Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Background: Type 1 diabetes mellitus (T1DM) is one of the most frequent chronic diseases in the pediatric age and demands constant and rigorous glycemic control. Intermittently scanned continuous glucose monitoring (isCGM) systems are a helpful tool in diabetes management. Second-generation isCGM contain alarms to assist in the detection of hyper or hypoglycemia. We aimed to compare the sleep quality of principal caregivers of T1DM pediatric patients who use i...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...

Introduction: Growth hormone (GH) treatment is essential for growth in children with GH deficiency. Also short children born small for gestational age (SGA), and children with syndromes like Turner Syndrome (TS), Noonan Syndrome (NS) and Silver Russel Syndrome (SRS) can benefit from GH treatment. For children with needle anxiety GH delivered by a jet device can be a solution for the daily subcutaneous treatment for many years. In 2021, a global recall of the o...

Introduction: Short stature is a frequent reason for consultation in the paediatric age group. After appropriate clinical, radiological and laboratory evaluation, up to 60-80% of children are classified as idiopathic short stature (ISS) because no underlying cause can be found. Nowadays, the spreading of molecular is revealing that many of the patients initially classified as TBI, have variants in genes involved in the growth plate development. IHH gene is inv...

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...

Classic features of inactivating PTH/PTHrP Signaling Disorder 2 or 3 (iPPSD2, iPPSD3), i.e. former pseudohypoparathyroidism include multi-hormone resistance, short stature, subcutaneous ossifications, brachydactyly, and early-onset obesity and a molecular defect at the GNAS region. In addition, patients may present with less-known features including craniosynostosis (CSO).Objective: To describe the prevalence of CSO in a cohort ...

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...
