Abstract
Abstract
Bladder cancer incidence is investigated in the department of Bouches-du-Rhône to provide answers to the population reporting an excess of cancer cases in industrial areas. The study aimed to describe the geographical variations of bladder cancer incidence among men and detect potential spatial clusters without point source specification.
Incident cases diagnosed between 2013 and 2016 were extracted from the departmental observatory of cancers REVELA13. Age-standardized incidence ratios (SIRs) were calculated for each commune and bayesian smoothed risk estimate based on the Besag, York and Mollie model were computed for incidence mapping. Morans’I, Potthoff-Whittinghill and Tango statistic tests were used to investigate global clustering and the spatial scan statistic of Kulldorf (SaTScan) was used to investigate local clustering. Analyses were adjusted on a French deprivation index, access to health-care services and population density.
During the study period, 1 735 cases of bladder cancers were diagnosed among men. The study found a spatial heterogeneity (p < 0.01) and aggregation (p < 0.01) but no spatial autocorrelation (p = 0.09). Bayesian smoothed SIRs were not related to the confounding factors studied. An over-incidence was observed in the communes located in the South East of the department including Marseille, the biggest city of the study area. SaTScan algorithms detected two significant high-risk clusters in the same area (RR = 1.50 and 1.38). Introduction of each confounding factors in spatial scan detection, changed slightly the shape of clusters and/or the value of the relative risk but not the location. None high-risk cluster was detected in the communes of the industrial area.
Spatial analysis provides a first answer to the population concerning an excess of risk of bladder cancer at commune level. However, more analysis should be led to identify etiological factors or common environmental exposure.
Key messages
Geographic disparities exist in bladder cancer incidence among men at a commune level in the department of Bouches-du-Rhône. Spatial analysis show excess of risk of bladder cancer in the south-east of the department including the urban area of Marseille.

Abstract
A prospective study was designed to evaluate the efficacy of radionuclide hysterosalpingoscintigraphy using 99mTc-labelled human serum albumin macroaggregates in 17 patients (34 tubes). In normal females the niacroaggregates migrate spontaneously through the female reproductive tract following application into the posterior vaginal fornix. They can be seen in the uterine fornix 20 min p. i. (range: 5-90 min) and as free pelvic activity 120 min p. i. (range 40-180 min). Free pelvic activity could also be demonstrated by culdocentesis. In infertile patients with failure of tubal patency images after 180 min offered no additional information. For the routine diagnosis camera images 5, 60 and 180 min p. i. are recommended. Using 5-10 MBq 99mTc the radiation exposure to the ovaries is about 1/9th of the exposure from a normal radiologic hysterosalpingogram. The reported data show results comparable with those of hysterosalpingography (HSG) in females with patent or with nonpermeable tubes, but in cases of high-pressure patency by HSG the results of scintigraphy are superior to those of HSG. Moreover, this method provides new insights into sperm motility under various physiological and pathological conditions.

Abstract
OBJECTIVE To describe the socio-demographical aspects, etiologies and psychosocial consequences of urogenital fistula patients (UGF) in Burkina Faso (BF). PATIENTS AND METHODS Descriptive study of a cohort of consecutive patients during a period of 18 months (December 1st 2010 to August 31st 2012) in three centers of treatment in BF. Each patient has had a standardized complete medical observation focused on sociodemographics, clinical finding, past medical history and etiologies of UGF. Some patients had an interview with a psychologist. RESULTS One hundred and seventy patients with mean age 35 years (minimum: 16, maximum: 70) were enrolled during the study period. The majority of patients were housewives (90.5%, n=152) and illiterates (92.9%, n=158). Among the patients, 62.4% (n=106) lived in rural zones. Obstetrical fistula was the most common cause of UGF (87.6%, n=149) in our study and prolonged labor occurred in 93.3% (n=139) of cases with 17.5% (n=26) who delivered at home. The majority of our cases were vesico-vaginal fistula (70.6%, n=120). Fifty-five patients (32.4%) were divorced after the fistula. The sensation of humiliation and sadness were noted at all the patients who had a psychological evaluation and 87.5% (n=14) of them have had suicidal ideas. CONCLUSION The UGF are frequent in Burkina Faso and obstetrical etiology is dominant. The physical and psychosocial repercussions are important for the women victims of this pathology. LEVEL OF EVIDENCE 4.

