Contact Dermatitis
Inflammatory reaction of the skin after contact with an irritant or allergen
What causes contact dermatitis?
allergic or irritant with sensitivity to it
Irritant causes inflammation or contact dermatitis to
everyone
Allergen causes inflammation or contact dermatitis to
specific individual sensitive to it
Diaper Dermatitis Tx
- ointments?
Changing diaper ASAP
- Expose the bottom to air
Apply zincoxide,petroleum ointment, or Desitin
Wipes free of parabens
do not need to clean the cream off when changing bc you can layer over time

not ingested and cause respiratory distressed
- are safe when applied to your hand and bottom
Contact Dermatitis Tx
isolate the cause, limit exposure, and rinse area
Topical (small)
- Corticosteroids (Hydrocortisone)
- Lotions (Calamine)
PO (large like fabric)
- antihistamines (Benadryl)
- Steroids
Skin patch testing

Atopic dermatitis =
eczema
Eczema is
chronic relapsing inflammatory skin disorder
Atopic dermatitis results of/Associated with
of genetic factors, environmental agents (allergies or irritants)
Atopic dermatitis risk factors
family history of eczema,asthma, food allergies
(genetic link possible)
- auoimmune
Atopic dermatitis involvement (asymmetrical or symmetrical)
symmetrical on both location
Difference between contact dermatitis and atopic dermatitis?
Location and symmetry
CD = asymmetrical and anywhere
ad = SYMMETRICAL AND SPECIFIC
Atopic dermatitis S/S
severe pruritis (itching)
Atopic dermatitis Infant typical sites
face, inside the elbows, and behind the knees
Atopic dermatitis in older children’s typical sites
antecubital and popliteal area, neck, wrists and feet
Atopic dermatitis adolescents look like
Lichenification
Lichenification
leathery skin due to relapse over time
Atopic dermatitis Tx
hydrate (tepid or colloid)
- emollient application immediately after bath
relieve itching
reduce inflammation
prevent/control secondary infections
Tepid means
slightly cooler
Colloid
adding oatmeal or bran
Pattern to take care of eczema skin
tepid or colloid bath
Pat dry no rubbing
emollient skin immediately after (neurtogena, Aquaphor)
Relieve itching of Atopic dermatitis by
Colloid bath, cool wet compresses, topical corticosteroids, oral antihistamines
Reducing inflammation of Atopic dermatitis
Topical corticosteroids
Non-steroidal immunomodulator creams
How to prevent secondary infections of Atopic dermatitis
short/clean nails
soft cotton clothes not wool
antibiotics if an infection does occur
Seborrheic Dermatitis
sebum exposed
- chronic, recurrent, inflammatory reaction of skin
Seborrheic Dermatitis is most common in
early infancy and adolescents
cradle cap
Seborrheic Dermatitis locations
Eyelids (oily gloss)
External canal
Vasolabial folds
Inguinal region
Scalp - cradle cap
Seborrheic Dermatitis looks like
thick
yellow
scaly and oily patch
- possible itching (irritable)
Seborrheic Dermatitis Tx
Shampoo twice a day
- allow to sit for crusts to soften
- rinse
- fine tooth comb/soft brush to remove crusts
Impetigo is caused by
bacterial skin infection
Impetigo is caused by what bacterial contagions?
Staph aureus
Strep
What is a highly contagious bacterial infection most common on the face?
Impetigo
Impetigo is commonly seen on the
face, around mouth → spreads peripherally
Impetigo is spread by _______ contact
direct
Impetigo Primary at
site
bite
infection
If impetigo is itchy and caused by strep, it can lead to
glomerulonephritis
Impetigo Post-Op care
no daycare or school
HAND WASHING before and after touching infected areas,
separate child clothes and linens,
short and clean nails,
warm washing of cloths
gently remove the crust and debris
Impetigo Tx
Antibiotics (topical)
- Mupirocin (Bactro-van)
- Penicillin for systemic
Gentle cleansing of crusted areas
Don’t rupture the blisters – spread infection and increase secondary infection
Impetigo ruptures should not be ruptured because
spread infection and increase secondary infection
Impetigo is highly communicable for ___________ after antibiotics.
24 hours
Impetigo Nursing Interventions
Institute strict contact precautions
Strict hygiene practices – hand washing
Educate family and visitors on necessary precautions to prevent the spread of infection

Warm to touch
Lymphangitis “ streaking” - common
Possible systemic effects (fever, malaise)
Swollen regional lymph nodes
Is cellulitis contagious?
no, deeper layers of the skin
- caused by in open skin like IV
Cellulitis is what type of infection?
- and who can be affected?
opportunistic (not contagious)
- area od broken skin

Cellulitis Tx
Antibiotics
Oral - Choice

Varicella skin lesions are
(pruritic rash – itchy
papules and vesicles
Weeping
Crust over within 7 days (no longer contagious)
Varicella s/s systemic
fever
malaise
contagious 1-2 days before rash to crust
Varicella isolation
airborne and contact
- skin to skin or respiratory
Varicella Tx
- stop the itch (apply topical diphenhydramine cream
- acetaminophen (no aspirin = reye syndrome risk
- Immunocompromised (Acyclovir – antiviral)
- No longer infectious after lesions crust over
T1 Herpes Simplex once exposed to it then it is
always present
