A
Bacterial conjunctivitis
Blepharitis
Hordeolum
9
Q

Q
What is a chalazion?
A
A chalazion is a chronic lipogranulomatous lesion affecting the upper or lower eyelid, caused by blockage of Meibomian gland duct(s) with retention and stagnation of secretion.
May occur spontaneously or follow an acute hordeolum (internal)
18
Q

27
Diagnosing a FB in eye - what do we need to check? When might referral be necessary?
Clinical dx
-Fluorescein to assess for corneal abrasion due to foreign body
-If concerned about corneal abrasion or injury was high speed (i.e., grinding metal), refer to opto/ optho (requires dilated exam, slit lamp exam)
28
Tx of FB in eye
- “if a corneal foreign body is detected, an attempt can be made to remove by irrigation after instillation of topical anesthetic; this is particularly helpful if multiple foreign bodies, i.e., sand” (up to date)
-Can then attempt to remove with sterile swab using direct visualization
-If unable to remove, refer to optometry/ ophthalmology for removal under magnification
-Treat corneal abrasion if present: topical antibiotic (drop or ointment, cover for pseudomonas if organic material or contact lens), +/- artificial tears; most abrasions clear spontaneously within 24 hours
29
Why don't we give everyone with a sore eye after an FB typical anesthetics to take home?
-Note: topical analgesics only for facilitating eye exam, NEVER for tx (risk of corneal melt or infection)
30
S&S of a corneal abrasion
Pain, redness, tearing, photophobia, FB sensation
De-epithelialized area stains with fluorescein dye
Pain relieved with topical anesthetic
31
Complications of a corneal abrasion
infection, ulceration, recurrent erosion, secondary iritis
32
Treatment of corneal abrasion
Topical antibiotic (drops or ointment) to prevent superinfection, abrasion from organic material should be covered against Pseudomonas
Pain relief:
Consider topical NSAIDs (caution due to risk of corneal melt with prolonged use). Can also give oral NSAIDs for mild to moderate pain.
Cycloplegic (relieves pain and photophobia by paralyzing ciliary muscle) - only in case of large abrasions (>50% of cornea) according to UptoDate
Pressure patch not recommended for small abrasions or contact wearers d/t infection risk & delayed healing (may help decrease pain in large abrasions)
33
How quickly does a corneal abrasion usually heal
Small abrasions will heal overnigtht. Most abrasions clear spontaneously within 24-48 h – just need to not rub it!

79
What is acute OM?
Infection of the middle ear= ossicles (malleus, incus, stapes)
80
Patho of AOM
Usually begins as inflammatory process following viral URTI involving nose/ nasopharynx/ eustachian tube and middle ear mucosa.
Edema caused by inflammatory process obstructs middle ear, leading to decrease in ventilation.
This leads to increased negative pressure from ear which acts as irritant, increasing exudate from middle ear, build of up mucosal secretions, allowing for bacterial/ viral colonization. They grow and can result in purulence
81
What symptoms form the triad of AOM?
Olagia
Fever (especially in younger children...2/3 present with low grade fever)
Conductive hearing loss

Rare: tinnitus, vertigo, facial nerve paralysis
83
When do we treat with abx in acute otitis media?
if <6 mo or moderate-severe illness
(fever >39, bilateral AOM, bulging TM, systemic features, vomiting, or severe local signs (perforation with purulent discharge)
signs of a perforated TM should always be treated with antimicrobial therapy (most commonly topical
Ciprodex) and examined for complications
84
First line abx in AOm?
High dose Amoxicillin BID x 5 days (10d if <2 years, perforated TM, or recurrent AOM)
85
Are most people with AOM treated with abx? What is the standard treatment approach?
Watchful waiting for 48- 72 hours (if previously healthy)
* High spontaneous recovery rate (80-90%)
* Does not affect incidence of severe complications (mastoiditis, meningitis)
* Provide conditional prescription (start if symptoms do not improve after 2-3 days)
* Need to be sure patient/ parent is reliable for follow up.
* Can give acetaminophen/ ibuprofen to treat earache
* Seek immediate reassessment if symptoms worse or new symptoms appear (rash, drowsy, vomiting, difficulty breathing)

7 days
For bacterial, will see persistent symptoms or worsening symptoms >5 d or presence of purulence for 3-4 d with high fever (>39°C)
91
What are the criteria for diagnosing acute bacteria rhinosinusitis (ABRS)?
Think PODS!
(there's a great flowsheet in Toronto notes that I've put into our shared notes)
For diagnosis of ABRS, patient must have
1. nasal obstruction or nasal purulence/discoloured postnasal
discharge and
2. at least one other PODS symptom
P Facial Pain/pressure/fullness
O Nasal Obstruction
D Nasal purulence/discoloured postnasal Discharge

