J Dermatol. 2022 Apr 7. doi: 10.1111/1346-8138.16368. Online ahead of print.

ABSTRACT

Head and forehead hyperhidrosis (HFH) is a disease that causes a large amount of sweating from the head region, and it significantly reduces patients’ quality of life. Only a few reports have shown the effectiveness of botulinum toxin type A (BTX-A) local injection therapy (BTX-A therapy) for HFH. To clarify the benefits of BTX-A for HFH, BTX-A therapy was performed in 15 patients, and its efficacy was evaluated. The amount of sweating was measured by the ventilation capsule method and Minor’s iodine-starch test. Evaluation was also performed using the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI). In most cases, a remarkable antiperspirant effect was observed from 2 weeks after the injection, and the effect lasted for approximately 30 weeks. HDSS and DLQI improved along with the decrease in sweating. Two patients (13.3%) complained of transient mild ptosis. There were no serious side-effects. This study showed that BTX-A therapy is a safe and effective treatment for HFH.

A Practical Approach to the Diagnosis and Treatment of Palmar Hyperhidrosis

Plast Reconstr Surg Glob Open. 2022 Mar 7;10(3):e4172. doi: 10.1097/GOX.0000000000004172. eCollection 2022 Mar.

ABSTRACT

Palmar hyperhidrosis (PH), a condition characterized by excess sweating of the palms, is a common concern that presents to the plastic surgeon, which can have major impacts on patient confidence and quality of life. While several studies summarize treatment options for hyperhidrosis in general, few outline the therapeutic options available specifically for PH.

METHOD: The authors reviewed the current literature specific to the diagnostic workup and treatment of PH.

RESULTS: In this article, we show a practical approach to managing patients presenting with PH, summarize its main nonsurgical and surgical treatment options, provide a suggested treatment ladder, and outline emerging therapeutic approaches. We suggest that, after diagnosing PH and classifying its severity, nonsurgical treatments (ie, topical antiperspirants, iontophoresis, botulinum toxin A injection, and topical/oral anticholinergics) should be utilized in a stepwise manner. In patients with severe palmar hyperhidrosis who do not respond to nonsurgical treatments, surgical intervention may be warranted, generally in the form of sympathetic denervation.

CONCLUSION: This article provides a clear overview of PH treatment options, stepwise guidelines for physicians, and educational video resources demonstrating botulinum toxin A injections with cryotherapy and nerve blocks.

Cohort study on 20 years’ experience of bilateral video-assisted thoracic sympathectomy (VATS) for treatment of hyperhidrosis in 2431 patients

Sao Paulo Med J. 2022 Feb 21:S1516-31802022005004202. doi: 10.1590/1516-3180.2021.0078.R1.23072021. Online ahead of print.

ABSTRACT

BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation.

OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series.

DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil.

METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated.

RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample.

CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

Unexpected improvement of hyperhidrosis with cannabidiol

Einstein (Sao Paulo). 2022 Feb 14;20:eRC5795. doi: 10.31744/einstein_journal/2022RC5795. eCollection 2022.

ABSTRACT

Hyperhidrosis is characterized by excessive sweating and it affects almost 5% of the population. The affected age group is wide, and it can affect from children to elderlies. There are two types of hyperhidrosis: generalized and focal. Treatment depends on the symptoms presented. In more severe cases, radiofrequency sympatholysis and bilateral thoracic sympathectomy are the options. However, recurrence is possible or the postoperative appearance of conditions called compensatory hyperhidrosis or reflex hyperhidrosis. We describe two cases of patients treated with Cannabidiol who had significant and unexpected improvement of hyperhidrosis. The first patient received Cannabidiol specific for public presentations at work, and the second patient had a diagnosis of autism spectrum disorder. The hyperhidrosis improved in both patients immediately after using Cannabidiol.

Minimally Invasive Sympathicotomy for Palmar Hyperhidrosis and Facial Blushing: Current Status and the Hyperhidrosis Expert Center Approach

J Clin Med. 2022 Jan 31;11(3):786. doi: 10.3390/jcm11030786.

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.

Setting research priorities for management and treatment of hyperhidrosis: the results of the James Lind Alliance Priority Setting Partnership

Clin Exp Dermatol. 2022 Feb 5. doi: 10.1111/ced.15122. Online ahead of print.

ABSTRACT

BACKGROUND: Hyperhidrosis is a common skin condition characterised by excessive sweating, which can negatively impact on quality of life. It is under-researched compared with other conditions of similar prevalence.

OBJECTIVE: To generate a top ten list of research priorities for the treatment and management of hyperhidrosis, with equal input from people with hyperhidrosis and healthcare professionals.

METHODS: A priority setting partnership was established and processes from the James Lind Alliance Handbook were followed. An online survey asked participants what questions they would like research to answer. These questions were grouped into ‘indicative questions’ which were ranked in a second survey of 45 indicative questions. The top 23 questions were taken to a final workshop event attended by key stakeholders, and ranked to generate the top ten list of research priorities.

RESULTS: There were 592 questions submitted by 268 respondents for the first survey. For the second survey, 286 participants ranked the indicative questions in order of priority. At the final workshop, the top ten list was generated. The top three priorities were; Are there any safe and effective permanent solutions for hyperhidrosis?, what is the most effective and safe oral treatment (drugs taken by mouth) for hyperhidrosis? and what are the most effective and safe ways to reduce sweating in particular areas of the body?

CONCLUSIONS: There are many unanswered research questions that people with hyperhidrosis and healthcare professionals would like to see answered. The results from this PSP will help to ensure future research funding can be directed to these areas of priority.

Subcutaneous tissue necrosis with fat liquefaction, hematoma, inflammatory mass after microwave-based treatment for axillary hyperhidrosis

J Cosmet Dermatol. 2022 Jan 31. doi: 10.1111/jocd.14820. Online ahead of print.

ABSTRACT

Axillary hyperhidrosis (AH) and bromhidrosis are common complaint in Asians for consultation in dermatology.A microwave-based device has gradually become a first-choice option during this decade because of the safety and efficacy both for axillary hyperhidrosis and osmidrosis. Other complications reported are transient median and ulnar neuropathy, brachial plexus injury with sensory and motor dysfunction. We herein report a rare case of subcutaneous tissue necrosis with fat liquefaction, hematoma that occurred after microwave-based treatment. It took three weeks for both sides to recover completely. The case prompt us that one pass treatment for the same treatment area and cooling to relieve the pain for 24 hours. Appropriate restriction of movement should be emphasized within one month after treatment. Moreover, more caution is needed when bumps enlarged rapidly .

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.
