Whooping cough–back again
Jun/27/10 23:24
Last week, the California Department of Public Health made this announcement:
WHOOPING COUGH EPIDEMIC MAY BE WORST IN 50 YEARS
Date: 6/23/2010
Number: 10-041

SACRAMENTO
Urging Californians to get vaccinated now, Dr. Mark Horton, director of the California Department of Public Health (CDPH), warned today that the state is on pace to suffer the most illnesses and deaths due to pertussis, also known as whooping cough, in 50 years.
“Whooping cough is now an epidemic in California,” Horton said. “Children should be vaccinated against the disease and parents, family members and caregivers of infants need a booster shot.”
As of June 15, California had recorded 910 cases of pertussis, a four-fold increase from the same period last year when 219 cases were recorded. Five infants — all under three months of age — have died from the disease this year. In addition, 600 more possible cases of pertussis are being investigated by local health departments.
Pertussis is cyclical. Cases tend to peak every two to five years. In 2005, California recorded 3,182 cases and eight deaths.
Pertussis is a highly contagious disease. Unimmunized or incompletely immunized young infants are particularly vulnerable. Since 1998, more than 80 percent of the infants in California who have died from pertussis have been Hispanic.
The pertussis vaccine is safe for children and adults. Pertussis vaccination begins at two months of age, but young infants are not adequately protected until the initial series of three shots is complete at 6 months of age. The series of shots that most children receive wears off by the time they finish middle school. Neither vaccination nor illness from pertussis provides lifetime immunity.
Pregnant women may be vaccinated against pertussis before pregnancy, during pregnancy or after giving birth. Fathers may be vaccinated at any time, but preferably before the birth of their baby. CDPH encourages birthing hospitals to implement policies to vaccinate new mothers and fathers before sending newborns home. CDPH is providing vaccine free of charge to hospitals.
Others who may have contact with infants, including family members, healthcare workers, and childcare workers, should also be vaccinated. Individuals should contact their regular health care provider or local health department to inquire about pertussis vaccination.
A typical case of pertussis in children and adults starts with a cough and runny nose for one-to-two weeks, followed by weeks to months of rapid coughing fits that sometimes end with a whooping sound. Fever is rare. Read More...

I’ve been off-line for awhile, attending to some other issues in life. However, it’s time for a celebration about the anti-vaccination crowd, including Jenny McCarthy. The US Vaccine Court has ruled that there is no scientific evidence linking vaccinations to autism. To quote ruling:
Petitioners' theory of vaccine-related causation is scientifically unsupportable. In the absence of a sound medical theory causally connecting William's received vaccines to his autistic condition, the undersigned cannot find the proposed sequence of cause and effect to be logical or temporally appropriate. Having failed to satisfy their burden of proof under the articulated legal standard, petitioners cannot prevail on their claim of vaccine-related causation. Read More...

Book review–Don't Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health
Dec/04/09 10:16
I just finished reading Don't Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health (ISBN:031253387X, 2009) written by Aaron Carroll MD and Rachel Vreeman MD, both pediatricians and researchers at the University of Indiana School of Medicine.
First of all, the book is an amusing, easy read, using terms like “snot” and “poo” to describe bodily secretions. At some 200 pages, it was a quick read, not requiring a lot of time. Obviously, the book was written for a wide audience, debunking many pseudoscientific myths about health. For those of us who demand supporting research, it has a vast list of primary and secondary research citations for further reading. In fact, for me, those citations are going to be invaluable in future articles.
The book goes about debunking silly myths such as “don’t swallow your gum because it will get stuck in your intestine for 5 (10, 20, whatever) years” or the old “five second rule” which we all suspected wasn’t wise. There was one chapter on “double dipping”, which was popularized on a Seinfeld episode many years ago, in which the authors discussed research that showed that double dipping does in fact transfer a lot of germs from the chip to the dip. Not that I would confess to being a double dipper, but I may not be a single-dipper at a party after reading this book! Read More...

