STUDY OBJECTIVE:To compare operative time in women stratified by body mass index (BMI) undergoing robotic-assisted sacrocolpopexy (RASC). Secondary objectives included characterizing perioperative characteristics and reoperation rates. DESIGN:Retrospective cohort study (Canadian Task Force classification II-2). SETTING:University-affiliated teaching hospital. PATIENTS:One hundred seventy-nine consecutive patients who underwent RASC by a single surgeon from 2009 through 2013. INTERVENTIONS:RASC. MEASUREMENTS AND MAIN RESULTS:). Overweight patients were significantly older, more parous, more frequently postmenopausal, and more frequently underwent concomitant salpingo-oophorectomy. Median operative times were 202, 206, and 216 minutes in the normal-weight, overweight, and obese groups, respectively (p = .53). CONCLUSION:Obese women undergoing RASC have similar operative time and procedural characteristics as normal-weight and overweight patients. Longer term outcomes are needed to ensure comparable surgical and anatomic success.

OBJECTIVE: The prenatal detection rate of isolated fetal limb abnormalities ranges from 4 to 29.5%. Our aim was to determine the accuracy of a detailed ultrasound protocol in detecting isolated fetal limb abnormalities Methods: This is a retrospective study of infants born at our institution with isolated limb defects from 2009 to 2014. Antepartum and postpartum records were reviewed for genetic testing results. We routinely image both upper and lower extremities, including all long bones, hands, feet, fingers and toes. Posturing, muscular tone and movement are also noted. RESULTS: During the study period, there were 52 neonates born with isolated fetal limb abnormalities who had received a fetal anatomic survey in our ultrasound unit and 15 930 sonograms performed with normal findings; 36 out of the 52 had been prenatally diagnosed (detection rate 69%). The specificity of the protocol was 100% as there were no false positive cases, the positive predictive value was 100% and negative predictive value 99.8%. Forty-three of 52 neonates had normal genetic testing either prenatally or postnatally; 9 neonates did not undergo genetic testing. The average additional time required for this detailed protocol was <5 min for second trimester sonogram. CONCLUSION: A minimal investment in time for detailed evaluation of fetal limbs more than doubles the previously reported prenatal detection rate.

BACKGROUND:Placental abruption traditionally is defined as the premature separation of the implanted placenta before the delivery of the fetus. The existing clinical criteria of severity rely exclusively on fetal (fetal distress or fetal death) and maternal complications without consideration of neonatal or preterm delivery-related complications. However, two-thirds of abruption cases are accompanied by fetal or neonatal complications, including preterm delivery. A clinically meaningful classification for abruption therefore should include not only maternal complications but also adverse fetal and neonatal outcomes that include intrauterine growth restriction and preterm delivery. OBJECTIVES/OBJECTIVE:The purpose of this study was to define severe placental abruption and to compare serious maternal morbidity profiles of such cases with all other cases of abruption (ie, mild abruption) and nonabruption cases. STUDY DESIGN/METHODS:We performed a retrospective cohort analysis using the Premier database of hospitalizations that resulted in singleton births in the United States between 2006 and 2012 (n = 27,796,465). Severe abruption was defined as abruption accompanied by at least 1 of the following events: maternal (disseminated intravascular coagulation, hypovolemic shock, blood transfusion, hysterectomy, renal failure, or in-hospital death), fetal (nonreassuring fetal status, intrauterine growth restriction, or fetal death), or neonatal (neonatal death, preterm delivery or small for gestational age) complications. Abruption cases that did not qualify as being severe were classified as mild abruption cases. The morbidity profile included amniotic fluid embolism, pulmonary edema, acute respiratory or heart failure, acute myocardial infarction, cardiomyopathy, puerperal cerebrovascular disorders, or coma. Associations were expressed as rate ratios with 95% confidence intervals that were derived from fitting log-linear Poisson regression models. RESULTS:The overall prevalence rate of abruption was 9.6 per 1000, of which two-thirds of cases were classified as being severe (6.5 per 1000). Serious maternal complications occurred in 15.4, 33.3, and 141.7 per 10,000 among nonabruption cases and mild and severe abruption cases, respectively. In comparison with no abruption, the rate ratio for serious maternal complications were 1.52 (95% confidence interval, 1.35-1.72) and 4.29 (95% confidence interval, 4.11-4.47) in women with mild and severe placental abruption, respectively. Rate ratios for the individual complications were 2- to 7-fold higher among severe abruption cases. Furthermore, the rate ratios for serious maternal complications among severe abruption cases compared with mild abruption cases was 3.47 (95% confidence interval, 3.05-3.95). This association was considerably stronger for virtually all maternal complications among cases with severe abruption compared with mild abruption. Annual rates of mild and severe abruption were fairly constant during the study period. Although the maternal complication rate among non-abruption births was stable from 2006-2012, the rate of complications among mild abruption cases dropped from 2006-2008 and then leveled off thereafter. In contrast, the rate of serious complications among severe abruption cases remained fairly stable from 2006-2010 and increased sharply thereafter. CONCLUSIONS:Severe abruption was associated with a distinctively higher morbidity risk profile compared with the other 2 groups. The clinical characteristics and morbidity profile of mild abruption were more similar to those of women without an abruption. These findings suggest that the definition of severe placental abruption based on the proposed specific criteria is clinically relevant and may facilitate epidemiologic and genetic research.

Background:Cesarean scar ectopic pregnancies (CSPs) are becoming more prevalent and can have an extremely poor prognosis, with high morbidity and mortality. Management guidelines for patients desiring conservative treatment should be established to improve outcomes. Case:A 33-year-old woman with a conservatively managed CSP now in the second trimester presented from an outside institution. After thorough counseling regarding potential maternal morbidity and extreme prematurity in the newborn based on clinical findings of progressive cervical shortening and vaginal spotting with a significant drop in hemoglobin, she abandoned conservative therapy and underwent a hysterectomy with the previable fetus in situ. Conclusion:As pregnancy progresses, danger to the mother and fetus can become severe and imminent. Progressive cervical shortening may be associated with much more significant bleeding than evidenced by spotting, indicating the importance of using cervical shortening in abandonment of conservative management to reduce impending morbidity and mortality.
