Lightening of the blog

Blogging will be light (and may actually end up being nonexistent--it all depends on whether I get any time and the quality of the Internet access I have) over the next three days. I have to go to a training conference in Chicago and then come back and be on call on Sunday.

Don't worry, though. You-Know-Who (and I don't mean Valdemort) will make his usual monthly appearance no later than Monday--and maybe even sooner if I happen to get the chance. It wouldn't do to disappoint his fans...

Also, stay tuned. There's a study (not medical this time) that came out this week that could use a bit of deconstruction, but unfortunately I didn't have time to do more than barely get started on doing a proper job of it before having to leave. I hope to take it on early next week, unless some other more interesting topic comes along. (That's the problem with blogging; if you wait too long to post about an incident, you're so far behind all the other bloggers that you might as well not bother...)

The Eighteenth Meeting of the Skeptics' Circle is here

The Eighteenth Meeting of the Skeptics' Circle has been posted at Wolverine Tom's. Go forth and be innoculated against the rampant credulity in the blogosphere!

And then join Nurse Kelly as she hosts the Circle on October 13 at Time To Lean. And, as always, I continue to scour the blogosphere for hosts for the Circle. If you're interested, e-mail me at oracknows@gmail.com. This is what it's all about.

Well, this is an interesting development...

Via Majikthise, I've learned that the Louisiana Attourney General and a senior medical examiner are investigating allegations of euthanasia after Hurricane Katrina. Because, I posted a very skeptical examination of the allegations a couple of weeks ago, I'll be very interested in seeing where this goes and whether the charges are substantiated.

Grand Rounds, Vol. 2, No. 1 (or #53)

Grand Rounds has just entered its second year, and with it has advanced to a new volume. This time, Family Medicine Notes is hosting. Go forth and check out the best of the medical blogosphere.

Hmmm. Only 19. I was hoping for at least 20. I almost counted Madonna's Sex, except honesty demands that I admit that, although I did pick it up in a bookstore and and browse it once, I didn't exactly "read it." I'm sure know what I mean.

Of course, I'll never get to 100, given that I have absolutely no interest in some of these books (like Goosebumps, The New Joy of Gay Sex, or any of the Judy Blume books). Also, some of the books on the list aren't necessarily good. Just because someone has tried to get a book banned doesn't mean it's a good book. On the other hand, I have no idea which of the other books on the list I should check out. So, everyone, you can crash the party too. Which of these books have you read? Which ones should I check out (that is, if I ever manage to get through the pile of unread books that I have lying around)?

Yoda debates Mace Windu over intelligent design

Yoda debates Mace Windu over intelligent design creationism here. A sample of Windu's critique of evolution:

There is no need to look any farther than my beautiful, perfect, shiny head to know that someone intelligent had to have a hand in its design. This kind of cranial prettiness did not come about by accident.

It degenerates from there...

I never realized that the Flying Spaghetti Monster was an activist

Apparently, the Flying Spaghetti Monster is branching out. This time, the Noodly One was spotted at an antiwar rally. The funny thing is that the right wing blogger who posted this to mock anti-war protesters (some of which, I must admit, are pretty flaky and off the wall) seems to be utterly clueless about the significance of His Noodliness. He should feel honored to have encountered a Pastafarian prophet such as this openly proclaiming his message. He even looks as though he might be wearing an FSM T-shirt, but I can't tell for sure, because the sign is covering the image.

One can only hope this prophet heads over to Dover, PA to proclaim the Word at the intelligent design trial there, where fundamentalists are waging a never-ending battle against biology textbooks "laced with Darwinism." The horror.

This sounds just like our dog

A little criticism directed Orac's way

I really have to stop checking Technorati searches on my blog and my Sitemeter referral logs. I really do. If I didn't check them a couple of times a week, then I would probably never come across posts mentioning me that raise my blood pressure like this one (unless, of course, readers alert me to them). Or maybe I should just learn to ignore such posts, rather than responding and risking provoking a blog flame fest. Too bad last night that I was in just the right mood to pay attention to one post in particular that mentioned me and feeling just cranky enough to lay down a little Respectful Insolence about it.

