The pathogenesis of congenital hypothyroidism due to thyroid dysgenesis is still unknown. A point mutation in the TSH receptor (TSHR) of the hypothyroid hyt/hyt mouse invoked the TSHR as a candidate gene for congenital hypothyroidism. Therefore, we screened for mutations in the TSHR gene in patients with congenital hypothyroidism and hypoplasia of the gland. In one girl detected in neonatal scr...

Abstract Background A case of thyroid hormone deficiency which presented at birth. Thyroid hormones are essential for brain development and normal cognitive function. Common symptoms congenital hypothyroidism (CH) include constipation, decreased activity, increased sleep feeding difficulty. signs dry skin, macroglossia umbilical hernia. If is left untreated after birth, it can lead to permanent...

OBJECTIVE We investigated the prevalence of congenital renal and urologic anomalies in children with congenital hypothyroidism to determine whether further renal and urologic investigations would be of benefit. STUDY DESIGN Prevalence of congenital hypothyroidism was obtained from the New York State Congenital Malformation Registry. The occurrence of urinary tract anomalies were calculated fo...

Background: Although numerous observational studies have investigated the association between gender and risk of congenital hypothyroidism, the role of gender as a risk factor for congenital hypothyroidism remains unknown.Thismeta-analysis was conducted to summarize the epidemiologic evidence of the effect of gender on the congenital hypothyroidism occurrence, and also to identify the sex ratio...

In babies with congenital hypothyroidism, goiter and respiratory distress (due to upper airway compression/hypothyroidism) are rarely encountered as the first presenting signs. Computerized Tomography of neck revealed enlargement all thyroid gland lobes further laboratory hypothyroidism. Thyroid hormone replacement therapy was initiated early, which resulted in a significant reduction regressio...

Genetic defects resulting in deficiency of thyroid hormone synthesis can be found in about 10% of the patients with permanent congenital hypothyroidism, but the identification of genetic abnormalities in association with the transient form of the disease is extremely rare. We report the case of a boy with transient neonatal hypothyroidism that was undiagnosed in the neonatal screening, associat...

background the national program of neonatal screening was performed in 2005 in iran. according to the studies, the outbreak of congenital hypothyroidism (ch) was one in every 670 live births in 2011. the prevalence of the disease in the world is 1 in 3000. the mean prevalence of this disease in iran is estimated to be 1 in 1,000, which indicates a high prevalence of the disease in iran. conclus...
