Randomized Controlled Trial Multicenter Study Comparative Study
Tapentadol prolonged release for managing moderate to severe, chronic malignant tumor-related pain.
Tapentadol prolonged release (PR) is effective and well tolerated for chronic osteoarthritis, low back, and diabetic peripheral neuropathic pain. ⋯ Results obtained during maintenance indicate that tapentadol PR (100-250 mg bid) is effective compared with placebo for managing moderate to severe chronic malignant tumor-related pain. Based on results obtained during titration, tapentadol PR provides comparable efficacy to that of morphine sulfate CR (40-100 mg bid), but is associated with better gastrointestinal tolerability.

Review Case Reports
Epidural steroid warning controversy still dogging FDA.
On April 23, 2014, the Food and Drug Administration (FDA) issued a letter of warning that injection of corticosteroids into the epidural space of the spine may result in rare, but serious adverse events, including "loss of vision, stroke, paralysis, and death." The advisory also advocated that patients should discuss the benefits and risks of epidural corticosteroid injections with their health care professionals, along with the benefits and risks associated with other possible treatments. In addition, the FDA stated that the effectiveness and safety of the corticosteroids for epidural use have not been established, and the FDA has not approved corticosteroids for such use. To raise awareness of the risks of epidural corticosteroid injections in the medical community, the FDA's Safe Use Initiative convened a panel of experts including pain management experts to help define the techniques for such injections with the aim of reducing preventable harm. ⋯ The results of this review show the efficacy of epidural injections, with or without steroids, in a multitude of spinal ailments utilizing caudal, cervical, thoracic, and lumbar interlaminar approaches as well as lumbar transforaminal epidural injections. The evidence also shows the superiority of steroids in managing lumbar disc herniation utilizing caudal and lumbar interlaminar approaches without any significant difference as compared to transforaminal approaches, either with local anesthetic alone or local anesthetic and steroids combined. In conclusion, the authors request that the FDA modify the warning based on the evidence.

The actions and regulations of the Food and Drug Administration (FDA) are crucial to the entire population of the U. S., specifically the public who take a multitude of drugs and providers who prescribe drugs and devices. Further, the FDA is relevant to investors, specifically in regards to biotech and pharmaceutical companies involved in developing new drugs. ⋯ In fact, the study submitted to the FDA showed a 50% pain improvement in only 48% of the patients in the treatment group and 21% of the patients in the placebo group at 85 day follow-up. This is a statistically significant result but its clinical relevance is unknown. The FDA approval decision occurring against the backdrop of the advisory panel recommendation is concerning and may result in serious consequences in the future.

Multicenter Study
Treatment of metastatic spinal lesions with a navigational bipolar radiofrequency ablation device: a multicenter retrospective study.
Spinal metastatic lesions are a common occurrence among oncology patients and contribute to significant morbidity. Treatment options have been limited in their effectiveness and scope to this point. ⋯ The STAR System is an RFA device that was safely and effectively used in the treatment of spine metastatic osseous lesions. This new device allows RFA treatment of previously untreatable lesions with resultant reduction in pain that was not controlled by systemic or radiation therapy.

Randomized Controlled Trial
Effect of thoracic epidural analgesia on pro-inflammatory cytokines in patients subjected to protective lung ventilation during Ivor Lewis esophagectomy.
Thoracic epidural analgesia (TEA) has a well-known effect on neurohormonal response. Attenuation of stress response by post-operative epidural analgesia has shown beneficial effects such as lower pain scores and less immunological alterations. ⋯ Our study concluded that TEA reduced the systemic pro-inflammatory response and provided optimal post-operative pain relief. Although there were no significant differences in adverse events, there was a trend towards improved outcome. Further clinical studies with larger numbers of patients are required.
