History of Medicine
Herbalism
There is no actual record of when the use of plants for medicinal purposes first started, although the first generally accepted use of plants as healing agents were depicted in the cave paintings discovered in the Lascaux caves in France, which have been Radiocarbon dated to between 13,000 – 25,000 B.CE.
Over time and with trial and error, a small base of knowledge was acquired within early tribal communities. As this knowledge base expanded over the generations, tribal culture developed into specialized areas. These ‘specialized jobs’ became what are now known as healers or Shaman.
Egyptian Medicine
Medical information contained in the Edwin Smith Papyrus date as early as 3,000 B.C. The earliest surgery was performed in Egypt around 2,750 B.C.
Imhotep in the 3rd dynasty is credited as the founder of ancient Egyptian medicine and as the original author of the Edwin Smith Papyrus, detailing cures, ailment and anatomical observations.
The Edwin Smith Papyrus is regarded as a copy of several earlier works and was written circa 1,600 B.C as an ancient textbook on surgery and describes in exquisite detail in the examination, diagnosis, treatment and prognosis of numerous ailment.
Medical institutions are known to have established in ancient Egypt since as early as the 1st Dynasty. By the time of the 19th Dynasty their employees enjoyed such benefits as medical insurance, pensions, sick leave and worked eight hours per day.
The earliest known physician is also credited to ancient Egypt: Hesrye, ìChief of Dentists and Physicianì for King Djoser in the 27th century B.C. Also the earliest women physician, Peseshet, practiced in Ancient Egypt at the time of the 4th dynasty. Her title was ìLady Overseer of the Lady Physicians.
Indian Medicine
Ayurveda (the science of living), the Vedic system of medicine originating over 3,000 years ago, views health as harmony between body, mind and spirit.
Its two most famous text belong to the schools of Charaka and Sushruta. According to Charaka, health and disease are not predetermined and life may be prolonged by human effort. Sushruta defines the purpose of medicine to cure the diseases of the sick, protect the healthy and to prolong life.
Ayurveda speaks of eight branches: kayachikitsa (internal medicine), shalyachikitsa (surgery including anatomy), shalakyachikitsa (eye, ear, nose and throat diseases), kaumarabhritya (pediatrics), bhutavidya (phychiatry or demonology), agada tantra (toxicology), rasayana (science of rejuvenation) and vajikarana ( the science of fertility).
Before graduation, the student was to pass a test. But the physician was to continue to learn through texts, direct observation (pratyaksha) and through inference (anumana).
In 2001, archeologists studying the remains of two men from Mehgarh, Pakistan, made the discovery that the people of Indus Valley Civilization, even from the early Harappan periods (circa 3,300 B.C), had knowledge of medicine and dentistry.
The physical anthropologist who carried out the examinitions, Professor Andrea Cucina from the University of Missouri-Columbia, made the discovery when he was cleaning the teeth from one of the men.
Chinese Medicine
Chinese 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.
During the golden age of his reign from 2,696 to 2,598 B.C, as a result of a dialogue with his minister, Ch’I Pai, the Yellow Emperor is supposed by Chinese tradition to have composed his Neijing Suwen or Basic Questions of Internal Medicine.
During the Han dynasty, Chang Chung-Ching, who was mayor of Chang-sha near the end of the second century A.D, wrote a Treatise on Typhoid Fever, which contains the earliest known reference to Neijing Suwen.
The Chin dynasty practitioner and advocate of acupuncture and moxibustion, Huang-fu Mi (215-282 A.D), also quotes the Yellow Emperor in his Chia I Ching, 265 A.D.
During the Tang dynasty, Wang Ping claimed to have located a copy of the originals of the Neijing Suwen, which he expanded and edited substancially.
Early European Medicine
Astrology played a very important part in early Western medicine; most university-educated physicians were trained in at least the basics of astrology to use in their practice. As societies developed in Europe and Asia, belief systems were replaced with a different natural system.
The Greeks, from Hyppocrates, developed a humoral medicine system where treatment was to restore the balance of humours within the body. Ancient Medicine is a treatise on medicine, written roughly 400 B.C by Hyppocrates.
Medieval medicine was an evolving mixture of the scientific and the spiritual. In the early middle ages, following the fall off the Roman Empire, standard medical knowledge was based chiefly upon surviving Greek and Roman texts, preserved in monasteries and elsewhere.
Islamic Medicine
The Islamic World rose to primacy in medical science with such thinkers as Ibn Sina (Avicenna), Ibn Nafis and Rhazes. The first generation of Persian superb physicians were trained at the Academy of Gundishapur, where the teaching hospital was the first invented.
The Comprehensive Book of Medicine (Large Comprehensive, Hawi or “al-Hawi” or “The Continence”) was written by the Iranian chemist Rhazes (known also as Razi), the “Large Comprehensive” was the most sought after of all his compositions.
The “Kitab fi al-jadari wa-al-hasbah” by Rhazes, with its introduction on measles and smallpox was also very influential in Europe.
The Mutazilite philosopher and doctor Ibn Sina was another influential figure. His The Canon of Medicine, sometimes considered the most famous book in the history of medicine, remained a standard text in Europe up until its Age of Enlightenment and the renewal of the Islamic tradition of scientific medicine.
Ibn Nafis described human blood circulation. This discovery would be rediscovered or perhaps merely demonstrated, by William Harvey in 1628, who generally receives the credit in Western history.
Modern Medicine
Medicine was revolutionized in the 18th century and beyond by advances in chemistry and laboratory techniques and equipment, old ideas of infectious disease epidemiology were replaced with bacteriology.
Ignaz Semmelweis in 1847 dramatically reduced the death rate of new mothers from childbed fever by the simple experiment of requiring physicians to wash their hands before attending to women in childbirth.
