Introduction: The diagnosis of growth hormone deficiency (GHD) is currently based on clinical, auxological, biochemical, and neuro-radiological investigation. Provocative tests of GH secretion using physiological/pharmacological stimuli are required to confirm GHD. The clonidine test (CT) is widely used to assess GH secretory status. In this retrospective study we analyzed the reliability of CT and the effect of puberty in a large number of children with short stature who had ...

Background: ROHHADNET syndrome affects children with normal development until 2–4 years of age.Objective and hypotheses: Aim of this study was to evaluate a possible role of autoimmunity in this disorder. In spite of a suspicion for genetic etiology, disease-associated genetic variations have not been identified. A paraneoplastic/autoimmune etiology has been suggested mainly because of the association with neural crest tumors....

Introduction: X-linked hypophosphatemia (XLH) is a rare hereditary condition caused by mutation in the gene encoding the phosphate-regulating endopeptidase homolog, X-linked (PHEX). It is characterized by altered phosphate homeostasis with persistent hypophosphatemia and hyperphosphaturia resulting in deficient skeletal mineralization, rickets, bone deformity, growth failure, dental problems, joint pain and impairment.Case Prese...

There is little information on metabolic profiles and Body Composition in children with Silver-Russell syndrome (SRS).Methods: 31 SRS patients [16 subjects with 11p15 loss of methylation (11pLOM) and 15 subjects with maternal uniparental disomy of chromosome 7 (mUPD7); mean age 7.4±4.3 years] and non-SRS subjects [34 small for gestational age (SGA), 13.4±2.7 years, and 44 appropriate for gestational age (AGA), 6.9 ± 1.4 ye...

Dual-X-ray-Absorptiometry (DXA) bone parameters in children with Achondroplasia

Achondroplasia is the most common skeletal dysplasia caused by a gain of function of the fibroblast growth factor receptor 3(FGFR3) that impairs endochondral ossification, exiting in short stature and altered bone microarchitecture. Although fractures and reduced bone mineralization are not comorbidities frequently reported, specific normative DXA data are lacking. Aim of the study was to assess bone density parameters in an Achondroplasia cohort. Fifty-seven patients (Female-...

Background: Hypergonadotropic hypogonadism (HH) is an hallmark of Turner Syndrome (TS) and hormone replacement therapy (HRT) is often required for pubertal induction; this retrospective study highlights the pituitary-gonadal axis during infancy (<5 years), childhood (5–10.9 years) and adolescence (> 11 years) in a cohort of TS patients enrolled between February 1999 to March 2023. Our aim is to underline the diagnostic role of Gonadotropins as a ma...

Introduction:Up to 20% of children with neurofibromatosis type 1 (NF1) develops low-grade optic pathway gliomas(OPGs) that can result in neuroendocrinopathy.The aim of the study was to identify prognostic factors for developing neuroendocrinopathies in patients with NF1 and OPGs before any treatment.Methods: Records of 117 children with NF1 and OPGs followed at 4 Italian centers between 1997-20...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by inactivating mutations in the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene, characterized by chronic hypophosphatemia. XLH children present with progressive skeletal deformities (leg bowing, waddling gait, poor growth and disproportional short stature), dental abscesses, and craniosynostosis. Most affected children have been treated so far with multiple dail...

Central diabetes insipidus (CDI) in children is caused by brain tumors, Langerhans cell histiocytosis (LCH), trauma, infections, or genetic abnormalities in about 60% of the cases. In the remaining 40%, CDI is idiopathic even after detailed clinical and radiological investigations. Aim of the study was to assess whether measurement of serum antibodies against human growth hormone (GH) could aid in the identification of the etiological factors for CDI.<p class="abst...