Science, lies, and stolen emails

As this is a blog about medicine, I haven’t written much about global warming. Moreover, until a few months ago, I was a bit of a skeptic about the science behind global warming. My skepticism was centered on a few key points that I didn’t feel had been adequately addressed:
Of course, my feelings on global warming would demolish my bona fides to be skeptical about alternative medicine and other pseudoscience. However, I thought the true global warming deniers (and even more so, those who deny the human cause of global warming) were true pseudoscientists, so I decided to study it myself, learning as much as I could about the subject. As I did, my skepticism faded. I found out that the Medieval Warm Period wasn’t as warm as I presumed, and that there is little global evidence that it was actually warmer then compared to today. In fact, regional differences in temperature can be large. I guess it goes back to correlation vs. causation. I was being pseudoscientific in my early thinking about global warming.
Actually, my discomfort with the much of what I was hearing from global warming deniers was similar to what I read from the anti-vaccination crowd. Each of the climate change denier’s pseudoscience is easily debunked. Read More...
- First, I was unconvinced that current temperatures exceeded that of the Medieval Warm Period, a period of warm climate in the North Atlantic from about 800 to 1300. During this time, the weather was warm enough for the Vikings to colonize Greenland and to support a settlement in Newfoundland.
- Second, California glaciers (yes California has numerous glaciers), like Palisade Glaciers in the Sierra Nevada mountain ranges were only about 700 years old, so obviously (to me), it’s colder today than it was before these glaciers formed.
- Third, the earth is just so complicated, it might take hundreds if not thousands of years of data to see any real trends.

How pseudoscience makes its case, Part 3
Nov/19/09 09:12
This is part of my ongoing discussion on how quacks use pseudoscience to push their myths and potions on the world. Part 1 discussed the scientific method, which allows us to objectively analyze the natural world. Part 2 discussed the best way for us to examine the difference between science and pseudoscience.
I just read an outstanding analysis, by Steven Novella, MD, a clinical neurologist at Yale University, of how pseudoscience (those who pretend to praise the scientific method, yet do it in a way that is not actually science) and anti-science (those who repudiate science outright, or even undermine science, with subjective analysis and untestable spirituality) to reject evidence-based medicine.
Dr. Novella clearly states how science in medicine works:

Dr. Novella clearly states how science in medicine works:
This leads us to the final continuum – the consensus of expert opinion based upon systematic reviews can either result in a solid and confident unanimous opinion, a reliable opinion with serious minority objections, a genuine controversy with no objective resolution, or simply the conclusion that we currently lack sufficient evidence and do not know the answer. It can also lead, of course, to a solid consensus of expert opinion combined with a fake controversy manufactured by a group driven by ideology or greed and not science. The tobacco industry’s campaign of doubt against the conclusion that smoking is a risk factor for lung cancer is one example.The anti-vaccine movement’s fear-mongering about vaccines and autism is another.

Bill Maher is a science denialist
Nov/17/09 08:36
Bill Maher, a rather liberal talk show host, has recently been joining the anti-vaccination crowd, adding his voice to the Hollywood centered vaccination denialists. He is a typical science denialist, ignoring the vast wealth of science, research and publications, to make statements, in this case about promoting pseudoscience in his dismissal of the value of vaccines. Moreover, Mr. Maher spends time denying he is a denialist, which usually is an indicator that one is a denialist.
Interestingly, Maher is usually in sync with my feelings about global warming and evolution denialists, who use pseudoscience and outright denial to "prove" that there is no global warming or evolution. Usually, skeptics or anti-denialists (one day we need to get this terminology right) are consistent, we dismiss pseudoscience outright. I have no clue why he has chosen this particular pseudoscience and quackery to support, but maybe he just thinks Jenny McCarthy knows more than real scientists. Read More...

Debunking 2012 myths
Nov/12/09 23:59
There's a new movie coming to a theatre near you tomorrow, which purports to show us how the world is going to come to an end. The movie, 2012, looks like a typical blockbuster, heavy on special effects. Now, many of us understand that movies are, well, fantasies, even when based on real events. This movie is a fantasy based on myths.
NASA, an organization filled with really smart scientists, has published a FAQ that debunks a couple of the myths that 2012 will mark the end of the world. NASA will do a much better job about demolishing the pseudoscience than I will, but the two key issues are:

