Spinal versus general anesthesia in cesarean sections: the effects on postoperative pain perception.

OBJECTIVE: To compare postoperative pain perception and analgesia requirements in patients undergoing cesarean section (CS) using general versus spinal anesthesia. STUDY DESIGN: A prospective, observational study of patients undergoing elective CS during 2009 under either general or spinal anesthesia. Postoperative pain intensity and analgesia requirements were evaluated for up to 48 h after surgery. RESULTS: A total of 153 women were enrolled; 77 received general and 76 received regional anesthesia. Postoperative meperidine requirements in the first 24 h were significantly higher in the general anesthesia group. Pain scores were mostly comparable between the groups. Nevertheless, lower pain scores were graded after 8 h in the general versus the spinal anesthesia and this reversed at 48 h. CONCLUSION: Spinal anesthesia is comparable to general anesthesia in terms of post-operative pain control. In choosing the type of anesthesia in CS, other factors such as the urgency and potential maternal and fetal hazards should be taken into account.

Is colonization with GBS in a previous pregnancy associated with adverse perinatal outcomes?

OBJECTIVE: To investigate whether colonization with GBS in a previous pregnancy is associated subsequently with adverse obstetric and perinatal outcomes. METHODS: A retrospective study was undertaken comparing pregnancy complications of patients with and without colonization with GBS in a previous pregnancy from 1988 to 2006. Women with a positive GBS culture in the current pregnancy, women lacking prenatal care and multiple gestations were excluded from the analysis. MAIN OUTCOME MEASURES: Adverse obstetric and perinatal outcomes including premature rupture of membranes, intrapartum fever, chorioamnionitis and perinatal mortality. RESULTS: Out of 184,266 singleton deliveries, 230 (0.12%) were of patients with a positive GBS culture in their previous pregnancy. Previous GBS colonization was not found to be associated with adverse pregnancy outcomes such as PROM (9.1 vs. 6.8%; P = 0.16), intrapartum fever (1.3 vs. 2.2%; P = 0.72) and chorioamnionitis (1.3 vs. 0.8%; P = 0.29). CONCLUSIONS: GBS colonization in a previous pregnancy is not associated with adverse pregnancy outcomes in the current pregnancy.

Third stage of labor placental complications and placenta-associated syndromes.

OBJECTIVE: To evaluate the association between third stage placental complications and placental insufficiency associated disorders, also known as, placenta associated syndromes. STUDY DESIGN: A population-based retrospective cohort study comparing placental-related perinatal outcomes of parturient with (study group) and without third stage placental complications, defined as a composite of retained placenta, adherent placenta, placenta accrete, need for manual removal of the placenta, postpartum curettage and revision of the uterine cavity. A univariate analysis was followed by a multivariable logistic regression model. RESULTS: During the study period, 263,023 deliveries met inclusion criteria, of which, 10,281 (3.9%) experienced placental complications during the third stage of labor. Parturient in the study group had significantly higher rates of placental insufficiency associated disorders which included among others: hypertensive disorders of pregnancy (6.5 versus 5.6%, p < .001), stillbirth (1.9 versus 0.7%, p < .001) and preterm delivery (9.9 versus 7.7%, p < .001). Using a multivariable regression model, while controlling for confounders such as maternal age and induction of labor, third stage placental complications were independently associated with placental insufficiency associated disorders. CONCLUSION: Our findings suggest that placental associated adverse pregnancy outcomes and third stage placental complications may represent different manifestations of a common pathological or inadequate placentation process.

Risk factors for obstetric anal sphincter injuries (OASIS) during vacuum extraction delivery in a university affiliated maternity hospital.

Introduction: Instrumental delivery is a well-known risk factor for obstetric anal sphincter injuries (OASIS). The specific characteristics among patient undergoing vacuum extraction delivery (VE) are less studied. Therefore, we aimed to evaluate risk factors for OASIS among parturient that underwent a VE delivery in a large university affiliated maternity hospital.Material and methods: The study population contained 9116 women who delivered by VE in tertiary medical center from 1988 to 2015. Inclusion criteria included deliveries beyond 24-week gestation. Multiple gestations and pregnancies complicated with stillbirth were excluded from the analysis. Maternal obstetric variables were compared between parturient with and without OASIS. Independent risk factors for OASIS were assessed by multivariable logistic regression modeling.Results: OASIS was diagnosed in 94 women (1.03%) following vacuum extraction. Among patients who underwent a VE delivery, gravidity and parity were found to be significantly lower in patients with OASIS. A multivariable logistic regression model with OASIS as the outcome variable revealed that among women who underwent VE, while episiotomy and delivery of a macrosomic neonate were not independently associated with OASIS, a strong association between nulliparity and OASIS was found (OR 3.34; 95% CI 1.93-5.78; p < .001).Conclusions: OASIS is uncommon in our population. Vacuum extraction in nulliparous parturient is a significant risk factor for OASIS. Our results should be taken into account when managing nulliparous deliveries.

