Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...

Introduction: Previous studies showed that non-obese children and adults with Prader-Willi syndrome (PWS) have a low frequency of metabolic syndrome (MetS), while obese ones have a frequency similar to that of non-PWS obese. It is known that individuals born small for gestational age (SGA) have a greater predisposition to the development of MetS. Recent neonatal percentiles of subjects with PWS (Salvatoni et al, Am J Med Genet Part A, 2019) documented...

Context: The traditional approach to childhood obesity management is lifestyle modification/LSM. Nevertheless, the response rate is variable and difficult to predict.Aim: A systematic search for markers to predict outcomes of simple LSM in pediatric obesity management.Patients/Methods: Out of 240 children with obesity (BMI>97%), recruited to a prospective ‘multi-OMICS’ study granted b...

21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...

Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Background: Neonatal over-nutrition (NON) can increase the propensity to become overweight and develop associated metabolic disturbances in later life. Moreover, some of these long-term effects are sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and triglyceride (TG) and non-esterified fatty acids (NEFA) levels. We hypothesized that the effects would be both age and sex dependant.<...

Background: Glucocorticoids play an important role in the developing fetus, the most important of which is lung maturation by increasing surfactant production and release. Glucocorticoid receptor (GR) functioning changes throughout the fetal period, especially during the transition to extrauterine life. Given the importance of glucocorticoids in lung development and functioning, studying glucocorticoid sensitivity in this population would be helpful, especially in the preterm ...

Background: We have proposed a simple and comprehensive scoring system to evaluate clinical features of differences/disorders of sexual development (DSD); however, its clinical evaluation has not been performed.Aim: To evaluate the association between this newly proposed DSD scoring system (DSD-SS) and assigned gender in patients with 45,X/46,XY mosaicism.Methods: DSD-SS involves e...

Introduction: Term newborns Small for Gestational Age (SGA) have an increased risk for minor neurological impairment at pre- and school age. The general movements (GMs) assessment, in particular at Fidgety (F+) age, has been increasingly used to predict neurological dysfunctions. Aim of our study was to evaluate, in a population of term newborn SGA (gestational age >37 weeks) the growth recovery, the presence of F+ at 3 months of age, and the neurological outcome at 2 year...

Introduction: Consensus guidelines (2021) state that a second dry blood spot (DBS) should be considered for newborn screening (NBS) in preterms (delayed TSH rise).Objective: To evaluate the diagnostic yield of an NBS strategy including a second DBS at 14 days in preterms.Material and Methods: Retrospective study of 2 cohorts. Cohort 1: live births <37 weeks of gestational age (G...
