The pathogenetic role of genetic factors in congenital hypothyroidism (CH) is now widely known. The constant evolution of diagnostic methods in the field of medical genetics provides the opportunity to obtain an etiological diagnosis in CH patients with genetic defects in candidate genes. We performed genetic analysis by Next Generation Sequencing (NGS) of 18 candidate genes (DUOX2, DUOXA2, FOXE1, GLIS3, IGSF1, IYD, NKX2-1, NKX2-5, PAX8, SLC16A2, SLC26A4, SLC5A5, TG, THRA,...

Background: Obese children with and without Type 2 diabetes have periodontal disease that relates to systemic inflammation. There is limited data on periodontal disease in children with Type 1 diabetes (T1D).Aim: We aimed to assess periodontal disease markers and its determinants in children and adolescents with T1D.Materials and Methods: Cross-sectional study including 73 children...

In young girls, the occurrence of secretory ovarian cysts may be the first manifestation of Mc Cune Albright Syndrome. We reported the evolutive profile of 8 patients with peripheral precocious puberty (PP) with (n=5 cases) or without metrorrhagia (n=3). On the first episode, they were 3.8 years old (range 2.5 to 7.25 years), the average diameter of the ovarian cyst was 38.5 mm (range 25 to 88 mm), the mean estradiol level was 32.5 pg/ml (range 3 to 160), mea...

For the brain tumor committee of SFCE (Société Française des Cancers de l’Enfant).Objective: Therapeutic approach favors chemotherapy as the first-line-treatment in progressing OPG. There are few data on long term endocrine outcomes of aggressive OPG treated by upfront chemotherapy. Our main objective was to describe the long-term endocrine sequelae in these patients and to identify potential early predictors of the endocrine involvem...

Background: Familial glucocorticoid deficiency (FGD) is an autosomal recessive disorder characterized by specific failure of adrenocortical glucocorticoid production in response to adrenocorticotropic hormone (ACTH). Mutations of the nicotinamide nucleotide transhydrogenase (NNT) gene have recently been implicated in FGD.Objective and hypotheses: To describe a new case of FGD with combined mineralocorticoid insufficiency and extra adrenal manifestations....

Background: Brain MRI is an essential tool in the diagnosis of neuroendocrine disorders and aims at detecting anatomical abnormalities and tumors. However, it may lead to the identification of unrelated or questionably related abnormalities in the hypothalamic-pituitary region and/or the rest of the brain parenchyma.Objective and hypotheses: To establish the prevalence of causal lesions on brain MRI of children evaluated for hypopituitarism, assess the f...

Background: Epidemiological evidence in Europe indicates the increasing prevalence of premature puberty, especially in girls. This may be attributed to in utero and early-life exposure to environmental estrogen-like compounds present in pesticides, plastics (bisphenol A, phtalates …) and beauty products.Objective and hypotheses: The aim of this study was to assess the prevalence of premature thelarche (PT) and central precocious puberty (C...

Background: Congenital hypothyroidism (CH) is the most frequent endocrine disease in infants with prevalence ratio in the range of 1:2000–1:4000 new-borns. The disorder can be permanent (CHP) or transient (CHT). CH can be classified into two main groups: Dysgenesis, which accounts classically for 80–85% of cases and dyshormonogenesis for remaining 15–20%. From the last decade, studies described a upward trend for CH prevalence and changes in groups’ proport...

Introduction and Aim of the Study: girls with previous pediatric medulloblastoma (MB) are at risk of short stature and impairment of the hypothalamic pituitary gonadal function due to multiple risk factors;our aim was to assess the impact of hypergonadotropic hypogonadism (HH) on growth up to final height (FH) in females with or without growth hormone deficiency (GHD).Methods: anthropometrics (height-Ht-SDS, BMI-SDS, Tan...

Background: 17α-Hydroxylase/17,20-lyase deficiency is a rare form of congenital adrenal hyperplasia caused by mutations in CYP17A1, characterized by reduction of androgens, estrogens and cortisol production and mineralocorticoid excess.Objective and hypotheses: To describe the clinical and molecular characteristics of two sisters with 17α-hydroxylase/17, 20-lyase deficiency.Method: Two sisters, phenotypic females...