For a blogger who says he works in the pharmaceutical industry and doesn't like Kevin Trudeau (although I would disagree with his qualification of his dislike in which he said that there's "a lot to Kevin Trudeau that's admirable"--I consider Trudeau to be a scam artist), a blogger going by the 'nym Random John sure doesn't seem to understand one of my major recurring points. He starts here:
Posts like this simply make my blood boil. Perhaps I should keep my “buttons on the inside” (i.e. not let other people push my buttons), but I get frustrated when doctors get their priorities all out of whack and misinterpret the results of experiments.
That's two of us who should perhaps keep our "buttons on the inside," but I get frustrated when other bloggers make big, fat straw men out of what I say and then angrily (or happily--or both) tear down said straw men. The post of mine to which he was referring is here. In it I pointed out how easy it is for doctors to delude themselves into believing a treatment works on the basis of anecdotal observations when it may not and why evidence-based medicine as exemplified by well-designed clinical trials can help avoid that trap and allow doctors to confirm or reject early anecdotal observations. John took issue:
Statistics measure population tendencies, and are bad at predicting individual results. I ought to make every doctor on the face of this planet write this on a chalkboard until they say it in their dreams. Maybe it should be a semester course in medical school and biostatistics. A three-hour course required for graduation. Three hours a week of writing this on the board, supervised, and a recorder stuck under their mouths at night for verification. To pass the class, they have to be saying this in their sleep.

Orac seems to take the most extreme example of the alternative-medicine-is-good-and-conventional-medicine-is-bad nutcase (and, the person who fits the description he gives on the page is a nutcase, I’ll give him that), and equate people giving testimonials.
Geez, I wonder what I said that set him off so much.

