Vaccination in pregnancy.

The evidence indicates that pregnancy is associated with increased severity of some infectious diseases. Given the high maternal morbidity associated with influenza in pregnancy and the high neonatal morbidity and mortality associated with pertussis, the traditionally two recommended vaccines during pregnancy were those against influenza and Tdap (tetanus toxoid, reduced diphtheria toxoid and acellular pertussis) vaccines. The recent COVID-19 pandemic introduced a third vaccine that after much debate is now recommended for all pregnant women. Other vaccines can be offered based for high-risk pregnant women, and only when the benefits of receiving them outweigh the risks. The soon expected vaccines against group B streptococcus infection and respiratory syncytial virus infection will be a breakthrough in reducing perinatal mortality. In this paper, the recommendations for administration of each vaccine during pregnancy are discussed.

Effect of Sustained Uterine Compression versus Uterine Massage on Blood Loss after Vaginal Delivery: A Randomized Controlled Trial.

OBJECTIVE: This study aimed to compare the effectiveness of sustained uterine compression versus uterine massage in reducing blood loos after a vaginal delivery. STUDY DESIGN: This was a prospective randomized trial conducted at the American University of Beirut Medical Center (AUBMC) between October 2015 and October 2017. Inclusion criteria were women with a singleton pregnancy at ≥36 weeks of gestation, with less than three previous deliveries, who were candidates for vaginal delivery. Participants were randomized into two groups, a sustained uterine compression group (group 1) and a uterine massage group (group 2). Incidence of postpartum hemorrhage (blood loss of ≥500 mL) was the primary outcome. We assumed that the incidence of postpartum hemorrhage at our institution is similar to previously published studies. A total of 545 women were required in each arm to detect a reduction from 9.6 to 4.8% in the primary outcome (50% reduction) with a one-sided α of 0.05 and a power of 80%. Factoring in a 10% dropout rate. Secondary outcomes were admission to intensive care unit (ICU), postpartum complications, drop in hemoglobin, duration of hospital stay, maternal pain, use of uterotonics, or of surgical procedure for postpartum hemorrhage. RESULTS: A total of 550 pregnant women were recruited, 273 in group 1 and 277 in group 2. There was no statistically significant difference in baseline characteristics between the two groups. Type of anesthesia, rate of episiotomy, lacerations, and mean birth weight were also equal between the groups. Incidence of the primary outcome was not different between the two groups (group 1: 15.5%, group 2: 15.4%; p = 0.98). There was no statistically significant difference in any of the secondary outcomes between the two groups, including drop in hemoglobin (p = 0.79). CONCLUSION: There was no difference in blood loss between sustained uterine compression and uterine massage after vaginal delivery. KEY POINTS: · Transabdominal uterine compression and uterine massage are appropriate to prevent postpartum hemorrhage.. · No significant difference in blood loss or maternal discomfort observed between the two techniques.. · Both methods are equally effective and either one can be used based on provider preference..

Practice patterns of obstetric care in twin gestations: the value of MFM consultation.

OBJECTIVES: To evaluate the practice patterns among Lebanese obstetricians regarding obstetric care of twins and to compare selected practice patterns between general obstetricians and maternal fetal medicine physicians. METHODS: Questionnaires distributed during the annual meeting of the Lebanese Society of Obstetrics and Gynecology. RESULTS: Questionnaires were returned by 69.2% of the 296 physicians approached. Ten percent had fellowship training in Maternal Fetal Medicine (MFM). Thirty-nine percent perform cervical length measurement at 20-24 weeks of gestation and 34% recommend vaginal progesterone in case of a short cervix. When comparing selected practice patterns between MFM & general obstetricians, MFM specialists were less likely to perform cervical cerclage in the first trimester (5.9% versus 49%, p = .001), more likely to offer prenatal screening for aneuploidy (66.6% vs 46.4%, p = .03), less likely to use vaginal progesterone in the second trimester in the case of a short cervix (42.1% vs 61.8%, p = .04), less likely to perform serial ultrasound exam in the third trimester to assess fetal growth (50% vs 78%, p = .005) and more likely to deliver monoamniotic twins at 32-34 weeks of gestation (55% vs 37%, p = .05). CONCLUSION: Because of the different background of the Lebanese physicians, MFM specialists are more likely to follow obstetric care guidelines in twin gestation.

Practice and attitudes towards immunization among Lebanese obstetricians and gynecologists.

