A Moment in History

William S. Halsted, MD
(1852 – 1922)

American anatomist, teacher, and surgeon, William Stewart Halsted was born in New York City, USA to a wealthy family of English origin. His father was involved in charitable work and Governor and trustee to a city hospital. Not a brilliant student initially, Halsted took an undergraduate in Liberal Arts in Yale, CT., after which he entered the Medical College of Physicians at the Columbia College, where he excelled.

As a second-year medical student Halsted applied and obtained a position in surgery at a local hospital. In here he learned about Lister’s antiseptic technique and became an adamant proponent of it to reduce infection. In 1877 Halsted obtained his MD. After a short time as House Physician at the New York Hospital, Halsted traveled to Europe to further his education studying for two years at the Universities of Vienna, Leipzig, and W?rzburg.

Besides being at the forefront of surgical and antiseptic techniques (introducing the use of rubber gloves in surgery), Halsted was extremely concerned with the way medical students were taught in the US. He pioneered bedside clinical round discussions with the medical students after two years of basic sciences studies. Halsted developed the idea of a patient chart; he also developed the residency program for medical students in use today.

Halsted is probably the most influential researcher and surgeon at the turn of the century. He dedicated time to the study of intestinal anastomoses and the use of silk as a suture material. His experimental work in 1887 proved that the inclusion of the submucosa layer in an anastomosis was mandatory, as well that a single layered anastomosis was enough to attain closure. Perhaps Halsted’s most important contribution was the application and use of the scientific method to surgical questions. Halsted’s principles set the standards used today in surgical suturing and surgical stapling.

He also pioneered the development and surgical techniques for radical mastectomy as a treatment for breast cancer.

As a side effect of this studied in anesthesia and the use of cocaine for anesthesia, Halsted became addicted to this substance, a problem that followed him through the years. Without impairing his capacity as a researcher and a surgeon, Halsted eventually recovered. He died in Baltimore in 1922 as a complication to surgery.

Arantius

Giulio Cesare Aranzio (1530 -1589) Italian surgeon and anatomist. Born in Bologna, Giulio Cesare Aranzio is better known by the Latinized version of his name Julius Caesar Arantius. His Italian last name is sometimes spelled Aranzi.

Born in a poor family, Aranzio began his medical studies under the tutelage of his uncle, Bartolommeo Maggi (1477 – 1552), studied medicine at the University of Bologna where he graduated MD in 1556. The same year he became a Professor of Anatomy and Surgery at the in 1556. Arantius was the first lecturer at the University of Bologna to hold a separate professorship of anatomy. Before him, the University would allow any surgeon to perform dissection and lectures.

Arantius had several publications that include:

• Observationes Anatomicas (Anatomical Observations)
• De Humano Foetu Opusculum (On the Human Fetus)
• De Tumoribus Secundum Locos Affectos (Tumors according to the affected places)
• Hippocratis librum de vulneribus capitis commentarius brevis (Short commentary on Hippocrates’ book on head wounds)

Arantius was the first to describe the foramen ovale (fossa ovalis) and the ductus arteriosus, discoveries that were later erroneously ascribed to Leonardo Bottalus (Botal). He also described the nodules in the leaflets of the aortic valve that today bear his name (nodules of Arantius) which he described as being “cartilaginous” in nature. This is not as farfetched as it seems as these nodules can become hypertrophic and harden with age. Arantius was also the first to describe the hippocampus, a formation on the brain associated with the limbic system, mood disorders, and depression.

Arantius was a consummate anatomist and a great surgeon. Apparently he treated nasal polyps, performed nasal reconstructions and a number of surgeries ahead of his time. One of his great anatomical observations was that the blood in the heart did not pass through “invisible pores” in the interventricular septum, but rather exits the heart through the pulmonary trunk, setting the stage for the discovery of circulation by William Harvey (1578 – 1609)

We have not been able to find a portrait of Arantius and the only reference is a a bust with the name “Aranzio” located at the Biblioteca comunale dell'Archiginnasio in Bologna, Italy. The bust is found in the anatomical amphitheater, built in 1637. Unfortunately, the theater was severly damaged in January 29, 1944 during WWII. It has been meticulously restored over the years. Here is an article (in Italian) on the amphitheater.
