Comparative Study Controlled Clinical Trial
An exploratory analysis on the effectiveness of four strong opioids in patients with cancer pain.
This analysis, carried out in the context of a wider observational prospective study, tried to explore whether four World Health Organization/step-III opioids (morphine, oxycodone, fentanyl, and buprenorphine) had different effectiveness when using several different outcomes and endpoints. ⋯ The observed results, even if the small sample size and the nature itself of the study do not allow a definitive evaluation of the effectiveness of the drugs, underline a degree of variability among opioids and address toward a correct planning of a comparative randomized clinical trial that is now underway in Italy. For this reason, a confirmative effectiveness randomized controlled trial is required.

Muscle fatigue is prevalent in acute and chronic musculoskeletal pain conditions in which myofascial trigger points (MTPs) are involved. The aim of this study was to investigate the association of latent MTPs with muscle fatigue. ⋯ A latent MTP is associated with an accelerated development of muscle fatigue and simultaneously overloading active motor units close to an MTP. Elimination of latent MTPs and inactivation of active MTPs may effectively reduce accelerated muscle fatigue and prevent overload spreading within a muscle.

Randomized Controlled Trial Comparative Study
A randomized trial of epidural analgesia followed by continuous femoral analgesia compared with oral opioid analgesia on short- and long-term functional recovery after total knee replacement.
The purpose of this study was to compare continuous femoral nerve analgesia to oral opioid analgesics after discontinuation of epidural analgesia following total knee replacement. ⋯ CFA for 24 hours following discontinuation of epidural analgesia was associated with lower pain scores, greater compliance with physical therapy, increased range of motion, reduced opioid analgesia use, and greater patient satisfaction during hospitalization. The increased flexion of the operated joint was still evident at 1 month postoperatively.
