Introduction: Primary brain tumors are the second most common childhood malignancies, with an increasing survival rate over the years. Late effects on puberty and fertility alter survivors’ quality of life.Methods: We included 204 patients diagnosed with a primary brain tumor before 18 years, followed in pediatric endocrinology at the University Hospital “Necker-Enfants Malades” in Paris between January 20...

Background: Brain tumours are the most frequent solid tumours during childhood. Many of these patients develop endocrine disorders.Objective: To describe our cohort of patients with primary brain tumours, followed in the Pediatric Endocrinology Unit at Hôpital Universitaire Necker–Enfants Malades, Paris, France between 2010–2015, to assess current practice and propose recommendations.Methods: Retrospective a...

Background: Childhood brain tumour survivors are at risk of developing endocrine secondary effects throughout lifetime. Transition between childhood and adult care is a critical moment during which patients may stop medical visits and treatments.Objective: To describe endocrine care transition in our cohort of patients with primary brain tumors followed from 2010-2015, who are ≥=18 years old by December 31st</...

Objective: Craniopharyngioma is a benign brain tumour with frequent local recurrence after treatment. Growth hormone replacement therapy (GHRT) is prescribed in children with growth hormone deficiency due to childhood-onset craniopharyngioma. The objective was to evaluate whether shorter time delay of GHRT initiation after childhood-onset craniopharyngioma completion therapy increased the risk of recurrence.Design: Our r...

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

Background: Hypophosphatemia due to excess urinary phosphate losses and rachitic bone disease occur in several related disorders. The most common form of the heritable hypophosphatemic disorders, X-linked hypophosphatemia (XLH), is due to loss-of-function mutations of the osteocyte/osteoblast protein, PHEX. Reduced abundance of phosphate transporters on the luminal surface of renal tubular cells in the syngeneic animal model of XLH, and inappropriately normal (or frankly low) ...

Background: Nocturnal hypoglycemia is not regularly predictable on the basis of a bedtime BG level and can only be confirmed by BG tests at regular intervals during the night or continuous glucose monitoring (CGM).Objective and hypotheses: A bedtime snack containing carbohydrate as well as fat and protein may be useful in preventing nocturnal hypoglycemia, but this should not be at the expense of high overnight BG levels. In many individuals, a lowering ...

Background: The Fibroblast Growth Factors (FGFs) are a large family of proteins including paracrine, intracrine, and endocrine FGFs. Paracrine and endocrine FGFs interact with specific cell surface receptors (FGFRs) that, via intracellular tyrosine kinase activity, initiate a cascade of downstream intracellular events. Specificity of paracrine/autocrine FGF activity is provided locally by the local production of these FGFs and their cognate receptors. In contrast, endocrine FG...

Background: SWEET (www.sweet-project.eu) is a non-profit entity endorsed by ISPAD aiming to create an extensive network of certified CoRs for childhood diabetes in order to ensure high quality care.Objective and hypotheses: SWEET aims at an improved and more uniform care for people with diabetes through comparing processes and outcomes among participating members. The results of data analysis are conveyed to memb...

Obesity in childhood is associated to several cardiovascular risk factors summarized in the definition of metabolic syndrome such as hypertension, dyslipidemia and impaired glucose tolerance. Besides others, the pathogenetic background is insulin resistance, which deteriorates in mid puberty and normalizes at end of puberty. Accordingly, blood pressure, lipids, fasting glucose and 2 h glucose in oGTT increased from prepubertal stage to pubertal stage and decreased from puberta...
