Abstract
Botulinum toxin type A (BoNT-A) was first isolated in 1946, and since then, several formulations have been developed and widely used to treat wrinkles by inducing muscle paralysis. This multicenter, double-blind, randomized, parallel-group, active-controlled phase 3 clinical trial was designed to evaluate the efficacy and safety of a newly developed BoNT-A formulation, BMI2006, in improving moderate to severe glabellar wrinkles and to compare with existing onabotulinumtoxin A (OBoNT) injections. A total of 276 subjects were enrolled and received 20 units of the randomized material, which was intramuscularly injected into five different locations on the forehead. The primary endpoint, assessed at 4 weeks, showed no statistically significant difference in the improvement rate of glabellar wrinkles between the two groups, with BMI2006 demonstrating non-inferiority to comparator BoNT-A. Secondary endpoints, evaluated by both treating investigators and independent investigators, also exhibited similar improvement rates throughout the study period. Both groups reported high levels of satisfaction with no statistical difference between the two groups. Safety evaluations indicated mild and transient adverse events, with no serious reactions observed. In conclusion, BMI2006 is an effective and safe BoNT-A for treating glabellar wrinkles with an expected duration of action between 8 and 12 weeks.

Clinical investigation of botulinum toxin (prabotulinumtoxin A) for bruxism related to masseter muscle hypertrophy: A prospective study. J Craniomaxillofac Surg 2023:S1010-5182(23)00076-8. [PMID: 37353404 DOI: 10.1016/j.jcms.2023.05.005] [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: 10/13/2022] [Revised: 03/22/2023] [Accepted: 05/21/2023] [Indexed: 06/25/2023] Open
Abstract
This study aims to confirm the effectiveness and safety of a prabotulinumtoxin type A (praBTX-A) injection in patients with bruxism and masseter hypertrophy. The study included patients who ground or clenched their teeth while sleeping and had computed tomography (CT) scans that showed a maximum thickness of the masseter muscle of 15 mm or more. The praBTX-A was administered bilaterally into the masseter muscles; 15 U/side for group 1, 25 U/side for group 2, and 35 U/side for group 3. CT scans and bruxism questionnaires were conducted before and eight weeks after the injection. Thirty-seven patients were enrolled, but three dropped out due to loss of follow-up. After injection, masseter thickness decreased to 15.1 ± 2.0 mm for group 1, 14.3 ± 2.9 mm for group 2, and 13.4 ± 1.8 mm for group 3 (p = 0.043). Group 3 showed a statistically significant lower masseter thickness compared to group 1 (p = 0.039). Both subjective and objective frequencies of bruxism decreased for all groups, but there were no significant differences in either subjective (p = 0.396) or objective frequencies (p = 0.87) between the groups after the injection. The results of this study suggest that praBTX-A injection is a safe and effective treatment for bruxism and masseter hypertrophy. A dosage of 35 IU/side can effectively decrease masseter thickness and relieve bruxism symptoms. Even the minimum dosage of 15 IU/side can contribute to improvements in bruxism symptoms. This investigation provides valuable information for managing bruxism that is associated with hypertrophic masseter muscles.

[PMID: 36463753 DOI: 10.1016/j.rehab.2022.101711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 09/07/2022] [Accepted: 09/26/2022] [Indexed: 12/03/2022]
Abstract
BACKGROUND Previous studies have investigated the role of botulinum neurotoxin (BoNT) in lateral epicondylalgia, with controversial results. We hypothesized that BoNT would be effective and safe for the treatment of lateral epicondylalgia. OBJECTIVE To investigate the effectiveness and safety of different doses of BoNT in participants with lateral epicondylalgia. METHODS PubMed, Embase, and Cochrane Library were searched up to August 27, 2022, for randomized controlled trials (RCTs) of BoNT treatment for epicondylalgia. The Cochrane risk of bias tool was used for quality assessment. A network meta-analysis and a trial sequential analysis (TSA) were conducted on pain, grip strength and adverse events. Meta-regression was applied for high heterogeneity comparisons. RESULTS We included 8 RCTs consisting of 448 participants. Four studies scored low risk of bias in all categories, whereas the other 4 studies had unclear risk only in the selection bias category. The network meta-analysis and TSA revealed that corticosteroid (standardized mean difference [SMD]: -1.32, 95% CI: -2.13; -0.50), high-dose BoNT (SMD -1.32, -2.04; -0.61), and low-dose BoNT (SMD -0.52, -0.93; -0.10), relieved pain significantly better than placebo for up to 7 to 10 weeks. High-dose BoNT demonstrated a significantly greater reduction in pain than low-dose BoNT for up to 7 to 10 weeks (SMD -0.81, -1.39; -0.22). Finally, after low-dose BoNT, younger participants (p = 0.023) and women (p = 0.012) showed more pain decrease than older individuals and men at 2 to 6 weeks. As for grip strength and adverse events, only grip strength after low-dose BoNT versus placebo (SMD -0.49, -0.88; -0.10) and corticosteroid (SMD -1.36, -2.15; -0.57) at 2 to 6 weeks reached significance after threshold adjustment in TSA. CONCLUSIONS Our meta-analysis confirmed the effectiveness of low-dose BoNT in the reduction of pain for lateral epicondylalgia. Further conclusions cannot be drawn due to insufficient available data.

