title: Botulinum neurotoxin A: an unusual systemic effect.
abstract: Systemic effects from Botulinum neurotoxin A are uncommon but can have serious consequences. We report the case of a boy with severe cerebral palsy who developed deterioration in respiratory and oromotor function following repeated injections of Botulinum neurotoxin A. Caution is needed in using this treatment in children with severe cerebral palsy and pseudobulbar palsy.
