Secondary Thyroid Cancer among Childhood Cancer Survivors: A Single Institution Experience

Muraca Monica , Bagnasco Francesca , Caruso Silvia , Morsellino Vera , Haupt Riccardo , Cabria Manlio

Background: Childhood cancer survivors (CCS) are at increased risk of developing secondary malignant neoplasms (SMN). Radiotherapy is one of the main risk factors, and secondary thyroid cancers (STC) are likely to occur among irradiated CCS.Objective and hypotheses: To evaluate frequency, characteristics, and of STC in the cohort of CCS treated and in follow-up at the Istituto Giannina Gaslini.Method: Survivors treated between 1975...

Effect of Small Size at Birth, Adult Body Size and Growth Hormone Treatment on Telomere Length

Smeets Carolina , Codd Veryan , Samani Nilesh , Hokken-Koelega Anita

Background: Small birth size followed by accelerated weight gain in early life is associated with an increased risk for age-associated diseases, such as cardiovascular disease (CVD) in later life. The underlying causes for this are largely unknown. Leukocyte telomere length (LTL) is a marker of biological age and short LTL is associated with increased CVD-risk. Subjects born small for gestational age (SGA) who remain short are treated with growth hormone (GH) to improve adult ...

Mast Cells and Steroidogenesis in the Human Fetal Adrenal

Naccache Alexandre , Louiset Estelle , Duparc Celine , Laquerriere Annie , Patrier Sophie , Renouf Sylvie , Gomez-Sanchez Celso E. , Mukai Kuniaki , Lefebvre Herve , Castanet Mireille

Background: We recently demonstrated the presence of mast cells in human fetal adrenal gland from 18–20 weeks of gestation (WG) within the subcapsular layer. In the adult adrenal, mast cells have been implicated in mineralocorticoid synthesis and secretion especially in aldosterone-producing adenomas. Because similarities exist between tumors and normal fetal development and as cell-to-cell interactions involving immune cells are implicated in organogenesis, we hypothesiz...

Establishment of Clinical and Lab Algorithms for the Identification Carriers of Mutations in CYP21A2 – A Study of 768 Children and Adolescents

Meinel Jakob , Finckh Ulrich , Schuster Andreas , Haverkamp Thomas , Richter-Unruh Annette

Background: Bi-allelic mutations of CYP21A2 encoding 21-hydroxylase are the most frequent cause of congenital adrenal hyperplasia (CAH). Non-classical CAH (NCCAH) or even just hyperandrogenism may be caused by mild or mono-allelic (single) heterozygous mutations of CYP21A2. These mutations are associated either with elevated basal or ACTH-stimulated levels of 17-hydroxyprogesterone (17OHP) in blood.Objective and hypotheses: The objective of this study wa...

Primary Pigmented Nodular Adrenocortical Disease (PPNAD) Justifying a Pediatric Case of ACTH-independent Cushing Syndrome (CS)

Capelo Liana , Vieira Stefania , Apolinario Elisa Cordeiro , Kopacek Cristiane

Background: CS is characterized by excess glucocorticoid excess, either endogenous or exogenous. In children younger than 7 years, the adrenal origin is the most common cause. From this age until adulthood predominates Cushing’s disease (central cause). We can divide CS in ACTH-dependent and independent according to laboratory findings. When ACTH-independent, etiologies are related to benign or malignant diseases of the adrenal or McCune Albright syndrome.<p class="ab...

Bartter Syndrome with Bone-Destroying Hyperparathyroidism: About Two Cases, Genetically Proved, with Long-Lasting Follow-Up

Novo Robert , Cartigny Maryse , Lefevre Christine , Weill Jacques

Background: Bartter syndrome represents a rare severe condition, autosomal recessive, corresponding to several genes, characterized by an illness of the renal ascending branch of the handle of Henle. Only 15 cases of BSHPT have been communicated, either in publications or orally, but none presented such severe bone manifestation as ours.Objective and hypotheses: To present bone features of two patients suffering from severe BHSPT, so as the therapeutic a...

Recombinant Human Insulin-Like Growth Factor 1 (rh IGF1) Treatment of a Case of Leprechaunism: A Two and a Half Year Follow-Up

Valle Aline , Lefevre Christine , Weill Jacques , Cartigny Maryse

Background: Leprechaunism, due to a mutation of both alleles of insulin receptor gene, is a most severe and precociously life-threatening condition, difficult to treat.Objective and hypotheses: In leprechaunism rhIGF1 may replace insulin through I the insulin-like metabolic properties of its own receptor.Method: rh IGF1 was continuously subcutaneously administered through a.pump from the age of four months and adjusted according to...

Diagnosis of Non-Autoimmune Paediatric Diabetes by Targeted Next Generation Sequencing (NGS): Findings in Two Families with Rare Mono- and Digenic forms of Diabetes

Poidvin Amelie , Donath Xavier , Saint-Martin Cecile , Loison Sylvie , Carel Jean-Claude , Bellanne-Chantelot Christine , Tubiana-Rufi Nadia

Background: Nearly 10% of paediatric onset diabetes are auto-antibodies negative. Among them monogenic diabetes are frequently under-diagnosed. The major increase in the prevalence of childhood obesity is misleading with a risk of confusion between type 2 diabetes (T2D) and monogenic causes of diabetes.Objective and hypotheses: To report on two informative families with negative auto-antibodies childhood-onset diabetes cases.Method...

Extrahepatic Biliary Atresia in Combination with Toxic Cholestasis Due to Glibenclamide in a Case of Neonatal Diabetes

Kapellen Thomas , Flemming Gunter , Bartelt Heike , Wachowiak Robin , Kiess Wieland

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...

Microalbuminuria in Type 1 Diabetes – Audit of Management of Children and Adolescents in a Single Diabetes Centre

Nambisan Aparna Kesavath Raman , Spowart Karen , Alatzoglou Kyriaki Sandy , Bridges Nicola , Alexander Saji

Background: There are international guidelines on screening for Microalbuminuria (MA) in children with Type1 Diabetes Mellitus (T1DM). But the National Paediatric Diabetic Audit, UK suggests that screening is missed in over 50% of cases. Further, there is little data on the management and natural course of MA in children by frontline units.Objective and hypotheses: To describe the prevalence, management and natural course of MA in children and adolescent...
