Incidence of Abnormal Findings During Pelvic Examinations in Women Aged 21-35 Years.

To describe the incidence of abnormal gynecologic examination findings in asymptomatic compared with symptomatic patients during preventive visits, we conducted a retrospective study of 1,121 visits for patients between the ages of 21 and 35 years from January 2017 to March 2017. Only 1.2% (95% CI, 0.5%,1.9%) of asymptomatic patients had abnormal findings on pelvic examination, compared with 32.4% (95% CI, 27.0%, 37.8%) of those with symptoms ( P ≤.001). In symptomatic patients, the most common symptoms were vaginal discharge (25.1%), pelvic pain (16.4%), and vaginal bleeding (15.7%). In asymptomatic patients, the most common findings were bacterial vaginosis and Candida infection. Asymptomatic patients presenting for a routine preventive visit have low rates of abnormalities detected on examination, and routine pelvic examinations should be re-considered.

Predicting Uterine Rupture Risk Using Lower Uterine Segment Measurement During Pregnancy With Cesarean History: How Reliable Is It? A Review.

Importance: Uterine rupture during labor is a calamitous event that can result in maternal/neonatal morbidity/mortality. Lower uterine segment (LUS) thickness measurement is a proposed method to determine the risk factor of uterine rupture in women undergoing trial of labor after cesarean. Does this measurement predict uterine rupture risk? Objectives: This review examines current evidence to determine if a thin LUS ultrasound diagnosis during pregnancy with prior cesarean delivery(s) can reliably predict uterine rupture risk while attempting vaginal birth after cesarean (VBAC). Evidence Acquisition: Electronic databases (PubMed and CINAHL) were searched with one limitation of abstracts in English. Search terms used were "lower uterine segment" AND "risk(s)" AND "rupture" OR "dehiscence. Results: After reviewing 164 identified articles, 15 were used in this review. Of the studies including LUS thickness measurement, notable differences were found: gestational age at time of measurement, full thickness measurement versus myometrial thickness, number of sonographers involved, ultrasound technique (transabdominal vs transvaginal), and blinding. Other factors influencing LUS thickness include fetal weight, amniotic fluid volume, and gestational age. The most recent systematic review and meta-analysis suggests that an LUS > 3.65 mm should be safe for a VBAC, 2-3.65 mm is probably safe, and <2 mm identifies a patient at higher risk for uterine rupture/dehiscence. Conclusions: Study heterogeneity, absence of an agreed upon thickness threshold, poor correlation between ultrasound and MRI measurements, or physical cesarean measurements currently make VBAC uterine rupture risk prediction uncertain. Relevance: Our aim is to analyze existing literature to determine if evidence supports LUS measurement in women undergoing VBAC after cesarean to determine risk of uterine rupture.

Incidence of Gestational Diabetes Diagnosed on the 100-G Glucose Tolerance Test in Pregnancies with a 50-G Glucose Challenge Test Result of 200 mg/dL or Greater.

OBJECTIVE: This study aimed to assess the positive predictive value (PPV) of a 1-hour, 50-g glucose challenge test (GCT) result ≥200 mg/dL for the diagnosis of gestational diabetes mellitus (GDM) on a 3-hour, 100-g glucose tolerance test (GTT). STUDY DESIGN: Pregnancies between 2008 and 2016 with a GCT result ≥200 mg/dL were identified retrospectively. GCT and GTT dates and results, demographics, and working due date (EDD) were extracted. Gestational age at testing was calculated from test date and EDD. As some clinicians presumptively diagnose GDM in such cases, if a GTT result was not available, clinic notes were reviewed to determine whether a GTT was ordered. Positive predictive values (PPV) were calculated at GCT cut-offs at and beyond 200 mg/dL. Subgroups were compared including early GCT (<16 weeks) versus routine GCT (24-28 weeks), GTT result normal versus GTT diagnostic of GDM, and GTT ordered versus GTT not ordered. Rates of use of medication for glycemic control were assessed among these groups. RESULTS: Of 236 pregnant women with a GCT result ≥200 mg/dL, 115 (48%) GTT was ordered for 115 (49%), whereas 123 (52%) were managed as presumed GDM. Of 100 (87%) who completed the test, 81 (81%) were diagnosed with GDM with a median intertest interval of 14 days. No statistically significant differences were found between groups stratified by GTT result. Use of rates of metformin, glyburide, and insulin were similar between those diagnosed with GDM by GTT and those diagnosed with GDM by GCT alone. CONCLUSION: A GCT result of ≥200 mg/dL has a PPV of 81% for diagnosis of GDM by GTT in a contemporary U.S. population, with a median intertest interval of 14 days between GCT and GTT. However, those diagnosed by GCT alone were as likely as those diagnosed by GTT to require medication for glycemic control, including insulin, suggesting that requiring a GTT may result in underdiagnosis and delayed treatment of GDM. KEY POINTS: · A 50-g GCT result of 200 mg/dL or greater has a PPV of 81% for GDM on the 100 g GTT.. · Patients diagnosed with GDM by GCT alone were as likely to require insulin as those diagnosed by GTT.. · 81% of patients diagnosed with GDM on the GTT completed their GTT at least 1 week after the GCT, thus requiring GTT in this population may lead to unnecessary delays in care..

Deciding on route of delivery for obese women with a prior cesarean delivery.

OBJECTIVES: This study was undertaken to estimate the vaginal birth after cesarean (VBAC) success rate, compare rates of infections in women attempting VBAC and those undergoing planned repeat cesarean, and compare the cost of these two plans of care for obese women. STUDY DESIGN: We performed a historical cohort analysis of singleton deliveries at >/=36 weeks' gestation in women with a body mass index 40 or greater and one prior cesarean delivery. Outcomes included rates of VBAC success and puerperal infections and mean cost of care. RESULTS: The cohort consisted of 122 mother-infant pairs, 61 each in the VBAC and cesarean groups. In the VBAC group, 57% (95% CI 45-70) of women were delivered vaginally. The VBAC group had higher rates of chorioamnionitis (13.1% vs 1.6%, P=.02), endometritis (6.6% vs 0%, P=.06), and composite puerperal infection (24.6% vs 8.2%, P=.01). Mean cost of care was similar for mothers ($4439 vs $4427, P=.95), infants ($1241 vs $1422, P=.49), and mother-infant pairs ($5680 vs $5851, P=.64). CONCLUSION: Compared with planned cesarean delivery, VBAC trials in obese women are three times as likely to be complicated by infection and do not result in reduced costs.
