Dr. Johnson testifies in the Autism Omnibus Hearing

24 May

Dr. Johnson’s testimony was fabulous and I think it’s safe to say that it wreaks more devastation on the petitioners'(the parents) case. As of this moment, I can’t give you a lot of detail about Dr. Johnson’s qualifications, unfortunately. For some reason a portion of the audio recording (MP3) that would have included Dr. Johnson’s statement of his qualifications is missing.

One thing I think is important to point out here is that the respondents experts’ (written) reports, and even the list of the respondents’ experts has not been posted to the Autism Omnibus docket. The parents’ lawyers (the Petitioners Steering Committee, or PSC) do have their experts list posted to the docket. Some time ago (I think it was more than a year ago) the Department of Justice attorneys asked the Special Master if the Federal Court would refrain from posting the lists of the respondent’s experts for fear that their experts would be subjected to harassment. That request doesn’t seem to be on the docket now, but it used to be. It’s likely that after the experts were listed the first time the experts for the government were harassed. This would be in keeping with the way different experts, and even parents such as myself and Kevin Leitch and others, have been harassed by “mercury parents” or their friends. You can see from the Autism Omnibus Proceedings Docket Here: http://www.uscfc.uscourts.gov/node/2718 that the there are no more postings of lists of respondents’ experts after mid 2006. There’s an entry from March of 2007 that is called, “Respondent’s Notice of Expert Witnesses,” but there’s no document now linked to that entry.

The point I’m trying to make about the missing expert list is: I can’t pull up the list of expert witnesses for the respondents (the US government, essentially) for this hearing because it’s not available. So I can’t find out easily who Dr. Johnson is, though he is a professor at university, and has a lab, and has published on neurophyisology and neurodegenerative diseases, and he uses tissue slides and tissue cultures. Worse, “Johnson” is a very common name so if you go looking for experts named Johnson who publish in neurodegenerative diseases, you’ll find 3 or 4 of them in pubmed. The DoJ lawyer here is one of Mr. Matanoski’s team of attorneys. As far as I can tell the junior attorneys on the team are Bo (Beau?) Johnson, Ms. Ricciardella, Ms. Renzi and Ms. Espinoza (Espinosa?).

I don’t know which lawyer is examining Dr. Johnson. From her voice, I’m guessing (again) that it’s Ms. Renzi. Again this is my transcribing of what was said, some of it is word for word, some of it is a close paraphrase of what was said you can find the following somewhere around 8 minutes 43 seconds on the second MP3 file from Day 7 (May 20). Here is some of the very interesting testimony from Dr. Johnson:

Ms. Renzi: Dr. Deth cited a paper by Mady Hornig in support of his arguments. You mentioned that the mouse strain Dr. Hornig used was selected because it had a stronger immune response, but took issue with Dr. Deth’s explanation of the rationale behind the use of the strain. … Deth said hers was a mouse strain harboring genetic deficits in redox related enzymes… What strain of mouse was used?

Dr. Johnson: It was an SJL-J mouse. (Dr. Deth) was inferring that there was a redox enzyme differential, or some kind of differential (in this strain) and that’s absolutely not true. The mice have a this increased immune response and that’s why they were selected. … There’s absolutely no data supporting the fact that there is a redox enzyme differential. Now I can understand the reason that it’s in there because it supports his hypothesis… but it’s not an accurate representation of these mice.

Renzi: Do you have confidence in Dr. Hornig’s reported results?

Johnson: Uh, no.

Renzi: Part of that has to do with the hippocampal sections, correct?

Johnson: The quality of the images,… I’ll point this out, (the sections from the Hornig paper) .. What you can see is when you look at these images–to me these images are absolutely awful, now the staining here is hematoxylin and eosin, and it’s supposed to stain for architecture and cell integrity and a variety of other things. The pictures are diffuse, there’s no clear neuronal fields. Right here there is weak staining. … If you look here, the cells that are dark right there, those are the neuronal fields. The quality is just extremely low. … Quality of the sections themselves are low. … Let’s put it this way, I’ve seen this in my lab before. I’ve seen people come to me with sections stained like this. I’ll say: Something’s wrong. OK? The tissue wasn’t prepared right. There’s something definately wrong here. Because these do not maintain the nice cellular architecture that you should see if the experiment is done right and the tissue is harvested correctly.

Renzi: Problems with these slides led you to doubt the findings of the Hornig paper? Has a recent paper contradicted Hornig’s findings? …

Johnson: The… comparable fields in the Berman paper. To me they are absolutely beautiful. … It looks very, very, very good.

Renzi: … What dose of thimerosal was used in the Berman paper?

Johnson: …They also used a does that was 10 times higher…

Renzi: Did both studies (stain with antibodies)?

Johnson: There is a distinct difference between Berman and Hornig studies’ slides… If you look at the architecture of the tissue in the Berman study…. (there is) nice staining in the hippocampus….

