Background: T1D concordance in MZ twins being ~40%, non-heritable factors play a major causal role in this autoimmune disease. T1D has recently increased in young European children. Collecting prospective environmental data in a cohort of millions children-years starting soon after birth seems unpracticable. Retrospective case-control studies are an alternative, provided biased controls and recall bias can both be avoided.Objectives: To develop a ‘v...

Background: DEND syndrome is characterized by developmental delay, epilepsy, and neonatal diabetes mellitus (NDM) due to mutations in KCNJ11 and ABCC8 genes. Intermediate DEND (iDEND) syndrome is a rare mild form with mild motor, speech or cognitive delay and an absence of epilepsy. Improvement in glycemic control and neurologic symptoms has been reported in three cases with iDEND syndrome.Objective and hypotheses: To present the result...

Background: Heterozygous loss-of-function HNF4A mutations are known to lead to monogenic diabetes, and in infants to macrosomia and hyperinsulinemic hypoglycemia. We are reporting a patient with a heterozygous HNF4A mutation (c.997C>T p.ARG333Cys) presenting with persistent ketotic hypoglycemia.Case report: In a 38 weeks’ gestation infant (birth weight 4.1 kg, pregnancy complicated by insulin-requiring gestational diabetes), hy...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Background: Congenital hypothyroidism (CH) is the most important cause of preventable mental retardation. Therefore, screening programme has been using for early detection of hypothyroidism in our country since 2007.Objective: To compare clinical features of newborns with and without CH who were detected in screening programme between 2009 and 2014.Method: This study enrolled 710 (344 Girls) newborn referred from CH-screening progr...

Congenital adrenal insufficiency is a potentially life-threatening condition that can present soon after birth in many different ways. The classic presentation is a salt-losing crisis due to mineralocorticoid insufficiency, often between a week and two of life, but babies with predominant glucocorticoid insufficiency can present with other features such as prolonged jaundice, hypoglycaemia and hyperpigmentation. Most children with congenital adrenal insufficiency present to em...

Background: Hypothalamic–pituitary–gonadal (HPG) axis activates soon after birth, and this ‘minipuberty’ provides a transient phase for evaluation of the function of the HPG axis in early infancy. Substantial differences in postnatal gonadotropin secretion have been reported between preterm (PT) and full-term (FT) boys and girls. Therefore, when evaluating gonadotropin levels in infants, time from birth (calendar age), maturity (postmenstrual, PM age) and s...

Background: Poor temperature regulation in Prader–Willi syndrome (PWS) suggests dysautonomia probably secondary to hypothalamic dysfunction. Autonomic nervous system (ANS) has control over orexigenic ghrelin.Objective and hypotheses: We aim to assess ANS function in PWS and its association with acyl ghrelin.Method: We recruited 16 genetically-confirmed children with PWS and 16 controls. Exclusion criteria were diabetes mellitu...

Background: Primary IGF1 deficiency (PIGFD) is a rare disease defined by low IGF1 levels, GH sufficiency and absence of secondary causes of growth failure. Whereas some members of the GH–IGF axis have been shown to be implicated in the severe syndromic forms of PIGFD due to GH insensitivity, genetic causes of less severely affected patients are mostly unknown.Objective and hypotheses: The aim of the present study was to systematically investigate fr...
