RESUMO

PURPOSE: Botulinum toxin type A (BTA) is an adjuvant tool used in the preoperative optimization of complex hernias before abdominal wall reconstruction (AWR). This study aims to investigate changes in the abdominal cavity and hernia sac dimensions after BTA application. METHOD: A prospective study with 27 patients with a hernia defect of ≥ 10 cm and loss of domain (LOD) ≥ 20% underwent AWR. Computed tomography (CT) measurements and volumetry before and after the application of BTA were performed. Intraoperative and postoperative outcomes were evaluated. RESULTS: Imaging post-BTA revealed hernia width reduction of 1.9 cm (p = 0.002), lateral abdominal wall muscle elongation of 3.1 cm (p < 0.001), hernia volume reduction (HV) from 2.9 ± 0.9L to 2.4 ± 0.8L (p < 0.001), increase in abdominal cavity volume (ACV) from 9.7 ± 2.5L to 10.3L ± 2.4L (p = 0.003), and a reduction in the HV/ACV ratio from 30.2 ± 5% to 23.4 ± 6% (p < 0.001). Fascial closure was achieved in 92.6% of cases and component separation was required in 78%. The average variation in pulmonary plateau pressure was 3.53 cmH2O, and there were no postoperative respiratory failure recorded. At the 90-day follow-up, the wound morbidity rate was 25%, unplanned readmissions were 11%, and hernia recurrence 7.4%. CONCLUSION: BTA produces measurable volumetric changes in abdominal wall and appears to facilitate fascial closure. Further studies are required to determine the role of BTA in the surgical armamentarium for complex hernia repair.

RESUMO

OBJECTIVE: To compare efficacy and side effect profile data on conservative, behavioral, pharmacological, and surgical treatments used for pediatric saliva control. STUDY DESIGN: A cohort study of children (n = 483) referred to a specialty Saliva Control service between May 2014 and November 2019 was performed, using quantitative data from pretreatment and post-treatment questionnaires (the Drooling Impact Scale [DIS], Drooling Rating Scale [DRS]) and recording of side effects. Overall, 483 children were included; treatment choices were based on published international guidelines. RESULTS: The greatest improvement was seen after intraglandular botulinum toxin A (BTX-A) injections (n = 207; 551 courses; mean DIS change, 34.7; 95% CI = 29.2-35.7) or duct transpositional surgery (n = 31; mean change in DIS, 29.0; 95% CI, 22.3-35.7). Oral anticholinergics were associated with good outcomes, with no significant statistical difference between glycopyrronium bromide (n = 150; mean DIS change, 21.5; 95% CI, 19.1-24.0) or trihexyphenidyl (n = 87; mean DIS change, 22.4; 95% CI, 18.9-25.8). Inhaled ipratropium bromide was not as efficacious (n = 80; mean DIS change, 11.1; 95% CI, 8.9-13.3). Oromotor programs were used in a selected group with reliable outcomes (n = 9; mean DIS change, 13.0). Side effects were consistent with previous studies. Overall, in cases of milder severity, enterally administered therapies provided a good first-line option. With more severe problems, BTX-A injections or saliva duct transpositional surgery were more effective and well tolerated. CONCLUSIONS: We describe a large, single-center pediatric saliva control cohort, providing direct comparison of the efficacy and side effect profiles for all available interventions and inform clinical practice for specialists when considering different options. BTX-A injections or saliva duct transpositional surgery seem to be more effective for saliva control that is more severe.

RESUMO

Objective: Dyssynergic defaecation (DD) is an important cause of chronic constipation. In patients where conservative treatments fail, injections of botulinum toxin A (BTX-A) into the puborectalis and anal sphincter muscles can be effective. Complications of this procedure are reported to be rare and generally mild. This study aimed to identify the complication rates and short- to medium-term success rates of BTX-A injections as a treatment for DD. Methods: A retrospective review was conducted on patients diagnosed with DD who had undergone BTX-A injections at a functional colorectal unit. Patient demographics, manometric assessment, conservative management, and injection technique were collected through a chart review. Subjective patient reports and comparison of pre- and postprocedure symptom scores were used to determine efficacy. Results: The 21 patients included (24 procedures, with 3 patients receiving BTX-A on two separate occasions) all received stool modification and dietary advice, and 20 patients underwent pelvic floor physiotherapy, averaging 8 sessions. The injections were universally applied under general anesthetic, primarily targeting the anal sphincter and/or puborectalis muscles. There were 6 reports of faecal urge/incontinence, with all but one being resolved within weeks. The BTX-A injection was subjectively reported as beneficial in 19 cases, averaging 4.7 months (range 1-32) of improvement. Only 2 were sustained beyond 12 months. Despite overall improvements in symptom scores from pre- to postprocedure, none were statistically significant. Conclusion: Following a course of conservative management, the BTX-A injection appears to be a safe treatment for DD, but only has short term efficacy. (AU)

