Abstract
BACKGROUND Chronic migraine (CM) is a disabling and hard-to-treat condition, associated with high disability and high cost. Among the preventive treatments, botulinum toxin A (BoNT-a) and monoclonal antibodies against the calcitonin gene-related protein (anti-CGRP mAbs) are the only disease-specific ones. The assessment of the disease burden is complex, and among others, tools such as the allodynia symptoms checklist (ASC-12) and headache impact test (HIT-6) are very useful. This exploratory study analysed the impact of these two therapies on migraine burden. METHODS The RAMO study was a multicentre, observational, retrospective investigation conducted in two headache centres: the Fondazione IRCCS Istituto Neurologico Carlo Besta (Milan) and the Fondazione Policlinico Campus Bio-Medico (Rome). This study involved patients with chronic migraine treated with mAbs or BoNT-A. We conducted a subgroup exploratory analysis on HIT-6 and ASC-12 scores in the two groups. The Wilcoxon rank-sum test, Fisher's exact test, and ANOVA were performed. RESULTS Of 126 patients, 36 on mAbs and 90 on BoNT-A had at least one available follow-up. mAbs resulted in a mean reduction of -11.1 and -11.4 points, respectively, in the HIT-6 at 6 and 12 months, while BoNT-A was reduced -3.2 and -3.6 points, respectively; the mAbs arm resulted in mean reductions in ASC-12 at 6 and 12 months of follow-up of -5.2 and -6.0 points, respectively, while BoNT-A showed lesser mean changes of -0.5 and -0.9 points, respectively. The adjusted analysis confirmed our results. CONCLUSIONS In this exploratory analysis, anti-CGRP mAbs showed superior effectiveness for HIT-6 and ASC12 compared to BoNT-A. Reductions in terms of month headache days (MHD), migraine disability assessment test (MIDAS), and migraine acute medications (MAM) were clinically relevant for both treatments.

Abstract
BACKGROUND Manifestations of OAB can considerably diminish the quality of life. Botulinum toxin has emerged as a valuable treatment option in diseases whose symptoms cannot be controlled adequately with other available therapies. The aim of the present study was to compare the subjective quality of life of patients with OAB before the injection of botulinum toxin and three and six months after the intervention. METHODS This study was based on a diagnostic survey with three validated questionnaires, ICIQ-OAB, ICIQ-OABqol, and ICIQ-LUTSqol, and an additional questionnaire developed by the authors to collect sociodemographic characteristics and selected medical data. RESULTS This study demonstrated significant differences between pre-treatment scores and those at three and six months post injection. At three and six months after the intervention, mean scores for all three instruments (ICIQ-OAB, ICIQ-OABqol, ICIQ-LUTSqol) were significantly lower than the respective pre-treatment values, implying a significant attenuation of OAB symptoms and their lower impact on the quality of life. However, the severity of OAB symptoms and their impact on the quality of life at six months post intervention were significantly higher than at three months, except for the social interaction domain. CONCLUSIONS Botulinum toxin is an effective treatment for OAB.

Abstract
PURPOSE OnabotulinumtoxinA is an approved treatment for neurogenic detrusor overactivity in adults inadequately managed with anticholinergics, and more recently was approved in children on the basis of a phase 3, 48-week, single-treatment study (NCT01852045). Given the paucity of long-term pediatric data, we report on the continued safety in these patients after repeated onabotulinumtoxinA treatment. MATERIALS AND METHODS This was a multicenter, double-blind, repeat-treatment extension study (NCT01852058) in patients who entered from the preceding single-treatment study. Data were integrated across both studies. All patients (5-17 years) used clean intermittent catheterization and could receive dose escalations based on response to preceding treatment (50 U, 100 U, or 200 U onabotulinumtoxinA [not to exceed 6 U/kg]). RESULTS Overall, 95, 90, 55, and 11 patients received 1, 2, 3, and 4 treatments with onabotulinumtoxinA, respectively, and median (quartiles) duration of follow-up was 82 (65, 94) weeks. The safety profile was similar across doses and after repeat treatments. The most common treatment-emergent adverse event during cycles 1, 2, and 3 was urinary tract infection (31%, 34%, 22%). Three serious treatment-emergent adverse events related to study treatment (3/95; 3.2%) were reported during the study, which were all cases of urinary tract infection. Annualized urinary tract infection rates post-treatment were similar to pre-screening rates. There were no cases of autonomic dysreflexia, neutralizing antibodies, and treatment-emergent adverse events related to distant spread of toxin. CONCLUSIONS OnabotulinumtoxinA continued to be well tolerated after repeated treatments in pediatric neurogenic detrusor overactivity patients with similar safety profiles across dose groups. Treatment-emergent adverse events were primarily urological with no new safety concerns.

