Chronic pain after lung resection: risk factors, neuropathic pain, and quality of life.
Chronic postsurgical pain (CPSP) can occur frequently after thoracic surgery. ⋯ More than one of three patients who underwent lung resection could develop CPSP, frequently showing neuropathic component. Female gender reported a higher CPSP and NP incidence. Moderate-to-severe acute postoperative pain occurrence and open surgery seem to be independent risk factors for CPSP. Chronic pain and NP have a negative impact on quality of life, decreasing the SF-36 scores of all domains.

To determine the risk factors for new neuropathic pain (NeP) after five years in healthy middle-aged and elderly volunteers. ⋯ This longitudinal cohort study identified five independent risk factors for development of new NeP after five years, with related factors of spinal inclination, sarcopenia, and sciatica. New NeP may be prevented by intervention or treatment of these factors at an early stage in relatively healthy middle-aged and elderly people.

ReviewManagement Strategies for Spinal Cord Injury Pain Updated for the Twenty-First Century.
Traumatic spinal cord injury (SCI) often results in several life-altering impairments, including paralysis, sensory loss, and neurogenic bowel/bladder dysfunction. Some of these SCI-related conditions can be accommodated with compensatory strategies. ⋯ In addition to the expected challenges in treating any chronic pain condition, treatment of SCI-related pain has the added difficulty of disruption of normal neural pathways that subserve pain transmission and attenuation. This article reviews selected treatment strategies for SCI-associated neuropathic pain.

ReviewCapsaicin 8% dermal patch in clinical practice: an expert opinion.
Neuropathic pain (NP) is caused by a lesion or disease of the somatosensory system, which can severely impact patients' quality of life. The current-approved treatments for NP comprise of both centrally acting agents and topical drugs, including capsaicin 8% dermal patches, which is approved for the treatment of peripheral NP. ⋯ Overall, the capsaicin 8% dermal patch is as effective in reducing pain intensity as other centrally active agents (i.e. pregabalin). Some studies have also reported fewer systemic side effects, a faster onset of action and superior treatment satisfaction compared with systemic agents. In our opinion, capsaicin 8% dermal patches also present additional advantages, such as a good systemic tolerability, the scarcity of adverse events, the possibility to combine it with other agents, and a good cost-effective profile. It is important to note that, as the mechanism of action of capsaicin 8% is the 'defunctionalization' of small afferent fibers through interaction with TRPV1 receptors, the peripheral expression of this receptor on nociceptor fibers, is crucial to predict patient's response to treatment.

With advances in peripheral nerve stimulation technology, there has been an emergence of new minimally invasive techniques to provide neurostimulation therapies for chronic pain. This technical note describes the utilization of ultrasonography for percutaneous placement of peripheral nerve stimulation leads at the sciatic, femoral, and lateral femoral cutaneous nerves. ⋯ The option of ultrasound-guided percutaneous technique for neurostimulation lead placement allows this treatment modality to be made available to more patients with chronic pain in specific nerve distributions.
