Abstract
Botulinum toxin type A (BoNT-A) injection patterns customized to each patient’s unique tremor characteristics produce better efficacy and lower adverse effects compared to the fixed-muscle-fixed-dose approach for Essential Tremor (ET) and Parkinson’s disease (PD) tremor therapy. This article outlined how a kinematic-based dosing method to standardize and customize BoNT-A injections for tremors was developed. Seven ET and eight PD participants with significant tremor reduction and minimal perceived weakness using optimized BoNT-A injections determined by clinical and kinematic guidance were retrospectively selected to develop the kinematic-based dosing method. BoNT-A dosages allocated per joint were paired to baseline tremor amplitudes per joint. The final kinematic-based dosing method was prospectively utilized to validate BoNT-A injection pattern selection without clinical/visual assessments in 31 ET and 47 PD participants with debilitating arm tremors (totaling 122 unique tremor patterns). Whole-arm kinematic tremor analysis was performed at baseline and 6-weeks post-injection. Correlation and linear regression analyses between baseline tremor amplitudes and the change in tremor amplitude 6-weeks post-injection, with BoNT-A dosages per joint, were performed. Injection patterns determined using clinical assessment and interpretation of kinematics produced significant associations between baseline tremor amplitudes and optimized BoNT-A dosages in all joints. The change in elbow tremor was only significantly associated with the elbow total dose as the change in the wrist and shoulder tremor amplitudes were not significantly associated with the wrist and shoulder dosages from the selected 15 ET and PD participants. Using the kinematic-based dosing method, significant associations between baseline tremor amplitudes and the change (6-weeks post-first treatment) in tremor at each joint with BoNT-A dosages for all joints was observed in all 78 ET and PD participants. The kinematic-based dosing method provided consistency in dose selection and subsequent tremor reduction and can be used to standardize tremor assessments for whole-arm tremor treatment planning.

Abstract
Recent cell-based and animal experiments have demonstrated an effective reduction in botulinum neurotoxin A (BoNT/A) by copper. Aim: We aimed to analyze whether the successful symptomatic BoNT/A treatment of patients with Wilson’s disease (WD) corresponds with unusually high doses per session. Among the 156 WD patients regularly seen at the outpatient department of the university hospital in Düsseldorf (Germany), only 6 patients had been treated with BoNT/A during the past 5 years. The laboratory findings, indications for BoNT treatment, preparations, and doses per session were extracted retrospectively from the charts. These parameters were compared with those of 13 other patients described in the literature. BoNT/A injection therapy is a rare (<4%) symptomatic treatment in WD, only necessary in exceptional cases, and is often applied only transiently. In those cases for which dose information was available, the dose per session and indication appear to be within usual limits. Despite the evidence that copper can interfere with the botulinum toxin in preclinical models, patients with WD do not require higher doses of the toxin than other patients with dystonia.

Abstract
There is extensive literature supporting the efficacy of botulinum toxin (BoNT-A) for the treatment of post-stroke spasticity, however, there remain gaps in the routine management of patients with post-stroke spasticity. A panel of 21 Italian experts was selected to participate in this web-based survey Delphi process to provide guidance that can support clinicians in the decision-making process. There was a broad consensus among physicians that BoNT-A intervention should be administered as soon as the spasticity interferes with the patients' clinical condition. Patients monitoring is needed over time, a follow-up of 4-6 weeks is considered necessary. Furthermore, physicians agreed that treatment should be offered irrespective of the duration of the spasticity. The Delphi consensus also stressed the importance of patient-centered goals in order to satisfy the clinical needs of the patient regardless of time of onset or duration of spasticity. The findings arising from this Delphi process provide insights into the unmet needs in managing post-stroke spasticity from the clinician's perspective and provides guidance for physicians for the utilization of BoNT-A for the treatment of post-stroke spasticity in daily practice.

Abstract
Parkinson's disease is the most common age-related motoric neurodegenerative disease. In addition to the cardinal motor symptoms of tremor, rigidity, bradykinesia, and postural instability, there are numerous non-motor symptoms as well. Among the non-motor symptoms, autonomic nervous system dysfunction is common. Autonomic symptoms associated with Parkinson's disease include sialorrhea, hyperhidrosis, gastrointestinal dysfunction, and urinary dysfunction. Botulinum neurotoxin has been shown to potentially improve these autonomic symptoms. In this review, the varied uses of botulinum neurotoxin for autonomic dysfunction in Parkinson's disease are discussed. This review also includes discussion of some additional indications for the use of botulinum neurotoxin in Parkinson's disease, including pain.

Abstract
AbobotulinumtoxinA (aboBoNT-A) has been used for various cosmetic purposes, including minimization of moderate to severe lines, or other cosmetic indications, in the face and neck. We carried out a systematic review to identify all relevant evidence on the treatment approaches and outcomes of aboBoNT-A as a cosmetic treatment of the middle and lower areas of the face, and the neck. Embase, MEDLINE, Cochrane Library, congress proceedings and review bibliographies were searched for relevant studies. Identified articles were screened against pre-specified eligibility criteria. Of 560 unique articles identified, 10 were included for data extraction (three observational studies, 1 randomized controlled trial [with two articles] and five non-randomized trials). The articles provided data on gummy/asymmetric smile (2), marionette lines (5), masseter muscle volume (2), nasal wrinkles (2), perioral wrinkles (3) and the platysma muscle (4). All articles reporting on efficacy of aboBoNT-A demonstrated positive results, including reduction of wrinkles (5), reduction of masseter muscle (2) and degree of gummy smile (1) compared with before treatment. No serious adverse events were reported and patient satisfaction was high. In conclusion, positive findings support further research of aboBoNT-A for the middle and lower areas of the face, and in the neck, which are largely unapproved indications.

