Abstract
BACKGROUND In the light of recent progress in pelvic organ prolapse surgery, the modalities of hospital admission need reconsidering. This work aims to assess success rate of outpatient (ambulatory) vaginal mesh surgery for genital prolapse. METHODS A prospective observational study was conducted between January 2015 and July 2017, including all patients presenting with POP-Q stage ≥3 anterior and/or apical prolapse. RESULTS Sixty-nine of the 89 eligible patients were treated on an ambulatory basis (group A); 20 required overnight admission (group B): i.e., ambulatory success rate, 77.5%. Mean operative time was 44.9±2.5 min in group A and 62±6.5 min in group B. Reasons for ineligibility for ambulatory management comprised organizational issues at home (10.5%) and excessive home-to-hospital distance (5.7%). The postoperative urinary retention rate was 4.5%. Rates for successful cystocele correction (POP-Q <2) at 2 months were similar in the two groups: 94.2% in group A and 94.4% in group B (P=ns). Mean satisfaction score was 8.6±0.3/10. CONCLUSIONS Outpatient anterior vaginal mesh surgery for prolapse is safe and effective. The current medical-economic context favors ambulatory management. Patient selection, prior information and continuity of care seem primordial.

Abstract
INTRODUCTION Patients with systemic lupus erythematosus (SLE) are at risk of cytomegalovirus (CMV) infection, due to the disease itself or to drug-induced immunosuppression. Also, active CMV infection may trigger or worsen SLE flare-up. METHODS In this retrospective single-centre cohort study, we reported all adult inpatients with a diagnosis of SLE, presenting with active and confirmed CMV infection. The goal was to describe their characteristics and outcomes (evolution of CMV infection, secondary infections and SLE flare-up), and to review the existing literature. RESULTS We identified 400 patients with confirmed SLE, including 12 who presented with active CMV infection. Severe CMV manifestations were present in 7 patients treated with immunosuppressive regimen out of 10, and in one patient out of two without immunosuppressive therapy. Six patients developed other infections, and 3 showed characterised SLE flare-up over the 3-month follow-up. All patients were alive at end of follow-up. DISCUSSION Among patients with SLE, CMV infection affected more frequently those treated with immunosuppressive drugs, but treatment-free patients were sometimes severely affected. CMV infection was associated with an increased incidence of SLE flare-up and infectious complications. Our results suggest that early anti-viral chemotherapy may be beneficial in these patients.

Abstract
Imaging of biological membranes by environmentally sensitive solvatochromic probes, such as Laurdan, provides information about the organization of lipids, their ordering, and their uneven distribution. To address a key drawback of Laurdan linked to its rapid internalization and subsequent labeling of internal membranes, we redesigned it by introducing a membrane anchor group based on negatively charged sulfonate and dodecyl chain. The obtained probe, Pro12A, stains exclusively the outer leaflet of lipid bilayers of liposomes, as evidenced by leaflet-specific fluorescence quenching with a viologen derivative, and shows higher fluorescence brightness than Laurdan. Pro12A also exhibits stronger spectral change between liquid-ordered and liquid-disordered phases in model membranes and distinguishes better lipid domains in giant plasma membrane vesicles (GPMVs) than Laurdan. In live cells, it stains exclusively the cell plasma membranes, in contrast to Laurdan and its carboxylate analogue C-Laurdan. Owing to its outer leaflet binding, Pro12A is much more sensitive to cholesterol extraction than Laurdan, which is redistributed within both plasma membrane leaflets and intracellular membranes. Finally, its operating range in the blue spectral region ensures the absence of crosstalk with a number of orange/red fluorescent proteins and dyes. Thus, Pro12A will enable accurate multicolor imaging of lipid organization of cell plasma membranes in the presence of fluorescently tagged proteins of interest, which will open new opportunities in biomembrane research.

Abstract
The unsightly excess skin located at the two ends of the scar of a mastectomy ("dog-ears"), beyond the aesthetic discomfort that they generate, can be responsible for functional impediments. These commonly occur when closing oval or circular defects. These skin excesses require then complementary resections by an incision at their base, at the cost of an extension of the original scar, sometimes during a second surgical operation. We describe a simple technique that can help to improve the cosmetic results and limit this scar ransom.

