Abstract
Hyperhidrosis is associated with social and emotional stress, affecting quality of life. Microwave energy technology treats primary axillary hyperhidrosis by thermolysis of sweat glands. The successful reduction of sweating in patients with primary axillary hyperhidrosis after microwave treatment has been studied, but there is limited evidence on the psychological and long-term effects. This study examined patient- reported outcome measures including depression and anxiety in patients with primary axillary hyperhidrosis and the effect of microwave therapy on these parameters. Patients received 1 or 2 microwave-based treatments, within 3-month intervals. All patients were finally examined at approximately 1 year after the first treatment using the Hyperhidrosis Disease Severity Scale, Hyperhidrosis Quality of Life©, Dermatology Life Quality Index, and Hospital Anxiety and Depression Scale©. A total of 103 individuals with primary axillary hyperhidrosis were included in the study, with a Hyperhidrosis Disease Severity Scale score of 3 or 4. Statistically significant improvement in quality of life, anxiety, and depression scores were observed at 1-year follow-up. The primary endpoint, Hyperhidrosis Disease Severity Scale of 2 or less 1 year after the first treatment, was achieved by 88.2% of patients. No serious adverse side effects were observed.

Biopsychosoc Med 2024; 18:14. [PMID: 38835082 DOI: 10.1186/s13030-024-00310-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 05/24/2024] [Indexed: 06/06/2024] Open
Abstract
BACKGROUND Patients with primary focal hyperhidrosis (hyperhidrosis) are known to have higher levels of anxiety induced by sweating than those who do not. However, in hyperhidrosis, no scale has been developed to measure anxiety specific to hyperhidrosis symptoms. Therefore, this study aimed to develop an anxiety scale specific to hyperhidrosis symptoms (ASSHS) and to verify its reliability and validity. METHODS Based on previous studies on hyperhidrosis and a preliminary survey conducted with 26 university students who met the diagnostic criteria for hyperhidrosis, 40 items that adequately reflected anxiety specific to hyperhidrosis symptoms were obtained. A survey was done to examine the internal consistency and validity of the our developed ASSHS. In total, 1,207 participants (680 male and 527 female; mean age ± standard deviation 18.7 ± 0.9 years) were included. A second survey (re-survey) was conducted three weeks later to verify the reliability. It included 201 participants (85 male and 116 female; mean age ± standard deviation 18.6 ± 0.7 years). The survey items included (1) the diagnostic criteria for hyperhidrosis, (2) our anxiety scale developed for primary focal hyperhidrosis symptoms (ASSHS), (3) Hyperhidrosis Disease Severity Scale (HDSS), (4) State-Trait Anxiety Inventory (STAI), (5) Hospital Anxiety and Depression Scale (HADS), (6) Dermatology Life Quality Index (DLQI), and (7) presence of anxiety induced by sweating. RESULTS The results of the factor analysis revealed 10 items with one factor, "anxiety specific to hyperhidrosis symptoms." The alpha coefficient of the ASSHS was α = 0.94. The correlation coefficient between the scores at re-test was r = 0.75. A moderate positive correlation was found between the ASSHS, HDSS (r = 0.53), and anxiety induced by sweating (r = 0.47) (all p < 0.001). Additionally, participants with hyperhidrosis symptoms had significantly higher ASSHS scores than did those without hyperhidrosis symptoms (p < 0.001). Those with mild/moderate hyperhidrosis and those with severe hyperhidrosis had significantly higher the ASSHS scores than did those without hyperhidrosis (p < 0.001). CONCLUSIONS This scale has sufficient reliability and validity as an instrument to measure anxiety specific to hyperhidrosis symptoms.

Abstract
In this report, we present the case of a 20-year-old male with childhood-onset hyperhidrosis affecting his fingers and palm flexor surfaces. Dermatological examination revealed café-au-lait macules, palm and sole involvement, and axillary freckling. A starch-iodine test confirmed localized sweating. Neuroimaging identified neurofibromatosis type 1 (NF1) with subcutaneous nodules and dural ectasia in the thoracic spine. The patient was diagnosed with hyperhidrosis and NF1 based on diagnostic criteria, and he responded well to 20% aluminum chloride for treatment of hyperhidrosis. This case represents a unique occurrence of hyperhidrosis with NF1 in Saudi Arabia. Comprehensive evaluation, including systemic assessment, radiology, and starch-iodine testing, aids in diagnosis and understanding of the underlying mechanisms of this disorder, which remains unexplained.

Abstract
Primary hyperhidrosis (PH) is a relatively common chronic disorder, characterized by significant and uncontrollable sweating. The predominant areas of occurrence are hands, feet, head and armpits, and it affects both men and women equally, with a false impression of increased prevalence in women. This study aims to determine the incidence of cases of hyperhidrosis, the gender of the patients and the environment of origin and to identify the most affected age groups and the distribution of hyperhidrosis, as well as creating a curve of cases within the time interval studied and their comparison with those in the specialized literature.

Abstract
Background Primary hyperhidrosis consists of excessive focal sweating. Affected individuals camouflage the sweating on their body, avoiding stigmatisation. Hence, misrepresentation in social interactions is a common feature in patients with hyperhidrosis. The aim of this study was to investigate impostor phenomenon, perfectionism, self-compassion, stress and anxiety among individuals with primary hyperhidrosis. Methods A cross-sectional study was conducted at our clinic among 100 participants with axillary and palmar primary hyperhidrosis. The questionnaire contained a hyperhidrosis part and Perceived Stress Scale-4, Generalised Anxiety Disorder Scale-2, Clinical Perfectionism Questionnaire-6, Self-Compassion Scale Short form and Clance Impostor Phenomenon Scale. Descriptive statistics was used for analyses of categorical variables. As data were normally distributed independent t-test and one-way analysis of variance with post hoc Tukey test were used to compare the mean values for the questionnaires with other variables. Pearson's correlation was used, and a forward multiple linear regression model was performed to predict presence of impostor phenomenon with gender, age and other scales in this study. Results Impostor phenomenon occurred in almost half of our patients (48%) with hyperhidrosis. While feelings of impostor phenomenon were more common in women, there was no difference between gender regarding its intensity levels (p = 0.07). In addition, we found a significant (p < 0.001) negative correlation between impostor phenomenon and self-compassion, while feelings of impostoer phenomenon increased with stress, anxiety and perfectionism (p < 0.001). Conclusions Feelings of impostor phenomenon was found in 48% of individuals with hyperhidrosis which indicates that it is a common feature in this patient group. Future research is warranted regarding the prevalence of impostor phenomenon in hyperhidrosis and other medical conditions, among men and women, seeking medical healthcare. Psychological interventions in hyperhidrosis may be beneficial both for the individual and in public health, by facilitating management of patients' daily lives and saving considerable resources in healthcare regarding pharmacological interventions and medical consultations.

