Hemifacial spasm: an electrophysiological evidence of facial motorneurons hyperexcitability.

Twenty patients with primary hemifacial spasm and ten patients with Parkinson's disease were studied by means of paired stimuli blink reflex. The second stimuli were delivered at a varying time interval between 50-900 ms. The R2 response's absolute refractory periods were compared between patients and twenty one age-matched normal controls as well as between hemifacial spasm and Parkinson's disease.

The correlation of the short latency somatosensory evoked potentials and the strokes disability.

Median and tibial short latency somatosensory evoked potentials (SSEPs) were studied in 54 stroke patients, 27 males and 27 females. Thirty-two patients had cerebral infarction and 22 had cerebral hemorrhage. Median SSEPs abnormalities correlated with the Barthel score (p = 0.

Muscular dystrophy with particular oculopharyngeal involvement.

The authors report the case of 33-year-old woman who presented with a 20 year history of external ophthalmoplegia with later involvement of pharyngeal and proximal muscles. Tensilon test excluded myasthenia gravis. Electromyography showed myopathy and muscle biopsy showed evidence of mitochondrial myopathy.
