Premature infants behave similarly in terms of BIVA and most of them have less absolute body water, presenting less fat free mass and fat mass in absolute values, compared to term newborn infants.
BackgroundThe growth of youth with Down syndrome (DS) differs from that of youth without DS, and growth charts specific to DS have been developed. However, little is known about the growth of Brazilian youth with DS. The objective of this study was to construct growth charts for Brazilian youth with DS and compare the growth data with the Child Growth Standards of the World Health Organization (WHO) and charts for children with DS from other studies.MethodsMixed longitudinal and cross-sectional data were collected at University of Campinas, 48 specialized centers for people with intellectual disabilities, and two foundations for people with DS between 2012 and 2015. A total of 10,516 growth measurements from birth to 20 years of age were available from 938 youth with DS (53.7% boys) born between 1980 and 2013. The Lambda Mu Sigma method was applied to construct the curves using generalized additive models for location, scale, and shape.ResultsLength/height-for-age, weight-for-age, and head circumference-for-age percentile curves were generated for Brazilian boys and girls from birth to 20 years of age. Differences in growth of Brazilian youth ranged from −0.8 to −3.2 z-scores compared to WHO standards, and −1.9 to +1.3 compared to children with DS in other studies.ConclusionsThese specific growth charts may guide clinicians and families in monitoring the growth of Brazilian children and adolescents with DS.
Uterine leiomyoma is the most prevalent benign type of gynecological tumor. It affects more than 80% of women worldwide and, within this group, more than 50% may be asymptomatic. However, large fibroid volumes may be associated with symptoms of extrinsic compression, and most of the cases do not present atypical cells. We present the case of a 49-year-old woman who underwent a total abdominal hysterectomy of a 13.5-kg uterine leiomyoma with no malignancies at histopathology and review the literature about giant uterine leiomyomas and their clinical repercussion. We concluded that large volumes do not always pose a threat regarding malignancy; however, future molecular studies are needed to investigate giant uterine fibroids.
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.