Abstract
Elevated smoking rates seen in schizophrenia populations may be an attempt to correct neuropathologies associated with deficient nicotinic acetylcholine receptors and/or dopaminergic systems using exogenous nicotine. However, nicotine's effects on cognitive processing and sensory gating have been shown to be baseline-dependent. Evidence of a restorative effect on sensory gating deficits by nicotine-like agonists has been demonstrated, however, its underlying mechanisms in the context of dopamine dysregulation are unclear. Catechol-O-methyltransferase (COMT), a key dopamine regulator in the brain, contains a co-dominant allele in which a valine-to-methionine substitution causes variations in enzymatic activity leading to reduced synaptic dopamine levels in the Val/Val genotype. Using a randomized, double-blind, placebo-controlled design with 57 non-smokers, this study examined the effects of COMT genotype on sensory gating and its modulation by nicotine in low vs. high suppressors. The results were consistent with the hypothesis that increased dopamine resulting from nicotine stimulation or Met allelic activity would benefit gating in low suppressors and impair gating in high suppressors, and that this gating improvement with nicotine would be more evident in Val carriers who were low suppressors, while the gating impairment would be more evident in Met carriers who were high suppressors. These findings reaffirm the importance of baseline-dependency and suggest a subtle relationship between COMT genotype and baseline-stratified levels of sensory gating, which may help to explain the variability of cognitive abilities in schizophrenia populations.

Abstract
Malignant melanoma is a disease with an unpredictable evolution. Detected in stage I and II has a great chance to cure, if it is correctly treated: excisional biopsy with safety margins in accordance with tumor thickness. Lymphoscintigraphy with sentinel node identification and biopsy became compulsory for staging malignant melanoma, the role of complete lymphadenectomy would be established by publishing the MSLTII data. The sentinel node is analysed using more and more sophisticated techniques (RT-PCR) in order to detect isolated tumoral cells, although their clinical significance is not known yet. Metastases occurrence is a dramatic phenomenon because chemotherapy, radiotherapy or biologic therapy have insignificant results. The only therapeutic modality which may increase survival in this situation is surgery for some carefully selected patients.

Abstract
Although schizophrenia has been considered primarily a disease of dopaminergic neurotransmission, the role of dopamine in auditory sensory gating deficits in this disorder and their amelioration by smoking/nicotine is unclear. Hypothesizing that individual differences in striatal dopamine levels may moderate auditory gating and its modulation by nicotine, this preliminary study used the mid-latency (P50) auditory event-related potential (ERP) to examine the single dose (6 mg) effects of nicotine (vs. placebo) gum on sensory gating in 24 healthy nonsmokers varying in the genetic expression of the dopamine transporter (DAT). Consistent with an inverted-U relationship between dopamine level and the drug effects, individuals carrying the 9R (lower gene expression) allele, which is related to greater striatal dopamine levels, tended to evidence increased baseline gating compared to 10R (higher gene expression) allele carriers and showed a reduction in gating with acute nicotine. The present results may help to understand the link between excessive smoking and sensory gating deficits in schizophrenia and to explain the potential functional implications of genetic disposition on nicotinic treatment in schizophrenia.

Abstract
BACKGROUND Patients with respiratory disease use many different expressions to describe the sensation they experience as breathlessness. Although previous analyses have identified multiple dimensions of breathlessness, there is little agreement about their number and nature. This study has applied a novel approach, principal component analysis (PCA), to understanding descriptions of breathlessness in health and disease and extracting representative components. METHODS 202 patients (asthma n = 60, chronic obstructive pulmonary disease n = 65, interstitial lung disease n = 41, idiopathic hyperventilation n = 36) and 30 healthy volunteers were studied. All subjects performed spirometry and gave binary responses to 45 descriptions recalling their experience of breathlessness at the end of exercise; patients repeated this for resting breathlessness. PCA identified response patterns in the questionnaire data and extracted discriminatory components. Component scores were calculated for each individual using the regression method. RESULTS PCA identified six distinct components of breathlessness on exercise, explaining 62.8% of the variance: (1) air hunger, (2) affective, (3) nociceptive, (4) regulation, (5) attention and (6) miscellaneous qualities. Rest components explaining 63.1% of variance were (1) affective, (2) air hunger, (3) nociceptive, (4) wheeze, (5) regulation and (6) miscellaneous. Components identified on exercise differed significantly between disease groups and controls and were related to percentage predicted forced vital capacity. CONCLUSION This analysis suggests that air hunger is the dominant sensation during exercise, while affective distress characterises resting breathlessness in patients with a range of respiratory disorders including idiopathic hyperventilation where lung mechanics are normal. This suggests that common mechanisms operate in qualitative aspects of breathlessness.

Abstract
Access to comprehensive guidelines on the management of chronic obstructive pulmonary disease (COPD) is now available, and several treatment goals of therapy have been identified from these guidelines, which have since been studied in clinical trials. Drug therapy is a key component of an individual patient's management plan, particularly in more severe disease. During the past few years, a number of new drug treatments have become available, although these are not always appropriately prescribed; this is particularly the case for oxygen. For patients with a history of exacerbations, there is good evidence for the use of inhaled long-acting anticholinergic agents or combined inhaled steroids and long-acting beta-agonists. Evidence for prophylactic antibiotics and antioxidant agents is lacking. Nutritional and calorie supplementation have not been shown to improve exercise capacity. Statins may improve outcomes in COPD, but prospective trials are needed to confirm this. The evidence for the use of long-term oxygen therapy in hypoxaemic patients is robust. Ambulatory oxygen improves exercise capacity, but whether it is used appropriately is in doubt. Overall, short burst oxygen therapy does not offer a benefit and therefore cannot be recommended.

