The publisher recently sent me a review copy of Quackery: The 20 Million Dollar Duck, by Tony Robertson. My first thought was “Do we really need another book on this subject? Don’t I know all this stuff already?” I was very pleasantly surprised. Robertson has ferreted out an impressive array of facts and details that I wasn’t aware of; and yes, we need as many good books on the subject as we can get. Each author has a somewhat different approach that may appeal to a different audience. Robertson’s book is a worthy addition to the canon. He is a retired gynecologist who practiced, taught, and still lives in Zimbabwe. He is a critical thinker who understands and promotes science-based medicine, and he brings a unique perspective, especially on subjects related to his specialty. The book is not just about charlatans, it’s about non-science-based practices wherever they are found, including in mainstream medicine and in Robertson’s own field of obstetrics and gynecology.
I expected to like the book after I read the Dedication “To those who appreciate the truth fairy rather than the toothed one” and the Acknowledgements: “To my teachers and mentors who encouraged me to think, always to question and only to accept where there is good evidence.” That could serve as a motto for all skeptics, scientists, and critical thinkers to live by: Think, question, and only accept where there is good evidence.

A breakdown of bacterial species from your skin’s microbiome. As a favor to pregnant women expectant fathers teenage boys on the internet everyone, this is the image I went with. Click to macrolaarggen (Ikean for embiggen).
Sometimes a headline will cause me to run through a series of reactions in rapid sequence. For example “Mothers facing C-sections look to vaginal ‘seeding’ to boost their babies’ health”:
Early studies show that swabbing a mother’s vagina and transferring it to her baby’s mouth, eyes and skin may stimulate microbiome development similarly to babies born naturally – and protect it from health issues later in life
I mean ick.
But take a step back. Not really. I tend to think of people like “Pig Pen” in Charlie Brown, shedding skin and bacteria into the environment. If we were to really think about each other’s microbiome, we might not have intimate contact with our significant other. Or any other animal. I always point out, when someone lets their dog lick them, that they (the dog) had probably just licked its rear, AKA dog-ass seeding. And no, a dog’s mouth is not cleaner than a human’s, unless your dog brushes and flosses with greater frequency than you. (more…)
In 1850, one in four American babies died before their first birthday, and people of all ages died of bacterial infections that could have been successfully treated today with antibiotics. Unfortunately, treatments that have effects usually have side effects, and we are seeing problems due to the overuse of antibiotics. They are given to people with viral infections for which they are useless and to food animals to improve their growth. As a result, antibiotic-resistant organisms are evolving and the development of new antibiotics is not keeping up with the threat. This is common knowledge, but we’re starting to realize that there may be other problems with antibiotics even when they are used correctly to save lives.
The rates of obesity, diabetes, asthma, food allergies, hay fever, eczema, inflammatory bowel disease, celiac disease, acid reflux disease, and esophageal cancer are all on the rise. Martin Blaser, MD, director of the Human Microbiome Program at NYU, thinks antibiotics may be to blame, either as a causal or a contributing factor. In his book Missing Microbes: How the Overuse of Antibiotics Is Fueling Our Modern Plagues, he describes some of the fascinating research he and others have been doing to elucidate the role of the more than 100 trillion microbes that live on and in each of us, and the possibility that antibiotics may have a causal role in several of the so-called diseases of civilization.

So many of the posts on this blog are critical and deal with examples of poor science or other problems. I’d like to offer a breath of fresh air in the form of a book by Mark Sloan, MD: Birth Day: A Pediatrician Explores the Science, the History, and the Wonder of Childbirth.
It is a very positive book. Sloan has attended over 3000 deliveries but he has not lost his sense of wonder. He tells us what life is like in the womb – how much the fetus can see and hear – and smell! He explains the labor process. He explains how a fetus has to rapidly adapt to life outside the womb with a number of physiologic changes. He reflects the joy of bringing a new life into a family, and the experience of becoming a father. He delves into the history of childbirth, with fascinating anecdotes about “salting” newborns, Queen Victoria’s influence on obstetric analgesia, and the attempt to keep forceps a proprietary secret of one family.
He shows the many contributions science has made to childbirth, some of the mistakes it made along the way, and how it corrected those mistakes. (more…)