Abstract
Botulinum toxin type A (BoNTA) is a powerful neurotoxin that inhibits acetylcholine release from presynaptic vesicles. The potency and safety profile of BoNTA grant the toxin vast therapeutic potential. It has been used off-label for a variety of dermatologic conditions. This review aims to analyze published literature regarding the benefits and risks of the off-label use of BoNTA beyond facial lines, including eccrine hidrocystomas, enlarged pores, keloids and hypertrophic scars, hidradenitis suppurativa, hyperhidrosis, masseter muscle hypertrophy, and salivary gland hypertrophy, among others. A MEDLINE search from January 2000 to December 2019 was conducted on the off-label uses of botulinum toxin in dermatology.

Abstract
Two randomized, placebo-controlled studies evaluated the pulmonary function safety of onabotulinumtoxinA (onabotA) for treatment of upper and/or lower limb spasticity. Patients with stable baseline respiratory status received one or two treatments with placebo, 240 U, or 360 U of onabotA. Pulmonary function tests, adverse events, and efficacy were measured at least every 6 weeks for 18 weeks (Study 1) or 30 weeks (Study 2). Study 1 enrolled 109 patients (n = 36–37/group) and Study 2 enrolled 155 patients (n = 48–54/group). Mean baseline forced vital capacity (FVC) was 76–78% of predicted per group in Study 1 and 71% of predicted per group in Study 2. In Study 1, change from baseline FVC values were significantly (p < 0.05) decreased vs. placebo at weeks 3 (240 U −57 mL vs. placebo +110 mL) and 12 (360 U −6 mL vs. +167 mL placebo). In Study 2, change from baseline FVC values were significantly decreased in the 360 U group vs. placebo at weeks 6 (−78 mL vs. +49 mL placebo), 13 (−60 mL vs. +119 mL placebo), 18 (−128 mL vs. +80 mL placebo), and 24 (−82 mL vs. +149 mL placebo). Individual pulmonary function-related adverse events were not correlated with PFT decreases. The most frequent pulmonary-related adverse events were nasopharyngitis (Study 1) and upper respiratory tract infection (Study 2). Ashworth scores were significantly improved at multiple time points in both studies. Injection of onabotA for spasticity in patients with decreased pulmonary function, at single and repeated doses of up to 360 U, was associated with small but statistically significant decreases in FVC or forced expiratory volume 1 s (FEV1) (>12% and 200 mL) that were subclinical and not correlated with any adverse clinical pulmonary events.

Abstract
Chemodenervation of cervical musculature using botulinum neurotoxin (BoNT) is established as the gold standard or treatment of choice for management of Cervical Dystonia (CD). The success of BoNT procedures is measured by improved symptomology while minimizing side effects and is dependent upon many factors including: clinical pattern recognition, identifying contributory muscles, BoNT dosage, and locating and safely injecting target muscles. In patients with CD, treatment of anterocollis (forward flexion of the neck) and anterocaput (anterocapitis) (forward flexion of the head) are inarguably challenging. The longus Colli (LoCol) and longus capitis (LoCap) muscles, two deep cervical spine and head flexor muscles, frequently contribute to these patterns. Localizing and safely injecting these muscles is particularly challenging owing to their deep location and the complex regional anatomy which includes critical neurovascular and other structures. Ultrasound (US) guidance provides direct visualization of the LoCol, LoCap, other cervical muscles and adjacent structures reducing the risks and side effects while improving the clinical outcome of BoNT for these conditions. The addition of electromyography (EMG) provides confirmation of muscle activity within the target muscle. Within this manuscript, we present a technical description of a novel US guided approach (combined with EMG) for BoNT injection into the LoCol and LoCap muscles for the management of anterocollis and anterocaput in patients with CD.

Abstract
To study the jitter parameters in the distant (DM) and the adjacent muscle (AM) after botulinum neurotoxin type A (BoNT/A) injection in 78 patients, jitter was measured by voluntary activation in DM (n = 43), and in AM (n = 35). Patients were receiving BoNT/A injections as a treatment for movement disorders. Mean age 65.1 years (DM) and 61.9 years (AM). The mean jitter was abnormal in 13.9% (maximum 41.4 µs) of DM, and 40% (maximum 43.7 µs) of AM. Impulse blocking was sparse. We found no correlation of the mean jitter to age, BoNT/A most recent injection (days/units), number of muscles injected, total BoNT/A units summated, number of total BoNT/A sessions, beta-blockers/calcium channel blockers use, and cases with local spread symptoms such as eyelid drop/difficulty swallowing. Maximum mean jitter (41.4/43.7 µs) for DM/AM occurred 61 and 131 days since the most recent BoNT/A, respectively. The far abnormal mean jitter (32.6/36.9 µs) occurred 229 and 313 days since the most recent BoNT/A. We suggested that jitter measurement can be done after BoNT/A in a given muscle other than the injected one, after 8 (DM) and 11 (AM) months, with reference >33 µs and >37 µs, respectively.