Abstract
The sentinel ganglion concept originates in the assumption according to which the primary tumor drains into a specific lymph node area and then runs through the lymphatic nodes in an orderly, sequential mode. When neoplastic dissemination along the lymphatic pathway occurs, there is an initial invasion of a specific lymph node (rarely more than one) located on the drainage route. That first lymph node has been identified as the sentinel node, which mirrors the regional lymph node status. In order to establish the indication for lymphadenectomy and avoid the situations in which such a surgical procedure would be of no use (N-), the only correct method consists in the identification and biopsy of the sentinel node which can be performed using vital staining (blue dye), radioactive tracers or both. The technique of sentinel lymph node identification and biopsy by means of radioactive tracing includes: -pre-surgical lymphoscintigraphy, -identification of the sentinel lymph node and its excisional biopsy, -intra-operative histopathological examination, paraffin embedded sections and immunohistochemical stains of the sentinel lymph node. The paper presents the refinement of the technique and the validation of the method for identification and biopsy of the sentinel lymph node in breast cancer with the intra-operative use of NEOPROBE 2000 gamma probe at the "Prof. Dr. Alexandru Trestioreanu" Oncological Institute in Bucharest. It is a prospective study which enrolled 93 patients with breast cancer between September 2003-December 2005, who underwent sentinel node biopsy. Complete axillary dissection (back-up lymphadenectomy) was performed in all cases. By comparing the pathological results of the frozen section of the sentinel node, with the paraffin embedded and immunohistochemical ones of the remaining axillary nodes, we present the following results: sensibility 97,15% (34/35), specificity 100% (93/93), positive predictive value 100% (34/34), negative predictive value 98,3% (58/59).

Abstract
18579 Background: There is evidence that daily intrarectal amifostine can protect rectal mucosa during prostate cancer treatment. Instruments more sensitive than the RTOG score may discriminate small but clinically important reductions in proctitis, however these tools need further evaluation. This study used both the RTOG GI toxicity score and expanded prostate cancer index composite (EPIC), a patient-administered quality of life instrument, to evaluate toxicity. Methods: In this pilot study, patients with localized prostate cancer were given daily amifostine (MedImmune, INC., Gaithersburg, MD) which was placed per rectum 30–45 min before 3D conformal radiation (66–76 Gy in 2 Gy fractions to a volume based on PSA, Gleason score and clinical stage). The first 18 patients enrolled received 1gram of amifostine and the next 12 patients were given 2 grams. Toxicity was assessed at baseline, 5, and 7 weeks during treatment and 3, 6, 12, 18, and 24 months after radiation and amifostine treatment. RTOG grading, an EPIC score and proctoscopic examination were done. The EPIC questionaire is a validated instrument that consists of 50 quality of life questions related to urinary, bowel, sexual and hormonal domains. Two subsets of the bowel domain were used: “bowel function” (BF) targets symptom severity and “bowel bother,” (BB) assesses quality of life subscales. Results: Previously reported results demonstrate a clear trend towards protection from rectal toxicity using 2 gm as compared to a 1 gm amifostine dose. Here, we report that the EPIC-BF and EPIC-BB scores are both highly correlated with the RTOG toxicity score with a pearsons coefficient of 0.98 and 0.97 respectively at a median follow up of 24 mos. There was no significant change in the RTOG GI toxicity score over the course of treatment for either amifostine dose group. There was a statistically significant decrease in EPIC-BF score at 7 weeks (p = 0.04) and the EPIC-BB score showed a trend toward improvement (p = 0.07) at the same time point. The EPIC scores at all other time points were not statistically different from baseline. Conclusions: The EPIC score may be a more sensitive measure to detect acute toxicity associated with prostate cancer treatment but needs further investigation in the acute setting. No significant financial relationships to disclose.

