Case studies.
Queniborough, Lympstone, Sardinia
On this page I will be providing
details and observations of ongoing case studies- updated as info.
comes in.
1.Queniborough, nr.Leicester, vCJD research.
The latest research into the vCJD cluster tells us nothing about
the cause or incubation period of the disease or why there is
such a high incidence of vCJD/CJD in Queniborough.
The proposal is that slight spillage of brain material, as a
result of splitting the skull, followed by a wipe only, clean of
the carcass, has raised the level of mutant bovine prion to a
very high level in the food chain in the area. It is suggested
that this traditional practice of splitting the skull was
employed by local butchers from whom victims families had
purchased beef. However this practice was fairly common in
throughout the UK at the time. No evidence is presented to show
the distribution of the practice.
There are many problems with this proposal.
In the eighties and much of the nineties, brain and spinal cord
material was used at high level in many processed meat products
consumed throughout the UK pies, soups, pasties, patties,
burgers, gravies, sauces and purees. The tiny additional fraction
of brain material entering the food chain from this spillage
would be totally insignificant in terms of total dose.
Therefore no additional risk in terms of meat products has been
established for Queniborough.
There is no experimental evidence that shows beef products in the
food chain can transmit BSE in animals. Work with homogenate is
not satisfactory because we dont eat homogenate .Science
must be precise.
There was a case of classical CJD 12 years ago in a road where 2
vCJD cases subsequently occurred This was ignored by the
team but is significant.
Theres recently been a case of Feline Spongiform
Encephalopathy (FSE) which was also ignored.
The pattern within this and other clusters such as Armthorpe and
Adswood is of cases very close together (200M ) which strongly
suggests it is environmental topography and not eating beef that
is the key to finding the cause.
Only when we know the cause and whether it is acute or chronic in
nature can we hope to estimate the incubation period.The claims
that this research gives us a good indication of the incubation
are incorrect because they can't point to a time ( a day, a month,
a year?) when the alleged infection occurred.
We have carried out preliminary research at Queniborough and
Armthorpe, Doncaster and have identified the following potential
risk factors:
Queniborough our main findings.
Many Local people reported chronic pollution incidents in the 80s
and 90s from a, now closed, dyeworks in Queniborough. Manganese
is used in dyes. A yellow dust would often settle around the
village.This could be breathed in, lodge in sinuses, get in the
eye. The eye(retina and lid) contains very high levels of prion
protein and TSEs are thought to start here.Oxidising agents may
be in the form of a di thiophosphate head lice shampoo.The risk
may only be when this gets in the eye. Exposure to similar
pesticides by spray drift could also be relevant here.
The nearby village of East Goscote was built after the war on the
site of an old munitions dump. Shortly after, the houses in
Ringway road were built where 1CJD and 2 vCJD cases have occurred,
300M across the fields in Queniborough.
Theres anecdotal evidence of 11 cases of ME/CFS on one side
of the high street.( The Ringway is off the high street) This is
interesting because ME does resemble moderate Mn toxicity.(I'm an
ME sufferer, my own intracellular Mn is near the top of ref.
range)
We took several soil, water and herbage samples around
Queniborough. Levels of Manganese are mostly high to v.high in
the area.This may reflect soil treatments as much as natural
levels- more research needed.
Sewage sludge spraying, with drift, has been carried out on some
of the fields. Reactive metals, such as Manganese, are usually
concentrated in these treatments.
Compare our findings in another CJD clusters : ie In Slovakia
there was a major problem with Mn pollution; very high natural
levels of Mn that underpinned the local subsistence diet; bio
concentration in some of their foods; brain tissue analysis
revealed Mn levels 10x normal in the CJD victims (unpublished
data from Dr David Brown, Cambridge Uni.)
This is only a start and well keep you posted as our
studies progress. CJD is a complex multi factorial disease like
Alzheimers.Some of the above points will probably turn out
to be red herrings- But you have to sift through all the likely
factors. We are not paid for this work and have to do it in our
spare time and we bear most of the expenses ourselves so progress
can be slow.

2.Lympstone, East Devon: vCJD
There have been 2 cases of vCJD in
Lympstone, a village on the Exe estuary. It's worth noting that
there have been a significant number of vCJD cases on the coast/hinterland.
One of our correspondents, who lives near by, drew my attention
to some Manganese sources in the area: old Mn mines just north of
Lympstone and a Geological survey of the Estuary cliff area at
Lympstone which can be read in full at - www.devon.gov.uk/geology/ESC.pdf
I quote from this study
'The origin of scattered soft black pebbles in the breccia seen
in the bay south of the bridge under the railway (at Lympstone)
is uncertain. They now occur as crumbling lumps in the cliffs,
and would have been hard rock when they were deposited. Since
then they have been broken down within the rock by chemical
reactions and the soft manganese rich powder that remains tells
us very little of what the original rock was.'
The Manganese is present as small hard rocks and deposits of a
putty like consistency. I couldn't find any examples of the soft
rich powder referred to above.These samples are mostly very low
down the cliffs and below the high tide mark. It's unlikely that
this is being spread by wind. Its probable that small amounts
will be dissolving in the river and the natural Mn levels are
much higher in the river basin. Changes are occuring due to
erosion that could potentially have increased the risk over
recent years.
There are many other relevant points in the survey such as the
presence of other potential free radical generating metals:
volcanic rocks - which are known to contain high levels of
reactive metals such as Mn (cf TSEs are often found in volcanic
environments : scrapie in Iceland, the Cheviots, Manna Island,
Sicily; Kuru in New Guinea etc )
'iron stained clay, coating the sand grains' - sand/excavations
are common at CJD sites
granitic strata.
Beef seems highly unlikely again. There's no
reason why BSE prion material, that was so common in the |UK,
should be dangerous in Lympstone (and a handful of other places).
One of the victims was a long serving Marine from the Lympstone
barracks. Due to the suspected long incubation period this long
service would be expected if, as I believe, the location is
biologically significant. It seems unlikely that he would have
bought and consumed beef from the local butcher. The local
butcher may however have supplied the barracks and this would be
easy to check.
There are a number of other factors of interest. There's a garden
centre/nursery in the village in which pesticides are often
sprayed. Our correspondent, who suffers from a chemically
generated CFS caused by a series of acute exposures, reported
severe symptoms from this spray drift when he lived in the
village. On moving he experienced considerable health
improvements.
This part of the estuary is known as 'tornado alley' and this
would be relevant to airborne pollutants.
The river exe has been the subject of several pollution incidents
over the years.
There's a sewage works near the Barracks.
I've taken samples from the area and am awaiting the results of
the analysis.
There's no obvious answer to this but the Mn and OPs are
suspicious -the route of exposure is problematic.The key lies in
the environmental/biological common ground shared by the two
victims dating back over a couple of decades.
