Abstract
INTRODUCTION AND OBJECTIVES Artificial urinary sphincter (AUS) is a treatment option for women with stress urinary incontinence (SUI) after failure of previous surgery or as a primary procedure in severe intrinsic sphincter deficiency (ISD). The aim of the study was to assess the long-term efficacy and risk factors for surgical revision and definitive explantation of AUS laparoscopic implantation in female patients. METHODS A retrospective review of all women submitted to AUS implantation between April 2005 and March 2023 was conducted. The AUS was implanted via transperitoneal laparoscopic approach, by two experienced surgeons. The primary endpoint was postoperative continence. Continence was defined as no leakage and no pad usage or leakage and/or pad usage with no impact on social life and failure as leakage and/or pad usage impacting social life. As secondary outcomes, clinical predictive factors for AUS revision and definitive explantation were evaluated. RESULTS In the last 18 years, females with a mean age of 68±12 years-old were submitted to laparoscopic implantation of AUS. Early overall complication rate was 16%, but only one case was Clavien-Dindo ≥3. After a median follow-up of 67 months, 22.2% of the patients needed a device revision, the majority due to mechanical device dysfunction. AUS definitive explantation was performed in 16%, mainly due to urethral/vaginal erosion (9.9%) and infection (6.2%). Patients with age ≥70 years and follow-up ≥10 years significantly predisposed for device revision. At the time of the last follow-up, 72% of the patients were keeping the urinary continency. CONCLUSIONS Laparoscopic AUS implantation in females is an effective treatment for SUI due to ISD. Meanwhile, adequate patient selection, multidisciplinary evaluation and careful expectation management are essential to achieving good results, concerning their significant complication rate.

Abstract
Charge density wave (CDW) order has been shown to compete and coexist with superconductivity in underdoped cuprates. Theoretical proposals for the CDW order include an unconventional d-symmetry form factor CDW, evidence for which has emerged from measurements, including resonant soft x-ray scattering (RSXS) in YBa2Cu3O6+x (YBCO). Here, we revisit RSXS measurements of the CDW symmetry in YBCO, using a variation in the measurement geometry to provide enhanced sensitivity to orbital symmetry. We show that the (0 0.31 L) CDW peak measured at the Cu L edge is dominated by an s form factor rather than a d form factor as was reported previously. In addition, by measuring both (0.31 0 L) and (0 0.31 L) peaks, we identify a pronounced difference in the orbital symmetry of the CDW order along the a and b axes, with the CDW along the a axis exhibiting orbital order in addition to charge order.

Abstract
Abstract
Background
Endothelin Receptor Antagonists (ERAs) have been investigated for the treatment of a variety of cardiovascular conditions because of their potent vasodilating properties. However, until now, ERAs have only been registered for the treatment of pulmonary arterial hypertension and scleroderma-induced digital ulcers. This class of drugs may also be useful in the treatment of difficult to control hypertension with a medical need.
Purpose
To investigate the efficacy and safety of various doses of the new dual ERA, aprocitentan, in the treatment of hypertension in order to determine the most appropriate dose(s) for further clinical development using an unattended, automated office BP (AOBP) device (BpTRU). This Phase 2 trial was registered at ClinicalTrials.gov [NCT02603809].
Methods
Eligible patients with hypertension (mean sitting systolic/diastolic BP 149.7/97.6 mmHg) received aprocitentan 5, 10, 25 or 50 mg, matching placebo or lisinopril 20 mg as a positive control, once daily for 8 weeks using a randomised, double-blind, parallel-group study design. AOBP was assessed at baseline and weeks 2, 4, 8, and 10 (withdrawal) by recording multiple BP readings with the patient resting quietly. Additionally, 24 h ambulatory BP monitoring was performed at baseline and week 8.
Results
A total of 490 eligible patients were randomised to the double-blind phase with 430 subjects successfully completing 8 weeks of treatment. Decreases in sitting systolic/diastolic AOBP, from baseline to week 8 were 10.3/6.3, 15.0/9.9, 18.5/12.0 and 15.1/10.0 mmHg for aprocitentan 5, 10, 25, and 50 mg, respectively vs. 7.7/4.9 mmHg for placebo and 12.8/8.4 mmHg for lisinopril. No changes in heart rate or body weight were observed for any dose of aprocitentan.
Modelling the dose-response suggested that the maximal effect of aprocitentan is achieved at a dose of approximately 25 mg and that 70% of this effect is already observed at a dose of 10 mg. Aprocitentan treatment was associated with decreases in haemoglobin, haematocrit, and albumin which exhibited a monotonic dose-response relationship, in line with its known vasodilating effects. Estimated increases in plasma volume were 3.0%, 5.1%, 6.9%, and 9.5% for aprocitentan 5, 10, 25, and 50 mg, respectively, vs. 1.6% for lisinopril and a decrease of 0.3% for placebo. All these values are below the accepted pathophysiological threshold of 10%.
The overall incidence of adverse events observed in the aprocitentan groups (ranging from 22.0% to 40.2%) was similar to that seen in the placebo group (36.6%). Overall, the most common events were hypertension, headache, and nasopharyngitis.
Conclusions
These findings support the use of aprocitentan at doses between 10 and 25 mg for further investigation as a potential treatment for hypertension.

