The founding of the first psychiatric hospital in the World in Valencia.
(65/201)
Several hospitals, countries and cultures claim the privilege of being the first to have provided care to people suffering mental illnesses. Among them, the <> (Hospital of the Innocents) founded in Valencia in 1410 stands out due to its originality and there are historic and cultural reasons to recognize its primacy. Furthermore, the organization and functioning of this institution and the model, spread like wildfire through the entire Iberian Peninsula during the 15th Century and shortly after through American Spanish speaking countries. For centuries, these establishments were considered exemplary and were copied in other European Countries. At the beginning of the 19th Century in Spain a forced sale of the Catholic Church properties or their disamortization among other a large number of hospitals establishments took place. This lead to a terrible collapse of health care for the mentally. From then on it took more than one century to recover a decent standard. The vicissitudes of the creation and progress of the hospital of Valencia and others which followed the example that allows to affirm that it was really the first psychiatric hospital in the World are analyzed in this present work.

Leonardo da Vinci and the first hemodynamic observations.
(69/201)
Leonardo da Vinci was a genius whose accomplishments and ideas come down to us today, five centuries later, with the freshness of innovation and the fascination of discovery. This brief review begins with a summary of Leonardo's life and a description of the most important works of art that he bequeathed us, and then concentrates on his last great challenge. There was a point at which Leonardo's passion for art gave way to the study of human anatomy, not only to improve his drawing but to go beyond what had been simply a representation of form to understand the underlying functioning. Among his many interests, we focus on his study of the heart and blood vessels, which he observed carefully in animals and human autopsies, and reproduced in drawings of great quality with annotations of astonishing acuteness. The experience that he had acquired from observing the flow of water in currents and around obstacles, and the conclusions that he drew concerning hydrodynamics, were central to his interpretation of the mechanisms of the heart and of blood flow, to which he devoted much of his time between 1508 and 1513. From these studies, immortalized in drawings of great clarity, come what are acknowledged to be the first hemodynamic records, in which Leonardo demonstrates the characteristics of blood flow in the aorta and great vessels and the importance of blood reflux and the formation of eddies in the sinus in aortic valve his assiduous and careful observations, and his subsequent deductions, Leonardo put forward detailed findings on hemodynamic questions that advanced technology has only recently enabled us to confirm.
