Primary Category: Literature / Plays

Genre: Play

Summary:

In a dramatic monologue, Joanne traces the devastation of a familial proclivity to breast cancer through four generations of women: her grandmother Sarah; her mother; Joanne herself and her two daughters, one of whom is also Sarah.

Joanne’s mother and grandmother both died very young of breast cancer; however, many other family members vanished in the Holocaust and the number of familial cancer deaths is insufficient for her to qualify for genetic testing. Her friend Linda, also a mother of two daughters, learns too late that she carries the BRCA gene; she urges Joanne to be tested.

Tormented by not knowing and equally tormented by what should be done if the test is positive—both for herself and her daughters, she convinces a doctor to lie so that the test can be performed. It is positive; Joanne opts for bilateral preventative mastectomies. During a visit to the gravesite of her mother and grandmother, she begins to explain the genetic risk to her daughters.

Summary:

Kitty Fane is a beautiful young woman whose mother has raised her to make a suitable match. But Kitty refuses a number of suitors; several years pass and eventually she is reduced to marrying Walter, the colonial bacteriologist in Hong Kong. Walter is a shy and awkward man who loves Kitty passionately, but has no idea how to express it; Kitty is charming and socially adept, but vacuous. In Hong Kong Kitty engages in a yearlong affair with Charles Townsend, the assistant colonial secretary, and a married man whose celebrity potential far eclipses Walter's stolid scientific work. The novel opens when Walter discovers his wife's infidelity.

Kitty believes that Townsend is madly in love with her and prepared to divorce his wife and sacrifice his career to marry her. Walter, who suffers from a broken heart, gives Kitty an ultimatum--either Townsend must promise to divorce his wife and marry her, or Kitty must accompany Walter to a city in the interior where he has volunteered to go to fight the cholera epidemic. Townsend demurs; Kitty is crushed; and the desperately unhappy pair travels to the cholera-ridden city, where they move into the house of the newly-dead missionary.

There, Walter (who is also a medical doctor) sets to work, day and night, to institute public health measures and care for dying patients. Meanwhile, Kitty meets Waddington, the British consul, a cynical alcoholic, who is at heart a good and honest person; and the French nuns, who labor tirelessly to care for orphans and the ill. Impressed by the nuns' selflessness, Kitty begins to devote herself to assisting them and trying to understand their spirituality.

When he learns that Kitty is pregnant, Walter asks if it is his child; Kitty responds, "I don't know." This completes the destruction of Walter's heart, and he soon dies of cholera--presumably as a result of experimenting on himself to find a cure. Kitty learns that the nuns, the soldiers, and all the people of the city consider Walter a saint, who has sacrificed himself for their welfare. However, while Kitty has learned to respect her husband, she could never love him.

Kitty stays only briefly in Hong Kong before returning home to London. Shortly before her arrival, she learns that her mother, whom she believes is responsible for her (Kitty's) shallowness, has died. The novel ends with Kitty vowing to bring up her daughter as a strong and independent woman, and preparing to move with her father to the Bahamas, where he has recently been appointed Chief Justice.

Genre: Autobiography

Summary:

The author was the first blind physician to be licensed in Canada. Her autobiography is also an autopathography.

From her anger over developing severe diabetes as a teenager, through her relentless pursuit of a scientific degree and medical school, through a brief failed marriage – followed by the tragedy of completely losing her sight while still in training, to a rewarding and responsible career as a palliative care physician and educator.

Sustained by her religious faith and by loyal family members and friends, Poulson explains choices, compromises and supports that allowed her to continue studying and working in Montreal and later in Toronto.

Her complications from diabetes were numerous, and included heart disease for which she required surgery. Then she developed breast cancer, which eventually metastasized. In closing her narrative, she knows it will likely take her life.

