Georg Eduard Von Rindfleisch
(1836 – 1908)
German pathologist and histologist of Bavarian nobility ancestry. Rindfleisch studied medicine in Würzburg, Berlin, and Heidelberg, earning his MD in 1859 with the thesis “De Vasorum Genesi” (on the generation of vessels) under the tutelage of Rudolf Virchow (1821 - 1902). He then continued as a assistant to Virchow in a newly founded institute in Berlin. He then moved to Breslau in 1861 as an assistant to Rudolf Heidenhain (1834–1897), becoming a professor of pathological anatomy. In 1865 he became full professor in Bonn and in 1874 in Würzburg, where a new pathological institute was built according to his design (completed in 1878), where he worked until his retirement in 1906.
He was the first to describe the inflammatory background of multiple sclerosis in 1863, when he noted that demyelinated lesions have in their center small vessels that are surrounded by a leukocyte inflammatory infiltrate.
After extensive investigations, he suspected an infectious origin of tuberculosis - even before Robert Koch's detection of the tuberculosis bacillus in 1892. Rindfleisch 's special achievement is the description of the morphologically conspicuous macrophages in typhoid inflammation. His distinction between myocardial infarction and myocarditis in 1890 is also of lasting importance.
Associated eponyms
"Rindfleisch's folds": Usually a single semilunar fold of the serous surface of the pericardium around the origin of the aorta. Also known as the plica semilunaris aortæ.
"Rindfleisch's cells": Historical (and obsolete) name for eosinophilic leukocytes.
Personal note: G. Rindfleisch’s book “Traité D' Histologie Pathologique” 2nd edition (1873) is now part of my library. This book was translated from German to French by Dr. Frédéric Gross (1844-1927) , Associate Professor of the Medicine Faculty in Nancy, France. The book is dedicated to Dr. Theodore Billroth (1829-1894), an important surgeon whose pioneering work on subtotal gastrectomies paved the way for today’s robotic bariatric surgery. Dr. Miranda.

This suffix [-(o)centesis] arises from the Greek [kentesis], meaning "to tap" or "to perforate", referring to a needle or trocar. In practical terms, this suffix means "needle aspiration of". Examples of its use are:
- Pericardiocenteses: Needle aspiration of the pericardium
- Thoracocentesis: Needle aspiration of the thorax. The use of the term "thoracentesis" is wrong!
- Amniocentesis: Needle aspiration of the amniotic sac
- Arthrocentesis: Needle aspiration of a joint

Ephraim McDowell
Ephraim McDowell (1771- 1830). American surgeon, Ephraim McDowell was born in 1771 in the Augusta County of Virginia. His family moved to the “frontier”, which at that time was Kentucky, where his father was a judge. McDowell studied in Kentucky and returned to Virginia to serve as an apprentice to Dr. Alexander Humphreys. Following Dr. Humphrey’s advice McDowell went to Edinburgh to finish his formal medical training, which he did not finish, taking chemistry, anatomy, and then a private medical course with Dr. John Bell.
Returning to America, he settled in the Ohio River Valley, and had a successful practice as a frontier surgeon in the city of Danville, Kentucky. This was before the advent of anesthesia and antisepsis.
On Christmas Day 1809, Dr. McDowell performed the first recorded ovariotomy to drain a massive ovarian cyst from Mrs. Mary Jane Crawford, who had to ride a horse for sixty miles to get to Dr. McDowell’s office where he performed the ovariotomy without anesthesia. Mrs. Crawford had been diagnosed as “pregnant” by two other physicians. Dr. McDowell’s hand-written report states that he performed a nine-inch abdominal incision, the operation lasted about twenty five minutes, and they removed “fifteen pounds of a dirty gelatinous substance” and “extracted the sac, which weighed seven and a half pounds”.
Mrs. Crawford survived the operation, was ambulatory in five days, and lived for 33 additional years, until she was 78 years old. Research has been made as to the reason for the survival at a time when the norm for an operation that penetrated the peritoneal cavity was death. Othersen (2004) states that his research indicated that Dr. McDowell was “meticulous, neat and scrupulously clean”.
Because of the times, and because Dr. McDowell was not into writing, the achievement was not known for many years, until 1817. Dr. McDowell later performed a lithotomy on James Polk, who would eventually become president of the United States. In 1825, his achievements were recognized and he received an honorary MD degree by the University of Maryland.
Dr. McDowell’s house in Danville, KY is today a museum, and his name is remembered by the “Ephraim McDowell Health System” a group of integrated healthcare based in the same city. For more information on Mary Jane Crawford, click here.

Anteroinferior view of the liver and stomach
The [lesser omentum] is a double-layered peritoneal membrane found between the stomach and the first portion of the duodenum and the liver.
Between the two layers of the lesser omentum there is a small amount of fat, the coronary vein, the arteries of the lesser curvature vascular arcade, the gastroduodenal artery, and the structures of the portal triad: Portal vein, common bile duct, and proper hepatic artery.
The lesser omentum is divided into two subcomponents:
- The gastrohepatic ligament, the larger component, found between the lesser curvature and the liver. It includes the pylorus.
- The gastroduodenal ligament, the smaller component, found between the first portion of the duodenum (superior portion, duodenal ampulla) and the liver. The common bile duct is found between the layers of the omentum.

The word [celiac] is the American version of the more internationally used term [cæliac]. It derives from the New Latin word [c?liacus] which means "pertaining to the bowels". This term in turn arises from an older Greek term [koilus] which means "hollow", "cave", or "cavity". By extension the words celiac or cæliac have come to mean "pertaining to the abdominal cavity".
In embryology, the term [celomic cavity] (a redundancy) is used to denote the combined abdominal and thoracic cavities in the embryo before the respiratory diaphragm separates these two into two separate bodily cavities.
The term [celiac] is used in other words such as:
- Celiac trunk: one of the unpaired branches of the abdominal aorta
- Celiac disease: an abdominal pathology characterized by distention and retention
- Celiac plexus: a plexus of autonomic nerves found around the celiac trunk.

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 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.
