BACKGROUND/OBJECTIVE Ultrasonogrphy is a good modality for the detection of splenomegaly even when it is not clinically palpable. The objective of this study was to establish the normal values of splenic length in healthy school children in South-East, Nigeria and to correlate them with body indices. MATERIALS AND METHODS This is a cross-sectional prospective study of 1315 children (633 boys ...

According to the published data, endemic goiter was until recently, still present in some regions in Croatia. In this study the thyroid volume in grown-up, student population was measured. It was also analyzed which of the several traditional physiological attributes (body weight, body height, and body surface area (BSA)) were best correlated with the thyroid volume. Fifty one randomly selected...

BACKGROUND M Mode echocardiograms can be measured by two different conventions. In addition, normal limits of echocardiographic measurements have customarily been stratified according to age or body surface area. There is therefore a need to develop a more easily managed approach to calculating normal limits of measurements for the two conventions, one of which, the Penn convention, has not pre...

Accurate individual norms are required for blood volume measurement to be useful in a clinical setting. The primary physiological determinant of normal blood volume is body composition. Norms have been developed based on weight and body surface area, but these have systematic errors arising from variations in body composition or body size. The only norm that specifically estimates body composit...

The relationships of resting metabolism per unit mass of body to gill and body surface areas were examined by measuring gill, body surface and fin areas of carp ranging from 0-0016 to 2250g. There was a triphasic allometry for the relationship between gill area and body mass: during the prelarval (0-0016-0-003 g) and postlarval (0-003-0-2g) stages there was a positive allometry (slopes of 7-066...

Surface area of 201 Japanese (both sexes) from infancy to old age selected statistically by sex, age and body shape were measured and the regional rates calculated and discussed. The results are as follows. 1. There was no difference between either side of the body for age or sex. 2. The rate of head, face and neck decreased while that of the lower extremities increased with aging. 3. After ado...

E nergy requirements, the size of some organs (eg, brain and kidneys), metabolic processes (eg, glomerular filtration rate), and the doses of some drugs (eg, digitalis and chemotherapeutic agents) do not necessarily vary directly with body weight (BW). Some of these factors vary exponentially with BW (eg, BW 0.75 , referred to as metabolic BW) or with body surface area (BSA). Understanding whet...

None of the equations frequently used to predict body surface area (BSA) has been validated for obese patients. We applied the principles of body size scaling to derive an improved equation predicting BSA solely from a patient's weight. Forty-five patients weighing from 51.3 to 248.6 kg had their height and weight measured on a calibrated scale and their BSA calculated by a geometric method. Da...

overall 1906 adult ticks, as well as their nymphs and larvae were collected from the body surface of cattle in the animal husbandries located in north, north-east, south and south-west of ahwaz area, khoozestan, iran, during 1991-1993. the identified adult ticks were hyalomma anatolicum anatolicum (c.l.koch, 1844), hyalomma anatolicum excavatum (c.l. koch, 1844), boophilus annulatus (say, 1821)...
