This book is a collection of articles. Illustration of our post-doctoral scroll. It is the work of the support of many of our professors and the collaboration with several colleagues. The majority of the articles it contains have already been published in scientific journals. Some are in the process of being published. It summarizes our first experiences in medical writing. It does not claim to be perfect and no work, if not human, is perfect. These are our first steps in a sea of scientists, writers and practitioners. We let the sap of medical literature rise progressively through the soles of our feet, immersed in this ocean, to our right and left brains and then to our whole body through your contributions and judgments of this first step for better progress in the future.