- A rogue planet or some other object, called Nibiru, will collide with the earth and destroy us. There are no objects during the next few years that will destroy the earth. Of course, it has happened in the past, destroying the non-avian dinosaurs, and will probably happen in the future.
- The Mayan Calendar long period calendar ends in 2012. Of course, all calendars end, then restart with a new year.
Debunking H1N1 Vaccine Myths
Nov/05/09 10:06
The internet is a wonderful place for getting information. But it's also a disaster in finding good information. The problem is that if you read medical facts on the internet, you tend to give equal value to both scientifically supported and outright pseudoscientific statements. I read a few posts on Facebook, which seems to be the modern world's gossip center, that spouted all sorts of conspiracy theories and ridiculous myths about the H1N1 Vaccine. Read More...
How pseudoscience makes its case, Part 2
Nov/04/09 16:30
A few days ago, I discussed how science works. It's not a belief. It's not a random set of rules. It is a rational and logical process to determine cause and effect in the natural world. Pseudoscience, by its very nature, ignores the scientific process; instead, it pretends to come to conclusions through science, although it does not.
Again, be very wary if you hear someone say, "it's proven." I've heard those words from both alternative medicine pushers and from well-trained physicians. I have previously discussed the ineffectiveness of almost every alternative medicine therapy. But what about your physician? They are, by far, devoted to your health and well-being. But they cannot know everything about medicine (thus, why we have specialists), so they may repeat information that is not valid. Read More...

Fox News and the flu vaccine
Nov/02/09 11:23

How pseudoscience makes its case, Part 1
Nov/02/09 09:38
I always get suspicious when someone makes an argument with the statement of "it's been proven to work", "the link is proven", or, alternatively, they state the negative. Typically, I hear these kinds of statements from the pseudoscience pushing group. Many of us have debunked the "there is a proven link between vaccines and autism." Or that any number of alternative medicine (CAM) therapies don't actually work. In fact, science rarely uses the term "proven", because the scientific method is not a system to make a definitive answer on any question–scientists always leave open the possibility of an alternative hypothesis that can be tested. If the alternate hypothesis can be supported through experimentation, then it can replace the original one. When an alternative medicine or junk science supporter states "it has been proven" then you can be assured that conclusion is unsupported by scientific research. Read More...
Swine flu remedies
Sep/20/09 23:47
Sometimes, I just read the most awful pseudoscience with respect to swine flu, or the H1N1 flu variant. I had to read this woo over at Daily Kos, a liberal blog site. Let's review the authors "claims":
- Get sleep. OK, this is probably a good piece of advice for anyone. But there is no evidence whatsoever that sleep has any influence on subsceptiblity to infections. However, I won't be too critical of this advice, because sufficient sleep is important.
- Eat right. Once again, good advice. The author mentions shiitake mushrooms, but the evidence is only in animal models, and even there, the in vivo results required an unorthodox method to detect a change. The author mentions zinc, the effect of which has already been discredited. The rest of the claims are similar. No real research supporting it, or actually showing it doesn't work.
- Stay hydrated. Once again, good advice. But it's not going to do anything to prevent you from getting the flu.
- Exercise. The author makes two specious and unsupported claims. First, a little exercise strengthens your immunity, but, second, too much exercise makes you more subsceptible. Well, there's some evidence that aerobic exercise does improve immunity to certain infections. But it doesn't say anything about "too much." Of course, I would contend a healthy cardiovascular system through vigorous aerobic exercise would be worth the risk of a flu.
- Some woo about foods to eat if you do get the flu. None of it works. The flu will take its course, so it's important not to infect others, and if there are serious secondary infections, the patient should seek treatment.
Immunization–get the facts
Aug/09/09 14:17
Just when I thought that the whole anti-vaccination movement was going to be eclipsed by the whole healthcare reform debate (or myth-pushing, depending on your point of view), I still realize that there are groups who think that vaccines are not usesful. People are starting to stand up to the pseudoscience-based woo-pushing crowd: Read More...
Tom Harkin's wants to waste money on healthcare
Jul/03/09 10:59
Tom Harkin, Democratic Senator from Iowa, and one of the leading supporters of quack medicine is at it again. As the US Senator who forced the junk science NCCAM onto the National Institutes of Health and has drained precious scientific research dollars, he is now putting his pseudoscientific ideas into health care reform. As a member of the Senate’s Health, Education, Labor and Pensions Committee (HELP), he is trying to be sneaky, because he has the power to do so. He has been instrumental in attaching some amendments to the Affordable Health Choices Act (the formal name for the bill in Congress to reform healthcare policy), including:
I have no issue with the first two, especially since the cost of medical education is so large that some deferment is appropriate. I might add that other health care students (pharmacy, nursing, and other technical specialties in medicine) should receive a similar consideration. Read More...
- A provision to allow medical students to defer loan repayment until they finish their residencies
- Limits on the types of expenses medical students cover with loan funds
- An provision to promote and fund research on pain management
- Inclusion of alternative medicine workers in the bill's definition of "healthcare workforce"

