How to Prevent, Reduce, and Treat Severe Post Sympathetic Chain Compensatory Hyperhidrosis: 2021 State of the Art

Front Surg. 2022 Jan 3;8:814916. doi: 10.3389/fsurg.2021.814916. eCollection 2021.

ABSTRACT

The role of thoracic surgery in the management of hyperhidrosis is well-known and thoracoscopic sympathetic interruption is commonly accepted as being the most effective treatment. However, some concerns still remain regarding the potential to develop compensatory hyperidrosis (CH), the most troublesome and frequent side effect after surgery and its management. Compensatory hyperidrosis prevention may be achieved by identifying subjects at higher risk and/or targeting nerve interruption level on the base of single patient characteristics gathered during the preoperative survey. Furthermore, the surgical treatment may consist of different techniques aimed at reversing the effects of previous sympathetic interruption. To predict CH after sympathectomy, the most interesting proposals in recent literature are a temporary thoracoscopic sympathetic block and the introduction of new and targeted preoperative surveys. If the role of nerve clipping technique vs. the definitive cutting is still intensely under debated, new approaches have been recently proposed to reduce the incidence of CH. In particular, extended sympathicotomy has been described as an alternative to overcome severe forms. Last, among the techniques developed to reverse sympathetic interruption effect, diffuse sympathicotomy (DS) and microsurgical sympathetic trunk reconstruction represent advances in this field. An all-round review of these topics is strongly needed. Our aim is to cover all the above issues point by point. Although sympathectomy represents a small part of thoracic surgery, we believe that it is worthy of interest because of the profound effect that complications for a benign condition can have on patients.

Long-term follow-up in quality of life before and after endoscopic thoracic sympathicotomy in 367 patients with palmar hyperhidrosis

Ann Palliat Med. 2022 Jan 10:apm-21-2860. doi: 10.21037/apm-21-2860. Online ahead of print.

ABSTRACT

BACKGROUND: Palmar hyperhidrosis (PH) hinders daily activities and deteriorates quality of life (QOL). Endoscopic thoracic sympathicotomy (ETS) is safe and efficient as the gold standard treatment for PH. So far, the long-term change of QOL after surgery has not been fully characterized, which is important to evaluate clinical benefits and helped to identify the true beneficiaries. In the current study, we aimed to investigate the long-term outcome of ETS by comparing their preoperative QOL with a follow-up QOL.

METHODS: This study enrolled 367 patients with PH who underwent ETS between March 2018 and March 2019. All patients were surveyed by a web-based questionnaire adapted from de Campos Quality-of-life Questionnaire for Evaluation of Hyperhidrosis, and compared to their preoperative results.

RESULTS: After a median follow-up of 14 months [interquartile range (IQR), 9-21 months], improvement in QOL was reported in 90.7% of patients. Compared to preoperative QOL [median (Md) =40, IQR, 37-45], postoperative QOL was significantly improved (Md =20, IQR, 13-23; P<0.001). A higher QOL score was noticed in patients with severer PH at diagnosis, whereas no significant difference was observed among postoperative QOL regarding the severity of PH. Subclinical compensatory hyperhidrosis (CH) occurred in 94.6% of post-ETS cases after long-term follow-up. The score of postoperative QOL was significantly positively correlated to the severity of CH (rs=0.14; P=0.009).

CONCLUSIONS: Improvement in QOL sustained for a long-term period after receiving ETS for PH. Almost all patients developed subclinical CH on other body sites in the long run, with an impairment in QOL correlating with the severity of CH. Further investigations on the developing patterns of CH and clinical coping strategy are warranted to improve the long-term outcome of ETS.

Knowledge of surgical management of hyperhidrosis among primary care physicians and the general public

Interact Cardiovasc Thorac Surg. 2022 Jan 7:ivab371. doi: 10.1093/icvts/ivab371. Online ahead of print.

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.

Comparison of 10 versus 20 sessions tap water iontophoresis efficacy in the treatment of palmoplantar hyperhidrosis

J Cosmet Dermatol. 2022 Jan 4. doi: 10.1111/jocd.14723. Online ahead of print.

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.

Conservative Management of Median Nerve Brachial Plexopathy after Microwave-based MiraDry Treatment for Axillary Hyperhidrosis

Plast Reconstr Surg Glob Open. 2021 Dec 15;9(12):e3992. doi: 10.1097/GOX.0000000000003992. eCollection 2021 Dec.

