Background: Pseudohypoparathypoidism (PHP) type 1A is a rare endocrine disorders caused by GNAS mutation. Patients phenotype with PHP type 1A include obesity, round facies, brachydactyly, subcutaneous ossifications, short stature. The resistance of action of parathyroid hormone (PTH) leads to hyperphosphatemia, hypocalcaemia and secondary hyperparathyroidism. Hypercalcitoninaemia has been described in limited patients with PHP without thyroid patholog...

Introduction: Central Precocious Puberty (CPP) has recently been described in patients with isolated or syndromic neurodevelopmental disorders, with greater attention from the scientific community. We carried out this study to compare the main aspects of non-isolated and isolated forms of CPP.Methods: We conducted a retrospective monocentric study, collecting all treated cases of CPP from 1st January 2013 to 31 December ...

Transient neonatal diabetes mellitus (TNDM) occurs in 50-60% of all cases of neonatal diabetes mellitus (NDM). The most common cause of TNDM (70%) is almost invariably associated with defect in chromosome 6 and mutations in the KCNJ11, ABCC8, INS, NHF1B etc. genes. TNDM is caused by mutations in the GATA6 gene in rare cases. This gene encodes a transcription factor that is important for the development of the hematopoietic, cardiac and gastrointestinal systems.<p class="ab...

Introduction: Severe insulin resistance due to insulin receptor mutation is usually diagnosed at the neonatal period (Donohue and Rabson-Medenhall syndromes), or later in a type A insulin resistance syndrome. We report here two cases of insulin receptor mutation whose presenting signs were less noticeable.Observation: A 13-year-old girl was referred for short stature (Height −2.5 SDS) with SGA (birth length 44.5 cm, at gestational age 41 weeks). Cl...

Introduction: Multinodular goiter (MNG) is a common disorder of the thyroid gland, characterized by thyroid enlargement due to the development of multiple hyperplastic nodules. It is infrequent in children. Here, we present the case of two families with novel DICER1 mutations and familial history of nodules in adolescence.Observations: A 10-year-old female presented a MNG. TSH, Free T3, Free T4 were in the normal range and thyroid autoantibodies were neg...

Background: In 2003 recombinant human growth hormone (rhGH) was approved by European Medicines Agency to treat short children born small for gestational age (SGA), but so far no study evaluated the prevalence of SGA children with short stature who qualify for rhGH treatment in Europe.Objectives: To investigate the prevalence of SGA and short stature in children born SGA and of SGA children who qualify for rhGH treatment ...

Background: Congenital isolated ACTH deficiency (IAD) is a rare inherited disorder that is clinically and genetically heterogeneous. Patients are characterized by low or absent cortisol production secondary to low plasma ACTH despite normal secretion of other pituitary hormones and the absence of structural pituitary defects. Mutations in the TBX19 gene, a T-box factor selectively expressed in developing corticotroph cells, have been identified so far only in cases of neonatal...

Introduction: The diagnosis of GHD requires the coexistence of anamnestic, auxological and laboratory data. The latter are burdened by the poor accuracy and adverse effects of the stimulation tests. A recent european audit (Horm Res Paediatr 2019;92(3): 150-156) on GH diagnostic reported as preferred tests in Italy Insulin tolerance test (ITT), glucagon, clonidine, arginine and Arg-GHRH. We conducted a survey to explore which of them are most used in It...

Background: CDC (Centers for Disease Control and Prevention) reported an increased risk of newly diagnosed diabetes over 30 days after SARS-CoV-2 infection among persons aged < 18 years. Similarly, the results from the DPV Registry demonstrated a significant increase in the incidence of pediatric Type 1 Diabetes during COVID-19 pandemic. The underlying mechanisms are not yet elucidated.Aim: To investigate the incidenc...

Introduction: Pathogenetic mutations in the HSD17B3, located on chromosome 9q22, lead to 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) isoenzyme deficiency, etiopathogenetic for a disorder of sex development (DSD) with 46 XY karyotype and female phenotype at birth. 17β-HSD3 isoenzyme, expressed at testicular tissue, catalyzes the synthesis of testosterone from Δ4-androstenedione, allowing the correct development of male external genit...
