В статье показаны результаты лечение бактериального вагиноза у 40 беременных в I триместре. 25 беременным проводилось комплексное лечение, включающее применение вагинальных свечей с действущим веществом хлоргексидин, по 1 свече на ночь во влагалище в течение 10 дней в сочетании с пероральным применением Флориум по 1 капсуле х 2 раза в день за 30 минут до еды в течение 14 дней. Остальные 15 беременных получали только свечи с действующим веществом хлоргексидин местно по 1 свече на ночь во влагалище в течение 10 дней. Сравнительный анализ результатов лечения показал, что в группе лечения с применением комплекса лактобактерий у 100% беременных «ключевые клетки» в контрольном мазке после лечения не определялись, в то время как у 16% женщин контрольной группы в мазке после лечения всё ещё определялись «ключевые клетки». А также, беременные основной группы отмечали прекращение жидких выделений с неприятным запахом в 100% случаев, в то время как у 23% беременных контрольной группы продолжались такие выделения, причиняющие дискомфорт. The article shows the results of treatment of bacterial vaginosis in 40 pregnant women in the first trimester. 25 pregnant women underwent complex treatment, including the use of vaginal candles with the active substance chlorhexidine, 1 candle per night in the vagina for 10 days in combination with oral administration of Florium 1 capsule x 2 times a day 30 minutes before meals for 14 days. The remaining 15 pregnant women received only candles with the active substance chlorhexidine locally, 1 candle per night in the vagina for 10 days. A comparative analysis of the results of treatment showed that in the group of treatment with the use of lactobacilli complex in 100% of pregnant women, " key cells "were not determined in the control smear after treatment, while in 16% of women of the control group,"key cells" were still determined in the smear after treatment. And also, pregnant women of the main group noted the cessation of liquid secretions with an unpleasant smell in 100% of cases, while 23% of pregnant women of the control group continued such secretions causing discomfort.

Hypothesis/aims of study. The problem of vaginal infections during pregnancy is of high importance in obstetric practice. To predict the risks and reduce the frequency of pregnancy and childbirth complications, it is necessary to dynamically assess the vaginal microflora and treat its disorders. The aim of the study was to investigate the vaginal microflora and evaluate the effectiveness of treating vaginal infections in pregnant women with a history of miscarriage. Study design, materials and methods. The study included 153 pregnant women in the first trimester. The main group (group I) consisted of 99 women with a history of miscarriage, 35 of whom had signs of threatened abortion (subgroup IA) and 64 did not (subgroup IB). The control group (group II) comprised 54 women without a history of miscarriage and signs of threatened abortion. The vaginal microflora was examined using microscopic, bacteriological and quantitative real-time PCR methods. All patients with an established vaginal infection (bacterial vaginosis, aerobic vaginitis, and vulvovaginal candidiasis) received etiotropic therapy, depending on the microorganisms identified and their sensitivity to antimicrobial drugs. After treatment, in order to assess the effectiveness of the therapy, the vaginal microflora was examined in the second trimester and the outcomes and complications of present pregnancy were evaluated. Results. In women of subgroup IA, vulvovaginitis and bacterial vaginosis were detected 3.5 times more often compared to the control group, and 1.6 times more often compared to subgroup IB (66% and 19%, respectively, p 0.001; 66% and 42%, respectively, p 0.05). Aerobic vaginitis was the most frequent vaginal infection in the first trimester of pregnancy in women of the main group (p 0.05). After treatment, the frequency of the vaginal infections in the second trimester in women of the main group significantly decreased: by 1.9 times in subgroup IA and by 1.5 times in subgroup IB (p 0.05). There were no significant differences in the frequency of adverse pregnancy outcomes in women with bacterial vaginosis or vulvovaginitis as compared to women with normal vaginal microflora. Nevertheless, pregnancy and childbirth complications were diagnosed 4 times more frequently in the main group (23% and 6%, respectively, p 0.05), with the complications occurring significantly more often in the cases of vulvovaginitis or bacterial vaginosis and signs of threatened abortion in the first trimester (p 0.05). Conclusion. Etiotropic therapy of vaginal infections diagnosed in the first trimester of pregnancy in women with a history of miscarriage was highly effective. In 40% of women, vaginal microbiocenosis normalized, and the clinical symptoms of vaginosis/vaginitis disappeared. Differences in the frequency of adverse pregnancy outcomes in women with vulvovaginitis or bacterial vaginosis in the first trimester and in women with normal vaginal microbiocenosis were not significant. However, the treatment of vaginal infections in the group of pregnant women with a history of miscarriage did not significantly affect the frequency of pregnancy and childbirth complications.

