Intrathecal analgesia (ITA) is a valuable treatment option for refractory cancer-related pain. However, there is still no general consensus on the analgesic effect of movement-evoked breakthrough pain (MEBTP) in the ITA setting. ⋯ In patients with refractory lower extremity cancer pain, ITAPP with PCIA was associated with improved pain control. Compared with conventional MEBTP regimens, appropriate ITAPP with PCIA provided superior analgesia and a much faster onset of action.

Efficacy of Cervical Facet Joint Radiofrequency Ablation Using a Multitined Cannula, a Technical Note, and Observational Study.
Chronic cervical facet joint pain is a leading cause of pain and disability. In patients nonresponsive to conservative treatment, cervical facet radiofrequency ablation (RFA) has shown to be efficacious. However, the conventional RFA technique can be cumbersome. A novel RFA technique with a multitined cannula allows for a lateral approach and represents an attractive alternative option for cervical facet RFA. It offers a potentially shorter, less cumbersome procedure, with consequently less x-ray exposure and patient discomfort than the conventional cervical RFA. ⋯ Our results suggest that cervical facet joint RFA using the novel technique with the multitined cannula results in significant pain reduction and improvement on the PGIC. While the conventional technique requires multiple ablations at each target level, the RFA with the multitined needle requires only a singular ablation, likely sparing time, radiation dose, discomfort, and costs. Our results merit consideration of replacement of the conventional technique with the novel technique using the multitined cannula. However, larger-scale clinical trials with an adequate long-term follow-up period are needed to prove the efficacy of RFA using the multitined cannula in cervical facet joint pain.

Alpha-Lipoic Acid, Palmitoylethanolamide, Myrrh, and Oxygen-Ozone Therapy Improve Pharmacological Therapy in Acute Painful Lumbosacral Radiculopathy due to Herniated Disc.
Neuropathic mechanisms largely contribute to radicular Low Back Pain (LBP) and an increase in oxidative stress is recognized as one of the possible causes of nerve damage, inducing axonal degeneration and myelin degradation of nerve fibers. ⋯ This study supports a multimodal approach combining nutraceutical supplements and O2-O3 therapy with pharmacological therapy in the treatment of acute radicular LBP secondary to disc herniation. The combination of neurotrophic and antioxidant therapies represents an etiopathogenetic approach, not purely symptomatic, that reduces symptomatology and avoids progression of the nerve damage.

Randomized Controlled Trial
Green Light-Based Analgesia - Novel Nonpharmacological Approach to Fibromyalgia Pain: A Pilot Study.
There continues to be significant reliance on pharmacological modalities for the management of chronic pain, with a particular focus on opioid analgesics as a singular option for pain management. Fibromyalgia is a prototypical central pain disorder, which is often used as a model to study chronic pain disorders. It has an estimated prevalence of approximately 1.1% to 5.4% in the general population. The widespread use of opioids in patients with fibromyalgia has been well demonstrated in several health claims database studies, with rates of use ranging from 11.3% to 69%. Minimizing opioid exposures reduces misuse risk, but requires adequate opioid-sparing multimodal analgesic strategies, particularly nonopioid analgesic adjuncts, to ensure effective treatment of pain, particularly high-impact pain. We chose fibromyalgia as our study population. Given that it is a disordered sensory processing condition, it may be particularly amenable to the beneficial effects of green-light therapy. ⋯ Our study demonstrated the feasibility of this treatment approach and study design and supports a future study to determine the efficacy of green light-based analgesia on opioid use, pain, and anxiety. While the reduction of opioid use was not of statistical significance, we believe it to be of clinical significance as there was no increase of patient-reported pain. This warrants further investigation in a large-scale trial of the use of green-light filtration of ambient light to mitigate opioid use and possible mediation of psychological impacts of pain with the use of green-lensed eyeglasses.
