Castor oil for labor initiation in women with a previous cesarean section: a double-blind randomized study.

Objective: To evaluate the efficacy of castor oil in initiation of labor in women who had one previous cesarean section. This study was conducted as a trial to increase the rate of vaginal birth after cesarean (VBAC) and decrease the rate of elective repeated cesarean section (ERCS).Methods: A double-blinded randomized controlled study was conducted in an Egyptian University Hospital from July 2019 to July 2020. The participants were 70 pregnant women who had one previous cesarean section, singleton pregnancy in cephalic presentation, with a Bishop score ≤6 attempting to perform a trial of labor. Sixty mL castor oil was administered to group A and 60 mL sunflower oil was administered to group B (as a placebo) for initiation of labor at the start of week 39. Primary outcomes were the percentage of women entering the active phase of labor within 24 h after receiving castor oil or placebo and the number of successful VBAC deliveries.Results: Labor started in 16 patients (45.7%) within 24 h in the castor oil group and in 3 patients in the placebo group (8.5%), while the rate of successful VBAC was 65.7% (23 patients) in the castor oil group and 48.5% (17 patients) in the placebo group.Conclusion: Castor oil appears to be an effective, low-cost, and non-harmful method for the initiation of labor in patients with a previous cesarean section.

Three-dimensional ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.

BACKGROUND: Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. METHODS: This cross-sectional study included 78 premenopausal women with abnormal uterine bleeding scheduled for hysteroscopy and endometrial curettage. The endometrial thickness (ET), uterine artery pulsatility index (PI) and resistance index (RI), and endometrial volume (EV) and 3D power Doppler vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were measured and compared with hysteroscopic and histopathologic findings. RESULTS: The ET (P <0.001), EV (P <0.001), and endometrial VI (P <0.001) and VFI (P = 0.043) were significantly increased in patients with atypical endometrial hyperplasia and endometrial carcinoma (n = 10) than those with benign endometrium (n = 68); whereas, the uterine artery PI and RI and endometrial FI were not significantly different between the two groups. The best marker for discrimination between benign and malignant endometrium was the VI with an area under the ROC curve of 0.88 at a cutoff value of 0.81%. CONCLUSION: 3D ultrasonography and power Doppler, especially endometrial VI, may be useful for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.

Periconceptional risk factors of spina bifida among Egyptian population: a case-control study.

OBJECTIVE: To study the preconceptual & early conceptional risk factors predisposing to the development of spina bifida (SB) among Egyptian population. STUDY DESIGN: The study involved 197 pregnant women undergoing fetal anatomy scan; 97 women proved to have fetal SB and 100 women with normal fetuses as a control group. The control group was recruited randomly in the same period from patients undergoing anatomical scan. Risk factors that might lead to SB were investigated including maternal age, gravidity, parity, residence, history of diabetes mellitus or drug intake, smoking, infections, exposure to X-ray, history of congenital anomalies in other offspring, parental consanguinity, positive family history, and folate supplementations. RESULTS: SB affected the lumbo-sacral region in the majority of cases (89.7%). It was associated with hydrocephalus in 66 cases (68%), polyhydramnios in 12 cases (12.4%). The SB group showed significantly higher parity (p = 0.005), more frequent history of drug intake (p < 0.001), higher frequency of infection with CMV (p = 0.004), and HSV (p = 0.013) and less proportion of folate supplementation (p < 0.001). CONCLUSION: The rate of SB in the tested group was five per 1000. Risk factors were lack of folate supplementation and history of antiepileptic drugs intake.
