aim: To evaluate the differences between subjective and objective evaluation of sweating among medical students.
Material and methods: There were 179 participants involved in the study. Subjective evaluation of sweating was conducted using the Hyperhidrosis Disease Severity Scale and Numeric Rating Scale in 4 body areas: the face, palms, armpits and abdomino-lumbar area. Objective evaluation of sweating was performed using gravimetry.
Results: The prevalence of hyperhidrosis in gravimetric measures was 1.12%. In subjective evaluation hyperhidrosis (HDSS 3 or 4) was present in 11.17% of cases. There was no significant difference in subjective evaluation of hyperhidrosis between men and women (15% vs. 9.24%; p = 0.32). In gravimetry men showed a higher perspiration rate on the face (5.85 vs. 3.38; p < 0.05) and in the armpits (17.27 vs. 9.12; p < 0.05). Individuals with body mass index ≥ 25 kg/m2 reported hyperhidrosis more often (28% vs. 8.44%; p < 0.05); however, in gravimetric evaluation, beside the facial area, no significant differences in above-mentioned groups were observed.
Conclusions: There is a discrepancy between subjective and objective methods of evaluating sweating.

Surgical treatment of compensatory hyperhidrosis: Retrospective observational study.

Medicine (Baltimore). 2020 Oct 16;99(42):e22466

Authors: Moon MH, Hyun K, Park JK, Lee J

Abstract
Compensatory hyperhidrosis is a debilitating postoperative condition occurring in 30% to 90% of patients with primary hyperhidrosis. The most appropriate treatment for compensatory hyperhidrosis remains controversial.Between January 2018 and December 2019, 44 patients with intractable compensatory hyperhidrosis underwent diffuse sympathicotomy (DS). In the early study periods, DS was performed sparsely (limited DS) to avoid possible adverse effects (right R5/7/9/11, left R5/6/8/10). In the late study periods, levels of surgical interruption were further modified to maximize sympatholytic effects (extended DS; bilateral R5/6/7/8/9/10/11). Patients were followed up for symptom resolution. For objective evidence of improved hyperhidrosis, thermographic images were taken for 7 patients.Immediate resolution of compensatory hyperhidrosis was achieved in 81% of patients, as determined at the 1 to 2 week postoperative visit. With a median follow-up of 22.7 months, compensatory hyperhidrosis continued to be resolved in 46% (n = 20). Logistic regression analysis showed that persistent resolution of compensatory hyperhidrosis was independently predicted by extended DS (odds ratio, 25.67, 95% CI, 1.78-1047.6; P = .036). The presence of gender, BMI, isolated compensatory hyperhidrosis, distribution of sweating, prior operation type, reoperation interval, and same-day lumbar sympathectomy failed to gain statistical significance on maintaining persistent resolution of compensatory hyperhidrosis. No patients experienced surgery-related side effects. Thermographic images obtained before/after surgery in 10 patients showed successful denervation and sweat diminishment.This study shows the safeness and effectiveness of DS for treating compensatory hyperhidrosis, representing a new treatment option. Future research should be directed at confirming a promising result of extended DS with further follow-up.

Can we predict the compensatory hyperhidrosis following a thoracic sympathectomy?

Can we predict the compensatory hyperhidrosis following a thoracic sympathectomy?