RESUMO

Post-incisional ventral hernia is estimated at 5-30%, when the content of the abdominal cavity migrates to the hernial sac (HSV), with a HSV/abdominal cavity volume ratio > 25%, conditioning systemic changes defined as "loss of domain". A 27-year-old male presented with ventral hernia with loss of domain that required pre-operative preparation techniques, using application of botulinum toxin A (IncobotulinumtoxinA) and pneumoperitoneum, both guided by image. A ventral plasty was performed with adequate return of the viscera to the abdominal cavity. The combination of both techniques seems to be a safe procedure to carry out a tension-free repair.

La hernia ventral postincisional se estima en 5 al 30%, cuando el contenido de la cavidad abdominal migra al saco herniario, con una relación VSH/VCA > 25% condicionando cambios sistémicos se define como "pérdida de dominio". Masculino de 27 años con hernia ventral con pérdida de dominio que ameritó técnicas de preparación preoperatoria, utilizando toxina botulínica A (IncobotulinumtoxinA) y neumoperitoneo, ambos guíados por imagen. Se realizó una plastia ventral con adecuado regreso de las vísceras a la cavidad abdominal. La combinación de ambas técnicas es un procedimiento seguro para realizar una reparación libre de tensión.

RESUMO

Introduction: Aesthetic applications of botulinum toxin type A (BoNT-A) may lead to some complications, including unwanted muscle paralysis. Moreover, BoNT-A effects may last several months, and there is no medical intervention so far to accelerate muscle function recovery. Case Report: A female patient with a movement disorder of the mimic muscles resulting from BoNT-A injections received daily sessions of photobiomodulation therapy (PBMT). A fast improvement in both facial asymmetry and muscle function was noted within a few weeks. After nine weeks, almost complete recovery was achieved. Conclusion: According to the current case, PMBT seems to be an effective intervention to accelerate muscle function recovery following BoNT-A use.

RESUMO

Unilateral peripheral facial nerve palsy jeopardizes quality of life, rendering psychological consequences such as low self-esteem, social isolation, anxiety, and depression. Among therapeutical approaches, use of Botulinum toxin type A (BoNT-A) on the nonparalyzed side has shown promising results and improvement of quality of life. Nevertheless, the correct technique is paramount, since over-injection of the muscles can result in lack of function, leading to a "paralyzed" appearance, and even worse, functional incompetence, which may cause greater distress to patients. Therefore, the objective of this article is to provide a practical guideline for botulinum toxin use in facial palsy. To this aim, adequate patient assessment, BoNT-A choice, injection plan and dosage, and injection techniques are covered.

RESUMO

BACKGROUND: Hereditary spastic paraplegia presents spasticity as the main clinical manifestation, reducing gait quality and producing incapacity. Management with botulinum toxin type A (BoNT-A) is not well elucidated. The objective of the current study was to evaluate the efficacy and safety of BoNT-A in patients with hereditary spastic paraplegias. METHODS: This was a double-blind, randomized, placebo-controlled crossover trial. Each participant was randomly assigned to receive 1 injection session of either BoNT-A (100 IU/2 mL of Prosigne in each adductor magnus and each triceps surae) or saline 0.9% (2 mL). The primary outcome measure was change from baseline in maximal gait velocity, and secondary outcome measures included changes in gait at self-selected velocity, spasticity, muscle strength, Spastic Paraplegia Rating Scale, pain, fatigue, and subjective perception of improvement. We also looked at adverse events reported by the patients. RESULTS: We enrolled 55 patients, 36 of whom were men and 41 with the pure phenotype. Mean age was 43 ± 13.4 years (range, 19-72 years), mean age of onset waws 27 ± 13.1 years (range, <1 to 55 yars), and mean disease duration was 17 ± 12.7 years (range, 1-62 years). Compared with baseline, we did not find significant differences between groups in primary and secondary outcomes, except for reduction in adductor tone (P = 0.01). The adverse events were transient and tolerable, and their incidence did not significantly differ between treatments (P = 0.17). CONCLUSIONS: BoNT-A was safe in patients with hereditary spastic paraplegias and reduced the adductor tone, but it was not able to produce functional improvement considering the doses, injection protocol, measures, and instruments used. © 2021 International Parkinson and Movement Disorder Society.