Genre: Memoir

Summary:

This remarkable memoir/natural history chronicles the author's observation of a snail that occupies the flower pot at her bedside during a long immobilization due to chronic fatigue syndrome.  For months of relative isolation, she observes the habits of the snail and begins to research the lives, habits, species, and idiosyncrasies of snails by way of getting to know this one in greater specificity.  As she puts it, "When the body is rendered useless, the mind still runs like a bloodhound...," (p. 5) and her mind certainly does.  Peering into poetry and story as well as biology, she discovers both facts and lore about the lives of snails to complement her intimate curiosity about the life of this snail.  Along the way, and very much by the way, she reflects on the nature of her own complex illness, the likely brevity of life she has now to expect, and how to learn from another species how to live in time differently.

Annotated by:
McEntyre, Marilyn

Primary Category: Literature / Nonfiction

Genre: History

Summary:

Parts of medical history read like detective novels.  The discovery of the source of cholera by Dr. John Snow in London in 1854 is one of those episodes.  The Ghost Map tells the story of Snow's pioneering work in what have now become standard epidemiological methods.  Tracing a cholera outbreak to a local pump in a poor section of London involved many door-to-door visits working with people who weren't always cooperative, incurring the suspicion and/or ridicule of both them and the medical professionals with whom he worked.  In the course of the story the author offers reflections on the organization of cities and on public hygiene.  Snow, an out-of-the-box thinker, also helped develop surgical anesthesia.

Primary Category: Literature / Fiction

Genre: Novel

Summary:

Mary Sutter has been trained as a midwife by her widowed mother, and has demonstrated an unusual aptitude.  She is an eager learner, but her deepest desire is to be a surgeon.  No medical school will take her, however.  As reports reach her home town of Albany of the escalation toward civil war around Washington DC, and in the wake of a disappointment in love,  she decides to board a train and offer her services to Dorothea Dix as a nurse.  Though Miss Dix refuses her on the grounds of her youth, Mary finds her way into apprenticeship with a surgeon who, as the numbers of injured climb, needs all the hands he can get.  Slowly and grudgingly, he comes to accept her as a competent assistant and, eventually, to teach her as a respected apprentice, and the remarkable companion she has become to him.  She learns surgery in the most grueling circumstances possible, amputating shattered limbs of young men, many of whom die anyway of infection or water-borne diseases.  In the course of her sojourn in Washington she meets John Hay and, through him, President Lincoln, whose compassionate attention she manages to direct to the dire need for medical supplies.  Two men love her not only for her intelligence and courage, but for the passion she brings to the hard-won skill that, though it cannot save her brother from the respiratory illness that is rampant in the camps, or her sister from a disastrous childbirth, saves many lives and makes a wider way for women of her generation who find themselves called to medicine.

Genre: Biography

Summary:

Rosalind Franklin: The Dark Lady of DNA is the biography of the scientist whose research James Watson and Francis Crick needed to elucidate the structure of the DNA molecule.  Even though the discovery has had profound implications for modern medicine, Franklin's contribution to it almost remained obscure.

In 1968 Rosalind Franklin (1920-1958) became visible to the world beyond a small circle of scientists when Watson published The Double Helix (1968), his "personal account" of puzzling out DNA.  If not for Watson's self-incriminating candor about stealing glances at Franklin's research, we might not know how crucial her lucid x-ray diffractions of hydrated DNA were to him and Francis Crick.  However, the account that indirectly acknowledged Franklin's contribution to their work represented her in a patronizing caricature.  Since ovarian cancer took her life a decade before Watson's memoir appeared, others have been left to respond to his version of the DNA story and representation of his female colleague.  Among Franklin's defenders, Brenda Maddox offers the most complete and insightful restoration of the scientist, her research, and her life. 

Maddox's biography draws from not only the many scientific archives and personal papers of scientists Franklin worked with in England, Europe, and America, but also from previously undisclosed letters written by Franklin, her friends, and her family.  Maddox also interviewed Franklin's relatives.  Doing so allowed her to position Franklin's life within the history of her close, extended Anglo-Jewish family, generations of wealthy London publishers and bankers who experienced discrimination.  This history does more than belie some of Watson's hasty assumptions about Franklin's background.  It creates a biography of a complex woman who negotiated biases as a citizen and a scientist.     

