Abstract
OBJECTIVES
To study the clinical and neuroelectrophysiological features of botulism in children.
METHODS
A retrospective analysis was conducted on the clinical data of eight children who were diagnosed with botulism in the Department of Neurology, Hunan Children's Hospital, from August 2015 to October 2022.
RESULTS
All eight children were found to have symmetrical cranial nerve palsy and flaccid paralysis of the extremities, with a descending pattern. Seven children presented with respiratory muscle paralysis. Electrophysiological examinations revealed decreased compound muscle action potential (CMAP) amplitudes in 5 children, increased CMAP amplitudes exceeding 40.0% in 6 children during high-frequency repetitive nerve stimulation, and short duration, low amplitude, and polyphasic motor unit action potentials in 4 children.
CONCLUSIONS
The main clinical features of botulism in children include symmetric, descending flaccid paralysis starting from cranial nerves, with the possibility of respiratory muscle paralysis. Electrophysiological abnormalities associated with it include decreased CMAP amplitudes, increased CMAP amplitudes during high-frequency repetitive nerve stimulation, and short duration, low amplitude, and polyphasic motor unit action potentials.
