Morbidity and chronic pain following different techniques of caesarean section: A comparative study.

Research examining long-term outcomes after childbirth performed with different techniques of caesarean section have been limited and do not provide information on morbidity and neuropathic pain. The study compares two groups of patients submitted to the 'Traditional' method using Pfannenstiel incision and patients submitted to the 'Misgav Ladach' method ≥ 5 years after the operation. We find better long-term postoperative results in the patients that were treated with the Misgav Ladach method compared with the Traditional method. The results were statistically better regarding the intensity of pain, presence of neuropathic and chronic pain and the level of satisfaction about cosmetic appearance of the scar.

Maternal smoking does not affect the amount of cell-free fetal DNA in maternal plasma during the 1st trimester of pregnancy.

CffDNA, from 344 non-smoking, 38 smoking and 33 ex-smoking pregnant women at 11 (+0)-13 (+6) gestational weeks, was extracted and quantified by the multicopy DYS14, as the fetal DNA marker and using the quantitative real-time PCR 7300 detection system. The smoking habit was based on maternal self-report, confirmed by cotinine levels and male fetuses were verified by phenotype at birth. The genders of newborns were compared with DYS14-cffDNA analysis, achieving a 100% diagnostic accuracy of the test. A total of 177 non-smokers, 18 smokers and 22 ex-smoker pregnancies with male fetuses were identified by the cffDNA concentration. Results showed that smoking status was not associated with different amounts of DYS14-cffDNA (p = 0.159), suggesting the possibility of offering cffDNA testing to all pregnant women, even if they are active smokers or ex-smokers, and the test can be unadjusted for smoking status.

Caspase 3 activation and PARP cleavage in lymphocytes from newborn babies of diabetic mothers with unbalanced glycaemic control.

Several epidemiological studies showed that gestational diabetes mellitus is the most frequent metabolic disorder of pregnancy, the pathogenesis of which has yet to be completely clarified. The aim of this study was to investigate the presence and processing of caspase 3 (Casp3) and poly(ADP-ribose) polymerase 1 (PARP1) in cord blood lymphocytes as markers of apoptosis in relation to glycaemic control during intrauterine life. Our results showed a specific positive correlation between the levels of active Casp3 (17-19 kDa) and the inactive form of PARP1 (89 kDa) in lymphocytes isolated from newborn babies of diabetic women with unbalanced glycaemic control, with a direct correlation between the activation of casp3 and the inactivation of PARP1, that makes lymphocytes unresponsive towards lipopolysaccharide stimulation, highlighting an altered functional response. Besides more studies are required to fully correlate the activation of the apoptotic process during the intrauterine life with the foetal health later in life, our study indicates that a cord blood lymphocyte, an easily accessible source, is informative about the activation of apoptotic stimuli in circulating cells of newborn babies in relation to the glycaemic control reached by the mother during pregnancy.

Role of recombinant factor VIIa in the clinical management of severe postpartum hemorrhage: consensus among European experts.