Uh, no, that's not what I said or meant. My piece on the altie to which you refer was humor that was indeed directed at the most extreme example, but it did not say that anecdotes are without value. What it did say that is relevant is this:
If you accept vague and/or poorly documented anecdotes and testimonials as sufficient evidence that an "alternative" therapy "works," you just might be an altie.
How is that unreasonable? And, yes, John, there are a fair number people like that. I've encountered them on misc.health.alternative. They inspired the piece, to which many old regulars of m.h.a. contributed, whether they knew it or not. Another relevant excerpt:
If you dismiss every well-designed randomized clinical study that failed to show a benefit for an alternative medicine or therapy over placebo control as either not proving that the therapy is ineffective or as having been manipulated by nefarious forces (conventional medicine, the pharmaceutical companies, the government, etc.) to produce a negative result, you may well be an altie.
Hmmm. Note the words. "Vague and/or poorly documented anecdotes and testimonials." "Dismiss every well-designed randomized clinical study." (Emphasis mine.) I was making fun of people who buy vague and/or poorly documented testimonials for their favorite cure du jour while at the same time automatically rejecting well-designed studies either because they were done by the hated conventional medical community or because don't show what they want them to show. But John isn't finished:
Let’s look at this argument then: clinical trials good, testimonials bad. Do you see the bias here? No?
Uh, no, John, it's not "bias" to understand that testimonials are inherently less reliable than clinical trials in identifying which treatments work and which do not and then putting them into their correct place in the hierarchy of medical evidence. It's just good science. And, no, John, I did not say that anecdotes are "bad." I merely pointed out that they are far less likely to be widely applicable than the results of clinical trials. I've explained multiple times why most testimonials don't even meet the minimum standard of medical evidence, and why personal observation alone is prone to many more biases, including selective thinking and confirmation bias. Finally, contrary to John's characterization of what I said, I have not entirely dismissed anecdotal evidence. Actually I have said repeatedly, that such evidence, if better documented than just a testimonial, can be useful to guide further research. Consider, first, what I said about the difference between testimonials and anecdotes:
The other problem with testimonials is that they don't rise even to the lowest level of medical evidence, the anecdotal report. Anecdotal reports in medicine require a careful documentation of symptoms, lab tests, diagnoses, exact courses of treatment, and a patient's response to treatment. Testimonials almost never present these elements in sufficient detail to judge whether the treatment actually did anything. There's just no way of telling truth from exaggeration or fiction.
I reiterated the faults of testimonial-based "claims" here:
So what's wrong with testimonials? Well, as I like to say, the plural of "anecdote" is not "data," and testimonials usually don't even rise to the level of anecdotes. Testimonials are often highly subjective, and, of course, practitioners can and do pick which testimonials they present. Even in the case of cancer "cure rates," testimonials often mean little because they are given for diseases that surgery alone "cured." (Also, dead patients don't provide good testimonials.) Worse, testimonial-based practice tends to preclude the detailed observation and long-term followup necessary to identify which patients benefit from treatments and which do not, complication types and rates, or long-term results of the treatment. Anecdotes are really good for only one thing, and that's developing hypotheses to test with basic scientific experimentation and then clinical trials.
Note the last sentence. That's me pointing out the proper weight that should be given to anecdotal evidence, which is not zero but is much less than the weight that should be given to a well-designed clinical trial. I suspect the problem here is that John seems to be equating testimonials and anecdotal data. Given that John works for the pharmaceutical industry, I would have thought that he would know the difference (namely that testimonials are usually poorly documented or not at all and are usually primarily intended to sell a product), but apparently not. In any case, what I said was not all that different from what John himself said, except for my emphasis on distinguishing dubious, highly subjective testimonials from the more objectively observed medical anecdote:
The sparks for ideas that lead into scientific revolutions come from odd, anecdotal observations that are outside of what statistics predicts. Individuals give important information that statistics will miss, and cutting out anecdotal or testimonial information and relying solely on clinical trials for our research is like cutting off our legs because the car gets us there faster.
John's also constructing and attacking another huge straw man here. I never advocated "cutting out" anecdotal information (although I definitely do advocate cutting out testimonials, for the reasons I described in detail here, here, and here). I merely pointed out that anecdotes are usually pretty weak evidence. John did have a point in mentioning that clinical trials may not adequately predict the response of any single individual to treatment. That does not invalidate my point, however, because anecdotes are considerably worse than clinical trials at such prediction. In addition, it isn't more anecdotes that will help us predict more accurately the response of any individual to any given therapy. It will be clinical trials that identify factors that might help us predict which individual patients will respond better to which treatment. Indeed, that's the whole point of genomic medicine and molecularly targeted therapeutics like Herceptin.

Now that I think about it, it's rather tempting to build up a straw man of my very own and take John to task for recommending that we abandon clinical trials as medical evidence in favor of anecdotes and testimonials. (Insert much triumphant ranting and raving about said straw man here.)

If I were to do so, though, I just hope it would be a real straw man and not the truth.

Last call for submissions to the Skeptics' Circle

The Eighteenth Meeting of the Skeptics' Circle will convene on Thursday. You still have a day to get your best skeptical blogging to Wolverine Tom. So let's see 'em!

Answering some lurker comments

I was amazed and gratified to the response to my post last Thursday asking for lurkers to delurk temporarily and make a comment, 81 comments thus far and counting, most complimentary. If I'm not careful, I might get a swelled head at the praise. Of course, I realize that, should that ever happen, you (and my fellow bloggers) will be there to slap me down and teach me humility again. There were too many comments for me to answer them all individually, but there were a few that caught my eye.

For example, fasta benj said:
Delurking: medical editor (f, 40) in the UK - read for pieces on critical thinking (alt med, Holocaust denial, ID, ...). So much for the 'medical' part; the 'editor' part suggests that you condense your writing somewhat, And, sorry, but cut the Hitler Zombie.

