Abstract
BACKGROUND: Benign joint hypermobility syndrome (BJHS) is one of the most common hereditary connective tissue disorders in children in which autonomic nervous system involvement has been reported. This study aimed to evaluate the frequency of primary focal hyperhidrosis in children with BJHS.
METHODS: This observational-analytical study was conducted in a case-control setting on children aged 3 to 15 years in 2018 at Mofid Children’s Hospital, Tehran, Iran. Benign joint hypermobility syndrome was diagnosed according to the Brighton criteria; then, the patients referred to a dermatologist for evaluation of hyperhidrosis.
RESULTS: In total, 130 eligible patients with confirmed BJHS and 160 age- and sex-matched healthy subjects were enrolled in this study. Primary focal hyperhidrosis (PFH) was seen in 56.2 and 16.3% of the cases and controls, respectively, indicating a significant difference (P < 0.05). The severity of hyperhidrosis did not differ between the two groups.
CONCLUSION: Although the results of the study showed a significant correlation between BJHS and PFH, more comprehensive studies are needed to confirm these findings.

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.

New sympathicotomy for prevention of severe compensatory hyperhidrosis in patients with primary hyperhidrosis.

J Thorac Dis. 2020 Mar;12(3):765-772

Authors: Han JW, Kim JJ, Kim YH, Kim IS, Jeong SC

Abstract
Background: Primary hyperhidrosis (PH) is characterized by excessive and uncontrollable secretion in the eccrine sweat glands of the craniofacial region, armpits, hands, and feet. Sympathicotomy is the most effective treatment for severe PH; however, compensatory hyperhidrosis (CH) remains the most devastating postoperative complication. The purpose of the present study was to suggest a new sympathicotomy method for PH to prevent severe CH.
Methods: From March 2014 to December 2018, a total of 212 patients were included in the study. R2 (53 cases) sympathicotomy for craniofacial hyperhidrosis and R3 (79 cases) or R4 (80 cases) sympathicotomy for palmar hyperhidrosis using the thoracoscopic technique were performed, respectively. Sympathicotomy was performed using two different methods (conventional 145 cases and new 67 cases). Expanded sympathicotomy was performed as the new method (67 cases), which was divided into two groups (partial- and full-expanded sympathicotomy). Operative effectiveness was evaluated by a reduction in percentage of post-operative sweating compared with pre-operative sweating and groups were divided into complete and incomplete sweat reduction characteristics. Complete sweat reduction was defined as sweat reduction ≥80% compared with preoperative sweating. The degrees of CH were classified as negligible, mild bothering (tolerable), and severe bothering (intolerable). Data on preoperative subject characteristics, disease status, operative technique, and postoperative outcomes were gathered using medical records and telephone surveys.
Results: According to sympathicotomy techniques, the conventional procedure (non-expanded sympathicotomy) was performed in 145 cases and the new expanded sympathicotomy procedure was performed in 67 cases (partial-expanded sympathicotomy 28 cases; full-expanded sympathicotomy 39 cases). Craniofacial hyperhidrosis was significantly more prevalent in the older group and in female patients (P<0.001 and P=0.007, respectively). Sympathicotomy was significantly more effective in palmar hyperhidrosis than craniofacial hyperhidrosis (P<0.001). CH was significantly more severe in craniofacial hyperhidrosis than palmar hyperhidrosis after sympathicotomy (P<0.001). In craniofacial hyperhidrosis, there was no significant difference in sweat reduction and CH between conventional and the expanded sympathicotomy techniques (P=0.177 and P=0.474, respectively). In palmar hyperhidrosis, there was no significant difference in sweat reduction between the conventional and the expanded sympathicotomy (P=0.178), however, degree of CH in the conventional technique was significantly more severe than in the expanded technique (P=0.001). Regarding comparison between partial- and full-expanded sympathicotomy, there was no significant difference in sweat reduction between partial-, and full-expanded sympathicotomy; however, CH was significantly more severe in partial-expanded sympathicotomy (craniofacial hyperhidrosis P=0.006; palmar hyperhidrosis P<0.001). Irrespective of hyperhidrosis types, there was no significant difference in sweat reduction between full-expanded and the others (non-expanded and partial-expanded sympathicotomy), however, full-expanded sympathicotomy showed a significantly less degree of CH than non-expanded and partial-expanded sympathicotomy (craniofacial, P=0.002; palmar, P<0.001).
Conclusions: Full-expanded sympathicotomy is a safe and feasible treatment that shows a significant decrease in the degree of CH with the same effect in sweat reduction in both craniofacial and palmar hyperhidrosis. Importantly, no severe CH developed after a full-expanded sympathicotomy without any major postoperative complications.

