Myokymia of the tongue is a very rare clinical condition and is much less common than facial or focal myokymia of the limbs. Radiation-induced delayed nerve damage is a well-known cause of myokymia, but other etiologies i.e. tumor recurrence should be considered as a differential diagnosis. We describe a case series of neurophysiologically proven unilateral tongue myokymia, which arose in two p...

BACKGROUND Isolated unilateral hypoglossal nerve injury is extremely rare. It may be caused by radiation therapy targeting neoplasms of the cephalic region. CASE REPORT A 51-year-old man with synovial sarcoma of the left upper arm status post extensive radiation therapy in 1980 presented in late 2014 with gradual onset of speech difficulty and difficulty moving his tongue for a couple of weeks....

The actions of ethanol (EtOH) on the respiratory output of the neonatal rat brain stem slice preparation in vitro are described. Ethanol inhibited respiratory-related hypoglossal nerve activity in a dose-dependent manner. The effect of EtOH was evident within 5 min and was reversible on EtOH washout. The actions of EtOH were qualitatively similar to those of two other alcohols, methanol and oct...

Objectives/Hypothesis The time course of the reinnervation of the paralyzed face after hypoglossal-facial jump nerve suture using electromyography (EMG) was assessed. The relation to the clinical outcome was analyzed. Study Design Retrospective single-center cohort study. Methods Reestablishment of motor units was studied by quantitative EMG and motor unit potential (MUP) analysis in 11 pat...

First published June 27, 2013; doi:10.1152/japplphysiol.00423.2013.—Obstructive sleep apnea is characterized by recurrent episodes of pharyngeal collapse, which result from a decrease in pharyngeal dilator muscle tone. The genioglossus is a major pharyngeal d...
