Anal dilatation versus rubber band ligation for internal hemorrhoids: Method of treatment in outpatients

Of fifty-three consecutive patients with hemorrhoids referred to a rectal clinic forty-seven completed a trial designed to compare the results of anal dilatation with those of rubber band ligation.     

Medical students as teachers and role models for their future colleagues

Medical schools seldom involve students in applicant recruitment. The authors describe the role of junior medical students in recruitment at the University of Ottawa, aiming to increase the Franco-Ontarian applicant pool for the French-language medical program. The students have designed workshops reflecting their study program and offered them, since 1997, to 719 Ontario French-language high school students and to 291 francophone undergraduate university students. The workshops emphasize role modeling by medical students who act as physician-teachers while attendees act as medical students. Evaluation measures include attendee surveys, medical student focus groups and faculty admissions statistics. Attendees give uniformly positive evaluations, highlighting the importance of role modeling. Medical students find teaching enjoyable and highly educational. Admissions statistics show that the Franco-Ontarian applicant pool has more than doubled in spite of an almost fourfold increase in tuition fees. This experience has shown that junior medical student involvement in recruitment activities can benefit both the trainees and their institution.     

The effects of osmotic pressure on procaine-induced vacuolation in cell culture

The effect of increased tonicity on procaine-induced vacuolation in the H.Ep.2 cell has been investigated. An increase in tonicity equivalent to about 1·3% NaCl was found to reduce the formation of the drug-induced vacuoles and also to reduce established vacuolation. There appeared to be no difference in the effectiveness of the osmotic adjusting substances used (sodium chloride, sodium sulphate, glucose, fructose and sucrose) when employed in osmotically equivalent amounts.
