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.

The deltoid or deltoideus (Latin) is a large, thick, triangular muscle, which covers the glenohumeral joint anteriorly, superiorly, and posteriorly. It can be described as having three components or segments, anterior, middle, and posterior. The anterior portion originates from the lateral third of the clavicle, on the clavicle’s superior border. The middle portion originates from the lateral border of the scapula’s acromion, and the posterior portion originates from the spine of the scapula. All three portions insert laterally by means of a thick tendon on the deltoid tuberosity of the humerus. At its insertion the muscle gives off an thick connective tissue expansion to the deep fascia of the arm.
The three portions of the deltoid muscle are usually well defined. As an anatomical variation, the clavicular or the acromial portion of the muscle may be absent.
This muscle is innervated by the axillary nerve (C5, C6), a branch of the brachial plexus, and supplied by the posterior circumflex humeral artery and the deltoid branch of the thoracoacromial artery.
The word deltoid is derivates from the Greek word [δελτοειδής] which is itself formed by the terms [δέλτα] (délta), referring to the triangular shape of the letter delta (uppercase Δ, lowercase δ) and [-οειδής] (-oeidís), a the Greek suffix meaning “similar to”. Delt-oid then would mean “similar to a Δ (delta)".
The deltoid is one of the 17 muscles that attach to the scapula.

Holly leaf sign.
Click on the image for a larger depiction
The Holly is a tree/shrub of the genus Ilex , with perhaps the most well know being Ilex aquifolium. The plant has shiny prickly evergreen leaves and bright red berries. Cut branches of Holly are widely used as a traditionally Christmas decoration especially in wreaths and Christmas cards as illustrations. “The Holly and the Ivy” is a popular traditional English Christmas carol.
The [Holly leaf sign] refers to the appearance of calcified pleural plaques seen on chest radiographs. Pleural plaques are common in patients who have been exposed to asbestos, are asymptomatic and are most useful as a marker of asbestos exposure or asbestosis. They can be identified in 3-14% of dockyard workers and in 58% in insulation workers.
They are themselves not malignant, but patients with this plaques have a greater risk of mesothelioma and bronchogenic cancer than the general population and patients with exposed to asbestos but not pleural plaques.
The plaques arise in the parietal pleura and have predilection for the diaphragmatic dome and the undersurface of the lower posterolateral ribs. Rarely involve the visceral pleura but occasionally they are found in the fissures of the lungs.
On plain radiographic plaques appear as a geographic, usually calcified, opacities with irregular but well-defined edges. The irregular thickened nodular edges of the pleural plaques are likened to appearance of a Holly leaf, which has sharp spines along its margin.

Anterior view of a section of the prostate gland. The blue
dotted line shows the edges of the prostatic urethra
[UPDATED] The [prostatic utricle], also known as "utriculus prostaticus" or "utriculus" is a small 6 mm small dead-end channel found in the male prostatic urethra.
The word [utriculus] is Latin and means "little sac"..
What is interesting about this structure is that it is the embryological remnant in the male of the Müllerian ducts that form the vagina and the uterus in the female. In fact, in some texts the prostatic utricle is referred to as "uterus masculinus". Some researchers differ and point to the fact that this structure may not be a Müllerian duct derivate.
The prostatic utricle is found inside the prostate, forming part of the posterior wall of the prostatic urethra. It is in the upper part of a small mound which is part of the prostatic crest. This mound is called the [colliculus seminalis] or [verumontanum], which is Latin and translates as the "mountain or mound of truth". On the verumontanum are the two slit-like openings of the ejaculatory ducts. Lateral to the verumontanum are the prostatic sinuses, depressions where the prostatic ducts are found.

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.

