James Maskell: Absolutely. And Dr. Palevsky, when he spoke at the Functional Forum in March, the conclusion of everything—even though he was going into areas that have not been looked on before—is just what you said: epigenetics take care of these factors. It’s certainly another look at whether injecting viruses into tissue, you know, there’s another potential problematic mechanism there. But certainly, the overall view was that it’s epigenetics. We already know what helps to turn on the right genes and keep us healthy.
The earliest known physician is also credited to ancient Egypt: Hesy-Ra, "Chief of Dentists and Physicians" for King Djoser in the 27th century BCE. Also, the earliest known woman physician, Peseshet, practiced in Ancient Egypt at the time of the 4th dynasty. Her title was "Lady Overseer of the Lady Physicians." In addition to her supervisory role, Peseshet trained midwives at an ancient Egyptian medical school in Sais.
But the most impactful change to the old system is the transition to patient-centered diagnoses. Medicine evolving from a doctor-centered structure to a patient-centered structure and this reflects Dr. Galland's unique contribution to the operating system. In this podcast, Dr. Galland addresses how this new model was developed and why it's such an important part of the evolution of medicine.
Medicine made huge advances in the 20th century. The first non-direct blood transfusion was made in 1914. Insulin was first used to treat a patient in 1922. The EEG machine was first used in 1929. Meanwhile many new drugs were developed. In 1910 the discovered salvarsan, a drug used to treat syphilis was discovered. In 1935 prontosil was used to treat blood poisoning. Later it was discovered that the active ingredient of the dye was a chemical called sulphonamide, which was derived from coal tar. As a result in the late 1930s a range of drugs derived from sulphonamide were developed.
The Romans may not have understood the exact mechanisms behind disease but their superb level of personal hygiene and obsession with cleanliness certainly acted to reduce the number of epidemics in the major cities. Otherwise, they continued the tradition of the Greeks although, due to the fact that a Roman soldier was seen as a highly trained and expensive commodity, the military surgeons developed into fine practitioners of their art. Their refined procedures ensured that Roman soldiers had a much lower chance of dying from infection than those in other armies.
In this review, the endlessness evolution of medical science and medical technology, and its effects on disease metamorphosis and increased life expectancy are discussed. In certain instances, the past will be compared with the present and predictions for the future will be outlined. Further, the constant role of the physician in maintaining the health of human beings is emphasized in this endlessness evolution.
A major breakthrough in epidemiology came with the introduction of statistical maps and graphs. They allowed careful analysis of seasonality issues in disease incidents, and the maps allowed public health officials to identify critical loci for the dissemination of disease. John Snow in London developed the methods. In 1849, he observed that the symptoms of cholera, which had already claimed around 500 lives within a month, were vomiting and diarrhoea. He concluded that the source of contamination must be through ingestion, rather than inhalation as was previously thought. It was this insight that resulted in the removal of The Pump On Broad Street, after which deaths from cholera plummeted afterwards. English nurse Florence Nightingale pioneered analysis of large amounts of statistical data, using graphs and tables, regarding the condition of thousands of patients in the Crimean War to evaluate the efficacy of hospital services. Her methods proved convincing and led to reforms in military and civilian hospitals, usually with the full support of the government.
Greek historian Herodotus stated that every Babylonian was an amateur physician, since it was the custom to lay the sick in the street so that anyone passing by might offer advice. Divination, from the inspection of the liver of a sacrificed animal, was widely practiced to foretell the course of a disease. Little else is known regarding Babylonian medicine, and the name of not a single physician has survived.
The Renaissance brought an intense focus on scholarship to Christian Europe. A major effort to translate the Arabic and Greek scientific works into Latin emerged. Europeans gradually became experts not only in the ancient writings of the Romans and Greeks, but in the contemporary writings of Islamic scientists. During the later centuries of the Renaissance came an increase in experimental investigation, particularly in the field of dissection and body examination, thus advancing our knowledge of human anatomy.
