title: [Recurrent bronchopneumopathies in the infant due to swallowing dyspraxia. Two cases].
abstract: In two infants with recurrent lower respiratory tract infections starting within a few weeks of birth, dynamic electromyographic studies of sucking and swallowing evidenced a disorder of lingual and pharyngeal activities responsible for the episodes of aspiration. The central location of the anomaly was demonstrated by the absence of peripheral neuromuscular anomalies and by the presence of impaired blinking reflexes and brain stem potential anomalies. These neurofunctional anomalies improved over time and magnetic resonance imaging failed to disclose and structural anomalies of the central nervous system. The occurrence of the swallowing disorder as an isolated manifestation and its long duration, with follow-ups of 23 months and 4 years, are two unique features in these cases. Neurophysiologic investigations are essential for documenting the neurologic etiology of the swallowing disorders, demonstrating their location above or within the medulla oblongata, and differentiating functional and organic anomalies.
