OBJECTIVE To describe a new ultrasound technique that may be useful for the diagnosis of micrognathia in the first trimester of pregnancy. METHODS The retronasal triangle (RNT) view is a technique that captures the coronal plane of the face in which the primary palate and the frontal processes of the maxilla are visualized simultaneously. Normal first-trimester fetuses display a characteristi...
The aim of present study was to establish normative data for the distribution of nuchal translucency (NT) thickness in normal Korean fetuses. The data were collected from pregnant women with singleton pregnancies in whom fetal ultrasound was performed and the fetal NT thickness was measured between 11 and 14 weeks of gestation. Among them, a total of 2,577 fetuses with a known normal outcome we...
We performed aspiration of early pregnancy on 100 women requesting termination, using a low caliber angled catheter under sonographic guidance, without analgesia or anesthesia. The sonographic inclusion criteria for the study were: (1) mean gestational sac diameter less than 30 mm, or (2) crown rump length less than 10 mm when an embryo was visualized. The uterine content was successfully evacu...
OBJECTIVE In a refugee camp on the Thai-Burmese border, accurate dating of pregnancy relies on ultrasound measurements obtained by locally trained health workers. The aim of this study was to substantiate the accuracy of fetal biometry measurements performed by locally trained health workers by comparing derived reference equations with those published for Asian and European hospitals. METHOD...
Our laboratory has demonstrated that Yorkshire placentae increase in size and surface area during the final third of gestation. In contrast, Meishan placental size remains constant during late gestation, but the density of blood vessels at the placental-endometrial interface increases markedly. Preliminary observations from our laboratory suggest that if one of two adjacent Meishan fetuses dies...
BACKGROUND Our objective was to determine what effect maternal BMI has on fetal growth rate in the early first trimester. METHODS This was a prospective observational study of singleton pregnancies with certain dates, initially presenting for a transvaginal scan (TVS) before 12 weeks of gestation. Maternal characteristics (BMI, ethnicity, maternal age, obstetric history, abdominal pain and va...
Objective To evaluate the association between demographic and ultrasound variables major intra-operative blood loss during surgical transcervical evacuation of live caesarean scar pregnancies. Study Design This was a retrospective cohort study conducted in tertiary referral center 2008 2019. We included all women diagnosed with ectopic pregnancy who chose to have management center. A preoperati...
We present data on prenatal growth, development, and skeletal ossification for the Angolan free-tailed bat (Mops condylurus), a species distributed throughout sub-Saharan Africa. Specimens were measured for crown–rump length (CRL), greatest length of the skull (GLS), forearm length, mass, and wing area. We cleared and differentially stained specimens for cartilage and bone to quantify pattern o...