Abstract
12503 Background: Despite new treatments, lung cancer remains the leading cause of cancer death. We examined the safety and activity of antitumor vaccination using genetically altered human non-small cell lung cancer cells (HAL; HyperAcute Lung Cancer Vaccine) engineered to express xenotransplantation antigens through retroviral transfer of the murine αGT gene in patients (Pts.) with NSCLC. Methods: A single institution Phase I trial. Eligibility: Stage IV, recurrent or progressive NSCLC, Age ≥18, ECOG PS ≤2, prior chemotherapies ≤2, AGC ≥1,500/μL, Plts. ≥100,000/μL, adequate hepatic/renal function and informed consent. Cohorts of Pts. received intrademal injections of 3 × 106, 10 × 106, 30 × 106, or 100 × 106 HAL vaccine cells every 4-weeks × 4, or 500 × 106 HAL cells followed by 300 × 106 HAL cells every 2-weeks × 7. Toxicity was assessed using CTCv3.0 and response by RECIST criteria. Immunological responses included anti-αGal antibody titers, interferon-γ ELISPOT and vaccine site skin biopsies. Results: Seventeen Pts., 9 men and 8 women, median age 57 years (range, 34–85), median number of prior chemotherapies 1 (range, 1–2) were vaccinated. There were no Grade 3/4 adverse events attributable to the study vaccine. Adverse events (≤grade 2) attributable to vaccination include injection site urticaria, pain/discomfort, local skin reaction, fatigue, herpes zoster, arthralgias/myalgias and hypertension. Six Pts. had stable disease ≥16 weeks duration (range, 16–85+ weeks), 9 Pts. progressed and 2 Pts. were not evaluable for response. Skin biopsies 48-hrs after vaccination demonstrated vaccine cells in the dermis with acute infiltration of lymphocytes, granulocytes and eosinophils. Serum anti-αGal titers increased 10–14 fold with vaccination. Conclusions: Xenogeneic antitumor vaccination with genetically altered allogeneic human lung cancer cells expressing αGT is safe and feasible. A phase II trial is planned. No significant financial relationships to disclose.

Abstract
Overexpression of a membrane glycoprotein (P170) represents the most common multidrug resistance (MDR) mechanism in cancer therapy. Specific autoantibodies to extracellular loops 1, 2 and 4 of murine P170 are elicited in mice using palmitoylated synthetic peptides reconstituted in liposomes with or without Lipid A and resuspended in alum. IgM antibodies are detected 14 days following the first injection and IgG1 become predominant after the third challenge. Animals do not show any autoimmunity symptoms or induced toxicity up to 18 months after the immunization. Previous immunizations of mice using liposomes with mdr1 peptides efficiently improve chemotherapy with doxorubicin and vinblastine against P388 R cells with a 77% increase of survival half time in the immunized group. Sera from immunized mice are also effective in reducing cellular resistance to vinblastine and doxorubicin in vitro. Taken together these data suggest that this immunization approach might have potential clinical applications.

Abstract
BACKGROUND Oesophageal squamous cell carcinoma (OSCC) is a common cancer worldwide and has a very high mortality rate. Squamous dysplasia is the precursor lesion for OSCC and it can be seen during routine endoscopy with Lugol's iodine staining. We aimed to examine the risk factors for squamous dysplasia and determine if a risk model could be constructed which would be useful in selecting apparently healthy subjects for endoscopic screening in a high risk population in Linzhou, People's Republic of China. SUBJECTS AND METHODS In this cross sectional study, 724 adult volunteers aged 40-65 years were enrolled. All subjects completed a questionnaire regarding potential environmental exposures, received physical and dental examinations, and underwent upper endoscopy with Lugol's iodine staining and biopsy. Subjects were categorised as having or not having histologically proven squamous dysplasia/early cancer. Risk factors for dysplasia were examined using univariate and multivariate logistic regression. The utility of the final multivariate model as a screening tool was assessed using a receiver operating characteristics curve. RESULTS We found that 230 of 720 subjects (32%) with complete data had prevalent squamous dysplasia. In the final multivariate model, more household members (odds ratio (OR) 1.12/member (95% confidence interval (CI) 0.99, 1.25)), a family history of cancer (OR 1.57 (95% CI 1.13-2.18)), higher systolic blood pressure OR 1.11/10 mm Hg (95% CI 1.03-1.19)), heating the home without a chimney (OR 2.22 (95% CI 1.27-3.86)), and having lost more but not all of your teeth (OR 1.91 for 12-31 teeth lost (95% CI 1.17-3.15)) were associated with higher odds of having dysplasia. Higher household income (OR 0.96/100 RMB (95% CI 0.91-1.00)) was associated with a lower odds of having dysplasia. Although we found several statistically significant associations, the final model had little ability to accurately predict dysplasia status, with maximum simultaneous sensitivity and specificity values of 57% and 54%, respectively. CONCLUSIONS We found that risk factors for dysplasia were similar to those previously identified as risk factors for OSCC in this population. The final model did a poor job of identifying subjects who had squamous dysplasia. Other methods will need to be developed to triage individuals to endoscopy in this high risk population.

Animals did not show any auto-immune symptoms or induced toxicity up to 18 months after the immunisation. Previous immunisations of mice using liposomes with MDR1 peptides increases the efficacy of chemotherapy treatments with doxorubicin and vinblastine against P388 R cells with increase of 77% in the survival half time in the immunised group. Sera from the immunised mice were also effective in reducing cellular resistance to vinblastine and doxorubicin in vitro. Taken together, these data suggest that this immunisation approach might have potential clinical applications.

