This is another wonderful book from Dr. Sacks. The subtitle, “Tales of Music and the Brain,” is accurate: we have a charming and informative mixture of stories of patients and the neurophysiology that interprets how music is processed and performed. The book is synthetic in combining cases from his practice, other clinical reports, letters from correspondents, references to medical literature, and even Sacks’s own personal experiences with music.
Sacks finds that humans have a “propensity to music,” something “innate” in human nature, perhaps like E. O. Wilson’s biophilia. “Our auditory systems, our nervous systems,” he writes, “are indeed exquisitely tuned for music” (xi). Although humans have been involved with music for millennia, it is only in the last few decades that medical imaging (functional MRI, PET) has shown what areas of the brain are active when music is heard.
While humans routinely enjoy music, the book emphasizes unusual events and neurological patients, in short, departures from the norm. Sacks—himself a lover of music—reports on his own experiences with hallucinatory music and anhedonia (loss of pleasure) in hearing music. He describes going to hear the great baritone Dietrich Fischer-Dieskau but finding that he could not, on that day, perceive the beauty of the music. Another condition “amusia,” or loss of musical ability, can be chronic, acquired, or temporary.
Some patients have had injuries or diseases of the brain that change how music is perceived. A man hit by lightning is suddenly obsessed with piano music. Another man (who survived a brain infection) has amnesia about many things but can still make and conduct music at a professional level. The concert pianist Leon Fleisher visits Sacks to discuss his dystonia, or loss of muscle function in one hand (with implications for the brain). Rolfing and Botox helped him heal and he returned to two-handed performances.
Sacks discusses other phenomena that involve brain structures, for example, perfect pitch; persons with this ability have “exaggerated asymmetry between the volumes of the right and left planum temporale” (128). People who experience synesthesia (perceiving notes as colors) have cross activation of neurons in different areas of the brain. Professional musicians (and patients with Tourette’s) demonstrate cortical plasticity, that is they have expanded areas of the brain for particular uses. Children with Williams syndrome have brains influenced by a microdeletion of genes on one chromosome; they have some cognitive deficits and also a great responsiveness to music. For some conditions, the brain determines all; for others, behavior components are also important.
Summary:In 1868, a man named Eben Frost redeems a medal from a pawn shop and delivers it to a widow, Elizabeth Morton (Betty Field). Twenty years earlier her late husband W.T. Morton had used anesthesia on Frost for a dental procedure.
Summary:Ann, the primary protagonist, is diagnosed with and operated on for breast cancer. Her family history leads her to suspect that she may have passed the breast cancer gene on to her daughters-this assertion without having been tested. She retreats from society. Her husband leaves her and she raises two daughters, ever plagued with guilt. The two daughters, as technology advances, choose to have themselves tested. One daughter, tests positive for BRCA-2; the second daughter is not tested, but is diagnosed with breast cancer.
In a future society in which biological reproduction is restricted and humanoid robots ("Mechas") are routinely manufactured to supplement the economic and social needs of humans ("Orgas"), Dr. Hobby (William Hurt) creates a prototype child Mecha, David (Haley Joel Osment), who has "neuronal feedback," the ability to love, and "an inner world of metaphor, self-motivated reasoning," imagination, and dreams. David is given to Henry and Monica, a couple whose biological child Martin is incurably ill and cryopreserved, awaiting a future cure.
More specifically, David is created out of Hobby's own loss and given to aid Monica's mourning for Martin, whom she has been unable to "let go" of as dead. It is thus Monica (Frances O'Connor) who must make the decision to perform the "imprint protocol" that will make David love her. After she stops resisting the desire to love a child (of any kind) again and implements the protocol, Martin is unexpectedly cured and comes home.
The ensuing turmoil sends David, accompanied by a robot Teddy bear, out into a nightmare world of adult Mechas, comprised of both Rouge City, where functioning Mechas like Gigolo Joe (Jude Law) do their sex worker jobs and also the fugitive realm where unregistered, discarded Mechas try to find the spare parts they need to rebuild themselves and elude trappers who take them to reactionary "Flesh Fairs" where they are publicly destroyed as an expression of rage against artificial technologies.
