[Pregnancy in a patient with Turner syndrome].

Fertility in patients with a diagnosis of Turner's syndrome confirmed by karyotype examination is a very rare phenomenon. Only in 2% of all cases the pregnancy is a result of a spontaneous ovulation and intrauterine fertilization. Due to high proportion of complications occurring in pregnancy, in labour and in puerperium, only minority of patients can expect delivering a healthy infant.

[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.
