A Moment in History

William S. Halsted, MD

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, also known as  "Halsted's Rules of Surgery", 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.

Medical Terminology Daily

One of my interests is the origin and evolution (etymology) of medical terminology. Because of this, in October 2012 we started on the Clinical Anatomy Associates website a blog called "Medical Terminology Daily". Originally, I thought we could do one article per day… oh how wrong I was!!, but we kept the name and, since then, over one thousand articles have been published.

The first article in the blog was the medical term “Bariatric”. Today we will analyze this term again and the medical derivations that arise from one of these root terms.

The term "bariatric" is a compound word with two Greek roots: βάρος, meaning "weight" or "pressure", and γιατρός meaning "doctor, physician, or healer". The adjectival suffix [-ic] that closes the word means "pertaining to". The term bariatric then means "pertaining to weight-related medicine".

Let’s look at some of the many uses of the root “iatr-“in medical terminology. Remember, you only add an “o” as in “iatr-o” (the combining form of a word) when you are combining a root term with another root or a suffix

TERM

ETYMOLOGY
(in addition to iatr-)

DEFINITION

Iatrogenic 
synonym (nosocomial)

Greek: γέννα (génna) meaning birth, create, produce

Denoting an illness or adverse condition caused by medical treatment or physician intervention

Pediatrics

Greek: παιδί (paidí) meaning child

The branch of medicine dealing with the health and medical care of infants, children, and adolescents

Psychiatry

Podiatry

Greek: πόδι (pódi) meaning foot

There are variations of the suffixes added to the root term iatr-. Examples of these are:

-iatry - denoting the field of practice, such as pediatry, podiatry, psychiatry. etc.

-iatrist - the person practicing that particular field, such as psychiatrist, geriatrist, etc.

-iatrician - another way of denoting the field of practice, such as pediatrician.
