A Small Group Randomized Double-Blind Placebo-Controlled Study to Evaluate the Efficacy of Daily Pentoxifylline in the Management of Patients With Erectile Dysfunction with Suboptimal Treatment Response to Sildenafil.

Introduction: Several studies have reaffirmed the use of regular pentoxifylline therapy in increasing the penile brachial pressure index in men affected by erectile dysfunction when compared to placebo.

Aim: The aim of this study was to evaluate the efficacy of pentoxifylline as an adjunctive treatment for patients with erectile dysfunction.

Methods: This study was a single center, prospective, randomized, double-blind, placebo-controlled trial.

The Role of Vitamin D Receptor Polymorphisms in Predicting the Response to Therapy for Nonmuscle Invasive Bladder Carcinoma.

Purpose: Clinical and pathological predictors of bladder carcinoma recurrence and progression are relatively well defined. However, there is a paucity of genetic data specifically on the association of single nucleotide polymorphisms in specific genes for predicting recurrence and progression following immunotherapy. The VDR gene was found to regulate the immunomodulatory effects of vitamin D and it enhances the innate immunity system.

Metabonomic profiling of bladder cancer.

Early diagnosis and life-long surveillance are clinically important to improve the long-term survival of bladder cancer patients. Currently, a noninvasive biomarker that is as sensitive and specific as cystoscopy in detecting bladder tumors is lacking. Metabonomics is a complementary approach for identifying perturbed metabolic pathways in bladder cancer.

Urinary metabotyping of bladder cancer using two-dimensional gas chromatography time-of-flight mass spectrometry.

Cystoscopy is the gold standard clinical diagnosis of human bladder cancer (BC). As cystoscopy is expensive and invasive, it compromises patients' compliance toward surveillance screening and challenges the detection of recurrent BC. Therefore, the development of a noninvasive method for the diagnosis and surveillance of BC and the elucidation of BC progression become pertinent.
