Estimations of body surface area in newborns

Acta Paediatrica, 2008
AbstractAim: To explore the suitability of existing formulas to estimate the body surface area (BSA) of newborns when direct measurement of surface estimation is not practical.Methods: In 589 term‐newborns of normal weight and height, the five estimations (in cm2) were performed using four known BSA formulas by Boyd, Meban, Mosteller and Dubois, and ...

Body surface area in the infant rat

Journal of Applied Physiology, 1975
Body surface area (SA), one index used to minimize size differences in metabolic studies, was estimated by a coating method in rats aged 1, 7, 14, and 21 days (d) (n = 100–107). Body weights (BW) at each age varied about twofold. Regression equations were calculated for SA (cm2) vs. BW (g) (SA = 8.73 + 2.29 BW, 17.79 + 1.71 BW, -4.92 + 2.16 BW, and 53.

On surface area measures of convex bodies

Geometriae Dedicata, 1980
The set Lj of jth-order surface area measures of convex bodies in d-space is well known for j=d−1. A characterization of Lj was obtained by Firey and Berg. The determination of Lj, for j∈{2, ..., d−2}, is an open problem. Here we show some properties of Lj concerning convexity, closeness, and size.

Body height, body mass and surface area of the Neandertals

Zeitschrift für Morphologie und Anthropologie, 1998
Body size, expressed as height or stature, is an important determinant of many other biological variables. Thus, it is surprising that many textbooks portray a wrong picture of Neanderthal height as being "very short" or "just over 5 feet". Based on 45 long bones from maximally 14 males and 7 females, Neanderthals' height averages between 164 and 168 ...

Body Surface Area Misconceptions¹

Risk Analysis, 1993
In this letter to the editor, the author discusses methods that have been used to measure body surface area and some of the assumptions which have been made in the measurements. Proposals for interspecies extrapolation formulas that rely on surface area measurements make two assumptions: that the surface area is relevant and that the surface area has ...

Measuring the Surface Area of a Convex Body

The Annals of Mathematics, 1944
In applied sciences it is sometimes desirable to measure the surface area of a small body. It is difficult to do this directly, but if the body is convex we may use a well-known theorem on convex bodies. If K is such a body in threedimensional space, let S be its surface area, A (n) the area of its projection on a plane perpendicular to the vector n ...

Body Surface Area Teaching in Pediatrics

JAMA: The Journal of the American Medical Association, 1967
To the Editor:— Much literature has appeared in recent years on the subject of body surface area (BSA). 1-8 In spite of the fact that various textbooks and brochures present drug dosage in terms of BSA, there has been, to our knowledge, no considered attempt to learn how widely the subject is being taught in medical schools.

Body Surface Area in Galeoid Sharks

Copeia, 1990
Standard length (SL), girths (G) and body surface areas (SA) were measured on 47 specimens comprising 10 species of galeoid sharks ranging in SL from 51-354 cm. Analysis of covariance showed that even closely related species had statistically different regressions of surface area on length.

Measures of Body Surface Area in Children

2012
Body surface area (BSA) is an important index of body size in both adults and children. The use of BSA allows for standardization of the important physiological parameters such as cardiac function, glomerular filtration rate and proteinuria, which are indexed by BSA. This in turn enables comparison of these parameters among children of various ages and
