palmd | January 24, 2010Tragedy can bring out the best and the worst in humanity. The Haitian earthquake has seen an outpouring money (the most needed type of aid) and other emergency aid. A few days ago I pondered what sort of quackery would emerge to fill a need that doesn't exist.
Homeopaths responded, of course, and while clean water is always needed, clean water that comes with a fairy tale is not.
Every person that lands in Haiti to provide "aid" also brings a mouth to feed and a cloaca to empty, so every body who goes better have a lot of value to deliver. That's why the arrival of Scientology…
oracknows | January 23, 2010Oh, yes, my brothers and sisters, we have done it!
My pharma paymasters are very, very pleased indeed with me and all of their other blogging and Twittering minions. Very, very pleased indeed. In fact, they are cackling with glee over the discomfiture of one of their greatest enemies, Mike Adams, a.k.a. The Health Ranger! This brave rebel's plan to attack the conspiracy by winning a Shorty Award in Health has been thwarted, thanks to the efforts of you and me, oh my brothers and sisters, and The Health Ranger has gone completely mental about it:
I was set to take the top prize, and Dr.…
oracknows | January 22, 2010One week ago, The Chicago Tribune added yet another excellent addition to its recent series of articles exposing the dark underbelly of the anti-vaccine movement and, more importantly, the quackery that permeates the "autism biomedical" movement promoted by anti-vaccine groups such as Age of Autism. The first installment in the series, written by Tribune reporters Trine Tsouderos and Pat Callahan, examined Mark and David Geier's Lupron protocol for autism (which I had written about three years ago under the title Why not just castrate them?), and the second shone a light under the rock…

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18…
oracknows | January 21, 2010Last night was grant crunch time to get a truly serviceable draft to my collaborators today as promised, leaving enough time to revise it by the February 5 deadline. That means the blog has to take a hit today, which is a shame, because Joe Mercola and Age of Autism have laid down some idiocy this week that I'm just dying to take down. Oh, well, it'll wait, and if it won't I'm sure there'll be new idiocy to take down (or, if I need a break, some good science to discuss) when I come up for air again. (In the case of Mercola, it's part one of a promised three part series; so waiting until he's…

palmd | January 20, 2010There has been much written about the doctor-patient relationship, and specifically how to best maintain a clinical distance while at the same time being empathic and compassionate. This is something individual doctors work on throughout their careers, but something else interests me here.
Most physicians derive enjoyment from helping people. Altruism (a topic way too complex for me to pretend to understand in depth) feels good both from the act itself and from the response one gets from the object of the altruism. This last bit has comes with potential pitfalls.
My job is to help people…
oracknows | January 20, 2010Although I have a Twitter account, I really don't use it all that often, other than having set up an automatic feed to Tweet all my new posts for the blog. True, I do from time to time have flurries of activity (usually when I'm trapped in a particularly boring conference) or am inspired to tweak J.B. Handley or other anti-vaccine kooks when they start Tweeting nonsense, but for the most part I remain a blogging kind of a guy. One could argue whether it's my tendency towards logorrhea on the blog rendering me incapable of hewing to the 140 character limit for Twitter, but whatever the reason…
oracknows | January 19, 2010I'd like to start this post by thanking a commenter named Paul Grenville. He provided me with this blogging material and, indeed, may have supplied me with material for two blog posts. He did it by showing up in an old post about a homoepath named Jeremy Sherr, who has been bringing woo to the natives, so to speak, by treating HIV/AIDS patients in Africa with homeopathy. Sherr, as you may recall, Sherr had announced his plans to do "clinical trials" using homeopathy for HIV/AIDS and even bragged about treating Tanzanians with quackery. He then tried--shall we say?--to revise history by making…
palmd | January 18, 2010I had the good fortune of spending a woefully-insufficient amount of time with author Rebecca Skloot at ScienceOnline10 last weekend. Rebecca has worked for the last decade on a remarkable book which is being released next month, but thanks to a quick hand on the keyboard, an active twitter account, and a glass of Merlot (don't ask) I have an advance copy. (I had already pre-ordered one, which I will likely give away in some sort of selfless act of tzedakah.)
The book is called The Immortal Life of Henrietta Lacks and documents one of the most important discoveries in modern biology and the…
palmd | January 18, 2010The current tragedy in Haiti may turn out to be one of the worst natural disasters (if not the worst) the Western Hemisphere has seen in the post-colonial era. Immediate deaths caused directly by trauma from the quake itself will likely number in the tens of thousands but we can be pretty sure that there's more horror to come. This is a tragedy which is going to continue for months---probably years---to come.
Science-based medicine has taught us much about how to mitigate disasters such as this one. Unfortunately, in Haiti medicine is only part of the problem; the long-standing political…
oracknows | January 18, 2010The double standard of the anti-vaccine "autism biomed" movement never ceases to amaze me.
Imagine if you will, that a pharmaceutical company examined a chemical used for industrial purposes. Imagine further that the chemical this pharmaceutical company decided to look at originated as an industrial chelator designed to separate heavy metals from polluted soil and mining drainage. Imagine still further that that pharmaceutical company wanted to use that chemical as a treatment for autism, a chelator to be given to children. Finally, imagine that the drug company was giving this chemical to…
razib | January 17, 2010New genetic loci implicated in fasting glucose homeostasis and their impact on type 2 diabetes risk:
Levels of circulating glucose are tightly regulated. To identify new loci influencing glycemic traits, we performed meta-analyses of 21 genome-wide association studies informative for fasting glucose, fasting insulin and indices of beta-cell function (HOMA-B) and insulin resistance (HOMA-IR) in up to 46,186 nondiabetic participants. Follow-up of 25 loci in up to 76,558 additional subjects identified 16 loci associated with fasting glucose and HOMA-B and two loci associated with fasting insulin…

