Urinary stone formation involves fluoride…

Rathee, N., Garg, P., Pundir, C.S. Correlative study of fluoride content in urine, serum and urinary calculi. Indian J Clin Biochem. 2004 Jul;19(2):100-2. doi: 10.1007/BF02894265.

Abstract: Fluoride content was measured in 100 urinary stones retrieved by open surgery of stone formers admitted at PGIMS Rohtak and their respective urine and serum and compared with those of healthy individuals. The concentration of fluoride was also measured in the sources of drinking water of these stone formers. The concentration of fluoride was definitely significantly higher in serum (p>0.01) and highly significantly higher in urine (p>-0.001) of stone formers compared to those of healthy individuals. The content of oxalate in serum and 24 h urine of the stone formers was also measured, which was increased significantly (p<0.005 and p<0.001) compared to healthy individuals. The concentration of fluoride was probably significantly higher in drinking water of these stone formers than the normal ones. There was a positive correlation between the content of fluoride of urinary stones and urine of stone patients (r=.88); stone and serum (r=.62); drinking water and stone (r=.85) and their urine and serum (r=.54); urine and drinking water (r=.83) and serum and water (r=.51). These results indicate a definite role of fluoride in urinary stone formation.

Vancouver (Canada) company launches Happy Water…..with lithium.

Happy Water….Lithium is a mineral with chemical salt properties that have been used since the 1940′s in drugs for the treatment of severe depression and bipolar disorder. But is it beneficial, or even safe, in drinking water? Click here for news article…..

The global warming hockey stick is gone……forever.

Several writers have noted a new paper by the University of East Anglia reanalyzing temperature data making much needed corrections…..and ta daaaa….no more hockey stick.  Click here for the discussion at Watts Up With That. If I were Dr Mann, I would quietly admit that his prior hockey stick analysis and paper have been overtaken by events making it outdated and just move on with academic life. Life is too short to be stuck in the mud of an un-win-able lawsuit.

Melvin, T.M., Grudd, H., Briffa, K.R. Potential bias in ‘updating’ tree-ring chronologies using regional curve standardisation: Re-processing 1500 years of Torneträsk density and ring-width data.  Holocene, doi: 10.1177/0959683612460791

Abstract: We describe the analysis of existing and new maximum-latewood-density (MXD) and tree-ring width (TRW) data from the Torneträsk region of northern Sweden and the construction of 1500 year chronologies. Some previous work found that MXD and TRW chronologies from Torneträsk were inconsistent over the most recent 200 years, even though they both reflect predominantly summer temperature influences on tree growth. We show that this was partly a result of systematic bias in MXD data measurements and partly a result of inhomogeneous sample selection from living trees (modern sample bias). We use refinements of the simple Regional Curve Standardisation (RCS) method of chronology construction to identify and mitigate these biases. The new MXD and TRW chronologies now present a largely consistent picture of long-timescale changes in past summer temperature in this region over their full length, indicating similar levels of summer warmth in the medieval period (MWP, c. CE 900–1100) and the latter half of the 20th century. Future work involving the updating of MXD chronologies using differently sourced measurements may require similar analysis and appropriate adjustment to that described here to make the data suitable for the production of un-biased RCS chronologies. The use of ‘growth-rate’ based multiple RCS curves is recommended to identify and mitigate the problem of ‘modern sample bias’.

Fluorine Toxicosis – 1934

In the 1930s, several studies on fluoride were published such as the paper below. This paper reviews what was known about the harmful effects of fluoride. Keep in mind, harmful effects at that time were assumed to be mottling only, because mottling is so pronounced. Techniques for measuring and detecting more subtle biological effects caused by small amounts of substances were much more limited at that time.

Mottled enamel halted by changing to fluoride-free water supply…

In the 1930s, the work of H. Trendley Dean and Frederick S. McKay documented the observation that by switching to a low-fluoride water source, enamel mottling could be reduced in a community. A report examining high fluoride communites released in 1937 was published in the general literature in 1939:

H. Trendly Dean, Frederick McKay. Production of Mottled Enamel Halted by a Change in Common Water Supply. American Journal of Public Health, Vol 29, 590-596, June 1939.  Click here….

Three communities with endemic mottled enamel had changed their water supply to be nearly fluoride free and after 8-10 years saw a decrease in mottling.

Dean and McKay conclude that the production of mottled enamel was actually stopped by changing the water supply, thereby providing “the most conclusive and direct proof that fluoride in the domestic water is the primary cause of human mottled enamel.” In light of current science, this finding is to be expected. There is much scientific documentation that fluoride is a toxic substance. If drinking water contains a toxic substance, then it makes sense to remove the toxic substance from the water or change to a different water source that does not contain the toxic substance. There is no disagreement about this and studies in India and other countries confirm this observation.

More importantly, such studies focused only on dental fluorosis…..other measures of adverse health and welfare were not considered. In addition, Dean and McKay directly acknowledge that such fluoride studies are a “human experiment.”

“In specific water-borne diseases, the time intervening between the elimination of the antecedent cause and the nonappearance of the pathological entity is relatively short. The opposite characteristic of endemic dental fluorosis (mottled enamel) makes it unique among water-borne diseases. An interval in time between 8 to 10 years is required to carry out a human experiment that furnishes clinical proof that the development of the disease has stopped.”

Community intervention studies of populations are just that…..human experiments. Such epidemiology studies, however, do not provide “clinical proof”…..but only provide evidence.  Actual fluoride exposure was not measured and drinking water fluoride concentration was used only as a proxy.

Fluoride lobbyists sway Portland (OR) city council decision….

“The lobbyists did, in fact, meet with all five council members in July or  August, they have said, but only one of those initial meetings appears on public  calendars and only then under a vague heading, according to local Oregon  media.”

“If there was other contact, that could cast a pall over the entire  council because such meetings would appear to violate the city’s lobbying and  reporting requirements.”

Illinois Governor Quinn announces $1billion infrastructure slush fund….

Large amounts of money spent on infrastructure invariably turn out to serve as an infrastructure slush fund for labor and municipal employee unions…..pay back in effect. An annnouncement such as this (click here) at first sounds very noble, except that in this day of irresponsible state budgets money must be taken from something else in order be given to others.
