Myasthenia gravis.

Twelve children with myasthenic symptoms were seen over a period of 6 years. The age of onset of symptoms ranged from 6 months to 9 years. On followup for a mean period of 4.25 years, (longest followup was 9 years) five children went into complete remission of symptoms after treatment with prostigmine; three children responded to prostigmine and steroids; two children were relieved of symptoms without prolonged treatment and the remaining two children could not be followed up. Thymectomy was not advised in any patient.
