Background: ROHHAD/ROHHADNET syndrome (rapid-onset obesity with hypothalamic dysfunction, central hypoventilation, autonomic dysregulation with or without neural tumor - NET) – has been reported in association with cerebral venous thrombosis events, as reported also in central hypoventilation syndrome. It is not clear whether thrombotic risk represents a cause or a consequence of hypoventilation and hypothalamic dysfunction. Aim of our study was to chara...

Background: ROHHAD syndrome (rapid-onset obesity with hypothalamic dysfunction, central hypoventilation, autonomic dysregulation) – also defined as ROHHADNET when associated with neural tumors - is a rare condition with a high mortality rate. The aim of this study is to describe the phenotypes of a multicentric cohort of ROHHAD patients.Patients and Methods: We retrospectively analyzed clinical data from 22 patient...

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: Childhood-onset obesity is a multifactorial disease with a lifelong health burden. In many cases, obesity is the result of the interaction between genetic predisposition and environmental factors. Aim of our study was to define phenotypic features of obese children and adolescents and to find possible associations between clinical phenotype and genetic variants.Patients and Methods: We recruited obese childre...

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...

Background: Paragnagliomas and pheochromocytomas are rare neuroendocrine tumors that originate from the paraganglionic cells of the autonomic nervous systems. These tumors may be extra or intra-adrenal in site. The use of antihypertensive medications is usually challenging in these patients. Long acting alpha and beta blockade can be quite useful preoperatively but challenging postoperatively. We present a case of familial paraganglioma that was successfully t...

Introduction: Mutations in Insulin Receptor (INSR) is usually associated with insulin resistance and hyperglycemia. Homozygous or compound heterozygous mutations in INSR are usually linked with Rabson-Mendenhall or Donohue syndromes whilst heterozygous INSR mutations are associated with type A insulin resistance. Various autosomal dominant heterozygous INSR mutations leading to hyperinsulinemic hypoglycemia (HH) have been de...

Introduction: Proton beam therapy (PBT) is being used increasingly for craniopharyngioma, as it is perceived to be a major benefit. There are some limited data relating to endocrine dysfunction following PBT, but very limited data on hypothalamic disturbance. Here we report two patients who presented with hypothalamic disruption immediately following PBT for craniopharyngioma.Case 1: A 12 year old girl presented with sei...

Introduction: Hypomethylation at the imprinting control region 2 (IC2) on chromosome 11p15.5 is the commonest identifiable cause of Beckwith-Wiedemann Syndrome (BWS). IC2 is located in KCNQ1 intron 10 and is associated with Long QT syndrome (LQTS). A recent consensus statement on BWS1 recommends annual cardiac evaluation with electrocardiogram (ECG) in these patients. The natural history of LQTS secondary to hypomethylation at IC2 in BWS is...

Introduction: Noonan Syndrome (NS) is an autosomal dominant condition that affects 1 in 1000 to 2500 live births and is associated with short stature. Studies have shown that height velocity (HV) improved significantly with the use of growth hormone (GH) in the first year of treatment and sustained for the second year. We aimed to look at the effects of GH therapy in our cohort of patients with NS.Method: In this retrosp...
