Transcatheter arterial chemoembolization versus systemic methotrexate for the management of cesarean scar pregnancy

Objective

To evaluate the effectiveness/safety of systemic methotrexate (MTX) treatment versus transcatheter arterial chemoembolization using different embolic agents for termination of cesarean scar pregnancy (CSP).

Methods

Women with CSP were randomized to receive intravenous infusion of MTX (group 1, n = 13), or chemoembolization with MTX and either gelatin sponge (GS; group 2, n = 15) or polyvinyl alcohol (PVA; group 3, n = 16) particles. Uterine suction curettage followed all procedures. Bleeding volume, time until resolution of serum β-hCG, and length of hospital stay were recorded as outcome endpoints.

Results

Bleeding volume was smaller in groups 2 (mean ± SD, 73 ± 20 mL) and 3 (63 ± 22 mL) than in group 1 (952 ± 471 mL) (P < 0.001). Time until resolution of β-hCG was shorter in groups 2 (29 ± 16 days) and 3 (30 ± 19 days) than in group 1 (57 ± 25 days) (P < 0.01). Length of hospital stay was shorter in groups 2 (13 ± 4 days) and 3 (12 ± 3 days) than in group 1 (36 ± 8 days) (P < 0.01).

Conclusion

Transcatheter arterial chemoembolization was more effective than systemic MTX treatment for termination of CSP. Large cohort studies are warranted to compare effectiveness between PVA and GS particles.     

Effect of isosorbide mononitrate for cervical ripening before surgical termination of pregnancy in the first trimester

Objective

To evaluate the efficacy of isosorbide mononitrate (IMN) for cervical ripening prior to first trimester surgical termination of pregnancy.

Methods

A prospective, double-blind, randomized, placebo-controlled trial. Women scheduled for surgical termination of a nonviable fetus before 12 weeks of gestation from October 2008 to June 2009 were enrolled and randomly assigned to receive either 20 mg vaginally of IMN (n = 24) or a placebo (n = 24) 4 hours before suction evacuation. Cervical dilation before evacuation was assessed with 10-mm Hegar dilators followed by smaller sizes that were measured until the instrument passed freely through the internal os. Cervical dilation, adverse effects, termination complications, and patient satisfaction were the main outcomes.

Results

Mean cervical dilation was not significantly different between the IMN and placebo groups (6.29 ± 0.99 mm vs 5.71 ± 1.04 mm; P = 0.05). Mean operative time did not differ between the groups (16 ± 0.07 min vs 18 ± 0.06 min; P = 0.55), nor did patient satisfaction measured by visual analogue scale (7.04 ± 1.68 vs 6.54 ± 1.22; P = 0.24).

Conclusion

IMN was comparable to placebo in terms of efficacy and patient satisfaction for cervical priming prior to first-trimester termination of pregnancy.     

Uterine artery embolization followed by dilation and curettage within 24 hours compared with systemic methotrexate for cesarean scar pregnancy

Objective

To assess the efficacy of uterine artery embolization (UAE) combined with dilation and curettage (D&C) within 24 hours for the treatment of a cesarean scar pregnancy (CSP), compared with methotrexate and D&C.

Methods

A retrospective cohort study of 119 women with CSP was conducted at two tertiary hospitals in Guangzhou and Shenzhen, China, during 2009–2012. Twenty-six women received systemic methotrexate followed by D&C, and 93 women were treated with UAE followed by D&C within 24 hours.

Results

Mean blood loss was 261.0 ± 357.4 mL in the methotrexate group versus 14.1 ± 40.6 mL in the UAE group (P < 0.001). The time to resolution of the level of β-human chorionic gonadotropin was 40.5 ± 17.2 days versus 15.4 ± 7.7 days (P < 0.001), respectively. The duration of hospitalization was 14.6 ± 9.2 days versus 6.2 ± 3.7 days (P < 0.001), respectively. An additional intervention was needed in 9 (35%) women in the methotrexate group and in 5 (5%) in the UAE group (P < 0.001).

Conclusion

UAE combined with D&C within 24 hours was an effective uterine preservation treatment for CSP, and was associated with less blood loss and a shorter hospital stay than administration of methotrexate followed by D&C.     

