ABSTRACT

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 therapeutic results of the application of toxin botulínica A in patients with palpebral spastic alterations. Methods: an observational, descriptive, longitudinal and prospective study was performed on 18 patients with these conditions, who were selected at the Oculoplasty Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology in the period from January to December 2016. The analyzed variables were age, sex, race, personal pathological history, eyelid disorders and restricted daily life. In the postoperative period, length of time for symptom relief, duration of the effect of botulinum toxin injection, and immediate and mediate complications were assessed. Results: in the group, 70,6 percent were included in the over 60 y age group and 52,9 percent were women. Caucasians accounted for 58,8 percent of the sample. The most frequent condition was blepharospasm (47,1 percent). All patients had limitations to perform daily life tasks. In 94,1 percent of the patients, involuntary movements disappeared between the 4th and the 5th day after the administration of Xeomeen and in 88,2 percent, the symptoms delayed to appear again from 4 to 6 months. Conclusions: botulinum toxin A is an effective alternative to correct palpebral spastic conditions, with symptoms disappearing in four to five days, and quick reincorporation of the patient to working and social life for 4 to 6 months(AU)

ABSTRACT

O blefaroespasmo essencial é uma distonia focal caracterizada por contrações involuntárias, espasmódicas e bilaterais dos músculos orbicular da pálpebra, corrugador, prócerus e depressor do supercílio. Trata-se de uma doença rara, cujo diagnóstico é frequentemente tardio, o que permite a progressão dos sintomas até quadros de cegueira funcional. Nesse estudo, por meio de revisão da literatura, descreve-se as principais características da doença, incluindo os seguintes aspectos: histórico, epidemiologia, etiologia, quadro clí­nico, diagnóstico diferencial e tratamento.


Essential blepharospasm is a focal distonia characterized by involuntary, spasmodic, bilateral contractions of eyelid protractors. This is a rare disease, which diagnosis is frequently late and symptoms may progress until functional blindness. In this article, we perform a review and describe the most important features of the disease, including historical aspects, epidemiology, etiology, clinical findings, differential diagnosis and treatment.

ABSTRACT

O blefaroespasmo é uma forma de distonia focal caracterizada por contraçöes involuntárias e repetitivas do musculo orbicular dos olhos. Quatorze casos de blefaroespasmo foram submetidos a injeçöes de toxina botulinica tipo A. Dos 14 casos estudados, seis eram do sexo masculino e oito do sexo feminino, sendo que 50 por cento dos pacientes apresentavam a forma isolada do BE e em outros 50 por cento a distonia estendia-se a outros territorios musculares na regiäo cervical ou cranial. A media de idade era de 58 anos (variando de 33 a 76 anos) e a duraçäo média da doenba de 7,3 anos (com extremos de 1 a 25 anos). Todos haviam sido tratados com drogas de acao antidistonica com resultados insatisfatorios. Cinco pacientes haviam sido submetidos a neurectomia superseletiva do nervo facial, com melhora transitoria. Em todos os pacientes do grupo a resposta a toxina botulinica, avaliada atraves de escalas especificas, foi considerada boa. O periodo de latencia para o inicio da resposta foi em media de tres dias (com faixa de 0 a 7 dias)...

ABSTRACT

Dystonia is a neurologic disease characterized by involuntary repetitive muscular contractions which frequently causes torsion, spasmodic movements or abnormal postures. Pharmacologic and surgical treatment had been unsatisfactory in the majority of the cases. Intramuscular botulinic toxin application in focal dystonia disorders, achieve relief in approximately 90% of the cases by quimiodenervation. We included 35 patients with focal dystonia treated between November 1994 through June 1996: 14 facial hemispasm, nine blepharospasm, five cervical dystonia, two writer's cramps, one oromandibular dystonia and four patients with mixed focal dystonia. Improvement between 50-90% was observed in 32/34 (94%) of the patients; one case (2.8%) with therapeutic failure and one case (2.8%) never returned to quantify the response. Actually, botulinic toxin is the first choice treatment of focal dystonia and other diseases related to involuntary muscle spasm