Although there's been plenty of woo this week (Harriet Denz-Penhey, anyone?), it hasn't been the truly entertaining woo that I so love, you know, the kind of woo of Your Friday Dose of Woo, my long-standing (albeit now intermittent) excursion into the depths of alt-med silliness so over-the-top that it requires--nay, demands!--some serious not-so-Respectful Insolence, but in a more light-hearted way. After all, it's Friday, and what better way to get ready for the weekend than with a little visit to Dr. Orac's Emporium of Quackery and Pseudoscience known as Your Friday Dose of Woo, as long…
razib | January 14, 2010Raising Kids May Lower Blood Pressure:
A new Brigham Young University study found that parenthood is associated with lower blood pressure, particularly so among women.
...
The study involved 198 adults who wore portable blood pressure monitors, mostly concealed by their clothes, for 24 hours.
The monitors took measurements at random intervals throughout the day -- even while participants slept. This method provides a better sense of a person's true day-to-day blood pressure. Readings taken in a lab can be inflated by people who get the jitters in clinical settings. It's a real phenomenon…
palmd | January 14, 2010The great Dr. Sandy Templeton once asked his pathology class, "Why do people go to the doctor?" People came up with all sorts of responses, but to each he gave his best British, "No, no, no, no!" Then he would tell us, "They come to the doctor because they don't feel well and they want you to make it better!"
So obvious. So simple. And yet, so complicated.
As physicians, we have a number of ways of helping patients, only some of which make the patient feel better. Primary and secondary prevention of disease don't necessarily make people feel better in the short run, so they can be…

I love it when a commenter gives me blogging material.
Let's face it. Blogging is a tough hobby. As much as I do love it so, sometimes I'm at a loss for blogging material. Some would argue that when that happens but not me. Why? Because the blogosphere will provide. At least, it has each and every time that I've ever run into difficulties. Of course, it's even nicer when blogging material is delivered up to me right there in the…
oracknows | January 13, 2010People fear chemotherapy.
Some of this fear is not unreasonable, but a lot of it is a vestige of older days, when chemotherapy was much more unpleasant and even at times horrific. However, contrary to the old alt-med trope of chemotherapy as "pure poison" that makes you sicker than cancer, advances in chemotherapy and supportive management that minimizes nausea and other side effects have made chemotherapy easier to bear for many people. Last year, James Randi underwent surgery and chemotherapy for what sounds like colorectal cancer, although he refers to it as "intestinal" cancer. Be that as…
oracknows | January 13, 2010The Onion or real life recommendations by cancer quacks? You be the judge.
Courageous Man Refuses To Believe He Has Cancer
Sometimes The Onion cuts a little too deeply, but this is not too far from "Secret" territory. Unfortunately for wishful thinking, reality doesn't care what you believe and has a way of asserting itself no matter how hard you wish.
