BACKGROUND: Breech presentation is associated with increased risk. External cephalic version (ECV) has been successful in decreasing the incidence of intrapartum breech presentation. CASE: Funic presentation occurred as a complication of successful ECV. CONCLUSION: The wide-spread use of version calls for increased surveillance for adverse sequelae. At the completion of ECV, ultrasound analysis, pelvic examination and fetal heart rate monitoring are appropriate to exclude serious cord complications.
OBJECTIVE: To evaluate the utility of the prenatal three-generation pedigree in assessment of the obstetric patient's primary medical risks. STUDY DESIGN: In a case series, 250 charts of patients referred for amniocentesis on the basis of advanced maternal age were reviewed for a significant genetic risk of a primary care disorder. RESULTS: A total of 40 patients (16%) were at significantly increased risk for a primary care disorder. Thirty-eight patients (15.2%) were at increased risk for medical conditions for which early screening, detection and/or intervention are established. CONCLUSION: For the advanced maternal age population, formal genetic risk assessment performed prior to amniocentesis can be beneficial in primary care risk assessment.
We are engaged in studying the process of human birth by developing a computer-based dynamic model that can be adapted to specific birth scenarios. The individual characteristics of a given pregnant woman and fetus, embedded in their clinical measurements and CT and MRI images, are captured in the model. One can thereby predict adverse events that might happen during labor and delivery. Based on our findings from a preliminary design and execution of this model, we believe it holds great promise as an accurate, cost-effective diagnostic and teaching tool that will help predict conditions during individual labor scenarios that might cause traumatic birth injuries, and thereby enable us to make the most informed clinical decisions possible.
A vital component of selective protocols in term breech presentation management is exclusion of the gravida with borderline pelvic dimensions. Computed tomographic (CT) pelvimetry was employed to evaluate potential candidates for a trial of labor with a breech fetus at term. Thirty-seven of 39 women who underwent labor after this selection had a successful assisted vaginal breech delivery. Adequate pelvic dimensions by CT pelvimetry reliably predicted a safe vaginal delivery in patients managed within a standard breech protocol.

A case of relapsing polychondritis is reported. This woman was delivered of two normal infants at term.
In many cases of breech presentation, a trial of labor is practical and safe among carefully selected parturients. Anesthesia and full neonatal support should be available. Described is the protocol in use at several large institutions that maintain a Cesarean rate for breech presentation in the 60 to 70 per cent range which is approximately 25 per cent lower than the national rate. The development of this protocol as well as its highlights in clinical application are described and highlighted in this report.

We have reviewed several different groups of common clinical problems with an eye toward their effects on FHR tracings. Although argument exists in the literature concerning the universal applicability of continuous EFM, most authors agree that continuous EFM is desirable, if not imperative, within these subgroups. Schifrin said, "It appears that potential benefits accrue when EFM and scalp sampling are employed with understanding and adequate training." With appropriate training, EFM and pH analysis can help the clinician to quickly and accurately assess fetal condition and to make necessary decisions regarding labor and delivery. The interpretation of fetal monitoring patterns necessitates consideration of gestational age and maternal condition as a starting point in analysis. The many other components of fetal-maternal interactions that occur with labor and delivery can be assessed satisfactorily only in this light.
Two cases of severe fetal hemorrhage were associated with maternal anticonvulsants. One patient required cesarean section for intractable fetal bleeding following scalp sampling, while the other was managed with local hemostatic measures.
X-ray evaluation of the pelvis plays a pivotal role in selecting term breech presentation for a possible trial of labor. Even minimal degrees of disproportion may have disastrous consequences for the aftercoming head. Our evaluation of x-ray pelvimetry by computerized tomography scanning suggests it is probably more accurate than conventional methods, with a concomitant decrease in fetal x-ray exposure.
