BACKGROUND A spontaneous intra-amniotic hemorrhage is rarely encountered during pregnancy. The correct diagnosis and management are problematic because of the infrequency of this condition and the high likelihood of a misdiagnosis. CASE REPORT A primigravida with an uncomplicated pregnancy and a normal targeted ultrasound presented late in the second trimester of pregnancy with antepartum bleeding of unknown origin. A repeat ultrasound was suggestive of an abdominal wall defect (gastroschisis). The patient continued to have antepartum bleeding and developed uterine contractions and abdominal pain necessitating frequent visits to labor and delivery...

Intrauterine growth restriction (IUGR) is a common pregnancy complication and is a leading cause of fetal morbidity and mortality. Placental hypoxia contributes to adverse fetal consequences, including IUGR. Exposing pregnant rats to hypoxia can lead to IUGR; however, assessment of maternal vascular function in a rat model of hypoxia, and the mechanisms that may contribute to adverse pregnancy outcomes, has not been extensively studied. We hypothesized that exposing pregnant rats to hypoxia will affect maternal systemic vascular function and increase the uterine artery resistance index (RI), which will be associated with IUGR...

In this prospective cohort study, one hundred participants were allocated into four groups according to their body mass indices. Vaginal ultrasound was performed at enrolment to measure cervical length. The shortest cervical measurement was recorded. Overweight and obese groups had significantly longer mean cervical length than women in the normal weight group when measured at 20-22 weeks of gestation (p < .001). Underweight women had the shortest mean cervical length. The incidence of preterm delivery was the highest in underweight women (RR; 1...

Many of the uterine infertility factors are associated with chronic endometritis. Its prevalence reaches 92.6%. Quality of endometrial transformation during the "implantation window" is the basis of successful fertility. In our retrospective comparative study of 101 in vitro fertilization (IVF) cycles, the efficacy of transvaginal Doppler ultrasound (TVDUS) in predicting successful implantation was evaluated. Inclusion criteria were as follows: age younger than 41 years and good quality of embryos. Exclusion criteria were as follows: 41 and older age, poor quality of embryos and uterine cavity lesions...

The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...

BACKGROUND: Rectus sheath hematoma is a rare clinical diagnosis, particularly in pregnancy. Due to unspecific symptoms, misdiagnosis is likely and could potentially endanger a patient as well as her fetus. CASE PRESENTATION: A 26-year-old white woman presented with mild right-sided abdominal pain, which increased during palpation and movement, at 26 + 3 weeks' gestational age. Ultrasound imaging initially showed a round and well-demarcated structure, which appeared to be in contact with her uterine wall, leading to a suspected diagnosis of an infarcted leiomyoma...

BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing...

Orofacial clefts are the most common congenital craniofacial anomalies and can occur as an isolated defect or be associated with other anomalies such as posterior fossa anomalies as a part of several genetic syndromes. We report two consecutive voluntary pregnancy interruptions in a nonconsanguineous couple following the fetal ultrasound finding of cleft lip and palate and posterior fossa anomalies confirmed by means of post-termination examination on the second fetus. The quantitative fluorescent PCR, the karyotype, and the comparative genomic hybridization-array analysis after amniocentesis were normal...

A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...
