Condition Index Flashcards
Psoriasis
Psoriasis is a skin disease that causes a rash with itchy, scaly patches, most commonly on the knees, elbows, trunk and scalp. Psoriasis is a common, long-term (chronic) disease with no cure.
Symptoms:
- A patchy rash that varies widely in how it looks
from person to person, ranging from spots of
dandruff-like scaling to major eruptions over
much of the body - Rashes that vary in color, tending to be shades of
purple with gray scale on brown or Black skin and
pink or red with silver scale on white skin - Small scaling spots (commonly seen in children)
- Dry, cracked skin that may bleed
- Itching, burning or soreness
- Cyclic rashes that flare for a few weeks or months
and then subside
Stevens-Johnson syndrome
Stevens-Johnson syndrome (SJS) is a rare, serious disorder of the skin and mucous membranes. It’s usually a reaction to medication that starts with flu-like symptoms, followed by a painful rash that spreads and blisters. Then the top layer of affected skin dies, sheds and begins to heal after several days.
Symptoms (1-3 days prior):
- Fever
- A sore mouth and throat
- Fatigue
- Burning eyes
As the condition develops, other symptoms include:
- Unexplained widespread skin pain
- A red or purple rash that spreads
- Blisters on your skin and the mucous
membranes of the mouth, nose, eyes and genitals - Shedding of skin within days after blisters form
Toxic epidermal necrolysis (TEN)
Toxic epidermal necrolysis (TEN) is a rare, life-threatening skin reaction, usually caused by a medication. It’s a severe form of Stevens-Johnson syndrome (SJS). In people with SJS, TEN is diagnosed when more than 30% of the skin surface is affected and the moist linings of the body (mucous membranes) have extensive damage.
Symptoms:
- Widespread skin pain
- A spreading rash covering more than 30% of the
body - Blisters and large areas of peeling skin
- Sores, swelling and crusting on the mucous -
membranes, including the mouth, eyes and
vagina