OBJECTIVES: There have been significant advances in the medical management of severe postpartum hemorrhage (sPPH) over recent decades, which is reflected in numerous published guidelines. To date, many of the currently available national and international guidelines recommend recombinant factor VIIa (rFVIIa) to be used only at a very late stage in the course of sPPH, as a "last resort", before or after hysterectomy. Based on new safety data, rFVIIa has recently been approved by the European Medicines Agency (EMA) and Swissmedic for use in sPPH, if uterotonics are insufficient to achieve hemostasis, which in fact is significantly earlier in the course of postpartum hemorrhage (PPH). We therefore aimed to develop expert consensus guidance as a step toward standardizing care with the use of rFVIIa for clinicians managing women experiencing life-threatening sPPH. METHODS: The consensus process consisted of one face-to-face meeting with a group of nine experts, including eight obstetrician-gynecologists and a hematologist highly experienced in sPPH care in tertiary care perinatal centers. The panel was representative of multidisciplinary expertise in the European obstetrics community and provided consensus opinion in answer to pre-defined questions around clinical practice with rFVIIa in the management of sPPH. Recommendations have been based on current national and international guidelines, extensive clinical experience, and consensus opinion, as well as the availability of efficacy and new safety data. RESULTS: The expert panel developed 17 consensus statements in response to the 13 pre-defined questions on the use of rFVIIa in the management of sPPH including: available efficacy and safety data and the need for interdisciplinary expertise between obstetricians, anesthesiologists, and hematologists in the management of sPPH. Based on novel data, the experts recommend: (1) earlier administration of rFVIIa in patients with sPPH who do not respond to uterotonic administration to optimize the efficacy of rFVIIa; (2) the importance of hematological parameter prerequisites prior to the administration of rFVIIa to maximize efficacy; and (3) continued evaluation or initiation of further invasive procedures according to standard practice. Furthermore, recommendations on the timing of rFVIIa treatment within the sPPH management algorithm are outlined in a range of specified clinical scenarios and settings, including vaginal delivery, cesarean section, and smaller birthing units before transfer to a tertiary care center. The panel agreed that according to available, and new data, as well as real-world experience, there is no evidence that the use of rFVIIa in patients with sPPH increases the risk of thromboembolism. The authors acknowledge that there is still limited clinical effectiveness data, as well as pharmacoeconomic data, on the use of rFVIIa in sPPH, and recommend further clinical trials and efficacy investigation. CONCLUSIONS: This expert panel provides consensus guidance based on recently available data, clinical experience, and expert opinion, augmented by the recent approval of rFVIIa for use in sPPH by the EMA. These consensus statements are intended to support clinical care for sPPH and may help to provide the impetus and a starting point for updates to existing clinical practice guidelines.

Prophylactic arterial catheterization in the management of high risk patients for obstetric haemorrhage.

OBJECTIVES: Post-partum haemorrhage still remains one of the major causes of maternal morbidity and mortality. In case of abnormal placentation it is possible to carry out preventive and therapeutic actions. To maintain fertility in reproductive-aged women and to avoid a more radical surgery, embolization has been introduced in patients at high risk for haemorrhage. To describe a new option in the management of patients with abnormal placentation by an elective, preventive arterial catheterization and selective embolization of pelvic arteries. PATIENTS AND METHODS: A retrospective study including thirty six patients with abnormal placental invasion. All patients were prepared in the angiographic room and preventive arterial catheterization was performed before elective caesarean delivery. Materials for interventional angiography were transferred to the operating room. During surgery, selective embolization of pelvic arteries was realized in case of uncontrolled bleeding. RESULTS: Thirty-six elective arterial catheterizations were performed: 4 cases (11.1%) required embolization, haemorrhage was stopped in 2 patients. Hysterectomy was performed in two cases (5.5%). No death was reported. Two humeral thrombosis (5.5%) were registered. CONCLUSIONS: Prophylactic arterial catheterization appears to be safe. The main advantage is the reduction of the interval between the onset of bleeding and the embolization. This new option of management may contribute to reduce the risk of hysterectomy and maternal death.

[Effectiveness of a new cervicometer in evaluating the risk of preterm delivery]. / Validità di un nuovo cervicometro per la valutazione del rischio di parto pretermine.

AIM: The ultrasound measurement of the cervix is the gold standard for assessing the risk of preterm delivery. We compared the accuracy of this technique with measurements obtained by the cervicometer Cervilenz®. The purpose was to show that this device can be used as a screening tool, low cost, in the diagnosis of preterm labor. METHODS: Fifty patients were included in the study at gestational age between 21+0 and 26 +0 or weeks. The study was blinded between the two performers utilizing the cervicometer and the transvaginal ultrasound. RESULTS: The study showed 100% concordance and a correlation between the two techniques of 0.94. CONCLUSION: The cervicometer proved to be a reliable and easy to use device to detect a normal or short cervix, with contained healthcare costs.

Detoxification treatment in Gynecology using a modified molded sorbent.

