Prevalence and manifestations of water-born fluorosis among schoolchildren in Kaiwara village of India: a preliminary study
Background: Fluorosis is an endemic condition with prevalence in 19 states and union territories in India. It is an urgent task to survey the fluorosis-related problems in these regions. Objective: To study the clinical manifestations of water-born fluorosis among schoolchildren in Kaiwara village of India. Methods: A cross-sectional study was conducted in

Thyroid function in endemic hydrofluorosis in Sicily.
In pursuit of former observations on hydrofluorosis the authors conducted an investigation concerning the incidence of goiter and the function of the thyroid gland in subjects with hydrofluorosis from Aquaviva Platani, a large endemic center of Sicily. To evaluate thyroid function, radio-iodine uptake and the conversion index (PBI) with 131I

[Action of the body fluorine of healthy persons and thyroidopathy patients on the function of hypophyseal-thyroid the system].
Altogether 123 persons were examined: 47 healthy persons, 43 patients with thyroid hyperfunction and 33 with thyroid hypofunction. It was established that prolonged consumption of drinking water with a raised fluorine content (122 +/- 5 mumol/l with the normal value of 52 +/- 5 mumol/l) by healthy persons caused tension

Correlation between drinking water fluoride and TSH hormone by ANNs and ANFIS.
Background: Artificial neural networks (ANNs) and adaptive neural-fuzzy Inference system (ANFIS) are the best solutions to finding the correlation between some water parameters and human hormones. The correlation between thyroid stimulating hormone (TSH) and drinking water fluoride studied by ANNS and ANFIS models in Yazd city. Method:

y-Aminobutyric acid ameliorates fluoride-induced hypothyroidism in male kunming mice
AIM: This study evaluated the protective effects of y-aminobutyric acid (GABA), a non-protein amino acid and anti-oxidant, against fluoride-induced hypothyroidism in mice. MAIN METHODS: light microscope sample preparation technique and TEM sample preparation technique were used to assay thyroid microstructure and ultrastructure; enzyme immunoassay method was used to assay hormone and

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.

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

Fluoride Aggravates Thyroid Damage Caused by Excess Iodine Intake
Chinese researchers have found that the combination of excess fluoride with excess iodine caused greater reductions in IQ, or greater increases in goitre than either scenario by itself.

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

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.
