The goal of this study is to demonstrate the feasibility of simultaneous [18F]-fluorodeoxyglucose (FDG) positron emission tomography (PET) and magnetic resonance imaging (MRI) for noninvasive visualization of muscular, neurovascular, and skin changes secondary to complex regional pain syndrome (CRPS). ⋯ The increased uptake of [18F]FDG in the symptomatic areas likely reflects the increased metabolism due to the inflammatory response causing pain. Therefore, our approach combining metabolic [18F]FDG PET and anatomic MR imaging may offer noninvasive monitoring of the distribution and progression of inflammatory changes associated with CRPS.

Randomized Controlled Trial
Effects of a low-carbohydrate ketogenic diet on reported pain, blood biomarkers and quality of life in patients with chronic pain: A pilot randomised clinical trial.
A low-carbohydrate ketogenic diet has been reported to improve chronic pain by reducing inflammation, oxidative stress, and sensitivity within the nervous system. The main aim of this trial is to evaluate the effects of a ketogenic diet on reported pain, blood biomarkers and quality of life in patients with chronic pain. ⋯ The implementation of a whole-food diet that restricts ultra-processed foods is a valid pain management tool; however, a low-carbohydrate ketogenic diets may have potentially greater pain reduction, weight loss and mood improvements.

Observational Study
Pain location is associated with fracture type in acute osteoporotic thoracolumbar vertebral fracture: a prospective observation study.
This study investigated the relationship between pain location and fracture type in patients with acute osteoporotic vertebral fracture (OVF). ⋯ For patients with acute OVF, the site of pain is related to the type of fracture. The pain at the fracture site is more often observed in the central type and burst type of fractures, whereas pain at a non-fracture site is more often observed in the upper and lower endplate types of fractures. Additionally, when OVF is suspected, radiological assessment of the thoracic and lumbar spine is recommended to better detect fractures that could cause pain distal to the site of the fracture.

To establish the efficacy of medications, incidence of adverse events (AEs), and withdrawal rates associated with the pharmacological management of chronic spinal cord injury pain. ⋯ Pregabalin was found to be effective for neuropathic pain vs placebo. Cannabinoids were ineffective for neuropathic pain. AEs are a common cause for withdrawal. The nature of AEs was poorly reported, and AE reporting should be improved in future randomized controlled trials.

Randomized Controlled Trial
A Randomized controlled trial of the Sources of Meaning Card Method: A new meaning-oriented approach predicts depression, anxiety, pain acceptance, and crisis of meaning in chronic pain patients.
Although considered the first-line psychological treatment for chronic pain, cognitive behavioral therapy has recently been criticized as being too limited, insufficient, and sometimes ineffective in the treatment of patients with chronic pain. Moreover, important existential perspectives are sparsely or not at all integrated into cognitive behavioral therapy. We therefore propose to complement chronic pain treatment with a meaning-based intervention, the Sources of Meaning Card Method (SoMeCaM). This study tested its efficacy. ⋯ Our preliminary work demonstrates the importance of the existential perspective in chronic pain therapy.