Abstract
BACKGROUND Furosemide is the only loop diuretic recommended by the ACVIM consensus guidelines for treatment of congestive heart failure (CHF) in dogs related to degenerative mitral valve disease (DMVD). Torasemide is another potent loop diuretic with a longer half-life and a higher bioavailability. OBJECTIVES (1) To demonstrate that torasemide given once a day (q24h) is noninferior to furosemide given twice a day (q12h) for treating dogs with CHF; (2) and to compare the effect of the 2 drugs on the time to reach a composite cardiac endpoint "spontaneous cardiac death, euthanasia due to heart failure or CHF class worsening." ANIMALS A total of 366 dogs with CHF attributable to DMVD. METHODS Analysis of 2 prospective randomized single-blinded reference-controlled trials was performed. Dogs orally received either torasemide q24h (n = 180) or furosemide q12h (n = 186) in addition to standard CHF therapy over 3 months. The primary efficacy criterion was the percentage of dogs with treatment success assessed in each study. The time to reach the composite cardiac endpoint was used as secondary criterion in the overall population. RESULTS Torasemide was noninferior to furosemide (Ptorasemide - Pfurosemide = +7%; 95% CI [-8%; +22%] and Ptorasemide - Pfurosemide = +1%; 95% CI [-12%; +14%], respectively, in Study 1 and Study 2). Torasemide (median dose = 0.24 mg/kg/d q24h; range = 0.10-0.69 mg/kg/d) was associated with a 2-fold reduction in the risk of reaching the composite cardiac endpoint (adjusted HR = 0.47; 95% CI = 0.27-0.82; P = 0.0077) as compared with furosemide (median dose = 1.39 mg/kg q12h; range = 0.70-6.30 mg/kg q12h). CONCLUSIONS AND CLINICAL IMPORTANCE Torasemide q24h is an effective oral diuretic in dogs with CHF.

Abstract
OBJECTIVES To analyze the safety and the mid-term continence rates of laparoscopic implantation of artificial urinary sphincter in women. METHODS A total of 52 women with intrinsic sphincter deficiency underwent a laparoscopic artificial urinary sphincter implantation from 2005 to 2015 at Surgical Clinic Du Pré, Le Mans, France. The artificial urinary sphincter was implanted around the bladder neck by a transperitoneal laparoscopic approach to the Retzius space. Urodynamic assessment was carried out. Postoperative functional outcome was defined as success (no leaking, no pad use), improvement (>50% decrease in number of leakages, >50% decrease in number of pads used or use of light protection) or failure (<50% improvement, persistent or increased leaking). Outcome measures also included perioperative and long-term complications. RESULTS The mean age of the patients was 69.1 years (range 64-82 years). After a mean follow up of 37.5 months (median 24 months; range 1-125 months), 38 (77.6%) patients were considered to be continent (no leakage, no pads), and eight (16.3%) improved their grade of incontinence. Three patients abandoned the follow-up schedule and were excluded. There was no perioperative severe complication. Artificial urinary sphincter revision was needed in 11 (22.4%) patients, requiring a total of seven redo procedures and four permanent sphincter removals. The main reasons for redo procedures were six (11.2%) mechanical problems and one vaginal erosion (2%). CONCLUSIONS Herein we report one of the largest series with the longest follow up evaluating the outcomes of laparoscopic artificial urinary sphincter implantation in female patients. This approach seems to be a safe and effective treatment option for patients with intrinsic sphincter deficiency.

