Duplex scanning with the use of continuous wave Doppler instrumentation was used for the evaluation of carotid disease and compared to angiography. In twenty such patients 100% accuracy for diagnosis of total occlusion by Duplex scanning with continuous wave Doppler, was obtained. The sensitivity for those patients with 50%-99% stenosis was 92% and for those patients with 20%-49% stenosis was 75%. The overall accuracy for this diagnostic test for all groups of stenosis was 85%. This compares favorably with other noninvasive vascular techniques and is felt to be an accurate and useful technique for the detection of carotid stenosis. Several advantages of this technique are pointed out.

There is much support for health promotion in Canada, but not much is known about the various academic programs in this field or of their impact on the practice of community health. A census survey was conducted in 1991 to determine the career paths of graduates of the MHSc program in Health Promotion at the University of Toronto. Findings from the study indicate that the career paths of graduates change following completion of their degree. They are more likely to work in health organizations other than hospital or treatment settings, to have more responsibility and authority in their positions as reflected by changes in job titles and to utilize a wider range of health promotion strategies and methods in their work following graduation. The findings indicate that graduate training in health promotion has a positive effect on the planning, implementation and evaluation of community health programs.