Joe and David, both set up and betrayed by humans jealous of their superiority at performing human functions, join together on a quest to make David "real" and return him to Monica. The quest takes them to a partly submerged Manhattan and sends David and Teddy two thousand years into the future to resolve the dystopic narrative.
Summary:Part of a series, "Letters to a Young . . . [fill in the career]," this collection of essays by pediatrician-author Perri Klass is addressed to her son Orlando during the recent period when he was applying to medical school. The essays follow a chronological sequence, beginning with the decision to apply to medical school, the first two years of medical school, learning how to examine and talk to patients, residency training, physicians as patients, making mistakes, grappling with the most fundamental human issues in medicine, and the mingling of professional work and life.
First published in 1991, and available in reprint edition, this is a compendium of selected artworks and excerpts of diverse medical and literary writings from pre-Hippocratic times to the end of the 20th C. Each chapter integrates selections from medical or scientific treatises, with commentaries written by historians, essays by physicians and writers, and prose and poetry by physicians and by patients. The 235 images in this book include illustrations from medical textbooks and manuscripts, as well as cartoons, sculptures, paintings, prints and sketches. The colour illustrations are stunning and copious, and provide a visual narrative that resonates with each chapter of the book.
The first part of the book, Traditional Medicine, includes chapters on Ancient, Medieval, Renaissance, and Enlightenment medicine. These serves as a preamble for the second part, Modern Medicine, which includes art, medicine and literature from the early 19th century to the end of the 20th century.
The chapter “From the Patient’s Illness to the Doctor’s Disease” illustrates the rise of public health and scientific research with excerpts from works by Edward Jenner, John Collins Warren, René Laënnec, and John Snow, together with experience of epidemic diseases described by writer Heinrich Heine in his essay on “Cholera in Paris”. The chapter on “Non-Western Healing Traditions” includes botanical research by Edward Ayensu, a short story by Lu Hsun and the writing and paintings of George Caitlin on North American Indian healing.
In the patient-focused chapter, “Patient Visions: The Literature of Illness,” are stories of sickness by Thomas DeQuincey, Leo Tolstoy, Giovanni Verga, Katherine Mansfield, André Malraux, and Robert Lowell. The chapter which follows, “Scientific Medicine: the Literature of Cure,” provides the medical counterpoint with personal correspondence by Freud, medical treatises by Wilhelm Roentgen and Louis Pasteur, an essay on surgical training by William Halsted, and an excerpt from George Bernard Shaw's play, Too True to Be Good, in which a microbe takes centre-stage.
There are chapters on “Medicine and Modern War,” which includes personal writing by nurses Florence Nightingale and Emily Parsons, and poems by Walt Whitman, and Emily Dickinson, and “Art of Medicine,” with works by Arthur Conan Doyle, Anne Sexton, James Farrell and W.P. Kinsella.
The final chapter, “The Continuing Quest for Knowledge and Control,” contains no medical treatises but rather ends with personal reflections by the writer Paul Monette on AIDS, and by physician-writers, John Stone, Sherwin B. Nuland, Lewis Thomas, Dannie Abse, and Richard Selzer.
In How Doctors Think, Jerome Groopman explores clinical decision making with a particular emphasis on the poor communication skills and cognitive errors that often lead to misdiagnosis and inappropriate treatment. He uses a narrative approach, filling the book with compelling stories that illustrate the world of patient-physician interactions. Why did a second doctor quickly conclude that Blanche Begaye suffered from aspirin toxicity, while her first doctor mistakenly diagnosed viral pneumonia? Why did several physicians fail to diagnose Maxine Carlson's ectopic pregnancy until the day it ruptured? Groopman's storytelling skill permits him to convey complex concepts (e.g. availability bias, anchoring, and Ockham's razor) through conversation and narrative.