Abstract
BACKGROUND Various botulinumtoxinA formulations are approved for glabellar lines treatment worldwide, including abobotulinumtoxinA (Dysport®). OBJECTIVES Assess abobotulinumtoxinA superiority versus placebo and non-inferiority versus active comparator (onabotulinumtoxinA; Botox®), for the treatment of Chinese patients with moderate/severe glabellar lines. METHODS Phase 3, randomized study (NCT02450526) comprising a double-blind (cycle 1) phase and an open-label (cycles 2-5) phase. Patients received abobotulinumtoxinA 50 units or matching placebo (5:1), active comparator (onabotulinumtoxinA 20 units) or matching placebo (5:1). In cycles 2-5, eligible patients were retreated with abobotulinumtoxinA only. Responders had glabellar lines of none/mild severity. PRIMARY ENDPOINT responder rates at cycle 1, day 29 at maximum frown with abobotulinumtoxinA versus placebo (for superiority; by investigator's live assessment [ILA] and subject's self-assessment [SSA]), and versus active comparator (for non-inferiority; by ILA). Treatment-emergent adverse events were recorded. RESULTS Overall, 520 patients were randomized. Superiority and non-inferiority, respectively, were demonstrated for abobotulinumtoxinA versus placebo (ILA, SSA; both p < 0.0001) and abobotulinumtoxinA versus active comparator. AbobotulinumtoxinA efficacy was maintained over open-label cycles; median time to onset of efficacy was 2.0 days. After 6 months, 17% of patients treated with abobotulinumtoxinA remained responders. AbobotulinumtoxinA was well-tolerated. Safety results were in line with the known profile of abobotulinumtoxinA; adverse events rate decreased with repeated treatment. CONCLUSIONS After a single injection, abobotulinumtoxinA demonstrated superiority versus placebo and non-inferiority versus onabotulinumtoxinA for the treatment of moderate-to-severe glabellar lines in Chinese patients. Multiple injections of abobotulinumtoxinA demonstrated efficacy and safety in the treatment of glabellar lines in Chinese patients.

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.

Abstract
Botulinum toxin treatment is the most common non-surgical cosmetic treatment. Although there are many available treatments using botulinum toxin, their effects are temporary and repeated injections are required. These frequent injections can trigger an immunological response. In addition, botulinum toxin acts as an antigen in the body; thus, its effect disappears progressively due to this immunological reaction, which may cause treatment failure. Active botulinum toxin consists of a core neurotoxin and complexing proteins, the exact effects of which remain unclear. However, the complexing proteins are closely related to the immune response and the formation of neutralizing antibodies. Since neutralizing antibodies can lead to treatment failure, their formation should be prevented. Furthermore, various methods of detecting neutralizing antibodies have been used to predict treatment failure.

