Self-sampling for human papillomavirus (HPV) testing is an alternative to physician sampling particularly for cervical cancer screening nonattenders. The GRECOSELF study is a nationwide observational cross-sectional study aiming to suggest a way to implement HPV-DNA testing in conjunction with self-sampling for cervical cancer screening in Greece, utilizing a midwifery network. Women residing in remote areas of Greece were approached by midwives, of a nationwide network, and were provided with a self-collection kit (dry swab) for cervicovaginal sampling and asked to answer a questionnaire about their cervical cancer screening history. Each sample was tested for high-risk (hr) HPV with the Cobas HPV test. HrHPV-Positive women were referred to undergo colposcopy and, if needed, treatment according to colposcopy/biopsy results. Between May 2016 and November 2018, 13,111 women were recruited. Of these, 12,787 women gave valid answers in the study questionnaire and had valid HPV-DNA results; hrHPV prevalence was 8.3%; high-grade cervical/vaginal disease or cancer prevalence was 0.6%. HrHPV positivity rate decreased with age from 20.7% for women aged 25–29 years to 5.1% for women aged 50–60 years. Positive predictive value for hrHPV testing and for HPV16/18 genotyping ranged from 5.0% to 11.6% and from 11.8% to 27.0%, respectively, in different age groups. Compliance to colposcopy referral rate ranged from 68.6% (for women 25–29) to 76.3% (for women 40–49). For women residing in remote areas of Greece, the detection of hrHPV DNA with the Cobas HPV test, on self-collected cervicovaginal samples using dry cotton swabs, which are provided by visiting midwives, is a promising method for cervical cancer secondary prevention.

Background: Since continuing advances in radiotherapy technology broaden the role of radiotherapy in the treatment of gynaecologic malignancies, the use of vaginal dilators has been introduced in order to mitigate the risk of vaginal stenosis. The main aims of this study were to investigate the vaginal dilator use efficacy in the treatment of radiation-induced vaginal stenosis and the vaginal dilator effect on sexual quality of life. Methods: We studied fifty-three patients with endometrial or cervical cancer. The participants were treated with radical or adjuvant external beam radiotherapy and/or brachytherapy. They were routinely examined at four time points post-radiotherapy when also they were asked to fill in a validated sexual function-vaginal changes questionnaire. A p-value less than 0.05 was considered statistically significant. Results: The vaginal stenosis grading score was decreased and the size of the vaginal dilator comfortably insertable was gradually increased throughout the year of vaginal dilator use while radiation-induced vaginal and sexual symptoms were improved throughout the year of VD use. All patients with initial grade 3 showed vaginal stenosis of grade 2 after 12 months of vaginal dilator use and 65.8% of the patients with grade 2 initial vaginal stenosis demonstrated final vaginal stenosis grade 1 while 77.8% of the participants with initial 1st size of vaginal dilators reached the 3rd vaginal dilator size after 12 months.

Background: Human papillomavirus (HPV)-DNA testing combined with self-sampling could increase cervical cancer screening effectiveness, utilizing a sensitive screening modality and an easy sampling method with minimal pain or discomfort. Self-sampling acceptability, though, is pivotal. Materials and Methods: This study is a nested cross-sectional survey within GRECOSELF, a cross-sectional study on HPV-based screening with self-sampling, aiming at investigating self-sampling acceptability among Greek women residing in rural areas, and the factors affecting it. Women between 25 and 60 years old were recruited by midwives participating in a nationwide midwifery network. Participants, after self-sampling, filled out a questionnaire with three sections, one regarding demographic characteristics, a second with questions pertaining to the participants' cervical cancer screening history, and a third with questions regarding the self-sampling process per se. Results: The sample included 13,111 women. Most participants (67.9%), including those screened or not in the past, would prefer self-sampling if assured that the results are not inferior to standard testing. Discomfort or pain during self-sampling was absent or minimal in 97.1% and 96.5% of the cases, respectively, and 74.4% of the women felt adequately confident that they followed the instructions correctly. Women mostly preferred self-sampling at home compared with health care facilities. Pain and discomfort during the procedure, although rare, were significant factors against acceptance. Most of the women reporting a negative impression had a negative experience with conventional sampling in the past. Conclusion: Self-sampling is highly acceptable. Acceptance can be further improved with proper communication of the process and its noninferiority compared with conventional screening.

