Hyperhidrosis increases the risk of postoperative infections after shoulder arthroplasty and rotator cuff repair

JSES Int. 2025 May 26;9(5):1623-1629. doi: 10.1016/j.jseint.2025.04.034. eCollection 2025 Sep.

ABSTRACT

BACKGROUND: Hyperhidrosis (HH), or excessive sweating, has been associated with higher rates of infections. Despite being a relatively common condition, its impact on postoperative outcomes following orthopedic procedures in proximity to the axilla, such as rotator cuff repair (RCR) and shoulder arthroplasty (SA), remains unknown.

METHODS: A retrospective cohort study was conducted using the TriNetX globally federated database. Patients with and without HH who underwent either RCR or SA were matched based on patient demographics and comorbidities. A standard difference of <0.1 was used to assess success of propensity score matching. Primary outcomes were 90-day postoperative superficial soft tissue infections (SSTIs), deep infections, and wound complications. Tests of significance and risk ratios (RR) with 95% confidence intervals were calculated.

RESULTS: After matching, 2,941 patients who underwent RCR and 2,066 patients who underwent SA were identified in each cohort. HH patients undergoing RCR demonstrated a higher risk of SSTIs (RR = 1.81; P = .007), urinary tract infection (UTI; RR = 2.09; P < .001), and emergency services usage (RR = 1.69; P < .001). Similarly, HH patients undergoing SA were also at higher risk of SSTIs (RR = 1.87; P = .004), UTI (RR = 1.65; P = .003), and emergency services usage (RR = 1.54; P < .001). There was no significant difference in the rates of deep soft tissue infections between the HH and non-HH groups for both RCR and SA.

DISCUSSION: HH is associated with an increased risk for 90-day complications including SSTIs, UTIs, and emergency services usage following both RCR and SA. Additional strategies for optimizing surgical care of these patients should be investigated.

Pleural effusion following thoracoscopic sympathectomy in a patient with palmar hyperhidrosis

BMC Pulm Med. 2025 Oct 2;25(1):446. doi: 10.1186/s12890-025-03933-1.

ABSTRACT

Thoracoscopic sympathectomy can be used to treat primary hyperhidrosis (PH). Nonetheless, there is a paucity of literature addressing the postoperative complications associated with this procedure. We report a case of a 21-year-old male patient who developed prolonged bilateral pleural effusion after undergoing thoracoscopic sympathectomy for PH. This case aims to raise awareness of this rare complication and discuss effective management strategies for it.

Hyperhidrosis: Diagnosis and management strategies

Nurse Pract. 2025 Oct 1;50(10):31-36. doi: 10.1097/01.NPR.0000000000000354. Epub 2025 Sep 25.

ABSTRACT

Hyperhidrosis, a condition characterized by an overactive cooling system that produces four to five times the normal amount of sweat, can profoundly impact a person’s physical, psychological, and social well-being. It can be classified as primary or secondary, and the location and severity determine treatment options. These options include topical agents, systemic agents, and nonsurgical and surgical procedures. Nurse practitioners play a crucial role in managing this condition, and their awareness and understanding are vital in designing effective treatment options for their patients. This article aims to enhance knowledge by discussing hyperhidrosis, its impact on a patient’s physical and psychological well-being, and recommended treatment modalities.

Development of a Nomogram Model for Predicting Anxiety Risk in Patients With Hyperhidrosis: A Study Involving 234 Patients

J Dermatol. 2025 Sep 18. doi: 10.1111/1346-8138.17965. Online ahead of print.

