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

    It has been claimed that there is a positive association between the frequency of Down syndrome and the fluoridation of drinking water. It has also been suggested that this association is most pronounced in young women. Recent congenital malformations data obtained from birth certificates from large U.S. cities have been

    Background: A review of the safety and efficacy of drinking water fluoridation was commissioned by the UK Department of Health to investigate whether the evidence supported a beneficial effect of water fluoridation and whether there was any evidence of adverse effects. Down's syndrome was one of the adverse effects reported. The

    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
