The practice of medicine changed in the face of rapid advances in science, as well as new approaches by physicians. Hospital doctors began much more systematic analysis of patients' symptoms in diagnosis. Among the more powerful new techniques were anaesthesia, and the development of both antiseptic and aseptic operating theatres. Effective cures were developed for certain endemic infectious diseases. However the decline in many of the most lethal diseases was due more to improvements in public health and nutrition than to advances in medicine.
Herophilus of Chalcedon, working at the medical school of Alexandria placed intelligence in the brain, and connected the nervous system to motion and sensation. Herophilus also distinguished between veins and arteries, noting that the latter pulse while the former do not. He and his contemporary, Erasistratus of Chios, researched the role of veins and nerves, mapping their courses across the body. Erasistratus connected the increased complexity of the surface of the human brain compared to other animals to its superior intelligence. He sometimes employed experiments to further his research, at one time repeatedly weighing a caged bird, and noting its weight loss between feeding times. In Erasistratus' physiology, air enters the body, is then drawn by the lungs into the heart, where it is transformed into vital spirit, and is then pumped by the arteries throughout the body. Some of this vital spirit reaches the brain, where it is transformed into animal spirit, which is then distributed by the nerves.
Last time we featured her, the Evolution of Medicine community showed support and interest that made a real difference. Thank you! We bring her back this week to share an update about Organize. She and her team were recently at the White House to speak about their project with some important influencers from the industry. She shares with us what she learned and what they were able to accomplish.
The Department of the History of Medicine at Johns Hopkins is proud to introduce new online CME modules that provide a historical perspective on issues of relevance to clinical practice today. Our first module, which launched in January 2018, explores the social, political, and economic forces that continue to shape the dynamic boundaries of the medical profession. Medical professionalism is...
“Rescaling Colonial Life From the Indigenous to the Alien: The Late 20th Century Search for Human Biological Futures,“ follows the reach of colonial practices of natural history through genomics and into outer space. The article centers around biochemist and medical anthropologist Baruch Blumberg, who began his career collecting samples from colonial subjects in Surinam and ended it as head of the NASA program in Astrobiology. Joanna Radin’s history traces entwinements of colonial natural history, space exploration, and inductive methods in postwar biological science.
In 1478 a book by the Roman doctor Celsus was printed. (The printing press made all books including medical ones much cheaper). The book by Celsus quickly became a standard textbook. However in the early 16th century a man named Theophrastus von Hohenheim (1493-1541) called himself Paracelsus (meaning beyond or surpassing Celsus). He denounced all medical teaching not based on experiment and experience. However traditional ideas on medicine held sway for long afterwards.
Another great surgeon was Ambroise Pare. In the 16th century surgeons put oil on wounds. However in 1536 during the siege of Turin Pare ran out of oil. He made a mixture of egg whites, rose oil and turpentine and discovered it worked better than oil. Pare also designed artificial limbs. In 1513 a man named Eucharius Roslin published a book about childbirth called Rosengarten. In 1540 an English translation called The Birth of Mankind was published. It became a standard text although midwives were women.
This has been a huge acceleration for our organization. James published his book The Evolution of Medicine. We launched the Evolution of Medicine Practice Accelerator and as always, we've had our monthly the Functional Forum episodes. We've recently introduced the "Future of Functional in 5" which allows our community of practitioners to share their stories and gifts with the whole community. Our Functional Forum meetups continue to facilitate collaboration and community building for practitioners on a local level. James and Gabe also discuss what's new for the Evolution of Medicine and share details about a course on building a Functional Membership practice, as well as bringing new doctors into our community consistently.
This week on the Evolution of Medicine, we continue our popular “Success Leaves Clues” series. We feature Dr. Bill Hemmer, a chiropractor from central Illinois who is bringing functional medicine to his small hometown with a population of only 4500. It was an incredible half an hour for any health professional who is in the business of trying to transform the health of their community.
The Roman contribution to the history of medicine is often overlooked, with only Galen, of Greek origin, believed to be notable of mention. However, this does the Romans a great disservice and they put their excellent engineering skills to use in preventative medicine. The Romans understood the role of dirt and poor hygiene in spreading disease and created aqueducts to ensure that the inhabitants of a city received clean water. The Roman engineers also installed elaborate sewage systems to carry away waste. This is something that Europeans did not fully understand until the 19th Century; before this period, sewage was still discharged close to drinking water.
Due to the hot and dry climate in Egypt, ancient papyri have survived intact, allowing historians to study the sophisticated techniques employed by Ancient Egyptian physicians. Whilst couched in magic and ritual, the Egyptians possessed a great deal of knowledge of healing herbs and repairing physical injuries, amongst the normal population and the workers responsible for building the great monuments of that nation.
Japanese physicians immediately recognized the values of X-Rays. They were able to purchase the equipment locally from the Shimadzu Company, which developed, manufactured, marketed, and distributed X-Ray machines after 1900. Japan not only adopted German methods of public health in the home islands, but implemented them in its colonies, especially Korea and Taiwan, and after 1931 in Manchuria. A heavy investment in sanitation resulted in a dramatic increase of life expectancy.
