Speaking of blog carnivals, the Carnival of Bad History has been posted at Science and Politics. It's a lot like the Skeptics' Circle, only it concentrates on history and how people distort, mangle, and misuse it.
Grand Rounds XXXVI
Grand Rounds XXXVI has been posted at Dr. Sanity. Time again to check out the best of the medical blogosphere, complete with art from the great Leonardo da Vinci.
A blog possessed: How vaccine blogging has taken over
Blogging is odd and fascinating. Sometimes it leads you in directions you never anticipated or intended--and, when it does, it can do so with astonishing speed, sometimes taking you by total surprise. One day, you're blogging about one set of topics, and then a day later you suddenly find your blog dominated by a topic that you neither intended nor foresaw. For example, about one week ago, a reader sent me a link to a post on the Huffington Post that was pushing the usual anti-vaccination rhetoric I hear from activists. That e-mail led me to investigate further and find at least five posts with anti-vaccination rhetoric in the short history of the Huffington Post. Because the Ninth Skeptics' Circle was coming up and I wanted to provide my blog buddy St. Nate (the founder of the Skeptics' Circle) with some good material, I decided to write a rather lengthy post rebutting most of the fallacies in those five articles. I barely finished it in time to submit to the Circle, but finish it I did. I posted it last Wednesday and submitted it to the Skeptics' Circle just under the wire for the deadline.
And, suddenly, I'm an autism blogger.
Since then, I've ended up on an e-mail list from Neurodiversity.com, because of a link I posted to an online petition of theirs. (I don't mind; that's partially what this post is going to be about.) I've also ended up writing more about this issue, being cited by Skeptico and having my posts referenced and posted in the comments section of another anti-vaccination piece on the Huffington Post (something I should have done, but I hadn't realized that this particular article allowed comments, unlike previous ones).
We'll see what happens, but I never intended for this subject to take over Respectful Insolence the way it did. I just thought it would be an interesting piece to submit to the Skeptics' Circle on a subject I knew a bit about. I don't plan on making it a major theme of this blog, when someone like Autism Diva can do it better, but I can't resist one last entry into the fray.
One thing that came up during all this was the question: What's wrong with anti-vaccination activists pushing a link between thimerosal and autism? After all, thimerosal has been removed from all early childhood vaccines other than the flu vaccine (which is not a standard vaccine that is given to all children). If the anti-vaxers were right, we'll soon see the epidemiological link over the next few years, right? Ditto if they're wrong. And it is true, as I pointed out. Indeed, Dr. Gordon and I agree on this; we just don't agree on what the following 5-10 years are likely to show with regard to the epidemiology of such a link. In the meantime, is it such a bad thing to get the mercury out of vaccines?
There's nothing wrong per se (although it probably increased the cost of vaccination for in essence no benefit and left a nice fat juicy opening for the trial lawyers to imply that the fact that the government and vaccine manufacturers have succumbed to activist pressure to remove thimerosal from vaccines proves a link), but there's a price for this removal of thimerosal that anti-vaxers don't like to acknowledge. First, postulating the link when the evidence supporting it was very weak to nonexistent frightened parents, making them unjustifiably suspicious of vaccination and therefore less likely to have their children vaccinated (or, at the very least more resistant to it). Second, suggesting such a link on very weak evidence inflamed the guilt of existing parents, who were told in effect that it was at least partially their fault for their children's autism because they vaccinated their children as advised. Third, the postulating of a probably nonexistent link between mercury and autism opened the doors to the chelation therapy quacks, who use the ineffective treatment of chelation therapy to "remove the mercury" and supposedly "cure" the child of autism, a therapy that is unfortunately spoken of approvingly by some elements of the mainstream media, such as Paul Harvey last Thursday (and that formed the basis of many of the abstracts at the Autism One quackfest in Chicago this weekend). Even if mercury is found to be a major contributor to autism as the epidemiologic evidence comes in over the next five to ten years, it is already known that chelation therapy does not improve autism.
However, there is one more consequence, as pointed out in this open letter to David Kirby, the author of the recent book favorably reporting on those postulating a link between mercury and autism, Evidence of Harm. I got this open letter from the Neurodiversity.com mailing list, and its contents shocked me. The letter tells of a coarsening of the debate through anti-vaccination zealotry, as demonstrated by the advertising campaign for Mr. Kirby's book and the dialog on the message boards on Mr. Kirby's website. An excerpt from the open letter:
Indeed it is, and sadly there are several other examples in the letter of nastiness engendered by Mr. Kirby's book and other sources loudly touting a mercury-autism link. It is likely that Mr. Kirby does not support such viciousness, but we don't know for sure because he does not appear to have condemned it. He may not even know of it. Hopefully, this open letter will inform him of what is going on based on his book and provide an impetus for him to condemn such attacks. In any case, this toxic rhetoric towards parents who have the burden of caring for an autistic child reminds me of some of the rhetoric that another bunch of zealots, animal rights activists, sometimes heap upon people who have benefited from animal research. Such a stigmatizing attitude would be bad enough to subject the parents of autistic children to even if the science justified a link between thimerosal and autism. It is utterly inexcusable when the science does not support such a link. Most anti-vaccination activists don't behave this way, but the hysteria engendered by them emboldens the minority who do. When one is utterly certain that one has The Answer, it then starts to make a sort of sense to conclude that parents who do not subscribe to that "answer" and therefore do not treat their children accordingly are either deluded, careless, or even bad parents doing harm to their children and that they therefore deserve contempt. Parents with autistic children have enough problems; they don't need this one added on top of the difficulties they have to deal with every day raising their children.

