A comparison of ultrasonographically detected cervical changes in response to transfundal pressure, coughing, and standing in predicting cervical incompetence

Article Abstract:

Applying pressure across the cervix appears to provide a more active assessment of cervical competence than standing or coughing does. Vaginal and cervical measurements were performed on 89 at-risk pregnant women before and after stress tests involving coughing, standing, and transfundal pressure. These examinations were done twice in conjunction with ultrasound scans between 15 and 24 weeks of pregnancy. The greatest change in vaginal and cervical measurements occurred after transfundal pressure was applied. Women who experienced these physically measured changes after transfundal pressure were significantly more likely to also have observable changes on ultrasound.

Placenta previa in singleton and twin births in the United States, 1989 through 1998: a comparison of risk factor profiles and associated conditions

Article Abstract:

Risk factors for placenta previa include a twin pregnancy, older age, a history of several previous pregnancies, and smoking. Placenta previa is a complication of pregnancy in which the placenta blocks the opening from the uterus into the vagina. It can cause bleeding, fetal death, premature birth, and low birth weight.

Assessing genetic risk: comparison between the referring obstetrician and genetic counselor

Article Abstract:

Referring pregnant women with risk factors for a genetic disorder to a genetic counselor can improve the detection of genetic risk factors. Of 145 pregnant women who were referred by an obstetrician to a genetic counselor, 55 were found to have additional genetic risk factors that the obstetrician overlooked.