Blake's 7: first series, or second series?
The "editor" part is correct. I realize that I tend to be more verbose than I should be. Suffice it to say it's probably my biggest weakness, as far as writing goes, and I continue to work on it. As for cutting the Hitler zombie, well, let's just say that, although he has been lying low recently, he may be making an appearance in the near future, having clearly chomped the brain of an old nemesis. Sorry. As for Blakes 7, I'm really not sure which series Orac was in. I thought Orac showed up in the last episode of the first season and stayed until the end.

Next, a reader by the 'nym of Sastra says:
Since you asked: given your expertise, I suppose I'd like to see you post more on "alternative" medicine...Over time, though, I think I've slowly started to develop a bit of a crush on Eneman. This is not good. He seems like a nice, friendly, well-traveled guy with a lot of hobbies and interests, good with kids, happy disposition -- but I have an uncomfortable suspicion that he might be a bit "kinky," so to speak.
Hmmm. I'm not sure how to respond to this one. I wouldn't want to be responsible for such a development. EneMan might be happy and cheerful, but he does have a bit of a creepy edge to him, which is why I find his hanging out with children a bit disconcerting. I'd recommend staying away from EneMan. There are others who are interested in him that way...

Next, we have a comment from "anonymous":
Hi Orac - I read you almost every day. I work for Big Pharma in the NJ/NY/Conn area (where else would big pharma be?) My job responsibility is Market research for Oncology drugs and services. So, while I find all the other stuff riveting, it is your insight into cancer treatment that I find most useful.
Uh-0h. Don't tell the alties that. They already think I'm a pharma shill as it is.

Finally, Kristjan Wager, who has contributed as a guest blogger, comments on something another anonymous poster said regarding my posts on the thimerosal/autism activists:
Someone anonymous asked:

"I've never seen so much sheer anger in a blog dialogue. Does this happen when you mention any other diseases?"

I haven't seen it here at Orac's place , but I have seen quite a lot of anger when someone's favorite alternaitve cancer cure has been debunked. However, with the autism debate, it's often peoples' children we are talking about, which makes the anger more prevalent.
Indeed. I've seen this anger before extensively on misc.health.alternative. It's not just autism, although Kristjan has a point that because it autism affects children it tends to provoke more intense reactions. Oddly enough, I've had tirades almost as intense directed at me for referring to dentists who remove people's fillings for exaggerated fear of mercury as quacks or for pointing out that the evidence does not support the claims of activists that breast implants cause systemic diseases like fibromyalgia or autoimmune diseases. (I can't believe nine months have gone by and I haven't blogged on this topic; I'll put it on the list of future posts.) The problem is magical thinking and desperation, and anything that goes against that thinking is viewed as a threat.

Now, for the moment, I close the mailbag. I liked this whole delurking thing. I hope that some of the lurkers who revealed themselves will comment more often in the future.

This is what I'm talking about

I've mentioned Mothering.com before as a source of antivaccine nuttery and in the context of interviewing Christine Maggiore, the HIV/AIDS denialist whose adherence to altie beliefs appears to have cost the life of her child. Now, via the Final Church of the Nodding Apocalypse, I've found a photo that sums up the altie madness that this magazine was advocating four years ago:


This magazine also fully buys into antivaccine rhetoric, mercury/autism hysteria, and antiamalgam wingnuttery. Remember this whenever an altie cites anything written in this magazine, which appears to be a dubious amalgamation of the worst of altie excesses.

It's a RINO stampede!

The RINOs are stampeding over at Tinkery Tonk. Stay out of the way...

Banned Books Week

I didn't realize it, but I just found out that it's Banned Books Week. Go out and buy or read a book that people have tried to ban!

You can start here.

I still can't believe that the Harry Potter series, Madame L'Engle's A Wrinkle in Time, and Daniel Keyes' Flowers for Algernon (among many other rather hard-to-believe candidates for banning) have kept ending up on this list over the last 15 years.

Maybe I wasn't as on top of this as I had thought

Last week, I wrote about a couple of Letters to Nature in which scientists discussed in a tongue-in-cheek manner what the genetics of inheritance of the wizarding ability might be in the Harry Potter stories. A reader named Sarah has pointed out to me that I (and the authors of both Nature letters) are a bit behind the times. Apparently, this discussion has been going on for at least since 2003, and Sara shared with me some links to prove it. I thought I'd share them with you:


Ah, well. I guess that's what I get for being a relative newcomer to the Harry Potter phenomenon, having only just read all the books since last winter.

