Comparative Study
Videomanometry of the pharynx in dysphagic patients with laryngeal barium penetration during swallowing.
This study used simultaneous videomanometry to measure pressure characteristics in a group of patients with evidence of laryngeal and/or tracheal barium penetration, and to compare the results to those of one group of healthy volunteers and one group of patients with dysphagia but a normal barium swallow. ⋯ The differences in manometric abnormalities between patients with laryngeal penetration and patients with normal barium swallows may be useful in identifying the mechanisms of laryngeal penetration.

To describe and discuss the thoracic CT features of hypovolemic shock. ⋯ In patients with hypovolemia, CT may show several thoracic findings in addition to abdominal ones. Knowledge of these features is important for distinguishing them from traumatic injuries.
