[Manometrical study of the pharynx and the pharyngoesophageal sphincter in patients with polymyositis].

The purposes of this paper are to evaluate degree of dysphagia at the pharyngeal stage of swallowing in patients with polymyositis. A catheter with three diode transducers 5 cm apart was swallowed through the nose into the upper esophagus. Firstly a patient was commanded to drink water of 2 ml at about five second intervals, and the swallowing pressures were recorded on condition that the speed of paper recording and catheter pull-through is the same 1 mm/sec.

A 60 year-old Japanese man having a 20-year history of diabetes mellitus presented with truncal neuropathy. The severe pain, especially its nocturnal exacerbation, prevented him from sleeping and eating, resulting in rapid emaciation.

[Manometric study of the pharynx and pharyngoesophageal sphincter in myasthenia gravis].

The purposes of this paper are to evaluate degree of dysphagia at the pharyngeal stage of swallowing in patients with myasthenia gravis (Osserman IIB). A catheter with three diode transducers 5 cm apart was swallowed through the nose into the upper esophagus.
