Introduction: Diabetes insipidus (DI) is a rare disease in children. In most cases it is acquired and central in origin (CDI). The most frequent cause of acquired CDI is brain tumor and idiopathic forms represent between 20-50% of cases, depending on the series. Autoimmune hypophysitis is a rare cause of DI and is a presumptive diagnosis with a suggestive brain MRI and ACTH and TSH deficiencies as the most common hormonal involvement, although it can manifest ...

Background-Aim: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroidogenic pathway of the adrenal cortex. In their most severe forms, they produce adrenal insufficiency and virilization of external genitalia when involving the terminal enzymes of the cortisol and aldosterone synthesis pathway (21-hydroxylase (21-OHD, OMIM#201910) and 11-hydroxylase (11-OHD, OMIM#202010) deficiencies). Mutations of <e...

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...

Introduction: Childhood obesity and insulin resistance (IR) are rising in prevalence, increasing the future adults' cardio-metabolic risk. One of the potential mechanisms behind these alterations is oxidative stress, fruit of increased free radical production and diminished antioxidant defense. Although low plasma vitamin concentrations and oxidative stress have been observed to be associated with obesity in adults and children, their association with IR i...

Introduction: Turner's syndrome (TS) is associated with several manifestations the most frequent being short stature and hypogonadism. Some authors (Nadeem, 2012; Bakalov, 2008) reported that individuals with TS have increased risk of fractures, but the etiology and mechanism of bone fragility have not been yet fully elucidated and may be exacerbated by hormonal factors (Cintron, 2017; Soucek, 2015). Bone densitometry (BD) through the emission of double en...

Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...

Background: Adherence to follow-up visits in children and adolescents with obesity is a key factor for successful therapeutic outcomes in these patients.Objective: To analyze the adherence to scheduled visits and drop-out rate and the anthropometric, metabolic and behavioral outcomes as a result of an intervention program in a large cohort of children and adolescents with obesity.Patients a...

Background: Body mass index not allow to discriminate the proportional composition of the different body compartments: fat mass and fat-free massObjective: The aim of this study is to elaborate standardized values of the fat mass index (FMI) and fat-free mass index (FFMI) in healthy adolescents (both sexes) using anthropometric techniques in order to be available as reference standards in daily clinical practice.<p c...

Introduction: In the last years, the prevalence of high blood pressure (HBP) has increased in children, contributing to raise the risk of future cardiovascular disease. It is known that family history, pregnancy characteristics and type of feeding in the first months of life are of great importance in the prevention of diseases in the offspring. In this study we aimed to investigate the association between early life risk factors and HBP in children and adolescents.<p clas...

Background: We recently reported three children with severe isolated growth hormone (GH) deficiency and pituitary hypoplasia due to biallelic mutations in the RNPC3 gene, which codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. Although it is clear that these patients are GH deficient, the underlying mechanism for this deficit is not totally understood.Objective:...
