The Experience of GAIA (Abuse Childhood and Adolescence Group) – AOU Meyer

Losi Stefania , Anzilotti Giulia , Scalini Perla , De Martino Maurizio , Stagi Stefano

Background: GAIA is a health service of Meyer Children Hospital composed of a multidisciplinary team specialized in the management of children victims of child abuse. Sexual abuse occurs when a child is engaged in sexual activities that cannot comprehend, for which the child is developmentally unprepared and cannot give consent, and/or that violate the law or social taboos of society. The sexual activities may include all forms of oral-genital, genital, or anal contact by or t...

Spectrum of the Genetic Defects in Hypophosphatemic Rickets in A Group of Turkish Children

Acar Sezer , Al-Rijjal Roua A. , Demir Korcan , Kattan Walaa E. , Catli Gonul , BinEssa Huda , Abaci Ayhan , Dundar Bumin , Zou Minjing , Kavukcu Salih , Meyer Brian , Bober Ece , Shi Yufei

Background: There exists limited data regarding genetic etiology of hypophosphatemic rickets in Turkey.Objective and hypotheses: To investigate the type of genetic defect in 16 index children and their families (12 unrelated, 1 related).Method: Following clinical and laboratory assessment, PHEX analysis was made initially unless a mutation in another gene was suspected. If negative, FGF23, SLC34A3, SL...

Novel CYP27B1 Gene Mutations in Children with Vitamin D-Dependent Rickets Type 1A

Demir Korcan , Kattan Walaa E , Zou Minjing , Durmaz Erdem , BinEssa Huda , Nalbantoglu Ozlem , Al-Rijjal Roua A , Meyer Brian , Ozkan Behzat , Shi Yufei

Background: The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause a rare autosomal recessive disorder, vitamin D-dependent rickets type 1A.Objective and hypotheses: To investigate CYP27B1 mutations in children when rickets was associated with normal or high vitamin D levels and low or inappropriately normal calcitriol levels.Method: All coding exons and intron-exon boundari...

Dynamic Control of Tissue Glucocorticoids – Lessons for Optimising Replacement Therapy

Walker Brian

Although Endocrinologists have focused for decades on circulating concentrations of cortisol, arguably the important concentrations are those within tissues which are available at corticosteroid receptors. Tissue concentrations are influenced by plasma proteins binding cortisol, by physicochemical characteristics of the steroid, by active transport across cell membranes, and by steroid metabolism within target tissues. Many of these factors vary between individuals, and within...

Maternal Hepatic HKDC1 Expression Impacts Offspring Glucose Metabolism

Jo Inha , Khan Md. , Layden Brian

Gestational Diabetes (GDM) increases risk of developing type 2 diabetes in the mother and child later in life however, despite the increasing prevalence of GDM, its molecular mechanism remains unknown. A recent Genome-Wide Association Study (GWAS) identified a unique genetic association of the novel 5th hexokinase, hexokinase domain component-1 (HKDC1) to gestational glucose tolerance at 28 weeks of gestation linking it to GDM. We have previously shown that liver-specific over...

Insight into the Human Ovarian Sex Development Networks

Bouazzi Leila , Franco Mariangela , Eid Wassim , Meyer-Boni Monika , Sproll Patrick , Maret Alexander , Lauber-Biason Anna

Background: Ovarian sex differentiation network involves a panoply of interacting factors. Yet, no single sex-determining factor has been identified to be an equivalent of SRY or SOX9 in the testis. Recently, data suggested CBX2 as a pioneer regulator promoting testis development. In addition to its implication in ovary pathway differentiation which remains unclear.Objective and hypotheses: To deepen our understanding of the regulatory network that under...

The Role of Adipocytes in Childhood Precursor Bcell Lymphoblastic Leukemia

Brenner Elena Dorothea , Zinngrebe Julia , Dahlhaus Meike , Meyer Lueder-Hinrich , Wabitsch Martin , Debatin Klaus-Michael , Fischer-Posovszky Pamela

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in childhood. Over the past decades, survival rates increased, but relapse is still associated with a poor prognosis, especially if the bone marrow (BM) is affected. Marrow adipose tissue (MAT) constitutes a major part of the BM niche, but its impact on normal hematopoiesis versus leukemia initiation, progression and relapse has only recently gained attention. MAT is very sensitive to changes in the patient’s...

Hypoglycemia as a result of skewed thiopurine metabolism in two pediatric patients

Seong Clara , Giordano Lisa , Seyboth Brian , Minutti Carla

Introduction: 6 Mercaptopurine (6MP) is a cornerstone of maintenance therapy in pediatric acute lymphoblastic leukemia (ALL). Fasting hypoglycemia is a rare side effect of 6MP therapy that has been observed in children being treated for ALL. We present two pediatric patients who developed symptomatic, fasting hypoglycemia during maintenance therapy.Case Description: A 7-year-old male with standard risk B ALL receiving ma...

WES Analysis of a Cohort of 94 Patients Presenting with 46,XY and 46,XX DSD

Sproll Patrick , Stevenson Brian , Nef Serge , Biason-Lauber Anna

Background: Disorders/Differences of Sex Development (DSD) is diagnosed in approximately one out of 4'500 newborns. Children born with DSD present with a very diverse phenotype and they and their families face considerable challenges, potentially including surgical intervention and gender assignment, as well as associated complications such as infertility and predisposition to gonadal tumors. Due to the lack of knowledge concerning the complete gene and pr...

A Monomeric Peptide Triagonist for the Treatment of Obesity and Diabetes

Clemmensen Christoffer , Finan Brian , Muller Timo , DiMarchi Richard , Tschop Matthias

Encouraged by unimolecular dual incretin co-agonists (GLP1/GIP) to enhance glycemic efficacy (Finan et al. 2013, Sci Transl Med) and GLP1/glucagon co-agonists to enhance weight loss efficacy (Day et al. 2009, Nat Chem Biol) and to restore diet-induced leptin sensitivity (Clemmensen et al. 2014, Diabetes), we recently developed the first tri-agonist (GLP1/GIP/glucagon) for the treatment of metabolic disorders (Finan et al. 2014, Nat Med). Importantly, this concerted triple agon...
