Fuentes-Bolanos Noemi , Dolores Martin Salvago Maria , Martinez Moya Gabriela , del Toro Codes Marta , de la Cruz Moreno Jesus

Background: Mammary duct ectasia is a bening breast condition which affects primarily middle-aged to elderly women. However, it can occurs wherever there is breast ductal epithelium.Case presentation: A 9-years-old boy was referred to the regional paediatric endocrine clinic from the General Practicioner due to gynaecomastia. Pubic hair development started at the age of 8. Personal and family history were unremarkable except for a history of coping with ...

Iodide Transport Defect: Identification of a Novel Mutation in the Carboxy-terminus of the Sodium/iodide Symporter in a Pediatric Patient with Congenital Hypothyroidism

Nicola Juan Pablo , Martin Mariano , Signorino Malvina , Testa Graciela , Sobrero Gabriela , Munoz Liliana , Masini-Repiso Ana Maria , Miras Mirta

Iodide (I−) transport defect (ITD) is an autosomal recessive disorder caused by the inability of the thyroid follicular cell to actively accumulate iodide. Active I− accumulation is mediated by the Na+/I− symporter (NIS), an integral plasma membrane glycoprotein located on the basolateral surface of thyrocytes. The diagnostic criteria for ITD include a variable degree of hypothyroidism and goiter, low to absent thyr...

Characterization of IGFI Receptor Expression and Localization in Paediatric Gliomas Upon Diagnosis According to WHO 2007 Grading

Clement Florencia , Venara Marcela , Maglio Silvana , Martin Ayelen , Matho Cecilia , Petre Cesar , Lombardi Mercedes Garcia , Bergada Ignacio , Pennisi Patricia

Background: Gliomas are the most common subgroup of CNS tumours in children. Histologic grading is a means of predicting the biological behavior of these tumours and survival is strongly correlated with tumour gradation. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, nuclear translocation of the type 1 IGF1R has been demonstrated in tumour tissues. Although the IGF1R expression has been described in C...

Identification of Death Ligand TNF-Related Apoptosis-Inducing Ligand as a Potent Mitogen in Human Preadipocytes

Funcke Jan-Bernd , Zoller Verena , El Hay Muad Abd , Debatin Klaus-Michael , Wabitsch Martin , Fischer-Posovszky Pamela

Background: Adipose tissue is an important endocrine organ. Its secretion profile is robustly changed in the context of obesity fueling the development of comorbidities such as insulin resistance, diabetes mellitus type 2, and atherosclerosis. We have recently shown that the adipose tissue expression of the death ligand TNF-Related Apoptosis-Inducing Ligand TRAIL and its receptors is upregulated in obesity.Objective and Hypotheses: In this project, we in...

Children and Adolescents with Type 1 Diabetes have Higher Plasma Visfatin Levels than Healthy Controls

Hontzsch Julia , Jasser-Nitsche Hildegard , Grillitsch Marlene , Suppan Elisabeth , Weinhandl Gudrun , Riedl Regina , Barowitsch Christine , Borkenstein Martin , Frohlich-Reiterer Elke

Background: The aim of this study was to examine plasma visfatin levels in pediatric patients with type 1 diabetes (T1D). Visfatin, a novel adipokine, is predominantly secreted by visceral adipose tissue and seems to have insulin-mimetic effects. It has not been studied in children and adolescents with type 1 diabetes (T1D) yet.Objectives: We studied 124 subjects; 62 patients with T1D: 31 girls, mean age 13.7±3.7 years; mean duration of diabetes 5.9...

TNF-Related Apoptosis-Inducing Ligand Induces a Pro-Inflammatory Secretion Profile in Human Adipocytes

Zoller Verena , El Hay Muad Abd , Funcke Jan-Bernd , Debatin Klaus-Michael , Wabitsch Martin , Fischer-Posovszky Pamela

Background: Obesity is tightly associated with adipose tissue inflammation. Tumor necrosis factor-alpha (TNFα) has been identified as a key player in this inflammatory process and has been linked to the development of obesity-associated insulin resistance. Our group studies the involvement of TNF superfamily members in obesity-induced alterations in adipose tissue.Objective and hypotheses: Here, we aimed to identify the effects of the TNF superfamil...

Being Overweight During the Peripubertal Period Modifies the Leptin Induced Changes in Hypothalamic Neuropeptides Involved in Metabolism but not those Involved in Pubertal Onset

Castro-Gonzalez David , Fuente-Martin Esther , Sanchez-Garrido Miguel A , Argente-Arizon Pilar , Tena-Sempere Manuel , Chowen Julie A , Argente Jesus

Background: Leptin is suggested to be a permissive factor in the onset of puberty by signaling at the level of the hypothalamus to indicate adequate energy stores. Overweight female rats due to increased neonatal nutrition have been shown to develop puberty before normal weight rats.Objective and hypothesis: We hypothesized that this permissive effect may be due not only to increased leptin levels, but also to increased hypothalamic sensitivity to this h...

Prevalence of Atopic Diseases in Diabetic Children and Adolescents

Jasser-Nitsche Hildegard , Varga Eva-Maria , Frohlich-Reiterer Elke , Hontzsch Julia , Pieringer Lisa , Avian Alexander , Borkenstein Martin

Background: In the last decade, an increase in the incidence of type 1 diabetes mellitus (T1D) has been observed worldwide, as well as an increase in the incidence of allergies in childhood. Both diseases are characterized by an imbalance between Th1- and Th2 cells. Autoimmune disorders are considered to be associated with a Th1 immune response while allergic diseases with a Th2 response. However, studies conducted to find a correlation between T1D and atopic diseases are hete...

Screening in Children with Succinate Dehydrogenase B (SDHB) Mutations: a Single Centre’s Family Clinic Experience

Shapiro Lucy , Srirangalingam Umasuthan , McAndrew Lorraine , Martin Lee , Tufton Nicola , Kumar Ajith , Drake William , Akker Scott , Storr Helen

Background: Germline mutations in SDHB gene are associated with the familial paraganglioma (PGL) syndrome that carries the highest malignant potential. Although penetrance is lower than initially described, lack of effective treatments for metastatic PGLs makes screening essential for early tumour detection, surgical removal and improved outcome. However, no consensus exists in relation to timing and mode of screening.Objective: To assess publis...

Somatic Paternal UPD on Chromosome 11p15 in Focal Form of Congenital Hyperinsulinism (CHI) Causes Monoallelic Expression of Mutant ABCC8 and KCNJ11

Dallmann Ina , Vogelgesang Silke , Barthlen Winfried , Varol Emine , Mohnike Wolfgang , Empting Susann , Mohnike Klaus , Zenker Martin , Wieland Ilse

Background: Congenital hyperinsulinism (CHI) is a disorder characterised by dysregulation of insulin secretion that leads to severe hypoglycaemia in neonates and infants. The focal form of CHI is caused by an autosomal recessive mutation in the genes ABCC8 or KCNJ11 inherited from the father and a second somatic event in the affected islet of Langerhans.Objective: We report molecular genetic examination of focal pancreatic lesions of patients receiving t...
