Herpes zoster (HZ; shingles) results from reactivation of varicella-zoster virus that has been dormant in the spinal and cranial sensory ganglia following primary infection with varicella (chickenpox), usually during childhood. In developed countries more than 95% of the adult population are seropositive for varicella-zoster virus and are therefore at risk of developing HZ. Reactivation can occ...

Pain associated with herpes zoster arise from the virul neuritis of the suffered trigeminal or spinal dorsal ganglion. Prolonged neuritis makes an irreversible nerve injury and continuous pain impulse develops a central sensitization. A post-herpetic neuralgia is thought to be a neuropathic pain due to the irreversible nerve injury and sensitization. It is important to treat herpetic pain compl...

Questions from patients about analgesic pharmacotherapy and responses from the authors are presented to help educate patients and make them more effective self-advocates. The topics addressed in this issue are postherpetic neuralgia and capsaicin and a discussion about symptoms, causes, and treatments is presented.

A case of herpes zoster ophthalmicus was followed, after a latent period of four weeks, by contralateral hemiparesis. An attempt is made to clarify the anatomical relationships involved in the pathogenesis of postherpetic cerebral complications. Detailed presentation of neuropathological findings in this case may provide evidence of vasculitis in the syndrome, with better understanding of the p...

PURPOSE Lidocaine patch 5% is recommended as a first-line therapy for postherpetic neuralgia pain in neuropathic pain guidelines. Postherpetic neuralgia can occur anywhere on the body but often follows acute herpes zoster occurring in trigeminal and brachial plexus dermatomes. An analysis was conducted to determine whether the anatomic location of lidocaine patch 5% is associated with variation...
