Background: NKX2-2 gene mutation (reported in 3 cases worldwide) cause severe IUGR and neonatal diabetes. Beta-cells of the mice Nkx2-2 (−/−) model were recently shown to convert into cells producing the appetite-promoting peptide ghrelin. Classically, ghrelin secretion is stimulated during fast and suppressed by nutrients or glucose ingestion in all age groups. In obese children this ghrelin suppression reaches a minimum of 60% of base...

Background: Immunoassays are subjected to a number of interferences giving abnormal results which may lead to unnecessary investigations and treatment. We present clinical cases in which biotin treatment could be involved in abnormal results of thyroid function tests (TFTs) obtained by immunoassays based on biotinylated antibodies/analogs.Objective and hypotheses: Three infants were admitted to intensive care unit (ICU) during 2015, in Edmond and Lilly S...
