Objective: To study how basal metabolism influences the somatometric evolution of the child and adolescent population with obesity in a pediatric endocrinology clinic; multichannel impedance study, TANITA BF 430.Results: 100 randomly selected patients from a database with 1400 records were studied. Most of the patients who come to these consultations for obesity are girls, between 8 and 11 years old. The group of boys at...

Transversal study. Patients from 0 to 17 years of age who had undergone an analytical determination of 25OHD during the year 2021 in our hospital were collected. The following were contrasted: 25OHD, PTH, total calcium, age, sex, reason for requesting analysis, time of year and country of origin. 25OHD ranges: normal >30 ng/mL, suboptimal 20-30 ng/mL and deficit <20 ng/mL; and normal PTH: 9-60 pg/mL.Results: 1. Prevalence of vitami...

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

The coronavirus disease (COVID-19) pandemic brought with it a state of alarm as of March 14, 2020, which implied a restriction on the mobility of the general population and home confinement. One of the main concerns raised by isolation was the substantial reduction in energy expenditure due to children spending more time sitting or participating in activities that involve very low rates of energy expenditure, such as watching television, managing the different networks social ...

Introduction: Pituitary stalk thickening (PST) is a rare condition in pediatric patients. As there are few studies published in pediatric population, the definition has been difficult to establish. The etiologies involved in PST can be divided in neoplastic, congenital, inflammatory/infectious or autoimmune diseases. In children the most frequent causes are neoplastic, followed by congenital lesions. The inflammatory/infectious and autoimmune diseases are rare...

Introduction: Diagnosis of growth hormone deficiency (GHD) and idiopathic short stature (ISS) is not straightforward. Nowadays growth hormone (GH) stimulation tests play a key role in the diagnosis but they are controversial due to the lack of normative data, poor reproducibility and poor disease concordance.The magnetic resonance imaging (MRI) is also a tool in the study of patients with short stature. Structural alterations of the hypo...

Introduction: Several studies showing a high prevalence of vitamin D deficiency in pregnant women have been published in recent years. Vitamin D deficiency during pregnancy has been related to adverse events both in mother and child. Plasma 25-OH vitamin D (25(OH)D) levels in the newborn are dependent on maternal deposits and show a close correlation with maternal levels; thus, neonates of vitamin D-deficient mothers present a greater risk of hypocalcaemia, rickets and a highe...

Background: Patients who have received an hematopoietic stem cell transplantation (HSCT) have more risk of endocrine complications (hypothyroidism, hypogonadism, and growth retardation) but the incidence of diabetes after HSCT is not as well known. The pathogenesis of the diabetes is not well established, and is believed to be multifactorial: chemotherapy, pancreatic irradiation, inflammatory cascade and cytokines, steroids and predisposing genetic factors.<p class="abstex...

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</...
