Background: Carbohydrate counting is essential in diabetes management to match insulin doses to carbohydrate intake. Though recommendations concerning macronutritient composition exist (ISPAD Clinical Practice Consensus Guidelines 2022: Nutritional management in children and adolescents with diabetes), fat and protein intake is usually not calculated. Therefore, little is known if these recommendations are followed. Lower carbohydrate intake is reported to be ...

Background: Treatment of childhood and adolescent obesity is rarely effective if “cure” i.e., BMI below the obesity range, is used as the definition of success. However, results of obesity treatment is much more effective if treatment is initiated in 6–7 years old children. It is therefore urgent to develop interventions for young children, both preventive and obesity treatment efforts. Results from such interventions as well as preliminary results from ongoing ...

Background: Bone X-rays provide the main diagnostic parameters for chondrodysplasia, including common dyschondrosteosis (DC). Skeleton is usually studied piece by piece by visual analysis in search of characteristic signs. The phenotypic spectrum of DC is large. Indeed, children who have seemingly idiopathic short stature (ISS) may have subtle forms of DC that can be unrecognized.Objectives: Provide a user-friendly computer-assisted program that facilita...

Kallman syndrome is defined by the association of anosmia due to an agenesis of the olfactory bulbs and hypogonadotropic hypogonadism due to a GnRH deficiency which is currently explained by a deficit of GnRH neuron migration from the olfactory placode toward the hypothalamus. In fact, the X-linked form of KS is due to loss of function mutations in ANOS1 which encodes an extracellular protein (ANOSMIN) interacting with cell membrane heparin sulfate proteoglycans but a...

Background: Mirror movements (MM) are frequently associated to Kallmann syndrome (KS). They are mainly observed in patients with ANOS1 (KAL1) mutations. MM have never been reported in ANOS1 mutated females. A defect in the contralateral inhibition of the pyramidal tract has been proposed as the mechanism of MM in KS but never demonstrated.Objective and hypotheses: To investigate the molecular mechanism of a familial case of gonadotropic deficiency in whi...

Background: Vesico-ureteral reflux (VUR) is the most common urologic abnormality seen in children. It represents the backflow of urine from bladder to upper urinary structures due to a defect in closure of uretero-vesical junction. This condition predisposes children to repetitive pyelonephritis associated with renal scarring.Objective: Studies are continuously searching for the potential effect of VUR on growth. We aimed to assess growth indices: height...

Introduction: There are few published large-cohort studies examining the long-term impact of GNRH analogue treatment for precocious puberty (PP) on fertility in women. The PREFER study analysed fertility in a large cohort of women treated during childhood for PP with triptorelin.Methods: PREFER was a longitudinal, descriptive, non-comparative, epidemiological study conducted in 23 centres in France between February 2007 and November 2009. Women aged &#88...

Background: Patients with mutations of the short-stature-homeobox-containing (SHOX) gene likely have impaired growth, with or without a spectrum of skeletal anomalies consistent with mesomelic skeletal dysplasia. In a multinational clinical trial, GH has been shown to increase growth rate and final height (FH).Objective and hypotheses: The aim of this analysis was to describe FH outcome after GH treatment in an observational setting (Genetics and Neuroen...

Background: Severe GH deficiency (GHD) leads to several metabolic effects in the body ranging from abnormal body composition to biochemical disturbances such as high insulin sensitivity. However, less is known regarding these parameters in children with a milder deficiency in GH secretion.Objective and hypotheses: To analyse if short children with a relatively low GH secretion differ metabolically from healthy children of normal height.<p class="abst...

Context: Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,000 live births. In contrast to rare cases of syndromic monogenic CHTD, non-syndromic (NS) CHTD shows low familial recurrence risk (~2%) and low concordance rate between MZ twins, suggesting a two-hit scenario combining post-zygotic events with either a de novo monogenic mutation or incomplete penetrance of polyg...
