Background and AimsComputed tomography, which uses ionizing radiation and expensive software packages for analysis of scans, can be used to quantify abdominal fat. The objective of this study is to measure abdominal fat with 3T MRI using free software for image analysis and to correlate these findings with anthropometric and laboratory parameters in adolescents.MethodsThis prospective observational study included 24 overweight/obese and 33 healthy adolescents (mean age 16.55 years). All participants underwent abdominal MRI exams. Visceral and subcutaneous fat area and percentage were correlated with anthropometric parameters, lipid profile, glucose metabolism, and insulin resistance. Student’s t test and Mann-Whitney’s test was applied. Pearson’s chi-square test was used to compare proportions. To determine associations Pearson’s linear correlation or Spearman’s correlation were used.ResultsIn both groups, waist circumference (WC) was associated with visceral fat area (P = 0.001 and P = 0.01 respectively), and triglycerides were associated with fat percentage (P = 0.046 and P = 0.071 respectively). In obese individuals, total cholesterol/HDL ratio was associated with visceral fat area (P = 0.03) and percentage (P = 0.09), and insulin and HOMA-IR were associated with visceral fat area (P = 0.001) and percentage (P = 0.005).Conclusions3T MRI can provide reliable and good quality images for quantification of visceral and subcutaneous fat by using a free software package. The results demonstrate that WC is a good predictor of visceral fat in obese adolescents and visceral fat area is associated with total cholesterol/HDL ratio, insulin and HOMA-IR.
Anquiloglossia, também conhecida popularmente como ¨língua presa¨ é uma anomalia congênita, definida como uma prega mediana localizada no dorso da língua e próximo ao assoalho bucal, que se estende até face lingual da crista alveolar. É constituído por pregas da membrana mucosa, tecido conjuntivo rico em fibras colágenas e elásticas, tecido gorduroso e fibras musculares, além de vasos sanguíneos protegidos por tecido epitelial pavimentoso estratificado. Tem a função de auxiliar na movimentação tridimensional da língua, deglutição, dicção e sucção. Nos casos de alterações congênitas, observa-se limitações dos movimentos linguais, interferências periodontais, ortodônticas, protéticas, além da socialização. A indicação cirúrgica geralmente é diagnosticada por dentistas, fonoaudiólogos e pediatras, podendo ser tratada cirurgicamente em qualquer idade através de técnicas convencionais e outras técnicas descritas na literatura, com auxílio de lâminas frias, eletrocautérios ou laser cirúrgico. O objetivo desse trabalho é relatar o caso de frenectomia lingual de um paciente do gênero masculino de 15 anos de idade.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