Three major themes run throughout the book, and each is presented with several variations. The first theme is that doctors who don't listen to their patients are likely to make serious mistakes in diagnosis and treatment. The second is that doctors frequently don't have the self-awareness to understand their own errors, especially those that involve dealing with ambiguity and understanding the importance of emotions. The final theme is that that patients ought to be active participants in their own care. This is not a new message, but Groopman frames it in a new way. Given the complexity of clinical decision making, and the many cognitive errors physicians may fall prey to, patients can improve their own care by helping their doctors minimize or avoid such errors. Among other things this means asking thought-provoking questions like "What else could it be?", "What is the worst thing it could be?," or "Is it possible I have more than one problem?"
The poet beautifully captures the connection between a successful neurosurgical operation that restores "the jitterbug of impulses" of the brain, with the neighbors' "word of the cure." He likens the neighbors' conversations to "the way, in Montana prairie country, / the first telephones let the local secrets / and sorrows pour through the survey-staked / barbed-wire fences now doubling / as makeshift transmission lines."
This collection of essays by surgeon-writer Atul Gawande (author of Complications: A Surgeon's Notes on an Imperfect Science --see annotation) is organized into three parts (Diligence, Doing Right, and Ingenuity) and includes an introduction, an afterword entitled "Suggestions for becoming a positive deviant," and reference notes. Each part is comprised of three to five essays, which illustrate, as Gawande explains in the introduction, facets of improving medical care - hence the title of the collection: Better: A Surgeon's Notes on Performance. In typical Gawande style, even the introduction contains tales of patients - a woman with pneumonia who would have fared far worse had the senior resident not paid close and particular attention to her well-being, and a surgical case delayed by an overcrowded operating room schedule. Such tales are interwoven with the exposition of themes and the detailing of the medical and historical contexts of the topic at hand.
The essays, though loosely grouped around the improvement theme, can easily be read as individual, isolated works. The concerns range widely both geographically (we travel to India and Iraq as well as roam across the United States) and topically. For instance, we learn about efforts to eradicate polio in rural south India and the dedicated people who devise and implement the program. Another essay, far flung from the plight of paralyzed children, is "The doctors of the death chamber," which explores the ethical, moral and practical aspects of potential physician involvement in the American system of capital punishment (from formulating an intravenous cocktail ‘guaranteed' to induce death to the actual administration of such drugs and pronouncement of death).
In sum, the topics of the eleven essays are: hand washing, eradicating polio, war casualty treatments, chaperones during physical examinations, medical malpractice, physician income, physicians and capital punishment, aggressive versus overly-aggressive medical treatment, the medicalization of birth, centers of excellence for cystic fibrosis treatment, and medical care in India. The afterword comprises five suggestions Gawande offers to medical students to transform themselves into physicians who make a difference, and by including this lecture in the book, what the reader can do to lead a worthy life.
Tracy Kidder met Paul Farmer in 1994 when the former was writing an article about Haiti. They next met again in 1999 but it was only when Kidder expressed an interest in Farmer and his oeuvre that Farmer emailed him back, writing "To see my oeuvre you have to come to Haiti" (17). Kidder did just that, following the peripatetic workaholic Farmer to Peru, Russia, Boston, and wherever Farmer flew, which is anywhere there is poverty and disease, especially infectious disease.
In Mountains Beyond Mountains (MBM), Kidder chronicles Farmer’s childhood, medical school years (almost a correspondence course with Farmer’s frequent trips to Haiti), his founding of Partners in Health (PIH) and the construction of the medical center in Cange, Haiti, where "Partners in Health" becomes Zanmi Lasante in Creole.
The story of Farmer’s crusade for a more rational anti-tuberculosis regimen for resistant TB; his political struggles to wrestle with drug manufacturers to lower the price of these and medicines for HIV; his charismatic establishment of a larger and larger cadre, then foundation of co-workers; the story of Jim Kim, a fellow Harvard infectious disease specialist; Farmer’s marathon house calls on foot in Haiti; endless global trips punctuated by massive email consultations from all over the world; and gift-buying in airports for family, friends and patients--these are fascinating reading. In the end one is as amazed and puzzled by the whirlwind that is Paul Farmer--surely a future Nobel Peace Prize laureate like Mother Teresa--as Tracy Kidder was and grateful to have the opportunity to read about it by such an intelligent writer.
