Abstract
Ano-rectal incontinence is known to affect about 2% of the population. Main risk factors are traumatic delivery and previous anal surgery. All patients should have a trial of conservative treatment. Patients with major external anal sphincter defect have a 70 to 80% improvement of their symptoms after an overlap sphincter repair Unfortunately, these results deteriorate over time. Sacral nerve modulation improves continence and quality of life in 75 to 100% of patients with various aetiologies. In case of idiopathic internal sphincter degeneration, sphincter augmentation with bulking agents seems to be the least expensive option.

Abstract
The specificity of adolescent gynecology is uncontested and asks for a specific knowledge and approach. Even if the symptoms remain the same, differential diagnostic and therapeutic approach will be different, depending on the state of development (early puberty, late adolescence), during which they occur. The ignorance of specific pathologies (utero-vaginal malformation, ovarian pathologies related to the menstrual cycle) and therefore inadequate or retarded medical treatment might be the source of unnecessary sequellae. There are now many possibilities to acquire or improve one's knowledge and skills in this particular domain of gynecology. The medico-legal situation as well differs in many points from that of the adult.

Abstract
The aim of the study was to assess the effects of epidural analgesia on pelvic floor function. Eighty-two primiparous women (group 1, consisting of 41 given an epidural, and group 2 of 41 not given an epidural) were investigated during pregnancy and at 2 and 10 months after delivery by a questionnaire, clinical examination, and assessment of bladder neck behavior, urethral sphincter function and intravaginal/intra-anal pressures. The prevalence of stress urinary incontinence was similar in both groups at 2 months (24% vs. 17%, P = 0.6) and 10 months (22% vs. 7%, P = 0.1), as was the prevalence of decreased sexual vaginal response at 10 months (27% vs. 10%, P = 0.08). Bladder neck behavior, urethral sphincter function and intravaginal and intra-anal pressures showed no significant differences between the two groups. Ten months after spontaneous delivery, there were no significant differences in the prevalence of stress urinary incontinence and decreased sexual vaginal response, or in bladder neck behavior, urethral sphincter function and pelvic floor muscle strength between women who had or had not had epidural analgesia.

Abstract
Dysfunctional uterine bleeding (DUB) has emerged as one of the most frequently encountered gynecological problems. Besides the problems with anemia and iron deficiency, excessive menstrual bleeding adversely affects quality of life and contributes to health-care costs as it is a major indication for referral to the gynecological outpatient clinic. It is a disabling problem for many women and a major clinical challenge for gynecologists. There are numerous options for the treatment of DUB: drug therapy, hysterectomy, endometrial ablation with the Nd:YAG laser, resectoscope, rollerball, and more recently other alternatives such as bipolar devices, direct hot saline instillation, microwaves, and thermal balloons.

Abstract
OBJECTIVES Management of patients with atypical squamous cells of undetermined significance (ASCUS) remains controversial. We chose to repeat the Pap smear after four months. If ASCUS persisted in this second test, the patient was advised to undergo colposcopy. Our objective is to determine the clinical significance and the prediction of neoplasia among these patients through a colposcopic examination. METHODS Of 29,827 patients who had a Pap smear, ASCUS were detected in 1387 (5%) and persisted in the repeat smear of 225 (16%). Colposcopy and an additional Pap smear were performed on 186 patients. RESULTS Out of 186 colposcopic evaluations, 91 (49%) were normal and the patients had a negative Pap smear. Colposcopy was abnormal in 95/186 patients (51%) (Table 1). Histology of the directed biopsies revealed 38 (21%) low-grade squamous intraepithelial lesions (LSIL) and 17 (9%) high-grade squamous intraepithelial lesions (HSIL). Forty patients (21%) with normal biopsies had ASCUS for the third time in the Pap smear. CONCLUSIONS Colposcopic evaluation after a repeated Pap smear with ASCUS is an appropriate cost-effective management. Finding 30% of LSIL or HSIL justifies this additional investigation.

Abstract
OBJECTIVE To study the benefits of a low-dose stimulation (LDS) protocol with purified urinary follicle-stimulating hormone in patients with polycystic ovaries who have presented previously with a very high ovarian response to a standard hMG stimulation. DESIGN Cohort study. SETTING Fertility center in a university hospital. PATIENT(S) Sixty-one patients involved in an IVF/ICSI program from January 1995 to December 1996. INTERVENTION(S) The patients were first stimulated with a standard protocol using hMG and presented with a very high ovarian response. These patients were then stimulated a second time using a low-dose protocol. Cryopreserved embryos were transferred in later artificial or natural cycles until to December 1999. MAIN OUTCOME MEASURE(S) Number of gonadotropin ampules; estradiol level on the day of ovulation induction; follicles, oocytes, and cryopreserved zygotes; fertilization, implantation, and pregnancy rates; and number of ovarian hyperstimulation syndromes (OHSS). RESULT(S) The number of ampules used, the estradiol level reached, and the number of oocytes obtained were significantly lower under the LDS than the standard protocol. High implantation (21.8%) and clinical pregnancy (38.4%) rates were obtained after LDS. The cumulated deliveries per cycle started and per patient were, respectively, 41.6% and 52.5%. Five patients suffered OHSS with the standard protocol, and none with the LDS. CONCLUSION(S) The LDS protocol offers a safe and efficient treatment for patients who present with echographic polycystic ovaries and are at risk of an excessive ovarian response to standard IVF stimulation protocols.

