[Evaluation of remission in childhood myasthenia gravis].

By the electrophysiological methods such as supramaximal stimulation and single-fibre EMG (SF EMG) 13 children with myasthenia were studied. In only one case the results of both tests were normal. These findings confirm the presence of subclinical disturbances of neuromuscular transmission in most cases of myasthenia during remission. This may be of practical importance in the treatment of myasthenic patients.
