Multicenter Study
Interobserver variation in grading and staging of squamous cell carcinoma of the penis in relation to the clinical outcome.
To examine interobserver variations in assessing grade and stage of penile squamous cell carcinoma (SCC). ⋯ Accurate histological subtyping by the surgical pathologist demands standardized guidelines, in particular for histological grading, which is crucial for clinical treatment, but shows significant interobserver variation.

To retrospectively review hypogonadal men receiving testosterone replacement therapy (TRT), and evaluate the changes in prostate-specific antigen (PSA) levels over an extended period, and thus evaluate the occurrence of prostate cancer, as a primary concern in treating late-onset hypogonadism (LOH) is the potential increased risk of prostate cancer; we also recorded the cardiovascular effects of TRT. ⋯ LOH is an increasingly prevalent disease characterized by a symptomatically low testosterone level, and TRT is effective in normalizing serum testosterone levels, providing a beneficial cardiovascular effect, and improving sexual function and overall quality of life. PSA levels remain stable after normalization of testosterone for > or =5 years, prostate cancer can be effectively diagnosed and treated in men taking TRT, and the incidence of prostate cancer among men with LOH on TRT is no greater than that in the general population.

Randomized Controlled Trial Multicenter Study
PSD502 improves ejaculatory latency, control and sexual satisfaction when applied topically 5 min before intercourse in men with premature ejaculation: results of a phase III, multicentre, double-blind, placebo-controlled study.
To determine the effect of PSD502 applied topically 5 min before intercourse on the Index of Premature Ejaculation (IPE) and intravaginal ejaculatory latency time (IELT) of men with lifelong premature ejaculation (PE) defined according to the International Society of Sexual Medicine (ISSM) definition; secondary objectives were to evaluate the safety and tolerability of PSD502 in patients with PE, and their sexual partners. ⋯ PSD502 applied topically 5 min before intercourse improved ejaculatory latency and significantly improved ejaculatory control and sexual satisfaction, factors relevant for acceptance of a PE treatment by both patient/physician and regulatory authorities. PSD502 was well tolerated by both patients and partners, with no systemic side-effects and a low incidence of localized effects, and was rated favourably by most users. PSD502 therefore appears to offer significant advantages over other therapies in development for the treatment of PE.

To investigate the effects of intravesical electrical stimulation (IVES) on bladder function and synaptic neurotransmission in the lumbosacral spinal cord in the spinalized rat, as the clinical benefits of IVES in patients with increased residual urine or reduced bladder capacity have been reported but studies on the mechanism of IVES have mainly focused on bladder A delta afferents in central nervous system-intact rats. ⋯ Our results suggest that IVES might affect voiding contractions in addition to inhibiting C-fibre activity and that IVES seems to have a more complex effect on the bladder control pathway. For synaptic neurotransmission in the spinal cord, IVES could possibly shift the balance between excitation and inhibition towards inhibition.
