To determine the fetal biophysical effects of vibroacoustic stimulation produced by an electronic artificial larynx we studied 20 normal term pregnancies assigned either to control (no stimulus) or experimental (stimulus) groups. Each fetus was observed for 3 hours; either no stimulus or a 3-second stimulus was delivered after the first hour. Fetal heart(More)
To study the effects of epidural anesthesia on uterine and umbilical artery blood flow in preeclampsia, we observed 25 patients in active labor at 36 or more weeks' gestation. Seven had preeclampsia, eight had chronic hypertension, and ten had no complications. Doppler velocimetry of the uterine and umbilical arteries was performed before and after(More)
Estrogen replacement therapy (ERT) prevents fractures and relieves vasomotor symptoms, but it increases the risk of endometrial cancer. Previous studies and national prescribing patterns show that physicians are conservative in their approach to this therapy. The authors interviewed physicians and perimenopausal women to assess their utilities for the(More)
OBJECTIVE To examine the relationship between training in induced abortion during residency and subsequent practice patterns in providing abortion services. STUDY DESIGN An anonymous survey of all obstetrician-gynecologists with admitting privileges at a tertiary care hospital in New England was conducted. Physicians were asked about their residency(More)
Assessment of cases of chronic pelvic pain presents a challenging problem, and many physicians overlook the association of sleep disorders and depression with such pain. We examined these linkages in our chronic pelvic pain clinic, using a questionnaire that assists in diagnosis and management of these cases. To date, the cases of 72 patients (both(More)
In a nationwide survey, chief administrative residents reported their views on how subspecialty fellowships affect their residency training in obstetrics and gynecology. The residents felt that fellows improve the quality of their training, depending on the degree they consider fellows as junior faculty involved in teaching and modeling patient care.(More)
To study the possible effects of epidural anesthesia on the Doppler velocimetry of the fetal umbilical and maternal uterine arteries, 15 normal term parturients were examined during active labor. Each Doppler study, conducted over 90 minutes after a 500-mL intravenous volume pre-load, was divided into three phases: 30 minutes of pre-anesthetic control, 30(More)
A review of the grading process used in an obstetrics and gynecology clerkship prompted an analysis of physician ratings of student clinical performance. The study assessed the following: 1) the degree to which raters distinguished among six categories of performance, 2) the concordance among raters in terms of evaluation criteria used, 3) the degree of(More)
The calculation of sample size should be an integral part of the planning stages of all research projects to avoid wasting time, money, and valuable resources. The necessary information for sample size calculations includes the alpha (type I) error level, the beta (type II) error, delta (or the difference you would like to be able to detect), and, for(More)
This study considers primary dysmenorrhea from a biopsychosocial perspective in examining the relationship between physical exercise and menstrual pain. Despite widespread claims of the benefits of exercise for perimenstrual symptoms, the evidence seems weak. Stronger evidence indicates that exercise helps relieve stress and elevates mood and that stress(More)
