Efficacy of Intravenous Tranexamic Acid in Reducing Blood Loss after Elective Cesarean Section: A Prospective, Randomized, Double-Blind, Placebo-Controlled Study

We sought to determine the efficacy and safety of tranexamic acid (TA) in reducing blood loss during elective cesarean section (CS). We performed a randomized, double-blind, placebo-controlled study of 660 women who underwent elective CS. The patients were randomly selected to receive an intravenous infusion of either TA (1 g/10 mL in 20 mL of 5% glucose; N = 330) or 30 mL 5% glucose prior to surgery. The primary outcome was the estimated blood loss following CS. No demographic difference was observed between groups. The mean estimated blood loss was significantly lower in women treated with TA compared with women in the placebo group (499.9 ± 206.4 mL versus 600.7 ± 215.7 mL, respectively; P < 0.001), and the proportion of women in the TA group who had an estimated blood loss >1000 mL was significantly lower than in the placebo group (7 [2.1%] versus 19 [5.8%], respectively; relative risk [RR] 2.7; 95% confidence interval [CI] 1.1 to 6.3; P < 0.03). Furthermore, more women in the placebo group than in the TA group required additional uterotonic agents (48 [14.5%] versus 28 [8.5%], respectively; RR 1.7; 95% CI 1.1 to 2.6; P = 0.02). Maternal and neonatal outcomes did not differ significantly. TA significantly reduced bleeding during CS, the percentage of patients with blood loss >1000 mL, and the need for additional uterotonic agents. Furthermore, the incidence of thromboembolic events did not increase. Our results suggest that TA can be used safely and effectively to reduce CS bleeding.

Which type of mid-urethral sling procedure should be chosen for treatment of stress urinary incontinance with intrinsic sphincter deficiency? Tension-free vaginal tape or transobturator tape

Objective. To compare tension‐free vaginal tape (TVT) and transobturator tape (TOT) for surgical treatment of stress urinary incontinence (SUI) with intrinsic sphincter deficiency. Design. Retrospective study. Setting. Gynecology department, Bakirkoy Women and Childrens’ Hospital, Istanbul. Sample. Three hundred women urodynamically diagnosed with stress incontinence with intrinsic sphincter deficiency underwent synthetic mid‐urethral sling procedures (TVT = 180, TOT = 120). Methods. Before the operation, a complete medical history was taken and a gynecologic examination was performed. Subjects with detrusor overactivity or previous sling surgery were excluded. Clinical checkups were conducted at 3, 6, and 12 months, and then annually. Main outcome measures. Intraoperative complications, postoperative complications, and subjective cure rates. Results. There were no significant differences in demographics between the TVT and TOT groups: mean age, parity, body mass index, menopausal status, and hormone replacement therapy. At a mean follow‐up of 31.2±9.1 (range 12–46) months, the overall cure rates were 78.3% for TVT and 52.5% TOT (p<0.0001). The risk of treatment failure in women who received TOT was 4.9 times higher than in women who underwent TVT. There were no significant differences in perioperative and postoperative complication rates between the two groups. Conclusion. TVT appears to be the preferable surgical option for the treatment of SUI with intrinsic sphincter deficiency.

Can Intravenous Injection of Tranexamic Acid Be Used in Routine Practice with Active Management of the Third Stage of Labor in Vaginal Delivery? A Randomized Controlled Study

OBJECTIVE To estimate the effects of adding intravenous tranexamic acid (TA) to the standard active management of third-stage labor to reduce vaginal blood loss during the third and fourth stages of labor. STUDY DESIGN A prospective, double-blind, equivalence randomized, controlled study was performed. Women were randomly allocated to receive an intravenous infusion of TA (experimental group, n = 228) or 5% glucose (placebo group, n = 226) at delivery of the anterior shoulder. Active management of the third stage of labor, which includes prophylactic injection of 10 IU of oxytocin within 2 minutes of birth, early clamping of the umbilical cord, and controlled cord traction following delivery, was used in both groups. The primary outcome was mean blood loss during the third and fourth stages of labor. RESULTS Mean estimated blood loss at the third and fourth stages of labor was significantly lower in the experimental group than that in the placebo group (261.5 ± 146.8 mL versus 349.98 ± 188.85 mL, respectively; p < 0.001). The frequency of postpartum hemorrhage > 500 mL was also lower in the experimental group (4, 1.8%) compared with that in the placebo controls (15, [6.8%]; relative risk, 3.76; 95% confidence interval, 1.27 to 11.15; p = 0.01). No episode of thrombosis occurred in the women who received TA. CONCLUSIONS The use of TA with standard active management of the third stage of labor reduced postpartum blood loss, and no increase in the incidence of thromboembolic events was observed.

