Background and Aims: Type 1 diabetes mellitus (T1DM) belongs to the most common chronic diseases affecting children and adolescents. Technological advances have improved metabolic control over the past decades, thereby decreasing the risk of long-term complications. However, only a minority of patients meets the treatment goals of maintaining a glycated hemoglobin (HbA1c) level below 7.5% (58 mmol/mol). Webdia is an application for mobile devices developed by the fath...

Frontal Behavior Dysfunctions Revealing a Dramatic Progression of Complex Cranial Base Abnormalities in a Severe Osteogenesis Imperfecta

Porquet-Bordes Valerie , Grandgeorge Naia , Moulin Pierre , Cheuret Emmanuel , Boetto Sergio , Sales De Gauzy Jerome , Gennero Isabelle , Tauber Maite , Edouard Thomas , Salles Jean Pierre

Background: In our bone unit, we were following since their younger age, two brothers with a severe osteogenesis imperfecta. We had no genetic confirmation but the severity of the disease combined with unaffected consanguine parents argues for a recessive autosomal transmission. Both present with highly severe form of osteogenesis imperfecta: repeated vertebral and peripheral fractures, long bone deformations, centromedullary nails on the lower limbs, major motor handicap and ...

Ybarra Marina , Daniels Prince Kevin , Van Hulst Andraea , Barnett Tracie A , Mathieu Marie-Eve , Drouin Olivier , Kakinami Lisa , Bigras Jean-Luc , Henderson Melanie

Introduction: Childhood obesity is an international pandemic which affects 13% of Canadian youth, and is the leading cause of cardiovascular disease (CVD) in children. While the optimal approach to treat pediatric obesity remains elusive, comprehensive and intensive behavioral interventions which leverage the child’s living environment in order to promote improvements in healthy lifestyles appear promising. The CIRCUIT program (Centre Pédiatrique d’Intervent...

Determinants of Attrition from a Healthy Lifestyle Intervention: Experience from the CIRCUIT Program

Daniels Prince Kevin , Ybarra Marina , Van Hulst Andrea , Barnett Tracie A , Mathieu Marie-Eve , Drouin Olivier , Kakinami Lisa , Bigras Jean-Luc , Henderson Melanie

Introduction: Pediatric obesity is a global public health problem that is associated with severe cardiometabolic consequences. Weight management interventions focusing on lifestyles have shown some promising results, but attrition rates are often high and reasons for dropout are poorly understood.Objectives: We aimed toestimate the prevalence, and identify the determinants of attrition among pediatric participants in the first year of a 2-year lifestyle ...

Does X-Chromosome Gene Dosage Determine Growth and Phenotypic Features in Turner Syndrome with 45,X/46,XX Mosaicism on Standard Karyotyping? A Cross-Sectional Analysis of the French National Rare Disease Network Database

Fiot Elodie , Zenaty Delphine , Pick Paul , Boizeau Patricia , Haignere Jeremy , Dos Santos Sophie , Christin-Maitre Sophie , Carel Jean-Claude , Leger Juliane , Turner Syndrome Study Group French

Background: Turner Syndrome (TS) with a 45,X phenotype is generally more severe than TS with mosaicism, but the potential role of the degree of mosaicism in modulating TS phenotype has never been investigated. We assessed the impact of various degrees of 45,X/ 46,XX mosaicism on phenotypic features in a cohort of TS patients.Method: We analysed a cohort of TS with 45,X/ 46,XX mosaicism (percentage mosaicism from peripheral blood lymphocytes, known in <em...

Early Determinants of Thyroid Function Outcome in Children with Congenital Hypothyroidism and a Normally Located Thyroid Gland: A Regional Cohort Study

Saba Carole , Guilmin-Crepon Sophie , Zenaty Delphine , Martinerie Laetitia , Paulsen Anne , Simon Dominique , Santos Sophie Dos , Haignere Jeremy , Mohamed Damir , Jean-Claude Carel , Juliane Leger

Background: An increase in the incidence of congenital hypothyroidism (CH) with a normally located gland has been reported worldwide. Affected individuals display transient or permanent CH during follow-up in childhood. We aimed to determine the prevalence of transient CH and to assess the possibility of distinguishing between transient and permanent CH in early infancy.Methods: This observational cohort study included all patients identified by systemat...

Neonatal Monitoring of Newborns Born from Mothers with Graves’ Disease: Results of a Retrospective Monocentric Study

Dumaine Cecile , Crepon Sophie Guilmin , Pages Justine , Chevenne Didier , Rosenblatt Jonathan , Storey Caroline , Martinerie Laetitia , Carel Jean-Claude , Zenaty Delphine , Leger Juliane , Simon Dominique

Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Persistent Beneficial Metabolic Effect after Five Years in a Cohort of 28 Subjects with Neonatal Diabetes owing to Potassium Channel Mutation and Transferred from Insulin to Sulfonylureas

Hoarau Marie , Fauret Anne-Laure , Busiah Kanetee , Godot Cecile , Colas Sandra , Treluyer Jean-Marc , Scharfmann Raphael , Cave Helene , Polak Michel , Beltrand Jacques

Background: Sulfonylureas (SU) have proven to be effective in patients with monogenic diabetes owing to potassium channel mutation. They allow the discontinuation of insulin and a good metabolic control. Long-term data arguing for a persistent beneficial effect of SU are missing.Objective and hypotheses: SU provide a good metabolic control maintained over time in patients with neonatal diabetes.Method: From a French cohort of 34 pa...

Clinical Management of the Mitchell-Riley Syndrome Due to RFX6 Gene Mutations: Aggressive Support Results in Improved Outcome

Poidvin Amelie , Chandra Vikash , Fauret-Amsellem Anne-Laure , Cave Helene , Beltrand Jacques , Tubiana-Rufi Nadia , Carel Jean-Claude , Polak Michel , Scharfmann Raphael

Background: Homozygous mutations in the transcription factor RFX6 are the cause of the Mitchell-Riley syndrome associating neonatal diabetes, pancreatic hypoplasia, gallbladder agenesis, duodenal atresia, and severe chronic diarrhea. Nine cases have been reported so far and the condition has a poor prognosis with five of nine patients died before the age of 6 months.Objective and hypotheses: To report on the clinical management and outcome of tw...

Background: Monogenic diabetes is a heterogeneous group of metabolic disorders resulting from defects in single genes. Over 90% of the subjects remain undiagnosed, mainly because of lack of access to genetic testing.Objective and hypotheses: The aim of our study was to do a comprehensive genetic analysis of the whole pediatric and young adult autoimmune antibody negative diabetes population of Lithuania.Method: 860 children (age 0&...