Another tragically unnecessary death of a child

A few weeks ago, I commented extensively on the case of Abubakar Tariq Nadama, a five year old autistic child who died of a cardiac arrest while receiving an unproven "alternative" treatment (chelation therapy) for his autism. Now I've been made aware of another case just as tragic, a case also sadly resulting in the preventable and unnecessary death of a young child:
The HIV-positive mother of two laid out matter-of-factly why, even while pregnant, she hadn't taken HIV medications, and why she had never tested her children for the virus.

"Our children have excellent records of health," Maggiore said on the Air America program when asked about 7-year-old Charlie and 3-year-old Eliza Jane Scovill. "They've never had respiratory problems, flus, intractable colds, ear infections, nothing. So, our choices, however radical they may seem, are extremely well-founded."

Seven weeks later, Eliza Jane was dead.

The cause, according to a Sept. 15 report by the Los Angeles County coroner, was AIDS-related pneumonia.

These days, given advances in HIV care, it's highly unusual for any young child to die of AIDS. What makes Eliza Jane's death even more striking is that her mother is a high-profile, charismatic leader in a movement that challenges the basic medical understanding and treatment of acquired immune deficiency syndrome.
Christine Maggiore is a high profile spokesperson for a movement that refuses to accept the now well-established science that concludes that HIV causes AIDS. She is the author of a book entitled What If Everything You Thought You Knew About AIDS Was Wrong?, has appeared on The Ricki Lake Show and 20/20, and has been interviewed for Mothering and Newsweek magazines about her activism for the contention that HIV does not cause AIDS. (Mothering, by the way, is the same magazine where the web discussion forums are filled with anti-vaccination rhetoric.) This phenomenon of HIV/AIDS denialism is disturbing to scientists and mainstream AIDS organizations for good reason:
Mainstream AIDS organizations, medical experts and ethicists, long confounded and distressed by this small but outspoken dissident movement, say Eliza Jane's death crystallizes their fears. The dissenters' message, they say, is not just wrong, it's deadly.

"This was a preventable death," said Dr. James Oleske, a New Jersey physician who never examined Eliza Jane but has treated hundreds of HIV-positive children. "I can tell you without any doubt that, at the outset of her illness, if she was appropriately evaluated, she would have been appropriately treated. She would not have died.

"You can't write a more sad and tragic story," Oleske said.
Well, actually, you can. The story of Abubakar Nadama, for instance. Both stories are as sad and tragic as can be imagined, and in similar ways.

I've encountered HIV/AIDS denialists before, not surprisingly, on misc.health.alternative. They tend to be influenced by the opinions scientists such as Peter Duesberg and Harvey Bialy, both of whom are proof positive of the way in which even f0rmerly reputable scientists can fall under the sway of pseudoscience. Based on their writings and those of others, HIV denialists claim that it is drugs like AZT used to treat AIDS that destroy the immune system, not HIV. Of course, when it is pointed out to them that AIDS was identified as a syndrome in the early 1980's and AZT wasn't widely used until 1987, they wave their hands and blame AIDS on "lifestyle" and "recreational drugs" (exacerbated by anti-HIV drugs, of course), which to me sound a lot like the unnamed "toxins" to which alties like to attribute many diseases. HIV denialists also ask questions like: Why do the in vivo and in vitro virus neutralizing antibodies that are present in easily assayable amounts in the blood of HIV infected people not protect against AIDS if HIV is the culprit? (Even I, a surgeon, can answer that one without having to look up any references: There are lots of diseases that provoke a neutralizing antibody response that doesn't fully protect against disease. Hepatitis B, for example. If the antibody response protected against disease, then the organism wouldn't be pathogenic.) They also like to claim that we don't know very much about how HIV does all the things to the immune system that it does, when in fact we know quite a bit about how HIV accomplishes its devastation of the immune system. In any case, the evidence that HIV causes AIDS is overwhelming, and the success of antiretroviral cocktails in decreasing death rates from AIDS and producing many actual long term survivors of a disease (AIDS) that used to be 100% fatal within a relatively short period of time flows from the scientific validity of the HIV/AIDS hypothesis.

