But there are less obvious ways in which evolutionary principles apply to infectious diseases. It has been known for a long time that sickle-cell trait provides resistance to malaria (the blood cells are less hospitable to the P. falciparum protozoan parasite that is one cause of malaria). This explains the persistence of sickle cell disease in populations where malaria is endemic.
Furthermore during the 18th century a number of hospitals were founded. In 1724 Guys Hospital was founded with a bequest from a merchant named Thomas Guy. St Georges was founded in 1733 and Middlesex Hospital in 1745. Hospitals were also founded in Bristol in 1733, York in 1740, Exeter in 1741 and Liverpool in 1745. The first civilian hospital in America opened in Philadelphia in 1751. In the late 18th century and early 19th century dispensaries were founded in many towns. They were charities were the poor could obtain free medicines.
This week on the Evolution of Medicine podcast, we hear from Richard Morris, CEO of Powell Metabolics. Powell Metabolics is an innovative wellness coaching program delivered in a physical therapy environment that started in Arizona and has the potential to expand across the country. This is part of a greater trend of functional medicine integrating with other "hands on" modalities like physical therapy, personal training and chiropractic. We think you'll be inspired to hear about their process, the results and how your practice could benefit.
In the 1830s in Italy, Agostino Bassi traced the silkworm disease muscardine to microorganisms. Meanwhile, in Germany, Theodor Schwann led research on alcoholic fermentation by yeast, proposing that living microorganisms were responsible. Leading chemists, such as Justus von Liebig, seeking solely physicochemical explanations, derided this claim and alleged that Schwann was regressing to vitalism.
In preparation for next Monday's Functional Forum, The Evolution of Primary Care, we are thrilled to welcome IFM certified practitioner, Dr. Kara Parker to the Evolution of Medicine podcast this week. Dr. Parker has been practicing integrative and functional medicine for almost two decades, and practices in Minnesota at the Whittier Clinic. If you are interested in functional or integrative medicine, particularly how to work with the undeserved, this podcast is not one to miss.
Late antiquity ushered in a revolution in medical science, and historical records often mention civilian hospitals (although battlefield medicine and wartime triage were recorded well before Imperial Rome). Constantinople stood out as a center of medicine during the Middle Ages, which was aided by its crossroads location, wealth, and accumulated knowledge. copied content from Byzantine medicine; see that page's history for attribution
This was a common scenario in wars from time immemorial, and conditions faced by the Confederate army were even worse. The Union responded by building army hospitals in every state. What was different in the Union was the emergence of skilled, well-funded medical organizers who took proactive action, especially in the much enlarged United States Army Medical Department, and the United States Sanitary Commission, a new private agency. Numerous other new agencies also targeted the medical and morale needs of soldiers, including the United States Christian Commission as well as smaller private agencies.
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.
During the 16th century there were some improvements in medicine. However it remained basically the same as in the Middle Ages. Medicine was still dominated by the theory of the four humors. In 1546 a man Girolamo Fracastoro published a book called On Contagion. He suggested that infectious diseases were caused by 'disease seeds', which were carried by the wind or transmitted by touch. Unfortunately there was no way of testing his theory.
The Greeks also knew that diet and exercise and keeping clean were important for health. Later Alexander the Great conquered Egypt. In 332 BC he founded the city of Alexandria and a great medical school was established there. Doctors in Alexandria dissected human bodies and they gained a much better knowledge of anatomy. However little progress was made in understanding disease.
1897 Ronald Ross, a British officer in the Indian Medical Service, demonstrates that malaria parasites are transmitted via mosquitoes, although French army surgeon Charles Louis Alphonse Laveran identified parasites in the blood of a malaria patient in 1880. The treatment for malaria was identified much earlier (and is still used today). The Qinghao plant (Artemisia annua) was described in a Chinese medical treatise from the 2nd century BCE; the active ingredient, known as artemisinin, was isolated by Chinese scientists in 1971 and is still used today. The more commonly known treatment, quinine, was derived from the bark of a tree called Peruvian bark or Cinchona and was introduced to the Spanish by indigenous people in South America during the 17th century.
As we prepare to refocus on this topic during the February 2017 Functional Forum, we take a look back at this special presentation. Dr. Brogan advocates for and empowers women through her women's health focused practice. Physicians are quick to medicate their patients with potent psychotropic drugs. Get the most up-to-date, accurate information on natural ways to improve emotional well-being using food, nutrients and dietary supplements.
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.
1950s: A series of successful anti-psychotic drugs are introduced that do not cure psychosis but control its symptoms. The first of the anti-psychotics, the major class of drug used to treat psychosis, is discovered in France in 1952 and is named chlorpromazine (Thorazine). Studies show that 70 percent of patients with schizophrenia clearly improve on anti-psychotic drugs.