Abstract
BACKGROUND Botulinum toxin type A (BontA) is the most frequent treatment for facial wrinkles, but its effectiveness and safety have not previously been assessed in a Cochrane Review. OBJECTIVES To assess the effects of all commercially available botulinum toxin type A products for the treatment of any type of facial wrinkles. SEARCH METHODS We searched the following databases up to May 2020: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA We included RCTs with over 50 participants, comparing BontA versus placebo, other types of BontA, or fillers (hyaluronic acid), for treating facial wrinkles in adults. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcomes were participant assessment of success and major adverse events (AEs) (eyelid ptosis, eyelid sensory disorder, strabismus). Secondary outcomes included physician assessment of success; proportion of participants with at least one AE and duration of treatment effect. We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS We included 65 RCTs, involving 14,919 randomised participants. Most participants were female, aged 18 to 65 years. All participants were outpatients (private office or day clinic). Study duration was between one week and one year. No studies were assessed as low risk of bias in all domains; the overall risk of bias was unclear for most studies. The most common comparator was placebo (36 studies). An active control was used in 19 studies. There were eight dose-ranging studies of onabotulinumtoxinA, and a small number of studies compared against fillers. Treatment was given in one cycle (54 studies), two cycles (three studies), or three or more cycles (eight studies). The treated regions were glabella (43 studies), crow's feet (seven studies), forehead (two studies), perioral (two studies), full face (one study), or more than two regions (nine studies). Most studies analysed moderate to severe wrinkles; mean duration of treatment was 20 weeks. The following results summarise the main comparisons, based on studies of one treatment cycle for the glabella. AEs were collected over the duration of these studies (over four to 24 weeks). Compared to placebo, onabotulinumtoxinA-20 U probably has a higher success rate when assessed by participants (risk ratio (RR) 19.45, 95% confidence interval (CI) 8.60 to 43.99; 575 participants; 4 studies; moderate-certainty evidence) or physicians (RR 17.10, 95% CI 10.07 to 29.05; 1339 participants; 7 studies; moderate-certainty evidence) at week four. Major AEs are probably higher with onabotulinumtoxinA-20 U (Peto OR 3.62, 95% CI 1.50 to 8.74; 1390 participants; 8 studies; moderate-certainty evidence), but there may be no difference in any AEs (RR 1.14, 95% CI 0.89 to 1.45; 1388 participants; 8 studies; low-certainty evidence). Compared to placebo, abobotulinumtoxinA-50 U has a higher participant-assessed success rate at week four (RR 21.22, 95% CI 7.40 to 60.56; 915 participants; 6 studies; high-certainty evidence); and probably has a higher physician-assessed success rate (RR 14.93, 95% CI 8.09 to 27.55; 1059 participants; 7 studies; moderate-certainty evidence). There are probably more major AEs with abobotulinumtoxinA-50 U (Peto OR 3.36, 95% CI 0.88 to 12.87; 1294 participants; 7 studies; moderate-certainty evidence). Any AE may be more common with abobotulinumtoxinA-50 U (RR 1.25, 95% CI 1.05 to 1.49; 1471 participants; 8 studies; low-certainty evidence). Compared to placebo, incobotulinumtoxinA-20 U probably has a higher participant-assessed success rate at week four (RR 66.57, 95% CI 13.50 to 328.28; 547 participants; 2 studies; moderate-certainty evidence), and physician-assessed success rate (RR 134.62, 95% CI 19.05 to 951.45; 547 participants; 2 studies; moderate-certainty evidence). Major AEs were not observed (547 participants; 2 studies; moderate-certainty evidence). There may be no difference between groups in any AEs (RR 1.17, 95% CI 0.90 to 1.53; 547 participants; 2 studies; low-certainty evidence). AbobotulinumtoxinA-50 U is no different to onabotulinumtoxinA-20 U in participant-assessed success rate (RR 1.00, 95% CI 0.92 to 1.08, 388 participants, 1 study, high-certainty evidence) and physician-assessed success rate (RR 1.01, 95% CI 0.95 to 1.06; 388 participants; 1 study; high-certainty evidence) at week four. Major AEs are probably more likely in the abobotulinumtoxinA-50 U group than the onabotulinumtoxinA-20 U group (Peto OR 2.65, 95% CI 0.77 to 9.09; 433 participants; 1 study; moderate-certainty evidence). There is probably no difference in any AE (RR 1.02, 95% CI 0.67 to 1.54; 492 participants; 2 studies; moderate-certainty evidence). IncobotulinumtoxinA-24 U may be no different to onabotulinumtoxinA-24 U in physician-assessed success rate at week four (RR 1.01, 95% CI 0.96 to 1.05; 381 participants; 1 study; low-certainty evidence) (participant assessment was not measured). One participant reported ptosis with onabotulinumtoxinA, but we are uncertain of the risk of AEs (Peto OR 0.02, 95% CI 0.00 to 1.77; 381 participants; 1 study; very low-certainty evidence). Compared to placebo, daxibotulinumtoxinA-40 U probably has a higher participant-assessed success rate (RR 21.10, 95% CI 11.31 to 39.34; 683 participants; 2 studies; moderate-certainty evidence) and physician-assessed success rate (RR 23.40, 95% CI 12.56 to 43.61; 683 participants; 2 studies; moderate-certainty evidence) at week four. Major AEs were not observed (716 participants; 2 studies; moderate-certainty evidence). There may be an increase in any AE with daxibotulinumtoxinA compared to placebo (RR 2.23, 95% CI 1.46 to 3.40; 716 participants; 2 studies; moderate-certainty evidence). Major AEs reported were mainly ptosis; BontA is also known to carry a risk of strabismus or eyelid sensory disorders. AUTHORS' CONCLUSIONS BontA treatment reduces wrinkles within four weeks of treatment, but probably increases risk of ptosis. We found several heterogeneous studies (different types or doses of BontA, number of cycles, and different facial regions) hindering meta-analyses. The certainty of the evidence for effectiveness outcomes was high, low or moderate; for AEs, very low to moderate. Future RCTs should compare the most common BontA (onabotulinumtoxinA, abobotulinumtoxinA, incobotulinumtoxinA, daxibotulinumtoxinA, prabotulinumtoxinA) and evaluate long-term outcomes. There is a lack of evidence about the effects of multiple cycles of BontA, frequency of major AEs, duration of effect, efficacy of recently-approved BontA and comparisons with other treatments.