Special Master:… (interrupt for clarification)

Johnson: … Berman sections are the two sections on the left side… What you can see is there’s very nice staining in the field, the neuronal field are not staining intensely (which is what they are expected to show)

Now if you look at the upper 4 panels on the right side these are from the similar panels from the Hornig study. The first thing that I want to point out is that if you look at the tissue, it’s full of holes… Look at this enhanced image right here, the bottom two panels C and D from the Hornig. You can see that the tissue almost looks like it’s disintegrating, It’s breaking down. There’s holes all over in the tissue.

I know from experience when you see tissue like this the amount of nonspecific staining by antibodies could be intense.

Basically, if someone came to me with this kind of staining in my laboratory I would say to go back and do the whole experiment again,… I would not want… for one these are unpublishable to me, and two the potential for artifactual data to be generated from this kind of (poor quality tissue) is extremely high. … This is very important. You know, you can do whatever you want after you’ve got the tissue, but it’s the process of getting the tissue so that the quality is extremely good. You need to start with high quality tissue.

… The Berman tissue was absolutely perfect. … The sections are beautiful.

One thing I took away from Dr. Johnson’s testimony is that there’s no way that the Hornig paper should

have made it past a competent peer review and into a “peer reviewed” publication. The Hornig paper has a few other problems that have been discussed before, but these problems never been reported in into a letter to the journal that published that paper, Molecular Psychology, as they should have. (Click here to download a copy of that paper from the SAFE MINDS website.)

Hornig wrote that paper with her main squeeze, Ian Lipkin, and with David Chian. This research was funded by the UC Davis MIND Institute, SAFE MINDS and by part of an NIH grant of Ian Lipkin’s. Surely someone knew how bad those tissue slides were even before it was submitted to the journal. Surely someone at the journal should have had a person with some kind of expertise review the article. Surely in 2004 some person with expertise would have noticed the problems with the degraded and uninterpretable tissue slides in the Hornig paper. I didn’t notice any problems with the slides when I read the paper because I don’t know what stained tissue of mouse hippocampus is supposed to look like and neither would most of the mercury parents who have tried to use this paper to show that their own child was made autistic by vaccines containing thimerosal.

The MIND Institute scientists must have seen the problems with Mady Hornig’s study, but they invited her to come speak about her thimerosal-causes-susceptible-mice-to-become-mindlessly-violent-killers hypothesis at the conference I call the “MIND’s mini-DAN!”. Video of her speaking at that conference is still available on the MIND’s website here: http://www.ucdmc.ucdavis.edu/mindinstitute/events/toxicology_recorded_events.html

And you can see video of John Green speaking there, too. He was described in the most glowing terms by Dr. Robert Hendren. Maybe Dr. Hendren didn’t know about the “earthworm eggs” and “fecal implantation enemas” that Dr. Green had prescribed to some of his patients. After Green spoke, Dr. Hendren knew about the problems with Green’s citing of a provoked urine toxic heavy metals lab result from Doctor’s Data Inc that was in Dr. Green’s slides, because I told Dr. Hendren about the problem with that lab report. As far as I could tell, Dr. Hendren wasn’t particularly worried about that. The video of Dr. Green “explaining” what that lab test meant to him is still on the MIND’s website. I have a problem with that, since parents can watch those videos and make poor treatment decisions for their children based on them. On the other hand, those videos seem to stand as a testimony to something less than scientific that seems to be going on at the MIND Institute. To UC Davis’ credit however, the Berman (2008) study that totally contradicts the Hornig (2004) study was also conducted at UCD.

Dr. Johnson has plenty of interesting things to say about Dr. Richard Deth and his neuroblastoma cell line experiments. Apparently, Dr. Deth will be back to testify again in the autism omnibus. Perhaps he will explain why he seemed to cut his experiments short (time-wise) and why he called neuroblastoma cells “neronal cells” when they should not be called neuronal cells, and why he didn’t show critically important “dose response curves”.credit: taminsea

I may have to devote a separate post to the issue of Deth taking data from (but not citing) a 1958 paper (pdf) that reported the level of cystathionine in duck brains (besides duck, also, human, cat, rat, guinea pig, horseshoe crab, chicken, cow and monkey).

Autism Omnibus – Liz Mumper

21 May

Elizabeth Mumper is an expert witness for the Petitioners (for the families). She is the medical director for DAN/ARI and founder of the Rimland Centre.

She firmly believes vaccines cause autism.

On Days four and five last week, Mumper testified. Again, there’s little point me going through the Petitioners exam – you can easily guess the content. Where things got interesting was on cross exam.

Again, this is me making notes on the audio so there may be minor errors. I also didn’t get the name of the young man doing the cross exam for the Dept of Justice.

In the expert reports that Mumper prepared for the thiomersal hearings, she stated:

1 in 6 children born today is predicted to have blood levels of mercury high enough to impair neurological development.

And she referenced Stern, 2005 to support that statement.

