To assess perinatal and long-term follow-up outcomes of fetal cervical masses diagnosed by three-dimensional (3D) magnetic resonance imaging (MRI) and 3D virtual models. This retrospective cohort study evaluated 15 pregnant women (age, 21-38 years) at 29-40 weeks of singleton gestation, whose fetuses exhibited congenital oral and cervical masses. These women were referred to our facility because of suspected fetal malformations on routine obstetric ultrasound, and the cases were confirmed, excluded, or complemented by MRI.

Although ultrasound is still the gold standard for the assessment of fetal malformations, magnetic resonance imaging (MRI) has gained great prominence in recent years. In situations in which ultrasound has low sensitivity, such as maternal obesity, abdominal scarring, and oligohydramnios, MRI has proven to be a safe and accurate method. Regarding fetal abdominal wall defects, MRI appears to be widely used in the prognostic assessment of gastroschisis with intestinal atresia or of complications of omphalocele, allowing better perinatal management and parental counseling.

Article Synopsis
  • Fetal MRI is increasingly used alongside ultrasound for evaluating fetal disorders, benefiting from advancements in imaging technology.
  • Fetal MRI excels in cases with challenges like maternal obesity or abnormal fetal positioning, allowing for better assessment of large organs and complex malformations.
  • The article reviews recent literature on the use of fetal MRI for examining the fetal abdomen, detailing imaging techniques, protocols, and common clinical uses.

Objective: To describe the methodological features of a study on the association between restricted intrauterine growth and prevalence of overweight, obesity and hypertension in school aged children.

Methods: The study was conducted in two stages in two public schools in Niterói (RJ), from June through December 2010. All students aged 6 to 14 years were eligible to participate.

Background: Neonatal effects of drugs administered to mothers before delivery depend on the quantity that crosses the placental barrier, which is determined by the pharmacokinetics of the drug in the mother, fetus, and placenta. Diabetes mellitus can alter the kinetic disposition and the metabolism of drugs. This study investigated the placental transfer of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women with gestational diabetes mellitus (GDM) submitted to peridural anesthesia.

Purpose: To evaluate the perinatal factors that influence the incidence of necrotizing enterocolitis (NEC) in newborns infants (NBI) weighing less than 1,500 g.

Methods: A prospective study that analyzed all infants with birth weight (BW) less than 1,500 g born between January 2006 to December 2010 (n=183). They were divided into two groups, i.

The Crohn's disease, a form of inflammatory bowel disease, is frequent in women of childbearing age. Its management requires greater attention during pregnancy. We report a case of refractory Crohn's disease in a pregnant patient that evolued to ileocolectomy at puerperium.

The aim of this study is to determine the concentrations of lidocaine and its metabolite, monoethylglycine xylidide (MEGX), and of the enantiomers of bupivacaine in maternal and fetal compartments. Ten healthy pregnant women were submitted to epidural anesthesia. Drug concentrations were determined in the maternal vein, fetal umbilical artery and vein, and the placental intervillous space.

Background: Fentanyl is used in obstetrical practice to promote analgesia and anesthesia during labor and in cesarean delivery, with rapid and short-term effects.

Objective: To determine fentanyl concentrations in maternal plasma, in the placental intervillous space, and in the umbilical artery and vein in term pregnant women.

Patients And Methods: Ten healthy pregnant women underwent epidural anesthesia with fentanyl plus bupivacaine and lidocaine, and fentanyl concentrations were determined in the various maternal and fetal compartments, including the placental intervillous space, which has not been previously studied in the literature.

Background: Peridural blockade with lidocaine, bupivacaine, and fentanyl is an anesthetic procedure extensively used in obstetrics, justifying the pharmacokinetic study of these drugs during labor.

Objective: To investigate the influence of the physiopathological changes of gestational diabetes mellitus (GDM) on the pharmacokinetics of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women subjected to peridural anesthesia.

Patients And Methods: Ten normal pregnant women (group 1) and six pregnant women with GDM (group 2) were studied, all of them at term.

The present study investigates the kinetic disposition with focus on the racemization, glucuronidation capacity and the transplacental transfer of lorazepam in term parturients during labor. The study was conducted on 10 healthy parturients aged 18-37 years with a gestational age of 36-40.1 weeks, treated with a single oral dose of 2 mg racemic lorazepam 2-9 h before delivery.

Background: Fentanyl is an opioid drug widely used as a co-adjuvant in abdominal delivery, a fact that justifies its pharmacokinetic study under these conditions.

Objective: Our objective was to investigate the pharmacokinetics and placental transfer of fentanyl in parturients whose pregnancies were resolved by cesarian section with epidural anesthesia.

Patients And Methods: Ten clinically normal parturients who delivered at term received 5 ml of 2% lidocaine hydrochloride without a vasoconstrictor for skin and subcutaneous blockade, followed by epidural injection of 2 ml fentanyl citrate (0.
