RESUMO
Objective Exploring the efficacy and safety of botulinum toxin type A(BTX-A)combined with pulsed radiofrequency(PRF)in the treatment of postherpetic neuralgia(PHN).Methods A total of 80 patients with PHN were collected.They were randomly divided into experimental group(Group B)and control group(Group C),Group B was treated with BTX-A intradermal injection combined with PRF,and Group C was treated with lidocaine intradermal injection combined with PRF.Numeric pain score(NRS),Simplified McGill Pain Questionnaire(SF-MPQ)and Sleep Quality Score(QS)were used to assess the patients'pain level and sleep quality preoperatively,1,3,and 7 days postoperatively,and 1,2,and 3 months postoperatively.The patients'postoperative adverse reac-tions were collected.Interleukin-1β(IL-1β)and calcitonin gene-related peptide(CGRP)levels in patients'serum were measured preoperatively and 3 days postoperatively.Results The NRS scores,SF-MPQ scores,and QS scores of group B and group C were significantly lower at all postoperative time points compared to preoperative ones(P<0.05).The NRS and SF-MPQ score were significantly lower in group B at 1,2,and 3 months postoperatively compared with group C(P<0.05);and group B had significantly lower QS scores at 2 and 3 months postoperatively(P<0.05).The effective rate of pain relief at 3 months postoperatively in group B(90%)was statistically signifi-cant(P<0.05)compared with group C(56.7%).No serious adverse reactions occurred in either group.The levels of IL-1β and CGRP in serum of patients in both groups were significantly decreased at 3 days after surgery compared with the preoperative period,and the degree of decrease of IL-1β and CGRP in group B was more significant than that in group C(P<0.05).Conclusion BTX-A combined with PRF treatment for PHN can effectively reduce its pain level,improve the quality of sleep,and is safe.
RESUMO
@#Myogenous temporomandibular disorder (M-TMD) is one of the main subtypes of temporomandibular disorder (TMD) and typically manifests as masticatory myofascial pain; the incidence of TMD has been increasing annually in recent years. Botulinum toxin type A (BTX-A) is a potent neurotoxin produced by Clostridium botulinum. BTX-A inhibits the release of acetylcholine from the presynaptic membrane, thereby blocking neuromuscular junction signaling. The noncosmetic application of BTX-A in the oral and maxillofacial regions is a prominent research topic. In recent years, an increasing number of studies have focused on the application of BTX-A in the treatment of M-TMD. The results of a literature review revealed that an appropriate dose (10-50 U unilaterally) of BTX-A administered in a single injection into the masticatory muscles can effectively treat myalgia over a period of 3-6 months. Common adverse effects, such as masticatory weakness and facial paralysis, are transient and can be avoided by standardized injection techniques. However, there is a lack of standardized guidelines for injection techniques in clinical practice.
RESUMO
Objective: The efficacy of botulinum toxin type A (BoNT-A) injection on spasticity has usually been measured using the range of motion (ROM) of joints and Modified Ashworth Scale (MAS); however, they only evaluate muscle tone at rest. We objectively analyzed the gait of three patients with hemiplegia using three-dimensional motion analysis and ground reaction force (GRF) systems to evaluate muscle tone during gait.Materials and Methods: We measured passive ankle dorsiflexion ROM with knee extension and the MAS score for clinical evaluation, and gait speed, stride length, single-leg support phase during the gait cycle, joint angle, joint moment, and GRFs for kinematic evaluation before and one month after BoNT-A injection.Results: All patients showed an increase in ankle dorsiflexion ROM, improvement in MAS score, and increase in stride length. Case 1 showed an increase in gait speed, prolongation of the single-leg support phase, increase in hip extension angle and moment, and improvement in the vertical and anterior-posterior components of the GRFs. Case 2 showed an increase in gait speed, improvement in double knee action, increase in ankle plantar flexion moment, and improvement in propulsion in the progressive component of the GRFs. Case 3 exhibited a laterally directed force in the GRFs.Conclusion: We evaluated the effects of BoNT-A injections in three patients with hemiplegia using three-dimensional motion analysis and GRFs. The results of the gait analysis clarified the improvements and problems in hemiplegic gait and enabled objective explanations for patients.

