Pulsed radiofrequency (PRF) has been used for the treatment of radicular pain, due to a herniated intervertebral disc, but so far the data are anecdotal. This is a retrospective study on 13 consecutive patients with this type of pain, at levels L3 to S1. All patients had a diagnosis confirmed by imaging, all had neurological abnormalities, and all were scheduled for surgical intervention. ⋯ Neurological abnormalities resolved except in one patient, who had decreased sensibility in a small area in the L3 dermatome at the last follow-up. All professionally active patients went back to work after 0.49 months (0.1 to 1). It is concluded that PRF may potentially be a viable alternative for epidural steroid injections in the treatment of acute radicular pain, due to a herniated intervertebral disc, and that further studies, including a control group, should be carried out to establish the value of this method.

Chronic pain has only recently been recognized as an important health care issue. There is no widely shared agreement as to the best ways to diagnose and treat chronic pain patients. ⋯ The current chaotic state confuses patients, health care providers, and payers. It is possible that pain management may disappear from health care if we do not improve our understanding of chronic pain and how to best treat those who suffer.

The increased use of opioids in the treatment of chronic pain encourages the search for drugs with low abuse and tolerance potential but with potent analgesic activity. Opioid agonist-antagonists and partial agonists have less abuse potential than do mu opioid receptor agonists such as morphine, and have been used for many years for their analgesic affects. ⋯ Doctors are often hesitant to prescribe agonist-antagonists and partial agonists to opioid-tolerant patients, fearing that these drugs may precipitate withdrawal. Can drugs being used safely for addiction treatment also safely replace opioid agonists to provide analgesia in chronic pain patients who are opioid-tolerant?

Availability of opiate substances through physicians and on the street has led to a rise in dependence and in addiction resulting in countless numbers of people hooked on these drugs. Long-term use of these agents results in reduction of endogenous supply of opiate replaced by these exogenous compounds. A technique known as Ultrarapid Detoxification (UROD) has been developed and appears more promising than conventional modalities. ⋯ Though techniques vary from center to center, safety should be paramount with the technique performed in an intensive care unit with trained professional anesthesiologists. Psychosocial issues should be evaluated by a trained addictionalist and most people will succeed from the UROD procedure without experiencing the horrible withdrawal syndrome. Patients must have realistic goals and be prepared to deal with psychosocial issues post-procedure.

Nonradicular low back pain can be a difficult entity to accurately diagnose and treat. Facet joints, muscle, ligaments, and fascia have all been reported to be etiologies of acute and chronic low back pain. However, the facet joint as a source of low back pain is controversial. The diagnosis of facet joint pain is made by diagnostic facet joint or median nerve branch injections with a local anesthetic. The purpose of this study was to determine if the results of diagnostic facet joint injections are influenced by the technique used to perform these injections. ⋯ The results of this study demonstrated that local anesthetic injections are useful for the diagnosis of nonradicular low back pain but may yield false positive results with respect to lumbar facet pain depending upon the technique utilized.