Neonatal outcome in preterm deliveries between 23 and 27 weeks' gestation with and without preterm premature rupture of membranes.

OBJECTIVES: To characterize neonatal morbidity and mortality rates in extreme preterm deliveries (between 23 and 27 weeks' gestation) with and without PPROM, and to evaluate the association between PPROM and chorioamnionitis. METHODS: A retrospective population-based study was conducted on preterm singleton pregnancies delivered between 23 and 27 weeks' gestation from 1988 to 2007. Immediate neonatal morbidity and mortality rates in pregnancies complicated by PPROM were compared to pregnancies with intact membranes. A multivariate analysis was conducted in order to determine the independent association between PPROM and chorioamnionitis. RESULTS: Out of 1,437 preterm deliveries, 236 (16.4%) were complicated with PPROM. There were more neonates with low 1 min (61.0 vs. 42.5%; P = 0.001) and low 5 min (30.1 vs. 23.8%; P = 0.042) Apgar scores (of less than 7) in pregnancies complicated by PPROM than in the comparison group. There were more cases of chorioamnionitis in the PPROM group born at 23-24 weeks' gestation (33.8 vs. 17.0%; P < 0.001), and in the PPROM group born at 25-27 weeks (42.0 vs. 15.5%; P < 0.001). In the group born at 23-24 weeks' gestation, there were more postpartum deaths (PPD) in the PPROM group (70.0 vs. 54.8%; P = 0.013); however, there was no significant difference in PPD in the groups born at 25-27 weeks. In the group born at 23-24 weeks, as well as at 25-27 weeks, there were fewer antepartum deaths (APD) in the PPROM group as compared to the control group (16.3 vs. 32.6%; P = 0.002, and 5.3 vs. 36.3%; P < 0.001; respectively). After adjusting for gestational age and gender, using a multivariate analysis, the association between PPROM and chorioamnionitis remained significant (OR = 3.32; 95% CI 2.43-4.51, P < 0.001). CONCLUSIONS: PPROM is associated with adverse perinatal outcome in deliveries between 23 and 27 weeks' gestation. Moreover, PPROM is an independent risk factor for chorioamnionitis.

Perinatal mortality: a sporadic event or a recurrent catastrophe?

OBJECTIVE: The purpose of this study was to determine whether women who experienced perinatal mortality in their first delivery had, in their subsequent birth, a higher risk for adverse perinatal outcome. METHODS: A population-based study was undertaken to compare all second deliveries of women with previous perinatal mortality in their first delivery to those with no such history. Deliveries occurred from 1988 to 2004 in a tertiary medical center. Patients lacking prenatal care, multiple gestations, and congenital malformations were excluded from the analysis. A multivariable logistic regression model and the Mantel-Haenszel procedure were carried out to control for confounders. RESULTS: During the study period, out of 25,876 singleton second deliveries, 230 (0.9%) cases were of patients with previous perinatal mortality. Multivariable analysis with backward elimination showed a significant association between previous perinatal mortality and the following conditions: hypertensive disorders (OR=2.6, 95% CI 1.7-3.9, P<0.001), diabetes mellitus (OR=2.4, 95% CI 1.5-3.7, P<0.001), fertility treatment (OR=2.7, 95% CI 1.6-4.7, P=0.001), and younger maternal age (OR=0.9, 95% CI 0.92-0.98, P<0.001). Controlling for preterm delivery, using the Mantel-Haenszel procedure, the association between previous and subsequent perinatal mortality remained significant (weighted OR=2.2, 95% CI 1.2-3.9, P=0.010). CONCLUSION: Previous perinatal loss poses an independent risk for subsequent perinatal mortality. Prospective studies are warranted in order to establish the appropriate means of surveillance and/or interventions needed to decrease future adverse perinatal outcomes.

Chorioamnionitis caused by Serratia marcescens in a healthy pregnant woman with preterm premature rupture of membranes: A rare case report and review of the literature.

