NoMercury, the website of Dr Alan and Lujene Clark RN is a website dedicated to proving the idea that mercury causes autism. Alan Clark writes a loooooonngg open letter about it – an amassing of the evidence one assumes – in a page amusingly entitled ‘the science’.
Lots of people (including me) have debunked a lot of whats on that page and what the Clark’s believe and more will do so in the future no doubt. What I’ve been meaning to tackle for some time is their attempt to provide historical medical data to back up their claims that mercury causes autism.
In order to do this, they make use of a form of mercury poisoning called ‘Pinks disease’ which is a phenomenon rarely seen these days but which went through a few periods of high prominence, particularly in the early 20th century and again in the mid 50’s in the UK.
The Clarke’s make use of Pinks disease in order to try and explain why thiomersal only causes autism in such a very low set of kids:
Why does mercury toxicity at levels found in vaccines seem to only affect a subgroup of children, predominantly males? History provides the answer. The same target subgroup was noted in the early 20th Century during the epidemic of Pink’s Disease (Acrodynia) that was determined to be caused by mercury in teething powders given to children. About 1 in 500 children were afflicted, and some died as a result of this toxic insult.
Firstly, lets note that despite Clark’s claims above neither he nor Pinks disease reveal why autism affects mainly boys. There are no valid scientific theories that account for that fact. And lets be clear – in order for thiomersal to be taken seriously as a causative of autism, there damn well needs be. The absence of such data is (just like the evidence against the so called autism epidemic) another major unraveling of the conspiracy-theorists shroud of mystery.
Clarke then goes on to quote Dr. Thomas Clarkson, who, in his ‘The three modern faces of Mercury’ said:
It is interesting that not a single case of Acrodynia has been reported from exposure to vaccines despite the propensity of thimerosal to produce this syndrome when given in sufficient amounts.
Which is a great point. Clarke, of course, takes issue with it:
That remark is quite interesting in the face of many parental reports of just such a rash occurring in their child after a bolus of Thimerosal-laden vaccines in the 1990’s.
He then goes onto ‘prove’ his point by linking to a PDF on his own site that not only details a case study of Pinks disease but includes pictures so we can judge how Pinks disease makes kids hands and feet pink.
Intriguingly, I came across a differing version of these exact same images. There were two main differences between this report and the Clark’s – firstly, the report I found is hosted on a medical science database which tends to lend it a bit more credence. And the second difference? Well go see for yourself. Is it just me or has the level of ‘pinkness’ seemingly and magically drained away from the report on the Clarks website? Far be it from me to accuse anyone in the Clarke household of being a dab hand with Photoshop but if I was told I was going to look at something called Pinks disease I’d expect something more along the lines of whats on the Science site than whats on the Clarks site. You, Dear Reader, can make up your own mind.
Clarke then goes on to say:
Acrodynia is probably the most widely recognized form of mercury poisoning. Its symptoms have been documented as early as 1931 by Bancroft, Grant, Tanner, et al (Journal Lancet 71:56, 1931) and studied more extensively in the 1950’s by Warkany and Hubbard. In fact, a statement in some of their earlier work *is almost eerily predictive of the symptoms we are seeing today* since the iatrogenic exposure to mercury was increased significantly by the rapidly expanded immunization schedule beginning around the early 1990’s. Have their words from 1953 come back to haunt the medical community because mercury was left in vaccines?
Fascinating stuff. Except Clarke glosses over the pathology of Pinks disease. I mean, from what Clarke says about Pinks disease above you’d expect the pathology of Pinks and autism to be very similar.
The child becomes listless, no longer interested in play, restless and irritable. Generalised inconsistent rashes, which are protean, recur from time to time. Early, the tips of the fingers, toes, and nose acquire a pinkish colour and later the hands and feet become a dusky pink, with patchy areas of ischemia and cyanotic congestion. The colouring shades off at the wrists and ankles. These changes in the extremities are the most distinctive features of the syndrome and are responsible for the term pink disease. Frequently the cheeks and the tip of the nose acquire a scarlet colour.
As the disease becomes established, the sweat glands are enormously dilated and enlarged and perspiration is profuse. Secondary infection may lead to a severe pyoderma (a pus-like skin disease). There is desquamation of the soles and palms, which, though usually superficial, may be severe and recur during the course of the disease. The fingers and toes appear oedematous; the swelling is due to hyperplasia and hyperkeratosis of the skin. An outstanding symptom is constant pruritus with excruciating pain in the hands and feet. Children will rub their hands together for hours, and older children will complain of a severe burning sensation.
The nails become dark and frequently drop off. Occasionally, gangrene of the toes and fingers develop and trophic ulcers may result from the constant rubbing of the hands and feet. The hair tends to fall out and is often pulled out by the child.
There is photophobia without evidence of local inflammation of the eyes. The children shield their eyes or bury their faces in their pillows. The lax ligaments and hypotonia permit the children to assume unusual positions. In extreme cases the teeth may be lost; necrosis of the jaw bones frequently follows. Initially, the gums appear normal except for a slightly deeper red colour, later they become inflamed and swollen. Salivation then becomes pronounced, and the saliva often flows from the mouth in a constant stream. Anorexia is prominent, but because of the excessive perspiration large quantities of water are consumed. There may be diarrhoea and prolapse of the rectum is a frequent complication. The blood pressure and pulse rate may be increased significantly. Fever is usually not present unless there is some complication such as urinary tract infection or bronchopneumonia. Neurological symptoms are an important part of the syndrome and include neuritis, mental apathy, and irritability.
Early in the disease the tendon reflexes may be normal or increased, but later they disappear. There is not a true motor paralysis, but because of the soft, flabby musculature the child has no desire to walk and is hypotonic, listless and hypomotile. The severe pain prevents normal sleep. There is no time when a child with acrodynia appears happy or comfortable; the child does not play or smile, but appears dejected and melancholic, a picture of abject misery.
Does that sound anything – anything at all – like autism or autistic people you know? No, me neither. Clarke follows up with what one assumes is his knock out blow – ‘Autism – a Novel Form of mercury Poisoning’. A study that wasn’t good enough to make it into a proper science journal. One of the conclusions in that study and which Clarke points proudly to is:
Due to the extensive parallels between autism and HgP [mercury poisoning], the likelihood of a causal relationship is great.
Er, yeah. Extensive parallels. Right. It seems that the medical science of the time (and now) says that Pinks disease has a causal relationship with mercury. It also seems very obvious to me that Pinks disease shares no commonality with autism whatsoever. It also seems clear to me that Clark uses Pinks disease in a vague manner with nothing substantive to back up his assertion at all. We’re back to square one: Yes, mercury is bad – no there’s no evidence it causes autism.