Abstract
Background Primary palmar hyperhidrosis causes a lot of problems for patients and negatively affects their quality of life. Currently, iontophoresis with tap water and aluminum chloride hexahydrate is used for primary palmar hyperhidrosis. Yet, little evidence exists about iontophoresis with aluminum chloride hexahydrate in the form of gel. This study investigated the effect of aluminum chloride hexahydrate gel iontophoresis compared to tap water iontophoresis on primary palmar hyperhidrosis. Methods In this randomised controlled trial study, 32 patients with primary palmar hyperhidrosis were divided randomly into two groups (n = 16). Participants received 7 sessions of iontophoresis with aluminum chloride hexahydrate gel or tap water every other day on the dominant hand. The sweating rate was measured by gravimetry and iodine-starch tests before and after the last treatment session. Results Following the iontophoresis, the rate of sweating in both hands in the two groups was significantly reduced (P < 0.001). However, the sweating rate in the treated hand and the non-treated hand showed no significant difference. There was no significant difference observed in sweating rate reduction between both groups over time, but the larger effect size values observed in the aluminum chloride hexahydrate gel iontophoresis group may suggest the superiority of this gel over tap water in reducing the rate of sweating. Limitations Further investigations with longer follow-up are needed to confirm the hypothesis regarding the effectiveness of aluminum chloride hexahydrate gel iontophoresis over other types of iontophoresis. In addition, contraindications of iontophoresis such as pregnancy, pacemakers, and epilepsy should be considered. Conclusion The present study provides preliminary evidence suggesting that aluminum chloride hexahydrate gel iontophoresis is an effective alternative treatment to decrease sweating rate in extended areas with fewer side effects in patients with primary palmar hyperhidrosis.

Abstract
BACKGROUND In Asia, axillary hyperhidrosis is a frequent problem for many people, and the consequent excessive sweating can seriously affect many aspects of daily life and even lead to mental disorders. Microwave therapy is a new, non-invasive treatment method for axillary hyperhidrosis, whose energy and long-term effectiveness still needs to be clinically validated. OBJECTIVE The aim of this study was to evaluate the clinical efficacy, safety, histological changes, and psychological status of microwave devices in the treatment of axillary hyperhidrosis and osmidrosis. METHOD We conducted a prospective self-controlled study in a top-tier Chinese hospital. After a 5/5 energy treatment session, a skin biopsy was taken to observe histological changes both before and after treatment. An iodine starch test was used to determine the sweating range. We evaluated symptoms of improved efficacy using the Hyperhidrosis Disease Severity Scale (HDSS) and assessed changes in life status with the DLQI. In the case of concurrent underarm odor, odor-5, VAS, and Young-Jin Park grading were used to assess odor relief. The effect of odor on psychology was assessed by using a psychological status symptom checklist (scl-90). The study period was 1 year. RESULTS We observed 20 patients in this study. Of those, 90% met the primary treatment endpoint of a decrease in axillary hyperhidrosis symptomatology to below grade 2 on the HDSS score (p < 0.001). Furthermore, 75% of patients achieved a treatment endpoint of at least 50% reduction in VAS (p < 0.001). 70% of patients achieved a treatment endpoint of at least 50% reduction in odor-5 (p < 0.001). The iodine starch test showed that the region decreased 99% from the baseline to 12 months after follow-up had ended (p < 0.001). Eight patients volunteered to undergo histological examination; their average light density of immunohistochemistry decreased from 1.04 (0.4-2.11) to 0.07 (0.04-0.46; p < 0.05). The immunohistochemical positive number for sweat glands was initially 104 (59.75-132.5) but was 41.5 (29.75-62) after the procedure. None of the patients experienced any serious adverse reactions. CONCLUSION The treatment demonstrated high effectiveness, safety, and short-lived adverse reactions.

Abstract
The use of reconstituted and frozen left-over botulinum toxin A, for treatment of patients with axillary hyperhidrosis seems to be common practice in healthcare. Thus, the objective of this study was to investigate the efficacy and safety of frozen and thawed versus fresh reconstituted abobotulinum toxin (Dysport®) and onabotulinum toxin (Botox®) in the treatment of axillary hyperhidrosis. A retrospective study was conducted analysing efficacy and data from pre- and 24 weeks post-treatment questionnaires together with medical records of individuals with moderate to severe axillary hyperhidrosis. The patients had received fresh prepared botulinum toxin A in their right axilla while frozen and thawed botulinum toxin A had been administered in their left axilla. Treatment was conducted at our Hyperhidrosis Clinic, Umeå University Hospital, Sweden 2019-2021. Pre- and post-treatment questionnaires from 106 patients were analysed. The patients were 18 to 55 years old, with a mean age of 30.7 ± 9.9 years. No significant differences in patient-reported variables, Hyperhidrosis Disease Severity Scale and VAS 10-point scale, were found between the different preparations (frozen compared to fresh) for abobotulinum toxin and onabotulinum toxin, before treatment and at 6 months follow-up. Multivariable regression analysis resulted in no significant difference regarding side-effects between the preparations or brands of botulinum toxin. The findings of this study support our clinical experience that both abobotulinum toxin and onabotulinum toxin, reconstituted, frozen and thawed, seem to be as effective and safe as fresh prepared botulinum toxin when treating axillary hyperhidrosis. Our findings indicate that left-over preparations of abo- and onabotulinum toxins, stored and frozen for up to 6 months, is a cost-and time-effective way of handling botulinum toxin for treatment of axillary hyperhidrosis.

Abstract
PURPOSE The aim of this study was to investigate the success rate of surgical technique and associated risk factors based on the follow-up of patients who underwent CT-guided percutaneous radiofrequency sympathectomy (RFS) to treat primary hyperhidrosis (PH). METHODS 370 patients who underwent RFS for PH treatment between January 2018 and April 2022 were enrolled. Patients responded to a questionnaire and telephone follow-up on the effects of treatment and their electronic medical records and imaging findings were reviewed. Logistic regression was performed to identify risk factors related to the success rate of surgical technique. RESULTS A temperature difference ≥2 °C before and after procedure was defined as a successful surgical technique. Among the 370 patients (740 sides), 637 sides had successful RFS, and the technical success rate was 86.1 %. Immediately after procedure, 636 sides (85.9 %) were completely dry, 64 (8.7 %) were partially dry, and 40 (5.4 %) were still wet. During the longest follow-up period (54 months), 103 patients relapsed. The median hyperhidrosis disease severity scale score on both sides decreased from 4 to 1 after RFS. According to logistic regression analysis, only the pre-post pulse index was associated with the success rate of surgical technique (odds ratio, 1.14; 95 % confidence interval, 1.06-1.23; p = 0.0004). CONCLUSIONS We observed that the immediate efficiency and success rate of surgical technique after RFS for PH treatment were relatively high, although there is a possibility of recurrence in the long term. In general, RFS is a safe and effective procedure for alleviating the symptoms of patients with hyperhidrosis.

Abstract
BACKGROUND Primary focal hyperhidrosis (PH) can be managed by a wide range of medical and surgical modalities. Compensatory hyperhidrosis (CH) is a well-documented complication of surgical treatment. We aimed to investigate the occurrence of compensatory hyperhidrosis (CH) in PH patients after nonsurgical treatment with botulinum toxin A (BTX- A) or iontophoresis. METHODOLOGY We carried out a unicentric prospective study on PH patients from King Abdullah University Hospital (KAUH) in Jordan. PH patients were evaluated after 1-month of nonsurgical treatment. Patients who developed CH were re-assessed after 3-6 months through a telephone-based interview. RESULTS A total of 86 patients with PH who underwent nonsurgical treatment with iontophoresis or botulinum toxin were recruited. Twenty-four (27.9%) patients developed subjective CH. It was mild in (75%), moderate in (21%), and severe in (4%) of patients affected, it was self-limiting within a few months in all patients. Patients with CH did not differ significantly in demographic or clinical variables from patients who did not develop CH except at the site of PH (p value = .05). CONCLUSION The findings of this study indicate that more than quarter (27.9%) of patients with PH may develop minor compensatory sweating, however this didn't affect satisfaction with treatment.