Abstract
BACKGROUND Recently, the safety of a new botulinum toxin (HU-014) was confirmed through animal experiments. The evaluation of the efficacy and safety of this newly introduced botulinum toxin is required considering the risk of adverse events (AEs) and need for standardization before its universal use. OBJECTIVE The aim of this multicenter, double-blind, randomized, parallel, active-controlled phase III clinical trial was to investigate the noninferiority of HU-014 versus existing onabotulinumtoxin A for the treatment of moderate to severe glabellar lines. METHODS In total, 267 subjects were randomized to either the test (HU-014) or control (onabotulinumtoxin A) group. At the baseline and at weeks 4, 8, 12, and 16, investigator's live assessment, independent photographic assessment, subjects' improvement assessment, subjects' satisfaction assessment, and safety assessment were performed. RESULTS At week 4, the response rate was 90.15% and 92.31% in the test and control groups, respectively, as per investigator's live assessment while frowning, without a significant difference. Both groups also showed no significant differences in response rates in the other assessments. In addition, no serious AEs were reported. CONCLUSION HU-014 was noninferior to existing onabotulinumtoxin A in the treatment of glabellar lines at a 1:1 dose ratio, and both products were well tolerated.

Abstract
The desire to maintain youth as long as it possible in modern society, especially among women of working age, is primarily due to the desire to be in demand, well-groomed and attractive. Currently, there are 5 main methods that contribute to improving the condition of the skin of the face, namely: the method using professional cosmetics, chemical peels, mesotherapy, treatment with an injection of botulinum toxin type A (BTA) and intradermal implants based on hyaluronic acid.
The aim of the literature review was to analyze the latest scientific data on the possibility of botulinum therapy in cosmetology.
Wrinkles of open areas of the body (primarily on the face and in the decollete) have a negative effect on the emotional background and quality of life of women. In this regard, recently there has been a significant increase in demand for aesthetic medicine services, one of the areas of which is botulinum therapy (BT). Botulinum toxin type A (BTA) is a powerful neurotoxin that inhibits the release of acetylcholine in the neuromuscular junction. Injections of small doses of botulinum toxin type A into targeted mimic muscles cause their relaxation, which smoothes the underlying layer of the skin, thereby regressing mimic wrinkles. Today, according to officially approved indications, it is used in cosmetology, botulinum therapy is used to correct mimic wrinkles in the upper third of the face, drooping corners of the mouth, in the complex correction of the face oval, in the treatment of axillary and palmar hyperhidrosis. Blocking a tear mediator like acetylcholine, not only the presynaptic membranes of neuromuscular synapses are rich, but also many anatomical structures, such as glandular tissue (sweat, other glands, etc.). This commonality of the mechanism of action on various physiological processes in our body allows us to make an assumption about the great potential of botulinum therapy in the treatment of a number of diseases associated with impaired neuromuscular conduction.

