Primary focal hyperhidrosis and autonomic symptom burden: a case-control study using the COMPASS-31 questionnaire

Clin Auton Res. 2025 Dec 13. doi: 10.1007/s10286-025-01178-w. Online ahead of print.

ABSTRACT

PURPOSE: To explore the relationship between primary focal hyperhidrosis (PFH) and generalized autonomic dysfunction, we assessed autonomic symptom burden using a comprehensive and validated measure of autonomic symptoms.

METHODS: In this case-control study, we compared 132 patients with PFH with 74 matched healthy controls. Autonomic symptoms were assessed using the Composite Autonomic Symptom Score-31 (COMPASS-31) questionnaire. Propensity score matching minimized confounding. Mann-Whitney U tests compared COMPASS-31 scores between groups. A sensitivity analysis using multivariate linear regression accounted for specific hyperhidrosis sites and demographic factors.

RESULTS: PFH cases demonstrated significantly higher median COMPASS-31 scores compared to controls (18.7 [IQR 7.7-34.8] vs. 11.2 [IQR 3.5-19.3], p < 0.001). Significant differences were observed in orthostatic (2.0 [0-20] vs. 0 [0-12], p = 0.028), vasomotor (0 [0-0] vs. 0 [0-0], p = 0.005; 24.2% vs. 9.5% non-zero scores, respectively), secretomotor (3.2 [2.1-8.6] vs. 0 [0-3.8], p < 0.001), and gastrointestinal (5.4 [1.8-8] vs. 1.8 [0.9-5.4], p = 0.004) domains. Sensitivity analysis confirmed PFH status as a significant predictor of higher COMPASS-31 scores (additional 7.5 points on average, 95% CI 1.6-13.4, p = 0.012) after adjusting for demographic factors and hyperhidrosis sites. Craniofacial and truncal hyperhidrosis were associated with higher autonomic symptom burden.

CONCLUSION: PFH is associated with a broader spectrum of autonomic symptoms beyond localized sweating, establishing a link to more generalized autonomic dysfunction. These findings underscore the need for a comprehensive approach to evaluating and managing patients with PFH.

Development and Validation of the Japanese Version of the Hyperhidrosis Quality of Life Index

J Dermatol. 2025 Dec 10. doi: 10.1111/1346-8138.70101. Online ahead of print.

ABSTRACT

Hyperhidrosis decreases an individual’s quality of life (QOL). The Hyperhidrosis Quality of Life Index (HidroQoL) measures the impact of hyperhidrosis on QOL and has established reliability and validity. However, a Japanese version does not exist. Hence, this study aimed to develop the Japanese version of the HidroQoL (HidroQoL-J) and verify its reliability and validity. The first survey included 528 participants (272 males, 256 females, mean age ± standard deviation 41.89 ± 15.24 years) who met the criteria for hyperhidrosis and scored ≥ 2 on the Hyperhidrosis Disease Severity Scale (HDSS). The second survey was conducted for reliability and included 210 participants (105 males, 105 females, mean age ± standard deviation 43.56 ± 14.60 years). The main survey items were (1) HidroQoL-J, (2) Dermatology Life Quality Index (DLQI), (3) Skindex-16, and (4) Anxiety Scale Specific to Hyperhidrosis Symptoms (ASSHS). Confirmatory factor analysis revealed the HidroQoL-J had a two-factor structure: a “daily life activities domain” with six items and a “psychosocial life domain” with 12 items, as in the original English version of the instrument. Cronbach’s alphas (α) for the HidroQoL-J were 0.93, 0.85, and 0.91 for overall, daily life activities, and psychosocial life, respectively. Test-retest reliability was r = 0.70, 0.67, and 0.69 for overall, daily life activities, and psychosocial life (all p < 0.001), respectively. Furthermore, the intraclass correlation coefficients were 0.70, 0.67, and 0.69, respectively. Moderate positive correlations were observed between the overall HidroQoL-J score and the DLQI (r = 0.56) and Skindex-16 (r = 0.43) scores (all p < 0.001). There was also a moderate positive correlation between the overall score of the HidroQoL-J and HDSS (r = 0.42) and a weak positive correlation with ASSHS (r = 0.39) (all p < 0.001). Therefore, the HidroQoL-J exhibited sufficient reliability and validity to measure the impact of hyperhidrosis symptoms on QOL.

Botulinum Toxin as a Tool to Reduce Hyperhidrosis in Amputees

Cutis. 2025 Oct;116(4):131-132. doi: 10.12788/cutis.1274.