The letter tells of a coarsening of the debate through anti-vaccination zealotry, as demonstrated by the advertising campaign for Mr. Kirby's book and the dialog on the message boards on Mr. Kirby's website. An excerpt from the open letter:
I have read many online newsgroup posts (including posts to the EOH list) written by parents of autistic children who do not describe witnessing any specific reaction at the time that shots were administered to their children, but who have become convinced of the vaccine hypothesis due to the publicity efforts of vaccine litigants. These parents are now consumed with guilt that their good-faith decision to vaccinate their children might have had damaging consequences, and rage at those individuals whom they presume misled them and inflicted damage upon their children, whether that guilt and rage are warranted or not.
It is also a legal strategy undertaken with little regard for the potential long-term, stigma-perpetuating impact upon those autistic people and their family members who are not inclined to believe that all autistics are poisoned. I have observed numerous instances in which vocal proponents of the autism=poisoning hypothesis have displayed outright contempt for anyone who might have come to their own conclusions about their and their family members' lives, and I will cite many of these instances in this letter.
For example, here is a comment by Lujene Clark, responding to Kevin Leitch, a British father of an autistic child; she and other EOH list members descended en masse upon Mr. Leitch after a blog entry he had written was mentioned on the list (http://www.kevinleitch.co.uk/wp/?p=146, EOH message 1014):
"...if you remain in denial you don't have to extend yourself or take responsibility to heal your child because it is so much easier to blame 'bad genes' and accept your child's fate. Or worse, try to get your child to accept his "genetic" fate. That is a COP-OUT. Your child deserves better. Get off your lazy bum and start to heal the biomedical problems of your child!!"
When Mr. Leitch stated that he recognized autistic traits in members of his extended family, Mrs. Clark replied,
"it seems apparent from reading your reply there is a history of serious psychiatric illness in your family. My apologies, I would not have attempted to engage in rational discussion had I known you were affected."
Now, this is quite a toxic attitude to have towards disability, towards evidence of the genetic transmission of devalued characteristics, and towards parents who think for themselves.
Indeed it is, and sadly there are several other examples in the letter of nastiness engendered by Mr. Kirby's book and other sources loudly touting a mercury-autism link. It is likely that Mr. Kirby does not support such viciousness, but we don't know for sure because he does not appear to have condemned it. He may not even know of it.

Takin' care of business
Over the Memorial Day weekend, I tried to do a little spring cleaning on my sidebar. I found some dead links and either removed them or fixed them. I also added a few new blogs and websites, and removed several others that I no longer regularly browsed, as well as a few blogs that hadn't been updated in a long time. The "Essential Orac" section was reorganized, with some posts added and a few others removed. Finally, some new Chicklets were added to the sidebar make subscribing feeds of Respectful Insolence in My Yahoo!, My MSN, and Newsgator easier. Overall, the sidebar should be somewhat shorter, more concise, and (hopefully) better organized.
Over the summer I'll continue fiddling with it until I get it to where I want it to be--at least until I finally decide whether to ditch Blogger for something else or not.

Memorial Day
Today is Memorial Day. It is the day set aside to remember those who have died fighting for our nation in its wars. I was debating about what to post today, when I remembered that, two and a half weeks ago, I happened to be in Bethesda for a conference sponsored by the NIH. Because of my interest in World War II history and because I had a few hours hadn't seen the new World War II Memorial before (which had been dedicated on Memorial Day weekend last year), I decided to take the Metro into Washington and check it out before heading home. As regular readers of this blog know, sometimes I succumb to the temptation to engage in some photoblogging. Today it seems appropriate to post some of the pictures I took of the monument.
From accounts in the press and opposition to the choice of a location for the monument, I had had my doubts about the design, but I have to say that seeing it up close and personal, in the context of all the other monuments in the area and with the nearby Reflecting Pool, I was impressed and moved. Fears that critics voiced that the monument would ruin the sight lines between the Lincoln Memorial and the Washington Monument were unfounded. Lining paths leading to the fountains in the center are a number of bas-relief panels by sculptor Ray Kaskey, and the overall effect was serene. My one disappointment was that some of the pools without fountains appeared rather stagnant, with algae. You'd think they could take better care of the monument, which is only a year old.
The photos (click for larger versions, and go here for more):
Overall, this seemed to me a fitting memorial to the hundreds of thousands who died in World War II. On this Memorial Day, between the trips to the beach and the barbecues, let us remember the soldiers who have fought and died in all of our wars.

