Validation of Fenoterol to Study β<sub>2</sub>-Adrenoceptor Function in the Rat Urinary Bladder

2021

Fenoterol is a β<sub>2</sub>-adrenoceptor (AR)-selective agonist that is commonly used to investigate relaxation responses mediated by β<sub>2</sub>-AR in smooth muscle preparations. Some data have questioned this because fenoterol had low potency in the rat urinary bladder when a muscarinic agonist was used as a pre-contraction agent and because some investigators proposed that fenoterol may act in part via β<sub>3</sub>-AR. We designed the present study to investigate whether fenoterol is a proper pharmacological tool to study β<sub>2</sub>-AR-mediated relaxation responses in the rat urinary bladder. Firstly, we have compared the effect of p…

Are morphology and composition of gallstones related? An x-ray diffraction study

1994

Abstract An x-ray diffractometric technique was used to study the crystalline composition of gallstones removed during surgery from 106 patients. Monohydrate cholesterol was found in the stones of 70 (66%) patients, either alone (33%) or in association with calcium salts (33%). The anhydrous form of cholesterol was found in the stones of 28 (26%) patients, either alone (10%) or in association with calcium salts (16%). These salts (vaterite, aragonite, and calcite) were found in 50% of cases in varying amounts (from 12% to 15% of the stone weight). Eight stones contained no cholesterol: 4 showed an amorphous pattern and 4 were composed of calcium carbonate salts. In 7 of 8 patients with bile…

Authors' response to Hermann et al. Minimum quality criteria are needed in the assessment and communication of unexpected drug safety findings of mar…

2012

Hermann et al. [1] suggest that minimum quality criteria are needed to communicate unexpected drug safety findings from randomized clinical trials and imply that our report on unexpected frequent hepatotoxicity in patients receiving flupirtine for the treatment of overactive bladder syndrome [2] does not meet such criteria. As the brief report format of our paper did not allow an extensive description of trial details, we welcome this opportunity to shed more light on the matter.

Environmental Risk Factors in Superficial Bladder Cancer

2004

As a preliminary approach to define the object of larger case-control studies, the distribution of potential risk factors coming from environmental pollution among patients affected by superficial bladder cancer (TCCB) has been analyzed. Material e Methods. The analysis included only patients affected by medium risk superficial TCCB. Forty Italian urological centres joined the study. Detailed information about age, sex, residency, employment, active and passive cigarette smoking, water resource, hair-dye use were centralized. All patients underwent TUR and early intravesical chemotherapy. The distribution of the above mentioned environmental factors was related to tumor characteristics suc…

Sludge and stones in gallbladder after pregnancy

1987

Summary The prevalence of sludge and stones in the gallbladder of 298 women in the immediate post-partum period was ultrasonographically assessed. We have investigated some risk factors for the development of sludge or stones in these patients and followed up most of these patients by ultrasonography to detect the presence of sludge and/or stones in the year following their discovery. We found sludge in 80 (26.2%) and gallstones in 16 (5.2%) of these patients. Age, obesity and months of oral contraceptive use were risk factors only for the presence of gallstones. After 1 year of follow-up only 2 out of 45 patients with sludge but 13 out of 15 patients with gallstones still had abnormal ultr…

Factors predicting continence recovery 1 month after radical prostatectomy: Results of a multicenter survey

2011

Objectives: To assess the factors associated with continence recovery 1month after radical prostatectomy (RP) and to identify the correlation between these factors. Methods: In total, 2408 men treated with RP for prostate cancer (PCa) were enrolled in the present multicenter prospective study. Clinical (age, body mass index) and urological (catheterization or transurethral resection of the prostate) records, quality of life (QOL) scores determined using various instruments (including the International Index of Erectile Function [IIEF] and University of California Los Angeles, Prostate Cancer Index [UCLA-PCI]), PCa characteristics (clinical stage [cT], prostate-specific antigen, biopsy Gleas…

Quality of life in women undergoing urinary diversion for bladder cancer: results of a multicenter study among long-term disease-free survivors

2012

Purpose: Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). Materials and methods: All consecutively treated female patients from t…

THE IMPACT OF NUMBER OF LYMPH NODE REMOVED IN THE DETECTION OF LYMPHNODE METASTASIS: A SENSITIVITY CURVE ANALYSIS.

2014

Scopo del lavoro To assess the correct number of lymph nodes (LNs) to removed at Radical Cystectomy (RC) to ensure an accurate lymph nodes metastasis (LNM) staging. Materiali e metodi Between 1995 and 2012, 1016 RC for bladder cancer (BCa) were completed at a single tertiary care institution. Demographical, clinical and pathological variables were recorded for each patient. The relationship between the number of removed LNs and the probability to find a LNI at definitive pathology examination was assessed by receiver operating characteristic (ROC) analyses. The ROC curve coordinates were used to graph the probability of finding LNI according to the number of LNs removed and examined with a …
