How long will it be?

19 Apr

The demonisation of the disabled has always been with us. The purposeful assigning of negative characteristics in order to worsen a case or point of view. Sometimes the people doing this are the very parents of the disabled people in question. Autistic kids have been called ‘toxic train wrecks’, ‘walking nightmares’, ‘unreachable’, ‘soulless’, ’empty shells, ‘dead inside’.

So, I have a nasty fear, shared by Asperger Square 8 and MOM-NOS that at some point, the murderer of several teachers and young people in a gun rampage in Virginia will be diagnosed by the media as autistic.

Here’s one media description of the murderer:

He was always really, really quiet and kind of weird, keeping to himself all the time,” he said. “Just of anti-social, didn’t talk to anybody. I tried to make conversation with him in August or so and he would just give one word answers and not try and carry on the conversation.”

Sound familiar? Yeah.

Or maybe he was just rude and didn’t like people. he did, after all, kill several of them.

On the EoH yahoo group one poster says:

Wonder if they can run that urine test polyprophilin???? on him for mercury poisoning. I bet that kid is toxic as all get out.

John Best chips in with:

The article says he didn’t make eye contact with his room mates and didn’t acknowledge people greeting him. That sounds familiar.

And when otehrs expressed skepticism that the murderer was on the spectrum, John explained why he wanted him to be:

If he was on the spectrum, then the shooting becomes the fault of Neurodiversity for encouraging him to celebrate the difference instead of getting cured.

Nice. Forget that people have been killed here, lets twist this to get at a group of people we don’t like. How respectful.

Thankfully, Erik put John right:

John, I hate the neurodiverse philosophy of no treatment/no cure, you know that. But what you’re saying is way off base.

But isn’t it amazing how even the parents of autistic kids are so very willing to see their own kids as similar to this murderer? Amazing and scary.

Also on EoH yesterday, a poster posted this link (warning – not nice) which is a petition to ‘kick out autistic retards from America’. The poster described how horrified she was by this petition. Me too. Its appalling.

But look at the wording of the petition:

In the past 15 years autism and mental retardation rates amongst children has skyrocketted. One out of every 100 children born in America is either retarded or autistic. Soon autistics and retards will make up 30% of the American population (and that’s a lot.) They do not deserve to live in America, not to mention that they take our tax dollars and our welfare money because they require special education and can’t work beacause they can’t communicate. Taxes will go up drastically in the next 20 years because of them.

Epidemic rhetoric, financial cost epidemic and demonisation. In a slightly differing context, I could easily have been reading a press release from the National Autism Association or the mainstream media.

If you have popularised the epidemic rhetoric, if you have popularised the financial cost rhetoric against autistic people then please know that you are not too dissimilar from this odious individual.

Autism should not, ever, be demonised in order to score political points. There is _no evidence_ to support the idea of an epidemic. There is _no evidence_ that autistic people are crazed killers. How is this advocacy? How does it help?

Lisa Sykes and Paul King: CoMed with a silent ‘y’

17 Apr

One of the more extreme quackery groups formed post-EoH is CoMed (the ‘y’ is silent) which is run by the Rev Lisa Sykes and Dr Paul King recently emailed a large group of people with a PDF Press Release that tried to make the case that autistic children were proven to be clinically mercury poisoned.

How did they reach this earth shattering conclusion? By stating that two papers and one methodology backed them up. Have a read of the document – its a fascinating example of how the militia attempt to ‘spin’ the reality of the situation and try to make things sounds like a given. Note the silent switch about halfway through from talking about ‘mercury’ in general to talking about ‘vaccines’ in particular.

Anyway, Sykes and King were good enough to note only post this press release on EoH but also to tell the group exactly who they had emailed – a motely crew, ranging from fellow whacko’s like David Ayoub to Governer Arnie “I’ll be back” Schwarzenegger, plus a host of journalists, lawyers etc.

So, I thought I’d better put these poor people straight and consequently sent them a letter. This is what I sent them:

Dear Madams and Sirs,

Firstly, please accept my apologies for the unsolicited email. I hope it is not intrusive.

I wanted to write to you as you were the recipients of a recent email/PDF press release from the group ComEd regarding their belief that ‘Autistic Children Clinically Proven Mercury Poisoning’. I wanted to offer an alternative to this erroneous belief. I will cite any references I make and I promise to keep this brief.

The ComEd press release uses two studies[1,2] and a technique as the ‘mainstay’ of its certainty that autistic children are clinically proven to be mercury poisoned.

The Geier paper [1] is an attempted replication of the Nataf paper [2] and suffers from its same substantial drawbacks.

Issue one: The role of precoproporphyrin.

Nataf et al claim that the presence of elevated precoproporphyrin is a specific indicator of mercury toxicity. They do this on the basis of three studies produced by one author[3,4,5]. When these studies are read properly, if we ask the question “Does exposure to heavy metals cause a relative elevation for certain porphyrin compounds in urine?” the answer would appear to be “Yes.” However, If we ask the question “Is the presence of certain urinary porphyrin compounds a specific indicator of heavy metal toxicity?” the answer would have to be “No”[6]

The Woods papers are interesting but far from conclusive enough for the Nataf and consequently Geier papers to reply on.

Issue two: Creatinine and the subsequent UPPA technique

In their press release ComEd claim that the UPPA (urinary porphyrin profile analysis) technique is a ‘highly accurate’ method of determining toxicity. Indeed, it is the method used by the Nataf and Geier papers. In this method, the urine of children is collected and analysed for the presence of porphyrin’s. If they are elevated then QED: the children must be metal poisoned.

Except its not as simple as that. The content, volume and dilution of urine varies considerably from patient to patient. The way around this issue is to measure a secondary constant element from the urine and compare the amount of porphyrins found against the amount of this compound and express the result as a ratio. This is what Nataf, Geier and the UPPA technique does. It utilises creatinine – a constant in urine – to provide a baseline figure and thus get an accurate percentage of porphyrins.

This is a standard way of measuring compounds in urine. The only issue is found when the population in question (autistic children in this case) are known to have significantly low levels of creatinine. Obviously, this would skew the results considerably and present a false reading of elevated porphyrins.

Is there recorded instances of low creatinine in autistic kids? It seems that there might be.

“Spot urinary creatinine excretion in pervasive developmental disorders” published in Pediatrics International[7], reports low creatinine levels in PDD:

a significant decrease in urinary creatinine concentration was found in the PDD group compared to controls using a Mann–Whitney two-tailed ranks test.

Of course, this just one study. Its a good start but thats it. But maybe its interesting that the group of maverick DAN! doctors (of whom one is treating Rev Sykes of ComEd’s autistic son I believe) also find low creatinine in autistic kids[8]:

“”Creatinine is often found to be marginal in the urine of autistics, and low creatinine can skew urine analyte results to high levels. So, also take note of creatinine levels if the laboratory results include ratioing to creatinine.””

I engaged in an email exchange with Professor Richard Lathe, secondary author of the Nataf paper[2] regarding the study his group had published and I questioned him at length regarding this creatinine issue. He said:

1.There was no significant decline in urinary CRT levels in any of the autism groups, though there was a non-significant trend to a reduced level. 2. Reduced CRT, and increased porphyrin, both appear to be markers of environmental toxicity.

However, neither of these observations were reported in the published paper. Lathe described it as ‘pointless’ to publish all data. I disagreed with him citing the uncertainty over creatinine levels and he conceded:

The long and short of it is that the response of CRT to different levels of heavy metal toxicity has not been studied adequately.

Which is a troubling statement considering that his paper required CRT to be well understood and to be functioning as described in order for the science in the paper to be accurate.

