Capillary hyperglycemia in critically ill infants is a situation with numerous interfering factors, from acute illnesses to concomitant use of medications and may or may not be a manifestation of endocrinological urgency. Clinical case: Female patient, 2 months old, with failure to thrive, hepatomegaly without cholestasis, polyuria and compensated metabolic acidosis. On admission, capillary blood glucose levels above 200 mg/dL were measured even without concomitant use of cort...

Failure to thrive is a term used to describe inadequate growth or the inability to maintain growth, which usually occurs in early childhood. Case report: female patient, 7 months old, referred to the pediatric clinic of Hospital de Clínicas de Porto Alegre due to a possible syndromic condition. He had no diagnosed comorbidity to date and was using only prophylactic ferrous sulfate and vitamin D. No family history of similar illness. Physical examination showed hypertric...

Introduction: Dyslipidemia secondary to obesity is a risk factor related to cardiovascular disease events, however a pathological conventional lipid profile (CLP) is infrequently found in obese children. The objective of our study is to evaluate the advanced lipoprotein profile (ALP) and its relationship with cardiac changes, metabolic syndrome and inflammatory markers in a population of morbidly obese adolescents with normal CLP and without type 2 diabetes me...

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: Angiopoietins are necessary for development, differentiation and stabilization vessels progress. Angiopoient 1 (Ang-1) is responsible for vascular integrity, through stimulation of endothelial cell migration and adhesion, and inhibition of apoptosis. Action of angiopoietin 2 (Ang-2), in the absence of VEGF it Leeds to vascular regression, but in the presence of high VEGF concentration it stimulates angiogenesis. Stromal derived factor (SDF-1) play an important ro...

Background: Most congenital adrenal hyperplasia (CAH) patients carry mutations derived from conversion events involving the pseudogene, and the remaining carry new mutations varying according to ethnicity. A good genotype-phenotype correlation is observed, allowing the use of molecular analysis in clinical practice.Objective and hypotheses: To review the molecular diagnosis in a large cohort of CAH patients in order to create a diagnostic panel in our po...

Background: Loss-of-function mutations in the imprinted gene MKRN3 represent the most common known genetic defects associated with central precocious puberty (CPP). The penetrance of these mutations remains to be established. To date, all reported individuals with MKRN3 mutations were already in puberty or postpubertal and were identified retrospectively.Objective and hypotheses: To report the first case of a prepubertal child with an MKRN3 muta...

Background: Acromesomelic dysplasia Maroteaux type (AMDM) (OMIM 602875) is a rare autosomal recessive skeletal disorder with an approximate prevalence of 1/1,000,000) and characterized by severe dwarfism accompanied by shortness of distal and middle segments of extremities. Mutations in the NPR2 gene which encodes for the natriuretic peptide receptor B (NPR-B) is the underlying genetic cause of this disorder.Objective and hypotheses: Genetic con...

Background: We recently identified loss-of-function mutations in makorin ring finger 3 (MKRN3) as a cause of familial central precocious puberty (CPP). Analysis of Mkrn3 expression in the arcuate nucleus of mice showed high expression levels in juvenile mice, with a marked reduction prior to puberty onset, suggesting that MKRN3 inhibits puberty initiation. The function of MKRN3 is not known but based on its amino acid sequence, it is predicted to act as an ubiquitin l...

Background: In Brazil there is a nutritional transition between child malnutrition and increasing prevalence of obesity.Objective and hypotheses: The study aims to identify the prevalence of overweight and obesity in children aged 5–18 years in five private and 15 public schools from city of Uberaba Brazil.Method: Anthropometric data, inventorys physical activities and socioeconomic aspects were evaluated from 1125 individuals...
