Background: Adult height prediction models (AHP) were designed several decades ago based on the Caucasian population, hence they are not adapted to our population’s characteristics and secular changes. Technological advances have improved the accuracy of bone age (BA) reading through automated analysis, which has been incorporated into new AHP models, but have not been evaluated in the Mexican population.Objective:...

Background: The growth process that transforms a newborn into an adult implies that there is not only an increase in height but above all a constant change in body proportions. Knowledge of the body proportions gives insight into the natural process of maturation and any disturbance can be used as a diagnostic tool.Objective and hypotheses: Manual measurement of body dimensions is a highly time-consuming procedure requiring a variety of measurement tools...

Background: Although motor performance is often impaired in patients with Turner syndrome, the exact prevalence of motor problems is unknown. Detailed studies on specific motor profiles are lacking and the exact relationship between performal IQ and motor function is unknown.Aims and objectives: 1. To describe motor performance in our population of children and adolescents with Turner syndrome including the differentiation in specific motor skill domains...

Introduction: The diagnosis of GHD requires the coexistence of anamnestic, auxological and laboratory data. The latter are burdened by the poor accuracy and adverse effects of the stimulation tests. A recent european audit (Horm Res Paediatr 2019;92(3): 150-156) on GH diagnostic reported as preferred tests in Italy Insulin tolerance test (ITT), glucagon, clonidine, arginine and Arg-GHRH. We conducted a survey to explore which of them are most used in It...

Background: The BoneXpert method for automated determination of bone age (BA) from hand X-rays was introduced in 2009, covering the Greulich-Pyle BA range up to 17 years for boys and 15 years for girls.Objective and hypotheses: To present an extension of the BA range of the automated method up to 19 years for boys and 18 years for girls and to validate it against manual rating.Method: The extension was developed based on images fro...

Background: The assessment of bone age increments is important when monitoring treatment in many conditions in pediatric endocrinology. However, manual rating suffers from significant rater variability. Automated bone age assessment could provide increased precision, and also assess increments of bone health index (BHI) from the same X-rays.Objective and hypotheses: To assess the precision of automated assessment of increments of bone age and BHI.<p ...

Introduction: Abdominal subcutaneous adipose tissue (SAT) is subdivided into two depots by the fascia of Scarpa. The deep SAT (dSAT) and superficial SAT (sSAT) are morphologically and metabolically distinct, with dSAT reportedly being more similar to visceral adipose tissue (VAT) in terms of elevating the risk for obesity-related complications. Conversely, sSAT appears to be more similar to lower-body SAT. The relationship between dSAT and metabolic disease ha...

Background: Glucokinase (GCK) acts as the glucose sensor of β-islet cells, regulating insulin secretion in response to changing glucose concentrations. Homozygous GCK mutations are a rare cause of permanent neonatal diabetes. Heterozygous mutations lead to GCK MODY, causing mild hyperglycaemia, not usually requiring treatment.Case: The index case was born to consanguineous parents at 36+2 weeks gestation, weighing 1610 g (0.4th centile). Hy...

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...

Context: Olfactory bulb (OB) and eyeball size change depending on age and puberty. There is well-established trade-off between sensory structures of brain such as eye and olfactory bulb.Objective: The aim of this study is to analyze the potential reciprocal changes between OB and eyeball volumes (EV) in girls with precocious puberty (PP), as a sign of early pubertal onset.Design: A...
