Silent dysphagia in two patients with Steinert disease and recurrent respiratory exacerbations.

Abstract

We describe two cases of patients with Steinert's dystrophy or myotonic dystrophy type 1 (DM1) who presented with frequent respiratory exacerbations and pneumonia. They did not report any risk factors for asthma, allergy, bronchopathy or dysphagia in their history. The Videofluoroscopic swallow study test allowed to highlight post-swallowing aspiration phenomena responsible for respiratory exacerbations.
