ObjectiveTo assess the effectiveness of prophylactic bilateral uterine artery ligation (BUAL) in reducing the incidence of postpartum hemorrhage (PPH) during cesarean delivery among women at risk of uterine atony.MethodsA randomized clinical trial at Cairo University Maternity Hospital, Egypt, from December 2017 to December 2018. Women at risk of uterine atony undergoing scheduled or emergency cesarean were randomized to two groups. In the BUAL group, women underwent BUAL before placental delivery; in the control group, women had cesarean delivery without BUAL. The primary outcome was the estimated blood loss during cesarean.ResultsIntraoperative blood loss during cesarean was significantly lower in the BUAL group than in the control group (523.4 ± 41.0 vs 619.6 ± 36.1 mL; P=0.003). Blood loss in the first 6 hours after cesarean was also significantly lower in the BUAL group than in the control group (246.1 ± 21.4 vs 326.1 ± 18.5 mL; P=0.006). There was no difference in operative time between the two groups (52.1 ± 6.1 vs 52.2 ± 6.8, P=0.880).ConclusionBUAL during cesarean was found to be an effective method for decreasing blood loss during and after cesarean delivery among women at risk of uterine atony and subsequent PPH.ClinicalTrials.gov: NCT03591679

Aim: To evaluate clinically the color stability and patient satisfaction of polished versus glazed lithium disilicate glass ceramic restorations. Methodology: Twenty full coverage crowns were fabricated from IPS e. max press in the posterior area. The patients were randomly divided into two equal groups according to the applied crown surface treatment. Group 1 (control group) 10 glazed crowns and Group 2 (intervention group) 10 polished crowns. ΔE was measured using Vita easyshade and patient satisfaction was evaluated through Visual Analogue Scale (VAS), immediately after cementation and every two months for one year. Data were analyzed using two-way ANOVA and t-test. P ≤ 0.05 was considered statistically significant. Results: The results showed that the polishing technique had a statistically significant mean ΔE than glazing but both were clinically acceptable. Regarding the follow up period results showed that time had no statistically significant effect on mean ΔE values. There was also no statistically significant difference in patient satisfaction within each technique and at the different follow up times. Conclusion: Although polishing showed higher color change than glazing, it was clinically acceptable. Therefor polishing can be recommended as an alternative to glazing for IPS e.max crowns.
