We aimed to assess the diagnostic utility of the linguistically validated Japanese version of the Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS-J) as a screening tool for neuropathic pain in the clinical setting. ⋯ The LANSS-J is a valid screening tool for detecting neuropathic pain. Our results suggest that employing the original cutoff value provides high specificity, although a lower cutoff value of 10 or 11 (with its high specificity maintained) may be more beneficial when pain attributed to neuropathic mechanisms is suspected in Japanese patients.

Except for neurotrophin, no drug had an indication for postherpetic neuralgia (PHN) in Japan prior to pregabalin approval. This approval might have changed PHN treatment patterns. This study aimed to compare PHN treatment patterns and medical costs between patients who started treatment before and after pregabalin approval. ⋯ Excluding pregabalin acquisition costs, mean costs per patient for medications associated with PHN for 6 months from the first prescription were significantly lower after approval, ¥2882 vs ¥4185. Total medical costs were similar in both periods. Approval of pregabalin appeared to result in a treatment paradigm toward use of an approved therapy with demonstrated efficacy.

Review Meta Analysis
High Prevalence of Neuropathic Pain Component in Patients with Low Back Pain: Evidence from Meta-Analysis.
Low back pain (LBP) is a complex syndrome which includes a nociceptive (NcP) component, a neuropathic (NeP) component, or a mixture of components (mixed pain). The NeP component (NePC) in LBP is defined as the presence of NeP with or without an NcP. ⋯ Neuropathic pain, nociceptive pain, low back pain, symptom-based questionnaire, chronicity.

Randomized Controlled Trial
Aromatherapy Massage for Neuropathic Pain and Quality of Life in Diabetic Patients.
This study aimed to examine the effects of aromatherapy massage on neuropathic pain severity and quality of life (QoL) in patients suffering from painful diabetic neuropathy. ⋯ Aromatherapy massage is a well-tolerated, feasible, and safe nonpharmacological method that can be readily integrated into clinical settings by nursing staff. The essential oils rosemary, geranium, lavender, eucalyptus, and chamomile can be safely used by nurses in the clinical setting, if applicable. However, training and experience of nurses in aromatherapy massage is critical to achieving positive results.

Chronic pain after spinal cord injury (SCI) is a form of central neuropathic pain that is debilitating and often refractory to current pharmacological treatments. Neurostimulation pain therapies, such as epidural spinal cord stimulation, have only moderate success in reducing SCI pain. The pathogenesis of SCI pain may involve a state of central neuronal hyperexcitability, especially in the spinal cord dorsal horn, that develops after injury. ⋯ Our hypothesis can be readily tested in preclinical models of SCI pain by using a combination of in vivo electrophysiological (neuronal activity) and animal behavioral (pain response) approaches. Since ISMS electrodes stimulate the spinal structures directly, we expect that the effective stimulus intensity and energy consumption can be lower than that for epidural spinal cord stimulation. The proposed hypothesis may provide insights and rationales for developing a novel neurostimulation pain therapy by directly inhibiting the pain generators in the spinal cord, and ISMS may be an alternative strategy to treat SCI pain.