A sign of the times
In Britain, a cell phone ringtone--"Crazy Frog Axel F," a ring tone based on the sound of a revving Swedish mo-ped--has become a #1 hit, outselling the new single by Coldplay by a four-to-one ratio. Coldplay is reportedly bummed, having hoped to go straight to #1 with their single, "Speed of Sound."
Expect to see more of this, although not among us old farts.

This is so wrong
Apparently, someone thinks it's a good idea to sell a thong for your cellphone...
I'm sorry, but I just don't understand. I can understand the utility of some device or other to hang a phone from, but why on earth make it look like a thong?

More antivaccination puffery on The Huffington Post
A few days ago, I posted a long piece about how antivaccination fallacies are being given wide distribution on the new group celebrity blog, The Huffington Post. I then posted an addendum mentioning for the sake of fairness that at least The Huffington Post allowed one expert to post a rebuttal. Well, as expected, it didn't take long for Dr. Jay Gordon to post his response to the rebuttal. As with his other pieces, it's a relatively content-free post, in which once again Dr. Gordon makes dire insinuations that those who don't believe that the objective evidence supports the contention that mercury in vaccines causes autism are shills for the pharmaceutical industry:
OK, Dr. Gordon, so you think that the American Academy of Pediatrics is biased because of a "cozy" relationship with the vaccine industry? If that's so, then why has the AAP come out for removing thimerosal from vaccines--as you yourself pointed out, "adamantly" for it. (I'd have to guess that it's mainly it's because of activists like you, not because of the experimental evidence for a link, which has always been very weak at best and is becoming weaker and weaker with each new study. Apparently, the AAP's "cozy" relationship with the pharmaceutical industry didn't stop it from recommending this.) I'd also turn Dr. Gordon's insinuation around and ask him if he's ever accepted funds from any groups advocating that thimerosal in vaccines is a major cause of autism. If he has, then perhaps he would explain to me why his "accepting funds while commenting on the issues" himself" is any different from other doctors doing the same.
But what about researchers on the "other" side of the issue. In Dr. Gordon's view, apparently it's not good for one's objectivity to have a financial interest in one side of the issue. Fair enough; most people would probably agree that a researcher shouldn't have a strong financial interest in one side of a question. (Leave aside for the moment that most scientists who don't have a financial interest in vaccines also have concluded that there is no link between thimerosal in vaccines and autism and not just in this country.) Given that, why, then, does it not seem to bother Dr. Gordon in the least that David Geier and Dr. Mark Geier, whose research he once again singles out to cite approvingly and both of whom make a significant part of their livings providing legal counsel and consulting and expert witness services to parents pursuing legal action for alleged "injuries" due to vaccination? Doesn't that count as a financial conflict of interest? Yet Dr. Gordon thinks their research is "excellent." Or why doesn't it bother him that their work has been criticized for sloppiness and methodological flaws and they've been rebuked for risking patient confidentiality while mining the CDC's database.
Oh, wait. I get it. The Geiers are not in the pockets of the pharmaceutical industry (pharmceutical industry: always bad). They're in the pockets of trial lawyers and antivaccination activists (antivaccination activists: always good). They're on the "right" side; so Dr. Gordon appears willing to overlook their blatant conflict of interest, while at the same time making vague insinuations of a conflict of interest against by claiming that most researchers in the field accept funding from pharmaceutical companies that manufacture vaccines.
It looks as though Dr. Gordon is going to be a regular at The Huffington Post. Unfortunately, that means he'll have a huge platform for pushing his antivaccination misinformation. That means he'll also probably be occasionally providing me with ideas for this blog for some time to come. But I'd give up all that material in an instant if he's stop making exaggerated claims for a link between thimerosal and autism that almost certainly doesn't exist.
The American Academy of Pediatrics (of which I have been a member for a quarter century) has a very cozy relationship with the vaccine industry. Most authors and speakers in the vaccine controversy have been paid consultants to the vaccine industry. Most of these researchers still accept funds while commenting on the issues.

