Randomized Controlled Trial
Rapid local anesthesia in humans using minimally invasive microneedles.
This study tested the hypothesis that minimally invasive microneedles cause less pain during injection of lidocaine, but induce local anesthesia in humans with the same rapid onset and efficacy as intradermal lidocaine injection using hypodermic needles. ⋯ This study demonstrates for the first time that microneedle-based lidocaine injection is as rapid and as effective as hypodermic injection in inducing local anesthesia while resulting in significantly less pain during injection.

Although pain is commonly experienced by cancer patients, many receive inadequate pain management. Little data exist quantifying analgesic usage among oncology patients. This study evaluates perceived causes of pain and investigates reasons why oncology patients fail to receive optimal pain management. ⋯ Most cancer patients perceive pain from their disease or treatment, regardless of therapy received. Many, however, did not use analgesics due to concerns of addiction, cost, or lack of health care provider endorsement. Providers should regularly discuss pain symptoms and management with cancer patients.

Is pain catastrophizing a stable trait or dynamic state in patients scheduled for knee arthroplasty?
This study sought to clarify whether pain-related catastrophizing is a response that varies given a specific situational circumstance (state) or an enduring personality construct (trait). ⋯ These data provide preliminary support for the notion that pain-related catastrophizing is a dynamic construct that is related to pain intensity.

Randomized Controlled Trial
An online self-help CBT intervention for chronic lower back pain.
Research has shown that cognitive and behavioral therapies can effectively improve quality of life in chronic pain patients. Unfortunately, many patients lack access to cognitive and behavioral therapy treatments. We developed a pilot version of an interactive online intervention to teach self-management skills for chronic lower back pain, a leading cause of disability and work absenteeism. The objective of this randomized, controlled trial was to evaluate its efficacy. ⋯ Use of this pilot intervention seems to have had positive effects on a number of pain-related outcomes, including disability. Future research will evaluate the effectiveness of the completed intervention, with particular attention to quality of life and disability.

To determine whether patients with myogenous and mixed temporomandibular disorders (TMD) have greater fatigability of the cervical extensor muscles while performing a neck extensor muscle endurance test (NEMET) when compared with healthy controls. ⋯ These results highlight the fact that alterations of endurance capacity of the extensor cervical muscles could be implicated in the neck-shoulder disturbances presented in patients with TMD.