ABSTRACT

Axillary hyperhidrosis is characterized by excessive sweating of the armpits, which can significantly affect quality of life. A new microwave-based therapy, MiraDry (Miramar labs, Sunnyvale, Calif.), is a promising minimally-invasive treatment option. We report a case of unilateral brachial plexus thermal injury in a thin 19-year-old man treated for axillary hyperhidrosis with the MiraDry system. He initially experienced swelling and pain in the left hand and was prescribed 1 week of methylprednisolone. He then presented 1 week later with induration and swelling of bilateral axillae with swelling of left thumb, left index, and left long fingers, decreased sensation in median nerve distribution of the left hand, and the inability to flex the left index finger DIP joint. EMG showed absent median nerve motor and sensory function, consistent with median nerve plexopathy. He was conservatively managed with close observation and regular occupational hand therapy appointments. At his 12-month follow-up, there was complete return of left pronator teres strength, thumb flexion, and index finger flexion. Decreased sensation remained at the tip of the left index finger. We report the case of median nerve palsy after MiraDry therapy for axillary hyperhidrosis in a thin young man. We recommend using low-energy settings and pre-procedural ultrasound for young, thin patients because of the more superficial course of the brachial plexus within the axilla.

Sofpironium bromide: an investigational agent for the treatment of axillary hyperhidrosis

Expert Opin Investig Drugs. 2021 Dec 10. doi: 10.1080/13543784.2022.2017880. Online ahead of print.

ABSTRACT

INTRODUCTION: In the last years, increased knowledge about pathophysiology of primary hyperhidrosis has led to novel therapeutic advances. Topical and systemic anticholinergic agents have been proven beneficial in reducing sweat production in primary axillary hyperhidrosis (PAH), although their use is limited by the increased likelihood of systemic anticholinergic drug reactions, particularly regarding the systemic agents.

AREAS COVERED: This paper provides an overview of pharmaceutical characteristics, efficacy and safety data from phase II and III clinical trials on sofpironium bromide (SB), a topical anticholinergic agent which has been employed for the treatment of PAH and has already received its first approval in Japan for the treatment of PAH in the form of 5% gel formulation.

EXPERT OPINION: The retrometabolic drug design of topical SB presents distinct advantages, by limiting systemic absorption and therefore development of anticholinergic adverse events. This along with the popularity of the non-greasy gel formulation is expected to increase compliance. However, this therapy still offers a temporary control of PAH, compared to sympathectomy or device-based treatments, such as microwave thermolysis. Hence, physicians should balance the effectiveness against adverse events of each therapeutic modality and use a personalized approach based on patient’s needs.

Palmar Hyperhidrosis Associated with the Azygos Lobe

Kyobu Geka. 2021 Dec;74(13):1086-1090.

ABSTRACT

A 66-year-old man visited our department because of palmar hyperhidrosis. Computed tomography had revealed division of the right upper lobe by a fissure and the azygos vein, and the presence of an azygos lobe had been diagnosed. Endoscopic thoracic sympathectomy (resection of T3 ganglion) was performed. Adhesion between the azygos lobe and parietal pleura was dissected to pulling out the azygos lobe and the sympathectomy was safely performed.

Hyperhidrosis: the neglected sign in heart failure patients

Am J Cardiovasc Dis. 2021 Oct 25;11(5):635-641. eCollection 2021.

ABSTRACT

Profuse sweating is a symptom often reported by cardiological patients and could be also an early phenomenon of adaptation or rather cardiac maladaptation in the context of incipient heart failure (HF). By definition, in HF patients the low cardiac output causing reduced renal blood supply and reduced pressure in the arterial baroreceptors activate compensatory mechanisms such as the RAAS and the adrenergic autonomic nervous system. The retention of fluids caused by the decompensation of heart-kidney system could generate a reactive hyperhidrosis and even anticipate an incipient decompensation and might prevent manifest volume overload. Moreover, in HF patients the overactive sympathetic nervous system generates an increase in the reabsorption of fluids in the kidney, on the other hand it generates a signaling to the sweat glands to induce a dispersion of fluids, with loss of sodium and chlorine at the glandular ductal level. Finally sweat gland production physiology during physical activity is also altered in HF patients. This review is focused on sweating and its pathophysiological role in heart failure. Although all the mechanisms underlying this phenomenon are not fully understood, there are interesting connections that might explain this fluid elimination as a wise and sophisticated way to prevent incipient heart failure crisis. Future research could be focused on studying new drugs that selectively would be able to promote fluid elimination by this specific way in patients suffering from heart failure.
