Randomized Controlled Trial
Subcutaneous tanezumab for osteoarthritis: Is the early improvement in pain and function meaningful and sustained?
To evaluate if early improvements in pain and function with subcutaneous tanezumab are meaningful and sustained over 24 weeks. ⋯ This exploratory analysis of data from a placebo-controlled, Phase 3 study of patients with moderate-to-severe osteoarthritis of the hip or knee for whom standard analgesics were not effective or could not be taken, found that onset of efficacy of subcutaneous tanezumab was within the first week, and efficacy was maintained through the 24-week treatment period. Tanezumab was effective in those patients with the most radiologically severe osteoarthritis.

Case Reports
Expanding frontiers in telehealth: video assisted at-home application of capsaicin 8% patch.
In recent years, the delivery of health services has undergone a major paradigm shift towards expanded outpatient services and widespread use of telemedicine. Post-herpetic neuralgia (PHN) is a treatment recalcitrant neuropathic pain condition referring to pain persisting more than three months from the initial onset of an acute herpes zoster. QUTENZA® (capsaicin 8% patch) is a single 1-hr localized treatment for PHN and can provide several months of pain relief per application. ⋯ SIGNIFICANCE: This is a case report of the successful treatment of post-herpetic neuralgia at-home using Capsaicin 8% patch. The procedure was performed under full supervision and instruction from a physician using video telehealth services. Not only did the patient tolerate the procedure and have significant efficacy, she voiced preference to repeat treatment in this manner versus going back to the office.

This study aims to evaluate the efficacy of 10-kHz high-frequency (HF10) devices as a rescue treatment in patients with failure of conventional spinal cord stimulation (SCS) therapy for chronic pain without the need to change the spinal hardware. ⋯ This study shows that high-frequency stimulation may be useful in patients with failure of conventional tonic stimulation for chronic pain, both in the trial phase and in previously implanted subjects. The novelty of this study lies in the use of the implanted epidural electrodes, which avoids the need for further surgery. The results in terms of pain control and recovery of functionality are satisfactory. In addition, variables such as male gender and high body mass index could be predictors of therapy failure.

Together, neck pain and back pain are the first cause of disability worldwide, accounting for more than 10% of the total years lived with disability. In this context, chiropractic care provides a safe and effective option for the management of a large proportion of these patients. Chiropractic is a healthcare profession mainly focused on the spine and the treatment of spinal disorders, including spine pain. ⋯ SIGNIFICANCE: Spinal manipulation inhibits back and neck pain partly through spinal segmental mechanisms and potentially through peripheral mechanisms regulating inflammatory responses. Other mechanisms remain to be clarified. Controls and placebo interventions need to be improved in order to clarify the contribution of specific and non-specific effects to pain relief by spinal manipulative therapy.

Pain expectation and controllability can modulate pain processing. However, little is known about age-related effects on these cognitive factors involved in pain control. This study assessed age-related brain changes associated with pain expectation and controllability. ⋯ This research describes the impact of age on cognitive pain modulation evoked by the manipulation of pain controllability and pain expectations. Our findings constitute a first step in the understanding of the greater vulnerability of older individuals to chronic pain. Moreover, we show that older adults can benefit from cognitive pain control mechanisms to increase the efficacy of pain treatments.