RESUMO

Botulinum toxin-A (BoNT-A) is an effective treatment for cervical dystonia (CD) and spastic paresis (SP), but it requires in-depth knowledge of anatomy and injection techniques. The Ixcellence Network® is an educational programme to provide neurology, neuropaediatrics, and physical medicine and rehabilitation (PMR) specialists with access to best clinical practices and innovations regarding SP and CD management with BoNT-A. To assess the benefits of such educational programmes and identify unmet needs, a multidisciplinary scientific committee designed INPUT (INjection Practice, Usage & Training), an international multicentric survey describing training and practices among this trained and experienced population. A self-completed questionnaire was sent online to 553 trainees and 14 trainers from the Ixcellence Network®. Among the 131 respondents, 92% specialized in PMR (48%) or neurology (44%), with a mean experience of 15.5 years in their clinical fields and 10.9 years of BoNT-A injection. Most of them (98%) reported having received training before performing their first BoNT-A injection and attending specific courses on how to perform it without any instrumental guidance (76%), and with ultrasound (73%), electrical stimulation (44%) or electromyography (41%). In terms of practices, 92% of respondents reported using at least one guidance technique while injecting, with ultrasound being the most used technique (48%). Attending specific courses was significantly associated with greater self-confidence and use, e.g. for injection with ultrasound, mean self-confidence, on a scale from 1 (not confident) to 10 (fully confident), was 7.9 for trained respondents (vs 4.0 for untrained respondents, p < 0.001) of whom 70% stated that they used this technique regularly or systematically (vs. 11% of untrained healthcare professionals (HCPs), p < 0.0001). Moreover, 84% of respondents reported having trained colleagues, residents or fellows through theoretical (70%) or practical teaching in individuals (80%) or in small groups (65%). Overall, 86% of respondents reported a notable increase over the past 5 years of the number of patients treated with BoNT-A. INPUT is the first international survey describing training and practices in SP and CD management of physicians who attended a dedicated educational programme. The results highlighted the importance of training for self-confidence, and the use of specific techniques and new approaches.

RESUMO

To accurately localize the centers of intramuscular nerve dense regions (CINDRs) of rotator cuff muscles. Twenty adult cadavers were used. The curves on skin connecting the superior angle of scapula with the acromion, and with the inferior angle of scapula were designed as the horizontal (H) and longitudinal (L) reference lines, respectively. One side of the rotator cuff muscles were removed and subjected to Sihler's staining to show intramuscular nerve dense regions, and the contralateral muscles' CINDRs were labeled with barium sulfate and scanned by computed tomography (to determine body surface projection points (P)). The intersection of the longitudinal line from point P to line H, and that of the horizontal line from point P to line L, were recorded as PH and PL, respectively. The projection of CINDRs on the anterior body surface across the saggital plane was defined as P' and the line connecting P to P' was recorded as Line PP'. Percentage positions of CINDRs of PH and PL on lines H and L, and the depths on line PP' were determined under the Syngo system. Two, four, one, and one CINDRs were identified in supraspinatus, infraspinatus, teres minor, and subscapularis muscles, respectively. The positions of PH of these CINDRs on the H-line are as follows: supraspinatus, 25.43 % and 26.59 %; infraspinatus, 53.85 %, 34.63 %, 35.96 % and 58.17 %; teres minor, 74.50 %; and subscapularis, 20.33 %. The PL on the L-line: supraspinatus, 11.09 % and 14.83 %; infraspinatus, 21.59 %, 27.93 %, 48.55 % and 57.52 %; teres minor, 68.28 %; and subscapularis, 52.82 %. The depth on line PP': supraspinatus, 24.83 % and 25.40 %; infraspinatus, 21.55 %, 16.10 %, 10.01 % and 8.14 %; teres minor, 13.27 %; and subscapularis, 22.88 %. The identification of these CINDRs should provide the optimal target position for injecting botulinum toxin A to treat rotator cuff muscles spasticity accompanied by shoulder pain and to improve the efficiency and efficacy of blocking target localization.

