Pancreatic β cells develop from endodermal pancreatic progenitors that first proliferate and next differentiate into functional insulin-producing cells. This developmental process is complex, each step being controlled by yet unknown signals. Theoretically, the development of a functional β cell mass can be enhanced by: i) activating the proliferation of pancreatic progenitors; ii) activating their differentiation into β cells; iii) activating the proliferation ...

Background: Short stature is a recognized complication of Crohn’s disease (CD) in children. Less is known on the impact of disease on final adult height and body proportions.Objective and hypotheses: To assess height and body proportions in 48 adults (F: 30; M: 18) with childhood (ACO) or adult (AAO) onset CD and 44 children (C) (F:22; M:22) with CD.Method: Standing, sitting height (SH) and leg length (SILL) were measured and ...

Objective: Obesity and its complications affecting many organ systems have been documented. Nevertheless, study conducted on the ophthalmological effects of obesity are scarce. The aim of the present study was to evaluate the changes in the ophthalmological parameters in obese children in comparison to their healthy counterparts.Material and methods: Study included 61 obese and 35 age-sex matched controls. Obesity was defined as body mass index- standard...

Objective: Spexin is a novel peptide implicated in food intake and satiety. Spexin levels are reduced in obese patients.Aim: To evaluate the associations of metabolic syndrome (metS) antecedents with serum spexin levels in obese adolescents.Setting: A university- based tertiary care centre.Patients and methods: Eighty consecutive obese adolescents aged 10-18 y and 80 healthy ...

Background: Cigarette contains more than 4,000 toxins and is suspected of having endocrine-disrupting properties. Anogenital distance (AGD) is an important biomarker of fetal androgen exposure and intrauterine masculinization. There are limited number of studies examining whether AGD is affected by prenatal smoke-exposure. The aim of this study is to investigate the effects of maternal smoking during pregnancy on newborn infants' AGD.<p class="abstext"...

Background/aims: The high complexity of Pediatric reference ranges across age, sex and units impairs clinical application and comparability of steroid hormone data, e.g., in CAHs. We developed a Multiples-of-Median (MoM) normalization tool to overcome this major drawback in Pediatric Endocrinology.Methods: LC–MS/MS data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to >16 years) from two previous datasets we...

Central hypothyroidism (CeH) is characterized by thyroid hormone deficiency due to impairment of pituitary TSH or hypothalamic TRH biosynthesis. CeH is often seen as a part of multiple pituitary hormone deficiencies, but it can also be seen as isolated. Diagnosis may be challenging. To date, some variants that can cause isolated CeH have been identified; although in a number of patients the cause has not been clarified. Recently, variants of the insulin receptor substrate 4 (<...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

Background: Subclinical hypothyroidism (SH) is defined as normal tyrosine levels in the presence of TSH concentrations between 5 and 10 mU/ml. The impact of SH on IGF system and growth of infants remains unknown.Objective and hypotheses: To evaluate IGF1, IGFBP3 levels and growth velocity (GV) of infants with SH.Method: 98 children up to 36 months of age, recalled due to a TSH >5 mU/ml in the neonatal screening test, were divid...
