Microcephaly truth or fiction? The Zika Virus

Larvicide Manufactured By Sumitomo, Not Zika Virus, True Cause Of Brazil's Microcephaly Outbreak: Doctors (Tech Times)

Quote:

The microcephaly outbreak in Brazil, which coincided with the spread of the Zika virus, continues to stun the world, even months after the incident was first reported.

Pregnant women all over the world have been advised to take caution. The Zika virus infection has been linked to newborn babies with the birth defect microcephaly. This is a congenital condition in which babies are born with unusually tiny heads.

The notion, however, has recently been challenged by a group of Argentine physicians. The group suspects that the Zika virus is not to blame for the rise in microcephaly cases, but that a toxic larvicide introduced into Brazil's water supplies may be the real culprit.

Not A Coincidence?

According to the Physicians in Crop-Sprayed Towns (PCST), a chemical larvicide that produces malformations in mosquitoes was injected into Brazil's water supplies in 2014 in order to stop the development of mosquito larvae in drinking water tanks.

The chemical, which is known as Pyriproxyfen, was used in a massive government-run program tasked to control the mosquito population in the country. Pyriproxyfen is a larvicide manufactured by Sumitomo Chemical, a company associated [PDF] with Monsanto. However, PCST has referred to Sumitomo as a subsidiary of Monsanto.

"Malformations detected in thousands of children from pregnant women living in areas where the Brazilian state added pyriproxyfen to drinking water is not a coincidence," the PCST wrote [pdf] in the report.

Looks like Wikipedia is on the case

"jumping genes" from transgenic mosquitos

http://www.theecologist.org/News/news_analysis/2987024/pandoras_box_how_...

Here's a great theoretical hypothesis on how the 'jumping genes' could have lead to Zika causing microcephaly. While many focus on the larvacide, knowing that millions of mosquitos that were supposed to die based on the proposed mechanism may have survived due to environmental exposure to tetracyclines would allow these 'jumping genes' hundreds of millions of opportunities to transfer into other places in the genome. 

Interesting stuff, indeed.

One simple question

Of the 30 or so countries with Zika, how many have had microcephaly outbreaks? 

Of the 2,401 microcephaly cases 134 were confirmed as being related to Zika virus infection according to the applied case definition.

That's about 18%.

But I don't want to get bashed about vaccine denial, etc, etc.

Neurobehavioural effects of developmental toxicity (The Lancet Neurology)

Quote:

"A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations. Confounding from other substances seemed unlikely in most of these studies. Further characterization of the dose–response association would be desirable."

How foolish can we be?

OK, so we've been doing a developmental neurotoxicity experiment on the entire population.  All of our children are likely impaired at least slightly even if they show no signs of neurobehavioral problems.

And the experimental design goes something like this: 

"We got all of these cool chemicals that help industry/our economy to varying degrees.  Let's use them in such a way that everyone is exposed to them through air, water, soil, consumer goods, building materials, and food.  They probably aren't a problem, but if any of them are, there is no need to make any effort to gather data, we'll just, uh, sort of notice.  Since there will be alarmist who think they notice a problem when there isn't one, we'll set the highest standards for proof of harm and those of us who profit from the sale of the chemicals will dedicate some of our profits to lobby to reduce research funding, influence the outcomes of the research, and prevent legislative and regulatory action that limits our profits."

An awesome plan if I ever saw one.

Fluoride vs Tooth Decay
Quote:

 "... an average IQ decrement of about seven points in children exposed to raised fluoride concentrations. Further characterization of the dose–response association would be desirable."

Some important info is missing here: Raised by how much? Compared to what? This snippet sounds alarming but until we know the actual levels the children were exposed to we don't know what to think of it, or what it might have to say about water fluoridation in our own communities.

I noticed that paragraph because fluoride has recently been in the news here in Canada:


Quote:

A newly published study compared Grade two students in both Edmonton and Calgary, and found that fluoride cessation in Calgary has had a negative impact on children’s health.

Here's some history about how dentists figured out that fluoride was beneficial for teeth, and how that led to fluoridation of public water supplies:  http://www.cdc.gov/mmwr/preview/mmwrhtml/mm4841a1.htm

Quote:

 The hypothesis that dental caries could be prevented by adjusting the fluoride level of community water supplies from negligible levels to 1.0-1.2 ppm was tested in a prospective field study conducted in four pairs of cities (intervention and control) starting in 1945: Grand Rapids and Muskegon, Michigan; Newburgh and Kingston, New York; Evanston and Oak Park, Illinois; and Brantford and Sarnia, Ontario, Canada. After conducting sequential cross-sectional surveys in these communities over 13-15 years, caries was reduced 50%-70% among children in the communities with fluoridated water (emphasis added).

Fluoride Added to Drinking Water Dangerous

The Fluoride Danger was first explained to me by my PhD/MD friend back in 2008 who left medicine in disgust.   Over decades the displacement of calcium from bone and teeth by fluoride will result in bone breaks and cracked teeth.   And if fluoride is so good for teeth why don't Germans have an epidemic of teeth problems given they don't add fluoride to drinking water.  BTW if you have white spots on your teeth that is fluoride toxicity, something that happened to me as a kid playing sports 24x7 and drinking a lot of fluoridated municipal water when the add was insanely high.

Fluoride spots
Quote:

Maybe yes, maybe no. Excess fluoride can indeed cause spots on teeth, but it isn't the only possible cause.

In fact, it was dentists a century ago trying to figure out why mottled teeth were common in some regions who turned up evidence that up to a point, fluoride in the water correlated with better dental health (fewer cavities).

As with so many things in life, the keyword there is Up To A Point.

For a long time I didn't nor did my dentist know what caused the spots.   3 years ago I started to buy high quality spring water and switched to non-fluoride toothpaste.   The spots are now much lighter.

Good to know

That's good to know that the spots are becoming lighter.

I got curious about fluoride in my own region, and found a paper from my provincial government which you might find interesting. Among other things, it confirms what you said about how too much fluoride can be bad for bones.

Quote:

In adults, high levels of fluorides consumed for a very long period of time may lead to skeletal fluorosis. Skeletal fluorosis is a progressive disease, in which bones increase in density and become more brittle. 

Source:  https://www.gov.mb.ca/waterstewardship/odw/public-info/fact_sheets/pdf/factsheet_fluoride.pdf

That document says that water from the bedrock aquifer in my own area tests high for fluoride, with concentrations that exceed the drinking water quality standard (1.5 mg/L). Many farms around here have their own wells ... so file that under Yikes!

The concentration our municipal water systems aim for is less than half that.

The Island of Unintended Consequences

Sayer of the Law: It is a hard way, the way of being a man. Sooner or later we all want a thing that is bad. To walk on all fours. To suck up drink from a stream. To jabber, instead of saying the words. To go snuffling at the earth, and to claw on the bark of trees. To eat flesh, or fish. To make love to more than one, every which way. These are all bad things. These are not the things that men do. But we are men, are we not? We are men because the Father has made us men!

...

Dr. Moreau: Have you forgotten the house of pain? 

Sayer of the Law: You! You made us in the house of pain! You made us... things! Not men! Not beasts! Part man... part beast! Things!

--The Island of Dr. Moreau (1996)

fluoride/osteoporosis

It would be interesting to compare osteoporosis rates by area and see if it coincides with water fluoridation rates.
