Management of primary plantar hyperhidrosis with botulinum toxin type A: A retrospective case series of 129 patients. Australas J Dermatol 2024; 65:49-54. [PMID: 37964488 DOI: 10.1111/ajd.14188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 09/29/2023] [Accepted: 10/31/2023] [Indexed: 11/16/2023]
Abstract
BACKGROUND/OBJECTIVES To date, scientific data on the efficacy of botulinum toxin type A (BoNT-A) for primary plantar hyperhidrosis (PPH) are mainly derived from case reports and small case series. Herein, we sought to assess the efficacy and safety of BoNT-A for PPH on a large series of patients. METHODS Medical records of patients who were referred to the outpatient department for hyperhidrosis of a tertiary care hospital and received BoNT-A for PPH from March 2003 until December 2022 were reviewed. RESULTS A total of 129 patients [12 males, 117 females; median age 32 years (range, 16-72)] were included in the study, after excluding 24 patients with insufficient documented follow-up data. Most patients [115 (89.1%)] received onabotulinumtoxin-A, nine (7.0%) abobotulinumtoxin-A and five (3.9%) both in subsequent sessions. The mean number of sessions was 2.02 [standard deviation (SD), 2.29] and the mean duration of response 6.16 months (SD, 4.01). The percentage of response, as evaluated by Minor's test, was 71.67%, 63.44%, 47.78% and 34.13% after 1, 3, 6 and 9 months, respectively. Most patients were satisfied (21.7%) or very satisfied (58.9%) with the treatment. No serious side effects were reported. CONCLUSIONS The results of this retrospective study suggest that BoNT-A is an effective and safe treatment option for PPH.

Botulinum Toxin for the Management of Pelvic Floor Tension Myalgia and Persistent Pelvic Pain: A Systematic Review and Meta-analysis. Obstet Gynecol 2024; 143:e7-e17. [PMID: 37797336 DOI: 10.1097/aog.0000000000005388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Accepted: 06/29/2023] [Indexed: 10/07/2023]
Abstract
OBJECTIVE To systematically review the literature on use of botulinum toxin to treat pelvic floor tension myalgia and persistent pelvic pain. DATA SOURCES The ClinicalTrials.gov , PubMed, EMBASE, and Scopus databases were searched from inception to November 2022 by two independent assessors (B.L.K. and F.G.L.). Identified studies were screened by title and abstract and included after full-text review. Data extraction was subsequently performed and recorded in Microsoft Excel. METHODS This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines after registration in PROSPERO (CRD42022289132). All randomized studies, prospective studies with more than five participants, and retrospective studies with more than 10 participants published in English or French and assessing the use of botulinum toxin for the treatment of pelvic floor tension myalgia and persistent pelvic pain in women were included. Meta-analyses were performed on randomized data. TABULATION, INTEGRATION, AND RESULTS Of 4,722 articles identified, 24 satisfied inclusion criteria. A meta-analysis of five randomized controlled trials totaling 329 participants demonstrated no differences in patient- and clinician-reported outcome measures, including pain, dyspareunia, sexual function, and vaginal manometry. Mean duration of follow-up was 6 months. A qualitative analysis of 14 prospective and four retrospective studies including 804 participants is supportive of botulinum toxin; however, the quality of data is low, and there is marked heterogeneity between studies. CONCLUSION Meta-analyses of randomized data do not support the use of botulinum toxin to treat pelvic floor tension myalgia and persistent pelvic pain. Failure of these data to confirm the findings of nonrandomized prospective studies that suggest a treatment benefit may be attributable to the absence of placebo control and confounding outcomes obtained from an active comparator group. Further randomized controlled trials with true placebo are strongly recommended. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42022289132.

