This session will introduce the general structure and function of the biological macromolecules: lipids, carbohydrates, and nucleic acids. Learning Objectives. 1  To understand the general structure and properties of lipids and phospholipids and their function in the cell.
Postherpetic neuralgia is a nerve pain due to damage caused by the varicella zoster virus. Typically, the neuralgia is confined to a dermatomic area of the skin, and follows an outbreak of herpes zoster (commonly known as shingles) in that same dermatomic area.
Some patients develop postherpetic neuralgia (PHN), in which the localized pain of shingles remains even after the rash is gone. As many as 15% of people with shingles develop postherpetic neuralgia; most of these cases occur in people over 50 years of age.
