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".

Hygiene

Published: Tuesday, January 07, 2014 07:00 | Written by: Efrain A. Miranda, Ph.D. | Hits: 4152

The word [hygiene] is defined as the "science of the establishment and maintenance of health"(Merriam-Webster). Another definition is "conditions or practices conducive to maintaining health and preventing disease, especially through cleanliness".

In Greek mythology Hygeiea [Υγιείας] is the goddess of health, one of the daughters of Aesculapius, who is himself the god of Medicine. Aesculapius was represented as a figure leaning on a staff around which a serpent is coiled.

The Greek word [υγιής], a derivative from the name of the goddess Hygieia means "healthy", "sound" or "strong", and became the root for our modern word [hygiene]. Because of its mythological origin, there must be something to the saying "cleanliness is next to godliness".

The image of the statue of Hygieia acompanying this article is known as the "Hope Hygieia" and is on display at the J. Paul Getty Museum.  The statue shows Aesculapius' snake, a symbol of renovation. This statue was discovered in 1797 at the port of Ostia in Rome. The statue was restored, de-restored, and re-restored. For more information of this statue's history CLICK HERE.