Abstract
This study describes the nerve entry point and intramuscular nerve branching of the rhomboid major and minor, providing essential information for improved performance of botulinum toxin injections and electromyography. A modified Sihler method was performed on the rhomboid major and minor muscles (10 specimens each). The nerve entry point and intramuscular arborization areas were identified in terms of the spinous processes and medial and lateral angles of the scapula. The nerve entry point for both the rhomboid major and minor was found in the middle muscular area between levels C7 and T1. The intramuscular neural distribution for the rhomboid minor had the largest arborization patterns in the medial and lateral sections between levels C7 and T1. The rhomboid major muscle had the largest arborization area in the middle section between levels T1 and T5. In conclusion, botulinum neurotoxin injection and electromyography should be administered in the medial and lateral sections of C7-T1 for the rhomboid minor and the middle section of T1-T7 for the rhomboid major. Injections in the middle section of C7-T1 should also be avoided to prevent mechanical injury to the nerve trunk. Clinicians can administer safe and effective treatments with botulinum toxin injections and other types of injections by following the methods in our study.

Abstract
(1) Background: In dystonia, the somatosensory temporal discrimination threshold (STDT) is abnormally increased at rest and higher and longer-lasting during movement execution in comparison with healthy subjects (HS), suggesting an abnormal sensorimotor integration. These abnormalities are thought to depend on abnormal proprioceptive input coming from dystonic muscles. Since Botulinum toxin-A (BT-A) reduces proprioceptive input in the injected muscles, our study investigated the effects of BT-A on STDT tested at rest and during voluntary movement execution in patients with focal dystonia. (2) Methods: We enrolled 35 patients with focal dystonia: 14 patients with cervical dystonia (CD), 11 patients with blepharospasm (BSP), and 10 patients with focal hand dystonia (FHD); and 12 age-matched HS. STDT tested by delivering paired stimuli was measured in all subjects at rest and during index finger abductions. (3) Results: Patients with dystonia had higher STDT values at rest and during movement execution than HS. While BT-A did not modify STDT at rest, it reduced the abnormal values of STDT during movement in CD and FHD patients, but not in BSP patients. (4) Conclusions: BT-A improved abnormal sensorimotor integration in CD and FHD, most likely by decreasing the overflow of proprioceptive signaling from muscle dystonic activity to the thalamus.

Abstract
OBJECTIVE This study examined how the effects of botulinum toxin therapy changed over time by sequential evaluation of clinical improvements in spasticity and contracture in 24 chronic-stage stroke patients on repeated botulinum toxin therapy who were receiving fewer rehabilitation interventions. METHODS Botulinum toxin injection was administered into the spastic muscle of the paralyzed upper or lower limb 5 times with at least 3-month intervals. Modified Ashworth Scale and range of motion were measured before and 2 weeks after each dose in the extremities to compare the first measurement value with subsequent values. Each predose value was also compared with the first predose value. RESULTS Compared with predose scores, Modified Ashworth Scale significantly improved in all flexors after 2 weeks from the first to fifth doses. Range of motion significantly improved in wrist dorsiflexion and ankle dorsiflexion. Comparison of values before each dose versus the first predose value showed significant improvement both in the Modified Ashworth Scale score of wrist flexors, finger flexors, and ankle planter flexors, and the range of motion of elbow extension, wrist dorsiflexion, and ankle dorsiflexion. CONCLUSION The comparison of predose values versus 2-week postdose values indicated that the effect of botulinum toxin formulation would not lessen after repeated injections with continuous improvements of Modified Ashworth Scale and range of motion. The comparison of predose values versus the first predose value also suggested that multiple injections of botulinum toxin formulation could be more effective in reducing spasticity and increasing the range of motion than a single injection.

Abstract
Background: It is important to study full-face aesthetic combination treatments to establish well-founded individual treatment plans. Objective: To evaluate clinical outcome and perception of treatment with either abobotulinumtoxinA (ABO) or hyaluronic acid (HA) filler followed by repeated combined treatment with ABO, HA filler, and Restylane® Skinboosters (RSB). Methods & Materials: This study was conducted at four sites in Sweden, France, and Brazil and included subjects aged 35-50 years with mild/moderate nasolabial folds and moderate/severe upper facial lines. Monotherapy was ≤125 s.U ABO in at least two upper facial indications with optional touch-up or ≤1 mL HA filler in nasolabial folds/cheeks. At months 6 and 12, both cohorts received ≤125 s.U. ABO in upper facial lines with optional touch-up, ≤2 mL HA filler in nasolabial folds/cheeks (and other facial areas as applicable), and ≤1 mL RSB. Assessments included global facial aesthetic appearance and improvement, first impression, perceived age, wrinkle severity, satisfaction questionnaires, and adverse events. Results: Repeated full-face treatment with ABO, HA filler, and RSB was associated with better aesthetic outcome and higher levels of satisfaction than treatment with ABO or HA filler alone. However, even modest volumes of HA filler achieved good aesthetic outcomes and high satisfaction. Treatment of several indications was well tolerated. Conclusion: Aesthetic improvement and subject satisfaction was high and increased with each treatment. All treatments were well tolerated. These data may be used as support when establishing individual treatment plans. J Drugs Dermatol. 2019;18(7):682-689.

