Anatomical variations (3)

Medical Terminology Daily (MTD) is a blog sponsored by Clinical Anatomy Associates, Inc. as a service to the medical community. We post anatomical, medical or surgical terms, their meaning and usage, as well as biographical notes on anatomists, surgeons, and researchers through the ages.

A Moment in History

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.

"Nothing in the human body is colored, or labeled"

"The Chirurgeon must knowe the Anatomie". Thus states Thomas Vicary (1460 -1561) on the knowledge of Anatomy. He continues: "...for all authors write against those surgeons who work in a man's body not knowing the Anatomie"¹. There is no doubt that knowledge must include the awareness of the possibility of anatomical variations. Some anatomical variations, like the "Corona Mortis" can be critical, and in some surgical cases, be the cause for exsanguination!

It is interesting that several medical schools are reducing the total number of hours working on, or moving away from cadaver disection in first year medical school and using computer simulations instead. No computer simulation will give the medical student the detail, variations, and feel of the tissues as actual hands-on experience. I am sure no one wants a surgeon whose first view of the internal aspect of a human body is a living patient...on the surgical table.

It is a fact that "Nothing in the human body is really colored... or labeled" or as someone else said "nothing looks exactly like the anatomy book", unless it is photography, and then each photo is taken after hours of laboring to "Netterize" the organ or area that one is trying to detail. Nothing gives the future professional the exact idea of what to expect in the future patient than the hours and hours of laborious work in the anatomy laboratory.

The same is true with anatomical variations, one "standard" digital cadaver,even with built-in anatomical variations does not give the student the sense of awe and discovery when an anatomical variation is found, interpreted, and analyzed with a group of peers, contributing to the learning process and the formation of future health care professionals.When questioning what is normal or abnormal, Dr. Elizabeth Murray says it most elegantly: "The cadaver is always right"
