Purpose: To track the effects of growth hormone on bone geometry and maturation in children with isolated growth hormone deficiency (GHD).Methods: 299 left hand X-rays from 77 short prepubertal children (54 boys and 23 girls) with isolated GHD were analysed for changes in metacarpal thickness, width, length, medullary diameter, the Bone Health Index (BHI) and bone age (BA) from one year preceding until four years after s...

The Polycomb Repressive Complex 1 (PRC1) represses gene expression through CBX2, which binds to H3K27me3 and promotes chromatin expression. Recently, CBX2 has been shown to function in testis-formation by directly repressing Wnt4's downstream target, Lef1, in Sertoli cells rather than positively controlling Sry expression, as previously thought. Here, we describe two new cases carrying missense mutations in CBX2. The first is a female with 46,XY ...

Context: Delayed TSH elevation (dTSH) is defined as elevated TSH in the second neonatal screen following normal TSH in the initial screen. The clinical outcome of newborns with dTSH is not entirely elucidated, although several studies have suggested a full recovery in most cases.Objective: We aim to elucidate the natural history of dTSH in a group of neonatal intensive care newborns. In addition, we aim to define clinica...

Introduction: Hyperglycemic hyperosmolar state (HHS) and diabetic ketoacidosis (DKA) are life-threatening emergencies in diabetic patients. While DKA at presentation of T1D in children represents about 25% of cases, HHS is very unusual as a first presentation.Case: A 10 year old Haitian-Sudanese boy presented to our ER for obtundation. He had a 10 day history of polydipsia and polyuria followed later by vomiting, for...

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,500 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 polygenic inherited variants,. As this l...

Objective To study a large Chinese family with Type A Insulin Resistance Syndrome (TAIRS) and the members’ clinical phenotypes. Explore their genotype-phenotype relationship between environmental factors and hereditary features. Methods 19 members of the family were investigated for their past history, dietary habits and living habits. PCR and Sanger sequencing were applied to detect mutations of the INSR gene among 6 core members from the Pedigree. Besides, fasting blood...

Introduction: People’s weight-related behaviors may be influenced by their personal social network (SN), notably via family and friends’ behavioral modelling and motivational social support (SS).Objective: We examined the cross-sectional relation between social network-based social support (SS) and weight-related outcomes among adolescents ina pilot study within the QUALITY cohort, a longitudinal study investigating the natural...

Background: A high rate of hearing impairment has been reported in patients with congenital hypothyroidism (CH). However, this association has only been explored in a few studies with inconclusive findings.Objectives: To assess the prevalence of hearing impairment among patients with CH and determine whether hearing impairment is related to delay in supplemental therapy, etiology of CH or other parameters.Methods: Audiometry was un...

Background: Nocturnal hypoglycemia is not regularly predictable on the basis of a bedtime BG level and can only be confirmed by BG tests at regular intervals during the night or continuous glucose monitoring (CGM).Objective and hypotheses: A bedtime snack containing carbohydrate as well as fat and protein may be useful in preventing nocturnal hypoglycemia, but this should not be at the expense of high overnight BG levels. In many individuals, a lowering ...