Abstract
PURPOSE Botulinum neurotoxin (BoNT) is a biological toxin produced by Clostridium botulinum. BoNT is a potent toxin extensively used in therapeutic interventions. This review provides an updated overview of the mechanisms of action and clinical applications of BoNT in head and facial region. STUDY SELECTION MEDLINE/PubMed searches were conducted using the terms "botulinum neurotoxin" and "dentistry" along with a combination of other related terms. In addition, studies were manually selected from reference lists of the selected articles. RESULTS The Food and Drug Administration in the United States initially approved BoNT to treat strabismus, blepharospasm, and hemifacial spasms. The use of BoNT in dermatology and cosmetics has been widely established and has created a revolution in these fields. Over the years, its applications in various medical specialties have expanded widely. Owing to its safety, efficacy, and long duration of action, it is well-accepted by patients. BoNT/A and BoNT/B are widely used in clinical practice. Several off-label uses of BoNT in the dental fraternity have yielded promising results. We have elaborated on the speculated mechanism of action, dosage, effective sites of injection, and adverse effects of each therapeutic application. The various clinical indications for BoNT include bruxism, myofascial pain, temporomandibular joint dislocation, hemifacial pain, orofacial dystonia, facial paralysis, chronic migraine, and trigeminal neuralgia. CONCLUSIONS BoNT is a safe treatment that can be used effectively, provided that the clinician has adequate knowledge regarding the mechanism, injection techniques, and local and systemic side effects and that it is administered cautiously and purposefully.

AbobotulinumtoxinA improves skin properties and sebum quality in the rhino mouse. Toxicon 2023; 233:107230. [PMID: 37517594 DOI: 10.1016/j.toxicon.2023.107230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 07/17/2023] [Accepted: 07/24/2023] [Indexed: 08/01/2023]
Abstract
Besides neuronal cells, botulinum neurotoxins (BoNTs) can also affect other cell types such as fibroblasts or keratinocytes. These cells play a key role in skin conditions. Maintaining a high-quality sebum secretion is essential to avoid premature aging. This study explored the effect of abobotulinumtoxinA (aboBoNT-A) in the rhino mouse. Briefly, anaesthetized animals were injected via the intra-dermal route (ID; four sites of injection) by either vehicle or 0.1, 0.3 and 1 Unit aboBoNT-A per mouse. A reference group was administered with adapalene gel 0.1% (daily local application) for 15 days. Adapalene is a third-generation retinoid and is used as first-line treatment of moderate acne. The body weight and the thickness of the dorsal skin were measured on days 1, 5, 10 and 15; erythema and scaling were recorded at the same time. On day 15, animals were ethically euthanized and skin samples were collected for histology, ELISA and lipidomic assays. AboBoNT-A administered ID at the doses 0.1 U and 0.3 U per mouse was well tolerated. 1 U aboBoNT-A (per mouse) induced a transient loss of muscle tone associated with a slight body weight loss after which mice recovered a good health status. AboBoNT-A did not show any significant effect on utricles surface area but induced a significant anti-inflammatory effect on dermis at the two highest doses. Moreover, aboBoNT-A showed neither side effects commonly observed with local retinoids, nor hyperplasia or dermis inflammation. No change in skin Interleukin-1alpha (IL-1α) cytokine levels was evidenced with aboBoNT-A, whereas a dose-dependent increase of substance P (SP) concentration in the skin was recorded, suggesting that aboBoNT-A induces neuropeptide accumulation in tissue by inhibiting exocytosis mechanisms. Lipidomic analysis showed that aboBoNT-A significantly increased the sebum concentration of several lipid species, presenting skin protecting properties. Overall, these data suggest that ID aboBoNT-A has skin rejuvenation, anti-inflammatory and moisture-boosting properties.

Bruxism and Botulinum Injection: Challenges and Insights. J Clin Med 2023; 12:4586. [PMID: 37510701 PMCID: PMC10380379 DOI: 10.3390/jcm12144586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 05/26/2023] [Accepted: 05/27/2023] [Indexed: 07/30/2023] Open
Abstract
Botulinum toxin (BTA) is a bacterial-derived extract that can inhibit muscle contraction, acting directly on the absorption of acetylcholine. Thanks to this property, botulinum has been used in aesthetic and general medicine for several years. Nowadays, the use of botulinum toxin is being deepened to address the problem of bruxism. In this scoping review, the results of the studies in the literature of the last 10 years were analyzed. Indeed, 12 reports (found on PubMed, Web of Science, and Scopus, entering the keywords "BRUXISM" and "BOTULINUM TOXIN") were deemed eligible for inclusion in this review. In the studies reviewed, BTA was injected into different muscle groups: masseters, masseter and temporalis or masseter, temporalis, and medial pterygoid. Botulinum toxin injection is a viable therapeutic solution, especially in patients with poor compliance or without improvement in conventional treatment.