Zicam, Part II

Homeopathic product recall
Jun/16/09 20:04
Today, the US FDA warned consumers to immediately stop using the product Zicam, a homeopathic remedy, because it may cause anosmia, the loss of sense of smell. The FDA has received over 130 adverse reports from consumers who believe that they suffered anosmia after using Zicam.
Zicam is marketed a Big Herba company, Matrixx Initiatives, Inc., and is sold as a remedy for relief of symptoms of colds, flu, and allergies (all with different causes). There is little or no evidence from respected peer reviewed journals that zinc gluconate, the active ingredient in Zicam, has any effect on the course, duration, or severity of common upper respiratory tract infections. The Cochrane Reviews state that, the “evidence of the effects of zinc lozenges for treating the common cold is inconclusive.” Infectious disease researchers from Stanford University have concluded that most positive studies of zinc gluconate are flawed in design and that the “therapeutic effectiveness of zinc lozenges has yet to be established.” A well designed double-blind study published in Clinical Infectious Diseases concludes that the “data do not support a role for intranasal zinc gluconate for prevention or treatment of the common cold.” Read More...

Big Herba
Jun/11/09 15:03
One of the strawman arguments I constantly hear is that Big Pharma (the pejorative term used by woo-meisters to describe ethical pharmaceutical companies) block natural therapies because they will lose profits. My argument has always been that if these “therapies” actually worked, Big Pharma would find a way to patent them, bring them to market and make more profits. Well, at least that’s what I thought.

Alternative medicine–waste of money
Jun/11/09 10:31
As I’ve discussed before, Complementary and Alternative Medicine (CAM) are so-called treatments that lack any scientific or medical support. The National Center for Complementary and Alternative Medicine (NCCAM), which was funded by the US Congress to be a part of the National Institutes of Health, continues to discover that these treatments do not work. And it wasted $2.5 billion to discover that they don’t work. I would have done it for $1.5 billion. In fact, given that most of the CAM therapies rely upon ideas that have no foundation in physics, chemistry, biology, physiology or any other science, most of the studies shouldn’t have been done at all.

The Jenny McCarthy Song
May/15/09 09:22
Without making excuses, I really try to keep this blog focused on issues that might impact the medical business world. I am, however, strongly offended by pseudoscience, the primary “authority” for most quack remedies, alternative medicine, and the anti-vaccine movement. I have previously discussed Ms. McCarthy a number of times, and without a doubt, I believe she’s a danger to healthcare. The consequences of the anti-vaccination push is evident by real science.

Harold Varmus interviewed on C-span
May/11/09 07:59
Yesterday morning, I was listening to Harold Varmus being interviewed live (interspersed with listener calls) on C-SPAN Radio. For those of you unfamiliar with Dr. Varmus, he is currently the co-chair of the President's Council of Advisors on Science and Technology, CEO of Memorial Sloan-Kettering Cancer Center, former Director of the National Institutes of Health (NIH), and a recipient of the Nobel Prize in Physiology or Medicine in 1989. In other words, Dr. Varmus has all of the credentials of a scientists, if not one of the great scientists of our era.
I have been unable to find a transcript of the program, but a couple of points from the interview were particularly memorable to me. First, he made a full-throated support of vaccination of children, and made a diplomatic criticism of the anti-vaccination movement. The second point that stuck with me followed a call from an individual who had one of those “my friend was dying of this, and they went to this website and was cured of that” stories. In this case, the caller said a “friend” of hers was suffering from diabetes (not sure how bad or what type), and her friend went to some website (I was driving, so I didn’t have a chance to write it down) that told her to switch from a high carbohydrate diet to one with lots of proteins and fresh vegetables. Only this diet would “cure” the diabetes. Of course, my thought when I heard this story was, “well, switching to a low carb diet may have been the reason.” Read More...

