ObjectiveTo evaluate the performance of the preeclampsia (PE) screening algorithm of the Fetal Medicine Foundation (FMF) during the first trimester in a Brazilian population using maternal characteristics, mean arterial pressure (MAP), and uterine artery Doppler data.MethodsThis is a prospective cohort study that evaluated 701 pregnant women during the first trimester ultrasound screening for chromosomal abnormalities (11–13+6 weeks). All patients provided information regarding clinical and obstetric history, MAP, and mean uterine artery pulsatility index (mean PI). Patients were assigned to four groups based on the presence of PE and gestational age at delivery: group 1 (control), patients without hypertensive disorders (n=571); group 2, PE and delivery before 34 weeks of gestation (n=7); group 3, PE and delivery before 37 weeks of gestation, including patients from group 2 and patients that presented PE with delivery between 34 and 37 weeks (n=17); and group 4, PE and delivery before 42 weeks of gestation, including patients from both groups 2 and 3 and patients that presented PE with delivery between 37 and 42 weeks of gestation (n=34).ResultsAfter the exclusion of 96 patients, we evaluated the data of 605 patients. By combining maternal characteristics, MAP, and the mean uterine artery PI for the detection of PE, we found a sensitivity of 71.4% in group 2, 50% in group 3, and 41.2% in group 4 (false positive rate=10%).ConclusionUsing maternal characteristics, MAP, and uterine artery Doppler data, we were able to identify a significant proportion of patients who developed preterm PE.

Cesarean scar ectopic pregnancy is a rare type of ectopic pregnancy with high morbidity and mortality. Use of conservative conducts, including medical management with methotrexate, has avoided mutilating surgeries such as hysterectomy and spared the fertility of women. We report the case of a 30-year old patient with a cesarean scar ectopic pregnancy, with a live embryo, who was treated locally with transvaginal ultrasound-guided injection of methotrexate, complemented with various doses of systemic methotrexate.

Case 1: A 33 year woman booked in her second pregnancy, with one previous term vaginal delivery, presented at 11 weeks gestation with vaginal bleeding. Ultrasound scan in the early pregnancy unit confirmed a viable pregnancy with a cystic placenta. Subsequent scans showed progression of the cystic changes in the placenta, with normal growth and anatomy in the fetus. Amniocentesis confirmed normal fetal karyotype. The pregnancy is ongoing, with an apparently normal fetus and currently 21 weeks gestation. Case 2: A 25 year woman para 2, with two previous vaginal deliveries presented at 12 weeks gestation with vaginal bleeding. Ultrasound scan showed a dichorionic pregnancy with viable fetus in 1 sac and a complete mole in the other. She declined invasive testing, and her baseline HCG level was more than 90,000IU and had a normal thyroid function test. Anomaly scan was reported normal. Unfortunately she had a spontaneous miscarriage at 23 weeks gestation. Discussion: The prenatal diagnosis of molar pregnancy with viable fetus is based on ultrasound findings, abnormally elevated β-hCG levels and fetal karyotype. Prenatal diagnosis by chorionic villus sampling, amniocentesis, or fetal cord blood sampling helps to distinguish between diploid and triploid fetuses. Early multi-disciplinary involvement including Consultant obstetrician, fetal medicine specialist, neonatologist and Regional Trophoblastic screening center helps improve the outcomes.

She was diagnosed during the 5th pregnancy week with a 6cm cyst and presented during the 12th week acute pain in the right hypochondrium, nausea and vomiting. A well defined mass was palpable. Sonography revealed an ovarian cyst of 10cm, located on the right side. The Doppler examination did not reveal pathologic modifications . Laparoscopy was performed and a triple torsioned ovarian cyst had shifted the left ovary into the right hypochondrium.There were no signs of pedicular trombosys. Detorsion of the ovary and cystectomy were performed. Histopathological examination showed a benign serous cyst. The pregnancy is being followed up, currently in it the 30th week. Although surgical antepartum interventions are considered safe, abdominal surgery carries some risks to the pregnant woman and unborn fetus, so the choice of management necessitates a weighing of risks based on the gestational age and the characterisation of the adnexal mass.
