AbstractAim of work:To determine whether fetal volume (FV) measured by three-dimensional (3D) ultrasound was able to detect fetuses at risk of low birth weight (primary outcome) and/or preterm labor (secondary outcome).Methods:One hundred pregnant women carrying a singleton living pregnancy who were sure of dates, and had a dating scan, with gestational age between 11 weeks and 13 weeks+6 days coming for routine first trimester nuchal translucency (NT) were examined by both two-dimensional (2D) and 3D ultrasound (Vocal System) for crown-rump length (CRL) and FV then followed up regularly every 4 weeks until 28 weeks then biweekly until 36 weeks then weekly until delivery both clinically and by ultrasound biometry.Findings:Eighty-seven cases had a normal outcome, while the remaining 13 cases had either preterm labor (four cases) or low-birth weight (nine cases). FV positively correlated with CRL (P=0.026), gestational age in weeks (P=0.002), neonatal body weight in grams (P=0.018) and neonatal body length at birth (P=0.04). A mean FV of 8.3 mmConclusion:3D assessment of FV in the first trimester provides an accurate method for predicting pregnancy outcome namely low birth weight and neonatal complications, however, it is a better positive predictor than a negative one.

Hypothesis/aims of study. Miscarriage is a significant medical and social problem. The etiology of pregnancy losses is diverse and depends on many factors. It is believed that dysbiotic disorders of the vagina are one of the main causes of this pathology. While the etiopathogenesis of miscarriage is actively studied, many questions still remain open. The aim of the study was to investigate anamnestic and microbiological predictor factors of miscarriage. Study design, materials, and methods. In a prospective cohort study, 159 pregnant women were examined in the first trimester of pregnancy: the anamnesis, course of pregnancy, vaginal microflora, and present pregnancy outcome were studied. The vaginal microflora was analyzed using microscopic, bacteriological and quantitative real-time PCR methods. Depending on the present pregnancy outcome, the patients were divided into two groups: those delivered at term and women with early and late miscarriage. The analysis of predictors of miscarriage of the ongoing pregnancy was performed depending on the period of delivery. Results. The rate of miscarriage in women was 13%. The independent predictors of early miscarriage were chronic endometritis (OR 10.54; 95% CI 2.54 to 43.64), the dominance of Lactobacillus iners in the vaginal microflora (OR 8.52; 95% CI 2.07 to 35.05), and the prevalence of non-Lactobacillus species in microscopy of vaginal preparations (OR 4.50; 95% CI 1.02 to 19.69). The dominance of Lactobacillus crispatus was a significant protective factor of late miscarriage (OR 0.20; 95% CI 0.04 to 0.99). Conclusion. The undertaken analysis revealed significant associations of a number of anamnestic and microbiological predictor factors with miscarriage, which will enable to substantiate approaches for predicting pregnancy outcomes at different gestational age and to develop methods of pre-conception care and treatment in women with different risk of miscarriage.

Objective: To study the prenatal developmental anatomy in first trimester of pregnancy in Khyber Pakhtun Khuwa. Materials and methods: The cross sectional study was conducted on 600 pregnant females visiting the antenatal clinic of Khyber Teaching Hospital Peshawar and Khyber clinic (Jamrud). The duration of study was 6 months. A pregnant women greater than 16 years of age, willing for ultrasound was selected, poor visualization due to technical factors like obesity, surgical scar were excluded. All the patients were enlisted under informed consent. Detailed obstetrical history was taken. The embryos were visualized with the help of abdominal ultrasound. Data were recorded followed by statistical analysis and presented as percentages. Results: In the present study, 591 cases (98.5%) were single, 8 (1.33%) cases were twin and one case is (0.16%) of triplets. The distributions of normal and abnormal cases were studied in first trimester. The shape of gestational sac was regular in 370(61.66%) and irregular in 230(38.33%) Yolk sacs were identified in 430(71.6%) cases, while in 170(28.33%) of cases yolk sac could not be identified. It could not be identified in 50 (8.33%) of cases due to early pregnancy and in 120 (20%) of cases due to abnormal pregnancy. The Fetal pole was detected in 150(25%) cases and could not be identified in 450 (75%) of cases. The relationship of gestational age, gestational sac and crown rump length in normal pregnancy was observed. Conclusions: There is linear increase in measurements of fetal growth parameters as the gestational age increases. For the assessment of gestational age in the first trimester, ultrasound is an accurate and useful modality. Key words: Trimester, Gestational sac, Yolk sac and Crown rump length.
