Introduction: People’s weight-related behaviors may be influenced by their personal social network (SN), notably via family and friends’ behavioral modelling and motivational social support (SS).Objective: We examined the cross-sectional relation between social network-based social support (SS) and weight-related outcomes among adolescents ina pilot study within the QUALITY cohort, a longitudinal study investigating the natural...

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...

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 ...

Background: Patients with hyperinsulinism (HI) and anterior hypopituitarism often present in the new-born period (NBP). However up to 30% patients with HI and an unknown number with hypo-pit will present in the first year of life. Despite advances in care the long-term neurological outcome for patients with HI is poor in 20-40% cases.Aim: To retrospectively evaluate the care given during the NBP in a series of patients diagnosed with late presenting pote...

Introduction: Focal disease of the pancreas causing hyperinsulinism (FHI) has 2 essential characteristics 1) the inheritance of a paternally derived mutation in ABCC8 or KCNJ11 in conjunction with loss of a region of the maternal chromosome 11p13.1 and 2) the ability to be cured by resection of the focal lesion while sparing the majority of the pancreas. At the time of surgery the surgeon resects the focal lesion until clear margins are avail...

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...

Background: DICER1 is a member of the Ribonuclease III family that plays a crucial role in the biogenesis and the maturation of microRNAs. Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations: in addition to first described pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumours, individuals may also develop benign (multinodular goiter MNG, cystic nephroma\.) or malignant tumours as differen...

Background: Monitoring treatment of children with classic congenital adrenal hyperplasia (CAH) is difficult and biochemical targets are not well defined.Objective and hypotheses: To analyse the urinary steroid metabolome of children with classic 21-hydroxylase deficiency (21-OHD) during treatment with hydrocortisone and fludrocortisone.Method: We retrospectively analysed 553 daily urinary steroid hormone metabolite profiles determi...

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Background: The incidence of perinatal stress hyperinsulinism (PSHI) requiring diazoxide treatment is estimated to be 1:12,000 (Hoe et al., 2006). Diazoxide is used to treat PSHI, but it has been shown to have adverse effects including pulmonary hypertension. Gray et al, reported that of 1.25 million infants admitted to NICUs for hypoglycemia over a period of 18 years, only 1066 received diazoxide suggesting 1:1172 babies had HI however 92% o...