Lathe also conceded that other key parts of his paper (and consequently the UPPA method) were in doubt and relied on science that had been refuted and thrown out of court when attempted to be used in private prosecution[9]

The UPPA method has been in use for some time amongst adherents to the theory that mercury poisoning (notably from vaccines) causes autism. I have found numerous emails to a private access Yahoo Group called ‘chelating2kids’ which details peoples experiences with this method. Here are just three.:

1: “A fellow listmate had her son tested twice– once over the summer which showed he had no elevated metals, and one this fall that showed he did indeed have elevated metal levels. She has sent an email to the lab asking about the differing results and has not received a response. I believe she is still trying to contact them”

2: “FWIW, my neighbor’s dad happens to be a porphyrin specialist here in Boston (believe it or not– how many of those are there??). He reviewed lots of info for me– Nataf’s paper, my son’s results that showed very elevated metals across the board– and said he would have rejected the paper for publication had he been asked to review it. He said that fecal, not urine, should be used to measure the porphyrin levels. I sent an email to the lab inquiring about this and also received no response”

3: “I just received the results of the French porphyrin test for myself and my 7 year old NT [NeuroTypical – i.e. non autistic] daughter, and the results also show severe lead and mercury toxicity. My daughters numbers are worse than my ASD son!”

In closing, I would suggest that any assurances that mercury poisoning as a causative agent of autism are even likely, let alone ‘clinically proven’ should be taken with a very large grain of salt. I would also suggest that Rev Sykes role as an anti-vaccine activist and vaccine/autism litigant[10] are taken into account when considering the validity and motives of this press release.

Thanks for listening. My motive for writing this email is that, as parent to a severely autistic seven year old girl, I am sick to death of hearing bad science and media-driven misrepresentations attempt to coerce from autistic people what they truly need – decent, peer reviewed science which lead to good educational interventions for all autistic people. Thanks again.

I’ve had a number of fascinating responses, but my far and away favourite response was:

thank you for your email it has made it easier to apply you to my junk filter even though the junk file is far to good for the likes of you sir.

Which I received from one David Ayoub MD. The same man I publicly challenged to a web based debate less than two weeks ago on a third party letters page and who backed down.

Update: 18th April 2007

Dr King of CoMed produced a response to my rebuttal. You can read that here. and I couldn’t resist one more frolic through the CoMedy logic,as you can read here.

Autism, Chelation and Quackery

15 Apr

Mercury Mum, Christine Heeren recently posted a video of her son receiving IV chelation on YouTube.

UPDATE: Shortly after this blog post went live, the YouTube video disappeared. Luckily I had already grabbed a copy which you can view here:

http://video.google.com/googleplayer.swf?docId=-5984127405622843714&hl=en-GB

Its a disturbing video on many levels. Heeren’s son has been undergoing chelation for seven months now and is still clearly totally autistic. During this video he is apparently writing ‘bus numbers’ down. The blog that Ms Heeren keeps (link on YouTube page) also makes it clear that her son still stims and he displays many common outward signs of autism (the scrunching up of the eyes at the start of the video reminds me of something my daughter does very much).

Heeren is subjecting her son to the Buttar protocol which should give anyone the stone cold heebie jeebies in and of itself. One patient of Buttar’s said that:

I find that Dr. Buttar talks a lot but produces little evidence.

And another said:

All the information about Dr. Buttar is still on this site but I no longer am one of his patients and I do not recommend him to any one for any reason. If you go to him for treatment BEWARE, BEWARE and read Roger Mason’s books first and go to QuackWatch.org first!

However, maybe we should take some kind of solace from the fact that Heeren’s doctor is not actually Buttar himself, only trained by Buttar. Maybe he’s a good doctor.

Heeren’s doctor is Muneer ImamMuneer Imam a shy, kind looking man wouldn’t you agree?

Well, he may well be.

In Jan 1993, the New York Office of Professional Conduct charged Muneer Imam:

…with gross negligence, gross incompetence, negligence on more than one occasion and failure to maintain adequate records.

The Hearing Committee sustained the charges of negligence on more than one occasion, incompetence on more than one occasion and failure to maintain adequate records. The Hearing Committee found Imam guilty of careless practice, lack of attention to detail and failure to appreciate the severity of patient illness

The incidents have included at least one death of a patient under the care of Imam.

The Hearing Committee (incredibly in my view) said he could probably be rehabilitated and laid out a plan of rehabilitation.

This all took place under Imam’s work at an ER. Imam no longer does ER work. I asked a medical friend about why that might be and xyr response was:

Since he no longer seems to do ER work, I imagine he settled a med mal claim for deceased patient A, and his insurer refused to write coverage for ER work and no hospital would cover him

Is this really someone any parent would want to trust with the kids life? A doctor found to be incompetent, negligent and who doesn’t pay attention to detail?

This inability to pay attention to details certainly seems to be playing out on Heeren’s video. Here is Imam’s nurse (a Vietnam vet called Nick) fitting the IV for a course of chelation.

No sterile

When I showed this to my medical friend xyr response was horrified:

WTF is this alleged nurse doing starting an IV without gloves??? What happened to sterile technique? Have they lost their minds?

and

What is this alleged nurse doing using that frigging tiny gauge needle???

It seems that the chelation protocol Buttar uses specifies a 22 gauge butterfly needle, not the tiny one seen in the video. There are good reasons why:

…..because this is the easiest to use for employees with no medical training who call themselves “chelation technicians.” The tiny needle also serves to prevent patients from killing themselves by increasing the drip rate when they’re sick of sitting around for hours. Increasing the drip through a 22 gauge butterfly needle should (in theory) burst the vein before delivering Endrate at a lethal rate. Clever stuff.

While almost everyone can start an IV with this tiny needle, it’s dangerous to use for chelation because if patients get into trouble you want a large bore needle inserted in case you need to administer drugs and fluids for treatment or god forbid, resuscitation. Starting a second IV with an appropriate size needle in a patient in circulatory collapse from shock is difficult and sometimes impossible. The daunting prospect of starting an IV in the jugular makes sane physicians do everything to avoid being in this position.

Administering a bolus of calcium gluconate to counteract hypocalcemia through this tiny needle can result in a swollen hand (when the IV infiltrates) attached to a dead patient.

So – Nick the Nurse also has incompetence issues.

At one point in this video I thought I had gone mad. Did my ears deceive me or did I really hear Nick the Nurse describe how they also chelated with vinegar and garlic? I rewound the video. Yep, he said it alright. Vinegar and Garlic. I could say ‘wow’ or ‘holy crap’ to express my incredulity after hearing that but really, no words do it justice. They are chelating this poor lad with Garlic and vinegar.

And why? What for? First test

Here is Heeren’s son’s first ever lab report (click the image to get a bigger one).

Let’s remember that these lab reports are all part of the quack culture and I suspect are frequently exaggerated to get the parent to use more of their treatments. If even these results are exaggerated then I’m dumbfounded. Everything except Aluminium and Lead are within normal ranges. And even those two are just barely in the elevated range.

It is on this basis that Heeren decided to start chelating her son using a doctor described as medically negligent and incompetent under the tender care of a ‘nurse’ who doesn’t know the protocol he is supposed to be using and who is actively putting this boy (and presumably others) in potential danger.

Oh and don’t forget the garlic and vinegar. Thanks Rashid, thanks Muneer, thanks Nick.

Katie Wright’s big day

6 Apr

Yesterday three big things happened to Katie Wright. Firstly, she joined the board of Directors of SafeMinds. Secondly she joined the board of directors of the National Autism Association. Thirdly, she appeared on the US Oprah Winfrey show.

