Evidence for opioid-induced hyperalgesia (OIH) has been shown in animal and human studies, but the clinical implications of this phenomenon remain unclear. ⋯ The results of this study suggest that opioid medication is an important contributing factor to pain perception accompanying LA injection, and cancer patients using high-dose opioids may be highly susceptible to hyperalgesic responses to this clinical stimulus. We also suggest that the possible presence of OIH may be intensified among cancer patients with poor physical and psychosocial functional status.

Magnetic resonance imaging of the lumbar spine in a patient with a spinal cord stimulator.
The use of magnetic resonance imaging (MRI) is continuously escalating for the evaluation of patients with persistent pain following lumbar spine surgery (LSS). Spinal cord stimulation (SCS) therapy is being clinically applied much more commonly for the management of chronic pain following LSS. There is an increased probability that these 2 incompatible modalities may be accidentally used in the same patient. ⋯ This case demonstrates the lack of compatibility of lumbar MRI and the Precision SCS system as well as one of the possible patient adverse events that can occur when patients are exposed to MRI outside of the approved device labeling.