Abstract
Background Primary palmar hyperhidrosis (PPH) is a condition marked by an overactive secretion of the hand's exocrine glands and is frequently hereditary. The profuse sweating associated with this condition can significantly impair the patient's daily activities and quality of life. Objective The objective of this study was to compared the benefits and drawbacks of thoracic sympathetic block and thoracic sympathetic radiofrequency in the treatment of PPH. Methods A retrospective analysis was conducted on 69 patients. They were divided into groups A and B according to their treatment. Group A (34 cases) received CT-guided percutaneous thoracic sympathetic nerve chain anhydrous alcohol chemical damage block, and group B (35 cases) received CT-guided percutaneous thoracic sympathetic nerve chain radiofrequency thermocoagulation. Results Palmar sweating disappeared immediately after the operation. The recurrence rates at 1, 3, 6, 12, 24, and 36 months were 5.88% vs. 2.86% (P > 0.05), 20.59% vs. 5.71% (P > 0.05), 32.35% vs. 11.43% (P < 0.05),32.35% vs. 11.43% (P < 0.05), 25% vs. 14.71% (P < 0.05), and 68.75% vs. 20.59% (P < 0.05), respectively. The incidence of intercostal neuralgia and compensatory hyperhidrosis was higher in group A compared with of group B (52.94% vs. 22.86%, P < 0.05; 55.88% vs. 22.86%, P < 0.05). Conclusion Both methods were found to be effective in treating PPH, but thoracic sympathetic radiofrequency had a longer-term effect, a lower recurrence rate, and a lower incidence of intercostal neuralgia and compensatory hyperhidrosis than a thoracic sympathetic block.

Pharmacovigilance-based drug repurposing: searching for putative drugs with hypohidrosis or anhidrosis adverse events for use against hyperhidrosis. Eur J Med Res 2023; 28:95. [PMID: 36829251 PMCID: PMC9951540 DOI: 10.1186/s40001-023-01048-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 02/07/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND Drug repurposing refers to the application of existing drugs to new therapeutic indications. As phenotypic indicators of human drug response, drug side effects may provide direct signals and unique opportunities for drug repurposing. OBJECTIVES We aimed to identify drugs frequently associated with hypohidrosis or anhidrosis adverse reactions (that is, the opposite condition of hyperhidrosis) from the pharmacovigilance database, which could be potential candidates as anti-hyperhidrosis treatment agents. METHODS In this observational, retrospective, pharmacovigilance study, adverse event reports of hypohidrosis or anhidrosis in the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) were assessed between January 2004 and December 2021 using reporting odds ratio (ROR) estimates and categorized by the World Health Organization Anatomical Therapeutic Chemical (ATC) classification code. The onset time of drug-associated hypohidrosis or anhidrosis was also examined. RESULTS There were 540 reports of 192 drugs with suspected drug-associated hypohidrosis or anhidrosis in the FAERS database, of which 39 drugs were found to have statistically significant signals. Nervous system drugs were most frequently reported (187 cases, 55.82%), followed by alimentary tract and metabolism drugs (35 cases, 10.45%), genitourinary system and sex hormones (28 cases, 8.36%), and dermatologicals (22 cases, 6.57%). The top 3 drug subclasses were antiepileptics, drugs for urinary frequency and incontinence, and antidepressants. Taking disproportionality signals, pharmacological characteristics of drugs and appropriate onset time into consideration, the main putative drugs for hyperhidrosis were glycopyrronium, solifenacin, oxybutynin, and botulinum toxin type A. Other drugs, such as topiramate, zonisamide, agalsidase beta, finasteride, metformin, lamotrigine, citalopram, ciprofloxacin, bupropion, duloxetine, aripiprazole, prednisolone, and risperidone need more investigation. CONCLUSIONS Several candidate agents among hypohidrosis or anhidrosis-related drugs were identified that may be redirected for diminishing sweat production. There are affirmative data for some candidate drugs, and the remaining proposed candidate drugs without already known sweat reduction mechanisms of action should be further explored.

