Randomized Controlled Trial Comparative Study
Transforaminal versus parasagittal interlaminar epidural steroid injection in low back pain with radicular pain: a randomized, double-blind, active-control trial.
Epidural injections are the most common minimally invasive intervention used to manage low back pain with lumbosacral radicular pain. It can be delivered through either transforaminal (TF), interlaminar, or caudal approaches. The TF approach is considered more efficacious than the interlaminar approach probably because of ventral epidural spread. However, catastrophic complications reported with the TF approach have raised concerns regarding its use. These concerns regarding the safety of the TF approach lead to the search for a technically better route with lesser complications with drug delivery into the ventral epidural space. The parasagittal interlaminar (PIL) route is reported to have good ventral epidural spread. However, there is a paucity of literature comparing the effectiveness of PIL with TF. ⋯ Epidural injection delivered through the PIL approach is equivalent in achieving effective pain relief and functional improvement to the TF approach for the management of low back pain with lumbosacral radicular pain. The PIL approach can be considered a suitable alternative to the TF approach for its equivalent effectiveness, probable better safety profile, and technical ease.

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.

Randomized Controlled Trial
Transforaminal epidural injections in chronic lumbar disc herniation: a randomized, double-blind, active-control trial.
The estimated prevalence of lumbar radiculopathy has been described as 9.8 per 1,000 cases of low back pain. There are various surgical and nonsurgical modalities for treating lumbar disc herniation or radicular pain, including epidural injections. Epidural injection administration routes include transforaminal, interlaminar, and caudal approaches. The transforaminal approach requires the smallest volume to reach the primary site of pathology. Systematic reviews have yielded highly variable results, but a recent systematic review showed no significant difference among the 3 approaches. ⋯ Transforaminal 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 lack of superiority of steroids compared with local anesthetic at 2-year follow-up.

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.
