  • A survey of goiter morbidity in Ban Mae Toen, Northwest Thailand

    A number of cases of goiter have been reported from Ban Mae Toen (BMT) northwestern Thailand, therefore we carried out this study to evaluate the prevalence and severity of goiter in BMT. We suspected fluoride toxicity as a factor in this phenomenon, therefore we used a WHO model using photographs

  • Role of nitric oxide and vascular endothelial growth factor in fluoride-induced goitrogenesis in rats

    Endemic fluorosis is a serious problem in public health. Previous studies have indicated that patients with thyroid goiters usually live in fluoride-affected areas. However, the mechanism of goitrogenesis caused independently by fluoride is still unclear. The principle objective of this study was to investigate the possible roles of nitric oxide

  • Assessment of iodine status in children, adults, pregnant women and lactating women in iodine-replete areas of China

    BACKGROUND: Iodine deficiency disorders (IDD) are widespread in China. Presently, IDD have been put under control by Universal Salt Iodisation (USI) in China; however, there is a lack of evidence on whether the iodine status in adults, pregnant women and lactating women is optimal. This study was therefore conducted to assess

  • Epidemiological study of goitre in endemic fluorosis district of Gujarat

    Soft tissue fluoride toxicity is well established. Several animal and human studies of the effect of fluoride on the thyroid gland have shown conflicting results. Endemic fluorosis and goitre are widespread in India with considerable overlapping in different geographical zones. We examined 22,276 individuals for  presence of goitre and dental

  • Fluoride, Water Hardness, and Endemic Goitre

    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.

  • Fluoride & Goiter

    Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the

  • Fluorine in the Aetiology of Endemic Goitre

    The distribution of endemic goitre in the Punjab and in England is related to the geological distribution of fluorine and to the distribution of human dental fluorosis (mottled enamel). Inquiry showed the presence of dental fluorosis among school-children in two areas of Somerset where two previous observers had recorded a high incidence of goitre, and the absence of dental fluorosis in an adjoining area selected as control where endemic goitre was absent.

  • The Relationship Between Fluoride Exposure & Goitre in South Africa

    As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

  • Fluoride's Impact on Thyroid Hormones

    Up through the 1950s, doctors in Europe and South America prescribed fluoride for this purpose in patients with hyperthyroidism. (Merck Index 1968). Fluoride was selected as a thyroid suppressant based on findings dating back to the mid-19th century that fluoride is a goitrogen (a substance that can cause goiter). When used as
