Step assessment for foreign body in eye
visual acuity of both eyes
Snellen / pen light
Exam slit lamp
fluorescein stain - assess for corneal defects
eyelid eversion - remove foreign body with wet cotton swab if NOT embedded

Updated tetanus
Allergic rhinitis S/S
- Clear BILATERAL rhinorrhea
- nasal stuffiness
- allergic shiners - dark under eyes
- pale, boggy nasal mucosa

- sore throat/mouth upon waking
- palpable lymph nodes
- enlarged tonsils and adenoids –> leads to increased risk of otitis media
what would you treat a sinus infections with?
Amoxicillin or Augmentin
Same as ear infection
Pharm management for allergic rhinitis
***Always use localized agents before systemic!
- Saline nasal sprays - wash off offending particles prior to other nasal medications
- Nasal steroids - preferred agent (Fluticasone propionate- Flonase) or Budesonide
- Nasal antihistamine sprays - azelastine (can be combined with fluticasone)
- oral antihistamines (non sedating)
is sinusitis typically viral or bacterial?
Typically VIRAL — tx symptomatic only
what suggests bacterial sinusitis?
> 10 days, acute fever, s/s worsen after initial improvement (secondary infection)
Tx for bacterial sinusitis?
ABX
Amoxicillin/ Augmentin
Doxycycline, Levofloxacin or moxifloxacin if PCN allergy
***NO MACROLIDE —high resistance
No improvment after 3-7 days of ABX therapy, consider broader cover abx
-partial response consider additional 10-14 days of same or different abx
How do you demine who gets a rapid strep test?
Use Modified Centor Criteria –> point system based on symptoms
+1 for each : tonsillar exudate, tendery anterior chain adenopathy, fever, <15yr.
0 point : 15-45yr
-1 Point: >45yrs or cough
***cough almost always excludes streptococcus!
Most common pathogen for acute epiglottitis?
Haemophilus influenza type B (COP) Streptococcus pneumoniae (3p lecture)
patient comes in with marked edema of the supraglottic structures with difficulty swallowing. what should you suspect?
Epiglottitis — MEDICAL EMERGENCY
Signs of acute epiglottitis?
xray –> steeple sign/ thumb sign
inflammation and edema of supraglottic structures (epiglottis, aryepiglottic folds, arytenoids)
DO NOT attempt to visualize pharynx if suspected, can cause spasming and completely obstruct airway
What causes mononucleosis?
Epstein barr virus
Symptoms of infectious mononucleosis
i. Fatigue, malaise
ii. Headache, sensitivity to light
iii. Sore throat - becomes progressively worse
iv. enlarged tonsils w/ whitish-yellow covering
v. Lymph nodes in neck frequently enlarged/ painful
vi. Pink, measles-like rash can occur (more likely if pt given abx for throat infection)
vii. Enlarged spleen – no contact sports

What is conductive hearing loss?
inability of ossicles to conduct sound properly. Sounds are perceived by brain but are diminished but NOT distorted.
often caused by cerumen impaction, otitis media, foreign objects, TM perf,