Abstract
PURPOSE The prostate cancer (PCa) treatment is multimodal. Thus multidisciplinary team management (MDTM) decision-making process appears as a tool to answer all aspects of PCa treatment. Our aim was to evaluate the reproducibility of therapeutic decisions made at MDTM. MATERIALS AND METHODS We compared therapeutic decisions of PCa by presenting the same file of patient under a fake identity after 6 to 12 months from the first presentation. Forty-nine files of radical prostatectomy (RP) (28 pT2, 21 pT3) performed for clinical localized PCa were represented at MDTM which included urologist, oncologist, pathologist and radiologist. Analysis of therapeutic decisions comprised criteria such as: TNM stage, Gleason score, margin status and comorbidities. The reproducibility was assessed statistically by Kappa coefficient. RESULTS Study subjects included 49 patients who underwent radical prostatectomy (RP). The mean age was similar in pT2 and pT3 groups (P = .09). The mean serum PSA value was 8.32 ng/mL (range, 3.56-19.5) in pT2 group and 9.4 ng/mL (range, 3.8-22) in pT3 group. The margin status in pT2 and pT3 groups was positive in 25.0% and 47.6%, respectively. The decisions made at first and second MDTM for pT2 group were the same in 100% of cases with a perfect kappa coefficient (k = 1). In the group of pT3 (n = 21), the decisions were different in 33% at the second MDTM in comparison to the first MDTM. Especially for pT3b only 29% were reproducible decision with a slight agreement (k = 0.1). Concerning pT3a, 86% of the decisions were reproducible with a substantial agreement (k = 0.74). CONCLUSION We showed a reliability and reproducibility of decision made at MDTM when guidelines are well defined. The therapeutic attitudes were less reproducible in locally advanced PCa but decision concerning those cases should be made in the setting of guidelines.

Abstract
OBJECTIVE To analyze patients' views with regards to local consultations given by specialists in urology and to an offer of pre- and postoperative visits in the local general hospital with surgical interventions taking place at the university hospital. MATERIALS AND METHODS An opinion survey by mail questionnaire was carried out in all 473 patients who had had a consultation with a specialist in two local general hospitals between November 2009 and April 2010. RESULTS Response rate was 74%. Mean patient age was 65.5 ± 12 years [range, 20-90]. The reason for the consultation was cancer-related in 31.2% of patients. The majority (89%) made the journey to hospital under their own steam and would have had to travel a 4 times greater distance if the consultation with the specialist had taken place at the university hospital. Overall, 54.6% of patients were willing to travel 20 km further to see a specialist and 76.5% were willing to travel 20 km further for a surgical intervention. Virtually all of the patients (>99%) saw benefits to local consultations given by specialists. The offer of a consultation at the general hospital and intervention at the university hospital met with the approval of 60.8% patients and 56.3% had already experimented this offer. CONCLUSION Local consultations by specialists might be an answer to demographic issues in France, that is, to the small number of urologists practicing in general hospitals.

