Background: Disorders of sex development (DSD) characterize incomplete or disorganized genital or gonadal development. One in 4500 births requires genetic and endocrine studies due to abnormal external genitalia or gonadal dysgenesis and only 50% of the cases receive a definitive diagnosis. There are several genes that participate in both sex determination and differentiation processes. Mutations in NR5A1 gene, which encoding SF1, a transcription factor, are responsib...

Background: Liver steatosis (LS) is diagnosed in obesity at very early ages, not exclusively related to overweight severity.Objective and hypotheses: To investigate the features of patients diagnosed with obesity associated LS (ultrasonography).Method: We retrospectively studied 88 obese (BMI>+2 SDS) children with LS (LS-OB) and 88 age, gender, race and puberty matched obese children without LS (no-LS-OB). BMI-SDS, body composi...

Introduction: Growth without growth hormone (GWGH) is a rare phenomenon described in patients with hypothalamic structural pathology who present a normal growth rate in spite of growth hormone (GH) deficiency and low concentrations of insulin-like growth factor-1 (IGF-1). Possible aetiologies involve hyperinsulinaemia, hyperprolactinaemia or hyperleptinaemia; however, the exact mechanism is still unknown.Objective: We ai...

Background: Liver steatosis (LS) results from ectopic fat deposition and can be present in obesity even at early ages. Similar to insulin resistance, the onset of LS does not seem to depend exclusively upon the severity of obesity and shows a large interindividual variability.Objective: Our objective was to develop a predictive normogram for LS in children and adolescents with obesity ba...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

In Italy, treatment of children with CP is not centralized. We collected data of 117 patients (pts) (M/F 56/41) with CP diagnosed after 01/01/2000, followed-up in 14 centres of paediatric endocrinology belonging to the I.S.P.E.D. Five centres provided data on more than 10 pts (range 12-19), while the remaining on 1-9. 46 pts were diagnosed between 2000-2010 and 71 afterwards. Follow-up was 7.5±4.1 yrs.Results. Histology was adamanti...

Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...

Background: Adherence to follow-up visits in children and adolescents with obesity is a key factor for successful therapeutic outcomes in these patients.Objective: To analyze the adherence to scheduled visits and drop-out rate and the anthropometric, metabolic and behavioral outcomes as a result of an intervention program in a large cohort of children and adolescents with obesity.Patients a...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; this increases the risk of coronary heart disease (CHD). Recent evidence suggests that sizes and composition of HDL may be more important that HDL-C levels in predicting CHD. There is not data regarding the HDL subclasses distribution and composition in T2D youths with hepatic steatosis (HE).<p c...
