Background: Placenta tissue hold great promise as a source of cells for regenerative medicine due to its plasticity and easy availability. Amniotic Mesenchymal Stem Cells (AMSC) represent a potentially unlimited source of functional pancreatic endocrine lineage cells, used to replenish the islet mass in diabetic patients.Objective and hypotheses: The aim of our study is to culture AMSC in serum-free condition preserving their phenotypic traits. These cul...

Background: In recent years, traumatic brain injury (TBI) has been identified as a significant cause of pituitary dysfunction in children. Paediatric prospective studies are rare especially for mild TBI.Objective and hypotheses: The aim of this present study was to evaluate the frequency of hypopituitarism after mild, moderate and severe TBI in hospitalized children, and determining factors of this deficiency.Method: A prospective ...

Aims: In children with new-onset type 1 diabetes mellitus (T1D), insulin dose regimens vary substantially. According to current ISPAD recommendations, the initial total daily dose (TDD) should range from 0.7 to 1.0 IU/kg BW/day. Adjusting TDD to achieve normal blood glucose concentration can take several days. The primary objectives of our INSENODIAB (INsulin SEnsitivity in New Onset type 1 DIABetes) study were to assess how patient characteristics influence i...

Introduction: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) rely on lifelong hormone replacement with hydrocortisone (HC). Alkindi® is the first HC licensed for children from birth to 18 years with AI, available in small doses of 0.5, 1, 2 and 5mg required for the needs of neonates, infants and children.Objectives: Primary: long-term safety of Alkindi®; Secondary: long-term d...

Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...

Background: The immunoglobulin superfamily member 1 (IGSF1) gene encodes a plasma membrane glycoprotein enriched in pituitary and testes. Loss-of-function mutations in IGSF1 cause an X-linked syndrome of central hypothyroidism (CeH), macroorchidism, and delayed pubertal rise of testosterone despite normal timing of testicular growth. This syndrome was discovered in patients with CeH; therefore, it is presently unknown whether IGSF1 mutations also cau...

Background: Insipidus diabetes is a rare disease in pediatric endocrinology.Objective and hypotheses: Facing a thickened pituitary stalk on MRI pituitary, the main diagnosis to mention are: dysgerminoma, histiocytosis, sarcoidosis, and autoimmune hypophysitis. Histiocytosis is a rare and often underdiagnosed cause.Method: We report the case of a teenage girl who presented polyuria–polydipsia syndrome at the age of 14 years con...

Background: H2O2 produced in large quantities in the thyroid may play a role in the pathogenesis of thyroid nodules and cancer. In vitro, moderate amounts of H2O2 are able to cause similar DNA damage compared to irradiation and even to induce RET/PTC rearrangements.Objective and hypotheses: We compared the defence mechanisms against H2O2 and irradiation in human thyrocytes, T-cell...

Context: Alkindi® (Hydrocortisone Granules, Diurnal Ltd, UK), was recently licensed for oral administration to children with adrenal insufficiency (AI) from birth to 18 years. Previously, children received compounded hydrocortisone to achieve age appropriate dosing, however almost 25% of batches were out of specification for mass and content uniformity and clinically evident under- and over-dosing was reported.Objectives: Primary: long-te...
