What will you find on physical exam with Strabismus
cover/uncover exam- eye can drift
What is Bruckner’s test
Bruckner testing can be helpful in observing strabismus. When doing the Bruckner test, fundus reflex is one characteristic to pay close attention to. A patient with a strabismus may show an increased light reflex in the deviated eye. Using your occluder, occlude the non-deviated eye as if you were doing a unilateral cover test, and you may be able to observe a change in fundus reflex of the deviated eye. The reflex may change from a brighter white to a duller red. Why? The macula is usually the most heavily pigmented area of the retina; therefore, once the deviated eye takes up fixation upon unilateral occlusion, the reflex will assume a duller appearance
What is the diagnosis- loss of red light reflex in one eye
Retinal blastoma
Treatment for Strabismus
Glasses
Eye muscle exercises
ocular surgery
What is the most common infection of the middle respiratory tract?
Laryngotracheobrochitis - Croup

What causes the stridor?
Describe stridor
Croup
the walls of the subglottic airway are drawn together during INSPIRATION
what is the Patho behind Laryngotracheobrochitis
inflammation and edema of laryngotracheal airway
kids already have a smaller airway to being with
this will lead to increased airway resistance and increased work of breathing during INSPIRATION (Stridor)
Laryngotracheobrochitis is commonly seen in whom? what time of year?
6 months to 3 years
Peaks in the Fall early winter time
Key symptoms should make you think what diagnosis-
Stridor- inspratory, barky seal-like cough, hoarseness, increase work of breathing, retractions +/-
nasal flaring, often starts out like cold symptoms (or out of the blew no pre-warning symptoms)
Laryngotracheobrochitis- CROUP !

What is the treatment for mild Croup
mild- no stridor at rest
symptomatic - humid air, fever reduction, fluids, cool mist humidifier
ONE dose Dexamethasone 0.6mg/kg in office
What is the treatment for moderate-severe Croup
Stridor at rest & retractions
try keeping the child calm to minimize labored breathing
Dexamethasone 0.6mg/kg - oral, IV or IM
If severe = Racemic aerosolized epinephrine by nebulizer (q 20 min)
*observe for 3-4 hours and decided to admit or not
*monitor for rebound effect
* worsening as drug clears
-Humidifed air
- antipyretics, fluids
How often can you give Racemic Epinephrine with Croup

that is why its called Laryngotracheitis
What part of the lungs does Bronchiolitis effect?
