Abstract
In this video, we demonstrate a case of a 21-year-old right-handed male who presented with palmar hyperhidrosis. His symptoms started at the age of 4 and progressively worsened throughout his life. Multiple medical treatments were used without significant benefit. His symptoms worsened to the limit that it affected his work, and lifestyle. The patient was taken to the operating room in a supine position with both arms abducted 90 degrees. The right and left chest were prepped and draped in a sterile fashion. The skin incision was done on the left side first, the left lung was isolated and two 5 mm thoracoports were placed in the 6th and 3rd intercostal spaces, respectively. CO2 insufflation was used to pressure of 6 mmHg for exposure. The chest was visualized and the sympathetic chain was identified. Ribs were counted and then using cautery at a low setting was used. The sympathetic chain was transected at the level of the head of the 2nd rib. Accessory nerves of Kuntz were identified and resected. CO2 was then evacuated from the left chest using a bronchial tube exchanger and Valsalva maneuver. The lung was completely re-inflated and skin was closed in normal fashion. The same procedure was repeated on the right side. A chest X-ray was obtained intraoperatively, and no pneumothorax was observed. At the end of the procedure, both upper extremities temperature probes showed a significant increase from baseline. Informed patient consent was obtained.

Primary hyperhidrosis prevalence and characteristics among medical students in Rio de Janeiro.

PLoS One. 2019;14(9):e0220664

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
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.

Assessment of craniofacial hyperhidrosis and flushing by sphenopalatine blockade – a randomized trial.

Rhinology. 2019 Sep 02;:

Abstract
BACKGROUND: Craniofacial hyperhidrosis (CFH) and flushing express nervous system autonomic dysfunction. Available reference treatments lack good compliance. The study objective was to investigate variations of CFH/flushing after two methods of sphenopalatine ganglion (SPG) blockade.
METHODOLOGY: CFH patients (n=25) were randomized in a ratio of 1:3 in two groups; 1) endoscopic application of topical lidocaine over SPG (TL; n=7); 2) endoscopic injection of lidocaine in the SPG (IL; n=18). CFH, flushing, rhinorrhoea, nasal obstruction, and smell detection were scored by Visual Analogue Scale (VAS). Nasal endoscopy, acoustic rhinometry, mucociliary transport test, smell/taste test, Schirmer test, Short Form-12, Chronic Skin Diseases Questionnaire, and Skin Satisfaction Questionnaire were also performed at visit 0, 1, 3 and 6 months.
RESULTS: At baseline, groups reported similar CFH VAS (TL: 89.3 plus or minus 17.5mm; IL: 85.7 plus or minus 22.1mm) or flushing VAS (TL: 52.7 plus or minus 30mm; IL: 59 plus or minus 33.8mm). After 6 months, the least squares mean of CFH VAS in IL was -38.1 (-47.3 to -28.9) compared to TL 1.9 (-12.2 to 15.9). However, flushing VAS did not improve. Any rhinological measure nor quality of life test showed significant changes. One patient presented controlled epistaxis intraoperatively during IL.
CONCLUSIONS: This preliminary study shows the sphenopalatine blockade injection as a safe procedure. Patients with CFH or flushing had significant improvement after lidocaine injection which lasted 6 months. Due to the small sample and the lack of objective measures more studies are needed.

Duration of Efficacy Increases with the Repetition of Botulinum Toxin A Injections in Primary Axillary Hyperhidrosis: A 15-year Study in 117 Patients.

Acta Derm Venereol. 2019 Aug 27;:

Authors: Berthin C, Maillard H

Abstract
Changes in the duration of efficacy of botulinum toxin A injections for primary axillary hyperhidrosis have not been studied in depth. The aim of this study was to assess such changes. In a retrospective cohort of 220 patients, seen over a 17-year period, duration of efficacy was recorded, including duration of efficacy of first and last injections. Of 220 patients, 117 fulfilled the study criteria (79 females and 38 males, age 17-79 years, mean age 38.3 years). Patients received 3-24 injections (mean 5.5). The duration of efficacy of the first injections was 3 weeks to 30 months (median 6 months), and the duration of efficacy of the final injections was 3 weeks to 66 months (median 8 months) (p < 0.001). An increase in duration of efficacy occurred in 62% of patients. Of the 20 patients with a follow up ≥10 years, the mean number of treatments was 8.25/patient; in 18 of these patients the duration of efficacy increased by > 50%. In conclusion, repeated botulinum toxin A injections lead to an increase in duration of efficacy without secondary decrease.

Genetic disposition to primary hyperhidrosis: a review of literature.

Arch Dermatol Res. 2019 Aug 21;:

Authors: Henning MA, Pedersen OB, Jemec GB

Abstract
Primary hyperhidrosis is a condition characterized by excessive sweating. The estimated prevalence is between 0.6 and 4.4%, and it can have economic, psychological, and social consequences for affected individuals. Family and genetic studies have suggested a genetic component in the inheritance of the disease. In this review, we summarize the current literature on genetic disposition to primary hyperhidrosis. We Identified 20 studies on Pubmed and Embase in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Probands reported a positive family history in 5.7-65% of cases, and the inheritance appeared to be either autosomal dominant or recessive. Individuals with palmoplantar phenotypes and a positive family history had a younger age of onset. Genetic linkage and genome-wide association studies have identified loci on chromosome 2, 14, and 16. However, the evidence is heterogeneous and limited. It seems that primary hyperhidrosis is polygenically inherited, and considering the impairment, further data to understand the genetic etiology of the disease are needed.

Abstract
BACKGROUND: This study aimed to evaluate the clinical efficacy and safety of endoscopic thoracic sympathicotomy and to explore strategies to decrease the incidence of transfer hyperhidrosis (TH).
METHODS: From January 2003 to July 2016, 10,275 patients with primary palmar hyperhidrosis underwent endoscopic thoracic sympathicotomy in 15 different institutions. We carried out a retrospective analysis of these patients who were grouped into group A, those with nonretained R2 (R2, R2-3, or R2-4 ablation), and group B, those with retained R2 (single R3 or R4 ablation).
RESULTS: All procedures were performed successfully. Both hands of all patients became warm and dry immediately after endoscopic thoracic sympathicotomy. Pneumothorax occurred in 146 patients, and 39 patients had intraoperative bleeding. Follow-up was carried out from 6 months to 13 years. A total of 531 patients (5.2%) were lost to follow-up. The effective rate for primary palmar hyperhidrosis was 100%. Palmar hyperhidrosis recurred in 73 patients (0.7%). Transfer hyperhidrosis appeared in 7,678 patients (78.8%). For groups A and B, the incidence of TH was 80.4% and 78.5%, respectively (P > .05), but the incidence of grade III+IV TH in group B (1.6%) was less than that in group A (4.8%; P < .001).
CONCLUSION: Endoscopic thoracic sympathicotomy is a minimally invasive, safe, and effective therapeutic method for primary palmar hyperhidrosis. Although the overall incidence of TH is high, the incidence of grade III to IV TH can be decreased by reserving R2, lowering the level of thoracic sympathicotomy, and single severing of R3 or R4.