Abstract
BACKGROUND The Polyp Prevention Trial (PPT) was a multicenter randomized clinical trial designed to determine the effects of a high-fiber (4.30 g/MJ), high-fruit-and-vegetable (0.84 servings/MJ), low-fat (20% of energy from fat) diet on the recurrence of adenomatous polyps in the large bowel. OBJECTIVE Our goal was to determine whether the PPT intervention plan could effect change in 3 dietary goals and to examine the intervention's effect on the intake of other food groups and nutrients. DESIGN Participants with large-bowel adenomatous polyps diagnosed in the past 6 mo were randomly assigned to either the intervention (n = 1037) or the control (n = 1042) group and remained in the trial for 4 y. Three dietary assessment instruments were used to measure dietary change: food-frequency questionnaires (in 100% of the sample), 4-d food records (in a 20% random cohort), and 24-h dietary recalls (in a 10% random sample). RESULTS Intervention participants made and sustained significant changes in all PPT goals as measured by the dietary assessment instruments; the control participants' intakes remained essentially the same throughout the trial. The absolute differences between the intervention and control groups over the 4-y period were 9.7% of energy from fat (95% CI: 9.0%, 10.3%), 1.65 g dietary fiber/MJ (95% CI: 1.53, 1.74), and 0.27 servings of fruit and vegetables/MJ (95% CI: 0.25, 0.29). Intervention participants also reported significant changes in the intake of other nutrients and food groups. The intervention group also had significantly higher serum carotenoid concentrations and lower body weights than did the control group. CONCLUSION Motivated, free-living individuals, given appropriate support, can make and sustain major dietary changes over a 4-y period.

Abstract
For differences among materials to be easily detected, low variation in in vitro wear tests is desirable. The working hypothesis of this paper was that antagonists standardized for shape and size and according to materials would show mean values similar to those found in natural, non-standardized cusps, and that standardization would lead to a reduction in mean variation. First, the shapes and sizes of palatal cusps of non-erupted human upper third molars were measured. The cusp cupola was best described by the formula y = 0.001 x2 and was symmetrical around the axis of rotation. Up to 200 microm of the y-axis, this parabola corresponded best to a ball radius of 0.6 mm. Based on this information, standardized antagonists were fabricated from both human enamel and steatite. Wear in the occlusal contact area and the wear of opposing conventional ceramic and fine hybrid composite, respectively, were quantified in a computerized chewing simulator. As a control, natural human enamel cusps were used. Standardization of enamel cusps did not reduce the variation of the resulting wear compared with that of non-standardized enamel antagonists. Furthermore, standardization led to significantly different results both in the antagonists and in the opposing restorative materials. Thus, natural enamel antagonists are preferable for the simulation of wear in the occlusal contact area.

Abstract
This article reports our early experience using laparoscopic instruments and techniques when performing radical retropubic prostatectomy through an entirely extraperitoneal endoscopic approach. Two patients with localized adenocarcinoma of the prostate underwent endoscopic radical retropubic prostatectomy through an entirely extraperitoneal approach (EERRP). The procedure was evaluated for its efficacy in removing prostate and seminal vesicles and in effecting complete vesicourethral anastomosis. Operative time, blood loss, hospital stay, and pathology were also evaluated. Complete endoscopic removal of the prostate and seminal vesicles was achieved in both patients. Endoscopic reconstruction of the bladder neck with watertight anastamosis was successful in both. Operative time and estimated blood loss improved from 5 h and 45 min and 600 cc, respectively, in patient 1 to 4 h and 400 cc in patient 2. Hospital stay was 2.5 days for both. The early experience for EERRP is encouraging. Further evaluation to standardize technique and determine its efficacy and role in treating prostate cancer is in order.

Abstract
A dramatic growth has been seen in the number of organ procurement organizations, transplant programs, and new initiatives related to solving the organ shortage, as well as in the development of protocols dealing with the logistics of facilitating organ and tissue recovery. Extensive deliberation on critical issues related to the organ donor shortage is evident in professional meetings, publications, and educational endeavors. Little research has been conducted, however, regarding direct contact between donor families and recipients, a highly controversial subject in transplantation and procurement. Should there be contact between donor families and recipients? What format should such contacts take? Who should decide? These are questions that must be considered in the field. This article will explore an organ procurement organization's 5-year experience regarding direct contact between donor families and recipients.

Abstract
The Prevention of Events with Angiotensin-Converting Enzyme Inhibition (PEACE) trial is an 8,100 patient, randomized, double-blind, placebo-controlled trial designed to determine the usefulness of angiotensin-converting enzyme (ACE) inhibitors in treating coronary patients with preserved left ventricular ejection fraction. The hypothesis being tested in this trial is that patients with coronary disease and ejection fraction > or =40% who are treated with ACE inhibitors will experience a reduction in the incidence of cardiovascular death, nonfatal myocardial infarction, or a revascularization procedure compared with patients treated with conventional therapy. The design of the PEACE trial is described herein.