The DoJ immediately asked her where in the Stern paper that figure was quoted. After 2mins, 01 seconds of which only the noise of someone rifling through a paper could be heard, Mumper stated:

I do not see the 1 in 6 statistic there.

To which the DoJ lawyer asked:

Q: So the Stern paper does not state ‘1 in 6 children born today is predicted to have blood levels of mercury high enough to impair neurological development.’

A: You are correct.

Ouch.

The next question that came Mumpers way was – in fact I’ll do the whole exchange:

Q: Have you ever treated a child for mercury poisoning?

A: No.

Q: What formal training have you received in toxicology?

A: None.

Now wait just a minute – Liz Mumper, medical director of DAN! is stating that _she has never treated a child for acute mercury poisoning???_ Did I miss something here?

There was a lengthy to and fro after this during which ‘autism: a novel form of mercury poisoning‘ was discussed. Mumper squirmed a bit but admitted that it was published by three non-scientists, in a non-peer reviewed journal and that as she put it ‘the science had progressed’ since its publication (which was her way of saying it was dead wrong I think).

The DoJ moved on to a discussion of some of the papers that Mumper used to support her beliefs. Key amongst them were Mady Hornig’s Rain Mouse study and the Nataf Porphyrin study.

Mumpers take on the Hornig paper was fascinating. According to her, the:

…mice got OCD behaviours and they clawed through each others skull…

Now firstly – OCD behaviours? According to every member of the mercury militia worth their salt, Mady’s mice got _autistic_ behaviours. Now, obviously, they didn’t. Everyone from the IOM down (including certain tiara wearing bloggers) pointed out that the behaviours reported by Hornig bore no resemblance to autism. Now here was Mumper confirming that.

Secondly – this skull clawing – why was that raised in court? This behaviour was certainly not part of Hornig’s paper. It smacks of second hand sensationalism.

The DoJ lawyer asked Mumper what her opinion was of the Berman paper that entirely refuted Hornig (‘the present results do not indicate pervasive developmental neurotoxicity following vaccine-level thimerosal injections in SJL mice, and provide little if any support for the hypothesis that thimerosal exposure contributes to the etiology of neurodevelopmental disorders’).

Amazingly, Mumper’s response was that she hadn’t read it! I must admit that when she said that (and yes, you could clearly hear the embarrassment in her voice when she admitted that) I laughed out loud. Aren’t medical directors supposed to keep up to date with science relevant to their ‘areas of expertise’?

The next section concerned the role of the ‘new kid on the black’ – Porphyrins. I’ll quote the initial exchange as near to verbatim as I can.

Q: You order this Porphyrin test in your own practice?

A: Yes.

Q: And do you find them to be a reliable measure of mercury toxicity in autistic patients?

A: *I’m split on that now* because I think that they’re good at showing differential toxicities but the thing that is worrying us now is that we’ve not looked at a lot of control children and we’re starting to do that and *finding that some normal children have abnormal Porphyrins too* .

Again, to those of us who’ve been following these stories, this is not news. However, what _is_ news is to hear the medical director of DAN/ARI confirm that Porphyrins aren’t as useful as touted. Note that although she knows she’s getting false positives she’s still ordering the tests.

There was some back and forth at that point as to why Mumper thought that the Porphyrin test wasn’t very accurate. She says she thinks it is because the control in the Nataf paper were French and Swiss and that US kids are ‘environmentally and genetically different’.

Could be. But, as Prometheus pointed out when we talked about this via email:

Now, if Swiss and French kids are “…too genetically different…” from US (and presumably UK) children for something as simple (and reportedly reliable) as the “porphyrin profile” to work, then what about the Amish?

Which is an excellent point. Its an established fact that the Amish _are_ genetically different. They’re also certainly environmentally different. I guess that doesn’t matter though.

DoJ wrapped up day four by asking:

Q: Porphyrins do not provide any evidence that mercury is in the brain, is that correct?

A: That’s correct.

On day five, DoJ played a little dirty. Bearing in mind that Mumper had said on day four that she was ‘split’ on the efficacy of the Porphyrin test, DoJ asked her to read out sworn testimony she had given in a separate case in Jan/Aug 2007:

Probably the most helpful test to me now is the Porphyrin test….

Which direct contradiction of yesterdays testimony was embarrassing enough, but she then went on to say (in 2007) that:

….it actually looked at the impact of ethyl mercury….

When on day four she had testified that it did no such thing.

All in all, DoJ made Mumper look very unsure. They tripped her up factually any number of times and led her into making statements (never treated mercury poisoning!) that I’m pretty sure she would not really have wanted to make.

Laura Hewitson’s Stinker

18 May

Sorry about the title, I couldn’t find a word to rhyme with her last name to infer wrong-doing a la Age of Autism’s ‘Grinker’s Stinker. Anyway….

Meet Laura Hewitson. Laura is the lead and joint author of a trio of papers presented at this years IMFAR as posters.

