Background: MicroRNAs (miRNA) are small non coding RNA molecules, key regulators of metabolic pathways. Obesity is characterised by many metabolic changes. NAFLD is seen as a complication of obesity. FOXO-1, key regulator in insulin signalling, has been shown to be implicated in NAFLD. We previously identified miRNAs regulators of the FOXO-1 gene.Objective and hypotheses: To assess in serum whether the regulation of miR-146a and miR-486-5p, FOXO1 gene re...

Background: Low bone mineral density (BMD) is found in up to 50% of adolescents and adults with Prader-Willi syndrome (PWS). High fracture risk has been described in adult PWS patients. This bone fragility could be due to inadequate gonadal hormones levels during pubertal development, and to relative growth hormone insufficiency during childhood and adolescence. However, the mechanism/s of low BMD in PWS have not been clarified.Objective and hypotheses: ...

Background: The 5α-reductase-2 (5R2) deficiency is a rare 46, XY disorder of sex differentiation caused by mutations in the 5R2 gene. Diagnostic and clinical management is not well definite.Aims and objectives: To describe relevant features of 5R2 deficiency in a large sample.Methods: Retrospective records of persons with 5R2 deficiency were reviewed and clinical, endocrinological, genetic data analysed....

Background: The phenotypic spectrum of short stature homeobox-containing gene deficiency disorders (SHOX-D) ranges from non-specific short stature to Leri-Weill dyschondrosteosis. Current guidelines support rhGH in SHOX-D children, but long-term data are still lacking. Moreover, no correlation has been established yet between the severity of phenotype, including the response to rhGH, and the underlying SHOX pathogenic variant.Aims: To ev...

Introduction: It is known that excessive gestational weight gain can cause an adverse intrauterine environment and increase the risk of cardio-metabolic diseases in the offspring. Epigenetics could be one of the mechanisms involved in this regulation.Objective: We aimed to study the DNA methylation profile of umbilical cord tissue that is associated with gestational weight gain (GWG), and its relationship with cardio-met...

Background and Aims: Gestational obesity can cause metabolic programming in the offspring. Epigenetic modifications of DNA have been suggested as potential mechanisms underlying this programming. FRAT-1 is a gene involved in the WNT signaling pathway, which is an important regulator of adipose tissue development. The objective of this work was to study the methylation status of FRAT-1 in placentas of women with either normal weight or gestati...

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...

Mosaic variegated aneuploidy (MVA) syndrome represents a rare autosomal recessive disease characterized by aneuploidies with gain and loss of multiple chromosomes. We describe case of two Moroccan brothers with MVA2, due to CEP57 mutations. Patients are 17 and 13-year-old male siblings of a Moroccan healthy consanguineous couple. Oldest brother was delivered at 35 gestational weeks after IGR diagnosis, small for gestational age (SGA, 1300 grams, -3 SDS). Younger patient’...

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

Introduction: About 25% of children and adolescents with Type 1 Diabetes (T1D) have one or more associated autoimmune conditions. Although Graves' disease (GD) rarely occurs, considering the potential severity of manifestations, an early diagnosis and appropriate treatment are essential. The first line treatment is methimazole, whose use is not free from side effects; therefore, it is important to start with the most appropriate dosage.<p class="abste...
