The aim of this study was to retrospectively review the chart of cancer patients switched to methadone for unfavorable response to the previous opioid. ⋯ Switching to methadone from different opioids, using an initial fixed ratio followed by a flexible dosing, according to the clinical need, is highly effective and safe when performed in an acute pain relief and palliative care unit. Further studies should assess this approach in other settings.

Randomized Controlled Trial
A randomized, placebo-controlled study to assess the efficacy of lateral branch neurotomy for chronic sacroiliac joint pain.
The objective of this study was to compare the efficacy of lateral branch neurotomy using cooled radiofrequency to a sham intervention for sacroiliac joint pain. ⋯ The treatment group showed significant improvements in pain, disability, physical function, and quality of life as compared with the sham group. The duration and magnitude of relief was consistent with previous studies, with current results showing benefits extending beyond 9 months.

The article aims to evaluate the long-term effectiveness and safety of pulsed radiofrequency (PRF) on the dorsal root ganglion (DRG) in patients with chronic cervical radicular pain refractory to repeated transforaminal epidural steroid injections (TFESIs). ⋯ Application of PRF to the DRG appears to be an effective and relatively safe intervention technique for chronic cervical radicular pain refractory to repeated TFESIs.
