Abstract
The results of analyses of the mineral content of drinking water from three Indian villages with endemic fluorosis surveyed for the incidence of thyroid enlargement are reported.
With the possible exception of temporary thyroid enlargement encountered in pubertal subjects (type b), no relation was found between the incidence of endemic goiter and the fluorine in the water supply.
Excerpt:
With regard to the slight and temporary enlargement of the thyroid encountered in the age group 14-17 (type b), detailed scrutiny of the data . . . reveals that with a fall in mean fluorine content of the water from 10.7 mg/l in Kamaguda to 5.4 mg/l in Yellareddyguda, there was a corresponding progressive fall in the incidence of pubertal goiters from 40% in Kamaguda to 9% in Yellareddyguda, However, associated with the fall in fluorine content there was also a rise in mean iodine of the water. The figures can be interpreted to indicate that, so far as type b goiters are concerned, (1) fluorine may be actually goitrogenic, and (2) high concentrations of iodine may have a goiter-preventing effect. Investigations in other areas, where the variations in fluorine content are not associated with variations in iodine content of the type encountered here, may throw light on this particular problem.

Fluorosis in some tribal villages of Dungarpur district of Rajasthan, India
The prevalences of dental and skeletal fluorosis were observed in fifteen tribal villages of the Dungapur district of Rajasthan where the fluoride (F) concentration in drinking waters varies from 0.3 to 10.8 ppm. At 1.40 and 6.04 ppm mean F concentrations, 25.64% and 84.43% of school children (<16 years), and

Goitre in school girls of the Mewat area of Haryana
A survey was carried out on 5449 school girls aged 10-16 years in the Mewat area of Haryana for goitre. The overall prevalence of goitre was nearly 29.5%. Thus goitre was a public health problem in the region. Analysis of the water sources in the study population used for drinking

Endemic goiter associated with high iodine intake in primary school children in the Saharawi Arab Democratic Republic.
The high prevalence of goiter in Saharan children visiting Asturias in the summer prompted us to study the problem in greater depth. Neck palpation was performed in a sample of 570 school children from the Saharawi Arab Democratic Republic. Weight, height, T4, thyroid-stimulating hormone and anti-thyroperoxidase antibodies in capillary blood were

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 & 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.

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.
