AIM:To investigate botulinum toxin A(BTXA)efficacy on small-angle(≤25Δ)acute acquired concomitant esotropia(AACE)in early-stage patients.METHODS:The electronic medical record data of AACE patients during March 2019 and June 2023 were collected in this retrospective and hospital-based cohort study.A total of 72 small-angle AACE patients received BTXA extraocular muscle injection.Patients were grouped by onset-to-treatment time(Group A:≤6mo,Group B:>6mo).Deviation of esotropia,eye alignment and stereopsis were analyzed at the period of pre/post-injection(1wk,1,3,and 6mo).Orthophoria rate at 6mo(horizontal deviation<10Δand binocular single vision)were considered as outcome index.RESULTS:There were no significant baseline differences(P>0.05)between two groups except onset-to-treatment time(2mo vs 11mo,P<0.001).Higher orthophoria rates were in Group A at last follow-up(94.74%vs 73.53%,P=0.013).Post-BTXA deviations of two groups at 1mo showed no difference(P>0.05);while in 3 and 6mo Group A was significantly smaller than group B(all P<0.001).No statistically significant differences were observed among all post-BTXA deviations of near and distance in Group A.In Group B,deviation at 3mo(near:2Δvs 0,P<0.001;distance:4Δvs 0,P<0.001)and 6mo(near:6Δvs 0,P<0.001;distance:6Δvs 0,P<0.001)was significant increased compared to deviation at 1wk after treatment.Group A showed better stereopsis recovery in last follow-up compared to Group B(80″vs 200″,P=0.002).Both groups obtained improved stereopsis after treatment(Group A:80″vs 300″,P<0.001;Group B:200″vs 300″,P=0.037).CONCLUSION:BTXA is effective for AACE with small deviation(≤25Δ)in early stage.Delayed treatment(>6mo)may reduce BTXA efficacy.Early BTXA intervention benefits long-term eye alignment and stereopsis recovery. 展开更多

BACKGROUND Nasolabial fold(NLF)depression can affect the facial appearance of patients to some extent and increase their psychological burdens.In recent years,autologous fat grafting(AFG)combined with botulinum toxin A(BTX-A)injection(AFG+BTX-A injection)has been gradually applied in the treatment of patients with NLF depression.Although studies have been conducted on the efficacy and safety of AFG+BTX-A injection in treating NLF depression,the experimental design,observational indicators,and sample enrollment criteria vary remarkably,making it difficult to draw convincing and consistent conclusions.Thus,further relevant research is warranted.AIM To assess the esthetic improvement,efficacy,and safety of AFG+BTX-A injections in patients with NLF depression.METHODS This study included 60 patients with NLF depression who were treated in our hospital from February 2019 to April 2021.These patients were categorized into control(n=30)and observation(n=30)groups.The observation group received AFG+BTX-A injection,whereas the control group underwent AFG only.All patients were evaluated using the wrinkle severity rating scale(WSRS)and global aesthetic improvement scale.The compactness of facial contours,skin evaluation indexes,adverse reactions,and satisfaction of the two groups were evaluated 3 months postoperatively.RESULTS The WSRS scores of the observation group at 1,3,and 6 months postoperatively were lower than those of the control group(P<0.05).Three months postoperatively,facial fine lines and pores showed obvious improvement and the skin index score was higher in the observation group than in the control group(P<0.05).The compactness of facial contours was better in the observation group than in the control group(P<0.05).In addition,no remarkable differences were noted in the incidence of postoperative adverse reactions such as facial stiffness,facial asymmetry,facial bruising,and facial concavity inequality(P>0.05).CONCLUSION AFG+BTX-A injection is a highly safe,cost-effective,effective,and long-lasting treatment for NLF depression with high esthetic value,which should be promoted in the future. 展开更多

