Randomized Controlled Trial
Effect of fluoroscopically guided caudal epidural steroid or local anesthetic injections in the treatment of lumbar disc herniation and radiculitis: a randomized, controlled, double blind trial with a two-year follow-up.
Lumbar disc herniation and radiculitis are common elements of low back and lower extremity pain. Among minimally invasive treatments, epidural injections are one of the most commonly performed interventions. However, the literature is mixed about their effectiveness in managing low back and lower extremity pain. In general, individual studies and systematic reviews of epidural steroid injections have been hampered by their study design, baseline differences between treatment groups, inadequate sample sizes, highly controlled settings, lack of validated outcome measures, and the inability to confirm the injectate location because fluoroscopy was not used. ⋯ Caudal epidural injections of local anesthetic with or without steroids might be an effective therapy for patients with disc herniation or radiculitis. The present evidence illustrates the potential superiority of steroids compared with local anesthetic at two year follow up based on average relief per procedure.

Human Immunodeficiency Virus (HIV) patients have an increased rate of chronic pain, particularly peripheral neuropathy. This disease burden causes considerable disability and negatively affects quality of life. Pain is undertreated and more complex to manage in these patients for a number of reasons, including complex anti-retroviral drug regimens, higher risks of side effects, and higher rates of comorbid psychiatric illness and substance abuse. Pain management must take these factors into account and use all available modalities, including nonopioid pain relievers, adjuvant medications, and psychosocial therapies in addition to opioid analgesics. Here we review recent recommendations regarding acute and chronic opioid treatment of pain and the treatment of opioid dependence in HIV-infected patients, and provide suggestions regarding aberrant behavior in pain treatment. ⋯ Pain management in HIV patients must take these factors into account and use all available modalities for treatment, including nonopioid analgesics, adjuvant medications, and psychosocial therapies. Opioid analgesics should be prescribed with caution in accordance with current guidelines and after careful risk assessment.

Low back pain after either post lumbar surgery syndrome or spinal stenosis in the absence of surgery is a vexing problem. Post lumbar surgery syndrome can occur in any age group, while low back and radicular pain from spinal stenosis is a disease of aging. As the population ages, the incidence of symptomatic spinal stenosis will increase. There are currently limited treatment options for either group. Further surgery is not uniformly effective in relieving pain after previous surgery. While therapies are being developed to treat pain due to spinal stenosis, no therapy other than adhesiolysis will treat pain due to scarring. Adhesiolysis was developed as a means of removing epidural scarring leading directly or indirectly to compression, inflammation, swelling, or a decreased nutritional supply of nerve roots. Adhesiolysis utilizes a number of modalities in the effort to break up epidural scarring, including the use of a wire-bound catheter for mechanical adhesiolysis, placement of the catheter in the ventro-lateral aspect of the epidural space at the site of the exiting nerve root, and the use of high volumes of injectate, including local anesthetics and saline, either hypertonic or isotonic, along with steroids. ⋯ In summary, there is fair evidence that percutaneous adhesiolysis is effective in relieving low back and/or leg pain due to post lumbar surgery syndrome or spinal stenosis.

In all recommended guidelines put forth for the treatment of cancer pain, opioids continue to be an important part of a physician's armamentarium. Though opioids are used regularly for cancer pain, there is a paucity of literature proving efficacy for long-term use. Cancer is no longer considered a "terminal disease"; 50% to 65% of patients survive for at least 2 years, and there are about 12 million cancer survivors in the United States. There is a concern about side effects, tolerance, abuse and addiction with long-term opioid use and a need to evaluate the effectiveness of opioids for cancer pain. ⋯ This systematic review of RCTs of opioids for cancer pain showed fair evidence for the efficacy of transdermal fentanyl and poor evidence for morphine, tramadol, oxycodone, methadone, and codeine.
