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

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

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

Goitre and Fluorosis in Kenya

Fluorosis and iodine deficiency disorders in India.

This review focuses on fluorosis and iodine deficiency disorders, two serious, highly prevalent metabolic disorders that are under-reported. These are caused by the two elements of the halogen family, fluorine and iodine. The former in excess and the latter in deficiency are the cause for concern. Excess fluoride (F–) consumption

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, 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.

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

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.