These papers (also shredded by Orac) purport to show how it is possible to mimic the 1999 US vaccine schedule and give monkeys autism as a reult. Never mind the fact that the results reported don’t sound or present anything like autism (<em>”survival reflexes, tests of color discrimination and reversal, and learning sets”</em> huh??), lets look at Laura Hewitson a bit more closely then I managed to in a quick 10 min post last time.

As I mentioned at the time, Laura Hewitson claims affiliation with DAN! Thats enough in my book to place a rather large red flag against her impartiality.

Now I’ve learnt that her entanglement with the vaccine/autism hypotheses goes very much further than that.

It turns out that Hewitson’s partner is Dan Hollenbeck, an Age of Autism contributor. Hollenbeck owns the website FightingAutism.org and in the top right hand corner of the FightingAutism website are the words:

FightingAutism is now part of Thoughtful House Center for Children.

And we all know who is the big cheese at THoughtful House don’t we? That’s right – one Andrew Wakefield. He’s also the co-author to the three studies poster presented at IMFAR.

Hollenbeck’s asociation with Thoughtful House goes beyond just having a website affiliated with them however. He’s also an employee of Thoughtful House.

Director of Information Technology for Thoughtful House, Dan Hollenbeck received his Bachelor of Science degree in Electrical and Computer Engineering from the University of Wisconsin-Madison in 1992

….

When their son was diagnosed with autism in 2001, the Hollenbecks relocated from Oregon to Pittsburgh in order to accept employment as an Information Technology Manager for a large NIH (National Institutes of Health)-funded medical research organization

….

He is also on the Board of Directors, as well as the Research Committee, for SafeMinds…

So, here we are with three poster presentations from a woman who has an autistic son, affiliated with DAN!, is married to the Thoughtful House IT guy (who also happens to be on the Board of Directors of SafeMinds) and these afore-mentioned poster presentations are also co-authored by Andrew Wakefield.

I wonder just how impartial this science can be?

How about when we throw one more fact into the equation?

437. Laura Hewiston (sic) and Dan Hollenbeck on behalf of Joshua Hollenbeck, Dallas, Texas, Court of Federal Claims Number 03-1166V

That’s right. Hewitson and Hollenbeck are suing HHS for vaccine injury visited upon their son Joshua.

Now, lets turn our attention to IMFAR where Hewitson made her three poster presentations. INSAR have regulations governing the papers and abstracts submitted.

INSAR requires authors to disclose their sources of contributed support (commercial, public, or private foundation grants, and off-label use of drugs, if any). INSAR also requires authors to signify whether there may be a real or perceived conflict of interest. Any potential for financial gain that may be derived from reported work may constitute a potential conflict of interest.”

Now, maybe Hewitson did note the fact that:

a) Her husband is an employee of an organisation that makes money from treating what they allege is vaccine caused autism.

b) She has an autistic child.

c) Said child has been registered for compensation for alleged vaccine damage resulting in autism (I assume they’re part of the Omnibus proceedings then?)

But if she did, then it isn’t recorded in the abstracts posted on the Age of Autism website.

Autism Omnibus – Vas Aposhian

16 May

Vas Aposhian is – like Sander Greenland – an expert witness for petitioners (the families) and a professor of molecular and cellular biology as well as a professor of pharmacology.

On Day 2 and 3 he testified as to what seemed to be the main hypothesis behind the whole thiomersal/autism idea.

The basic idea is that some people are genetically predisposed to something called _mercury efflux disorder_ (plain english, they can’t get rid of mercury as well as most people can, it crosses the blood brain barrier and triggers autism). Mercury Efflux Disorder is itself an unproven hypothesis but Aposhian passionately believes in it.

He came under heavy cross exam (I won’t go through his performance whilst testifying to his own ‘side’ – we all know the basic hypothesis), that compromised a lot of day two and most of the morning of day three (the audio is released slowly so I’m a couple of days behind). The part I’m writing about today starts about an hour and a half into day three (NB: I’ve downloaded all the MP3’s and stitched them into one file).

Aposhian says that the mercury efflux hypothesis is supported by six papers:

…each piece of evidence alone leaves some doubt but taken all together the evidence implicates thimerosal/ethylmercury as the likely precipitating agent in the etiology of some of the autism spectral disorders.

Respondent counsel referred to these six papers as ‘pillars’ supporting the hypothesis. Aposhians’s pillars are:

First, Adams et al. (2007) demonstrated that teeth from autistic children contain more mercury than those from non-autistic children.

