Summary:The aim of these reflections on uncertainty in medicine is not to discredit evidence-based medicine or to incite suspicion of the careful and caring processes by which most clinicians arrive at the advice they give. Rather it is to change conversations among practitioners and between them and their patients in such a way as to raise everyone’s tolerance for the inevitable ambiguities and uncertainties we live with. If the public were more aware of the basic rules of mathematical probabilities, how statisticians understand the term “significance,” and of how much changes when one new variable is taken into account—when a new medication with multiple possible side-effects is added to the mix, for instance—they might, Hatch argues, be less inclined to insist on specific predictions. He goes on to suggest that there is something to be gained from the challenge of living without the solid ground of assurances. When we recognize the need to make decisions with incomplete information (a condition that seems, after all, to be our common lot) we may refocus on the moment we’re in and see its peculiar possibilities. Changing the conversation requires a critical look at medical education which, Hatch observes, “measures a certain type of knowledge essential to medical practice, but it consequently engenders a conception of medicine best described as overly certain . . . .”
Summary:This is the third book in a series on the history of medicine and medical education by Kenneth M. Ludmerer, a practicing physician and historian of medicine at Washington University of St. Louis. The first, Learning to Heal: The Development of American Medical Education, published in 1985, dealt with the history of medical schools and medical education in the US from their origins in the 19th century to the late 20th century. In 1999 he published Time to Heal: Medical Education from 1900 to the Era of Managed Care. This book, Let Me Heal: The Opportunity to Preserve Excellence in American Medicine, published in 2015, is a sweeping history of graduate medical education in the United States from its inception to the current day.
Summary:The book offers a detailed account by one of the nation’s leading cancer researchers of developments in chemotherapy over the past several decades, as well as the recent history of surgical and radiation treatments in the “war on cancer”—a term he resisted at first but finally embraced with full understanding of its implications. The narrative touches on many of the writer’s own struggles over economic, political, and moral implications of what a NYT reviewer described as a “take-no-prisoners” approach to cure. He also includes stories about disagreements with other researchers that give some insight into the acrimony that is part of high-stakes science. At the NIH and later as head of the National Cancer Institute, DeVita faced many decisions about distribution of resources, how much to put patients at risk, and whom to include in clinical trials. He provides his own point of view on those controversies frankly. Not much mention is made of the causes of cancer, of nutritional or other complementary approaches, or the environmental factors in the spread of cancer. The strong focus on the book is on the development of chemotherapeutic treatments that have succeeded in raising survival rates, though few current statistics are cited.
Summary:Beginning in 1992, Mark Duxbury and Dean McClellan are high-flying salesmen for Johnson and Johnson, Ortho branch – happily promoting the drug Procrit, (or Epogen -- erythropoietin), for anemia. The drug stimulates the bone marrow to produce more red blood cells. Developed by fledging company Amgen, it was licensed to Ortho for specific uses. Their careers take off, and they earn bonuses and stature, peaking in 1993. Soon, however, Duxbury realizes that he is being encouraged to promote the drug for off-label uses and in higher doses that will enhance sales and profits through kickbacks. He soon realizes that the drug is not safe when used in these situations. People are dying because their unnaturally thickened blood results in strokes and heart attacks.
Summary:When nine-year-old Rob Cole, child of poor 11th-century English farmers, loses his mother, he is consigned to the care of a barber-surgeon who takes him around the countryside, teaching him to juggle, sell potions of questionable value, and assist him in basic medical care that ranges from good practical first-aid to useless ritual. When, eight years later, his mentor dies, Rob takes the wagon, horse, and trappings and embarks on a life-changing journey across Europe to learn real medicine from Avicenna in Persia. Through a Jewish physician practicing in England, he has learned that Avicenna’s school is the only place to learn real medicine and develop the gift he has come to recognize in himself. In addition to skill, he discovers in encounters with patients that he has sharp and accurate intuitions about their conditions, but little learning to enable him to heal them. The journey with a caravan of Jewish merchants involves many trials, including arduous efforts to learn Persian and pass himself off as a Jew, since Christians are treated with hostility in the Muslim lands he is about to enter. Refused at first at Avicenna’s school, he finally receives help from the Shah and becomes a star student. His medical education culminates in travel as far as India, and illegal ventures into the body as he dissects the dead under cover of darkness. Ultimately he marries the daughter of a Scottish merchant he had met but parted with in his outgoing journey, and, fleeing the dangers of war, returns with her and their two sons to the British Isles, where he sets up practice in Scotland.
