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.

Comparative Study Clinical Trial
Optic neuritis. Doppler ultrasonography compared with MR and correlated with visual evoked potential assessments.
To establish the role of Doppler ultrasonography (US) in the examination of patients with acute unilateral optic neuritis. ⋯ Doppler US can be used together with a VEP assessment as an indicator of the disease process in acute optic neuritis. These methods offer a potential for monitoring patients over time.

Randomized Controlled Trial Clinical Trial
Sedation versus general anaesthesia in paediatric patients undergoing chest CT.
CT of the chest in paediatric patients often requires sedation or general anaesthesia to minimize motion artefacts. Both sedation and general anaesthesia are associated with atelectasis which obscures the underlying pulmonary pathology. We conducted a prospective study to compare these two methods with respect to degree of motion artefacts and extent of atelectasis. ⋯ Whenever the clinical condition permits it, sedation rather than general anaesthesia should be given to paediatric patients undergoing chest CT.

Comparative Study Clinical Trial
Diagnosis of acute left-sided colonic diverticulitis by three radiological modalities.
To compare the findings at US, CT and contrast enema (CE) with the clinical, biochemical, and surgical findings in patients with suspected acute left-sided colonic diverticulitis (ALCD). ⋯ Radiological examination is valuable in confirming the diagnosis of ALCD. CT was the radiological modality that best demonstrated ALCD and revealed complications (e.g. pericolic abscesses) during the course of the illness.