**In other words, need either O or D and at least 2 major symptoms overall (P, O, D, or S)
92
If it has lasted less than 7 days, we assume the sinusitis is caused by what?
Virus (usually peaks by day 3 and resolves by day 5-7 days)
Then if symptoms worsen, persist, or change, consider bacterial cause (and follow acute bacterial algorithm)
93
What sinuses are most often affected in sinusitis?
Maxillary
94

96
Treatment of sinusitis?
for symptom relief: oral analgesics (acetaminophen, NSAIDs), nasal saline rinse, short-term use of
topical/ or oral decongestants
* mild to moderate acute bacterial sinusitis: intranasal corticosteroids
severe acute bacterial sinusitis: antibiotics and intranasal corticosteroids
frst-line antibiotic is amoxicillin, and second line is amoxicillin-clavulanic acid or a
fuoroquinolone
97

102
How common is viral vs bacterial causes of pharyngitis in adults vs kids
Adults - ~90% viral, 5-15% of cases caused by GABHS
Kids
- up to 50% GABHS
◆ most prevalent between 5-17 y/o
103
In bacterial causes of sore throat, do you expect a cough?
No - absence of cough is evidence for bacterial cause (+1 on centor)
104
What other signs and symptoms give a +1 score on the modified centor criteria (indicating more likely is bacterial)
- absent cough
- history fever >38
- tonsillar exudate
- swollen anterior lymph nodes
- age 5-14 yrs
105
You can a score of -1, 0, 1 on the centor criteria. What do you do?
No further testing or abx
106
You can a centor score of 2 or 3. What do you do?
Perform culture of rapid test. Treat only if test is POS.
107
Centor score 4 or more, what do you do?
Start abx if patient situation warrants (high fever or clinically unwell)
If culture or rapid strep test performed and negative, discontinue abx.
108
How does indication for taking throat culture differ in children from adults?
For suspected Strep throat in children, if they have a negative Rapid Strep Test, guideline still recommends a throat culture to confirm as children are at a higher risk of developing rheumatic fever
A negative antigen test for strep A is enough in adults (test is much more specific and sensitive for adults than children)
109
Treatment with abx may be indicated for treatement of pharyngitis regardless of centor score in what circumstances?
- household contact with strep infection
- community endemic
- client hx of rheumatic fever, valvular heart disease, or immunosuppression
- population in which rheumatic fever remains a problem
(I assume we still take culture for each of these situations and they would need to be presenting with symptoms)
110
Primary purpose of treatment of strep infection is?
To prevent acute rhematic fever
111
How long is abx treatment for strep infection?
10 days
112
First line tx for strep A infection in adults?
Penecillin V or amoxicillin
113
T/F Lots of people carry group A strep asymptomatically. Do you care about this?
Yes 20% of population.
Only need to be identified and treated if there is family hx of rhematic fever, outbreak of rheumatic fever, outbreak of pharyngitis in closed community, or repeat trasmission within families
114
You patient presents with a sore throat. They are also having a very hard time swallowing, are drooling and speak with a "hot potato" voice. What are you thinking?
Consider epiglottitis, peritonsillar abscess, retropharyngeal abscess until proven otherwise
- may also present with stridor
115
Topical decongestants should not be used for > ____ days to avoid _______
3-4 days
Rebound congestion
116
If you prescribe amoxicillin to a person who has mono, what happens?
Develop rash
117
Prolonged oral decongestant use can cause what?
Elevated BP
118
T/F Mild erythema around the TM is always a sign of infection
No - Mild erythema around the tympanic membrane without ear pain, bulge & pus--- can be caused by many reasons---crying, URI, fever, irritation etc.
If there is ear pain with a red, bulging TM and pus behind it, most likely it is an infection
119
Your patient is confirmed to have strep throat but they are allergic to penicillins. What do you do?
- need to assess severity of allergy
- If not severe, can give any cephalosporins
- If severe, avoid 1st gen cephalosporins (cefazolin, cephalexin, cefadroxil, and ceforozil) but can give 2nd or 3rd gen cephalosporins
120
How long are bacterial/viral conjunctivitis contagious? How long to advise to restrict contact after treatment initiated?
High contagious for 48-72 hours
Restrict contact for 24-28 hours after treatment initiated
121
