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...

Introduction: Continuous Glucose Monitoring (CGM) devices have introduced new metrics to assess metabolic situation of patients with type 1 diabetes mellitus (T1DM). Among them, the glucose management indicator (GMI) provides a proxy to HbA1c, however, these measures do not always match.Purposes: To evaluate the concordance between GMI and HbA1c, and determinate in which scenarios GMI could replace HbA1c.Subjects a...

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...

Introduction: The influence of sex chromosomes and sex hormones on early human brain development is still poorly understood. Expression of Y chromosome genes may influence aspects of brain maturation in the 46,XY fetus, but the contribution of different Y genes is unknown. Furthermore, a marked increase in testicular testosterone biosynthesis/release from the testis occurs at around 8 weeks post conception (wpc) in the 46,XY fetus, but it is unclear whether te...

Introduction: Noonan syndrome (NS) is one of a group of diseases known as rasopathies, which share a common molecular substrate: alterations in the RAS-MAPK signaling pathway. NS is characterized by clinical and genetic heterogeneity. Up to 50% of cases are caused by variants in the PTPN11 gene, although more than 10 genes have been identified as involved in the pathogenesis of this disease with marked clinical overlap.Objectives...

Introduction: Diabetes insipidus (DI) is a rare disease in children. In most cases it is acquired and central in origin (CDI). The most frequent cause of acquired CDI is brain tumor and idiopathic forms represent between 20-50% of cases, depending on the series. Autoimmune hypophysitis is a rare cause of DI and is a presumptive diagnosis with a suggestive brain MRI and ACTH and TSH deficiencies as the most common hormonal involvement, although it can manifest ...

Background: The potential benefit of growth hormone (GH) therapy on health-related QOL (HQoL) of children with short stature related to GH deficiency (GHD) or smallness for gestational age (SGA) has not been well documented.Objective and hypotheses: Our objective was to assess potential disease and treatment related predictors for a poor HQoL in GH treated children. Children with male gender, SGA disorder, greater height deficit at start of GH and poor h...

Background: Paediatric hypertension is increasing and has been associated with obesity and insulin resistance. Recently, cortisol:cortisone ratio and the metalloproteinase 9 (MMP9), which is a marker of vascular remodelling, have been syndicated as new risk factors associated with hypertension.Objective and hypotheses: To analyse the association between paediatric hypertension with clinical, biochemical, inflammation, and vascular remodelling biomarkers<...

Background: Iodine concentrations in Chilean schoolchildren are the highest in South America. This may be related to excessive sodium intake, which is associated with hypertension. However, iodine decreases blood pressure (BP), which would be a cardiovascular protective factor.Objective and hypotheses: The objective of this study is to evaluate the effects of iodine on BP and cardiovascular risk factors, despite salt intake.Method:...