The HIV/AIDS denialists, like alternative medicine cranks in many other diseases, cherry pick studies and ignore the vast quantity of evidence that doesn't support their point of view. They magnify anything we don't understand about HIV or any inconsistency in existing data and conveniently forget about the enormous amount that we do know about how HIV causes AIDS. They absolve themselves from having to come up with a compelling alternate hypothesis and the evidence to support it. And, of course, they postulate dark conspiracies of pharmaceutical companies wanting to "suppress" alternative "cures" and sell high-priced drugs. They also tend to be to be antivaccine, as many mercury/autism activists are and Ms. Maggliore was:
What set Maggiore apart became clear only when she talked about her views on medicine.

She didn't vaccinate either child, believing the shots did more harm than good. She rejected AZT and other anti-AIDS medications as toxic. "I see no evidence that compels me that I should have exposed a developing fetus to drugs that would harm them," she said.

Maggiore hired a midwife and gave birth to her children at home; Charlie was born in an inflatable pool on her living room floor. She wanted to avoid being tested for HIV or pressured to use AZT in a hospital, although technically neither is required by California law.

She breast-fed both children, although research indicates that it increases the risk of transmission by up to 15%.
AZT and other anti-retrovirus drugs can decrease the risk of maternal-child transmission to very low levels and is responsible for the plummeting rate of cases of AIDS among children; for an HIV-positive mother to refuse to use it is tantamount to child abuse (no matter how well-meaning she is or how much she loves her child) and exposes the deficiencies in the child welfare system. And right in the thick of this story is an old friend, with whom Orac has tussled before over his posts to the Huffington Post: Dr. Jay Gordon, who apparently was one of the doctors who treated Eliza Jane:
Dr. Jay Gordon, a Santa Monica pediatrician who had treated Eliza Jane since she was a year old, said he should have demanded that she be tested for human immunodeficiency virus when, 11 days before she died, Maggiore brought her in with an apparent ear infection.

"It's possible that the whole situation could have been changed if one of the doctors involved — one of the three doctors involved — had intervened," said Gordon, who himself acknowledges that HIV causes AIDS. "It's hindsight, Monday-morning quarterbacking, whatever you want to call it. Do I think I'm blameless in this? No, I'm not blameless."
No, Dr. Gordon is not blameless. Although I believe that Dr. Gordon probably means well and probably does more or less accept that HIV causes AIDS, I hope he'll excuse me if I can't help but thinking that he sounds a bit like he is covering his behind. It is some of the stuff I've found on his own website that leads me to wonder about whether he truly accepts the science behind the HIV/AIDS hypothesis. For example, look at Dr. Gordon's preamble to a bunch of recommendations for unproven "remedies" to alleviate HIV/AIDS symptoms, such as echinacea to "strengthen the immune system" and milk thistle to "cleanse" the liver:
The conventionally and most widely held approach say that AIDS is caused by the HIV (Human Immunodeficiency Virus) which is a very difficult virus to kill or control.

