Pharyngitis: Inflammation of the pharynx and surrounding lymphoid tissue
Viral or bacterial (Group A beta hemolytic streptococci (GABHS)–serious complications including rheumatic fever and glomerular nephritis)

Viral Pharyngitis: Gradual onset
Sore throat – reaches peak on the 2nd or 3rd day)
Erythema and inflammation of pharynx and tonsils
Fever (usually low grade)

Pain vomiting, headache Cervical lymph nodes enlarged Usually last 3-4 days If strep treated with penicillin for 10 days or erythromycin if allergic to pen Noninfectious after 24 hours of penicillin treatment Acetaminophen, warm salt water gargles

Tonsillitis (general info): Inflammation and infection of the two palatine tonsils
May be viral or bacterial
Rare before 3

Tonsillectomy

Otitis Media (general info): One of the most common childhood illnesses
Refers to infection or blockage of the middle ear
Generally described as Acute OM (sudden onset with short duration) or OM with effusion (presence of fluid – effusion – behind the tympanic membrane
Etiology: bacterial - Streptococcus pneumoniae, H-influenzae
Viruses (RSV and influenza) and allergies often predispose them to infection
Peak incidence 6-12 months (onset within first year increases risk of recurrent disease

Otitis Media (risks): Day care
Use of pacifier after 6 months
Environmental smoke exposure
Bottle-feeding (putting child to bed with bottle, also causes tooth decay
Allergies/URI’s

S/S Acute OM: Bulging, opaque, red, non-mobile TM
Drainage (usually yellowish green, purulent, and foul smelling, indicates perforation of TM)

OM with effusion

S/S OM with effusion: Dull gray or yellow; retracted TM with decreased mobility; air bubbles may be visible through tympanic membrane
Tinnitus – popping sounds
Hearing loss, difficulty communicating

Varicella (Chicken pox) Transmission:: primary secretions of respiratory tract or skins lesions

Varicella (Chicken pox) S/S: Fever, malaise, anorexic 24-48 hours prior to rash
Macular rash – usually starts on trunk, scalp and then extremities (develops in crops over 3-4 days, goes from rash, to teardrop vesicles, pustular then dry and develop crust
Zoster (shingles) - found in primary infection of varicella where the varicella-zoster virus enters the sensory nerve and dorsal root ganglia and establishes an infection. Presents with pain and tenderness along involved nerve and surrounding skin for 2 weeks prior to rash

Varicella (Chicken pox) Complications: Secondary bacterial infection of lesions – staph & group A strep from scratching can result in impetigo
CNS complications –encephalitis, convulsions, coma

Removing nits – using find tooth nit comb
Preventing spread or recurrence – treat and /or wash all linens, has, combs and brushes
Cleaning of carpet, furniture

Transmitted by close personal contact with infected persons (scabies mite cannot survive more that 3 days away from human skin)
Major complication is impetigo from continued scratching

Scabies S/S: Intense puritus – worse at night, visible burrows, papules, vesicles, nodules more common on the wrist, finger webs, elbows, umbilicus, axillae, groin, and buttocks
May develop secondary infection

Scabies Tx: Topical Elimite or Kwell (because risk of neurotoxicity do not use Kwell with children

Dermatitis: Contact - Diaper Dermatitis
Atopic – eczema
Seborrheic – cradle cap
