Non-autoimmune hypothyroidism is characterized by high serum TSH level, normal or low thyroid hormones, absence of autoantibodies and normal or hypoplasic in situ thyroid gland. It is known that heterozygous mutations in the TSH receptor gene (TSHR) are associated with partial TSH resistance which clinically ranges from isolated hyperthyrotropinemia to non-autoimmune hypothyroidism. Despite this, an absence of mutations in the TSHR gene has been repo...

The proband is a Caucasian girl with primary amenorrhea and no breast development at the age of 16 11/12 yrs. Unrelated parents; an older brother in good health and a twin brother (GA 31 days; BW 1450g) with reported agenesis of the corpus callosum and socio-emotional behavioral problems. The mother (menarche 14 yrs. and bicornuate uterus) presented four early spontaneous abortions and one stillborn fetus (46, XX) in the 6th month of pregnancy; remaining negative family histor...

Introduction: PROKR2 is a 384-amino acid G-protein-coupled receptors (GPCR) that regulates GnRH secretion in the hypothalamus. PROKR2 mutations have been described as cause of a certain percentage of of hypogonadotropic hypogonadism and Kallmann syndrome.In 2017 a heterozygous frameshift gain of function mutation of PROKR2 was identified in a 3.5-year-old girl with central precocious puberty (CPP).The aim of our st...

Background: In young adults patients (pts) with CAH due to 21OHD few and conflicting data have been reported on bone mineral quality (BMQ) evaluated by quantitative ultrasound (QUS).Objective and hypotheses: To evaluate the bone mineral status by QUS variables assessed at proximal phalanges of the hand in a cohort of young adults with classical CAH due to 21OHD and the possible associations with their clinical and metabolic features.<p class="abstext...

Background: Thyroid nodules (TN) are rare in children but often show more aggressive features than in adults. Irradiated childhood cancer survivors (CCS) are at risk for malignant thyroid nodules.Objective and hypotheses: To retrospectively compare the incidence of differentiated thyroid cancer (DTC), the clinical onset and the medium-term follow-up in a pediatric population (EC <18 years), with and without risk factors examined for TN, among 1990 an...

Background: A high risk of congenital hypothyroidism (CH) has been documented in multiple pregnancies. Over the years special screening procedures for preterm and twin babies (re-screening at 2–4 weeks of life) have been adopted by many screening laboratories worldwide. However, no extensive studies have been performed to verify how many co-twins with negative test at first screening (3–5 days of life) become positive at re-screening, and the utility of a long-term f...

Background: The isodicentric Y (idic Y) is one of the most common aberrations of the Y chromosome. Most patients (pts) are chromosomal mosaics, including 45,X cell line.Objective and hypotheses: Our aim is to describe clinical and molecular features of our 45,X/46,Xidic(Y) cases.Method: We retrospectively evaluate the clinical description of nine cases (six females, one male, two with ambiguous genitalia) with mosaic karyotype 45,X...

Background: Thyroid dysgenesis has been considered a sporadic disease, but recent observations suggested a possible genetic basis.Objective and hypotheses: The aim of our report is to evaluate the incidence of hormonal and ultrasound thyroid anomalies in siblings of CH patients with thyroid dysgenesis.Method: In Emilia-Romagna Region (Italy) 328 CH infants were diagnosed by neonatal screening between January 2000 and December 2012....

Background: Final height (FH) in patients (pts) with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is often under the genetic target, despite improvement of new therapeutic strategies.Objective and hypotheses: The aim of this study is to evaluate FH in a cohort of pts with CAH due to 21OHD diagnosed before and after newborn screening (NBS) era in Emilia-Romagna, Italy.Method: We evaluated final heigh...

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...
