Background and Aim: Adult height predictions by the manual Bayley and Pinneau (BP) method in tall boys have shown large confidence intervals up to a bone age of 15 years. The adult height (AH) BoneXpert prediction method, which is based on an automated bone age reading, has not been evaluated in tall adolescents. We therefore compared the bias between the manual BP method and the BoneXpert (BE) method in tall male Flemish adolescents.Pat...

Background and aims. In several European countries, the incidence of primary congenital hypothyroidism (PCH) seems to increase in the last decade, especially in countries that have lowered the newborn screening TSH cutoff. In Flanders, two centers manage since 2012 the newborn screening for PCH and these maintained the same TSH assay (Delphia, Perkin Elmer) and cutoff (15 mU/l). We studied the current incidence and etiology of PCH and initiation of thyroxine treatment in Fland...

Obesity in adolescents is associated with increased risk of prediabetes and type 2 diabetes (T2D) and long-term complications in adulthood. Data regarding the effects of anti-obesity medications on glycaemic outcomes in adolescents are sparse. STEP TEENS (NCT04102189), a phase 3a, double-blind, placebo-controlled randomised trial in adolescents 12 to <18 years of age with obesity demonstrated that once-weekly subcutaneous semaglutide 2.4 mg provided a greater percentage red...

Background: Both undernutrition and chronic inflammation impair linear growth through resistance to GH. Fibroblast growth factor 21 (FGF21) is known as an important regulator of the metabolic adaptation to fasting. Elevated expression of FGF21, secondary to prolonged undernutrition has been identified to develop GH resistance and subsequent attenuation of skeletal growth and growth plate chondrogenesis in both mice and human. However, the mechanism of FGF21&#1...

Background: Adolescence is often a period of worse metabolic control and less wellbeing in diabetic children. We studied global (GW) and diabetic-related (DRW) wellbeing in diabetic adolescents and the influence of sex, age, ethnic origin, family composition (single- or two-parent family), family income and metabolic control.Method: 133 (71 girls, 120 autochthonous, 20 treated with CSII, 107 from a two-parent family, 68 from families with a monthly incom...

Background and Objectives: Early life might be a critical window for adiposity programming later in life. Metabolic profile in early life may reflect this programming and correlate with later life adiposity. We investigated if metabolic profile at 3 months of age is predictive for body composition at age 2 years and if there are differences between boys and girls and between infant feeding types.Methods: In 318 healthy t...

Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...

X-linked hypophosphatemic rickets (XLH) is the most common form of hereditary rickets. It is caused by inactivating mutations in the PHEX gene (phosphate-regulating-endopeptidase-analog, X-linked), leading to increased fibroblastic growth (FGF-23) levels, responsible for the renal phosphate wasting. This results in hyperphosphaturia and hypophosphatemia, and altered bone mineralization, in the absence of vitamin D deficiency. Classical treatment consists on oral supplementatio...

Background: Fatty liver disease is diagnosed increasingly in obese children, which pathophysiology remains unexplained. Risk factors as insulin resistance, evolution of steatosis and hypertriglyceridemia, should be taken into consideration in its development.Objective and hypotheses: To analyse the prevalence of hepatic steatosis identified by ultrasound, as well as features and anthropometric data in our population divided into 2 groups: with steatosis ...

Background: The incidence of paediatric papillary thyroid cancer (PTC) is increasing.Objective and hypotheses: To describe the clinical and histopathologic features at diagnosis, and follow-up of paediatric patients with PTC at Children’s Hospital of Mexico in a 10 years period.Method: Comparative longitudinal study. We included 22 paediatric patients with histopathologic diagnosis of PTC between 2004–2014, divided into r...
