Prevalence of Cardiovascular Disease and Osteoporosis During Androgen Deprivation Therapy Prescription Discordant to EAU Guidelines: Results From a Multicenter, Cross-sectional Analysis From the CHOsIng Treatment for Prostate canCEr (CHOICE) Study.

Objective: To analyze the prevalence of cardiovascular disease (CVD) and osteoporosis in patients treated with androgen deprivation therapy (ADT) for prostate cancer (PCa) but not adherent to European Association of Urology (EAU) guidelines.

Materials And Methods: The CHOosIng Treatment for Prostate CanCEr (CHOICE) study was an Italian multicenter, cross-sectional study conducted from December 2010 to January 2012. A total of 1386 patients treated with ADT for PCa (first prescription or renewal of ADT) were selected.

Celecoxib for the prevention of nonmuscle invasive bladder cancer: results from a matched control study.

Objectives: New targets and approaches are under investigation for the treatment of nonmuscle invasive bladder cancer (NMIBC). Preclinical data suggest cyclooxygenase-2 (COX-2) as a promising target. Celecoxib, a COX-2 selective inhibitor, inhibits tumor development and enhances survival, both in vitro and in vivo models of bladder cancer.

[Urethral injuries secondary to implantation of penile prosthesis. Analysis of the causes, prevention and treatment].

Urethral injuries due to penile prosthesis implant represent a rare complication of the intervention to position penile prosthesis, but unfortunately scientific literature about this is poor. This rare complication may occur during surgery and in the postoperative period, both early and late. It recognizes a variety of causes that may include anatomical or functional conditions, for example cavernosal fibrosis or outcomes of inflammations or previous urethral lesions and pathological sensibility due to diabetic neuropathy or other forms of neuropathy including those from spinal cord injury or myelopathy.

Long term patient satisfaction and quality of life with AMS700CX inflatable penile prosthesis.

Objective: Penile prosthesis implantation is the solution of choice in patients who have failed or present contraindication to the use of all conservative treatment for erectile dysfunction (ED). Overall, satisfaction rates are high, with more than 80% of patients and partners fully satisfied with cosmetic and functional result of surgery. Chronic postoperative pain, penile shortening, soft or hyposensitive glans, pencil like penis syndrome and difficulty to cycle the device represent the most common causes of patient's dissatisfaction.

The interaction of celecoxib with MDR transporters enhances the activity of mitomycin C in a bladder cancer cell line.

Background: An in vitro model was developed to understand if celecoxib could synergize with Mitomycin C (MMC), commonly used for the prevention of non-muscle invasive bladder cancer recurrence, and eventually elucidate if the mechanism of interaction involves multi drug resistance (MDR) transporters.

Methods: UMUC-3, a non COX-2 expressing bladder cancer cell line, and UMUC-3-CX, a COX-2 overexpressing transfectant, as well as 5637, a COX-2 overexpressing cell line, and 5637si-CX, a non COX-2 expressing silenced 5637 cell line, were used in the present study. The expression of COX-2 and MDR pumps (P-gp, MDR-1 and BCRP) was explored through western blot.

[Urethroplasty in hypoplastic-dysplastic corpus spongiosum and short urethra].

Congenital penile curvature and chordee are a rare malformative condition most frequently associated with hypospadias, but varying degrees of penile curvature are observed with an orthotopic meatus. Disease becomes evident after puberty, when curvature becomes more apparent with erection. We present a case of a young man (16 years old), with ventral congenital penile curvature without hypospadias and with hypoplastic-dysplastic corpus spongiosum and short urethra, who could not have normal sexual intercourses.

Bicalutamide failure in prostate cancer treatment: involvement of Multi Drug Resistance proteins.

Prolonged bicalutamide treatment induced pathology regression although relapses with a more aggressive form of prostate cancer have been observed. This failure could be due to androgen receptor mutation. In the present work we hypothesized an alternative mechanism responsible for bicalutamide failure involving activity of ATP-binding cassette (ABC) pumps such as P-glycoprotein, Breast Cancer Receptor Protein (BCRP), and Multi Resistant Proteins (MRPs) that extrude the androgen antagonist from the cell membrane.