The biography is divided into three parts.  The first narrates the story of Franklin's childhood, rigorous education, and successful career before accepting the fateful research post at King's College, London.  She's known for thinking skeptically and working mathematically.  Yet early on she showed an aptitude for three-dimensional thinking and for understanding crystalline structures.   As an undergraduate at Cambridge she speculated about a "'Geometrical basis for inheritance'" (56).

The second section concentrates on the 27 months at King's when she worked uneasily with Maurice Wilkins, who showed her revelatory x-rays of DNA to Watson.   This balanced account of a controversial episode in the history of science offers evidence that Franklin was close to drawing the same conclusion about the structure of DNA that Watson and Crick rushed into print.  This section also accessibly explains the molecular biology of her day and the painstaking physical and intellectual intricacies of making and interpreting x-rays of crystalline molecules. 

The third section reminds us that Franklin had a very productive, though short career after leaving DNA to others.  She directed research programs for the study of plant viruses, and she investigated the polio virus shortly before she died.  Respected scientists, including Crick, praised her research.   Many, unlike Wilkins, liked working with her.  More than 40 years after viewing what's known as Franklin's Photograph 51, Watson publicly acknowledged that seeing it "'was the key event'" in understanding the geometry of DNA (316).  (See the note on Photo 51 below.)

Genre: Treatise

Summary:

This is a huge and wonderful book about cancer, the collection of diseases that sickens people all over the globe and kills many of them. An epigraph to the book states, “A quarter of all American deaths, and about 15 percent of all deaths worldwide, will be attributed to cancer,” but the book also describes medical advances that now heal, prevent, or palliate most forms of cancer.

Mukherjee, a cancer physician and researcher, has several strong themes. He sees cancer as an affliction with a long history, a story worthy of a biography; indeed recent discoveries show it to be rooted in our genes (although external factors such as viruses, asbestos, and tobacco smoke can cause genetic disruption). The story of cancer implies a surrounding triangle, the stories of sick people, treating physicians, and biological researchers, all of which Mukherjee artfully weaves across 472 pages. Cancer has Rohrschach blot qualities: depending on time, place, and role in life, humans have perceived different attributes of cancer. As the book ends, however, there is a coalescence of scientific understanding that is satisfying—although there is certainly more to be learned and we are all still vulnerable to genetic errors and, of course, we are intractably mortal.

Another strand is the nature of stories themselves, their twists and turns, presumed early solutions, and personal and social values embedded in them. Mukherjee threads throughout the book the case of a contemporary kindergarten teacher, Carla Reed, who has a leukemia. He bookends his text with ancient Persian Queen Atossa with (presumably) breast cancer. Reed, healed by the end of the book, was Mukherjee’s patient; Atossa was described by Herodotus: both suffered emotional turmoil because of their disease.  Mukherjee understands the affective dimensions of disease for patients and caregivers alike; literature represents these in various ways, and he quotes in his chapter epigraphs and in his prose many writers who describe human experience deeply: Aleksandr Solzhenitsyn, Susan Sontag, Charles Dickens, Thomas Mann, William Carlos Williams, Carlo Levi, and Italo Calvino, to name a few.

The primary story, however, is the interplay of cancer and a large cast of observers, investigators, doctors, scientists, activists, and government officials. Sidney Farber and Mary Lasker dominate the first 100 pages with their two-decade war against cancer. While surgery—historically dramatic and disfiguring—had been a mainstay for treatment of cancer, Farber pursued a biochemical route, which elaborated into chemotherapy, the second major approach of the late 20th century.

Mukherjee also explains ancient views, Hippocrates’, Galen’s humors, Vasealius’ anatomy, Hunter’s stages, Lister’s antisepsis, and Röntgen’s X-rays, which became the third major approach. By 1980, however, the American “War on Cancer” had not been won.