Abstract
Linker histones from grapevine were purified by electrophoretic methods (SDS-PAGE and electrotransfer onto a nitrocellulose sheet). Individual linker histones were recovered after nitrocellulose solubilization by acetone. The proteins precipitated after this treatment were used as antigen for subsequent immunizations of mice. Such purified immunogens were injected into mice with dimethyl sulfoxide, as the presence of nitrocellulose-protein complexes in the antigen pellets after the acetone treatment was suspected. The resulting antisera were specific to the injected antigens after only the first immunization and could be used as specific probes in immunohistological studies. Our approach seems more efficient (in using less antigen and obtaining a faster response) than the classical procedure recommended for histones in general (B. D. Stollar and M. Ward, 1970, J. Biol. Chem. 245, 1261-1266) and other methods that use free linker histone as immunogen.

Abstract
PURPOSE We evaluate the efficacy of high dose combination radiotherapy for the treatment of localized prostate cancer. MATERIALS AND METHODS A total of 212 patients with localized prostate cancer (T1-T3) were treated with transperineal radioactive seed implantation followed by 45 Gy. external beam radiation therapy. Patients with Gleason scores of 2-5 were treated with 125iodine at a minimum peripheral dose of 120 Gy., while 103palladium at a minimum peripheral dose of 90 Gy. was used for those with Gleason scores of 7-10. Patients with Gleason 6 diploid tumors were treated with 125iodine and those with aneuploid tumors were treated with 103palladium. Biochemical failure was defined as inability to achieve a prostate specific antigen nadir value of 0.5 ng./ml. or less. No patient was treated with androgen deprivation therapy. RESULTS The 212 patients have a minimum of 24 months of followup (mean 33 months). Prostate specific antigen 0.5 ng./ml. or less was reached by 72% of the patients (152 of 212) and positive biopsies were detected in 13.9% (20 of 144). Using life table survivorship analysis the probability of initial biochemical success at 5 years was 91% (95% confidence interval, 83 to 97). The probability of subsequent failure following an initial success was 11% (95% confidence interval, 6 to 20) at 24 months. The complications of combination therapy included proctitis in 21.4% (47 of 212 men), impotence in 38% (38 of 100), urinary retention in 1.5%, incontinence in 2.8%, rectoprostate fistula in 2.4%, rectal wall breakdown in 0.5% and urethral stricture in 0.5%. Six patients (2.8%) required colostomy and urinary diversion. CONCLUSIONS Short-term responses to high dose combination radiotherapy for localized prostate cancer are promising. The morbidity is acceptable. Further long-term followup is warranted to assess this treatment.

Abstract
PURPOSE We evaluated the efficacy of a totally extraperitoneal approach to endoscopic pelvic lymph node dissection. MATERIALS AND METHODS Extraperitoneal endoscopic pelvic lymphadenectomy was performed in 125 patients with clinically localized prostate cancer. All patients were candidates for brachytherapy, cryotherapy or radical perineal prostatectomy. The first 65 patients underwent lymphadenectomy regardless of local clinical stage, prostate specific antigen (PSA) or tumor grade. The last 60 patients met 2 of 3 selection criteria, consisting of clinical local stage T2b or greater, prostate specific antigen greater than 20 and Gleason score 7 or higher. Patients were evaluated for morbidity and mortality, nodal yield, operative time, conversion rate to transperitoneal laparoscopic or open lymphadenectomy and hospital stay. RESULTS Mean operative time was 104 minutes, mean length of stay was 2.1 days and mean nodal yield was 10.2. Of the patients 19.2% had positive nodes, and positive nodal yield increased to 32.9% when selection criteria were used. Of the cases 4% were converted to a transabdominal laparoscopic approach and 2.4% to open lymphadenectomy. Symptomatic lymphoceles required percutaneous drainage in 2.4% of the patients. One patient died of massive pulmonary embolism. CONCLUSIONS This study demonstrates that the extraperitoneal endoscopic pelvic lymph node dissection is an effective and relatively safe method of surgically staging prostate cancer. It compares favorably to other methods of surgical staging.

Abstract
OBJECTIVES We report our initial experience using laparoscopic instruments and techniques in the performance of radical retropubic prostatectomy (RRP) through an entirely extraperitoneal endoscopic (EE) approach. METHODS A 62-year-old man with a Gleason score of 7 and clinical stage T1c adenocarcinoma of the prostate underwent EERRP. The procedure was evaluated for achievement of removal of the prostate and seminal vesicles and for complete vesicourethral anastomosis. Operative time, blood loss, hospital stay, and pathologic findings were also evaluated. RESULTS Complete endoscopic removal of the prostate and seminal vesicles was achieved. Endoscopic reconstruction of the bladder neck with a watertight anastomosis was successful. Operative time was 5 hours and 45 minutes, with an estimated blood loss of 600 cc. Hospital stay was 2.5 days. Final pathologic evaluation was a Gleason score of 7 and Stage T2 disease with negative margins. CONCLUSIONS The initial experience for EERRP is encouraging. Further evaluation to refine the technique and determine its efficacy and role in treating prostate cancer is in order.