Abstract
PURPOSE To evaluate the recurrence rate of primary hyperhidrosis (PH) after computed tomography (CT)-guided radiofrequency sympathectomy (RFS) and identify risk factors associated with recurrence. MATERIALS AND METHODS A total of 290 patients with PH who underwent CT-guided RFS were included in this retrospective cohort study. The electronic medical record was reviewed for patients' information and procedural parameters. Follow-ups were conducted for recurrence rate, and Hyperhidrosis Disease Severity Scale was used to assess presence or absence of recurrence. Stepwise regression and the least absolute shrinkage and selection operator regression algorithms were used for feature selection. RESULTS The recurrence rate 1 year after procedure was 17.6%. Male (hazard ratio [HR], 2.35; 95% confidence interval [CI], 1.08-5.15), low postoperative palm or foot temperature (HR, 0.77; 95% CI, 0.60-0.98), high postoperative heart rate (HR, 1.06; 95% CI, 1.02-1.10), low preoperative and postoperative hospital anxiety and depression score difference (HR, 0.59; 95% CI, 0.43-0.80), and the absence of compensatory hyperhidrosis immediately after procedure (HR, 0.46; 95% CI, 0.22-0.98) were established as independent factors affecting prognosis. A nomogram was built accordingly. The C indices of the training and testing sets were 0.773 and 0.659, respectively. CONCLUSIONS Follow-up results showed that the recurrence rate of PH treated with CT-guided RFS was low. This study constructed and validated a nomogram to predict the recurrence of PH 1 year after CT-guided RFS, which is convenient for interventionalists to evaluate accurately the prognosis of patients postoperatively and to identify high-risk patients who need more active treatment.

Long-term evaluation of the safety and efficacy of a novel 20% oxybutynin hydrochloride lotion for primary palmar hyperhidrosis: An open-label extension study. J Dermatol 2023; 50:1459-1472. [PMID: 37605375 DOI: 10.1111/1346-8138.16922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/19/2023] [Accepted: 07/28/2023] [Indexed: 08/23/2023]
Abstract
The long-term safety and efficacy of 52-week application of oxybutynin hydrochloride 20% lotion (20% OL) for the treatment of primary palmar hyperhidrosis (PPHH) in Japanese patients aged ≥12 years were evaluated in an open-label extension (OLE) of a 4-week, randomized, double-blind (DB) study. The OLE included 114 patients who completed the DB study and wished to continue treatment and 12 new patients. In the safety analysis population (125 patients), the incidence of adverse events (AEs) and adverse drug reactions (ADRs) was 79.2% and 36.0%, respectively. Serious AEs were observed in two patients but were considered unrelated to the investigational drug. The incidence of AEs that led to study discontinuation was 1.6%. The incidence of application site AEs and ADRs was 35.2% and 26.4%, respectively. The severity of most events was mild. The incidence of anticholinergic AEs related to dry mouth was 3.2% for thirst and 0.8% for dry throat. The long-term efficacy of 20% OL was confirmed by a long-lasting reduction in sweat volume and improvement in the Hyperhidrosis Disease Severity Scale and Dermatology Life Quality Index. This study has several limitations: First the results may include some bias because most of the participants were from the prior DB study; second, the results may not be generalizable because only a few participants were in the age group most susceptible to PPHH (i.e., < 15 years old); and third, the study did not obtain safety information from treatment for more than 52 weeks, so this information must be collected in clinical practice in the future. No reduced therapeutic effect was observed in patients with PPHH in this study after 52-week application of 20% OL. Also, few patients experienced serious AEs or AEs that led to study treatment discontinuation.

Abstract
BACKGROUND Sweating is a physiologic mechanism of human thermoregulation. Hyperhidrosis is defined as a somatic disorder where the sweating is exaggerated in an exact area because the sweat glands are hyperfunctioning. It negatively affects the quality of life of the patients. We aim to investigate patient satisfaction and the effectiveness of oxybutynin in treating hyperhidrosis. METHODS We prospectively registered the protocol of this systematic review and meta-analysis on PROSPERO (CRD 42022342667). This systematic review and meta-analysis were reported according to the PRISMA statement guidelines. We searched three electronic databases (PubMed, Scopus, Web of Science) from inception until June 2, 2022, using MeSH terms. We include studies comparing patients with hyperhidrosis who received oxybutynin or a placebo. We assessed the risk of bias using the Cochrane risk of bias assessment tool (ROB2) for randomized controlled trials. The risk ratio was calculated for categorical variables, and the mean difference was calculated for continuous variables using the random effect model with 95% confidence intervals (CI). RESULTS Six studies were included in the meta-analysis, with a total of 293 patients. In all studies, patients were assigned to receive either Oxybutynin or Placebo. Oxybutynin represented an HDSS improvement (RR = 1.68 95% CI [1.21, 2.33], p = 0.002). It also can improve the quality of life. There is no difference between oxybutynin and placebo regarding dry mouth (RR = 1.68 95% CI [1.21, 2.33], p = 0.002). CONCLUSION Our study suggests that using oxybutynin as a treatment for hyperhidrosis is significant and needs to be highlighted for clinicians. However, more clinical trials are needed to grasp the optimum benefit.

Abstract
BACKGROUND The most important problem with local injections of botulinum toxin type A (BTX-A) in palmar hyperhidrosis is pain during the injections. OBJECTIVES We evaluated therapeutic effectiveness and pain of local injections of BTX-A using needle-free direct administration system. METHODS We performed BTX-A local injection therapy using a conventional injection needle in the left hand and a needle-free direct administration system in the right hand. RESULTS A reduction in the quantity of perspiration was observed 4 weeks after administration of both Needle and Needle-free BTX-A, and reduction was maintained throughout 28 weeks observation period. Both hyperhidrosis Disease Severity Scale scores and Dermatology Life Quality Index for hands treated with Needle BTX-A and hands treated with Needle-free BTX-A had decreased significantly by 4 weeks after treatment. Pain visual analog scale scores and the degree of pain were significantly lower in hands treated with Needle-free BTX-A than in hands treated with Needle BTX-A. CONCLUSIONS When the trigger of the pressurized needle-free injector device is activated, the gas powered driving pressure propels BTX-A through an orifice (0.13 mm) about four times narrower than a 30 G needle at very high speed. As most pain occurs during the needle prick itself, the advantage of a small orifice coupled with high-speed penetration of BTX-A through the pressurized device results in reduced pain during administration. The needle-free direct administration system administers the injectate under the skin without a visible needle.

Abstract
PURPOSE Hyperhidrosis can be a debilitating disease that leads to the deterioration of well-being. In this study, the objective was to compare the health-related quality of life (HRQOL) in individuals with and without hyperhidrosis by conducting a systematic review and meta-analysis. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Meta-analysis Of Observational Studies in Epidemiology checklist were employed. We systematically searched Cochrane Library, Embase and PubMed. Two authors independently assessed the literature and extracted the data. The risk of bias was assessed using the Newcastle-Ottawa Scale. A random-effects model was employed. The heterogeneity was determined using I2. RESULTS Eleven studies met the eligibility criteria comprising 4297 and 147,604 participants with and without hyperhidrosis, respectively. The risk of bias ranged from high quality to very high risk of bias. The individuals with hyperhidrosis had a higher Dermatology Life Quality Index (mean difference 8.53; 95% confidence interval 3.47, 13.58; p = 0.0009) and a lower mental component summary of the short form-12 or -36 (mean difference -6.15; 95% confidence interval -9.00, -3.30; p < 0.0001) than the control individuals. No difference was found for the physical component summary score of the short form-12 or -36 (mean difference -0.88; 95% confidence interval -1.88, 0.12; p = 0.085). Studies using patient-reported outcomes, not included in the meta-analysis, showed similar results. CONCLUSION Individuals with hyperhidrosis experience a reduced HRQOL that is clinically meaningful and leads to perceivable deteriorations in their well-being. The evidence shows a high degree of heterogeneity, which warrants additional studies.

