Abstract (English): Congenital hypothyroidism (CH) is the most prevalent endocrine pathology, with an incidence that ranges between 1 in 1,200 to 2,500 live births, which has increased worldwide in recent years. Currently, neonatal screening establishes diagnostic suspicion from the first days of life, but when it is performed analyzing only TSH levels, it will not be useful to detect central hypothyroidism affecting hypothalamus and/or pituitary gland. Therefore, when CH screening is normal, but clinical signs of the disease are present during the first months of life, is important that the physician prompts an evaluation of thyroid function and/or the referral to a Pediatric Endocrinologist. Moreover, neonatal screening gives a suspicion of disease but is limited by false negative and false positive results that must be managed by the neonatal screening program together with the child´s Pediatrician. The basic principles to be monitored in those detected patients who require confirmation and treatment are outlined. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): El hipotiroidismo congénito (HC) es la patología endócrina más prevalente, con una incidencia estimada en 1 de cada 1,200 a 2,500 nacidos vivos, que ha aumentado en los últimos años en todo el mundo. En la actualidad, el Tamiz Neonatal permite establecer la sospecha diagnóstica desde los primeros días de vida; sin embargo, cuando se realiza analizando sólo los niveles de TSH, detecta casi todas las formas de hipotiroidismo primario por falla glandular, pero no es útil para detectar alteraciones originadas a nivel central (en el hipotálamo y/o la hipófisis). Por ello, cuando el tamiz neonatal con esta estrategia es normal y existen durante los primeros meses de la vida signos clínicos sugestivos de la enfermedad, es importante que el pediatra jerarquice la clínica, realice una valoración de la función tiroidea y derive oportunamente al especialista. El tamiz neonatal, que da un índice de sospecha de la enfermedad, tiene limitaciones: falsos negativos y falsos positivos, que deben tomarse en cuenta, tanto por los programas de tamizaje, como por los pediatras que reciben al niño en la consulta. En este artículo se señalan los principios básicos que deben vigilarse durante el proceso de confirmación y tratamiento en los recién nacidos detectados por el tamiz. [ABSTRACT FROM AUTHOR]