Respondent counsel asked Asphosian what he thought he could criticize about these papers he says ‘implicate thiomersal’. Regarding Adams et al, Asphosian said (and I’m paraphrasing slightly after scribbling notes furiously):

1) The number of controls should’ve been increased.
2) There were too few test subjects
3) When asked if raised mercury level was an indicator of toxicity, Asphosian answered “I don’t know”.
4) When asked if he would’ve expected mercury concentrations to vary depending on gender, Asphosian answered “Yes”.
5) When asked if Adams controlled for gender Asphosian answered, “No, he doesn’t control for gender”.
6) When asked if lead concentration of a tooth affected mercury concentration of a tooth, Asphosian answered, “I don’t know”.
7) Asphosian was asked, given the fact that the thiomersal hypothesis depended on the role of _ethyl_ mercury, what type of mercury did Adams et al measure in the teeth? Asphosian’s answer was “…did not do speciation” – in other words, he didn’t separate the types of mercury out. He recorded it all.
8) When asked if mercury levels in teeth tell you anything about amounts of mercury in the brain Asphosian replied that he didn’t know as no one had ever done that study.

These are fairly damning failings in what Asphosian’s assumptions were regarding the quality of that study. Of course, there is more wrong with the Adams paper than just the above, but these points are pretty damning. The failure to control for gender, the paucity of subjects and the fact Adams et al didn’t concentrate on ethyl-mercury raise serious questions over what exactly this study can add to the so-called Mercury Efflux Disorder.

I’ll keep appending to this post as I work through the rest of the audio.

No such thing as a genetic epidemic

15 May

Since the Autism Omnibus started up again, I’ve been talking about how the Petitioners have pulled the tablecloth out from under the feet of the mercury militia. Its been a mainstay of the militia that there has been an epidemic of autism since the early 1990’s, caused by vaccines, most notably thiomersal and MMR (hence the strapline of mercury militia bible Evidence of Harm – Mercury in Vaccines and the Autism Epidemic and the ‘M’ in SafeMinds (Sensible Action For Ending Mercury -Induced Neurological Disorders).

In fact, lets be clear, SafeMinds believe in an Autism Epidemic, Generation Rescue believe in an Autism Epidemic, the NAA believe in an Autism Epidemic, Jenny McCarthy believes in an Autism Epidemic.

And yet this week, we had petitioners expert witness (i.e. _for the families_) in the autism omnibus destroying the idea of an epidemic. According to him, the number of children throughout the 1990’s/early noughties was in the hundreds.

That’s ‘hundreds’ from a population of 40 million.

He went on to say:

Q: So if the risk is confined to that group, clearly regressive autism, are you assuming then that there is no elevated risk to any other group – any other cases of autism?

A: In the calculations I made, yes.

This is a deliberate strategy on behalf on Petitioners. They want to destroy the idea that all the epidemiological evidence regarding autism and vaccines has shown thus far – that there is no association between autism and any vaccine. They cannot challenge the quality of the science itself so they have moved the goal posts. They are now saying _not_ that vaccines cause autism, but that _some_ vaccines _may_ cause autism in a population of children so tiny it cannot be detected by epidemiology.

That is in direct opposition to the very idea of an autism epidemic which, by definition, must be large and ‘unmissable’ – a tsunami of autism.

Amusingly, the beloved science editor of the Age of Autism blog decided the best way to deal with _his own sides_ expert testimony was to pretend it had never happened.

‘You cannot have a genetic epidemic’ – that’s another mainstay of the mercury militia. The idea that there has been an epidemic is used to support the idea that genes play a small, negligible role in autism (if they play a role at all) because ‘you cannot have a genetic epidemic’ and as we all know there has been au autism epidemic right? Therefore, genees can’t have played any role _in_ that epidemic.

Except that the families in the Autism Omnibus are now relying almost totally on the idea that there never _was_ an autism epidemic.

The genetic role in autism science came to the fore again yesterday when Yale announced a new study that found Genetic links to impaired social behavior in autism:

With the help of Yale’s Autism Center of Excellence, led by Drs. Ami Klin and Fred Volkmar, and many families of individuals with ASD, we have registered a possible association between some of the genes identified in animal studies as controlling affiliative behaviors in ASD.” The strongest statistical findings of the study implicate the prolactin gene, the prolactin receptor gene, and the oxytocin receptor gene in these affiliative behavior deficits.

I haven’t read the paper yet (and I’ll probably need help to understand all the highly technical gene talk) but I’ll probably have nore to say once I have. For now, its interesting that in the week that expert witness for the families in the Autism Omnibus gutted the epidemic hypothesis, yet another study was released linking genes to autism.

Autism Omnibus – Petitioners suggest new prevalence

14 May

As noted by Ms Clark yesterday, petitioners in the current Autism Omnibus hearing are redefining the terms of the so called ‘epidemic’ to proportions that would’ve been unthinkable to any card-carrying mercury militia member at the start of this year.

And as I noted yesterday, not only is the ‘epidemic’ (so long a standard of the vaccine hypotheses) being seriously watered down, so is the very definition of who can claim status as a member of the vaccine-induced-autism club.

And this is not as a result of any utterance by anybody on respondents (HHS) side – this is all direct from the mouths of the Petitioners legal team and their experts. Truly amazing.