Jane Todd Crawford - Daguerrotype
When writing the article “The Ephraim McDowell House and Museum” I realized that there are so many patients that by volunteering to a novel or sometimes experimental procedure or donating their bodies have been the catalyst of the advancement of medical science, surgery, and anatomy. Benigno says it so clearly in his paper explaining the physician/patient relation of McDowell and his patient: “Because of his innovative genius and finally honed surgical skills, Ephraim McDowell gave Jane Todd Crawford her life, and she, in return, gave him immortality”.
Few patients have influenced local history more than Jane Todd Crawford. In Kentucky there is a road named after her, a hospital bears her name in Greenville, KY, and there is even a formal "Jane Todd Crawford Day" on December 13!
By contrast, there are so many unknown patients whose names history has forgotten, and yet the fame of the physician continues through time in eponymic hospitals, educational institutions, named surgical procedures or maneuvers, surgical instruments, etc.
Some of the names and stories have survived, but many have not. In some cases, we know the name, but little else.
Dr. Henry Heimlich used his “Heimlich maneuver” for the first time to save his neighbor Patty Ris, in 2016, forty-two years after publishing it in 1974. The maneuver itself was used that same year (1974) to save the first person, Irene Bogachus, who was choking at a restaurant. Hundreds of thousands of people have been saved from death from choking by the proper use of this maneuver.
Dr. Christiaan Barnard, performed the first successful heart transplant on December 3, 1967. We know the name of the donor, 25 year-old Denise Darvall, and the recipient Lewis Washkansky.
Dr. Antoine Dubois and Dr. Dominique-Jean Larrey in France performed the first mastectomy on September 30, 1811. This was decades before the advent of anesthesia or aseptic technique. The patients was Fanny Burney, a famous novelist.
Dr. Edward Jenner developed the smallpox vaccine after working with a milkmaid, Sarah Nelmes. Jenner’s work saved the Americas from the smallpox epidemic through the work of Don Antonio de Gimbernat y Arbós and Don Francisco Javier de Balmis i Berenguer and his “Balmis Expedition”
The examples can continue, but who was the patient on the first Billroth procedure, who was the patient in the first Scopinaro procedure? Who was the patient on whom Dr. Eric Muhe performed the first laparoscopic cholecystectomy? Many are unknown yet they helped pave the way of the future.
The same can be said for the world of human anatomy. Today we honor the donors who will their bodies so that future physicians can study the intricacy of the human body, but we never know their names or their stories. Many a time I have stood at the side of a body while medical students dissect and study and wondered about their identities, the life they had, and what led them to give us their bodies as a wonderful gift to science and medicine.
There was a time (long ago) when the dissection of a human body was punished by the Church, or the times when the scarcity of bodies was such that some started to rob graves, or when the punishment for a crime was “death and a public anatomy”.
Some of these people we know, most of them we do not. Some have given their body willingly, others have not.
Joseph Paul Jernigan, a murderer, who after given the death penalty, donated his body to a now world-renown endeavor, the Visible Human Project.
The oldest known anatomical preparation is a skeleton mounted in Basel (Belgium) by Andreas Vesalius in 1543. The skeleton belongs to Jacob Karrer von Geweiler, a bigamist and attempted murderer who was beheaded for his crimes.
It is sad that we know the names of these criminals, and in some cases not that of their victims.
We do not know the names of many who, during the Nazi regime in WWII, were taken from concentration camps for medical experiments and as we understand, possibly murdered and dissected to illustrate now infamous anatomical atlases. Research is being done to discover their identities.
Times have changed and body donation has become accepted and praised by society. I am always touched by the words of Morgagni above the entrance to the dissection rooms at the University of Cincinnati: “hic locus est ubi mors gaudet succurrere vitae” meaning “in this place death rejoices helping the living”. The University of Cincinnati has an Annual Memorial Ceremony to honor the body donors and their families. A video of the ceremony can be watched here.
I cannot but end this article with the words that are found in the left side column of this blog and will always be there:
“Clinical Anatomy Associates, Inc., and the contributors of "Medical Terminology Daily" wish to thank all individuals who donate their bodies and tissues for the advancement of education and research”.

Susan C. Potter
Image capture from a video
The title of this article is a reference to another article in this blog: “The unknown patient / donor” which honors all those who have anonymously donated their bodies to further the anatomical training of many in the medical field. They trusted that those who would use their bodies would do so ethically and with respect, but they did not know exactly how they were to be used or what was going to be done with their bodies.
Susan Potter was the exact opposite. She knew that her body was going to be coated with polyvinyl alcohol, frozen, cut into four pieces with a huge handsaw, and then it would be ground or milled into 27,000 slices of 63 microns each, which were to be photographed in exquisite detail.
She offered her body to science and spoke with Dr. Vic Spitzer, who had directed the Visible Human Project, the first digital cadaver in 1994. She agreed to the donation, but only after she had toured the facilities and only after she clearly understood what was going to her body and why.
The why is the most interesting part of her story. Susan had a very interesting medical history, including spinal surgery , double mastectomy, and a hip replacement. Normally her body would have been rejected, but doctors see this type of patients in their practices. Patients who are old, frail, with prior surgeries and a multitude of problems. This is why she was chosen
If images are needed, usually cadavers are scanned and imaged postmortem, but in her case, Susan underwent many imaging studies while she was alive. She was interviewed and filmed countless times so that her videos would be added to the digital cadaver that was going to be made of her, becoming de facto, a digital patient.
Susan donated her body in the year 2000 died of pneumonia in 2015. During those 15 years she became a friend of Dr. Spitzer, gave talks to medical students, and collaborated with this project.
National Geographic followed Susan for these 15 years and documented her life and death. You can read her story here or watch the video in this article. The development of the software continues. I am sure we will hear more from Susan Potter's contributions long after her death.
NOTE: My thanks to our contributor Pascalle Pollier for bringing Susan Potter to my attention. Dr. Miranda