First trimester diagnosis of sirenomelia: a case report and review of the literature

Sirenomelia sequence is a rare lethal pattern of congenital anomalies characterized by a number of hallmark skeletal anomalies, including fusion of the lower extremities or a single lower limb, bilateral renal agenesis or dysgenesis with absent or hypoplastic renal arteries, oligohydramnios, and the presence of aberrant vasculature. The etiology is still controversial. Prognosis is very poor, with the babies being stillborn or succumbing soon after birth. In the second trimester, oligohydramnios due to renal agenesis makes the diagnosis of sirenomelia difficult. Conversely, in the first trimester, the amniotic fluid volume is usually normal, unrelated to the fetal urine production. Therefore, a first-trimester or early second trimester anatomic survey of the fetus is proposed as preferable and more accurate for the diagnosis of this rare anomaly. In this article, we report a case of sirenomelia detected by two- and three-dimensional ultrasound in the 11th week of gestation and the associated literature is discussed.

Prenatal diagnosis of imperforate hymen with hydrometrocolpos

Imperforate hymen is one of the most simple and most common anomalies in the female genital organs, occurring in 0.1% of girls born at term. Some are recognized because of mucocolpos at birth, but the diagnosis is usually not detected before puberty. Rarely, obstetric sonography may prenatally detect imperforate hymen due to presentation of hydrocolpos or hydrometrocolpos in the fetus if fetal cervical and vaginal secretions accumulate in response to circulating maternal estrogens. Nonetheless, reports of prenatal ultrasound diagnosis of hydrometrocolpos are still very rare. In this article we report a prenatally diagnosed of imperforate hymen with hydrometrocolpos.

Postmenopausal tuberculosis endometritis.

Tuberculosis remains a global health problem, primarily in developing countries with inadequate health services. A significant portion of tuberculosis in these settings is extrapulmonary, including tuberculosis of the genitourinary tract. Patients with genital tuberculosis are usually young women detected during work up for infertility. After menopause, tuberculosis of the endometrium is a rare possibility probably because of the decreased vascularity of the tissues. We present a case of endometrial tuberculosis with postmenopausal vaginal bleeding.

Influence of gum chewing on postoperative bowel activity after complete staging surgery for gynecological malignancies: A randomized controlled trial

OBJECTIVE To investigate whether gum chewing affects the return of bowel function after complete staging surgery for gynecologic malignancies. METHODS A total of 149 patients undergoing abdominal complete surgical staging for various gynecological cancers were randomized into a gum-chewing group (n=74) or a control group (n=75). The patients chewed sugarless gum three times from the first postoperative morning until the first passage of flatus. Each chewing session lasted 30 min. Total abdominal hysterectomy with systematic pelvic and para-aortic lymphadenectomy was performed on all patients as part of complete staging surgery. Groups were compared in terms of time to first bowel movement time, first flatus and feces pass time, postoperative analgesic and antiemetic drug requirement, postoperative oral intake tolerance, mild ileus symptoms and hospital stay. RESULTS The mean time to flatus (34.0 ± 11.5 vs. 43.6 ± 14.0 h; p<0.001), mean time to defecation (49.6 ± 18.7 vs. 62.5 ± 21.5h; p<0.001), mean time to bowel movement (41.5 ± 15.7 vs. 50.1 ± 5.9h; p=0.001), mean time to tolerate diet (4.0 ± 0.8 vs. 5.0 ± 0.9 days; p<0.001), mean length of hospital stay (5.9 ± 1 vs. 7.0 ± 1.4 days; p<0.001) were significantly reduced in patients that chewed gum compared with controls. Mild ileus symptoms were observed in 27 (36%) patients in the control group compared to 11(14.9%) patients in the gum-chewing group [relative risk, 2.4; 95% confidence interval, 1.2-4.5; p=0.004]. Severe symptoms were observed in two patients (2.7%) in the control group. CONCLUSIONS Gum chewing early in the postoperative period following elective total abdominal hysterectomy and systematic retroperitoneal lymphadenectomy hastens time to bowel motility and ability to tolerate feedings. This inexpensive and well-tolerated treatment should be added as an adjunct in postoperative care of gynecologic oncology.

