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.

Dr. Salomón Hakim (1922 - 2011). Dr. Hakim was born in the city of Barranquilla, Colombia. He started medical school in 1944 and elected neurosurgery as his specialty. He had special interest in electricity and physics, which he used extensively in his research.

In 1957 Dr. Hakim was exposed to a strange case of a young man with what was known then as "symptomatic occult hydrocephalus". Until that time the accepted knowledge was that hydrocephalus was due to an increase in intracranial pressure of different etiology. The problem was that the young man had normal pressure, yet had a hydrocephalus and enlarged ventricles. Dr. Hakim applied his knowledge of physics and laid the conceptual basis for what became known as "Normal Pressure Hydrocephalus" a condition until then unrecognized and that is found in aging patients with dementia, Alzheimer's, and other pathologies.

Working at home, Dr. Hakim developed a pressure-regulating shunt to drain the excess cerebrospinal fluid (CSF) from the ventricular system of the brain. These valves were later produced by medical industry. His son Carlos has continued his legacy and now the Hakim programmable valve is one of the best CSF shunt systems in the world.

I had the pleasure of meeting Dr. Hakim in 1993 in Santiago, Chile, and again later in the US, as he presented his valve system to a group of neurosurgeons. This short article does not do justice to the physician, researcher, and family man. I encourage you to read more in the following links. Dr. Miranda
