Long term outcomes and risk factors of compensatory hyperhidrosis after thoracoscopic sympathectomy in primary palmar hyperhidrosis patients: a retrospective single-center study

J Cardiothorac Surg. 2024 Oct 4;19(1):590. doi: 10.1186/s13019-024-03086-y.

ABSTRACT

OBJECTIVE: This study aims to evaluate the long-term outcomes of compensatory hyperhidrosis (CH) after thoracoscopic sympathectomy and explore the risk factors affecting postoperative CH in primary palmar hyperhidrosis(PPH) patients.

METHOD: A retrospective analysis was conducted on patients who underwent thoracoscopic sympathectomy in the thoracic surgery department of our hospital from January 2015 to May 2022. Long-term follow-up surveys was conducted to collect data on post-operative satisfaction, PPH recurrence, and CH occurrence. Postoperative CH outcomes were assessed using the HDSS and satisfaction scores scale. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative CH.

RESULT: A total of 152 patients was included in the final study, with 113 cases in the CH group and 39 cases in the nCH group. The incidence of postoperative CH was 74.3% (113/152), within which 33.6% (38/113) were severe CH. The median follow-up time was 3.1 years(2.5-5.5y) and the median interval of CH onset after surgery was 30 days (14-90d). Univariate analysis showed that body mass index(BMI), surgical time, and transected nerve level are correlated with CH, with statistically significant differences. Multivariate logistic regression analysis indicated a higher BMI (OR = 0.864, 95% CI 0.755-0.989, P < 0.05) is the independent risk factor for the occurrence of CH. There was no statistically significant difference in HDSS scores among CH patients at 1 month, 1 year, and 3 years after surgery.

CONCLUSION: A higher BMI is the independent risk factor for postoperative CH after thoracoscopic sympathectomy. The incidence and severity of postoperative CH kept stable during a long term follow up.

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.

Cluster analysis identifies clinical phenotypes of primary hyperhidrosis

Skin Pharmacol Physiol. 2024 Aug 28. doi: 10.1159/000540516. Online ahead of print.

ABSTRACT

Introduction Identifying subgroups of patients with primary hyperhidrosis (PHH) can improve the understanding of the disease pathophysiology. The study objective is to determine the naturally occurring subgroups of patients with PHH based on clinical characteristics. Methods In this retrospective cohort study, data was collected from participants included in a clinical trial. The data was collected between January 2020 and June 2021 from outpatients with PHH attending a dermatologic department in Denmark. Overall, 84 patients with PHH were screened for inclusion in the clinical trial. Of these, 41 met the eligibility criteria. Four participants were excluded because of missing data. The main outcome was the identification of subgroups of patients with PHH using an unsupervised hierarchical cluster analysis. Results Overall, 37 patients were included (28 [76.7%] females; median age at inclusion 28.0 [interquartile range (IQR) 24.0-38.3]; median body mass index 24.9 [IQR 20.9-27.4); median age of onset 13.0 [IQR 9.5-18.5]; and 26 [70.3%] had a familial disposition towards PHH). Two clusters of 18 and 17 patients were identified. The first cluster had, when compared to the second, a younger age of onset (median age 11.0 [IQR 0-13.0] vs. 17.0 [IQR 15.0-21.0], p=0.003) and higher sweat rates on gravimetry (median 175.0 [IQR 121.2-252.5] vs. 40.0 [IQR 20.0-60.0] milligrams of sweat/5 minutes, p&lt;0.001) and transepidermal water loss (median 93.7 [IQR 91.2-97.8] vs. 59.0 [IQR 44.4-73.2] grams/meter2/hour, p&lt;0.001). No differences were observed for the other variables. Conclusions This study identifies two subgroups of patients with PHH. The patients with an onset of PHH during childhood had a substantially higher sweat and evaporation rate in adulthood than those with an onset during adolescence. These findings may imply a changed understanding of the pathophysiology of PHH, by indicating that an early disease onset can lead to a worse disease course.

Epidemiology and health care of hyperhidrosis in Germany: claims data analysis

BMJ Open. 2024 Aug 12;14(8):e085862. doi: 10.1136/bmjopen-2024-085862.

ABSTRACT

BACKGROUND AND OBJECTIVES: Data on the population-based epidemiology of hyperhidrosis (HH) are scarce. This study investigated the epidemiology and healthcare of HH in Germany.

DESIGN AND SETTING: Claims data of adult persons insured by a German statutory health insurance (DAK-Gesundheit) between 2016 and 2020 were analysed. Included were persons aged 18 years and older with a diagnosis of HH (confirmed inpatient or outpatient diagnosis in the observation year) who were continuously insured. Following outcomes were measured: prevalence and incidence rates, severity of hyperhidrosis and inpatient and outpatient care by a group of specialists.

RESULTS: In 2020, 0.70% of insured adults were confirmed to have HH (mean age 59.5 years, SD 18.9, 61.6% female), with 9.24% having a ‘localised’ form, 8.65% a ‘generalised’ form and 84.80% an ‘unspecified’ form. 0.04% of the total population had a severe form. The incidence was 0.35%. Localised HH was more common in younger age groups (18 to <30 years), while older age groups (70 to <80 years) were significantly more likely to suffer from generalised HH. Systemic anticholinergics were used in 4.55%, and botulinum toxin injection therapy in 0.81%. General practitioners were most frequently involved in care. Inpatient stays due to HH were very rare, with 0.14% in 2019 and 0.04% in 2020.

CONCLUSION: Multisource data analysis connecting primary and secondary data will be needed for a complete picture of the healthcare and epidemiology of HH.

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.

Shapiro’s syndrome: episodic hypothermic hyperhidrosis

BMJ Case Rep. 2024 Jul 29;17(7):e260998. doi: 10.1136/bcr-2024-260998.

ABSTRACT

SummaryShapiro’s syndrome is a rare neurological disease. The triad of Shapiro’s syndrome includes episodes of hyperhidrosis, hypothermia and complete/partial agenesis of the corpus callosum. We report a case of a young male who had episodic chills, increased sweating and fatigue. During these episodes, he was found to have bradycardia, hypotension and hypothermia. Clinical and neurological examinations were unremarkable. The MRI of the brain revealed agenesis of the corpus callosum. There was a good response to carbamazepine therapy.

Hyperhidrosis and Neurofibromatosis Type 1: A Case Report

Cureus. 2024 Jun 24;16(6):e63021. doi: 10.7759/cureus.63021. eCollection 2024 Jun.

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.