The incidence of chorioamnionitis varies widely. The highest incidence is reported in preterm deliveries. Among preterm deliveries, chorioamnionitis usually occurs after preterm premature rupture of membranes (PPROM). To date, only five cases of chorioamnionitis due to Serratia marcescens were reported. Here we present a case of a pregnant woman with chorioamnionitis due to Serratia marcescens who delivered a premature neonate at 28 weeks and four days of gestation. We also conducted a review of the literature in order to identify and characterize the clinical presentation and outcomes of this rare infection. A 36 year old female (gravida 9, para 6) was admitted with cervical effacement of 16mm and intact membranes at gestational age of 25 weeks and five days. One week following her admission PPROM was noticed. Treatment with the standard antibiotic regimen for PPROM was initiated. Thirteen days after the diagnosis of PPROM (28 weeks and four days) she developed chills, abdominal pain, sub febrile fever, tachycardia, leukocytosis and fetal tachycardia, and a clinical diagnosis of chorioamnionitis was made. An urgent CS was performed. In the first post-operative day the patient developed surgical sight infection. Cultures obtained from the purulent discharge of the wound, as well as cultures from the placenta and uterine cavity that were obtained during surgery grew Serratia marcescens. The patient was treated with Meropenem for six days, with a good clinical response. We present a rare case of nosocomialy acquired Serratia marcescens chorioamnionitis in a patient with PPROM. This case emphasizes the need for good infection control measures. Our favorable outcome together with the scares reports in the literature, add insight into this type of rare infection.

Dilated cardiomyopathy in a pregnant woman after doxorubicin and radiotherapy for Hodgkin's disease: a case report.

BACKGROUND: Hodgkin's disease occurs frequently in women of reproductive age. Anthracyclines in general and doxorubicin in particular are integral parts of therapy. CASE: A 24-year-old primigravida had dilated cardiomyopathy diagnosed at 34 weeks'gestation. Three years earlier she had been treated with chest radiation and combination chemotherapy, including doxorubicin, for Hodgkin's disease. CONCLUSION: The clinician should be aware of this manifestation. Multidisciplinary supervision throughout pregnancy as well as planned timing and mode of delivery are mandatory.

Macrophage infiltration and stress-signaling in omental and subcutaneous adipose tissue in diabetic pregnancies.

OBJECTIVE: To examine if, as in obesity, pregnancies complicated by gestational diabetes mellitus (GDM) exhibit increased macrophage infiltration and activated MAP-kinases in omental adipose tissue. METHODS: Paired omental (OM) and abdominal subcutaneous (SC) fat samples were collected from 11 GDM and 20 normal pregnancies during cesarean delivery. Tissues were stained to detect macrophages, and analyzed to assess MAP-kinases. RESULTS: OM had higher macrophage counts than SC in GDM (6.10 ± 2.20 versus 2.53 ± 1.45, p = 0.04), but not in normal pregnancies (p = 0.346). GDM pregnancies had more macrophages than normal pregnancies in OM (6.10 ± 2.20 versus 1.29 ± 0.55, p = 0.01), while only a trend was observed in SC fat (p = 0.08). Significant correlation (R = 0.619, p = 0.005) was observed between OM-macrophage infiltration and insulin resistance. Using multivariate analysis, only obesity independently associated with GDM. Expression of total p38MAP-kinase was higher in OM versus SC in both normal and GDM pregnancies, without significant differences between these groups. However, expression of activated p-p38MAP-kinase, and its upstream kinase MKK4, was comparable between fat depots. CONCLUSION: GDM pregnancies demonstrate increased macrophage infiltration to OM fat, correlating with higher insulin resistance. As in non-pregnant-patients obesity and OM macrophage infiltration may be on the same causal pathway, leading to GDM. Yet, this occurs without activation of p38MAP-kinase signaling.

DIC score in pregnant women--a population based modification of the International Society on Thrombosis and Hemostasis score.

