Front Surg. 2024 Oct 28;11:1402241. doi: 10.3389/fsurg.2024.1402241. eCollection 2024.

ABSTRACT

OBJECTIVE: This study compared the efficacy and complications of percutaneous radiofrequency ablation with anhydrous alcohol ablation of sympathetic nerves in treating hyperhidrosis of the head and palms.

METHODS: A retrospective analysis was conducted on 54 patients with primary hyperhidrosis in our department from June 2018 to June 2021, divided into a radiofrequency ablation group (30 cases) and an anhydrous alcohol ablation group (24 cases). Treatment outcomes were compared by analyzing the number of CT scans, effectiveness, and complications.

RESULTS: In the radiofrequency group, symptoms of bilateral hyperhidrosis significantly improved in 24 patients, with an 80% postoperative satisfaction rate. In the alcohol ablation group, symptoms significantly improved in 19 patients postoperatively, with a 79.2% satisfaction rate. There was no statistically significant difference in effectiveness or complications between the two groups (all P > 0.05). The number of CT scans in the radiofrequency group was 4.60 ± 0.56 and 6.08 ± 0.28 in the alcohol group, showing a statistically significant difference (P < 0.05).

CONCLUSION: This study concluded that both percutaneous radiofrequency ablation and alcohol ablation are effective methods for hyperhidrosis treatment, with similar effectiveness and complication rates, but the radiofrequency ablation group required fewer CT scans.

Pharmacologic properties and results of a clinical study of oxybutynin hydrochloride lotion (APOHIDE() Lotion 20%) as a novel treatment for primary palmar hyperhidrosis

Nihon Yakurigaku Zasshi. 2024;159(6):413-422. doi: 10.1254/fpj.24037.

ABSTRACT

APOHIDE® Lotion 20% is a topical agent for treating primary palmar hyperhidrosis that contains the active ingredient oxybutynin hydrochloride. Oxybutynin hydrochloride has anticholinergic effects and inhibits sweating by binding to the M3 receptor, a subtype of the muscarinic acetylcholine receptor, in eccrine sweat glands. The clinical response to oxybutynin hydrochloride treatment also involves N-desethyloxybutynin, an active metabolite of oxybutynin. A clinical study in Japanese patients with primary palmar hyperhidrosis showed superiority of APOHIDE® Lotion 20% over placebo, i.e., there were significantly more responders (i.e., patients with a reduction in sweat volume ≥50% from baseline) in the APOHIDE® Lotion 20% group (APOHIDE® Lotion 20% group: 52.8%, placebo group: 24.3%; treatment difference: 28.5%; P < 0.001, Fisher’s exact test). This and other clinical studies reported some adverse events (AEs) associated with the drug’s anticholinergic effects and some application site AEs, but most of the AEs were mild. Clinical response did not decrease with long-term (52-week) treatment, and only a few patients (2 of 125) discontinued treatment because of AEs. Taken together, study results indicate that APOHIDE® Lotion 20% may be an effective and safe new treatment option for patients with primary palmar hyperhidrosis.

A Pivotal Study on the Safety and Effectiveness of a Targeted Alkali Thermolysis Patch for Treatment of Primary Axillary Hyperhidrosis or Excessive Axillary Sweating

Dermatol Surg. 2024 Oct 31. doi: 10.1097/DSS.0000000000004472. Online ahead of print.

ABSTRACT

BACKGROUND: One-third of US adults are bothered by excessive sweating, approximately 5% are diagnosed with hyperhidrosis. A topical patch using targeted alkali thermolysis (TAT) was developed for treatment of this condition.

OBJECTIVE: This study was intended to assess the efficacy and safety of the TAT-Patch for axillary sweat reduction.

MATERIALS AND METHODS: A randomized, multicenter, double-blind, sham-controlled, pivotal trial enrolled 120 subjects to a bilateral axillary treatment with a TAT patch (63 subjects) or sham patch (57 subjects).

RESULTS: The primary end point was achieved; 64% of TAT-treated versus 44% of sham-treated subjects (p = .0332) improved from Hyperhidrosis Disease Severity Scale (HDSS) 3/4 to HDDS 1/2 at 4 weeks. Targeted alkali thermolysis treatment also showed a statistically significant improvement over sham treatment for all secondary end points, including gravimetric sweat production and subject-reported quality-of-life (QoL) assessments. The duration of effect is approximately 3 months, determined by the time to return to baseline HDSS. Mild-to-moderate treatment-site adverse events (AEs) were reported in 22% of TAT patch subjects. No serious or severe AEs were reported.

CONCLUSION: HDSS, GSP, and QoL findings confirm clinically meaningful sweat reduction and a significant improvement in quality of life following a single TAT patch treatment. This device has potential to offer a new, noninvasive treatment option that is well tolerated with minimal downtime.

Iontophoresis Improves the Impact on the Quality of Life of Children with Primary Hyperhidrosis-A Prospective Study and a Short Review

Children (Basel). 2024 Oct 17;11(10):1253. doi: 10.3390/children11101253.

