Baraitser-Winter cerebrofrontofacial syndrome (BWCFF) is a variable multiple congenital anomaly condition, typically presenting postnatally with neurocognitive delays, distinctive facial features, cortical brain malformations, and in some, a variety of additional congenital malformations. However, only a few cases have reported the prenatal presentation of this syndrome. Here, we report two cases of BWCFF and their associated prenatal findings.

Introduction: Uterine incision based on the placental location in open maternal-fetal surgery (OMFS) has never been evaluated in regard to maternal or fetal outcomes.

Objective: The aim of this study was to investigate whether an anterior placenta was associated with increased rates of intraoperative, perioperative, antepartum, obstetric, or neonatal complications in mothers and babies who underwent OMFS for fetal myelomeningocele (fMMC) closure.

Methods: Data from the international multicenter prospective registry of patients who underwent OMFS for fMMC closure (fMMC Consortium Registry, December 15, 2010-June 31, 2019) was used to compare fetal and maternal outcomes between anterior and posterior placental locations.

Objective: Function of the lower extremities after prenatal myelomeningocele (MMC) repair is best assessed with ambulatory function at 30-36 months of age, but parents often ask about function before this milestone. Lower extremity movement can be assessed by ultrasound (US) and at the newborn exam (NE), but correlation between US, NE, and ambulation is not firmly established.

Methods: This was a retrospective correlation study of fetuses that underwent open prenatal MMC repair at SSM Cardinal Glennon Fetal Care Institute, St.

Background: Open maternal-fetal surgery for fetal myelomeningocele results in reduction in neonatal morbidity related to spina bifida but may be associated with fetal, neonatal, and maternal complications in subsequent pregnancies.

Objective: The objective of this study was to ascertain obstetric risk in subsequent pregnancies after open maternal-fetal surgery for fetal myelomeningocele closure.

Study Design: An international multicenter prospective observational registry created to track and report maternal, obstetric, fetal/neonatal, and subsequent pregnancy outcomes following open maternal-fetal surgery for fetal myelomeningocele was evaluated for subsequent pregnancy outcome variables.

The aim of this systematic review with meta-analysis was to evaluate the effect on length of labor when patients receive IVF with or without dextrose. Searches were performed in electronic databases from inception of each database to May 2018. Trials comparing intrapartum IVF containing dextrose (i.

Background: While microarray testing can identify chromosomal abnormalities missed by karyotyping, its prenatal use is often avoided in low-risk pregnancies due to the possible identification of variants of uncertain significance (VOUS).

Methods: We tested 2,970 prenatal samples of all referral indications using a rapid BACs-on-Beads-based assay with probes for sex chromosomes, common autosomal aneuploidies, and 20 microdeletion/microduplication syndromes, designed as an alternative to microarray in low-risk pregnancies and an alternative to rapid aneuploidy testing in pregnancies also undergoing microarray analysis.

Results: Interpretable results were obtained in 2,940 cases (99.

Objective: To demonstrate the usefulness of microarray testing in prenatal diagnosis based on our laboratory experience.

Methods: Prenatal samples received from 2004 to 2011 for a variety of indications (n = 5003) were tested using comparative genomic hybridization-based microarrays targeted to known chromosomal syndromes with later versions of the microarrays providing backbone coverage of the entire genome.

Results: The overall detection rate of clinically significant copy number alterations (CNAs) among unbiased, nondemise cases was 5.

Objective: The aim of this study is to understand the diagnostic utility of comparative genomic hybridization (CGH)-based microarrays for pregnancies with abnormal ultrasound findings.

Methods: We performed a retrospective analysis of 2858 pregnancies with abnormal ultrasounds and normal karyotypes (when performed) tested in our laboratory using CGH microarrays targeted to known chromosomal syndromes with later versions providing backbone coverage of the entire genome. Abnormalities were stratified according to organ system involvement.

In 2004, the American Podiatric Medical Association conducted its third annual "Best Walking City Competition." This study improved on the 2002 and 2003 studies by increasing the number of cities competing for the title of "Best Walking City" and by including a variety of new measures of walking activities to provide a more comprehensive and equitable basis for comparing cities. The top 20 best walking cities in 2004 were identified from among the 200 largest cities across the United States.

We report 2 cases of 47,XXX that were diagnosed prenatally and were screened positive for trisomy 21 by biochemical and ultrasound markers. These cases underline the importance of discussing the sex chromosome abnormalities during the genetic counseling after an abnormal triple screen test or ultrasound examination.

A 2004 survey of US adults found that 19% had experienced foot problems at work at some time. As a result, 38% reported lost productivity and 28% missed time at work. Younger, less educated male workers were more likely to suffer from foot problems.

In 2003, the American Podiatric Medical Association conducted its second annual "Walking City Competition." The objective of the study was to update and expand on the results of a previous study conducted in 2002, taking into account a wider variety of measures of walking and walking conditions and identifying the best cities for walking in the United States on a regional basis.

Background: Terbutaline has direct effects on the cardiac conduction system, but when used to treat preterm labor it is rarely associated with clinically significant cardiac arrhythmias. Commonly used drug references did not list atrial fibrillation as a complication of terbutaline, and our literature search found only one case of atrial fibrillation that occurred with parenteral administration.

It is well known that normal human cells placed in a culture environment exhibit a limited proliferative capacity. The extent to which the culture environment influences proliferative life span is not understood. This study evaluated the effects of the standard procedures used to establish and maintain cultures on the proliferative life spans of different types of human fibroblast cells established from fetal and adult skin and lung.