Anatomy: A brief introduction Anatomy identifies and describes the structure of living things, and is essential to the practice of health and medicine. It can involve the study of larger biological structures, called gross anatomy, or of cells and tissues, known as microscopic anatomy or histology. Learn more about the importance of anatomy here.

The Egyptians did have some knowledge of anatomy from making mummies. To embalm a dead body they first removed the principal organs, which would otherwise rot. However Egyptian surgery was limited to such things as treating wounds and broken bones and dealing with boils and abscesses. The Egyptians used clamps, sutures and cauterization. They had surgical instruments like probes, saws, forceps, scalpels and scissors. They also knew that honey helped to prevent wounds becoming infected. (It is a natural antiseptic). They also dressed wounds with willow bark, which has the same effect. The Egyptians were clean people. They washed daily and changed their clothes regularly, which must have helped their health.
2016 The success of an first-time experimental surgery will determine future availability for U.S. cancer patients and veterans with injuries to the pelvic region. On May 8, 2016, a man named Thomas Manning is the first man to receive a penis transplant at the Massachusetts General Hospital. Manning's recovery from the surgery is going well; John Hopkins University School of Medicine is also hoping to start providing the surgery soon.
1656 Experimenting on dogs, English architect Sir Christopher Wren is the first to administer medications intravenously by means of an animal bladder attached to a sharpened quill. Wren also experiments with canine blood transfusions (although safe human blood transfusions only became feasible after Karl Landsteiner develops the ABO blood-typing system in 1900).
China also developed a large body of traditional medicine. Much of the philosophy of traditional Chinese medicine derived from empirical observations of disease and illness by Taoist physicians and reflects the classical Chinese belief that individual human experiences express causative principles effective in the environment at all scales. These causative principles, whether material, essential, or mystical, correlate as the expression of the natural order of the universe.
Cardiology used to be the study of the heart - but in the last couple decade it's been more about the study of cardiac procedures. Not all of these procedures have long term benefits and most just treat the symptoms and do not prevent future events. Dr. Masley looks at this from a preventative and lifestyle medicine perspective and works to educate both patients and practitioners on what they can do to avoid seeing a cardiologist altogether.
Small Intestinal Bacteria Overgrowth - it's become a buzzword in medicine the past few years and Chris has been on the cutting edge of treating it. We'll be discussing the standard diagnosis, why it's problematic, and what we can do about it. There podcast has tons of value for practitioners who are on the front lines of dealing with a range of digestive and other related issues.
The term ‘technology’ is based on the ancient Greek techné (‘art’, ‘skill’, ‘craft’) (logos means ‘study’). Greek medical texts describe medicine as a techné, suggesting that it was a skill to know why and how to treat a condition. For us, ‘medicine’ is “the science or practice of the diagnosis, treatment, and prevention of disease” (Oxford English Dictionary).
Some 200 years later another doctor, Peseshet, was immortalised on a monument in the tomb of her son, Akhet-Hetep (aka Akhethetep), a high priest. Peseshet held the title ‘overseer of female physicians’, suggesting that women doctors weren’t just occasional one-offs. Peseshet herself was either one of them or a director responsible for their organisation and training.
Many contemporary humans engage in little physical exercise compared to the physically active lifestyles of ancestral hunter-gatherers. Prolonged periods of inactivity may have only occurred in early humans following illness or injury, so a modern sedentary lifestyle may continuously cue the body to trigger life preserving metabolic and stress-related responses such as inflammation, and some theorize that this causes chronic diseases.
"By 1944 most casualties were receiving treatment within hours of wounding, due to the increased mobility of field hospitals and the extensive use of aeroplanes as ambulances. The care of the sick and wounded had also been revolutionized by new medical technologies, such as active immunization against tetanus, sulphonamide drugs, and penicillin."

In the 1950s new psychiatric drugs, notably the antipsychotic chlorpromazine, were designed in laboratories and slowly came into preferred use. Although often accepted as an advance in some ways, there was some opposition, due to serious adverse effects such as tardive dyskinesia. Patients often opposed psychiatry and refused or stopped taking the drugs when not subject to psychiatric control. There was also increasing opposition to the use of psychiatric hospitals, and attempts to move people back into the community on a collaborative user-led group approach ("therapeutic communities") not controlled by psychiatry. Campaigns against masturbation were done in the Victorian era and elsewhere. Lobotomy was used until the 1970s to treat schizophrenia. This was denounced by the anti-psychiatric movement in the 1960s and later.
This week on the Evolution of Medicine podcast continues our “Success Leaves Clues” series, “From Matrix to Action” and welcome former Functional Forum guest Dr. Lara Salyer of Health Innate. Dr. Salyer, DO was featured on the Functional Forum this year, is an enthusiastic member of our Practice Accelerator program, and runs a functional medicine practice in rural Wisconsin.
