PSORIASIS
RATHEESH R L

2.
• Psoriasis is a chronic, non infectious, recurrent
erythematous inflammatory disorder involving
the keratin synthesis.
• Psoriasis is a persistent, long-lasting (chronic)
disease.
• Psoriasis causes cells to build up rapidly on the
surface of the skin.

3.
CAUSE
• The cause of psoriasis isn't fully known, but
it's thought to be related to an immune
system problem with cells in the body.

4.
Risk factors
Anyone can develop psoriasis, but these factors
can increase your risk of developing the disease:
• Family history.
– Perhaps the most significant risk factor for
psoriasis is having a family history of the disease.
– Having one parent with psoriasis increases risk of
getting the disease, and having two parents with
psoriasis increases risk even more.

5.
• Viral and bacterial infections.
– People with HIV are more likely to develop
psoriasis than people with healthy immune
systems.
– Children and young adults with recurring
infections, particularly strep throat, also may be at
increased risk.

6.
• Stress.
– Because stress can impact the immune system,
high stress levels may increase the risk of
psoriasis.
• Obesity.
– Excess weight increases the risk of psoriasis.

7.
• Smoking.
– Smoking tobacco not only increases risk of
psoriasis but also may increase the severity of the
disease.

PATHOPHYSIOLOGY
Normally keratinocytes migrate from the basal cells
to stratum corneum within 14 days.
In this disease the keratinocytes travel from the
basal cells to stratum corneum within 4-7 days and
immature growth of keratinocytes will occur and
also leads production of lesions and erythema.
Inflammation and plaque formation

CLINICAL FEATURES
• Red patches of skin covered with silvery scales
• Small scaling spots (commonly seen in
children)
• Dry, cracked skin that may bleed
• Itching and burning
• Thickened nails
• Swollen and stiff joints
• Oozing of lesions

10.
DIAGNOSIS
• History collection
• Physical examination
• Skin biopsy
• USG is performed to identify the changes in
stratum corneum

11.
MANAGEMENT
• Topical corticosteroids.
– These powerful anti-inflammatory drugs are the
most frequently prescribed medications for
treating mild to moderate psoriasis.
– Eg: hydrocortisone and methyl prednisolone

12.
• Vitamin D analogues.
– These synthetic forms of vitamin D slow down the
growth of skin cells.
– Calcipotriene (Dovonex) is a prescription cream or
solution containing a vitamin D analogue that may
be used alone to treat mild to moderate psoriasis

13.
• UV therapy:
– It is used to decrease the growth rate of cells, its
given three times in a day.

14.
• Photo chemotherapy
– In photo-chemotherapy a light activated medicine
( methoxsalen) is used, it inhibits the DNA
synthesis and decreases hyperkeratosis.

15.
Lifestyle and home remedies
• Take daily baths.
• Use moisturizer.
• Expose your skin to small amounts of sunlight.
• Avoid smoking
• Avoid drinking alcohol.

16.
NURSING MANAGEMENT
• Complete assessment of the skin,
• Provide skin care
• Advice the patient to not scratch or pull the
scales
• Provide warm water for bathing and instruct
avoid hot water
• Instruct the patient to dry the skin by blotting
with towel instead of rubbing with towel

17.
• Lubricate the skin with coconut oils it gives
comfort from the sores.
• Apply prescribed medicines on correct time
and the medicine should be keep away from
the eyes and mucous membrane as it produce
discofort.