We designed our study to evaluate the knowledge and immunization practices among Lebanese obstetricians and gynecologists (OBGYN) for women of different age groups. Anonymous questionnaires were used to assess the knowledge and immunization practices among OBGYN. The survey was conducted at the annual meeting of the Lebanese Society of Obstetrics and Gynecology on November 13-15, 2014. Data collected included demographics, type of practice, academic background and familiarity with vaccine guidelines. Descriptive statistical methods were used to evaluate the responses. The response rate was 54.8% (114/208). Only 62.3% (71/114) recommend vaccination(s) to pregnant women with only 25.9% of those who recommend the Tdap vaccine for pregnant women giving it during the recommended third trimester. In addition, 52.6% are unaware of the CDC/ACIP immunization schedule for women in general. However, 83.0% (93/112) of respondents are willing to integrate vaccination in their practice. Our study highlights several gaps in the knowledge of Lebanese OBGYN regarding vaccination in addition to practices that are not in full accordance with common guidelines. Measures should be taken to spread proper awareness of the proper guidelines among Lebanese practitioners.

Intravenous Oxytocin Use to Decrease Blood Loss during Scheduled Cesarean Delivery: A Randomized Double-Blinded Controlled Trial (OXYTRIAL).

Objective The objective of this study was to determine the optimal dose of intravenous oxytocin administered during cesarean delivery (CD) to decrease the amount of blood loss. Methods Out of a total of 226 women presenting for CD, 189 patients were randomized into three groups by a computer-generated random number sequence table. Low-risk women with singleton term pregnancies undergoing scheduled CD were assigned to receive 20, 30, or 40 units (U) of oxytocin diluted in 500 mL of lactated Ringer solution intraoperatively. The primary outcome was the change in hemoglobin from pre-CD to post-CD. Results Overall, 63 women were assigned to each group. The primary outcome which was the drop in hemoglobin (1.4 ± 1.1 g/dL, 1.1 ± 0.8 g/dL, 1.0 ± 1.1 g/dL; p = 0.097) and the total calculated blood loss (798.6 ± 298.3 mL, 794.4 ± 313.5 mL, 820.2 ± 316.2 mL; p = 0.893) were not significantly different among the study groups. The incidence of intraoperative hypotension, postoperative systolic, and diastolic blood pressure changes was similar across the groups. Conclusion The amount of blood loss during CD was not significantly different among the three groups, thus the lowest dose of oxytocin infusion (20 U in 500 mL of lactated Ringer solution) seems to be an appropriate regimen.

Echogenic intracardiac focus on second trimester ultrasound: prevalence and significance in a Middle Eastern population.

OBJECTIVE: The association between echogenic intracardiac focus (EIF) and trisomy 21 is well established, with a recognized ethnic variation. Our study aimed to determine the prevalence of EIF in a Middle Eastern population and to examine its association with trisomy 21 and other adverse pregnancy outcomes. METHODS: Retrospective case-control study of second-trimester obstetric sonograms (16-28 weeks) performed at a tertiary care center over a 5-year period. Cases with EIF were retrieved, and a matched control group with no EIF was identified. The incidence of trisomy 21 and other adverse pregnancy outcomes was compared. RESULTS: A total of 9270 obstetric sonograms were examined, with an EIF prevalence of 2.5% (95% CI: 2.2-2.8%). Of patients with available outcome data, EIF was not associated with trisomy 21 (0/163 versus 1/163; p value = 1.00). Additionally, EIF was not associated with trisomy 18, trisomy 13, small for gestational age, preterm birth, fetal demise, cesarean delivery, operative vaginal delivery, or admission to the neonatal intensive care unit. CONCLUSION: In a contemporary Middle Eastern population, EIF is a rare occurrence. As an isolated finding, it is not associated with aneuploidy or other adverse pregnancy outcomes. EIF appears to be incidental with no impact on clinical practice.

Use of antenatal corticosteroids in the management of preterm delivery.

OBJECTIVE: This narrative review of the literature explores the current evidence and recommendations in favor of antenatal corticosteroids use during impending preterm deliveries as well as related issues and concerns. STUDY DESIGN: Synthesis of findings from published medical literature on antenatal corticosteroids and prematurity, retrieved from searches of computerized databases and authoritative texts. RESULTS: It is now recognized that an intramuscular course of betamethasone or dexamethasone given to a woman expected to deliver preterm not only accelerates pulmonary epithelial development but also matures other organ systems, significantly decreasing the chances of neonatal morbidities and increasing chances of survival. CONCLUSION: There remain uncertainties over the efficacy of the established protocol in populations such as the very early preterm, the late preterm, and multiple gestations. Alternative regimens remain controversial because of fear of adverse effects and doubts regarding whether benefits outweigh risks.