Postpartum endometritis is a common complication of cesarean section, the progression of which often leads to the loss of the uterus and the patient's fertility. We evaluated a detoxification therapy for treating patients with postpartum endometritis using an intrauterine application of a modified molded sorbent containing polyvinylpyrrolidone. A retrospective, controlled study included 124 patients with postpartum endometritis. The study group, n = 63, was composed of puerperae with postpartum endometritis after cesarean section, receiving antibacterial therapy in combination with the intrauterine application of a molded modified sorbent containing polyvinylpyrrolidone (FSMP) for 24 h daily for 5 days. The control group, n = 61, was composed of puerperae with postpartum endometritis after cesarean section, receiving antibacterial treatment only. The uterine cavity was infected by coccal flora (Enterococcus faecalis (26.6%), Staphylococcus spp. (21.3%), E. faecium (14.3%), and Gram-negative Escherichia coli (9.6%). A combination of these microorganisms was present in 40.5% of crops. Antibiotic resistance was detected in 53.6%-68.3% of the cases. In the study group, we observed: a faster and higher decrease in neutrophils (p < 0.05); a lower uterine concentration of pro-inflammatory cytokines: interleukin-1 beta (IL-1ß) and tumor necrosis factor α (TNFα) - 4.0 and 3.2 times, respectively, compared with the control group (p < 0.05); and a significant decrease in the uterus volume and cavity (M-echo). Using a newly modified sorbent associated with antibiotic treatment in patients with postpartum endometritis, compared with antibiotics alone, we showed a sharp reduction of inflammatory parameters, residual microorganism growth, and faster uterine volume involution. Moreover, the frequency of hysterectomy decreased by 14.4 times.

Maternal insulin-like growth factors and insulin-like growth factor-binding proteins for macrosomia prediction in diabetic and nondiabetic pregnancy: A prospective study.

OBJECTIVE: Attributable to the insulin-like growth factor (IGF) axis involvement in fetal growth regulation, possible contribution of the maternal IGF axis to antenatal fetal macrosomia diagnosis is a subject of particular interest in diabetic pregnancy. METHODS: A total of 130 women were prospectively enrolled in a longitudinal single-center cohort study. The four study groups were: type 1 diabetes (n = 40), type 2 diabetes (n = 35), gestational diabetes (n = 40), and control (n = 15). IGF-1 and IGF-2 and insulin-like growth factor-binding protein (IGFBP) 1, 3, 6, and 7 serum levels were analyzed in 11- to 14-week and 30- to 34-week samples with a specific immunoassay. RESULTS: In mothers of large-for-gestational-age neonates (90th percentile), higher (median test) first-trimester IGF-1 (P = 0.007) and lower IGFBP-1 (P = 0.035) were observed. The IGF-1/IGFBP-1 ratio was positively associated with neonatal weight (r = 0.434, P < 0.001). Receiver operating characteristic analysis revealed an association between large for gestational age and the first-trimester IGF-1 (area under the curve [AUC] = 0.747, P < 0.001), IGFBP-1 (AUC = 0.334, P = 0.011), and IGF-1/IGFBP-1 ratio (AUC = 0.750, P < 0.001). IGF-1/IGFBP-1 ratio had better performance for prediction of birth weight over 4000 g (AUC = 0.822, P < 0.001). CONCLUSION: The authors detected different first-trimester IGF-1 and IGF-1/IGFBP-1 thresholds applicable for either supposition or rejection of macrosomia diagnosis. Further investigation is needed to determine how the maternal IGF axis can contribute to fetal macrosomia prediction.

Antisepsis regimen in the surgical treatment of HPV generated cervical lesions: polyhexamethylene biguanide vs chlorhexidine. A randomized, double blind study.

INTRODUCTION: To reduce the risk of local infections after surgical treatments for HPV infected cervical lesions, the post-operative regimen is generally based on the use of vaginal antimicrobial agents. AIM: The efficacy and safety of polyhexamethylene biguanide-based vaginal suppositories was compared to a similar chlorhexidine-based treatment, in the post recovery regimen after surgical treatment of cervical lesions. MATERIALS AND METHODS: 50 women who underwent to CO2 laser therapy for cervical lesions were randomly assigned to receive 10 days of antiseptic treatment with chlorhexidine digluconate vaginal suppositories, or polyhexamethylene biguanide vaginal suppositories (Monogin®/Biguanelle® ovuli, Lo.Li. Pharma, Italy). A weekly follow-up check was performed for 6 weeks. RESULTS: Polyhexamethylene biguanide-based treatment showed improved efficacy compared to chlorhexidine, in terms of healing process and prevention of bacterial infections. CONCLUSIONS: Due to its safety and effectiveness, the vaginal treatment with polyhexamethylene biguanide is preferred to chlorexidine, in accordance with previously reported in vitro evidences.

Oxidative stress in pathological pregnancies.

