Idiopathic trigeminal neuralgia (ITN) can be effectively treated with radiofrequency thermocoagulation. However, this procedure requires cannulation of the foramen ovale, and conventional cannulation methods are associated with high failure rates. Multimodality imaging can improve the accuracy of cannulation because each imaging method can compensate for the drawbacks of the other. We aim to determine the feasibility and accuracy of percutaneous foramen ovale cannulation under the guidance of virtual navigation with multimodality image fusion in a self-designed anatomical model of human cadaveric heads. ⋯ Virtual navigation with multimodality image fusion can substantially facilitate foramen ovale cannulation and is worthy of clinical application.

Over the past 50 years, the field of chronic pain has witnessed an evolution of psychological approaches with some notable success. Some of this evolution has included "mindfulness-based interventions" (MBIs), now regarded as having encouraging partial support for their effectiveness. However, several theoretical challenges remain that may inhibit the progress of MBIs. These challenges include a lack of clarity surrounding the mindfulness construct itself, the proliferation of purported underlying mechanisms arising from different theories, and limited evidence for the mechanisms through which MBIs work. The current conceptual review provides a critique of existing theoretical models of mindfulness that have been applied to understanding and treating chronic pain. ⋯ Based on this assessment, a summary of available evidence for a particular contextual behavioral theory of "mindfulness"-psychological flexibility-is outlined. Findings show the need for further integration of existing mindfulness constructs to better guide development and evaluation of mindfulness-based treatment methods in the future.

To investigate the predictive power of resilience and vulnerability factors in relation to pain-related disability. ⋯ Patients with acute back pain who show high levels of pain-related disability, pain intensity, and fear avoidance beliefs are at risk of developing back pain-related disability and should be the target of a preventive intervention.
