[Postgraduate studies in the medical field].

Considerations on a few aspects of postgraduate education in medicine are made: 1) Concept of stricto sensu of postgraduate study of the physician (who is an MD and seeks a second degree of doctor, that is, the PhD); 2) Importance of scientific initiation (to shorten stricto sensu postgraduation); 3) Features of the postgraduate program (that, having the objective of preparing a scientific investigator, has different characteristics of the graduation courses, of specialization or advanced courses, of the advisor (who must have a consistent line of research), of the doctor-to-be (who must develop his potential of creativity) and of the thesis to be prepared (which should generate a paper publishable in an indexed international journal).