There is a second school of thought not terribly popular with physicians: HIV causes AIDS with, because of, or assisted by the medication used to prevent AIDS. The usual anti-HIV medication is quite potent and works in ways beyond the scope of this article. Suffice it to say that the medications have huge side effects and that the latest research published in late-April makes it quite clear that our hope that the antiviral compounds actually cure AIDS is probably incorrect and the virus is very capable of surviving this chemical onslaught and "hiding" for many decades in the human body. Please do not misunderstand, as far as I can tell, many lives have been prolonged, changed for the better and even saved by advances in AIDS chemotherapeutics. I just think it's also very reasonable and prudent to investigate other ways of keeping this virus in check by strengthening the immune system's ability to deal with it and by increasing the overall health of the person who is carrying HIV.
Is it just me, or does it sound as though Dr. Gordon is rather sympathetic to the AIDS denialist position and somewhat grudging in his acceptance of the HIV/AIDS hypothesis? If, as Dr. Gordon says, he accepts the current science that HIV causes AIDS, then why does he present the the view that HIV causes AIDS "with, because of, or assisted by the medication used to prevent AIDS" on his website in such a context that leads the reader to believe that he considers the denialist view as almost equally plausible to what he terms the "conventionally" held view that HIV causes AIDs. Why is his disclaimer so weak? Why, also, did he not seem to consider the possibility that the "ear infection" that he suspected in Eliza Jane might be something more serious, given that he knew that she was the child of an HIV-positive mother who had flouted every medical guideline for preventing HIV transmission to her children, even having breast fed them? Why did he not insist on an HIV test? Even I would have known to suspect AIDS, and I'm just a dumb surgeon. No doubt Ms. Maggliore would have refused, but at least he would have started to do the right thing.

I am quite sure that Mrs. Maggliore is suffering enormous emotional pain because her daughter died. I also have no doubt that she loved her daughter as only a mother can, despite her rationalizations about the cause of her daughter's death. However, we must not allow our sympathy for her grief to lead us to forget that her daughter is dead because she enthusiastically bought into a bogus, pseudoscientific line of altie nonsense--or that she still buys the line and is aggressively selling it on the radio and elsewhere. It is indeed unfortunate that this horrific experience didn't lead her to wonder if maybe--just maybe--conventional science is right about HIV causing AIDS after all.

Unfortunately, all too many others buy into HIV/AIDS denialism too, which guarantees that Eliza Jane will not be the last child to be infected with unnecessarily with HIV via maternal transmission or to die from that infection.

ADDENDUM: Mossback Culture has more on this here and here,particularly on the role of prominent bloggers in facilitating HIV/AIDS denialism. (And, boy, is he pissed, so much so that he does something I wish he hadn't done and takes a cheap shot at his intended target in the last paragraph of this post.) His main target is one blogger in particular that I rather used to like--until I was made aware of his decidedly unskeptical (or, as I like to call such crankery, "pseudoskeptical") HIV/AIDS denialist opinions last spring (opinions that I would have been aware of sooner had I read his blog more often).

More can also be found, ironically enough, at the Huffington Post, where Trey Ellis comments. Other medical bloggers Red State Moron and Gordon's Notes have also commented.

Thirty three years too late...

Given that Bowie is probably my favorite performer of all time, I find this reassuring...


david bowie
You're David Bowie...and every guy wants to be you, every girls wants to be in your pants. Or vice versa, or both! You are innovative, always weird, and aesthetically pleasing. Your lyrics are literate, and your music is unlike any other. You are always unique, no matter what situation you are in. Everyone tries to bite off your style, but no one can be you because you are funky fresh. Be careful to keep your mental health in check, because you have a tendency to flip out. But hey, being borderline crazy makes you even more alluring! You are skilled at manipulating everyone: the press, your fans, and even your closest friends. You are beautiful and strange, and you allow yourself to change and grow.


Because I have a soft spot for glam (among my other musical proclivities, both odd and mainstream), I thought this would be a good jumping off point for me to list a few of my favorite 1970's glam rock albums:
  1. David Bowie, The Rise and Fall of Ziggy Stardust and the Spiders from Mars
  2. David Bowie, Hunky Dory
  3. Mott the Hoople, All the Young Dudes
  4. David Bowie, Aladdin Sane
  5. T. Rex, Electric Warrior
  6. Queen, A Night at the Opera
  7. Alice Cooper, Billion Dollar Babies (Alice was glam, albeit its darker side.)
  8. Sweet, Desolation Boulevard
  9. Elton John, Goodbye Yellow Brick Road (Oh, yes, Elton was glam in his