Abstract
Bartholin gland abscesses are common problems in women and their management represents a mainstay of gynecology. Various treatment methods have been described. We present a technique performed under local anesthesia, without hospitalization or postoperative care. As part of a minimally invasive approach, this procedure promotes therapeutic de-escalation, has high patient acceptance, improves clinical outcomes and reduces costs. The procedure is highlighted through an instructive video article which standardizes the essential steps, to make the technique ergonomics and easy to perform (step-by-step explanation).

Abstract
SCOPE Scope: It is well established that immune response and inflammation promote tumoral progression. Immune cells communicate through direct contact or through cytokine secretion, and it is the pro-inflammatory status that will tip the balance toward tumor progression or anti-tumor immunity. It is demonstrated here that a red wine extract (RWE) can decrease inflammation through its action on the inflammasome complex. This study determines whether an RWE could impact other key actors of inflammation, including T helper 17 (Th17) immune cells in particular. METHODS AND RESULTS Methods and results: Using an RWE containing 4.16 g of polyphenols/liter of wine, it is shown that RWE decreases colorectal cancer cells in vitro and induces a reduction in colorectal tumor growth associated with a decrease in tumor-infiltrating lymphocytes in vivo. The process of T-lymphocyte differentiation in Th17 cells is altered by RWE, as revealed by the decrease in the expression of key actors controlling this process, such as signal transducer and activator of transcription 3 and retinoid acid-related orphan receptor γt. This disruption is associated with an inhibition of inflammatory interleukin 17 secretion. CONCLUSION The data highlights the major involvement of Th17 immune cells in the biological effects of an RWE.

Abstract
Objective(s) To assess changes in quality of life after laparoscopic removal of Essure® sterilization devices (Bayer AG, Leverkusen, Germany). Study Design In this prospective observational study in an academic research hospital, 80 women with new or worsening symptoms since placement of Essure® sterilization devices undergoing subsequent surgical removal were included. Laparoscopic removal of Essure® devices and salpingectomy with or without cornual excision were performed. Concomitant uterine procedures could be associated where indicated for gynaecological complaints. Comparison using the T student test for coupled series was done in this before-and-after study. Results Health related quality of life (HRQL) was the primary outcome measured by the Short Form 12 (SF-12) questionnaire and a global 10 cm visual analogue scale (VAS). Secondary outcomes included assessment of pain, using continuous (VAS) and ordinal scales (Modified McGill Pain Questionnaire), menstrual bleeding (pictorial blood loss assessment chart (PBAC) score) and surgical feasibility and safety. There was a significant improvement in quality of life in both mental and physical health aspects of the SF-12 (34.02 (+/−1.19) vs. 49.61 (+/−1.42, P < .0001) and 36.55 (+/−0.99) vs. 43.32 (+/−1.18, P < .0001 respectively) as well as global VAS assessment (+2.91 (SD +/−0.27)) at the end of the first post-operative month. These improvements were maintained at three and six months. Mean pain decreased at one month following surgery compared to baseline (VAS 3.6 (+/−0.36) to 1.4 (+/−0.25), P < .0001 and McGill pain score 18.70 (+/−1.88) to 4.73 (+/−0.90), P < .0001). Improvements of a similar magnitude were observed when analysis was restricted to the 47 women without concomitant uterine surgery. No significant changes in bleeding were seen following of Essure® device removal. Planned procedures were all successfully completed. Conclusion Laparoscopic removal of Essure® devices in symptomatic women is technically successful and associated with short and medium-term improvement in quality of life as well as reduction in pelvic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thymus linearis, Benth indigenous to Pakistan has been traditionally used for the treatment of various diseases including hypertension. AIM OF THE STUDY Present study aims to investigate vasorelaxant effect of Thymus linearis and its underlying vasorelaxation mechanisms in porcine coronary artery rings. MATERIALS AND METHODS Aqueous-methanolic extract of aerial parts of Thymus linearis was prepared by maceration process and then bio-guided fractionation was carried out using different solvents. The effects of extract and subsequent fractions were assessed on coronary artery rings with intact and denuded endothelium. The mechanisms of vasorelaxant effect were investigated using different pharmacological tools. The in-vitro inhibitory effects of the test fractions were also assessed on purified phophodiestrases using radioenzymatic assay. Phytochemical studies were carried out using GCMS. RESULTS The aqueous-methanolic extract elicited similar relaxations in coronary artery rings with and without endothelium in dose dependent fashion and removal of endothelium did not alter this response. Further, n-butanolic fraction of Thymus liniaris (TLB) was found to be the most potent among other derived fractions. TLB did not alter the relaxation produced by endothelium dependent vasodilators in rings with intact endothelium. However, TLB significantly potentiated the relaxation elicited by cyclic AMP and cyclic GMP elevating drugs but not those to soluble guanylyl cyclase activators (YC-1 and BAY 41-2272) and K+ channel openers (levcromakalim and 1-EBIO). Pretreatment with TLB inhibited in a concentration-dependent manner contractions to KCl, CaCl2 and U46619 in coronary artery rings without endothelium. Further, TLB was found to non-selectively inhibit the PDE activity in concentration manner. CONCLUSION n-Butanolic fraction of Thymus linearis possesses endothelium independent vasorelaxant effects in coronary artery by direct acting on the smooth muscles. These effects involve the elevation of the cyclic AMP and cyclic GMP possibly through the inhibition of various PDEs. GCMS analysis revel presence of thymole and carvacrol as major constituents. Furthermore, these investigations also support the folklore use of Thymus linearis in hypertension.