ABSTRACT

BACKGROUND: Primary hyperhidrosis (PH) is a somatic and idiopathic pediatric skin disease. The eccrine glands are tiny and very numerous, with approximately 3 million distributed throughout the skin. There is no commonly accepted amount of sweating to define hyperhidrosis, but people with this disease suffer real limitations integrating into society, which can be quantified through quality of life measurement scales. We want to draw attention to this disease and its impact on children’s quality of life because it is significant and there are no studies conducted on groups consisting solely of children.

METHODS: There are various quality of life evaluation questionnaires for hyperhidrosis. We studied 103 children with hyperhidrosis by monitoring their sweat severity and its impact on quality of life, using the Hyperhidrosis Disease Severity Scale. We compared the scale results before and after 10 days of iontophoresis. This study includes only children under 18 years old, treated with iontophoresis.

RESULTS: The average age of the group is 11.84 ± 2.89 years. Treatment success is recorded in 68 (66.02%) children, but a change in the score is recorded in 74 (71.84%) children. The average HDSS score at T0 is 2.95 ± 0.70, compared to the HDSS score at T1 of 1.92 ± 0.86.

CONCLUSIONS: Hyperhidrosis has a negative impact on daily life, especially self-esteem, occupational productivity, emotional well-being, and interpersonal relationships. Iontophoresis is a safe and effective treatment method that reduces the severity of hyperhidrosis and increases the quality of life.

Sexual effects and long-term outcomes of endoscopic lumbar sympathectomy for plantar hyperhidrosis in men: a cross-sectional study

J Vasc Bras. 2024 Sep 27;23:e20240014. doi: 10.1590/1677-5449.202400142. eCollection 2024.

ABSTRACT

BACKGROUND: Plantar hyperhidrosis (PHH) is a disease with high psychosocial impact, and endoscopic lumbar sympathectomy (ELS) has been shown to be the best choice for treatment, but with some concerns such as compensatory sweating (CS) and sexual effects (SE), particularly in men.

OBJECTIVES: The aim of this study is to evaluate the long-term effectiveness of ELS for controlling PHH in men, its side effects, and perceived sexual modifications.

METHODS: A cross-sectional study including only male patients operated for PHH with ELS between 2014-2022 at a private practice. During remote interviews, patients were asked about symptoms before and after ELS and about the postoperative effects on PHH. They were also objectively asked about any SE during the postoperative period. Validated quality of life for hyperhidrosis and erectile function questionnaires were also administered.

RESULTS: 10 male patients averaging 4.26±2.86 years post-ELS were interviewed. Eight of them (80%) achieved complete response (≥80% of sweat reduction) in the first month after surgery and this response was maintained up to the interview date. Two patients had partial response. In six patients, CS occurred, with 5 reporting it as non-troublesome. Six patients reported some type of SE, but none reported erectile dysfunction. Regarding the functional results, all patients rated ELS from good (10%) to very good (30%) or excellent (60%).

CONCLUSIONS: Endoscopic lumbar sympathectomy was effective for treatment of plantar hyperhidrosis in these patients, improving their quality of life and providing lasting PHH control, with some transient sexual dysfunctions that did not impair their sexual life.

Fractional CO(2) Laser-Assisted Delivery of Botulinum Toxin-A Versus Aluminum Chloride in Treatment of Primary Palmar Hyperhidrosis

Photodermatol Photoimmunol Photomed. 2024 Nov;40(6):e13006. doi: 10.1111/phpp.13006.

ABSTRACT

BACKGROUND: Primary palmar hyperhidrosis (PPH) constitutes a distressing dermatologic condition that greatly affects patients’ quality of life. Its management still needs to be addressed to find a suitable therapeutic modality that is readily available, cost effective, and gives patients a quite long disease-free period.

OBJECTIVE: To assess the efficacy of fractional CO2 laser as a delivery method for botulinum toxin-A (BTX-A) and aluminum chloride in treating PPH.

PATIENTS AND METHODS: Twenty-four subjects with PPH were treated on both hands with fractional CO2 laser followed on the right hand with topical BTX-A and on the left hand with topical aluminum chloride. Minor’s starch-iodine test and Hyperhidrosis Disease Severity Scale (HDSS) were used for evaluation of treatment response and for follow-up.

RESULTS: There was a significant improvement in HDSS in both groups, but there was no statistically significant difference in the therapeutic response for both modalities. There was a statistically significant longer disease-free period in the BTX-A-treated hands.

CONCLUSION: Fractional CO2 laser-assisted drug delivery (LADD) represents a safe, minimally invasive procedure that enhances the delivery of BTX-A and aluminum chloride, the two most widely used agents for treating PPH, with a comparable anhidrotic response.

The Influence of the COVID-19 Pandemic on the Addressability to Treatment of Children with Hyperhidrosis-A Retrospective Study and a Short Review

Life (Basel). 2024 Aug 10;14(8):995. doi: 10.3390/life14080995.