Abstract
BACKGROUND Although botulinum toxin type A (BTX-A) injection has been proved to reduce topical sebum secretion, the impact of intradermal BTX-A injection on scalp sebum production has never been reported. OBJECTIVES The purpose of this study was to investigate the efficacy and safety of intradermal BTX-A treatment vs intradermal normal saline (NS) injection for scalp sebum secretion regulation. METHODS This multicenter, randomized, double-blinded, prospective study recruited patients complaining of oily scalp and/or hair. The patients were randomly allocated to receive either 1 session of intradermal BTX-A or NS injection. The baseline and posttreatment scalp sebum secretion at 24, 48, 72, and 96 hours postshampooing was measured with a Sebumeter SM815 (Cutometer Dual MPA 580, Courage & Khazaka, Cologne, Germany) at 1, 3, 4, and 6 months after treatment. The patients' comments, satisfaction, and adverse events were evaluated and compared. RESULTS In total, 25 patients in the BTX-A group and 24 patients in the NS group completed the follow-up. For the treated region, compared with NS, intradermal BTX-A treatment (50-65 U) significantly reduced scalp sebum secretion at 24, 48, and 72 hours postshampooing at the 1- and 3-month follow-up visits (P < 0.05). No significant difference between the 2 groups was observed at 4 and 6 months after the treatment. The patients' satisfaction ratings were significantly higher for the BTX-A treatment (P = 0.000). No serious adverse events occurred. CONCLUSIONS Compared with NS, 1 session of intradermal BTX-A injection (50-65 U) effectively and safely reduced scalp sebum secretion and greasiness perception in the treated region at 24 and 48 hours postshampooing for 3 months.

Abstract
Primary palmar hyperhidrosis (PPH) is a pathologic condition of excessive sweating on hands that has adverse impacts on patients’ social activity, professional life, and psychological state. Endoscopic thoracic sympathicotomy (ETS) is by far the treatment choice for PPH with the most stable and durable curative effects, but special attention should be given to the side effects of the surgery, especially compensatory hyperhidrosis (CH). This consensus is the second version of the Chinese Expert Consensus on the Surgical Treatment of PPH by the China Expert Committee on Palmar Hyperhidrosis (CECPH), which was published 10 years ago. This consensus emphasizes the need for special attention and careful assessment of the patients’ feelings, as well as their emotional and mental state, and emphasizes that distress due to palmar sweating and the desire for treatment are prerequisites for diagnosis. It also provides a more nuanced delineation of CH and reviews all new attempts to prevent and treat this side effect. New evidence of the epidemiology, pathogenesis of PPH, and indications for surgery were also assessed or recommended.

Abstract
The autonomic nervous system (ANS), composed of the sympathetic and parasympathetic nervous systems, acts to maintain homeostasis in the body through autonomic influences on the smooth muscle, cardiac muscles, blood vessels, glands and organs of the body. The parasympathetic nervous system interacts via the cranial and sacral segments of the central nervous system, and the sympathetic nervous system arises from the T1–L2 spinal cord segments. After a spinal cord injury (SCI), supraspinal influence on the ANS is disrupted, leading to sympathetic blunting and parasympathetic dominance resulting in cardiac dysrhythmias, systemic hypotension, bronchoconstriction, copious respiratory secretions and uncontrolled bowel, bladder, and sexual dysfunction. Further, afferent signals to the sympathetic cord elicit unabated reflex sympathetic outflow in response to noxious stimuli below the level of SCI. This article outlines the pathophysiology of SCI on the ANS, clinical ramifications of autonomic dysfunction, and the potential long-term sequelae of these influences following SCI.

Abstract
BACKGROUND Axillary osmidrosis(AO) and primary hyperhidrosis(PH) are common diseases, but there are still difficulties in treatment. Microwave therapy may become a new method. OBJECTIVE To evaluate long-time efficacy of patients with AO or PH treated by microwave. To discuss possible mechanism of microwave therapy by combining results of clinical and pathological. METHODS Ten AO or PH patients with moderate or severe level were selected as subjects, and each subject received microwave treatment of bilateral armpits. The follow-up period lasted two years,and the changes of perspiration and odor were evaluated in subjective and objective ways. Each subject took skin biopsy in the treatment area before and after treatment or each follow-up. HE and immunohistochemical staining were performed. RESULTS Both subjective and objective index reflected the significant improvement of AO and PH after treatment(P<0.05). Dermatology life quality index score decreased by 10.4±4.6(P<0.05). The number of apocrine glands decreased significantly after treatment, and most of them changed from secretory phase to quiescent phase. CONCLUSIONS Microwave therapy can destroy apocrine sweat glands, reduce number of functional glands, so as to improve symptoms of AO and PH and elevate quality of life, which is safe, effective and stable.

