Abstract
The condition of most patients with hyperhidrosis (HH) is known to worsen with increased temperature. However, most prior studies of oral glycopyrrolate (OGly) for the treatment of HH have assumed a stable treatment protocol, without taking into account seasonal variations in temperature. The main aim of this study is to evaluate the outcomes derived from performing a seasonal adjustment of the dose of OGly for patients with HH. A prospective study of patients who began OGly for HH, and maintained treatment for at least one year, was performed. All patients had experienced treatment failure with oral oxybutynin. All were recommended to vary the dose of medication according to the time of year. Of the thirty-five patients included in the study, twenty (57.14%) varied the dose. Those with palmar and plantar HH had a greater propensity to do so. The patients who varied the dose according to the time of year were significantly more likely to report an “Excellent” response after 12 months of treatment. The frequency of adverse effects was 71.4% with no significant differences among the study groups. However, there was a significantly higher proportion of adverse effects other than oral xerosis in the group that did not vary the dose. This article is protected by copyright. All rights reserved.

Abstract
Background: Hyperhidrosis is due to the hyperactive autonomic stimulation of the sweat glands in response to stress. Primary hyperhidrosis is a common yet psychologically disabling condition. This study will describe our experience in managing hyperhidrosis via endoscopic thoracic sympathectomy (ETS). Methods: The information was obtained from the patient records from 1 st January 2011 until 31 st December 2016. Pertinent information was extracted and keyed into a study proforma. Results: 150 patients were operated on but only 118 patients were included in this study. The mean age was 22.9±7.3 years. The majority (54.2%) had palmar-plantar hyperhidrosis and 39.8% had associated axillary hyperhidrosis. Excision of the sympathetic nerve chain and ganglia were the main surgical technique with the majority (55.9%) at T2-T3 level. Mean ETS procedure time was 46.6±14.29 minutes with no conversion. Surgical complications were minimal and no Horner’s Syndrome reported. Mean hospital stay was 3.5±1.05 days. The majority of patients (67.8%) had only one follow-up and only half of the study sample (58.5%) complained mild to moderate degree of compensatory sweating, even though the long-term resolution is yet to be determined by another study. Following ETS, 98.3% of patients had instant relief and resolved their palmar hyperhidrosis. Predictors of CS were sympathectomy level and follow-up. The odds of reporting CS was 2.87 times in patients undergoing ETS at the T2-T3 level compared to those undergoing ETS at the T2-T4 level. The odds of reporting CS was 13.56 times in patients having more than one follow-up compared to those having only one follow-up. Conclusion: We conclude that ETS is a safe, effective and aesthetically remarkable procedure for the treatment of primary hyperhidrosis with only half of the patients developing mild to moderate degree of CS. Significant predictors of CS were sympathectomy level during ETS and frequency of follow-up after ETS.

Long‐term results of the treatment of primary hyperhidrosis with oxybutynin: follow‐up of 1,658 cases

Abstract

Background
Hyperhidrosis (HH) is characterized by exaggerated sweating in a specific region due to hyperfunction of the sweat glands. In the late 2000s, we started treating patients with an anticholinergic, oxybutynin, that was not being used until then.

Objectives
To present, after 12 years of utilizing this medication in our service, the substantial experience obtained with the use of oxybutynin as an initial treatment of HH in a large series of 1,658 patients.

Methods
We analyzed 1,658 patients treated with oxybutynin for HH from May 2006 to June 2018. The patients were divided into four groups according to the main site of HH: the plantar group, the axillary group, the facial group, and the palmar group. To measure the degree of satisfaction, a quality of life (QoL) questionnaire was used.

Results
Pre‐treatment QoL was poor or very poor in more than 94% of the cases, and the palmar group had the worst quality of life. After treatment, we observed an improvement in the quality of life in 77% of patients. More than 70% of the patients in all groups present moderate or optimal subjective clinical improvement in sweating after treatment. The group with the best result was the facial group. Intense dry mouth was reported in 24.9% of all patients in all groups.

Conclusions
This study included a large number of patients followed for a long period and demonstrated the good effectiveness of treatment with oxybutynin for hyperhidrosis in the main sites of sweating.

