In a companion article, we synthesized current clinical and preclinical data to formulate hypotheses about the etiology of drug administration catheter-tip inflammatory masses. In this article, we communicate our recommendations for the detection, treatment, mitigation, and prevention of such masses. ⋯ Attentive follow-up and maintenance of an index of suspicion should permit timely diagnosis, minimally invasive treatment, and avoidance of neurological injury from catheter-tip inflammatory masses. Whenever it is feasible, positioning the catheter in the lumbar thecal sac and/or keeping the daily intrathecal opioid dose as low as possible for as long possible may mitigate the seriousness, and perhaps, reduce the incidence of such inflammatory masses.

To assess the effectiveness of the lidocaine patch 5% (Lidoderm), a targeted peripheral analgesic, in reducing pain intensity/interference with quality of life (QOL) among patients with postherpetic neuralgia (PHN). ⋯ Based on results of previous randomized, controlled trials and the current study, designed to gauge response in the clinical practice setting, the lidocaine patch 5% should be considered a first-line therapy, alone or in combination with other agents, for PHN due to its efficacy, safety, minimal systemic side effects and drug interactions, and ease of administration. Although the lidocaine patch 5% was equally effective in longstanding PHN, it would appear prudent to begin therapy as early in the course of PHN as possible.

This review will bring to the reader's attention recent developments in the literature regarding regional anesthesia in the outpatient setting, and allow the reader to evaluate whether these developments are appropriate for inclusion in clinical practice. ⋯ Recent publications suggest additional ways to add regional anesthesia techniques to outpatient surgical practice, particularly with the promise of extensive postoperative pain relief for the ambulatory surgery patient.

A recent article in the New Scientist argued that women were under-represented in clinical trials which, until now, had masked the finding that ibuprofen 400 mg was ineffective in women. ⋯ There is no clinically meaningful difference in the efficacy of ibuprofen 400 mg between men and women experiencing moderate to severe postoperative pain and women were well represented.

The herpes zoster rash occurs when a dormant varicella zoster virus reactivates in dorsal root and cranial nerve ganglia. Pain that persists in the region where this rash occurred after the cutaneous lesions have healed is termed postherpetic neuralgia (PHN). A wide variety of therapies has been used with varying degrees of success to prevent the occurrence of PHN and to reduce pain with established PHN. ⋯ Several classes of drugs are effective in attenuating the pain and hyperalgesia caused by PHN, but no single drug leads to the complete relief of symptoms. Additional research is needed to improve treatment strategies and define the role of invasive pain management techniques in cases where PHN is associated with intractable pain.
