Aim: To assess the efficacy of faster aspart (FIAsp) in paediatric population with type 1 diabetes mellitus (T1DM) and insulin pumps in real-world settings.Methods: We conducted a prospective analysis of 16 children and adolescents with T1DM on insulin pump that switched from Aspart to FIAsp from September 2019 to June 2020. We performed within groups and between groups analyses in three time points: 3 months before FIAs...

Background: Undescended testes in patients with defective mini-puberty contain germ cells that fail to differentiate normally into Ad spermatogonia and ultimately leads to infertility. Six months treatment with the gonadotropin-releasing hormone GnRH increases luteinizing hormone and testosterone secretion and rescues fertility in the majority of pathological cryptorchid testes. Several Y chromosomal genes in the male-specific Y region (MSY) are essential for spermatogenesis, ...

Background: Onset of diabetes in the neonatal period with additional malformations e.g. congenital heart defects should always be suspicious for an underlying genetic disorder. For example, GATA6-mutations were identified in children with congenital heart defects and neonatal diabetes. The latter may be due to pancreas agenesis. Herein we present a novel GATA6-mutation in a boy with transient neonatal diabetes, diaphragmatic hernia, congenital heart defect and early onset scol...

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Background: Significant changes in metabolism and water equilibrium are registered during pregnancy. However, very limited previous investigations have been carried out on variations of exposure levels and metabolism of non-persistent environmental chemicals during pregnancy.Objective and hypotheses: The objective of this longitudinal study is to describe variation in exposure of pregnant women to environmental chemicals. We hypothesise that variation in...

Objectives: We designed a longitudinal study to investigate the association between central pubertal activation with age at the appearance of clinical signs of puberty. We, therefore, assessed nocturnal gonadotropin secretion which can be detected in the form of total luteinizing hormone (LH) immunoreactivity in the daytime- and sleeptime-excreted urine.Methods: Thirty healthy volunteers (17 boys and 13 girls, aged 3.4&n...

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

Background: The excessive consumption of sucrose, primarily used in sweetened beverages, has been considered an important inducer of cardiometabolic diseases. Besides the association between metabolic syndrome and fructose found in animal models, literature is lacking prospective studies in humans, especially in paediatric ages.Objective and hypotheses: We assessed the effect of sugar-sweetened beverages reduction on markers of metabolic syndrome in obes...

Background: Several studies have suggested that vitamin D supplementation in early childhood is successful in decreasing the risk of type 1 diabetes (T1D) through a complex immunomodulatory role. However, Intervening in disease once clinical symptoms have appeared and autoreactive immune responses are active might be more challenging. Controlled trials with vitamin D supplementation in recent-onset T1D have shown mixed results.Objective and hypotheses: T...

Background: Testicular tumours are an unusual cause of prepubertal gynecomastia. However, in boys with Peutz-Jeghers Syndrome (PJS), a rare autosomal dominant disorder caused by mutation in LKB1/STK11 gene, is mandatory to exclude this etiology, given the well-known association between PJS and Large-Cell Calcyfing Sertoli-Cell Tumor (LCCSCT). This mutation promotes aromatase overexpression in neoplastic Sertoli-cells, leading to gynecomastia.Case present...
