A survey of Canadian psychiatric residents regarding resident-educator sexual contact.

BACKGROUND AND METHOD: A survey of all Canadian psychiatric residents was undertaken to ascertain the prevalence of resident-educator sexual contact in training programs, the residents' feelings about this contact, their knowledge of the ethical standards of the profession, and the extent of the information they had been given about this subject. An investigator-designed questionnaire was circulated to all psychiatric residents in Canada through the directors of postgraduate training programs. To ensure confidentiality, the residents returned their questionnaires directly to the investigators. RESULTS: Of the 314 respondents, 4.1% (N = 6) of the female residents and 1.2% (N = 2) of the male residents reported sexual involvements with their educators. Although the majority of these eight residents had positive or neutral feelings about the contact, 37.5% (N = 3) of the involved residents had mixed feelings. The residents' education concerning resident-educator sexual contact was strikingly sparse. CONCLUSIONS: This study highlights the need for inclusion of this tissue in residency programs.

Newer emergency reperfusion techniques in acute myocardial infarction.

We have given an overview of the management of the acute myocardial infarction patient utilizing the aggressive reperfusion techniques available today. Anatomic reperfusion rates have been over 95% with the combined methods described. The remaining problems technically are those of earlier reperfusion, methods to enhance myocardial recovery after ischemia, and prevention of restenosis or reocclusion. The use of laser methodology, coronary sinus retroperfusion, partial left heart bypass, and other innovative strategies may improve these results. The introduction of tissue plasminogen activator will affect our approach and will profoundly alter society's expectations of therapeutic success. Still, patients will die from acute myocardial infarction and its complications. The search for a prevention must, therefore, not be overshadowed by our current enthusiasm for reperfusion techniques. Hopefully, our current approach will become a historical footnote as breakthroughs in preventive strategies occur.

The use of the guiding catheter in coronary angioplasty: the technique of manipulating catheters to obtain the necessary power to cross tight coronary stenoses.

We have examined a small selection of helpful maneuvers to facilitate passage of a balloon through tight stenoses. Selection of the appropriate guiding catheter is a critical early decision. Changing guiding catheters may be the most expeditious way to solve a "difficult case." The various options for deep engagement of the guiding catheter into the coronary orifice to gain power for crossing resistant lesions have been examined and the potential risks enumerated. The operator must be willing carefully to chart a course to avoid vessel occlusion, pressure damping, dye trapping, intimal damage, and dissection. Sudden disengagement of the guiding catheter from the coronary and vessel spasm must be prevented. Selective use of the "balloon traction maneuver," if judiciously applied, may lead to higher success rates. Guiding catheters and balloons will continue to evolve and hopefully become easier to use. The continued development of smaller deflated balloon profiles with slippery surfaces and better power transmission characteristics will undoubtedly make the vigorous techniques mentioned above less necessary to master in the future.