BACKGROUND Neuropathic pain(NP)is the primary symptom of various neurological condi-tions.Patients with NP often experience mood disorders,particularly depression and anxiety,that can severely affect their normal lives.Microglial cells are as-sociated with NP.Excessive inflammatory responses,especially the secretion of large amounts of pro-inflammatory cytokines,ultimately lead to neuroinflam-mation.Microglial pyroptosis is a newly discovered form of inflammatory cell death associated with immune responses and inflammation-related diseases of the central nervous system.METHODS Two models,an in vitro lipopolysaccharide(LPS)-stimulated microglial cell model and a selective nerve injury model using BTX-A and SPP1 knockdown treatments,were used.Key proteins in the pyroptosis signaling pathway,NLRP3-GSDMD,were assessed using western blotting,real-time quantitative polymerase chain reaction,and immunofluorescence.Inflammatory factors[interleukin(IL)-6,IL-1β,and tumor necrosis factor(TNF)-α]were assessed using enzyme-linked immuno-sorbent assay.We also evaluated microglial cell proliferation and apoptosis.Furthermore,we measured pain sensation by assessing the delayed hind paw withdrawal latency using thermal stimulation.RESULTS The expression levels of ACS and GSDMD-N and the mRNA expression of TNF-α,IL-6,and IL-1βwere enhanced in LPS-treated microglia.Furthermore,SPP1 expression was also induced in LPS-treated microglia.Notably,BTX-A inhibited SPP1 mRNA and protein expression in the LPS-treated microglia.Additionally,depletion of SPP1 or BTX-A inhibited cell viability and induced apoptosis in LPS-treated microglia,whereas co-treatment with BTX-A enhanced the effect of SPP1 short hairpin(sh)RNA in LPS-treated microglia.Finally,SPP1 depletion or BTX-A treatment reduced the levels of GSDMD-N,NLPRP3,and ASC and suppressed the production of inflammatory factors.CONCLUSION Notably,BTX-A therapy and SPP1 shRNA enhance microglial proliferation and apoptosis and inhibit microglial death.It improves pain perception and inhibits microglial activation in rats with selective nerve pain. 展开更多

BACKGROUND Spastic pelvic floor syndrome(SPFS)is a refractory pelvic floor disease characterized by abnormal(uncoordinated)contractions of the external anal sphincter and puborectalis muscle during defecation,resulting in rectal emptation and obstructive constipation.The clinical manifestations of SPFS are mainly characterized by difficult defecation,often accompanied by a sense of anal blockage and drooping.Manual defecation is usually needed during defecation.From physical examination,it is commonly observed that the patient's anal muscle tension is high,and it is difficult or even impossible to enter with his fingers.AIM To investigate the characteristics of anorectal pressure and botulinum toxin A injection combined with biofeedback in treating pelvic floor muscle spasm syndrome.METHODS Retrospective analysis of 50 patients diagnosed with pelvic floor spasm syndrome.All patients underwent pelvic floor surface electromyography assessment,anorectal dynamics examination,botulinum toxin type A injection 100 U intramuscular injection,and two cycles of biofeedback therapy.RESULTS After the botulinum toxin A injection combined with two cycles of biofeedback therapy,the patient's postoperative resting and systolic blood pressure were significantly lower than before surgery(P<0.05).Moreover,the electromyography index of the patients in the resting stage and post-resting stages was significantly lower than before surgery(P<0.05).CONCLUSION Botulinum toxin A injection combined with biofeedback can significantly reduce pelvic floor muscle tension in treating pelvic floor muscle spasm syndrome.Anorectal manometry is an effective method to evaluate the efficacy of treatment objectively.However,randomized controlled trials are needed. 展开更多

