| The most important component of the upper esophageal sphincter (UES) is the cricopharyngeal muscle. During the measurement of sphincter pressure the catheter passed through the sphincter affects the pressure value. In Chagas' disease and primary achalasia there is an esophageal myenteric plexus denervation which may affect UES pressure. We measured the UES pressure of 115 patients with Chagas' disease, 28 patients with primary achalasia and 40 healthy volunteers. We used a round manometric catheter with continuous perfusion and the rapid pull-through method, performed in triplicate during apnea. Pressures were measured in four directions, and the direction with the highest pressure (anterior/posterior) and the average of the four directions were measured.... |

| ABSTRACT: Megaesophagus is a rare disease in ruminants characterized by regurgitation of rumen contents. In this paper it was described cases of megaesophagus in two sheep and two goats on a farm in the state of Paraíba, Northeastern Brazil. All animals showed regurgitation of rumen contents and weight loss, with a clinical course of several months. At necropsy all animals presented megaesophagus. Histological examination showed segmental muscle necrosis in the esophagus and skeletal muscles. Serum samples from one sheep and one goat were negative for the presence of blue tongue antibodies by ELISA, and whole blood and muscle samples from one goat were negative for this virus by RT PCR. Epidemiological data and pathology suggested that the disease could... |
