With this in mind, the follow-up schemes that were chosen in the studies that reported normal IQ outcomes can be used as recommendation. In a hypothyroid pregnant woman, the preferred approach is to treat the woman with rather than the fetus with LT4. Clinical experience suggests that the bioavailability of liquid LT4 preparations is higher than tablets, with a possible risk of overtreatment if tablet doses are used.

Acquired forms of CeH are usually sporadic and in most cases due to large pituitary macroadenomas with a suprasellar extensions, craniopharyngiomas and suprasellar tumors, head trauma, vascular accident or cranial irradiation 128 Treatment involves replacing the missing thyroid hormone to restore thyroid hormone levels to normal.

Several interventions have also diagnosis and management of congenital hypothyroidism proposed for improving the fetal outcomes of fetal hypothyroid disorders by considering the fetus as the patient to be treated and gaining direct access to the amniotic cavity. Furthermore, an early accurate diagnosis—in most cases achievable by dual imaging—abolishes the need for further diagnostic testing and re-evaluation of the cause later on.

Transplacental passage of a maternal thyrotropin receptor blocking antibody TRB-Ab causes a transient form of familial congenital hypothyroidism. Once diagnosis and management of congenital hypothyroidism therapy has been judged adequate, it should be reevaluated annually measuring serum FT4. Generally, blood tests are checked every 1 to 2 months up to 6 months of age and then every 2 to 3 months thereafter. In the real life, a good advise to render less likely a suspected interference is the use of alternative immunoassays including different antibody pairs or the measurement of TSH levels after removal of the interfering immunoglobulins by treating the serum with polyethylene glycol or protein G or by dilution and recovery test 1 Substances Thyroxine.

CH is one of the most common preventable causes of mental retardation. For new programs, there is a need to decide on the scope of screening to define the strategy for selecting neonatal screening tests. In contrast to adults, in neonates, infants and children LT4 can be administered together with food but with avoidance of soy protein and vegetable fiber ; more important, LT4 should be administered at the same time every day, also in relation to food intake.

Recommendations: The recommendations include: worldwide neonatal screening, approaches to assess the cause including genotyping and the severity of the disorder, the immediate initiation of appropriate L-T 4 supplementation and frequent monitoring to ensure dose adjustments to keep thyroid hormone levels in the target ranges, a trial of treatment in patients suspected of transient CH, regular assessments of developmental and neurosensory functions, consulting health professionals as appropriate, and education about CH.