Background:Recently,microbotulinum,a new technique that involves injecting botulinum toxin type A(BoNTA)microdroplets into superficial cutaneous tissue,has gained popularity.The precise distribution of BoNTA in the targeted area profoundly affects outcomes.Many factors may influence the effective area of BoNTA in the dermis.This study aimed to determine the dermal distribution properties of BoNTA to guide microbotulinum injection.Methods:Ten healthy males aged 18–65 years without BoNTA treatment in the previous year were recruited to receive intradermal injections in the chest and back.Ultrasound was used to ensure the intradermal delivery of injections and measure the dermal thickness.The minor iodine starch test was performed at baseline and 3 days,7 days,21 days,1 month,and 2 months after treatment.Results:All participants received intradermal injections.The dermis was thinner on the chest(thickness,0.20±0.03 cm)than on the back(thickness,0.39±0.07 cm)(P<0.05).An injection in the thicker dermis had a significantly smaller effective area at every follow-up visit.The drug concentration did not affect the effective area except at 3 days after treatment.Injection speed did not influence the effective area at any follow-up visits.Conclusion:An injection in a thicker dermis leads to a smaller effective area for intradermal injections.When the BoNTA dose is the same,the drug concentration and injection speed do not matter. 展开更多

BACKGROUND Low back pain(LBP)is a prevalent issue that orthopedic surgeons frequently address in the outpatient setting.LBP can arise from various causes,with stiffness in the paraspinal muscles being a notable contributor.The administration of Botulinum toxin type A(BoNT-A)has been found to alleviate back pain by relaxing these stiff muscles.While BoNT-A is approved for use in numerous conditions,a limited number of randomized clinical trials(RCTs)validate its efficacy specifically for treating LBP.AIM To study the safety and the efficacy of BoNT-A in minimizing pain and improving functional outcomes in patients of chronic LBP(CLBP).METHODS In this RCT,adults aged 18-60 years with mechanical LBP persisting for at least six months were enrolled.Participants were allocated to either the Drug group,receiving 200 Ipsen Units(2 mL)of BoNT-A,or the Control group,which received a 2 mL placebo.Over a 2-month follow-up period,both groups were assessed using the Visual Analog Scale(VAS)for pain intensity and the Oswestry Disability Index(ODI)for disability at the start and conclusion of the study.A decrease in pain by 50%was deemed clinically significant.RESULTS The study followed 40 patients for two months,with 20 in each group.A clinically significant reduction in pain was observed in 36 participants.There was a statistically significant decrease in both VAS and ODI scores in the groups at the end of two months.Nonetheless,when comparing the mean score changes,only the reduction in ODI scores(15 in the placebo group vs 16.5 in the drug group,clinically insignificant)was statistically significant(P=0.012),whereas the change in mean VAS scores was not significant(P=0.45).CONCLUSION The study concludes that BoNT-A does not offer a short-term advantage over placebo in reducing pain or improving LBP scores in CLBP patients. 展开更多

Background:Benign essential blepharospasm(BEB),aberrant facial nerve degeneration and hemifacial spasm(HFS)are all examples dystonia which,though not life-threatening,can have a significant impact on patient quality of life.The need for reliable self-rating surveys to monitor functional disability is fundamental.The Blepharospasm Disability Index(BSDI)is already a widely utilised and validated selfrating score for blepharospasm whilst the functional disability score(FDS)requires further validation.The principle aim of this study is to repeat validation of the FDS against the BSDI,which has been validated by several groups since its original description but only in patients with BEB.Methods:A randomised blinded prospective cohort study was conducted at a single unit on 38 patients with BEB,aberrant facial nerve degeneration and HFS.Patients were blinded to complete the FDS followed by the BSDI or the BSDI followed by the FDS with a 30-minute interval.Results:Both the FDS and BSDI were found to be reliable with high internal consistency and test-retest reliability.Both scales were also found to be moderately correlated with the Jankovic disease severity score.Conclusions:This study is the first to use the FDS as a rating scale in patients with HFS and aberrant facial nerve degeneration.It is also the first study to formally validate the FDS as an acceptable rating scale for patients with dystonia and in particular it provides validation for its use in patients with HFS and aberrant facial nerve degeneration. 展开更多

