Background: Acquired Von Willebrand's syndrome (aVWS) associated with hypothyroidism is rare in children and more often diagnosed during the peripubertal period in the context of Hashimoto's thyroiditis.Case presentation: A 5-year-old girl was referred to the paediatric haematology unit for rectal bleeding, anaemia, and prolonged activated partial thromboplastin time. Her developmental and learning skills were no...

Criteria for First-Year Growth Response to Growth Hormone Treatment in Prepubertal Children with Growth Hormone Deficiency: Do they Predict Final Height Outcome?

Straetemans Saartje , De Schepper Jean , Thomas Muriel , Tenoutasse Sylvie , Beauloye Véronique , Rooman Raoul , BESPEED the members of

Background/Aim: Several criteria for the first year growth response (FYGR) to growth hormone (GH) treatment have been proposed. We explored which FYGR criteria predict best the final height outcome after GH treatment in prepubertal children with GH deficiency (GHD).Methods: Height data of 129 GHD children (83 boys) treated with GH for at least 4 consecutive years with at least 1 year before pubertal onset, were retrieved...

Identification of the MAPK/ERK Pathway as a Novel Therapeutic Target in Adamantinomatous Craniopharyngioma

Guiho Romain , Apps John R , Hong Ying , Hargrave Darren , Brogan Paul , Jacques Thomas S , Martinez-Barbera Juan Pedro

Adamantinomatous craniopharyngiomas (ACPs) are clinically challenging tumours, the majority of which have activating mutations in CTNNB1. They are histologically complex, showing solid tumor component comprised of different morphological cell types (e.g. β-catenin accumulating cluster cells and palisading epithelium), surrounded by a florid glial reaction with immune cells, but also a cystic component. ACP cysts often exert substantial mass effect on critical str...

Clinical and Biochemical Phenotype of Aldosterone Synthase Deficiency

Fortsch Katharina , Doing Carsten , Wudy Stefan A , Hartmann Michaela F , Martin Holterhus Paul , Mayatepek Ertan , Reinauer Christina , Meissner Thomas , Kummer Sebastian

Background: Biallelic mutations of the CYP11B2 aldosterone synthase gene cause deficiency of aldosterone synthesis. Patients exhibit isolated deficiency of aldosterone biosynthesis, increased plasma renin activity, increased steroid precursors desoxycorticosterone, corticosterone, as well as 18-hydroxy-desoxycorticosterone, and show salt wasting and poor growth. The aldosterone synthase enzyme has 18-hydroxylase (corticosterone methyloxidase type I, CMO I) and 18-oxidase (CMO ...

Neonatal Hypocalcemia Revealing a Malignant Osteopetrosis

Porquet-Bordes Valerie , Gohier Heloise , Lescure Sandra , Pasquet Marlene , Baunin Christiane , Gennero Isabelle , Tauber Maite , Salles Jean Pierre , Edouard Thomas

Background: A one-month girl was referred to our unit for hypocalcemia. She was the first child of healthy non-consanguineous parents. Her family history was unremarkable except a miscarriage in the mother and oligoasthenospermia in the father that justified a medically assisted reproduction. She was born eutrophic at term after a pregnancy marked by a moderate gestational diabetes. On day 3, a routine neonatal screening revealed a severe asymptomatic hypocalcemia (total calci...

Serum NAMPT Levels are not Associated with Parameters of Liver Function in Children and Adolescents

Penke Melanie , Schuster Susanne , Dietz Yvonne , Garten Antje , Grafe Nico , Karlas Thomas , Wiegand Johannes , Korner Antje , Kiess Wieland

Background/Aim: Serum NAMPT (nicotinamide phosphoribosyltransferase) levels are altered in adult patients with non-alcoholic fatty liver disease (NAFLD). However, less is known about NAMPT serum levels children and adolescents and their association with parameters of liver function.Methods: Blood and anthropometric data of 416 children and adolescents who participated in the LIFE Child Study Leipzig were collected. Serum NAMPT (Adipogen) and cytokeratin-...

Pituitary Adenomas in Children and Adolescents: A Retrospective Single-Centre Analysis

Breil Thomas , Lorz Catherine , Choukair Daniela , Mittnacht Janna , Inta Ioana , Klose Daniela , Jesser Jessica , Schulze Egbert , Bettendorf Markus

Background: Paediatric pituitary adenomas are rare and mostly benign disorders which may secrete pituitary hormones. Prolactinomas account for half of all pituitary adenomas (PROLA), followed by non-secreting adenomas (20–40%; incidentalomas), adrenocorticotropic-hormone secreting adenomas (10–30%; ACTHA) and growth-hormone-secreting adenomas (5–15%; GHA).Methods: In this single-centre retrospective analysis clinical, biochemical and radio...

Loss of Functional Osteoprotegerin: More than a Skeletal Problem

Grasemann Corinna , Unger Nicole , Hovel Matthias , Arweiler-Harbeck Diana , Lausch Ekkehart , Meissner Thomas , Hauffa Berthold P. , Shaw Nick

Background: Juvenile Pagets disease (JPD), an ultra-rare, debilitating bone disease stemming from unopposed RANKL action due to loss of functional osteoprotegerin (OPG) is caused by recessive mutations in TNFRSF11B. A genotype-phenotype correlation spanning from mild to very severe forms is described.Objective and hypotheses: To describe the complexity of the human phenotype of OPG deficiency in more detail and to investigate heterozygous mutation carrie...

DKA During Diabetes Therapy: Multinational Comparison with 59 191 Pediatric Patients from England, Wales, The United States, Austria and Germany

Warner Justin , Hermann Julia , Kapellen Thomas , Hofer Sabine , Dubose Stephanie , Schatz Des , Beck Roy , Schweiger Claudia , Maahs David , Holl Reinhard

Background: DKA in children and adolescents with established type 1 diabetes (T1D) is a major problem with considerable cost to patients, families and health care systems. Many consider it as a quality of care indicator and a failure of relationship between the care provider and the family/patient. Considerable variability in rates are recognized. We analyzed multicenter registry and audit data from five countries with similarly advanced, yet differing, health care systems.</p...

Treatment Options in a 14-Year-Old Boy with an Atypic Cabergolin-Resistant Macroprolactinoma with Somatostatin Receptor 2 Expression and an Increased Proliferation Rate

Huebner Angela , Reschke Felix , Hahn Gabriele , Pinzer Thomas , Meinhardt Matthias , Pyper Anke , Cannavo Salvatore , Stalla Gunter , Hofbauer Lorenz C.

Background: Macroprolactinomas in children below 10 years of age are rare. Usually prolactinomas respond well to dopamine agonists so that neurosurgical resection is rarely necessary. For non-responders to dopamine agonist therapy other extended treatment options have to be considered.Clinical case: We report a 14-year-old boy who presented at the age of 11 years with headaches for 5 years and progressive bilateral vision problems. The diagnosis of a mac...