Abstract
Recently launched esthetic botulinum toxin serotype A (BoNT/A) products include Nabota/Jeuveau, Meditoxin/Neuronox, and Botulax, which contain nontoxic accessory proteins and excipients. Clinical evidence supporting these formulations, including their purity and potential immunogenicity or their link to treatment failures, is limited. Any nonhuman protein, including nontoxin accessory proteins, can initiate immune reactions, especially if administered repeatedly, yet the issue of BoNT/A-induced immunogenicity is widely contested. However, there have been multiple reports of treatment failures and observations of BoNT/A-induced neutralizing antibodies. Compared with the purified formulation in Xeomin, these recently launched toxins contain higher total neurotoxin quantities, much of which is inactive and exposes patients to potentially immunogenic nontoxin proteins or inactive neurotoxins that increase their risk of developing treatment failure. Well-established products [especially abobotulinumtoxinA (Dysport), onabotulinumtoxinA (Botox) and Xeomin] are accompanied by comprehensive and long-ranging clinical evidence on safety and efficacy in esthetic facial indications, which still remains undisclosed for many of the recently introduced toxins. Clinicians need this information as patients will require repeated BoNT treatments and may be unnecessarily but cumulatively exposed to potential immunogens. To underscore the need for caution and further evidence, we review some of the issues surrounding BoNT/A-induced immunogenicity and antibody-induced treatment failures and argue that using highly purified toxins that do not negatively impact patient outcomes is a prudent clinical decision.

Abstract
INTRODUCTION Neuronox® has not yet been investigated for its efficacy and safety in the treatment of lateral canthal lines (LCL). METHODS This study was a randomized, double-blind, active drug controlled, multicenter, 16 week, Phase I/III study designed to determine the non-inferiority of Neuronox® compared to onabotulinumtoxin A (ONA) in the treatment of moderate to severe LCL. Thirty subjects in Phase I and 220 subjects in Phase III were randomized in a 1:1 ratio to receive a single treatment (24 U) of either Neuronox® or ONA. The primary endpoint of the Phase III study was the responder rate according to the proportion of subjects achieving Grade 0 (none) or 1 (mild) from 2 (moderate) or 3 (severe) in LCL severity at maximum smile as assessed by the investigators at Week 4. Additional efficacy endpoints and safety endpoints (adverse events) were also evaluated. RESULTS The primary endpoint was achieved as the proportion of responders was 83% for both Neuronox® and ONA, thus, supporting the non-inferiority of Neuronox® compare to ONA. The two groups also showed no statistical differences in safety analyses. CONCLUSION Treatment of moderate to severe LCL with Neuronox® was effective and well-tolerated.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinical outcomes of treatment of non-odontogenic atypical orofacial pain using botulinum toxin-A. METHODS This study involved seven patients (seven females, mean age 65.1 years) who had non-odontogenic orofacial pain (neuropathic pain and atypical orofacial pain) and visited the Seoul National University Bundang Hospital between 2015 and 2017. All medication therapies were preceded by botulinum toxin-A injections, followed by injections in the insignificant effects of medication therapies. Five of the seven patients received intraoral injections in the gingival vestibule or mucosa, while the remaining two received extraoral injections in the masseter and temporal muscle areas. RESULTS In five of the seven patients, pain after botulinum toxin-A injection was significantly reduced. Most of the patients who underwent surgery for dental implantation or facial nerve reconstruction recovered after injections. However, the pain did not disappear in two patients who reported experiencing persistent pain without any cause. CONCLUSIONS The use of botulinum toxin-A for the treatment of non-odontogenic neuropathic orofacial pain is clinically useful. It is more effective to administer botulinum toxin-A in combination with other medications and physical therapy to improve pain.