Urodynamic findings in women with pelvic organ prolapse and obstructive voiding symptoms

Objective

To determine whether obstructive voiding symptoms in women with advanced pelvic organ prolapse (POP) were associated with objective bladder outflow tract obstruction.

Methods

We reviewed preoperative data from patients with advanced POP who underwent surgical correction at the Department of Obstetrics and Gynecology, Carmel Medical Center, Haifa, Israel, between December 1, 2005, and November 30, 2007. Obstructive voiding symptoms were recorded from Pelvic Floor Distress Inventory-20 questionnaires.

Results

Of the 81 women aged 44-80 years who were included in the study, 40 (49.4%) reported incomplete bladder emptying preoperatively. There was no significant difference between these women and asymptomatic women in terms of demographic and clinical parameters such as age, parity, and stage of prolapse. Furthermore, there was no significant difference with regard to postvoid residual bladder volume (52.8 ± 65.8 vs 41.6 ± 41.2 mL), maximal (23.8 ± 11 vs 21.9 ± 9.6 mL/second) and average (10.3 ± 6.2 vs 9.3 ± 4 mL/second) urinary flow velocities, prevalence of increased postvoid residual volume (10.0% vs 4.8%), or obstructive urinary flow (17.5% vs 7.3%).

Conclusion

Almost half of all women with advanced POP experienced incomplete bladder emptying; however, this symptom did not correlate with objective urodynamic bladder outflow tract obstruction.     

Efficacy of transient abdominal ovariopexy in patients with severe endometriosis

Objective

To assess adhesion formation and fertility outcome after transient abdominal ovariopexy performed in patients with severe endometriosis.

Study design

Retrospective study including 218 patients who underwent surgery for severe endometriosis from 1997 to 2009. One hundred and thirty-nine (64%) patients were infertile. The initial ASRM stage was IV in 139 cases, III in 43 cases and II in 36 cases. Adnexal adhesions were scored by using the Operative Laparoscopy Study Group (OLSG) and modified AFS scoring systems. Unilateral or bilateral transient abdominal ovariopexy of 336 ovaries was performed to prevent adhesion formation or reformation for extensive surgery. In patients who underwent a second operation, adnexal adhesion scores were reported. Fertility outcome was evaluated by a questionnaire.

Results

Second-look surgery was performed after 11.7 ± 2.4 months in 24 patients (11%) who had undergone 38 ovariopexies. Transient abdominal ovariopexy significantly decreased adnexal adhesion scores (p < 0.05). Regarding fertility outcome, the median follow up was 19.6 ± 1.5 months. Fifty-eight patients, out of 105 infertile women who actively tried to conceive after surgery, conceived, 21 (36%) spontaneously and 37 (64%) after ART. The median time interval for conception was 8.6 ± 1 months.

Conclusion

In patients with severe endometriosis, transient abdominal ovariopexy is an effective technique in preventing postoperative adhesion formation and in improving fertility outcome.

Condensation

In 218 patients with severe endometriosis, transient abdominal ovariopexy was an effective technique in preventing adhesion formation and improving fertility outcome.     

Cost-effectiveness of misoprostol and prenatal iron supplementation as maternal mortality interventions in home births in rural India

Objective

To determine the cost-effectiveness of prenatal iron supplementation and misoprostol use as interventions to prevent maternal mortality in home births in rural India.

Methods

A cost-effectiveness analysis depicted three hypothetical cohorts of 10 000 pregnant women delivering at home in rural India: one with no intervention, one receiving standard prenatal iron supplements, and 1 receiving 600 µg of misoprostol in the third stage of labor.

Results

Misoprostol used to prevent postpartum hemorrhage resulted in a 38% (95% CI, 5%-73%) decrease in maternal deaths, while prenatal iron supplementation resulted in a 5% (95% CI, 0%-47%) decrease. Misoprostol cost a median US $1401 (IQR US $1008-$1848) prenatal iron supplementation cost a median US $2241 (IQR No Lives Saved-$3882) per life saved compared with the standard care outcome.

Conclusion

Misoprostol is a cost-effective maternal mortality intervention for home births. Iron supplementation may be worthwhile to improve women's health, but it is uncertain whether it can prevent mortality after hemorrhage.     

Peripartum cardiomyopathy

Objective

To determine the clinical and echocardiographic profiles of women with peripartum cardiomyopathy and ascertain the natural course of the disease.

