Background: The cesarean delivery rate has been rising in recent years, having associated maternal morbidities. Elective induction of labor has also been seen to rise during this same time period.
Objective: This current study investigated the difference in the cesarean delivery rate between induction of labor and spontaneous labor among nulliparous, term, singleton, and vertex-presenting women.
Purpose: To offer obstetrical practitioners a current perspective about an important contemporary practice model which has implications that may not have been adequately recognized.
Methods: A description of individual past professional experience.
Results: A resultant perspective from decades of professional obstetric practice.

Background: Noninvasive prenatal testing (NIPT) based on cell-free DNA in maternal circulation has been accepted worldwide by the clinical community since 2011 but limitations, such as maternal malignancy and fetoplacental mosaicism, preclude its full replacement of invasive prenatal diagnosis. We present a novel silicon-based nanostructured microfluidics platform named as "Cell Reveal™" to demonstrate the feasibility of capturing circulating fetal nucleated red blood cells (fnRBC) and extravillous cytotrophoblasts (EVT) for cell-based noninvasive prenatal diagnosis (cbNIPD).
Methods: The "Cell Reveal™" system is a silicon-based, nanostructured microfluidics using immunoaffinity to capture the trophoblasts and the nucleated RBC (nRBC) with specific antibodies.
Objective: The objective of this study is to examine results of bacterial cultures of the cervix prior to cerclage placement and how these may be used to guide prophylactic antibiotics.
Methods: All patients undergoing cerclage between 2000 and 2003 in a single, large community hospital were evaluated for indication for cerclage, signs and symptoms on presentation, transvaginal ultrasound cervical length findings, type of cerclage placed, type of anesthesia used, cervical culture taken, tocolytics given, gestational age at delivery, and complications surrounding delivery.
Results: Sixty-five cerclages were performed between 2000 and 2003, 13 (20%) prophylactic, 47 (72%) therapeutic, and five (8%) emergent.
Objective: To determine whether women with recurrent evidence of cervical insufficiency (CI) and with a history-indicated cerclage (HIC) placed at the beginning of the second trimester will deliver later than the index case.
Study Design: Retrospective case-control study of singleton pregnancy with history-consistent CI. Patients had a cerclage placed between 12 and 16 weeks of gestation.
Although co-amplification of polymorphic microsatellite markers is the current gold standard for preimplantation genetic diagnosis (PGD) of single-gene disorders (SGD), this approach can be hampered by the lack of availability of informative markers. We recently (2011) devised a novel in-house assay for PGD of aromatic L-amino acid decarboxylase deficiency, based on an amplification refractory mutation system and quantitative PCR (ARMS-qPCR). The objective of the present study was to verify ARMS-qPCR in a cohort of 20 PGD cycles with a diverse group of SGDs (15 couples at risk for 10 SGDs).

Methods: Amniotic fluid and serum were drawn from women in the second trimester of pregnancy. The study group included 2 women pregnant with normal fetuses and 4 with fetuses displaying myelomeningocele (n = 1), anencephaly (n = 1), holoprosencephaly (n = 1), or encephalocele (n = 1).
Fetal chylothorax (FC) is a rare condition characterized by lymphocyte-rich pleural effusion. Although its pathogenesis remains elusive, it may involve inflammation, since there are increased concentrations of proinflammatory mediators in pleural fluids. Only a few hereditary lymphedema-associated gene loci, e.

Methods: Study participants (10 weeks 4 days through 19 weeks 0 days) underwent a 3-D rendering of the fetal face and ear along with other biometric measurements prior to invasive testing.
Results: Of the 348 patients who underwent chorionic villi sampling (CVS) (n = 208) or amniocentesis (n = 140), 18 were diagnosed with trisomy 21, 4 with trisomy 18, and 1 with trisomy 13.
Objective: Walker-Warburg syndrome (WWS) is a genetically heterogeneous congenital muscular dystrophy caused by abnormal glycosylation of alpha-dystroglycan (alpha-DG) that is associated with brain malformations and eye anomalies. The Fukutin (FKTN) gene, which causes autosomal recessively inherited WWS is most often associated with Fukuyama congenital muscular dystrophy in Japan. We describe the clinical features of four nonconsanguinous Ashkenazi Jewish families with WWS and identify the underlying genetic basis for WWS.

Study Design: Ultrasound (<24 weeks gestational age (GA)) and newborn outcome data collected prospectively since 1986 were analyzed retrospectively.
In a dizygotic pregnancy within monochorionic placenta, findings consistent with chimerism were detected. Monochorionicity was confirmed by a combination of ultrasound, histological evaluation and DNA technology. Etiologic hypotheses are offered to explain this rare circumstance.
