ABSTRACT
We describe a 30-year-old pregnant woman with undiagnosed weakness who delivered a severely weak neonate. Subsequent workup of the mother revealed myasthenia gravis with muscle-specific kinase antibodies. The infant responded to intravenous immunoglobulin and symptoms normalized. He was presumed to have an anti-muscle-specific kinase-mediated transient neonatal myasthenia gravis.

ABSTRACT
A patient with muscle cramps was referred for nerve conduction studies and electromyography. Her study demonstrated bursts of spontaneous electromyography activity, which waxed and waned in amplitude with a "dive bomber"-like sound. The abnormal finding was found to be an artifact from an implanted sacral nerve stimulator for bladder incontinence.
