Background: Rickets is a disease due to a reduced mineralization of the rapidly growing bones (skull, ribs, wrists, knees, ankles) with consequent accumulation of non-mineralized bone matrix, called osteoid tissue. The most frequent cause of rickets is vitamin D and/or calcium deficiency caused by reduced sun exposure, inadequate dietary intake or malabsorption (nutritional rickets).Clinical history: R., a 1 year and 6 m...

Background: Pediatric osteoporosis is a condition which can stem from genetic causes (Primary osteoporosis), from systemic diseases or from the chronic use of drugs that alter bone metabolism (secondary osteoporosis). Obesity affects bone health in several ways, including bone remodeling, proinflammatory cytokine production and bone marrow microenvironment alteration. We describe the case of a boy who presented spontaneous vertebral fractures.<p class="abs...

Introduction: I. was born at term by emergency caesarean delivery due to foetal distress, by unrelated parents. Birth weight: 2160 g (-3.18 SD), length 41.5 cm (-4.47 SD), head circumference 35.4 cm (0.57 SD). He was admitted in the neonatal intensive care unit (NICU) for the severe growth retardation associated to dysmorphic features. Neonatal screening, echocardiography and brain ultrasound normal. Karyotype: 46,XY.Case present...

Introduction: NR5A1 (nuclear receptor subfamily 5 group A member 1) is a transcriptional regulator of adrenal and gonadal development and function. Heterozygous and homozygous NR5A1 mutations have been described in 46,XY disorders of sex development (DSD). The clinical, endocrine and genetic features of three 46,XY children from two unrelated families (A and B) with NR5A1 genetic variants are reported.P...

Background and aim: Subjects with Turner Syndrome (TS) show low cortical bone mineral density (BMD), osteoporosis and risk of fractures. Previously, we demonstrated the enhanced spontaneous osteoclastogenesis in girls and young women with TS before and after pubertal induction with hormonal replacement therapy (HRT). The bone resorption observed in girls before puberty induction seems to be supported by the high FSH serum levels observed at prepubertal stage, while in young wo...

Hypercalcemia and nephrocalcinosis (NC) are rare findings associated with congenital adrenal hyperplasia (CAH), whose pathogenetic mechanisms are still unclear. In this study we aimed to investigate the prevalence of NC in a cohort of Italian children affected with classical form of CAH, and to correlate its association with metabolic control of the disease.Subjects and Methods: This is a multicenter one year-perspective study involving ...

Background: Subjects with non classical congenital adrenal hyperplasia (NCCAH) often present an increased growth velocity secondary to elevation of adrenal androgens that promote early bone maturation and compromise final height (FH). The aim of the study was to analyze prognostic factors affecting growth trajectory and FH in children with NCCAH.Design: retrospective, multicentric studyStud...

Background: Ovarian sex differentiation network involves a panoply of interacting factors. Yet, no single sex-determining factor has been identified to be an equivalent of SRY or SOX9 in the testis. Recently, data suggested CBX2 as a pioneer regulator promoting testis development. In addition to its implication in ovary pathway differentiation which remains unclear.Objective and hypotheses: To deepen our understanding of the regulatory network that under...

Purpose: The main purpose of the study is to assess the association between obstructive sleep apnea (OSA) and insulin secretion in children with obesity.Objectives: To achieve our aim we have assessed OSA and measured insulin secretion by the using the oral minimal model (OMM) in a cohort of 77 obese children and adolescents.Methods: We retrospectively enrolled children and adolesc...

Background: At present, literature regarding postnatal growth in small for gestational age (SGA) subjects and its’ correlation with growth factor levels is still controversial. A relation between IGF1 and IGFBP3 levels at birth and weight and length catch up growth has been demonstrated. In the first months of life a rapid weight catch-up growth has also been associated to an increase of leptin, basal insulin and insulin resistance.Objective and hyp...