The elusive Ginger blogged the NAA and SafeMinds news which was announced just before/during/after (depending on your timezone) the Oprah show.

The Opera show itself was a mixed bag apparently. There was a lot of self pity at the start:

“he’s not there, I don’t know where he is but he’s not there”

Oprah: A mystery affecting millions of families

“A bad day is a bad day and a good day is a bad day waiting to happen”

Please. Spare me. Not there?

However, a lot of people have also said there were some great moments:

I like the way the show ended with every single parent talking about the gifts their autistic children have given them! “He has made me more spiritual,” “He has made me look outside of myself,” “He takes people just as they are.” “He has given me someone to love way beyond what I ever thought possible.” Amen.

Sue also noted that no autistic adults were on the show and none were interviewed. That’s ridiculous.

However, part way through the show was the Katie Wright Experience. Apparently what happened was that Oprah asked a Doc on the show about vaccines and he repeated the scientific consensus – which is that vaccines have been refuted as a cause. Which is true. The show cut to a break. When it came back on, viewers were greeted by a visibly pink and flustered Katie Wright and then the host of the show told the audience that …..in fact I’ll quote from someone (who I won’t name so don’t ask) who was watching the show carefully:

To me it all seemed quite sane, except for Katie’s little blurt. A pediatrician of south Asian descent whose name I didn’t catch was periodically consulted from the dais by la Oprah, and gave what sounded like reasonable advice. At one point Oprah asked about causes–she didn’t use the word epidemic but said ‘what the cdc calls a health threat–and the pede gave a general response, genetics, possibly some environmental thing, and then Oprah said, “what about vaccines?” the pediatrician responded, “that’s controversial.” and oprah said, ‘well yeah, and?” or words to that effect. The pediatrician said the vaccine theory had been pretty well refuted. That was that, but after the next break, Katie Hildebrand, who was sitting next to Oprah, must have been chewing her ear off because la O told her to say her piece which she did in the usual incoherent shrieking way, “vaccines are not cleared of being responsible, children are given 37 different vaccines, my child has all kinds of immune problems, there’s an epidemic that keeps growing” etc. Oprah said, “there i can see you needed to get that off your chest, you don’t want to go home with that all bottled up. After all, you’re a mom.” the studio crowd applauded though they did not hoot or yell anything specific that i could detect on my tv screen.

Following that, Oprah apparently told the audience that this is what _Katie_ personally believed and it wasn’t supported by any CDC evidence.

Here’s _my_ summation of Katie Wright’s life at the moment.

Katie campaigned to get a Generation Rescue member on the board of Autism Speaks. Here’s how Brad Handley reported that event in a rant:

Kevin Barry, our former President, was hired by Autism Speaks. On his first day of employment, Mark Roithmayr informed Kevin that he was only there “as a favor to Katie” [ the mother of Bob and Suzanne Wright’s autistic grandson]

Katie has spoken of Brad and Kevin Barry as her mentors. Here’s Brad’s mention of Katie Wright:

I just want to share how damn proud I am of this family. Remember, there is no Christian Wright, his name is Christian Hildebrand.

Katie’s decision to be more public about her point of view is not some impulsive move. For almost two years now, quietly but firmly, she has lobbied her parents on the growing morass that Autism Speaks was becoming. By choosing to listen more to the “experts” than their own daughter, Katie’s parents selaed their own fate.

Two years. After which the Wright’s continue to listen to science, not Brad’s people.

Katie Wright has come to believe, after a long association with Brad Handley, that vaccines caused her sons autism. Katie had the king Rescue Angel himself hovering over her for the last two years. Has anyone ever told Katie that Brad is often wrong and never admits it even when its clearly demonstrated? I guess not.

Kim Stagliano (autism blogger – big on pooh) said:

This is a very big day when the SS Minnow overtakes the Titanic.

Really? _Really_ ?

From all I’ve read and seen, all that’s apparent is that the newest mercury mum on the block got appointed to two antivaccine groups and that made a bit of a fool of herself on television. The only difference is that this mercury mum happens to have parents who own and run an autism organisation that she’s just cut her ties from.

What I actually feel the Wrights are guilty of is: Listening to dinosaurs with degrees instead of their daughter, Deirdre Imus, and others speaking the truth, myself included.

In Brad’s world there is no greater sin than not listening to him. Maybe they did listen to you Brad and thought you were wrong.

So, after Katie Wright’s big day – the day the SS Minnow overtook the Titanic – what’s changed?

The world saw a visibly unstable mercury mum on TV being thrown a bone to rant about her pet theory for a few minutes and then the show carried on.

…and thats that. No scientific facts changed yesterday. Katie Wright confirmed herself as a woo-meister. All that means is people will be even less likely to listen to her than they were before. Autism Speaks must be breathing a sigh of relief she’s jumped ship.

MMR and Autism – 2007 is the year

1 Apr

This year, the Autism Omnibus hearing in the USA will examine the idea that MMR causes autism. They will do this by taking one of the plus 4,500 cases and looking at it as a ‘test case’. The case in question is the Cedillo family, mother Theresa (just a coincidence), father Michael and daughter Michelle.

The document above by the way establishes that they want the evidence they accumulate to be open to the other families but that they do not want the identities or the evidence of their expert witnesses to be made available online. I wonder why. If I may be so egotistical, it could have something to do with the fact that several bloggers have trounced both the data and the experts and they don’t want this happening any more.

Anyway. What do we know about the Cedillo’s?

We know that Michelle’s bioposies were examined by Professor O’Leary, one time colleague of Andrew Wakefield who went on to have his own results seriously questioned and who went to say:

Professor John O’Leary, who did the tests for solicitors representing the families of autistic children, said his scientific findings “did not support the MMR/autism hypothesis”.

We also know that Michelle was seen by Arthur Krigsman, who, despite claiming to replicate Wakefield’s discredited Lancet paper has had no papers on autism, or vaccines published at all. What he has had however, are numerous close calls with licensing bodies – in one instance he had to resign in order to escape official investigations into his conduct.

And what do the Cedillo’s believe has happened to Michelle?

We just found out the left hind foot bones in Michelle’s foot are deformed. Instead of being one on top of the other, they are growing side by side. Michelle is on pain meds nearly around the clock. She limps and walks with a side to side gait instead of forward like normal. This was caused by the Crohn’s associated arthritis (confirmed independely by 2 orthopedic spec and a ped rheumatologist AND Dr. Krigsman and Dr. Wakefield), which was caused by the Crohn’s disease caused by the vaccine strain measles RNA found in her bowel tissue from the MMR. Michelle gets periodic ocular inflammation – also from the Crohn’s disease. This gives her headaches.

Its terrible that such a young girl is in so much discomfort. But looking past that and concentrating solely on the science, we see that the Cedillo’s believe that Michelle contracted Crohn’s disease brought on by the measles element of the MMR.

So – Crohn’s _and_ autism? Searching VAERS, I find only seven cases that refer to ‘crohn’ and had the MMR vaccine. That’s pretty rare.

Even those who might be expected to support the MMR/autism hypothesis don’t. In an email to the Autism Biomedical Group on March 08, 2004, Vice President of SafeMinds Mark Blaxill stated:

epidemiological evidence (albeit from studies that have not carefully considered interaction issues), have not supported the broader proposition that “MMR causes autism.”

I will be very curious to see exactly who their experts are and what their evidence will be. If it really is, as I suspect, Andrew Wakefield, then they won’t be able to choose a worse time to invoke his ‘expertise’. Wakefield’s hearing at the GMC starts at about the same time.