Abstract
BACKGROUND Functional popliteal artery entrapment syndrome (FPAES) results from hypertrophied gastrocnemius, soleus, and/or plantaris muscles, without an identifiable anatomic abnormality. Historically, FPAES has been managed with surgical myotomy or myomectomy. Herein, we review the literature to evaluate the results of surgery along with a newer treatment (botulinum toxin A injection) for this rare form of claudication. METHODS A literature search in PubMed, Cochrane, and Ovid for studies reporting incidence and management of FPAES yielded 3391 publications; 2804 articles were excluded based on initially established exclusion criteria. Ultimately, data were extracted from six articles, from which the number of patients, demographic information, preoperative workup, surgical treatment details, follow-up imaging, and results of treatment were obtained. RESULTS A total of 133 patients were studied. Mean age was 26 years; 57% were female, and noninvasive testing revealed bilateral findings in 39%. Treatment involved surgical myotomy/myomectomy (98; five studies) and botulinum toxin injection (35; two studies). Adjunctive vascular reconstruction was performed in eight of the surgical cases. Patients with FPAES who underwent surgical management were evaluated subjectively for symptomatic improvement, and some patients had duplex ultrasounds in follow-up averaging 25.6 months. Three of 98 patients (3%) had recurrent symptoms, and seven (7%) underwent revision surgical procedures. Complications in the surgical management group included seroma/hematoma (4%, 4/98) and infection (2%, 2/98). For the botulinum toxin treatment group, improvement of symptoms was achieved in 66% of patients at an average follow-up time of ten months. Most patients treated with botulinum toxin did not undergo imaging in follow-up. No complications were reported. CONCLUSIONS This review suggests FPAES may be treated successfully with surgical myotomy/myomectomy plus adjunctive vascular reconstruction if necessary. Botulinum toxin A injection may be useful as a diagnostic and therapeutic measure for FPAES.

Abstract
BACKGROUND The principle of dynamic muscular activity affecting eyebrow height and shape is well known. We postulate that similarly, dynamics of the fronto-galea-occipital muscles affect forehead height. OBJECTIVES To present a forehead lift technique using Botulinum toxin injection and evaluate its clinical efficacy and safety. METHODS Twenty-nine female patients comprised the study group. Forty units of prepared abobutolinumtoxinA (Dysport, 10 U/0.05 mL) were injected into 4 points in the hair-bearing scalp, simulating the points of frontalis origin. The glabella and forehead regions were treated with 50 U each. Standard photographs and measurements were taken before and at 2 weeks following treatment. Forehead height was measured bilaterally drawing a vertical line from mid-pupil to frontal hairline (MPFH) and from medial canthus to frontal hairline (MCFH). We assessed outcome differences in patients with low vs high forehead (cutoff value 5.5 cm forehead height). RESULTS Mean age was 48 years (range, 29-66 years). Two weeks following treatment, mean frontal height had increased significantly in all measurement points (MCFH right: 4.1 ± 1.8 mm, MCFH left 4.4 ± 1.8 mm, MPFH right 4.4 ± 2.0 mm, MPFH left 4.7 ± 2.3 mm; P <0.001). Low forehead subgroup achieved significantly higher forehead lift compared with high forehead subgroup both in MCFH (6.9% ± 2.0% vs 5.3% ± 2.2%, P = 0.043) and MPFH (8.6% ± 2.5% vs 5.7% ± 2.6%, P = 0.008). No adverse events were documented in any participant. CONCLUSIONS Botulinum toxin type A injection into frontalis origin can effectively and safely extend forehead height in selected patients. The effect of this technique is greater on patients with low foreheads. LEVEL OF EVIDENCE 4

Abstract
BACKGROUND OnabotulinumtoxinA is approved for the prevention of headache in those with chronic migraine (CM); however, more clinical data on the risk-benefit profile for treatment beyond one year is desirable. METHODS The Chronic Migraine OnabotulinuMtoxinA Prolonged Efficacy open Label (COMPEL) Study ( ClinicalTrials.gov , NCT01516892) is an international, multicenter, open-label long-term prospective study. Adults with CM received 155 U of onabotulinumtoxinA (31 sites in a fixed-site, fixed-dose paradigm across 7 head/neck muscles) every 12 weeks (±7 days) for 9 treatment cycles (108 weeks). The primary outcome was headache day reductions at 108 weeks; secondary outcomes were headache day reductions at 60 weeks and change in the 6-item Headache Impact Test (HIT-6) score. Safety and tolerability were assessed by reviewing the frequency and nature of adverse events (AEs). AEs were determined at each visit through patient self-report, general non-directed and, for specific AEs, directed questioning, and physical examination. Subgroup analyses for safety and efficacy included, but were not limited to, patients with/without concomitant oral preventive treatment and acute medication overuse at baseline. RESULTS Enrolled patients (N = 716) were 18-73 years old and most were female (n = 607, 84.8%). At baseline, patients reported an average 22.0 (SD = 4.8) headache days per month. 52.1% of patients (n = 373) completed the study. By 60 and 108 weeks, a significant reduction in headache days (- 9.2 days and - 10.7 days, respectively, P < 0.0001) was observed. Significant improvements (P < 0.0001) in HIT-6 scores (- 7.1 point change at week 108) were also demonstrated. 131 patients (18.3%) reported ≥1 treatment-emergent adverse events; most frequently reported was neck pain (n = 29, 4.1%). One patient reported a serious treatment-related adverse event (rash). No deaths were reported. CONCLUSIONS The COMPEL Study provides additional clinical evidence for the consistency of the efficacy and for the long-term safety and tolerability of onabotulinumtoxinA for the prevention of headache in those with CM who have been treated with onabotulinumtoxinA every 12 weeks over 2 years (9 treatments) with the fixed-site, fixed-dose injection paradigm. TRIAL REGISTRATION Trial registration number: NCT01516892 . Name of registry: clinicaltrials.gov . Date of registration: January 20 2012. Date of enrollment of first patient: December 2011.

