OBJECTIVE The purpose of this study was to evaluate the diagnostic accuracies of 2 free thyroxine immunoassays during pregnancy. STUDY DESIGN Serum was collected from healthy, thyroid peroxidase antibody-negative women during each trimester and nonpregnant controls. Thyrotropin, total T4 (TT4), free T4 index (FT4I), and 2 different FT4 immunoassays were(More)
OBJECTIVES To determine the rate and associated risk factors for recurrent shoulder dystocia (SD). STUDY DESIGN A retrospective analysis was performed of patients delivered from January 1991 to June 2001. Patients with and without recurrent SD were identified and compared. RESULTS Among the 267,228 vaginal births during the study period, there were 1904(More)
The arcuate line is a relevant structure when reconstructing the abdominal wall after rectus abdominis musculocutaneous flap harvest. Its location is classically taught to be half the distance from the pubic symphysis to the umbilicus, but recent anatomic literature provides evidence to the contrary. Better understanding of the relationship between the(More)
Oxysterol-binding proteins (OSBPs) have been described in a wide range of eukaryotes, and are often found to be part of a multi-gene family. We have used bioinformatics and data mining as a starting point for identifying new family members in humans based on the presence of the OSBP signature EQVSHHPP. In addition to OSBP and the recently reported OSBP2, we(More)
We sought to determine relative mRNA expression of AKR1C1 and SRD5A1, which respectively encode for the key progesterone metabolizing enzymes, 20alpha-hydroxysteroid dehydrogenase and 5alpha-reductase type 1, in the myometrium and chorioamniotic membranes during human spontaneous or induced labor and nonlabor. Quantitative real-time reverse-transcriptase(More)
OBJECTIVE To compare the obstetrical outcomes of term pregnancies induced with one of four commonly used labor induction agents. METHODS This is a retrospective cohort study of induced deliveries between 1 August 1995 and 31 December 2007 occurring at the Los Angeles County + University of Southern California Medical Center. Viable, singleton, term(More)
OBJECTIVE To establish the prevalence of intrahepatic cholestasis of pregnancy (ICP) in a primarily Latina population in the United States. STUDY DESIGN Over a period of 16 months, a convenience sample of subjects admitted to labor and delivery in the third trimester was enrolled. Each subject completed a questionnaire rating their severity of pruritus on(More)
INTRODUCTION We studied the time course of nitric oxide expression in the healing wound and the cell populations responsible for its synthesis. METHODS Twenty four Lewis rats underwent subcutaneous implantation of polyvinyl alcohol sponges. Rats were sacrificed in groups of three on days 1, 3, 5, 7, 10, 14, and 35 after wounding. The conversion of(More)
OBJECTIVE Shoulder dystocia (SD) and brachial plexus palsy (BPP) are complications of childbirth that can result in significant long-term sequelae. The purpose of the present study was to analyze risk factors in cases of SD and BPP. METHODS We performed a retrospective study of laboring women who delivered a singleton, term, live-born infant at the Los(More)
OBJECTIVE Previous studies have shown an association between the use of traditional anticonvulsants (e.g. phenytoin, carbamazepine, valproate) and decreased bone mineral density (BMD). However, there are limited data regarding the effects of newer anticonvulsants (e.g. gabapentin, levetiracetam, topiramate) on BMD. The aim of this study was to examine the(More)
