Orthotopic Mouse Models of Urothelial Cancer
2017
Orthotopic mouse models of urothelial cancer are essential for testing novel therapies and molecular manipulations of cell lines in vivo. These models are either established by orthotopic inoculation of human (xenograft models) or murine tumor cells (syngeneic models) in immunocompromised or immune competent mice. Current techniques rely on inoculation by intravesical instillation or direct injection into the bladder wall. Alternative models include the induction of murine bladder tumors by chemical carcinogens (BBN) or genetic engineering (GEM).
A simple method to treat post-kydney transplantation lymphocele
2011
OBJECTIVE: To describe our experience with ultrasonic-guided instillation of povidone-iodine to treat post-kidney transplantation lymphocele. Patients and methods. We studied the safety and efficacy of this procedure for treatment of lymphocele in 6 male kidney transplanted recipients in which we assisted a progressive increase of creatinine and urinary proteins levels and color-Doppler ultrasonography demonstrated an increase (25,4%) of index of resistence (IR) Using eco-colorDoppler, the related-graft lymphocele location and the distance to the anterior abdominal wall were determined; then, a radiopaque double-lumen catheter was used to instillate 5% povidone-iodine 10 ml. Results. Percut…
Does the Compliance to Intravesical BCG Differ between Common Clinical Practice and International Multicentric Trials?
2015
<b><i>Introduction:</i></b> The aim of this study was to analyze the reasons for intravesical BCG interruption in clinical practice. BCG for at least one year is advocated as the best regimen to treat high-risk non-muscle invasive bladder cancer (NMIBC). However, almost 50% of patients don't complete it. Toxicity accounts for 10% of dropouts in international trials. <b><i>Materials and Methods:</i></b> Patients with T1HG NMIBC undergoing 1-year BCG were enrolled in this study. BCG was administered for one year. Toxicity and causes of treatment interruption were recorded. <b><i>Results:</i></b> A total of 411 patients we…
The clinical value of PSA increase during intravesical adjuvant therapy for nonmuscle-invasive bladder cancer.
2016
Introduction Prostatic Specific Antigen (PSA), Bacillus Calmette-Guerin (BCG) increase after intravesical BCG has been reported. The need of prostate biopsy in these patients is object of debate. The aim of our study was to evaluate the effect of intravesical therapy on PSA after transurethral resection (TUR) of nonmuscle-invasive bladder cancer (NMIBC). Materials and methods Patients undergoing intravesical chemotherapy or immunotherapy for NMIBC were entered. PSA was measured before TUR, before the first and after the sixth instillation, 30 and 90 days after the last instillation. Patients with PSA ≥4 ng/ml or palpable prostate nodule were excluded. Results Out of 130 patients, 105 were e…
Is intravesical instillation of hyaluronic acid and chondroitin sulfate useful in preventing recurrent bacterial cystitis? A multicenter case control…
2015
Abstract Objective Urinary tract infections (UTIs) are common in the female population and, over a lifetime, about half of women have at least one episode of UTI requiring antibiotic therapy. The aim of the current study was to compare two different strategies for preventing recurrent bacterial cystitis: intravesical instillation of hyaluronic acid (HA) plus chondroitin sulfate (CS), and antibiotic prophylaxis with sulfamethoxazole plus trimethoprim. Materials and methods This was a retrospective review of two different cohorts of women affected by recurrent bacterial cystitis. Cases (experimental group) were women who received intravesical instillations of a sterile solution of high concen…
Adriamycin and Daunomycin in the Treatment of Vesical and Prostatic Neoplasias. Preliminary Results
1972
Our preHrninary experience with adriamycin in tumors of the bladder and prostate is of 25 treatments performed in 21 patients. The discrepancy between the numbers of patients and treatments is due to the fact that some patients were again submitted to various therapeutic cycles upon subsequent admissions. The treatments administered to the same patient at different times are considered individually, with regard either to a different schedule and way of administration of the drug, or to the interposition of other therapeutic means in the intervals between treatments. In addition, 13 patients were treated with daunomycin, as shown in Table 1.
Efficacy of Periportal Infiltration and Intraperitoneal Instillation of Ropivacaine After Laparoscopic Surgery in Children
2009
Postoperative pain is less intense after laparoscopic than after open surgery. However, minimally invasive surgery is not a a pain-free procedure. Many trials have been done in adults using intraperitoneal and/or incisional local anesthetic, but similar studies have not yet been reported in the literature in children. Aim: The aim of this study was to evaluate the analgesic effect of periportal infiltration and intraperitoneal instillation of ropivacaine in children undergoing laparoscopic surgery. Materials and Methods: Thirty patients who underwent laparoscopic surgery were randomly allocated to one of three groups. Group A (n 10) received local infiltration of port sites with 10 mL of ro…
Validation of a modified model of TNBS-induced colitis in rats. How to induce a chemical colitis in rats
2014
Background: there are no standard practice in the induction of colitis by 2,4,6-trinitrobenzene sulfonic (TNBS) acid. Usually, the repeated administration of TNBS is preferred, because it will result in a local Th1 response that has the characteristics of Crohn's disease. material and Methods: A total of 30 rats were randomized into two groups, consisting of a saline control group of ten rats and a TNBS groups of 20 rats. After the animals were anesthesized, 0,5 ml of either 0,9 % saline 8controls) or TNBS 50 mg/Kg dissolved in 50% ethanol were instilled into the colon through a rubber catheter. The experiment was repeated weekly for four weeks, then, the rats were killed at day 40, and the…
A prospective observational study on oral administration of Ellagic Acid and Annona Muricata in patients affected by non-muscle invasive bladder canc…
2021
Introduction: BCG and MMC shortage and Covid-19 pandemic, more recently, limit accessibility to maintenance regimen in intravesical prophylaxis against recurrence of non-muscle invasive bladder cancer (NMIBC). Ellagic acid (EA) and Annona muricata (AM) exert antitumor activity against different human tumours. An observational prospective study on the prophylactic effect of oral administration of EA+AM in patients avoiding maintenance regimen is presented. Materials and methods: Patients affected by NMIBC and not undergoing maintenance after a 6-week course of intravesical prophylaxis with MMC or BCG were entered. Tis and very high-risk tumours were excluded. After informed consent, the pati…