Methods

Fifty-six women with peripartum cardiomyopathy were followed up for a mean period of 6.1 years and their clinical and echocardiographic profiles were studied as well as their outcomes.

Results

The mean ± SD age at presentation was 31 ± 5 years and mean parity was 2.6 ± 1. Of the 56 patients, 18 (32.1%) had NYHA Class II, 24 (42.9%) had NYHA Class III, and 14 (25%) had NYHA Class IV symptoms, and 21 (37.5%) and 35 (62.5%), respectively, presented with features of heart failure during pregnancy and the postpartum. During follow-up, the left ventricular ejection fraction improved from 31% ± 7.2% to 43% ± 8% (P ≤ 0.05). Nine patients (16.1%) became pregnant, with a mortality of 55.5% during pregnancy and 23.2% during follow-up.

Conclusion

Women with peripartum cardiomyopathy present with severe left ventricular dysfunction late in the pregnancy or early in the puerperium. A considerable number of women still die from this condition despite the use of angiotensin-converting enzyme inhibitors and β-blockers. A subsequent pregnancy carries a very high risk of mortality.     

Bilateral uterine artery ligation plus B-Lynch procedure for atonic postpartum hemorrhage with placenta accreta

Objective

To assess the effectiveness of bilateral uterine artery ligation followed by B-Lynch compression suturing in women with atonic postpartum hemorrhage and placental site bleeding due to adherent placenta accreta.

Method

This protocol was followed in 26 women undergoing cesarean delivery for placenta accreta.

Results

Two women died from disseminated intravascular coagulopathy. In the remaining 24 women, placental remnants completely disappeared within 8 months and ovulation resumed after a mean ± SD of 51.6 ± 3.2 days. Moreover, 18 women (75%) became pregnant within 12 months.

Conclusion

Atonic postpartum hemorrhage and placental site bleeding due to adherent placenta accreta can be safely controlled by bilateral uterine artery ligation followed by B-Lynch compression suturing in women who desire to remain fertile.     

Phase II trial of adjuvant pelvic radiation "sandwiched" between combination paclitaxel and carboplatin in women with uterine papillary serous carcinoma

Objective

To evaluate the safety and survival in women treated with adjuvant pelvic radiation “sandwiched” between six cycles of paclitaxel and carboplatin chemotherapy with completely resected UPSC.

Methods

Surgically staged women with UPSC (FIGO stage 1-4) and no visible residual disease were enrolled. Treatment involved paclitaxel (175 mg/m²) and carboplatin (AUC = 6.0-7.5) every 21 days for 3 doses, followed by radiation therapy (RT), followed by an additional 3 cycles of paclitaxel and carboplatin (AUC = 5-6). Survival analysis, using Kaplan-Meier methods, was performed on patients who completed at least 3 cycles of chemotherapy and RT.

Results

A total of 81 patients were enrolled, of which 72 patients completed the first 3 cycles of chemotherapy followed by prescribed RT. Median age was 67 years (range: 43-82 years). 59/72 (82%) had disease confined to the uterus and 13/72 (18%) had completely resected extra-uterine disease (stage 3 and 4). 65 (83%) completed the protocol. Overall PFS and OS for combined stage 1 and 2 patients was 65.5 ± 3.6 months and 76.5 ± 4.3 months, respectively. PFS and OS for combined stage 3 and 4 patients was 25.8 ± 3.0 and 35.9 ± 5.3 months, respectively. Three-year % survival probability for stage 1 and 2 patients was 84% and for stage 3 and 4 patients was 50%. Of the 435 chemotherapy cycles administered, there were 11(2.5%) G3/G4 non-hematologic toxicities. 26(6.0%) cycles had dose reductions and 37(8.5%) had dose delays.

Conclusions

Compared to prior studies of single modality adjuvant therapy, RT “sandwiched” between paclitaxel and carboplatin chemotherapy is well-tolerated and highly efficacious in women with completely resected UPSC.     

A phase II evaluation of docetaxel and carboplatin followed by tumor volume directed pelvic plus or minus paraaortic irradiation for stage III endometrial cancer

Objective

To determine the feasibility and efficacy of administering docetaxel and carboplatin chemotherapy followed by tumor directed radiation in patients with advance stage endometrial cancer.