Abstract
Background Onabotulinum toxin A (OnA) is a well-tolerated and effective treatment for chronic migraine (CM). However, based on research indications that incobotulinum toxin A (InA) would be equally effective, a Veterans' Health Administration Medical Center mandated a 2-year trial of InA as more cost-effective alternative to OnA. Although InA is used for many similar indications as OnA, it is not Food and Drug Administration approved for treating CM, and complications occurred in several patients with CM following this treatment change. We conducted this retrospective analysis to evaluate differences in the efficacy of OnA and InA and identify the reasons for the adverse effects of InA in some of these patients. Methods We performed a retrospective review of 42 patients who had been effectively treated with OnA and were then switched to InA. The differences between treatment responses to OnA and InA were assessed through the evaluation of pain on injection, number of headache days, and duration of action. Patients received injections at 10- to 13-week intervals. Those who reported excessive pain on injection of InA were switched back to OnA. Findings Severe burning pain on injection was reported by 16 (38%) patients for InA only and by 1 (2%) patient for both InA and OnA. Neither migraine suppression nor the duration of effect was significantly different between OnA and InA. Conclusions Reformulation of InA with a pH-buffered solution may eliminate the difference in pain on injection. InA would then be a good alternative to OnA for treating CM.

Abstract
OBJECTIVE Treating voiding dysfunction without anatomical obstructions is challenging. Urethral onabotulinum toxin A (BoNT-A) is used in treating voiding dysfunction; however, the success rate varies widely, and patients may not be satisfied with the treatment outcome. This study compared the efficacy of the urethral BoNT-A injection between patients with different non-spinal cord injury (SCI) voiding dysfunctions. MATERIALS AND METHODS This study retrospectively analyzed patients with refractory voiding dysfunction, including detrusor underactivity (DU), dysfunctional voiding (DV), and poor relaxation of the external sphincter (PRES) who received the urethral sphincter 100 U BoNT-A injection. The treatment outcomes were assessed via a global response assessment (GRA) one month after treatment. Baseline and follow-up videourodynamic study (VUDS) parameters were also compared. RESULTS Totally, 161 patients (60 with DU, 77 with DV, and 24 with PRES) with a mean age of 58.8 ± 20.2 were enrolled, of which 62.1% had a good response (GRA ≥ 2) after urethral BoNT-A injection. DV patients had a higher success rate (76.6%) than DU (50%) and PRES (45.8%) patients (p = 0.002). A diagnosis of DV, higher voided volume and recurrent urinary tract infection were predictors of a good treatment response, while the cervical cancer status post-radical surgery predicted a poor response. Receiver operating characteristic (ROC) curve analyses identified PVR > 250 mL as a negative predictor (p = 0.008) in DU patients. CONCLUSIONS The urethral BoNT-A injection provides a satisfactory success rate for non-SCI voiding dysfunction. Patients with DV benefit most from both subjective and objective parameters. Approximately 50% of patients with DU and PRES also had a fair response. PVR > 250 mL was a negative predictor in DU patients.