Further advances in cellular biology and genetics would be needed to make targeted molecular therapy possible.  Mukherjee tells this complicated story clearly and engagingly, showing the human investigators to be personable and dogged in their pursuits.  

Another important approach is prevention. The biostatistical work of Doll and Hill, for example, showed the links between tobacco and lung cancer. Screening, such as Pap smears and mammograms, also saved lives, but the basic cellular understanding still eluded investigators.

The final 150 pages explain the search for and discovery of genetic factors, specifically oncogenes. Harold Varmus and J. Michael Bishop were the leaders, winning a Nobel Prize in 1989. Bert Vogelstein, Judah Folkman, Robert Weinberg and Douglas Hanahan took the work further, opening the doors for such drugs as Herceptin, Gleevec, and Avastin.

Summary:

Candice Millard portrays several figures in the 19th century whose lives came together to change history: newly-elected President of the U.S. James Garfield; the insane would-be assassin Charles Guiteau; Doctor Bliss, the arrogant physician who claimed control of Garfield's care; Alexander Graham Bell, who invented a device to find the bullet; and major political figures of the time. Ironically, Garfield attended the Centennial Exhibition in Philadelphia in 1876 where Joseph Lister was displaying his germ theory of infection and Alexander Graham Bell demonstrated his telephone. But when Guiteau shot Garfield in 1881, the bullets did not kill him.  What killed him after months of suffering was the massive infections caused by the doctors' probing without clean hands or clean instruments. At the autopsy, the doctors saw evidence of massive infections, but the bullet was encysted and harmless. All the probing by the doctors created a tunnel, but it was not the path of the bullet.  "Gentlemen, we have made a mistake," said the doctor.

Genre: Novel

Summary:

This novel takes place during the Ice Age at a time when modern humans (Cro-Magnon) have immigrated into northern Europe and begun to interact with the Neanderthal people, who have already been successful inhabitants of Europe for perhaps 100,000 years. Within several thousand years of this fateful encounter, which took place about 35,000 years ago, the Neanderthal people had completely died out. Early mitochondrial DNA evidence indicated that modern humans are unrelated to the Neanderthal--their gene pool simply disappeared--although more recent studies show that perhaps 2 to 3% of our mitochondrial DNA was inherited from the Neanderthals, who prbably died out as a result of modern humans' greater success in competing for food and other resources.

In this scenario modern humanity originated from a version of the Biblical story of Cain and Abel, of brother "killing" brother, except in the paleontological case the younger brother was responsible for the demise of the elder. Bjorn Kurten, an eminent European paleontologist, used this novel to present his ingenious theory to explain what happened.

The story is told from the perspective of Tiger, a young black (Cro-Magnon) man whose father is killed in a raid by men from another band of blacks. Later, he devotes his life to searching for his father's killer. In the process he travels widely and encounters a band of whites (Neanderthal), a seemingly primitive form of humanity known to Tiger's folk as "trolls." The trolls have a high-pitched, bird-like language that Tiger is eventually able to learn, even though it is virtually impossible for whites (trolls) to learn the black language, because they are unable to articulate the broad range of vowel sounds it includes.

The whites are also different in that their bands are equalitarian, with women playing major leadership roles, while black tribes are strictly hierarchical and patriarchal. Tiger travels with the white band and mates with Veyde, one of its prominent members. However, one day the band is decimated by a marauding black tribe led by the warrior, Shelk.

In the story's climax Tiger carries out a scheme to infiltrate the "bad" tribe and kill Shelk, who he believes is his father's murderer. In fact, ther real murderer was Shelk's twin brother, also called Shelk. The two had used the same name to make it appear that "Shelk" could be in two places at once, thus proving he had supernatural powers. We learn that the Shelk twins had mixed black-white parentage. Children of such unions seem god-like in that they are stronger and more attractive and creative than "normal" people of either group. The "good" Shelk finally finds the white father he has been searching for all his life. And, Tiger lives happily ever after with his white mate Veyde, but their children, though strong and resourceful, will inevitably be sterile.
