unit 6 Flashcards
Extrinsic causes of lesions
- Physical
- Chemical
- Allergic irritants
- Infectious agents
With Younger children
-skin layers separate easily inflammatory process = blisters
Intrinsic causes of lesions
- Infection
- Drug sensitization
- Allergies
History assessment when children have lesions includes
- Asthma or hay fever?
- When did the lesion first appear?
- Has it changed in appearance?
- New foods or medications?
- Contact with plants, pets, insects, chemicals?
Types of lesions
Erythema Ecchymosis Petechiae Distribution pattern Configuration/arrangement Configuration/arrangement Macule Papule Vesicle Bulla Nodule Pustule Cyst
Common Symptoms of lesions
- Pruritus (itching)
- Paresthesia (burning; prickling)
- Anesthesia (absence of sensation)
- Hypoesthesia (diminished sensation)
- Hyperesthesia (excessive sensation)
SKIN INFECTIONS include
- Bacterial
- Viral
- Fungal
Bacterial skin infections
- Bacterial Infections – (Table 24.1, p. 885)
- ——Impetigo (Nonbullous and bullous)
- ——Folliculitis (pimple), furnuncle (boil), carbuncle (multiple boils)
- ——Cellulitis—Streptococcus, Staphylococcus, Haemophilus influenzae
- ——Staphylococcal scaled skin syndrome

Viral skin infections
Table 15.4, pp. 469 – 473 Rubella (German Measles) Rubeola (Measles) Varicella zoster (Chickenpox) Exanthem Subitum (Roseola Infantum/sixth disease) Erythma infectiosum(fifths disease) Hand, foot, and mouth disease, or herpangina (coxsackie virus)
Fungal skin infections
- Tinea is a fungal disease of the skin occurring on any part of the body. -Tinea corporis
- Tinea capitis
- Tinea versicolor
- Tinea pedis
- Tinea cruris
- Diaper candidiasis
Diaper Dermatitis can come from (Fig. 24.10, p. 888)
- Inadequately rinsed cloth diapers
- Chemicals in disposable wipes
- Diarrheal stools
- Monitoring and changing diaper as soon as it becomes wet
Characteristics of Atopic Dermatitis- (Eczema) (Fig. 24.11, p. 890)
- Infantile: 2-6 mos, remission by age 3
- Childhood: 2-3 years of age
- Pre-teen and teenage: onset at 12 years; may continue lifelong
- Majority – family history (genetic predisposition)
- Symptoms improve with humidity and worsen during winter – dry heat
- Nursing goals: less itching; no secondary infection; skin hydration
Factors That May Trigger or Exacerbate Atopic Dermatitis include
- Irritants
- Contact and Airborne Irritants
- Microorganisms
- and Other Factors
Irritants that affect AD
- Soaps and detergents (use of hypoallergenic products are best)
- Disinfectants or cleaning products
- Contact with liquids such as citrus juice
- Perfumed products
- Fabrics with sharp fibers, such as wool or man-made fabrics
- Dust and dirt
Contact and Airborne Irritants of AD
- Dust mites
- Pet dander, hair, or saliva
- Human dander (dandruff)
- Molds
- Seasonal pollens
Microorganisms that affect AD
- Staph Aureus
- infections, such as URIs
- Mycologic, such as fungi and dermatophytes
Other Factors that may affect AD
- Temperature and climate (lack of humidity increases dryness of skin, sweating)
- Foods
- Psychological stressors
- Hormones
- Baths/Showers should be short and thoroughly pat dry
Medical management of AD
- Use of topical corticosteroids
- Emollients are used for both prevention and during therapy for active AD.
- Oral antihistamines are sometimes recommended for a limited period of time
- Clothing, linens made of either 100% cotton or a cotton blend with at least 80% cotton are recommended.
- Suggest families try products labeled hypoallergenic.
- Skin Care
a. Irritants should be washed off as soon as possible.
b. Addition of colloidal oatmeal to the water is soothing.
c. Immediately after medication application, smooth a thin layer of an emollient product over the skin d. Nails should be kept short, clean to minimize damage that may occur during scratching.
e. Children should be encouraged to try not to scratch
Poison Ivy, Oak, and Sumac (Fig. 24.12, p. 891) information
- Caused by the plant’s oil – urushiol – very potent as it penetrates through the epidermis and bonds with the dermal layer (initiates immune response)
- Even smoke from burning brush piles can produce a reaction
- Animal not affected but are carriers (fur and saliva)
- Lesions are blisters
- Healing and end of itching = 10-14 days
treatment of Poison Ivy, Oak, and Sumac
- Immediately wash with soap and warm water
- Avoid harsh soap and scrubbing
- Thoroughly launder all contact clothing – hot water
- Prevent scratching – risk for secondary infection
- Prevent scratching – risk for secondary infection
- Prevention – teach to recognize plants
- Meds: Benadryl, topical corticosteroids (limit use of calamine/caladryl in children)
Seborrheic Dermatitis- (Fig. 24.15, p. 893) facts
- Inflammatory reaction to the fungus Pityrosporum ovale and is worsened by peak sebaceous gland activity in infancy and adolescent (hormonal influence)
- Cradle cap – scalp lesions are yellow, greasy-appearing plagues
- Prevention – adequate scalp hygiene
- Mild shampoo to soften crusts, then rinse and comb to remove
- Antidandruff shampoos containing selenium sulfide, or ketoconazole.
Adolescent Acne (≥ 12 years) (Fig. 24.17, p. 896)
-Most common skin condition in adolescence involving the hair follicle and sebaceous
glands over face, neck, chest, and upper back
-Peak years: 16-17 in females and 17-18 in males
-Causes
—- Hormonal
—–Cosmetics
—–No association with dietary intake
—–Psychological factors (emotional stress)