Abstract
The high percentage of treatment failures seen in patients with bladder pain syndrome/interstitial cystitis (BPS/IC) managed conservatively frequently demands invasive treatment options. We aimed to evaluate the long-term efficacy and adverse events of intratrigonal botulinum toxin injection in such circumstances, as well as to determine possible predictors of response to toxin treatment. A retrospective cohort study included 47 female BPS/IC patients treated with onabotulinum toxin A (OnabotA) in a tertiary hospital between the years 2009 and 2022. All patients received 100 U of OnabotA in ten injections limited to the trigonal area. Patients were divided into three groups based on their treatment response as responders, non-responders and lost to follow-up due to non-medical reasons. The clinical and surgical records of the individuals were retrieved, including the 10-point visual analogue scale (VAS), the number of treatments, the time between injections, and the age at the first injection. A total of 25 patients (>50% of the cohort) were long-term responders, but none of the evaluated parameters was a predictor for this circumstance: age, pain intensity, or duration of improvement following the injection. The time between injections was stable (around 1 year). No severe adverse events were registered. The intratrigonal injection of botulinum toxin in patients with BPS/IC was an effective and safe long-term treatment for patients' refractory to conservative forms of treatment. Age, basal pain intensity, and time to injection request did not predict long-term response to OnaBotA.

Abstract
OBJECTIVES The aim of the present study was to compare the subjective quality of life in patients with overactive bladder (OAB) prior to intravesical botulinum toxin injection and three and six months thereafter. MATERIAL AND METHODS The study included 50 women diagnosed with OAB refractory to oral pharmacotherapy. The respondents completed four questionnaires, ICIQ-OAB, ICIQ-OABqol, ICIQ-LUTSqol and a dedicated clinicodemographic survey. RESULTS Intravesical injection of botulinum toxin A contributed to the attenuation of OAB-related ailments and resultant improvement of the quality of life. The ICIQ-OAB scores at three and six months post-injection were significantly lower than at the baseline (p < 0.001), implying that the treatment reduced the severity of OAB manifestations. OAB ailments had, without a doubt, a detrimental effect on the quality of life, as shown by high ICIQ-OABqol and ICIQ-LUTSqol scores before the treatment. Administration of botulinum toxin A was associated with a significant decrease in scores for all domains of the ICIQ-OABqol and ICIQ-LUTSqol scales (p < 0.001). CONCLUSIONS Botulinum toxin is an effective treatment option in patients with OAB who failed to respond to anticholinergic therapy. Botulinum toxin injections contributed to a significant improvement in the quality of life during a six-month follow-up.

Abstract
We conducted a phase IV, pre/post multi-center study to evaluate the efficacy and safety of intradetrusor onabotulinumtoxinA injection in patients with neurogenic detrusor overactivity (NDO, n = 119) or overactive bladder (OAB, n = 215). Patients received either 200U (i.e., NDO) and 100U (i.e., OAB) of onabotulinumtoxinA injection into the bladder, respectively. The primary endpoint for all patients was the change in the PPBC questionnaire score at week 4 and week 12 post-treatment compared with baseline. The secondary endpoints were the changes in subjective measures (i.e., questionnaires: NBSS for patients with NDO and OABSS for those with OAB) at week 4 and week 12 post-treatment compared with baseline. Adverse events included symptomatic UTI, de novo AUR, gross hematuria and PVR > 350mL were recorded. The results showed that compared with baseline, PPBC (3.4 versus 2.4 and 2.1, p < 0.001) and NBSS (35.4 versus 20.4 and 18.1, p < 0.001) were significantly improved at 4 weeks and 12 weeks in NDO patients. In addition, compared with baseline, PPBC (3.5 versus 2.3 and 2.0, p < 0.001) and OABSS (9.1 versus 6.2 and 5.7, p < 0.001) were significantly improved at 4 weeks and 12 weeks in OAB patients. Eight (6.7%) had symptomatic UTI and 5 (4.2%) had de novo AUR in NDO patients. Twenty (9.3%) had symptomatic UTI but no de novo AUR in OAB patients. In conclusion, we found that intradetrusor onabotulinumtoxinA injections were safe and improved subjective measures related to NDO or OAB in our cohort.

