Background: Growth monitoring of apparently healthy children aims at early detection of severe underlying conditions. Strong empirical evidence shows that current practices of growth monitoring are suboptimal. Practice standardisation with validated tools requires answering two questions: Which conditions should be targeted? How should abnormal growth be defined?Objective and hypotheses: To obtain consensus on a short list of priority target conditions o...

Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...

Background: Pituitary gland development is a well conserved process that starts with formation of Rathke’s pouch and specification of the primitive intermediate and anterior pituitary tissues. This early developmental sequence is conserved in humans compared to other mammals despite the fact that the human intermediate pituitary regresses during early gestation.Objective and hypotheses: We have identified the transcription factor Pax7 as key regulat...

Background: Early life stress (ELS) are known to have a deleterious impact on health, but their potential long-term consequences on mortality remain to be assessed. World War 1 (WW1) has caused major stress and bereavement to millions of European mothers.Objectives and hypotheses: To compare the effects of a maternal stress occurring during intra uterine or in postnatal life upon long-term mortality.Patients: Thanks to recently dig...

Background: The deciphering of the physiological importance of the GH secretagogue receptor (Ghsr), a G protein-coupled receptor (GPCR) depicted as the sole receptor of the pleiotropic hormone ghrelin, was initially compromised by the modest phenotype observed in Ghsr−/− animals. This lack of a robust response to total loss of Ghsr may result from developmental compensatory signals. Still, the description of rare mutations in the GHSR p...

Background: Final height (FH) is reduced in congenital adrenal hyperplasia (CAH), due both to overtreatment by hydrocortisone therapy and to advanced epiphyseal closure linked to hyperandrogenism by Hydrocortisone therapeutic insufficiency.Objective and hypotheses: To evaluate the efficacy and safety of the addition of an androgen receptor competitor and an aromatase inhibitor to reduced hydrocortisone doses.Method...

Background: Bartter syndrome represents a rare severe condition, autosomal recessive, corresponding to several genes, characterized by an illness of the renal ascending branch of the handle of Henle. Only 15 cases of BSHPT have been communicated, either in publications or orally, but none presented such severe bone manifestation as ours.Objective and hypotheses: To present bone features of two patients suffering from severe BHSPT, so as the therapeutic a...

Background: Leprechaunism, due to a mutation of both alleles of insulin receptor gene, is a most severe and precociously life-threatening condition, difficult to treat.Objective and hypotheses: In leprechaunism rhIGF1 may replace insulin through I the insulin-like metabolic properties of its own receptor.Method: rh IGF1 was continuously subcutaneously administered through a.pump from the age of four months and adjusted according to...

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: Congenital isolated ACTH deficiency (IAD) is a rare inherited disorder that is clinically and genetically heterogeneous. Patients are characterized by low or absent cortisol production secondary to low plasma ACTH despite normal secretion of other pituitary hormones and the absence of structural pituitary defects. Mutations in the TBX19 gene, a T-box factor selectively expressed in developing corticotroph cells, have been identified so far only in cases of neonatal...
