Methods of blinding have been infrequently investigated. This study assessed data collector blinding within an investigation of endogenous pain modulation. ⋯ Collection of participants' pain responses led to frequent episodes of unblinding. However, it may be misleading to only consider the frequency of correct suspicions as successful or unsuccessful blinding.

Randomized Controlled Trial
Pain Perception in Healthy Young Men Is Modified by Time-Of-Day and Is Modality Dependent.
Several physiological processes exhibit 24-hour oscillations termed circadian rhythms. Despite numerous investigations on the circadian dynamics of pain perception, findings related to this issue remain inconsistent. This study aimed to assess the effect of time-of-day on multimodal experimental pain perception in healthy males, including "static" and "dynamic" quantitative sensory tests. ⋯ Thermal pain scores varies during the day and morning seems to be the time-of-day most insensitive to pain. Also, dynamic tests and the mechanical pain model are not appropriate for detecting diurnal variability in pain. The results of this study may be partially explained by a potential analgesic effect of some hormones known to have diurnal variation (e.g., melatonin and cortisol).

Randomized Controlled Trial Multicenter Study
Exploring the Role of Tanezumab as a Novel Treatment for the Relief of Neuropathic Pain.
Evaluate efficacy and safety of tanezumab, a humanized monoclonal antibody against nerve growth factor, in neuropathic pain. ⋯ Tanezumab provided effective pain reduction in DPN. In PHN, only the highest tanezumab dose reduced pain; treatment differences were not significant. No new safety concerns were observed despite preexisting neuropathy.

Multicenter Study Observational Study
Evaluation of a Telementoring Intervention for Pain Management in the Veterans Health Administration.
Half of all Veterans experience chronic pain yet many face geographical barriers to specialty pain care. In 2011, the Veterans Health Administration (VHA) launched the Specialty Care Access Network-ECHO (SCAN-ECHO), which uses telehealth technology to provide primary care providers with case-based specialist consultation and pain management education. Our objective was to evaluate the pilot SCAN-ECHO pain management program (SCAN-ECHO-PM). ⋯ SCAN-ECHO-PM was associated with increased utilization of physical medicine services and initiation of nonopioid medications among patients with CNCP. SCAN-ECHO-PM may provide a novel means of building pain management competency among primary care providers.
