Randomized Controlled Trial
NGX-4010, a high-concentration capsaicin patch, for the treatment of postherpetic neuralgia: a randomized, double-blind, controlled study with an open-label extension.
To assess the efficacy, tolerability, and safety of NGX-4010, a high-concentration capsaicin dermal patch (capsaicin 640 microg/cm(2), 8%) in patients with postherpetic neuralgia (PHN). ⋯ NGX-4010 is a promising topical treatment for PHN patients, which appears to be tolerable, generally safe, and effective.

Effects of intravenous prostaglandin E1 on pain and body temperature in patients with post-herpetic neuralgia.
Bathing, heating, or sympathetic blockade often alleviates pain due to post-herpetic neuralgia (PHN), suggesting that blood flow may affect PHN pain. Here, we examined the effect of prostaglandin E1 (PGE), which improves blood circulation, on pain and body temperature in patients with PHN. ⋯ Intravenous infusion of PGE produces analgesia associated with elevation of skin temperature in patients with PHN.

Randomized Controlled Trial
Safety and Efficacy of Dietary Agmatine Sulfate in Lumbar Disc-associated Radiculopathy. An Open-label, Dose-escalating Study Followed by a Randomized, Double-blind, Placebo-controlled Trial.
Objective. Agmatine, decarboxylated arginine, was shown in preclinical studies to exert efficacious neuroprotection by interacting with multiple molecular targets. This study was designed to ascertain safety and efficacy of dietary agmatine sulfate in herniated lumbar disc-associated radiculopathy. ⋯ Dietary agmatine sulfate is safe and efficacious treatment for alleviating pain and improving quality of life in lumbar disc-associated radiculopathy. Study Registration. ClinicalTrials.gov Protocol Registration System Identifier: NCT00405041.

Randomized Controlled Trial Comparative Study
Comparison of cutaneous anesthetic effect of 8% lidocaine spray with lidocaine patch using current perception threshold test.
A lidocaine patch is often used for topical anesthesia prior to venipuncture, but needs to be applied for several hours before the puncture, and the site is fixed. A metered-dose lidocaine pump spray could be used to produce cutaneous topical anesthesia. In this study, we compared the anesthesia between the spray and the patch. ⋯ Similar to the lidocaine patch, the lidocaine spray produces cutaneous weak anesthesia at 30 minutes after treatment. The spray seems to produce local anesthesia faster than the patch.

Randomized Controlled Trial Comparative Study
Comparing the psychometric properties of the Checklist of Nonverbal Pain Behaviors (CNPI) and the Pain Assessment in Advanced Dementia (PAIN-AD) instruments.
To examine and compare the psychometric properties of two common observational pain assessment tools used in persons with dementia. ⋯ Despite earlier studies supporting the reliability and validity of the CNPI and the PAINAD, findings from the current study indicate that these measures warrant further study with clinical users, should be used cautiously both in research and clinical settings and only as part of a comprehensive approach to pain assessment.
