    ABSTRACT: We conducted a survey to explore levels of awareness and knowledge of HPV and cervical cancer in 170 female students and whether mode of data collection (online vs. paper) affected the results. 27% of women named HPV as a cause of cervical cancer with online respondents more likely to do so. 75% of women had heard of HPV. More online respondents had heard of HPV than paper respondents. 127 women reported having heard of HPV, with a mean knowledge score of 2.989 (SD = 1.599). Online respondents scored higher (3.57, SD = 1.316) than paper respondents (2.688, SD = 1.591). Knowledge and awareness of HPV and its link to cervical cancer appear to have increased which may be related to the HPV vaccination programme. However, there is still a considerable number of women with little to no knowledge of HPV. Online surveys may result in an inflated estimation of awareness and knowledge.

    ABSTRACT: We aimed to investigate whether conservative management of preterm premature rupture of membranes (PPROM) at 32-34 weeks' gestation improves outcome. In this retrospective analysis of singleton pregnancies, the study group included patients with PPROM at 28-34 weeks' gestation and the control group included patients presented with spontaneous preterm delivery at 28-34 weeks' gestation. Both groups were subdivided according to gestational age - early (28-31 weeks' gestation) versus late (32-34 weeks' gestation). Adverse neonatal outcome included neonatal death, intraventricular haemorrhage grade 3/4, respiratory distress syndrome, periventricular leucomalacia and neonatal sepsis. The study and control groups included 94 and 86 women, respectively. The study group had a lower incidence of adverse neonatal outcome at the earlier weeks (28-31), compared with the control group at the same gestational age. In contrast, at 32-34 weeks' gestation no difference in the risk for adverse neonatal outcome was noticed. Additionally, within the study group, chorioamnionitis rate was significantly higher among those who delivered at 32-34 weeks' gestation (p < 0.01). No advantage for conservative management of PPROM was demonstrated beyond 31 weeks' gestation. Moreover, conservative management of PPROM at 32-34 weeks' gestation may expose both mother and neonate to infectious morbidity.

    ABSTRACT: Transabdominal sonoelastography (TASE) is a new imaging technique that maps the elastic properties of soft tissue. We evaluated 34, consecutive women with suspected scar endometrioma using standard B-mode ultrasound and elastography. Twenty-three women (23/34) underwent surgical excision and had the diagnosis confirmed by histopathology. All endometriomas (23 patients) in B-mode imaging appeared as hypoechoic masses along the line of a previous caesarean section incision and the outer borders were difficult to define precisely. By TASE, the endometrioma presented a typical blue-green-red appearance and the outer borders were clearly defined. (red and green area corresponds with the central hypoechoic soft areas). Strain ratios varied from 0.02 to 0.75. Real-time TASE is a simple, useful technique in confirming a clinical diagnosis of endometrioma in a caesarean section scar. Compared with B-mode ultrasound, it provides additional, preoperative information about the extent of the lesion that may be helpful to the surgeon.

    ABSTRACT: The aim of the study was to assess serum total antioxidant capacity (TAC) and the impact of supplements on oxidative stress (OS) during pregnancy. Fifty volunteer pregnant women (21-40 years old), in the 12 ± 2 weeks' and 38 ± 2 weeks' gestation of pregnancy (study group), and 25 non-pregnant healthy women (control group) were enrolled. All pregnant women were divided into two age groups (A1: < 35 years and A2: ≥ 35 years) and four groups according to supplementation (B1: iron, B2: folic acid, B3: both and B4: none). Antioxidant activity was assayed using the TAC kit (Cayman Chemical Co.). Level of statistical significance was p < 0.05. Serum TAC values in all pregnant women in the first trimester were significantly lower, as compared with those of the control group. Levels of TAC increased significantly in the third trimester of pregnancy, especially with folic acid or no supplementation. In conclusion, pregnancy is associated with OS, which is promoted by the administration of iron supplementation.

    ABSTRACT: This retrospective study aimed to assess the efficacy of trichosanthin (TCS) in combination with or without uterine arteries embolisation (UAE), uterine curettage and sac aspiration for the treatment of caesarean scar pregnancies (CSPs). We enrolled 200 patients at 4-17 weeks' postmenstrual age with suspected CSP. CSP was diagnosed based on serum β-human chorionic gonadotropin (β-hCG) level and transvaginal ultrasound. The patients were divided into TCS group and non-TCS group, who were treated with TCS and methotrexate, respectively, in combination with UAE and uterine curettage. TCS treatment had a success rate of 96.1% (50 of 52), similar to that in non-TCS group (98.6%, 146/148). Serum β-hCG levels on days 3, 5 and 7 in TCS group were significantly decreased. The complications were fever and pain, which were alleviated with symptomatic treatment. At follow-up, all 52 patients except one case with hysterectomy from TCS treatment group had resumed normal menstruation. In conclusion, TCS combined with bilateral UAE and uterine curettage is a safe and effective treatment for CSP, especially in patients with dangerously high serum β-hCG levels.

