Abstract
Parkinson’s disease (PD) is a complex multisystem disorder with motor and non-motor symptoms (NMS). NMS may have an even greater impact on quality of life than motor symptoms. Subthalamic nucleus deep brain stimulation (STN-DBS) has been shown to improve motor fluctuations and quality of life, whereas the effects on different NMS have been less examined. Sleep disturbances and autonomic dysfunction are among the most prevalent NMS. We here report the efficacy of STN-DBS on sleep disturbances and autonomic dysfunction. In the parent trial, 60 patients were included in a single-center randomized prospective study, with MDS-UPDRS III and PDQ-39 as primary endpoints at 12 months of STN-DBS. Preplanned assessments at baseline and postoperatively at 3 and 12 months also included Parkinson’s Disease Sleep Scale (PDSS); Scopa-Aut; and MDS-UPDRS I, II, and IV. We found that STN-DBS had a significant and lasting positive effect on overall sleep quality, nocturnal motor symptoms and restlessness, and daytime dozing. Several aspects of autonomic dysfunction were also improved at 3 months postoperatively, although at 12 months only thermoregulation (sudomotor symptoms) remained significantly improved. We could not identify preoperative factors that predicted improvement in PDSS or Scopa-Aut. There was a close relationship between improved autonomic symptoms and improved quality of life after 1 year. NMS and especially sleep and autonomic dysfunction deserve more focus to improve patient outcomes further.

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

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.

Diagnosis, impact and management of hyperhidrosis including endoscopic thoracic sympathectomy.

Diagnosis, impact and management of hyperhidrosis including endoscopic thoracic sympathectomy.

Med J Malaysia. 2020 Sep;75(5):555-560

Abstract
INTRODUCTION: Hyperhidrosis is a disorder of excessive and uncontrollable sweating beyond the body’s physiological needs. It can be categorised into primary or secondary hyperhidrosis based on its aetiology. Detailed history review including onset of symptoms, laterality of disease and family history are crucial which may suggest primary hyperhidrosis. Secondary causes such as neurological diseases, endocrine disorders, haematological malignancies, neuroendocrine tumours and drugs should be adequately examined and investigated prior to deciding on further management. The diagnosis of primary hyperhidrosis should only be made only after excluding secondary causes. Hyperhidrosis is a troublesome disorder that often results in social, professional, and psychological distress in sufferers. It remains, however, a treatment dilemma among some healthcare providers in this region.
METHODS: The medical records and clinical outcomes of 35 patients who underwent endoscopic thoracic sympathectomy for primary hyperhidrosis from 2008 to 2018 in Department of Cardiothoracic Surgery were reviewed.
RESULTS: The mean age of the patients was 27±10.1years, with male and female distribution of 18 and 17, respectively. Fifty-one percent of patients complained of palmar hyperhidrosis, while 35% of them had concurrent palmaraxillary and 14% had palmar-plantar-axillary hyperhidrosis. Our data showed that 77% (n=27) of patients were not investigated for secondary causes of hyperhidrosis, and they were not counselled on the non-surgical therapies. All patients underwent single-staged bilateral endoscopic thoracic sympathectomy. There was resolution of symptoms in all 35 (100%) patients with palmar hyperhidrosis, 13(76%) patients with axillary hyperhidrosis and only 2 (50%) patients with plantar hyperhidrosis. Postoperatively 34.3% (n=12) of patients reported compensatory hyperhidrosis. There were no other complications such as pneumothorax, chylothorax, haemothorax and Horner’s Syndrome.
CONCLUSION: Clinical evaluation of hyperhidrosis in local context has not been well described, which may inadvertently result in the delay of appropriate management, causing significant social and emotional embarrassment and impair the quality of life of the subjects. Detailed clinical assessment and appropriate timely treatment, be it surgical or non-surgical therapies, are crucial in managing this uncommon yet distressing disease.
