Live birth of monochorionic triamniotic triplets after in vitro fertilization and blastocyst transfer: case report and review of the literature.

Unlabelled: Monozygotic triplet pregnancies are very rare, even after in vitro fertilization (IVF). We present a case of a live birth of triplets from a monochorionic triamniotic pregnancy after blastocyst transfer. A 29-year-old woman underwent intracytoplasmic sperm injection (IVF-ICSI).

[Prognostic value of chosen parameters of mechanical and bioelectrical uterine activity in prediction of threatening preterm labour].

Objectives: To record and analyse bioelectrical activity of the uterine muscle in the course of physiological pregnancy, labour and threatening premature labour; to define which parameters from the analysis of both electrohysterogram and mechanical activity signal allow us to predict threatening premature labour.

Material And Methods: Material comprised 62 pregnant women: Group I--27 patients in their first physiological pregnancy, Group II--21 patients in their first pregnancy with symptoms of threatening premature labour, and Group III--14 patients in the first labour period. The on-line analysis of the mechanical (TOCO) and electrical (EHG) contraction activity relied on determination of quantitative parameters of detected uterine contractions.

[Mechanical and electrical uterine activity. Part II. Contractions parameters].

Frequency and strength of the uterine contractions monitoring enables to control the labour progress and also, although in a restricted way, to determine the beginning of labour, as long as it is not preterm. Mechanical approach provides only the low frequency signal, which describes the contractions more or less accurately, depending on whether an intrauterine pressure measurement is used in the former case or whether an external stress measurement is applied in the latter case. This signal does not comprise information on contractions characteristics and enables only to estimate their basic timing parameters.

[Mechanical and electrical uterine activity. Part I. Contractions monitoring].

Correct uterine contraction activity during labour determines physiological fetal delivery and ensures its satisfactory outcome. Contraction activity monitoring may be accomplished by either recording of the mechanical properties of the uterine muscle and/or by measurement of the action potentials produced by the uterus during contraction. In the following paper, the current state of knowledge concerning the methods for assessment and monitoring of the uterine contraction activity was evaluated.

Homocysteine serum concentration and uterine artery color Doppler examination in cases of recurrent miscarriages with unexplained etiology.

Objectives: To study the assessment of diagnostic value and clinical usefulness of the determination of homocysteine concentration in blood serum in cases of recurrent miscarriages and the relation between the concentration of homocysteine in blood serum and parameter values determining the Doppler blood flow in the uterine arteries.

Methods: Homocysteine concentration in blood serum was determined in a group of 30 women with at least two subsequent miscarriages with no clear reason and in the control group consisted of 20 non-pregnant women without a medical history of obstetric failures, having at least one healthy child. In all cases Color Doppler sonography was performed to determine flow velocity waveforms of the uterine arteries in luteal phase of the menstrual cycle.

Homocysteine, folic acid and vitamin B12 concentration in patients with recurrent miscarriages.

Objectives: The aim of the project was the assessment of clinical usefulness of the determination of blood serum homocysteine concentration, folic acid and vitamin B12 in recurrent miscarriages.

Methods: 30 non-pregnant women with recurrent miscarriages (examined group-I) and for 20 non-pregnant women without obstetric failures in medical history (control group-II) were examined.

Results: In the examined group (group I), the average concentration of homocysteine (9,45 micromol/l) was not statistically higher in comparison to the control group (group II) (8,47 micromol/l) (p>0,05).