Abstract
INTRODUCTION Women in Haiti and throughout the Haitian Diaspora shoulder a disproportionate burden of cervical cancer morbidity and mortality. The widespread Human Papillomavirus (HPV) vaccination holds promise for helping to attenuate this disparity. However, previous research has not fully examined Haitian women's perceptions of, and barriers to, HPV vaccination, which is essential for informing future intervention. The current paper aims to fill this gap. METHODS As part of ongoing Community-Based Participatory Research (CBPR) efforts, we conducted a series of focus groups with Haitian immigrant women in Little Haiti, the predominantly Haitian neighborhood in Miami, Florida, U.S. Focus group questions assessed women's knowledge and beliefs about cervical cancer and HPV, their opinions of vaccines in general, their knowledge and perceptions of the HPV vaccine specifically and health communications preferences for cervical cancer prevention. RESULTS Among the participants who had heard of HPV, many held misconceptions about virus transmission and did not understand the role of HPV in the development of cervical cancer. Virtually all participants expressed support for vaccines in general as beneficial for health. Some women had heard of the HPV vaccine, primarily as the result of a contemporary popular media campaign promoting the Gardasil® vaccine. Physician recommendation was commonly mentioned as a reason for vaccination, in addition to having more than one sex partner. Women felt the HPV vaccine was less appropriate for adolescent girls who are presumed as not sexually active. Women indicated a strong preference to obtain health information through trusted sources, such as Haitian physicians, Haitian Community Health Workers, and especially Kreyol-language audiovisual media. DISCUSSION Study findings indicate a need for culturally and linguistically appropriate educational initiatives to promote awareness of HPV and its role in cervical cancer, the importance of vaccination against the virus, explicitly differentiating HPV from HIV and providing specific information about vaccine safety. CONCLUSION In the U.S., there is a substantial lack of educational information available in Haitian about HPV and cervical cancer. This gap results in missed opportunities to promote disease prevention through vaccination and regular screening. Addressing such gaps is essential for achieving health equity among Haitian immigrant women and other, similarly underserved women, who are disproportionately burdened by cervical cancer.

Abstract
This paper describes techniques for measuring halo currents, and their associated toroidal peaking, in the National Spherical Torus Experiments [M. Ono et al., Nucl. Fusion 40, 557 (2000)]. The measurements are based on three techniques: (1) measurement of the toroidal field created by the poloidal halo current, either with segmented Rogowski coils or discrete toroidal field sensors, (2) the direct measurement of halo currents into specially instrument tiles, and (3) small Rogowski coils placed on the mechanical supports of in-vessel components. For the segmented Rogowski coils and discrete toroidal field detectors, it is shown that the toroidal peaking factor inferred from the data is significantly less than the peaking factor of the underlying halo current distribution, and a simple model is developed to relate the two. For the array of discrete toroidal field detectors and small Rogowski sensors, the compensation steps that are used to isolate the halo current signal are described. The electrical and mechanical design of compact under-tile resistive shunts and mini-Rogowski coils is described. Example data from the various systems are shown.

Abstract
PURPOSE Patients with permanent cardiac pacemakers occasionally require radiotherapy. Therapeutic irradiation may cause pacemakers to malfunction due to the effects of ionizing radiation or electromagnetic interference. We studied the breast cancer patients who needed breast and/or chest wall and lymph node irradiation to assess the feasibility and tolerance in this population of patients. PATIENTS AND METHODS From November 2008 to December 2009, more than 900 patients received radiotherapy for their breast cancer in our department using megavoltage linear accelerator (X 4-6 MV and electrons). Among them, seven patients were with permanent pacemaker. All patients have been treated to the breast and chest wall and/or lymph nodes. Total dose to breast and/or chest wall was 50 Gy/25 fractions and 46 Gy/23 fractions to lymph nodes. Patients who underwent conserving surgery followed by breast irradiation were boosted when indicated to tumour bed with 16 Gy/8 fractions. All patients were monitored everyday in presence of radiation oncologist to follow the function of their pacemaker. All pacemakers were controlled before and after radiotherapy by the patients' cardiologist. RESULTS Seven patients were referred in our department for postoperative breast cancer radiotherapy. Among them, only one patient was declined for radiotherapy and underwent mastectomy without radiotherapy. In four cases the pacemaker was repositioned before the beginning of radiotherapy. Six patients, aged between 48 and 84 years underwent irradiation for their breast cancer. Four patients were treated with conserving surgery followed by breast radiotherapy and two with mastectomy followed by chest wall and internal mammary chain, supra- and infra-clavicular lymph node irradiation. The dose to the pacemaker generator was kept below 2 Gy. There was no pacemaker dysfunction observed during the radiotherapy. CONCLUSION The multidisciplinary work with position change of the pacemaker before radiotherapy and everyday monitoring permitted the safe treatment of our patients. Updated guidelines are definitely needed with more details about acceptable doses at the different parts of the pacemaker.