Abstract
INTRODUCTION Neurogenic overactive bladder is a main feature of human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis. We successfully performed intravesical onabotulinumtoxinA therapy for refractory neurogenic overactive bladder due to human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis. CASE PRESENTATION We retrospectively reviewed four neurogenic overactive bladder patients with human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis who underwent bladder wall injections of onabotulinumtoxinA from April to October 2020. All patients were female. Their median age was 66 (range, 63-71) years. They were previously treated with β3-adrenergic receptor agonists or anticholinergic drugs alone or in combination for ≥12 weeks. However, insufficient results were obtained. After 4 weeks of intravesical onabotulinumtoxinA therapy, overactive bladder symptoms improved and maximum cystometric capacity increased in all cases. CONCLUSION Intravesical onabotulinumtoxinA therapy may be useful for treating refractory overactive bladder due to human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis.

Abstract
CHARGE syndrome is a genetic disorder that affects multiple organ and sensory systems. Cranial nerve involvement is one of the key clinical diagnostic criteria. We present the case of an 8-year-old girl with CHARGE syndrome, associated right-sided facial palsy, and chronic severe migraines, that were intractable to medical treatment. At age 6, onabotulinum toxin A was used to weaken the contralateral non-paralyzed side of her face to address her stigmatizing asymmetry. Onabotulinum toxin A chemodenervation was performed on the left lower lip depressors to relax the muscles and improve left lower lip position. Coincidentally, it was noted that with these treatments, migraine symptoms resolved. As the chemodenervation subsided over the next 3-4 months, the severe migraines returned. Continued treatment with onabotulinum toxin A injections every 3 months has resulted in ongoing improvements in facial symmetry and migraine control. Onabotulinum toxin A is a well-known treatment of chronic migraine. Injections are usually directed to the occipitalis, frontalis, and corrugator muscles. The literature has no reports of injections to the lower lip depressors as a useful therapy for migraine, making the results from this case unique.

Abstract
Background/objective Nummular headache (NH) is a primary headache disorder characterised by intermittent or continuous scalp pain, affecting a small circumscribed area of the scalp. As there are limited data in the literature on NH, we conducted this review to evaluate demographic characteristics and factors associated with complete resolution of the headache, and effectiveness of treatment options. Methods We performed a systematic review of cases reported through PubMed database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and 'nummular headache', 'coin-shaped headache' and 'coin-shaped cephalalgia' keywords. Analysis was performed by using χ2 test and Wilcoxon rank-sum test. For individual interventions, the response rate (RR%) of the treatment was calculated. Results We analysed a total of 110 NH cases, with median age 47 years and age of pain onset 42 years. Median duration to make correct diagnosis was 18 months after first attack. The median intensity of each attack was 5/10 on verbal rating scale over 4 cm diameter with duration of attack <30 min. Patients with NH had median three attacks per day with frequency of 9.5 days per month. 40 (57.97%) patients had complete resolution of the headache after treatment. Patients with complete resolution were younger, more likely to be female, and were more likely to have diagnosis within year. Patients with complete resolution more likely to have received treatment with onabotulinum toxin A (botulinum toxin type A (BoNT-A)), and gabapentin compared with patients without complete resolution. Most effective interventions were gabapentin (n=34; RR=67.7%), non-steroidal anti-inflammatory drugs (NSAIDs) (n=32; RR=65.6%), BoNT-A (n=12; RR=100%) and tricyclic antidepressant (n=9; RR=44.4%). Conclusion Younger patients, female sex and early diagnosis were associated with complete resolution. NSAIDs, gabapentin and BoNT-A were most commonly used medications, with significant RRs.

