Dysphagia with fatal choking in oculopharyngeal muscular dystrophy: Case report.

rationaleOculopharyngeal muscular dystrophy (OPMD) is an autosomal dominant late-onset progressive muscle disorder typically characterized by ptosis, difficulty in swallowing, and proximal limb weakness. Underdiagnosis of OPMD is common in Asian countries and results in delayed diagnoses and fatal events. PATIENT CONCERNS: Here, we report the case of a 53-year-old female who suffered from progressive dysphagia and experienced several choking events involving solid material. An extensive family history of dysphagia was noted, and 2 family members had died as a result of aspiration. DIAGNOSES: PABPN1 genotyping and DNA sequence analysis revealed a heterozygous (GCG)10(GCA)3GCG mutation that led to the diagnosis of OPMD.

interventionsRehabilitation exercises, namely, the Shaker exercise and the Masako maneuver, were suggested. OUTCOMES: Improved swallowing ability with safe food intake was noted after 2 months of training. Surgical intervention will be considered when progression of the disease is noted. LESSONS: Underdiagnosis and a lack of awareness of OPMD may lead to choking, aspiration pneumonia, and death in multiple members of affected families. Currently, there is no definitive treatment for OPMD, but rehabilitation exercises and surgical intervention are helpful in relieving dysphagia.
