Teaching methods
The course consists of lectures and analysis/discussion of clinical case reports, with the help of iconographic material, partially made available on UniMI computer platforms. Quiz and classroom surveys using computer platforms to review the most important topics. The consultation of the material presented during the lectures does not replace the study on textbooks.
