Symptoms And Treatments Of Shingles
Shingles is caused by the varicella-zoster virus which is associated with two distinct
diseases: childhood chickenpox (varicella) and shingles (zoster). After an attack of
chickenpox, the virus becomes dormant in sensory ganglia and may reactivate decades later
to produce zoster (shingles) or herpes zoster. Shingles is estimated to affect 2 in every
10 persons in their lifetime. This year, more than 500,000 people will develop shingles.
Fortunately, there is currently research being done to find a vaccine to prevent the
disease.
Shingles is an outbreak of a rash or blisters on the skin that may be associated with
severe pain. Early signs of shingles include burning or shooting pain and tingling or
itching generally located on one side of the body or face. The rash or blisters are
present anywhere from one to 14 days.
The origin of the term "shingles" remains a mystery even today. The word is derived
from the Latin term "cingulatus," meaning "to encircle or wrap around." The word might
refer to the pattern that shingles lesions often exhibit on the body, ringing the torso or
trunk. The medical-scientific term for shingles, herpes zoster, comes from the French and
Latin languages. Collectively, the two words mean "belt" or "girdle," again suggesting the
girdle-like pattern of skin eruptions that often arise on the trunk of a person during an
outbreak of shingles.
If shingles appears on the face, it can lead to complications in
hearing and vision. For instance, if shingles affects the eye, the
cornea can become infected and lead to temporary or permanent
blindness. Another complication of the virus is postherpetic neuralgia
(PHN), a condition where the pain from shingles persists for months,
sometimes years, after the shingles rash has healed. The rash and pain
usually go away within 3 to 5 weeks. Sometimes serious effects
including partial facial paralysis (usually temporary), ear damage, or
encephalitis (inflammation of the brain) may occur.
Although it is most common in people over age 50, anyone who has had chickenpox is at
risk for developing shingles. Shingles is also more common in people with weakened immune
systems from HIV infection, chemotherapy or radiation treatment, transplant operations and
stress.
Treatment for shingles includes antiviral drugs, steroids, antidepressants,
anticonvulsants, and topical agents. Calamine lotion, wet compresses, and frequent baths
can provide some measure of relief from skin eruptions. Precautions should be taken to
avoid irritating the eruptions or exposing the blisters to dirt or other foreign
substances that could lead to a skin infection. If the pain and discomfort are minor,
nonprescription pain relievers will help in many cases. The severity and duration of an
attack of shingles can be significantly reduced by immediate treatment with the antiviral
drugs acyclovir, valacyclovir or famcyclovir. These drugs may also help stave off the
painful aftereffects of shingles known as postherpetic neuralgia.