I echo the Mad House Madman
A few days ago, the Mad House Madman asked what ever happened to CodeBlueBlog, creator of CSI:Medblogs. I had been wondering the same thing myself, as the blog hadn't been updated since April 20. It used to be one of my favorites and was one of the first I encountered shortly after discovering the medical blogosphere. True, CodeBlue would wander into a bit of conspiracy-mongering from time to time (his posts on Bill Clinton's recent surgery, for example), but CodeBlueBlog was always a good read. (Indeed, I had been meaning to comment on his posts on Mammographic Serfdom for some time now, but somehow never got around to it.) Of course, looking at CodeBlueBlog now, the depressing thing is that, even though the blog hasn't been updated in five or six weeks, he's still averaging only slightly fewer than the same number of hits per day than I do, down from around six times my average in March. Talk about deflating my ego! CodeBlue can leave his blog alone and it takes six weeks for its hit count to fall below mine, which is updated nearly every day, sometimes even three or four times a day.
Oh, well.
However, CodeBlue's mysterious extended absence did get me to thinking about what, if any, obligation a blogger may have to his or her audience if he or she has to discontinue the blog or go on extended hiatus. Consequently, I've come up with a few policies for my blog:
Oh, well.
However, CodeBlue's mysterious extended absence did get me to thinking about what, if any, obligation a blogger may have to his or her audience if he or she has to discontinue the blog or go on extended hiatus. Consequently, I've come up with a few policies for my blog:
- I will post an announcement if I plan on not posting for more than a few days, whether due to vacation, obligations of work (usually impending grant deadlines), or whatever. (Of course, on vacations, if I have Internet access, I will still probably post intermittently every few days. I just can't help myself.)
- I will also include in such announcements the date (or an estimate of the date) that regular posting will resume.
- If, for whatever reason, I ever decide to discontinue this blog or to go on an extended hiatus (longer than a couple of weeks, which is about the longest I'm ever off for a vacation or would ever need for grant crunchtime), I will announce it and provide an explanation.
- If I go more than a week without posting and don't post an announcement, either bad things have happened to my computer or bad things have happened to me.

