Abstract
BACKGROUND A retrospective study was aimed to establish the eventual impact of narrow band imaging (NBI) cystos copy over the short term residual tumorsâ rate determined during the first follow-up endoscopic control in newly determined non-muscle invasive bladder cancer (NMIBC) cases. METHODS 68 patients were found with NMIBC by means of both white light cystoscopy (WLC) and NBI. A follow-up using both investigation modalities was performed at 3 months from the initial procedure in 67 cases (one was lost from follow-up). RESULTS concerning the short termer currences were retrospectively compared to those obtain ending a similar series of 67 patients previously diagnosed and treated by means of classical WLC and resection only. RESULTS The short term residual tumorsâ rate established during the first follow-up cystoscopy was lower in the study group initially benefiting from the NBI mode by comparison to the WLC control series (4.5% versus 11.9%). When drawing a parallel with the tumor map location outlined during the initial procedure, the most important differences were emphasized concerning other site recurrences (3%versus 8.95%). CONCLUSIONS NBI cystoscopy and resection displayed a substantially favorable influence over the short termoncologic outcome in newly diagnosed NMIBC cases when compared to the standard protocol. ABBREVIATIONS NBI â" narrow band imaging; NMIBC â"non-muscle invasive bladder cancer; WLC â" white light cystoscopy; TURBT â" transurethral resection of bladdertumors; CIS â" carcinoma in situ.

Abstract
OBJECTIVES A prospective study was performed aiming to evaluate the surgical efficacy, perioperative safety profile, diagnostic accuracy and medium term results of a multi-modal approach consisting in narrow band imaging (NBI) cystoscopy and bipolar plasma vaporization (BPV) when compared to the standard protocol represented by white light cystoscopy (WLC) and transurethral resection of bladder tumors (TURBT). MATERIALS & METHODS A total of 260 patients with apparently at least one bladder tumor over 3 cm were included in the trial. In the first group, 130 patients underwent conventional and NBI cystoscopy followed by BPV, while in a similar number of cases of the second arm, classical WLC and TURBT were applied. In all non-muscle invasive bladder tumors' (NMIBT) pathologically confirmed cases, standard monopolar Re-TUR was performed at 4-6 weeks after the initial intervention, followed by one year' BCG immunotherapy. The follow-up protocol included abdominal ultrasound, urinary cytology and WLC, performed every 3 months for a period of 2 years. RESULTS The obturator nerve stimulation, bladder wall perforation, mean hemoglobin level drop, postoperative bleeding, catheterization period and hospital stay were significantly reduced for the plasma vaporization technique by comparison to conventional resection. Concerning tumoral detection, the present data confirmed the NBI superiority when compared to standard WLC regardless of tumor stage (95.3% vs. 65.1% for CIS, 93.3% vs. 82.2% for pTa, 97.4% vs. 94% for pT1, 95% vs. 84.2% overall). During standard Re-TUR the overall (6.3% versus 17.4%) and primary site (3.6% versus 12.8%) residual tumors' rates were significantly lower for the NBI-BPV group. The 1 (7.2% versus 18.3%) and 2 (11.5% versus 25.8%) years' recurrence rates were substantially lower for the combined approach. CONCLUSIONS NBI cystoscopy significantly improved diagnostic accuracy, while bipolar technology showed a higher surgical efficiency, lower morbidity and faster postoperative recovery. The combined technique offered a reduced rate of residual tumors at Re-TUR, both globally as well as for orthotopic tumors. Substantially lower recurrence rates were found at 1 and 2 years among the NBI-BPV cases.

Abstract
OBJECTIVES A single centre, retrospective trial was performed trying to assess the impact of NBI cystoscopy in cases of non-muscle invasive bladder tumors (NMIBT) by comparison to the standard approach. Our goal was to determine the superiority of the new method in terms of detection rates and subsequent postoperative treatment changes. MATERIALS AND METHODS A total of 320 NMIBT suspected consecutive cases were enrolled in the study. The inclusion criteria were represented by hematuria, positive urinary cytology and/or ultrasound suspicion of bladder tumors. All patients underwent WLC and NBI cystoscopy. Standard transurethral resection of bladder tumors (TURBT) was performed for all lesions visible in WL and NBI guided resection for solely NBI observed tumors. RESULTS The overall NMIBT and CIS patients' detection rates were significantly improved for the NBI evaluation ((94.9% versus 88.1% and 95.7% versus 65.2%). Also, on a lesions' related basis, NBI cystoscopy emphasized a significantly superior diagnostic accuracy concerning the CIS, pTa and overall NMIBT formations ((95.2% versus 60.3%, 92.8% versus 83.9% and 94.1% versus 82%). Additional tumors were diagnosed by NBI in a significantly higher proportion of CIS, pTa, pT1 and NMIBT patients (56.6% versus 8.7%, 28% versus 10.3%, 30.3% versus 10.6% and 31.6% versus 9.4%). As a result of these supplementary findings, the postoperative treatment was significantly improved in a substantial proportion of cases (15.4% versus 5.1%). CONCLUSIONS NBI cystoscopy represents a valuable diagnostic alternative in NMIBT patients, with significant improvement of tumor visual accuracy as well as detection rates. This approach provided a substantial amelioration to the risk category stratification and subsequent bladder cancer therapeutic management.