Abstract
Studies on children with hyperhidrosis are sparse. This retrospective study presents clinical data and quality of life, along with treatment effect and safety of botulinum toxin (BTX). Case reports from 366 children were included to capture the medical history of hyperhidrosis. The total median score of the Dermatology Life Quality Index before treatment was 11 for children aged 16-17 years and 12 for children younger than 16 years. The children described physical, psychosocial and consequence-related symptoms. More than 70% had multifocal hyperhidrosis. BTX-A and/or BTX-B were given to 323 children, 193 of whom received repeated treatments. The highest score in a 5-grade scale concerning treatment effect was reported by 176/193 children, i.e. their "sweating disappeared completely". No severe adverse events occurred. Focal and multifocal hyperhidrosis in children reduces quality of life considerably. Treatment with BTX-A and/or BTX-B has been performed with success.

Abstract
OnabotulinumtoxinA was approved for treatment of chronic migraine (CM) after publication of Phase 3 Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) trials. However, the PREEMPT trials lasted only up to 1 year. The main aim of our retrospective study was to evaluate whether a prolonged treatment of onabotulinumtoxinA (18 months, six quarterly cycles) will sustain or further improve the efficacy results and the quality of life achieved at 6 and 12 months. Patients were adults with CM with or without overuse of drugs, with at least six regularly repeat onabotulinumtoxinA treatments, administered according to the PREEMPT protocol. The outcomes were investigated after 6, 12, and 18 months of treatment with respect to baseline and with respect to each previous study time point. Headache days and hours, and dosage of headache medication taken with latency period, were collected from the patients daily. Quality of life was evaluated by means of the Migraine Disability Assessment (MIDAS) questionnaire. At each study time point, the proportion of responder patients with respect to baseline was evaluated. For all measures, the baseline data were referred to the previous month before starting. Forty-seven patients were evaluated. Our data show a decrease in the monthly headache days and hours, at each study evaluation, with respect to the previous one. They showed that beyond the first year, a statistically significant difference in the monthly days of headache compared at 18 vs. 12 months is observed. A significantly higher proportion of patients (with a response greater than 75% decrease from baseline in the frequency of headache days and hours) was observed at month 18 compared to month 12. The proportion of patients in MIDAS grade I increased over time, and a statistically significant improvement in MIDAS I score was obtained from month 12 to month 18. A positive modification in the consumption of analgesics over time was observed (p for trend <0.001). The mean acute drug latency strongly decreased over time. Our study confirmed that onabotulinumtoxinA is an effective treatment to reduce headache-related disability and improve patients' quality of life, highlighting that upon repeated administration, the therapy efficacy increases significantly and a progressive trend of "first-time response" is observed for the entire period under consideration.

Abstract
The efficacy and safety of botulinum toxin B (BTX-B) for treatment of Raynaud's phenomenon and digital ulcers in patients with systemic sclerosis was assessed. A total of 45 patients with systemic sclerosis who had Raynaud's phenomenon were blinded and divided randomly into 4 groups: a no-treatment control group, and 3 treatment groups, using 250, 1,000 or 2,000 international units (U) of BTX-B injections in the hand with more severe symptoms. Four weeks after injection, pain/numbness visual analogue scale scores and Raynaud's score in the groups treated with 1,000 and 2,000 U BTX-B were significantly lower than in the control group and the group treated with 250 U BTX-B. These beneficial effects were sustained until 16 weeks after the single injection. At 4 weeks after injection skin temperature recovery in the group treated with 2,000 U BTX-B was significantly improved. The numbers of digital ulcers in the groups treated with 1,000 and 2,000 U BTX-B were significantly lower than in the control group. In conclusion, 1,000 and 2,000 U BTX-B injections significantly suppressed the activity of Raynaud's phenomenon and digital ulcers in patients with SSc without serious adverse events.

Abstract
BACKGROUND Intramuscular injections of botulinum toxin A (BoNT-A) have been a cornerstone in the treatment of spasticity for the last 20 years. In Norway, the treatment is now offered to two out of three children with spastic cerebral palsy (CP). However, despite its common use, the evidence for its functional effects is limited and inconclusive. The objective of this study is to determine whether BoNT-A makes walking easier in children with CP. We hypothesize that injections with BoNT-A in the calf muscles will reduce energy cost during walking, improve walking capacity, increase habitual physical activity, reduce pain and improve self-perceived performance and satisfaction. METHODS/DESIGN This randomized, double-blinded, placebo-controlled, multicenter trial is conducted in a clinical setting involving three health regions in Norway. Ninety-six children with spastic CP, referred for single-level injections with BoNT-A in the calf muscles, will be invited to participate. Those who are enrolled will be randomized to receive either injections with BoNT-A (Botox®) or 0.9% saline in the calf muscles. Stratification according to age and study center will be made. The allocation ratio will be 1:1. Main inclusion criteria are (1) age 4 - 17.5 years, (2) Gross Motor Function Classification System levels I and II, (3) no BoNT-A injections in the lower limbs during the past 6 months and (4) no orthopedic surgery to the lower limbs during the past 2 years. The outcome measures will be made at baseline and 4, 12 (primary endpoint) and 24 weeks after injections. Primary outcome is change in energy cost during walking. Secondary outcomes are change in walking capacity, change in activity, perceived change in performance and satisfaction in mobility tasks, and pain. The primary analysis will use a linear mixed model to test for difference in change in the outcome measures between the groups. The study is approved by the Regional Ethical Committee and The Norwegian Medicines Agency. Recruitment started in September 2015. DISCUSSION The evaluation of effect is comprehensive and includes objective standardized tests and measures on both impairment and activity level. Results are to be expected by spring 2019.

