Aberrant analgesic response to medial branch blocks in patients with characteristics of fibromyalgia.
Facet interventions for spine pain have high failure rates, and preprocedural prediction of response is nearly impossible. A potential explanation may be aberrant central pain processing as that existing in conditions like fibromyalgia. To test this hypothesis, we conducted a retrospective study investigating the impact of having characteristics of fibromyalgia on the acute analgesic response to a first diagnostic medial branch block (MBB). ⋯ Characteristics of fibromyalgia may indicate pain that is more centralized in nature, a factor that may explain the aberrant analgesic response to this peripheral intervention. This may have implications for future prediction of treatment response, although prospective studies are needed.

Recent attention has focused on resilience as an important process in the experience and management of chronic pain. In this context, resilience is considered as a psychological factor that promotes adaptive responses to pain and pain-related life adversities. Current research suggests that it is a relevant variable in the prediction of pain adjustment among chronic pain patients. Recently, it was adapted the Resilience Scale to patients suffering chronic musculoskeletal pain (RS-18). The aims of this study were to confirm the internal structure of the RS-18 and to present new empirical evidence regarding its validity. ⋯ These findings give empirical support to the consideration of resilience as a protective variable in chronic pain adjustment and highlight the consideration that improving resilient behaviour could be an important target for the treatment of pain patients.

We report on a patient with an unusual cause of non-discogenic sciatica. ⋯ The present case suggested that an intrapiriformis lipoma can cause secondary piriformis syndrome and medical practitioners should be aware of this condition and consider lipomas and other occupying lesions of the pelvic muscles as a differential diagnosis in patients presenting with radicular pain.

Pain interventionists can interrupt pain through anesthetic blockade of neural transmission to virtually any part of the body. Temporary pain relief can be achieved by the direct application of targeted anesthetic. Diagnostically, nerve blocks help identify specific pain generators, refine differential diagnosis, and disrupt the neural transmission mechanisms to stop pain generation peripherally. ⋯ This study's results support the hypothesis that a combined interventional and cognitive motivational counseling treatment program can be effective in decreasing spine pain, reducing prescription pain medication use, and improving overall quality of life in chronic spine pain patients.