Background:Botulinum toxin type A(BTX-A)is a neuromuscular blocking agent.BTX-A inhibits acetylcholine release,causes neuromuscular transmission impairment,and decreases muscle spasms.Objective:To explore the efficacy and safety of BTX-A injection in the treatment of spastic cerebral palsy through systematic evaluation and to provide a reference for the clinical use of BTX-A.Methods:We used“Cerebral palsy”and“BTX-A”as the subject terms and used a combination of subject terms and free words for the search.We searched 7 databases,including CNKI,Wanfang,VIP,Sinomed,PubMed,Embase,and Web of science.Based on the inclusion and exclusion criteria,we screened the articles by reading their titles,abstracts,and full texts and finally included relevant literature for systematic evaluation.Result:A total of 93 papers were systematically evaluated,revealing that BTX-A injection treatment can effectively reduce muscle tone,increase joint mobility,improve gait and motor posture,and enhance gross motor movements in patients with spastic cerebral palsy.The benefits of BTX-A treatment can be sustained for 3–6 months,with motor ability improvement lasting up to 1 year.Combining BTX-A treatment with rehabilitation or external fixation therapy can enhance its efficacy.However,the effectiveness of BTX-A treatment is influenced by several factors,such as the dosage,number of injections,and patient age.Adverse reactions to BTX-A treatment are typically mild and can be relieved within 1–2 weeks.Conclusion:BTX-A injection is relatively safe but reversible. 展开更多

BACKGROUND: Early identification of patients requiring ventilator support will be beneficial for the outcomes of botulism. The present study aimed to establish a new scoring system to predict mechanical ventilation(MV) for botulism patients.METHODS: A single-center retrospective study was conducted to identify risk factors associated with MV in botulism patients from 2007 to 2022. Univariate analysis and multivariate logistic regression analysis were used to screen out risk factors for constructing a prognostic scoring system. The area under the receiver operating characteristic(ROC) curve was calculated.RESULTS: A total of 153 patients with botulism(66 males and 87 females, with an average age of 43 years) were included. Of these, 49 patients(32.0%) required MV, including 21(13.7%) with invasive ventilation and 28(18.3%) with non-invasive ventilation. Multivariate analysis revealed that botulinum toxin type, pneumonia, incubation period, degree of hypoxia, and severity of muscle involvement were independent risk factors for MV. These risk factors were incorporated into a multivariate logistic regression analysis to establish a prognostic scoring system. Each risk factor was scored by allocating a weight based on its regression coefficient and rounded to whole numbers for practical utilization([botulinum toxin type A: 1], [pneumonia: 2], [incubation period ≤1 day: 2], [hypoxia <90%: 2], [severity of muscle involvement: grade Ⅱ, 3;gradeⅢ, 7;grade IV, 11]). The scoring system achieved an area under the ROC curve of 0.82(95% CI 0.75–0.89, P<0.001). At the optimal threshold of 9, the scoring system achieved a sensitivity of 83.7% and a specificity of 70.2%.CONCLUSION: Our study identified botulinum toxin type, pneumonia, incubation period, degree of hypoxia, and severity of muscle involvement as independent risk factors for MV in botulism patients. A score ≥9 in our scoring system is associated with a higher likelihood of requiring MV in botulism patients. This scoring system needs to be validated externally before it can be applied in clinical settings. 展开更多

AIM:To investigate the relationship between benign essential blepharospasm(BEB)symptoms and depression/anxiety/sleep disorder in a prospective manner and to determine whether treatment the BEB with botulinum toxin type A(BoNT/A)can impact psychological symptoms.METHODS:This prospective interventional case series recruited 61 adults with evidence of BEB.Patients were administered the Jankovic Rating Scale(JRS),the Blepharospasm Disability Index(BSDI),Personal Health Questionnaire Depression Scale(PHQ-8),Generalized Anxiety Disorder 7-item scale(GAD-7)and the Athens insomnia scale(AIS)to evaluate the severity of BEB symptoms,depression,anxiety and sleep disorder before and 1wk,1,3mo after the BoNTA treatment.Statistical analysis was performed to assess the relationships between changes in the survey scores.RESULTS:The mean score for JRS,BSDI,PHQ-8,and GAD-7 improved significantly(P<0.0001),respectively,compared to the initial visit at follow-up.At baseline,worse BSDI scores were correlated with worse GAD-7 and PHQ-8,but not with worse AIS.At 1mo follow-up visit,there was no correlation between change in BSDI and PHQ-8/AIS,the change in GAD-7 showed a mild association with change in BSDI.The change in BSDI was correlated with the change in both PHQ-8 and GAD-7 in the subgroup of patients without a prior diagnosis of depression or anxiety.Patient satisfaction with BoNT/A treatment reached the highest at 1mo of follow-up(83.6%,51/61).CONCLUSION:BEB may lead to psychological diseases.BoNT/A can significantly improve motor and non-motor symptoms of BEB,which emphasize the effectiveness of BoNT/A and therefore pave the way for its use in the field of psychiatry.However,further research is needed to confirm these findings and understand the underlying mechanisms. 展开更多

