Introduction: Developing an acute onset thyroid nodule is rare in children and usually associates with infectious or neoplastic disease; when linked to hyperthyroidism, the most likely diagnosis is toxic adenoma.Clinical description: 9-year-old boy with no relevant medical history was seen at the emergency department for acute cervical pain and tumor involving the left thyroid lobe with no inflammatory signs or history of trauma. Physical examination rev...

Introduction: Thyroid dyshormonogenesis is a heterogeneous group of hereditary diseases produced by the total/partial blockage of the biochemical processes involved in thyroid-hormone synthesis and secretion. Many genes are involved in this process. PAX8 is a transcription factor essential for thyroid-gland morphogenesis and synthesis of thyroid hormones, since it activates TG, TPO and TSHR gene transcription. More than 50 PAX8</...

Introduction: Diabetes insipidus (DI) is a rare disease in children. In most cases it is acquired and central in origin (CDI). The most frequent cause of acquired CDI is brain tumor and idiopathic forms represent between 20-50% of cases, depending on the series. Autoimmune hypophysitis is a rare cause of DI and is a presumptive diagnosis with a suggestive brain MRI and ACTH and TSH deficiencies as the most common hormonal involvement, although it can manifest ...

Introduction: Dumping Syndrome (DS) has been recognized as a major complication of Nissen fundoplication in young children. Althougth other causes have been recognized. We describe a children with esophageal atresia who presented with late DS caused by a surgical complication, Dumping and Horner syndrome were diagnosticated after his surgery.Case description: A male newborn with prenatal diagnosis of right Aortic Arch was born by vaginal delivery, radiol...

Introduction: Growth hormone deficiency (GHD) is the most frequent endocrine deficit in childhood survivors of brain tumours. However, there is insufficient evidence to guide the timing of growth hormone replacement (GHR). At Great Ormond Street Hospital timing is based on clinical need rather than in relation to oncological treatment. Therefore, sufficient variability in GHR timing is available to analyze its effect on tumour progression and recurrence.<p...

Background: Iodine deficiency is the main cause of endemic goitre. A total of 29.8% of the world’s school-age children insufficient iodine intake. A population is deemed iodine-sufficient when median iodine levels are over 100 μg/l; measured iodine deficiency serves as a diagnostic criterion for determining the extent to which goitre is endemic, and also as an indicator of the gradual eradication of iodine-deficiency disorders.Patients, materia...

Background: A second screening for congenital hypothyroidism between the 2nd and the 4th weeks of life in preterm infants is recommended in order to avoid false negative on the first screening. The incidence of transient hypothyroidism in this population is high.Objective and hypotheses: i) Analyse the utility of the second screening in our population of preterm infants. ii) Follow-up of those preterm infants with hypothyroidism.Me...

Background: Epigenetic alterations due to maternal obesity may contribute to an increased metabolic risk in the offspring. IRS1 has a critical role in insulin signalling and its methylation has been previously associated with body fat distribution and glucose metabolism in human adipose tissue. The relationship between IRS1 methylation in birth tissues and obesity parameters in the offspring is unknown.Objective: To iden...

Introduction: Pituitary adenomas (PPAs) are uncommon in childhood and adolescence, accounting for 2-6% of all intracranial neoplasms. Most data are based on case reports and only a few series have been reported. Delayed puberty, short stature, galactorrhea and weight gain are common features at presentation in pediatric patients. Functional tumors constitute a vast majority (90%) of PPAs including corticotropinomas in the first decade followed by relative upsu...

Introduction: Both the innate and adaptive immune responses are deregulated in individuals with obesity and are a key driver of its associated metabolic alterations. Although the anti-inflammatory growth differentiation factor 15 (GDF-15) is a candidate protein against obesity, its mechanisms regulating the immune responses are not fully understood.Methods: We examined whether serum GDF-15 was related to serum levels of ...
