Objectives: Impaired fasting glucose (IFG) is a risk factor for the development of type 2 diabetes in adults. In obese children and adolescents, IFG and impaired glucose tolerance constitute distinct prediabetic stages, which do not necessarily coexist. Pathophysiological mechanisms leading to IFG in children have not been fully elucidated. Available data from cohorts of obese adolescents living in the US suggest a concurrent worsening of insulin sensitivity a...

Introduction: Metabolic control (MC) of patients with type 1 diabetes (DM1) is linked with complications in short and long term follow up. Adolescence is a critical period in the treatment of DM1, making it difficult to achieve good MC. Few studies, all conducted in the United States, have shown an association between mother´s depressive symptoms with poorer MC of their adolescent.Objective: To evaluate the associat...

Background: One of the main concerns in patients with growth disorders is to achieve optimal adherence to growth hormone (GH) treatment. For this it is important to identify patients with low adherence to treatment and to evaluate actions to improve it.The Merck Patient Support Program (PSP) carried out educational actions aimed at patients with low adherence and their parents, to raise their awareness of the importance of good adherence...

Objectives: Compared to the US, prevalence rates of T2DM in obese children are significantly lower in European countries. Data from cohorts of obese children living in the US suggest a concurrent worsening of insulin sensitivity and ß-cell function over the spectrum of glucose tolerance. If these results can be applied to European populations is currently unknown.Methods: A combination of our novel method for mathematical modelling ...

Background: In non-Caucasian youth residing in low-income settings, risk of mortality and rates of diabetes complications are substantially higher and clinical phenotypes may be distinct.Objectives: To assess the clinical presentation, glycemic control, and chronic complications of diabetes in Haitian youth residing in Haiti.Methods: Retrospective review between 01/2013–03/2018 of youth 0-25 years with diabetes followed at a c...

Deletions at 16p11.2 have been reported to be associated with obesity, intellectual disability and various malformations. There are variations in phenotypes associated with deletions of different sizes in this region. Some deletions encompass the SH2B1 gene encoding an adaptor protein involved in leptin and insulin signalling which is believed to be causal for the early-onset obesity of these patients who in addition show a developmental delay (see patient 1). Deletio...

Background: A somatic activating GNAS mutation leads to the triad of café au lait macules, fibrous dysplasia and precocious puberty known as Mc Cune Albright Syndrome (MAS). We present a patient with bone marrow failure as a rare non-endocrine complication of MAS.Clinical case: A 2-year-old girl with neonatal giant cell hepatitis, a large right sided café au lait spot and fibrous dysplasia was diagnosed with MAS. The severe polyostotoc fibrous ...

Objective: To describe six cases of possible partial ectopic posterior pituitary gland (PEPP) seen on head magnetic resonance imaging (MRI) and their associated clinical and endocrinological manifestations.Methods: This is a single-center case series, from a tertiary public university health center in Montreal, Canada. Cases of children with possible PEPP were selected prospectively from 2005 to 2017, based on head MRI findings. Medical history, exam fi...

Introduction: Besides an excessive, early-childhood weight gain, hyperphagia is the key symptom in patients with monogenic obesity. However, the assessment of hyperphagia is still challenging. Here, we applied the hyperphagia questionnaire developed for patients with Prader-Willi-Syndrome (PWS) to assess the severity of hyperphagia in patients with monogenic obesity.Methods: Pediatric patients with biallelic pathogenic l...

Background: Leptin is produced by adipocytes and regulates central hunger and satiety sensation. While the central leptin effects are well understood, little is known about the regulation of peripheral leptin production. Clinical data demonstrate that leptin levels are rapidly declining upon fasting, suggesting that leptin secretion is acutely regulated by nutrient availability. Although it has been previously shown that leptin secretion is under control by gl...
