Medical students' perceptions of pathology and the effect of the second-year pathology course.

To explore the perceptions of medical students regarding pathology and the effect of the sophomore pathology course, a questionnaire was given to second-year students from 5 different medical schools at the beginning and again at the completion of their pathology course. The questionnaire was given to students in the class of 1995 and then again for those in the class of 2002, with nearly 1,500 surveys collected over the study period. The survey included questions that sought to determine students' affinity for pathology, their understanding of the typical duties of a pathologist, and how they viewed pathology relative to other specialties and perceived positives and negatives of being a pathologist. Overall, the second-year pathology course had little effect on medical students' perceptions of pathology but did provide some increase in their understanding of pathology as a profession. Responses were in general stable when comparing the different classes. Those students interested in pathology emphasized the intellectual aspects of pathology although being less deterred by negative factors such as limited patient contact. In our sample of medical schools, the sophomore pathology course was ineffective at influencing students' perceptions of pathology. Furthermore, those students who are interested in pathology are drawn because of a perceived fit between their personalities and the perception of pathology as a solely scholarly and isolated specialty. Better education about the practice of pathology in the second year, and more importantly, continuing into the clinical years, is necessary to combat these misconceptions about pathology.

Should plasma be transfused prophylactically before invasive procedures?

PURPOSE OF REVIEW: Plasma transfusion to correct abnormal coagulation test results prior to an invasive procedure is a common clinical practice; however, there are no evidence-based guidelines. This review aims to analyze the most recent publications to either support or disprove such practice. RECENT FINDINGS: Due to heightened awareness of transfusion-related acute lung injury and volume overload in susceptible patients, clinicians are increasingly questioning the validity of prophylactic plasma transfusion. Recently, several articles, reviews and clinical studies (although small and poorly designed) have shown no benefit of prophylactic plasma transfusion in either correcting abnormal coagulation tests or reducing perceived risk of hemorrhage. SUMMARY: The use of sensitive reagents (especially for prothrombin time) has resulted in increased incidence of abnormal preprocedure coagulation screening test results - tests that are not designed to assess risk of bleeding in patients without a history of bleeding. Transfusion of plasma prior to an invasive procedure to correct mild to moderate abnormal test results neither corrects the abnormality nor reduces the perceived bleeding risk.