Abstract
BACKGROUND The classic symptoms of Frey syndrome are gustatory sweating and flushing. Aims of the study were to describe prevalenceand severity of typical and atypical presentations of the disorder and to assess the effects of botulinum neurotoxin A (BoNT-A) therapy in patients with Frey syndrome after parotidectomy. METHODS In this prospective, observational study on 18 patients, we assessed symptom severity before therapy, after 15 days, 1, 3 and 6 months' follow-up with the sweating-flushing-itch-paresthesia-pain (SFIPP) Frey scale specifically designed by the authors themselves for this study. RESULTS Before BoNT-A injection, all patients (100%) complained gustatory sweating, 80% paresthesia, 77% gustatory flushing, 60% pain and 60% gustatory itch. The SFIPP-Frey overall score and the symptom-specific ones decreased significantly at each post-therapy control. CONCLUSIONS The prevalence of "unusual" manifestations is not negligible. BoNT-A improves symptoms severity. The SFIPP-Frey scale may be useful to assess symptoms and to monitor post-therapy outcomes.

Abstract
This article will describe facial asymmetry secondary to facial nerve paralysis (FNP), and review current concepts, guidelines, and future trends. Despite the increasing use of botulinum toxin (BoNTA) in treating FNP, ideal dosage, timing, and additional therapies are not unequivocally established. Facial asymmetry significantly impacts quality of life (QOL) by strongly affecting self-perception and social interactions; injectables may mediate great clinical improvement. This article provides practical guidelines for the use of BoNTA and provides schemes for accurate assessment and documentation. A systematic, stepwise approach is recommended with methodical assessment, meticulous placement, conservative dosage, and careful follow-up. Future trends include the potential use of newly developed toxins, muscle modification with fillers, improved imaging techniques, and targeted QOL studies. Hopefully, a growing number of aesthetic injectors may become technically proficient and join multidisciplinary teams for managing FNP.

Abstract
OBJECTIVE: Botulinum toxin (BTX) A has different biological activities, including anti-inflammatory and antipruritic behavior. Studies on humans and animals have shown that BTX is efficient in treating itch caused by histamine, lichen simplex chronicus, psoriasis, rosacea, allergic rhinitis, and scar avoidance. OBJECTIVE: This study sought to assess the impact of BTX-A in patients with atopic dermatitis using scores of SCORAD and to identify parameters linked to greater improvements. METHODS: This was a prospective, intrapatient, left-to-right, randomized, placebo-controlled study of BTX-A for the treatment of atopic dermatitis. The study included 26 patients with atopic dermatitis (12 males and 14 females) with an average age of 37.8 years. Responses to therapy were assessed using SCORAD, Dermatology Quality of Life Index (DLQI), and the worldwide clinical reaction score evaluation. RESULTS: Mean SCORAD values dropped from 50.5 to 11 points (p<0.001); meanwhile, 64.1 percent of patients reported an excellent response, including 78.9 percent of patients with severe AD. The DLQI score fell by 10.15 points (43.5%) in patients treated with BTX-A. A statistically significant reduction in SCORAD and DLQI scores occurred relative to in the placebo group (p<0.001). CONCLUSION: Based on the results of this study, BTX-A appears to be a safe and effective therapy for atopic dermatitis of all grades (mild, moderate, and severe). However, BTX-A appears to be best suited for patients with severe atopic dermatitis.

Abstract
BACKGROUND Botulinum neurotoxin therapy (BoNT) is a powerful tool for treating many neurologic disorders. The U.S. Food and Drug Administration (FDA)-approved maximum onabotulinum toxin A (OnaA) dose is 400 units (U) per visit, but higher doses are commonly necessary, particularly when treating multiple body regions. METHODS We collected demographics, OnaA dose, body regions injected and indications, patient-reported efficacy via 7-point Clinical Global Impression Scale (CGIS), and duration of benefit. RESULTS Sixty-eight patients were identified receiving OnaA >400 U/session. Dystonia (n = 44) and spasticity (n = 24) were the most common indications for high-dose OnaA. Mean duration of benefit was 9 weeks (standard deviation [SD] 3). More than 70% of patients self-reported "very much improved" or "much improved" at 6 month, 1 year, and last visit. No serious adverse effects were reported. DISCUSSION The majority of patients tolerated >400 U OnaA with continued benefit. OnaA doses >400 U may be safe and effective in appropriate patients.