Needlestick
Alan, a.k.a. Gruntdoc, my favorite ER doc blogger, has an interesting post today regarding getting a needlestick injury. As he points out, it's an occupational hazard of being a doctor, although some specialties (emergency medicine and procedure-oriented specialties like surgery) have a much higher risk than others (psychiatry, radiation oncology, non-interventionalist radiologists, for example). I can totally sympathize with his first thoughts:
Indeed.
Needlesticks are almost inevitable if you're a surgeon. All you can do is to try to take every precaution and keep them to a minimum. However, sooner or later, it will happen. Gruntdoc's post took me back to the worst blood exposure incident I ever suffered, one that still haunts me to this day. Fortunately, given that it was 11 years ago and I've had multiple negative hepatitis B and HIV tests since then, I know I'm no worse for it. I was the senior resident on the trauma service, and a man had come in after a fall from a balcony of about 25-30 feet. He had multiple broken ribs, severe head trauma, and a fractured pelvis. It's unclear what he was doing there or what led to the fall, but he did reek of alcohol. In any case, we had done a diagnostic peritoneal lavage to rule out intraabdominal bleeding (these days, we would have done a quick ultrasound or even spiral CT), and we were working on him, getting ready to take him for a head CT. Over about five minutes, his blood pressure fell to zero and we were unable to get a pulse. It was clear that he was going down. It was decided by the trauma attending that we would do a bedside thoracotomy. Now, for blunt trauma (as opposed to penetrating trauma like gunshot wounds or stabbings), the success rate for bedside/ER thoracotomies is very close to zero, which is why we generally don't do them anymore for blunt trauma. When a patient with extensive blunt trauma loses his vital signs, that's usually all she wrote. It's rare to be able to bring him back, no matter what you do. In retrospect, therefore, it probably wasn't the correct thing to do, as it had such an incredibly small chance of making any difference in this man's outcome. But the attending was new and wanted to "do everything." An older, more experienced attending almost certainly would have simply coded the patient for a while and, if there were no immediate response to our interventions, called the code.
So, I got ready to do the procedure with the intern, and the intern asked if he could do the incision. Fool that I was (this was not one of our more stellar interns, to say the least) or in the heat of the moment, I said yes. And so it began.
The intern made the skin incision, and then, while I was repositioning a retractor, telling him to hold on a second to let me get better exposure, he ignored me and carried the incision deeper--right across the side of my index finger.
I was stunned. I stared at the slice in my glove, the cleanly severed latex edges flapping to reveal the cleanly severed skin beneath. Blood was pooling within the finger of the glove, darkening my finger and slowly leaking out of the gash to mingle with the patient's blood already there. After a couple of seconds, I regained my composure enough to utter a few choice profanities at the clueless intern and throwing him out of the procedure. (Crap! I'm better than that. I should have kept a better eye on the intern--especially this intern. Or I never should have let him do this in the first place!) I quickly regained my composure and continued the futile procedure. When the attending saw what happened, he gloved and gowned up to take over, allowing me to run off to wash out the incision. It was pretty deep, but fortunately, as far as I could tell, not deep enough to damage any nerves or tendons. Sensation distal to the injury was intact, and there were no deficits in my ability to move my finger that might indicate an injury to a tendon. While I was doing that, our attending finally bowed before reality and called the code.
I was royally pissed at the intern, who in his hurry hadn't listened. (Lest you think I was being unduly hard on him, the main reason this intern was not one of our more stellar interns was his recurrent and obnoxious inability or refusal to listen and follow instructions.) I was also really furious at myself, as I should have known better than to let this clown near a knife in an emergency situation. But I was scared too. Even though the odds of getting infected from a single blood exposure incident are very small, I still couldn't help but see visions of my young life being snuffed out prematurely and in a most unpleasant fashion, all because of a stupid mistake. Making the fear level higher, the patient didn't look like the most reputable character in the world, and we later found out that he had a history of polysubstance abuse. I ended up getting a shot of gamma globulin, and sweating it out. Fortunately, much to my relief, his HIV and hepatitis B tests turned out negative (and I found out that I still had a strong antibody titer for hepatitis B from my previous vaccine, anyway). Six months later, my repeat HIV test remained negative, and, in the 11 years since then, I haven't developed hepatitis (there were no tests for hepatitis C back then).
Since then, I've had a couple of more needlestick incidents, despite my best efforts. One of them happened while I was, of all things, aspirating a breast cyst in a nice little old lady. Ironically, in my opinion, the "safety" needles that are used in our hospital now are so cumbersome that I honestly believe they make it more likely I will accidentally stick myself. Ditto the "safety scalpels" (which I've dubbed "Playskool knives"), but that may be a topic for another post. Fortunately, it's been around four or five years since I last had a needlestick incident, and I hope to extend that streak to the rest of my career.
I was going to come up with a pithy ending to the description of this incident, but Gruntdoc summed it up better than what I can come up with right now:
The first thought that flew into my mind: "Crap! I'm better than that." Really, I was terrifically disappointed in myself, and angry I'd made the rookie mistake of not watching the needle in my hand. I handle needles for a living, and they never get me, they get the patient, as intended. That's how it's Supposed To Be.
Indeed.
Needlesticks are almost inevitable if you're a surgeon. All you can do is to try to take every precaution and keep them to a minimum. However, sooner or later, it will happen. Gruntdoc's post took me back to the worst blood exposure incident I ever suffered, one that still haunts me to this day. Fortunately, given that it was 11 years ago and I've had multiple negative hepatitis B and HIV tests since then, I know I'm no worse for it. I was the senior resident on the trauma service, and a man had come in after a fall from a balcony of about 25-30 feet. He had multiple broken ribs, severe head trauma, and a fractured pelvis. It's unclear what he was doing there or what led to the fall, but he did reek of alcohol. In any case, we had done a diagnostic peritoneal lavage to rule out intraabdominal bleeding (these days, we would have done a quick ultrasound or even spiral CT), and we were working on him, getting ready to take him for a head CT. Over about five minutes, his blood pressure fell to zero and we were unable to get a pulse. It was clear that he was going down. It was decided by the trauma attending that we would do a bedside thoracotomy. Now, for blunt trauma (as opposed to penetrating trauma like gunshot wounds or stabbings), the success rate for bedside/ER thoracotomies is very close to zero, which is why we generally don't do them anymore for blunt trauma. When a patient with extensive blunt trauma loses his vital signs, that's usually all she wrote. It's rare to be able to bring him back, no matter what you do. In retrospect, therefore, it probably wasn't the correct thing to do, as it had such an incredibly small chance of making any difference in this man's outcome. But the attending was new and wanted to "do everything." An older, more experienced attending almost certainly would have simply coded the patient for a while and, if there were no immediate response to our interventions, called the code.
So, I got ready to do the procedure with the intern, and the intern asked if he could do the incision. Fool that I was (this was not one of our more stellar interns, to say the least) or in the heat of the moment, I said yes. And so it began.
The intern made the skin incision, and then, while I was repositioning a retractor, telling him to hold on a second to let me get better exposure, he ignored me and carried the incision deeper--right across the side of my index finger.
I was stunned. I stared at the slice in my glove, the cleanly severed latex edges flapping to reveal the cleanly severed skin beneath. Blood was pooling within the finger of the glove, darkening my finger and slowly leaking out of the gash to mingle with the patient's blood already there. After a couple of seconds, I regained my composure enough to utter a few choice profanities at the clueless intern and throwing him out of the procedure. (Crap! I'm better than that. I should have kept a better eye on the intern--especially this intern. Or I never should have let him do this in the first place!) I quickly regained my composure and continued the futile procedure. When the attending saw what happened, he gloved and gowned up to take over, allowing me to run off to wash out the incision. It was pretty deep, but fortunately, as far as I could tell, not deep enough to damage any nerves or tendons. Sensation distal to the injury was intact, and there were no deficits in my ability to move my finger that might indicate an injury to a tendon. While I was doing that, our attending finally bowed before reality and called the code.
I was royally pissed at the intern, who in his hurry hadn't listened. (Lest you think I was being unduly hard on him, the main reason this intern was not one of our more stellar interns was his recurrent and obnoxious inability or refusal to listen and follow instructions.) I was also really furious at myself, as I should have known better than to let this clown near a knife in an emergency situation. But I was scared too. Even though the odds of getting infected from a single blood exposure incident are very small, I still couldn't help but see visions of my young life being snuffed out prematurely and in a most unpleasant fashion, all because of a stupid mistake. Making the fear level higher, the patient didn't look like the most reputable character in the world, and we later found out that he had a history of polysubstance abuse. I ended up getting a shot of gamma globulin, and sweating it out. Fortunately, much to my relief, his HIV and hepatitis B tests turned out negative (and I found out that I still had a strong antibody titer for hepatitis B from my previous vaccine, anyway). Six months later, my repeat HIV test remained negative, and, in the 11 years since then, I haven't developed hepatitis (there were no tests for hepatitis C back then).
Since then, I've had a couple of more needlestick incidents, despite my best efforts. One of them happened while I was, of all things, aspirating a breast cyst in a nice little old lady. Ironically, in my opinion, the "safety" needles that are used in our hospital now are so cumbersome that I honestly believe they make it more likely I will accidentally stick myself. Ditto the "safety scalpels" (which I've dubbed "Playskool knives"), but that may be a topic for another post. Fortunately, it's been around four or five years since I last had a needlestick incident, and I hope to extend that streak to the rest of my career.
I was going to come up with a pithy ending to the description of this incident, but Gruntdoc summed it up better than what I can come up with right now:
Mortality sucks. Mortality through stupidity would be unforgivable, for me, and I resolve to not make any more stupid mistakes.I couldn't have said it better myself. If I could, I would have.