Here’s a beginners guide to the MMR/autism hypothesis and what Wakefield claims to have found. The hypothesis states that the MMR vaccine, being a live vaccine, leaves bits of live Measles virus in the gut. Wakefield claimed to have found it there. This goes on to trigger autism.

No part of this hypothesis has ever been replicated and published in a decent journal. Wakefields closest colleague – Krigsman – has been unable to find a publisher for his ‘replication’ which indicates the quality of _his_ science. As reported above John O’Leary claimed to have replicated Wakefield’s work but it turned out there was a good chance his data was contaminated and he later stated none of his work showed a connection. Various epidemiological studies have also failed to find any link (as Mark Blaxill admits).

We also have two clinical science papers that demonstrate convincingly that Wakefield did indeed make a substantial error. One Paediatricsin Pediatrics was very damning:

The real-time assays based on previously published primers gave rise to a large number of positive reactions in both autism spectrum disorder and control samples.

Translation: We replicated Krigsman/Wakefield etc to their end point and there were lots of measles virus just like they said.

Almost all of the positive reactions in these assays were eliminated by evaluation of melting curves and amplicon band size.

Translation: We did the science properly just like they didn’t. When we did most, but not all of the positive reactions disappeared.

The amplicons for the remaining positive reactions were cloned and sequenced. No sample from either autism spectrum disorder or control groups was found to contain nucleic acids from any measles virus gene.

Translation: When we looked at the rest of the very small number of positives we had left we found no measles virus in any of them.

In the nested polymerase chain reaction and inhouse assays, none of the samples yielded positive results. Furthermore, there was no difference in anti-measles antibody titers between the autism and control groups

Translation: We double checked our methods and tools and there were now _no_ positive reactions at all. Further more, just for clarity – there were none in our non autistic people _or our autistic people_.

It’s going to be very, very difficult for the Cedillo’s to overcome this.

Now, closer to home (for me anyway), there are a couple of new papers that discuss what impact the MMR really _did_ have on people. Here’s some real evidence of harm.

In “Tracking mothers’ attitudes to MMR immunisation 1996–2006“, we hear the alarming statistic of how much damage Wakefield et al did to the UK MMR program:

The proportion of parents believing MMRto be a greater risk than the diseases it protects against has fallen from 24% in 2002 to 14% in 2006. The proportion of ‘hard-core rejectors’ of MMR vaccine remains stable at 6%. There has been a gradual and sustained increase in the proportion of parents across all social groups saying MMR was completely safe/slight risk rising from 60% in 2002 to a current level of 74%. There now appears to be a sustained move away from fears over MMR safety and belief in the unfounded link to autism towards a more positive perception of the vaccine.

It a relief that the authors believe there is a sustained move back towards a more rational state of mind regarding MMR but its incredible that 24% of people ever believed that MMR was more risky than the diseases it protected against.

Its no surprise then, that in the years 1997/98 – 2004/05, MMR uptake dropped by a massive 10%. Of interest, when comparing that _fall_ in MMR uptake is the epidemic rhetoric that claims autism is sweeping the UK too. Both things can’t be true. If MMR causes autism then however one paints the stats, there should’ve been a 10% fall in autism.

One group of people truly have suffered through this period. They have been the front line recipients of the bad science of Wakefield et al: parents of autistic kids.

In the new paper, “MMR: marginalised, misrepresented and rejected? Autism: a focus group study“, investigators interviewed parents of autistic kids:

Of the parents whose children received the MMR vaccine, many felt guilty that they may have caused or contributed to their child’s autism. Some parents felt frustrated by health professionals’ lack of understanding of the negative impact the MMR controversy has had on them. Some parents were anxious about subsequent MMR decision-making for their children.

This is the legacy of Andrew Wakefield. Parents who are guilt ridden and unsure who to turn to. The study conclusions state:

The controversy has had a negative impact on some parents of children with autism. This has implications for health professionals, who need to be particularly aware of the issues these parents face in future MMR decision-making for their affected child and younger siblings.

These focus group discussions produced moving and often emotional accounts of parents trying to come to terms with their child’s diagnosis of autism against a backdrop of widespread public speculation about the role of the MMR vaccine in the aetiology of autism.

As Jim Sinclair states in his essay ‘Don’t Mourn For Us’:

Some amount of grief is natural as parents adjust to the fact that an event and a relationship they’ve been looking forward to isn’t going to materialize. But this grief over a fantasized normal child needs to be separated from the parents’ perceptions of the child they do have: the autistic child who needs the support of adult caretakers and who can form very meaningful relationships with those caretakers if given the opportunity.

The parents in these focus groups (and remember these people were interviewed when the MMR conspiracy theory was still well underway) never had a chance to move past the natural adjustment period and on to acceptance. When the media and ‘scientists’ continue to express certainty despite having absolutely no evidence that MMR causes autism its hard to get past the guilt. I know. That’s how I felt as well.

Parents often spoke angrily about how the MMR controversy had impacted on their lives. Even parents who stated that their
child’s autism was entirely genetic in origin felt affected by the uncertainty about the causes of autism which were heightened
by the controversy. For example, one mother who thought her son had been born with autism nonetheless found the speculation surrounding MMR upsetting, and stated that: … it makes you feel pretty damn rotten. I feel as if at the time I did the best for my boy… I wouldn’t have put my child through anything that I think would harm him. (G1: P3)

Thanks again Andy.

Katie Wright and Autism Speaks – woo confirmed

29 Mar

For the last few weeks the subject of ire on the EoH maillist has been Autism Speaks, they’ve been the subject of some very nasty descriptions indeed. The reason is that the EoHers knew that Katie Wright, daughter of the owners of Autism Speaks, was taking her son Christian to a DAN! doctor and yet Autism Speaks were keeping this quiet.

Well, as blogged by David Kirby, Katie Wright has now confirmed that Christian is seeing a DAN! doctor (lets hope its not one of the paedophiles or Scientologists) and has gone ‘on the record’ as stating she believes vaccines caused Christians autism.

The mercury militia and David Kirby report this:

Many in the upper echelons of Autism Speaks have rejected any environmental hypothesis and insisted that autism is purely a genetic disorder — though Bob and Suzanne Wright (and the organization itself) remain officially neutral on this crucial question.

But now, Christian is getting better, and that wonderful news could change everything.

Well, firstly, I can’t recall anyone from Autism Speaks insisting that autism is purely a genetic disorder. If they did I think they’d be just about alone. Secondly, ‘Chrisitan is getting better’. Really? How is that described exactly?

“He’s definitely getting better,” Katie told me by phone. “He was a very sick kid, with an extended gut and inflamed intestines. We couldn’t do anything until we got that under control.” But once Christian started to improve physically, she said, he also began to get better emotionally, mentally and cognitively.

When Christian’s gut improved, his parents began trying other, still-unproven treatments like dietary changes (no wheat or dairy) chelation therapy (removal of heavy metals from the body) and methyl B-12, which could help restore a critical process called methylation – a needed tool for detoxification and proper nerve function that is apparently deficient in some autistic children.

“Christian is speaking now, though only when prompted,” Katie told me. “His eye contact is returning, and his crying and tantrums have subsided.” And she said, “His ability to attend has returned. Now he can sit and do his lessons and learn, whereas before he would just lie down and scream in pain, because his abdomen hurt so much. But he still has a long way to go.”

Perhaps most heartening to Katie is that Christian can now tolerate being in close contact with his brother, something that used to send the boy into screaming fits of anxiety.