Methods

Patients with surgical stage III or IV (confined to the pelvis) endometrial cancer were eligible. Treatment consisted of six cycles of docetaxel (75 mg/m²) and carboplatin (AUC 6) followed by irradiation to the involved field (50.4 Gy pelvis ± 43.5 Gy paraaortic) ± brachytherapy. Kaplan-Meier (KM) methods estimated overall survival (OS) and progression free survival (PFS).

Results

Forty-five patients were enrolled, 34 (76.0%) completed the prescribed therapy. Median age 63.5 (35-85 years). Stage IIIA 8 (17.8%), IIIB 1 (2.2%) and IIIC 36 (80.0%). 39/45 (86.7%) had endometroid histology. Serious grade 4 toxicities included 14 non-hematologic and 2 hematologic. Sixteen patients died following treatment, 6 from recurrent progressive cancer, with a median follow-up of 35.6 months (0.4-74.8). KM estimates and standard error (SE) for OS at 1 year were 84.5%, (5.4%), at 3 years, 65.8%, (7.2%) and at 5 years, 56.7%, (7.9%). Median overall survival was 74.5 months. Fourteen patients recurred with KM estimates and standard error (SE) for PFS at 1 year 77.8%, (6.2%) and 3 year 54.4%, (6.7%). Median progression free survival was 36.9 months.

Conclusions

Docetaxel and carboplatin followed by tumor directed irradiation for advanced stage endometrial cancer has acceptable toxicity and efficacy that allows for this regimen to be considered a viable treatment option for these patients.     

Maternal serum protein S forms in pregnancies complicated by intrauterine growth restriction

Objectives

The clinical relevance of protein S deficiency in pregnant women remains controversial. Major debate exists regarding which parameter (total protein S antigen, free protein S antigen or functional protein S) should be evaluated in order to define protein S deficiency. The present study aimed to identify which of these parameters correlate with intrauterine growth restriction (IUGR).

Study design

A retrospective case-control study of women with IUGR (n = 27) and healthy controls (n = 123) in the third trimester of pregnancy.

Results

The maternal serum of women in the IUGR group had significantly lower levels of functional and free protein S compared with the control group: 54.07 ± 24.72% vs 65.20 ± 17.95% (p < 0.005) and 42.88 ± 11.01% vs 56.64 ± 13.30% (p < 0.0001), respectively. No significant correlation was found between total protein S and IUGR.

Conclusions

Levels of functional and free protein S are correlated with IUGR.     

Laparoscopic ovarian cystectomy of endometriomas: surgeons' experience may affect ovarian reserve and live-born rate in infertile patients with in vitro fertilization-intracytoplasmic sperm injection

Objective

To assess whether the laparoscopist's experience can affect ovarian reserve and pregnancy outcome in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) patients who previously underwent laparoscopic conservative treatment for ovarian endometriomas.

Study design

One hundred and forty-nine IVF-ICSI cycles with infertile patients who previously underwent laparoscopic conservative treatment for ovarian endometriomas were enrolled. There were 76 cycles with an inexperienced surgeon and 73 cycles with an experienced surgeon.

Results

The number of antral follicle count (7.5 ± 3.8 vs. 9.6 ± 6.6; p = 0.011), and live-born rate per cycle (9.3% vs. 32.9%; p < 0.001) were significantly lower in the inexperienced group comparing with the experienced group. However, the mean number of oocytes, fertilization rate, mean number of embryos transferred, rate of good-quality embryos transferred, implantation rate and clinical pregnancy were similar between both groups.

Conclusions

The experience of the laparoscopist may affect ovarian reserve and live-born rate after treating ovarian endometrioma in infertile women with IVF-ICSI.     

Oral misoprostol reduces vaginal bleeding following surgical evacuation for first trimester spontaneous abortion

Objective

To assess the effectiveness and tolerability of misoprostol to reduce the amount and duration of vaginal bleeding following surgical evacuation for first trimester spontaneous abortion.

Methods

A total of 160 patients who underwent surgical evacuation for first trimester spontaneous abortion between 8 and 12 weeks of pregnancy were randomized into 2 groups to receive either 200 µg of oral misoprostol immediately after evacuation followed every 6 hours for 48 hours or no misoprostol. Pain scores, duration and amount of bleeding, and endometrial thickness were assessed over 10 days.