Abstract
The objective of this study was to determine whether extraperitoneal lymph node dissection for the staging of prostate cancer and extraperitoneal herniorrhaphy could be performed concomitantly with acceptable operative time and morbidity. Sixty patients underwent endoscopic extraperitoneal lymph node dissection (EEPLND) between 1991 and 1996. Eleven of these had 14 hernias repaired with polypropylene mesh. Endoscopic hernia repair added an average of 15 to 20 minutes to the EEPLND, resulting in an average operative time of 127 minutes (range 90 to 182 minutes). There was no difference in postoperative pain between patients undergoing combined operations and those undergoing EEPLND alone. The mean hospital stay after either procedure was 48 hours. There were no complications in the group undergoing herniorrhaphy. We conclude that extraperitoneal endoscopic hernia repair can be safely performed with EEPLND when necessary.

Abstract
OBJECTIVE To compare two contact and non-contact techniques using the VLAP system (visual laser ablation of the prostate). PATIENTS AND METHOD From January 1994 to April 1995, two groups of 50 patients were included in a randomized prospective study and were treated by the contact and non-contact laser technique, respectively. These patients presented with symptomatic BPH requiring transurethral electroresection. These patients were evaluated according to subjective (AUA score) and objective criteria (maximum flow rate, transrectal and suprapubic ultrasonography). ND:YAG laser energy was delivered by a Medilas 4100 source via a lateral beam fibre. Objective success criteria were an improvement of the AUA score by at least 50% and of the maximum flow rate by at least 50% with a difference of 4 mL/s. The failure criterion was the need to perform complementary electroresection during the first 6 postoperative months. RESULTS The mortality was 2% (cardiovascular causes), and the overall morbidity (first postoperative month) was 29%, with 21% of a vesical irritation syndrome, 6% of urinary tract infection and 2% of bladder clots. The global result at 12 months showed a statistically significant postoperative improvement of the subjective and objective parameters studied preoperatively (p = 0.0001). In the contact group, the AUA score, mean maximum flow rate and residual urine, which had preoperative values of 19.1, 9.1 mL/s and 141 mL, respectively, were equal to 2.3, 15.6 mL/s and 45 mL at 12 months. In the non-contact group, the same parameters, which had preoperative values of 17.8, 9.2 mL/s and 87 mL, respectively, were equal to 3.8, 13.3 mL/s and 47 mL at 12 months. The results, evaluated as a function of objective success criteria, showed a 12-month success rate of 68% for the contact method and 61% for the non-contact method. The mean hospital stay was 6 days and the mean duration of bladder catheterization was 5 days with the two techniques. During follow-up, 7% of patients required revision by electroresection, regardless of the technique used. CONCLUSION this study demonstrated identical results for the contact and non-contact techniques using the VLAP system.

Abstract
This study was designed to assess the efficiency of 2 kind of laser prostatectomy devices in the treatment of Benign Prostatic Hyperplasia: a non contact technique versus a contact technique versus a contact one. From January 1994 to September 1994, 100 patients were included in a randomized comparison of 2 laser prostatectomy devices with right angle firing laser fibers: a non contact technique with Urolase fiber (Bard) (50 patients) versus a contact technique with Fibertom fiber (Dornier) (50 patients). The Urolase fiber was used at 60 Watts power setting for 60 seconds and administered to each lobe at 2, 4, 8 and 10 o'clock positions. The Fibertom fiber was used by dragging or the so called "painting" technique at 3 and 6 months with 3 parameters: Madsen symptom scores, peak urinary flow rates and post-void residual urine volumes. Operative morbidity rate was 9%. No difference in morbidity between both fibers. No blood transfusion was required in any case. Statistical analysis of the aforementioned parameters shows a p-value of < 0.001 for all parameters. Comparing the 2 different fibers, there was no statistical difference in outcome for any of these parameters. From this study we conclude that the preliminary results achieved, using the Urolase and the Fibertom fiber, are equivocal and interesting. However, a long term follow-up is necessary to evaluate the definitive efficiency of laser prostatectomy and to determine the optimal procedure.

Abstract
This study examined the relationship between post-stroke lesion size and location and depressed mood by using data from the multicenter National Stroke Data Bank. For in patients with first-ever cerebral infarction, lesions were characterized by location and size from CT scans. Forty-seven (24%) of the 193 patients studied were depressed. In the complete sample, neither lesion size nor location was associated with depression. However, among patients with comparable small-sized lesions (n = 124), depression was more frequent among those with left hemisphere stroke than those with right hemisphere stroke (31% vs. 16%; P = 0.04). Among patients with larger lesions, brain edema was common and may have obscured lateralized findings. Different biogenic amine neurotransmitter responses to right and left hemisphere brain injury may underlie this mood asymmetry.

