Randomized Controlled TrialPercutaneous tibial nerve stimulation effects on detrusor overactivity incontinence are not due to a placebo effect: a randomized, double-blind, placebo controlled trial.
This is a prospective, double-blind, placebo controlled study, based on an original placebo technique, performed to evaluate the efficacy of percutaneous tibial nerve stimulation in female patients with detrusor overactivity incontinence. ⋯ Percutaneous tibial nerve stimulation can be considered an effective treatment for detrusor overactivity incontinence with 71% of patients considered responders, while none of those treated with placebo was considered a responder. The relevance of a placebo effect seems to be negligible in this patient population.

Randomized Controlled Trial Multicenter StudyBacillus Calmette-Guérin with or without interferon α-2b and megadose versus recommended daily allowance vitamins during induction and maintenance intravesical treatment of nonmuscle invasive bladder cancer.
In a multicenter, prospectively randomized study we evaluated bacillus Calmette-Guérin alone vs bacillus Calmette-Guérin plus interferon α-2b and megadose vitamins vs recommended daily allowance vitamins during induction and maintenance intravesical therapy in the treatment of nonmuscle invasive bladder cancer. ⋯ Interferon α-2b added to bacillus Calmette-Guérin induction and maintenance intravesical therapy did not decrease tumor recurrence in bacillus Calmette-Guérin naïve cases, but was associated with increased fever and constitutional symptoms. No difference in time to recurrence was present in patients receiving recommended daily allowance vs high dose vitamins.
