This study reviews the available literature regarding the use of nerve blocks for the management of peripheral neuropathy. ⋯ Most discussions on the management of peripheral neuropathy do not include the use of nerve blocks. Nevertheless, the nerve block procedures discussed here can play an important role in the management of these conditions.

The objective of this article was to review the positive scientific data on antidepressants and opioids, which are largely confined to randomized controlled trials in two neuropathic pain conditions that have proved to be good models for clinical investigation. These two disorders are postherpetic neuralgia and painful diabetic neuropathy. ⋯ First-line therapy for neuropathic pain may be either an older generation antidepressant such as amitriptyline or nortriptyline or the anticonvulsant gabapentin. For refractory cases, chronic opioid therapy may be the only avenue of relief, and evidence is accumulating that this approach is safe if proper guidelines are observed.

Postherpetic neuralgia (PHN) is a chronic pain syndrome that is often refractory to treatment and can last for years, causing physical and social disability, psychological distress, and increased use of the healthcare system. In this paper we provide an update on recent developments in the treatment of PHN. We emphasise the results of recent studies that provide an evidence-based approach for treating PHN that was not available until very recently. ⋯ Based on these results, nortriptyline can now be considered the preferred antidepressant for the treatment of PHN, although desipramine may be used if the patient experiences unacceptable sedation from nortriptyline. The topical lidocaine patch, gabapentin and controlled release oxycodone all appear to be as effective as tricyclic antidepressants in the treatment of patients with PHN, and the results of these recent studies suggest that each of these treatments should be considered early in the course of treatment. Additional controlled trials are needed to compare the efficacy and tolerability of these 4 treatments- tricyclic antidepressants, gabapentin, the topical lidocaine patch and controlled release opioid analgesics--used singly and in various combinations in the treatment of patients with PHN.

This article describes herpes zoster (HZ), its cause, diagnosis, treatment, and associated complications. Postherpetic neuralgia (PHN), the most common complication of HZ, is the primary focus of the discussion. PHN is defined broadly as chronic pain that persists after the characteristic vesicular rash of HZ has resolved.

ReviewManagement of herpes zoster (shingles) and postherpetic neuralgia.
Herpes zoster (commonly referred to as "shingles") and postherpetic neuralgia result from reactivation of the varicella-zoster virus acquired during the primary varicella infection, or chickenpox. Whereas varicella is generally a disease of childhood, herpes zoster and post-herpetic neuralgia become more common with increasing age. Factors that decrease immune function, such as human immunodeficiency virus infection, chemotherapy, malignancies and chronic corticosteroid use, may also increase the risk of developing herpes zoster. ⋯ Patients with postherpetic neuralgia may require narcotics for adequate pain control. Tricyclic antidepressants or anticonvulsants, often given in low dosages, may help to control neuropathic pain. Capsaicin, lidocaine patches and nerve blocks can also be used in selected patients.
