Background: Approximately 15 million children are born preterm worldwide yearly.Objective and hypotheses: To evaluate spontaneous growth during the first 8 years of life.Hypotheses: Preterm born children have spontaneous recovery of weight and height in the first 8 years of life.Method: Measurements at birth, 6, 12 and 24 months of corrected age and at recall [6.4±0.5 years (5.2–8.0)]. Weight, lengt...

The majority of treated obese children fail the goals set in the medium-long term or do not show themselves up at the short term follow up. These results, which do not improve even with the proliferation of facilities aimed to the treatment of obesity and of its complications, pose serious questions on how to make the best use of scarce resources available by the National health system. We have visited, between 2013 and 2015, 378 seriously obese children (>2 DS from nation...

Background: Familial male-limited precocious puberty, known as testotoxicosis, is an autosomal dominant disease that leads to the activation of luteinizing hormone receptor. It presents with progressive virilization, advanced bone age and linear growth acceleration and may lead to loss in predicted adult height. We report the case of a patient diagnosed with testotoxicosis at two years of age.Case presentation: Two-year-old boy with penis enlargement and...

Introduction: Generally, patients with X-linked hypophosphatemic rickets (XLH) experience normal puberty. However, they can be affected by metabolic and environmental factors that may predispose them to central precocious puberty (CPP) and impair their predicted final height, similar to the general population.Case Report: A female patient was diagnosed with XLH at three and received regular treatment with calcitriol and ...

Background: Rasopathies are a heterogeneous group of diseases that share phenotypic characteristics such as facial dysmorphism, congenital heart disease and short stature.Objective and hypotheses: Evaluation of growth and study of the GH–IGF1 axis. Molecular Study of the PTPN11, SOS1, RAF, KRAS, NRAS, MAP2K1 and MAP2K2 genes. Evaluation of growth and study of the GH–IGF1 axis.Method: Descriptive retrospective study in pat...

Background: ALS deficient (ALS-D) patients present severe IGFI and IGFBP3 deficiencies and variable degree of growth retardation. Heterozygous carriers for IGFALS variants, ALS-D relatives or a subset of ISS children, have levels of IGFI, IGFBP3 and ALS intermediate between ALS-D and wildtype (WT) subjects. This supports that IGFALS gene variants may affect ALS synthesis, secretion and/or function and could be responsible for the observed phenotype.<p cla...

Background: Disorders of Sex Development (DSD) comprise several phenotypes due to dysfunction in genes involved in human sexual determination and differentiation. The most frequent aetiologies among 46,XY DSD are androgen insensitivity syndrome and 5-alpha-reductase type 2 deficiency due mutations in AR and SRD5A2 genes, respectively.Objective and hypotheses: The purpose of this study was to investigate mutations in AR and ...

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: The ideal TSH filter value (TSHf) in the neonatal screening tests for Congenital hypothyroidism (CH) is worldwide controversial. Local cutoff point of TSHf was 9.0 mIU/L until recently. OBJECTIVE: To evaluate the clinical and laboratory characteristics of newborns with CH (confirmatory serum TSH > 10 mIU/L) after a lower TSH cutoff. METHODS: Cross-sectional study using data from Neonatal Screening Reference Center of State Rio Grande do Sul, ...

Background/objectives: Individuals born small-for-gestational age (SGA), especially those who experience postnatal catch-up growth, are at increased risk for developing endocrine-metabolic abnormalities before puberty. In adults, brown adipose tissue (BAT) has been associated with protection against metabolic disorders, such as obesity, type 2 diabetes and dyslipidaemia. Here, we assessed for the first time whether BAT activation differs between prepubertal children born SGA o...