Results

Women who received misoprostol had significantly fewer bleeding days after evacuation (4.11 ± 2.69 vs 5.89 ± 3.06; P < 0.001), fewer patients reported vaginal bleeding lasting 10 days or more (3.8% vs 15.0%; P = 0.014), and endometrial thickness 10 days after evacuation was less (6.25 ± 2.38 vs 7.23 ± 1.94; P = 0.05). Pain scores were comparable in both groups (1.54 ± 0.65 vs 1.63 ± 0.83; P = 0.40) after 10 days.

Conclusion

Oral misoprostol is effective in reducing the prevalence and amount of vaginal bleeding after surgical evacuation for first trimester spontaneous abortion.     

Maternal and perinatal outcomes of visceral leishmaniasis (kala-azar) treated with sodium stibogluconate in eastern Sudan

Objective

To investigate maternal and perinatal outcomes when pregnant women with visceral leishmaniasis (VL, also known as kala-azar) are treated with the antimonial sodium stibogluconate.

Method

Forty-two pregnant women with VL were treated with sodium stibogluconate at Gadarif Hospital, Gadarif, Sudan, and mother and child were followed up for 1 year.

Results

The treatment began at a mean ± SD of 24.4 ± 9.2 weeks of pregnancy. None of the patients had malaria or HIV. Two (4.7%) who received the treatment in the first trimester had miscarriages; 4 (4.9%) died from hepatic encephalopathy during the second week of treatment; and 2 (4.7%) had preterm deliveries. One of the newborns had a myelomeningocele and died at 2 hours, and the other died from VL at 2 months.

Conclusion

Preventive measures against VL should be employed in the region, and more research on VL and its treatment during pregnancy is needed.     

Induction of labor with vaginal misoprostol plus oxytocin versus oxytocin alone

Objective

To compare the effect of an oxytocin infusion alone or preceded by an intravaginal application of misoprostol for labor induction in women with term pregnancies and a low Bishop score.

Methods

This study randomized 100 multiparous women with singleton pregnancies over 38 weeks and a Bishop score less than 6 to receive either a single 50-µg dose of misoprostol intravaginally 3 hours before initiation of the oxytocin infusion or only an oxytocin infusion. The time from induction to delivery, the route of delivery, and maternal and fetal outcomes were analyzed.

Results

The mean time from induction to delivery was 9.36 ± 1.97 hours in the misoprostol plus oxytocin group and 11.08 ± 3.23 in the oxytocin alone group (P = 0.002). The rates of vaginal delivery, 1- and 5-minute Agpar scores, placental abruption, and postpartum hemorrhage were similar between the 2 groups, as were the rates of admission to the neonatal intensive care unit. There were no cases of perinatal asphyxia.

Conclusion

A 50-µg intravaginal application of misoprostol before starting the oxytocin infusion is a more effective method of labor induction than an oxytocin infusion alone for our study population.     

Single-port laparoscopic myomectomy using transumbilical GelPort access

Objective

To describe our initial experience with single-port laparoscopic myomectomy (SP-LM) using transumbilical GelPort access and the surgical technique used, and to evaluate the safety and feasibility of this procedure.

Study design

A prospective observational study was performed at a university teaching hospital from January 2009 to December 2009. Fifteen patients with symptomatic subserosal or superficial intramural myomas (≤8 cm) underwent SP-LM.

Results

The mean age and body mass index were 35.0 ± 8.6 years and 22.6 ± 2.6 kg/m². Two patients had a history of previous abdominal surgery, consisting of one and two cesarean deliveries. The mean operating time, hemoglobin change, return of bowel activity, and length of hospital stay were 81 ± 21.5 min, 1.1 ± 0.5 g/dL, 34.3 ± 5.9 h, and 3.1 ± 0.5 days, respectively. In one patient (6.7%), SP-LM was converted to two-port LM. There were no surgical or wound complications in any patient, and the histopathological result was leiomyoma in all the cases.

Conclusion

SP-LM is feasible in selected patients with symptomatic myoma.     

Abdominal electromyography may predict the response to tocolysis in preterm labor

Objective

To determine whether abdominal electromyography can predict the response to tocolysis in pregnant women in preterm labor.

