Key Historical Figures in MedicineEdit
Discuss with your counselor the influence that EIGHT of the following people had on the history of medicine:
Hippocrates of Cos (c. 460 BC - 377 BC) was an Ancient Greek physician, is commonly regarded as one of the most outstanding figures in medicine of all time and has been called the father of medicine.
William Harvey (April 1, 1578 - June 3, 1657) was a doctor who first correctly described in exact detail the circulatory system of blood being pumped around the body by the heart.
Anton van Leeuwenhoek (October 24, 1632 - August 26, 1723) was a tradesman and scientist from Delft, in the Netherlands. He is best known for his contribution to improvement of the microscope and his contributions towards the establishment of cell biology. Using his handcrafted microscope he was the first to observe and describe muscles fibres, bacteria, spermatozoa and blood flow in capillaries (small blood vessels).
Edward Jenner (May 17, 1749 - January 26, 1823) was an English country doctor practicing in Berkeley, Gloucestershire, England, made famous by his invention of the vaccine.
Florence Nightingale (May 12, 1820 - August 13, 1910) - The Lady With The Lamp - was the pioneer of modern nursing.
Louis Pasteur (December 27, 1822 - September 28, 1895) was a French scientist who was a pioneer in microbiology.
Gregor Mendel was born on July 22, 1822, in Heinzendorf, Austria (now Hyncice, Czech Republic). He studied the inheritance of traits in pea plants, discovering the basic laws of inheritance. He is often called the father of genetics.
Joseph Lister, 1st Baron Lister (April 5, 1827-February 10, 1912) was a famous British surgeon who promoted the idea of sterile surgery while working at the Glasgow Infirmary. He came from a rich Quaker home in Yorkshire.
Robert Koch (December 11, 1843 - May 27, 1910) was a German physician. He became famous for the discovery of the tubercle bacillus (1882) and the cholera bacillus (1883) and for his development of Koch's postulates. He was awarded the Nobel Prize in Physiology or Medicine in 1905. He is considered one of the founders of bacteriology.
Wilhelm Röntgen (March 27, 1845 - February 10, 1923) was a German physicist, of the University of Würzburg, who, on November 8, 1895, produced wavelengths of electromagnetic radiation that are now known as x-rays. The machine which Röntgen built to emit these rays, was the x-ray machine.
Marie (November 7, 1867 – July 4, 1934) and Pierre (May 15, 1859 – died April 19, 1906) were pioneers in the early field of radiation. Both were Nobel Laureates in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena.
Walter Reed (September 13, 1851 - November 23, 1902) was an American Army surgeon who led a team which discovered that yellow fever is transmitted by mosquitos rather than direct contact. This insight opened entire new fields of epidemiology and biomedicine and most immediately allowed the resumption and completion of work on the Panama Canal (1904-14) by the United States.
Karl Landsteiner (June 14, 1868 - June 26, 1943), was an Austrian biologist. In 1909 he developed the modern system of classification of blood groups and later identified agglutins and Rhesus factor for which he won the 1930 Nobel Prize in Physiology and Medicine.
Alexander Fleming (August 6, 1881 - March 11, 1955) a Scottish biologist and pharmacologist. Fleming published many articles on bacteriology, immunology, and chemotherapy. His best-known achievements are the discovery of the enzyme lysozyme in 1922 and isolation of the antibiotic substance penicillin from the fungus Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945
Jonas Salk (October 28, 1914 - June 23, 1995) is the discoverer/inventor of the vaccine for Polio which proved to be the first successful vaccine against a virus. The vaccine provides the recipient with immunity against Polio, and was seminal in the near eradication of a once widely-feared disease.
James Watson and Francis Crick are American molecular biologist who are best known as the co-discoverers of the structure of DNA. This earned them the 1962 Noble Prize in Physiology and Medicine and a correct understanding of how "the molecular structure of nucleic acids transfer information in living material".
Explain the Hippocratic Oath to your counselor, and compare the original version to a more modern one. Discuss to whom those subscribing to the original version of the oath owe the greatest allegiance.
- Original text of the Hippocratic Oath:
|“||I swear by Apollo, Asclepius, Hygieia, and Panacea, and I take to witness all the gods, all the goddesses, to keep according to my ability and my judgment, the following Oath. To consider dear to me as my parents him who taught me this art; to live in common with him and if necessary to share my goods with him; To look upon his children as my own brothers, to teach them this art I will prescribe regimens for the good of my patients according to my ability and my judgment and never do harm to anyone. To please no one will I prescribe a deadly drug nor give advice which may cause his death. Nor will I give a woman a pessary to procure abortion. But I will preserve the purity of my life and my arts. I will not cut for stone, even for patients in whom the disease is manifest; I will leave this operation to be performed by practitioners, specialists in this art. In every house where I come I will enter only for the good of my patients, keeping myself far from all intentional ill-doing and all seduction and especially from the pleasures of love with women or with men, be they free or slaves. All that may come to my knowledge in the exercise of my profession or in daily commerce with men, which ought not to be spread abroad, I will keep secret and will never reveal. If I keep this oath faithfully, may I enjoy my life and practice my art, respected by all men and in all times; but if I swerve from it or violate it, may the reverse be my lot.||”|

Visit a physician's office, preferably one who delivers "primary care" (This may be that of your counselor) and do the following:
- Discuss components of a medical history and physical examination (an official BSA health form may be used to guide this discussion), and become familiar with the instruments used.