RESUMO
@#Objective To compare and analyze the efficacy and safety of 5-needle injection and standard 20-needle injection in the treatment of overactive bladder with botulinum toxin type A.Methods A retrospective analysis was performed on 48 patients with overactive bladder who received intravesical injection of botulinum toxin type A in the Department of Urology,Hangzhou Third People's Hospital from January 2015 to December 2022,and they were divided into two groups according to the number of injections,with 24 patients in each group.The observation group received 5-needle injection,and the control group received standard 20-needle injection.Average daily frequency of urination,international consultation on incontinence questionnaire-overactive bladder,international consultation on incontinence questionnaire-overactive bladder(ICIQ-OAB)score,overactive bladder(OAB-Q)score,visual analogue scale(VAS),patient generated index(PGI-I)score,complication rate and willingness to repeat injection were recorded before and after treatment in two groups,respectively.Results There were no significant differences in age,gender,course of disease,average daily frequency of urination before treatment and baseline data of each score between the two groups,which were comparable.All patients completed treatment,and compared with before treatment,the mean daily frequency of urination,ICIQ-OAB and OAB-Q were improved after treatment(P<0.05),there was no significant difference between the two groups(P>0.05).There were no significant differences in scores and incidence of complications between the two groups after treatment(P>0.05).However,patients in the observation group were more willing to receive another injection(P<0.05).Conclusion The efficacy and safety of 5-needle vesical injection of botulinum toxin type A in the treatment of overactive bladder is similar to that of standard 20-needle injection,which is more easily accepted by patients,and is a safe and effective alternative to standard technique.
RESUMO
Thyroid-associated ophthalmopathy(TAO)is an autoimmune inflammatory disease involving multiple orbital tissues with a variety of clinical manifestations, which has serious effects on the life quality of patients.Interventions of TAO mainly include medical treatment to stabilize thyroid function, reduce inflammation and regulate immune function, as well as surgical treatment to relieve ocular symptoms. Botulinum toxin type A can paralyze muscles by blocking nerve impulse conduction at the neuromuscular junction, which is of certain therapeutic value for restrictive strabismus due to extraocular muscle involvement and upper eyelid retraction due to involvements of levator palpebrae superioris and Müller's muscle in TAO patients, especially when they have surgical contraindications, lack surgical opportunity, or refuse surgery. This paper reviews the application of botulinum toxin type A in the treatment of TAO, focusing on its pharmacological mechanism, dosage, effectiveness, and possible complications when treating restrictive strabismus and upper eyelid retraction, and discussing potential therapeutic values of botulinum toxin type A for intraocular pressure elevation, glabellar frown lines and dry eye caused by extraocular muscle compression in TAO patients, in order to provide a reference for clinical intervention.
RESUMO
@#Botulinum toxin poisoning is a neuroparalytic disorder caused by botulinum toxin,mostly involving the presynaptic membrane of cranial nerves and peripheral neuromuscular junctions,manifesting as flaccid,symmetrical,descending paralysis. Due to the diverse clinical manifestations,it is easily confused with myasthenia gravis and Guillain-Barré syndrome in the absence of a clear history of suspected food consumption. We report a case of botulinum toxin poisoning characterized by fluctuating myasthenia gravis,bilateral ptosis,dysphagia,and double vision in our hospital. The patient denied a history of food or drug poisoning,had a positive fatigue test and a positive neostigmine test,and was initially diagnosed with myasthenia gravis. After treatment with pyridostigmine bromide,hormones,and immunosuppressants,there was no significant relief of symptoms. After detailed questioning,the patient recalled that his family members and friends had mild malaise and dizziness,which were initially overlooked. They had consumed the same homemade raw sauce from a jar at different times prior to the onset of the illness. Serological tests confirmed the diagnosis of botulinum toxin type A poisoning in the patient,as well as his family members and friends. Early diagnosis is key to the management of botulism poisoning. Patients presenting with fluctuating myasthenia,bilateral ptosis,dysphagia,and double vision should be questioned in detail about their history of consuming suspected food to rule out botulinum toxin poisoning,thereby avoiding misdiagnosis and delayed treatment.
RESUMO
Objective:To observe any therapeutic effect of combining botulinum toxin type A (BTX-A) with rehabilitation training in treating Parkinson′s disease (PD) patients with striatal foot deformity (SFD).Methods:A total of 68 PD patients with SFD were randomly divided into a control group and a treatment group. Both groups were given routine medication with pramipexole and dopamine receptor agonists and received lower limb rehabilitation training, including passive activity training, strength training and walking training. The treatment group was additionally injected with BTX-A. Sciatic pain was quantified using a visual analogue scale. The Unified Parkinson′s Disease Rating Scale-lower limb motor lower limb motor function (UPDRS-LLM) scale, the Berg balance scale and the modified Barthel index were applied to test all of the participants before the experiment and on the 7th, 14th and 30th day of the treatment.Results:The average scores of the control group on all of measures at were significantly better than those of the control group at the same time points, and by the 14th and 30th day had improved significantly compared with those before treatment.Conclusion:Supplementing rehabilitation training with BTX-A can significantly improve foot deformity and relieve the muscle tension and spastic pain of PD patients with SFD, promoting the motor functioning of their lower limbs, their balance and their performance in the activities of daily living.

