To avoid compensatory hyperhidrosis after sympathetic surgery for craniofacial hyperhidrosis.

J Thorac Dis. 2020 May;12(5):2529-2535

Abstract
Background: Endoscopic thoracic sympathectomy (ETS) has not been widely adopted for treating craniofacial hyperhidrosis (CFH) due to its known postoperative complication, compensatory hyperhidrosis (CH). In this study, we evaluated whether the autonomic nerve analysis data via pre-ETS heart rate variability (HRV) test can predict post-ETS CH in patients with CFH.
Methods: From October 2017 to March 2019, we consecutively included CFH patients who underwent ETS and received preoperative HRV. In this prospective observational study, we evaluated those who developed CH 3 months postoperatively. The CH grades were categorized into none, mild, moderate, and severe.
Results: A total of 53 patients were included; the mean age was 42.5±13.2 years, and there were 41 males (77.4%). Twenty-six (49.1%) patients had a post-ETS CH grade of greater than moderate (moderate and severe). We further classified the group into trivial and serious compensation, based on the CH grade for comparison. Among the various HRV values, low frequency/high frequency (LF/HF) value was the only one that achieved statistical significance (P=0.025). Moreover, among those in the trivial compensatory group, 23 (85.2%) patients had an LF/HF value between 0.66 and 2.60, and therefore, were included in the autonomic balanced group. On the other hand, among those in the serious compensatory group, 24 patients (92.3%) had an LF/HF value of less than 0.66 and greater than 2.60, and thus, in the autonomic dysfunction group.
Conclusions: According to the present study, HRV test, especially the HF/LF value, appears to be a useful test in predicting post-ETS serious CH.

The impact of adolescents’ everyday life experiences on their primary hyperhidrosis treatment- a qualitative study.

J Dermatolog Treat. 2020 Jul 06;:1-27

Authors: Trettin B, Hansen J, Bygum A

Abstract
Introduction: Hyperhidrosis is a disease affecting around 5% of the western population. The qualitative field within hyperhidrosis among adolescents has been sparsely investigated. The aim of this study was to investigate the impact of adolescent hyperhidrosis patients’ everyday life experiences on their hyperhidrosis treatment.Methods: Qualitative, semi-structured interviews were carried out. In total, 10 adolescents, aged 12-18 years, participated in the study. Data were analyzed using a set of inseparable activities as described by Van Manen.Results: Three main themes were identified to represent common shared experiences across participants. The first theme was related to the impact of hyperhidrosis on the physical and psychological dimensions of life as it negatively affected both physical abilities and one’s self-concept. Having hyperhidrosis was experienced as living a life in secrecy, characterized by individual routines for concealment and isolation in order to protect social identity.Conclusion: The large negative impact of hyperhidrosis on adolescents is a strong justification for treatment of the disease. The substantial emotional distress suggests that treatment may need to include psychological support.

Association between Reflux Esophagitis Incidence and Palmar Hyperhidrosis.

Int J Environ Res Public Health. 2020 Jun 23;17(12):

Authors: Cheng CG, Chien WC, Yu CP, Chung CH, Cheng CA

Abstract
The autonomic dysfunction in palmar hyperhidrosis (PH) includes not only sympathetic overactivity but also parasympathetic impairment. A decrease of parasympathetic tone has been noted in gastroesophageal reflux disease of neonates and adults. Patients with reflux esophagitis have a defective anti-reflux barrier. The association between reflux esophagitis and PH is deliberated in this article. The National Health Insurance Database in Taiwan was used. At first-time visits, PH patients were identified by the International Classification of Disease, 9th Revision, Clinical Modification disease code of 780.8 without endoscopic thoracic sympathectomy. Patients were matched by age and gender as control groups. The reflux esophagitis incidence was assessed using disease codes 530.11, 530.81, and 530.85. The factors related to reflux esophagitis were established by the Cox proportional regression model. The risk of reflux esophagitis in PH patients had a hazard ratio of 3.457 (95% confidence interval: 3.043-3.928) after adjustment of the other factors. We confirmed the association between reflux esophagitis and PH. Health care providers must be alerted to this relationship and other risk factors of reflux esophagitis to support suitable treatments to improve the quality of life of patients.

Fractional CO2 laser-assisted Botulinum toxin type A delivery for the treatment of primary palmar hyperhidrosis.

Lasers Med Sci. 2020 Jun 17;:

Authors: Junsuwan N, Manuskiatti W, Phothong W, Wanitphakdeedecha R

Abstract
Intradermal injections of botulinum toxin type A (BTX-A) have been used successfully to treat patients with primary palmoplantar hyperhidrosis (PPH). However, problems with local injections of BTX-A for palmar hyperhidrosis include injection pain and reduced palmar muscle strength. This case series describes three patients with PPH. Patients were followed up for 3 months and assessed using the minor iodine starch test and the visual analog scale (VAS). Over two sessions within a 2-week interval, all patients received treatment on one palm, while the other palm served as the untreated control. Treated palms received fractional CO2 laser therapy and immediate post-operative topical application of BTX-A solution for a total of 50 units. Sweat production was assessed based on the size of the sweat-producing area (measured by the minor iodine starch test) and subjective assessment of sweat production using the visual analog scale (VAS) at baseline, 2 weeks after the first treatment, and 1, 2, and 3 months after the second treatment. In the BTX-A-treated palm, the decrease in the mean sweat production was 51.6% at 2 weeks after the first treatment, and 88.5%, 67.8%, and 52.9%, at 1, 2, and 3 months after the final treatment when compared to the baseline. In the untreated palms, the decrease in the mean sweat production was 2% on all follow-ups when compared to the baseline. No adverse effect was observed in any patient. Fractional CO2 laser is a safe technique for BTX-A delivery on the palm area and is demonstrated to be safe and effective in decreasing sweat secretion of hyperhidrosis palm.