Summary:Luke Lewis is the son of an itinerant preacher in Upper Canada and a recent medical graduate of Montreal’s McGill University. In 1851, he joins the practice of the aging, Edinburgh-trained Dr. Stewart Christie in Thornhill, Ontario. It is a small village a few miles north of Toronto (now the site of some of the most expensive property in Canada). Christie is tired and leaves Luke alone to work.
Summary:In 1847, one of every six women whose babies were delivered by the medical students and supervising doctors at Allgemeine Krankenhaus (General Hospital) in Vienna died of puerperal fever (also known as childbed fever). In contrast, the incidence of this disease in women delivered by hospital midwives was dramatically lower and puerperal fever was quite rare when mothers had their babies born at home.While a few physicians (most notably Alexander Gordon and Oliver Wendell Holmes) realized that childbed fever was a contagious process, it was Semmelweis who identified the nature of the problem as stemming from the failure of obstetricians and medical students to wash their hands and change their clothing, especially after performing autopsies or doing surgery. He mandated that doctors and students wash with a disinfectant (chloride of lime) before examining any woman in labor.Despite the dramatic reduction of maternal mortality on his obstetrical unit, his ideas and methods were not well received. Semmelweis was reluctant to conduct experiments on animals to prove his theory and resisted publishing his findings in any medical journal. When he finally did write a book, The Etiology, the Concept, and the Prophylaxis of Childbed Fever, it was difficult to read and failed to impress many obstetrical experts.With his health failing and his behavior increasingly erratic and inappropriate, Semmelweis was committed to a state-run mental hospital. He died two weeks later. The official cause of death was sepsis secondary to an infection of his finger. The author is convinced, however, based on the autopsy report and findings upon exhumation of the body in 1963, that Semmelweis was beaten to death by the staff at the asylum. He may well have been suffering from Alzheimer's presenile dementia at the time.
Although Dr. Helman’s untimely death did not permit a final editing by this prodigious writer, the published edition is not a book-in-progress. An Amazing Murmur of the Heart: Feeling the Patient’s Beat represents a powerful and persistent continuation of observations and themes that grew out of medical education, close observations of physicians and patients, and his studies in anthropology. All of these forge an approach to patient care that is out of the ordinary.
As his previous writings suggest, Helman is passionate about medicine but concerned, equally about the emergence of those who fail to listen and to those who might be called techno-doctors. While professing his appreciation of and attraction to the magic machine or computer, he is mindful of its absence of emotion and ambiguity. “For this post-human body is one that exists mainly in abstract, immaterial form. It is a body that has become pure information.” (p. 11)
Chapters are comprised of stories about patients and their care providers, each representing complex facets that defy precise measurement, answers and conclusions. As Helman steadily notes, the physician must be an archeologist:
Most patients present their doctors with only the broken shards of human life—the one labeled infection, disease, suffering and pain each of these shards is only a small part of a much larger picture….the doctor will have to try and reconstruct the rest. (p.66)
In general, the chapters illustrate first an initial review of medical history, and then specific patient stories. Of the two, the story is most important. “Mask of Skin,” for example, begins with an overview of skin from Vesalius to the present: largest organ, stripped bare by anatomists, penetrated by disease, later scanned and X-Rayed, tattooed, re-fitted by surgeons, etc. That said, Helman the physician-anthropologist, moves from science to specific stories about patients whose skin may cover profound experiences, psychic and otherwise, that might be overlooked by a dermatologist. Although skin is involved in each of that chapter’s stories, the willing physician must dig deeper in his observations and caring manner to make more profound discoveries.
In a chapter entitle “Healing and Curing” the author describes an old friend, a practitioner who provides advice about patient care that ”was not included in his medical texts”. Patients are more than a diagnosis dressed in clothes. Doctors must make patients “feel seen, listened to, alive”. Always patients should be regarded as people who happen to be sick. From his admired colleague Helman learned to be an attentive listener to the "tiny, trivial, almost invisible things" in patient encounters and stories. To truly heal as well as cure requires the doctor to empathise with what the patient is feeling thereby requiring both an act of imagination and of the heart. The chapter, of course, continues with with stories that illustrate the points enunciated by his colleague and accepted by his disciple.
