Introduction: The Immune Thrombocytopenic Purpura (ITP) and Graves Disease (GD) have in common an autoinmune physiopathology. ITP is characterized by a platelet count less than 100 × 106/l in the absence of other cause. On one hand, ITP has been associated with thyroid dysfunction, without developing GD. On the other hand, GD might develop with moderate thrombocytopenia, generally more than 100×109/l. It is described that in most cases ITP might...

Neonatal diabetes is characterised by hyperglycaemia in the first 6 months of life. Transient neonatal diabetes (TND) is differentiated from permanent neonatal diabetes by its remission in infancy/early childhood, with possible relapse during adolescence in 50% of the cases. Incidence of neonatal diabetes is thought to range from 1:90,000 to 1:160,000. A gene mutation affecting pancreatic beta cells synthesis/secretion of insulin is present in more than 80% of the cases. Overe...

Objective: The aim of this study was to evaluate the difference between the incidence of hypoglycemia in those preterm newborns who were exposed to steroids and those who were not.Methodology: This is a prospective cohort study of preterm infants born between 2017 and 2018 at a gestational age of 26 to 34 6/7 weeks in the Hospital Universitario de Santander- HUS- in Bucaramanga, Colombia.Results: 128 preterm infants were e...

Background: Gonadal function is altered up to 25% in patients who suffered cancer in childhood. Cryopreservation of ovarian tissue (COT) is an option for preserving fertility.Aims and objective: To establish the prevalence of primary hypogonadism (PH) in children with cancer after hematopoietic cell transplantation (HCT). To analyse the variables that predict progression to PH.Methods: Retrospective cohort study. Patients aged 0 to...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Background: The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase deficiency, which in its severe form can cause genital ambiguity in females. This can be ameliorated by administering dexamethasone to the mother.Case: This is a family whose index case is a first son diagnosed by Madrid Newborn Screening Program of CAH with salt-wasting form due to 21-hydroxylase deficiency. Mutation analysis revealed: ‘hybrid deletion’ ...

Introduction: Physical activity (PA) is one of the treatments to promote weight loss in children with obesity. The WHO advices to perform moderate to vigorous (MV) PA during 60-min daily. It is necessary to measure the effect of increasing PA and the adherence to therapy.Aims: To evaluate PA using accelerometry at the onset and after 8 weeks of treatment with nutritional intervention and increase in PA.Patients, material and method...

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

Background: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Persistent hypoglycemia places patients at risk for adverse clinical outcomes, and current guidelines recommend maintaining plasma glucose >3.9mmol/l. CHI patients often have substantial, residual hypoglycemia and fail to meet treatment goals with currently available standard of care (SOC) therapies. In this study, we aimed to characterize...

Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in infants and children. In the past 20+ years there have been tremendous advances in the understanding of the molecular genetics of HI, including the discovery of the mechanisms responsible for a focal form of the disease that can cured surgically. However, treatment options for non-focal HI continue to be limited, with only one drug currently approved for this indication. As a result of delay...
