Background: Cohort SGA in North of Spain – EPIPEG.Objective and hypotheses: Establish a SGA cohort for monitoring, assessment catch-up, and analysis of middle-environmental and social factors.Method: We study live births in singleton pregnancies in our hospital during 2012–2014, and are classified according age gestation (EG) and weight/height (Spanish growth 2008). Visits were made at 0, 3, 6, 9, 12 months, with measurem...

Introduction: β-thalassemia is a chronic hereditary hemolytic anemia characterized by a defect in the synthesis of beta-globin chains, particularly common in the Mediterranean region, southern Asia, and the Middle East. Transfusion programs and chelation therapy have considerably extended the life expectancy of patients. This has led to an increase in the prevalence of complications related to iron overload, growth retardation is extremely common in polyt...

MOPD is known to be caused by homozygous loss-of-function mutations in a specific gene, PCNT. Both intra- and interfamilial clinical variability (even for the same variant) have been frequently observed, which makes it difficult to infer a genotype–phenotype correlation. Pericentrin (PCTN) is a structural protein expressed in the centrosome that plays a fundamental role in anchoring protein complexes, regulating mitotic cycle and thus cell proliferation. High levels of m...

Introduction: Short stature is a frequent reason for consultation in the paediatric age group. After appropriate clinical, radiological and laboratory evaluation, up to 60-80% of children are classified as idiopathic short stature (ISS) because no underlying cause can be found. Nowadays, the spreading of molecular is revealing that many of the patients initially classified as TBI, have variants in genes involved in the growth plate development. IHH gene is inv...

Introduction: Β-thalassemia is a chronic hereditary hemolytic anemia characterized by a defect of synthesis of beta-globin chains, particularly common in the Mediterranean region, southern Asia, and the Middle East. Chelation therapy significantly prolonged the life expectancy of patients. This has led to an increase in the prevalence of endocrine complications, linked to iron overload. Gonadal Dusfunction is a frequent complication in polytransfused beta...

Background: Homozygotes for the single nucleotide polymorphisms (SNPs) rs242941 and rs1876828 of the corticotrophin-releasing hormone receptor 1 (CRHR1) gene were previously associated with lower stimulated and basal cortisol levels respectively in asthmatic children on inhaled corticosteroids. Heterozygotes for rs41423247 of the glucocorticoid receptor (NR3C1) gene were found to have higher basal cortisol levels.Objectives</stro...

Adrenoleukodystrophy is an X-linked, inherited metabolic disorder. Here, we present 3 clinical cases of different phenotypes with one mutation in ABCD1 gene in one family.Patient 1: At the age of 9 years, manifestation of neurological symptoms was observed, skin color changed, these symptoms progressed monthly. MRI of the brain showed 13 points on Loes scale.During the examination, the diagnosis of X-linke...

Introduction: Acromesomelic Dysplasia of Maroteaux (AMDM) is a cause of severe short stature (final height below120cm) with shortening of the middle and distal segments of the limbs, caused by homozygous or heterozygous mutations in the NPR2 gene which encodes natriuretic peptide receptor B on chromosome 9p13Case report: The proband was 4y6mo old, second born to 3rd degree consanguineous parents and presented ...

Thyroid carcinoma in pediatric patients usually manifests as an asymptomatic neck mass, with a reported incidence of cervical lymphadenopathy that ranges from 35-83%.Multifocal involvement of the thyroid gland is a well-recognized feature of papillary carcinoma. The reported frequency is about 20%, with wide variations depending on the extent of the sampling and reporting by the pathologistA 12 year old boy presented with t...

Catch-up growth (CUG) is characterized by a period of supranormal height velocity following a transient period of growth inhibition. The two classical hypotheses on the mechanism are the neuro-endocrine hypothesis (a central mechanism that would recognize the degree of mismatch between actual size and target size) and the growth plate hypothesis (local regulation of growth according to a preset cellular program of senescence, characterized by decreasing growth proliferation ra...