The objective: frequency decrease perinatal pathologies at women after ART on the basis of studying clinical-ehografical, endocrinological, biochemical, dopplerometrical, cardiotokografical and morphological researches, and also improvement of algorithm of diagnostic and treatment-and-prophylactic actions. Patients and methods. The work basis is made spent by us from 2012 on 2015 by complex inspection of 300 pregnant women from which 250 were after ART and 50 – firstlabours which pragnency without ART, and also their newborns. For the decision of an object in view of research spent to two stages. At 1 stage spent prosperctive research which included 150 pregnant women: з them 100 women pregnancy at which has come out ART (1 group) and 50 healthy women (control group). At 2 stage spent prospective randomization in which result of patients after ART have divided on two equal groups by therapy principle: 2 basic group - 75 pregnant women after ART at which used the algorithm improved by us; 3 group of comparison - 75 pregnant women after ART which have been spent on the standard treatment-and-prophylactic actions. Results. The results suggest that women after using ART is a high frequency of reproductive losses in the first trimester (10.0%), 3.0% of spontaneous abortion from 16 to 22 weeks, and 3.0% "early" premature delivery (22 to 28 weeks of pregnancy). The frequency of violations of the functional state of placenta in women after using IVF is 63.0%, which is the main cause of high levels of perinatal losses (40.0 ‰), and delivery by cesarean section (96.0%). Placental dysfunction in women after using ART characterized by retrohorialnyh hematoma (21.0%); size mismatch fruit (30.0%) and hypertonicity of the uterus (73.0%) against changes in fruit-placental blood flow - increased resistance index in umbilical artery and increased vascular resistance in the uterine arteries. Endocrinological and biochemical changes in placental dysfunction in women after using IVF starting from 28 weeks of pregnancy and are in significant reduction in progesterone, placental b1-microglobulin, B2-microglobulin of fertility and trophic в-glycoprotein. Conclusion. The received results: use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows to lower frequency of spontaneous interruption of pregnancy till 22 weeks – from 13.0% to 5.7%; «early» premature birth – from 3.0% to 1.0%; placentary dysfunction from 63.0% to 40.6%; cesarean sections – from 96.0% to 56.5%, and also perinatal losses – from 40.0‰ to 16.2‰. Key words: pregnancy, childbirth, auxiliary reproductive technologies.

Objective: Spontaneous abortion is the most common complication of early pregnancy, affecting up to 20% of recognized pregnancies. Kisspeptin is predominantly released by placental syncytiotrophoblasts, and regulates their placental invasion into the uterine matrices. We aimed to establish an association of serum kisspeptin levels with pregnancy outcomes during the early gestational stage of the first trimester. Method: In this prospective study, 90 pregnant women in their 7 to 8 6/7 gestational weeks were classified into three groups: (i) The control group, consisting of healthy pregnant women (n=30), (ii) the threatened abortion group (n=30), and (iii) the spontaneous abortion group (n=30). The maternal serum samples were analyzed for complete blood count parameters and kisspeptin levels. Results: There was no statistical difference regarding body mass index (BMI) and gestational age (p=0.370). Regarding detailed obstetric notations, including gravida, parity, abortion, and living children, socioeconomic levels, and employment rates, all study groups were comparable (p>0.05, for all). No significant association was found regarding the biochemical parameters of complete blood count, including neutrophil, lymphocyte, and platelet concentrations, as well as neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) (p>0.05, for all). The median serum kisspeptin levels of the study groups did not differ between the groups (p=0.153). Correlation analysis revealed no significant relationship between serum kisspeptin levels and other study parameters in any study groups (p>0.05, for all) Conclusions: We found no statistically significant relationship between serum kisspeptin concentrations and pregnancy outcomes in the early gestational stage of the first trimester, and serum kisspeptin concentrations did not seem to be a reliable marker to distinguish abortion status from viable pregnancy

BACKGROUND: The prevalence of anemic pregnant women is still reasonably high, especially in low-middleincome countries. AIM: This study was aimed to assess the effect of giving red seaweed (Kappaphycus alvarezii) biscuits on changes in hemoglobin (Hb) levels and body weight of pregnant women in the first trimester. METHODS: The study used a quasi-experiment pretest-posttest study design. The study was conducted from April to June 2021 involving pregnant women in the first trimester who living in the working area of the Wapunto Community Health Center, Muna Regency, Indonesia. A total of 45 pregnant women were selected purposively and assigned to three different groups. The first group was given two pieces of red seaweed biscuits per day. The second group was given two pieces of red seaweed biscuits plus Fe tablets (60 mg/day), and the last group was given Fe tablet only (60 mg/day). Chi-square, paired sample t-test, Wilcoxon, and Kruskal–Wallis tests were performed using SPSS. RESULTS: The intervention group of red seaweed biscuits plus Fe tablets had the highest increase in Hb levels after 8 weeks of intervention, followed by the red seaweed biscuit group and the control group (0.97, 0.78, and 0.60 g/dL, respectively, p-value < 0.05). The red seaweed biscuit intervention group had the highest changes for body weight compared to the red seaweed biscuit plus Fe tablet group and the control group (1.07, 0.43, and 0.04 kg, respectively). CONCLUSION: The provision of red seaweed biscuits could increase maternal Hb level and weight during the first trimester of their pregnancy.

