Adapting Human Videofluoroscopic Swallow Study Methods to Detect and Characterize Dysphagia in Murine Disease Models
Published on: March 1, 2015
Ultrasonographic evaluation of piecemeal deglutition in normal adults
Objectives:
To evaluate the range of multiple swallowing in normal subjects by ultrasonography.
Methods:
Twenty-two normal subjects swallowed 5 or 10 ml of tap water or a semisolid meal.
Results:
With water multiple swallows were seen in 41% of the subjects examined and was related to the volume of the bolus:18% of the cases were 5 ml and 36% were 10 ml. Sixty-eight percent of subjects had multiple swallows with semisolid boluses.
Conclusion:
These results differ from those reported with videofluoroscopy of modified barium swallowing. Ultrasonography should be used in future studies of normal and pathological oral swallowing.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