Abstract
Hyperhidrosis (chronic excessive sweating) may substantially affect an individual's emotional and social well-being. Therapies available before onabotulinumtoxinA were generally topical, with limited effectiveness, application-site skin reactions, and frequent, time-consuming treatments. Intradermal injection of onabotulinumtoxinA to treat sweat glands arose as a novel therapeutic approach. To develop this treatment, appropriate dosing needed to be established, and training on administration was required. Further, no previous scale existed to measure the effects of hyperhidrosis on patients' lives, leading Allergan to develop and validate the 4-point Hyperhidrosis Disease Severity Scale (HDSS), which measures the disease's impact on daily activities. The onabotulinumtoxinA clinical development program for hyperhidrosis included 2 double-blind, placebo-controlled pivotal trials, immunogenicity studies, long-term studies of safety and efficacy, and quality of life assessments. In Europe and North America, the primary efficacy measures were, respectively, axillary sweat production measured gravimetrically and HDSS improvement. Compared with placebo, onabotulinumtoxinA treatment significantly reduced axillary sweat production and axillary hyperhidrosis severity, as measured by a 2-point or greater reduction on the HDSS. The effects of onabotulinumtoxinA occurred rapidly, within 1 week after injection, and lasted ≥6 months. Treatment with onabotulinumtoxinA was associated with significant quality of life improvements based on Short Form-12 physical and mental component scores. The Hyperhidrosis Impact Questionnaire also indicated greater treatment satisfaction, reduced negative impact on aspects of daily life, and improved emotional well-being with onabotulinumtoxinA versus placebo. The clinical development program and subsequent clinical experience showed that onabotulinumtoxinA treatment for hyperhidrosis was well tolerated with no new safety signals, and led to greater disease awareness.

Abstract
BACKGROUND No previous controlled studies have been specifically designed or adequately powered to show the efficacy of topical oxybutynin for palmar hyperhidrosis by using quantitative measures. OBJECTIVE To evaluate efficacy of 20% oxybutynin hydrochloride lotion (20% OL) in reducing palmar sweat volume in patients with primary palmar hyperhidrosis (PPHH). METHODS In a randomized controlled trial, Japanese patients with PPHH aged 12 years and older received either 20% OL (n = 144) or placebo (n = 140) on both palms once daily for 4 weeks. Palmar sweat volume was measured by the ventilated capsule method. For the primary outcome, response was defined as a reduction of sweat volume of at least 50% from baseline. RESULTS At week 4, the responder rate for sweat volume was significantly higher in the 20% OL arm than in the placebo arm (52.8% vs 24.3%, respectively; treatment difference, 28.5% [95% CI, 17.7% to 39.3%]; P < .001). No serious adverse events occurred, and no adverse events led to treatment discontinuation. LIMITATIONS The treatment period was only 4 weeks. CONCLUSIONS In patients with PPHH, 20% OL is superior to placebo in reducing palmar sweat volume.

Abstract
Background Primary palmar hyperhidrosis (PPH) is a condition marked by an overactive secretion of the hand's exocrine glands and is frequently hereditary. The profuse sweating associated with this condition can significantly impair the patient's daily activities and quality of life. Objective The objective of this study was to compared the benefits and drawbacks of thoracic sympathetic block and thoracic sympathetic radiofrequency in the treatment of PPH. Methods A retrospective analysis was conducted on 69 patients. They were divided into groups A and B according to their treatment. Group A (34 cases) received CT-guided percutaneous thoracic sympathetic nerve chain anhydrous alcohol chemical damage block, and group B (35 cases) received CT-guided percutaneous thoracic sympathetic nerve chain radiofrequency thermocoagulation. Results Palmar sweating disappeared immediately after the operation. The recurrence rates at 1, 3, 6, 12, 24, and 36 months were 5.88% vs. 2.86% (P > 0.05), 20.59% vs. 5.71% (P > 0.05), 32.35% vs. 11.43% (P < 0.05),32.35% vs. 11.43% (P < 0.05), 25% vs. 14.71% (P < 0.05), and 68.75% vs. 20.59% (P < 0.05), respectively. The incidence of intercostal neuralgia and compensatory hyperhidrosis was higher in group A compared with of group B (52.94% vs. 22.86%, P < 0.05; 55.88% vs. 22.86%, P < 0.05). Conclusion Both methods were found to be effective in treating PPH, but thoracic sympathetic radiofrequency had a longer-term effect, a lower recurrence rate, and a lower incidence of intercostal neuralgia and compensatory hyperhidrosis than a thoracic sympathetic block.

Abstract
To obtain current epidemiological information on primary focal hyperhidrosis in Japan, a large epidemiological survey was conducted using a web-based questionnaire. The prevalence of primary focal hyperhidrosis was 10.0% and the site-specific prevalence was highest for primary axillary hyperhidrosis (5.9%). The proportion of respondents with primary focal hyperhidrosis who had consulted a physician was 4.6%, which was similar to the low prevalence reported previously in 2013 in Japan. A questionnaire survey for physicians and individuals with primary axillary hyperhidrosis on the current medical management of primary axillary hyperhidrosis showed that physicians recognized the existence of patients who were very worried about hyperhidrosis, but failed to provide active treatment. Regarding the information provided by patients to physicians at presentation, it was found that patients failed to provide sufficient information to the physicians about their worries in daily life. Among individuals who had sought medical care with primary axillary hyperhidrosis, 62.3% reported that they were not currently receiving treatment, highlighting a challenge to be addressed regarding continued treatment. Frequently chosen options leading to willingness to receive treatment were less expensive treatment and highly effective treatment as well as feeling free to consult a physician, suggesting a desire for an improved medical environment.

Abstract
Hyperhidrosis significantly reduces patients' quality of life, with many reporting feeling highly anxious. However, the relationship between hyperhidrosis and anxiety induced by sweating has not been examined in detail. The current study examined the relationship between: (1) the presence of hyperhidrosis symptoms, (2) hyperhidrosis severity, and (3) the sites of the most sweating and anxiety induced by sweating. A cross-sectional web-based survey was conducted among university students, and 1080 consenting participants (600 males and 480 females; mean age, 18.8 years) were included in the analysis. The survey items were: (1) diagnostic criteria for hyperhidrosis, (2) Hyperhidrosis Disease Severity Scale, (3) presence of anxiety induced by sweating, and (4) site of the most sweating. The results of multiple logistic regression analysis adjusted for sex and age showed that the odds ratio (OR) for anxiety induced by sweating was significantly higher in participants who screened positive for hyperhidrosis than in those who screened negative (OR, 9.72 [95% CI, 5.80-16.27]). The OR of anxiety induced by sweating was 7.11 (95% CI, 3.99-12.65) for mild/moderate hyperhidrosis and 23.46 (95% CI, 7.15-76.93) for severe hyperhidrosis, compared with those who screened negative for hyperhidrosis. Compared with those who screened negative for hyperhidrosis, the OR for anxiety induced by sweating in those with the palmar, plantar, axillary, and head/face as the site of the most sweating was 7.74 (95% CI, 3.91-15.33), 14.86 (95% CI, 1.83-120.58), 16.92 (95% CI, 5.95-48.14), and 5.38 (95% CI, 1.39-20.74), respectively. Our findings suggest that participants who screened positive for hyperhidrosis, mild/moderate or severe, are at a higher risk of anxiety induced by sweating than participants who screened negative for hyperhidrosis.