    ABSTRACT: Pelvic organ prolapse (POP) is a debilitating condition of unknown aetiology affecting > 50% of women over 40 years of age. In POP patients, the vaginal walls are weakened allowing descent of pelvic organs through the vagina. We sought to determine if sphingosine-1-phosphate (S1P) signalling, which regulates smooth muscle contractility and apoptosis via the RhoA/Rho-kinase (ROK) pathway, is altered in the vagina of women with POP. Utilising anterior vaginal wall specimens, we provide novel demonstration of the S1P pathway in this organ. Additionally, comparing specimens from women having pelvic reconstructive surgery for POP and control subjects, we reveal increases in mRNA expression of the three major mammalian S1P receptors (S1P1-S1P3), and RhoA and the ROK isoforms: ROKα and ROKβ in POP patients, which correlates with a decrease in elastic fibre assembly pathway constituents. Taken together, our data suggest the S1P/ROK pathway as a novel area for future POP research and potential therapeutic development.

    ABSTRACT: The aim of this study was to determine the location of the appendix at the third trimester of pregnancy as there are conflicting results in literature. Distances from the base of the appendix were measured intra-operatively to the anterior iliac spine (A), symphysis pubis (B) and the xyphoid process (C). The same measurements were taken from McBurney's point on the abdominal wall (A1, B1 and C1). In the allocated 21 pregnant and 18 non-pregnant women, distance A and B were 10.3 ± 0.9 cm and 18.3 ± 3.2 cm in pregnant and 6.7 ± 0.9 cm and 13.2 ± 0.9 cm in non-pregnant women (p < 0.001), respectively. Distance C was shorter in pregnant women (14.7 ± 2.5 cm vs. 23.8 ± 1.9, p < 0.001). Conversely, distance C1 was longer in pregnant women (30.3 ± 3.0 vs. 24.8 ± 5.1 cm, p = 0.004). This study provides evidence that the appendix moves cranially late in the course of the pregnancy. Therefore, McBurney's point cannot be used as a reference point to localise the appendix at the third trimester of pregnancy.

    ABSTRACT: Prescription of postnatal thromboprophylaxis has increased with the Royal College of Obstetricians and Gynaecologists and the National Institute for Health and Care Excellence guidance. Our study of postnatal women meeting the criteria for thromboprophylaxis aimed to ascertain compliance with low-molecular-weight heparin and barriers to completion of a full course. Women were recruited from the antenatal clinic or postnatal wards. Those who agreed were contacted by telephone 14 days after delivery and asked about their compliance with and experience of thromboprophylaxis. 111 women were followed up. We found reported compliance with postnatal thromboprophylaxis to be high (83% taking the full course); most women self-injected (54%) but a significant number relied on family members (39%). Most would be prepared to take the course in a future pregnancy (94%); however, some felt that they needed more information. Reported compliance with postnatal thromboprophylaxis is high. This may be down to the motivation of the new mother, appropriate information giving and access to health care professionals for advice.

    ABSTRACT: This is a systematic review for evaluating failure rates (secondary hysterectomy or maternal mortality) and success rates (subsequent menstruation or pregnancy) following radiological or conservative surgical interventions for abnormally invasive placenta (AIP). Twelve cohort studies and 8 case series or case reports were included. The cumulative outcomes showed success rates of 159/177 (89.8) for arterial embolisation, a secondary hysterectomy in 20/177 (11.3%), a subsequent menstruation in 74/85 (87.1%) and a subsequent pregnancy in 3/10 (30%). Artery occlusion balloon presented a success rate of 33/42 (78.6%), and a secondary hysterectomy presented that of 8/42 (19%). Uterus-preserving surgery showed a success rate of 48/76 (63.2), a secondary hysterectomy in 23/76 (30%), maternal mortality in 2/54 (3.7%), a subsequent menstruation in 20/37 (81.1%) and a subsequent pregnancy in 21/27 (77.8%). This review indicates that different uterine-sparing radiological and surgical techniques may be effective in managing AIP in select patients.
