Background: Polycystic ovary syndrome (PCOS) is a complex endocrine genetic disorder, which is associated with increased metabolic and cardiovascular morbidity. Vitamin D or omega-3 fatty acids supplementation may alleviate the metabolic and reproductive complications of PCOS.Objective and hypotheses: To compare clinical, psychometric, biochemical, endocrine, bone and sonographic markers in vitamin D sufficient adolescents with PCOS, pre- and post- 6 mon...

Objectives: In laboratory medicine, external quality assessment (EQA) schemes have become versatile tools for the detection of analytical flaws. However, for pediatric sex steroid levels EQA schemes are lacking. We aimed to investigate the suitability of different estradiol and testosterone immunoassays in a pediatric setting, in comparison with clinical liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays.Methods:</s...

Background: Obesity in childhood and adolescence represents a major health problem of our century that has reached epidemic proportions globally during the last decades. In obese subjects, a relatively high cortisol output in urine has been observed compared to nonobese individuals. However, cortisol concentrations in blood, saliva, and urine in association with obesity have not been consistent across studies. Hair cortisol concentrations (HCC) determined in scalp hair provide...

Background: Little data exist regarding the hypothalamic-pituitary-adrenal (HPA) axis activation and the interplay between the HPA axis and markers of pro- and anti-oxidation in children, following an acute aerobic exercise bout in children.Objective and hypotheses: To investigate the changes of HPA axis hormones following an acute bout of aerobic exercise and their respective association with markers of pro- and anti- oxidation in normal weight and obes...

Aims/hypothesis: The Wolfram syndrome, also known as the DIDMOAD syndrome (Diabetes Insipidus, early-onset Diabetes Mellitus, progressive Optic Atrophy, and Deafness), is mostly associated with recessive mutations in the WFS1 gene. However, dominant mutations in the WFS1 gene were described as causing less severe Wolfram-like syndrome, or isolated optic atrophy, or low-frequency sensorineural hearing loss.Method...

Background: Several studies have shown that type 1 diabetes mellitus (T1DM) may contribute to the early onset or acceleration of cognitive impairment (intelligence, psychomotor efficiency, information management speed, visual attention, visual perception and cognitive flexibility). Tear proteomics seems to provide useful information for understanding the molecular mechanisms of various ocular and systemic diseases.Objective and H...

Background: X-linked hypophosphatemia (XLH) is caused by mutations in PHEX which increases serum Fibroblast Growth Factor 23 (FGF23) concentrations leading to phosphate wasting and osteomalacia. Burosumab is a recombinant fully human IgG1 monoclonal antibody which selectively inhibits the activity of FGF23. In clinical trials burosumab demonstrated significant clinical improvements in radiological rickets severity, growth, and biochemistry among XLH c...

Introduction: Maternal perinatal mental disorders (PMDs) are associated with developmental and behavioral problems in the offspring, probably mediated by the programming of the limbic-hypothalamic-pituitary-adrenal (LHPA) axis. Increased or decreased cortisol concentrations during pregnancy and the perinatal period have been associated with alterations in the stress responses of the offspring and with child behavioral problems; however, such associations remain unclear.<p ...

Background: Thyroid dysgenesis has been considered a sporadic disease, but recent observations suggested a possible genetic basis.Objective and hypotheses: The aim of our report is to evaluate the incidence of hormonal and ultrasound thyroid anomalies in siblings of CH patients with thyroid dysgenesis.Method: In Emilia-Romagna Region (Italy) 328 CH infants were diagnosed by neonatal screening between January 2000 and December 2012....

Background: At present few data have clearly showed an increased frequency of idiopathic central precocious puberty (CPP) in females during the COVID-19 pandemic. The role of environmental factors is not fully understood and various hypotheses have been formulated.Aims of the study: To evaluate retrospectively the incidence of newly diagnosed CPP and other pubertal disorders (Premature thelarche, early puberty, fast pube...
