Objectives: The presence of the uterine leiomyomas may change the concentrations of the screening serum markers and so after the risk calculation of the fetal chromosomal abnormalities.

Purpose: To estimate the influence of the uterine leiomyomas on the first and second trimester serum markers concentrations.

Material And Methods: The studied group consisted of 127 women between 11 and 20 weeks of normal singleton pregnancy.

Objectives: PIH and IUGR are serious complications in the third trimester of pregnancy. Many publications claim a connection between false positive prenatal tests and subsequent occurrence of PIH and IUGR.

Design: The aim of the study was to estimate the usefulness of the biochemical markers of fetal defects and uterine Doppler examination in predicting PIH and IUGR in the third trimester of pregnancy.

Modern, non-invasive prenatal diagnostics based on biochemical and ultrasonographic markers of fetal defects allows us to calculate the risk of fetal chromosomal aneuploidies with high sensitivity and specificity An introduction of biochemical, non-invasive prenatal tests turned out to result in frequent false positive results of these tests in cases when invasive diagnostics does not confirm fetal defects. However prospective analysis of these cases showed numerous complications in the third trimester of the pregnancies.

Unlabelled: Cardiac defects, the most common forms of congenital defects, are found in 3-8 of every 1000 pregnancies. Currently only 15-30% of CHD in newborns is detected prenatally. There are different strategies to increase the prenatal detection of cardiac abnormalities.

Objectives: Uterine myomas may change the concentrations of the screening serum markers and therefore alter the risk calculation of the fetal chromosomal abnormalities. An increased risk leads to invasive diagnostics procedures which in these cases can often be technically difficult due to the presence of myomas.

Aim: The aim of this study was to assess the influence of uterine myomas on the first and second trimester serum markers concentrations and, possibly on the test results.

The Aim Of Study: Estimation of Polish population standards of the concentrations of pregnancy-associated plasma protein--A (PAPP-A) and free beta--human chorionic gonadotropin (beta-HCG) in the maternal blood between 10.0 and 13.6 week of pregnancy and comparison of the biochemistry own normal ranges and literature reported data.

Thrombotic thrombocytopenic purpura (TTP) is characterized by microangiopathic hemolytic anemia and thrombocytopenia, accompanied by microvascular thrombosis that causes variable degrees of tissue ischemia and infarction. About 10-20% of TTP cases are associated with the pregnancy. Preterm delivery and intrauterine fetal death are frequent pregnancy complications of TTP.

Unlabelled: Second-trimester maternal serum markers (triple test) is common used to estimate of the fetal risk of genetic abnormalities and open neural tube defects. Positive results of the triple test concomitant with the normal fetus karyotype pattern can also predict the adverse pregnancy outcome. Many authors have been indicated such false positive results of the triple test in the cases of the uterine myomas, PIH, IUGR, and IUD.

Objectives: Dynamic development of prenatal diagnostics is mostly directed towards search for non-invasive screening. The main role of the screening methods is to select high-risk fetal aneuploidy group of pregnant women. The base for the prenatal screening in modern obstetrics is ultrasound scanning.

Unlabelled: In the case of positive triple test results the presence or absence of sonographic markers is associated not only with fetal abnormalities, but also with a variety of adverse outcomes of pregnancy.

Objective: Evaluation of sonographic markers of chromosomal abnormalities in verification of positive results of triple tests.

Material And Methods: In consecutive series of 780 pregnant women we performed triple tests at 14-19 weeks.

The aim of the study was to develop an early ultrasound diagnostic schema for the determination of increased risk for fetal chromosomal aneuploidies. The study was conducted on a population of 1318 pregnant women divided into 2 groups: 1255 women with the normal course of pregnancy and 63 women with diagnosed fetal abnormalities. There were 34 cases of chromosomal abnormalities (trisomy 21, 18, 13; triploidy; unbalanced inversion 9; deletion 16) and 29 cases of structural malformations.

The HLA complex, located on the short arm of chromosome 6, is the strongest genetic marker for type 1 diabetes (T1DM). In previous study we demonstrated association between genes HLA-DRB1 and HLA-DQB1 and T1DM in the Polish population. There is a strong-independent association of alleles HLA-DRB1*0401 and DQB1*302, despite population linkage disequilibrium among alleles of these genes.

Unlabelled: Severe hypoglycemia may limit the effects of type 1 diabetes treatment. Insulin antibodies were mentioned to be included in the pathogenesis of hypoglycemia in adult diabetic patients, particularly those treated with non-human insulins. The influence of insulin antibodies on the occurrence of hypoglycemia in children treated with human insulin was not studied.

Background: In some patients the ketoacidosis at the onset of type 1 diabetes has been observed.

Aim: The aim of this study was to investigate an effect of the clinical, genetic, immunological and metabolic parameters on the occurrence of ketoacidosis at the clinical onset of the disease.

Material And Methods: 106 children with type 1 diabetes, aged 1.