Abstract
Botulinum neurotoxin A (BoNT-A), derived from Clostridium botulinum, has been used clinically for several diseases or syndrome including chronic migraine, spasticity, focal dystonia and other neuropathic pain. Chronic pelvic or bladder pain is the one of the core symptoms of bladder pain syndrome/interstitial cystitis (BPS/IC). However, in the field of urology, chronic bladder or pelvic pain is often difficult to eradicate by oral medications or bladder instillation therapy. We are looking for new treatment modality to improve bladder pain or associated urinary symptoms such as frequency and urgency for patients with BPS/IC. Recent studies investigating the mechanism of the antinociceptive effects of BoNT A suggest that it can inhibit the release of peripheral neurotransmitters and inflammatory mediators from sensory nerves. In this review, we will examine the evidence supporting the use of BoNTs in bladder pain from basic science models and review the clinical studies on therapeutic applications of BoNT for BPS/IC.

Abstract
Lateral canthal lines or crow's feet lines (CFL) may be treated with onabotulinumtoxinA. We identified several key concepts important to understanding the use of onabotulinumtoxinA for treatment of moderate-to-severe CFL. To contextualize and integrate data on the recommended dose and injection patterns of onabotulinumtoxinA for treatment of CFL, we summarized data from pivotal clinical studies in the development of onabotulinumtoxinA for treatment of CFL. Data from key studies of onabotulinumtoxinA for CFL are presented. The efficacy and safety of onabotulinumtoxinA treatment of moderate-to-severe CFL were evaluated in 2 randomized, controlled phase 3 studies comprising 1362 patients. The 24U total dose of onabotulinumtoxinA used in these studies was based on a phase 2 dose-ranging trial. Two injection patterns were available to investigators; each involved 3 injection sites per side in the lateral orbicularis oculi muscle. A cross-sectional analysis of photographs from the phase 3 trials provided detailed information on the frequency of 4 distinct CFL patterns. In the primary efficacy analysis for each phase 3 trial, CFL responder rates were significantly greater with onabotulinumtoxinA vs placebo at day 30 (P< .001). Eyelid edema (1%) was the only adverse event reported in ≥ 1% of patients receiving onabotulinumtoxinA, occurring more frequently with onabotulinumtoxinA than with placebo. The studies showed that onabotulinumtoxinA is effective and generally well-tolerated for CFL treatment. Additionally, 2 different injection patterns allow physicians to tailor treatment based on a patient's CFL pattern.

Abstract
While the facial rejuvenating effect of botulinum toxin type A is well known and widespread, its use in body and facial contouring is less common. We first describe its use for deliberate muscle volume reduction, and then document instances of unanticipated and undesirable muscle atrophy. Finally, we investigate the potential long-term adverse effects of botulinum toxin-induced muscle atrophy. Although the use of botulinum toxin type A in the cosmetic patient has been extensively studied, there are several questions yet to be addressed. Does prolonged botulinum toxin treatment increase its duration of action? What is the mechanism of muscle atrophy and what is the cause of its reversibility once treatment has stopped? We proceed to examine how prolonged chemodenervation with botulinum toxin can increase its duration of effect and potentially contribute to muscle atrophy. Instances of inadvertent botulinum toxin-induced atrophy are also described. These include the "hourglass deformity" secondary to botulinum toxin type A treatment for migraine headaches, and a patient with atrophy of multiple facial muscles from injections for hemifacial spasm. Numerous reports demonstrate that muscle atrophy after botulinum toxin type A treatment occurs and is both reversible and temporary, with current literature supporting the notion that repeated chemodenervation with botulinum toxin likely responsible for both therapeutic and incidental temporary muscle atrophy. Furthermore, duration of response may be increased with subsequent treatments, thus minimizing frequency of reinjection. Practitioners should be aware of the temporary and reversible effect of botulinum toxin-induced muscle atrophy and be prepared to reassure patients on this matter.

