Menopause is associated with increased cardiovascular risk factors. We designed this study to compare common carotid artery intima media thickness (IMT) and homocysteine level between women who had natural menopause and those who had surgical menopause and to correlate IMT, bone mineral density (BMD), and homocysteine level with time since menopause. Ninety healthy postmenopausal women aged 50 to 78 years who were not on hormone therapy (45 women who did not have a prior hysterectomy or oophorectomy and 45 women who had undergone hysterectomy with bilateral oophorectomy) were included in the study. B-mode ultrasonography of the carotid artery, BMD, and serum homocysteine level analysis were completed to evaluate the relationship between type of menopause, time since menopause, and subclinical atherosclerosis. Mean ± SD carotid artery IMT measurements were 0.72 ± 0.002 mm among women experiencing natural menopause and 0.88 ± 0.003 mm among women having bilateral oophorectomy (P = 0.002). After adjusting for time since menopause and age, the mean IMT also differed between the two groups: 0.76 ± 0.003 mm in the natural menopause group and 0.84 ± 0.003 mm in the bilateral oophorectomy group (P = 0.038). The age-adjusted carotid IMT was significantly positively associated with years since menopause (P = 0.001). Mean homocysteine measurements were 10.3 ± 5 μmol/L among women experiencing natural menopause and 9.1 ± 4 μmol/L among women who had bilateral oophorectomy (P = 0.216). Age-adjusted femur total, trochanter, and shaft BMDs were significantly lower in the surgical menopause group (P = 0.041, P = 0.034, and P = 0.046, respectively). Oophorectomy before natural menopause increases IMT but not homocysteine levels independent of age and time since menopause and is associated with lower BMD values after adjustment for age.

Subchorionic haemorrhage in the 1st trimester of pregnancy can be seen in some patients and the significance of it is controversial. In this study, subchorionic haemorrhage was found to be significantly associated with increased risk of miscarriage and IUGR. On the other hand, we did not see a significant relation between pre-term labour and subchorionic haemorrhage. We hope these findings will help clinicians in their practice about pregnancy follow-up.

Background: To determine the impact of cervical length (CL) on the clinical outcome of patients undergoing peripartum hysterectomy due to placenta previa/percreta. Objective: To assess the association of CL with clinical outcomes in such patients. Methods: We analyzed the data of patients who were diagnosed with anterior placenta previa/percreta prenatally and subsequently underwent peripartum hysterectomy at our tertiary care institution between 2004 and 2014. The sonographic images and measurements of CL were obtained from prospectively collected database. The duration of operation, units of blood products transfused, and length of stay in the hospital were recorded. Patients were stratified according to CL, and receiver-operating characteristics curves were used to determine the cut-off length for identification of patients at high risk of intra-operative difficulty. Results: Sixty-one patients were included in this study. Number of packages of ES were correlated with the the duration of operation (r = 0.666, p < 0.001) and the CL (−0.793, p < 0.001). Number of packages of fresh frozen plasma was significantly correlated with the CL (−0.642, p < 0.001) and the duration of operation (r = 0.606, p < 0.001). Gestational age (AUC = 0.683, p = 0.014) and the CL (AUC = 0.980, p < 0.014) were significant predictors for the number of ES transfused > 4 packages. The cut-off value of four packages was determined according to the median level of packages transfused. Optimal cut-off value for the CL to predict transfusion ≤ 4 packages was 20.5 with 93% sensitivity and the 99% specificity. Conclusions: Short cervix appears to be a cause of difficulty in placenta previa/percreta operations. CL may also help in determining the timing of delivery in placenta percreta patients.