Abstract
OBJECTIVE To assess the effect of pelvic floor education after vaginal delivery on pelvic floor characteristics in nulliparous women. METHODS We examined 107 nulliparas during pregnancy and at 9 weeks and 10 months after vaginal delivery. Methods used included a questionnaire, clinical examination, perineosonography, urethral pressure profiles, and intravaginal and intra-anal pressure recordings during pelvic floor contraction. After the second examination, the women were assigned in alternating manner to either 12 sessions of pelvic floor exercises with biofeedback and electrostimulation (n = 51) or no training (n = 56). The two groups were compared at the third examination. RESULTS Stress urinary incontinence incidence decreased in 2% of control subjects compared with 19% of women who underwent pelvic floor education (P =.002), whereas the incidence of fecal incontinence (5% versus 4%, P = 1) and the percentage of women who recovered predelivery pelvic floor contraction strength (33% versus 41%, P =.4) were no different. We observed no significant differences in bladder neck position and mobility, urethral functional length, maximal urethral closure pressure, pressure transmission ratio, residual area of continence at stress standing, or intravaginal or intra-anal pressures during pelvic floor contraction between groups at the third examination. CONCLUSION Pelvic floor education, begun 2 months postpartum, significantly reduced the incidence of stress urinary incontinence, but not fecal incontinence or weak pelvic floor. Similarly, bladder neck behavior, urodynamic characteristics, intravaginal or intra-anal pressures during pelvic floor squeezing also were not modified.

Abstract
Nasal vaccination of mice with recombinant attenuated strains of Salmonella typhimurium is more efficient at inducing antibody responses than oral vaccination. However, mortality was observed when high doses [10(9) colony forming unit (CFU)], otherwise safe by the oral route, were administered. This observation was counterbalanced by the fact that nasal vaccination was still highly efficient with lower doses (10(6) CFU), which are inefficient by the oral route and this, without any incidents of mortality. Here, we further analyse in mice the effect of nasal vaccination with differently attenuated S. typhimurium strains expressing the Hepatitis B nucleocapsid (HBc). Surprisingly, as few as 100 CFU were sufficient to induce a maximal HBc specific antibody response, but only if the bacteria were inhaled. Furthermore, we observed no correlation between the inoculum dose and the number of surviving bacteria in cervical lymph nodes and spleen. Examination of lung sections revealed strong inflammation and bronchopneumonia 24 h after nasal vaccination with 10(8) CFU, while only minor signs of inflammation were detected transiently when 10(3) CFU or phosphate buffered saline (PBS) were administered. Our data suggest that the safety issue of nasal vaccination with low doses of the Salmonella vaccine strains should be addressed in humans, as it might be an efficient alternative to oral vaccination.

Abstract
PURPOSE Our purpose was to develop a well-defined medium for the in vitro maturation (IVM) of immature bovine cumulus-oocyte complexes (COC). METHODS The COC were cultured in the presence of three protein supplementations: fetal bovine serum (FBS), bovine serum albumin, and Synthetic Serum Substitute. The embryos obtained after in vitro fertilization of IVM oocytes were cocultured with Vero cells and their development to the morula and blastocyst stages was studied. RESULTS When FBS was absent from the IVM medium, a significantly lower fertilization rate was observed, followed by a decrease in the percentage of embryos reaching the blastocyst stage. When FBS was replaced by a defined protein supplementation, the best results were obtained with Synthetic Serum Substitute. CONCLUSIONS Adequate protein supplementation of the IVM medium optimizes the fertilization rate and the development of bovine IVM oocytes. The implication of these results in the human field is discussed.

Abstract
OBJECTIVE To compare the cumulative live birth rates obtained after cryopreservation of either pronucleate (PN) zygotes or early-cleavage (EC) embryos. DESIGN Prospective randomized study. SETTING University hospital. PATIENT(S) Three hundred eighty-two patients, involved in an IVF/ICSI program from January 1993 to December 1995, who had their supernumerary embryos cryopreserved either at the PN (group I) or EC (group II) stage. For 89 patients, cryopreservation of EC embryos was canceled because of poor embryo development (group III). Frozen-thawed embryo transfers performed up to December 1998 were considered. MAIN OUTCOME MEASURE(S) Age, oocytes, zygotes, cryopreserved and transferred embryos, damage after thawing, cumulative embryo scores, implantation, and cumulative live birth rates. RESULT(S) The clinical pregnancy and live birth rates were similar in all groups after fresh embryo transfers. Significantly higher implantation (10.5% vs. 5.9%) and pregnancy rates (19.5% vs. 10.9%; P< or = .02 per transfer after cryopreserved embryo transfers were obtained in group I versus group II, leading to higher cumulative pregnancy (55.5% vs. 38.6%; P < or = .002 and live birth rates (46.9% vs. 27.7%; P< or = .0001. CONCLUSION(S) The transfer of a maximum of three unselected embryos and freezing of all supernumerary PN zygotes can be safely done with significantly higher cumulative pregnancy chances than cryopreserving at a later EC stage.

