ABSTRACT To describe the use of botulinum toxin type A (BTX-A) in radiation fibrosis syndrome (RFS).
Retrospective case series.
A large tertiary care cancer center.
Twenty-three consecutive patients treated for sequelae of RFS with BTX-A.
Not applicable.
A description of the components of RFS thought to benefit from BTX-A injections and the patient's self-report of benefit from those injections.
The sequelae of RFS for which BTX-A injection was thought to be indicated include radiation-induced cervical dystonia in 18 (78%), trigeminal nerve or cervical plexus neuralgia in 10 (43%), trismus in 7 (30%), migraine in 3 (13%), and thoracic pain in 1 (4%) patient. Most (87%) patients self-reported benefit from the injections.
Initial clinical experience with the use of BTX-A as adjunctive treatment for select neuromuscular and musculoskeletal complications of RFS in a variety of cancer patients has been encouraging. Well-designed prospective studies are needed to clarify the potential beneficial role of BTX-A in specific sequelae of RFS.

    ABSTRACT: The principle of leverage to superpose the convex surfaces of two shells was applied to develop a device for treating limitation of mouth opening and called it the "shell-shaped mouth opener" and analyzed pressure on the teeth with the TheraBite(®) appliance and the shell-shaped mouth opening appliance. To compare the TheraBite(®) appliance and the shell-shaped mouth opening appliance, pressure on the teeth in the dentition model with both devices was analyzed using the Inastomer(®) flexible conductive sensor. The load was better dispersed to each tooth in the shell-shaped mouth opening appliance in the all quadrants compared to the TheraBite(®) appliance. The present study revealed that the shell-shaped mouth opening appliance which was originally invented in our lab, dissipated the mechanical load on teeth more evenly than the TheraBite(®) appliance.

    ABSTRACT: Les douleurs cervicales sont présentes chez un tiers des patients après traitement d’un cancer des voies aéro-digestives supérieures. Elles sont secondaires à la radiothérapie ou à la chirurgie. Les cervicalgies ressenties sont invalidantes et les contractures musculaires limitent la mobilité cervicale. La toxine botulique de type A, par son action antalgique et myorelaxante, est susceptible d’améliorer la qualité de vie des patients. Nous rapportons notre expérience de l’utilisation de cette toxine dans le traitement des contractures cervicales post-radiochirurgicales. Patients et méthodes Il s’agit d’une étude pilote, monocentrique de janvier 2007 à juillet 2008 respectant les principes d’Helsinki. Tous les patients, en rémission complète d’un cancer ORL, qui souffraient de contractures cervicales post-radiochirurgicales avec une limitation de mobilité ont été inclus. La douleur et la gêne fonctionnelle ont été évaluées à l’aide d’une échelle d’incapacité cervicale avant injection et un mois après. La durée de l’efficacité a été notée. L’apparition de complications locales au point d’injection ou liées à la diffusion du produit a été recherchée. Résultats Neuf patients consécutifs ont été inclus, six hommes et trois femmes d’âge moyen 61 ans (52 à 73). Le muscle sterno-cléido-mastoïden a été injecté chez six patients et le pédicule musculaire d’un lambeau de grand pectoral chez trois patients. Le score moyen d’incapacité cervicale a diminué significativement de 33 à 23 (p = 0,01). Aucune complication n’a été rapportée. L’efficacité est apparue en moyenne en six jours. L’effet antalgique et myorelaxant a été de 19 jours en moyenne. Conclusion L’injection de toxine botulique dans les contractures cervicales post-radiochirurgicales est un geste simple et facile, susceptible d’améliorer la mobilité cervicale et de diminuer les cervicalgies des patients traités pour cancer ORL. Une étude prospective de phase 2 visant à mettre en évidence les sites d’injection et les doses de toxine à utiliser sera utile pour conforter ces données préliminaires.

    ABSTRACT: This review discusses the pathophysiology, evaluation, and treatment of neuromuscular, musculoskeletal, and functional disorders that can result as late effects of radiation treatment. Although radiation therapy is often an effective method of killing cancer cells, it can also damage nearby blood vessels that nourish the skin, ligaments, tendons, muscles, nerves, bones and lungs. This can result in a progressive condition called radiation fibrosis syndrome (RFS). It is generally a late complication of radiotherapy which may manifest clinically years after treatment. Radiation-induced damage can include “myelo-radiculo-plexo-neuro-myopathy,” causing muscle weakness and dysfunction and contributing to neuromuscular injury. RFS is a serious and lifelong disorder which, nevertheless, may often be decremented when identified and rehabilitated early enough. This medical treatment should be a complex procedure consisting of education, physical therapy, occupational therapy, orthotics as well as medications.