Abstract
We studied the effect of felbamate (FBM) monotherapy on seizure rate in patients with partial and secondarily generalized seizures undergoing presurgical monitoring at a single site. The study design was a double-blind placebo-controlled parallel monotherapy trial. Forty patients whose seizures had not been controlled by standard antiepileptic drugs (AEDs) were randomized. Seizure type was confirmed by video-EEG monitoring. All baseline AEDs were discontinued, and patients were drug-free for 5.3 +/- 2.4 days before randomization to FBM or placebo. After a 4-day titration, seizures were counted for 14 days. Patients receiving FBM had significantly lower seizure rates, whether all randomized patients, patients who survived titration, or study completers were compared. Eight of 19 placebo patients randomized to placebo, as compared with 13 of 21 receiving FBM, completed the 18-day study. Two FBM patients dropped out due to seizures, and 6 dropped out due to side effects, including anxiety, difficulty sleeping, abdominal discomfort, acute psychosis, and orobuccal dyskinesias. Ten placebo patients met the criteria for premature discontinuation owing to seizures, and 1 hd an episode of panic. There was no evidence of hepatic or hematologic toxicity. FBM reduces seizure frequency in patients with localization-related epilepsy.

Abstract
An improved method for the electrophoretic transfer of histones from sodium dodecyl sulfate (SDS) and acetic acid-urea-Triton X-100 (AUT) polyacrylamide gels onto nitrocellulose membranes is described. In the case of SDS-gels, it was not essential to equilibrate them before transfer while for the AUT-gels, an equilibration step is essential to prevent the interference of Triton X-100 with the binding of histones to nitrocellulose. Transfer efficiency was different for different histone classes. Two procedures were developed: (1) one suitable for qualitative studies, and (ii) another for quantitative transfer.

Abstract
OBJECTIVE To examine the time course of alterations in glucose metabolism in relation to the interval from the last seizure, focus laterality, seizure frequency, and seizure type. DESIGN Metabolic study with the use of positron emission tomography with fludeoxyglucose F 18. Blinded scan evaluation with use of a standard template. Multivariate regression analysis of positron emission tomographic data. SETTING National Institutes of Health Clinical Center, Bethesda, Md. PATIENTS Thirty-two adults with intractable partial epilepsy and lateralized seizure onset documented by video-electroencephalographic monitoring. MAIN OUTCOME MEASURE Normalized metabolic rate for glucose ipsilateral and contralateral to the epileptic focus. RESULTS The most dramatic changes occurred in inferior temporal regions; the midtemporal region was affected as well. Effects lasting 48 hours were found after both simple and complex partial seizures. The time course was different for the two types of seizures. The inferior temporal metabolic rate ipsilateral to the focus increased compared with the interictal rate during the 24-hour period following simple partial seizures; a nadir occurred in the second 24 hours. The rate then rose to an intermediate level after 48 hours. The relative to an intermediate level after 48 hours. The relative regional increase in ipsilateral metabolism following complex partial seizures persisted for 48 hours before falling. CONCLUSION The brain may take longer than 24 hours after a partial seizure to return to its baseline state.

Abstract
We studied 120 generalized tonic-clonic seizures (GTCSs) in 47 patients with video-EEG telemetry. GTCSs were preceded by antecedent seizures, including 13 simple partial, 70 complex partial, 17 simple partial leading to complex partial, seven tonic, seven clonic, and one typical absence. We divided GTCSs into the following phases: onset of generalization, pretonic clonic, tonic, tremulousness, and clonic. The mean GTCS duration was 62 seconds. There was a non-significant trend toward longer duration on reduced antiepileptic drug doses. Marked heterogeneity in GTCS phenomenology was present; only 27% of seizures included all five phases. Individual phase duration and clinical expression, including tonic and clonic phases, was highly variable. The clinical phenomena suggest that multiple cortical and subcortical routes of spread may exist. When GTCSs last longer than 2 minutes, intravenous antiepileptic drug treatment should be initiated.

Abstract
The insufflated extraperitoneal approach to endoscopic pelvic lymph node dissection has been described as an alternative method of staging carcinoma of the prostate. There are several potential pitfalls in performing this approach, including the use of endoscopic instrumentation, trocars, insufflation equipment, and general anesthesia. In order to overcome potential problems associated with this surgical approach, a totally gasless extraperitoneal approach has been developed. This technique uses standard surgical instruments, does not use carbon dioxide to maintain the operative space, and uses general anesthesia. This procedure is more cost effective, since it uses no special instrumentation except the laprolift and laprofan to maintain the extraperitoneal cavity during lymph node dissection.