Robotic Staged Bilateral Selective Postganglionic Sympathectomy for Upper-Extremity Hyperhidrosis.

Surg Technol Int. 2020 Apr 06;36:

Authors: Gharagozloo F, Meyer M, Tempesta B

Abstract
PURPOSE: The prevalence of compensatory hyperhidrosis (CH) has been reported to be as high as 80% in patients following thoracic sympathectomy for upper-extremity hyperhidrosis. The CH rate is 7.2% with simultaneous bilateral robotic selective dorsal sympathectomy. We reviewed the results in patients who underwent staged bilateral robotic selective dorsal sympathectomy (SBRSS).
METHODS: A case series analysis of patients who underwent SBRSS was performed. A surgical robot was used to divide the postganglionic sympathetic fibers and communicating rami to intercostal nerves 2, 3, and 4. The sympathetic chain was left intact. The operation was performed on the dominant side, and the same procedure was then performed on the contralateral side after 4 weeks. The success of the sympathectomy was determined by intraoperative temperature measurement, patient interviews, and the Hyperhidrosis Disease Severity Scale.
RESULTS: There were 47 patients (22 men, 25 women), with a mean age of 22 ± 3 years. Minor complications were seen in 4% of patients. One patient had transient heart block. One patient had transient partial Horner’s syndrome. Forty percent of patients had transient CH after the first surgery, and 45% had transient CH after sympathectomy on the contralateral side. There were no deaths. The median hospitalization was 3 days. At a mean follow-up of 28 ± 6 months, 46/47 patients (98%) had sustained relief of hyperhidrosis. In one patient (1/47, 2%), hyperhidrosis recurred on the first operated side. One patient (2%) exhibited sustained CH.
CONCLUSION: SBRSS is associated with a lower rate of CH than when the procedure is performed bilaterally in a simultaneous fashion. This procedure is associated with the lowest reported rate of CH.

Abstract
BACKGROUND AND OBJECTIVE: Hyperhidrosis (HH) is associated with impairments in quality of life (QOL) and elevated anxiety. Microwave thermolysis is a newer treatment that reduces sweating, yet effects on QOL and emotional symptoms have not been examined. Two treatment sessions are recommended to achieve 80% amelioration of clinical HH. We hypothesized that microwave thermolysis would reduce sweat severity, improve QOL, and reduce anxiety in young adults suffering from axillary HH in a prospective clinical trial.
STUDY DESIGN/MATERIALS AND METHODS: We enrolled 24 young adults (mean age = 23.57 years, 54% female) with elevated scores on the Hyperhidrosis Disease Severity Scale. All participants received one session of microwave thermolysis, and 83% received two sessions. Participants completed measures of sweat severity, QOL, generalized anxiety, social anxiety, social avoidance, and anxious/depressive mood symptoms at baseline; post-first treatment; and following second treatment.
RESULTS: At baseline, all participants had severe sweating; 87.5% had impaired QOL, 75% had elevated social anxiety, 50% with generalized anxiety, 48% with social avoidance, and 38% with anxious/depressed mood. Paired samples t tests indicated significant improvements from baseline to first procedure, including decreased sweating (t(21) = 5.68, P < 0.001), improved QOL (t(23) = 4.97, P < 0.001), and decreased generalized anxiety (t(23) = 8.11, P < 0.001), social anxiety (t(22) = 4.55, P < 0.001), mood symptoms (t(21) = 3.81, P = 0.001), and social avoidance (t(22) = 3.12, P = 0.005). After second treatment, further improvements were noted in sweating (t(18) = 3.28, P = 0.004) and QOL (t(18) = 3.83, P = 0.003), and a marginal trend for generalized anxiety (t(19) = 1.96, P = 0.064).
CONCLUSION: There were significant improvements in sweat severity, skin-specific QOL, generalized anxiety, social anxiety, anxious/depressive symptoms, and social avoidance. The majority of the psychosocial benefit appears to emerge after one treatment of microwave thermolysis, whereas the level of sweat severity and QOL continued to show further improvements after a second treatment. Results would suggest that although two microwave thermolysis sessions are needed for maximal treatment optimization of axillary HH, patients may experience significant benefits in improving psychosocial functioning after just one session.

Long-term efficacy and safety of topical glycopyrronium tosylate for the treatment of primary axillary hyperhidrosis: Post hoc pediatric subgroup analysis from a 44-week open-label extension study.

