Anti-Mullerian Hormone: a Marker of Premature Ovarian Insufficiency in Girls with Turner Syndrome

Mendes Catarina , Pinho Liliana , Borges Teresa , Oliveira Maria Joao , Cardoso Helena

Background: Turner syndrome (TS) patients typically exhibit short stature and gonadal dysgenesis with pubertal delay and infertility. Up to 30% of these girls will have spontaneous pubertal development, however only 2% achieve a spontaneous pregnancy. Biochemical markers reflecting the ovarian reserve in girls and adolescents with TS are therefore needed.Objective and hypotheses: Evaluation of the ovarian reserve in girls and adolescents with TS using se...

C-Peptide Variation after the Diagnosis of Type 1 Diabetes in Paediatric Age

Correia Joana , Mendes Catarina , Pinheiro Marina , Preto Clara , Cardoso Helena , Oliveira Maria Joao , Borges Teresa

Background: C-peptide secretion is the most accurate measurement of residual β-cell function in type 1 diabetes (T1D) and even residual levels seem to positively correlate with a lower probability of complications.Objective and hypotheses: Identify key determinants to the evolution of the β pancreatic cell function, measured by fasting C-peptide (FCP).Method: Prospective study of patients diagnosed with T1D, with evaluati...

A Novel Mutation of Phex Gene Inducing X-Linked Hypophosphatemia Rickets, A Case Report

Pinto Renata , Francisco Mendes Arthur , Barbosa Julio Montes , Steinmetz Lucas

Introduction: X-linked hypophosphatemic rickets (XHR) is the most common form of hereditary rickets, with an estimated incidence of 1: 20.000 individuals. The main characteristic of the disease is excessive renal phosphate loss, which leads to hypophosphatemia with high phosphaturia and defective bone mineralization.XHR results from mutations in the in the PHEX gene (Phosphate Regulatory Gene with Homology for Endopeptidases located on t...

GH Treatment and First Year Response: A Retrospective Study

Moniz Catarina , Vasconcelos Carlos , Limbert Clotilde , Saraiva Catarina

Background: GH treatment is proven to increase adult final height in some pathology and first year response is assumed as an index of treatment’s effectiveness.Objective and hypotheses: Identify the prevalence of each indication in children treated with GH in our hospital and evaluate the first year response to treatment.Method: We retrospectively analysed the files of 30 patients followed for short stature and on GH treatment...

Klinefelter Syndrome Associated with Short Stature Due to Iatrogenic Cushing

Machado Pinto Renata , Barbosa Julio , Mendes Arthur , Steinmetz Lucas , Cunha Damiana , Divino Da Cruz Aparecido

Introduction: Klinefelter syndrome (KS) is a form of aneuploidy resulting from 2 or more X chromosomes in a male. The most common karyotype is 47, XXY. KS affects physical and intellectual development to varying degrees, commonly causing hypo-development of secondary sexual characters and high stature.Case Report: JLV, male, 3 year 1 month age, the first child of a young non-consanguineous couple, was referred to the ped...

Hypothalamic Gliosis in Obese Children and Adolescents

Sewaybricker Leticia E , Cendes Fernando , Schur Ellen A , Melhorn Susan J , Barbosa Silene M , Mendes Roberto T , Velloso Licio A , Guerra-Junior Gil

Background: Obesity is a persistent disorder that almost universally recurs following treatment, suggesting a disruption on central nervous system control over energy homeostasis. Recent literature suggests that hypothalamic inflammation may have an important role on obesity pathogenesis. This inflammatory reaction, which histologically appears as a reactive gliosis, may be detected using magnetic resonance imaging (MRI), and has just been shown in rodent models and adults.</p...

Severe Obesity – Much More Than an Unhealthy Lifestyle

Matias Joana , Amorim Marta , Limbert Catarina

Introduction: Pediatric obesity is an important public health problem. Exogenous obesity represents most cases; in some children, obesity is attributable to endocrine or genetic disorders. Genetic etiology should be considered in children with dysmorphic features, global developmental delay, early onset severe obesity (before 5 years), hyperphagia or severe obesity family history. Regardless of the etiology, treatment must begin with long-term lifestyle change...

Congenital Adrenal Hyperplasia with a CYP21A2 deletion overlapping Tenascin-X gene

Rodrigues Ivo Catarina , Fitas Ana Laura , Madureira Ines , Diamantino Catarina , Gomes Susana , Goncalves Joao , Lopes Lurdes ,

Introduction: Congenital Adrenal Hyperplasia (CAH) is a group of genetic diseases characterized by impaired cortisol synthesis. 95% of CAH cases result from mutation in the CYP21A2 gene encoding 21-hydroxilase. TNX-B gene partially overlaps CYP21A2 and encodes a matrix protein called Tenascin-X (TNX). Complete tenascin deficiency causes Enlers-Danlos syndrome (EDS). A variant called CAH-X, has recently been described, resulting from CYP21...

Normosmic Hypogonadotropic Hypogonadism: An Intrafamiliar Case

Soares Joana , Briosa Filipa , Valsassina Rita , Amorim Marta , Limbert Catarina

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

Cardiometabolic Effect of Sugar-Sweetened Beverages Reduction in Obese Children

Galhardo Julia , Diamantino Catarina , Alonso Anabela , Lopes Lurdes

Background: The excessive consumption of sucrose, primarily used in sweetened beverages, has been considered an important inducer of cardiometabolic diseases. Besides the association between metabolic syndrome and fructose found in animal models, literature is lacking prospective studies in humans, especially in paediatric ages.Objective and hypotheses: We assessed the effect of sugar-sweetened beverages reduction on markers of metabolic syndrome in obes...