Abstract
Introduction Onabotulinum toxin A (OnabotA) cyclic treatment is approved for the prophylactic treatment of chronic migraine (CM), a highly disabling disorder. Although treatment response varies among patients, current guidelines suggest to stop treatment after cycle 2 if no response is achieved. This prospective study aimed to define, in real-life setting, the evolution of the response to OnabotA over five cycles of treatment among patients non-responding to cycle 1. The results of this study might help in decision-making, in particular whether prosecuting OnabotA further or not, when facing a patient not responding to cycle 1. Methods Patients failing to respond at cycle 1 were recruited to complete five cycles. Key outcomes were: (i) a ≥50% reduction in headache days, (ii) a ≥50% reduction in total cumulative hours of headache on headache days and (iii) a ≥5-point improvement in Headache Impact Test-6 (HIT-6) scores. Results Overall, 56 patients were included. Mean age was 45.7 years (female 83.9%). Severe (≥60) HIT-6 score was reported at baseline by 95.8% of patients. Responders (headache days reduction of more than 50%) progressively increased cycle after cycle, doubling from cycle 2 to cycle 5 (from 27 to 48%). In addition, patients regressed from CM to episodic migraine moving on with each cycle, with 78% of them reaching less than nine migraine days/month after cycle 5. The headache days per month decreased significantly from cycle 1 to cycle 5 (overall from 23.3 ± 5.7 to 9.2 ± 3.6; p < 0.001). During 12 months (5 cycles), migraine days per month progressively abated (from 18.5 to 8.7; p < 0.001), days with symptomatic medications intake/month consistently decreased (from 17.4 to 8.1; p < 0.001), and mean HIT-6 score lowered (from 72.4 ± 5.7 to 50.2 ± 4.3; p < 0.001). Conclusion The positive effect of OnabotA treatment spreads over the course of the treatment and might also manifest late in treatment course among patients with no benefit after the first two cycles. Thus, the results of this real-life study suggest to extend OnabotA treatment further, beyond cycle 2, to avoid premature withdrawal in patients who would have become responders at cycle 3, 4, or 5.

Abstract
Discovered by serendipity, onabotulinum toxin A (BoNT-A) is the only US Food and Drug Administration-approved treatment for the prevention of chronic migraine (CM), one of the most disabling and burdensome human conditions. Its efficacy, safety and tolerability, proved by the largest and longest migraine therapeutic trial (the Phase III Research Evaluating Migraine Prophylaxis Therapy program [PREEMPT]), have been replicated by various real-life studies also in the presence of medication overuse. The benefit of BoNT-A prophylaxis is likely due to its ability to counteract peripheral and central nociceptive sensitization through reversible chemical denervation of pericranial sensitive afferents. Its efficacy increases considerably over time during long-term treatments, significantly varying among patients. The present review focuses on the state-of-the art of current knowledge on putative instrumental, biochemical and clinical predictors of BoNT-A responsiveness, outlining the need for a thorough characterization of the full phenotypic migraine picture when trying to predict good responders. Available evidence suggests that disentangling the BoNT-A responsiveness puzzle requires 1) a reappraisal of easy-obtainable clinical details (eg, site and quality of pain, presence of cranial autonomic symptoms), 2) a proper stratification of patients with CM according to their headache frequency, 3) the evaluation of potential synergistic effects of concomitant prophylaxis/treatment and 4) a detailed assessment of modifiable risk factors evolution during treatment.