A clinical approach to intrahepatic cholestasis of pregnancy.

Intrahepatic cholestasis of pregnancy (ICP) has a varying prevalence worldwide. The etiology behind this disease remains not fully understood with multiple factors influencing its development including genetic variations, dietary factors, hormonal changes, and environmental influences. Presenting mainly during the third trimester with generalized itching and resolving spontaneously postpartum, this condition is still associated with fetal morbidity and mortality. The diagnosis is based on clinical presentation in association with biochemical abnormalities. Elevation in total bile acid levels is the most frequent laboratory abnormality and seems to be the most important for gauging further management of the disease. The most appropriate gestational age for the delivery of women with ICP is yet to be determined. In this review we discuss the epidemiology, clinical features, diagnosis, etiology, and management of ICP, trying to shed light on some controversial aspects of the disease.

Attitudes of Lebanese university students towards surgical hymen reconstruction.

Many cultural and religious beliefs place virginity at a high level of social significance, in that women who lose their virginity before marriage may face humiliation, ostracism, divorce, and extreme violence. This led to an increase in the demand for virginity restoration through surgical hymen reconstruction among these cultures. However, data regarding the acceptance of hymenoplasty in societies that consider sexuality a taboo are scarce. In this cross-sectional study, we investigated the effects of gender and religion on sexual attitudes towards hymenoplasty, premarital sex, and virginity in a sample of 600 Lebanese university students. Our findings showed that approval of hymenoplasty was low among participants regardless of gender (25.7 % men vs. 19.1 % women) and religious affiliations (22.5 % Muslims vs. 22.3 % Christians). Arguments for rejection were rooted in moral ethics and personal convictions: "form of deceiving and cheating" (80.7 %) and "betrayal of honesty in the relationship" (80.4 %). Reasons for acceptance included: personal belief in "women's rights, autonomy, and freedom" (72.2 %) and "physical harm and death" (63.5 %).Male participants were more likely to approve premarital coital sex than females (61.0 vs. 27.3 %). Muslims were also more likely to reject marrying a non-virgin than Christians (39.9 vs. 18.0 %). Female participants expressed more tolerance towards marrying a non-virgin male partner (78.3 vs. 57.3 %). Low acceptance of hymenoplasty among Lebanese university students was found to be related to moral ethics and personal convictions independently from gender and religious affiliation. Differences in sexual attitudes towards premarital coital sex and virginity, however, were more significantly influenced by culture and religion.

Effects of sildenafil in Nω-nitro-L-arginine methyl ester-induced intrauterine growth restriction in a rat model.

OBJECTIVE: To assess the effect of sildenafil citrate in a rat model of Nω-nitro-l-arginine methyl ester (L-NAME)-induced intrauterine growth restriction (IUGR). STUDY DESIGN: An in vivo experimental study was conducted where 40 pregnant Sprague-Dawley rats were randomly assigned to receive either: (1) control, (2) L-NAME 50 mg/kg/d by gavage (days 14 to 19), (3) L-NAME and sildenafil 15 mg/kg/d by gavage, or (4) sildenafil (days 14 to 21). On day 21, a hysterotomy was performed and all fetuses (live and dead) were counted, examined, and weighed. The primary outcome measure was the difference in pup birth weight. RESULTS: The median number of live pups per dam was 11.5 (range: 1 to 15), 13.5 (2 to 17), 13.5 (7 to 16), and 11.5 (4 to 17) in controls, L-NAME, sildenafil, and combined drug groups, respectively (p = 0.02). Rats treated with L-NAME had a significantly higher number of stillbirths compared with control (p = 0.013) and sildenafil (p = 0.008) groups. L-NAME reduced pup birth weight compared with controls (4.53 ± 1.49 versus 5.65 ± 1.63 g, p < 0.001); this effect was more pronounced in the L-NAME and sildenafil groups (3.37 ± 1.25 g, p < 0.001). CONCLUSION: Our data indicate that sildenafil citrate does not ameliorate L-NAME-induced IUGR, and in the doses utilized in this study might even have a synergistic negative effect on pup birth weight.

Effect of parity on maternal and neonatal outcomes in twin gestations.

