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

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.

Musculi levator labii superioris alaeque nasi

The [musculi levator labii superioris alaeque nasi] is one of the superficial muscles of expression found in the face. It is a small bilateral muscle found at the angle of the nose and its function is to elevate the superior lip and the side ("wing") of the nose, slightly opening or "flaring" it. When both of these muscles are activated the facial expression attained is called a "snarl".

My friend Dr. Elizabeth Murray calls it "a small muscle with the longest name in human anatomy". Fact is, I think she is right!

Cancer

The term [cancer] is Latin and means "crab". The word was first used by Galen of Pergamon (129AD - 200AD) who used it to describe the crab-like appearence of the veins of a cancerous tumor, probably a breast cancer. Galen said "... as a crab's feet extend from every part of its body, so in this disease are the veins distended, forming a similar figure". The term cancer is also used in other applications, such as astronomy (Tropic of Cancer) and astrology, as in the zodiacal sign of Cancer. 

The Latin term [cancer] was probably pronounced "kanker" and this may be the origin of the term [canker] to refer to ulcerations around the mouth or angles of the mouth, canker sores. This is also probably the origin of the term [chancre] used for some dried-out sore wounds. 

Greek terms merged into the New Latin, so the Greek terms derived from [karkinos] also made it into modern medical terminology.

The word [cancer] is used today to denote a malignant tumor. There are variations of the term using the root term [-carcin-] as in [carcinoma].

Obstetrics

The term [obstetrics] arises from the Latin word [obstare] which means "to stand close to" or "to stand in front of". Since a midwife "stands" in front of the patient for child delivery, the word was used in its feminine singular form [obstetrix]. The Latin plural is [obstetrices]; The evolution of the term into modern "obstetrics" is quite clear.

Through the ages the term used for someone who helps deliver a child has changed. Andreas Vesalius used the term [obstetrices nutrices] meaning "nurse nmidwife". The term "midwife" was used for a long time, being replaced today for the word "obstetrics" and "obstetrician".

A man-midwife and a 'modesty blanket' c.1681
Although all female reproductive system care was originally the domain of midwives, through time two distinct specialties have evolved. Gynecology refers to the medical specialty that studies and treats the female reproductive system. Obstetrics, deals with the care of the pregnant patient and delivery of the fetus. Male-widwives in Europe were allowed access to the patient only with the use of a "modesty blanket". This is plate XV from the 1681 book "Korte en Bondige Van Der Voortteeling en Kinderbaren" by Samuel Janson.

As an interesting side note in history, the first male physician to attempt to work as a man-midwife was Dr. Wertt from Hamburg. Dr Wertt decided to disguise himself as a woman to attend patients. When he was discovered, the punishment was "swift and salutary": He was burned at the stake.

Avicenna


This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.To search all the articles in this series, click here.
Avicenna (980 AD – 1037 AD) Persian physician, philosopher, mathematician, naturalist, geologist, musical theorist, astronomer and poet. Ab? Al? al-Hysayn ibn-‘Abd-All?h ibn-S?na, also known as “ibn-S?na“ and as “Avicenna” was born in Afshaneh, near the city of Bokhara (in old Persia, what today is Iran) in 980AD.

Intellectually gifted, Avicenna studied philosophy and the Islam religion, with early studies in medicine. By age 18 he was already a famous physician. With access to the royal library Avicenna continued his studies and traveled through what today is Iran. Avicenna had government positions, becoming prime minister. Jailed for political reasons Avicenna wrote a large number of his medical, philosophical, and astronomical publications while in jail.

Of over 450 total medical books attributed to Avicenna, his most famous publication was the “al-Qanun-fi-al-Tibb” or the “Canon of Medicine”, consisting of five books on principles of medicine, diseases, drugs, and compound medicines. The Canon was translated into Latin and later into other languages, remaining an important book for at least until the 16th century.

Avicenna
He used the term “vermis” and spoke of the “tailed nucleus”, known to us as the “caudate nucleus”. Avicenna died in 1037AD at 57 years of age. He was buried in the city of Hamadh?n, where his tomb still exists. Avicenna has been called the “prince of physicians”.

-salping-

The root term [-salping-] arises from the Greek [σάλπιγγα] or [salpinx],  meaning "trumpet" or "bugle".  Because of their trumpet shape, there are two anatomical structures where this term applies, one is the uterine or Fallopian tube, and the other is the auditory or Eustachian tube.

This root term is used in medical terms such as:

Salpingitis: An inflammation or infection of the Fallopian (uterine) tube

Salpingectomy: Removal of one or both Fallopian tubes

Salpingopharyngeus: A muscle that extends between the Eustachian (auditory) tube and the pharynx

View of the adnexa
 
Salpingooophorectomy: This combined root term adds the root [-oophor-] meaning ovary. The suffix [-ectomy] means "removal". The removal of the uterine tubes and the ovaries. This operation can be unilateral or bilateral.

Because of the rules of combination for root terms, the commonly used hyphenated [salpingo-oophorectomy] form of this word is not correct and should not be used.