Con el objetivo de localizar con precisión los centros de las regiones densas del nervio intramuscular (CRDNI) de los músculos del manguito rotador, se utilizaron veinte cadáveres adultos. Las curvas en la piel que conectan el ángulo superior de la escápula con el acromion y con el ángulo inferior de la escápula se determinaron como líneas de referencia horizontales (H) y longitudinales (L), respectivamente. Se extrajo de un lado los músculos del manguito rotador y se sometió a la tinción de Sihler para mostrar regiones densas de nervios intramusculares, y los CRDNI de los músculos contralaterales se marcaron con sulfato de bario y se escanearon mediante tomografía computarizada (para determinar los puntos de proyección de la superficie corporal (P)). La intersección de la línea longitudinal desde el punto P a la línea H, y de la línea horizontal desde el punto P a la línea L, se registraron como PH y PL, respectivamente. La proyección de CRDNI en la superficie del cuerpo anterior a través del plano sagital se definió como P 'y la línea que conecta P a P' se registró como Línea PP '. Las posiciones porcentuales de los CRDNI de PH y PL en las líneas H y L, y las profundidades en la línea PP 'se determinaron bajo el sistema Syngo. Se identificaron dos, cuatro, uno y un CINDR en los músculos supraespinoso, infraespinoso, redondo menor y subescapular, respectivamente. Las posiciones de PH de estos CRDNI en la línea H son las siguientes: supraespinoso, 25,43 % y 26.59 %; infraspinatus, 53,85 %, 34,63 %, 35,96 % y 58,17 %; redondo menor, 74,50 %; y subescapular, 20,33 %. El PL en la línea L: supraespinoso, 11.09 % y 14.83 %; infraspinatus, 21,59 %, 27,93 %, 48,55 % y 57,52 %; redondo menor, 68.28 %; y subescapular, 52,82 %. La profundidad en la línea PP ': supraespinoso, 24,83 % y 25,40 %; infraspinatus, 21,55 %, 16,10 %, 10,01 % y 8,14 %; redondo menor, 13.27 %; y subescapularis, 22,88 %. La identificación de estos CRDNI debería proporcionar la posición objetivo óptima para inyectar la toxina botulínica A para tratar la espasticidad de los músculos del manguito rotador acompañada de dolor en el hombro y para mejorar la eficiencia y la eficacia del bloqueo de la localización del objetivo.

RESUMO

INTRODUCTION AND AIMS: Pyloric sphincter abnormalities may be detected in gastroparesis. Botulinum toxin A (BoNT/A) injection into the pylorus has been used to treat gastroparesis with varying results. The aim of the present article was to assess whether pyloric sphincter characteristics using the endoscopic functional lumen imaging probe (EndoFLIP®) with impedance planimetry in patients with gastroparesis correlated with symptoms, gastric emptying, and therapeutic response to pyloric sphincter BoNT/A injection. METHODS: EndoFLIP® study was performed on patients undergoing gastroparesis treatment with BoNT/A. The gastroparesis cardinal symptom index (GCSI) was applied prior to treatment and at post-treatment weeks 2, 4, 8, and 12. RESULTS: Forty-four patients were enrolled (30 with idiopathic gastroparesis, 14 with diabetic gastroparesis). Smaller pyloric diameter, cross-sectional area (CSA), and distensibility correlated with worse vomiting and retching severity at baseline. Greater gastric retention tended to correlate with decreased CSA and pyloric distensibility. BoNT/A treatment resulted in a significant decrease in the GCSI score at 2 and 4 weeks after treatment, but not at post-treatment weeks 8 or 12. Nausea, early satiety, postprandial fullness, and upper abdominal pain improved up to 12 weeks, whereas loss of appetite, stomach fullness, and stomach visibly larger improved only up to 4 weeks. Retching and vomiting failed to improve. Greater pyloric compliance at baseline correlated with greater improvement in early satiety and náusea at 8 weeks and greater pyloric distensibility correlated with improvement in upper abdominal pain. CONCLUSIONS: EndoFLIP® characteristics of the pylorus provided important pathophysiologic information in patients with gastroparesis, in relation to symptoms, gastric emptying, and predicting the response to treatment directed at the pylorus.

