The efficacy and safety of tadalafil, dosed once a day for the treatment of erectile dysfunction, was assessed in a randomized, double-blind, placebo-controlled, parallel-design study at 15 US centers. Following a 4-week treatment-free run-in period, patients (X18 years of age) were randomly assigned to 24 weeks treatment with tadalafil 2.5 mg, tadalafil 5 mg or placebo. Primary efficacy endpoints were change at 24 weeks in International Index of Erectile Function Erectile Function (EF) Domain score and mean per-patient percentage 'yes' responses to Sexual Encounter Profile diary questions 2 and 3. Tadalafil significantly improved erectile function compared with placebo for all three co-primary efficacy endpoints. Few patients discontinued because of adverse events (2.1%, placebo; 6.3%, tadalafil 2.5 mg; 4.1%, tadalafil 5 mg). Common treatment-emergent adverse events (X5%) were nasopharyngitis, influenza, viral gastroenteritis and back pain. Tadalafil 2.5 mg and 5 mg, dosed once a day for 24 weeks, was well tolerated and significantly improved erectile function.
Prostate-rectum hydrogel spacer application is a relatively safe technical procedure that is well tolerated and has a high technical success rate. Spacer application significantly reduces rectal radiation dose and results in long-term reductions in rectal toxicity, as well as improvements in bowel, urinary, and sexual QOL.
IntroductionTo evaluate the efficacy and safety of onabotulinumtoxinA for the treatment of neurogenic detrusor overactivity (NDO) in subpopulations of etiology (multiple sclerosis [MS] or spinal cord injury [SCI]) and concomitant anticholinergics (use/non-use).MethodsData were pooled from two double-blind, placebo-controlled, pivotal, phase 3 studies including a total of 691 patients with ≥14 urinary incontinence (UI) episodes/week due to MS (n = 381) or SCI (n = 310). Patients received intradetrusor injections of onabotulinumtoxinA 200U (n = 227), 300U (n = 223), or placebo (n = 241). Change from baseline at week 6 in UI episodes/week (primary endpoint), urodynamics, quality of life (QOL), and adverse events (AEs) were assessed.ResultsSignificant and similar reductions in UI episodes were observed regardless of etiology or anticholinergic use: at week 6, mean weekly decreases of −22.6 and −19.6 were seen in MS and SCI patients, respectively, and −20.3 and −22.5 in anticholinergic users and non-users, respectively, treated with onabotulinumtoxinA 200U. The 300U dose did not add to the clinical efficacy in any subpopulation. Similar proportions of patients achieved ≥50% or 100% reductions in UI episodes in all subgroups. Improvements in maximum cystometric capacity, maximum detrusor pressure during first involuntary detrusor contraction, and QOL were significant in both etiologies and were independent of anticholinergic use. The most common AEs in all groups were urinary tract infection and urinary retention.ConclusionRegardless of concomitant anticholinergic use or etiology, onabotulinumtoxinA significantly improved UI symptoms, urodynamics, and QOL in patients with UI due to NDO. OnabotulinumtoxinA was well tolerated in all groups.

OBJECTIVE
To evaluate the efficacy of vardenafil in patients previously unresponsive to sildenafil.
PATIENTS AND METHODS
A multicentre, double‐blind, 12‐week, flexible‐dose, placebo‐controlled trial was conducted, involving 463 men aged ≥ 18 years with moderate‐to‐severe erectile dysfunction (ED) and who were unresponsive to sildenafil (by history). After a 4‐week treatment‐free run‐in, patients received placebo or vardenafil 10 mg with the option to maintain current dose or to titrate by one dose level (5, 10 or 20 mg) based on efficacy and tolerability at 4 and 8 weeks. Outcome measures were the erectile function (EF) domain score of the International Index of Erectile Function, two Sexual Encounter Profile diary questions (vaginal penetration and maintenance of erection until successful completion of intercourse), and the Global Assessment Question (GAQ).
RESULTS
There was significantly better EF with vardenafil than with placebo throughout the study. The least‐square mean EF domain scores increased from 9.3 at baseline to 17.6 at the ‘last’ observation carried forward (LOCF) analysis with vardenafil (P < 0.001). Overall least‐square mean per‐patient success rates more than doubled for penetration (30.3% to 62.3%) and quadrupled for successful intercourse (10.5% to 46.1%) with vardenafil. Improved erections (positive response to the GAQ) were reported by 61.8% of patients receiving vardenafil and 14.7% of those receiving placebo at LOCF (P < 0.001). Normal EF (domain score ≥ 26) was achieved by 30% of patients receiving vardenafil and 6% receiving placebo at LOCF (P < 0.001). Adverse events were infrequent and representative of the phosphodiesterase‐5 inhibitor profile.
CONCLUSION
Vardenafil is an effective and generally safe treatment for ED, even in men unresponsive to sildenafil (by history).
The efficacy of onabotulinumtoxinA and solifenacin was significantly higher than that of placebo. However, onabotulinumtoxinA showed significantly greater decreases in urinary incontinence than solifenacin with a third of patients achieving a 100% incontinence reduction. No unexpected safety signals were observed.
The Consortium of Multiple Sclerosis Centers (CMSC) convened a Framework Taskforce composed of a multidisciplinary group of clinicians and researchers to examine and evaluate the current models of care in multiple sclerosis (MS). The methodology of this project included analysis of a needs assessment survey and an extensive literature review. The outcome of this work is a two-part continuing education series of articles. Part 1, published previously, covered the updated disease phenotypes of MS along with recommendations for the use of disease-modifying therapies. Part 2, presented herein, reviews the variety of symptoms and potential complications of MS. Mobility impairment, spasticity, pain, fatigue, bladder/bowel/sexual dysfunction, cognitive dysfunction, and neuropsychiatric issues are examined, and both pharmacologic and nonpharmacologic interventions are described. Because bladder and bowel symptoms substantially affect health-related quality of life, detailed information about elimination dysfunction is provided. In addition, a detailed discussion about mental health and cognitive dysfunction in people with MS is presented. Part 2 concludes with a focus on the role of rehabilitation in MS. The goal of this work is to facilitate the highest levels of independence or interdependence, function, and quality of life for people with MS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