ABSTRACT

INTRODUCTION: This study was carried out to demonstrate the negative influence that the COVID-19 pandemic had on the ability of patients to treat hyperhidrosis with iontophoresis. The purpose of this study is to identify the annual distribution of patients with hyperhidrosis as well as elaborate a curve of cases within the time interval studied.

METHODS: It is a retrospective study initiated in the Department of Neuropsychomotor Rehabilitation of the “Sf. Ioan” Emergency Clinical Hospital for Children, Galati, Romania, in which we analyzed the electronic database, the treatment, and the consultation files of all the children who presented between January 2013 and December 2023. We found 111 patients who met the inclusion criteria.

RESULTS: During the 3 years of the pandemic, the number of patients who came to our clinic suddenly dropped to 0.

LIMITATIONS: This study was conducted on a relatively small number of patients in a Neuropsychomotor Recovery clinic. This study includes only patients with palmar and/or plantar hyperhidrosis who presented to the clinic for iontophoresis.

CONCLUSION: Although it is a disease that significantly influences the quality of life, patients and their families do not consider hyperhidrosis to be an urgent problem that can be improved by treatment.

Risk Factors Affecting the Outcomes of CT-Guided Radiofrequency Thermocoagulation of the T3 Sympathetic Nerve in the Treatment of Craniofacial Hyperhidrosis

Ther Clin Risk Manag. 2024 Aug 5;20:465-472. doi: 10.2147/TCRM.S463025. eCollection 2024.

ABSTRACT

BACKGROUND: Current studies mostly suggest that hyperhidrosis is caused by relative sympathetic hyperactivity. Sympathetic radiofrequency thermocoagulation is widely used in clinics. Previous studies have demonstrated that surgery at T3 is effective and safe compared with higher levels, so craniofacial hyperhidrosis in our hospital is selected to be treated at T3. However, some patients pursue repeat medical treatment due to an increase in hyperhidrosis at the original site after surgery. Previous studies have demonstrated the significance of Perfusion index (PI) value in the recurrence of palmar hyperhidrosis, but there is no relevant study on craniofacial hyperhidrosis.

METHODS: Clinical data from patients with craniofacial hyperhidrosis, who underwent T3 sympathetic radiofrequency thermocoagulation at Jiaxing First Hospital (Jiaxing, China) between January 1, 2018 and December 31, 2021, were analyzed. Recurrence in patients 1 year after surgery was recorded through a case search and telephone follow-up system that registered patient information. Clinical data were analyzed using binary logistic regression analysis to investigate risk factors associated with recurrence in patients with craniofacial hyperhidrosis 1 year after surgery.

RESULTS: Of 83 patients included in the present study, 34 (40%) experienced increased craniofacial sweating 1 year after surgery. Results of univariate logistic regression analysis revealed that computed tomography (CT) scan count, increase in pulse index (PI) at the fingertips, and differences in forehead temperature were potential risk factors for postoperative recurrence in patients with craniofacial hyperhidrosis (p<0.2), and the results were consistent on both sides. Three potential risk factors were included in the multivariate logistic regression analysis and results revealed that the risk for recurrence was reduced by 48% (left side) and 67% (right side) for every 1 unit increase in PI value.

CONCLUSION: A small increase in PI was an independent risk factor for recurrence of hyperhidrosis in patients with craniofacial hyperhidrosis after undergoing T3 sympathetic radiofrequency thermocoagulation.

Comparison of Microwave-Based Therapy and Negative-Pressure Suction-Curettage for Axillary Hyperhidrosis and Bromhidrosis: A Retrospective Analysis

Ann Plast Surg. 2024 Aug 1;93(2S Suppl 1):S86-S88. doi: 10.1097/SAP.0000000000003929.

ABSTRACT

BACKGROUND: Axillary hyperhidrosis and bromhidrosis are common clinical diseases, affecting the patients’ work and life. Negative-pressure suction-curettage is the most popular treatment now, but challenged by a new microwave-based therapy (MiraDry). We intend to compare the safety and efficiency of the 2 treatments.

METHODS: A retrospective analysis of 39 female patients with both primary hyperhidrosis and bromhidrosis was conducted. Seventeen patients were treated with MiraDry, and 22 underwent negative-pressure suction-curettage. The postoperative follow-up program included sweat and odor assessments, satisfaction measurement, safety evaluation, and recurrence assessment at different time points until 12 months.

RESULTS: Both treatments showed a significant reduction (P < 0.05) in HDSS score and odor level at 6 and 12 months compared with the baseline. No significant difference in relative reduction was observed between the 2 groups. The satisfaction score of the microwave-based therapy group was higher than that of the negative-pressure suction-curettage group, but no statistical difference was found. The difference in the recurrence rate and complication rate between the groups did not reach significance.

CONCLUSIONS: Microwave-based therapy is a noninvasive treatment with durable effects, low risks, shorter downtime, good appearance, and high satisfaction for axillary hyperhidrosis and bromhidrosis.