OBJECTIVE: To compare maternal and neonatal outcomes of twin gestations in nulliparous and multiparous women. DESIGN: Retrospective analysis of maternal and neonatal records. SETTING: American University of Beirut Medical Center, a referral university-affiliated hospital. POPULATION: Pregnant women who delivered twin gestations beyond 24 weeks from 1990 to 2004. METHODS: The data collected were analyzed using Student's paired t-test or χ(2) test. Logistic regression analysis was used to study the effect of multiple variables on preterm delivery. MAIN OUTCOME MEASURE: Preterm birth rate. RESULTS: Nulliparas (n=333) were more likely to be younger (28.1±5.4 vs. 30.0±5.2 years; p<0.001) and the pregnancy a product of assisted reproductive technology (23.1 vs. 4.5%; p<0.001) compared with multiparas (n=508). They were at significantly increased risk of preterm delivery (54.4 vs. 45.1%; p=0.009) at lower gestational age (35.6±3.2 vs. 36.2±3.0 weeks; p=0.004). They had longer first and second stages of labor and a higher cesarean delivery rate (61.3 vs. 44.9%; p<0.001). Except for a higher intensive care nursery admission rate and longer nursery stay for twins of nulliparas, all neonatal morbidities were comparable. On multiple logistic regression analysis, multiparity (relative risk 0.70, 95% confidence interval 0.51-0.97) and growth restriction (relative risk 0.16, 95% confidence interval 0.12-0.22) were protective, while discordance (relative risk 2.24, 95% confidence interval 1.40-3.60) was a predictor of preterm delivery. CONCLUSIONS: Nulliparous women with twin gestations are at significantly higher risk for preterm delivery and cesarean delivery compared with multiparous women. Although this was not translated into higher perinatal mortality, these women should be monitored closely and counseled regarding these risks and their attendant morbidity.

Indomethacin in pregnancy: applications and safety.

Preterm labor (PTL) is a major cause of neonatal morbidity and mortality worldwide. Among the available tocolytics, indomethacin, a prostaglandin synthetase inhibitor, has been in use since the 1970s. Recent studies have suggested that prostaglandin synthetase inhibitors are superior to other tocolytics in delaying delivery for 48 hours and 7 days. However, increased neonatal complications including oligohydramnios, renal failure, necrotizing enterocolitis, intraventricular hemorrhage, and closure of the patent ductus arteriosus have been reported with the use of indomethacin. Indomethacin has been also used in women with short cervices as well as in those with idiopathic polyhydramnios. This article describes the mechanism of action of indomethacin and its clinical applications as a tocolytic agent in women with PTL and cerclage and its use in the context of polyhydramnios. The fetal and neonatal side effects of this drug are also summarized and guidelines for its use are proposed.

First trimester sonographic diagnosis of ectopia cordis: a case report and review of the literature.

A case of ectopia cordis (EC) with gastroschisis in a 27-year-old primigravida was diagnosed at 10(3/7) weeks of gestation. The pregnancy was terminated by suction dilatation and curettage. With the increasing use of first trimester ultrasonography, early detection of fetal abnormalities is becoming more frequent. We review other published cases of EC detected in the first trimester and discuss the possible advantages of early diagnosis including options of termination at earlier gestational ages which might decrease the physical and psychological trauma on some patients.

Oxytocin antagonists for the management of preterm birth: a review.

Preterm birth, the leading cause of neonatal morbidity and mortality, is estimated at incidence of 12.7% of all births, which has not decreased over the last four decades despite intensive antenatal care programs aimed at high-risk groups, the widespread use of tocolytics, and a series of other preventive and therapeutic interventions. Oxytocin antagonists, namely atosiban, represent an appealing choice that seems to be effective with apparently fewer side effects than the traditional tocolytics. This article reviews the available literature on the pharmacokinetics, mode of administration, and clinical utility of oxytocin antagonists for acute and maintenance tocolysis with special emphasis on its safety profile.

Calcium channel blockers for the management of preterm birth: a review.

Preterm birth continues to be the leading cause of perinatal morbidity and mortality. A wide range of tocolytics have been utilized for the management of preterm labor. Calcium channel blockers, namely nifedipine, gained popularity as tocolytics due to the oral route of administration, availability of immediate- and slow-release preparations, the low incidence of maternal adverse effects associated with their use, and the fact that they are inexpensive. This article reviews the available literature on the clinical utility of calcium channel blockers for acute and maintenance tocolysis with special emphasis on potential adverse effects, the most appropriate dose/regimen, and contemporary practice patterns among obstetricians. There are no randomized, placebo-controlled studies demonstrating the benefit of nifedipine in preterm labor. A suggested tocolytic protocol would be to start with the lowest dose of oral immediate-release nifedipine. For the first 48 hours thereafter, all attempts should be made not to exceed 60-mg daily doses.