OBJECTIVES: The objectives of this study were: 1) To determine the component needed to generate a validated DIC score during pregnancy. 2) To validate such scoring system in the identification of patients with clinical diagnosis of DIC. MATERIAL AND METHODS: This is a population based retrospective study, including all women who gave birth at the 'Soroka University Medical Center' during the study period, and have had blood coagulation tests including complete blood cell count, prothrombin time (PT)(seconds), partial thromboplastin time (aPTT), fibrinogen, and D-dimers. Nomograms for pregnancy were established, and DIC score was constructed based on ROC curve analyses. RESULTS: 1) maternal plasma fibrinogen concentrations increased during pregnancy; 2) maternal platelet count decreased gradually during gestation; 3) the PT and PTT values did not change with advancing gestation; 4) PT difference had an area under the curve (AUC) of 0.96 (p<0.001), and a PT difference ≥1.55 had an 87% sensitivity and 90% specificity for the diagnosis of DIC; 5) the platelet count had an AUC of 0.87 (p<0.001), an 86% sensitivity and 71% specificity for the diagnosis of DIC; 6) fibrinogen concentrations had an AUC of 0.95 (p<0.001) and a cutoff point ≤3.9 g/L had a sensitivity of 87% and a specificity of 92% for the development of DIC; and 7) The pregnancy adjusted DIC score had an AUC of 0.975 (p<0.001) and at a cutoff point of ≥26 had a sensitivity of 88%, a specificity of 96%, a LR(+) of 22 and a LR(-) of 0.125 for the diagnosis of DIC. CONCLUSION: We could establish a sensitive and specific pregnancy adjusted DIC score. The positive likelihood ratio of this score suggests that a patient with a score of ≥26 has a high probability to have DIC.

Hypothyroidism and diabetes mellitus - a risky dual gestational endocrinopathy.

Objectives. Diabetes mellitus (DM) and hypothyroidism are each associated with increased rate of pregnancy complications. However, their combined morbidity during gestation is poorly studied. Therefore, the aims of this study were to determine the prevalence of the combined morbidity of DM & hypothyroidism and whether it is associated with adverse maternal and neonatal outcome. Study design. This population based retrospective cohort study included 87,213 women who had 232,293 deliveries. All deliveries were divided into the following groups: (1) hypothyroidism & DM (n = 171); (2) hypothyroidism (n = 1502); (3) DM (n = 13,324); and (4) deliveries of women with neither endocrinopathy, who served as a control group (n = 217, 296). Results. The prevalence of DM & hypothyroidism in our population was 0.17%. In comparisons to the other study groups, women with DM & hypothyroidism had higher rates of infertility (p < 0.001), preeclampsia (p < 0.001), chronic hypertension (p < 0.001), preterm birth (p < 0.001), and cesarean deliveries (p < 0.001). In Generalized Estimating Equations (GEE) model, hypothyroidism & DM was an independent risk factor for cesarean section (OR 3.46; 95% CI 2.53-4.75) and for preeclampsia (OR 1.82; 95%CI 1.16-2.84). Conclusion. The combination of DM & hypothyroidism is rare, yet it is associated with higher rate of infertility, cesarean sections, preterm deliveries, and hypertensive disorders of pregnancy than the rest of the population. This dual endocrinological combination is an independent risk factor for preeclampsia and cesarean section. These findings suggest that these patients are at risk for perinatal complications and should be followed and delivered as high risk pregnancies.

Preoperative analgesia with local lidocaine infiltration for post cesarean delivery pain management.

OBJECTIVE: To evaluate the impact of local lidocaine incision-site injection in patients undergoing cesarean deliveries (CD), on post operative pain and analgesic requirements. STUDY DESIGN: In this prospective, double-blinded, placebo-controlled study, patients undergoing elective CD were randomly assigned to receive 1% lidocaine solution or placebo to the incision site, prior to the performance of a Pfannenstiel incision. Pain intensity was evaluated for up to 48 hours after surgery and analgesic requirements of the patients were recorded. RESULTS: During the study period, 153 patients were enrolled; 77 received pre-emptive analgesia with lidocaine and 76 received a placebo. No significant differences were noted between the groups in respect to parity, previous CD, maternal age and gestational age. Pain scores or requirements of analgesia did not differ between the groups. CONCLUSION: Pre-emptive analgesia with local incision-site injection with lidocaine does not seem beneficial in reducing post cesarean pain scores and analgesic requirements.

Bacteruria with group-B streptococcus: is it a risk factor for adverse pregnancy outcomes?

