Kinetics of FT4 serum concentrations in newborns and infants with congenital hypothyroidism during follow-up differ in the three severity groups

Steffens Britta , Gächter Pascal , Koch Gilbert , l'Allemand Dagmar , Janner Marco , Konrad Daniel , Welzel Tatjana , Pfister Marc , Szinnai Gabor

Background: The goal of congenital hypothyroidism (CH) treatment is rapid normalization and maintenance of TSH and FT4 in the reference range. Recommended starting dose of levothyroxine (LT4) ranges from 10-15 mg/kg/d. Hyperthyroxinemia can be accepted in the context of normal TSH and LT4 should only be reduced in case of symptoms or repeatedly increased FT4. The aim of this study was to quantify duration and maximum peak of FT4 levels outside the reference range for each CH s...

Longitudinal Auxological Recovery and Reduced Neurodevelopmental Problems in Hyperinsulinaemic Hypoglycaemia

Worth Chris , Hashmi Laila Al , Yau Daphne , Salomon-Estebanez Maria , Perez-Ruiz Diego , Hall Caroline , O’Shea Elaine , Pimlott Helen , Foster Peter , Flanagan Sarah , Cosgrove Karen , Dunne Mark , Banerjee Indraneel ,

Background: Hypoglycaemia due to congenital hyperinsulinism (CHI) is the commonest cause of severe, recurrent hypoglycaemia in childhood. Previous follow up studies have focused on neurodevelopmental status which is noted to be delayed in as many as 48% of cases. There has been less emphasis on other long-term outcomes in patients with CHI. Given the requirement for high volume carbohydrate in most patients, there are concerns regarding the adverse effects on ...

Novel SOX2 Mutation: Identification of New Molecular Mechanisms of SOX2 Action and Interactions

Alatzoglou Kyriaki S. , Andoniadou Cynthia L. , Kelberman Daniel , Kim Hyoong-Goo , Botse-Baidoo Edward , Pedersen-White Jennifer , Layman Lawrence , Martinez-Barbera Juan Pedro , Dattani Mehul T.

Background: SOX2 is an early developmental transcription factor implicated in pituitary development; heterozygous SOX2 mutations have been reported in patients with a severe ocular phenotype and hypogonadotrophic hypogonadism (HH) with/without associated abnormalities. SOX2 physically interacts with β-catenin, a member of the Wnt-signalling pathway, via its carboxyl-terminus and it represses in vitroβ-catenin mediated activation.<p class="abstex...

Dynamic Changes in Growth and IGF-I During the First Year of Life; A Longitudinal Study of 233 healthy Danish Infants

Upners Emmie N. , Ljubicic Marie L , Busch Alexander S , Fischer Margit B , Almstrup Kristian , Petersen Jorgen H , Jensen Rikke B , Hagen Casper P , Juul Anders ,

Background: Growth during infancy is a continuation of the rapid fetal growth and its regulation is complex and multifactorial. It is well-established that insulin-like growth factor-I (IGF-I) and its regulators (e.g. IGF binding proteins (IGFBP-3) and pregnancy-associated plasma protein-A2 (PAPP-A2)) are important for prenatal and postnatal growth; however, their significance for growth during infancy is not fully explored.Aims: The aim...

Life Long Management of Childhood Craniopharyngioma

Müller Hermann L.

Craniopharyngiomas (CP) are rare, partly cystic and calcified embryonic malformations of the sellar/parasellar region with low histological grade (WHO Io). A bimodal age distribution has been shown, with peak incidence rates in childhood-onset at 5–14 yr and adult-onset CP at 50–74 yr. Clinical manifestations are related to hypothalamic/pituitary deficiencies, visual impairment, and increased intracranial pressure. Recent insight in molecular pathogenesis of CP opens...

Ovarian steroid cell tumors (OSCT) are rare sex cord stromal tumors of the ovary and comprise <0.1% of all ovarian tumors. We herein report a case of an OSCT in a 9 year old girl patient who presented with central puberty preocious unresponsive to gonadotrophine relasing hormon analog (GnRH) therapy. A 9 year old girl presented with breast development noticed 4 months ago and menarche 3 months ago. Her height was 141,5 cm (+1,3 SDS), body weight was 35.4 kg (+0.9 SDS) and...

Thyroid Function and Autoimmunity and Their Relation to Weight Status in Healthy Children and Adolescents

Garcia-Garcia Emilio , Galera-Martinez Rafael , Garcia-Escobar Iciar , Oliva-Perez Patricia , Gomez-Llorente Jose L. , Momblan Jeronimo , Vazquez-Lopez Maria A. , Perales Antonio Bonillo

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Introduction: Neonatal diabetes mellitus (NDM) is a rare monogenic disease associated with genetic defects in pancreatic beta cell number and/or function. It can be divided into two forms: transient neonatal diabetes mellitus (TNDM) and permanent neonatal diabetes mellitus (PNDM). TNDM is usually diagnosed within the first month after birth and usually regresses before the age of one year, but may reappear during adolescence. In contrast, PNDM is a lifelong di...
