Previous Article Editorial Board. The aim of this study was to clarify the contribution of scintigraphy for the diagnosis, management and prognosis of the children with CH, on basis the experience from the Nuclear Medicine department of Armand-Trousseau Children Hospital.
Clinical description The clinical manifestations are often subtle or not present at birth, probably as a result of trans-placental passage of some maternal thyroid hormone and the fact that many infants have some thyroid production of their own.
A planar scintigraphic acquisition, including stomach and bladder, was done 1 h after intravenous injection of 1. Common clinical features include decreased activity and increased sleep, feeding difficulty and constipation, prolonged jaundice, myxedematous facies, large fontanels especially posteriormacroglossia, a distended abdomen with umbilical hernia, and hypotonia.
In Western countries, congenitalle hypothyroidism is more likely to be associated with exposure to excess iodine, or with maternal thyroid blocking antibodies. It may be permanent or transient. A significant association was observed between TSH levels and etiology of HC, and between TSH levels and the percentage of iodine congenutale decrease after the perchlorate discharge test: The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment.
Thyroid scintigraphy in association with ultrasound permits a precise characterization of the etiology of CH. Etiological diagnosis is not necessary when initiating thyroid hormone treatment. Slow linear growth and developmental delay are usually apparent by months of age.
Frequent laboratory monitoring in infancy is essential to ensure optimal neurocognitive outcome.
Peripheral CH results from defects in thyroid hormone transport, metabolism, or action as in Allan-Herndon-Dudley syndrome or as a result of peripheral resistance to thyroid hormones see these terms.
We retrospectively reviewed all the children 0—3 months referred between January and December to the pediatric hospitals in Paris for the management of neonatal hypothyroidism.

Diagnostic methods In countries with newborn screening programs with either a primary thyroxine T4 -follow-up TSH or primary TSH testinfants are diagnosed after detection by screening tests finding an elevated serum TSH level and low T4 or free T4 level.
Other diagnostic tests thyroid radionuclide uptake and scan, thyroid sonography, or serum thyroglobulin determination may help pinpoint the underlying etiology and separate transient from permanent cases. The cause of thyroid dysgenesis remains unknown in the vast majority of cases. More specific symptoms often do not develop until several months of age.
