Introduction: Primary Pseudotumor cerebri (PPTC), also known as idiopathic intracranial hypertension, is clinically characterized by increased intracranial pressure in an alert and oriented patient, with no evidence of deformity or obstruction of the ventricular system on neuroimaging. Cerebrospinal fluid analysis is normal except for increased intracranial pressure at lumbar puncture, greater than the 90th percentile (28 cm of H2O) in the pediatric population. Papilledema may...

Introduction: Differentiation between constitutional delay of growth and puberty (CDGP) and congenital hypogonadotropic hypogonadism (CHH) during early adolescence is challenging, as patients exhibit a similar clinical picture and there are no definite clinical or biochemical markers that distinguish these 2 pathologies. A delay in diagnosis, especially for CHH, may have short and long-term health consequences. The aims of this study were: 1) To evaluate the u...

Background: Subjects with non classical congenital adrenal hyperplasia (NCCAH) often present an increased growth velocity secondary to elevation of adrenal androgens that promote early bone maturation and compromise final height (FH). The aim of the study was to analyze prognostic factors affecting growth trajectory and FH in children with NCCAH.Design: retrospective, multicentric studyStud...

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...

Background: Clinical outcome data of patients with adrenal insufficiency, who were affected by COVID-19, have been collected as a common initiative by the ESE Rare Disease Committee and ENDO-ERN via the European Registries for Rare Endocrine Conditions (EuRRECa) project. Methods: This Webropol-based questionnaire included a total of 32 questions collecting quantitative and qualitative data. Of the 19 medical centres out ...

Introduction: 5α-reductase type 2 deficiency (5α--RD) and 17β-HSD type 3 deficiency (17β-HSDD) are rare differences/disorders of sex development (DSD) in which impairment of steroidogenic enzymes causes undervirilisation in patients with a 46,XY genotype. We aim to enlarge the limited knowledge on long-term gonadal function and gonadal pathology in these conditions.Methods: Data on phenotype, laborato...

Background: Congenital Hypopituitarism (CH) is a rare heterogeneous genetic disorder characterized by the deficiency of pituitary hormones. CH can be associated with extra pituitary phenotypes such as midline craniofacial malformations. To date, a minority of patients carry pathogenic variants in more than 30 genes, and thus more than 80% of cases remain unresolved.Objective: To identify de novo pathogenic variants in no...

Background and aim: Congenital growth hormone deficiency (cGHD) is a rare but life-threatening condition whose diagnosis is challenging in the absence of reliable reference values, both in healthy neonates and in preterm ones. We recently estimated GH reference interval in 1036 healthy, at-term newborns (HN) form dried blood spot samples using a previously validated analytical method.Aim: of this study is to provide valu...

Background: The bone age (BA) assess the skeletal maturity and determine the children linear growth. Mexican children have a slightly delay in skeletal maturity before 10 years, but they reach in mean a BA 1 year in advance at the end of the puberty. On the other hand, Mexico has a high prevalence of childhood obesity and the adiposity has been associated with the BA advance in other populations. For the above, the overweight and obesity could be impact in the...

Flash glucose monitoring is now included in the Portfolio of Services of the Public Health System of Andalusia in Spain. We enrolled 145 paediatric T1D diabetes patients into a prospective, interventional study of the impact of the FreeStyle Libre system on HbA1c levels in this population, as well as additional measures of glycemic health, such as Time in Range (TIR) and Time Below Range (TBR). Subjects were trained in use of the FreeStyle Libre system at the start of the stud...