Abstract
INTRODUCTION Secondary bladder neck sclerosis (BNS) represents a common late complication of prostate surgery, however so far insufficiently assessed in the available literature. More over, the previously attempted and analyzed therapeutic modalities failed to achieve acknowledgement as standard treatment for this particular pathology. METHODS The bipolar plasma vaporization (BPV) was introduced as a viable mean of removing the obstructing scar formation in a gradual fashion. Several "tips and tricks" were described as particularly useful in optimizing the plasma corona vaporization effect. The proper BPV technique is simple and safe while closely relying on certain surgical steps, the simultaneous vaporization and coagulation processes and a superior endoscopic vision. Recent technological advances created the premises for further improvements. RESULTS The plasma-button vaporization is characterized by a satisfactory surgical speed, remote intraoperative bleeding risks, high-quality endoscopic visibility as well as the achievement of a complete sclerotic tissue removal. Within a short learning curve, a superior final aspect of the prostatic fossa and bladder neck is obtained at the end of surgery. The continuous plasma vaporization mode provides additional technical advantages. The previously described drawbacks of transurethral incision or resection seem to have been overcome by the practical features of the plasma vaporization process. CONCLUSIONS The BPV technique outlines a promising modality of efficiently ablating the obstructing fibrous tissue in secondary BNS patients. The simplicity and safety of the bipolar vaporization approach, together with the thorough obstructing scar removal in a radical fashion, create the premises for a favorable long term BPV clinical outcome.

Abstract
INTRODUCTION The standard non-muscle invasive bladder cancer (NMIBC) endoscopic diagnosis suffers from the frequently unsatisfactory white light evaluation accuracy leading to residual lesions being left behind. Monopolar transurethral resection of bladder tumors (TURBT) is marked by a substantial morbidity rate requiring further amelioration. METHODS Small size tumors (under 1 cm) are feasible for "en bloc" resection. Bipolar TURBT was defined as being able to challenge the gold-standard status of monopolar resection due to the reduced complication rates. Plasma-button vaporization was introduced as a promising large bladder tumors' ablation modality. Narrow band imaging (NBI) cystoscopy became an increasingly popular method of enhancing tumor detection. RESULTS The "en bloc" resection of small size or thin pedicle tumors provides the conditions for avoiding tumoral tissue scattering. Bipolar resection is characterized by decreased perioperative bleeding risks and faster patient recovery. Plasma-button vaporization gained confirmation as an innovative approach, able to dispose large tumor bulks under complete control while minimizing the associated morbidity. NBI cystoscopy is a useful tool in identifying CIS lesions, small papillary tumors or extended margins of large tumor formations. As a cost-free technique, it may be extensively used both during the NMIBC initial diagnostic as well as during follow-up evaluation protocol. CONCLUSIONS Having in mind the various modalities of ameliorating the bladder cancer diagnostic and treatment, NMIBC management should be tailored in accordance with the particularities of each case.

Abstract
BACKGROUND Tumor cell invasion is the principal cause of treatment failure and death among patients with malignant gliomas. Connective tissue growth factor (CTGF) has been previously implicated in cancer metastasis and invasion in various tumors. We explored the mechanism of CTGF-mediated glioma cell infiltration and examined potential therapeutic targets. METHODS Highly infiltrative patient-derived glioma tumor-initiating or tumor stem cells (TIC/TSCs) were harvested and used to explore a CTGF-induced signal transduction pathway via luciferase reporter assays, chromatin immunoprecipitation (ChIP), real-time polymerase chain reaction, and immunoblotting. Treatment of TIC/TSCs with small-molecule inhibitors targeting integrin β1 (ITGB1) and the tyrosine kinase receptor type A (TrkA), and short hairpin RNAs targeting CTGF directly were used to reduce the levels of key protein components of CTGF-induced cancer infiltration. TIC/TSC infiltration was examined in real-time cell migration and invasion assays in vitro and by immunohistochemistry and in situ hybridization in TIC/TSC orthotopic xenograft mouse models (n = 30; six mice per group). All statistical tests were two-sided. RESULTS Treatment of TIC/TSCs with CTGF resulted in CTGF binding to ITGB1-TrkA receptor complexes and nuclear factor kappa B (NF-κB) transcriptional activation as measured by luciferase reporter assays (mean relative luciferase activity, untreated vs CTGF(200 ng/mL): 0.53 vs 1.87, difference = 1.34, 95% confidence interval [CI] = 0.69 to 2, P < .001). NF-κB activation resulted in binding of ZEB-1 to the E-cadherin promoter as demonstrated by ChIP analysis with subsequent E-cadherin suppression (fold increase in ZEB-1 binding to the E-cadherin promoter region: untreated + ZEB-1 antibody vs CTGF(200 ng/mL) + ZEB-1 antibody: 1.5 vs 6.4, difference = 4.9, 95% CI = 4.8 to 5.0, P < .001). Immunohistochemistry and in situ hybridization revealed that TrkA is selectively expressed in the most infiltrative glioma cells in situ and that the surrounding reactive astrocytes secrete CTGF. CONCLUSION A CTGF-rich microenvironment facilitates CTGF-ITGB1-TrkA complex activation in TIC/TSCs, thereby increasing the invasiveness of malignant gliomas.

