Telebrix: a better-tasting oral contrast agent for abdominal computed tomography.

In a randomized, controlled, double-blind trial, Telebrix 38 (ioxithalamate) and Gastrografin (diatrizoate) were compared with respect to taste and degree of opacification of the alimentary canal when used in computed tomography of the abdomen and pelvis. Bowel opacification was excellent with both contrast agents. Patients rated the 2% solution of Telebrix in water significantly better in taste than the control contrast medium, a 2% solution of Gastrografin in water. Of the patients in the Telebrix group 89% judged the taste to be excellent or good, compared with 59% in the Gastrografin group (p = 0.012, Fisher's exact test). Only 1 of 28 patients in the Telebrix group was unwilling to drink Telebrix again, compared with 6 of 27 patients in the Gastrografin group (p = 0.045, Fisher's exact test). There were no significant side effects. Dilute Telebrix 38 is preferable to dilute Gastrografin, in terms of taste and patient tolerance, for bowel opacification on computed tomography, and produces equivalent, excellent bowel opacification.

An integrated team approach to the management of patients with oropharyngeal dysphagia.

This paper describes a team approach to the assessment and management of patients with oropharyngeal dysphagia of neurologic origin. The team's major focus was to determine the need for adjustments to the patient's diet to maintain or restore the safety of oral feeding. This involved the development of a detailed radiographic examination and a series of dysphagia diets, in addition to comprehensive evaluations by an occupational therapist, physiotherapist, and speech pathologist. The effects of deteriorating swallowing ability on the physical, cognitive, and emotional status of the patient are discussed in the context of a multidisciplinary approach.

Digital teleradiology: Seaforth--London network.

A total digital teleradiology system using a prototype DuPont laser beam scanner (DTR 2000) and a Bell Canada digital transmission network was evaluated. A total of 489 radiographic and ultrasonographic examinations were transmitted for interpretation from a 41-bed rural community hospital in Seaforth to the University Hospital in London, Ontario, 80 km away. There was concurrence in 98% of these examinations, i.e. the laser-sensitive facsimile film clearly duplicated the original film findings and allowed a confident interpretation to be made. We conclude that this system could readily serve the needs of family physicians in rural communities for radiologic consultation, diagnosis, management, and triage of patients 24 hours per day.

Single-contrast examination of the duodenum following enteroclysis.

Important abnormalities of the distal duodenum can be missed on the usual enteroclysis examination because of placement of the intubation tube beyond the ligament of Treitz. This can be avoided by extending the examination to include visualization of the duodenum during withdrawal of the nasojejunal tube. On the basis of the case reported here this procedure is suggested for patients with unexplained upper gastrointestinal bleeding in whom the remainder of the small bowel is normal.