Abstract
OBJECTIVE To compare the effects of forceps delivery and spontaneous delivery on pelvic floor functions in nulliparous women. DESIGN A longitudinal prospective study with investigations during the first pregnancy, 10 weeks and 10 months after delivery. SETTING Antenatal clinic in a teaching hospital. POPULATION One hundred and seven patients aged 28 +/- 4 years, divided into those with forceps (n = 25) or spontaneous (n = 82) delivery. METHODS Investigations with a questionnaire, clinical examination, assessment of bladder neck behaviour, urethral sphincter function, intra-vaginal/intra-anal pressures during pelvic floor contractions. RESULTS The incidence of stress urinary incontinence was similar in both groups at 9 weeks (32% vs 21%, P = 0.3) and 10 months (20% vs 15%, P = 0.6) after delivery, as was the incidence of faecal incontinence (9 weeks: 8% vs 4%, P = 0.9; 10 months: 4% vs 5%, P = 1) and the decreased sexual response at 10 months (12% vs 18%, P = 0.6). Bladder neck behaviour, urethral sphincter function and intra-vaginal and intra-anal pressures were also similar in the two groups. However, 10 months after delivery, the incidence of a weak pelvic floor (20% vs 6%, P = 0.05) and the decrease in intra-anal pressure between the pre- and post-delivery values (-17 +/- 28 cm H2O vs 3 +/- 31 cm H2O, P = 0.04) were significantly greater in the forceps-delivered women. CONCLUSIONS Forceps delivery is not responsible for a higher incidence of pelvic floor complaints or greater changes in bladder neck behaviour or urethral sphincter functions. However, patients with forceps delivery have a significantly greater decrease in intra-anal pressure and a greater incidence of a weak pelvic floor.

Abstract
Dermoid cyst is the most frequent benign ovarian tumor. Its intraperitoneal rupture may lead to a peritoneal reaction known as chemical peritonitis. It is a rare but a potentially dangerous issue. Its treatment may need one or more reoperations. We report here the case of a patient operated on in emergency for a torsion of an ovarian dermoid cyst, with peritoneal spillage of its content during coeliosurgery. The prolonged contact between the sebaceous material and the peritoneum has led to a chemical peritonitis. Two more laparoscopic interventions, associated with a systemic anti-inflammatory treatment, were necessary to relieve symptoms. We propose the following attitude to avoid this complication: (1) puncture and drainage of the cyst with a trocar; (2) extraction of the cyst in an endobag, and (3) abundant washout of the peritoneal cavity.

Abstract
A total of 40 patients (mean age 51 yrs; 36-89 yrs) with clinically T1-T2(< 3 cm)N0M0 breast cancer underwent sentinel node (SN) mapping with radioactive tracer (99mTc) injection only in 21 patients, with Patent blue V in 1 patient, or with both techniques in 19 patients. The preoperative injection of 99mTc (20-40 MBq) was followed by lymphoscintigraphy. A handheld gamma probe was used to detect the SN in the operative room. A lumpectomy and an axillary dissection were performed in all the patients. SNs could be identified in 39/40 patients, resulting in a sensitivity of 98%. Successful localization of the SNs was accomplished by isotope only in 19/20 patients, by blue dye only in 1/1 patient, and by both methods in 19/19 patients; in 2 of these 19 patients, SNs were identified by blue dye only. Axillary metastases were found in 12/40 patients (30%), the SN being the only nodal metastasis in 8/12 patients (75%). Six of these 12 patients (50%) had only evidence of micrometastasis. Negative SNs on serial sections stained with hematoxylin-eosin (H&E) were evaluated with cytokeratin immunostain (C11). In all cases of negative SNs the remaining axillary nodes were also free of tumor, resulting in a negative predictive value of 100%. We conclude that SN mapping is a highly accurate method for staging the axillary node status in breast cancer patients. Optimal localization is achieved by the combination of injection of 99mTc-colloid and blue dye as evidence by the cases of positive SN identified by only one of both methods.

Abstract
BACKGROUND Cutting the cervix, morcellation, and extraction of the uterus and myomata remain major problems in endoscopic surgery. We developed an efficient, safe, reusable, and inexpensive instrument to cut the cervix and morcellate the uterus and myomata: the morcellator knife. INSTRUMENT The morcellator knife is a classic lancet with an interchangeable blade, transformed into an endoscopic instrument that can be inserted easily through a 10-mm-diameter trocar. The blade has an automatic retraction system and is set in the standby position, ensuring security. Cutting the cervix and uterine or myoma fragmentation are easy. The mass to be cut is held between two grasping forceps for easy cutting with the blade, under permanent visual control. After morcellation, extraction of the masses is performed through a posterior culdotomy. EXPERIENCE We have used this morcellator knife in 54 subtotal hysterectomies and 16 myomectomies. There were no complications during the procedures. Morcellation lasted 3-14 minutes and involved the use of an average of two to three blades. CONCLUSION The morcellator knife is a simple, safe, reusable, and inexpensive instrument with a low maintenance cost.