Oh my...
It's stupid stuff like this that gives me migraines:
It boggles the mind. Repeat after me, people: "Evolution is not incompatible with Christianity." Fortunately, the way I learned of this was through Right Thoughts, yet more evidence that not all conservatives buy into the rejection of science that all too many fundamentalists and "intelligent design" creationism apologists are pushing. Unfortunately, it is the fundamentalists who have taken over the Republican Party, and it doesn't look as though they're going to be ousted any time soon. Their anti-science viewpoint is one of the reasons I no longer identify myself as a Republican.

Nice resource on the scientific evaluation of alternative medicine
Professor Thomas J. Wheeler, of the Department of Biochemistry and Molecular Biology at the University of Louisville School of Medicine, has made the classroom handouts and reading lists for his course, A Scientific Look at Alternative Medicine, available online. It's a nice resource for anyone interested in a critical look at alt-med claims, and I can only give Paul at Confessions of a Quackbuster his well-deserved props for having found it.
I wish more medical schools and universities would offer courses like this, and hopefully Professor Wheeler will expand on this resource in the future.
The introduction to his course gives a nice summary of the characteristics of alt-med claims (some of which I've annotated with my own comments in parentheses):
SOME CHARACTERISTICS OF PSEUDOSCIENTIFIC HEALTH CLAIMS
I wish more medical schools and universities would offer courses like this, and hopefully Professor Wheeler will expand on this resource in the future.
The introduction to his course gives a nice summary of the characteristics of alt-med claims (some of which I've annotated with my own comments in parentheses):
SOME CHARACTERISTICS OF PSEUDOSCIENTIFIC HEALTH CLAIMS
- Nonfalsifiable or irrefutable hypotheses. (This is almost essential to not just quackery but pseudoscience in general, like "intelligent design" creationism.)
- Attribute failure to reproduce results to: (1) Failure to perform procedures properly; (2) bias; (3) incorrect attitude. (This is one that I hear again and again in misc.health.alternative. Alties will claim that scientists are biased, that they approach the idea with a "skeptical" attitude--which in my book is entirely appropriate. Scientists should approach such claims with a skeptical attitude.)
- Unwilling to examine the phenomena closely with carefully controlled experiments. (This one is common in all pseudoscience as well. It's particularly common for paranormal phenomenon, but devotees of several altie techniques, like "psychic surgery" or many of the traditional Chinese medicine techniques that rely on Qi, which is basically an vaguely defined "life force" also fall under this rubric, as do quacks like Hulda Clark. How on earth does one measure quantitatively Qi, by the way?)
- Reliance on anecdotal evidence, or on data from flawed studies (poor controls, insufficient sample size, etc.). (This is a big one. Alties will use testimonials to sell their product or berry pick very small studies that seem to show an effect and ignore all the others that do not, as chelationists frequently do.)
- Anecdotal evidence can be very persuasive - especially if it concerns yourself. (True, although in most cases, even the anecdotes are questionable, based on insufficient diagnostic testing, insufficient followup, and neglecting the contribution of previous conventional medical treatments. Often the reason the anecdotes seem convincing because most people do not understand the disease for which the testimonial is being given.)
- Argument from authority rather than evidence - endorsements by doctors, panels, etc. (There's not necessarily anything inherently wrong with arguing from authority if the authority is truly an authority and if the evidence supports it. However, the "authorities" these guys argue from are usually highly questionable at best.)
- Selection of only supportive data, or deletion or changing of unfavorable data. (A favorite. However, in fairness, I will point out that, unfortunately, scientists aren't always above selection of only supportive data to make their case. Other scientists will usually call them on it, though. However, unlike the case with alties, scientists who are caught deleting or changing unfavorable data will suffer severe consequences in their career, their ability to be published, and their ability to obtain funding to support their research. Not so with alties.)
- Confuses correlation with causality. (Chapters of books have been written on this. Repeat after me, everyone, "Correlation does not necessarily mean causality. The antivaccination zealots who claim mercury in vaccines causes autism are prime examples of this pseudoscientific fallacy.)
- "Special pleading" - less stringent rules of evidence should be applied to its claims. (I've seen this one before. Typical is the claim by some alties that there are "different ways of understanding" or "different ways of knowing" other than science. Of course, these "different ways" are almost always less stringent and biased in favor of the "alternative" treatment being discussed. It makes me want to barf when I hear this one.)
- Claim to be too busy healing patients to pursue verification through research. (A great excuse if you can get away with it. I wish I could use this one four years from now, the next time I have to renew my grant. Oh, I'm sorry, Dr. Study Section Director, I was too busy taking care of patients to pursue the research. Somehow I doubt they'd be very sympathetic. This excuse is a cop-out used by alties who are clearly not interested in proving or disproving their claims using empiric evidence.)
- Lack of acceptable confirmation of diagnosis before treatment and/or proper followup to confirm healing. (Another big one. When you see "hair analysis" or "live blood cell analysis" used to diagnose cancer or other medical conditions and then to "monitor" response to treatment and "prove" that it's been cured by altie treatments, you're definitely dealing with a quack." Another example is Hulda Clark's "Syncrometer," which purports to diagnose the presence of toxic compounds by changes in skin resistance.)
- Subjective evaluations or measurements. (See above.)
- Use of pseudomedical jargon: "detoxify," "rejuvenate," "energy," etc. - entities which cannot be measured. (Another favorite pseudomedical piece of jargon among alties is "strengthens the immune system." How many times have you heard the claim that some altie therapy or other "strengthens the immune system"? More times than you can count? Me too. Too bad it's a meaningless claim, as they never get specific. For example, does the therapy improve T-cell function? What is the evidence that it does? Does it improve antibody response? You'll never get a specific answer with evidence to back it up.)
- Proposes a single underlying cause for diverse diseases or conditions. (Hulda Clark is guilty of this in her Cure for All Diseases claims, in which she attributes all cancer to an intestinal fluke. Another example is the Gerson therapy, which attributes all cancer to a deficiency in pancreatic enzymes.)
- Supported through myth and legend: if idea has been around so long, must contain some truth. (Traditional Chinese medicine is a prime example of this. Yes, a few of the herbs they use have medicinal value, but that does not mean the whole package is correct. As for the claim that the fact that an idea has been around a long time must mean it contains some truth, consider this: For thousands of years, people thought that the earth was flat and then, after scientists realized that it wasn't, for hundreds of years after that people believed that the sun revolved around the earth. Just because an idea has been accepted a long time does not necessarily mean it is true.)
- Charge opponents with being close-minded. (See The Galileo Gambit, by yours truly.)
- Charge persecution of unorthodox and revolutionary ideas: "They laughed at..." (See The Galileo Gambit again, by yours truly.)
- Appeals to vanity of patients: "think for yourself." (Indeed. What's the matter with you? Are you going to let doctors and so-called "experts" tell you how to think? Well, are you?... That's sarcasm, by the way.)
- Exaggerated or false advertising claims. (Just listen to infomercials and many radio commercials to see this one.)
- Bogus credentials of practitioners (e.g., degrees from unaccredited institutions). (There are too many examples of this to list.)
- Use of secret formulas. (If they won't tell you what's in it, be very suspicious about putting it into your body.)

