Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Introduction: Despite improved therapy measures since 2014 the prevalence of overweight and obesity in Swiss adolescence stabilized on 19%. Particular challenges are lack of adherence to therapy in youth who are in difficult life situations or live further from specified centres. Therefore it is essential to find simple and novel therapeutic approaches. But although the number of digital based health information systems increases steadily, the effectiveness in reaching long te...

Background: Although growth hormone (GH) and the GH releasing hormone receptor (GHRHR) are known as etiologic factors in non-syndromic isolated growth hormone deficiency (IGHD), very few mutations have been identified in this rare condition (accounting for only 6–12.5% and 0–6.7% of IGHD cases depending on studies). The functional consequences of the identified variants have rarely been assessed.Objective and hypotheses: To assess the contribut...

Thyrotoxicosis, Nephrogenic Syndrome of Inappropriate Antidiuresis, Tall Stature and Mental Retardation Caused by a Novel GNAS Gain of Function Mutation

Houang Muriel , Kottler Marie-Laure , Bensman Albert , Haymann Jean-Philippe , Richard Nicolas , Dunand Olivier , Bastepe Murate , Silve Caroline , Coudray Nathalie , Netchine Irene , Linglart Agnes

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is a very rare clinical condition. Patients suffer from hyponatremia, hypo-osmolality with inappropriately elevated urinary osmolality and undetectable AVP levels. Activating mutations of AVPR2, the vasopressin receptor type 2 (V2R), induce a prolonged signaling of the intracellular cAMP/PKA pathway and cause NSIAD in patients.Objective and hypotheses: To describe a new phenotype in a...

A Novel Homozygous Mutation of the IGF1 Receptor Gene (igf1r) in Two Siblings with Severe Short Stature, Intellectual Disability, Congenital Malformations, and Deafness

Maystadt Isabelle , Andrew Shayne F , De Schepper Jean , Wauters Nathalie , Mortier Geert , Benoit Valerie , Joset Pascal , Oneda Beatrice , Rosenfeld Ron G , Rauch Anita , Hwa Vivian

Background: Heterozygous mutations in the IGF1 receptor (IGF1R) are often associated with congenital IGF1 resistance, causing variable degrees of intrauterine growth retardation (IUGR) and postnatal short stature. To date, only one homozygous IGF1R mutation has been reported, in a child presenting with severe growth failure, mild intellectual impairment, microcephaly, dysmorphic features, and cardiac malformations.Objective: We now repo...

Introduction: HbA1C goals are rarely achieved in children with Type 1 diabetes (T1D) except at the cost of increased hypoglycaemia episodes. The Diabeloop Hybrid Closed-Loop system improves time in range and glycemic control in adults. However, the efficacy and safety of the system had not yet been evaluated in children. Our objective was to evaluate the safety and efficiency of the Diabeloop hybrid closed-loop system in prepubescent children (DBL4K).<p cl...

Evaluation of the potential benefits of biphosphonate treatment on symptomatic vertebral fractures in children treated for acute lymphoblastic leukemia

Background and Aim: Vertebral fractures (VF) in children with acute lymphoblastic leukemia (ALL) are often symptomatic and impairing life quality. Prevalence of children with VF at ALL diagnosis has been reported as 16% with peak incidence occurring during the first year after diagnosis and a 6-year cumulative incidence of 32.5%. Moreover, only 15.8% of these patients will have vertebral reshaping 24 months after ALL diagnosis. Additionally, 23% of ALL survivo...

Albert , Dattani Mehul T. ,

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background: In children, papillary thyroid cancer (PTC) is generally sporadic and may, less frequently, be part of an undiagnosed hereditary tumor predisposition syndrome (HTPS). Somatic molecular testing is useful to understand tumor etiology and behavior, predict prognosis, and possibly guide development of novel treatment strategies. RET/PTC fusions were found to be associated with an increased risk of invasive disease. The aims of our study were to analyze...