Abstract
OBJECTIVE The aim of this study was to test the addition of methylene blue (MB) to onabotulinum toxin A (BTX-A) solution in overactive bladder (OAB) treatment, as a means of facilitating observation of the injection site and assessing the distribution of the drug under the bladder mucosa during injection. Pharmacological interactions between BTX-A and MB were also evaluated. MATERIALS AND METHODS The study was conducted between December 2014 and April 2016 on 30 patients: six males and 24 females (median age 57.7, range 23-80 years) diagnosed with OAB, who qualified for intravesical BTX-A injection. Each received 100 IU of BTX-A (Botox®; Allergan), dissolved in 9.5 ml of 0.9% NaCl with the addition of 0.5 ml of MB. Cystoscopy with submucosal injection of the solution was performed systematically, including the bladder triangle. For pharmacological evaluation, quantitative determination of MB was performed on a capillary electrophoresis system with diode array detection. RESULTS In the course of 600 injections, the addition of MB facilitated the observation of the procedure; the exact distribution of the solution could not be observed in only 43 injections in seven patients. The range of distribution of the drug varied from 1 to 2.5 cm. Pharmacological evaluation based on visual observations and experiments showed that pharmaceutical interactions do not occur between MB and this commercially available formulation of BTX-A. CONCLUSIONS Applying a coloured solution of BTX-A significantly facilitates observation of the procedure and assessment of drug distribution. There are no pharmaceutical interactions between MB and BTX-A.

Abstract
Onabotulinum toxin A (OBTXA) is an effective treatment for drooling. Our objective was to determine if there are histologic changes in the submandibular glands (SMGs) after repetitive OBTXA injections. The study included blinded histologic analysis and comparison of SMGs with ≥4 OBTXA injections versus controls who never received OBTXA. The number of acinar cells were counted, and the morphology of the cells was evaluated within each histologic sample of the SMGs. Thirty-one glands were analyzed (14 control, 17 cases). No physical differences were observed between the 2 acinar cell groups. There was no significant difference in the number acinar cells per surface area in the control group as compared with the OBTXA group (1.29 ± 0.13 vs 1.17 ± 0.11 cells/μm2, respectively). To conclude, no significant histologic findings were established in this first human study on SMGs post-OBTXA treatment.

Abstract
Cancer patients who undergo surgery or radiation can develop persistent focal pain at the site of radiation or surgery. Twelve patients who had surgery or radiation for local cancer and failed at least two analgesic medications for pain control were prospectively enrolled in a research protocol. Patients were injected up to 100 units of incobotulinum toxin A (IncoA) intramuscularly or subcutaneously depending on the type and location of pain (muscle cramp or neuropathic pain). Two patients passed away, one dropped out due to a skin reaction and another patient could not return for the follow up due to his poor general condition. All remaining 8 subjects (Age 31–70, 4 female) demonstrated significant improvement of Visual Analog Scale (VAS) (3 to 9 degrees, average 3.9 degrees) and reported significant satisfaction in Patients’ Global Impression of Change scale (PGIC) (7 out of 8 reported the pain as much improved). Three of the 8 patients reported significant improvement of quality of life.

Abstract
Botulinum toxin A is available under three different protein complexes that are not interchangeable until appropriate comparative studies are undertaken. The best studied for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity and overactive bladder/idiopathic detrusor overactivity is onabotulinum toxin A. This brand is only approved for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity at a dose of 200 U and idiopathic detrusor overactivity at a dose of 100 U. In patients with detrusor overactivity as a result of spinal cord injury or multiple sclerosis, 200 U of onabotulinum toxin A should be injected in 30 different sites above the trigone. It was shown to be highly effective in curing or decreasing urinary symptoms of incontinence, increasing quality of life, increasing bladder capacity and decreasing maximal detrusor pressure. This effect was independent of the concomitant use of oral anticholinergic drugs. Adverse events were mild, mainly urinary tract infections and high postvoid residual requiring clean intermittent catheterization. In patients with overactive bladder/idiopathic detrusor overactivity, 100 U of onabotulinum toxin A should be injected in 20 sites above the trigone. It markedly decreases urinary incontinence and improves quality of life. Frequency and urgency episodes are also decreased. Adverse events are mild, mainly urinary tract infections and urinary retention. The latter occurred in just 5% of the patients. Candidates for onabotulinum toxin A treatment should be warned that the effect of the toxin is transient and that repeated injections will be required to maintain the effect in the long term. There is no evidence that repeated injections will have a decreased efficacy.