Abstract
The best surgical option for the management of severe cases of Peyronie's disease is currently a matter of debate. To determine medium-term outcomes and complications after treatment of severe Peyronie's disease by porcine small intestinal submucosa (SIS) grafts, we retrospectively reviewed 33 consecutive plaque incisions followed by 4-ply SIS grafting in 28 patients (2002-2009). Postoperative complications, penile length preservation, de novo ED, penile curvature correction and curvature recurrence rates were recorded. Median patient age was 54 years (38-69 years). Median preoperative curvature was 90° (30-90°) (stable for at least 6 months). Six patients (21%) had preoperative ED. There were few postoperative complications (no cases of infection, haematoma (n=2), penile hypoesthesia (n=1), patch rejection and migration (n=1)). Subjective penile shortening and de novo ED were observed in 7 (25%) and 3 (11%) patients, respectively. The success rate for the procedure (straight penis or curvature ≤20° and ability to have intercourse) was 67% (22/33). Four patients achieved curvature correction after a repeat procedure with a new SIS graft. Eleven patients experienced recurrence within 3 months of surgery. After a median follow-up of 9 months (3-94), 22 patients (79%) had a satisfactory curvature correction.

Abstract
OBJECTIVE To assess the value of endothelin-1 (ET-1) expression in predicting extracapsular extension (ECE) in clinically localized prostate cancer (PCa). PATIENTS AND METHODS ET-1 expression was determined by immunohistochemistry on archival needle biopsies (NBs) from 94 patients (49 pT2 and 45 pT3a) who underwent radical prostatectomy (RP) for clinical T1-T2 PCa. Each sample was analysed independently by two pathologists blinded to the clinical data. RESULTS In univariate analysis, high ET-1 expression in NBs, pre-operative prostate-specific antigen (PSA) level >10 ng/ml, percentage of positive biopsy cores and NB Gleason score ≥7 were significantly associated with ECE as determined on subsequent RP. No significant association was found between clinical stage and ECE. In multivariate analysis, there was a significant association with high ET-1 expression in NBs (p = 0.006), pre-operative PSA level >10 ng/ml (p = 0.049), and NB Gleason score ≥7 (p = 0.002). These three pre-operative factors combined provided the best model for predicting ECE with 93.3% sensitivity, 49% specificity, 62.5% positive predictive value, 88.9% negative predictive value. The combination yielded a higher concordance index (0.760 vs 0.720) and offered a higher log partial likelihood than the same model without ET1 (112.8 vs 105.7, p = 0.01). CONCLUSIONS ET-1 expression was strongly associated with ECE and, when combined with pre-operative PSA level and Gleason score, improved the predictive accuracy of pre-operative NBs. Its assessment in patients with localized PCa might be useful when making treatment decisions. Further studies with standardisation of immunohistochemical staining and multi-institutional validation are now needed to establish the appropriate use of ET-1 staining in PCa staging and to evaluate inter-observer reproducibility.

Abstract
The lithium tokamak experiment (LTX) is a modest-sized spherical tokamak (R(0)=0.4 m and a=0.26 m) designed to investigate the low-recycling lithium wall operating regime for magnetically confined plasmas. LTX will reach this regime through a lithium-coated shell internal to the vacuum vessel, conformal to the plasma last-closed-flux surface, and heated to 300-400 °C. This structure is highly conductive and not axisymmetric. The three-dimensional nature of the shell causes the eddy currents and magnetic fields to be three-dimensional as well. In order to analyze the plasma equilibrium in the presence of three-dimensional eddy currents, an extensive array of unique magnetic diagnostics has been implemented. Sensors are designed to survive high temperatures and incidental contact with lithium and provide data on toroidal asymmetries as well as full coverage of the poloidal cross-section. The magnetic array has been utilized to determine the effects of nonaxisymmetric eddy currents and to model the start-up phase of LTX. Measurements from the magnetic array, coupled with two-dimensional field component modeling, have allowed a suitable field null and initial plasma current to be produced. For full magnetic reconstructions, a three-dimensional electromagnetic model of the vacuum vessel and shell is under development.