Quality of life evaluation by the EORTC QLQ-C30 questionnaire in patients treated with hormonal treatment in Italy. A QuABIOS group study.

Objectives: An observational study was planned by the QuABIOS group, to survey the hormonal treatment administered to prostate cancer patients in Italy within a time window of 12 months. We report here a prospective quality of life (QOL) evaluation over time and by hormonal treatment modalities.

Methods: Patients with diagnosis of prostate cancer and treated with hormonal therapy were eligible for this study.

Human epididymal and prostatic tracts of vas deferens: different contraction response to noradrenaline stimulation in isolated organ bath assay.

In the present study epididymal and prostatic portions of human vas deferens were separately isolated and stimulated with exogenous noradrenaline to study their contractile properties. The results displayed that the epididymal tract produced a phasic-tonic response, while the prostatic strip produced only a phasic response suggesting a different functional role of each vas deferens segment. Moreover, it has been verified if alpha(1)-adrenoceptor antagonists doxazosin, alphuzosin and terazosin could differently block the noradrenaline response in each segment.

Contrast-enhanced multislice pneumo-CT-cystography in the evaluation of urinary bladder neoplasms.

Purpose: To evaluate the accuracy of contrast-enhanced multislice CT (MSCT) in the study of urothelial tumors after distension of the bladder with air.

Materials And Methods: We evaluated 43 consecutive patients with endoscopically proven bladder lesions. After air distension of the bladder, unenhanced pelvic and enhanced abdomino-pelvic scans were obtained with the following protocol: thickness 2.

Penile Doppler ultrasound assessment of the cavernous arteries.

Objective: To evaluate the possible relationship between the basal and dynamic diameter of the cavernous arteries and altered peak diastolic (PDV) and systolic values (PSV) in patients undergoing penile Doppler ultrasound for differential diagnosis of erectile dysfunction (ED).

Materials And Methods: From December 2003 to December 2004 we examined 132 consecutive patients suffering from erectile dysfunction and 30 controls. All patients underwent penile Doppler ultrasound in basal and dynamic conditions and all the examinations were performed by measurements of the cavernous arteries diameters in basal and dynamic conditions.

Correlation between sigma2 receptor protein expression and histopathologic grade in human bladder cancer.

Sigma2 (sigma2) receptor proteins are overexpressed in several tissues and tumour cell lines. Although the biomolecular mechanism of this overexpression must be elucidated, sigma2 receptor was considered a potential biomarker for monitoring solid tumour proliferation. In this study, we verified first sigma2 receptor overexpression by saturation analysis with radioligand in six human bladder cancer specimens, then if a possible correlation could be established between sigma2 overexpression and tumour tissue stage and grade.

[Tolerability to transperineal prostatic biopsy based on the number of specimens].

Prostate biopsy is a fundamental step in the diagnostic flow chart of prostate cancer. We have evaluated the influence of the number of cores taken on the tolerability and morbidity of the transperineal ultrasound-guided prostate biopsy. We have compared a group of 240 pts undergone 16 core prostate biopsy to an historical cohort of 100 pts undergone 10 core prostate biopsy.

[Incontinence after retropubic radical prostatectomy: correlation between ultrasonographic morphological data and urodynamic parameters].

Objective: The aim of this study is to evaluate the relationships existing between transrectal ultrasound and urodynamics in patients undergone radical retropubic prostatectomy and affected by stress incontinence.

Materials And Methods: 78 patients were suitabe for the study. They have been divided in three groups: group A, 18 incontinent patients (at least 1 pad a day); group B, 30 patients with occasional dribbling (no incontinence device needed); group C, 30 continent patients.

[Role of power Doppler in the differential diagnosis between organic and functional cavernovenous insufficiency in patients with erectile maintenance deficiency].

Dynamic penile eco colorDoppler (ECDP) shows limits of specificity in case of differential diagnosis between functional (adrenergic hypertone) and organic cavernovenous incompetence. The aim of this study is the evaluation of a new flow chart for venogenic erectile dysfunction diagnosis, including power Doppler (PD), avoiding the repetition of ECD with higher concentrations of PGE1. In fact this procedure is invasive, often painful and burdened by a consistent risk of priapism.