Abstract
Among the forms of idiopathic hyperhidrosis, those involving the forehead have the greatest impact on patients’ quality of life, as symptoms are not very controllable and are difficult to mask for patients. Although the local injection therapy with Incobotulinum toxin type A (IncoBTX-A therapy) can be considered a rational treatment, data from the literature describing both efficacy and safety of the treatment over the long term are poor. The aim of this report is to describe the single-center experience of five patients seeking treatment, for forehead hyperhidrosis with IncoBTX-A. To evaluate the benefits, safety profile and duration of anhidrosis, patients were treated following a standardized procedure and then followed until clinical relapse. The amount of sweating was measured by gravimetric testing, the extension of hyperhidrosis area was measured through Minor’s iodine starch test, and response to the treatment was evaluated using the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI). In all treated patients, a significant anhidrotic effect was observed 4 weeks after the treatment and lasted for approximately 36 weeks. The reduction in sweat production was associated with significant amelioration of symptoms and quality of life for all treated patients. No serious side effects occurred; one patient complained of a mild transient bilateral ptosis. Although further wider studies are required, our preliminary results seem to encourage the use of IncoBTX-A in forehead hyperhidrosis.

Abstract
BACKGROUND Botulinum toxin (BT), a potent neurotoxin, has been used in clinical medicine since the 1970s for cosmetic and therapeutic purposes. Studies have consistently shown positive outcomes with a very limited adverse effect profile and a conventional understanding that results dissipate after 3 to 5 months. However, more recent evidence suggests that changes in muscle composition, function, and appearance persist for much longer, even years. To examine the potential implications of these findings on cosmetic use of BT injections in reduction of skin lines and wrinkles, we first needed to further our understanding of the current literature on long-term outcomes after repeated BT injections. METHODS A comprehensive review of the literature on long-term outcomes after repeated BT injections for cosmetic indications was performed. We evaluated the study designs, and results were compared. RESULTS A total of 22 publications met our inclusion criteria, of which 14 were clinical trials. Few studies extended outcome measurement past 6 months postinjection, and many were funded or supported by industry. However, the studies that extended follow-up saw persistent changes after BT injection, in some cases as far as 4 years postinjection. CONCLUSION The current body of knowledge on the long-term results after repeated cosmetic BT injections is very limited, and the available literature provides insufficient evidence on how prolonged effects could alter clinical use of BT. Further clinical studies with extended follow-up periods with inclusion of both subjective and objective measured outcomes of appearance and muscle function are required to better understand the long-term impacts of repeated BT injections.

Abstract
BACKGROUND Botulinum toxin type A is widely used to treat primary axillary hyperhidrosis and has proven to be an effective and safe approach. Onabotulinumtoxin A was approved by the FDA as a treatment for primary axillary hyperhidrosis. This study aimed to evaluate the efficacy and safety of Neu-BoNT/A in subjects diagnosed with primary axillary hyperhidrosis. METHODS The Hyperhidrosis Disease Severity Scale, gravimetric measurement of sweat, and Global Assessment Scale were analyzed at weeks 4, 8, 12, and 16 to determine the effect of treatment. Adverse events, physical examination, and vital signs were monitored. RESULTS Subjects treated with Neu-BoNT/A showed statistically significant improvement by all 3 methods at weeks 4, 8, 12, and 16 (P value = 0.00). There were no severe adverse events or significant changes in vital signs, physical examination, or laboratory tests. CONCLUSION Neu-BoNT/A can be effectively and safely used for primary axillary hyperhidrosis. LEVEL OF EVIDENCE II This journal requires that authors assign a level of evidence to each article.

Discrimination of the Activity of Low-Affinity Wild-Type and High-Affinity Mutant Recombinant BoNT/B by a SIMA Cell-Based Reporter Release Assay. Toxins (Basel) 2022; 14:toxins14010065. [PMID: 35051041 PMCID: PMC8780439 DOI: 10.3390/toxins14010065] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 01/05/2022] [Accepted: 01/13/2022] [Indexed: 12/12/2022] Open
Abstract
Botulinum neurotoxin (BoNT) is used for the treatment of a number of ailments. The activity of the toxin that is isolated from bacterial cultures is frequently tested in the mouse lethality assay. Apart from the ethical concerns inherent to this assay, species-specific differences in the affinity for different BoNT serotypes give rise to activity results that differ from the activity in humans. Thus, BoNT/B is more active in mice than in humans. The current study shows that the stimulus-dependent release of a luciferase from a differentiated human neuroblastoma–based reporter cell line (SIMA-hPOMC1-26-Gluc) was inhibited by clostridial and recombinant BoNT/A to the same extent, whereas both clostridial and recombinant BoNT/B inhibited the release to a lesser extent and only at much higher concentrations, reflecting the low activity of BoNT/B in humans. By contrast, the genetically modified BoNT/B-MY, which has increased affinity for human synaptotagmin, and the BoNT/B protein receptor inhibited luciferase release effectively and with an EC50 comparable to recombinant BoNT/A. This was due to an enhanced uptake into the reporter cells of BoNT/B-MY in comparison to the recombinant wild-type toxin. Thus, the SIMA-hPOMC1-26-Gluc cell assay is a versatile tool to determine the activity of different BoNT serotypes providing human-relevant dose-response data.