Study design

This study was carried out at the Department of Obstetrics and Gynecology, Menofyia University Hospital in Egypt. Fifty pregnant women in preterm labor who fulfilled the inclusion criteria were enrolled. Baseline abdominal electromyography was performed. Tocolysis in the form of hexoprenaline sulphate infusion was started for all women and electromyography was repeated after 24 h in responders but only after 6 h in non responders. The receiver operating characteristics curve was drawn to calculate specificity of the electromyography at 100% sensitivity. Results were tabulated and statistically analyzed.

Results

Forty women responded to tocolysis by delaying delivery for more than 48 h. There was a significant reduction in the frequency of uterine contractions after tocolysis (3.76 ± 0.92 versus 2.32 ± 2.05 contractions per 10 min; P < 0.001). Similar significant reductions affected the duration and amplitude of uterine action potentials (25.08 ± 9.74 versus 14.4 ± 17.16 s; P < 0.001, 40.8 ±  25.89 versus 28.32 ± 29.38 mV; P < 0.001). At a sensitivity of 100% and using ROC curve, abdominal electromyography of amplitude of 82 mV lasting for 30 s or more had a specificity of 90%, positive and negative predictive values of 67% and 95%, and a diagnostic accuracy of 88% in predicting preterm labor.

Conclusion

Abdominal electromyography may predict the response to tocolysis in preterm labor.     

Meperidine versus valethamate bromide in shortening the duration of active labor

Objective

To compare the efficacy and safety of meperidine hydrochloride and valethamate bromide against placebo in shortening the duration of active labor.

Method

We randomly assigned 160 nulliparous women with a singleton pregnancy at term who needed induction of labor to one of 3 treatments: 50 mg of meperidine (n = 53), 16 mg of valethamate bromide (n = 53), or a normal saline solution as placebo (n = 54). All medications were given by slow intravenous infusion. Labor duration was the main outcome measure.

Results

The intervals between infusion and complete cervical dilation and between infusion and delivery were significantly reduced (P < 0.001 and P < 0.01) in the meperidine group (103.0 ± 64.5 minutes and 119.8 ± 70.2 minutes), in contrast to the placebo group (173.9 ± 74.8 minutes and 192.2 ± 82.8 minutes). However, differences were not significant between the 2 treatment groups (139.6 ± 63.1 minutes and 160.6 ± 71.9 minutes), or between the valethamate bromide and the placebo group.

Conclusion

Meperidine, but not valethamate bromide, significantly shortened the duration of active labor in nulliparous women with a singleton pregnancy at term.     

Determinants of fertility and reproductive success after hysteroscopic septoplasty for women with unexplained primary infertility: a prospective analysis of 88 cases

Objective

To evaluate prospectively the effect of hysteroscopic septoplasty as therapy for unexplained primary infertility in women with uterine septum as a sole cause for reproductive failure and to define the factors influencing reproductive success.

Study design

In a prospective comparative study, we enrolled 103 infertile women with uterine septum as a sole cause for reproductive failure. They had had unexplained primary infertility >2 years and a follow-up >12 months. Uterine anomalies were diagnosed by means of hysterosalpingography (HSG) and 2D-transvaginal sonography (TVS) with intrauterine saline infusion. Hysteroscopic septoplasty was performed in the early follicular phase. Pregnancy rates (PR) according to patient and septum characteristics (septum size) were the main outcome measures.

Results

Follow-up was complete for 88 patients. The mean (±SD) age of the patients was 36.1 ± 2.1 years. Forty-two patients became pregnant (40.7%). The mean (±SD) delay in conception was 7.5 ± 2.6 months. Nearly 80% of the pregnant women conceived spontaneously. Of 44 pregnancies in 42 women, 36 live newborns were delivered. The PR was significantly higher in women <35 years of age or with <3 years of unexplained primary infertility. Moreover, in women with a septum size larger than one-half of their uterine length the PR was significantly higher than those with septum size <1/2 of their uterus (P = .12).

Conclusion

Fertility and pregnancy after hysteroscopic septoplasty in women with unexplained primary infertility and uterine septum as a sole cause for reproductive failure seems to depend on patient age, duration of infertility before septoplasty, and septum size. Women with a septum size larger than one-half of their uterine length have a higher chance of successful pregnancy after hysteroscopic septoplasty.