Dystonia characterizes a group of neurological movement disorders characterized by abnormal muscle movements,often with repetitive or sustained contraction resulting in abnormal posturing.Different types of dystonia present based on the affected body regions and play a prominent role in determining the potential efficacy of a given intervention.For most patients afflicted with these disorders,an exact cause is rarely identified,so treatment mainly focuses on symptomatic alleviation.Pharmacological agents,such as oral anticholinergic administration and botulinum toxin injection,play a major role in the initial treatment of patients.In more severe and/or refractory cases,focal areas for neurosurgical intervention are identified and targeted to improve quality of life.Deep brain stimulation(DBS)targets these anatomical locations to minimize dystonia symptoms.Surgical ablation procedures and peripheral denervation surgeries also offer potential treatment to patients who do not respond to DBS.These management options grant providers and patients the ability to weigh the benefits and risks for each individual patient profile.This review article explores these pharmacological and neurosurgical management modalities for dystonia,providing a comprehensive assessment of each of their benefits and shortcomings. 展开更多

Congenital unilateral lower lip palsy(CULLP),or congenital hypoplasia of the depressor anguli oris muscle,also known as asymmetric crying facies,is a rare condition that results in asymmetry of the lower lip during smiling,laughing,and crying.Although the etiology is unknown,weakness of the depressor labii inferioris(DLI)muscle is implicated as a contributing factor.Currently,no well-established treatment options are available.This case report describes an 18-year-old male patient diagnosed with CULLP.Physical examination revealed a symmetric face at rest,but asymmetry when smiling and opening the mouth.Following the administration of lidocaine into the affected DLI muscle,the patient’s smile and lower lip symmetry were immediately restored without any adverse effects.Subsequently,administration of botulinum toxin for neuromodulation of the DLI muscle led to a significant improvement in symmetry and oral function within 2 weeks,which was sustained at 1 month and 3 months post-treatment.No adverse effects were reported,and both patients and families expressed high satisfaction with the outcomes.This case highlights the potential use of neuromodulation as a minimally invasive and effective treatment for CULLP. 展开更多

The effect of botulinum toxin type A injection on voluntary grip control was examined in a 53-year-old female, who sustained a hemorrhagic right middle cerebral artery stroke 3 years previously, which resulted in finger flexor spasticity and residual weak finger/wrist extension. The patient received 50 units of botulinum toxin type A injection each to the motor points (2 sites/muscle) of the left flexor digitorum superficialis and flexor digitorum profundus, respectively. Botulinum toxin injection led to weakness and tone reduction in the spastic finger flexors, but improved grip release time in grip initiation/release reaction time tasks. Improved release time was accompanied by shortened extensor electromyography activity, and improved release time likely correlated with blocked co-contraction of finger flexors during voluntary finger extension. This case report demonstrated that botulinum toxin injection improved voluntary motor control of the hand in a chronic stroke patient with residual finger extension. 展开更多