His discovery predated the germ theory of disease. However, his discoveries were not appreciated by his contemporaries and came into use only with discoveries of British surgeon Joseph Lister, who in 1865 proved the principles of antiseptic.
His work is based on the very important discoveries made by French biologist Louis Pasteur who was able to link some microorganisms with disease.
This brought a revolution in medicine. He also devised one of the most important methods in preventive medicine, when in 1880 he produced the vaccine against rabies.
Pasteur also invented the process of pasteurization to help prevent the spread of disease through milk and other foods, whom it’s named after.
Also Pasteur was an individual worker, an unlike his contemporary Robert Koch, regardless, Pasteur was a man who thought laterally and his vaccination for Rabies, was indeed a milestone, but no one still understood in the 1880s the mechanisms for such immunity.
The role of womankind was increasingly founded by the likes of Elizabeth Blackwell, Elizabeth Garret, Florence Nightingale, etc. They showed a previously a male dominated profession, the elemental role of nursing in lessening the aggravation of patient mortality, resulting from lack of hygiene and nutrition. Nightingale, set up the St Thomas hospital, post-Crimea, in 1852.
Robert Koch is considered one of the founders of bacteriology. He is famous for the discovery of the tubercle bacillus (1883) and for his development of Koch’s postulates.
It was not until the 20th century that there was a true breakthrough in medicine, with great advances in pharmacology and surgery. For the great war spurred the usage of Rontgen’s X-ray and the electrocardiograph, for the monitoring of internal bodily problems.
However, this was overshadowed by the remarkable mass production of penicillium antibiotic, which was a result of government and public pressure. The antibiotic prevented the deaths of thousands during the conquest of Vichy France in 1944. The 20th century witnessed a shift from a master-apprentice paradigm of teaching of clinical medicine to a more “democratic” system of medical schools.

What is Papillomavirus
Papillomavirus are small cells that are associated with STD (Sexual Transmitted Disease), Cervical Cancer, and other diseases. They are just 55mm in diameter and at least 10% of young women in England are infected with some type of papillomavirus by the age of 16. There are over 100 types of Papillomavirus, ranging from the harmless ones that cause warts, to others that cause cancer.
About 40 types affect the genital area, and 4 are responsible for some common genital diseases. Types 16 and 18 fall under what is known as “high-risk” types and cause abnormal cells, which lead to cancer. These types, along with about 10 others, are easily transmitted from one person to another by sexual relations or genital contact.
Although using a condom is good protection from most sexual diseases, such as AIDS or HIV, they only offer partial protection from papillomavirus cells. 80% of all women will, at one point or another, become infected with at least one type by the age of 50.
The Papillomavirus infects the skin and mucous membranes, lining the cervix. The progression is slow from abnormal benign cells to cancer and sometimes will lie there undetected for many years, before becoming diagnosed.
A third of all women will die within 5 years of diagnosis, but the statistics are changing, as the medical world advances. Recently a vaccine against papillomavirus cells was released, called Gardasil, which so far, has shown highly encouraging results against some types of papillomavirus. Generally, though, once the abnormal cells have developed into cancer, the two options are surgery or radiation, to eliminate them.
In many cases, there are no symptoms to indicate the status and the only true way to discover if you are in infected is to have an annual Pap Smear by a gynaecologist. The “low risk” types are transmitted either environmentally or by touch, but the body builds up antibodies naturally against them.
Women are not the only ones affect by cancer-causing types of papillomavirus. Men could get penile cancer as well. It is a DNA based virus, which is why certain types advance to cancer. Normal cells grow, divide and die, whereas cancer ones just carry on dividing. This happens because the DNA is damaged, and since DNA is hereditary, the defect can be passed on to one’s children. Being a DNA-based virus, the high-risk papillomavirus attacks the DNA in the cells, causing them to become cancerous.
In order for cervical cancer to take form completely, a woman would need a history of infections with the types involved. The risks are generally quite low and for most the chances of getting a high-risk type of papillomavirus is small. However a simple test once a year will eliminate any doubt with your doctor.

What causes mitral valve prolapse?
Mitral valve prolapse (MVP) is among the most common heart conditions; however it remains something of a puzzle. Although MVP affects about two percent of the population, the cause is unknown. MVP often occurs in people who have no other heart problems, and the condition may be inherited.
The mitral valve is located in the heart between the upper-left chamber (the left atrium) and the lower-left chamber (the left ventricle). The mitral valve consists of two flaps called leaflets.
In normal operation the leaflets open and close in a specific sequence. This allows the blood to flow in one direction, from the atrium to the ventricle. The left ventricle is the heart’s main pumping chamber and pushes oxygen-rich blood into the arteries, which carry the blood throughout the body.
In patients with MVP, one or both of the leaflets are enlarged, and the leaflets’ supporting muscles are too long. Instead of closing evenly, one or both of the leaflets collapse or bulge into the atrium sometimes allowing small amounts of blood to flow back into the atrium. By listening to the heart with a stethoscope, the doctor may hear a “clicking” sound caused by the flapping of the leaflets.
Sometimes, MVP leads to a condition known as mitral regurgitation or mitral insufficiency. This means a large amount of blood is leaking backward through the defective valve. Mitral regurgitation can lead to the thickening or enlargement of the heart wall. This is caused by the extra pumping the heart must do to make up for the backflow of blood. It sometimes causes people to feel tired or short of breath. Mitral regurgitation can usually be treated with medicines, and some people need surgery to repair or replace the defective valve.
Most of the time, MVP is not a serious condition, even when some patients report palpitations or sharp chest pains. Most patients do not need treatment
