Abstract

From the survey by Kilpatrick et al. (p. 654, col. 1, Vol. 32) it was possible to classify 696 schoolgirls in 4 groups according to intake of I, which was higher in those taking school lunches than in those not doing so because iodised salt was used for cooking, and according to intake of F, in some areas 0.7 and in others <02 p.p.m. in drinking water. Enlargement of thyroid had been assessed on 3 bases, visibly enlarged, not visibly enlarged, but with lobes palpably enlarged, or enlarged at isthmus but not necessarily at lobes. There was no indication that F was goitrogenic; its addition to water was not precluded. D. Harvey.

    Natural iodine deficiency and ambient air pollution with fluorine compounds were examined for their combined influence on the prevalence and severity of iodine-deficiency disorders. The excess intake of fluorine was shown to increase the incidence of thyroid diseases and to lower anthropometric indices in children. The preventive measures performed to

    A survey was conducted in eighteen fluoride endemic villages in Mehsana District of North Gujarat (India). The individuals afflicted with fluorosis were examined for apparent mottled teeth and skeletal complications. Samples of urine and blood of these individuals along with drinking water were collected and compared with samples obtained from

    Sodium fluoride was the first fluoride compound used in the fluoridation of drinking water and it is still commonly used for that purpose to prevent dental caries. It exerts toxic effects on many soft tissues and organs. The thyroid gland has a strong capacity for absorbing and accumulating fluoride. Objective: The

    OBJECTIVE: Apart from its well-known deleterious dental and skeletal effects, fluoride excess can have toxic effects on many other tissues. Fluoride, when in excess, is known to interfere with thyroid gland function. Fluoride-induced thyroid disturbances similar to those observed in iodine deficiency state in spite of adequate iodine intake have been

  • Is fluoride-induced hyperthyroidism a cause of psychosis among East African immigrants to Scandinavia?

    When people with a compensated fluoride-induced hypothyroidism move to a low-fluoride area, the fluoride-induced inhibition of the production of thyroid hormones ceases. In Scandinavia, the dietary intake of iodine is usually quite high due to iodized table salt and easy access to marine fish. Under these conditions, the elevated capacity for production of thyroid hormones may result in hyperthyroidism.

    Several lines of information indicate an effect of fluoride exposure on thyroid function. It is difficult to predict exactly what effects on thyroid function are likely at what concentration of fluoride exposure and under what circumstances.

  • Fluoride Exposure Aggravates the Impact of Iodine Deficiency

    A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and

    Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.