Abstract
OBJECTIVES To assess the impact of RP on patients' sexual desire and orgasm. MATERIAL AND METHODS Prospective, cross-sectional survey using a 16-item self-administered questionnaire. We assessed relevant domains of male sexual function (erectile function, sexual desire, and orgasm), psychological impact and treatment of ED. RESULTS A total of 63 consecutive patients after RP were included (mean age: 63.9). Median time between questionnaire and RP was 26.8 months (range 6-67). After RP, 74.6 % of patients used ED treatments. Lower sexual desire and intercourse frequency were reported in respectively 52.4 and 79.4 %. Orgasm was modified in most patients: 39.7 % described loss of orgasm and 38.1 % reported decreased intensity. Involuntary loss of urine at orgasm (climacturia) was reported in 25.4 %. Negative psychological impact was reported in 68.3 % (loss of self-esteem, loss of masculinity, anxiety). CONCLUSIONS RP adversely affected erectile and orgasmic functions but also sexual desire, self-esteem and masculinity despite treatments. Candidates for RP should be aware of ED but also of other postoperative sexual dysfunctions.

Abstract
AIM The study evaluated the immunohistochemistry expression of endothelin-1 (ET-1) by prostate cancer (PCa) in prostate biopsies as an extracapsular stage (pT3a) prognostic factor. MATERIAL AND METHOD Sixty-eight radical prostatectomies (RP) were performed for clinically localised PCa (35 pT2 and 33 pT3a according to the 2002 pTNM classification). Age, digital rectal examination, initial PSA, biopsy Gleason score, positive biopsies ratio, specimen Gleason score, biopsy and RP specimen perineural neoplasic invasion, PCa DNA ploidy, PCa Ki-67 DNA image cytometry and biopsy and RP specimen ET-1 immunohistochemistry expression for both group were compared. Semi-quantitative ET-1 staining assessment was realised by the same pathologist. RESULTS pT3a group initial PSA was higher (p=0.032). No statistically difference was noticed between pT2 and pT3a groups for positive biopsies ratio, biopsy perineural neoplastic invasion and biopsy DNA ploidy determination. Biopsy Gleason score > or =7 was predictive of a pT3a stage (p=0.03). Statistically higher intensity of ET-1 PCa expression was observed in biopsies and specimens in pT3a group than in pT2 group (p<0.001 and p=0.01). In multivariate analysis, biopsy ET-1 PCa expression was an independent risk factor of pT3a stage with specificity 79 %, sensibility 69 %, predictive positive value 77 % and negative positive value 72 %. Combined with initial PSA > or =7, values were respectively 100 %, 76.9 %, 100 % and 57.1 %. CONCLUSION Endothelin-1 (ET-1) prostate cancer biopsy expression in our study was an independent prognostic factor of extracapsular stage (pT3a). Further studies will assess the relevance of ET-1 expression study in clinically localised PCa for active surveillance, curative treatment or targeted adjuvant therapy management.

Abstract
Transient coaxial helicity injection (CHI) started discharges in the National Spherical Torus Experiment (NSTX) have attained peak currents up to 300 kA and when coupled to induction, it has produced up to 200 kA additional current over inductive-only operation. CHI in NSTX has shown to be energetically quite efficient, producing a plasma current of about 10 A/J of capacitor bank energy. In addition, for the first time, the CHI-produced toroidal current that couples to induction continues to increase with the energy supplied by the CHI power supply at otherwise similar values of the injector flux, indicating the potential for substantial current generation capability by CHI in NSTX and in future toroidal devices.

Abstract
e11604 Background: Several authors reported sentinel lymph node biopsy after neoadjuvant chemotherapy. Nevertheless, the ideal time of sentinel lymph node biopsy is still a matter of debate. Methods: We evaluated the feasibility and the accuracy of sentinel lymph node biopsy before neoadjuvant chemotherapy using a combined procedure (blue dye and radio-labelled detection) in a homogeneous cohort study with clinically axillary node-negative breast cancer. Study candidates were patients referred to the Institut Paoli-Calmettes Cancer Center (Marseille, France) for the treatment of invasive breast cancer. Patients were included in the study if they had tumor more than 3 cm in diameter without palpable axillary lymph node for which a neoadjuvant chemotherapy was indicated in order to enhance the likelihood of breast conservation. An axillary lymph node dissection was performed after completion of neoadjuvant chemotherapy. Results: From September 2005 to September 2007, thirty-one women with T2 or T3 invasive breast cancer without palpable axillary lymph node underwent sentinel lymph node biopsy before neoadjuvant chemotherapy and an axillary lymph node dissection after neoadjuvant chemotherapy. Among the 20 women who had metastatic sentinel lymph node biopsy (65%), 4 (20%) had additional metastatic node on axillary lymph node dissection. By contrast, all the 11 women who had no metastatic sentinel lymph node biopsy had no involved nodes in the axillary lymph node dissection. The sentinel lymph node biopsy identification rate before neoadjuvant chemotherapy was 100% with any false negative. Conclusions: Sentinel lymph node biopsy before neoadjuvant chemotherapy is a feasible and an accurate diagnostic tool to predict the pre-therapeutic axilla status. These findings suggest that axillary lymph node dissection may be avoided in patients with a negative sentinel lymph node biopsy performed before neoadjuvant chemotherapy. No significant financial relationships to disclose.