Abstract
Introduction
The aim of this study is to assess the prevalence of tubal histopathological abnormalities (serous tubal intraepithelial carcinoma STIC and p53 signatures) and the prevalence of perioperative and postoperative complications related to opportunistic laparoscopic salpingectomy in a low risk population.
Materials and Methods
In this observational prospective cohort, prophylactic bilateral salpingectomy during benign laparoscopic hysterectomy was systematically performed in 100 consecutive women. Peri- and postoperative complications were registered. Duration of salpingectomy and post-salpingectomy blood loss were also measured. Histopathological and immunohistochemical analysis with anti-p53 antibody were performed on the whole fallopian tubes according to a specific and validated protocol.
Results
Laparoscopic salpingectomy was always possible without any peri- or postoperative complication attributable to the salpingectomy itself. The mean duration was 428 seconds (354 – 596) and the blood loss was 9 cm
3
(2 – 15). Using histopathological and immunohistochemical assessment with anti-p53 antibody on 199 fallopian tubes (99 bilateral salpingectomies and one unilateral salpingectomy because of previous salpingectomy for ectopic pregnancy), there was a prevalence of 5.52% (11/199) of p53 signatures. No STIC were observed and no associated cancer.
Conclusions
Laparoscopic salpingectomy is both feasible and innocuous during benign hysterectomy. Meticulous histopathologic examination of the tubes may reveal specific abnormalities.

Abstract
Background Phyllanthus amarus (Schum & Thonn), a plant belonging to the family of Euphorbiaceae is used in Ivorian traditional medicine to treat cardiovascular disorders such as hypertension. However, although this plant has been described as a diuretic agent, the underlying mechanism remains unclear. Therefore, the aim of the present study was to investigate the mechanism action of diuretic effects of an ethanolic fraction of Phyllanthus amarus (EFPA) in rats. Methods Effects of EFPA on urinary excretion were carried out for doses ranging from 5 to 80 mg/kg given by intraperitoneal injection (i.p.) and compared with that induced by furosemide (5 mg/kg) after 8 h. Thereafter, the diuretic activity of EFPA was also evaluated in the presence of indomethacin (5 mg/kg, i.p.) in order to determine the involvement of prostaglandins, after 24 h. Results Between 5 and 80 mg/kg, EFPA induced a significant urinary excretion. The profile of urinary excretion showed that after 2 h, the highest dose of 80 mg/kg induced a urinary volumetric excretion (UVE), which was similar to that induced by furosemide. After 24 h, EFPA at 10 mg/kg increased significantly UVE, Na+ (43 mEq) and Cl¯ (97 mEq) urinary excretions without promoting kaliuresis. In rats pretreated with indomethacin, the urinary excretion and the natriuretic response of EFPA were significantly reduced. Conclusion Altogether, this study has shown that EFPA promotes a significant urinary excretion of water and Na+, confirming its diuretic activity. Moreover, the increased diuresis could be attributed, at least in part, to the involvement of prostaglandins.

