The article is devoted to the current methods of diagnostics of the dental system of a pregnant womans fetus. The use of three-dimensional ultrasonography in pregnant women based on prenatal ultrasound screening opens up new opportunities for preventing serious maxillofacial deformities. The results of our own research allowed us to establish the links and quantitative dependencies for identifying malocclusion risk groups. Literature data on the use of fetal ultrasound diagnostics to assess the state of the fetal dental system are analyzed.

Research objective: to evaluate the effectiveness of diagnosis and complex therapy of placental dysfunction (PD) in early stages of gestation.Materials and methods. We examined 110 pregnant women with risk for the primary PD. Exclusion criteria were multiple pregnancies, anomalies of fetal development and internal genital organs of the mother, pregnancy resulting from assisted reproductive technologies.The diagnosis of PD was established in 56 women (group I) based on the assessing the state of extraembryonic structures and blood flow in the spiral and uterine arteries at 12–13 weeks of gestation. The rest of the patients (54 women) entered the control group without PD (group II).Results. All pregnant women with verified PD at 12–13 weeks were prescribed complex drug treatment, which included micronized progesterone, venotonic Normoven, Magnicum, and Artihol. As a result of treatment, already at 22–24 weeks of gestation, the average value of blood flow (resistance index) in the uterine and spiral arteries did not differ significantly in the groups. There was no significant difference in fetometry and placentometry indices at 35–36 weeks of gestation. Complications of the gestational period in patients in the study groups were also almost the same.Conclusions. History of hormonal disorders and miscarriage, clinical signs of miscarriage in early gestation, abnormal embryo placement, extragenital pathology, and genital tract infections are risk factors for PD. Determination of the state of extraembryonic structures at 7–8 weeks of pregnancy (ovum volume, blood flow in the corpus luteum) and at 12–13 weeks (chorion volume, vascularization index, blood flow in the spiral and uterine arteries) can serve as a verification criterion for the PD development. Complex drug therapy, which began from the early stages of gestation (micronized progesterone, Normoven, Magnicum, Artihol) has established itself as an effective method of treating primary PD in pregnant of risk groups.

Background. Serious perinatal, most of all, neurological consequences of placental insufficiency condition necessity further search it’s markers for optimal delivery time. Methods. At third term of pregnancy we examined 16 singleton physiological pregnant women (first group) and 27 placental insufficiency patients (second group). We standard obstetrical examined, ultrasound fetometry, basic arteries of functional system mother-placenta-fetus Doppler and three-dimensional power Doppler in central, two paracentral and two periphery placenta areas. We processing images by VOCAL and analyzed vascularisation (VI), flow (FI) and vascularisation-flow indexes (VFI). Results. In placentae correlated groups FI differ in size reliable in central (t=4,03; p<0,001 и U=240,00; p<0,001) and paracentral (t=2,61; p<0,05 и U=348,00; p<0,05) areas. Patients second group indexes were relative on 17% and 8% less than patients first group indexes. Patients second group VFI was on 35% less than patients first group VFI (t=2,08; p<0,05 и U=337,00; p<0,05). We described results of comparison three-dimensional power Doppler intraplacental blood flow indexes from patients second group with different degree hemodynamic disorder. Conclusion. In placental insufficiency presence reduction blood circulation, particular in central placenta area, conditioned by reduction blood flow in initial vessels number. Central placenta area FI may be regarded new additional criterion of placental insufficiency at third term of pregnancy.

Vitamin A levels during pregnancy have important influences on the health of pregnant women and the growing fetus. Therefore, plasma vitamin A and β-carotene concentrations during pregnancy in Turkish women living in Gaziantep city were investigated in a prevalence study. Optimum sample size was determined as 252 for vitamin A deficiency and vitamin A and β-carotene levels were examined in 427 pregnant women aged 14–44 years. Vitamin A and β-carotene concentrations were measured spectrophotometrically by Neeld Pearson method. Vitamin A and β-carotene concentrations in pregnant women were found as 1.14 ± 0.44 μmol/L, and 1.80 ± 0.66 μmol/L, respectively. Plasma vitamin A concentrations were found in low levels (<1.05 μmol/L) in 45.5 % of pregnant women. Vitamin A deficiency (<0.7 μmol/L) was determined in 16.9% of pregnant women. A mild negative correlation was obtained between the vitamin A concentration and pregnancy period. Vitamin A levels of pregnant women were decreased significantly in the third trimester (p<0.05). The findings of present study suggest that vitamin A levels of pregnant women were poor in the region. Therefore, the intake of vitamin A with foods should be improved. Supplementation of vitamin A might benefit at improving maternal and child health especially in high-risk groups especially in developing countries. Monitoring vitamin A levels in pregnant women is very important for also determining low and high levels.

Background. Congenital dislocation of the knee (CDK) is a rare abnormality of the musculoskeletal system, with an incidence of 1 per 100,000 liveborn infants. Timely prenatal diagnostics and treatment during the initial days of life can help avoid the development of disabilities in a child. Aim of the study. We aimed to study the possible prenatal ultrasound diagnostics and to assess the efficacy of early orthopedic alignment using conservative methods of treatment. Materials and methods. From January 1988 to February 2016, 37 newborns (50 lower limbs) with CDK were treated. The initial assessment of the affected limbs was performed immediately after birth. To determine the severity of dislocation, the Seringe and Tarek classifications were used. Conservative treatment was performed for all the patients. The age of pediatric patients at the time of treatment onset ranged from 2 hours to 5 days. Various methods were used, such as stage plaster bandages (10 lower limbs) and correction using the von Rosen splint (8 lower limbs). Since 2003, a single treatment protocol, developed by the authors of this study, has been applied. Results. The prenatal ultrasound screening enabled the detection of CDK before birth in 21% of cases. Long-term results (catamnesis from 3 to 28 years) were evaluated by the Seringe scale and were excellent in 60%, good in 32%, and satisfactory in 8% of cases. Bad results were not registered. All the pediatric patients included in the study began to walk independently at the age of 9–18 months. Conclusion. Prenatal ultrasound diagnosis enables the detection of CDK. Treatment of newborns, started in the first hours of life, according to the protocol developed by the authors, enables the alignment of the dislocated lower leg in a short time, without using prolonged stage plaster bandages. Long-term results demonstrate the efficiency of the proposed methodology.

Vision is the science that informs us about the biological and evolutionary algorithms that our eyes, opticnerves and brains have chosen over time to see. This article is an attempt to solve the problem of colour to grey conversion, by borrowing ideas from vision science. We introduce an algorithm that measures contrast along the opponent colour directions and use the results to combine a three dimensional colour space into a grey. The results indicate that the proposed algorithm competes with the state of art algorithms.

In the review we have integrated all up-to-date knowledge concerning clinical course and treatment of glaucoma among pregnant women to help specialists choose a proper policy of treatment for such a complicated group of patients. Glaucoma is a chronic progressive disease. It rarely occurs among childbearing aged women. Nevertheless the probability to manage pregnant patients having glaucoma has been recently increasing. The situation is complicated by the fact that there are no recommendations on how to treat glaucoma among pregnant women. As we know, eye pressure is progressively going down from the first to the third trimester, so we often have to correct hypotensive therapy. Besides, it is necessary to take into account the effect of applied medicines on mother health and evaluate possible teratogenic complications for a fetus. The only medicine against glaucoma which belongs to category B according to FDA classification is brimonidine. Medicines of the other groups should be prescribed with care. Laser treatment or surgery may also be a relevant decision when monitoring patients who are planning pregnancy or just bearing a child. Such treatment should be also accompanied by medicines.
