1867 Joseph Lister publishes Antiseptic Principle of the Practice of Surgery, one of the most important developments in medicine. Lister was convinced of the need for cleanliness in the operating room, a revolutionary idea at the time. He develops antiseptic surgical methods, using carbolic acid to clean wounds and surgical instruments. The immediate success of his methods leads to general adoption. In one hospital that adopts his methods, deaths from infection decrease from nearly 60% to just 4%.
After AD 400, the study and practice of medicine in the Western Roman Empire went into deep decline. Medical services were provided, especially for the poor, in the thousands of monastic hospitals that sprang up across Europe, but the care was rudimentary and mainly palliative.[69] Most of the writings of Galen and Hippocrates were lost to the West, with the summaries and compendia of St. Isidore of Seville being the primary channel for transmitting Greek medical ideas.[70] The Carolingian renaissance brought increased contact with Byzantium and a greater awareness of ancient medicine,[71] but only with the twelfth-century renaissance and the new translations coming from Muslim and Jewish sources in Spain, and the fifteenth-century flood of resources after the fall of Constantinople did the West fully recover its acquaintance with classical antiquity.
Like all biological systems, both disease-causing organisms and their victims evolve. Understanding evolution can make a big difference in how we treat disease. The evolution of disease-causing organisms may outpace our ability to invent new treatments, but studying the evolution of drug resistance can help us slow it. Learning about the evolutionary origins of diseases may provide clues about how to treat them. And considering the basic processes of evolution can help us understand the roots of genetic diseases.
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.[78]

1870s	Louis Pasteur and Robert Koch establish the germ theory of disease. According to germ theory, a specific disease is caused by a specific organism. Before this discovery, most doctors believe diseases are caused by spontaneous generation. In fact, doctors would perform autopsies on people who died of infectious diseases and then care for living patients without washing their hands, not realizing that they were therefore transmitting the disease.

When mentioning the Roman influence on the history of medicine, the physician Galen is the most illustrious name. This Greek, granted an expensive education by his merchant father, studied in the medical school at Pergamum and frequented the Aesclepions. In AD161, Galen moved to Rome, where he acted as physician to the gladiators, which allowed him to study physiology and the human body.

Mental illnesses were well known in ancient Mesopotamia,[17] where diseases and mental disorders were believed to be caused by specific deities.[6] Because hands symbolized control over a person, mental illnesses were known as "hands" of certain deities.[6] One psychological illness was known as Qāt Ištar, meaning "Hand of Ishtar".[6] Others were known as "Hand of Shamash", "Hand of the Ghost", and "Hand of the God".[6] Descriptions of these illnesses, however, are so vague that it is usually impossible to determine which illnesses they correspond to in modern terminology.[6] Mesopotamian doctors kept detailed record of their patients' hallucinations and assigned spiritual meanings to them.[17] A patient who hallucinated that he was seeing a dog was predicted to die;[17] whereas, if he saw a gazelle, he would recover.[17] The royal family of Elam was notorious for its members frequently suffering from insanity.[17] Erectile dysfunction was recognized as being rooted in psychological problems.[17]
The Evolution of Medicine provides step-by-step instruction for building a successful "community micropractice", one that engages both the patient and practitioner in a therapeutic partnership focused on the body as a whole rather than isolated symptoms. This invaluable handbook will awaken health professionals to exciting new career possibilities. At the same time, it will alleviate the fear of abandoning a conventional medical system that is bad for doctors, patients, and payers, as well as being ineffectual in the treatment of chronic ailments.