RESUMO

Objetivo: evaluar los resultados terapéuticos de la aplicación de toxina botulínica A en pacientes con alteraciones espásticas palpebrales. Métodos: se realizó un estudio observacional, descriptivo, longitudinal y prospectivo en 18 pacientes con estas afecciones, seleccionados en la consulta de Oculoplastia del Instituto Cubano de Oftalmología Ramón Pando Ferrer en el período comprendido entre enero y diciembre del año 2016. Se describió la muestra según la edad, el sexo, el color de la piel, los antecedentes patológicos personales, las afecciones palpebrales y las limitaciones en tareas de la vida diaria. Se evaluó en el posoperatorio el tiempo de desaparición de los síntomas, la duración del efecto de la inyección de toxina botulínica, las complicaciones inmediatas y las mediatas. Resultados: el 70,6 por ciento estuvo comprendido en el rango de edad mayor de 60 años, y el 52,9 por ciento fueron mujeres. La piel blanca constituyó el 58,8 por ciento de la muestra. La afección que se presentó con mayor frecuencia fue el blefaroespasmo (47,1 por ciento). Todos los pacientes presentaron limitaciones para realizar tareas de la vida diaria. El 100 por ciento presentó dolor en el sitio de la inyección. En el 94,1 por ciento de ellos hubo desaparición de los movimientos involuntarios entre el cuarto y el quinto día posterior a la aplicación de xeomeen y en el 88,2 por ciento demoró la reaparición de los síntomas entre cuatro y seis meses. Conclusiones: la toxina botulínica es efectiva en la corrección de las afecciones palpebrales espásticas con desaparición de los síntomas en un período de tiempo entre cuatro y cinco días, con una rápida incorporación del paciente a la vida laboral y social por cuatro a seis meses(AU)

Objective: to evaluate the results of the treatment of thyroid orbinopathy and to determine the factors affecting them.Methods: observational study of a cohort of 82 patients with thyroid orbinopathy during the 1997-2009 period. Results: corticosteroid-bases therapy began nineteen months after the onset of disease and was unsatisfactory in most of cases with active thyroid orbitopathy, so it was necessary to perform several surgeries to preserve the vision. The influential factors on the therapeutic response were smoking and thyroid orbinopathy activity (OR= 30,479 and OR= 14,557, respectively). Good results were attained with botilinum toxin A and strabismus correction surgery and retraction. Conclusions: early diagnosis and treatment is the best therapy for patients with thyroid orbinopathy. Smoking and thyroid orbinopathy negatively affect the therapeutic response. Botulinum toxin A and surgery are effective options in the strabismus correction and palpebral retractions of thyroid orbinopathy(AU)

RESUMO

PURPOSE: To evaluate the efficacy of botulinum toxin type A injections in the detrusor muscle in patients with spinal cord injury and urinary incontinence due to detrusor overactivity and refractory to anticholinergic agents. MATERIALS AND METHODS: We prospectively evaluated 22 patients with spinal cord injuries, whose bladders were emptied by intermittent catheterization. All patients had detrusor overactivity and urinary incontinence that proved difficult to treat, despite using high doses of two different anticholinergics. The pre-treatment assessment included a complete urodynamic study and ultrasonography of the kidneys and urinary tract. A one-month follow-up was completed with urodynamic evaluation and the clinical response was evaluated through outpatient consultations and telephone contact. RESULTS: After the procedure, the maximum cystometric capacity and the bladder reflex volume increased, whereas the maximum detrusor pressure and compliance decreased. The mean duration of continence was 7 ± 7 months. In 18 patients (81.8 percent), it was necessary to administer anticholinergics to achieve continence. Five patients (22.7 percent) had indication of reinjection, and augmentation cystoplasty was indicated in 9 patients (40.9 percent). CONCLUSION: The use of botulinum toxin in the treatment of neurogenic detrusor overactivity refractory to anticholinergics is an option before more invasive treatments, such as augmentation cystoplasty, are attempted. In our study as well as in the literature, there was improvement in most urodynamic parameters. Overall, 40.9 percent of patients underwent augmentation cystoplasty and 81.8 percent of patients needed anticholinergic agents to reach urinary continence. Further studies are necessary to improve the procedure and to achieve better clinical results.