This study investigated the efficacy of a vaginal dilator (VD) for the treatment of radiation-induced vaginal stenosis (VS) and the effect of a VD on sexual quality of life. Fifty three patients with endometrial or cervical cancers participated in this prospective observational study. All participants were treated with radical or adjuvant external beam radiotherapy and/or brachytherapy. They were routinely examined 4 times after radiotherapy (RT) and were also asked to complete a validated sexual function-vaginal changes questionnaire. SPSS version 20 and Minitab version 16 were used for the statistical analysis. The statistical significance was set at P

Summary Objective Data in women regarding the role of OT in LH secretion during the LH surge are conflicting. As in previous studies blood samples for LH measurements were taken infrequently, we re-examined this matter in women with a fully characterized midcycle LH surge. Design Normal women were studied over two cycles. When the dominant follicle reached a diameter of either 16–17 mm (Group 1) or 18–19 mm (Group 2), the women were infused intravenously for 3 h with normal saline (cycle-1) or atosiban (cycle-2). Patients Fifteen women (10 in group 1 and 5 in group 2) aged 23–35 years. Measurements Blood samples were obtained every 6 h to characterize the midcycle LH surge. Results The time interval (mean ± SEM) from the start of the infusion to the onset of the LH surge in the two cycles was 46·8 ± 4·8 and 45·6 ± 9·6 h in group 1 and 6·0 ± 2·4 and 7·5 ± 2·8 h, respectively, in group 2. LH values during the LH surge were similar in the two cycles except in group 1 at the point of 30 h at which LH value in cycle-2 (41·2 ± 4·6 mIU/ml) was significantly lower than in cycle-1 (52·8 ± 3·4 mIU/ml, P

Summary Objective To study the role of oxytocin in basal and GnRH-induced gonadotrophin secretion in normal women. Design Normal women were studied in three cycles. When the diameter of the leading follicle was 15–16 mm, the women were infused intravenously (i.v.) for 3 h with normal saline (cycle 1), atosiban (cycle 2) or oxytocin (cycle 3). Patients The study included 12 normally cycling women aged 23–38 years. Measurements After cessation of treatment, two injections of GnRH, 10 µg each, were administered i.v. 2 h apart and blood samples were collected every 30 min for a total of 240 min. The 30-min pituitary response (sensitivity) to a single GnRH injection (10 µg i.v.) was investigated thereafter every 12 h from the end of the 3-h infusion until the day of LH surge onset. Results No significant differences in LH and FSH response to GnRH (sensitivity and reserve) during the 240-min experiment were found between the three cycles. The time of LH surge onset from the initiation of the infusion was similar in the three cycles. Also similar in the three cycles were oestradiol (E2) and gonadotrophin levels as well as the 30-min response to GnRH for 48 h following the 3-h infusion. Conclusions The present study demonstrates that neither exogenous oxytocin administration nor blockage of endogenous oxytocin action influences pituitary sensitivity to GnRH in cycling women.

The endogenous LH surge is the result of the estrogen-positive feedback effect. However, the factors that are responsible for the termination of LH surge are not known.The objective of the study was to investigate the mechanism that terminates the LH surge in women.Eight normally cycling women (aged 42-48 yr) were investigated in two cycles, i.e. cycle 1 (control) and cycle 2. In cycle 2 total abdominal hysterectomy plus bilateral salpingooophorectomy was performed on d 3. In both cycles, estradiol was administered transdermally at the dose of 100 microg on d 3 and 150 microg on d 4 and 5. Blood samples were obtained every 12 h from d 3 to 5 and every 6 h thereafter until d 9.In both cycles, after suppression of gonadotropins, the women displayed an endogenous LH surge. The time intervals between the commencement of estradiol treatment and the LH surge onset (73.5 +/- 1.5 vs. 76.5 +/- 2.5 h) and peak LH values (11.4 +/- 1.9 vs. 12.4 +/- 3.1 IU/liter) were comparable in the two cycles (mean +/- sem). After peaking, LH values decreased gradually in cycle 1, whereas in cycle 2 they remained stable and were higher than the corresponding values in cycle 1 (P0.05). Before the LH surge onset, estradiol values showed in both cycles a preovulatory pattern of changes, but starting 24 h after the onset of the LH surge, they were lower in cycle 2 (P0.05). Progesterone levels were similar in both cycles until the day of the LH surge onset, but in cycle 2 they declined thereafter and were lower than in cycle 1 (P0.05).It is suggested that ovarian factors rather than exhaustion of pituitary reserves are important for termination of the endogenous LH surge during the normal menstrual cycle.

This study investigated whether the GnRH antagonist ganirelix is able to block the positive-feedback effect of E2 in normal women. Ganirelix was unable to block the positive-feedback effect, suggesting that the clinical efficacy of GnRH antagonists in IVF cycles is determined by the hyperstimulation process.

A term delivery after concurrent appendectomy and salpingectomy at 6 weeks in an appendicitis coexisting with a heterotopic pregnancy after in vitro fertilization (IVF) treatment is reported.Case report.The patient presented with severe low abdominal pain at 6 weeks of pregnancy after IVF and had explorative laparotomy for appendicitis, during which she had appendectomy and salpingectomy for an undiagnosed concurrent heterotopic pregnancy. The patient delivered a 3,960 g healthy infant at 38 weeks.In patients with severe abdominal pain after IVF, appendicitis and heterotopic pregnancy should be included in the differential diagnosis. A dual pathology is possible and when treated appropriately it can result in survival of the precious intrauterine pregnancy. This is the second and earliest ever reported case of that resulted in live birth. It shows that explorative surgery must be performed timely in acute abdomen in pregnancy.
