goi·ter

(goy'tĕr)
A chronic enlargement of the thyroid gland, not due to a neoplasm, occurring endemically in some localities, especially regions where glaciation occurred and depleted the soil of iodine, and sporadically elsewhere.
Synonym(s): struma, goitre.
[Fr. from L. guttur, throat]

goitre

Enlargement of the THYROID GLAND from any cause. This may be due to overactivity of the gland in THYROTOXICOSIS, to HASHIMOTO'S THYROIDITIS, to infective thyroiditis, to DYSHORMONOGENESIS, to cancer of the gland or to iodine deficiency.

goitre

an abnormal swelling of the neck due to enlargement of the thyroid gland. This may be because of a lack of iodine in the diet (simple goitre) or to overactivity of the gland (exophthalmic goitre).

goitre

chronic, non-neoplastic enlargement of thyroid; more common in women than men; due to autoimmune thyroid disease and inflammation, iodine deficiency, dyshormonogenesis, drugs (sulphonylurea agents, carbimazole)

goiter, goitre

enlargement of the thyroid gland, causing a swelling in the front part of the neck.

adenomatous goiter
multilobular goiters cause thyroid enlargement in cats.
colloid goiter
is characterized by the presence of a large soft thyroid gland with its glandular space distended with colloid. Most cases occur in neonatal lambs, calves and kids which show a high rate of stillbirths and weakness and a high mortality rate. Enlarged thyroid glands and alopecia are good indicants of the existence of a nutritional deficiency of iodine, the usual cause of goiter in animals.
dyshormonogenetic goiter
an impairment in thyroglobulin synthesis is thought to be the cause of inherited, congenital goiter recorded in sheep, cattle and goats. The thyroid gland is enlarged, there is a high neonatal mortality, a silky wool in sheep and a rough, sparse haircoat in goats. Called also inherited goiter.
goitrogen-induced goiter
there are a number of goitrogens in the environment of grazing animals. Their effect is almost entirely on the newborn. Common agents are low level intakes of cyanogenetic glycosides, e.g. in white clover, the glucosinolates in Brassica spp. plants, and mimosine in Leucaena leucocephala.
hyperplastic goiter
diffuse hyperplasia is the standard response to dietary iodine deficiency and to poisoning by plant goitrogens. It may also be caused by persistent exposure of the fetus to a high iodine intake of the dam. See also iodide goiter (below). Neonates are the usual subjects and the disease is manifested by clinical goiter, often sufficient to cause dystocia, and weak neonates with a high rate of stillbirths and deaths soon after birth.
inherited goiter
see dyshormonogenetic goiter (above).
iodide goiter
that occurring in reaction to iodides at high concentrations, due to inhibition of iodide organification.
nodular goiter
an endocrinologically inactive nodular enlargement of the thyroids in old dogs and horses. In old cats similar goiters sometimes develop functional adenomas.

The recent study was about the total prevalence of goitre and urinary iodine excretion in Kashmiri schoolchildren after 15 years of iodisation.
The most common complaint at presentation was goitre (46%).
Despite being iodine replete, goitre continues to be prevalent in mild to moderate degree of endemicity in most states of India (4-8).
The survey also found that the prevalence of goitre (a thyroid gland dysfunction) in the country had dropped to eight per cent in 2009 from 40 per cent in 1994.
Unlike the preoperative visual impression, the goitre was larger than expected and there was still a huge oedema of the neck region.
At these high intakes, uptake of iodine into the thyroid gland appears to be inhibited, resulting in reduced synthesis of thyroxine and elevated secretion of TSH, which stimulates the thyroid follicles to enlarge and multiply, producing a goitre.

An enlarged thyroid gland not caused by cancer is sometimes called a goitre.
The long-term results were cancers, especially high rates of cancer of the goitre, and goitre nodules, with the ongoing effect on stunted growth and reduced immunities of children born 20 and 30 years after that event.
