To describe and to analyze cervical epidural contrast patterns seen in antero-posterior (AP), contralateral oblique (CLO), and lateral view. To identify factors that might help in predicting contrast distribution pattern and extent. ⋯ The CLO view provides a consistent radiological landmark for the posterior margin of contrast in the dorsal epidural space; the lateral view fails to provide such a consistent landmark. The thickness of the spread is variable, both in the CLO and in the lateral view. Thick spread extending into the foramen in the CLO view and over the articular pillars in the lateral view is frequent and should not be misconstrued as subdural or intrathecal spread. In contradistinction to previous studies, true ventral spread was not seen in any patient. When using low volumes, contrast spread is independent of patient age, volume injected, or needle tip location in the AP view.

Although the University of Toronto Centre for the Study of Pain has successfully implemented an Interfaculty Pain Curriculum since 2002, we have never formalized the process in a design model. Therefore, our primary aim was to develop a model that provided an overview of dynamic, interrelated elements that have been important in our experience. A secondary purpose was to use the model to frame an interactive workshop for attendees interested in developing their own pain curricula. ⋯ The Pain Interprofessional Curriculum Design Model is based on established pain curricula and related competencies that are relevant to all health science students at the prelicensure (entry-to-practice) level. The model has been developed from our experience, and the components resonated with workshop attendees from other regions. This Model provides a basis for future interventions in curriculum design and evaluation.

Based on several previous clinical studies, we hypothesized that ornithine levels are different among subjects with persistent musculoskeletal pain compared with other subjects in the population. ⋯ Ornithine levels are elevated in general population subjects with persistent pain.
