Background: Low birth weight, unfavourable intrauterine conditions, and post-natal catch-up growth are associated with a subsequent impact on growth and pubertal development. Start of puberty is genetically determined but might be altered due to environmental influences.Objective and hypotheses: In a longitudinal study we observed genetically identical twins with intra-twin birth-weight (bw) differences from birth until puberty.Met...

Background: Low birth weight, unfavourable intrauterine conditions, and post-natal catch-up growth are associated with a subsequent impact on growth, pubertal development, and metabolic disturbances later in life. Although the start of puberty is genetically determined it might be altered due to environmental influences.Objectives: In a longitudinal study (birth to final height) we observed growth and pubertal development of genetically identical twins b...

Background: Adipocyte fatty acid binding protein (aFABP) regulates intracellular transport of fatty acids and seems to be involved in the pathogenesis of the Metabolic Syndrome. aFABP overproduction leads to increased cholesterol and triglyceride accumulation and to higher expression of pro-inflammatory genes. In adults aFABP seems to promote insulin resistance and atherosclerosis, and aFABP levels are significantly higher in obese compared to lean subjects. Fat mass, lipid ma...

Background: The hCG stimulation test is a valuable method for assessing androgen production but there is a need to explore its utility in assessing androgen responsiveness and long-term prognosis.Objective and hypothesis: Our aim was to explore the effect of hCG stimulation on the peripheral transcriptome in boys undergoing investigation for DSD.Method: Thirteen boys undergoing investigation for 46,XY DSD received i.m. hCG 1500 U o...

SHOX deficiency causes a spectrum of clinical phenotypes related to skeletal dysplasia and short stature, including Léri-Weill dyschondrosteosis, Langer mesomelic dysplasia, Turner syndrome, and idiopathic short stature. SHOX controls chondrocyte proliferation and differentiation, bone maturation, cellular growth arrest and apoptosis via transcriptional regulation of its direct target genes NPPB, FGFR3, and CTGF. However, our u...

Have a real increase in precocious and advanced puberty with COVID19? Retrospective observational analytical study in which we compared the incidence of first consultations made by early thelarchies between the months of March to December 2019 and between March and December 2020 at the Pediatric Endocrinology(PE)consultation in our hospital, and the increase in diagnosis of precocious puberty (PP)and advanced puberty (PA) in the cases evaluated for this reason, with the aim of...

Background: Nonimmune neonatal goitrous hypothyroidism is a rare cause of neck mass and stridor. Retropharyngeal extension, described in 7% of cases of goitre spreading outside the thyroid bed, represents a diagnostic dilemma that requires a systematic multimodality imaging approach combined with hormonal and genetic analysis. We report the case of a one-week-old baby who presented with stridor and respiratory distress, without palpable neonatal goitre and whose biochemical pr...

Background: Granulosa cell tumors (GCT) originate from sex cord/stromal tissue in the gonad. They are typically located in an ovary, but extra-gonadal localisation exists. These tumors are extremely rare in children and no systematic review has been published. The objective of this systematic review is to examine the following questions: What is the clinical picture of girls with a GCT? How are these patients treated and what is their prognosis?<p class="a...

NASH is an increasingly relevant finding in the pediatric population affected by obesity. In adults, its evolution from this steatosis to fibrosis and its correlation with metabolic syndrome is increasingly significant. The existence of a rapid and validated screening tool in consultation would be very useful.Main objective: To evaluate if the measurement of intraperitoneal fat measured through nutritional ultrasound, allows the diagnosi...

Objective: Observe in children born SGA the relationship that the different variables have in the evolution towards metabolic syndrome, adrenarche and/or early/advanced pubarche or short stature and treatment with GH.Material and Methods:A retrospective observational study analyzing in SGA children at birth (n=103) and who are currently between 7-9 years of age, variables such as: sex; “Catch UP&r...