Abstract
OBJECTIVES To compare the morbidity and functional results after laparoscopic radical prostatectomy with and without previous transurethral resection of the prostate (TURP). METHODS From May 1998 to January 2005, 640 patients underwent laparoscopic radical prostatectomy, of whom 46 (7.2%) had previously undergone TURP. The perioperative and postoperative data were compared between group 1 (with previous TURP) and group 2 (without previous TURP). The functional results were assessed by self-administered questionnaires at 12 and 24 months after surgery. RESULTS In group 1, the operative time, hospital stay, and bladder catheterization duration was increased by 31 minutes, 1.9 days, and 2.9 days, respectively. The positive margin rate was not significantly different statistically between the two groups (P = .62). The 5-year actuarial freedom from biochemical recurrence rate was similar between the two groups (P = .86). Surgical complications occurred in 15.2% of group 1 and 5.7% of group 2 (P = .02). The risk of anastomotic stricture was 6.5% and 1.2% in groups 1 and 2, respectively (P = .02). Two years after surgery, the continence rate was 86.9% in group 1 and 95.8% in group 2 (P = .77), and the potency rate was 63.8% and 70.9%, respectively, after bilateral neurovascular bundle preservation (P = .61). However, neurovascular bundle preservation was performed after previous TURP in only 56.5% of group 1 vs 78.9% in group 2 (P = .02). The median follow-up was 50.8 months (range 30-107). CONCLUSIONS Laparoscopic radical prostatectomy can be performed after TURP without compromising the oncologic results. However, patients should be informed that the procedure is associated with worse intraoperative and postoperative outcomes. Although the urinary continence rate was not hampered by previous TURP, neurovascular bundle preservation is technically more difficult and compromises postoperative erectile function.

Abstract
OBJECTIVE To analyse the levels of interleukin-6 (IL-6) in the synovial fluids and sera of patients with osteoarthritis (OA) and to identify the IL-6-secreting cells. METHODS Serum, synovial fluid, synovial tissue, and articular cartilage samples were collected from 49 OA patients with end-stage knee or hip OA who underwent joint replacement surgery. Serum and synovial fluid levels of IL-6 were measured by enzyme-linked immunosorbent assay (ELISA) and IL-6-secreting cells were identified by immunohistochemistry. RESULTS Eight out of 49 patients (16%) exhibited elevated IL-6 levels in the synovial fluids, averaging at 2022+/-526 pg/mL, while the levels in the rest of the patients averaged at 132+/-19 pg/mL. The sera levels of all patients were comparable in the 10 pg/mL range. Immunohistochemical analyses revealed plasma cells in the synovial lining of the high producers as the source of IL-6. CONCLUSIONS Synovial fluid IL-6 levels may help to classify OA patients and may point to a subgroup with a particular impact from their immune system.