The audio files were posted yesterday (please note that despite everything being linked, as of right now, only Day 1 audio files are actually present for download) so I could finally hear some of what was being said for myself. I haven’t listened to the whole thing yet but I wanted to hear more about what I posted yesterday – the fact that Petitioners are now claiming that thiomersal induced autism (assuming it exists at all) accounts for such a small proportion of autism that it is not detectable using epidemiology.

Dr Greenland says (and this is all on Day 1 File 1 – I ain’t going to transcribe it exactly!) that the figures Petitioners are talking about represent a sub-group of regressive autism he terms ‘clearly regressive autism’ (this is also mentioned in his report which I linked to in the post I made yesterday). And of course regressive autism itself is a sub group of autism. According to Greenland, the figures are:

Regressive autism: 28% of autism1.
Clearly regressive autism: 20% of regressive autism
Therefore, clearly regressive autism: (approx) 6% of autism

Now, when we translate this to what the vaccine hypothesis believers like to call ‘proper’ autism (by which I assume they mean classic/low functioning) we get this:

Classical/LF autism: 33% of ASD (based on Fombonne data again).
So, ‘clearly regressive autism’ is 6% of 33% of ASD.

Or in other words, Petitioners ‘clearly regressive autism’ accounts for approx 2% of all ASD.

I can’t say it often enough. This is the expert report of an expert testifying for petitioners. Amazing.

And lets also bear in mind that Greenland is not claiming that *all* ‘clearly regressive autism’ cases are caused by thiomersal. He’s saying that this is the numerical size of the group Petitioners claim *contain* those injured by vaccines, resulting in autism.

So, when we translate that to actual numbers what do we get?

According to CDC, we can estimate that 560,000 children (0 – 21) have an ASD. Using Greenland’s data we can see that:

2% of 560000 = 11,200 people aged between 0 and 21 have ‘clearly regressive autism’.

Based on the data on the front page of census.gov, there are 304,079,911 American citizens as of right now. The child population of which is 25% or 76,019,961.5.

Therefore, according to Petitioners expert witness, the ‘clearly regressive autism’ (aka autism-caused-by-thiomersal) population percentage of the US is *0.015%*.

Tsunami? Hardly.

1] interesting point to note – this is based on Fombonne’s work. Who would’ve thought we’d ever see Fombonne’s data being used to support Petitioners?

PS – maths is not my strong point. Feel free to double check and point out errors/fixes.

Thimerosal on trial- the incredible shrinking epidemic

13 May

The audio recordings of the first day of the thimerosal-only portion of the Autism Omnibus Proceedings hearings are now available here: ftp://autism.uscfc.uscourts.gov/autism/thimerosal.html. They are mp3 files.

Here’s some of what I heard yesterday via telephone and comments on what I think the parents’ lawyers seem to be implying now, maybe you will listen to the same discussion and take away different key points:

A lawyer for the petitioners (Mr. Williams, I think) said, as if a fact: there has been an autism epidemic, and he added that there is no such thing as a “genetic epidemic”.

They know this because no one could “miss” regressive autism in the past. I guess they might have missed other non-regressive autism and other ASDs.

The only kind of regressive autism they are interested in is the “clearly regressive” subtype, which they seem to be saying is about 2% or less of all ASD children born during the 1990s.

Apparently, they are only interested in the children of the “epidemic” era when kids got more thimerosal exposure.

There are so few of their target group that when these kids started to be “added” to the “epidemic” no one could see it happening, and likewise when the exposure to thimerosal dropped of precipitously, even though the numbers of these target group kids must have dropped off precipitously, no one could see that change in the larger epidemiological data.

So the epidemic might continue but it has nothing to do with thimerosal exposure now.

The numbers of “clearly regressive” autistics, however should be obviously diminishing. Because it’s a small group and not all of them “clearly regressed” following a vaccine containing thimerosal. These supposedly thimerosal-damaged clearly regressive kids must be disappearing by now, but maybe they’ve been replaced by kids who “clearly regress” due to another actionable agent. If they regress because of an non-actionable agent, like, say, oxygen or exposure prenatally to mom’s immune system, no one cares. Then logically, if all of the “clear regressing” autistics were caused to regress only by thimerosal, then there should be very few, or none, younger “clearly regressed” autistics in areas where thimerosal is not used for toddler age vaccines now and hasn’t been used in the past few years.

Apparently, they are claiming that thimeosal in vaccines only causes a subset of regressive autism, not including early-onset autism. So apparently there’s no way for a baby who got the birth dose of Hep B to be made autistic, since it can’t “clearly regress” shortly after birth. And if the baby only got the Hep B dose (if preserved by thimerosal), that alone couldn’t cause a regression months later. I think they are only interested in vaccines given right before a toddler regresses, at say age 12 months to 36 months.

Also, it seems that the PSC believes Eric Fombonne’s research is reliable when they want to make a point with it. They used his research to support the numbers of autistics who regress if I recall.