Abstract
BACKGROUND: Hyperhidrosis is a pathological condition defined by excessive sweating beyond thermoregulatory physiological needs, which can cause substantial psychological impact and impairment of daily activities. Studies regarding its prevalence, however, are scarce and vary widely in their findings. The population of medical students is a particularly interesting subset for its recurring demand of physical contact during patient examination or procedures, and the potential for professional adversity. We aimed at furthering the comprehension of this disease prevalence and characteristics among medical students.
METHODS: Questionnaires inquiring about the presence and characteristics of Primary Hyperhidrosis (PH) were applied through either written or digital means to all eligible medical students enrolled in three Medical Schools in the State of Rio de Janeiro who agreed to take part in the study. Demographic data regarding gender, ethnicity, current age, weight and height was collected in addition to clinical data (sweat site, age of onset, familial history, severity and previous treatments). Severity was evaluated through the Hyperhidrosis Disease Severity Scale (HDSS) and a symptoms survey.
FINDINGS: Our response rate was roughly 1/3 of all eligible students (900/2700). PH prevalence was 20.56% (185/900). It was similar between men and women (23.08% and 19.41%, respectively) and strongly associated with family history of the disease (Prevalence Ratio of 4.27). Regarding ethnicity, of the total sample 73.78% (664/900) self-declared white, among which 19.28% (128/664) had PH. Mixed-race and other ethnicities encompassed 26.22% (236/900) of the sample, among which 24.15% (57/236) had PH. Most positive subjects (64.32%) presented associated forms of PH. Overall involvement of each site (both associated and isolated) was: 63.78% axillary, 50.81% palmar, 43.24% plantar, 20.54% craniofacial, 18.38% facial flushing and 2.16% gustatory sweating. Mean current age was 23.11(±4.04) years for PH patients, and age of onset was ≤18 years in 93.94% of cases. Regarding body mass index (BMI), 71.09% of PH patients had BMI<25kg/m2 and only 4.69% presented BMI≥30kg/m2, none ≥35kg/m2. Some degree of life quality impairment was reported by 89.20% of PH patients, and 23.89% had HDSS 3 or 4 (moderate to severe).
CONCLUSIONS: PH prevalence among Rio de Janeiro medical students was 20.56%, similar between men and women, predominating associated presentations, axillary, palmar and plantar sites, strong familial history, age of onset before 18 years, and some degree of life impairment.

Abstract
INTRODUCTION: Hyperhidrosis (HH) is associated with physical and psychological restrictions. The treatment includes both conservative and surgical methods and aims to permanently improve the quality of life (QoL) of those affected. Endoscopic sympathetic blockade (ESB) is an established surgical therapeutic method and is considered effective when conservative treatment options fail. The aim of our study was to comprehensively analyse the QoL alteration and patient satisfaction after ESB and to identify the corresponding influencing factors.
METHODS: From July 2008 to April 2016, 105 patients were operated for treatment-refractory HH. In all cases, an ESB was performed according to the HH form and the STS expert consensus (STS: Society of Thoracic Surgeons). QoL and hyperhidrosis status were selectively analysed pre- and postoperatively and evaluated using detailed questionnaires (a self-developed questionnaire, SF36, DLQI, Hyperhidrosis LQ (HidroQoL)). Statistical processing was performed with SPSS Statistics version 21.0.0.2 for Windows (Armonk, NY: IBM Corp.). Descriptive statistical analysis and nonparametric tests were used.
RESULTS: 105 patients who underwent bilateral ESB between July 2008 and April 2016 were evaluated: 73 women (69.5%) and 31 men (29.5%) with median age of 26 years (range: 16 - 64 years). Of the 105 patients who underwent bilateral ESB, 12 patients had focal Hyperhidrosis palmar and axillar (12.4%), 20 had Hyperhidrosis palmo-plantar (19.0%), 47 had Hyperhidrosis palmoplantar and axillar (44.8%), 11 had Hyperhidrosis axillar (10.5%), and 14 had Hyperhidrosis facial (13.3%). HydroQoL scores showed improvement in all forms of HH. All patient groups demonstrated improvement in DLQI, while the LQ analysis of SF36 showed an improvement in social functioning and mental well-being in all forms of HH other than HA. 86.7% of patients (n = 91) were satisfied with their postoperative outcome. Compensatory sweating (CS) was observed in 76.2% of cases (n = 80), without a clear LQ impact. No significant correlation between CS and the hyperhidrosis form was found.
CONCLUSIONS: ESB is associated with a long-time improvement in social functioning, psychological well-being, and high patient satisfaction. The onset of CS has no clear correlation to QoL and patient satisfaction.

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.
