Tamizaje neonatal de hipotiroidismo congénito, análisis de la evidencia actual y propuesta de tamizaje para la población mexicana

Although the benefit of early treatment of severe cases of congenital hypothyroidism to prevent mental retardation is clear, most of the new cases detected with the new strategies are mild, such as transient and persistent neonatal hyperthyrotropinaemia, for which the usefulness of treatment in neurocognitive development has not been proven in randomized clinical trials. The objective of this article is to make a screening proposal in the Mexican population based on the current available evidence and to establish future research areas that help to resolve these controversies.