The transcripts will be available eventually (maybe soon), but we don’t know when. I think it would be interesting to compare get them to explain how many of this tiny group of ASD kids also have mitochondrial diseases or disorders. I wonder if they are trying to imply that the rest of the “epidemic” is caused by tuna mercury, chicken mercury or MMR, aluminum, assortative mating or what?

Autism Omnibus and shrinking hypotheses

13 May

The number of people who have made confident assertions about thiomersal causing autism over the last four years or so is astounding.

It’s now 2005…..[W]e should see fewer cases entering the system this year than we did last year.

– David Kirby

if the total number of 3-5 year olds in the California DDS system has not declined by 2007, that would deal a severe blow to the autism-thimerosal hypothesis…..total cases among 3-5 year olds, not changes in the rate of increase is the right measure.

– David Kirby

“Late 2006 should be the first time that rates go down” said Handley. “If they don’t, our. hypothesis will need to be reexamined.”

– JB Handley

…I would like to make a virtual wager that within the next 18-24 months scientific evidence will make the thimerosal-autism link a near certainty.

– Richard Deth, March 22, 2006.

All these statements have one thing in common, they promote the idea that mercury (thiomersal in particular) causes autism in either all, or the vast majority of cases.

However, listening to the Autism Omnibus yesterday provided a very interesting change from this perspective:

In some kids, there’s enough of it that it sets off this chronic neuroinflammatory pattern that can lead to regressive autism,” said attorney Mike Williams.

ABC.

Note the new language: ‘some kids’….’regressive autism’…..’can lead’.

It seems the days of ‘all autism is mercury poisoning’ are long gone.

Petitioners presented a very interesting expert witness yesterday – a Dr Sander Greenland from UCLA who is a Professor of Epidemiology.

Dr Greenland argued some strange facts for the PSC but completely in line with this new tack that I can’t even remember being argued in the Cedillo hearing (thiomersal may cause regressive autism in some kids).

Greenland essentially argued that all the current epidemiology regarding autism and thiomersal was not good enough to detect thiomersal causation in regressive autism – this is from his submitted report:

A simple example may clarify this point. If a vaccine is not associated with any type of disorder in the category, we should expect to see the same risk when comparing vaccinated to the unvaccinated. Suppose, however, that in reality the vaccine is associated with a two-fold increase in the risk of a type of disorder in the category, but not associated with any other type. Suppose also that, without the vaccine, the associated type represents only one-tenth (10%) of the disease category, and that the total number of cases in the category would be 100. Then, without the vaccine, the number of cases with the associated type would be 100/10 = 10. With the vaccine, however, the number of cases with the associated type would double, to 20, an excess of 10 cases over the original 10 with the associated type. This excess produced by the vaccine would result in a total of 100+10 = 110 cases over the full category, which is only a 10% increase in the risk of any type in the category. Thus, the risk ratio for getting any type in the category would be only 110/100 = 1.1. Such a small risk ratio cannot be reliably distinguished from 1 by ordinary epidemiologic studies.

In other words, the amount of autism caused by vaccines is in fact too small to be detected by epidemiology. If, of course, it is associated with it at all – a point made later by Dr Greenland:

The brief overview given above supports the idea that the association of MCV (mercury containing vaccine) with autism is small or nonexistent.

But really his point is that if thiomersal does cause autism (and whilst he professes to have ‘no opinion’ on the matter it may be telling that he refers to the idea as a hypothesis throughout his report, not a theory) it causes it in very, very small numbers indeed.

Dr Greenland passed no opinion the validity of the hypothesis itself. Rather, he was there to study epidemiology. We have to respect his opinion even if we disagree with it.

The more telling aspect for me was this sudden conversion from ‘vaccines cause autism’ to this suddenly tiny percentage – so small to be undetectable by epidemiology up to this point. That’s quite a step back. What will become of the Omnibus cases that are not considered’ regressive’? Or the ones (like Michelle Cedillo) who were claimed to be regressive but were, upon viewing the video evidence, clearly not. Are the PSC really throwing cases away?

Age of Autism Excels Itself

4 May

It’s my opinion that the blog Age of Autism has not ever once published a post that has contributed anything to the sum of human knowledge in a general sense, nor has it ever published a post that is designed to actually help autistic people live their lives.

However, every once in awhile, it publishes a post that is so monumentally stupid that I literally think the worse of myself for wasting time reading it. And here I am actually blogging about one. Sigh.

Such a post appeared today. It is entitled ‘CDC triggers measles outbreak’. The author of this post, ex-UPI journo Dan Olmsted says:

I’m starting to think we should rename the CDC the Centers for Disease Contagion. You’ve all seen the news that there are suddenly more measles cases in the United States and the CDC is blaming it in part on the increasing reluctance of parents to vaccinate their kids.

But it’s the CDC’s fault, and no other. Getting the “measles shot” means getting the MMR, and the MMR is “the autism shot” in the minds of many, many parents.

So, let me get this straight. It is the CDC’s fault that measles is making a return across the US? I see.

