A was born at 38+4 weeks by eutocic delivery, with adequate auxological parameters and unremarkable perinatal history. She was admitted to our center at 15 days of life after the second screening for congenital hypothyroidism (CH) resulted positive (bTSH 48 mU/L); the first test was negative. Serum blood tests confirmed the diagnosis of CH (TSH 157 mU/L, FT4 0.96 ng/dl, FT3 8.44 pg/ml, negative thyroid autoimmunity). Thyroid ultrasound showed a gland of normal size. Therefore,...

We present the case of a five-day female admitted to our Paediatric Unit due to TSH elevation (bTSH 303 mIU/L) on routine neonatal screening for congenital hypothyroidism (CH). The patient was born at 38 weeks’ gestation by c-section presenting with adequate auxological parameters. Her mother suffered from Hashimoto’s disease, already diagnosed before pregnancy, and requiring Levo-thyroxine therapy (L-T4). Blood tests performed at five days of life revealed the pre...

Introduction: Familial non-autoimmune autosomal dominant hyperthyroidism (FNAH) is a rare cause of childhood hyperthyroidism caused by an activating variant of the thyroid stimulating hormone receptor (TSHR) gene. This disorder may occur as a result of an autosomal dominant inheritance or sporadically through de novo variation. The severity of hyperthyroid symptoms is variable and phenotype differences have been described in subjects harbouring the same mutati...

Background: Central hypothyroidism (CeH) is a rare thyroid hormone deficiency due to an insufficient stimulation of a normal thyroid gland. Candidate genes for isolated CeH include TSHβ, TRH receptor (TRHR) or IGSF1 genes while the combined pituitary hormone deficits (CPHDs) are the consequence of defects in embryonic pituitary transcription factors or in the prokineticin receptor 2 (PROKR2).Patients series: Here we report nine males (M) and 15 fema...
