Case Report of Wolf-Hirschhorn Syndrome by Chromosomal Microarray Analysis: Importance of the Molecular Investigation for the Aetiological Diagnosis of Short Stature

Pinto Renata , Pinto Irene , Minasi Lysa , Cunha Damiana , Ribeiro Cristiano , Silva Claudio , Cruz Aparecido

Background: 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. Recent advances in genetic diagnosis are revolutionizing the clinician’s ability to obtain a molecular di...

One Year Use of Anastrazole Improves the Predicted Adult Height of Male Adolescents with and without Associated GH Therapy

Pinto Renata Machado , Goncalves Macks Wendhell

Background: Estrogen is an essential regulator of bone maturation, growth plate fusion, and cessation of longitudinal growth. Aromatase inhibitors (AI) block the conversion of androgens to estrogens, and can be used to delay bone maturation in males.Objective and hypotheses: We sought to determine whether the blockage of estrogen biosynthesis due to the use of the AI Anastrazole increases the Predicted Adult Height (PAH) in boys with short stature.<p...

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...

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...

Anastrozole improves height prediction and near final height as monotherapy or in combination with growth hormone

Machado Pinto Renata , de Almeida Debora Ribeiro , Vitor Percussor Silva Joao ,

Introduction: The wide aromatization of androgens during puberty is responsible for the rapid bone maturation at this age. In this context, the use of aromatase inhibitors (AIs) has been justified by the potential to slow down the advancement of bone age and thus improve growth. For more than two decades, studies have pointed out the validity of AIs to improve the predicted final height (PFH). However, data on near-final height (NFH) of children treated with A...

Case Report of 48,xxyy Syndrome Associated to Father’s Radioactive Contamination During the Cesium Accident in Goiânia – Goiás, Brazil

Pinto Renata Machado , Cunha Damiana Mirian , Ribeiroi Cristiano Luiz , da Silva Claudio Carlos , da Cruz Aparecido Divino

Background: In total of 48,XXYY Syndrome occurs in 1:20.000–1:50.000 male births. It used to be considered as a variant of Klinefelter syndrome, but now it is considered as a distinct clinical and genetic entity with increased risks for congenital malformations, additional medical problems and more complex psychological and neurodevelopmental involvement. 48,XXYY Syndrome results from the fertilization of a normal female oocyte (Xm), with an aneuploid sperm (XpYpYp) produ...

Assessment of DRD2 dopamine receptor gene rs6277 in pediatric obesity: a case-control study

Machado Pinto Renata , Alves Nygell S , Fortes Jakeline S , Monteiro Rubia V , Minasi Lysa B , da Cruz Aparecido Divino ,

Introduction: Obesity is a multifactorial disease resulting from an interplay between genetics and the environment. Metabolic, nutritional, psychosocial, and lifestyle factors participate, promoting various degrees of overweight or obesity. Pediatric obesity increases after infancy and is higher in early adulthood, showing a heritability of up to 85%. Genetic variants associated with BMI in children can exert their effects by affecting eating behavior, as is t...

Mosaicism 47XXX/45X0, a Case Report

Pinto Renata Machado , Duarte Sabrina Sara Moreira , Cunha Damiana Miriam da Cruz e , Ribeiro Cristiano Luiz , Silva Claudio Carlos da , Cruz Aparecido Divino da , Cruz Alex Silva da

Background and Aims: Turner Syndrome (TS), 45X0, is the most common chromosomal pathology affecting females, occurring in 1:2500 to 1:5000 female infants. The typical phenotype includes short stature, gonadal dysgenesis leading to sexual infantilism, low-set ears, low rear hairlin, mamary hypertelorism, neck webbing, gothic palate, irregular rotation of the elbows, shield chest, shortening of the 4th metacarpal, low hairline, shortening of lower extremities, renal disorders a...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

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...
