Background: Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia in neonates, infants and children. CHI is a heterogeneous disease in terms of clinical presentation, genetics and histology.Objective and hypotheses: The aim of this study was to describe the clinical characteristics, genotype–phenotype correlations and treatment outcome of Russian patients with CHI.Method: A total of 90 children with CHI were iden...

Objective: The aim of this study was to investigate the incidence of type 1 diabetes in children and adolescents during the Covid-19 pandemic in Germany compared to previous years.Research Design and Methods: Based on data from the multicenter German Diabetes Prospective Follow-up Registry (DPV), we analyzed the incidence of type 1 diabetes per 100,000 patient years in children and adolescents in the year 2020. Using Poisson regression m...

Introduction: Genetic factors play an important role in determining individual susceptibility to weight gain and obesity. In the last few years, several genetic variants have been identified as monogenic forms of obesity. Among them, Leptin (LEP) and its receptor on hypothalamic neurons (LEPR) are key players in the regulation of body weight, food intake and energy homeostasis. Pathogenic variants in the LEPR gene cause severe childhood-onset obesity with an a...

Introduction: Ovarian stimulation syndrome (OSS) in an infrequent disorder, in preterm infants under 30 weeks gestation. The are very few cases described in the literature. The immaturity, lack of gonadal axis feed-back or mutations in the FSH receptor genes, may explain its physiopathology. We present the case of a 26-week neonate with this syndrome.Case summary: 26-week newborn with extremely low weight (460g) born by emergency cesarean section due to ...

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Introduction: Female patients treated with alkylating agents in childhood are at risk for ovarian impairment. We aimed at describing the pattern of residual ovarian function in a cohort of hematological cancer survivors, assessing the relationship between the cumulative dose of alkylating agents administered (expressed as Cyclophosphamide Equivalent Dose - CED) and Anti-Müllerian Hormone (AMH) levels.Methods: Gonada...

Introduction: The co-occurrence of Turner Syndrome (TS) and Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) has been rarely described in literature. The resulting clinical picture includes congenital aplasia of the uterus and of the upper two-thirds of the vagina and ovarian dysgenesis.Case Report: We hereby report the case of a 14-year-old girl referred to our endocrine outpatient clinic for pubertal delay. Her previous medical history ...

Background: Data regarding epidemiology and management of Diabetic Ketoacidosis (DKA) in Italian children with T1D at disease onset are lacking.Method: From 1/1/2012 to 31/12/2013 a survey on DKA was conducted in all paediatric Centres belonging to the Italian Society for Pediatric Diabetology and Endocrinology. DKA was defined according to the ISPAD criteria. The following data were collected: treatment according ISPAD protocol yes or not, type of rehyd...

Background: Type 1 diabetes (T1D) is the most frequent etiology in Italian diabetic children and adolescents. Data on type 2 (T2D) and monogenic diabetes (MD) prevalence are scanty.Objective and hypotheses: To estimate the prevalence of T1D, T2D, secondary diabetes, and MD in a pediatric population of Italian diabetic patients.Method: Data on 3,076 patients (diabetes onset January 2007–December 2012, age at diagnosis <18 y...

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...
