Objectives: Preterm infants often present CH characterized by delayed TSH elevation. We describe the clinical and biochemical features and the evolution of CH in preterm infants with delayed TSH elevation, detected by the second screening for CH.Material and Methods: All preterm infants born between 2007 and 2014 negative to the first screening (b-TSH<10 mcU/ml) at 2–5 days of life and positive to the second screening at 12–33 days (b-TSH&#...

Introduction: Although there are several studies on the incidence of congenital hypothyroidism (CH), there are few data showing incidence and evolution of CH detected by the second newborn screening (NBS).Objectives: To assess the incidence of CH in Lombardia region and the percentage of patients identified by the 2ndNBS. To describe the clinical features and evolution of CH patients detected by the 2nd</...

A strategy of a second screening at 2 weeks of age, or 2 weeks after the first screening was carried out, is also recommended in preterm, LBW and VLBW neonates, twins, neonates admitted in NICU, and babies with specimen collection within the first 24 hours of life [1–3].