Abstract
OBJECTIVE To analyse the effect of differentiation on disease-free survival (DFS) and overall survival (OS) in patients with stage I adenocarcinoma of the endometrium. PATIENTS AND METHODS From 1979 to 1995, 350 patients with FIGO stage IA-IC with well (G1), moderately (G2) or poorly (G3) differentiated tumors were treated with surgery and high dose-rate brachytherapy with or without external radiation. Median age was 65 years (39-86 years). RESULTS The 5-year DFS was 88+/-3% for the G1 tumors, 77+/-4% for the G2 tumors, and 67+/-7% for the G3 tumors (P=0.0049). With regard to the events contributing to DFS, the 5-year cumulative percentage of local relapse was 4.6% for the G1 tumors, 9.0% for the G2 tumors, and 4.6% (P=0.027) for the G3 tumors. Cumulative percentage of metastasis was 1.4, 6.3 and 7.2% (P<0.001), respectively, whereas percentages of death were 6.0, 7.9 and 20.7% (P<0.001). The 5-year OS was 91+/-3, 83+/-4 and 76+/-7%, respectively (P=0.0018). In terms of multivariate hazard ratios (HR), the relative differences between the three differentiation groups correspond to an increase of 77% of the risk of occurrence of either of the three events considered for the DFS (HR=1.77, 95% CI [0.94-3.33]), (P=0.078) for the G2 tumors and of 163% (HR=2.63, 95% CI [1.27-5.43]), (P=0.009) for the G3 tumors with respect to the G1 tumors. The estimated relative hazards for OS are, respectively, in line with those for DFS: HR=1.51 (P=0.282) for the G2 tumors; and HR=3.37 (P=0.003) for the G3 tumors. CONCLUSION Patients with grade 1 tumors are those least exposed to either local relapse, metastasis, or death. In contrast patients with grade 2 tumors seem to be at higher risk of metastasis, whereas patients with grade 3 tumors appear at higher risk of death. Since we have looked at the first of three competing events (local relapse, metastasis and death), this suggests that patients with grade 3 tumors probably progress to death so fast that local relapse, if any, cannot be observed.

Abstract
In a clinical retrospective study, a follow-up of hypothalamo-amenorrheic patients treated firstly with gonadotropin-releasing hormone (GnRH) pump stimulation and secondly with human menopausal gonadotropin (hMG) was performed. Thirty-two hypothalamo-amenorrheic patients, 24-38 years old, were submitted to 103 GnRH stimulation cycles. Seven, with polycystic ovaries (PCO) on ultrasound, were stimulated with hMG after one or several unsuccessful pump cycles. Ovulation was confirmed by a luteinizing hormone (LH) surge or triggered by human chorionic gonadotropin in 80 out of 103 cycles (77.7%/cycle) leading to 62 timed sexual intercourses and 17 intrauterine inseminations (IUI). Twenty-one pregnancies (26.3%/cycle) terminated in eight abortions (38.1%/pregnancy) and 13 deliveries (40.6%/patient). hMG stimulation, in the seven PCO patients (six IVF, one IUI), led to four additional deliveries in three patients. Five patients became pregnant spontaneously after pump failure (n = 2) or unsuccessful IVF (n = 3). Combining all cycles, 17 deliveries were obtained in 16 patients. No case of ovarian hyperstimulation syndrome (OHSS) was observed. GnRH is an efficient and safe treatment of hypothalamo-amenorrheic-induced anovulation. Following GnRH or hMG ovarian stimulation, spontaneous ovulation and conception may be restored in certain hypothalamo-amenorrheic patients.

Abstract
We have recently shown that nasal immunization of anesthetized mice with human papillomavirus type 16 (HPV16) virus-like particles (VLPs) is highly effective at inducing both neutralizing immunoglobulin A (IgA) and IgG in genital secretions, while parenteral immunization induced only neutralizing IgG. Our data also demonstrated that both isotypes are similarly neutralizing according to an in vitro pseudotyped neutralization assay. However, it is known that various amounts of IgA and IgG are produced in genital secretions along the estrous cycle. Therefore, we have investigated how this variation influences the amount of HPV16 neutralizing antibodies induced after immunization with VLPs. We have compared parenteral and nasal protocols of vaccination with daily samplings of genital secretions of mice. Enzyme-linked immunosorbent assay analysis showed that total IgA and IgG inversely varied along the estrous cycle, with the largest amounts of IgA in proestrus-estrus and the largest amount of IgG in diestrus. This resulted in HPV16 neutralizing titers of IgG only being achieved during diestrus upon parenteral immunization. In contrast, nasal vaccination induced neutralizing titers of IgA plus IgG throughout the estrous cycle, as confirmed by in vitro pseudotyped neutralization assays. Our data suggest that mucosal immunization might be more efficient than parenteral immunization at inducing continuous protection of the female genital tract.

The nature of the attenuation of Salmonella typhimurium strains expressing human papillomavirus type 16 virus-like particles determines the systemic and mucosal antibody responses in nasally immunized mice.