Swine flu–don't panic
Apr/30/09 00:02
With respect to the swine flu, I want to repeat myself, once again–Don’t Panic.
Yes, the World Health Organization revised the pandemic alert for swine flu from 4 to 5. They did this to urge vaccine manufacturers to prepare a new vaccine, to warn governments to prepare in advance, and to request that government surveillance be heightened.
This does not mean that we will be returning to the Spanish Flu epidemic of 1918, where more than 20 million people died worldwide. We are healthier, there are no major wars such as World War I, we have a better healthcare system, we have more focus from governments, and we have better treatments. Read More...

Swine flu
Apr/29/09 15:34
Well, actually I’m not going to say too much about swine flu, except that my initial impression is that it’s not that much different from other types of flu in terms of severity. For example, during the 2007-2008 flu season, there were 83 pediatric mortalities in the US that resulted from influenza infections. In other words, like a lot of diseases that we think are minor, there are serious health consequences that often fly “under the radar.” There is a certain fascination with this disease because of where it started (Mexico), conspiracy theories, and for other reasons that are beyond my ability to understand. I am personally not concerned, because, as I mentioned above, the morbidity of the infection probably is similar to other types of influenza.
There are a number of bloggers who are passing along sage and sane advice. Basically, don’t panic. Wash your hands. And that’s about it for really good medical information.
Of course, the woo-meisters have weighed in with their useless advice. I won’t even begin to explain the logical and scientific fallacies of colon cleansing, but it isn’t going to either prevent or lessen the severity of swine flu. Read More...

Denialism and pseudoscience
Apr/21/09 14:18
Today, I commented to a blog entry at Beyond the Short Coat, which is one of my daily stops on the medical blogosphere. The author, like a lot of bloggers in the medical arena, has been taking on the world of medical woo, that is, those ideas in medicine that completely lack verifiability and scientific credibility. I have a similar disdain for woo, for essentially the same reasons as the physicians who write in those various blogs. Mostly, they are troubled that patients turn to these useless therapies because they may not be getting adequate medical care, or even that those fake therapies may have terrible consequences for the patient. I take it a step further in that I believe that this woo has a substantial economic consequence with increased costs for patients, providers, and third-party payors. Read More...

I don’t know what happened, but several people I know have accused me of being a skeptic. What is a skeptic? Is that like a psychic? Maybe I got the label because I would roll my eyes and laugh when someone would say, “take these zinc/vitamin C/echinacea tablets to cure your cold.” That statement is usually followed up by, “my mother’s friend’s sister-in-law’s cousin never gets colds after taking these pills.” Read More...
The cost of medical woo
Apr/15/09 22:45
My blog entries wander between three broad topics: medical woo (pseudoscience, science denialism, vaccine denialism, and alternative medicine), market opportunities for medical products and healthcare policy. And one discussion about my beloved Syracuse Orange. My three broad interests in the medical arena are interrelated in such a fashion that medical companies (both pharmaceutical and medical devices) need to prepare strategic plans that maximize their success despite some difficult market forces.
First, let’s talk about the whole area of medical woo. The anti-vaccine movement (which I will continue to label as vaccine denialism), if it continues to gain traction in social consciousness, will require more investment in studies that continue to confirm that there is no link between vaccines and autism (OK, yes the proper scientific method would force me to say that there is a possibility that a link could be found, but after 100’s of clinical papers, I’m firmly on the side that this issue has been decided). If this movement becomes problematic, we might be dealing with infectious disease epidemics unseen in a generation. Can hospitals and clinics deal with these diseases? How large are the infectious disease wards in hospitals? How many infectious disease specialists are there? And what kinds of medical products will need to be available to treat these diseases?

