Background: Therapy in type 1 diabetes has undergone a fundamental change over the last several decades, especially by the use of technical devices. Another change that took place is the growing awareness of sex differences of all kind, e.g. as influencing factors of metabolic control. Our study aimed to evaluate sex differences over two decades with regard to changes in glycaemic control, with regard to trends in insulin pump use and insulin dose. Migration b...

Background: Pubertal induction in girls with hypogonadism through estrogen replacement therapy (ERT) aims at the development of secondary sexual characteristics, cognitive functions, uterine growth and maturation, bone mass accrual and linear growth. To date, the best induction regimen, capable of assuring both physiological gradual progression through Tanner stages and effective uterine development, is still to be established.Patients a...

Schaaf-Yang syndrome (SYS) is a genetic disorder caused by truncating pathogenic variants in the paternal allele of the maternally imprinted, paternally expressed gene MAGEL2, located in the Prader-Willi critical region 15q11-15q13. SYS is a neurodevelopmental disorder that has clinical overlap with Prader-Willi Syndrome in the initial stages of life, being the intellectual disability, developmental delay, autism spectrum disorder, neonatal hypotonia, infantile feeding problem...

Background: While differences in gut microbiota between obese and lean subjects have been described, few studies have examined how adiposity across childhood relates to intestinal microbiota composition and diversity in late adolescence.Objective: To explore the correlations between measures of adiposity from childhood and adolescence with intestinal microbiota composition and diversity at 15–17 years.Methods: Data stem from t...

Background: Congenital hypothyroidism (CH) caused by DUOX2 deficiency has a wide range of clinical presentations and phenotype-genotype correlations are not always straightforward.Objective: To describe four children from Quebec with biallelic DUOX2 variants and widely variable phenotypes.Design/Methods: Case series of four children seen for evaluation of thyroid function at the endocrinology service of two university hospitals in ...

Background: Dietary intake has been shown to influence the composition and diversity of the gut microbiota in adults, however its impact in childhood and adolescence remains uncertain. Moreover, the impact of other lifestyle behaviors such as physical activity, sedentary behaviors, sleep and fitness on the gut microbiota has rarely been investigated.Objective: To explore the correlations between intestinal microbiota composition and meas...

Background: Recent studies showed that Rotavirus vaccination may affect the prevalence of type 1 diabetes (T1D). Our aim is to determine the prevalence of early childhood (<5 years) T1D before and during the introduction of Rotavirus vaccination in Israel by syndromic surveillance.Methods: Data on insulin purchases reported by Israel’s four health care organizations (HMOs) was retrieved from the National Program...

Introduction: Endocrinopathies are common features of intracranial germ cell tumours (IC-GCTs), either as presenting symptoms caused by tumour itself or as side effects of treatments.Aims: We examined the development of endocrine dysfunctions in a cohort of paediatric patients with IC-GCTs at diagnosis and during follow up.Methods: We collected clinical, radiological, histopathological and hormonal...

Introduction: Delays in diagnosis of IC-GCTs in the paediatric age have been frequently reported, affecting outcomes and prognosis.Aims: This study analysed clinical features of children with IC-GCTs treated at two European tertiary centres in the last 25 years. We retrospectively reviewed time lag between symptoms onset, radiological findings and definitive diagnosis of IC-GCT.Methods: Presenting ...

Background: Self-limited delayed puberty (DP) is an extreme variant of normal pubertal timing and it often clusters in families. Although it is highly heritable and is the most common cause of delayed puberty, little is known about the genetic control. GnRH neuronal biology has been implicated as a key element in the pathogenesis of DP. By focusing on genes involved in GnRH neuron development, migration and function we may understand more about the genetic bas...
