Background: The DNA-binding High Mobility Group Box-1 (HMGB1) is an intracellular gene regulator that can be secreted also in response to inflammatory mediators, including interleukins, binding subsequently to both RAGE and Toll-like receptors forming a self-reinforcing inflammatory circle. Cystic fibrosis (CF) is a condition characterized by chronic inflammation. Elevated serum HMGB1 concentrations were described in serum of obese children and to be associated with the metabo...

Background: Type 1 diabetes mellitus (1DM) is a common chronic disease of childhood. Treatment targets the best metabolic control in order to prevent long-term complications.Objective: To evaluate metabolic control in children and adolescents with 1DM along the years. Methods: Retrospective study including 1DM children and adolescents with more than 2 years of disease. Data were collected at 2005 and at 2012: sex, age at diagnosis, therapy in the last ye...

Background: Currently, the diagnosis of GH deficiency (GHD) in infants and young children is based on the assessment of GH serum levels either during hypoglycaemia or after pharmacological stimulation tests. However, GH cut-off values have not been standardized and provocative tests may be unsafe in this age range.Objective and hypotheses: Brain MRI may replace GH measurements in diagnosing GHD in infancy and young childhood.Method...

Background: MicroRNAs (miRNA) are small non coding RNA molecules, key regulators of metabolic pathways. Obesity is characterised by many metabolic changes. NAFLD is seen as a complication of obesity. FOXO-1, key regulator in insulin signalling, has been shown to be implicated in NAFLD. We previously identified miRNAs regulators of the FOXO-1 gene.Objective and hypotheses: To assess in serum whether the regulation of miR-146a and miR-486-5p, FOXO1 gene re...

Background: To evaluate the efficacy of thyroidectomy, it is necessary to know its complications; however, there is a great discrepancy in the literature regarding its incidence. A greater surgical aggressiveness achieves better control of the disease, but may be accompanied by more complications. Hypocalcemia is the most frequent potential complication after thyroidectomy, but its persistence can lead to serious systemic effects. The objective of this study i...

Introduction: The combination Down/Klinefelter syndrome was first described in 1959 by Ford. Its frequency is 0.4-0.9 / 10,000 newborn boys.Case presentation: A boy aged 5 y 4 m, born from a 2nd high-risk pregnancy (mother aged 44 with 1st pregnancy resulting in spontaneous abortion at 12 gestational weeks and with twice-established anemic syndrome) with (+) biochemical screening for Down syndrome. Birth was given via pl...

Background: POR deficiency is a rare form of congenital adrenal hyperplasia, transmitted in an autosomal recessive trait, that is characterized by ambiguous genitalia, impaired steroidogenesis and skeletal malformations similar to those of Antley-Bixler syndrome. It is caused by mutations in the P450 oxidoreductase gene (POR), an electron donor for all microsomal P450 enzymes including the three steroidogenic enzymes P450c 17 (17 alfa-hidroxylase /17,20 lyase)...

Introduction: Congenital hypothyroidism (CH) is classified as permanent CH (PCH) if levothyroxine (LT4) is life-long required, or as transient CH (TCH) if after LT4 discontinuation thyroid function remains normal. Early detection of TCH allows early discontinuation of LT4.Purposes: To identify predictors of TCH and PCH, and their cut-off value.Subjects and Methods: Retrospective st...

Background: There is no effective adjuvant therapy for patients with advanced ACT. YAP1, a HIPPO pathway effector, interacts with Wtn\beta-catenin pathway and plays a crucial role in the maintenance of postnatal adrenal cortex and regulates cell proliferation and apoptosis in several tissues. We recently showed that overexpression of YAP1 associates with worse prognosis in our cohort of pediatric ACT (pACT).Aim: To analy...

Background: Studies about thyroid function following hemithyroidectomy are scarce in the literature and no studies include pediatric population.Objective: To describe thyroid function in pediatric patients who underwent a hemithyroidectomy.Design: Retrospective cohort study.Patients and Methods: Among the 38 patients who underwent hemithyroid...