RESUMO
A síndrome de arlequim é uma rara desordem autonômica que se caracteriza por anidrose e falta de rubor unilateral da face, podendo acometer as regiões cervical e torácica. De forma paradoxal, há rubor e sudorese compensatórios no lado contralateral à alteração. É idiopática na maioria dos casos, mas pode ser congênita, secundária a lesões estruturais e à iatrogenia pós-cirúrgica. O tratamento é direcionado ao fator causal. Descreve-se caso de paciente com diagnóstico de síndrome de arlequim idiopática, sendo realizada aplicação de toxina botulínica na hemiface acometida pelos sintomas compensatórios com boa resposta terapêutica
Harlequin syndrome is a rare autonomic disorder characterized by anhidrosis and lack of unilateral flushing of the face, which may affect the cervical and thoracic regions. Paradoxically, there is compensatory flushing and sweating on the contralateral side to the alteration. It is idiopathic in most cases, but it can be congenital or secondary to structural or post-surgical iatrogenic lesions. Treatment is directed at the causative factor. We describe the case of a patient with a diagnosis of idiopathic Harlequin Syndrome with botulinum toxin application in the hemiface affected by compensatory symptoms with good therapeutic response.

RESUMO
RESUMEN: Introducción: El bruxismo del sueño es un comportamiento que se caracteriza por la actividad repetitiva de los músculos masticadores. Varias terapias para el manejo del bruxismo del sueño se centran en la relajación de los músculos involucrados, incluyendo la inyección intramuscular de Toxina Botulínica tipo A (BoNTA). A pesar de que se ha comprobado la efectividad de esta terapia frente al dolor subjetivo, cuando se asocia a bruxismo del sueño, es necesario determinarla frente a desenlaces objetivos, tanto a nivel craneofacial como sistémico. Además, se debe evaluar también la seguridad de esta intervención frente a eventos adversos tales como afecciones estéticas, debilidad masticatoria y pérdida ósea mandibular, entre otros. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un meta-análisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos 11 revisiones sistemáticas que en conjunto incluyeron 9 estudios primarios, de los cuales, 8 corresponden a ensayos aleatorizados. Concluimos que la inyección intramuscular de toxina botulínica tipo A podría disminuir el dolor en reposo, presentar poca o nula diferencia en dolor durante la masticación y mejorar la autoevaluación del bruxismo, pero la certeza de la evidencia es baja. Por otra parte, no es posible establecer con claridad si el uso de Toxina Botulínica Tipo A disminuye el número de eventos de bruxismo, ya que la certeza de la evidencia ha sido evaluada como muy baja. Finalmente y a pesar de la evidencia existente respecto de los potenciales eventos adversos producto de la intervención con Toxina Botulínica Tipo A en los músculos masticatorios, los ensayos clínicos fallan en evaluarlos y reportarlos.
ABSTRACT: Introduction: The sleep bruxism is a behavior that impacts the craniofacial musculoskeletal system characterized by repetitive activity of the masticatory muscles. Several management strategies for sleep bruxism are focused of the relaxation of the involved masticatory muscles, including the intramuscular injection of botulinum toxin type A (BoNTA). Although the effectiveness of BoNTA for myofascial pain, when related with the sleep bruxism in adult patients, it is necessary to determine its effectiveness using objective outcomes at both craniofacial and systemic levels. In addition, it is necessary to determine the safety of this intervention in the context of adverse events such as aesthetic alterations, reduced masticatory function, mandibular bone loss among others. Methods: A search was performed using Epistemonikos, the biggest database for systematic reviews in health, with is maintained by screening of multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. Data from systematic reviews were extracted, and analysis of the primary studies was performed, including a meta-analysis and a summary of findings table using GRADE assessment. Results and conclusions: 11 systematic reviews were identified, and 9 primary studies were included. 8 out of these 9 studies corresponded to randomized clinical trials. We conclude that the intramuscular injection of BoNTA may reduce the pain during rest and results in either little or none difference in pain during mastication, when pain is associated with sleep bruxism in adult patients. Also, low evidence is determined for auto-report and subjective evaluation of sleep bruxism among adult patients. Additionally, it is not possible to determine if the BoNTA intervention is effective to reduce the bruxism events due to the low evidence. Finally, although evidence regarding adverse events such as mandibular bone loss after BoNTA intervention in masticatory muscles has been published at preclinical and clinical levels, the clinical trials fail to consider and to report these outcomes.