"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."

Retinal neurons and their axon output have evolved to be inside the layer of retinal pigment cells. This creates a constraint on the evolution of the visual system such that the optic nerve is forced to exit the retina through a point called the optic disc. This, in turn, creates a blind spot. More importantly, it makes vision vulnerable to increased pressure within the eye (glaucoma) since this cups and damages the optic nerve at this point, resulting in impaired vision.
1796 Edward Jenner develops a method to protect people from smallpox by exposing them to the cowpox virus. In his famous experiment, he rubs pus from a dairymaid's cowpox postule into scratches on the arm of his gardener's 8-year-old son, and then exposes him to smallpox six weeks later (which he does not develop). The process becomes known as vaccination from the Latin vacca for cow. Vaccination with cowpox is made compulsory in Britain in 1853. Jenner is sometimes called the founding father of immunology.

A revolution of a new age of medicine. It is time to make lifestyle changes, improve our education on what we are putting into our bodies on a daily basis, how often do we get fresh air and exercise, how many hours of restful deep sleep do we receive each night? How about our stress levels? All of these and many more affect us intrinsically but most of us just wait for things to go wrong and then expect the medical professional to make us better. We have got this so wrong it is time to take back responsibility and learn what it truly means to look after our health...mentally, physically and socially. This book is pioneering this change and laying the foundations for the medical profession to step up to the challenge of providing the education and the support that we will all need to make this leap...
Scientists, led by Deborah Hung in the HMS Department of Microbiology and Immunobiology and at Mass General and Brigham and Women’s, show that a detailed RNA signature of specific pathogens can identify a broad spectrum of infectious agents, forming the basis of a diagnostic platform to earlier determine the best treatment option for infectious diseases.
The Islamic civilization rose to primacy in medical science as its physicians contributed significantly to the field of medicine, including anatomy, ophthalmology, pharmacology, pharmacy, physiology, surgery, and the pharmaceutical sciences. The Arabs were influenced by ancient Indian, Persian, Greek, Roman and Byzantine medical practices, and helped them develop further. Galen & Hippocrates were pre-eminent authorities. The translation of 129 of Galen's works into Arabic by the Nestorian Christian Hunayn ibn Ishaq and his assistants, and in particular Galen's insistence on a rational systematic approach to medicine, set the template for Islamic medicine, which rapidly spread throughout the Arab Empire. while Europe was in its Dark Ages, Islam expanded in West Asia and enjoyed a golden age. Its most famous physicians included the Persian polymaths Muhammad ibn Zakariya al-Razi and Avicenna, who wrote more than 40 works on health, medicine, and well-being. Taking leads from Greece and Rome, Islamic scholars kept both the art and science of medicine alive and moving forward.
The roots of modern medicine are in ancient Greece. On the one hand most Greeks believed in a god of healing called Asclepius. People who were ill made sacrifices or offerings to the god. They then slept overnight in his temple. They believed that the god would visit them in their sleep (i.e. in their dreams) and when they woke up they would be healed.
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.
Although there is no record to establish when plants were first used for medicinal purposes (herbalism), the use of plants as healing agents, as well as clays and soils is ancient. Over time through emulation of the behavior of fauna a medicinal knowledge base developed and passed between generations. As tribal culture specialized specific castes, shamans and apothecaries fulfilled the role of healer. The first known dentistry dates to c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. The first known trepanning operation was carried out c. 5000 BC in Ensisheim, France. A possible amputation was carried out c. 4,900 BC in Buthiers-Bulancourt, France.
By the thirteenth century, the medical school at Montpellier began to eclipse the Salernitan school. In the 12th century, universities were founded in Italy, France, and England, which soon developed schools of medicine. The University of Montpellier in France and Italy's University of Padua and University of Bologna were leading schools. Nearly all the learning was from lectures and readings in Hippocrates, Galen, Avicenna, and Aristotle.
