Background: Endogenous GH secretion physiologically increases during puberty. In particular, a correlation between GH levels and pubertal stages can be stated. Therefore, it is possible that some patients with childhood-onset GH deficiency (GHD) at puberty normalize their GH secretion. Finally, there are not so far assessed potential predictors of persistent GHD in patients during puberty.Objective and hypotheses: Our study aims evaluating the normalisat...

Pseudohypoparathyroidism (PHP) is an hereditary disorder characterized by resistance to parathyroid hormone (PTH) and in varying degrees to TSH, GHRH and FSH/LH, and caused by loss-of-function mutations in the GNAS gene, encoding the membrane protein Gs-alpha. Pathognomonic of these patients is a dysmorphic phenotype, called Albright's Osteodystrophy, which includes short stature, obesity, round face, mental delay, subcutaneous ossifications and brachydactyly. The most fr...

Background: Recent studies have analyzed the influence of perfluoroalkylated substances – PFAS (in particular PFOS and PFOA) on people and thyroid. Children are primaly affected by these pollutants. On the other side variation of incidence of congenital hypothyroidism (CH) has been shown in recent years by different studies. We sought to determine whether the incidence of CH in north-eastern Italy has changed in relation to some endocrine disruptors and t...

Objective: Neonatal hyperthyroidism is a severe but generally transient condition with a 2% prevalence in offspring of mothers affected by Graves' disease. It is caused by the transplacental passage of maternal anti-thyrotropin receptor stimulant antibodies (TRABs). Here we report the cases diagnosed at our centre between 2015-2019 in order to re-evaluate the diagnostic and therapeutic approach to this challenging neonatal thyroid alteration.<p cla...

The patient was referred to our Centre for short stature. Weight and length at birth were within normal limits. In the neonatal period he showed jaundice and hypoglycemia. A reduced growth velocity was reported from the age of six months. At 15 months his length was 70 cm (−3.75 SDS), his weight 8.1 kg (−2.26 SDS). Parental target height was 167.6 cm (−1.38 SDS). He had normal psychomotor development. The examination showed macrocrania and nasal voice. Blood ...

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&#...

Background: Autoimmune hepatitis (AIH) and methimazole (MMI)-induced toxic hepatitis are both rare diseases in pediatric age.Case presentation: We present the case of a 15-year-old girl affected by idiopathic arthritis and autoimmune thyroiditis. The autoimmune thyroiditis was diagnosed at 13 years of age. At 15 years old she developed hyperthyroidism (TSH <0.01 mcU/ml, FT4 2.3 ng/dl, FT3 8.4 pg/ml, TRAb 18 IU/l) and was treated with MMI (0.28 mg/kg ...

Background: Gliomas are the most common subgroup of CNS tumours in children. Histologic grading is a means of predicting the biological behavior of these tumours and survival is strongly correlated with tumour gradation. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, nuclear translocation of the type 1 IGF1R has been demonstrated in tumour tissues. Although the IGF1R expression has been described in C...

Background: Neonatal screening strategies revealed an increase in hypothyroidism associated with an in-situ thyroid gland due to TSH receptor (TSHR) mutations. While there are many genetic and functional studies regarding TSHR mutations, few are found concerning the clinical course and long-term outcome of TSH resistance involving the pediatric population.Objective and hypotheses: To determine the impact of TSHR mutations on clinical course, biochemical ...

Background: Distal chromosome 16 duplication syndrome, also known as 16q partial trisomy, is a very rare genetic disorder. Smaller chromosomal copy number variants (CNVs) within the 16q region create partial trisomies, which occur less frequently than full trisomy 16q. Trisomy 16q is generally associated with a multisystemic phenotype including intrauterine growth restriction (IUGR), brain and cardiac defects, intellectual disability and an increased risk of b...
