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...

The new care paradigm for DSD promoted by the Chicago Consensus of 2005 raised many psychological challenges, the most important being the way decisions regarding the sex of rearing and diagnosis communication are made. The traditional care paradigm, sustained by a binary sex categorization, suggested that for newborns, the decision about the sex of rearing should be made as soon as possible and no later than 18 months of life and that little should be said to the involved per...

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...

Objective: To study the effect of orexin deficiency on metabolic and pubertal characteristics in narcoleptic children, we compared the metabolic and pubertal alterations between 15 children with narcolepsy with cataplexy (NC) and 15 control children matched for age, body mass index (BMI) z score.Method: Narcoleptic data were collected from the Reference Center for Narcolepsy and control common obese data from the department of pediatric endocrinology in ...

Background: Proteoglycans are abundant and structurally complex bio macromolecules. They reside on the cell surface and are a major component of the extracellular matrix including bone. Defective formation of proteoglycans may case pleiotropic connective tissue syndromes including EDS-like and Larsen syndrome–like phenotypes.Objective and hypotheses: We report on a girl with disproportionate short stature and joint laxity with pes planus and radial ...

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: Thyroid diseases are among the most common endocrine disorders affecting children and adolescents. These conditions are often associated with a wide range of skin disorders such as xerosis, mixedema, hypohidrosis, eczema, and more rarely hypertrichosis.Case: A 5-year-old female child was referred to our clinic due to short stature, Cushingoid appearance and marked hypertrichosis. At birth length and weight ...

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...

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...