Abstract
Background Safety, efficacy, and time to onset of effect of botulinum toxin type A is of importance to persons who seek improvement in glabellar frown lines, but this has not been well studied. The aim of this study was to determine the safety, efficacy, and onset of action of a newly developed botulinum toxin type A (Nabota) for the treatment of glabellar frown lines. Methods This was a single-arm, open-label, and phase 4 clinical study. Forty-two subjects with glabellar lines were treated with five times of intramuscular injection of 0.1 mL (4 U/0.1 mL) for a total of 20 U of Nabota. Efficacy and safety were assessed at 2, 3, 4, 5, and 14 days. Efficacy was assessed by the investigator and it was defined as a 1-point change on a 4-point scale. Results Improvement in glabellar frown lines at maximum frown was observed in 85.4% of subjects 2 days after administration. Improvement in glabellar lines at rest was observed in 51.2% of subjects 2 days after administration, and the proportion of subjects showing improvement increased with time. No severe adverse events were recorded. Conclusion Onset of action was observed in the majority of subjects by 2 days after administration of Nabota. In addition, Nabota was found to be safe and effective for the treatment of glabellar frown lines.

Abstract
Botulinum toxin is a potentially deadly anaerobic bacterial toxin that acts by inhibiting release of acetylcholine at the neuromuscular junction, thereby inhibiting contraction of the exposed striated muscle. There are currently 4 botulinum toxin preparations approved by the US Food and Drug Administration (FDA): onabotulinumtoxin, abobotulinumtoxin, incobotulinumtoxin and rimabotulinumtoxin. While significant overlap exists, each product has unique properties and specifications, including dosing, diffusion, and storage. Extensive physician knowledge of facial anatomy, coupled with key differences of the various neurotoxin types, is essential for safe and successful treatments. The first article in this continuing medical education series reviews key characteristics of each neurotoxin, including new and upcoming agents, and provides an anatomic overview of the most commonly injected cosmetic sites.

Abstract
INTRODUCTION The pursuit of youth and beauty has undergone a resurgence of interest which is evidenced by increasing cosmetic procedures. Botulinum Toxin Type A (Botox) is one among the many procedures invented for facial rejuvenation which denervates certain muscles of facial expression responsible for facial wrinkles. It has been applied in the forehead, glabella, lateral canthal area and neck. In maxillofacial area hyperactive forehead wrinkles show sagging. AIM This study was aimed to clinically evaluate the efficacy of Botox injection in the elimination of hyperdynamic forehead wrinkles and the objectives were to compare pre-operative and post-operative improvement in the number of wrinkles, photographic grading and patient satisfaction responses after 1st week, 4th week and 16th week. MATERIALS AND METHODS A total of 10 patients were randomly included in the present study who were cooperative, motivated and aesthetically conscious with moderate to severe forehead wrinkles. Assessment was performed clinically, photographically (using standardized photographs) and patient satisfaction responses were recorded at 1st week, 4th week and 16th week. RESULTS The study showed a significant difference in the elimination of wrinkles at rest and in action when assessed at 1st week and 4th week and it was consistent at 16th week. The patient showed positive satisfaction response without ptosis of the upper eyelid. CONCLUSION Treatment with Botox is simple, safe and an effective modality for reduction of forehead wrinkles. It offers an alternative management in a cost-effective way when compared to surgical procedures.

Abstract
Background Cervical dystonia (CD) is a debilitating neurological disorder that may gravely affect a patient’s quality of life (QoL). Botulinum toxin treatment has been approved as a first-line treatment for this condition. This study aims to look at the efficacy and impact on the QoL of neu-botulinumtoxinA, a newer and cheaper botulinum toxin type A, in patients with CD. Methods This is a prospective, open-label, single-arm study. CD patients were recruited and evaluated for severity of CD using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), and for QoL using the Craniocervical Dystonia Questionnaire (CDQ-24), and the 36-item Short Form Health Survey questionnaire (SF-36) at baseline and 6 weeks after injection. Results Twenty patients were recruited. Significant improvement was shown in part 1 and total TWSTRS score and total CDQ-24 scores. Analysis of individual items of the TWSTRS scale showed significant improvement in rotation, duration of CD, and work ability. Significant improvements in the QoL were also seen in some items of the stigma, emotional wellbeing, and energy/fatigue domains of the CDQ-24 and SF-36 questionnaires. Discussion Neu-botulinumtoxinA is efficacious in treating CD symptoms and improving QoL of patients with CD. A larger, double-blinded study is needed to study the extent of improvements.

