Introduction: Growth is a complex process influenced by several genetic factors both pre and postnatal, in which 80% of the height variation is explained by genetic factors. Nevertheless, the standard medical evaluation of short stature (SS) relies upon physical examination and laboratory parameters and identifies a pathological cause of SS in 1–40% of individuals. Rearrangements affecting chromosome 15 are rare and affected patients show a variety of nonspecific features...

Background: Leptin is considered to play an important role in the development of hypertension in obesity. The excessive synthesis of aldosterone contributes to the development and progression of metabolic and cardiovascular dysfunctions. Leptin is a newly described regulator of aldosterone synthesis that acts directly on adrenal glomerulosa cells to increase CYP11B2 expression and enhance aldosterone production in human adrenal cells lines and in animal models.<p class="ab...

Introduction: Higher evening cortisol level has been previously described in very preterm infants, possibly reflecting increased Hypothalamic-Pituitary-Adrenal Axis (HPA) tone or alterations in HPA regulation throughout the day. These relatively subtle differences in HPA axis function in preterm compared to full-term children may become meaningful in terms of metabolic risk later in life if sustained over time. Still, only a few studies have investigated wheth...

Introduction: Benign breast pathology has a frequent onset during puberty-adolescence.Objectives: Differential evaluation of breast echostructure in puberty stage III/V, on Tanner scale, depending on the presence of thyroid autoimmunity and hypovitaminosis D.Method: Assessment of BIRADS score from 2 to 4 in three groups of girls associating premenstrual mastodynia: Group 1 - including patients with chronic autoimmune thyroiditis an...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

Background: Congenital adrenal hyperplasia (CAH) is a rare condition characterised by adrenal insufficiency and a life-long risk of adrenal crises. There is a paucity of information on the epidemiology of acute adverse events in this population.Objective: To investigate the frequency, aetiology and consequences of acute adverse events attributed to adrenal insufficiency in CAH.Methods</stro...

Background: Congenital adrenal hyperplasia (CAH) and long-term glucocorticoid treatment may be associated with an increased risk of developing cardiometabolic sequelae such as abnormal glucose homeostasis, hyperlipidaemia, hypertension, cardiovascular (CV) disease, obesity and osteoporosis.Objectives: To study the current practice amongst expert centres for assessing cardiometabolic outcomes in adult patients with 21-hyd...

New developments in massive sequencing techniques allow now the generation of an unprecedented amount of genomic data, including the generation of complete ancient genomes. Among those, the Neandertal and Denisovan genomes, dated between 40 000 and 50 000 years ago, are shedding new light on evolutionary processes such as the genetic basis of archaic hominins and modern humans specific adaptations -including morphological, metabolical and behavioural traits- as well as the ext...

Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...

Background: Iodine concentrations in Chilean schoolchildren are the highest in South America. This may be related to excessive sodium intake, which is associated with hypertension. However, iodine decreases blood pressure (BP), which would be a cardiovascular protective factor.Objective and hypotheses: The objective of this study is to evaluate the effects of iodine on BP and cardiovascular risk factors, despite salt intake.Method:...