Abstract
OBJECTIVE To compare ovarian function before and after laparoscopic hysterectomy with bilateral salpingectomy for benign lesions with two different systems of haemostasis. METHODS In this prospective randomized study comparing two types of energy used for coagulation in bilateral salpingectomy (group A: bipolar electric energy, versus group B: ultrasonic advanced energy [Harmonic®]), forty consecutive non-menopausal patients undergoing laparoscopic hysterectomy for benign lesions were included. Values of anti-Müllerian hormone (AMH), LH and FSH, antral follicle count (AFC) and ovarian vascularization on bilateral Doppler ultrasound, quality of life (questionnaire) were assessed preoperatively and at 1 and 3 months postoperatively. RESULTS Preliminary analysis showed shorter salpingectomy operating time (P<0.0001) and less bleeding (P<0.005) in group B. In group A, there was no statistical difference except a decrease in AFC at 1 and 3 months on the right ovary (P=0.04). In group B, AMH levels were significantly lower postoperatively at 3 months and LH levels were increased at 3 months (respectively P=0.02 et P=0.04). There was no statistical difference in the ultrasonographic data. Quality of life did not significantly differ in both groups. CONCLUSION Preliminary findings showed reduced AMH levels at 3months postoperatively in ultrasonic energy group whereas there was no significative menopausal symptoms. It seems important to continue this study in order to know the real effects of both energy systems on the ovarian function.

Abstract
OBJECTIVES The recent discovery of the earliest hominin cancer, a 1.7-million-year-old osteosarcoma from South Africa has raised the question of the origin of cancer and its determinants. We aimed to determine whether malignant and benign tumors exist in the past societies. METHODS A review of literature using Medline database and Google about benign and malignant tumors in prehistory and antiquity. Only cases with morphological and paraclinical analysis were included. The following keywords were used: cancer; paleopathology; malignant neoplasia; benign tumor; leiomyoma; myoma; breast cancer; mummies; soft tissue tumor; Antiquity. RESULTS Thirty-five articles were found in wich there were 34 malignant tumors, 10 benign tumors and 11 gynecological benign tumors. CONCLUSIONS The fact that there were some malignant tumors, even few tumors and probably underdiagnosed, in the past may be evidence that cancer is not only a disease of the modern world. Cancer may be indeed a moving target: we have likely predisposing genes to cancer inherited from our ancestors. The malignant disease could therefore appear because of our modern lifestyle (carcinogens and risk factors related to the modern industrial society).