Abstract
We have recently shown by using a recombinant Salmonella typhimurium PhoPc strain in mice the feasibility of using a Salmonella-based vaccine to prevent infection by the genital human papillomavirus type 16 (HPV16). Here, we compare the HPV16-specific antibody responses elicited by nasal immunization with recombinant S. typhimurium strains harboring attenuations that, in contrast to PhoPc, are suitable for human use. For this purpose, chi4989 (Deltacya Deltacrp) and chi4990 [Deltacya Delta(crp-cdt)] were constructed in the ATCC 14028 genetic background, and comparison was made with the isogenic PhoPc and PhoP- strains. Although the levels of expression of HPV16 virus-like particle (VLP) were similar in all strains, only PhoPc HPV16 induced sustained specific antibody responses after nasal immunization, while all strains induced high antibody responses with a single nasal immunization when an unrelated viral hepatitis B core antigen was expressed. The level of the specific antibody responses induced did not correlate with the number of recombinant bacteria surviving in various organs 2 weeks after immunization. Our data suggest that the immunogenicity of attenuated Salmonella vaccine strains does not correlate with either the number of persisting bacteria after immunization or the levels of in vitro expression of the antigen carried. Rather, the PhoPc phenotype appears to provide the unique ability in Salmonella to induce immune responses against HPV16 VLPs.

Abstract
The aim of the study was to assess and compare urethral sphincter (US) function and bladder neck (BN) behavior in pregnant and non-pregnant women. Urethral pressure profile parameters, intravaginal-anal pressures and BN position/mobility were compared in both pregnant and non-pregnant women. It was found that pregnancy results in a decreased maximal urethral closure pressure (MUCP)/area of continence at rest and at stress, decreased pressure-transmission ratio (PTR) values and backwards displacement of the bladder neck. No significant changes in intravaginal-anal pressures and BN mobility/downwards displacement were seen. Compared with stress continent pregnant patients, pregnant patients with stress urinary incontinence (SUI) have a lower MUCP at rest/stress and area of continence at stress, but show no difference in BN behavior. Regression analysis shows no correlation between advancing pregnancy and any of these parameters. It was concluded that pregnancy induces diminished US function and backwards displacement of the BN. Compared to continent pregnant patients, pregnant women with SUI also have a diminished US function. US parameters are not significantly modified by advancing pregnancy.

Abstract
OBJECTIVE To determine the effects of delivery on bladder and anorectal functions. METHODS One hundred forty-nine nulliparas were studied once during pregnancy and again about 9 weeks after delivery by means of questionnaire, clinical examination, perineal sonography, urethral pressure profiles, and recording of intravaginal and intra-anal pressures during pelvic-floor contraction. RESULTS Stress urinary incontinence was present in 46 patients (31%) during pregnancy and persisted in ten of them after delivery. After vaginal delivery, urinary and fecal incontinence were present in 36% and 4% of forceps-delivered women, respectively, and in 21% and 5.5% of spontaneously delivered women. Bladder neck mobility was increased significantly after all vaginal births, whereas bladder neck position at rest was lowered only in forceps-delivered women. Functional urethral length was decreased in the supine and standing positions after spontaneous and forceps deliveries. Otherwise, indices of urethral sphincter function were unchanged or improved after vaginal delivery. A significant decrease in intravaginal pressure and in intra-anal pressure was observed in all vaginally delivered women. The intra-anal pressure decrease correlated significantly with infant weight (r=0.24, P=.01). Women who underwent cesarean had no specific complaints and only slight modifications of these measurements. CONCLUSION After spontaneous and instrumental deliveries, 21% and 34% of women complained of stress urinary incontinence and 5.5% and 4% reported fecal incontinence, respectively. Substantial bladder neck hypermobility was present together with diminished functional urethral length and intravaginal and intra-anal pressures. Only 22% of patients with stress urinary incontinence during pregnancy had such incontinence after delivery.

Abstract
To specifically induce a mucosal antibody response to purified human papillomavirus type 16 (HPV16) virus-like particles (VLP), we immunized female BALB/c mice orally, intranasally, and/or parenterally and evaluated cholera toxin (CT) as a mucosal adjuvant. Anti-HPV16 VLP immunoglobulin G (IgG) and IgA titers in serum, saliva, and genital secretions were measured by enzyme-linked immunosorbent assay (ELISA). Systemic immunizations alone induced HPV16 VLP-specific IgG in serum and, to a lesser extent, in genital secretions but no secretory IgA. Oral immunization, even in the presence of CT, was inefficient. However, three nasal immunizations with 5 microgram of VLP given at weekly intervals to anesthetized mice induced high (>10(4)) and long-lasting (>15 weeks) titers of anti-HPV16 VLP antibodies in all samples, including IgA and IgG in saliva and genital secretions. CT enhanced the VLP-specific antibody response 10-fold in serum and to a lesser extent in saliva and genital secretions. Nasal immunization of conscious mice compared to anesthetized mice was inefficient and correlated with the absence of uptake of a marker into the lung. However, a 1-microgram VLP systemic priming followed by two 5-microgram VLP intranasal boosts in conscious mice induced both HPV16 VLP-specific IgG and IgA in secretions, although the titers were lower than in anesthetized mice given three intranasal immunizations. Antibodies in serum, saliva, and genital secretions of immunized mice were strongly neutralizing in vitro (50% neutralization with ELISA titers of 65 to 125). The mucosal and systemic/mucosal HPV16 VLP immunization protocols that induced significant titers of neutralizing IgG and secretory IgA in mucosal secretions in mice may be relevant to genital HPV VLP-based human vaccine trials.

