The current New Yorker unfolds an engaging story on childhood food allergies. As related by Dr. Jerome Groopman, there’s a shift in how some doctors think about how these conditions are best managed and, even better — might be prevented. The article feeds into recent discussion that medical science, and even dogma, too-often turns out to be incorrect.
Groopman interviews Dr. Hugh Sampson, director of the Jae Food Allergy Institute at Mount Sinai Medical Center in New York:
…“This increase in the incidence of food allergy is real,” Sampson said when we spoke recently. He cannot say what is causing the increase, but he now thinks the conventional approach to preventing food allergies is misconceived. For most of his career, he believed, like most allergists, that children are far less likely to become allergic to problematic foods if they are not exposed to them as infants. But now Sampson and other specialists believe that early exposure may actually help prevent food allergies.”
I recommend the full read if you can get it: Groopman probes potential causes of discordant food allergy rates in children of different geographic regions. I learned a number of details on how some doctors in the U.S. use protein-breakdown methods to desensitize children to food allergies, how in Israel newly-speaking infants are said to ask eagerly for Bamba, a manufactured, peanut-containing snack (which, for the record, I don’t particularly endorse), and how in some cultures parents chew their young children’s food in a manner that might that might facilitate breakdown of complex proteins by enzymes in saliva.
All interesting. Of course it’s hard to know exactly what’s true in this, and the causes of allergies are likely to vary among children. There’s a randomized LEAP study (Learning Early About Peanut Allergy) in the U.K. that may provide some hard evidence on this, one way or another.

Luc Montagnier received the 2008 Nobel Prize for his discovery of the human immunodeficiency virus (HIV), but now he’s come up with a more-than-strange theory. He thinks DNA can teleport from one tube to another via electromagnetic signals. Is this the so-called “Nobel disease?”
French virologist Luc Montagnier stunned his colleagues at a prestigious international conference when he presented a new method for detecting viral infections that bore close parallels to the basic tenets of homeopathy.
Although fellow Nobel prize winners — who view homeopathy as quackery — were left openly shaking their heads, Montagnier’s comments were rapidly embraced by homeopaths eager for greater credibility.
Montagnier told the conference last week that solutions containing the DNA of pathogenic bacteria and viruses, including HIV, “could emit low frequency radio waves” that induced surrounding water molecules to become arranged into “nanostructures.” These water molecules, he said, could also emit radio waves.
He suggested water could retain such properties even after the original solutions were massively diluted, to the point where the original DNA had effectively vanished. In this way, he suggested, water could retain the “memory” of substances with which it had been in contact — and doctors could use the emissions to detect disease.

I’ve followed in bits and pieces — sometimes for Shrink Rap, sometimes because the issues fill my email inbox, sometimes because there’s no escape. Oh, and lots of the players have familiar names.
In the December 27th issue of Wired magazine, Gary Greenberg writes a comprehensive article on the debates around the revision of the American Psychiatric Association’s (APA) upcoming revision of the Diagnostic and Statistical Manual (DSM) entitled “Inside the Battle to Define Mental Illness.” Do read it. Here’s an excerpt:
I recently asked a former president of the APA how he used the DSM in his daily work. He told me his secretary had just asked him for a diagnosis on a patient he’d been seeing for a couple of months so that she could bill the insurance company. “I hadn’t really formulated it,” he told me. He consulted the DSM-IV and concluded that the patient had obsessive-compulsive disorder.
“Did it change the way you treated her?” I asked, noting that he’d worked with her for quite a while without naming what she had.
“No.”
“So what would you say was the value of the diagnosis?”
“I got paid.” Read more »

One of our readers suggested that I review the book The Great Influenza: The Epic Story of the Deadliest Plague in History, by John M. Barry. It’s not a new book (it was published in 2004) but it is very pertinent to several of the issues that we have been discussing on this blog, especially in regards to the current anti-vaccine movement. It’s well worth reading for its historical insights, for its illumination of the scientific method, and for its accurate reporting of what science has learned about influenza.
In the great flu epidemic of 1918, influenza killed as many people in 24 weeks as AIDS has killed in 24 years. It’s hard to even imagine what that must have been like, but this book helps us imagine it. It tells horror stories: Children found alone and starving beside the corpses of their parents in homes where all the adults had died, decomposing bodies piling up because there was no one left who was healthy enough to bury them.
Sometimes the disease developed with stunning rapidity: During one three-mile streetcar trip, the conductor, three passengers, and the driver died. In another incident, apparently healthy soldiers were being transferred to a new post by train: During the trip, men started coughing, bleeding, and collapsing; and by the time it arrived at its destination, 25 percent of the soldiers were so sick they had to be taken directly from train to hospital. Two-thirds of them were eventually hospitalized in all, and 10 percent of them died. The mind boggles. Read more »

In November 2010, the California Department of Consumer Affairs (DCA) finally decided to act responsibly and forbid the prevalent practice of Chinese bloodletting by licensed acupuncturists. The practice became a concern for the DCA when allegations of unsanitary bloodletting at a California (CA) acupuncture school surfaced.
The incident allegedly occurred during a “doctoral” course for licensed practitioners. The instructor was reportedly demonstrating advanced needling and bloodletting techniques. During the process, he took an arrow-like lancing instrument that is called a “three-edged needle” (三棱针), sharpened it with sandpaper, cleaned it with alcohol, and then asked a student-volunteer to roll a towel around his neck. The instructor then cleaned the student’s temporal region with alcohol, and punctured a superficial blood vessel with the arrow-like instrument. The student then held his head over the garbage can, gushing blood for awhile. Read more »
