Fever for children over 2
101
Fever can be…..
infectious or non-infectious
How to assess fever?
- Duration and degree of fever
- Associated symptoms (n/v, diarrhea, lethargy…)
- Recent known exposure to illness
- PMH
- Prior abx, surgeries,
- Current medications
- Immunization history
At what temperature does a fever cause damage to body?
107.6F
Strategies for fever management
- Adequate hydration
- Not all fevers need to be treated
- Appropriate clothing, do not bundle
- Room temp 72
- Tepid water baths for temp over 104, stop if shivering occurs
Contact Dermatitis
- Acute or chronic inflammation resulting from hypersensitive reaction to an irritant or allergen
Types of Contact dermatitis
- Dry skin
- nickel
- Phytophotodermatitis
- plant oleoresins
- juvenile plantar dermatosis
- latex dermatitis
Dry skin dermatitis
very low humidity, excess soap use, inadequate rinsing of soap
Nickel dermatitis
– buttons, belts, jewelery, eyeglasses
Phyto photodermatitis
sun exposure following contact with limes, lemons, celery, carrots, parsnips or dill (blistered lesion)
Plant oleoresin dermatitis
poison ivy, oak or sumac – can be direct or indirect, oil may be inhaled and damage lungs
Juvenile plantar dermatitis
dryness, cracking, and erythema of weight-bearing surfaces of the feet, initially the big toes; it mimics tinea pedis, often found in children with atopic dermatitis
Common substances that cause dermatitis
- saliva
- urine, and feces
- baby wipes
- bubble bath
- agents that dry the skin
- adhesives
- diapers
- allergens
Physical exam findings
for dermatitis
- Localized rash with sharp borders,
- Severity depends on length of exposure
- Irritant reactions are immediate and allergic reactions are delayed
Management of contact dermatitis
- Burrow solution soaks or oatmeal baths and cool compresses with salt water applied for 20 minutes every 4-6 hours to soothe vesicular rashes
- Petrolatum or lanolin based emollients
- Topical corticosteroids used 2-3xday for 2-2 days
- Oral antihistamines for pruritis
- Resolution may take 2-3 weeks
Scabies
- Parasite that burrows into the skin and causes intense itching
- Highly contagious through close contact
Physical findings for scabies
- Characteristic lesions include curving S-shaped burrows, especially on webs of fingers and sides of hands, folds of wrists and armpits, forearms, elbows, belt line, buttocks, genitalia, or proximal half of foot and heel.
- Dozens of lesions on small children, older children have fewer lesions
Treatment for scabies
- Apply thin layer of scabicide to entire body excluding eyes
- Especially fingernails, the scalp, behind the ears, all folds and creases, and the feet and hands
- Repeat treatment after 7 days
- Permethrin cream – apply to whole body and rinse after 8-14 hours
- Family and friends should be treated
- Wash clothing in hot water, vacuum
- Seal non washable clothing in a bag for 1 week
Education for scabies
- Rash and itching can continue for 3 weeks after treatment
- Can return to school 24 hours after treatment
Chiggers
- The larvae of harvest mites secrete an irritating substance that cases the skin eruption characteristic of chigger bites. Chigger mites live on grain stems, shrubs, grass, and vines and attach to human or animals that pass by.
Symptoms of chiggers
Complaints of itching followed by dermatitis; history of playing or walking in grassy areas, parks, or other mite habitat near woods and water
Physical findings for chiggers
- Discrete, bright-red papules 1 to 2 mm in diameter that often have hemorrhagic puncta
- Lesions mainly seen on legs (sock area) and belt line but can be widespread
- Wheals, papules, or papulovesicles in sensitized individuals
- Bullae or purpuric lesions with secondary hypersensitivity reaction
- Intense pruritus reaching a peak on the second day and decreasing over the next 5 to 6 days, but can persist for months
- Possible secondary impetigo from scratching lesions
- May see the embedded chiggers
Treatment for chigger bites
- Cool compresses
- Topical corticosteroids (e.g., 1% hydrocortisone cream)
- Topical antipruritic agents, such as calamine lotion; avoid topical diphenhydramine
- Oral antihistamines (e.g., diphenhydramine) if topical corticosteroids do not provide relief
- Removal of embedded chiggers (can be withdrawn by covering the insect with alcohol, mineral oil, nail polish, or ointment)
- Colloidal oatmeal baths (clean tub thoroughly after bath to avoid fall risk from oil residue left behind)
- Treatment of secondary skin lesions as indicated
- Elimination of fleas by treating animals and cleaning carpets, bedding, upholstered furniture; avoid areas that are potentially infested with mosquitoes, fleas, or chiggers
- Insecticides should be used with caution
Pediculosis
- August to November is lice season
- Head lice not a health hazard, do not spread disease
Symptoms of pediculosis
- History of infestation friend/family
- Itching
- Dandruff
- Crawling sensation of the scalp
Physical exam findings for pediculosis
- Nits attached to the hair shaft and will grow out
- Commonly found back of neck, head, ears, eyelashes
- Occipital or cervical lymphadenopathy
- Treat head lice – rinse with shampoo in sink with warm (not hot) water
Body lice
- Excoriated macules
- Belt, collar, and underwear lines common
- Pinpoint macule where the louse has extracted blood
- Axillary, inguinal, regional lymphadenopathy present
Pubic lice
- Excoriation and small bluish macules and papules
Treatment for pediculosis
- Permethrin 1% (widespread resistance) – safe for children older than 1 month old
- Topical ivermectin
- Malathion lotion
Steps
* Apply pediculicide – permethrin
* Remove nits with comb
* Cleanse environment
* Return to school after permethrin treatment
Nevi
Most commonly vascular.
Vascular nevi are caused by a structural abnormality (malformations) or by an overgrowth of blood vessels (hemangiomas) and are flat, raised, or cavernous.
Salmon patch
light pink macule usually seen at back of neck, forehead or upper eyelids – fade with time
Pigmented nevi
present at birth or acquired during childhood. Includes dermal melanocytosis, cafe au lait spots, acquired melanocytes nevi, acanthuses nigricans
Dermal melanocytosis
Blue or slate gray irregular nevi. Benign, more common in dark skin. Usually fade over time.
Café au lait spots
tan to light brown macules, oval, irregular, increase in numbers with age,
Acquired melanocytic nevi
light to dark brown, flat or slightly raised usually found in sun exposed areas above the waist
Acanthosis nigricans
velvety brown rows of hyperpigmentation in irregular folds of skin, usually the neck and axilla; tags may also be present.
Not treatable. Associated with insulin resistance and internal tumor.
Hemangiomas
Manifest initially as a pale macule, a telangiectatic lesion, or a bright red nodular papule. After appearing, hemangiomas go through a proliferative phase during which they grow rapidly and form nodular compressible masses, ranging in size from a few millimeters to several centimeters. Occasionally they may cover an entire limb, resulting in asymmetric limb growth. Rapidly growing lesions may ulcerate. (treat with propranolol)
Atypical nevi
larger than aquired nevi, irregular, poorly defined borders and variable pigmentation