Abstract
OBJECTIVES To validate a method for assessing urethral sphincter muscle function by recording rises in intraurethral pressure during repetitive pudendal nerve stimulations. METHODS A supine urethral pressure profile at rest was performed on 12 stress-continent and 28 stress-incontinent patients during repetitive pudendal nerve stimulations applied near the ischial spine, and the intraurethral pressure increases were calculated for each third of the urethral functional length. RESULTS No significant difference in intraurethral pressure increases was seen between continent and stress-incontinent women. On the various regression curves, the intraurethral pressure increases showed a significant correlation with maximal urethral closure pressure values at rest and at stress (r = 0.36 to 0.54) and with the patient's age (r = 0.46), but not with pudendal nerve conduction times to the urethral sphincter on either side (r = 0.14 and 0.19). CONCLUSIONS This method (1) measures intraurethral pressure increases that correlate well with the anatomic location of the urethral sphincter muscle, (2) shows there is no significant difference between them in continent and stress-incontinent patients, except in patients with a low-pressure urethra, and (3) demonstrates that they correlate well with the maximal urethral closure pressure and the patient's age, but not with pudendal motor latencies to the urethral sphincter. This method gives us a mapping of the urethral sphincter activity, explaining why some patients with a low-pressure urethra have less urinary loss than others with the same urethral closure pressure.

Abstract
OBJECTIVE To analyse the possibility of three-yearly screening for cervical cancer after two consecutive normal annual smears. METHOD Review of the literature. RESULTS In Switzerland 78% of women are screened spontaneously for cervical cancer. For 70% of this group the last smear was less than 18 months before. In other European countries or in North America programmed screening is every 3 or even 5 years. A lowered mortality rate is observed depending on the interval between screening. The benefit is only 2.7% between 3-yearly (90.8%) and yearly smears (93.5%). Finding an oncogenic HPV [16, 18, 31, 45] whilst investigating low grade cervical intraepithelial neoplasia (CIN1) is associated with a 17% risk of conversion into high grade cervical intraepithelial neoplasia (CIN3) within 3 years. CONCLUSION In Switzerland the conditions for screening on a 3-yearly basis are not fulfilled. We recommend an interval of only 2 years after 2 normal annual smears.

Abstract
Attenuated strains of Salmonella are attractive live vaccine candidates for eliciting mucosal as well as systemic immune responses. The ability to induce immune responses in the reproductive tract may be critical for the effectiveness of a prophylactic vaccine against genital human papillomaviruses (HPV), which are important etiologic agents in the development of cervical cancer. To examine the potential of a live Salmonella-based vaccine to prevent genital HPV infection, the L1 major capsid protein from HPV type 16 (HPV16) was constitutively expressed in the PhoPc strain of Salmonella typhimurium. As demonstrated by electron microscopy, the L1 protein expressed in these bacteria assembled into virus-like particles (VLPs) that resemble authentic papillomavirus virions. This is the first demonstration that papillomavirus VLPs can self-assemble in prokaryotes. BALB/c mice were immunized with the HPV16 L1 recombinant PhoPc strain by the oral and nasal routes. Despite a low stability of the L1-expressing plasmid in vivo, a double nasal immunization was effective in inducing L1-specific serum antibodies that recognized mainly native, but not disassembled, VLPs. These antibodies effectively neutralized HPV16 pseudotyped virions in an in vitro infectivity assay. Conformationally dependent anti-VLP immunoglobulin A (IgA) and IgG were also detected in oral and vaginal secretions, indicating that potentially protective antibody responses were elicited at mucosal sites. Recombinant attenuated Salmonella expressing HPV capsids may represent a promising vaccine candidate against genital HPV infection.

Abstract
OBJECTIVE This article analyses the influence of treatment duration on survival in patients with invasive carcinoma of the cervix treated by radical radiation therapy. METHOD Three hundred and sixty patients with FIGO stage IB-IIIB carcinoma of the cervix were treated in Lausanne (Switzerland) with external radiation and brachytherapy as first line therapy. Median therapy duration was 45 days. Patients were classified according to the duration of the therapies, taking 60 days (the 75th percentile) as an arbitrary cut-off. RESULTS The 5-year survival was 61% (S.E. = 3%) for the therapy duration group of less than 60 days and 53% (S.E. = 7%) for the group of more than 60 days. In terms of univariate hazard ratio (HR), the relative difference between the two groups corresponds to a 50% increase of deaths (HR = 1.53, 95% CI = 1.03-2.28) for the longer therapy duration group (P = 0.044). In a multivariate analysis, the magnitude of estimated relative hazards for the longer therapies are confirmed though significance was reduced (HR = 1.52, 95% CI = 0.94-2.45, P = 0.084). CONCLUSION These findings suggest that short treatment duration is a factor associated with longer survival in carcinoma of the cervix.