ABSTRACT

Primary focal hyperhidrosis (HH) carries a substantial psychosocial burden, and anxiety is a common but underrecognized comorbidity. We developed and internally validated a nomogram to estimate individualized anxiety risk in primary HH and examined robustness in prespecified sensitivity analyses. We retrospectively analyzed 234 consecutive patients with primary HH at a single center (June 2020-August 2023). Eligibility followed Hornberger criteria; secondary causes were excluded by history/physical examination, medication review, and targeted laboratory tests when indicated. Anxiety was diagnosed clinically according to CCMD-3. After LASSO prescreening with a priori clinical inclusion, the final multivariable logistic model retained 10 readily available predictors: diabetes, intolerance to cold, intolerance to heat, male sex, fatigue, and sweating at the head, hand, foot, chest, and neck. Internal validation used 1000-bootstrap optimism correction to assess discrimination and calibration; clinical utility was quantified with decision-curve analysis (DCA) across threshold probabilities of 0.02-0.36. The nomogram showed good discrimination (optimism-corrected C-index 0.826) and good calibration (bootstrap-corrected MAE 0.033, Brier 0.219). Three prespecified sensitivity analyses yielded consistent conclusions: SA1 (no diabetes) C-index 0.827, Brier 0.221, MAE 0.043; SA2 (craniofacial involvement + number of involved sites) C-index 0.839, Brier 0.220, MAE 0.028; and SA3 (stricter exclusion) C-index 0.811, Brier 0.211, MAE 0.045. Across thresholds of 0.02-0.36, all models demonstrated positive net benefit versus treat-none with largely overlapping curves. This transparent, internally validated tool may help identify HH patients at high risk of anxiety and support timely psychological intervention; external multicenter validation is warranted.

Atypical Presentations of Levator Ani Syndrome With Perianal Hyperhidrosis: A Case Series

ACG Case Rep J. 2025 Sep 11;12(9):e01826. doi: 10.14309/crj.0000000000001826. eCollection 2025 Sep.

ABSTRACT

Levator ani syndrome (LAS) explains up to 7.4% of anorectal pain cases. Classic symptoms include rectal pain or pressure with sitting. We present 2 patients, ages 32 and 25 years, presenting initially with “diarrhea” and perianal hyperhidrosis. History revealed rectal discomfort, tenesmus, urgency, and sensation of incomplete evacuation. Puborectalis tenderness was present on digital rectal examination. Therapies were tailored to each patient, including pelvic floor physical therapy with biofeedback, bowel regulation, rectal diazepam, and ileostomy. These presentations offer insights into potential pathophysiological mechanisms in LAS and highlight the importance of considering LAS in non-pain presentations.

Unilateral versus Bilateral T3 Ganglionectomy in Primary Palmar Hyperhidrosis Patients

Thorac Cardiovasc Surg. 2025 Sep 11. doi: 10.1055/a-2699-8163. Online ahead of print.

ABSTRACT

BACKGROUND: Primary palmar hyperhidrosis (PPH) is a distressing condition that significantly impairs quality of life. Endoscopic thoracic sympathectomy (ETS) is an effective treatment, but compensatory hyperhidrosis (CH) remains a common and problematic complication. The optimal extent of surgical interruption, particularly the choice between unilateral and bilateral ganglionectomy, remains uncertain.

METHODS: We conducted a retrospective analysis of 118 patients who underwent unilateral (n=41) or bilateral (n=77) T3 ganglionectomy via video-assisted thoracoscopic surgery (VATS) between November 2023 and January 2025. Patient-reported outcomes, including CH and postoperative satisfaction, were assessed three months postoperatively using standardized questionnaires. Comparisons between the two groups were performed using t-tests and chi-square tests.

RESULTS: Baseline demographics were comparable between groups. The unilateral group reported significantly higher satisfaction, with 93% “very satisfied” compared to 61% in the bilateral group (p<0.001). CH was less prevalent in the unilateral group (20% vs. 48%, p=0.007), and when present, was generally mild and limited to a single body region. In contrast, bilateral ganglionectomy was associated with more frequent and multi-regional CH. Among unilateral ETS patients, only 22% later underwent contralateral surgery, indicating that unilateral intervention was sufficient in most cases.

