AbstractThis paper summarizes our experience with Doppler velocimetry in survivors of intrauterine co-twin demise. In the first trimester, ten dichorionic deaths occurred; none of the survivors developed flow disorders. During the second trimester, there were three intrauterine demises, two of them were monochorionic and the survivors developed flow disorders: one presented transitory venous flow aberration, the other one an impaired development of diastolic flow. In the third trimester, two intrauterine deaths occurred. One case of twin to twin transfusion syndrome (TTTS) was complicated by the donor's death and the recipient showed a loss of diastolic flow. The second one happened during a dichorionic twin pregnancy. The survivor presented high systolic/diastolic daily ratio (S/D = 7.8).

And Control

Currently, pediatricians, neonatologists of maternity hospitals often take part in perinatal consultations. One of the indications for early delivery may be chronic placental insufficiency diagnosed during an ultrasound examination. Objective: to evaluate the effectiveness of the main method of diagnosis of placental insufficiency at the present time – ultrasound evaluation of the placenta. Materials and methods. An analysis was made of 357 birth histories, exchange cards, protocols for screening ultrasound in the third trimester of pregnancy and conclusions of pathoanatomical investigation. Results. To substantiate the need for prenatal diagnosis of chronic kidney disease, a comparison was made of the evaluation of newborn babies on the Apgar scale and the state of the placenta according to histological data. With compensated chronic placental insufficiency, there was no difference in Apgar scores at the first and fifth minutes, whereas in the subcompensated stage, Apgar score on the Apgar scale was significantly lower in the first and fifth minutes than in the control group. To identify possible in practical use of the objective parameters of diagnosis of chronic kidney disease, the thickness of the placenta was measured during the screening ultrasound in the third trimester of pregnancy, as well as the thickness of the placenta after its separation. Significant differences in the thickness of the placenta or in the screening ultrasound, or when measuring the placenta after separation in patients with and without chronic placental insufficiency was not detected. When assessing a violation of the rate of maturation of the placenta in the third trimester of pregnancy, no significant differences were found in the presence and absence of placental insufficiency. An analysis of the amniotic index was carried out to determine the amount of amniotic fluid in patients of the main and control groups, which revealed no significant differences between the groups. Conclusions. The authors believe that the main indicators currently used for diagnosis of chronic placental insufficiency (thickness of the placenta, degree of maturity of the placenta, appearance of structural changes in the placenta, change in the amount of amniotic fluid) are uninformative and modern placenography does more harm than benefit. The only parameter determined during the screening study in the third trimester of pregnancy and having significant differences in the main and control groups is fetal hypotrophy.

To assess the role of cholesterol and estradiol in the development of placental insufficiency under cytomegalovirus infection (CMVI) in the period of gestation, cholesterol and estradiol were studied in the peripheral blood of 35 pregnant women who had a reactivation of chronic CMVI (IgG antibody titer to CMV is 1:1600) in the third trimester of pregnancy (the main group). As a control the blood plasma of 35 healthy women of the same period of gestation and age as in the main group were studied. It was found out that the reactivation of chronic CMVI in the third trimester of gestation was followed by the decrease of concentration of cholesterol by 23% ( p<0.001), of estradiol by 65% (p<0.001) in comparison with the values of healthy women. To analyze the chosen values for assessment, the discriminant function was found. It had the probability of differences not less than 95%; which that the discriminant equation was derived which for this study had the following formula: D=(-379×total cholesterol)+(-0.072×estradiol), where D is a discriminant function whose limit value is (-2673.59). If D is equal or less than the limit value, then the development of placental insufficiency in women in the third trimester of pregnancy is predicted, and if D is more than the limit value, then the normal course of the third trimester of pregnancy is predicted. Thus, the obtained results allow to establish the main role of disturbances of total cholesterol contents and key steroid hormone of pregnancy (estradiol) in the pathogenesis of placental insufficiency development under CMVI during gestation, which can be the basis for improvement of diagnostic and medical basis under this pathology of pregnant women.

Abstract Background and aims: Gestational diabetes represents a form of diabetes diagnosed during pregnancy that is not clearly overt diabetes. In the last trimester of gestation the growth of fetoplacental unit takes place, thus maternal hyperglycemia will determine an increased transplacental passage, hyperinsulinemia and fetal macrosomia. The aim of our study was that o analyzing the effect of maternal glycemia from the last trimester of pregnancy over fetal weight. Material and method: We run an observational study on a group of 46 pregnant women taken into evidence from the first trimester of pregnancy, separated in two groups according to blood glucose determined in the third trimester (before birth): group I normoglycemic and group II with hyperglycemia (>92mg/dl). Results: The mean value of third trimester glycemia for the entire group was of 87.13±22.03. The mean value of the glycemia determined in the third trimester of pregnancy was higher in the second group (109.17 mg/dl) in comparison to the first group (74.,21 mg/dl). The ROC curve for third trimester glycemia as fetal macrosomia appreciation test has an AUC of 0.517. Conclusions: Glycemia determined in the last trimester of pregnancy cannot be used alone as the predictive factor for fetal macrosomia.