Rheumatoid granuloma of the cervix and vagina: a challenging diagnosis and treatment.

BACKGROUND: Granulomas of the female genital tract are rare and usually occur after operative procedures. CASE: A patient with rheumatoid arthritis presented with vaginal discharge and bleeding with ulcerative, red, friable lesions of the cervix, which extended to the bladder floor and the right upper vaginal wall. Cervical biopsy was highly suggestive of rheumatoid nodules. This prompted revision of the diagnosis of tuberculosis, which was suspected several months earlier when pulmonary and renal lesions were noted. The cervico-vaginal lesions did not respond to local steroid treatment and improved when the systemic steroid dose was increased; however, they recurred on tapering the dose. CONCLUSION: Rheumatoid nodules can occur in the genital tract, which poses diagnostic and treatment challenges.

Effect of female nargile smoking on in vitro fertilization outcome.

OBJECTIVE: Smoking is a significant health hazard that has been associated with poor reproductive outcome and reduced fertility in reproductive age women. The aim of this study was to assess the effect of nargile smoking on intra-cytoplasmic sperm injection (ICSI) outcome. STUDY DESIGN: A prospective analysis of the outcomes of 297 women who underwent ICSI treatment at the ART Unit at the American University of Beirut Medical Center between January 1, and December 31, 2006 was done. The patients were divided into 3 groups based on their smoking status: cigarette smokers (n=42), nargile smokers (n=51) and non-smokers (n=204). RESULTS: The mean age of nargile smokers was significantly lower than the other groups; however, the 3 groups were similar with respect to the cause of infertility, total dose of follicular stimulating hormone (FSH), number of oocytes and embryos obtained, and number and quality of embryos transferred. There was no significant difference in the clinical pregnancy rate between nargile smokers and non-smokers (51.0% vs 43.6%). However, cigarette smokers had a significantly lower clinical pregnancy rate compared to non-smokers (23.8% vs 43.6%, p=0.0238). On multiple logistic regression analysis, factors that decreased the clinical pregnancy rates were cigarette smoking and maternal age. CONCLUSION: Although this study did not find a deleterious effect of nargile smoking on ICSI outcome, the results need to be confirmed in prospective studies that would include larger number of women with more objective measures of nargile smoke exposure.

Effect of religion on the attitude of primiparous women toward genetic testing.

BACKGROUND: Factors that influence a pregnant woman's decision to accept or decline genetic tests are largely undefined. The objective of this study was to determine the acceptance rate of prenatal diagnostic testing in Lebanon according to religion. METHODS: Prenatal charts were reviewed to obtain information about prenatal genetic testing. Women were divided according to their religion and were compared regarding the acceptance of triple screen test (TST) or amniocentesis (AMN) and reasons for declining such tests. Differences between groups were examined using the student's t-test, chi(2)-test and multivariate analysis (age >or= 35 years, religion, education and class). RESULTS: The religious distribution was 73.8% Moslems, 14.0% Christians and 11.2% Druze. Utilization of TST, AMN, and either (TST/AMN) was 61.2%, 7.6% and 67.0%, respectively. Uptake of TST/AMN was highest in Christians and lowest in Moslems and that of AMN higher in Christians >or= 35 years compared with Moslems. On multivariate analysis, none of the factors studied significantly affected the utilization of TST or TST/AMN except for age >or= 35 years which was associated with a borderline decrease in the utilization of TST Odds Ratio (OR) 0.485 (95% CI 0.21-1.12). The utilization of AMN significantly increased with age >or= 35 years OR 7.19 (95% CI 2.65-19.56) and lower education. CONCLUSION: Religion does not seem to affect utilization of prenatal diagnostic tests in Lebanon.

A short cervical length in pregnancy: management options.

Measuring cervical length using transvaginal ultrasonography is a useful tool to predict the risk of preterm birth in low- and high-risk pregnancies. Management of a short cervix poses a significant dilemma for clinicians. Different management plans have been proposed and studied, with mixed results in different clinical settings. This article reviews the various management options in the different patient subpopulations and proposes a scheme for management once a short cervix is identified.