Abstract
An attenuated strain of Salmonella typhi delta(cya) delta(crp-cdt) delta(asd) expressing a gene encoding a hepatitis B virus core-pre-S protein was tested in female adult volunteers for its ability to elicit a systemic and a mucosal immune response. Specifically, our purpose was to evaluate the potential of such a vaccine strain to induce specific secretory immunoglobulin A (sIgA) at genital and rectal surfaces. Oral and rectal routes of immunization were compared: oral immunization induced seroconversion against the bacterial lipopolysaccharide (LPS) in six out of seven volunteers, while after rectal immunization only one out of six volunteers seroconverted against LPS. To our disappointment, the latter volunteer was also the only one who seroconverted against the carried antigen (pre-S1), demonstrating the poor ability of this live vaccine to induce an immune response against the carried antigen. Anti-LPS sIgA was found in both the vaginal and cervical secretions of a volunteer who presented a strong seroconversion after oral immunization (16-fold increase in anti-LPS IgG). Smaller amounts of anti-LPS sIgA were found in the rectal secretions of one orally and one rectally immunized volunteer and in the saliva of three orally and one rectally immunized woman. Our data show for the first time that it is possible to induce specific sIgA in the genital and rectal tracts of women by using an S. typhi vaccine strain.

Abstract
The case of an arterial aorto-subclavian thromboembolism associated with a moderate ovarian hyperstimulation syndrome (OHSS) and following ovulation induction for in-vitro fertilization in a young woman is reported. Because of the lack of response to systemic thrombolysis, a left postero-lateral thoracotomy was performed on day 8 after embryo transfer. A fibrinocruoric embolus situated at the junction of the left subclavian artery from the aorta was removed through a left subclavian arteriotomy. The distal axillary embolus was removed by a retrograde balloon catheter embolectomy. A moderate OHSS was observed. The ovarian stimulation and OHSS-related risks of thromboembolism are discussed. We conclude that, in the absence of risk factors, counselling about possible complications resulting from stimulation must be emphasized.

Abstract
The purpose of this study was to assess the effects of spontaneous and instrumented deliveries, the baby's birthweight, the presence of stress incontinence and the woman's age and weight on bladder neck (BN) position and mobility using perineosonography, a simple non-invasive method, and to compare these results with those from continent nulliparous controls. Two hundred and fourteen women, including 74 nullipara, 29 para-1, 64 para-2 and 3, 16 with previous forceps deliveries and 32 with stress incontinence, underwent perineosonography with measurements of BN position and backwards/downwards displacement of BN using a two-axis calculation system. Results showed that bladder neck position undergoes a significantly backwards and downwards displacement on assuming an upright position. When compared with nulliparous controls, the bladder neck position at rest was the same in all groups of parous women in the supine/standing positions, but lower in patients having undergone forceps delivery (standing position) and in stress incontinent patients (both supine and standing); the bladder neck position during Valsalva was significantly lower in all groups of patients in the standing position, but the only significant difference in the supine position was seen in stress incontinent patients; the extent of bladder neck displacement was not significantly different between the groups, except in stress incontinent patients. A strong correlation (r = 0.66) was found between the relative importance of backwards and downwards displacement, but no correlation was found between bladder neck displacement and baby's birth-weight or patient's weight. It was concluded that compared to nulliparous continent patients, normal and instrumented delivery induces no modifications of BN position at rest, but is responsible for a lower bladder neck position during Valsalva in the standing position only. The extent of BN displacement is virtually the same in all groups of patients in both positions, except for stress incontinent patients, who have a significantly lower and more mobile bladder neck, the values of which overlap to a great extent (sensitivity of 78%/75% for a displacement > 14 mm) within those seen in continent nulliparous women. The correlation between the importance of backwards and downwards displacement is strong, making superfluous a two-dimensional coordinate system for routine BN position/mobility assessment.

Abstract
The combination of mitomycin (8 mg/m(2), i.v., day 1), vindesine (3 mg /m(2), i.v., days 1 and 8), and cisplatin (60 mg/m(2), i.v., day 1) (MiViP) was evaluated in 12 patients with recurrent carcinoma of the cervix. The number of treatment courses ranged from two to eight, with a median of five. Three patients achieved complete remission and six patients showed partial remission, giving and overall response rate of 75%. The median survival was 18 months, with 22 months for responding patients, and 5 months for nonresponding patients (p < 0.01). The major toxicity was myelosuppression. We conclude that MiViP can effectively be used in recurrent carcinoma of the cervix.