Hyperhidrosis treatments in hidradenitis suppurativa: A systematic review. Dermatol Ther 2021; 35:e15210. [PMID: 34796606 DOI: 10.1111/dth.15210] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 11/13/2021] [Indexed: 11/30/2022]
Abstract
Hyperhidrosis impairs quality of life (QOL) in hidradenitis suppurativa (HS) patients and may exacerbate HS. However, there is limited literature on whether hyperhidrosis treatments improve HS disease. To systematically review literature on efficacy and tolerability of hyperhidrosis treatments in HS patients. In May 2021, MEDLINE and EMBASE databases were systematically searched by two reviewers per PRISMA guidelines for articles on hyperhidrosis and HS. Sixteen articles met inclusion criteria (2 randomized controlled trials [RCTs], one case-control study, three cross-sectional studies, 10 case-studies/series), encompassing 252 HS patients across studies. They examined botulinum toxin A (BTX-A) (n = 6) and B (BTX-B) (n = 1), suction-curettage (n = 1), diode laser (n = 1), and microwave-based energy device (MED) (n = 3). Overall, BTX treatments improve HS severity, QOL, hyperhidrosis, and were well-tolerated. Suction-curettage did not improve disease. One HS patient tolerated diode laser well, with improvement in sweating and HS. One RCT studying MED was discontinued due to adverse events. Two studies reported MED-induced HS. BTX was overall helpful in HS patients, including in patients without concomitant hyperhidrosis. However, more prospective studies are needed to examine its utility in HS. There is potential harm of MEDs in HS. Most studies examining hyperhidrosis treatments in HS patients are low level of evidence. Larger RCTs should examine the efficacy and tolerability of hyperhidrosis treatments in HS.

Abstract
Background Primary plantar hyperhidrosis (PPH) is an idiopathic disease, characterized by excessive sweating of the feet. It leads to significant disturbance in private and professional daily lifestyle, due to excessive sweating. The aim of this study is to present the safety, efficacy and procedures of retroperitoneoscopic lumbar sympathectomy (RLS) for treatment of PPH. Methods RLS was performed 60 times in 30 patients (18 men, 12 women) with PPH in our institution from May 2019 to October 2020. All procedures were carried out by laparoscopy with retroperitoneal approach. Clinical data including patient demographics and perioperative, postoperative outcomes were evaluated. Recurrence of symptoms, and any adverse effects of surgery were evaluated after 7 to 30 days in outpatient clinic, and thereafter every 6 months. Results Mean age of patients was 33.6 (± standard deviation 10.8) years. Fourteen and fifteen patients were previously treated with medical therapy or endoscopic thoracic sympathectomy (ETS) respectively. Mean preoperative quality of life (QoL) score of patients was 91.8 (VERY BAD), but postoperative 12 months (QoL) score decreased to 29.1 (MUCH BETTER). There was no serious postoperative complication. During the mean 22 months of follow-up period, no compensatory sweating was observed. Conclusions RLS can be a safe and effective surgical treatment for severe PPH, especially for the patients with persistent plantar sweating even after conservative management and ETS. RLS also could be offered to surgeons who are familiar with retroperitoneal space anatomy as feasible surgical treatment for PPH.

Perianal Hyperhidrosis Successfully Treated with Botulinum Toxin A. Skin Appendage Disord 2021; 7:404-407. [PMID: 34604333 DOI: 10.1159/000515492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Accepted: 02/25/2021] [Indexed: 11/19/2022] Open
Abstract
Perianal hyperhidrosis (HH) is a rare form of primary focal HH and may become a major problem for the patient with a significant psychosocial burden and negative impact on the quality of life. Botulinum toxin injections are widely used as a second-line treatment option for axillary, palmar, and plantar HH with a good safety profile. Herein, we pre-sent a case of primary perianal HH successfully treated with Botulinum toxin A at a dose higher than that previously reported in literature, with a longer response, a higher degree of satisfaction, and no adverse effects. Moreover, we review the main aspects of the perianal anatomy that are essential to carry out the technique correctly and make dermatologists achieve expertise with the procedure.

