A Moment in History

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".

Nabothian cyst

Published: Tuesday, April 14, 2015 07:00 | Written by: Efrain A. Miranda, Ph.D. | Hits: 10613

A cyst is a sac-like structure filled with fluid. One of the many types of cysts that can be present in the human body is a Nabothian cyst.

Nabothian cysts are found on the uterine cervix, and are caused by the clogging of the cervical glands, also referred to as the Nabothian glands. These small cysts are usually found in two types of presentations. The first are serous filled cysts, and are seen as clear fluid-filled sacs on the surface of the cervix. In the accompanying image, these are depicted with a yellow circle.

The second type of Nabothian cysts are sacs filled with a yellowish, more dense and mucous-like fluid on the surface of the cervix. In the accompanying image, there is only one of these cysts and is depicted with a red circle.

Uterine cervix with three Nabothian cysts

The presence of Nabothian cysts is quite normal, they are not dangerous and are not cancerous. When present and when large, they may impede a gynecological exam and obscure the cervical os, the entrance to the uterus through the cervical canal. In the image the cervical os is indicated by a blue arrow. A gynecologist may need to open and drain these cysts prior to performing a Pap smear (named after Dr. George Papanicolau).

Nabothian cysts are named after Dr. Martin Naboth (1675 - 1721), a German physician and anatomist. His main publication in 1707 was “De Sterilitate Mulierum” (On Sterility in Women). In this book he refers to small pearl-like transparent structures found in the uterine cervix. Believing that he had discovered the way women store eggs, he called these “ovarium novum” (new ovaries). His discovery was accepted by many and these structures came to be known as “Ovula Nabothii“. Today we know this is not true, but his name remains attached eponymically to these structures.
