Abstract

A new statistical study on the distribution of mongolism in cities in Illinois, United States, from January 1, 1950 to December 31, 1956, permits us to verify an increasing frequency of this affliction associated with the concentration of fluorine in the drinking water.

This study follows a preceding inquiry on the prevalence of cases of mongolism born before 1950 in the same state.

Such inquiries should not be conducted in other countries without an evaluation of the contribution of fluorine from diet which varies from country to country.

The role of the advanced age of the mother, in the etiology of mongolism, would seem to reflect a slow and progressive accumulation of fluorine in the mother’s body.

    1) The low incidence of dental caries observed in mongoloid patients led to an investigation of the role of fluorine in this condition. 2) A statistical study of the geographical distribution of mongolism in Wisconsin, Illinois, Idaho, North and South Dakota (U.S.A.) shows a parallelism between the prevalence of this condition

  • Fluoridation and the occurrence of Down's syndrome

    The prevalence rates of Down's syndrome at birth were compared for Massachusetts residents ingesting fluoridated and non-fluoridated water. The observations included nearly all children born alive with Down's syndrome in Massachusetts during the 17-year period 1950-1966. A rate of 1.5 cases per 1000 births was found for fluoride-related births and

    Down syndrome (DS) birth rates (BR) as a function of maternal age exhibit a relatively flat linear regression line for younger mothers and a fairly steep one for older mothers with the second line intersecting the first line a little above maternal age 30. Consequently, overall DS-BR for all maternal

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts
