Objective: Premature GH treatment discontinuation of SGA is usually linked to safety or ineffectiveness. However, this population is poorly addressed compared to those with final adult height (FAH). Authors investigated the journey of SGA prematurely discontinued Norditropin® treatment in a French real-life.Methods: Observational prospective ongoing study: 291 Norditropin®-treated SGA. Annual FU up to FAH. Descriptive anal...

Objective: Bang et al. showed that Δ height and growth velocity (GV) the first year of treatment could be predictive factors of statural response in SGA (n=54). Poor responders showed GV <1SDS (55%) and Δ height <0.5SDS (45%). Moreover, Ortego et al. seems to confirm the suitability interest of KIGS mathematical model in a retrospective SGA cohort (n=103) showing that the percentage of good responders in the first year varies betwee...

Background: Silver-Russell syndrome (SRS) is a heterogeneous syndrome characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The major abnormality is the hypomethylation of paternal allele of 11p15 imprinting centre region 1. In 10% of cases a maternal uniparental disomy of chromosome 7 (UPD7) can be detected. Speech delay and learning difficulties have been reported in these patients.Objective and hypothes...

Background: In spite of many studies demonstrating efficiency of recombinant growth hormone (rGH) on adult height in children born small for gestational age (SGA), great variability of response exists between treated patients. Predictive factors have been already studied such as age at start of treatment, rGH dose,…, but few data are available regarding the predictive values of pretherapeutic data on growth response.Objective and hypotheses: The ma...

Background: ‘Dead in Bed syndrome’ mechanism in childhood diabetes remains unknown. The hypothesis is that a nocturnal hypoglycaemia could lead to arrhythmias related to abnormal ventricular repolarisation.Objective and hypotheses: To look for a relationship between spontaneous fluctuations of nocturnal glycaemia, ventricular repolarization and heart rate variability (HRV) in prepubertal children with type 1 diabetes.Meth...

Background: Turner syndrome (TS), affects approximately 1/2500 live female births. The clinical features range from a severe phenotypic character to reduction of final height and premature ovarian failure.Objective and hypotheses: Processing of sensory information from visual, vestibular and somatokinesthetic systems is required to organize an adequate motor response aiming at gaze and posture stabilization according to the expected task and to the envir...

Background: Congenital adrenal hyperplasia (CAH) is a rare chronic disease diagnosed and treated from birth. Hormone replacement therapy is essential to lead a normal life and must be adapted to stress. Poor compliance to treatment or inefficacy is life threatening leading to high risk of by dehydration and hypoglycaemia.Objective: The objective of therapeutic education sessions is based on the skills needed for regular intake of pills and recognition of...

Background: Isolated hypoaldosteronism is an autosomal recessive inherited disorder of terminal aldosterone synthesis, leading to selective aldosterone deficiency. Two different biochemical forms of this disease have been described, called aldosterone synthase deficiency or corticosterone methyl oxydase, types 1 and 2. In type 1, there is no aldosterone synthase activity and the 18 hydroxycorticosterone (18 OHB) level is low, whereas in type 2, a residual activity of aldostero...

Introduction: Pseudohypoparathyroidism (hereafter named iPPSD for inactivating PTH/PTHrP Disorder) is a rare disease characterized by hormonal resistance including PTH, subcutaneous ossifications, short stature, brachymetacarpy and early onset obesity. iPPSD type 2 and 3 are caused by genetic or epigenetic variations in the GNAS gene or its promoters. Although uncommon features have been identified such as severe asthma or sleep apnea, digestive manifestations...

Background: ‘Thelarche variant’ (TV), also known as ‘unsustained/slowly progressive puberty’ or ‘exaggerated thelarche’, is a term used to describe girls with premature thelarche and intermediate features between isolated premature thelarche (PT) and central precocious puberty (CPP). Despite being characterized by a FSH predominant response and by a peak LH response <5 IU/L to GnRH test, a univocal definition is lacking.<...
