[Cervical pregnancy--conservative treatment; case report].

Cervical pregnancy is a rare form of ectopic pregnancy. This disorder appears with frequency 1 to 10 cases of ectopic pregnancy. For the sake of high risk of unexpected massive haemorrhage from cervical vessels, the cervical pregnancy is a life threatening state.

[Fetal pulmonary artery blood flow depending on fetal lung maturity].

The ultrasonographic assessment of fetal lung maturity by evaluating the elasticity of lung tissue, Dynamic Lung Score (DLS) has been being performed since 1986 in ObGyn Department in Tychy (Medical University of Silesia). The lung elasticity is evaluated on the cross sections of fetal thorax, on the level of heart ventricles. The result of the evaluation is given as the three degree scale, in which I degree indicates the lack of elasticity and fetal lung immaturity, II degrees indicates partially expressed elasticity, corresponding with incomplete maturity of lung tissue, and III degrees represents full elasticity and indicates complete maturity of fetal lungs.

[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.
