Background: Klinefelter syndrome (KS) is a genetic disorder consisting in a variable number of additional X chromosomes in a male individual. KS patients can rarely develop peripheral precocious puberty (PPP) caused by extragonadal germ cell cancers (eGCCs) producing hormones with androgenic activity. KS patients are at higher risk for eGCC when compared to the healthy populationCase report: We report the case of M., a 8...

Introduction: Pathogenetic mutations in the HSD17B3, located on chromosome 9q22, lead to 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) isoenzyme deficiency, etiopathogenetic for a disorder of sex development (DSD) with 46 XY karyotype and female phenotype at birth. 17β-HSD3 isoenzyme, expressed at testicular tissue, catalyzes the synthesis of testosterone from Δ4-androstenedione, allowing the correct development of male external genit...

Growth Hormone deficiency (GHD) in newborn is an infrequent condition, which can cause threat to life due mainly to hypoglycemia that begins in the first week of life. A GH basal level (whether random or associated with spontaneous hypoglycemia) that distinguishes infants with GHD from those with GH sufficiency in the neonatal period is not conclusive. Few data have been reported about the GH measurements in serum and dried blood spots on filter paper samples in healthy neonat...

Introduction: NR5A1 (nuclear receptor subfamily 5 group A member 1) is a transcriptional regulator of adrenal and gonadal development and function. Heterozygous and homozygous NR5A1 mutations have been described in 46,XY disorders of sex development (DSD). The clinical, endocrine and genetic features of three 46,XY children from two unrelated families (A and B) with NR5A1 genetic variants are reported.P...

Background: Human GH is a heterogeneous protein hormone consisting of several isoforms, the most abundant being 22 kDa- and 20 kDa-GH. The availability of analytical methods to measure these GH isoforms might represent a valuable diagnostic tool to investigate GH secretion in short stature.Objective and hypotheses: Aim of the present study was to measure circulating levels of 22 kDa- and 20 kDa-GH in children with different diagnosis of short stature suc...

Background: The diagnosis of GH deficiency in children is based on clinical, auxological, radiographic and biochemical criteria which include response to Pharmacological Estimulation Tests (PhT). It is well known that GH concentrations vary according to the assay method used. Currently in our population, the proposed cut-off value of serum GH PhT is 4.7 ng/ml measured by ICMA using the IRP 98/574.Objective and hypotheses: The aims of this study were to d...

Background: The 5α-reductase-2 (5R2) deficiency is a rare 46, XY disorder of sex differentiation caused by mutations in the 5R2 gene. Diagnostic and clinical management is not well definite.Aims and objectives: To describe relevant features of 5R2 deficiency in a large sample.Methods: Retrospective records of persons with 5R2 deficiency were reviewed and clinical, endocrinological, genetic data analysed....

Introduction: The Covid-19 pandemic drastically modified social life and lifestyle in particular among children and adolescents, promoting sedentary behaviors and unhealthy eating habits. In this scenario, the effectiveness of the outpatient approach for pediatric obesity may decrease.Objectives: Aims of this study were to assess the rate and the factors associated with outpatient drop-out by comparing two groups of chil...

Background: systematic data about endocrinopathies in Rett syndrome (RTT) patients are still scarce and not univocal.Objective: to assess the prevalence of endocrinopathies in a pediatric population of RTT patients.Design: retrospective observational single center study.Methods: 29 caucasian patients (28 girls,1 boy) with genetically confirme...

Turner syndrome (TS) patients are at risk for a constellation of neurocognitive and psychosocial diseases. TS is associated with an increased risk for difficulties with visual–spatial reasoning, visual–spatial memory, attention, executive functioning, motor, and math skills. Additionally, increased rates of social difficulties, anxiety, and depression are observed.Here we report the case of a 16-years-old Caucasian girl who came to our attentio...