Oxidative stress (OS) plays a role in pregnancy at risk of pre-eclampsia, diabetes and premature labour. We measured three markers of OS: total antioxidant capacity (TAC), thiolyte capacity and pro-oxidant capacity in 45 women: 15 normal pregnancies, 17 pathological pregnancies (pre-eclampsia and pregestational diabetes) and 13 delivered pre-term. Plasma TAC (µmol/ml) values in patients with pathological pregnancies (235.67 ± 70.08) (p(1) = 0.0086) and pre-term labour (243.51 ± 50.52) (p(2) = 0.0479) were significantly reduced as compared with the controls (306.78 ± 70.08). Thiolyte capacity (µmol/ml) in the pathological pregnancies (326.03 ± 78.24) (p(3) = 0.0029) and in pre-term labour (335.94 ± 76.63) (p(4) = 0.0084) groups were significantly reduced compared with the control group (417.48 ± 39.76) (p < 0.05). Pro-oxidant capacity (mg/100 ml) in the pathological pregnancies (94.11 ± 26.13) (p(5) = 0.00034) and in pre-term labour (87.18 ± 20.28) (p(6) = 0.00044) groups were significantly higher compared with the controls (60.27 ± 6.33). Elevated OS values were seen in pathological pregnancies. This supports the important role of OS in diseases in pregnancy, particularly pre-eclampsia, diabetes and pre-term birth.

Intrapartum sonography head transverse and asynclitic diagnosis with and without epidural analgesia initiated early during the first stage of labor.

PURPOSE: To investigate if early epidural analgesia can influence fetal head engagement into the pelvis and if it can increase the rate of transverse and asynclitic position during labour. MATERIALS AND METHODS: 195 women with combined spinal-epidural analgesia (CSE) or without neuraxial analgesia were studied. CSE was performed using a mixture of ropivacaine 0.02% with 0.3 microg/ml of sufentanil administered in the spinal space. Maintenance of analgesia was managed with intermittent epidural administration of 10-15 ml of ropivacaine (0.07%-0.10%) mixed with 0.5 microg/ml of sufentanil, based on the stage of labour and the degree of pain. 2D transabdominal ultrasound (US) was used. Serial transabdominal US examinations were performed at 45-90 min intervals to detect transverse and asynclitic positions, using the following signs: squint sign, sunset thalamus and cerebellum signs that best details the fetal head station. After delivery, the complete set of clinical and US data obtained by each examination were recorded and compared in women with and without labour analgesia. Data were examined by independent reviewers. RESULTS: There was no difference in obstetric outcome between women in whom CSE had been used and those who did not request analgesia during labour (p > 0.05). CONCLUSIONS: Epidural analgesia initiated early during labour and using low doses does not increase the rate of dystocic labors. Transverse fetal head positioning with anterior or posterior asynclitism does not seem to be promoted by drug or technique-related mechanisms, but rather should be the consequence of cephalopelvic disproportion.

[Materno-fetal conflicts and the perinatal Medea syndrome: a cognitive analysis]. / I conflitti materno-fetali e la sindrome di Medea perinatale: un'indagine conoscitiva.

The definition of "maternal-fetal conflict" requires the attribution of a well-defined subjectivity at the product of conception, and thus, from the medical point of view, we need to consider the fetus as a patient. A tangible example of conflict in our society is the "Medea syndrome", a framework in which the female parent kills her fetus or child to take revenge on the partner. We have produced a questionnaire that was administered to 150 women admitted to the Department of "Obstetrics and Gynecology" of the "Santa Maria della Misericordia" Hospital, in Perugia. The results show the importance of the maternal-fetal conflict in our reality through the opinion that women have given in assessing particular situations that we have proposed in the questionnaire.

[Identification of preterm labor: the role of the fibronectin and ultrasound cervicometry and their association]. / La identificazione del travaglio pretermine: ruolo della fibronectina e della cervicometria ecografica e loro associazione.