- If this cannot be arranged, demonstrate to your counselor that you understand the components of a medical history and physical, and discuss the instruments involved.
Describe the characteristics of a good diagnostic test to screen for disease (e.g. routine blood pressure measurement). Explain briefly why diagnostic tests are not perfect.
Each diagnostic tests has different properties or abilities to accurately determine results. A good diagnostic test would be one in which the test is highly reliable for accurately diagnosing the condition of interest, would be inexpensive to administer, and would provide results quickly. In addition to how the test itself performs, one must ask if the result from test can be used to guide subsequent decisions on starting, stopping, or modifying treatment. Consequently, the practical value of a diagnostic test can only be assessed by taking into account subsequent health outcomes. In determining the value of various diagnostic tests, it is important to distinguish between these two features of the test (accuracy of the test itself) and (ability of the test to guide therapeutic decision making in altering health outcomes).
In terms of accuracy, diagnostic tests are judged by several characteristics, including:
|Positive||Condition Present + Positive result
= True Positive
|Condition absent + Positive result
= False Positive
Type I error
|Negative||Condition present + Negative result
= False (invalid) Negative
Type II error
|Condition absent + Negative result
= True (accurate) Negative
Example, using pregnancy test results:
|True Positive||False Positive
(i.e. pregnancy reported
but not present)
Type I error
| Test shows
Type II error
Taking a Blood Pressure ReadingEdit
Show how to take a blood pressure reading and a pulse reading.
Health Care SystemEdit
- Discuss the roles medical societies, the insurance industry, and the government play in influencing the practice of medicine in the United States.
- Medical Societies. These groups, made up of physician members of a designated specialty or common interest, can have a significant influence over the way their specialty is practiced. The traditional role of these societies has been to certify or license or practice in the designated field. Medical societies can be very effective in protecting the interests of the society through political action groups, accelerate the sharing of best practices across the field, and as an organizing influence for ongoing education, specialization, and training.
- Insurance Industry - this industry has a major impact on medicine as it has developed into the primary means (~55%) whereby health care services are paid for. The essential idea behind insurance is to protect against risk - meaning that people are willing to pay insurance companies a known quantity of money (in the form of a monthly/annual "premium") to protect them against unknown medical expenses. Insurers often set the prices, determine if a medical expense meets their criteria for payment, and can significantly influence practice patterns by how they reimburse, or pay, for various healthcare services. Given the way the current insurance industry has been organized, they are often in an adversarial relationship with medical providers and the patients they serve.
- Government. In the United States, the government pays for ~45% of all health care expenses. As a result, they have significant ability to influence the way medicine is practiced, the way that it is paid for, and how the delivery of health care is legislated. Government needs to be careful of this influence, and the traditional accepted role of government is not to intervene with the free market, but rather create an environment of standards, interoperability, and similiar policies that enable
- Briefly tell how your state monitors the quality of health care within its borders, and how it provides care to those who do not have health insurance.
- Monitoring Quality - There are multiple quality organizations in the state of California. Medical Societies police themselves through a combination of licensure, certifcation, and ongoing education. Medical Boards are created as to ensure that standards of care are set and maintained by those who practice within that specialty. In addition, their are multiple public-private initiatives within the state to measure, monitor, and report the quality of care within the State.
- Caring for those with no health insurance - This is an extremely challenging problem as there are more than 45 million people in the United States who do not have health insurance. In California, approximately 7 million people are uninsured. Governor Arnold Schwarzenegger has proposed for sweeping changes in California's health care system to ensure that all Californians can obtain health care insurance. He presented the outline of his proposal in February 2007, and later called a special session of the state legislature in the fall of 2007, to debate the proposal. The essential concept is that we must provide insurance to all through a "shared responsibility" which includes taxes to businesses, hospitals, and physicians; some combination of touch credits/vouchers for the uninsured, and an increased public health awareness on prevention and healthy choices.
Global Health Care DeliveryEdit
Compare and discuss with your counselor the health care delivery systems in the United States, Sweden, and China.
- United States
- In Sweden, the publicly funded medical system is comprehensive and compulsory. Physician and hospital services take a small patient fee, but their services are funded through the taxation scheme of the County Councils of Sweden. There is a small private insurance industry in Sweden.
- WHO Statitics on Sweden
- Some positive results of this form of healthcare
