Hypothesis/aims of study. Dysbiotic disorders of the vagina are one of the main risk factors of miscarriage. The analysis of vaginal microbiota during pregnancy in women having a history of miscarriage may contribute to understanding the importance of specific types of vaginal flora in the development of processes resulting in spontaneous abortion or preterm birth. This study was undertaken to evaluate the vaginal flora in the 1st trimester of pregnancy in women having a history of miscarriage. Study design, materials, and methods. To participate in the study, 160 individuals in the 1st trimester of pregnancy with and without a history of miscarriage were invited. Group 1 included 100 women with a history of miscarriage, group 2 consisted of 60 women without a history of miscarriage. The vaginal flora was analyzed with microscopic, bacteriological, and quantitative real-time PCR methods. Results. In patients with a history of miscarriage, the frequency of dysbiotic disorders of the vaginal flora was three times higher (11.0% and 3.3%) and pH value of the vaginal fluid was significantly higher. Along with a significant reduction of the proportion of the Lactobacillus flora in the 1st trimester of pregnancy in patients having a history of miscarriage, there was a significant increase in the abundance of opportunistic microorganisms, mostly aerobic flora, such as Enterobacteriaceae, Streptococcus spp., and Staphylococcus spp. Furthermore, there was a significant predominance of Ureaplasma spp. and Candida spp. in women with a miscarriage history. Conclusion. The vaginal microbiota in the 1st trimester of pregnancy in women having a history of miscarriage is characterized by higher pH values of the vaginal fluid, the prevalence of opportunistic microorganisms, a decrease in the abundance of the Lactobacillus flora, and a higher concentration of aerobic bacteria, Ureaplasma spp., and Candida spp. These findings indicate dysbiotic disorders of the vaginal microbiocenosis in women having a history of miscarriage, which can lead to late miscarriage and pretem birth.

There is substantial evidence that urogenital infection is one of the major causes of preterm birth, with bacterial vaginosis being one of these infections. Timely diagnosis and treatment of this condition significantly reduce the rate of preterm birth. The aim of this study was to evaluate the method of pH determination of vaginal fluid in women at a risk of preterm birth. A total of 66 women were included in the study. The women were divided into two groups. Group 1 consisted of 30 women, who measured vaginal pH from week 12 and 36 of gestation twice a week using the test рН-Balance (PremiumDiagnostics, Germany). Group 2 comprised 36 women, who did not measure vaginal pH (control group). Abnormal рН (>4,4) were observed in 9 women (30.0 %). Of them, in 8 women a urogenital infection was observed. All patients received etiotropic treatment. pH measuring in women with a history of miscarriage resulted in 4.5-fold reduction of preterm birth (from 30.0 to 6.7 %). In the control group the was no significant reduction in the rate of preterm birth (from 22.2 to 19.4 %).

SummaryHeparin cofactor II (HC II) levels were measured by electroimmunoassay in healthy volunteers, and patients with liver disease, DIC, proteinuria or a history of venous thrombosis. Analysis of the data in 107 healthy volunteers revealed that plasma HC II increases with age (at least between 20 and 50 years). HC II was found to be decreased in most patients with liver disease (mean value: 43%) and only in some patients with DIC. Elevated levels were found in patients with proteinuria (mean value 145%). In 277 patients with a history of unexplained venous thrombosis three patients were identified with a HC II below the lower limit of the normal range (60%). Family studies demonstrated hereditary HC II deficiency in two cases. Among the 9 heterozygotes for HC II deficiency only one patient had a well documented history of unexplained thrombosis. Therefore the question was raised whether heterozygotes for HC II deficiency can also be found among healthy volunteers. When defining a group of individuals suspected of HC II deficiency as those who have a 90% probability that their plasma HC II is below the 95% tolerance limits of the normal distribution in the relevant age group, 2 suspected HC II deficiencies were identified among the healthy volunteers. In one case the hereditary nature of the defect could be established.It is concluded that hereditary HC II deficiency is as prevalent among healthy volunteers as in patients with thrombotic disease. Further it is unlikely that heterozygosity for HC II deficiency in itself is a risk factor for the development of venous thrombosis.

Study objective. To evaluate the efficacy of intrauterine administration of autologous peripheral blood mononuclear cells (PBMC) prior to embryo transfer in patients with recurrent implantation failures in IVF program. Materials and methods. The study enrolled 129 patients with recurrent implantation failures in an IVF programme. Group 1 - 42 patients who had intrauterine administration of autologous PBMC activated with hCG (Pregnyl 500 IU). Group 2 - 42 patients who had intrauterine administration of autologous PBMC without hCG activation. Group 3 (placebo) - 45 patients who had intrauterine administration of saline. Study results. In the hCG-activated PBMC group, the rates of positive blood hCG tests, implantation, and clinical pregnancy were significantly higher than the respective rates in the non-activated PBMC group and in the placebo group, both in a stimulated cycle and in an FET cycle (р≤0.05). Conclusion. Intrauterine administration of autologous PBMC prior to embryo transfer in an IVF/ICSI programme increases the efficacy of IVF program in patients with a history of recurrent implantation failures.

