Psoriasis

Psoriasis is a chronic noninfectious skin inflammation involving keratin synthesis that results in psoriatic patches, characterized by the eruption of circumscribed, discrete and confluent, reddish, silvery-scaled maculopapules. The lesions occur predominantly on the elbows, knees, scalp, and trunk.

Psoriasis most commonly begins between ages 15 and 35 and it can appear suddenly or slowly.

Type of Psoriasis
There are five main types of psoriasis.

1. Erythrodermic: The skin is redness and covers a large area.
2. Guttate: The skin appears small, pink-red spots.
3. Inverse: Skin redness and irritation occurs in the armpits, groin, and in between overlapping skin.
4. Plaque: Thick, red patches of skin are covered by flaky, silver-white scales. This is the most common type of psoriasis.
5. Pustular: White blisters are surrounded by red, irritated skin.

Symptoms:

• Pruritus
• Shedding, silvery, white scales on a raised, reddened, round plaque that mostly affects the scalp, knees, elbows, extensor surface of arms and legs, and sacral regions.
• A yellow discoloration, pitting, and a thickening of nails if they are affected.
• Joint inflammation with psoriatic arthritis.

Nursing Intervention:

• Administer daily soaks and tepid, wet compresses to the affected areas to remove scales.
• Assist the client to remove the scales during the soak.
• Occlusive dressing may be applied following application of corticosteroid to increase its effectiveness
• Plastic wrap or bags can be used as occlusive dressing.
• Instruct the client not to scratch the affected areas and to keep the skin lubricated to minimize itching
• Encourage client to wear light cotton clothing over affected areas.
• Instruct the client to be consistent regarding prescribed treatment and avoid over the counter medications.

LYME DISEASE

Lyme disease is a subacute inflammatory disorder caused by infection with Borrelia burgdorferi, a nonpyogenic spirochete transmitted by Ixodes scapularis (see image the end of this article), the deer tick bite, in the eastern U.S. and I. pacificus, the western black-legged tick, in the western U.S. Ticks live in wooded area and survive by attaching to a host. And tick nymphs are thought to be responsible for about 90% of transmission to human beings.

Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. Variations in clinical features or severity from one patient to another may be due to inborn variations in immune response, perhaps linked to the human lymphocytic antigen system. The specific symptoms are depend on stages.

First Stage : Early localized infection

• Symptoms occur several days to month following the bite.
• Flulike symptoms
• Small red pimple that becomes ring-shaped rash (see image on the end of this article), and it can be large or small

Second Stage: Early disseminated infection

• Symptoms occurs several week following the bite.
• Neurological complication
• Joint pain
• Cardiac complication

Third Stage: Late persistent infection

• Large joints becomes involved
• Arthritis progresses

CARE INTERVENTIONS:

1. Remove the tick with tweezers gently, wash skin with antiseptic.
2. Take a blood test for 4 – 6 weeks following a bite to detect the presence of lyme disease.
3. Antibiotics as prescribed if the lyme disease is confirmed.
4. Avoid area that contain ticks (wood area, grassy area) especially in summer.
5. Wear long-sleeved tops long pants, close shoes and hat while outside
6. It is recommended to spray the body with tick repellent before going outside.
