  Endemic goiter is defined as thyroid enlargement in more than 10% of the population while sporadic goiter is a result of factors that do not affect the general population. Nontoxic goiter is more common in women than men. 3.1. [ocw.tufts.edu]

  These features were consistent with dyshormonogenetic goiter. [atm.amegroups.com]

  In our series, two elder siblings had Grade II goiter since birth, the third child did not manifest any goiter, which may be due to the fact that hormone replacement therapy was started quite early(4). [indianpediatrics.net]

  The presence in a thyroid gland of the combination of these morphologic features should suggest the diagnosis of dyshormonogenetic goiter. [link.springer.com]

  Graves dermopathy (pretibial myxedema) in children is virtually nonexistent. The thyroid hormone profile characteristically shows elevated T4 and T3 levels, accompanied by very low or undetectable levels of TSH. [hawaii.edu]

  Such pericardial effusions from myxedema typically resolve within a month of attaining euthyroidism. No restriction of activity is required for patients with hypothyroidism who are euthyroid on replacement therapy. [reference.medscape.com]

The initiation of treatment within first 2 weeks of life is crucial for the normal neurodevelopment. [31] Dosing Levothyroxine (L-T4) is the only recommended treatment for replacement therapy. [jcnonweb.com]

A T 4 less than 6.5 mcg/dL and a TSH greater than 20 mIU/L indicate abnormal values necessitating treatment with levothyroxine at a dose of 10 to 15 mcg/kg/day. 20 Treatment should be initiated as early as possible, since delayed treatment increases the [uspharmacist.com]

Management and treatment Levothyroxine is the treatment of choice (starting dose 10-15mcg/kg/day), with the immediate goal to raise the serum T4 above 130 nmol/L (10 ug/dL) as rapidly as possible; with these doses, serum TSH usually normalizes in 2-4 [orpha.net]

The etiology of CH was different from that reported in many other studies. The most common etiology of CH was dyshormonogenesis. [16] Female-to-male ratio was not similar to other studies in this field, which showed female predominance. [advbiores.net]

The etiology of TD, which is the most common cause of CH, is largely unknown. [dovepress.com]

Etiology Dyshormonogenesis is caused by hereditary defects in the steps of thyroid hormone synthesis and secretion, the majority of which are transmitted in an autosomal recessive manner but at least one condition has autosomal dominant inheritance. [orpha.net]