Background: Ectopic pregnancy is one in which the fertilized ovum is implanted and develops outside the endometrial cavity. It is an important cause of maternal morbidity and mortality in first trimester. The present study was conducted to study the risk factors, clinical presentation and management of ectopic pregnancy in RIMS, Ranchi, Jharkhand, India.Methods: This was a prospective study conducted in the department of obstetrics and gynaecology, RIMS, Ranchi, Jharkhand during May 2017 to September 2018. A total of 90 cases were included in the study.Results: 80% of the patients presented with amenorrhoea, 98% had abdominal pain and 69% had vaginal bleeding. Ultrasonography revealed hemoperitoneum in about 93% patients. 16 (18%) patients had history of infertility whereas 10 patients (11%) had taken treatment of infertility.6 (7%) patients had history of STD or PID.14 (16%) had undergone bilateral tubectomy.2 (2%) had history of IUCD insertion and 12 (13%) patients had undergone previously lscs. 54 patients (60%) had undergone D and C and 6 patients (7%) had a previous history of ectopic pregnancy. 68 (76%) underwent only salpingectomy.12 (13%) had salpingo-oophorectomy and 10 (11%) had salpingectomy with contralateral tubectomy.Conclusions:Diagnosis of ectopic pregnancy requires clinical suspicion and supportive investigations like UPT, ultrasonography, β HCG and laparoscopy. It is an important cause of admission to RIMS as maternal near miss cases.Background: Ectopic pregnancy is one in which the fertilized ovum is implanted and develops outside the endometrial cavity.

Fungal infections and invasive mycoses, despite the continuous medicine progress, are an important globally therapeutic problem. Multicompartment dosage formulations (e.g., microparticles) ensure a short drug diffusion way and high surface area of drug release, which as a consequence can provide improvement of therapeutic efficiency compared to the traditional drug dosage forms. As fucoidan is promising component with wide biological activity per se, the aim of this study was to prepare fucospheres (fucoidan microparticles) and fucoidan/gelatin microparticles with posaconazole using the one-step spray-drying technique. Pharmaceutical properties of designed fucospheres and the impact of the gelatin addition on their characteristics were evaluated. An important stage of this research was in vitro evaluation of antifungal activity of developed microparticles using different Candida species. It was observed that gelatin presence in microparticles significantly improved swelling capacity and mucoadhesiveness, and provided a sustained POS release. Furthermore, it was shown that gelatin addition enhanced antifungal activity of microparticles against tested Candida spp. strains. Microparticles formulation GF6, prepared by the spray drying of 20% fucoidan, 5% gelatin and 10% Posaconazole, were characterized by optimal mucoadhesive properties, high drug loading and the most sustained drug release (after 8 h 65.34 ± 4.10% and 33.81 ± 5.58% of posaconazole was dissolved in simulated vaginal fluid pH 4.2 or 0.1 M HCl pH 1.2, respectively).

AbstractBackgroundSirenomelia, also called mermaid syndrome, is a rare lethal multi-system congenital deformity with an incidence of one in 60,000–70,000 pregnancies. Sirenomelia is mainly characterized by the fusion of lower limbs and is widely associated with severe urogenital and gastrointestinal malformations. The presence of a single umbilical artery derived from the vitelline artery is the main anatomical feature distinguishing sirenomelia from caudal regression syndrome. First-trimester diagnosis of this disorder and induced abortion may be the safest medical option. In this report, two cases of sirenomelia that occurred in an white family will be discussed.Case presentationWe report two white cases of sirenomelia occurring in a 31-year-old multigravid pregnant woman. In the first pregnancy (18 weeks of gestation) abortion was performed, but in the third pregnancy (32 weeks) the stillborn baby was delivered by spontaneous vaginal birth. In the second and fourth pregnancies, however, she gave birth to normal babies. Three-dimensional ultrasound imaging showed fusion of the lower limbs. Neither she nor any member of her family had a history of diabetes. In terms of other risk factors, she had no history of exposure to teratogenic agents during her pregnancy. Also, her marriage was non-consanguineous.ConclusionThis report suggests the existence of a genetic background in this mother with a Mendelian inheritance pattern of 50% second-generation incidence in her offspring.

