[Risk of preterm birth in twin pregnancy]. / Ryzyko porodu przedwczesnego w ciazy blizniaczej.

The aim of the study was to analyze the selected risk factors in twin pregnancies. Retrospective analysis was carried out in the Research Institute Polish Mother's Memorial Hospital (ICZMP) in Lodz and covered data from the period of time between 1989-1999. Out of 38,066 deliveries which had place in the ICZMP 538 twin pregnancies were enrolled in the study. We evaluated usual risk factors for preterm birth such as body mass index, short cervical length, beta-mimetics admission, presence of bleeding and contractions as well as socio-demographical characteristics such as age, parity, martial status and educational level. Univariate analysis and ?2 test were preformed. Odds ratios and 95% confidence intervals were calculated. For multivariate analysis logistic regression model was used. Most of the risk factors for preterm birth were not significantly associated with spontaneous preterm birth of twins.

Kurt Benirschke has once written that the placenta provides the most accurate records of prenatal history of foetus. Our study included 104 placentas obtained from pregnancy complicated by diabetes. An obstetrician did the planimetric estimation directly after delivery. A measurement of lesions was conducted with using a special own idea's morphometric grid that allowed us to evaluate a placental surface and a relative size of change statement in a very quick and convenient way. Our method is very useful for making a quantitative estimation of pathological changes in the chorionic plate of placenta.

Kurt Benirschke has once written that the placenta provides the most accurate records of prenatal history of foetus. Our study included 2498 placentas obtained from pregnancy complicated by pregnancy-induced hypertension (PIH), intrauterine growth retardation (IUGR) and epilepsy. An obstetrician did the planimetric estimation directly after delivery. A measurement of lesions was conducted with using a special own idea's morphometric grid that allowed us to evaluate a placental surface and a relative size of change statement in a very quick and convenient way.