Its not, for example, the fault of the non-vaccinating upper-middle class soccer-mommies and daddies, for example:

Of the 64 people infected by the measles virus, only 1 had documentation of prior vaccination. Among the other 63 case-patients were 14 infants who were too young to be vaccinated. Many of the cases among US children occurred in children whose parents claimed exemption from vaccination due to religious or personal beliefs, or in children too young to be vaccinated.

Hell, no. _That_ couldn’t be the issue, right? Its obviously the CDC’s fault. Damn them for providing the vaccines and a schedule that has led to serious measles epidemics being held at bay in the US and the UK prior to the last 10 years of utter complacency and idiocy.

And why is Dan Olmsted happy to blame the CDC?

Let me tell you one reason why I’m not shy or circumspect about squarely blaming the CDC for this — because Jon Poling, Hannah’s dad, predicted something like this, or much worse, just a few week ago

And as we all know:

Dr, Poling is the real deal, educated at Johns Hopkins, devoted both to his daughter and his patients, tempered by reality. He’s mild-mannered. He’s mainstream. He’s credible.

Riiiiight. This is the same Jon Poling who was recently described by his co-authors as ‘muddying the waters’. The same Jon Poling who’s wife has been a subscriber to the vaccine hypothesis since at least 2001. The same Jon Poling who knowingly uses incorrect epidemiology.

I’m afraid that Jon Poling is right now in the process of extricating himself from the mainstream. And also from any concept of credibility. His refusal to approve access to information that would provide more accuracy to public statements members of his clique have made about the situation is testament to a man who is not governed by any reality other than a desire to push a pre-conceived agenda.

But really, the attempt to point the finger elsewhere by Dan Olmsted is nothing more than a childish ‘It wasn’t me! Its not my fault!’ when both logic and morality show quite clearly that if people decide to eschew something that might not only save their kids lives but the lives and/or well-being of the society in which they live then the finger of responsibility can only point in one direction.

Poling vs HHS – Something is definitely beginning to smell

30 Apr

Back in March I wrote a post highlighting my suspicion that we weren’t getting the whole story regarding the Poling’s. They had – at that time – failed to give permission to Dr Andrew Zimmerman to discuss the case, despite the fact that he was deply involved in the treatment abd diagnosis of Hannah Poling. He has still – to the best of my knowledge – not been given permission by the Poling’s to speak.

I also blogged Jon Poling’s own words on the subject of document release:

The HHS expert documents that led to this concession and accompanying court documents remain sealed, though our family has already permitted release of Hannah’s records to those representing the almost 5, 000 other autistic children awaiting their day in vaccine court.

and pointed out the strange incompatability with what the _court_ said:

in the case that is the subject of the media reports, if the parties who supplied documents and information in the case provide their written consent, we may then be able to appropriately disclose documents in the case.

where it is made crystal clear that the Poling’s had not in fact provided written consent to release their documents.

Further documentation from the courts has now been released which touches on this issue in more detail.

I want to thank M who can choose to name themselves further if they feel like it for helping explain these and for highlighting them in the first place.

The basic gist of this document is that *the Poling’s do not want all the information to be released* despite their oft-repeated claim to the contrary. What information do they not want released – and why?

Respondent points out in the filed Sur-Reply to Petitioners’ Motion for Complete Transparency of Proceedings (R’s Sur-Reply) that while petitioners “did undertake initial steps
necessary to permit discussion of their case before the Special Masters presiding in the Omnibus
Autism Proceeding and before representatives of the Petitioners’ Steering Committee[,] *[i]n fact,
it is respondent who first approached and asked for petitioners’ consent to permit the Secretary of
Health and Human Services to disclose medical information regarding this case* in order for the
Secretary to address inaccurate statements that were being made publicly concerning respondent’s position in this case.”

Now _this_ is a bombshell. It was _not_ the Poling’s who first wanted to release documents, it was HHS. They asked for the Poling’s consent to permit HHS to disclose medical information in order to ‘address innaccurate statements that were being made publicly’.

Well, well.

And there’s more. HHS had also heard aboout the press conference the Poling’s intended to hold:

Having received no response from petitioners, respondent contacted petitioners’ counsel to inquire about the proposed consent form and to “inquire whether press reports were true that petitioners were planning press conference for the following day.” Petitioners’ counsel replied to respondent, and represented during a status conference in this case, that the reports of a planned press conference were not true…….and two days later they held a press conference and appeared in
nationally televised and print interviews discussing the case.

So they lied about the press conference too. Petitioners Counsel is, of course, one Clifford Shoemaker.

What is going on here? Granted there are pre-conditions HHS also wanted placed upon the release of information but why won’t the Poling’s let key medical details that would ‘address innaccurate statements that were being made publicly’ be released right now? Why do they claim that they are asking for complete disclosure when it is clear they are not? Why did their counsel blatantly lie about the press conference?

This is very much an example to me of the ‘muddying of the waters’ that John Shoffner talked about recently.
