Chronic pain is a major public health problem resulting in physical and emotional pain for individuals and families, loss of productivity, and an annual cost of billions of dollars. The lack of objective measures available to aid in diagnosis and evaluation of therapies for chronic pain continues to be a challenge for the clinician. ⋯ Functional connectivity, fMRI, chronic pain, chronic back pain, fibromyalgia, diabetic neuropathy, chronic regional pain syndrome.

Navigated percutaneous endoscopic cervical discectomy (PECD) is a promising minimally invasive surgery for treating cervical spondylotic radiculopathy. PECD has been described as a safe, effective, and minimally invasive method for patients with radiculopathy, but it comes with a steep learning curve. Due to the limited field of vision, anatomic localization is difficult for surgeons until using the O-arm based navigation. In this study, patients with radiculopathy due to foraminal disc herniation or foraminal stenosis in the lower cervical spine underwent the single level full endoscopic posterior cervical foraminotomy procedure assisted by O-arm-based navigation. ⋯ Minimally invasive, cervical foraminotomy, endoscopic, navigation, O-arm, percutaneous endoscopic cervical discectomy.

Clinical Trial Observational Study
Pulsed Radiofrequency Ablation for the Treatment of Glossopharyngeal Neuralgia Secondary to Oropharyngeal Carcinoma.
The management of glossopharyngeal neuralgia due to oropharyngeal carcinoma is particularly difficult because of rich innervations of the area, erosive nature of neoplasm and dynamic pain evoked by the functional movements like swallowing and chewing. Few case reports have shown the efficacy of pulsed radiofrequency (PRF) treatment in primary and secondary glossopharyngeal neuralgia in non-cancer patients. However, the efficacy of PRF ablation of the glossopharyngeal nerve in oral cancer patients is not known. ⋯ Glossopharyngeal neuralgia, ear pain, odynophagia, oral cancer pain, pulsed radiofrequency ablation, side effects.

Levels of prescription opioid (PO) dispensing have been rising in Canada - also in global comparison - since the mid-2000s, and are co-occurring with extensive PO-related morbidity and mortality. Previous analyses have demonstrated correlations between PO dispensing and related harm levels, yet also distinct heterogeneous interprovincial PO-dispensing patterns, in regards to quantities and individual PO formulations. Several system-level interventions have been implemented recently (since 2012) to address high PO-use levels and related harms in Canada; the effects of these interventions on PO-dispensing levels remain largely unexamined. ⋯ Opioids, prescribing, dispensing, interventions, policy, population, monitoring, Canada.
