Review Meta Analysis
Efficacy and adverse effects of buprenorphine in acute pain management: systematic review and meta-analysis of randomised controlled trials.
Buprenorphine appears to have a ceiling effect on respiratory depression, but not analgesia in healthy young patients. However, the efficacy and side-effects of buprenorphine in the setting of acute pain are poorly characterized. The aim of this study was to characterize the analgesic efficacy and adverse effects of buprenorphine compared with morphine in the acute pain setting. ⋯ There was only one secondary outcome with an overall significant difference; buprenorphine use was associated with significantly less pruritus (OR=0.31; 95% CI=0.12-0.84; I2=6%; P=0.02). Whilst a theoretical ceiling effect may exist with respect to buprenorphine and respiratory depression, in a clinical setting, it can still cause significant adverse effects on respiratory function. However, given that buprenorphine is an equally efficacious analgesic agent, it is a useful alternative opioid because of its ease of administration and reduced incidence of pruritus.

Renal colic is a common, acute presentation of urolithiasis that requires immediate pain relief. European Association of Urology guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs) as the preferred analgesia. However, the fear of NSAID adverse effects and the uncertainty about superior analgesic effect have maintained the practice of advocating intravenous opioids as the initial analgesia. ⋯ In kidney stone-related acute pain episodes in patients with adequate renal function, treatment with nonsteroidal anti-inflammatory drugs offers effective and most sustained pain relief, with fewer side effects, when compared with opioids or paracetamol.

Review Meta Analysis
Epidural steroids at closure post-microdiscectomy/laminectomy for reduction of post-operative analgesia: systematic review and meta-analysis.
This review assessed the efficacy of epidural steroid administration on the reduction of pain, hospital stay time, and use of opioid analgesics postoperatively. ⋯ Intraoperative or perioperative epidural administration of steroids offers significant benefits in terms of pain control, reduction in LOS, and use of postoperative opioid analgesia. Before steroids are routinely used by spinal surgeons, however, significantly more research is required. A particular emphasis should be placed on quality study protocols and data recording, to allow for more thorough analyses in the future.

Meta AnalysisOpioids combined with antidepressants or antiepileptic drugs for cancer pain: Systematic review and meta-analysis.
Combining antidepressant or antiepileptic drugs with opioids has resulted in increased pain relief when used for neuropathic pain in non-cancer conditions. However, evidence to support their effectiveness in cancer pain is lacking. ⋯ Combining opioid analgesia with gabapentinoids did not significantly improve pain relief in patients with tumour-related cancer pain compared with opioid monotherapy. Due to the heterogeneity of patient samples, benefit in patients with definite neuropathic cancer pain cannot be excluded. Clinicians should balance the small likelihood of benefit in patients with tumour-related cancer pain against the increased risk of adverse effects of combination therapy.

Review Meta Analysis
Association Between Opioid Use and Risk of Erectile Dysfunction: A Systematic Review and Meta-Analysis.
Opioid analgesics have been widely used to relieve chronic pain conditions; however, a connection between opioid analgesic administration and increased susceptibility to erectile dysfunction (ED) has been hypothesized. ⋯ Evidence from the included observational studies indicated that men with opioid use had a significantly increased risk of ED. Further randomized controlled trials are still needed to confirm this relation. Zhao S, Deng T, Luo L, et al.