Summary: Introduction: Preeclampsia is a life-threatening condition for the mother and foetus. Globally, it is diagnosed in 10 mil. women every year, which accounts for 3% to 8% of all pregnancies. Currently there is no proven effective treatment for preeclampsia. The aforesaid text actualises the issue of predicting this complication. To determine the prognostic significance of matrix metalloproteinases-2 and -9 levels as early markers of preeclampsia, the present prospective study was conducted. Materials and methods: The levels of matrix metalloproteinases-2  and -9  were assessed in 72  patients. Thirty-four  of them subsequently developed preeclampsia during pregnancy (20 patients with moderate preeclampsia, 14 patients with severe preeclampsia), and constituted the basic group; 38 patients made up the control group. Results: In pregnant women with the subsequent development of preeclampsia, the level of matrix metalloproteinase-2 at 11–13 weeks of gestation was 155 ± 73.4 ng/mL and significantly exceeded its level in pregnant women without hypertensive disorders – 75.0 ± 32.8 ng/mL. The study conducted demonstrates a significantly lower concentration of matrix metalloproteinase-9 in pregnant women with preeclampsia compared to the control – 749 ± 296 ng/mL and 1,667 ± 552 ng/mL (P < 0.001). The performed research figures that in the first trimester, the cut-off value of matrix metalloproteinase-2 for predicting the development of preeclampsia is ≥ 102 ng/mL (sensitivity 88.24% and specificity 82.76%). For matrix metalloproteinase-9, a level of ≤ 980 ng/mL in the first trimester predicts the development of preeclampsia with a sensitivity of 85.29% and a specificity of 84.48%. Conclusion: The study established the cut-off values of matrix metalloproteinases-2 and -9 for predicting the development of preeclampsia in the first trimester.

The aim: The purpose of research is to improve the effectiveness of treatment by applying laser in complex treatment in patients with herpetic stomatitis. Materials and methods: Were examined 47 people (22 men and 25 women) with acute herpetic stomatitis. The patіents’ age was from 20 to 72 years. All patients underwent immunological tests such as (T-lymphocytes (CD3 +), T-helpers (CD4 +), cytotoxic T-lymphocytes (CD8 +), the content of immunoglobulins IgM, IgG, IgA and slgA in saliva to assess the іmmunological reactivity of the organism. Results: Clinical observations have shown that when using laser therapy, the results of treatment were better than in the control group. Positive dynamics was observed as early as 1-2 days after the start of laser use and was more pronounced when used in the early stages of the disease. The use of the laser promoted a more rapid suspension of new lesions, a decrease in pain syndrome, and a more rapid regression of herpetic lesions. We have found significant improvements in the arameters of cellular and humoral іmmunity in patients of the main group. Conclusions: Treatment of herpetic stomatitis is relevant and requires further improvement and the search for new methods. The use of a laser in the complex treatment of herpetic stomatitis has a positive effect on the course and іmmunological status of patients with herpetic stomatіtis. The manifestations of the disease healed faster, and the pain syndrome was less severe. Duration between іllness and treatment decreased on 19.7% and 26%. It is advіsable to include the method of treatment using a laser in the complex therapy of herpetic stomatitis.

As part of the population-based prenatal screening of 900 pregnant women, who underwent 1st trimester screening at the RPMC “Mother and Child” in 2018–2019, an ultrasound scan of the fetal palate was performed to evaluate the effectiveness of new ultrasound markers in detecting orofacial clefts (OFC). Fetal palatal defects were screened at a 2D assessment of bone markers of the palate – the image of the palatal line in the sagittal section, the retronasal triangle in the coronary section, the alveolar arch of the upper jaw in the axial section. If a palate abnormality was detected or suspected in the 2D study, the fetal palate was evaluated using the 3D mode. In 50 pregnant women of the control group, 3D sonography of the fetal palate was performed in the norm. In total, during the gestation period of 10+5–12+5 weeks, 10 cases of OFC were detected, of which 1 case was a median lip/palate cleft (LPC), 6 — bilateral LPC, 1 — left-sided LPC, 1 — unspecified LPC, 1 — PC. Visualization of 2D ultrasound markers was possible in 9 cases of palate anomalies, 3D assessment worked out in all 10 cases. In all identified OFC cases, cytogenetic and/or pathomorphological studies were performed.

