Randomized Controlled Trial
Efficacy of Duloxetine in Chronic Low Back Pain with a Neuropathic Component: A Randomized, Double-blind, Placebo-controlled Crossover Trial.
Among patients with chronic low back pain (CLBP), approximately 37% show signs of a neuropathic pain component (radicular pain). Treatment of this condition remains challenging. Therefore, the current study aimed to investigate the efficacy of duloxetine in the treatment of CLBP patients with neuropathic leg pain. ⋯ In this crossover study, duloxetine proved to be superior to placebo for the treatment of CLBP with a neuropathic leg pain.

Review Meta Analysis
A systematic review and meta-analysis of risk factors for postherpetic neuralgia.
Patients with herpes zoster can develop persistent pain after rash healing, a complication known as postherpetic neuralgia. By preventing zoster through vaccination, the risk of this common complication is reduced. We searched MEDLINE and Embase for studies assessing risk factors for postherpetic neuralgia, with a view to informing vaccination policy. ⋯ No evidence of higher postherpetic neuralgia risk was found with depression (n = 4) or cancer (n = 5). Our review confirms a number of clinical features of acute zoster are risk factors for postherpetic neuralgia. It has also identified a range of possible vaccine-targetable risk factors for postherpetic neuralgia; yet aside from age-associated risks, evidence regarding risk factors to inform zoster vaccination policy is currently limited.

Randomized Controlled Trial
Impact of topical 5% lidocaine-medicated plasters on sleep and quality of life in patients with postherpetic neuralgia.
To determine the impact of 5% lidocaine-medicated plasters on sleep, quality of life and pain in 265 patients with postherpetic neuralgia (PHN). ⋯ 5% lidocaine-medicated plasters provide benefits beyond pain relief for patients with postherpetic neuralgia.

Randomized Controlled Trial
Modulation of serum BDNF levels in postherpetic neuralgia following pulsed radiofrequency of intercostal nerve and pregabalin.
To study the modulation of serum BDNF levels following integrated multimodal intervention in postherpetic neuralgia (PHN). ⋯ Integrated multimodal therapy using minimally invasive pulsed radiofrequency and pregabalin in PHN was effective in early pain reduction with elevated serum BDNF levels.

Randomized Controlled TrialEffects of transcranial random noise stimulation (tRNS) on affect, pain and attention in multiple sclerosis.
Pain and cognitive impairment are frequent symptoms in patients with multiple sclerosis (MS). Neglecting experimental pain and paying attention to demanding tasks is reported to decrease the pain intensity. Little is known about the interaction between chronic neuropathic pain and attention disorders in MS. Recently, transcranial direct current stimulation (tDCS) was used to modulate various cognitive and motor symptoms in MS. We aimed to study the effects of transcranial random noise stimulation (tRNS), a form of transcranial electric stimulation, over the left dorsolateral prefrontal cortex (DLPFC) on attention and neuropathic pain in MS patients. ⋯ This study suggests the role of tRNS in pain modulation, which could have been more evident with longer stimulation protocols.