Bilateral R5-R8 sympathectomy for compensatory hyperhidrosis: complications and patient satisfaction.

Rev Col Bras Cir. 2020;47:e20202398

Authors: Vasconcelos CFM, Aguiar WS, Tavares RM, Barbosa A, Cordeiro GG, Oliveira FSC, Ferraz ÁAB

Abstract
OBJECTIVE: The purpose of this study was to assess the quality of life of patients who had undergone bilateral thoracic sympathectomy from R5 to R8 as a treatment for severe and debilitating compensatory hyperhidrosis (CH).
METHODS: Twelve patients with severe and debilitating compensatory hyperhidrosis underwent extended sympathectomy (R5-R8) from September 2016 to May 2019 at the Hospital das Clínicas, Federal University of Pernambuco, Brazil. Outcomes such as the level of patient satisfaction with the operation, quality of life scores as well as postoperative complications were assessed.
RESULTS: There has been a substantial improvement in the quality of life score of 66% of the sample. In all four domains, a statistical significant difference was seen, regarding the relief of compensatory hyperhidrosis symptoms.
CONCLUSIONS: Extended sympathectomy from R5 to R8 was shown to be quite effective in most cases, leading us to believe that this approach could be a therapeutic option for severe compensatory hyperhidrosis.

Heart Rate Variability Assessment and Its Application for Autonomic Function Evaluation in Patients with Hyperhidrosis.

Eur Neurol. 2020 Jun 17;:1-8

Authors: Niwa ASM, Gregório ML, Leão LEV, de Godoy MF

Abstract
BACKGROUND: Pathophysiology mechanism of primary focal hyperhidrosis (PFHH) is controversial. Heart rate variability (HRV) could explain if there is a systemic component present. We aimed to investigate the functions of the autonomic nervous system in patients diagnosed with PFHH compared to controls using the analysis of HRV in the domains of time, frequency, and nonlinearity, as well as analysis of the recurrence plots (RPs).
METHODS: We selected 34 patients with PFHH (29.4 ± 10.2 years) and 34 controls (29.2 ± 9.6 years) for HRV analysis. Heart beats were recorded with Polar RS800CX monitor (20 min, at rest, in supine position), and RR intervals were analyzed with Kubios Premium HRV software. RPs were constructed with Visual Recurrence Analysis software. Statistical analysis included unpaired t test (p < 0.05).
RESULTS: Our results showed that HRV parameters in the 3 domains evaluated did not show any differences between the groups. The same was observed with RPs.
CONCLUSIONS: The findings suggest that PFHH, from the pathophysiological point of view, may be caused by peripheral involvement of the sympathetic nervous system (glandular level or nerve terminals), as there was no difference between the groups studied. More specific studies should help elucidate this issue.

Video-assisted thoracoscopic sympathectomy versus modified Wittmoser method in surgical management of primary hyperhidrosis.

J Cardiothorac Surg. 2020 Jun 10;15(1):133

Authors: Divisi D, Zaccagna G, Imbriglio G, Di Francescantonio W, De Vico A, Barone M, Crisci R

Abstract
PURPOSES: We compared two different surgical methods evaluating the effectiveness of procedures and the quality of life (QoL) of patients.
METHODS: From January 2010 to November 2017 we carried out 476 biportal video-assisted thoracoscopic surgery (VATS) approaches of sympathetic chain in 238 patients. One hundred and twenty-nine (54%) patients underwent conventional sympathectomy (CS) while 109 (46%) patients underwent sympathicotomy associated with the division of the rami communicantes (MWT). Quality of Life (QoL) was classified as follows: from 20 to 35 excellent; from 36 to 51 very good; from 52 to 68 good; from 69 to 84 poor; and > 84 very poor.
RESULTS: We noticed statistical significant reduction of complications comparing CS with MWT approaches (chest pain from 36.4 to 4.5%; paresthesias from 8.5 to 3.6%; bradycardia from 28.6 to 10%, respectively). The preoperative and postoperative QoL index evaluation revealed a statistically significant improvement after surgery (CS: 86 ± 2 versus 35 ± 1, p = 0.00001; MWT: 85 ± 1 versus 33 ± 2, p = 0.00001), with general satisfaction of the two techniques.
CONCLUSION: Modified Wittmoser method seems to be a valid alternative to conventional sympathectomy, minimizing the percentage rate of complications and showing significant effectiveness in the quality of life improvement.
