Silver-Russell syndrome (SRS) is a rare heterogeneous syndrome associated with severe prenatal and postnatal growth retardation.Context: There is little information on puberty onset and bone age trend in children with SRS.Study Design and partecipants: Retrospective observational study, including patients with a confirmed diagnosis of SRS divided in 2 molecular groups [ 11p15 loss of methylation, (...

Silver-Russell syndrome (SRS) is an epigenetic disorder characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The most common genetic abnormalities are 11p15 ICR1 loss of methylation, (11p15 LOM) and maternal uniparental disomy of chromosome 7 (mUPD7). There is little information on cognitive development in SRS patients and no neuroradiological studies are available so far. Global developmental delay and requirement for speech t...

Background: Autosomal dominant neurohypophyseal diabetes insipidus (adNDI) is characterized by arginine vasopressin (AVP) deficiency resulting from mutations in the AVP-NPII genePatients and Methods: We analyzed AVP-NPII gene in 13 kindreds with familial NDIAim: To describe the clinical and molecular features of Italian kindreds with adNDIResults</str...

Background: Central precocious puberty (CPP) is defined as the secondary sexual characteristics onset before 8 years of age in females and before 9 in males, due to premature activation of the hypothalamic-pituitary-gonadal axis. The underlying cause remains idiopathic in the great majority; based on the 2009 Consensus, 2% to 7% of girls who have onset of CPP between the ages of 6 and 8 years have unsuspected pathology and only 1% have a tumor such...

Introduction: Hirsutism is a condition defined as excessive male-pattern hair growth in females most commonly caused by hyperandrogenism. Polycystic ovary syndrome (PCOS), non-classic adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency and androgen-secreting tumors represent causes of androgen excess. Common features such as hirsutism, polycystic ovaries, oligomenorrhea or amenorrhea, and insulin resistance make it hard to distinguish between the first...

Objectives: To assess the long-term impact of prematurity on bone and body composition by using Dual-energy X-ray absorptiometry (DXA).Methods: DXA scans were performed in 100 preterm (PT) (n=42F, n=58M, mean weeks’gestation 31.5±2.6; range 26−36) and 51 born at term (BT) healthy infants (n=28F, n=23M). DXA measures of total body and lumbar spine mineral density (TB/L1-L4 BMD, g/cm2 and Z...

Background: ROHHADNET syndrome affects children with normal development until 2–4 years of age.Objective and hypotheses: Aim of this study was to evaluate a possible role of autoimmunity in this disorder. In spite of a suspicion for genetic etiology, disease-associated genetic variations have not been identified. A paraneoplastic/autoimmune etiology has been suggested mainly because of the association with neural crest tumors....

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age, and is characterised by chronic inflammation and in most cases by insulin resistance besides ovulatory dysfunction and hyperandrogenism. HMGB1 is a small protein with cytokine activity that can activate nuclear factor kappa light chain enhancer of activated B cells (Nf-kB), and signals through the Receptor for advanced glycation end products (RAGEs) and through the T...

There is little information on metabolic profiles and Body Composition in children with Silver-Russell syndrome (SRS).Methods: 31 SRS patients [16 subjects with 11p15 loss of methylation (11pLOM) and 15 subjects with maternal uniparental disomy of chromosome 7 (mUPD7); mean age 7.4±4.3 years] and non-SRS subjects [34 small for gestational age (SGA), 13.4±2.7 years, and 44 appropriate for gestational age (AGA), 6.9 ± 1.4 ye...

Achondroplasia is the most common skeletal dysplasia caused by a gain of function of the fibroblast growth factor receptor 3(FGFR3) that impairs endochondral ossification, exiting in short stature and altered bone microarchitecture. Although fractures and reduced bone mineralization are not comorbidities frequently reported, specific normative DXA data are lacking. Aim of the study was to assess bone density parameters in an Achondroplasia cohort. Fifty-seven patients (Female-...
