Background: Patients with Turner Syndrome (TS) are at high risk for congenital heart disease (CHD), aortic dilatation and dissection with increased mortality and morbidity. Thoracic gadolinium-enhanced MRI angiography allows clear imaging of all great vessels and revealed a spectrum of silent vascular anomalies (VA), both venous and arterial, undetected at Echocardiography.The aim of this study is to retrospectively evaluate the prevalen...

Background and aim: Children with premature adrenarche (PA) have often tall stature, advanced bone maturation, and a tendency to be overweight. It has been speculated that PA may lead to unfavourable outcome, including obesity-related metabolic disturbances, but the data on long-term outcome of PA are insufficient. The aim of this work was to describe adult body composition in young females with a history of PA.Subjects and design: This prospective case-...

Background: Very early onset diabetes mellitus (neonatal diabetes mellitus (NDM)) seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with NDM, some of which have been elucidated at the molecular level. Among these, the recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic KATP channel involved in regulation of insulin secretion, account for one...

Management of type 1 diabetes in preschool children is a huge challenge for their caregivers. Age-specific factors (e.g. unpredictable food intake and physical activity, small insulin doses, high insulin sensitivity, frequent intercurrent infections, high variability in insulin requirements) increase the complexity of daily diabetes management. Furthermore, the preschool child depends completely on his/her caregiver. To meet recommended treatment targets while avoiding hypogly...

Background: DAVID syndrome (deficit in anterior pituitary function and variable immune deficiency) (J Clin Endocrinol Metab 97 E121, 2012) can be caused by NFKB2 mutations (Am J Hum Genet 93 13, 2013). All patients have an orthotopic posterior pituitary (PP) and most only ACTH deficiency.Objective and Hypothesis: To describe a girl with common variable immunodeficiency (CVID), ectopic PP (EPP) ...

Background: An early diagnosis and treatment based on neonatal screening offers a normal cognitive development in patients affected with congenital hypothyroidism (CH). However, several studies within cohorts of young adults have shown a still existing difference compared to control groups of up to eight IQ points. Moreover it has been claimed recently that a high L-T4 dose with subsequent episodes of overtreatment results in less favourable IQ outcom...

Background: Hyperthyroidism is uncommon in children. Graves’ disease is the most common cause in pediatric population. The diagnosis is based on the presence of anti-TSH receptor antibodies. Pediatric Graves’ disease has some peculiarities mainly in term of treatment and evolution, since its prognostic is different than adults.Aim: The aim of this study is to describe the epidemiological, clinical and biological features of pediatric Graves...

Background: Most published studies on 46,XY DSD focused on genetic findings without association with biochemical work-up.Objectives: To retrospectively analyze the clinical and genetic findings of a large cohort of 46,XY DSD patients.Methods: 285 non-syndromic 46,XY DSD individuals (192 sporadic and 89 familial cases) were studied. LH, FSH, testosterone (T), androstenedione (A) wer...

Introduction: Gonadotoxicity associated with chemotherapy of hematologic malignancies has been described mainly in adults, focused on the sensitivity of germ cells. Little attention has been placed on Sertoli cells during childhood and puberty, even though Sertoli cell development is essential for adult spermatogenesis.Objective: To assess function of the pituitary-testicular axis, with emphasis on Sertoli cell function,...

Background: PAPP-A2 is a metalloproteinase that specifically cleaves IGFBPs 3 and 5. Papp-a2 knock-out (KO) mice show a reduction in body size and skeletal abnormalities.Objective and hypotheses: Our objective is to report two affected families from Spain and USA. The Spanish family presents a homozygous frameshift mutation in exon 3 of the PAPP-A2 gene (c.1927_ 1928insAT, p.D643fs25X) resulting in a premature stop codon, with 2 of 4 si...
