ABSTRACT
OBJECTIVE: The Arabin pessary may be beneficial in the treatment of cervical incompetence. The aim of the study was to analyse the efficacy of the treatment method of pregnant women with cervical incompetence. METHODS: A non-randomised study performed in the obstetrical wards in Lodz, Poland utilising 54 pregnant women with cervical incompetence was developed to assess the efficiency of treatment methods of cervically incompetent women. These women were diagnosed by vaginal ultrasound examination during the course of the study. Patients with a cervical length of 15-30 mm before 28 weeks an Arabin cervical pessary were inserted, women whose cervical length was less than 15 mm were treated with cervical cerclage. The main end points of the study were preterm or term delivery. RESULTS: In the Arabin pessary group, 1.9% of women delivered before the 29th week of gestation and 83.3% of women delivered after 37 weeks of pregnancy. Eighty-seven per cent of pregnant women treated for cervical incompetence by Arabin pessary delivered by normal spontaneous labour, 1.9% delivered by forceps labour and 11.1% of patients by caesarean section. Among pregnant women treated by Arabin pessary, 3.7% of newborns were estimated as having a score of 0-4 on the Apgar scale, 13% a score of 5-7 and 83.3% a score of 8-10. CONCLUSIONS: Cervical incompetence treatment effectively prolongs the duration of gestation. Application of the Arabin pessary is an effective method of cervical incompetence treatment.

PURPOSE: Different sonographical and biochemical methods for the detection of an elevated risk of chromosomal abnormality are used. The aim of our study was to establish a diagnostic scheme with the highest sensitivity by means of an algorithm incorporating all parameters. MATERIALS AND METHODS: In a group of 1490 pregnant women, ultrasound examination including nuchal translucency and nasal bone measurement was performed in the first trimester. Then, in the early second trimester, a second ultrasound examination combined with measuring nuchal thickness and nasal bone was carried out. RESULTS: The combination of the NT and NB measurement showed the highest sensitivity (94.7%), specificity (99.21%), PPV (85.7%) and NPV (99.73%). CONCLUSION: The proposed integrated test is characterised by a high predictive value for the detection of chromosomal abnormalities, low cost of performance and absolute safety for the foetus and could be offered to all pregnant women. The combination of two ultrasound examinations and biochemistry greatly increased the value of the test.

INTRODUCTION: The objective of the study was to examine the relationship between the concentrations of maternal serum AFP, total beta-hCG and uE3 and the presence of various pathologies of the feto-placental unit. MATERIAL AND METHODS: The triple test was performed in the group of 882 pregnant women between the 14th and 21st week of gestation. The control group consisted of 863 pregnant women with unburdened obstetric anamnesis with an uneventful singleton pregnancy. The examined group consisted of 19 pregnant women with fetal aneuploidies and other pathologies of the feto-placental unit (oligohydramnios, vacuolization of the trophoblast). In the maternal sera concentrations of AFP, total beta-hCG and unconjugated estriol were determined. The risk of fetal trisomy 21 was calculated using DOWNS and PRISCA 3.0 software (cut-off 1: 295), Ulm Index was also calculated (cut-off 8.1). RESULTS: In the group of pregnant women with fetal chromosomal aneuploidies no significant changes of the examined parameters were established. In the cases of oligohydramnios AFP concentrations significantly increased, in the cases of fetal triploidy the concentrations of all examined parameters decreased. In the cases of vacuolization of the trophoblast concentration of the total beta-hCG increased. CONCLUSION: Oligohydramnios, fetal triploidy and vacuolization of the trophoblast caused significant changes of the concentrations AFP, total beta-hCG and unconjugated estriol in maternal sera.

The study comprises 889 pregnant women between 14 and 21 weeks of gestation. The control group consisted of 862 pregnant women with unburdened obstetric anamnesis with an uneventful singleton pregnancy. The examined group consisted of 27 pregnant women with uncomplicated twin pregnancy. In the sera of pregnant women AFP (Microparticle Enzyme Immunoassay AxSYM Abbott), total beta-hCG (Microparticle Enzyme Immunoassay AxSYM Abbott) and unconjugated estriol (Radioimmunoassay Amerlex-M. 2T Johnson & Johnson Ortho Clinical Diagnostics Ltd.) were determined. The risk of fetal trisomy 21 was calculated with the use of PRISCA 3.0 software, which corrected the MoM values for twin pregnancy. Ulm Index was also calculated. In the majority of twin pregnancies increased concentrations of AFP, total beta-hCG and uE3 in the range over 1.0 MoM was noted. In the group of women below 35 years of age with singleton pregnancies using PRISCA 3.0 software it approximated to 95%. For women older than 35 optimum index for fetal trisomy 21 risk calculation was Ulm Index with the specificity 93.8%. The specificity of AFP determination in the detection of fetal open NTD in singleton pregnancy was 99%. In the group of women with twin pregnancy the obtained specificity of 77.8% for PRISCA 3.0 software is low, a more advantageous way to calculate the risk of fetal trisomy 21 is Ulm Index with the specificity of 85.2%. The specificity of AFP determination as a screening for fetal open NTD in twin pregnancy was 96.3%.
