Rotation of the vermis as a cause of enlarged cisterna magna on prenatal imaging

Dandy–Walker complex is a continuum of developmental anomalies of the posterior fossa which includes vermian rotation. However, vermian rotation alone may be benign. The aim of this study was to describe our experience with sagittal‐plane prenatal ultrasound in the diagnosis of rotation of the vermis in cases of suspected enlarged cisterna magna on routine antenatal imaging, and to describe the follow‐up of these patients.

Three and four dimensional ultrasound: a novel method for evaluating fetal cardiac anomalies

To evaluate the role of various new models of 3‐ and 4‐dimensional (3D and 4D) ultrasound (US) applications in prenatal assessment of fetal cardiac anomalies.

Secondary cytomegalovirus infection can cause severe fetal sequelae despite maternal preconceptional immunity

To describe our experience in cases with sonographic signs of fetal infection and with maternal serological ‘immunity’ to cytomegalovirus (CMV) infection.

Fetal tricuspid annular plane systolic excursion (f‐TAPSE): evaluation of fetal right heart systolic function with conventional M‐mode ultrasound and spatiotemporal image correlation (STIC) M‐mode

Fetal tricuspid annular plane systolic excursion (f‐TAPSE) is a modified method to measure the vertical movement of the tricuspid valve annulus by M‐mode ultrasound, in order to assess the fetal right heart. Evaluation of right heart function is well‐recognized in pediatric and adult cardiology, but has not been studied widely in the fetus. We aimed to study f‐TAPSE in the second half of gestation in normal fetuses, to establish reference ranges for this measure, to evaluate the usefulness of spatiotemporal image correlation (STIC) M‐mode in obtaining it, and to compare conventional M‐mode and STIC M‐mode‐based measures of f‐TAPSE.

Ongoing Pregnancy Rates in Women with Low and Extremely Low AMH Levels. A Multivariate Analysis of 769 Cycles

Background The ideal test for ovarian reserve should permit the identification of women who have no real chance of pregnancy with IVF treatments consequent upon an extremely reduced ovarian reserve. The aim of the current study was to evaluate pregnancy rates in patients with low AMH levels (0.2–1 ng/ml) and extremely low AMH levels (<0.2 ng/ml) and to determine the cumulative pregnancy rates following consecutive IVF treatments. Methods We conducted an historical cohort analysis at a tertiary medical center. Serum AMH levels were measured at initial clinic visit and prior to all following treatment cycles in 181 women (769 cycles) with an initial AMH level ≤1 ng/ml, undergoing IVF-ICSI. Main outcome measures were laboratory outcomes and pregnancy rates. Results Seventy patients undergoing 249 cycles had extremely low AMH levels (≤0.2 ng/ml), whereas 111 patients undergoing 520 cycles had low AMH levels (0.21–1.0 ng/ml). Number of oocytes retrieved per cycle, fertilized oocytes and number of transferred embryos were significantly lower in the extremely low AMH levels group compared to the low AMH levels (P<0.003). Crude ongoing pregnancy rates were 4.4% for both groups of patients. Among 48 cycles of women aged ≥42 with AMH levels of ≤0.2 ng/ml no pregnancies were observed. But, in patients with AMH levels of 0.2–1.0 ng/ml, 3 ongoing pregnancies out of 192 cycles (1.6%) were observed. However, in a multivariate regression analysis adjusted for age and cycle characteristics, no significant differences in ongoing pregnancy rates per cycle between the two groups were evident. Cumulative pregnancy rates of 20% were observed following five cycles, for both groups of patients. Conclusions Patients with extremely low AMH measurements have reasonable and similar pregnancy rates as patients with low AMH. Therefore, AMH should not be used as the criterion to exclude couples from performing additional IVF treatments.