Objective: To measure the distribution of TPO-Ab positivity and to observe the effect of thyroid peroxidase positivity on thyroid function during first trimester in normal pregnancy. Method: A cross sectional among 120 subjects were taken in this study and divided into control and study groups. Control group (Group A) consisted of 60 healthy non pregnant women age ranged between 20 to 35 years. Study group (Group B) consisted of 60 normal pregnant women of same age range. Group B was further subdivided into group B1 and group B2according to the level of TPO-Ab. Group B1 consisted of TPO-Ab positive pregnant women and group B2 consisted of TPO- Ab negative pregnant women. Control group was selected from personal contacts and study group from Out Patient Department (OPD) of Obstetrics and Gynecology of Sir Salimullah Medical College and Mitford Hospital. For assessment of thyroid function, serum free thyroxine (FT4), thyroid stimulating hormone (TSH) were measured. Serum FT4, TSH were measured by Enzyme link immunosorbant (ELISA) method. Again, serum TPO-Ab of total study population and hCG of all the pregnant women were measured. Serum TPO-Ab by Micro particle Enzyme Immunoassay (MEIA) method and hCG was estimated by ELISA. Statistical analysis was done by SPSS version 17. Results: In this study, serum FT4 and was significantly (P<0.001) higher and TSH level was significantly (P<0.001) lower in normal pregnant women during 1st trimester in comparison to those of non pregnant women. Again, 18% of pregnant women showed TPO-Ab positivity. However, serum FT4 level was significantly (P<0.001) lower whereas, TSH level was significantly (p<0.001) higher in TPO-Ab positive pregnant women in comparison to those of TPO-Ab negative pregnant women. Conclusion: TPO-Ab positivity increases during 1st trimester of normal pregnancy which decreases the hyper functional state of thyroid hormones. So, thyroid screening should be done routinely during pregnancy. DOI: http://dx.doi.org/10.3329/updcj.v4i1.21160 Update Dent. Coll. j: 2014; 4 (1): 15-20

Aim. To study capabilities of quantitative elastographic study to assess the elasticity of the uterine cervix in women with a fetal chromosomal abnormality in the first trimester of pregnancy.Methods. 230 pregnant women of high-risk group at 11-13.6 weeks of pregnancy (parietal-coccygeal length 45-84 mm) were included in this study. The first group consisted of 213 women without fetal pathology. The second group included 17 women, in whose fetuses different chromosomal abnormalities were detected. In ultrasound examination of pregnant women in the I trimester of pregnancy, in addition to standard methods of examination, quantitative cervical elastography was performed.Results. According to results of quantitative elastography in 14 (82.35%) out of 17 pregnant women (second group) one or another degree of the cervical tissue softening was found, and 3 (17.64%) pregnant women with fetal chromosomal pathology had stiff cervix (all 3 cases with Down syndrome). In the control group in 10 (4.7%) of 213 pregnant women relatively soft cervix was identified, and in 203 (95.3%) women cervical density was higher than the myometrial density. A statistically significant difference between the indices of SWE-Ratio in groups was revealed. Quantitative elastography, as a diagnostic test predicting the risk of miscarriage due to chromosomal abnormalities, has a high sensitivity (84.38%) and even higher specificity (95.26%) of negative predictive value 97.57%.Conclusion. Quantitative elastography reveals a significant decrease in the cervical elasticity (softening) in pregnant women with fetal chromosomal abnormality in the I trimester of pregnancy, which allows us to recommend this method of ultrasound examination as an additional marker for early diagnosis of miscarriage due to fetal chromosomal abnormality.

The aim of the work is to assess the effects of cytomegalovirus infection on the 20α-hydroxysteroid dehydrogenase activity in the villous chorion syncytiotrophoblast in the first trimester of pregnancy. The materials for the study included 48 villous chorions samples taken during spontaneous abortions at 8th–10th weeks of gestation from women with reactivation of cytomegalovirus infection (the main group). The control group included 35 villous chorions samples from pregnant women with chronic cytomegalovirus infection in the latent stage taken at medical abortions at the same stage of gestation. The results of women’s examination were studied taken into account the activity of cytomegalovirus infection by immunoassay by detection of IgM antibodies or by 4 times and more increase of IgG antibody titers in the paired serums in dynamics in 10 days. The activity of 20α-hydroxysteroid dehydrogenase was assessed by the histochemical method. Quantitative evaluation of the reaction products was carried out on sections under the microscope MT (Japan) connected to software-hardware complex «SCION Corporation» (USA). At histochemical specimen of villous chorion of pregnant women who had a reactivation of cytomegalovirus infection during pregnancy (main group), there was a decrease of cytophotometric parameter of 20α-hydroxysteroid dehydrogenase activity till 30.1±2.12 pixels/μm2 (p<0.001) compared with the control group. The decrease in the reaction activity in syncytiotrophoblast indicated a decrease in the contents of 20α-dihydroprogesterone in placenta, which contributed, in our opinion, to spontaneous abortion.