Abstract
Background: Identification of underlying diseases is crucial for secondary hyperhidrosis management, but data are lacking to guide appropriate investigation.Objective: To describe aetiologies of recurrent sweating in a hospital setting and the diagnostic performance parameters of their respective clinical/biological features.Patients and Methods: We performed a monocentric evaluative study in a tertiary care centre. Patients with recurrent generalised sweating were selected via the Clinical Data Warehouse (CDW) by screening all electronic hospital documents from the year 2018 using a keyword-based algorithm. All in and out-patients aged ≥ 18 years having reported recurrent sweating for at least 2 weeks in 2018 were included, with a minimum one-year follow-up after symptoms' onset.Results: A total of 420 patients were included. Over 130 different aetiologies were identified; 70 patients (16.7%) remained without diagnosis. Solid organ cancers (14.3% with 13 lung cancers), haematologic malignancies (14.0% with 35 non-Hodgkin's lymphomas) and Infectious Diseases (10.5% including 13 tuberculosis) were the most frequent diagnoses. Other aetiologies were gathered into inflammatory (16.9%) and non-inflammatory (27.6%) conditions. To distinguish non-inflammatory and undiagnosed hyperhidrosis from other causes, fever had a specificity of 94%, impaired general condition a sensitivity of 78%, and C-reactive protein (CRP) > 5.6 mg/l a positive predictive value of 0.86. Symptoms' duration over 1 year was in favour of non-infectious and non-malignant causes (94% specificity).Conclusions: We identified fever, impaired general condition, duration, and CRP as helpful orientation parameters to assess the need for complementary explorations for hyperhidrosis. The study provides a diagnostic algorithm for the investigation of recurrent sweating.KEY MESSAGESIn a hospital setting, malignancies and infections are the most frequently associated diseases, but 1/5 remain without diagnosis.Fever is a specific but not sensitive sign to distinguish inflammatory conditions.Over 1 year duration of symptoms significantly reduce the probability of malignancy or infection as the underlying diagnosis.

Abstract
BACKGROUND Research on hyperhidrosis comorbidities has documented the co-occurrence of diseases but has not provided information about temporal disease associations. OBJECTIVE To investigate the temporal disease trajectories of individuals with hospital-diagnosed hyperhidrosis. METHODS This is a hospital-based nationwide cohort study including all patients with a hospital contact in Denmark between 1994 and 2018. International Classification of Diseases version-10 diagnoses assigned to inpatients, outpatients and emergency department patients were collected from the Danish National Patient Register. The main outcome was the temporal disease associations occurring in individuals with hyperhidrosis, which was assessed by identifying morbidities significantly associated with hyperhidrosis and then examining whether there was a significant order of these diagnoses using binomial tests. RESULTS Overall, 7 191 519 patients were included. Of these, 8758 (0.12%) patients had localized hyperhidrosis (5674 female sex [64.8%]; median age at first diagnosis 26.9 [interquartile range 21.3-36.1]) and 1102 (0.015%) generalized hyperhidrosis (606 female sex [59.9%]; median age at first diagnosis 40.9 [interquartile range 26.4-60.7]). The disease trajectories comprised pain complaints, stress, epilepsy, respiratory and psychiatric diseases. The most diagnosed morbidities for localized hyperhidrosis were abdominal pain (relative risk [RR] = 121.75; 95% Confidence Interval [CI] 121.14-122.35; P < 0.001), soft tissue disorders (RR = 151.19; 95% CI 149.58-152.80; P < 0.001) and dorsalgia (RR = 160.15; 95% CI 158.92-161.38; P < 0.001). The most diagnosed morbidities for generalized hyperhidrosis were dorsalgia (RR = 306.59; 95% CI 302.17-311.02; P < 0.001), angina pectoris (RR = 411.69; 95% CI 402.23-421.16; P < 0.001) and depression (RR = 207.92; 95% CI 202.21-213.62; P < 0.001). All these morbidities were diagnosed before hyperhidrosis. CONCLUSIONS This paper ascertains which hospital-diagnosed morbidities precede hospital-diagnosed hyperhidrosis. As hyperhidrosis mainly is treated in the primary health care sector, the trajectories suggests that these morbidities may lead to a worse disease course of hyperhidrosis that necessitates treatment in hospitals. Treating these morbidities may improve the disease course of hyperhidrosis.

Abstract
Hyperhidrosis is a dermatosis presenting as pathologically excessive focal or generalized sweating. The stigmatizing nature of hyperhidrosis may cause patients to feel embarrassment and apprehension about their symptoms and experience a significant decrease in well-being. Severe cases of hyperhidrosis can also increase the risk of developing psychiatric and somatic comorbidities. Conventional non-surgical treatments of hyperhidrosis include aluminum salts, iontophoresis, botulinum toxin injections, and oral glycopyrronium. In recent years, new topical anticholinergic medications and devices have emerged that may improve the patients' symptoms and even prevent the development of comorbidities. The treatment of hyperhidrosis can be a complex matter and may require the combination of several therapies. The purpose of this paper was to firstly review the literature on existing non-surgical treatment options for hyperhidrosis, and secondly provide a stepwise approach to investigating and treating patients with hyperhidrosis.

Abstract
INTRODUCTION Idiopathichyperhidrosis is a dysfunctional disorder involving eccrine sweat glands and its impact on patients' daily quality of life is well-known. Unlike some years ago, when only poor effective and safe therapeutic alternatives were available, nowadays, several emerging pharmacological active substances have gained significant space as treatment options. AREAS COVERED The authors report on, in this narrative review, the emerging data from the literature focusing on the pharmacological treatments to draw up a drug treatments flow-chart for patients with idiopathic hyperhidrosis, taking into consideration specific differences among axillary, palmoplantar and craniofacial hyperhidrosis. EXPERT OPINION Idiopathic hyperhidrosis, regardless of the site of involvement, remains a functional disorder that places a significant burden on patients. After balancing efficacy against adverse events, systemic therapy, although off-label for all forms of hyperhidrosis can represent an additive therapeutic option for patients with insufficient response to topical treatment according to a step wise therapeutic approach. Until the pathophysiological mechanisms underlying hyperhidrosis are clear, and the etiological therapeutic approach become realistic, the greatest challenge in the therapeutic management of hyperhidrotic patients seems to be the search for the most convenient combination between different therapeutic modalities (topical and systemic agents, and botulinum toxins) to achieve long-term control of the disease symptoms.

Abstract
Botulinum toxin (BoNT) is a neurotoxin produced by the Clostridium botulinum bacteria. Among seven different isoforms, only BoNT-A and BoNT-B are commercially used. Currently, botulinum toxin has been indicated by the U.S. Food and Drug Administration in several disorders, among others: chronic migraine, hyperhidrosis, urinary incontinence from detrusor overactivity, or cosmetics. However, there are numerous promising reports based on off-label BTX usage, indicating its potential effectiveness in other diseases, which remains unknown to many. Among them, dermatological conditions, such as rosacea, annal fissure, Raynaud phenomenon, hypertrophic scars and keloids, and also hidradenitis suppurativa, are currently being investigated. This article aims to provide a comprehensive update on the off-label use of botulinum toxin in dermatology, based on an analysis and summary of the published literature.

Abstract
OBJECTIVES Our study examined attitudes towards initial management of hyperhidrosis, willingness to seek surgical consultation and knowledge of an appropriate specialty for surgical consultation among primary care physicians and the general public. METHODS An online survey was sent to all general medicine and paediatric residents and attending physicians at our academic medical centre. Participants were provided with a clinical scenario of palmar hyperhidrosis and were asked to select among initial management options and preferences for surgical consultation if patients failed non-operative management. To assess the general public's perspective, workers from Amazon Mechanical Turk were recruited to complete a similar survey. RESULTS The majority of primary care physicians (31/53; 58%) would prescribe topical aluminium chloride for palmar hyperhidrosis, whereas 28 of 53 (53%) would refer such patients to dermatology. Twenty-three of 53 (43%) physicians would refer such patients to surgery if conservative management failed: 18 (78%) to plastic surgery, 4 (17%) to general surgery and none to thoracic surgery. The majority of workers (130/205; 63.4%) would seek primary care treatment for palmar hyperhidrosis. Over half (113/205; 55%) would seek surgical consultation if conservative management failed: 65 (58%) general surgery and 15 (13%) neurosurgery, with only 8 (7%) selecting thoracic surgery. CONCLUSIONS Neither primary care physicians nor the general public recognize the role of thoracic surgeons in managing primary focal hyperhidrosis when medical management fails. Education of physicians and the public may mitigate this knowledge gap.

