Background: The thyroid disorders in children and adolescents are varied. They are dominated by frequent malignant tumour lesions and goitres represented by Graves’ disease and Hashimoto’s thyroiditis in adolescence. They are characterized by several clinical forms.Objective and hypotheses: To study the clinical and aetiological characteristics of thyroid disease in children and adolescents.Method: This is a retrospective...

Background: The hypothyroidism is defined by an elevated TSH with normal fT4 and the absence of symptoms of hormonal deficiency. In children and adolescents, it is mainly due to chronic thyroiditis or radiotherapy for cervical cancer.Objective and hypotheses: Assess clinical, etiological and evolutionary characteristics of subclinical hypothyroidism in children and adolescents.Method: This is a retrospective and prospect...

Background: Achondroplasia is the most common cause of genetic dwarfism with a prevalence of 1/10 000 to 30 000 birth. It is a pathology of dominant inheritance linked to the mutation of the receptor gene growth factor on chromosome 4p16 fibroblastes FGFR3 responsable rhizomelic dwarfism and multiple complications likely to compromise the functional and vital prognosis of patients.Objective and hypotheses: Find the frequency of neurological complications...

Background: PEA is a rare disease characterised by the coexistence of two endocrine autoimmune deficiencies, sometimes with a non-endocrine autoimmune disease associated concomittente of occurrence or metachronous way. Depending on the age of onset of the disease and the characteristics observed, we can distinguish several subgroups.Objective and hypotheses: Search frequency of PEA in children and adolescents and study their phenotype.<p class="abste...

Background: Small gestational age (SGA) is defined by a small size and/or a birth weight <−2 DS/standards for the term of pregnancy. Most of these children catch up to their size in the first 2 years of life. Only 10% of them will stay with a size of <−2 DS. These children may benefit from treatment with GH, which improves their stature prognosis.Objective and hypotheses: Study the final height of children with IUGR have reached adult...

Background: Trisomy 21 is a chromosomal abnormality that predisposes to autoimmune diseases. Among them the thyroid dysfunction is frequently observed.Objective and hypotheses: Study the various thyroid diseases in trisomy 21 patients and their therapeutic management.Method: This is a retrospective study of 50 cases of Down syndrome children with thyroid disease, collected over a period of 9 years (2006–2015). All children und...

Background: Ovarian tumors are rare in the pediatric age and are represented primarily by functional cysts and benign tumors, the most common is the mature teratoma.Objective and hypotheses: Assess clinical, radiological, etiological and scalable characteristics of ovarian tumors in the pediatric age.Method: Retrospective study of seven cases of ovarian tumors collected over a period of 20 years. All children received complete clin...

Background: Central precocious puberty (CPP) in girls is characterized by an activation of the hypothalamic–pituitary–ovarian (HPO) axis before 8 years of age. Given the gradual awakening of the GnRH pulse generator, a spectrum of presentations has been found among girls with premature sexual development. CPP are not easily distinguished from idiopathic precocious thelarche (PT) or other intermediate positions along this spectrum. The GnRH test is the gold standard t...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...

Background: Congenital adrenal hyperplasia (CAH) is a pathology with a genetic deficiency of one of the enzymes of steroidogenesis. It is due to 21 –Ohase deficiency in 90–95% of cases. The complete deficiency of this enzyme is responsible for the classic form (sexual ambiguity at birth with or without salt loss). While the partial deficiency results in a polymorphic clinical presentation occurring in childhood or adolescence. In rare neglected cases, the diagnosis i...