Well I too am glad that Christian doesn’t have these gut problems anymore. But these aren’t autism and have nothing to do with autism. My daughter, who is also autistic, has never had an ‘extended gut and inflamed inststines’. Thats not to downplay Christian’s problems but its simply not realistic to equate these things with autism.

Christian (who is 5 and yet described by Kirby as a ‘toddler’) displays very similar behaviours to Meg at five (and at three) – she didn’t speak at all, she struggled with eye contact and she had big meltdowns. The thing she has in common with Christian is that their changes have occurred as they have grown older.

Kirby goes on to say:

So how will some Autism Speaks officials react to Katie’s statements? They could fall back on two recent, but highly inconclusive studies that support the autism-is-genetic paradigm, and continue to reject the environmental hypothesis. But I wouldn’t bet on it.

I’m unsure exactly what two recent genetic studies Kirby is talking about as he doesn’t name them but if they are written by decent scientists then I highly doubt they have written an off-the-cuff rejection of an environmental aspect to autism. If anyone does know what studies Kirby is referring to please say so I can check for myself. I find double checking Kirby’s words often reveals interesting things!

But hsi question is a good one. How _will_ Autism Speaks react? They are a ‘house divided’. They have the scientific teams that they inherited from NAAR and they have their ‘in house’ members that are media people. Will they go for the media or for the science? It seems that Kirby and the mercury militia are in no doubt about which way they _should_ go – they want a media driven Autism Speaks. An organisation that abandons science for woo.

It should be noted that the mercury militia are very, very good at media manipulation. From Brad Handley’s full page ads to Katie Wrights levering of Kevin Barry to get onboard Autism Speaks and of course, David Kirby’s fact free and often hilarious debating points. These are not people who let a media chance go unexplored. However, they cannot force science to show something that it does not.

Education data is the new black

26 Mar

Or, more accurately, Education data is the new CDDS.

Up until this year, David Kirby, Lenny Schafer, Rick Rollens et al said that CDDS data was the gold standard of autism data and because rates were rising during the 90’s according to CDDS data this proved that vaccines caused autism. Then they said this would be proved in 2005 – sorry, 2007 – when it was firmly established thiomersal was pretty much out of all vaccines in the US schedule excepting the voluntary flu jab. Kirby went so far as to say that if the CDDS rates didn’t fall by 2007 then this would be a significant blow to the thiomersal theory.

Guess what? No fall. In fact, there was a continued climb.

Next they all said – CDDS? That stuff is rubbish – California is ‘special’. No, no, no, what _really_ counts is educational data. In fact, just this morning, the latest Schafer Autism Report carried new data that showed how autism rates were still climbing.

But hang on….seeing as we _know_ that the amount of thiomersal in vaccines is essentially nil, and tests show that as early as 2002, over 80% of doctors surgeries reported they carried no thiomersal containing vaccines, how can we possibly carry on with the stupendously idiotic hypothesis that thiomersal in vaccines causes autism?

Feh. Never mind. Thiomersal is out of favour these days. These days its all about Aluminium or whatever other vaccine ingredient people want to wring their hands about.

Anyway, here’s a post I came across on EoH today:

I just found this newsletter from last fall- vaccine rates dropping funding short- sounds good to me. Too bad we are not counting AUtism rates like CA.

and it linked to this PDF which says:.

Alarmingly, our childhood vaccine rates have dropped from the highest in the nation to just below the national average. From 90% of two year olds fully immunized to less than 80%.

The inference is clear, right? If only we could count the number of autistic people in Maine up to and including 2006 I bet we’d see them dropping as the vaccine uptake in Maine dwindled. And hey – this should be an easy drop to find in the state that had the highest vaccine uptake in the nation, right? Oh, if _only_ someone had tracked the autism numbers in Maine!!!

Well, worry no more – the great guys at the Vaccine Autoimmune project have. (IE link only, poor web development ahoy!). Lets take a look shall we?

State 2000-2001 2005-2006 Percentage Increase
Maine 150 311 107

Huh??

Wait now…you mean to tell me that vaccine uptake _fell_ over 10% and yet autism _increased_????

Miraculous – whatever can it mean???

Ayoub/Yazbak/Fombonne

8 Mar

_Jonathon has posted an excellent summation which I entirely agree with on the Ayoub/Yazbak/Fombonne ‘affair’. I’ll include it here and shut off comments, including a link to Jonathon’s post for you to see references and leave comments._

_My one comment is to say that I think that Fombonne has a case to answer. I also hope that he will. I further think that the critical errors Jonathon highlights show clearly that the more outlandish claims that Ayoub and Yazbak have demonstrated correlation between MMR and autism are unfounded. They should’ve just stuck to the genuine and good quality criticism of Fombonne._

_The floor is now Jonathon’s: _

A Review of the Critiques of Fombonne et al. (2006)
Abstract

The critiques of Fombonne et al. (2006) do point some relevant problems with that study. However, they also use some considerably problematic arguments themselves.

Introduction

Fombonne et al (2006) attempts to correlate data between an increase in the number of cases of the Pervasive Developmental Disorders and vaccine use in school children residing in Montreal, Canada. That research failed to reveal any such correlation. In addition the researchers found a prevalence rate of the PDD’s which match what is seen in the US (Bertrand et al., 2001), the UK (Chakrabarti & Fombonne, 2001; and Chakrabarti & Fombonne, 2005), the Faroe Islands in Northern Europe (Ellefsen et al., 2006), and matches data on Autistic Disorder in Japan (Honda et al., 2005)

Recently, two web based articles have been released and promoted based out of the National Autistic Association website. These articles were written by Dr. David Ayoub & Monica Ruscitti for one letter and Dr. Edward Yazbak for the other. These authors raise important and damaging points which call into question the validity of Fombonne et al. (2006). I note however, that not all the points raised in these critiques have equal merit; in fact some of the points raised are most notable for their lack of merit. The points raised in the critiques are discussed below.

Review of Ayoub & Ruscitti

The authors point out that Fombonne et al. (2006) only uses data from only one of Montreal’s five school districts. This district is specifically an English speaking section. The authors accurately point out that a selection bias may have occurred here. In addition the authors note that Fombonne et al. (2006) claimed they could not gain access to the other school districts’ data. The authors then claimed they gained access to this data and make specific claims about a notably higher rate of autism in the school district Fombonne et al. used. I note that these data and analysis methods are absent.

The authors note that English is only the third most common language in Quebec, the largest group being French and the second largest being assorted foreign languages. The authors note that access is restricted to the English speaking school district by a law designed to help protect the French language. However, the authors simultaneously make the claim that this English speaking school is more inclusive than the others. This claim seems contradictory. It is possible that while the English speaking district is more exclusive in general it is in fact more inclusive towards students with disabilities. However this point is not explained.

The authors correctly criticize Fombone et al. (2006) for describing thimerosal laden shots as “nil”. The authors go on to describe vaccines in Canada that continue to use thimerosal. However, the authors fail to note that none of these vaccines are actually required any longer and for that reason exposure should not be comparable.

The authors mention that fourth graders largely participated in a voluntary vaccination program for Hepatitis B, which contains thimerosal. However, the DSM-IV mandates that Autistic Disorder first appear in a child by age 3, even if it is diagnosed later. Fourth graders do not develop autism. Also, and rather remarkably the authors cite Roy et al. (1999) which is concerned with the health and safety including vaccination based on high risk behaviors of street youth in Montreal. The median age of that study was 19.5.