Use of additional oxytocin to reduce blood loss at elective caesarean section: A randomised control trial

Objective:  The purpose of this prospective, randomised, double‐blind, placebo‐controlled study was to assess the effects of a 5‐IU oxytocin bolus and placebo infusion versus a 5‐IU oxytocin bolus and 30 IU infusion on the control of blood loss at elective lower segment caesarean section (C/S).

Iatrogenic bladder injuries during caesarean delivery: A case control study

This study determined the rate, risk factors, management and outcome of bladder injury during caesarean section and suggests ways to improve the quality of care and reduce maternal morbidity and mortality. During the study period, there were 76 bladder injuries in 56,799 caesarean deliveries for an overall incidence of 0.13%. Women with a bladder injury were more likely to have had a prior caesarean delivery, as compared with the control group (72.4% vs 34.2%; p < 0.001). Cases were also more likely than controls to have had prior pelvic surgery. The presence of adhesions during the procedure was greater in the bladder injury group than the controls. In conclusion, our study suggests that a previous caesarean delivery is the most common risk factor for bladder injury during caesarean delivery. Moreover, the presence of labour, station of the presenting fetal part deeper than or equal to +1, and a large baby were independent risks for a bladder injury during caesarean delivery. Women requesting primary caesarean deliveries should be counselled about the potential for significant surgical complications in repeat caesarean deliveries when discussing the indications for a primary elective caesarean delivery.

Can preoperative neutrophil:lymphocyte and platelet:lymphocyte ratios be used as predictive markers for lymph node metastasis in squamous cell carcinoma of the vulva?

OBJECTIVE To determine whether the neutrophil:lymphocyte ratio (NLR) and platelet:lymphocyte ratio (PLR) before complete surgical staging provide information on lymph node metastasis in vulvar squamous cell carcinoma (SCC). STUDY DESIGN All patients with vulvar SCC who underwent complete surgical staging at two institutions between 1 January 2005 and 31 December 2011 were identified retrospectively from patient databases. Receiver operating characteristic (ROC) curve analysis was used to evaluate cut-off, sensitivity, and specificity values for preoperative NLR and PLR to predict lymph node metastasis. RESULTS Data from 64 women with adequate information were analyzed. Lymph node involvement was detected in 19 (29.7%) patients. NLR and PLR were higher in the lymph node--positive group than in the--negative group (p < 0.001). The best cut-off values for predicting lymph node metastasis were 2.81 for the NLR, with 84.5% sensitivity and 89.5% specificity, and 139.5 for the PLR, with 68.9% sensitivity and 89.5% specificity. Forty of the 64 (62.5%) patients had NLRs ≤ 2.81 and 24 (37.5%) had NLRs >2.81. Lymph node involvement was more common in the NLR >2.81 group [60.7% vs. 5.6%; relative risk RR = 10.9, 95% confidence interval CI = 2.7-43.4; p < 0.001]. Mean tumor sizes were 4.2 ± 2.3 cm in the NLR >2.81 group and 2.1 ± 1.2 cm in the NLR ≤ 2.81 group (p = 0.001). The rate of lymph node involvement was higher in the PLR >139.5 group than in the PLR ≤ 139.5 group (54.8% vs. 6.1%; RR = 9.0, 95% CI = 2.2-35.9; p<0.001). CONCLUSION Preoperative NLR and PLR are directly associated with nodal involvement status of vulvar SCC. These markers are simple, readily obtained and calculated, and easy to integrate into the surgical work-up of patients with vulvar SCC, at no extra cost.
