There are still patients which use obsolete medical terms. People's terminology, rather than the modern terminology, is often used to describe symptoms or diseases. Medical terms can also be replaced with terms inherent to patient's own culture. Seen from this perspective, the knowledge of the former medical terms and the terms used colloquially is very helpful for doctors. The purpose of this study was to investigate the knowledge of former medical terms among the medical students. This study was performed on 102 students of medicine faculty. Students, who gave their consent, were interviewed in a face-to-face fashion. The results of the survey were statistically analyzed.