ABSTRACT

Botulinum toxin (BTX) is an effective treatment for improving prosthetic discomfort and reducing limb pain in amputees, particularly those experiencing hyperhidrosis of the residual limb. We describe a technique for administering BTX injections by dividing the residual limb into targeted areas and delivering the treatment in stages. This approach demonstrated an excellent outcome in our patient, enhancing comfort and managing hyperhidrosis. Our case underscores the importance of personalized treatment plans that are tailored to each patient’s needs while also addressing factors that may affect their access to effective therapies.

Compensatory hyperhidrosis following endoscopic thoracic sympathectomy: a 5-year follow-up study of risk factors and symptom progression

J Cardiothorac Surg. 2025 Dec 8. doi: 10.1186/s13019-025-03720-3. Online ahead of print.

ABSTRACT

BACKGROUND: Compensatory hyperhidrosis (CH) is a common complication after endoscopic thoracic sympathectomy (ETS) for hyperhidrosis. Despite its prevalence, long-term data on CH progression and associated risk factors are scarce. This study aimed to evaluate the risk factors and progression of CH during a 5-year follow-up period.

METHODS: This study retrospectively analyzed 138 patients with primary palmar hyperhidrosis (PPH) who underwent endoscopic thoracic sympathectomy between January 2014 and December 2019. All patients received bilateral single-port thoracoscopic sympathectomy and were followed up at 1, 3, and 5 years postoperatively. The severity of postoperative sweating was assessed using the Hyperhidrosis Disease Severity Scale (HDSS). Univariate and multivariate logistic regression analyses were performed to identify risk factors associated with the development and progression of CH.

RESULTS: A total of 138 patients were included in the study, with 78.9% reporting the occurrence of CH after surgery and 23.8% of them experiencing severe CH. HDSS scores gradually increased over the 5-year postoperative period, indicating symptom worsening. Further analysis revealed that bilateral R4-level sympathectomy significantly increased the risk of CH progression (OR = 4.28, 95% CI: 1.27-15.60, P = 0.021) while having three or more affected areas was identified as a protective factor (OR = 0.19, 95% CI: 0.05-0.63, P = 0.008).

CONCLUSION: This study found that compensatory hyperhidrosis is relatively common in patients undergoing ETS, and symptoms may progressively worsen over time. The level of sympathetic nerve resection and the number of affected areas are key predictive factors for symptom progression.

Three-Year Results Following Microwave Therapy in Patients with Severe Primary Axillary Hyperhidrosis

Aesthetic Plast Surg. 2025 Dec 1. doi: 10.1007/s00266-025-05469-5. Online ahead of print.

ABSTRACT

Microwave therapy (Miradry®) is an approved treatment for axillary hyperhidrosis (AH). There are several studies in the literature that show favourable safety and efficacy profile, although a few follow up patients under longer period and on larger cohort patients. In the present study, we report three-year results after microwave therapy for AH. At dermatology clinic in Östergötland 103 patients with severe AH received one or two Miradry® treatments, between 2020 and 2022. Patients were examined at several intervals during study period. Between March 2024 and June 2025, 87 patients were contacted by post and asked to complete HDSS (Hyperhidrosis Disease Severity Scale) and Hyperhidrosis Quality of Life (HidroQoL©); 45 patients have responded to our survey (response rate 51.7%). Statistically significant improvement was observed in both HDSS (from medians 3 at the study inclusion to medians 2 at 3 year) and HidroQoL© (medians 26 at baseline and medians 6 at 3 year). As a conclusion, our data demonstrate that microwave therapy is a promising long-term efficient treatment for AH and significantly improves quality of life in patients suffering from severe AH.Level of Evidence II This journal requires that authors assign a level of evidence to each article.

Is There a Risk of Recurrence That Would Discourage Sympathicotomy for Hyperhidrosis in Minors?

J Clin Med. 2025 Nov 19;14(22):8194. doi: 10.3390/jcm14228194.