The authors criticize Fombonne in the following terms:

“he ignored the fact that autism rates increased following a doubling of the MMR exposure after 1996 when a second MMR shot was added to the immunization schedule and chose to emphasize that a rise in PDD rates coincided with a decline in MMR coverage rates. Obviously the increased amount of administered viral load to the population was far greater influenced by a doubling of shots administered than by a marginal drop in immunization coverage rates. He likewise ignored the potential impact of mass measles immunization campaigns in Quebec that delivered a second dose of measles to a large number of infants and children throughout 1996. (11) The subsequent rise in PDD shortly after that campaign is clearly depicted in their figures and would lead us to believe this observation supports an association between PDD and MMR exposure.”

The above assumes that the drop in thimerosal was not only made up, but actually exceeded by the increase in MMR dosage. For this explanation to work, one must simultaneously assume that both thimerosal and the MMR can cause autism. A more parsimonious explanation would be that the rate of autism would have risen regardless, which is certainly what we see in other locations including the no longer mandatory thimerosal exposure in California.

The authors also state:

“Numerous reports of higher PDD rates among immigrants have been reported in Canada and other industrialized countries.”

This claim is demonstrated no where in any research. It even seems to contradict some actual research (Kamer et al., 2004).

The authors go on to assert:

“Finally the paper’s observation about rising PDD rates seems to contradict Dr. Fombonne’s well-known contention of the lack of evidence of an autism epidemic. In an Inserm interview, Dr. Fombonne said, “to declare an epidemic, or sensible increase of the prevalence, it would take incidence studies, always the same, year after year, but this data is not available in any country.” (12) The database we obtained from the MEQ represents the type of dataset Fombonne stated was required to detect true increases in PDD. According to one Montreal-based autism organization, data from the MEQ revealed an increase in annual PDD cases in Quebec from 410 (1990-1991) to 4,483 (2005-2006), a nearly 1,000% increase over 15 years. (13) This is staggering and is strong evidence of a real rise in neurodevelopmental illnesses that cannot possibly be solely genetic in nature but supports an environmental etiology.”

The above statement is presents a false problem. An increase in this data set may not be attributable to real change in the actual number of cases. The system could be open to a lack of control for the six threats to statistical validity. This is a well known problem in other administrative data sets in the world of autism.

Review of Yazbak

The author submitted an letter to the editor detailing concerns about uptake of the MMR rate in Montreal and the increase in the PDDs. The editor forwarded this comment from Dr. Fombonne:

“This person is known to pursue the MMR-autism agenda at all
costs in order to ‘demonstrate’ a link he strongly believes in. The only way ahead is to encourage him to do independent research. All controlled epidemiological research thus far has concluded to the absence of such a link.”

the editor of the journal had this to say:

“As a note, I believe the evidence of no link between MMR and Autism is sufficient. It’s not worth publishing more on this subject. We will not be publishing this exchange of correspondence.”

I disagree with Dr. Fombonne’s approach to this situation. It is not relevant that Dr. Yazbak believes in a vaccine etiology of autism. I also disagree with his failing to address Dr. Yazabak’s criticisms which are specific and serious.

I also heartily disagree with the editor’s refusal to publish Dr. Yazbak’ criticism. While it is certainly his job to ensure that all matters within the journal merit inclusion under a serious scientific aegis, Dr. Yazbak’s criticisms are specific and fall into known categories of scientific criticism. Whether or not he believes it has no beating on his responsibility to publish scientific criticism.

However, given the title Dr. Yazbak selected “Far-Fetched”, perhaps the editor had ground to refuse this letter or at least demand that it be re-titled. Pediatrics is a serious academic journal of high standard. In most such journals while a given level of sarcasm and dismissiveness is permitted, this seems to have crossed the line of acceptability.

Dr. Yazbak goes on to assert:

“When he was in France, Dr. Fombonne was a well known psychiatrist who published articles on psychiatric topics. He was still a psychiatrist when he moved to England …until Andrew Wakefield suggested that the link between MMR vaccination and autism should be further investigated and suddenly …Dr. Fombonne became a “psychiatrist / epidemiologist” and a consultant to the UK medical authorities on MMR vaccination and autism”

The Wakefield controversy began in 1998. So:

Fombonne, E. (1996). Is the prevalence of autism increasing? Journal
of Autism and Developmental Disorders, 6, 673–676.

Fombonne, E. (1997). The prevalence of autism and other pervasive
developmental disorders in the UK. Autism, 1, 227–229.

QED.

The author further asserts that:

“It is obviously customary to disclose sources of funding, Disclosing sources of “Non-Funding” on the other hand is unusual. In any case, it is nice to know that Dr. Fombonne’s research was never funded by the “Industry”.”

This is easily explainable in that Dr. Fombonne’s work has been informally criticized as being supported by the pharmaceutical industry, possibly with the intent that he would manipulate the data in favor of finding no association. This statement may have been given to help put such non-sense to rest.

Conclusion

It is important to remember that the weak criticisms in the critiques above do not remove the genuine and quality criticisms. The authors do point some genuine problems. The failure of both editor and Dr. Fombonne to make adequate response is also disagreeable.

By the same token some of the criticisms are remarkable for their lack of relevancy or factual basis. There are problems with these critiques that have a real potential to mislead others. It is to be hoped that the NAA and the authors will take steps to amend this, leaving their better criticisms intact.

Harold L Doherty – at it again

26 Feb

Harold Doherty last week built himself an army of strawmen in order to demoinse the neurodiversity movement. I and many people left comments that were never published so I wrote the above linked post to demonstrate to Mr Doherty how illogical, ill-thought out and just plain old wrong his points were. He never responded but it seems Mr Doherty is never one to let a little thing like accuracy cloud his opinions.

Today I see a post entitled ‘Is The Neurodiversity Movement Ashamed of Lower Functioning Autistic Persons?’ to which the short answer is ‘uhhh, no – whatever gave you that idea?’

Luckily Mr Doherty proceeds to tell us what gave him that idea. Strawmen ++

It seems at times that the Neurodiversity Movement is ashamed of the lower functioning members of the autism world. Autism is defined by the ND movement as simply another natural variation of human wiring.

No it isn’t. That is one _aspect_ of what autism is.

“Autistic intelligence” is defined as a different, perhaps even a superior form of intelligence.

Might be. There seems to be good evidence for extraordinary mental skills in some autistic people.

Doubt is cast on whether lower functioning autistic persons even exist by the more strident ND’ers.

Really? Where? Who says that?

Even autistic persons who have demonstrated no communication skills, engage in seriously and repetitively self injurious and dangerous behavior should not be treated or cured in the view of the ND movement.

Ditto. At some point Mr Doherty you’re going to have to start _providing some sources_ – all this alarmist arm waving is mildly entertaining but ultimately just silly and self defeating.

Recently CNN’s Dr. Gupta featured the story of Amanda Baggs, diagnosed as being a low functioning autistic person, but clearly very intelligent and, with the aid of technology, an excellent communicator. The implied message – even low functioning autistic persons are really quite intelligent and do not need a cure or treatment.

Nothing at all was implied. It seemed quite clear to me. Amanda does not need a cure. I believe she has had some treatments of mixed efficacy at various points in her life. Your implication seems to be – and feel free to turn up and correct me if I’m wrong – that silly old Amanda can’t possibly know what’s good for her and she can have no empathy with other low functioning autistic people, whereas the Great Mr Doherty knows all. He knows for example that silly old Amanda doesn’t know what’s good for her.

Unfortunately Dr. Gupta played into this denial of the existence of truly low functioning autistic persons by continuing a long history of media focus on autistic savants and other high functioning autistic persons while ignoring the sometimes brutal realities which confront low functioning, seriously disabled, autistic persons.