Abstract
Botulinum toxin is a superfamily of neurotoxins produced by the bacterium Clostridium Botulinum with well-established efficacy and safety profile in focal idiopathic hyperhidrosis. Recently, botulinum toxins have also been used in many other skin diseases, in off label regimen. The objective of this manuscript is to review and analyze the main therapeutic applications of botulinum toxins in skin diseases. A systematic review of the published data was conducted, following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Botulinum toxins present several label and off-label indications of interest for dermatologists. The best-reported evidence concerns focal idiopathic hyperhidrosis, Raynaud phenomenon, suppurative hidradenitis, Hailey–Hailey disease, epidermolysis bullosa simplex Weber–Cockayne type, Darier’s disease, pachyonychia congenita, aquagenic keratoderma, alopecia, psoriasis, notalgia paresthetica, facial erythema and flushing, and oily skin. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and doses protocols for off label applications.

Abstract
Abstract
Background
Hyperhidrosis is an excess sweat secretion. Various modalities of treatment exist for hyperhidrosis. Although medical treatment is the first line of treatment, its long-term outcome is not satisfactory. In this study, we compared the results of thoracoscopic excision with that of radiofrequency ablation of the sympathetic chain as a treatment of palmar hyperhidrosis.
Results
During the period from January 2014 to December 2017, 42 patients with palmar hyperhidrosis after failure of medical treatment presented to Departments of Pediatric Surgery and Neurosurgery, Faculty of Medicine. They were 26 males and 16 females. Their ages ranged between 11 and 42 years (mean 21.78 years). Twenty patients underwent thoracoscopic excision of the sympathetic chain (in Pediatric Surgery Department), while 22 patients underwent radiofrequency ablation of the sympathetic chain (in Neurosurgery Department). For the thoracoscopic sympathectomy group, the mean operative time was 27.39 min, the mean length of hospital stay was 24.78 h, the mean sweating scale decreased from 3.28 preoperatively to 1.33 1 year postoperatively, and the main postoperative complication was compensatory hyperhidrosis (40%). For the radiofrequency ablation group, the mean operative time was 55 min, the mean length of hospital stay was 20.64 h, the mean sweating scale decreased from 3.29 preoperatively to 1.57 1 year postoperatively, and the main postoperative complication was recurrence of hyperhidrosis (27%).
Conclusion
Thoracoscopic excision is more effective than radiofrequency ablation of the sympathetic chain in improving palmar hyperhidrosis. However, it has a higher risk of developing compensatory hyperhidrosis.

Abstract
Background: Major depressive disorder (MDD) is a serious mental disorder that represents a substantial public health problem. Several trials have been undertaken to investigate the role of botulinum toxin type A (BTX-A) in the treatment of MDD, but the conclusions were controversial. To examine the efficacy and safety of BTX-A vs. placebo on patients with a clinical diagnosis of MDD, we conducted this systematic review and meta-analysis. Methods: A systematic search was conducted for all relevant randomized controlled trials (RCTs) in PubMed and Web of Science from inception to June 17, 2020. All published studies that investigated the efficacy and safety of BTX-A injections on patients with a clinical diagnosis of MDD were included. The overall effect size was summarized using a random-effects meta-analysis model. The primary outcomes of the present meta-analysis were the changes in depressive rating scale at week 6 after BTX-A injection compared with placebo. The safety of BTX-A injections also was assessed. Results: Five RCTs with a total of 417 participants (189 patients in the BTX-A group, 228 patients in placebo group) were eligible in this meta-analysis. The results indicated an overall positive effect of BTX-A injections for reducing the depressive symptoms of patients with MDD (Hedges' g, -0.82; 95% CI, -1.38 to -0.27) with large effect size. Differences are likely explained by the dose of BTX-As and the gender of the participants. Our findings also highlighted that BTX-A injections were generally well-tolerated, with only mild and temporary adverse events reported. Conclusions: The present meta-analysis provides evidence that BTX-A injections are associated with a statistically significant improvement in depressive symptoms. BTX-A injections are generally safe and may provide a new, alternative option for the treatment of depression.