Abstract
In 2020, 5% sofpironium bromide (ECCLOCK®) gel (hereinafter referred to as sofpironium) was approved in Japan for the topical treatment of primary axillary hyperhidrosis. A phase III study of sofpironium demonstrated the efficacy and safety of sofpironium; however, no study has assessed its early efficacy at <6 weeks after starting treatment. Therefore, to assess the earlier effectiveness of sofpironium, we conducted a 2‐week, single‐center, exploratory, prospective, observational study in Japanese patients with primary axillary hyperhidrosis. Patients aged ≥20 years and satisfying with a Hyperhidrosis Disease Severity Scale (HDSS) score of 3 or 4 at baseline were eligible for the study. The primary endpoint for the effectiveness was change in the proportion of patients with a HDSS score of 1, 2, 3, or 4 during the 2‐week study period. In 80 patients included in the full analysis set (FAS), there were more women than men (93.8% vs. 6.3%), and the mean age (±standard deviation [SD]) was 33.3 ± 9.4 years. In the FAS, the proportion of patients with a HDSS score of 1 or 2 was 55.0% on day 7, and statistically significant changes were observed after day 3 compared to baseline (p < 0.05). Mean HDSS scores (±SD) were significantly decreased from baseline value of 3.5 ± 0.5 to 2.4 ± 0.9 on day 7 (p < 0.001). The median period for sofpironium treatment to achieve a HDSS score of 1 or 2 for a continuous 2 days was 6 days (95% confidence interval, 4–8). Safety was evaluated in 92 patients in the safety analysis set, and no adverse events were reported during the study period of 2 weeks. These results suggest that after 1‐week treatment with sofpironium for patients with a HDSS score of 3 or 4, approximately 50% of the patients can achieve a HDSS score of 1 or 2, which is a clinically significant improvement for the patients.

Abstract
When the human body is anesthetized, the human nerve tissue will be greatly affected, which also affects the breathing of the human body. The respiration during anesthesia is a lack of initiative, and the energy efficiency of the diaphragm in the lungs is very important to the safety of anesthesia. In this paper, the application of the ultrasound evaluation of the diaphragm in clinical anesthesia was studied. In this paper, 24 patients who underwent lung examination under medical anesthesia at our hospital were evaluated by the ultrasound vertical mixed echo method. Through patient voluntary selection and consent, 16 patients were examined with B-mode ultrasound and the other 8 patients with M-mode ultrasound to compare the effects of different ultrasounds on diaphragm image quality. In addition, this paper also analyzes the differences between different ultrasounds and the strengths and weaknesses of diaphragmatic ultrasound evaluation in clinical anesthesia. The suggestions of using different ultrasounds in ultrasonic evaluation are given. The study showed that 16 cases of B-mode ultrasound evaluation of the diaphragm obtained ultrasound images which showed a large field of vision, acoustic frequency between 7 and 18 MHz, and thickness difference between 0.35 and 0.52 cm. In 8 patients with the diaphragm evaluated by M-mode ultrasound, the local features of M-mode ultrasound images were clearer than those of B-mode ultrasound images, but the visual field area was smaller, the acoustic frequency was between 10 and 15 MHz, and the thickness difference was between 0.12 and 0.18 cm. Based on the above data, this paper suggests that, in the ultrasonic evaluation of the diaphragm, B-mode ultrasound should be used to check the patients first, and then M-mode ultrasound should be used to check the parts with poor quality so that the accurate diaphragm quality of patients can be obtained in the vast majority of patients.

Familial clustering of the skin disease primary hyperhidrosis suggests a genetic component to the disease. The human leucocyte antigen (HLA) is implicated in a range of diseases, including many comorbidities to hyperhidrosis. No study has investigated whether the HLA genes are involved in the pathogenesis of hyperhidrosis. We, therefore, compared HLA alleles in individuals with and without hyperhidrosis in this study of 65,000 blood donors. In this retrospective cohort study, we retrieved information on individuals with and without hyperhidrosis using self-reported questionnaires, the Danish National Patient Registry and the Danish National Prescription Registry on participants recruited to the Danish Blood Donor Study between 2010 and 2019. Association tests using logistic regression were conducted for each HLA allele corrected for sex, age, body mass index, smoking and principal components. Overall, 145 of 65,795 (0.2%) participants had hospital diagnosed hyperhidrosis. Similarly, 1,379 of 15,530 (8.9%) participants had moderate-severe self-reported hyperhidrosis, of whom 447 (2.9%) had severe self-reported hyperhidrosis. Altogether 28 participants had both hospital diagnosed and moderate-severe self-reported hyperhidrosis. Severe self-reported hyperhidrosis was associated with HLA-A*80:01 (adjusted odds ratio 26.97; 95% confidence interval 5.32-136.70; n=7; p<0.001). Moderate-severe self-reported hyperhidrosis and hospital diagnosed hyperhidrosis were not associated with any HLA. The association between hyperhidrosis and HLA-A*80:01 was based on a very small number of cases and not replicated in other patient subsets, and therefore likely a chance finding. Thus, this study suggests that genes other than the HLA are involved in the pathogenesis of hyperhidrosis.

Abstract
Hyperhidrosis, the medical term for excessive sweating beyond physiological need, is a condition with serious emotional and social consequences for affected patients. Symptoms usually appear in focal areas such as the feet, hands, axillae and face. Non-surgical treatment options such as topical antiperspirants or systemic medications are usually offered as a first step of treatment, although these therapies are often ineffective, especially in severe and intolerable cases of hyperhidrosis. In the treatment algorithm for patients suffering from hyperhidrosis, surgical thoracoscopic sympathicotomy offers a permanent solution, which is particularly effective in the treatment of palmar hyperhidrosis and facial blushing. In this review, we describe the current status of thoracoscopic sympathicotomy for palmar hyperhidrosis and facial blushing. In addition, we share the specific treatment approach, technique and results of our Hyperhidrosis Expert Center. Last, we share recommendations to ensure an effective, reproducible and safe application of single-port thoracoscopic sympathicotomy for palmar hyperhidrosis and facial blushing, based on our extensive experience.

Abstract
BACKGROUND Tap water iontophoresis (TWI) is an effective treatment option for palmoplantar hyperhidrosis (HH). However, the optimal number and frequency of TWI sessions to control profuse sweating are unclear. OBJECTIVE To compare the efficacy of 10 and 20 sessions of TWI in patients with palmoplantar HH and determine the adequate number of sessions to achieve a favorable clinical response. METHODS Eighty patients treated with TWI for palmoplantar HH were included. The alteration in sweating intensity considering the mean value of gravimetric measurement and mean visual analog scale (VAS) scores after the 10th and 20th session of TWI were calculated. The difference between performing 10 and 20 sessions of TWI in providing improvement of HH was analyzed. We also conducted a telephone-based inquiry to determine the patients' outcome. RESULTS The reduction in sweating intensity was significant both after the 10th (p < 0.001) and 20th (p < 0.001) sessions when compared with the basal level considering gravimetry and VAS. When the mean sweating intensity after the 10th and 20th sessions were compared, no difference was observed gravimetrically (p = 0.03); the difference between the mean score of VAS after the 10th and 20th sessions (p < 0.001) was significant. Eleven and nine patients not considering a maintenance or an alternative treatment had lower and same sweating intensity as compared with the baseline, respectively. CONCLUSION Ten TWI sessions within two weeks for managing palmoplantar HH are adequate to achieve a clinical response. However, the patients are more satisfied when they receive 20 sessions instead of 10 sessions of TWI.