It never ends
After all this autism/mercury/chelation blogging, what do I hear on the radio five minutes ago as I was typing away on grant reports in my office? Paul Harvey giving a credulous glowing report from parents who claim that chelation therapy "cures" autism!
Arrrrrggghhhhh!
Sorry. I had to take two minutes to vent. Back to work...
(You know, it occurs to me that I probably just revealed what an old fart I'm becoming that I regularly listen to a radio station that broadcasts Paul Harvey's reports...)

Give me that old time skepticism!
After seven editions away, the Skeptics' Circle has come home to its founder's blog, and St. Nate has brought it back to its roots, which, in this case, is a good thing. Consequently, the Ninth Edition of the Skeptics' Circle is filled with great skeptical blogging that would do the Amazing Randi proud. Check it out.
And look for the next edition to appear at Skeptico two weeks from now. Be sure to show Richard some love and send him examples of your best skeptical blogging to rrockley AT pacbell DOT net.

More vaccine blogging
As you can see by scrolling down this page, I posted a rather lengthy article yesterday about anti-vaccination "skepticism" on The Huffington Post. Coincidentally, Skeptico also posted a nice article on the very same day about Mercury in vaccines and chelation therapy. Through this article, I found a rather interesting blog, Autism Diva. It's a lovely counterpoint to most of the stuff on the Internet about autism in that it approaches the subject from a skeptical viewpoint and doesn't push all sorts of unproven altie therapies for autism. There's one post on the blog that gives an idea how much pseudoscientific quackery like chelation therapy for autism can cost the unfortunate parents of autistic children and another nice withering piece about the uselessness of chelation therapy for autism:
Amen.
She also has a nicely snarky piece on the Autism One conference in Chicago (which starts today), which features talks claiming that fermented foods can cure autism and that you can use "vibrational medicine" to treat autism, among other claims. The fact that David Kirby, author of Evidence of Harm, is the keynote speaker probably should tell you all you need to know about this conference. If that's not enough, Mark and David Geier are featured speakers, as is Dr. Andrew Wakefield, the investigator whose study claiming to find a link between MMR and autism was renounced by 10 its other co-authors as not showing any such link. If that doesn't convince you, then look at the list of abstracts. There are a couple of abstracts that look as though they might be legitimate science, but the vast majority do not. There's a whole lot of abstracts on mercury causing autism, treating autism with zinc, lowering your "toxic load" (a favorite altie term), etc.
I'm going to add the Autism Diva to my blogroll this weekend when I do a little spring cleaning of the list this holiday weekend.
Autism Diva believes the whole chelation "cult" appears to be in some kind of trance wherein everyone agrees that chelation cures the kids, any improvement they make is always attributed to chelation. If it is a cultlike atmosphere, ones who don't see improvement will be afraid or too ashamed to speak up and say it isn't working for fear of being marked as apostates. Everyone in the "cult" sees the emperor fully clothed.

Forgot about this one yesterday
Reported in the New York Times, eighty years ago today.
The indictment was issued on May 25, 1925. (Via RPM at Evolgen.) Note that the Scopes Monkey Trial did not begin until July 10. Expect the science blogosphere to erupt around the time the 80th anniversary of the trial this summer. Certainly, I plan on commenting on it.
You'd think that eighty years later this wouldn't still be an issue, but you'd be wrong, unfortunately. Look around at how Kansas or Georgia debate the teaching of evolution, and you'd hardly know that eighty years have passed.
John T. Scopes, young Dayton (Tenn.) high school teacher, tonight stands indicted for having taught the theory of evolution to students attending his science classes in violation of a law passed by the Tennessee Legislature and signed by the Governor on March 21, 1925.

Rubinstein keeps digging, apparently
Via my Sitemeter logs, I've discovered a blogger named Jody, who has carried out an e-mail correspondence with Professor William D Rubinstein, the history professor who wrote a really badly argued article criticizing evolution, chock full of "intelligent design" creationism canards. He's the same Professor Rubinstein that I lambasted, resulting in an invitation to comment by a blogger named J. Bowen, who had written in essence, a defense of Professor Rubinstein and other evolution "skeptics," which was similarly full of intelligent design canards (although Mr. Bowen does deny being a creationist). Mr. Bowen feels I was unfair with him and that I had used a straw man when calling him a creationist. All I can say in reply is: If Mr. Bowen is truly "not a creationist," as he claims, then I hope that readers knowledgeable about ID fallacies will forgive me for my thinking he is, given that he used some classic ID apologist techniques to "debunk" evolution. If he's not a creationist, he certainly knows how to imitate one almost flawlessly.
But I digress. All I really wanted to say in this post was that Jody's account of his e-mail exchange with Rubinstein gave me a chuckle, and I think it will give you one too.
