Effect of patient height and weight on sonographically measured renal sizes in a sample of Nigerian adults without known renal disease

To establish some preliminary data of Nigerian population and using ultrasound to determine the renal dimensions [length, width and thickness] with subjects' height and weight. A prospective study of 600 randomly selected healthy adults was carried out. The height and weight of the subjects were measure and results compiled. Three hundred nine were [51.5%] males and 291 [48.5%] females. In males, the mean kidney length was [10.7cm +/- 1.0 and 11.0cm +/- 0.9], while in females, it was 10.4cm +/- 0.9 and 10.8cm +/- 0.9 for the right and left kidneys respectively. There was a strong positive correlation between the renal size, weight and height of respondents thus the prediction of kidney dimensions from the weight and height of individuals was scientifically justified

Ocular volume determination in Nigerians

To determine the ocular volume in healthy Nigerian eyes. This was a cross-sectional descriptive study of volunteers, staff and students of University of Benin Teaching Hospital [UBTH] and University of Benin, Nigeria. Measurements of the eyeball were taken on the B-mode image using a Medison's Sonoace 1500 ultrasound machine using a 6.5 MHz curvi-linear transducer placed over the closed eyelid. The vertical, horizontal and axial diameters of the eyes of healthy subjects were measured and used to compute the ocular volumes. The age and sex of the subjects were also recorded. Two hundred subjects comprising 125 females [62%] and 75 males [38%] were included in the study. The age range was 3-92 years and overall mean age was 41.48 +/- 23.26 years for both sexes. The mean eyeball volume was slightly larger for males than for females. [Males: Right eye=10.64ccm3, Left eye=10.37ccm3; Females: Right eye=10.59 ccm[3], Left eye=10.19 ccm[3]]. The difference was not statistically significant [P= 0.229]. The right eyeball volume was higher on the right for both males and females but the difference was not statistically significant [P= 0.198]. There was a gradual increase in eyeball volume with age. This study was able to generate normal eyeball volumes in a sample of Nigerians which hopefully will serve as reference for normal values in Black Africans
