Introduction: The incidence of Cushing disease (CD) is 0.7-2.4/year per million, andadolescents and children make up 10% of new cases annually. However, thesensitivity and specificity of tests used to diagnose CD in childhood may bepoor, resulting in difficulties in diagnosis and treatment. The aim was to reportpediatric CD patients attending our pituitary referral center for surgery and todescribe their diagnosis, treatment and long-term follow-up.<p clas...

Introduction: Fulminant type 1 diabetes (FT1D) occurs because of a sudden and almost total destruction of pancreatic β-cells, triggered by a viral infection. FT1DM may cause diabetic ketoacidosis (DKA) and even sudden death. Thus prompt diagnosis is vital.Case Report: Antibiotic treatment was started for a 4-year-old female patient because of a fever and cough. On the second day of treatment, she was admitted with r...

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...

Objectives: Modern treatments lead to increased survival rates from childhood cancer. Childhood cancer survivors (CCS) are a growing population group, which is at high risk for cardiometabolic disorders including metabolic syndrome, type 2 diabetes and cardiovascular disease. Obesity is one of the major drivers of these adverse outcomes, resulted from corticosteroids, radiotherapy, sedentary behavior, and precancer obesity. Assessment of obesity could identify...

Introduction: The good nutritional status of children in the first years of life is essential for their healthy growth and development. Evaluating the repercussions of nutritional status is fundamental since nutrition can influence both short-term and adult life.Objective: To analyze the temporal trends of the BMI of Brazilian children aged 0 to 5 between 2010 and 2022.Patients and methods:...

Aim: The most common cause of persistent hypoglycemia and related brain damage in infancy is congenital hyperinsulinism (CHI), due to inappropriate secretion of insülin by pancreatic βcells. The most frequent and most serious mutations are activating mutations in ABBC8 or KCNJ11 genes. Genetic analyses, which might predict the type of lesion, performed in early period and 18f dopa pet scanning are very valuable for treatment choice and follow-up of the patients. In t...

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Background: Anti-Müllerian hormone (AMH) is produced by granulosa cells in small follicles prior to gonadotropin dependent growth and serum levels reflect the number of small antral follicles. There are currently no longitudinal data of individual AMH levels from infancy to adolescence.Aim: To evaluate whether AMH in infancy and childhood is associated with AMH levels and ovarian morphology peripubertal and in adole...

In XLH, excess fibroblast growth factor 23 (FGF23) causes hypophosphatemia and consequent rickets, skeletal deformities, and growth impairment. The efficacy and safety of burosumab, a fully human monoclonal antibody against FGF23, was evaluated in two Phase 2 trials in children with XLH. In CL201, 52 children with XLH (5–12 years old, Tanner ≤2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) weeks, with doses titrated up to 2 mg/kg to...

Background: Growth during infancy is a continuation of the rapid fetal growth and its regulation is complex and multifactorial. It is well-established that insulin-like growth factor-I (IGF-I) and its regulators (e.g. IGF binding proteins (IGFBP-3) and pregnancy-associated plasma protein-A2 (PAPP-A2)) are important for prenatal and postnatal growth; however, their significance for growth during infancy is not fully explored.Aims: The aim...
