To present a technique that better visualizes the needle during interlaminar cervical epidural steroid injection (ICESI) in patients where the lateral view is inadequate. ⋯ Grave complications have been associated with ICESI necessitating impeccable and systematic technique with substantial knowledge of anatomy. Although injection at lower levels is advocated for safety concerns, the needle during lateral view may be obscured by the shoulders in some patients. The "Swimmer's View" position may be attempted when lateral view is insufficient to visualize needle during ICESI.

This preliminary study assessed possible relationships between plasma and/or cerebrospinal fluid (CSF) concentrations of the pleiotropic cytokine, interleukin (IL)-6, the anti-inflammatory cytokine, IL-10, and levels of pain reported by patients receiving intrathecal (i.t.) opioids. ⋯ The significant inverse correlations observed between pain intensity and the plasma IL-6 and IL-10 concentrations in patients receiving longterm i.t. opioids for chronic pain management, suggests that these cytokines are worthy of further investigation as possible biomarkers of persistent pain.

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
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.
