We report a term male with diazoxide-unresponsive congenital hyperinsulinism (CHI) (spontaneous conception, non-consanguineous, no family history). The patient did not have macroglossia, exomphalos or lateralised overgrowth (cardinal Beckwith-Wiedemann spectrum (BWSp) features) (1). There was no polyhydramnios, macrosomia, facial naevus simplex, ear creases/pits, diastasis recti or nephromegaly/hepatomegaly (suggestive BWSp features) (1).A targeted massi...

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 ...

Objective: KIMS (Pfizer International Metabolic Survey) was a postmarketing surveillance study of growth hormone (GH) replacement in adults and adolescents with GH deficiency (GHD) that concluded in October 2012. This analysis aimed to evaluate the overall safety outcomes from the full cohort of GH-treated patients of KIMS.Methods: Data were collected on adults and adolescents with confirmed GHD and closed epiphyses trea...

Background and Aims: Central Precocious Puberty (CPP) caused by the early activation of the hypothalamic-pituitary-gonadal axis is a rare affection that occurs in 0.2% in girls. Clinical signs are suggestive and LHRH-test could be sometimes difficult to use and not always contributive. Gonadotropin assay in twenty-four hours-urinary collection could be an interesting option. The present work intended to evaluate the diagnostic interest of 24-hour urinary gonad...

Childhood cancer survivors (CCS), particularly brain cancer survivors, are at risk of developing growth hormone deficiency (GHD) due to hypothalamic-pituitary damage from direct tumor mass effects or treatment. Optimization of testing, long-term treatment, and monitoring during care transition from pediatric to adult endocrinology providers remain challenging. A group of endocrinology experts convened to discuss these challenges, the risks and benefits of GH therapy in CCS wit...

Introduction: Severe insulin resistance due to insulin receptor mutation is usually diagnosed at the neonatal period (Donohue and Rabson-Medenhall syndromes), or later in a type A insulin resistance syndrome. We report here two cases of insulin receptor mutation whose presenting signs were less noticeable.Observation: A 13-year-old girl was referred for short stature (Height −2.5 SDS) with SGA (birth length 44.5 cm, at gestational age 41 weeks). Cl...

Introduction: Multinodular goiter (MNG) is a common disorder of the thyroid gland, characterized by thyroid enlargement due to the development of multiple hyperplastic nodules. It is infrequent in children. Here, we present the case of two families with novel DICER1 mutations and familial history of nodules in adolescence.Observations: A 10-year-old female presented a MNG. TSH, Free T3, Free T4 were in the normal range and thyroid autoantibodies were neg...

Background: In 2003 recombinant human growth hormone (rhGH) was approved by European Medicines Agency to treat short children born small for gestational age (SGA), but so far no study evaluated the prevalence of SGA children with short stature who qualify for rhGH treatment in Europe.Objectives: To investigate the prevalence of SGA and short stature in children born SGA and of SGA children who qualify for rhGH treatment ...

Background: Congenital isolated ACTH deficiency (IAD) is a rare inherited disorder that is clinically and genetically heterogeneous. Patients are characterized by low or absent cortisol production secondary to low plasma ACTH despite normal secretion of other pituitary hormones and the absence of structural pituitary defects. Mutations in the TBX19 gene, a T-box factor selectively expressed in developing corticotroph cells, have been identified so far only in cases of neonatal...