Abstract
Primary hyperhidrosis (PH) is a disease characterized by focal and excessive sweating.Purpose: The aim of this study was to describe the experiences of men and women with PH when seeking help for their condition.Method: A qualitative interview study with 30 men and women diagnosed with PH was conducted. Data was inductively analysed using manifest and latent content analysis.Results: The analysis resulted in a theme: Navigating in the fog, based on the categories doubtful encounters with health care professionals, helpful encounters with health care professionals, delays due to inadequate knowledge, and supported urge for help.Conclusions: Deficient knowledge and understanding about PH create a sense of resignation in individuals, resulting in delay of seeking treatment. Support from others, life-changing events, and finding information about PH were important motivating factors in seeking help and demanding access to treatment. A holistic approach towards patients with PH is important to reduce stigma and acknowledge the problems that are encountered in their daily lives. Educating health care professionals and students so that patients can be identified and assessed without delay and making information available about PH in schools and pharmacies could improve the general knowledge and facilitate obtaining treatment for individuals with PH.

Abstract
The process of sweating plays an important role in the human body, including thermoregulation and maintenance of the environment and health of the skin. It is known that the conditions of hyperhidrosis and anhidrosis are caused by abnormalities in sweat secretion and can result in severe skin conditions such as pruritus and erythema, which significantly reduce the patient's quality of life. However, there are many aspects of the signaling mechanisms in the process of sweating that have not been clarified, and no effective therapies or therapeutic agents have yet been discovered. Previously, it was reported that pituitary adenylate cyclase-activating polypeptide (PACAP) promotes sweating, but details of the underlying mechanism has not been clarified. We used immortalized human eccrine gland cells (NCL-SG3 cell) to investigate how sweat secretion is induced by PACAP. Intracellular Ca2+ levels were increased in these cells following their exposure to physiological concentrations of PACAP. Intracellular Ca2+ was not elevated when cells were concomitantly treated with PA-8, a specific PAC1-R antagonist, suggesting that PAC1-R is involved in the elevation of intracellular Ca2+ levels in response to PACAP treatment. Furthermore, immunocytochemistry experiments showed that aquaporin-5 was translocated from the cytoplasm to the cell membrane by PACAP. These results suggest that PACAP acts on eccrine sweat glands to promote sweat secretion by translocation of aquaporin-5 to the cell membrane in response to increased levels of intracellular Ca2+. These findings also provide a solid basis for future research initiatives to develop new therapies to treat sweating disorders.

Abstract
BACKGROUND Palmar and plantar hyperhidrosis (HH) is a common condition characterized by excessive sweating of the palms and soles. Botulinum neurotoxin (BTX) is a very effective and safe treatment. However, the associated intense injection pain is a major limiting factor deterring patients from selecting this treatment. OBJECTIVE The aim of this study was to review the numerous techniques used to minimize pain accompanying injections for palmoplantar HH. Additionally, the advantages and limitations of each modality will be discussed. MATERIALS AND METHODS The authors performed a comprehensive literature search in PubMed/MEDLINE, Embase, Cochrane Central, and Google Scholar on randomized controlled trials, cohort studies, and case series on techniques to relieve pain of BTX injections for treatment of palmar and plantar HH. RESULTS Current available techniques in reducing botulinum injection with merits and drawbacks are nerve blocks, Bier blocks, cryoanalgesia, needle-free anesthesia, topical anesthetics, and vibration anesthesia. CONCLUSION Topical anesthesia, ice, and vibration are the safest and most convenient noninvasive available methods to relieve pain associated with botulinum injection. Nerve blocks, Bier block, and needle-free anesthesia provide better anesthesia but are limited by the need for training and equipment.

Abstract
Background Primary plantar hyperhidrosis (PPH) is an idiopathic disease, characterized by excessive sweating of the feet. It leads to significant disturbance in private and professional daily lifestyle, due to excessive sweating. The aim of this study is to present the safety, efficacy and procedures of retroperitoneoscopic lumbar sympathectomy (RLS) for treatment of PPH. Methods RLS was performed 60 times in 30 patients (18 men, 12 women) with PPH in our institution from May 2019 to October 2020. All procedures were carried out by laparoscopy with retroperitoneal approach. Clinical data including patient demographics and perioperative, postoperative outcomes were evaluated. Recurrence of symptoms, and any adverse effects of surgery were evaluated after 7 to 30 days in outpatient clinic, and thereafter every 6 months. Results Mean age of patients was 33.6 (± standard deviation 10.8) years. Fourteen and fifteen patients were previously treated with medical therapy or endoscopic thoracic sympathectomy (ETS) respectively. Mean preoperative quality of life (QoL) score of patients was 91.8 (VERY BAD), but postoperative 12 months (QoL) score decreased to 29.1 (MUCH BETTER). There was no serious postoperative complication. During the mean 22 months of follow-up period, no compensatory sweating was observed. Conclusions RLS can be a safe and effective surgical treatment for severe PPH, especially for the patients with persistent plantar sweating even after conservative management and ETS. RLS also could be offered to surgeons who are familiar with retroperitoneal space anatomy as feasible surgical treatment for PPH.

Abstract
BACKGROUND Hyperhidrosis is responsible for various causes. The increased reactive oxygen radical production with insufficient antioxidant mechanism capacity may play a role in the etiopathogenesis of hyperhidrosis. It is probable to gather data about oxidative stress by detecting plasma thiol/disulfide ratio. The aim of this study was to determine whether thiol-disulfide balance changes in patients with hyperhidrosis. METHODS The files of patients who were diagnosed with hyperhidrosis in the dermatology outpatient clinic between 2015 and 2018 and whose native thiol, total thiol, and disulfide values were examined for any reason were examined. RESULTS Seventy-three patients were included in the study. 33 of the patients with hyperhidrosis were primary. Mean age; for primary hyperhidrosis patients (PHH) = 26.36 ± 7.61, primary hyperhidrosis (PHH) control group = 27.16 ± 7.94; secondary hyperhidrosis (SHH) patients = 47.88 ± 12.29, SHH control (45.40 ± 12.02). The native thiol values of PHH (469.93 ± 56.82 μmol/L) were higher than SHH (440.64 ± 62.72) (p = 0.024). However, as a result of thiol-disulfide comparison between hyperhidrosis patients (PHH and SHH) and control groups, disulfide levels increased (p = 0.04). In the PHH group, total thiol was measured as 512 ± 54.84 μmol/L, and SHH was measured as 484.11 ± 58.9 μmol/L, (p = 0.074). CONCLUSION Serum thiol levels in SHH increased more than PHH. As a result of thiol-disulfide comparison between hyperhidrosis patients and control groups, the balance shifted in favor of disulfide and oxidative side.

