*stop definitely by age 3
malocclusions
- Increased overjet

A
oral candidiasis (thrush)
- normal until age 2, after consider immunocompromised states
- Remember to examine the diaper area as the fungus is swallowed and then excreted in the stool and often the infant has a candidial diaper dermatitis as well, which will also need treatment.
DX: clinical or KOB smear: budding yeast/pseudohyphae
Tx:
- vNystatin suspension orally for up to 4 weeks.
- Clean bottle nipples and pacifiers in the dishwasher cycle.
- Breastfeeding moms should apply a small amount of the Nystatin suspension to their nipples to prevent re-infection to the infant
- If treatment fails, consider oral Diflucan for 7 days.
5
Q

A
herpangina (caused by cocksackie virus)

Tx of acute angle-closure glaucoma
*Ophtho emergency
2 steps: first lower IOP (acetazolamide, BB, mannitol), then open the angle (cholinergics)
1. acetazolamide (decrease aqueous humor production and therefore decreases pressure)
2. Topical BB (timolol) reduces IOP pressure w.o affecting visual acuity
3. Miotics/cholinergics (pilocarpine, carbachol)
*Peripheral iridotomy definitive treatment*
**AVOID: anticholinergics, sympathomimetics
101
- Slow gradual BILATERAL PAINLESS peripheral vision loss (tunnel vision)
- Cupping of optic discs, notching of the disc rim
Chronic (open angle) glaucoma
TX:
1. prostaglandin analogs 1st line (Latanoprost- greater reduction in IOP),
2. laser therapy
102
What is amaurosis fagux

Ramsay-Hunt Syndrome
TX: oral corticosteroids, antiviral meds, and pain meds.

113
- acute, sudden monoocular vision loss*
| - funduscopy: extensive retinal hemorhages ("blood and thunder" appearance
central retinal vein occlusion (CRVO)
114
- acute sudden monoocular vision loss often preceded by amaurosis fugax
- funduscopy: pale retina with cherry red macula, "box car" appearance
central retinal artery occlusion (CRAO)
