Background: Emotional and behavioural problems are often used in support of GnRH agonists therapy in girls with early pubertal timing. However, there is little evidence to show that CPP leads to psychological distress and whether treatment is associated with improved psychological outcome.Objective and hypotheses: The objective of this qualitative study was to explore the psychosocial impact of ICPP in recently diagnosed girls.Meth...

Background: T3-P-GD, a severe, rare disorder well known in adults, has not previously been described in children. It is characterized by persistently high serum fT3 concentration and normal, or even low, fT4 concentration during drug treatment. This condition is associated with very high titers of TRAb and large goiters, but its pathogenesis remains unclear. The recognition of this form of GD in children is of particular importance, as higher antithyroid ...

Background: Anorexia nervosa (AN), a state of chronic nutritional deprivation prevalent in children and young adolescents, is associated with major changes to the hypothalamic–pituitary axis including the GH–IGF1 axis, thyroid function, hypercortisolemia, and hypogonadotropic–hypogonadism, with delayed puberty and a low growth velocity (GV) at a time critical for the pubertal growth spurt, potentially affecting adult height. The effects of supraphysiological hum...

Introduction: Most patients with endocrine diseases diagnosed during childhood require long-term continuity of care. A lack of regular medical follow-up visits may be associated with impaired long-term health outcomes, with greater risks of morbidity and mortality. The importance and challenges of the transition from pediatric to adult healthcare are well recognized, but few studies have considered loss to follow-up during pediatric care. We investigated the p...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...

Background: An increase in the incidence of congenital hypothyroidism (CH) with a normally located gland has been reported worldwide. Affected individuals display transient or permanent CH during follow-up in childhood. We aimed to determine the prevalence of transient CH and to assess the possibility of distinguishing between transient and permanent CH in early infancy.Methods: This observational cohort study included all patients identified by systemat...

Background: Recently, mutations in the maternally imprinted MKRN3 gene have been associated to familial idiopathic central precocious puberty (iPPC). The clinical phenotype and the frequency of these mutations are poorly described.Objective and hypotheses: Delineate the frequency of MKRN3 mutations in iPPC and perform a genotype–phenotype correlation in MKRN3 mutated patients.Method: 59 index cases with iPPC have been included...
