Background and Aim: Multifaceted risk factors impair bone mass (BM) in childhood brain cancer survivors(CBCS). Aims of the study were to evaluate bone mass and it's determinant and fracture prevalence in CBCS 2(G+2), 5(G+5) or 7(G+7) years after off therapy (OT).Methods: Seventy-three(G+2), 87(G+5) and 66(G+7)CBCS were evaluated at 12,9±4,2, 14,9±4,4 and 16,6±4,4yrs, respectivel...

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...

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....

Background: ROHHAD (rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation) syndrome is a rare and underdiagnosed disease with high mortality rate. When a neural crest tumor (NET) is detected (56% of patients) the acronym used is ROHHADNET.Aim: To analyze the relationship between clinical variables, hypothalamic-pituitary disorders, DXA parameters and neural tumors, in ROHHADNET patie...

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...

Background: ROHHAD/ROHHADNET syndrome (rapid-onset obesity with hypothalamic dysfunction, central hypoventilation, autonomic dysregulation with or without neural tumor - NET) – has been reported in association with cerebral venous thrombosis events, as reported also in central hypoventilation syndrome. It is not clear whether thrombotic risk represents a cause or a consequence of hypoventilation and hypothalamic dysfunction. Aim of our study was to chara...

Background: ROHHAD syndrome (rapid-onset obesity with hypothalamic dysfunction, central hypoventilation, autonomic dysregulation) – also defined as ROHHADNET when associated with neural tumors - is a rare condition with a high mortality rate. The aim of this study is to describe the phenotypes of a multicentric cohort of ROHHAD patients.Patients and Methods: We retrospectively analyzed clinical data from 22 patient...
