Ghaddhab Chiraz , Van Den Eeckhaute Emmanuel , Hancisse Olivier , Driessens Natacha , Versteyhe Soetkin , Miot Francoise , Dumont Jacques-Emile , Corvilain Bernard

Background: H2O2 produced in large quantities in the thyroid may play a role in the pathogenesis of thyroid nodules and cancer. In vitro, moderate amounts of H2O2 are able to cause similar DNA damage compared to irradiation and even to induce RET/PTC rearrangements.Objective and hypotheses: We compared the defence mechanisms against H2O2 and irradiation in human thyrocytes, T-cell...

Pseudopubertas Praecox in a 4 Year Old Boy with Bilateral Atypical Adrenocortical Adenomas

Brichta Corinna , Wurm Michael , Hodde Franka , van der Werf-Grohmann Natascha , Schwab Karl Otfried

Introduction: Adrenocortical tumors are very rare in children, with a prevalence of just 0.3 cases/million/year. Autonomic hormone production by adrenal cortical tumors may cause peripheral precocious puberty.Case report: A 4-year-old boy was presented by his parents because of pubertal behavior with aggressive features and a significant increase in the size of the penis. The parents also noticed a strong growth spurt and sweat odor. The boy had a good g...

Genetics of Growth Failure in Small for Gestational Age Children

Keppler Romy , van der Werft-Grohmann Natascha , Schwab Karl Otfried , Lausch Ekkehart

Background: Small for gestational age (SGA), defined as ≤−2.0 SDS birth length or weight, is a condition seen in up to 3% of all newborn. Most SGA children catch up height in postnatal life. In a significant number (~10%), however, height remains below the third centile. Recombinant GH therapy is indicated when growth failure continues to 4 years of age. The pathophysiological basis of SGA is complex: monogenic disorders and/or fetal programming by environmental fa...

Increased Required Dose of GH in Children with Inborn Panhypopituitarism

Wurm Michael , van der Werf-Grohmann Natascha , Krause Alexandra , Roemer-Pergher Cordula , Schwab Karl Otfried

Introduction: Standard dose for GH deficient children is 0.025 mg/kg per day given subcutaneously once daily. Inborn panhypopituitarism is a special subset of GH deficiency. Its management is difficult because several hormones need to be replaced. We present three patients with perinatal onset panhypopituitarism.Case reports: Case 1 is a 7-year-old boy who had hypoglycaemic seizure with reanimation due to circulatory arrest shortly after birth. Panhypopi...

Influence of hypoglycemic episodes on attention and behavioural abnormalities in diabetic children

Wurm Michael , Niebuhr Vera , Hallermann Kristiane , Krause Alexandra , van der Werf-Grohmann Natascha , Schwab Karl Otfried

Background: Type 1 diabetes may have an influence on concentration, attention and behaviour. These effects are relevant, as they may affect school performance and later career options for paediatric diabetes patients.Objective and hypotheses: This study examined attention, concentration and behavioural difficulties in diabetic children aged 5–13 years and their association with hypoglycaemic episodes and HbA1c.Method: 48 child...

Acromegaly in a 14-year-old girl with pituitary adenoma

Fingerhut Karin , Krebs Andreas , Otfried Schwab Karl , Spiekerkötter Ute , van der Werf Natascha

Introduction: Acromegaly is a rare disorder, developed by overproduction of growth hormone (GH) and insulin-growth factor 1 (IGF-1), in most cases based on a pituitary adenoma. The increased IGF-1 and GH levels lead to the growth of acres and organs as well as metabolic changes. When manifesting before epiphyseal closure, a giant growth develops.Case Report: A Ukrainian girl presented at the age of 14 years with enlargem...

Pediatric Patients with Heterozygous ALPL Mutation show a Broad Clinical Phenotype

Melanie Brichta Corinna , Wurm Michael , Krebs Andreas , Lausch Ekkehart , Van der Werf-Grohmann Natascha , Schwab Karl Otfried

Introduction: Hypophosphatasia (HPP) is a congenital disorder of the bone and mineral metabolism. It is based on mutations in the ALPL gene, which codes for tissue-unspecific alkaline phosphatase (TNSAP). Methods:The casuistic of 3 children with heterozygous ALPL mutation are presented. The patients were identified by laboratory data screening for reduced AP activity at the Children's Hospital of the University Hospital Freiburg....

Specific Hypothalamic Activation Pattern by mGlu5 Receptor Blockade in vivo During Pubertal Development in Female Mice

Inta Ioana , de Angelis Roberto , Lankisch Katja , Dormann Christof , Pfeiffer Natascha , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: Puberty is characterised by important changes of brain networks. The glutamate system plays a main role in modulating the onset of puberty as shown for NMDA receptor agonists. However, the underlying mechanisms are poorly understood. Metabotropic mGlu5 receptors (mGluR5) are tightly linked to NMDA receptors. The effect of mGluR5 blockade on neurohormonal mechanisms in puberty initiation were not studied yet.Objective and hypotheses: To invest...

Decrease of Small Dense LDL and Lipoprotein-Associated Phospholipase A2 due to Human GH Treatment in Short Children with GH Deficiency and Small for Gestational Age Status

Krebs Andreas , Kratzin Thomas , Doerfer Jurgen , Winkler Karl , Wurm Michael , van der Werf-Grohmann Natascha , Krause Alexandra , Schwab Karl Otfried

Objectives: GH deficiency (GHD) and small for gestational age (SGA) status are associated with cardiovascular risks. We therefore investigated antiatherogenic effects of GH.Methods: Subfractions of LDL and HDL, lipoprotein-associated phospholipase A2 (Lp-PLA2), and high-sensitivity C-reactive protein (hsCRP) were measured at baseline, after 8 and 52 weeks of GH treatment in 51 short children born SGA (n=33) or with GHD (n=18).<p cla...