Yeah, or maybe we could discard the conspiracy theory and conclude that this particular piece wasn’t about that aspect of autism?

My autistic son, Conor, is a low functioning autistic person who brings me great joy. I delight in talking about how happy he makes me every single day. But, unlike members of the Neurodiversity I am not ashamed to admit the severe challenges he faces in life and I am not afraid to talk about them publicly.

I wonder how Conor feels about that and whether Mr Doherty would care?

Anyway, the point is that no one I know is ashamed to admit the severe challenges autistic people face in life. In fact, that’s kind of the point. To highlight these kind of things. Here I’ll say it in the plain English that I reserve exclusively for people incapable of appreciating shades of grey:

Autistic people face severe challenges in life. I am not ashamed to admit this publicly. I am however, afraid to talk about them publicly because when I did, various people who wanted to cure their kids were vicious about her. So now I and my wife talk about her in a private closed access blog which is open to friends and family only.

Unless such public discussion takes place there will be no improvements for Conor and other autistic persons like him. Of course that is exactly why the Neurodiversity movement attempts to censor such discussion.

I love accusations of censorship that come from men like Mr Doherty who actively censor their own blogs and refuse to participate in debate. Its always good for a chuckle.

I _think_ Mr Doherty is alluding to the revulsion some of us have for Autism Speaks and their one sided propaganda piece ‘Autism Every day’. We don’t want to censor it Mr Doherty. We (all 748 – so far – of us) want to expand it to truly reflect the reality of ‘Autism Every day’. Not just the self pity bits. If you don’t want these parts included then I think you need to carefully look at how that holds up against your accusations of censorship.

David Kirby’s Causation Trail

22 Feb

In a truly fascinating exchange on the Evidence of Harm Yahoo Group, David Kirby has revealed:

…the studies which, when taken together, suggest a plausible biological mechanism for mercury exposure as a contributing factor to regressive autism

The exchange came about as a ‘renegade’ poster to that group started laying down a smidgen of fact regarding the state of the science that props up the thiomersal hypothesis. S/he is not a popular bunny on that group.

The exchange led group big cheese Lenny Schafer to state:

It seems that junk science is in the eye of the beholder. It will probably take an impartial jury in a court of law to substantially settle if there is enough evidence of harm to implicate thimerosal and or vaccines in autism.

Seems like Lenny hasn’t been keeping up with the news in that regard.

Anyway, back to David Kirby. Hot on the heels of his amusing further goalpost shifting (somehow the non-decrease in autism numbers which, in 2005 and 2006 would be a grave blow to the thiomersal hypothesis are now suddenly nothing to trouble this teflon coated hypothesis) comes this – David Kirby’s statement on the existing studies which support mercury exposure (what? Not ‘MERCURY _IN VACCINES_ AND THE AUTISM EPIDEMIC: A MEDICAL CONTROVERSY’ David? Just any old mercury now is it? Bless you for exposing the courage of your convictions.)

So which studies float David’s boat? This is his list:

Richard Deth, Northeastern U;
Martha Herbert, Harvard U;
Jill James, Univ of Arkansas;
Thomas Burbacher, Univ of Washington;
Diana Vargas, Johns Hopkins;
Isaac Pessah, UC Davis;
Mady Hornig, Columbia U;
Mark Noble, Univ of Rochester.

Eight people, eight studies. Thise is the ‘science’ that David thinks suggest a plausible mechanism for mercury being a contributing factor for regressive autism.

As an amusing aside, don’t you love (and appreciate!) how careful David is becoming with his choice of words these days? No more of this ‘thiomersal causes autism’ stuff for him! Now its’mercury’ (not ‘MERCURY _IN VACCINES_ AND THE AUTISM EPIDEMIC: A MEDICAL CONTROVERSY’) and instead of ‘causing’ we have ‘contributing factor’ and instead of autism we now have ‘regressive autism’. best of all we have ‘suggest’ instead of MERCURY IN VACCINES AND THE AUTISM EPIDEMIC. Bless him, all the blog reading he’s been doing from the skeptical folks is finally paying off.

So, lets turn our attention to these studies of David’s. First of all we should note that the Mark Noble cite is a red herring (you lose skeptic points for that David) as, if I’m not mistaken, this study is a) a pilot study and b) not as yet underway. Certainly none of the other ten studies PubMed attributes to Noble, M. appear to discuss autism. Naughty naughty.

Richard Deth

Deth’s paper, if I may quote myself, can be summed up thusly:The basic gist of the Deth paper is that various toxins, including thimerosal, affect methionine synthase activity (a process that helps in building proteins) and that this can adversely affect children. In short, the Deth paper alleges that thimerosal causes methionine synthase dysfunction (MSD).

There are several issues with this as they relate to autism. Firstly, MSD and autism do not resemble each other. Symptoms of MSD are: Anemia, moderate to severe developmental delay, lethargy, anorexia, and homocystinuria (mental retardation, dislocation of the crystalline lens of the eye, sparse blond hair, and cardiovascular and skeletal deformities). Further issues:

1) There is no active transport mechanism into the central nervous system currently known for ethylmercury (thimerosal) whereas there is an known and active transport mechanism for methylmercury.
2) Because its half-life is much longer, methylmercury is more likely to accumulate than ethylmercury, causing higher levels of mercury in the blood.
3) Exposing cells in vitro to ethylmercury eliminates the most important difference between those two forms of mercury, and ignores the fact that ethylmercury is unlikely to enter the central nervous system at concentrations likely to be harmful.
4) The authors chose to use a cell line derived from a metastatic peripheral nervous system tumor to make predictions about developing healthy cells of the central nervous system. If the authors were interested in making claims about the developing central nervous system they should use cells derived from there.
5) The authors make statements in their introduction about developmental disorders such as fetal alcohol syndrome, Rhett’s syndrome, or Fragile-X syndrome, they fail to consider the fact that all of these diseases have their origins in the developing embryo and fetus, not postnatally.
6) The authors’ reference a study that evaluated the causal association between thimerosal and vaccines using the Vaccine Adverse Events Reporting System (VAERS). Remember how good VAERS is?

Bart Cubbins produced a video detailing similar points.

Martha Herbert and Dianne Vargas

These two papers independeintly of each other indicated a role for neuroinflammation in autism (<a href="http://www.generationrescue.org/pdf/herbert.pdf&quot; rel="nofollow"Herbert here and Vargas here but they differ slightly. The Vargas paper states:

neuroinflammatory process appears to be associated with an ongoing and chronic mechanism of CNS dysfunction

and leaves it at that. Herbert specualtes with no basis regarding the fact that metals might play a part in the neuroinflammation. She has no basis for these speculations and it surprises me that they’re in a paper published in such a good journal.

Jill James

Jill James’s studies revolve around glutathione. Glutathione, amongst other things, removes merucry from the human body. James’ studies purport to show that autistic people are deficient in Glutathione and thus when they get mercury they can’t excrete it in the same way non-autistic people do.

However, they don’t. James tried to show that the two types of Glutathione in the body (what she called Active and Inactive) were about 31% (Active) and 33% (Inactive) less in autistic kids than non-autistic kids. However, it should be noted that these are not two differing forms of Glutathione but instead two states of one thing which have a relationship to each other – when one goes up, the other goes down. As Not Mercury states:

Decreased synthetic capability is one possible explanation but this would probably result in a significant deficit of total glutathione not an imbalance between the two oxidation states. _If James found any evidence of impaired glutathione synthesis in this small group of children it wasn’t included in any of her published work_. It doesn’t sound like the children were suffering from a glutathione deficiency as much as an increased oxidative burden greater than the capacity to recycle and glutathione and maintain full oxidative defense capacity.