Abstract
Botulinum neurotoxin has revolutionized the treatment of spasticity and is now administered worldwide. There are currently three leading botulinum neurotoxin type A products available in the Western Hemisphere: onabotulinum toxin-A (ONA) Botox(®), abobotulinum toxin-A (ABO), Dysport(®), and incobotulinum toxin A (INCO, Xeomin(®)). Although the efficacies are similar, there is an intense debate regarding the comparability of various preparations. Here we will address the clinical issues of potency and conversion ratios, as well as safety issues such as toxin spread and immunogenicity, to provide guidance for BoNT-A use in clinical practice. INCO was shown to be as effective as ONA with a comparable adverse event profile when a clinical conversion ratio of 1:1 was used. The available clinical and preclinical data suggest that a conversion ratio ABO:ONA of 3:1-or even lower-could be appropriate for treating spasticity, cervical dystonia, and blepharospasm or hemifacial spasm. A higher conversion ratio may lead to an overdosing of ABO. While uncommon, distant spread may occur; however, several factors other than the pharmaceutical preparation are thought to affect spread. Finally, whereas the three products have similar efficacy when properly dosed, ABO has a better cost-efficacy profile.

Abstract
BACKGROUND Incobotulinumtoxin-A (Xeomin(®), Merz Pharmaceuticals, Sydney, New South Wales) is a formulation of botulinum neurotoxin type A that is free of complexing proteins. OBJECTIVE To assess the cost-effectiveness of incobotulinumtoxin-A administered with flexible treatment intervals compared to onabotulinumtoxin-A (Botox(®), Sydney, New South Wales) in blepharospasm and cervical dystonia from the perspective of Australian health care providers. METHODS A Markov state transition model was developed to perform a cost-utility analysis to compare the cost and health benefits of incobotulinumtoxin-A to that of onabotulinumtoxin-A. The cost-utility analysis compared incobotulinumtoxin-A treatment, given at minimum intervals of 6 weeks and maximum intervals of 20 weeks, with onabotulinumtoxin-A treatment, given at minimum intervals of 12 weeks and maximum intervals of 20 weeks. The Markov model consisted of three health states and followed patients in weekly cycles for 5 years. Only direct health care costs associated with the acquisition and administration of type A botulinum neurotoxins were included. Utility values were derived from a prospective, open-labeled cohort study. The primary outcome measure was the incremental cost per quality-adjusted life-year. Univariate and probabilistic sensitivity analyses were conducted. RESULTS Incobotulinumtoxin-A was cost-effective compared to onabotulinumtoxin-A in both blepharospasm and cervical dystonia, with an incremental cost/quality-adjusted life-year gained of A$ 25,588 and A$ 23,794, respectively. CONCLUSIONS Incobotulinumtoxin-A administered at flexible treatment intervals determined by the needs of the patient was found to be a cost-effective treatment option when compared to the administration of onabotulinumtoxin-A in the Australian health care system. The option to administer incobotulinumtoxin-A according to the needs of the patient resulted in patients experiencing symptoms for a fewer number of weeks compared to onabotulinumtoxin-A given at minimum 12-week intervals.

Abstract
OBJECTIVE Botulinum toxin injection has been applied for pain relief in various chronic pain syndromes. Recently, systematic review studies reported inconclusive effects of Botulinum toxin in myofascial pain management. The present study aimed to demonstrate the efficacy and safety of Botulinum toxin type A (BTxA) (Botox®) injection for pain reduction in myofascial trigger point (MTrP) of the upper trapezius muscle. MATERIAL AND METHOD Thirty-three patients with 48 MTrP on the upper trapezius muscles over three months with moderate to severe pain intensity diagnosed at physical medicine and rehabilitation outpatient department were recruited between December 2011 and March 2012. Eligible patients were blinded and randomly injected with single 0.2 ml (20 IU) of BTxA for 24 MTrP and 0.2 ml of 0.9% NaCl solution for 24 MTrP at the most tender trigger point on the upper trapezius muscle. All patients were advised for stretching exercise and ergonomic adaptation throughout the study. At 3- and 6-week after injections, visual analogue scale (VAS), the pressure pain threshold (PPT), and reported adverse effects were measured. RESULTS Both BTxA and control groups demonstrated statistically significant differences in VAS reduction and increased PPT after 3 weeks and 6 weeks compared with before treatment. There were no statistically significant differences in VAS reduction from baseline between the two groups at 3- and 6-week after treatment. A statistically significant difference in improvement of PPT from baseline and 6-week after BTxA injection compared with 0.9% NaCl group was shown (1.0 ± 0.9 and 0.5 ± 0.7, p = 0.036). There was mild degree side-effects that spontaneous resolved within one week in both groups without significant difference in percentage. No severe adverse effects were reported during the study. CONCLUSION The efficacy in VAS reduction of a single 20 IU of Botulinum toxin type A (Botox®) injection was not different from 0.9% NaCl for myofascial trigger point at the upper trapezius muscle. However Botulinum toxin type A (Botox®) showed statistically significant more increased in pressure pain threshold at 6-week after injection without severe adverse effects.

Abstract
Despite the extensive use of botulinum toxin A (BoNTA) in medical and cosmetic treatments, the potential spreading of BoNTA to surrounding tissues remains unknown. A patient with hemifacial paralysis upon blepharospasm treatment with low dose of BoNTA, prompted us to investigate the spreading effect. A randomised, double-blind study was conducted in which 5 healthy women (33-52 years) were treated with different doses of onabotulinum toxin unilaterally in the corrugator muscle. Parameters of efficacy and diffusion (CMAP; EMG and jitter analysis) in both glabellar and frontalis muscles were assessed at baseline, 2 and 4 weeks following BoNTA injection. CMAP of the treated glabellar muscles was reduced to approximately 40% in all dose groups. Additionally, contralateral CMAP reduction was observed in 3 of 5 subjects. These data confirm regional diffusion of BoNTA in facial muscle application, which raises question on the reliability of split-face models in BoNTA studies.