Abstract Objectives Identify missed opportunities for the prevention and early diagnosis of congenital toxoplasmosis (CT) in infants followed up in a reference center for pediatric infectious diseases (PID) in Rio de Janeiro between January 2007 and December 2016. Methods Descriptive study including infants with CT, diagnosis established based on Brazil’s Ministry of Health’s criteria. All data regarding the infants and their mother’s prenatal care were collected from the medical records of the Instituto de Puericultura e Pediatria Martagão Gesteira (IPPMG)—a tertiary public pediatric university hospital. The study enrolled infants aged between 0 and 12 months followed up in the PID department of IPPMG and with confirmed infection by Toxoplasma gondii in the period between January 2007 and December 2016. All patients with diagnosis of CT registered in the PID database of the IPPMG and admitted in the above-mentioned period were included in the study. Patients whose records were not available, or who went to just one clinic appointment were excluded. Results The obstetric history of all 44 women, whose infants (45) were diagnosed with CT, was analyzed. Their median age was 22 years. None had undergone preconception serological testing for toxoplasmosis. Only 20 (45%) of them started antenatal care during the first trimester of gestation, a total of 24 (55%) had more than six antenatal care visits, and 16% of those did not undergo serological testing for toxoplasmosis. None were adequately informed of preventive measures. The diagnosis of acute toxoplasmosis was made in 50% of these pregnancies but 32% of the women were not treated. Only 10 children of these mothers were adequately screened and treated at birth. Conclusion Despite the existence of national recommendations, several opportunities were missed to prevent CT during the antenatal period and to diagnose and treat this condition in the neonatal period.

AimsMyeloid neoplasms occur in the setting of chronic lymphocytic leukaemia (CLL)/CLL-like disease. The underlying pathogenesis has not been elucidated.MethodsRetrospectively analysed 66 cases of myeloid neoplasms in patients with CLL/CLL-like disease.ResultsOf these, 33 patients (group 1) had received treatment for CLL/CLL-like disease, while the other 33 patients (group 2) had either concurrent diagnoses or untreated CLL/CLL-like disease before identifying myeloid neoplasms. The two categories had distinct features in clinical presentation, spectrum of myeloid neoplasm, morphology, cytogenetic profile and clinical outcome. Compared with group 2, group 1 demonstrated a younger age at the diagnosis of myeloid neoplasm (median, 65 vs 71 years), a higher fraction of myelodysplastic syndrome (64% vs 36%; OR: 3.1; p<0.05), a higher rate of adverse unbalanced cytogenetic abnormalities, including complex changes, −5/5q- and/or −7/7q- (83% vs 28%; OR: 13.1; p<0.001) and a shorter overall survival (median, 12 vs 44 months; p<0.05).ConclusionsMyeloid neoplasm in the setting of CLL/CLL-like disease can be divided into two categories, one with prior treatment for CLL/CLL-like disease and the other without. CLL-type treatment may accelerate myeloid leukaemogenesis. The risk is estimated to be 13-fold higher in patients with treatment than those without. The causative agent could be attributed to fludarabine in combination with alkylators, based on the latency of myeloid leukaemogenesis and the cytogenetic profile.

AbstractProgesterone appears to be the dominant hormone not only establishing a proper secretory endometrial development but also adequate decidualization to establish pregnancy and sustain pregnancy development. Progesterone is the natural immunoregulator to control the maternal immune system and not to reject the allogeneic fetus. There are two sources of progesterone: corpus luteum first and placenta later. Three progestogens can be used in pregnancy: (i) progesterone (per os, intravaginal and intramuscular), (ii) dydrogesterone (per os), and (iii) 17α-hydroxyprogesterone caproate (intramuscular). There are three indications, for which these progestogens can be clinically used either for treatment or prevention: (i) first trimester threatened and recurrent (habitual) abortion, (ii) premature labor/premature birth, and (iii) pre-eclampsia (hypertension in pregnancy). The available data are limited and only partially randomized. In threatened abortion the use of progesterone, dydrogesterone and 17α-hydroxyprogesterone caproate leads to a significant improved outcome, when at the time of threatened abortion a viable fetus has been ascertained by ultrasound. For prevention of recurrent abortion there are also some data indicating a significant effect compared with women without progestogen treatment. Prevention of preterm birth by progestogens (progesterone vaginally, orally and 17α-hydroxyprogesterone caproate intramuscularly) was significantly effective. The main study groups include pregnant women with a previous history of premature birth. However, also in women with shortened cervix use of progesterone seems to be helpful. The studies done so far in women with risk factors for pre-eclampsia or established pre-eclampsia were based on parenteral progesterone application. However, new studies are urgently needed.