Abstract
OBJECTIVES Multicentre practice evaluation in the field of penile prostheses based on the Club des Implanteurs de Prosthèses Péniennes (CIPP) database. METHOD 282 penile prostheses, including 276 inflatable prostheses (97.8%), were implanted in 254 patients between 1996 and 2005 in three centres (1 public and 2 private). Preoperative data (patient's age, aetiology and duration of erectile dysfunction, preliminary treatments) and intraoperative data (type of implant used, surgical approach) were recorded. Postoperative complications were studied and postoperative erectile function was evaluated by a self-administered questionnaire (IIEF). The mean follow-up was 27.7 months. RESULTS Penile prostheses were implanted after an average of 39.2 months of erectile dysfunction in patients with a mean age of 58.6 years. The main aetiologies were arterial disease (35.3%), diabetes (22.8%) and radical prostatectomy (16.5%). The postoperative sepsis rate was 2.2% and the mechanical dysfunction rate was 7.5% at the beginning of the operators' experience. The rate of other complications requiring repeat surgery (erosion, migration, self-inflation) was 1.8% at the beginning of the operators' experience. The septic risk was increased (7.6%) in the presence of diabetes (p = 0.01). The postoperative overall satisfaction was 86.7% and the IIEF score increased from 20.5 +/- 11.8 preoperatively to 68.9 +/- 5.4 postoperatively. CONCLUSION Penile prostheses achieve a high postoperative satisfaction score with a low complication rate. However, they are only indicated after failure of less invasive treatments and must be implanted by experienced operators. These results are comparable to those of large international single-centre series.

Abstract
A method of coaxial helicity injection has successfully produced a closed flux current without the use of the central solenoid in the NSTX device, on a size scale closer to a spherical torus reactor, for a proof-of-principle demonstration of this concept. For the first time, a remarkable 60 times current multiplication factor was achieved. Grad-Shafranov plasma equilibrium reconstructions are used to verify the existence of closed flux current. In some discharges the generated current persists for a surprisingly long time approximately 400 ms.

Abstract
INTRODUCTION Metalloproteinases (MMPs) promote cell migration and tumour invasion by degradation of the extracellular matrix. Activators and inhibitors (such as membrane type 1-matrix metalloproteinase or MT1-MMP and tissue inhibitor metalloproteinase 2 or TIMP-2) regulate metalloproteinase activity. The objective of this study was to determine the prognostic value of stromal immunolabelling with MMP-2, MT1-MMP and TIMP-2 in clinically localized prostate cancer. MATERIAL AND METHODS The immunohistochemical study was performed on 30 radical prostatectomy specimens. The results were compared to preoperative PSA, Gleason score, pT stage and biochemical recurrence with a minimum follow-up of 5 years. RESULTS Stromal immunolabelling with MMP-2 is correlated with stage pT3 (p=0.0022, OR=17.5). No correlation was observed with the other histoprognostic parameters. No statistical link was established with MT1-MMP and TIMP-2. CONCLUSION Stromal immunolabelling with MMP-2 is a histoprognostic marker of capsular effraction in prostatic adenocarcinoma. When performed on prostatic biopsies, it can predict the pT3 stage, allowing adaptation of the initial treatment in some patients.

Abstract
A series of time-resolved IR-IR double-resonance experiments have been conducted where methane molecules are excited into a selected rovibrational level of the 2nu3(F2) vibrational substate of the tetradecad and where the time evolution of the population of the various energy levels is probed by a tunable continuous wave laser. The rotational relaxation and vibrational energy transfer processes occurring in methane upon inelastic CH4-H2 and CH4-He collisions have been investigated by this technique at room temperature and at 193 K. By probing transitions in which either the lower or the upper level is the laser-excited level, rotational depopulation rates in the 2nu3(F2) substate were measured. The rate constants for CH4-H2 collisions were found to be 17.7 +/- 2.0 and 18.9 +/- 2.0 micros(-1) Torr(-1) at 296 and 193 K, respectively, and for CH(4)-He collisions they are 12.1 +/- 1.5 and 16.0 +/- 2.0 micros(-1) Torr(-1) at the same temperatures. The vibrational relaxation was investigated by probing other stretching transitions such as 2nu3(F2) - nu3, nu3 + 2nu4 - 2nu4, and nu3 + nu4 - nu4. A kinetic model, taking into account the main collisional processes connecting energy levels up to 6000 cm(-1), that has been developed to describe the various relaxation pathways allowed us to calculate the temporal evolution of populations in these levels and to simulate double-resonance signals. The different rate coefficients of the vibrational relaxation processes involved in these mixtures were determined by fitting simulated signals to the observed signals corresponding to assigned transitions. For vibration to translation energy transfer processes, hydrogen is a much more efficient collision partner than helium, nitrogen, or methane itself at 193 K as well as at room temperature.