RESUMO
Objective:To observe the effect of a wrist brace on activities of spastic hemiplegic hand after stroke, based on Botulinum toxin type A (BTX-A) injection and electrical stimulation. Methods:From January, 2016 to December, 2018, 52 stroke patients with spastic hemiplegia on upper extremities accepted BTX-A injection, and electrical stimulation two days later, while group A (n = 26) wore a wrist brace during stimulation and group B (n = 26) did not. They were assessed with modified Ashworth Scale (MAS), Box and Block test (BBt) and Action Research Arm Test (ARAT) before treatment (T0), and two (T1), four (T2) and twelve 12 (T3) weeks after treatment. Results:The scores of MAS, BBt and ARAT improved after treatment in both groups (Ftime > 118.32,P < 0.001), and improved more in group A than in group B in the scores of BBt and ARAT at each time point (Fgroup > 31.26,P < 0.001;Finteract = 10.65,P < 0.001). Conclusion:Based on the BTX-A injection and electrical stimulation, wearing a wrist brace would further improve the activities of hand for stroke patients.
RESUMO
Objective To summarize the adverse reactions of blepharospasm (BSP) and hemifacial spasm (HFS) after botulinum toxin A (BoNT-A) injection and offer corresponding responses.Methods Clinical data of 163 BSP patients and 221 HFS patients,admitted to and subjected to BoNT-A injection in our hospital from September 2017 to October 2019,were analyzed retrospectively.Albert and Cohen evaluation scale was used to evaluate the therapeutic efficacy after injection.All adverse reactions were recorded and corresponding responses were proposed.Results The effective rates of BoNT-A injection for BSP and HFS were 97.5％ and 100％,respectively.The most common early-onset adverse reactions were local pain (BSP:13.5％;HFS:17.2％) and hematoma (BSP:3.7％;HFS:4.5％);the late-onset adverse reactions included dry eyes/epiphora (BSP:9.8％;HFS:11.3％),incomplete closure of eyelid (BSP:20.2％;HFS:20.4％),facial stiffness (HFS:39.4％) and asymmetry (HFS:11.8％),and eyelid edema could be noted in a few patients (BSP:1.2％;HFS:1.4％).The main measures on reducing or avoiding adverse reactions after injection included appropriate injection apparatus,accurate injection sites,exact drug doses,and consideration of the individual differences of patients.Conclusion BoNT-A is effective in the treatment of BSP and HFS,but it is necessary to avoid early-onset and late-onset adverse reactions to maximize the benefits of patients.
RESUMO
A toxina botulínica tem como mecanismo de ação a paralisia neuromuscular flácida transitória. Estudos recentes estão identificando novas formas de uso da toxina botulínica para diversos fins, tanto no campo estético quanto no terapêutico. Este trabalho teve como objetivo realizar uma revisão bibliográfica sobre essas aplicações. No âmbito estético, a toxina botulínica demonstrou benefício em tratamento de cicatrizes hipertróficas, rejuvenescimento da região escrotal, definição do músculo gastrocnêmio e sendo usada em microdoses. Já no tratamento de patologias, a revisão demonstrou que a toxina botulínica pode ser útil para tratamento da neuralgia pós-herpética e de outras síndromes álgicas, da hiperidrose craniofacial, da rosácea e da doença de Hailey-Hailey.
Botulinum toxin has transient flaccid neuromuscular paralysis as its mechanism of action. Recent studies are identifying new ways to use botulinum toxin for a variety of purposes, both in the aesthetic and in the therapeutic field. This work aimed to conduct a literature review on these applications. In the aesthetic field, botulinum toxin has shown benefit in the treatment of hypertrophic scars, rejuvenation of the scrotal region, definition of the gastrocnemius muscle, and microdoses use. In the treatment of pathologies, the review has shown that botulinum toxin may be useful for the treatment of post-herpetic neuralgia and other pain syndromes, craniofacial hyperhidrosis, rosacea, and Hailey-Hailey disease.
