A Moment in History

Jean-Louis Petit

Jean Louis Petit
(1674 – 1750)

French surgeon and anatomist, Jean Louis Petit was born in Paris in on March 13, 1674.  His family rented an apartment at his house to Alexis Littre (1658 – 1726), a French anatomist. Petit became an apprentice of Littre at seven years of age, helping him in the dissections for his lectures and at an early age became the assistant in charge of the anatomic amphitheater.

Because of Petit’s dedication to anatomy and medicine, in 1690 at the age of sixteen, became a disciple of a famous Paris surgeon, Castel.

In 1692, Petit entered the French army and performed surgery in two military campaigns. By 1693 he started delivering lectures and was accepted as a great surgeon, being invited to the most difficult operations.  In 1700 he was appointed Chief Surgeon of the Military School in Paris and in the same year he received the degree of Master of Surgery from the Faculty of Paris.

In 1715 he was made a member of the Royal Academy of Sciences and an honorary member of the Royal Society of London. He was appointed by the King as the first Director General of the Royal Academy of Surgery when it was founded in 1731.

Petit’s written works are of historical importance.  “Traite des Maladies des Os” ( A Treatise on Bone Diseases);  “Traite des Maladies Chirurgicales et des Operation” (A Treatise on Surgical Diseases and their Operations” This last book was published posthumously in 1774. He also published a monograph on hemorrhage, another on lachrymal fistula, and others.

He was one of the first to perform choIecystotomy and mastoidotomy. His original tourniquet design for amputations saved many in the battlefield and the design of the same surgical instrument today has not changed much since its invention by him.

His name is remembered in the lumbar triangle, also called the "triangle of Petit", and the abdominal hernia that can ensue through that area of weakness, the lumbar hernia or "Petit's hernia".

Glossary of Terms for Thoracic Imaging

Published: Wednesday, September 20, 2017 07:00 | Written by: Prof. C. Uribe

One of the current challenges in medical sciences is to achieve a common and universal language that allows establishing, promoting the understanding and communication between people of different cultures and nationalities.

The use of anatomical and radiological terms in the chest is not exempt from this theme. An adequate terminology allows describing findings and unifying concepts that facilitate communication, teaching, research, in brief, the transmission of knowledge.

From the radiological point of view, ignorance of appropriate terminology creates confusion and may eventually lead to inaccuracies and misdiagnoses. Therefore, reaching consensus in terminology is an attempt to minimize the effects of language vices, which are unfortunately passed on to future generations.

On the other hand, in recent years, technical advances in radiology have improved the capture, recording and storage of images, which in turn has involved the need for a new language to explain new concepts.

 Fleischner
Felix Fleischner, MD
Within this context, the Fleischner Society, an international and multidisciplinary medical society for thoracic radiology, was founded in 1969 in memory of Dr. Félix Fleischner. Among the objectives of this society is the publication of formal statements that have been adopted for several years, as standards in the field of chest radiology, generating an important point of discussion and consensus around this issue.

Thus, as in 1971 a proposal for initial terminology was made, which was consolidated in 1984 and 1996 with the publications of the Fleischner Society glossary for Chest X-rays and Tomographies respectively. In 2008 (Radiology 2008; 246: 697-722) this glossary is finally updated using new terms, modifying or eliminating some of those that have become obsolete and others in which their meaning has changed.