Pediatr Dermatol. 2020 Mar 08;:

Authors: Hebert AA, Glaser DA, Green L, Hull C, Cather J, Drew J, Gopalan R, Pariser DM

Abstract
BACKGROUND/OBJECTIVES: Glycopyrronium tosylate (GT) cloth, 2.4% is a topical anticholinergic approved in the United States for primary axillary hyperhidrosis in patients ≥9 years. This post hoc analysis evaluated long-term response (efficacy and safety) in pediatric patients (≥9 to ≤16 years) to GT in the 44-week, open-label extension (NCT02553798) of two, phase 3, double-blind, vehicle-controlled, 4-week trials (NCT02530281, NCT02530294).
METHODS: In the double-blind trials, patients ≥9 years with primary axillary hyperhidrosis were randomized 2:1 to once-daily GT:vehicle. Those who completed the study could receive open-label GT for up to an additional 44 weeks. Safety assessments included treatment-emergent adverse events (TEAEs) and local skin reactions (LSRs). Descriptive efficacy assessments included gravimetrically measured sweat production, Hyperhidrosis Disease Severity Scale response (≥2-grade improvement), and Children’s Dermatology Life Quality Index.
RESULTS: Of 43 pediatric patients completing either double-blind trial, 38 (88.4%) entered the open-label extension (age, years: 9 [n = 1], 12 [n = 2], 13 [n = 7], 14 and 15 [n = 9 each], 16 [n = 10]). The safety profile observed was similar to the double-blind trials. Most TEAEs (>95%) were mild/moderate, related to anticholinergic activity, and infrequently led to discontinuation (n = 1/38 [2.6%]). No pediatric patients experienced a serious TEAE. Most anticholinergic TEAEs did not require a dose modification and resolved within 7 days. Approximately, one-third of patients (n = 13/38 [34.2%]) had LSRs; most were mild/moderate in severity. Improvements in efficacy measures were maintained from the double-blind trials.
CONCLUSIONS: Long-term, once-daily GT for up to 48 weeks (4-week double-blind plus 44 week open label) provides a noninvasive, well-tolerated treatment option for pediatric patients with primary axillary hyperhidrosis.

“Psychodermatology” knowledge, attitudes, and practice among health care professionals

Abstract

Psychiatric disorders are prevalent in dermatology patients. Psychodermatology is the body of knowledge at the intersection of psychiatry and dermatology practice. The purpose of this literature review was to assess the knowledge, attitudes, and practices of health care professionals regarding psychodermatology. A search of relevant articles was conducted in PubMed, CINAHL, ERIC, and PsychInfo databases using a comprehensive set of search terms. Studies were included if (1) study participants were health care professionals, (2) studies contained data that could be extracted, and (3) studies were published in peer-reviewed journals. A review of study findings was conducted. A total of nine studies were included in the review. Studies were conducted in several countries. Findings from the review confirmed that providers frequently reported psychocutaneous disorders in their practice. There were, however, gaps and variations in providers’ knowledge base and level of comfort treating these patients. Further, providers acknowledged a lack of training in the practice of psychodermatology. The findings from this review suggest that health care professionals from multiple areas of the world may lack a full understanding, level of comfort, and proper training in psychodermatology. Improving the knowledge base and increasing level of comfort in treating psychodermatological disorders can improve the practice of psychodermatology amongst providers. Further, addressing knowledge and comfort level among providers through training and continuing education may improve outcomes for patients with psychocutaneous disorders.

Abstract
BACKGROUND: Primary axillary hyperhidrosis has limited noninvasive, effective, and well-tolerated treatment options.
OBJECTIVE: To evaluate the topical treatment of axillary hyperhidrosis with the novel anticholinergic sofpironium bromide.
METHODS: A phase II, multicenter, randomized, controlled, double-blinded study. Participants were randomized to one of three doses or vehicle, with daily treatment for 42 days. Coprimary endpoints were the percentage of participants exhibiting ≥1-point improvement in Hyperhidrosis Disease Severity Measure-Axillary (HDSM-Ax; logistic regression), and change in HDSM-Ax as a continuous measure (ANCOVA). Pair-wise comparisons were one-sided with alpha=0.10.
RESULTS: At end-of-therapy, 70%, 79%, 76% and 54% of participants in the 5%, 10%, 15% and vehicle groups exhibited ≥1-point improvement in HDSM-Ax (P<0.05). Least-square mean (SE) changes in HDSM-Ax were -2.02 (0.14), -2.09 (0.14), 2.10 (0.14), and -1.30 (0.14) (all P≤0.0001). Most treatment-related adverse events were mild or moderate.
LIMITATIONS: Not powered to detect changes in gravimetric sweat production.
CONCLUSION: Sofpironium bromide gel produced meaningful reductions in hyperhidrosis severity and had an acceptable safety profile.