Abstract
BACKGROUND Three formulations of botulinum toxin are available for facial rhytides. It is unclear which formulation offers the greatest balance of benefits and harms. The objective of this study was to conduct a systematic review with meta-analyses to compare formulations of botulinum toxin for reduction of facial rhytides at the glabella. METHODS The authors' protocol was registered with the International Prospective Register of Systematic Reviews (CRD4201200377). A systematic literature search was performed identifying double-blind studies. The authors assessed 1-, 3-, and 4-month follow-up. The authors performed pairwise meta-analyses using random effects models to compare response rates among the three botulinum formulations and a network meta-analysis. RESULTS A total of 18 studies (3082 patients) were included. At 30-, 90-, and 120-day follow-up, all medications with available data showed statistically significantly increased treatment response versus placebo. Only high-dose onabotulinum toxin (compared to standard-dose onabotulinum toxin) offered additional benefit at 30 days. Exploratory analysis using network meta-analysis mostly suggested insufficient evidence of incremental benefits when comparing specific formulations. CONCLUSIONS Evidence supporting benefits versus placebo of the different formulations was clear over time. Comparisons between active formulations were rare and typically based on single trials of small to moderate sample size. The data suggest some gains with high-dose onabotulinum toxin (relative to standard dose), whereas exploratory indirect comparisons between active formulations were largely associated with inconclusive findings. Future studies should undertake head-to-head comparisons of the different formulations and ensure longer follow-up to best inform the accumulating evidence base.

Abstract
A novel botulinum neurotoxin type A (DWP450; Daewoong Pharmaceutical, Seoul, Korea) has recently been introduced for the treatment of facial wrinkles. The efficacy of this agent has previously been demonstrated in an in vivo study using an electrophysiological protocol in a rat model. To compare the efficacy and safety of DWP450 with onabotulinumtoxinA (OBoNT) for use in the treatment of glabellar lines, we performed a multicenter, double-blind, randomized, active-controlled trial comparing DWP450 and OBoNT (Allergan Inc., Irvine, CA, USA). A total of 268 subjects with moderate to severe glabellar lines were randomized at a 1:1 ratio. Each patient received treatment with 20 U of study medication. Maximum frown responder rates at week 4 were measured to analyze the primary efficacy endpoint. To evaluate secondary efficacy endpoints, response rates were measured at weeks 8, 12, and 16, at maximum frown and rest. Specifically, responder rates at both maximum frown and at rest were assessed based on clinical photography. Subject degree of satisfaction and self-assessed rate of response were also measured. Adverse events (AEs) were documented to evaluate safety. Responder rate by physician-rating severity at maximal contraction at week 4 was 93.89% in the DWP450 group and 88.64% in OBoNT group. As the lower limit of the 97.5% one-sided confidence interval (-1.53%) surpassed the -15% threshold, we determined that DWP450 was not inferior to OBoNT. For the secondary efficacy endpoint analyses, no significant differences were observed between the two groups for any variable at any point in time. The incidences of AEs were similar for the two groups. Most of AEs were considered mild. DWP450 and OBoNT were comparable in efficacy and safety in the treatment of glabellar lines.

Abstract
BACKGROUND Botulinum toxins have been widely used in cosmetic dermatology. Neurotoxin from the CBFC26 strain (NTC) is a recently developed botulinum toxin type A product manufactured through refined procedures. OBJECTIVE A double-blinded, randomized, multicentre-designed, phase III trial to investigate the non-inferiority of NTC to existing botulinum toxin A, onabotulinumtoxin A in the treatment of moderate to severe glabellar lines. METHODS A total of 272 subjects were randomized in a 1 : 1 ratio to receive 20 U of NTC or onabotulinumtoxin A. The primary endpoint was the response rate of physicians' assessment (PA) using the Facial Wrinkle Scale at week 4. The secondary endpoints included the response rate of PA at weeks 8, 12 and 16, and photographic assessment at weeks 4, 8, 12 and 16. Subjects' improvement assessment and subjective self-satisfaction levels were also investigated. RESULTS Response rates for maximum frown were 89.3% in the NTC group and 81.9% in the onabotulinumtoxin A group at week 4. NTC also resulted in comparable results for both the response rates of the other evaluation points and incidence of adverse events compared to those of onabotulinumtoxin A. In subjects' improvement assessment and photographic evaluations, NTC even demonstrated better results compared with onabotulinumtoxin A in the early phase after treatment. Analysis of these results strongly supports the non-inferiority of NTC to onabotulinumtoxin A in the efficacy and safety. CONCLUSION NTC is as effective as onabotulinumtoxin A in the treatment of glabellar lines, and both products were well tolerated.