Indian J Thorac Cardiovasc Surg. 2019 Apr;35(2):190-195

Authors: Kara M, Kose S, Cayirci CE, Koksal A

Abstract
Background: Primary hyperhidrosis is a functionally and socially disabling condition resulting in social embarrassment and low quality of life. Thoracic sympathectomy is a definitive choice of treatment with favorable results. However, patients may face another embarrassing condition following surgery as compensatory hyperhidrosis which has no definitive treatment. The predictors of compensatory hyperhidrosis are controversial and remain unclear.
Patients and methods: A total of 74 patients underwent a videothoracoscopic sympathectomy for primary hyperhidrosis. We statistically analyzed our patients with correlations and uni-multivariate logistic regression models to outline the possible predictors of compensatory hyperhidrosis.
Results: A total of 45 (60.8%) patients had compensatory hyperhidrosis. The correlations showed that patients, with age greater than 21 years (P = 0.018), with body mass index (BMI) greater than 22 kg / m2 (P = 0.045), with isolated facial hyperhidrosis (P = 0.044), and with smoking status (P = 0.015), had significantly greater rates of compensatory hyperhidrosis. Similarly, the significant univariate predictors of compensatory hyperhidrosis were age > 21 (P = 0.020), BMI > 22 kg / m2 (P = 0.048), and the presence of smoking status (P = 0.015). Multivariate analysis revealed only smoking as a predictor within the threshold of significance (P = 0.078).
Conclusion: The clinical predictors of compensatory hyperhidrosis following a thoracic sympathectomy appear as older age, greater body mass index, and smoking.

Efficacy and Tolerability of 20% Aluminum Sesquichlorohydrate vs 20% Aluminum Chloride for the Treatment of Axillary Hyperhidrosis: A Randomized Controlled Trial.

Dermatol Ther. 2020 Sep 29;:e14354

Authors: Thianboonsong T, Kanokrungsee S, Paichitrojjana A, Udompataikul M, Kamanamool N, Rojhirunsakool S

Abstract
This study evaluated the efficacy and tolerability of topical aluminum sesquichlorohydrate (AS) when compared to aluminum chloride (AC) as a treatment for primary axillary hyperhidrosis. Twenty subjects were included in this randomized, controlled, split-side 8-week study. All participants applied 20% AS and 20% AC lotions in their axillae (one treatment per axilla) every night for 2 weeks; next, the application was reduced to three times a week for 4 weeks. The assessment was performed using the sweating intensity visual scale (SIVS), hyperhidrosis disease severity score (HDSS), patient satisfaction score, and the appearance of adverse effects on weeks 0, 1, 2, 4, 6, and 8. Both AS as well as AC application showed positive results, significantly differing from the baseline, as assessed using SIVS, HDSS, and patient satisfaction score at every follow-up visit; however, no significant difference was observed between the AS and AC groups at any follow-up visit. The mean time of response was 1.14 weeks for both treatments. A side effect was observed in one subject (5%), who reported itching on the AC axilla. The therapeutic effects persisted even after reducing the frequency of application and lasted for at least two weeks after cessation of use. In conclusion, topical 20% AS demonstrated similar efficacy to topical 20% AC in the treatment of primary axillary hyperhidrosis, with a high safety profile. This article is protected by copyright.

Oxybutynin in primary hyperhidrosis: a long-term real-life study.

Dermatol Ther. 2020 Sep 27;:e14344

Authors: Almeida ART, Ferrari F, Restrepo MVS, Rocha VB

Abstract
Hyperhidrosis is a condition of excessive sweating beyond physiological parameters that can seriously impair quality of life. This study aims to evaluate the oral oxybutynin effectiveness in hyperhidrosis, besides its tolerance and safety. In a real-life long-term study, thirty patients with primary hyperhidrosis and Hyperhidrosis Disease Severity Scale (HDSS) with score of at least two were submitted to a questionnaire to assess demographic data, HDSS and side effects of oxybutynin. Most patients were women (n = 23, 76.7%), median age was 40y (range 12-70, SD 17.5) and 17(56.7%) had family history of hyperhidrosis. The most common hyperhidrosis form was axillary (n = 15, 50.0%), followed by palmoplantar (n = 8, 26.7%), cranio-facial (n = 11, 36.7%) and trunk (n = 5, 16.7%). Median duration of treatment was 2.4y (range 1-6y, SD 1.3). Thus, all patients used oxybutynin for at least one year, 30% for two years, 20% three years, 17% four years and 3% six years. There was a significant improvement in HDSS score of patients (P < 0.001). This real life study suggests that oxybutynin is effective and safe for treatment of hyperhidrosis, both in children and adults, with mild and tolerable side effects, with significant improvement in HDSS.
