Birth chest circumference(CC) shows often, like birth gestational age(GA), tight direct relations to birth body weight(BW). However distinct connections of hypoxia/undernutrition with different body structures might be suspected based on brain-, heart- and adrenal-sparing following intrauterine growth restriction and, postnatally, on higher chest size for body mass observed at high altitude. Low BW and hypoxia may be associated with circulating Insulin-like Growth Factor-I(IG1...

Background: X-linked hypophosphatemia (XLH) is a rare genetic disorder of phosphate metabolism caused by mutations in the PHEX gene. XLH patients exhibit short stature and skeletal deformities, which are caused by defective bone mineralization site leading to increased porosity and decreased matrix stiffness. Bone mineral density measurements have been shown to be insensitive to the cumulative bone alterations. The velocity of the first arriving signal (vFAS) ...

Silver-Russell syndrome (SRS) is an epigenetic disorder characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The most common genetic abnormalities are 11p15 ICR1 loss of methylation, (11p15 LOM) and maternal uniparental disomy of chromosome 7 (mUPD7). There is little information on cognitive development in SRS patients and no neuroradiological studies are available so far. Global developmental delay and requirement for speech t...

Objectives: Continuous subcutaneous insulin infusion (CSII) has been associated with lower HbA1c. To explore whether CSII initiation leads to HbA1c improvement in each individual with type-1 diabetes and to identify co-variates which might influence change in HbA1c.Methods: 5,040 pediatric type-1-diabetes subjects (δ20 y, 49% boys, median age at diabetes onset [Q1;Q3]: 5.9 [3.5;8.4] years) ...

Background: Central precocious puberty (CPP) is defined as the secondary sexual characteristics onset before 8 years of age in females and before 9 in males, due to premature activation of the hypothalamic-pituitary-gonadal axis. The underlying cause remains idiopathic in the great majority; based on the 2009 Consensus, 2% to 7% of girls who have onset of CPP between the ages of 6 and 8 years have unsuspected pathology and only 1% have a tumor such...

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...

We describe a female neonate born from consanguineous parents who presented at birth with respiratory distress and severe hypoglycemia. At six months of age, the child was admitted to the Intensive care Unit because of two critical episodes characterized by fever and loss of consciousness. Child condition were critical and suggestive of sepsis, but blood tests showed severe hypoglycemia (19 mg/dl), hyponatremia (Na 132 mmol/l), compensated metabolic acidosis and increased infl...

Introduction: Oral/enteral caloric intake (KOE) insufficiency may accompany human newborn (NWB) respiratory derangements. We detected axillary temperature(TEMP) relations to NWB blood serum Insulin-like Growth Factor-II(IG2)-blood serum Insulin-like Growth Factor-Binding Protein-3(IB3) ratios(IG2/IB3R). Here we evaluate the TEMP-independent relevance of birth gestational age(GA) and KOE to relationships of O2 supplementation in respiratory gases(O2S) with IG2/...

Introduction: Human newborn(NWB) respiratory derangements may be concomitant to oral/enteral caloric intake (KOE) insufficiency. We evidenced a possible involvement of axillary temperature(TEMP) in relationships between preterm birth (PTB) and blood serum Insulin-like Growth Factor-I(IG1) in NWBs. Here we evaluate the TEMP-independent role of birth gestational age(GA) and KOE in relations of O2 supplementation in respiratory gases(O2S) to IG1 in the not-life-t...

Liquid chromatography associated with tandem mass spectrometry (LC-MS/MS) is currently considered the gold standard for steroid measurement. The aim of this study was to compare traditional immunoassay and LC-MS/MS methods for androgens measurement before and after human recombinant chorionic gonadotrophin (hrCG) stimulation in children with diagnosis of disorder of sex development (DSD) with 46,XY karyotype and past of normal testosterone secretion. We evaluated 19 patients, ...