OBJECTIVE: The aim of this study was to evaluate the effectiveness of the fetal fibronetcin (fFN) test and ultrasonographic cervical length measurement used alone or in combination with each other in order to further improve the identification of patients in preterm labor. METHODS: Prospective multicenter observational study on patients between 24 and 32 weeks of gestation with symptoms of preterm labor (total patients = 132). The endpoint was the delivery at 34 weeks or more. The screening methods used were: the fFN test (group 1), the cervical length measurement by transvaginal ultrasound (group 2) or a combination of both tests (group 3) according to an established protocol. The statistical analysis was performed using the χ2 test using the SPSS software. RESULTS: Group 1: positive fFN test in 25.7% of cases, incidence of preterm birth (<34 weeks) of 18%. Group 2: cervical length <25 mm in 56.2% of cases, incidence of preterm birth (<34 weeks) of 18.5%. The negative predictive value is equivalent to 99.0% for the fFN test and 95.2% for cervicometry; combined use reaches 100%, compared to 54% positive predictive value. CONCLUSION: The identification of women at high risk of preterm delivery carried out with the fFN test or with transvaginal ultrasound cervicometry is clinically valid. The study also showed that the contextual use of biochemical and biophysical tests reaches a high negative predictive value (100%), making it a very useful method to identify patients truly at risk and to further reduce the incidence of non adequate treatment.

Analysis of risk factors and predictors of pregnancy loss and strategies for the management of cervical insufficiency in pregnant women at a high risk of preterm birth.

AIM: To identify risk factors and predictors of pregnancy loss and to compare the efficacy of Arabin's pessary with cervical cerclage in women at a high risk of pregnancy loss. MATERIALS AND METHODS: This was a two-center retrospective case-control study that included 240 women at a high risk of preterm delivery. Group I (n = 161) included women who underwent insertion of the Arabin's pessary between 14 and 24 weeks of pregnancy. Group II (n = 79) included women who had undergone circular cervical cerclage during the current pregnancy. All women included in the study received micronized vaginal progesterone at the dose of 200 mg/day until and including 34 weeks of gestation. RESULTS: Threatened pregnancy loss defined as spotting or vaginal bleeding in the first trimester was diagnosed in 29.8% (48/161) of patients in Group I versus 37.9% in Group II (p = .448). Postpartum bleeding occurred in 8.1% (13/161) in women in Group I versus 22.8% in Group II (χ2 = 6.500; p = .011). Our study showed that cervical cerclage was most suitable for patients with history of obstetric complications, cervical length <15 mm, and large isthmic uterine fibroids. The use of the Arabin's pessary reduced the rate of preterm births by 1.7-fold. A cluster analysis demonstrated that predictors of preterm birth in women with a high risk of pregnancy loss included: threatened pregnancy loss associated with chorionic/placental abruption, cervical incompetence, uterine fibroid growth to a large size, history of multiple spontaneous pregnancy losses, cervical tears during past labor, and gestational diabetes diagnosed for the first time during the current pregnancy. CONCLUSIONS: Women with a high risk of pregnancy loss treated with Arabin's pessary or cerclage plus vaginal progesterone had a term delivery rate of 70.4% (169/240). The combined strategy of pregnancy management allowed to markedly reduce the number of preterm births.

From Myo-inositol to D-chiro-inositol molecular pathways.

OBJECTIVE: Inositol is a carbocyclic sugar polyalcohol. By epimerization of its hydroxyl groups, nine possible stereoisomers can be generated, two of major physiological and clinical relevance: myo-inositol and D-chiro-inositol. Myo-inositol and D-chiro-inositol are normally stored in kidney, brain and liver and are necessary for functions, such as signal transduction, metabolic flux, insulin signaling, regulation of ion-channel permeability, stress response and embryo development. In this narrative review, we summarize the mechanisms by which myo-inositol and D-chiro-inositol can be synthesized and absorbed and their possible role in the etiopathogenesis of neural tube defects. MATERIALS AND METHODS: We performed an online search in the PubMed database using the following keywords: "inositol", "D-chiro-inositol", "myo-inositol", "neural tube defects and inositol". RESULTS: Inositol requirements are partly met by dietary intake, while the rest is synthesized endogenously. Inositol deficiency may be involved in the pathogenesis of diseases, such as metabolic syndrome, spina bifida (a neural tube defect), polycystic ovary syndrome and diabetes. Supplementation of the two inositol stereoisomers, D-chiro-inositol and myo-inositol is important to prevent these conditions. CONCLUSIONS: Inositol is fundamental for signal transduction in the brain, kidneys, reproductive organs and other tissues in response to neurotransmitters, hormones and growth factors. Various genes are involved in inositol metabolism and associated pathways. Altered inositol concentrations are observed in several diseases. Analysis of the genes involved in inositol metabolism may provide important information for the clinical management of these conditions.
