Mechanisms in Medicine are key to explain diseases based on anatomy and physiology. This static view of the human body is practical for teaching but the body is not a perfect machine designed by an engineer. Evolution has played its role.

The knowledge of these particularities can help to fix concepts and to improve clinical reasoning.

A brochure elaborated by Geeta Singhal, MD, presented at The 7th International Conference of Diagnostic Error in Medicine. A clear and nice summary of the most important cognitive bias in clinical reasoning and key references.
Mind mapping, developed by Tony Buzan, is a method to show information selecting key words or, in Medicine,key signs or symptoms in a graphic way, looking for a better description and an easier way of learning. I have to confess that I,ve never seen this method in the everyday teaching but I think is worth considering…
We have discussed the clinical findings from a patient diagnosed of ovarian cancer. The patient stayed at the hospital due to dyspnea in relation to pleural effussion, edema in both legs and fatigue. The first diagnostic possibility considered was ovarian cancer progression but the students make an exercise of differential diagnosis using numbers from 1 (less probable) to 5 for several possibilities.
