congenital hypothyroidism

n.
Deficiency of thyroid hormone at birth, usually as a result of improper development of the thyroid gland, a genetic disorder affecting hormone production, or iodine deficiency during pregnancy. If untreated, the condition leads to stunted growth, intellectual disability, and other health problems.

congenital hypothyroidism

Congenital myxedema, cretinism Hypothyroidism of neonatal onset, which occurs in 1/±7000 births, more commonly in ♀, characterized by mental and physical retardation due to inappropriate thyroid development or inadequate maternal intake of iodine during gestation. See Myxedema.

hypothyroidism

deficiency of thyroid gland activity, with underproduction of thyroxine, or the condition resulting from it. Common in adult dogs, particularly certain breeds, as a result of an idiopathic atrophy of the thyroid or a lymphocytic thyroiditis. Alopecia, weight gain, mental dullness, fatigue, cold intolerance, infertility and neurological deficits are seen. In food animals the syndrome is classical neonatal colloid goiter. See also goiter.

autoimmune hypothyroidism
see lymphocytic thyroiditis.
congenital hypothyroidism
results from congenital thyroid dysgenesis, defective hormone synthesis or severe iodine deficiency. There is dwarfism, macroglossia and mental dullness.
iatrogenic hypothyroidism
may follow treatment for hyperparathyroidism in cats.
juvenile hypothyroidism
congenital hypothyroidism (above).
primary hypothyroidism
that resulting from disease of the thyroid glands.
secondary hypothyroidism
caused by a deficiency of thyroid-stimulating hormone, usually as a result of a lesion in the pituitary gland.
tertiary hypothyroidism
caused by a lack of synthesis or release of thyrotropin releasing hormone.

Iodine toxicity may result in a variety of conditions ranging from fetal and neonatal hypothyroidism and goitre, iodine-induced hyperthyroidism, thyroid underactivity, papillary thyroid cancer and an increased incidence of autoimmune thyroid disorders such as Hashimoto and Graves Disease (Dorea, 2002; International Council for the Control of Iodine Deficiency Disorders, 2001)
The use of iodine-containing medications such as potassium iodate throughout pregnancy however must be monitored as chronically high intakes of iodine may result in fetal and neonatal hypothyroidism and goitre (Dorea, 2002).

Fetuses whose mothers take excessive amounts of antithyroid drugs can be born with neonatal hypothyroidism and goiter.
Although there have been several reports of transient neonatal hypothyroidism in the literature (1115), we believe that this case is unusual because the mother had not received any previous medications or iodide treatment and had no known exposure to animals, and the interfering substance could not be identified as being a heterophile antibody.
