Introduction: The incorporation of the interstitial glucose monitoring system, in the offer of services in the Andalusian Public Health System (APHS), means an opportunity for the implementation of a model of integration, and follow-up of glucose data, and the evaluation of their impact in health results.Purpose (Aim): The design and implantation of a model that allows the identification, registration of clinical data, i...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

Background: Primary adrenal insufficiency (PAI) is a rare life-threatening disorder. Data on PAI in children are scanty, with the exception of Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD).Objective and hypotheses: Evaluate etiology of PAI in a large cohort of children and characterize clinical presentation in subjects with PAI not due to 21-OHD.Method: Children followed in eight tertiary centers wer...

Background: There is growing evidence of a correlation between fat and bone metabolism at both the clinical and molecular levels, although the systemic regulators have not been clearly identified. The receptor activator of nuclear factor kB ligand (RANKL) and its soluble decoy receptor, osteoprotegerin (OPG), are involved in bone resorption and vascular calcification. OPG levels has been related with insulin resistance in adult obese subjects.Objective a...

Background: Ovotesticular Disorder of Sex Development (OTDSD – true hermaphroditism) is rare, characterized by the presence of both presence of both testis and ovay tissue. Usually, these patients seek medical attention due to ambiguous genitalia.Case presentation: A 15-year-old boy, with ‘atypical’ genitalia and breast enlargement came for surgical correction. His genitalia had a more masculine aspect at birth and he had been submitted to...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...

Introduction: Children with Prader-Willi syndrome present with short stature and obesity. However, very little is known about the role of this imprinted control region in the general population. This study aims to analyze the methylation status of the PWS imprinting control region (ICR) in placenta and its association with postnatal growth and obesity parameters in healthy children.Methodology: The methylation percentages of the PWS-ICR ...

Background: Infants with Prader-Willi syndrome (PWS) exhibit stunted growth. However, little is known about the role of genes expressed from the imprinted PWS domain in healthy infants. This study aimed to analyze the relative gene expression of the SNURF-SNRPN/UBE3A cluster in the imprinted PWS domain in umbilical cord tissue, and its potential association with prenatal and postnatal growth in apparently healthy infants.Methods:...