Abstract
The authors retrospectively evaluated the use of botulinum toxin injections to treat epiphora in children secondary to proximal obstruction of the nasolacrimal drainage system. Three patients (ages 8, 9, and 16 years) received botulinum toxin injections in the palpebral portion of the lacrimal gland. Two patients experienced symptomatic relief immediately following botulinum toxin injection. Both required subsequent injections, with an average symptomatic relief lasting 7 months. The only noted side effect was papillary conjunctivitis in one patient that resolved without treatment. The third patient was lost to follow-up. Although conjunctival dacryocystorhinostomy with Jones tube is the surgical procedure of choice for treating proximal lacrimal system obstruction, complication rates in children are high. Botulinum toxin injections provide a safe and effective alternative.

Abstract
Botulinum toxin (BTX) administered as an adjunct to other interventions for spasticity can act as a useful and effective therapeutic tool for treating patients disabled by spasticity. Presence of other non-reflex motor disorders (muscle stiffness, shortness, and contracture) can complicate the clinical course and disturb rehabilitative process of patients with spasticity. Treatment of spasticity using BTX can improve paralysis by correcting muscular imbalance that follows these diseases. In patients with chronic severe spasticity, we also have to address unique and difficult-to-treat clinical conditions such as abnormal posture and movement disorders. The effectiveness of BTX in treating some of these conditions is discussed. Because patients with neurological disabilities can show complex dysfunctions, specific functional limitations, goals, and expected outcomes of treatment should be evaluated and discussed with the patient, family members, and caregivers, prior to initiating BTX therapy. BTX therapy might improve not only care, passive function, but also motor functions in these patients by supplementing intensive rehabilitation with repetitive transcranial magnetic stimulation, transcranial direct-current stimulation, peripheral electrical stimulation, muscle stretching, and other rehabilitation strategies.

Abstract
PURPOSE This study used ultrasonography (US) to investigate the architectural changes in gastrocnemius muscles (GCM) after botulinum toxin injection (BoNT-A) in children with cerebral palsy (CP). MATERIALS AND METHODS Thirteen children with CP who received a BoNT-A injection into their GCM to treat equinus were recruited (9 males and 4 females). Architectural changes in both the medial and lateral heads of the GCM from a total of 20 legs were assessed using B-mode, real-time US. Muscle thickness (MT), fascicle length (FL), and fascicle angle (FA) were measured over the middle of the muscle belly in both a resting and neutral ankle position. Measures at 1 and 3 months after the injection were compared with baseline data taken before the injection. RESULTS The mean age of the subjects was 5.8 (±1.6) years. Spasticity was significantly reduced when measured by both the modified Tardieu scale and the modified Ashworth scale at 1 and 3 months after injection (p<0.05). The MT and FA of both the medial and lateral heads of the GCM were significantly reduced for both neutral and resting ankle positions at 1 and 3 months after the injection. The FL of both the medial and lateral heads of the GCM were significantly increased in a resting position (p<0.05), but not in a neutral position. CONCLUSION Our results demonstrated muscle architectural changes induced by BoNT-A injection. The functional significances of these changes were discussed.

Abstract
BACKGROUND Minimally invasive procedures are becoming increasingly popular because they require minimal downtime and are effective for achieving a more youthful appearance. The choice of needle for minimally invasive procedures can be a major factor in the patient's comfort level, which in turn affects the physician's comfort level. OBJECTIVES In this comparative study, the authors assessed levels of pain and bruising after participants were injected with 30-gauge or 33-gauge (G) microneedles, which are commonly used for minimally invasive injection procedures. METHODS Twenty healthy volunteers were recruited for this prospective study. Eight injection points (4 on each side of the face) were determined for each patient. All participants received injections of saline with both microneedles in a randomized, blinded fashion. Levels of pain and bruising were assessed and analyzed for significance. RESULTS The highest level of pain was in the malar region, and the lowest level was in the glabella. Although all pain scores were lower for the 33-G microneedle, the difference was significant only for the forehead. Because most minimally invasive procedures require multiple injections during the same sitting, the overall procedure was evaluated as well. Assessment of the multiple-injection process demonstrated a significant difference in pain level, favoring the 33-G needle. Although the difference in bruising was not statistically significant between the 2 needles, the degree of bruising was lower with the 33-G needle. CONCLUSIONS For procedures that involve multiple injections to the face (such as mesotherapy and injection of botulinum toxin A), thinner needles result in less pain, making the overall experience more comfortable for the patient and the physician. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVE To examine the efficacy of onabotulinumtoxin A (Botox) in the complex rehabilitation of patients with post-stroke spasticity of the leg in the early rehabilitation period of stroke. MATERIALS AND METHODS The study group comprised 31 patients in the early recovery period after stroke with the presence of equino-varus deformity of the foot with spasticity grade 3 or more (MAS). All patients received injections of onabotulinumtoxin A (Botox) in a total dose 400 ED as part of a comprehensive rehabilitation program. Dynamics of neurological status, spasticity, pain, function of walking and everyday activity was evaluated. RESULTS AND СONCLUSION: The high efficacy of botulinum neurotoxin type A was demonstrated. The drug reduced the severity of spasticity and discomfort in the leg and foot; promoted independent movement and increased walking speed of the patient.