Scientific medicine and Big Pharma
Apr/08/09 08:42
I keep reading across the blogosphere that Big Pharma (for the sake of this discussion, defined as all medical products companies, including ones that don’t manufacture or market pharmaceuticals) somehow blocks either positive or negative results to further their profits. The accusations come from a wide variety of sources, some of the more vocal being the anti-science proponents, such as the anti-vaccination movement. Utilizing an ad hominem argument of personalizing the issues and then attacking the motives or character of others, usually those who dispute the claims made by pseudoscience. Read More...
Jenny says....
Apr/07/09 08:22
If you read my blog, you know I don’t have much respect for the anti-vaccination movement, and I have contempt for Jenny McCarthy, JB Handley, Andrew Wakefield, Generation Rescue and others for the damage they have done to health care. One of my favorite blogs to read is Science Based Medicine, which has several physicians editors (and guest editors) who discuss medicine from a scientific perspective. I share their point-of-view on medicine, and since my background is from the industry perspective, I cannot obviate the need for good scientific reasoning for product development. In Welcome back, my friends, to the show that never ends: The Jenny and Jim antivaccine propaganda tour has begun, David Gorski, MD, tears apart, in about as civil a manner as he can, Jenny’s recent interview.

The anti-Jenny blogosphere

Medical and science blogs are aghast at Jenny McCarthy’s comments that I reviewed earlier today. Let me list some of the more choice comments. Read More...
Jenny McCarthy again!
Apr/02/09 12:35
Why is anyone listening to Jenny McCarthy? She just published a new books continuing her unscientific and unsupported rants about how vaccines cause autism. As of today, there are still no links between the two, but because she was a Playboy Playmate of the Year, she has a soapbox to promote her views. Read More...
The anti-vaccination tragedy
Mar/31/09 10:07
I have written about the anti-vaccination movement several times recently, yet every day, I read another article or another comment somewhere that reminds me of this situation. Today, I came across a recently published article in The Lancet, one of the most respected peer-reviewed medical journals, which reinforced one of the consequences of the anti-vaccination movement. The article, Measles in Europe: an epidemiological assessment, states that there were 12,232 cases of measles in Europe during 2006 and 2007. Most cases were unvaccinated or improperly vaccinated children. Read More...
Vaccines, once again and a bit irreverent
Mar/30/09 22:55
As I’ve discussed previously, I find the anti-vaccine movement, linking cases of autism to pediatric vaccinations, to be based on pseudoscientific principles. There are several individuals that have pushed this quackery, but one of the more visible is Jenny McCarthy, ex-Playboy Playmate of the Year (no, I’m not going to link to it), bad actress, and failed game-show host. I am flabbergasted that anyone would listen to this woman, a scientific illiterate, about anything outside of how to model and possibly how to choose bad movies. That parents are making decisions about vaccinating their children based on her bogus beliefs is beyond my simple understanding of the world.
There are always consequences to every action, and there are many by delaying or refusing vaccinations. The Jenny McCarthy Body Count is a website that lists every vaccine-preventable case and death that has occurred since Jenny made public her belief that vaccines caused autism in her son (which many believe is a misdiagnosis) in June 2007. Since then, there have been 720 preventable cases and 142 preventable deaths (as of today). As the website says, she’s not responsible for everyone one of these cases or deaths. But if she convinces just one person to not adhere to a vaccine schedule for their children, then it’s one too many.

Wikipedia–bad medicine
Mar/16/09 10:25
The internet has become a great tool for researching information from new gadgets to statistical analysis of politics. One of the most popular websites for research is Wikipedia, an online, democratic encyclopedia. As I have discussed previously, I link to it frequently, to give an overview about a particular topic. I admit I go to the website many times a day to get more information on a topic of interest to me, sometimes just for entertainment, and occasionally to laugh at the quality of articles. Wikipedia functions as a democracy, meaning anyone can edit it. Sometimes it appears that the project is more of an anarchy, but there are “police”, called administrators or admins, and several levels of bureaucracy above the police, to control the situation. The admins are elected by the community of editors. They can block editors (kind of a punishment), and as best as I can tell, every single action by anyone is subject to a lot of yelling, screaming, whining, and complaining. Actually, a social scientist might find the whole system quite fascinating, as I do.
A Wikipedia article is almost always the #1 hit when a google search is done on a subject. This might be useful if you are interested in episodes of 24 or need to know all about the Boston Red Sox. In most cases, the quality of the articles are not a life and death issue. If a Yankees fan chooses to vandalize (yes, that’s the term used by Wikipedia cognoscenti to describe actions that aren’t approved by the general Wikipedia community) the article, I am relatively certain that the world will not collapse into barbarism and a new Dark Age.