ABSTRACT

Background/Objectives: Primary palmar hyperhidrosis (PPH) is a socially debilitating condition that often begins in adolescence. Although sympathicotomy is a low-risk procedure, there are conflicting opinions about the optimal time for surgery: some recommend it at onset in adolescence, while others are cautious because of the risk of recurrence associated with juvenile neuroplasticity. The primary objective was to assess the recurrence rate; secondary objectives included the management of hyperhidrosis, compensatory sweating onset, and satisfaction. Methods: This retrospective cohort study included sympathicotomy procedures for palmar hyperhidrosis performed between 2004 and 2024 in patients younger than 18 years with a preoperative Hyperhidrosis Disease Severity Scale (HDSS) class of 4. Quantitative data are presented as medians and interquartile ranges, while categorical data are presented as numbers and percentages. Results: 28 patients were included, of whom 4 underwent single-stage surgery and 24 two-stage surgery. The median age was 17.30 years, with no gender predominance. At a median follow-up of 75 months, the recurrence rate was 10.71%. Twenty-two patients experienced compensatory sweating, with the majority (60.7%) reporting mild symptoms and the remainder reporting moderate. The median patient satisfaction score was 9.34 (range 9-10). Conclusions: Even though PPH typically begins during adolescence, there is no consensus on the appropriateness of sympathicotomy for younger patients, primarily due to concerns about recurrence. Our data, characterized by long-term follow-up and large numbers of minors, are consistent with those observed in adults’ cohorts in terms of hyperhidrosis management, compensatory sweating rates, and, particularly, recurrence rates, supporting the surgical approach even at a young age.

Can large language models respond health education questions for patients with palmar hyperhidrosis? A comparative study of ChatGPT and DeepSeek

Digit Health. 2025 Nov 13;11:20552076251396576. doi: 10.1177/20552076251396576. eCollection 2025 Jan-Dec.

ABSTRACT

OBJECTIVE: To compare the adaptability of two large language models: ChatGPT and DeepSeek in responding to health education questions related to patients with palmar hyperhidrosis.

METHODS: Based on clinical guidelines and expert experience, 17 health education questions relevant to palmar hyperhidrosis were developed and posed separately to ChatGPT and DeepSeek. Twelve experienced thoracic surgery experts independently evaluated the adaptability of the responses generated by both models. Each response was rated using a five-point Likert scale to quantitatively analyze the adaptability of the information provided.

RESULTS: Both language models demonstrated good adaptability in addressing health education questions related to palmar hyperhidrosis. In the English context, 10 responses of ChatGPT received a full score (5 points) from more than 50% of experts, while DeepSeek did so for 8. In the Chinese context, both ChatGPT and DeepSeek receive 10 responses a full score (5 points) from more than 50% of experts. ChatGPT outperformed DeepSeek in the English-language setting, whereas DeepSeek showed superior overall performance in the Chinese context.

CONCLUSION: This preliminary study demonstrates that both ChatGPT and DeepSeek are capable of effectively addressing health education questions for patients with palmar hyperhidrosis. ChatGPT performs better in English-language setting, while DeepSeek shows greater adaptability in Chinese-language context. However, human review remains essential to ensure the accuracy and reliability of the provided information in practical applications.

Scar-concealed 2 + 3 mm dual-port thoracoscopic sympathectomy for palmar hyperhidrosis: single-center outcomes

Front Surg. 2025 Oct 24;12:1664901. doi: 10.3389/fsurg.2025.1664901. eCollection 2025.

ABSTRACT

OBJECTIVE: To minimize the trauma and incision of the operation for primary palmar hyperhidrosis (PPH), we have designed a inconspicuous scar thoracoscopic bilateral thoracic sympathetic chain transection via “2 + 3 mm” two-pinhole incisions (ISTTST). This study mainly retrospectively compares and analyzes the pros and cons of this surgical method vs. the conventional single-port thoracoscopic sympathetic nerve transection (CSTTST).

METHODS: Data of patients with moderate or severe PPH and underwent thoracic sympathetic chain transection were collected. Patients undergoing ISTTST and those receiving CSTTST were included in the two-pinhole group and the single-port group respectively. The baseline characteristics, intraoperative and postoperative conditions of the two groups were compared.

RESULTS: A total of 265 patients were enrolled, including 162 in the single-port group and 103 in the two-pinhole group. There were no statistically significant differences in baseline conditions such as gender, age, BMI, age of onset of PPH, hyperhidrosis sites, hyperhidrosis degree, and transection level of thoracic sympathetic chain between the two groups (P > 0.05). The two-pinhole group had shorter operation time (19.809 ± 3.356 min vs. 22.534 ± 4.541 min), lower postoperative incision pain score (1.563 ± 0.518 vs. 2.012 ± 0.788), and better incision satisfaction (9.437 ± 0.498 vs. 8.068 ± 1.424) (all P < 0.001). There were no statistically significant differences in postoperative conditions such as surgical effect, 24-h postoperative discharge rate, postoperative complication rate, postoperative compensatory hyperhidrosis, postoperative recurrence rate of PPH, and postoperative follow-up time between the two groups (P > 0.05).

CONCLUSION: The ISTTST is a more concealed-scar, minimally invasive, and convenient procedure, meeting the aesthetic needs. Compared with the CSTTST, it has certain advantages and deserves more attention and attempts.
