What Nurses Know… About PCOS: Polycystic Ovary Syndrome: The Answers You Need from the People You Trust by Karen Roush (2010)

The ‘What Nurses Know’ series is great if you’re looking for down-to-earth and anecdotal information on a particular medical topic. This one on polycystic ovary syndrome is no exception.

PCOS is a not-very-well understood (or frequently misunderstood) disorder that seems to cluster around a number of different symptoms, mainly menstrual issues, fertility issues, and hormone/endocrine issues. (Even the name of the syndrome is misleading — ovarian cysts are not necessarily a symptom of PCOS.) This book did a good job of sorting through the myths and confusion about symptoms, treatments, and outcomes, while acknowledging how much research still needs to be done on the topic.

‘What Nurses Know… About PCOS’ would be a good place to start if you (or someone you know) have just been diagnosed or you suspect you might have PCOS. And besides,you don’t often get a traditional diagnosis anyway — you tell your doc, “I think I have PCOS,” and they say, “Yeah, probably. That makes sense.” So if you read this book, you’ll be as well-informed as most GPs.

The Ghost Map: The Story of London’s Most Terrifying Epidemic — and How It Changed Science, Cities, and the Modern World by Steven Johnson (2006)

You wouldn’t think a book about a cholera outbreak in 1850s London would be very interesting, but this one certainly was. The narrative describes Dr. John Snow, an anaesthesiologist and researcher, and the Reverend Henry Whitehead, the local cleric, over the course of a week as they investigate the vicious outbreak that hits their city.

Working with what they knew at the time — which, in 1854, wasn’t much — they had to pull so much information together to make any sense of the cholera outbreak: how and where waste is disposed, where residents get their water, who had died (and where and when and how it had happened), did the terrible smell in the air have anything to do with it? At that time, the prevailing thought was that cholera was an air-borne disease, and it mainly affected the poorest and dirtiest members of society. Snow and Whitehead had to do a lot of work to find out where the cholera had come from and how it worked, in order to try to save the Golden Square neighbourhood where the outbreak took place.

The level of detail is phenomenal. Johnson has assembled so many bits and pieces to create this book, and each bit is interesting on its own. Some of these 150-year-old anecdotes are worth the price of admission.

Johnson describes Snow in particular as being a “consillient” thinker — that is, he took what he knew from his research in so many different areas (including biology, sociology, psychology, pharmacology, statistics,…) and made connections between those concrete facts and abstract ideas to translate them to another field: epidemiology research.

Johnson’s brain seems to operate the same way. The art of tanning leather; the propensity among certain ethnic groups to lactose intolerance; information design and mapping; nuclear weaponry; drinking brandy: what could any of these things have to do with cholera? Not much, you’d guess, if you hadn’t read the book.