Abstract
BACKGROUND Berberis orthobotrys Bien ex Aitch. (Berberidaceae) is a plant indigenous of Pakistan that is locally used for the treatment of hypertension. HYPOTHESIS This study evaluated the vasoactive properties of a Berberis orthobotrys root extract and its fractions, and investigated the role of the endothelium and the underlying mechanism. STUDY DESIGN An aqueous methanolic extract of Berberis orthobotrys roots was prepared and submitted to a multi-step liquid-liquid fractionation with solvents of increasing polarity. Vascular reactivity of the different fractions was assessed using porcine coronary artery rings either with or without endothelium, and in the presence or absence of specific pharmacological tools. The ability of Berberis orthobotrys extracts to affect phosphodiesterase (PDE) activity was evaluated using a radioenzymatic method and purified phosphodiesterases. RESULTS The aqueous methanol extract induced similar relaxations in coronary artery rings with and without endothelium, and, amongst the three derived preparations, the butanol fraction (BFBO) was slightly but significantly more effective than the ethyl acetate fraction and the aqueous residue in rings without endothelium. Analysis of the butanol fraction (BFBO) by LC-ELSD-MS indicated the presence of four major isoquinoline alkaloids including berberine. BFBO significantly potentiated the relaxations induced by cyclic GMP- and cyclic AMP-dependent relaxing agonists, and inhibited contractions to KCl, CaCl2, and U46619 in endothelium denuded rings. In contrast, BFBO did not affect relaxations to endothelium-dependent vasodilators. BFBO concentration-dependently inhibited the cyclic GMP-hydrolyzing activity of basal PDE1, calmodulin-activated PDE1 and PDE5, and of cyclic AMP-hydrolyzing activity of PDE3 and PDE4 with IC50 values ranging from 40 to 130µg/ml. CONCLUSION The butanol fraction of the aqueous methanol extract of Berberis orthobotrys roots induced pronounced endothelium-independent relaxations and inhibited contractile responses by acting directly at the vascular smooth muscle in the coronary artery. Moreover, BFBO potentiated relaxations induced by both cyclic GMP- and cyclic AMP-dependent vasodilators most likely due to its ability to inhibit several vascular PDEs, and in particular PDE4 and PDE5.

Abstract
Endothelial dysfunction is now well established as a pivotal early event in the development of major cardiovascular diseases including hypertension, atherosclerosis, and diabetes. The alteration of the endothelial function is often triggered by an imbalance between the endothelial formation of vasoprotective factors including nitric oxide (NO) and endothelium-dependent hyperpolarization, and an increased level of oxidative stress involving several prooxidant enzymes such as NADPH oxidase and, often also, the appearance of cyclooxygenase-derived vasoconstrictors. Preclinical studies have indicated that polyphenol-rich food and food-derived products such as grape-derived products, black and red berries, green and black teas and cocoa, and omega-3 fatty acids can trigger activating pathways in endothelial cells promoting an increased formation of nitric oxide and endothelium-dependent hyperpolarization. Moreover, intake of such food-derived products has been associated with the prevention and/or the improvement of an established endothelial dysfunction in several experimental models of cardiovascular diseases and in humans with cardiovascular diseases. This review will discuss both experimental and clinical evidences indicating that different types of food and natural products are able to promote endothelial and vascular health, as well as the underlying mechanisms.

Abstract
OBJECTIVES Since the recent evidence of a tubal origin of most ovarian cancers, opportunistic salpingectomy could be discussed as a prophylactic strategy in the general population and with hereditary predisposition. We aimed to survey French gynecological surgeons about their current surgical practice of prophylactic salpingectomy. METHODS An anonymous online survey was sent to French obstetrician-gynaecologists and gynecological surgeons. There were 13 questions about their current clinical practice and techniques of salpingectomy during a benign hysterectomy or as a tubal sterilization method, salpingectomy versus salpingo-oophorectomy in the population with genetic risk, salpingectomy in relationship with endometriosis and questions including histopathological considerations. RESULTS Among the 569 respondents, opportunistic salpingectomy was always performed between 42.48% and 43.44% during laparoscopic, laparoscopic-assisted vaginal or laparotomic hysterectomy and only 12.26% in case of vaginal route. In the genetic population, salpingo-oophorectomy was mainly performed. Tubal sterilization was often practiced by the hysteroscopic route. More than 90% of respondents didn't perform salpingectomy in case of endometriosis. There was not any specific tubal histopathological protocol in 71.54% of cases. CONCLUSIONS Salpingectomy may be a preventing strategy in the low- and high-risk population. The survey's responses show that salpingectomy seems to be a current practice during benign hysterectomy for more than 40% doctors. However, there is not any change with no more salpingectomy in the population with genetic risk, or in case of endometriosis or tubal sterilization.

Abstract
Epidemiological studies have shown a relationship between endometriosis and clear cell/endometrioid ovarian cancers (named "Endometriosis Associated Ovarian Cancer" or EAOC). The recent discovery of signaling pathways (especially the SWI/SNF and PI3K/AKT/mTOR pathways) that linked endometriosis and EAOC could lead to the development of specific biomarkers as ARID1A to screen benign to premalignant endometriosis and to new targeted treatment. Moreover, the better understanding of the pathogenesis of the epithelial ovarian cancer arising from the Fallopian tube could allow new early prevention strategies that will be described in this review.