If it looks like a duck...then it must be Quack medicine
Mar/03/09 22:29
One of the largest wastelands of medical science is something that has evolved into being called Complementary and Alternative Medicine (CAM). What is CAM? There’s no clear definition, but the epicenter for this pseudo-medicine is the National Center for Complementary and Alternative Medicine (NCCAM) which was funded by the US Congress to be a part of the National Institutes of Health. They define CAM as CAM is a group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine. The most common CAM therapies are homeopathy, chiropractic, acupuncture, naturopathy and herbalism. Typical of most pseudosciences, it does not rely upon the scientific method to generate results, it usually appeals to emotion, such as the great Big Pharma conspiracy against these potentially life-saving therapies.
I think that individuals should choose the therapy that they want, especially if it does no harm. If I had a chronic and terminal disease, I might choose an alternative therapy. If someone chooses to consume vast amounts of vitamin C to prevent cancer, despite little or no evidence that it works, that is their choice. What is troubling is when CAM is offered as an appropriate replacement to evidence based medicine, that is, “the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.” Best evidence relies upon scientific and clinical research, publication in peer-reviewed (and respected) journals, and sometimes, the opinions of respected authorities in the field.
The National Institutes of Health is a US government agency responsible for biomedical and health related research. One of the “centers” of NIH is NCCAM, which was established in 1991 by order of Congress. In fact, Senator Tom Harkin (D, Iowa) pushed for the formation of the center because he had been cured of allergies by taking bee pollen supplements, despite the fact that there is no scientific evidence that bee pollen would do so. In fact, there’s more evidence that bee pollen will cause an adverse allergic reaction. Read More...

Vaccines...Part II
Feb/25/09 09:37
If you read what I have written so far, I am firmly against pseudoscience influencing healthcare policy. Anti-vaccinationists, who have harmed human beings with their pseudoscientific assertion that MMR vaccines cause autism, are now on the run as I’ve stated earlier. Read More...
Vaccines...who are you going to believe?
Feb/19/09 15:51
In one corner, we have Jenny McCarthy, former Playboy Playmate of the Year, Dr. Andrew Wakefield, and pseudoscience with an extra dose of quackery. In the other corner, we have the Centers for Disease Control, the Institute of Medicine for the National Academy of Sciences, UK’s National Health Service, and the National Vaccine Injury Compensation Program (what is commonly called the Vaccine Court). The battle is over MMR vaccine, a mixture of three live attenuated viruses administered by injection for immunization against measles, mumps and rubella (formerly known as German measles).
Let’s take a close look at the participants. First, Jenny McCarthy, whose extensive medical and science education includes....not much. In 2005, she announced that her child was diagnosed with autism, a diagnosis about which there is some doubt. McCarthy believes that vaccines caused her son’s autism, although that view is unsupported by any scientific or medical evidence. Her public appearances and statements have increased the public perception of this link, and may have led to decreased immunization rates and increased incidence of measles. McCarthy has stated that chelation therapy helped her son recover from autism. Essentially, McCarthy claims that mercury in vaccines causes autism, which has been rejected by scientific and clinical studies. In fact, the National Institute of Mental Health has concluded that autistic children will not receive any benefit to balance the risks of cognitive and emotional problems induced by the chelating agents used in this treatment. Really, she should stick to modeling and bad movies.
Dr. Andrew Wakefield is a whole different story. He, and 12 other researchers, published a paper in the British medical journal in 1998, The Lancet, which reported on 12 (yes 12) children with developmental disorders. They linked eight of these children to MMR vaccinations. The paper described several bowel symptoms and the possible link to the vaccine. He even gave a name to the syndrome, autistic enterocolitis. After publication of the paper, confidence in the MMR vaccine fell; pediatricians in the United Kingdom thought the British government was either hiding evidence of the link, or was failing to prove it.

Linking to Wikipedia
Nov/06/08 12:16
Just a brief housekeeping note. Many of the links in this blog will point to an associated Wikipedia article. I, in fact, read and edit those articles, so I won’t make a link to an article that doesn’t make my point. It is supposed to be the epitome of a democratic encyclopedia, one that anyone can edit. It is free to read, and it has become the number one hit for almost any key subject, whether popular or obscure. Other than Obama’s own websites, the Wikipedia article about him is the first google hit. Read More...
