Computed Tomography-Guided Placement of Sacral Electrodes.

BACKGROUND: The current approach to performing sacral neuromodulation consists of a two-stage procedure, the first of which includes insertion of the sacral electrode under fluoroscopic visualization of the S3 foramen. Alternatively, in certain situations computed tomography (CT)-guided insertion can be used. OBJECTIVES: To evaluate the use of CT in cases of reinsertion of the electrode due to infection, dislocation, or rupture. METHODS: Medical records of patients who underwent neuromodulation device reinsertion between 2005 and 2016 for fecal incontinence were reviewed. Study outcomes included procedure course, successful placement, and long-term treatment success. RESULTS: During the study period, we inserted a neuromodulation device in 67 patients. A CT-guided insertion of a sacral electrode was performed in 10 patients. In nine patients, the insertion and the final location of the electrode were successful. In one patient, the electrode migrated upward due to a malformation of the S3 foramen on both sides and had to be placed in S4. In a mean follow-up of 68.4 ± 30.0 months following the re-insertion, there was a significant reduction in the number of incontinence episodes per day (P < 0.001) and the number of pads used per day (P = 0.002). CONCLUSIONS: CT-guided insertion of a sacral electrode is a safe and promising option, especially in recurrent and or selected cases.

Reduced fetal movements at term in singleton low risk pregnancies-Is there an association with placental histopathological findings?

INTRODUCTION: Maternal perception of fetal movements has long been considered an indicator of fetal well-being. A sudden decrease in the number of fetal movements is suggestive of fetal compromise. We aimed to determine whether the maternal perception of reduced fetal movements (RFM) is associated with placental pathological lesions in a low-risk term population. MATERIAL AND METHODS: Our study was a case-control study that was performed in a single university center. Placental histopathology, maternal demographics, labor characteristics, and neonatal outcomes of term, singleton pregnancies with maternal perception of RFM during the 2 weeks prior to delivery were collected. To isolate the effect of RFM on placental pathology, we excluded cases complicated by preterm birth, hypertensive disorders, diabetes mellitus, small-for-gestational-age and congenital/genetic anomalies. We compared pregnancy outcomes and placental pathology between the RFM group and a control group matched for gestational age and mode of delivery. Placental lesions were classified according to the "Amsterdam" criteria. Composite adverse neonatal outcome was defined as one or more of the following: sepsis, transfusion, hypoglycemia, phototherapy, respiratory morbidity, cerebral morbidity, necrotizing enterocolitis and fetal/neonatal death. Multivariable regression analysis was performed to identify independent associations with adverse neonatal outcome. RESULTS: We included patients who gave birth from January 2008 until May 2019. The study group included 203 term pregnancies with RFM during the 2 weeks prior to delivery, which was matched with 203 controls. The RFM group was characterized by a higher rate of placental weight <10th percentile (22.6% vs. 3.9%, P < .001), a higher rate of maternal vascular malperfusion lesions (30.5% vs. 18.7%, P = .007) and lesions of maternal inflammatory response (43.3% vs. 29.5%, P = .005). At delivery, the RFM group had higher rates of cesarean delivery due to non-reassuring fetal heart rate monitoring (P = .01), 5-minute Apgar score ≤7 (P = .03), neonatal intensive care unit admissions (P < .001) and composite adverse neonatal outcomes (P = .007). Using multivariable analysis, RFM (adjusted odds ratio [aOR] 1.7, 95% confidence interval [CI] 1.1-4.8), and placental maternal vascular malperfusion lesions (aOR 1.2, 95% CI 1.0-2.9) were independently associated with adverse neonatal outcome. CONCLUSIONS: After excluding important placental-related morbidities, RFM was associated with a higher rate of placental weight <10th percentile and placental maternal vascular malperfusion lesions vs. controls. This study suggests a placental involvement in the association between RFM at term and adverse pregnancy outcomes.

Preterm uterine contractions ultimately delivered at term: safe but not out of danger.

OBJECTIVES: Patients with pregnancies complicated with premature uterine contractions (PMC), but delivered at term are considered as false preterm labor (PTL), and represent a common obstetric complication. We aimed to assess obstetric and neonatal outcomes of pregnancies complicated with PMC, but delivered at term, as compared to term normal pregnancies. STUDY DESIGN: Obstetric, maternal and neonatal outcomes of singleton pregnancies complicated with PMC between 24-33(6)/7 weeks (PMC group), necessitating hospitalization and treatment with tocolytics and/or steroids, during 2009-2014, were reviewed. The study group included only cases who eventually delivered ≥37 weeks, which were compared to a control group of subsequent term singleton deliveries who had not experienced PMC during pregnancy. Neonatal adverse composite outcome included: phototherapy, RDS, sepsis, blood transfusion, cerebral injury, NICU admission. RESULTS: The PMC group (n=497) was characterized by higher rates of nulliparity (p=0.002), infertility treatments (p=0.02), and polyhydramnios (p<0.001), as compared to controls (n=497). Labor was characterized by higher rates of instrumental deliveries (p=0.03), non-reassuring fetal heart rate tracings (p<0.001) prolonged third stage of labor (p=0.04), and increased rate of post-partum maternal anemia (Hb<8g/dL) p=0.004, in the PMC group as compared to controls. Neonates in the PMC groups had lower birth weights compared to controls, 3149g±429 vs. 3318g±1.1, p<0.001, respectively. By logistic regression analysis, PMC during pregnancy was independently associated with neonatal birth-weight <3rd percentile (adjusted OR 4.6, 95% CI 1.5-13.7). CONCLUSIONS: Pregnancies complicated with PMC, even-though delivered at term, entail adverse obstetric and neonatal outcomes, and may warrant continued high risk follow up.