No recommended guidelines currently exist for the therapeutic concentration or dose of botulinum toxin type A (BTXA) injected into the muscle to treat limb spasticity. Therefore, in this randomized controlled trial, we explored the safety and efficacy of two concentrations and two doses of BTXA in the treatment of spastic toot after stroke to optimize this treatment in these patients. Eligible patients (n = 104) were randomized into four groups. The triceps surae and tibialis posterior on the affected side were injected with BTXA at one of two doses (200 U or 400 U) and two concentrations (50 U/mL or 100 U/mL). 2he following assessments were conducted before as well as 4 days and 1, 2, 4, and 12 weeks after treatment: spasticity, assessed using the modified Ashworth scale; basic functional mobility, assessed using a timed up and go test; pace, assessed using a 10-meter timed walking test; and the ability to walk, assessed using Holden's graded scale and a visual analog scale. The reported results are based on the 89 patients that completed the study. We found significant differences for the two doses and concentrations of BTXA to improve the ability of patients to walk independently, with the high-dose/low-concentration combination providing the best effect. Onset and duration of the ameliorating effects of BTXA were 4-7 days and 12 weeks, respectively. Thus, BTXA effectively treated foot spasms after stroke at an optimal dose of 400 U and concentration of 50 U/mL. 展开更多

Botulinum toxin A (BTXA) has been used in several clinical trials to treat excessive glandular secretion; however, the precise mechanism of its action on the secretory function of salivary gland has not been fully elucidated. In this study, we aimed to investigate the effect of BTXA on secretion of submandibular gland in rabbits and to identify its mechanism of action on the secretory function of salivary gland. At 12 weeks after injection with 5 units of BTXA, we found a significant decrease in the saliva flow from submandibular glands, while the salivary amylase concentration increased. Morphological analysis revealed reduction in the size of acinar cells with intracellular accumulation of secretory granules that coalesced to form a large ovoid structure. Expression of M3-muscarinic acetylcholine receptor (M3 receptor) and aquaporin-5 (AQP5) mRNA decreased after BTXA treatment, and distribution of AQP5 in the apical membrane was reduced at 1, 2 and 4 weeks after BTXA injection. Furthermore, BTXA injection was found to induce apoptosis of acini. These results indicate that BTXA decreases the fluid secretion of submandibular glands and increases the concentration of amylase in saliva. Decreased expression of M3 receptor and AQP5, inhibition of AQP5 translocation, and cell apoptosis might involve in BTXA-reduced fluid secretion of submandibular lands. 展开更多

BACKGROUND A large proportion of patients with Hirschsprung disease experience persistent obstructive symptoms after corrective surgery.Persistent obstructive symptoms may result in faecal stasis that can develop into Hirschsprung-associated enterocolitis,a potential life-threatening condition.Important treatment to improve faecal passage is internal anal sphincter relaxation using botulinum toxin injections.AIM To give an overview of all empirical evidence on the effectiveness of botulinum toxin injections in patients with Hirschsprung disease.METHODS A systematic review and meta-analysis was done by searching PubMed,EMBASE and the Cochrane Library,using entry terms related to:(1)Hirschsprung disease;and(2)Botulinum toxin injections.14 studies representing 278 patients met eligibility criteria.Data that were extracted were proportion of patients with improvement of obstructive symptoms or less enterocolitis after injection,proportion of patients with adverse effects and data on type botulinum toxin,mean dose,average age at first injection and patients with associated syndromes.Random-effects meta-analysis was used to aggregate effects and random-effects meta-regression was used to test for possible confounding factors.RESULTS Botulinum toxin injections are effective in treating obstructive symptoms in on average 66%of patients[event rate(ER)=0.66,P=0.004,I2=49.5,n=278 patients].Type of botulinum toxin,average dose,average age at first injections and proportion of patients with associated syndromes were not predictive for this effect.Mean 7 duration of improvement after one botulinum toxin injections was 6.4 mo and patients needed on average 2.6 procedures.There was a significant higher response rate within one month after botulinum toxin injections compared to more than one month after Botulinum toxin injections(ER=0.79,vs ER=0.46,Q=19.37,P<0.001).Botulinum toxin injections were not effective in treating enterocolitis(ER 0.58,P=0.65,I2=71.0,n=52 patients).There were adverse effects in on average 17%of patients(ER=0.17,P<0.001,I2=52.1,n=187 patients),varying from temporary incontinence to mild anal pain.CONCLUSION Findings from this systematic review and meta-analysis indicate that botulinum toxin injections are effective in treating obstructive symptoms and that adverse effects were present,but mild and temporary. 展开更多

