Clinical Trial
CT-guided percutaneous infrazygomatic radiofrequency neurolysis through foramen rotundum to treat V2 trigeminal neuralgia.
Percutaneous radiofrequency thermocoagulation or neurolysis of Gasserian ganglion through foramen ovale (FO) is the classical approach to treat trigeminal neuralgia (TN). However, it has been technically challenging when individual trigeminal sub-branch nerve block is desired through this approach. We have thus developed a novel computed tomograph-guided technique to block the V2 trigeminal nerve through foramen rotundum (FR). With this technique, we have conducted a study of 27 patients with isolated V2 TN. We hypothesize that this new technique will have comparable clinical outcome with the conventional FO approach. ⋯ We have developed a novel technique to selectively block the V2 trigeminal nerve at FR. This novel FR approach may be a good alternative to the classical FO approach when an isolated V2 branch block is desired.

Randomized Controlled Trial Observational Study
Aberrant drug-related behavior observed during a 12-week open-label extension period of a study involving patients taking chronic opioid therapy for persistent pain and fentanyl buccal tablet or traditional short-acting opioid for breakthrough pain.
Evaluate aberrant drug-related behaviors in patients administering fentanyl buccal tablet or traditional short-acting opioids for breakthrough pain. ⋯ Incidence of aberrant drug-related behaviors was similar between patients taking fentanyl buccal tablet and traditional short-acting opioids over 12 weeks.

The objective of this study is to assess clinical variables that may be associated with risk for opioid misuse in individuals with chronic pancreatitis. ⋯ Depression, quality of life, pain intensity and alcohol use may be good candidate variables for prospective studies to determine clinical risk factors for opioid misuse among patients with pancreatitis.

This study aims to evaluate correlates of gait speed, a measure of disability, in older adults with advanced knee osteoarthritis (OA) and chronic pain. ⋯ In a cross-sectional study of older adults with advanced knee OA and chronic pain, we found that age, arthritis function self-efficacy, and opioid use (but not dose) were significantly associated with decreased gait speed.
