To systematically review the evidence for duloxetine in the management of painful diabetic neuropathy (PDN). ⋯ Duloxetine has a beneficial effect over placebo. Nevertheless, the evidence of superiority of duloxetine over pregabalin and amitriptyline should be explored further as there was only 1 trial for each category. Provided majority of the PDN patients share cardiovascular complications, use of duloxetine will be a good option for treating pain associated with PDN over amitriptyline. Future randomized controlled trials should be designed keeping this in mind.

Randomized Controlled Trial
Efficacy of Pregabalin in the Treatment of Prediabetic Neuropathic Pain.
We report the results of a pilot, enrichment-design, placebo-controlled crossover trial of pregabalin for the treatment of prediabetic small-fiber neuropathic pain. ⋯ This pilot study showed improvement of prediabetic neuropathic pain. Participants with higher pain scores at baseline had higher UENS scores and a lower IENFD. Limitations of the study include the small number of participants and the carry-over effect.

Activated Glia Increased the Level of Proinflammatory Cytokines in a Resiniferatoxin-Induced Neuropathic Pain Rat Model.
Administration of resiniferatoxin (RTX) can mimic the clinical symptoms of postherpetic neuralgia. However, it is unclear whether activated glia contribute to the pathogenesis of RTX-induced neuropathic pain; furthermore, the relationship between p38, N-methyl-D-aspartate receptor type 2B (NR2B) as well as proinflammatory cytokines and activated glia remains unknown. ⋯ Activated glia participate in the pathogenesis of RTX-induced neuropathic pain and are likely to be the source of proinflammatory cytokines. Inhibition of glia contributes to an analgesic effect. These findings provide a novel strategy for the treatment of postherpetic neuralgia.

Limited research exists to support the extrapolation of the analgesic efficacy of pregabalin from one neuropathic pain condition to another. This retrospective analysis evaluated similarities in the efficacy of pregabalin for treating neuropathic pain associated with post-herpetic neuralgia (PHN), diabetic peripheral neuropathy (DPN), and spinal cord injury (SCI) in a Japanese population, as a basis for considering the extrapolation of these data to other neuropathic pain conditions. ⋯ NCT00394901, NCT00553475, NCT00407745, NCT00424372, NCT00553280, NCT01202227.

Malignant pleural mesothelioma (MPM) is associated with severe pain. The underlying neurobiology of this is complex. The primary aim of this study was to characterize pain in MPM. ⋯ Pain in mesothelioma varies among patients and may have neuropathic components. An adequate pain assessment is necessary to guide the clinician in the appropriate choice of analgesics.