AIM: To study the effect of botulinum toxin in patients with chronic anal fissure after biliopancreatic diversion (BPD) for severe obesity. METHODS: Fifty-nine symptomatic adults with chronic anal fissure developed after BPD were enrolled in an open label study. The outcome was evaluated clinically and by comparing the pressure of the anal sphincters before and after treatment. All data were analyzed in univariate and multivariate analysis. RESULTS: Two months after treatment, 65.4% of the patients had a healing scar. Only one patient had mild incontinence to flatus that lasted 3 wk after treatment, but this disappeared spontaneously. In the multivariate analysis of the data, two registered months after the treatment, sex (P = 0.01), baseline resting anal pressure (P = 0.02) and resting anal pressure 2 mo after treatment (P < 0.0001) were significantly related to healing rate.CONCLUSION: Botulinum toxin, despite worse results than in non-obese individuals, appears the best alternative to surgery for this group of patients with a high risk of incontinence. 展开更多

Objective To evaluate efficacy and safety of botulinum toxin type B (BTX-B) in treatment of movement disorders including blepharospasm, oromandibular dystonia, hemifacial spasm, tremor, tics, and hypersecretory disorders such as sia-lorrhea and hyperhidrosis. Methods A retrospective study of BTX-B injections in treatment of 58 patients with various neurological disorders was performed. The mean follow-up time was 0.9 ± 0.8 years. Results of the first and last treatment of patients with at least 3 injection sessions were compared. Results The response of 58 patients to a total of 157 BTX-B treatment sessions was analyzed. Of the 157 treatment sessions, 120 sessions (76.4%) resulted in moderate or marked improvement while 17 sessions (10.8%) had no response. The clinical benefits after BTX-B treatment lasted an average of 14 weeks. Of the 41 patients with at least 3 injection ses-sions (mean 10 ± 8.6), most patients needed increased dosage upon the last session compared to the first session. Nineteen patients (32.8%) with 27 sessions (17.2%) reported adverse effects with BTX-B treatment. Conclusions Though most patients require increased dosage to maintain effective response after repeated injections, BTX-B is an effective and safe treatment drug for a variety of movement disorders, as well as drooling and hyperhidrosis. 展开更多

AIM: To investigate the effects of micro-injection of botulinum toxin A(BTXA) on acute acquired comitant esotropia(AACE). METHODS: A total of 33 AACE patients who underwent BTXA micro-injection at Renmin Hospital of Wuhan University from September 1^(st), 2019 to July 1^(st), 2021 were retrospective analyzed. Esotropia, eye alignment, stereopsis, and complications were examined at baseline(except complications), 1wk, 1, 3, and 6mo after injection. RESULTS: The average angle of deviation before injection was(+20.24±6.80)^(Δ) at near and(+24.76±6.43)^(Δ) at distance, while(+5.15±5.85)^(Δ) at near and(+7.30±6.17)^(Δ) at distance 6mo after treatment(P<0.05). Six months after injection, the stereopsis of patients had improved. The number of patients having no stereopsis(>800 seconds of arc) decreased from 11 to 3. The number of patients having peripheral stereopsis(300-800 seconds of arc), macular stereopsis(70-200 seconds of arc) and central concave stereopsis(≤60 seconds of arc) increased from 10 to 11, 10 to 12, and 2 to 7, respectively. At the follow-ups at 1wk, 1, 3, and 6mo after injection, success rates were 96.97%, 96.97%, 93.94% and 87.88%, respectively. One week after injection, two patients(6.07%) showed subconjunctival hemorrhage;three patients(9.09%) showed limited eye movement and one patient(3.03%) showed mild vertical strabismus. All the symptoms disappeared by the final follow-up.CONCLUSION: Micro-injection of BTXA can reduce diplopia and improve binocular vision function of AACE patients. Furthermore, the operation is relatively safe with few complications, making it an ideal treatment modality for AACE. 展开更多