No deficiency in Glutathione. But Not Mercury takes it a step further:

let’s suppose children with autism had significantly lower levels of glutathione. Would it render them unable to detoxify thimerosal from vaccines? Probably not.

The average human carries about 6milligrams mercury, even if James’ figures were accurate (which they are clearly not) or represent what she claims they do (which they clearly don’t) then the human body would still have several million times more glutathione than needed to excrete the suspect mercury. As Not Mercury says:

A person so severely deficient in glutathione they would be unable to detoxify 250 micrograms of mercury (upper limit of thiomersal in vaccines 5 years ago) probably wouldn’t survive long enough to be vaccinated in the first place. Every breath of air would expose them to lethal levels of ozone, pollutants and other oxidants.

Please read all of Not Mercury’s piece. It’s an eye opener.

Thomas Burbacher

This paper reached one conclusion.

The key findings of the current study are the differences in the disposition kinetics and demethylation rates of thimerosal and MeHg. Consequently, MeHg is not a suitable reference for risk assessment from exposure to thimerosal derived Hg. Knowledge of the biotransformation of thimerosal, the chemical identity of the Hg-containing species in the blood and brain, and the neurotoxic potential of intact thimerosal and its various biotransformation products, including ethylmercury are urgently needed to afford a meaningful interpretation of the potential developmental effects of immunization with thimerosal-containing vaccines in newborns and infants. This information is critical if we are to respond to public concerns regarding the safety of childhood immunizations

In other words, Burbacher blood vs brain is not a valid comparison and that methHG vs ethHG is not valid either. He then goes on to state that more research is needed into what the toxic effects of thimerosal might be. He states that mercury from vaccines doesn’t accumulate as much in blood as it does in the brain and thusly, using blood levels of mercury to represent brain levels of mercury is innacurate.

It was also presented that this paper connected the dots between thiomersal and neuroinflammation (see Herbert and Vargas) but this is a false representation and not claimed or even insinuated by Burbacher.

Two more issues arose from this paper. Firstly, when the Burbacher team performed the extraction of mercury from the blood or brain matter, they failed to introduce controls to ensure that the thimerosal was not degraded in any way as a result of the extraction process. This means they had to basically assume from the resultant possibly contaminated material how much was attributable to methylmercury and how much to thimerosal (ethylmercury). Secondly, Burbacher used thimerosal free vaccines and added pure thimerosal. It is difficult to know how this fresh preparation compares with vaccine formulas when thimerosal is part of the manufacturing process and may have suffered some degradation to inorganic Hg in the vials before administration.

Issac Pessah

The Pessah paper related how the study team found that thiomersal administered to mice caused “dendritic cells” damage. Specifically:

the thimerosal disrupted the normal biological signals that take place in cells, Pessah said. At lower concentrations, the signal disruption caused an inflammatory response; at higher concentrations it caused cell death.

So the position here is that thimerosal has a negative effect on the immune system. Lots of parents think autism is immune-system related. However, this study is a) unreplicated (as far as I know) and b) we may be overestmating the real world effect. Here’s Autism Diva talking about hearing Pessah on Autism One radio.

But the really weird thing is how he described how long the effect would last when the dendritic cells came into contact with mercury. If Autism Diva understood him correctly, lets say a kid gets injected with a vaccine containing thimerosal and the dendritic cells that come into contact with the thimerosal. This is not necessarily all the dendritic cells–some of them, and the DCs are affected by the thimerosal, depending on how much thimerosal they come into contact with. And this effect lasts…. years and years? Is that what he said? No.

Was it months and months? Is that what he said? Maybe it was days and days? Hours and hours? No, actually, what he said, if Autism Diva heard him correctly, was “minutes and minutes.”

So, we know that if you take dendritic cells of a particular kind out of a mouse, and grow them in a glass dish and dump a weak solution of thimerosal on them, they freak out or get a little weird and either way can’t do their job normally, and this effect lasts for,

(gasp)

minutes and minutes.

And speaking of Autism Diva we come around to:

Mady Hornig

Briefly, Mady Horning conducted a study wherein she claimed to have developed a mouse model for autism which she then used to test how the model responded to the introduction of thiomersal. According to Hornig, the study showed that:

1. The mice they used are a good model for autistic people
2. The ‘vaccine’ schedule they used successfully mimicks childhood immunization programs
3. That the outcomes from Auto-immune disease sensitive mice were consistent with autism
4. That this indicates a genetically influenced sensitivity to thimerosal in autistic people

Autism Diva took this study apart when she pointed out that:

Did Dr. Hornig and colleagues find these features [diagnostic criteria for autism] in the ‘SJL Thim” mice?’ No.

Prometheus also had reservations about the design of the study:

So, the human experiences a maximum blood level of 1.63 (arbitrary units) and the mouse – since it is being dosed at a smaller fraction of its half-life – sees a maximum blood level of 2.61. In short, the mouse gets to a blood level 60% higher than the human……I found myself wondering, “Why didn’t they use the 50th percentile (50% weigh more than this weight, 50% weigh less – sort of an ‘average weight’)?” I have no answer – but I have an idea. By using the 10th percentile, they were able to give the baby mice an even bigger dose of mercury……So, by using the 10th percentile weights, the authors were able to give the mice about 15% more thimerosal. This goes nicely with the dosing schedule to significantly raise the dose the mice receive.

One of the big talking points from this study was reported by David Kirby in Evidence of Harm:

… putting up a photo of two mice. “He has groomed through the skull, and eventually destroys his partner,” Hornig said. Every parent of an autistic kid in the room could be seen grimacing in dark recognition of such destructive behavior.”(page 312)

Uh-huh, or maybe they were just grimacing as its not nice looking at mice chewing through the skulls of other mice?

Anyway, hyperbole aside, why did Hornig choose those particular mice? Here’s what else Autism Diva found out.

Why did Hornig pick the SJL/J mice in particular?….Besides being an “autoimmune disease-sensitive” breed what else is known about the SJL/J mice?

Good question. Diva found the answer highly revealing:

Behavior
1. High spontaneous fighting….
2. Severe fighting among males housed together, beginning at about 8 weeks.
3. Most males will be killed by 4-5 months unless caged separately….

Diva also found a separate source that showed that:

…some breeds do a kind of agressive grooming of other mice called, “barbering”

So, it seems that Hornig sourced a set of mice known to be aggressive, she then systematically overdosed them and then reported the fact that this aggression was indicative of autism. Right.

Wrapping It Up

A study that hasn’t yet been done. A study that alleges something it can’t back up. A study with no data and empty conclusions. Two studies that have nothing discernable to do with heavy metals. A study that shows ethylmercury and methylmercury are not comparable. A study that damages cells taken from a mouse for the span of minutes and a study that purposefully overdosed mice known to be aggressive.

Lets remind ourselves of the Judge;s opinion of this same body of science when it was presented by Dr Geier in the RhoGAM hearings as support for the view that thiomersal causes autism:

…the Court notes that, in fact, a literature review can be an appropriate part of a method of determining general causation. However, a literature review must still be performed appropriately. As revealed by his testimony at the Daubert hearing, Dr. Geier, however, relied upon a number of disparate and unconnected studies, including the findings of Dr. Haley and Dr. Lucier, to reach a piecemeal conclusion with respect to general causation…..However, upon being subjected to extensive cross examination, much of Dr. Geier’s analysis, based upon his collective review of a motley assortment of diverse literature, proved, in the Court’s view, to be overstated.