ABSTRACT

Se revisaron las historias clínicas de 234 pacientes con diagnóstico de blefaroespasmo (BE) (68) y espasmo hemifacial (EH) (166) que fueron infiltrados entre 1987 y 1995 en el Servicio de Neurología del Hospital de Clínicas de la ciudad de Buenos Aires. De los pacientes con EH, 55 fueron varones y 111 mujeres, con una edad promedio de 57,5 años, mientras que 17 varones y 51 mujeres presentaron BE/BE-distonía oromandibular con una edad promedio de 63 años. La edad general de comienzo fue de 56,3 años para los EH y 56,8 para los BE. Trece EH fueron postparalíticos, dos secundarios a tumores de tronco, uno secundario a una lesión vascular protuberancial y uno a enfermedad de Paget, el resto fueron diagnosticados como primarios, aunque en las IRM y TC cerebrales resultó evidente en muchos de ellos la presencia de ectasias en el circuito vertebrovasilar. La dosis promedio en pacientes con EH fué de 21,8 I.U. con un rango entre 12,5 I.U. y 50 u, mientras que la dosis promedio en pacientes con BE fué de 33,1 con un rango entre 25 y 75 u. El número total de infiltraciones fué de 1910 con un promedio de 9,8 para los EH y 5,5 para los BE. La duración promedio del efecto beneficioso de cada dosis fué de 3 meses para ambos grupos. Todos los pacientes se beneficiaron marcadamente (77 por ciento) y moderadamente (27 por ciento) con las infoltraciones aunque el 12,5 por ciento experimentó una ptosis transitoria como efecto colateral en algunas de las aplicaciones. Los pacientes con BE requirieron un incremento progresivo de un 21 por ciento de la dosis de toxina botulínica a lo largo de todo el tratamiento, mientras que en los EH se necesitó un 20 por ciento de aumento. Nuestra experiencia ilustra la utilidad de la toxina botulínica en el manejo del EH y el BE constituyendo un arma terapéutica sencilla y eficaz que debe ser considerada como el tratamiento de elección en este tipo de patología

ABSTRACT

As an alternative to conventional medical and surgical modalities that have met little success in the treatment of paralytic strabismus and essential blepharospasm, we explored the use of botulinum toxin as a treatment of choice in these two disorders. We used botulinum toxin in three patients with paralytic strabismus and in nine patients with essential blepharospasm. In three patients with paralytic strabismus, the botulinum toxin was injected into the ipsilateral antagonist of the paralysed muscle. The preinjection deviations ranged from 18 to 60 prism diopters. Two of these three patients achieved orthotropia around the thirtieth day and thereafter maintained it. The third patient became orthotropic on the eighteenth day, but deviation recurred and therefore required another injection of toxin. In nine patients with essential blepharospasm, botulinum toxin was injected into the orbicularis oculi muscles. Both objective and subjective improvement occurred in all nine patients within seven days and the effect lasted 12 to 15 weeks. Further injection of the toxin produced extremely beneficial results. However, the only significant complication that we encountered in both groups of strabismus and blepharospasm was ptosis, which was usually partial and temporary. From our experience, we advocate the use of botulinum toxin in the treatment of essential blepharospasm.

ABSTRACT

We describe our experience with the use of botulinum A toxin for the treatment of patients with facial spasms. Thirty four patients with blepharospasm, thirty eight with hemifacial spasms and three with spastic entropion were injected with the use of Botulinum A toxin. Length of follow up ranged from 6 to 60 months. The effect of toxin lasted an average of 12.1 weeks in patients with blepharospasm and 15.5 weeks in patients with hemifacial spasms. This difference in mean response was statistically significant (p = 0.0001). The most common side effect was ptosis and dry eyes. All side effects were transient in nature, lasting between three and twelve weeks. Botulinum toxin type A injections represent a good alternative for the treatment of facial spasms. It is a safe and effective office procedure. Most patients tolerate the procedure well. Its principal drawback is its transient effect and the need for repeated injections
