Ankle-brachial pressure index estimated by laser Doppler in patients suffering from peripheral arterial obstructive disease.

Ankle-brachial index (ABI) measurements are widely used for evaluating the functional state of circulation in the lower limbs. However, there is some evidence that the value of ABI does not accurately reflect the degree of walking impairment in symptomatic patients with peripheral arterial obstructive disease (PAOD). We investigated the diagnostic value of ABI estimated by means of laser Doppler flowmetry (IT) for evaluating limb ischemia.

[Usefulness of selected ultrasonographic methods for evaluation of fetal weight in twins].

Evaluation of three mathematical methods, based on ultrasound examination, in order to estimate foetal weight in twins and compare them with actual birth weight. Retrospective analysis of ultrasonicly assessed 27 pairs of twin babies, who were born within 10 day of ultrasound examination and then outcome's comparison with newborn weight, measured just after the delivery. The ultrasonic measurements were performed to calculate estimated foetal weight using mathematical models of Shepard, McCallum and Hadlock.