CONCLUSIONS: Unilateral T3 ganglionectomy offers a favorable balance of efficacy and safety, yielding higher satisfaction and significantly reduced CH compared to bilateral procedures. These findings support the use of unilateral ETS as a first-line surgical strategy for PPH, particularly in patients sensitive to CH. A tailored, staged approach may enhance long-term outcomes and patient satisfaction.

Polydatin ameliorates hyperhidrosis by targeting Aqp5 in a mouse model

Front Pharmacol. 2025 Aug 13;16:1589143. doi: 10.3389/fphar.2025.1589143. eCollection 2025.

ABSTRACT

BACKGROUND: Primary focal hyperhidrosis (PFH) is a neurological dermatological disorder characterized by localized, excessive sweating. Current treatments have limitations, and postoperative compensatory hyperhidrosis remains a concern. Aquaporin 5 (AQP5) and neurologic factors such as Brain-Derived Neurotrophic Factor (BDNF) and Neuregulin-1 (NRG-1) are known to play key roles in sweat regulation. Polydatin, a natural compound with anti-inflammatory and neuroregulatory properties, has shown therapeutic potential in related conditions.

METHODS: This preclinical experimental study investigated the effects of Polydatin in a mouse model of hyperhidrosis. Mice were treated with different doses and durations of Polydatin. Aqp5 knockout mice were used to explore the AQP5-related pathway. Sweat gland function, gene and protein expression (AQP5, BDNF, NRG-1), and cell responses to acetylcholine stimulation were analyzed.

RESULTS: Polydatin at 50 mg/kg/day significantly reduced sweat secretion in hyperhidrotic mice (p < 0.001), while treatment duration showed no significant impact. The therapeutic effect was absent in Aqp5 knockout mice, confirming AQP5 dependence. Polydatin downregulated mRNA and protein expression of AQP5, Na+-K+-Cl– Cotransporter 1 (NKCC1), BDNF, and NRG-1. Additionally, Polydatin inhibited acetylcholine-induced proliferation of sweat gland cells (p < 0.05), an effect abolished by Aqp5 knockdown.

CONCLUSION: Polydatin alleviates hyperhidrosis by targeting AQP5 and suppressing key neurologic factors, supporting its potential as a novel therapeutic approach for PFH.

Efficacy and Safety of Treatments for Primary Palmar Hyperhidrosis: A Systematic Review Assessing Patient-Centric Outcomes

Dermatol Res Pract. 2025 Aug 20;2025:8867838. doi: 10.1155/drp/8867838. eCollection 2025.

ABSTRACT

Background: Primary palmar hyperhidrosis (PH) is a chronic condition characterized by excessive sweating in the palms, significantly affecting the quality of life (QOL) of affected individuals. Despite the availability of various treatment modalities, the long-term efficacy and safety of these interventions remain unclear, warranting a comprehensive evaluation. This systematic review aims to assess the efficacy, safety and patient-reported outcomes of treatments for PH. Methods: A systematic search was conducted in PubMed, Embase and the Cochrane Library from their inception until March 2024, adhering to PRISMA guidelines. Inclusion criteria focused on prospective and retrospective studies examining PH treatments published in English. Data from eligible studies were extracted, analysed qualitatively and reported based on outcomes, including efficacy, QOL improvements and adverse effects. Results: Fourteen studies, including 1733 patients aged 4-77 years, were included in the final review. The treatments assessed included oral and topical oxybutynin, iontophoresis, botulinum toxin A injections, photodynamic therapy (PDT) and endoscopic thoracic sympathectomy (ETS). Oral oxybutynin demonstrated symptomatic relief in 60%-97% of the patients although anticholinergic side effects were frequently reported. ETS, while providing the highest rates of complete sweat cessation, was associated with compensatory hyperhidrosis. Noninvasive treatments like iontophoresis showed moderate efficacy with minimal side effects but required ongoing sessions for maintenance. Conclusion: This review highlights the efficacy of several therapeutic approaches for PH though most treatments are hindered by significant adverse effects or practical limitations. Future research should prioritize long-term studies and standardized outcome measures to guide clinical decision-making more effectively.