Abstract
Glycopyrronium tosylate cloth, an anticholinergic drug, has been approved for the topical treatment of primary axillary hyperhidrosis in the USA, but its effects in Japanese patients have not been previously investigated. This 4-week, randomized, double-blind, vehicle-controlled, multicenter study was conducted to evaluate the efficacy and safety of glycopyrronium tosylate cloth for primary axillary hyperhidrosis patients in Japan. Eligible patients, who were ≥9 years of age and had primary axillary hyperhidrosis ≥6 months, with gravimetrically-measured sweat production ≥50 mg/5 min, and Hyperhidrosis Disease Severity Scale ≥3 (moderate) were randomized 1:1:1 to once daily topical glycopyrronium tosylate 3.75%, 2.5%, or vehicle. Overall, 497 patients (163 in the glycopyrronium tosylate 3.75% group, 168 in the glycopyrronium tosylate 2.5% group, and 166 in the vehicle group, hereinafter in this order) were randomized. Statistically higher proportions of patients in the glycopyrronium tosylate groups achieved ≥2-point improvement in Hyperhidrosis Disease Severity Scale and ≥50% reduction in sweat production from baseline versus vehicle at week 4 (51.6%, 41.1%, and 16.4%, respectively; p < 0.001 in both cases). Higher responder rates in the glycopyrronium tosylate groups compared with the vehicle group occurred as early as week 1. The most common treatment-emergent adverse events in patients treated with glycopyrronium tosylate were photophobia, mydriasis, thirst, and dysuria. Most treatment-emergent adverse events were mild as determined by the investigators. The incidence of treatment-emergent adverse events leading to treatment modification was low in the three groups. The 4-week use of topical glycopyrronium tosylate improved the patient-reported outcome measure Hyperhidrosis Disease Severity Scale and objectively-evaluated sweat production with a favorable benefit/risk profile.

Abstract
BACKGROUND Endoscopic thoracic sympathectomy/sympathotomy is gold standard of treatment for primary hyperhidrosis. Compensatory hyperhidrosis following surgery and partial response to surgery in some patients can significantly affect surgery outcome and patient satisfaction. In this study we investigated predictors of success rate, side effects, and satisfaction of our patients following ETS over a 10-year period. METHODS We retrospectively reviewed result of 200 Endoscopic thoracic sympathotomy surgeries that was performed in a single center to treat craniofacial, palmar, or axillary primary hyperhidrosis over a 10-year period. Patients were asked to report success of surgery to resolve their primary hyperhidrosis, development of compensatory hyperhidrosis, its severity, and their overall satisfaction with surgery. RESULTS Palmar hyperhidrosis was resolved in 167 (94%) patients. Craniofacial hyperhidrosis was resolved in 66 (84%) patients. Axillary hyperhidrosis was resolved in 68 (50%) patients. Compensatory hyperhidrosis developed in 176 (88%) patients. 44 (22%) patients had mild CHH, 79 (40%) patients developed moderate CHH, and 52 (26%) patients experienced severe CHH. A total of 173 (87%) patients were satisfied with surgery. 19 (9%) patients were not satisfied with ETS and 8 (4%) patients regretted ETS. Lower body mass index and grade IV primary hyperhidrosis were found to be independent predictors of patient satisfaction. Pure axillary primary hyperhidrosis was a negative predictor of patient satisfaction. CONCLUSION Best results of ETS are achieved in patients with grade IV PHH and lower body mass indexes. Outcome of ETS for treating axillary PHH is not favorable.

Abstract
BACKGROUND Axillary hyperhidrosis characterized by excessive sweating in the axillary regions is a frustrating chronic autonomic disorder leading to social embarrassment, impaired quality of life and usually associated with palmoplantar hyperhidrosis. Identifying the condition and its cause is central to the management. AIM The aim of this article is to discuss treatment options for axillary hyperhidrosis. METHODS Comprehensive literature search using PubMed and Google Scholar was performed to review relevant published articles related to diagnosis and treatment of axillary hyperhidrosis. RESULTS Treatment modalities for axillary hyperhydrosis vary from topical and systemic agents to injectables, newer devices and surgical measures. None except for physical measures using devices or surgery, which destroys the sweat glands to remove them, is possibly permanent and most are associated with attendant side effects. CONCLUSION Several treatments including medical and surgical option are available for the treatment of axillary hyperhydrosis. Patient education is important component of its management. Individualized approach of management is necessary for optimal outcome of treatment.

PLoS One 2021; 16:e0254689.

Abstract
BACKGROUND Primary hyperhidrosis, excessive focal sweating is a common disease equally affecting men and women. Women tend to seek care more often and assess being more affected by hyperhidrosis in their daily life. The aim of this study was to explore experiences of living with primary hyperhidros in a sample of 15 women. METHODS Individual, semi-structured interviews with a purposive sample of 15 women diagnosed with primary hyperhidrosis and analysed by qualitative content analysis utilising an inductive approach. RESULTS The analysis resulted in a theme, constantly guarding the female image, based on three categories, misfitting the feminine norms, avoiding the attention of others and passing like any woman. Primary hyperhidrosis in women disrupted the ideal feminine appearance. Wearing clothes that concealed hyperhidrosis and distancing from social gatherings, in combination with negative remarks by others, created stress and anxiety and had a negative effect on self-esteem. Women felt poorly understood by others regarding the extent of their sweating and were misunderstood in intimate situations while trying to reduce the sweat production. Choices regarding education and career opportunities were affected, since being exposed and receiving attention due to primary hyperhidrosis was unwanted. Treatment with botulinum toxin liberated women from excessive sweating and removed a social handicap they described living with. CONCLUSION Primary hyperhidrosis in women disrupts the feminine appearance, lowers self-esteem and hinders social interactions. Clinicians assessing primary hyperhidrosis need to be aware that women may report the impairments from primary hyperhidrosis as being more associated with body image and appearance than with functional reductions in daily life. Educating patients, providing accurate information regarding the disease via media and cooperating with patient groups are important for increasing awareness and achieving progress in care for women with primary hyperhidrosis.

A phase III, 52-week, open-label study to evaluate the safety and efficacy of 5% sofpironium bromide (BBI-4000) gel in Japanese patients with primary axillary hyperhidrosis. J Dermatol 2021; 48:1149-1161. [PMID: 34041788 PMCID: PMC8453842 DOI: 10.1111/1346-8138.15927] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/18/2021] [Accepted: 04/06/2021] [Indexed: 11/27/2022]
Abstract
A long‐term study was conducted in Japanese patients with primary axillary hyperhidrosis who completed the preceding 6‐week phase III, confirmatory study of 5% sofpironium bromide gel (hereinafter referred to as sofpironium) to evaluate the safety and efficacy of 52‐week treatment with sofpironium. In the long‐term study, 185 patients who completed the confirmatory study (94 and 91 patients in the vehicle and sofpironium groups, respectively) started to receive sofpironium (switching and extension groups, respectively), and all these patients were included in both the full analysis set (FAS) and the safety analysis set (SAF). In the FAS, there were more females than males (73.0% vs. 27.0%), and median age was 38.0 years. A total of 161 patients (86 and 75 patients in the switching and extension groups, respectively) completed the study at week 52. The proportions of patients with hyperhidrosis disease severity score of 1 or 2 and a 50% or more reduction in total gravimetric weight of sweat were 57.4% in the switching group and 58.2% in the extension group at week 52. The proportions of patients who achieved this efficacy end‐point in the long‐term study were similar to that (53.9%) in the sofpironium group in the confirmatory study. In the SAF, the incidences of adverse events (AEs) were 80.9% in the switching group and 83.5% in the extension group, and the incidences of adverse drug reactions were 39.4% and 45.1%, respectively. AEs that occurred in at least 20% of patients in both treatment groups were application site dermatitis (25.5% and 33.0%, respectively) and nasopharyngitis (31.9% and 23.1%, respectively). Reported AEs were generally mild, and there were no deaths. Serious AEs occurred in three patients, but none were considered related to the study drug. In this study, the efficacy of sofpironium was maintained during 52‐week treatment, and no new safety risk was observed.