Abstract
OBJECTIVE To verify the influence of age on the prognosis of cervix carcinoma. STUDY DESIGN Five hundred and sixty eight patients treated for a FIGO stage IB-IVA with radical irradiation in the Centre Hospitalier Universitaire Vaudois of Lausanne were subdivided according to the following age categories: < or = 45, 46-60, 61-69 and >70 years. Taking the 46-60 years age group as the reference, the hazard ratios (HR) of death and corresponding 95% confidence intervals (95% CI) were estimated by means of a Cox multivariate analysis. RESULTS The 5-year survival rates were, respectively, 57%, 67%, 60% and 45%. For the youngest women the risk of death was significantly increased (HR = 2.00, 95% CI [1.32-3.00]) and was even more accentuated in advanced stages. CONCLUSION Age under 45 years is a bad prognostic factor in carcinoma of the cervix.

Abstract
BACKGROUND AND OBJECTIVE A non-touch laser-induced microdrilling procedure is studied on mouse zona pellucida (ZP). STUDY DESIGN/MATERIALS AND METHODS A 1.48-microns diode laser beam is focused in a 8-microns spot through a 45x objective of an inverted microscope. Mouse zygotes, suspended in a culture medium, are microdrilled by exposing their ZP to a short laser irradiation and allowed to develop in vitro. RESULTS Various sharp-edged holes can be generated in the ZP with a single laser irradiation. Sizes can be varied by changing irradiation time (3-100 ms) or laser power (22-55 mW). Drilled zygotes present no signs of thermal damage under light and scanning electron microscopy and develop as expected in vitro, except for a distinct eight-shaped hatching behavior. CONCLUSION The microdrilling procedure can generate standardized holes in mouse ZP, without any visible side effects. The hole formation can be explained by a local photothermolysis of the protein matrix.

Abstract
The objective of this study was to analyze the effect of radiation therapy duration on event-free survival in patients with invasive carcinoma. Three hundred and sixty patients with FIGO stage IB-IIIB carcinoma of the cervix were treated with external radiation and brachytherapy as first line therapy. Median therapy duration was 45 days. Patients were classified according to whether they had rather long therapies, taking 60 days (the 75th percentile) as an arbitrary cutoff. Cumulative incidences of local recurrence, metastasis, and death were estimated. The 5-year event-free survival rate was 59 +/- 3% for the less than 60 days group and 42 +/- 7% for the more than 60 days group (P = 0.003). In terms of univariate hazard ratio (HR), the relative difference between the two groups corresponds to an increase in hazard of any of the three events considered more than the double (HR = 1.756, P = 0.003) for the longer therapy duration group. A multivariate analysis, which included selected prognostic factors, confirmed these results (HR = 1.76, P = 0.017). A short radiation therapy duration is a highly significant prognostic factor associated with longer event-free survival in carcinoma of the cervix.

Abstract
The timing of ovulation induction is usually decided according to estradiol plasma concentrations and follicle size. We administered human chorionic gonadotropin (hCG) when at least three follicles of 16 mm or more in diameter and adequate estradiol plasma concentrations were detected. We studied the percentage of mature oocyte-cumulus-corona radiata complexes, estradiol and progesterone concentrations in a heterogeneous sized follicle population (range 10-20 mm, n = 90) to perform a retrospective analysis of the adequacy of criteria adopted for the timing of ovulation induction. Plasma and follicular fluid were obtained from 20 normo-ovulating women (aged 28-37 years) treated with gonadotropin releasing hormone analogs (GnRH-a) and human menopausal gonadotropin (hMG) for in vitro fertilization (IVF). No correlation was found between the mean individual follicular fluid estradiol concentration (500-5640 nmol/l) and the respective maximum concentration in plasma (2-16 nmol/l). The estradiol concentration was similar in all follicles. Total follicular fluid estradiol concentration was found to be correlated with follicular fluid volume (r = 0.771, p < 0.01). On the day of hCG administration, the concentration of estradiol in the plasma but not the follicular fluid was correlated with the number of oocyte-cumulus-corona radiata complexes collected (p < 0.01) and the number of mature complexes (p < 0.01). At oocyte pick-up, the plasma concentration of progesterone was correlated (p < 0.01) with number of complexes collected and the number of mature complexes. The percentage of mature complexes collected (77.5%) was higher than suggested by the number of leading follicles. This indicates that our criteria for administering hCG were adequate and that heterogeneous follicle size does not exclude a high rate of mature oocyte-cumulus-corona radiata complexes.

Abstract
Breast pain or mastalgia is a frequent complaint and it may represent various pathological conditions. After a thorough evaluation and reassurance of the patients, only those whose symptoms are severe enough to alter their life-style still require therapy. In some cases it will be indicated to modify or to stop an oral contraception or to adapt a hormone replacement therapy. Those women still resistant to treatment may experience relief from evening primrose oil supplements, bromocriptine, danazol, some progestins, tamoxifen or GnRH analogues. Therapy of non cyclic breast pain is made according to the underlying pathology. If no substrate is present, treatment is the same as for cyclical mastalgia but the response is diminished.

Abstract
A case is described of an apparently healthy young woman in her first pregnancy who presented with acute pulmonary edema in the early postpartum period in the context of mild pregnancy-induced hypertension. After quick improvement in her condition, a Doppler followed by a transesophageal study revealed a left atrial septation with a small atrial septal defect secundum type and moderate mitral regurgitation strongly suggestive of a cor triatriatum sinistrum.
