[Effects of fluoride on thyroid structure in chicks].
Objective: To investigate the effects of fluoride on thyroid structure in chicks. Methods: 250 one day chicks were randomly divided into 5 groups, 50 for each. Group I was the control, and other four groups, group II, III, IV, V were fed the diets containing 500, 1,000, 1,500, 2,000 mg/kg of

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

The investigation of effects of fluorosis on thyroid volume in school-age children
Aim To compare the urine iodine, luoride, and to measure thyroid volumes in 10-15-year-old children using ultrasonography, a gold standard in evaluating thyroid volume. Methods A total of 261 children were enrolled into the study group from the 4-8th grades of 3 different primary schools, which were in the zone with high fluoride

Endemic goitre in the absence of iodine deficiency in schoolchildren of the Northern Cape Province of South Africa
OBJECTIVE: The study was undertaken to investigate whether endemic goitre still exists in the Northern Cape Province of South Africa more than 55 years after it was reported and, if so, whether iodine deficiency, or fluoride in the drinking water, is linked to the goitres. DESIGN: Cross-sectional study of children in three pairs

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.

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.

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.

Mikhailets (1996): Functional state of thyroid under extended exposure to fluorides
Abnormalities in the thyroid function characterized by a decreased iodine absorption function of the thyroid, a low level T3 syndrome, and a slight increase of the TSH level are observed in cases of chronic fluorine intoxication in the industrial workers.
