Objective: The aim of this study was to evaluate the accuracy of intrapartum cardiotocography in identifying acidemia at birth by umbilical cord blood gasometry in high-risk pregnancies.

Methods: This was a retrospective cohort study of singleton high-risk parturients using intrapartum cardiotocography categories I, II, and III. The presence of fetal acidemia at birth was identified by the analysis of umbilical cord arterial blood pH (<7.

Accuracy of intrapartum cardiotocography in identifying fetal acidemia by umbilical cord blood analysis in low-risk pregnancies.

Objective: The aim of this study was to evaluate the accuracy of intrapartum cardiotocography in identifying fetal acidemia by umbilical cord blood analysis in low-risk pregnancies.

Methods: This is a retrospective cohort study of low-risk singleton pregnancies in labor after performing intrapartum cardiotocography categories I, II, and III. The presence of fetal acidemia at birth was identified by analyzing the pH of umbilical cord arterial blood (pH<7.

Association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes.

Objective: The aim of this study was to evaluate the association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes.

Methods: This retrospective cohort included pregnant women with premature rupture of membranes (between 24 and 33+6 weeks) who used or did not use prophylactic antibiotics. Pearson's chi-square (χ²) test, Student's t-test, and binary logistic regression were used for statistical analysis.

Association of gloves change and surgical site complications in elective cesarean sections of low-risk pregnancies.

Background: The aim of this study was to assess whether the change of gloves is associated with reduced surgical site complications of elective cesarean sections in low-risk pregnancies.

Methods: A prospective and observational study was conducted, with 169 patients selected for elective cesarean sections, and divided into two groups: group 1 (N.=100) (no change of gloves); and group 2 (N.

Effect of grade 3 placenta <36 weeks of pregnancy on perinatal outcomes.

Background: The aim of this study was to assess whether the presence of grade 3 placenta <36 weeks of pregnancy is associated with adverse perinatal outcomes.

Methods: Retrospective cohort study in which patients were separated into the following three groups: 1) grade 3 placenta <36 weeks, 2) grade 3 placenta >36 weeks, 3) no occurrence of grade 3 placenta throughout pregnancy. The χ and general linear model tests were used to compare adverse perinatal outcomes.

Increased pulsatility index of uterine artery Doppler between 26 and 28 weeks of gestation and adverse perinatal outcomes.

Objective: To compare adverse perinatal outcomes in pregnant women with or without normalization of the mean pulsatility index (PI) uterine artery Doppler between 24 and 28 weeks of gestation.

Methods: Retrospective cohort which pregnant women were divided into three groups: normal uterine artery Doppler between 20-24 and 26-28 weeks (controls), abnormal uterine artery Doppler between 20-24 and normal between 26-28 weeks (anUtA), and abnormal uterine artery Doppler between 20-24 and 26-28 weeks (aaUtA). To compare adverse perinatal results between the groups Chi-square test was used.

Active Versus Expectant Management for Preterm Premature Rupture of Membranes at 34-36 Weeks of Gestation and the Associated Adverse Perinatal Outcomes.

Objective:  To compare the type of management (active versus expectant) for preterm premature rupture of membranes (PPROM) between 34 and 36 + 6 weeks of gestation and the associated adverse perinatal outcomes in 2 tertiary hospitals in the southeast of Brazil.

Methods:  In the present retrospective cohort study, data were obtained by reviewing the medical records of patients admitted to two tertiary centers with different protocols for PPROM management. The participants were divided into two groups based on PPROM management: group I (active) and group II (expectant).

Fetal structural anomalies diagnosed during the first, second and third trimesters of pregnancy using ultrasonography: a retrospective cohort study.

Background: The prevalence of congenital abnormalities in general populations is approximately 3-5%. One of the most important applications of obstetric ultrasound is in detection of fetal structural defects.

Objective: To assess fetal structural anomalies diagnosed using ultrasound in the three trimesters of pregnancy.

Perinatal Outcomes of Fetuses with Early Growth Restriction, Late Growth Restriction, Small for Gestational Age, and Adequate for Gestational Age.

Objective:  To evaluate the association between early-onset fetal growth restriction (FGR), late-onset FGR, small for gestational age (SGA) and adequate for gestational age (AGA) fetuses and adverse perinatal outcomes.

Methods:  This was a retrospective longitudinal study in which 4 groups were evaluated: 1 - early-onset FGR (before 32 weeks) ( = 20), 2 - late-onset FGR (at or after 32 weeks) ( = 113), 3 - SGA ( = 59), 4 - AGA ( = 476). The Kaplan-Meier curve was used to compare the time from the diagnosis of FGR to birth.

The impact of first-trimester intrauterine hematoma on adverse perinatal outcomes.

Purpose: The aim of this study was to evaluate whether the presence of an intrauterine hematoma (IUH) on an early pregnancy ultrasound scan showing a live fetus was related to adverse perinatal outcomes.

Methods: We performed a retrospective cohort study to evaluate pregnant women who underwent an ultrasound examination in early pregnancy, between 6 weeks 0 days and 10 weeks 6 days. We compared the perinatal outcomes between women with and without firsttrimester IUH using the Mann-Whitney and Fisher exact tests.

Second trimester cervical length measurement for prediction spontaneous preterm birth in an unselected risk population.

Objective: To assess the predictive capacity of cervical length (CL) measurement underwent during the second trimester ultrasound for prediction preterm birth <32, 34, and 37 weeks of gestation in an unselected risk population.

Methods: A retrospective cohort study was performed with 751 singleton pregnancies between 20 and 24+6 weeks of gestation. The CL measurement (mm) using the transvaginal route was obtained in a sagittal view and the calipers positioned to measure the linear distance between the triangular area of echodensity at the external os and the internal os.

Giant Condyloma (Buschke-Loewenstein Tumor) in a 16-year-old Patient: Case Report.

The Buschke-Loewenstein tumor is characterized by excessive growth of verrucous lesions on the genitals and/or perianal region. It is considered benign despite the high rate of recurrence and the possibility of malignant transformation. It is commonly associated with subtypes 6 and 11 of the human papillomavirus (HPV), and host's immunity plays an important role in the development of the disease.

[Influence of cause of death on body and internal organs weight in perinatal autopsies].

Purpose: To evaluate changes in body and internal organ weight of autopsied children in the perinatal period and their relationship with the cause of death.

Methods: One hundred and fifty three cases of perinatal autopsies performed at a university hospital in Southeastern Brazil ere included. Information about cause of perinatal death, date of autopsy, gestational age, perinatal weight and organ weight was obtained from the autopsy protocols and medical records of the mother and/or the newborn.