Abstract
Despite similarities between tumor-initiating cells with stem-like properties (TICs) and normal neural stem cells, we hypothesized that there may be differences in their differentiation potentials. We now demonstrate that both bone morphogenetic protein (BMP)-mediated and ciliary neurotrophic factor (CNTF)-mediated Jak/STAT-dependent astroglial differentiation is impaired due to EZH2-dependent epigenetic silencing of BMP receptor 1B (BMPR1B) in a subset of glioblastoma TICs. Forced expression of BMPR1B either by transgene expression or demethylation of the promoter restores their differentiation capabilities and induces loss of their tumorigenicity. We propose that deregulation of the BMP developmental pathway in a subset of glioblastoma TICs contributes to their tumorigenicity both by desensitizing TICs to normal differentiation cues and by converting otherwise cytostatic signals to proproliferative signals.

Abstract
Karyotypic and cytogenetic characteristics of Vimba vimba and V. elongata were investigated using differential staining techniques (sequential C-banding, Ag- and CMA3-staining) and fluorescent in situ hybridization (FISH) with 28S rDNA probe. The diploid chromosome number in both species was 2n = 50 with 8 pairs of metacentrics, 14 pairs of submetacentrics to subtelocentrics and 3 pairs of subtelo- to acrocentrics. The largest chromosome pair of the complements was characteristically subtelo- to acrocentric. The nucleolar organizer regions (NORs) in both species were detected in the telomeres of a single, middle-sized subtelocentric chromosome pair, a pattern common in a number of other Leuciscinae. FISH with rDNA probe produced consistently positive hybridization signals detected in the same regions indicated by Ag-staining and CMA3-fluorescence. The distribution of C-positive heterochromatin was identical in both species, including a conspicuous size polymorphism of heterochromatic blocks in the largest metacentric and subtelo- to acrocentric chromosomal pairs. No heteromorphic sex chromosomes were detected. A single analyzed individual of V. melanops possessed the same karyotype and NOR phenotype as V. vimba and V. elongata. The apparent karyotype homogeneity and chromosomal characteristics of ribosomal DNA in all three species of the genus Vimba is consistent to that found in most other representatives of the European leuciscine cyprinid fishes.

Abstract
We present the case of a patient with an unusual, complex enteric fistula with multiple tracts and associated abscesses. The fistula was a late complication of radiotherapy, administered three years earlier, after resection for carcinoma of the sigmoid colon. Most of the small bowel was involved in the radiation-induced disease. A wide resection was performed successfully. This report reviews current literature on intra-abdominal postradiotherapy injuries, particularly intestinal fistulae.

Abstract
The authors present their experience about spinal anesthesia with pethidine as the sole medication. 713 patients whose mean age was 56.5 years received 1 mg . kg-1 of pethidine in 50 p. 100 aqueous solution administered by subarachnoid route. Indications were surgical procedures involving upper and lower abdomen, perineum and lower limbs. The set up of anesthesia is quite similar to those obtained with local anesthetics. Sensitivity disappears during the first three minutes in the area below the puncture site and in the following two or three minutes areflexia and paralysis is noted. The duration of the motor and sensory block is 90 to 120 minutes. Recovery appears to be in a reverse order. Spinal anaesthesia with pethidine exhibit the following characteristics: --sensory and motor blockade with minimal adverse reactions giving good and very good results in more than 90 per cent of cases, when involving perineum and lower limbs; --the most frequent adverse effect is a syndrome including hypotension, bradycardia and hypoxemia, appearing 20 to 30 minutes after injection, reversal is easily obtained by administration of pressure drugs and artificial ventilation. Neither delayed respiratory depression nor neurologic damage were noted; --a long lasting post-operative analgesia. In conclusion, this work demonstrates that: --1 mg . kg-1 of pethidine administered by subdural route realize a complete spinal anesthesia including motor, sensory and sympathetic blockade allowing surgical procedures in good conditions of security; --increasing the dosage of pethidine over 1 mg . kg-1 is not wise in order to avoid the occurrence of adverse side effects such as hypotension, bradycardia and bradypnaea; --this technic is only indicated for surgery in perineum and lower limbs.
