Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...

Introduction&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...

Background: The Toll-like receptors are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: We aimed to assess the association of TLRs polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: We define the polymorphism of TLR10, rs4129009, rs11096956, rs10004195 in 85 Korean AITD (GD=50, HD=35; M=16, F=69, mean age=12.9 3.1 years)...

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: Growth Hormone Insensitivity (GHI) is characterised by short stature and functional IGF-I deficiency associated with normal/elevated GH levels. Marked genetic and phenotypic heterogeneity exist, and heritable defects in GH-IGF-I axis genes/associated pathways account for mild-moderate to severe GHI cases. We report twin brothers from a non-consanguineous kindred who present with short stature and bi-allelic mutations in QSOX2 encoding the nuclear m...

Background: Throughout 2020 telemedicine was rapidly deployed across health services and, during the COVID-19 pandemic, replaced many face-to-face (FTF) medical consultations. Children and young people (CYP) with diabetes present a unique opportunity for this type of consultation, due to the ability to interpret and share glucose data via other platforms. This study describes both CYP and parent experience of a new telemedicine service for CYP with diabetes.</...

Background: Ovotesticular disorder of sexual development (DSD is a rare form of DSD in which both testicular and ovarian tissues are present in the same individual either in a single gonad (ovotestis) or in opposite gonads with a testis and an ovary on each side.Objective and hypotheses: To discuss rare cases of ovotesticular DSD and one of the novel findings of these cases.Methods and patients: Case 1 is the first child of unrelat...

Background: Wiedemann Steinert Syndrome (WSS) is characterized by distinctive facial features (hypertelorism, thick eyebrows, long philtrum, broad nasal bridge), growth retardation, and intellectual disability of varying degrees. Affected individuals are often born small for their gestational age and have generalized hypertrichosis. Some have growth hormone deficiency, usually partial with normal pituitary MRI. The disease is caused by autosomal dominant varia...

Introduction: Homozygous leptin (LEP) and leptin receptor (LEPR) mutations lead to childhood-onset obesity due to deficient leptin signaling. The specific aims of this work are to explore genotype/phenotype correlations in a national multicenter cohort of 18 subjects with leptin (LEP) and leptin receptor (LEPR) deficiency, report on the long-term clinical follow-up of these rare cases, and systematically review all patients with pathogenic <e...

Introduction: Craniopharyngiomas (CP) are rare pediatric intracranial tumors (1.2-4%) with a peak of incidence between 5-14 years . We retrospectively reviewed data of 16 cases (M/F 4/12) diagnosed before 4 years of age (median follow up 7.2 years) from a cohort of 117 patients (pts) (M/F 56/41) diagnosed after 01/01/2000, followed-up in 14 Italian centres of pediatric endocrinology belonging to the Italian Society for Pediatric Endocrinology and Diabetolo...
