Y1 - 2016 N1 - T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Postherpetic neuralgia (PHN) is a common pain syndrome that can transpire after an episode of herpes zoster (HZ). HZ, also known as shingles, is the reactivation of latent varicella zoster virus (VZV) that remains in the dorsal root ganglion. The virus typically reactivates years after the primary infection. It is clinically defined as a dermatomal prodrome of severe pain followed by the development of cutaneous lesions. The lesions involved are grouped vesicles that are in various stages of evolution with erythematous bases spread within a sensory dermatome. In order to understand how to treat PHN it is important to know the incidence, epidemiology, and pathophysiology of HZ.