Abstract
OBJECTIVE To assess toxicity profile in two stage-IB1 cervical cancer treatment strategies: surgery with and without preoperative uterovaginal pulsed dose-rate brachytherapy. METHODS A retrospective study included 45 patients presenting stage-IB1 cervical cancer without pelvic lymph-node invasion, between 2009 and 2011: 25 treated by colpohysterectomy alone (group A) and 20 with preoperative uterovaginal pulsed dose-rate brachytherapy (group B). The median follow-up was 45 and 39 months (group A and B). RESULTS Groups were comparable for age (median, 46.9 vs 47.6 years), histologic type (52% vs 65% squamous cell carcinoma) and tumor size (68% vs 60%, <2cm). In postoperative year 1, rates of urinary, digestive and gynaecological disorder were 39.1%, 8.7% and 15% respectively in group A versus 36.8%, 5.3% and 31.6% in group B and in year 2, 5.9%, 8.4% and 15% versus 5.6%, 5.1% and 27.8%. DISCUSSION AND CONCLUSION The present study comparing two stage-IB1 cervical cancer treatment strategies found no significant difference in early or late complications. In 2 months, there was greater grade-3 urinary toxicity (21.1%) and sexual disorder (15.8%) with preoperative brachytherapy but no significant difference. Exclusive surgery is probably preferable for the patient's quality of life.

Abstract
A recent hypothesis has stated that many ovarian cancers (especially high-grade serous histotype) could arise from the distal part of the fallopian tube. On one hand we know that risk-reducing salpingo-oophorectomy is the most effective prevention for ovarian cancer among BRCA mutation carriers. On the other, oophorectomy increases the relative risk for cardiovascular, osteoporotic psychosexual and cognitive dysfunctions in premenopausal women. This raises the question whether bilateral salpingectomy could be an effective strategy in the prevention of ovarian cancer in case of hereditary predisposition and in the general population. Here we discuss origin of ovarian cancer in the light of the latest molecular studies and the relative risks and benefits of a strategy of exclusive salpingectomy in comparison with the classical adnexectomy.

Abstract
OBJECTIVE To evaluate the use of ultrasonic advanced energy in reducing the occurrence of symptomatic lymphocele and its related complications in laparoscopic extra-peritoneal para-aortic lymphadenectomy in patients with gynecological cancer. STUDY DESIGN A retrospective cohort study of consecutive patients in a tertiary referral center identified 2 groups of patients, undergoing laparoscopic extra-peritoneal para-aortic lymphadenectomy with or without the use of ultrasonic advanced energy. Surgery time, hospital stay, number of retrieved nodes and lymphocele requiring treatment were studied. Results were also compared between trained and trainee surgeons. RESULTS 163 patients were scheduled for laparoscopic extra-peritoneal para-aortic lymphadenectomy: 81 treated using bipolar energy (control group: group 1) between August 1999 and January 2005, and 82 treated using ultrasonic advanced energy (study group: group 2) between July 2010 and March 2014. The main indication (90% in group 1, 61% in group 2) was advanced cervical carcinoma (stage IB2 and above). Ultrasonic advanced energy significantly decreased operative time (p=0.001) and intra-operative bleeding (p=0.01) and increased the number of para-aortic nodes retrieved (p=0.02). There was no significant difference in hospital stay or lymphocele requiring treatment (8.6% in group 1, 8.5% in group 2: p=0.98). For senior than for junior surgeons, surgery time was shorter but not significantly (p=0.80) and postoperative lymphocele rates were identical. CONCLUSION Ultrasonic advanced energy may provide benefit in laparoscopic para-aortic lymphadenectomy, facilitating surgical ergonomics, but did not decrease post-surgery lymphocele.