OBJECTIVE: To investigate pregnancy outcomes of patients with and without group-B streptococcus (GBS) bacteriuria. METHODS: A retrospective study comparing pregnancy outcomes of women with GBS bacteriuria during pregnancy, those with positive GBS vaginal cultures and those without GBS colonization during pregnancy was conducted. RESULTS: A significant linear association was found with regard to intrapartum fever (U-GBS 0.5%, V-GBS 0.3%, no GBS 0.1%, p = 0.001) and chorioamnionitis (U-GBS 3.3%, V-GBS 1%, no GBS 0.7%, p = 0.001). In addition preterm delivery (15.3% vs. 7.9%, p = 0.001) and premature rupture of membranes (10.7% vs. 7.9, p = 0.001) were significantly higher in the U-GBS group compared to no GBS. Woman with U-GBS had higher rates of diabetes mellitus, hypertensive disorders, and habitual abortions as well as a higher risk for intrauterine growth restriction (IUGR). In addition patients with U-GBS underwent induction of labor and cesarean delivery more frequently. CONCLUSIONS: Our study showed a significant association between U-GBS and adverse obstetrical outcomes. In addition a linear association was found between GBS culture location and obstetric complications. However, GBS was not associated with adverse perinatal outcome in our population.

Routine cervical dilatation during elective cesarean delivery - Is it really necessary?

OBJECTIVE: To examine the necessity of routine cervical dilatation during elective cesarean delivery (ECD). MATERIAL AND METHODS: A retrospective cohort study including all ECD during 2005 was performed, comparing post operative complications between patients with and without cervical dilatation. RESULTS: Out of 666 ECD, 348 underwent routine cervical dilatation. No significant differences were found between the cervical dilatation and the comparison group regarding postpartum febrile morbidity (5.1 and 3.1%, respectively; p = 0.071), hospitalisation duration (4.1 +/- 1.4 and 4.1 +/- 2.0 days; p = 0.95), wound infection (0.9% and 1.25%, p = 0.451) or anemia rate (9.50 +/- 0.73 and 9.54 +/- 0.65, p = 0.91). Nevertheless, among patients following a previous vaginal delivery, cervical dilatation was significantly associated with post-operative fever (OR = 5.8; 95%CI 1.2-38.0; p = 0.021). CONCLUSION: Routine cervical dilatation during ECD does not reduce post operative morbidity. Moreover, among patients with a previous vaginal delivery cervical dilatation is a risk factor for febrile morbidity.

Sexually transmissible infections among female sex workers: an international review with an emphasis on hard-to-access populations.

BACKGROUND: Women who work commercially in sex work (female sex workers [FSW]) are considered a high-risk group for sexually transmissible infections (STI), yet the level of reported pathogens varies in studies around the world. This study reviewed STI rates reported in 42 studies of FSW around the world published between 1995 and 2006 and analysed the trends and types of populations surveyed, emphasising difficult to access FSW populations. METHODS: Studies were retrieved by PUBMED and other search engines and were included if two or more pathogens were studied and valid laboratory methods were reported. RESULTS: The five most commonly assessed pathogens were Neisseria gonorrhea (prevalence 0.5-41.3), Chlamydia trachomatis (0.61-46.2), Treponema pallidum (syphilis; 1.5-60.5), HIV (0-76.6), and Trichomonas vaginalis (trichomoniasis; 0.11-51.0). Neisseria gonorrhea and C. trachomatis were the most commonly tested pathogens and high prevalence levels were found in diverse areas of the world. HIV was highly prevalent mostly in African countries. Although human papillomavirus infection was surveyed in few studies, prevalence rates were very high and its aetiological role in cervical cancer warrant its inclusion in future FSW monitoring. Hard-to-access FSW groups tended to have higher rates of STI. CONCLUSIONS: The five most commonly detected pathogens correspond to those that are highly prevalent in the general population, however there is an urgent need to develop rapid testing diagnostics for all five pathogens to increase prevention and treatment, especially in outreach programs to the most vulnerable groups among FSW.

Sexually transmissible infections among illegal female sex workers in Israel.

Due to the mobile and clandestine nature of those who enter a country illegally, female sex workers (FSWs) who are working without papers or work permits often have no access to sexual health care. This study reports on the sexually transmissible infection (STI) prevalence among a sample of 43 sex workers working illegally. Brothel workers from republics of the Former Soviet Union (FSU), working in two locales in Israel were tested for the presence of eight pathogens and the presence of pathology by Pap smear. Of these brothel workers, 48.8% had at least one positive STI result, 14% had two STIs and one woman had three STIs. There were no cases of HIV, gonorrhoea or malignancy detected; high rates of ureaplasma (26.8%) and chlamydia were found (16.7%). Four cases of hepatitis C (9%) and three cases of hepatitis B (7%) and mycoplasma (7%) were detected. There was no relationship between reported symptoms and the detection of STIs. The level of STIs is high among this population of FSWs and it is imperative to develop more accessible health services for these women.
