Aim: The aim of the study was to determine the content of cadmium and lead in different parts of the placenta and fetal membranes of women who were exposed to cigarette smoke. The correlation between the two chemical elements and the impact of the Cd and Pb accumulation on newborn parameters were established., Materials and Methods: The study material was collected immediately after delivery from 40 patients of the Department of Obstetrics and Gynecology Katowice. The marginal and central parts of the placenta and fetal membranes (amnion) were taken. The women were divided into two groups: smokers and non-smokers. Metal concentration in placenta was determined by flame atomic absorption spectrometry (FAAS). Bioethical Commission approved of the study, Results: In both studied groups, smokers and non-smokers, the presence of cadmium and lead was detected. Smokers turned out to have accumulated more of the investigated heavy metals in the placenta and fetal membranes. In the analyzed groups of women of smokers and non-smokers, differences in the content of the studied metals were found, but they were not statistically significant. Differences in newborn parameters in the two groups of women occurred, but again they lacked statistical significance. The level of lead increases along with the increase in the amount of cadmium, which proves the existence of a statistically significant correlation between them (p = 0.000)., Conclusions: The number of smoked cigarettes increases cadmium content in maternal placenta and fetal membranes. No significant differences in newborn parameters of either smoker or non-smokers were observed, which may indicate women's adaptation to the environment containing cigarette smoke. The placenta and fetal membranes are biomarkers of the level of toxic exposure for the developing baby.

A germinal matrix is an area of the fetal brain where neuroblasts proliferate till the 20th week of gestation after which their migration takes place. Germinal matrix hemorrhage (GMH) is a frequent cause of fetal ventriculomegaly or hydrocephalus, yet the pathophysiological conditions of GMH remain unclear. A case of fetal ventriculomegaly resulting from GMH has been reported in the article. A prenatal ultrasonographic examination (US) carried out in the 30th week of gestation revealed enlarged ventricles. Utero magnetic resonance imaging (MRI) performed in the 34th week of gestation demonstrated asymetric ventriculomegaly and the changes suggesting the occurance of GMH and ependymal intraventricular hemorrhage. Fetal ventriculomegaly and hydrocephalus are commonly detected by ultrasonographic examination, but it is often difficult to determine the causes of the diseases by US. In these cases MRI allows to establish the final diagnosis.

The cytomegalovirus infection is most common causes of intrauterine infection of the fetus. Using of serologic diagnostic methods the kind of infection is unknown. The aim of the study was assessment of the risk of CMV infection depending of genome account in mother's blood and I amniotic fluid. The study was performed in choosen pregnancies, in which we expected cytomegalovirus infection using serological criteria. In prenatal diagnostic CMV infection using QPCR, the best material is amniotic fluid. Mother's blood assessment of CMV genome count does not make growth diagnostic possibility of the assesement of transmission the infection from mother to fetus.

Objectives: Toxoplasma gondii infection during pregnancy is still a difficult problem in the contemporary perinatology. Difficulties met during interpretation of serological tests carried out in pregnant patients to detect Toxoplasmosis implies more and more frequent use of the Polymerase Chain Reaction (PCR)., Design: To evaluate the dependence between serological tests and quantity of the Toxoplasma gondii genomes in mothers' blood and amniotic fluid or neonatal blood, the quantitative PCR (q-PCR) method was applied., Materials and Methods: The analysis was performed in 81 pregnant women. Maternal blood, amniotic fluid and newborns' umbilical blood samples were evaluated for the presence of Toxoplasma gondii DNA. IgG and IgM Toxoplasma gondii antibodies were evaluated by the ELISA method., Results: High seroprevalence (51.9%) of the Toxoplasma gondii was confirmed. Toxoplasma gondii genetic material in blood and/or amniotic fluid was found in 33 patients. It was stated that quantity of the protozoa and anti-IgM presence in mothers' blood are the factors influencing significantly the Toxoplasma gondii manifestation in amniotic fluid., Conclusion: High suitability of PCR in diagnosis of Toxoplasmosis during pregnancy and vertical transmission was confirmed.