Abstract
AIM OF THE STUDY Parkia biglobosa leaves are traditionally used as an antihypertensive agent in Benin. The present study assessed the vasorelaxant activity of different Parkia biglobosa leaf extracts using isolated porcine coronary artery rings. MATERIALS AND METHODS A hydroalcoholic leaf extract was submitted to a multi-step liquid-liquid fractionation with solvents of increasing polarity and the polyphenolic content of the different fractions was analyzed. Vascular reactivity of the different extracts was assessed using porcine coronary artery rings, in the presence or absence of specific pharmacological inhibitors. RESULTS The hydroalcoholic, ethyl acetate and butanolic extracts contained mainly procyanidins and monomeric flavonoids. Parkia biglobosa leaf crude extract induced a redox-sensitive endothelium-dependent relaxation mediated by both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). The fractionation of the butanolic extract generated 6 fractions, two of which induced stronger vasorelaxation than the original extract and they had a higher phenolic content. CONCLUSIONS Parkia biglobosa leaf extract is able to induce endothelium-dependent NO- and EDHF-mediated relaxation in porcine coronary artery rings. The vasorelaxant activity is dependent on their phenolic content and appears to involve mainly procyanidins.

Abstract
In the frame of cancer screening, we present a new psychological concept elaborated from our clinical practice of women affected by a breast cancer. The experience of these women is different depending on whether the cancer is discovered in an asymptomatic context or not. We introduce the concept of "anticipatrice medicine" in order to define the implication of diagnosis precocity on the therapeutic strategy, because of a modification of some main parameters which make up the ordinary personal concept. These parameters are : the time in which disease anticipates the symptom and the space where the treatment anticipates the disease. We discuss the paradoxical experience of screening which imposes a medical intervention before any symptom that is for the patient to be treated before any feeling of the disease, and to experience the disease through the experience of a treatment. The different elements of this paradoxical experience are successively identified and analysed. Finally we propose four directions of research in the field of interaction between human and medical technologies.

Abstract
OBJECTIVE A study on the feasibility and safety of a new surgical procedure of vaginal vault suspension using a polypropylene mesh placed in the uterovaginal septum by a posterior transobturator approach. PATIENTS AND METHODS Longitudinal study from March 2002 to January 2006 of patients treated by this new surgical procedure. Postoperative visits, including an interview and a physical examination were made at two, six and 12 months and annually thereafter. The minimal required follow-up time was 12 months up to January 2007. RESULTS Seventy-eight patients were included. Three cases of intraoperative bleeding occurred. In these cases no transfusion was required and no complications were observed later on. The mean hospital stay was five days (range 3-9). The mean follow-up time was 20.36 months (range 12-48). Six recurrences were observed in the medial compartment (8%) and two anterior recurrences (2%). There was no recurrence in the posterior compartment. New-onset moderate dyspareunia was noted in 13% of the cases and a severe in two cases. No erosion occurred. DISCUSSION AND CONCLUSION The analysis of our experience shows that vaginal vault suspension by posterior transobturator approach is a safe and simple procedure, and demonstrates its median efficacy. Further, this study should confirm these results over the long-term follow-up.

Abstract
We discuss collisionless electron heating in capacitive discharges excited by a combination of two disparate frequencies. By developing an analytical model, we find, contrary to expectation, that the net heating in this case is much larger than the sum of the effects occurring when the two frequencies act separately. This prediction is substantiated by kinetic simulations, which are also in excellent general quantitative agreement with the model for discharge parameters that are typical of recent experiments.

Abstract
(Z)-3,5,4'-Trimethoxystilbene is a natural polyphenol present in five different plants, Virola cuspidata, Virola elongata, Centipeda minima, Schoenus nigricans and Rheum undulatum. This molecule was prepared in a three-step sequence in good overall yield. The isomerisation from the (E)- to (Z)-isomer is performed using UV irradiation. Biological investigations were conducted on a human colon cancer cell line (Caco-2) with anti-mitotic activities. Growth was completely arrested at an added 0.4 microM level of (Z)-3,5,4'-trimethoxystilbene. This agent is 100-fold more active than resveratrol or (E)-3,5,4'-trihydroxystilbene, and the mechanism of this process involves an inhibition of tubulin polymerisation in a dose dependent manner.
