25
Acute sinusitis - most accurate and best initial test
best initial --> CT | most accurate --> sinus aspiration for culture
26
Acute sinusitis - treatment
same as otitis media (amoxicillin) PLUS inhaled steroids
27
Acute sinusitis - use amoxicillin and clavulanate if
1. fever and pain 2. persistent symptoms despite 7 days of decongestants 3. purulent nasal discharge
28
chronic rhinosinusitis - treatment
nasal saline irrigation and nasal steroid therapy spray
29
Strep pharyngitis - clinical manifestations
1. pain/sore throat 2. exudate 3. adenopathy 4. NO COUGH/HOARNSESS
30
Strep pharyngitis - best initial test
Rapid strep test
31
Strep pharyngitis - most accurate
culture
32
Negative Rapid strep test in adults - next step
Nothing (very sensitive in adults)
33
positive Rapid strep test - next step
culture (the have the same specificity) but need to assess the risk for rheumatic fever or glomerulonephritis
34
strep pharyngitis - treatment
penicillin or amoxicillin
35
strep pharyngitis - treatment in penicillin allergy
azithromycin or clarithromycin | if allergy is just a rash use cephalexin
36
Influenza - clinical manifestation
1. arthralgia 2. myalgia 3. cough 4. headache 5. fever 6. sore throat 7. feeling of tiredness
37
Influenza - diagnosis
clinical --> if is in unlclear --> viral rapid antigen detection
38
Influenza - treatment names (and mechanism of action)
1. oseltamivir 2. zanamivir 3. baloxavir 4. peramivir Neuraminidase inhibitors
39
Influenza - why peramivir differs
It is IV
40
Influenza - treatment - when to give the drugs
if first 48 h
41
influenza - other than drugs
7 days isolation
42
Influenza - medications ONLY FOR INFL A
amantadine + rimantadine
43
influenza vaccine - indications
in general population at any age strongest: COPD, CHF, dialysis, steroid use, health care workers, older than 50
44
live vs inactivated vaccine for flu
- live is administrated by inhalation | - live only if younger than 50 without medical conditions
45

47
allergic rhinitis may be associated with the development of
asthma
48
allergic rhinitis - treatment (only names)
1. avoidance of the allergen 2. drugs: steroids, antihistamines, cromolyn, ipratropium bromide, leukotriene inhibitors, nasal saline spray and wash 3. immunotherapy
49
allergic rhinitis - avoidance of allergens
1. close windows and stay in airconditioned rooms to avoid pollen 2. avoid pets if there is an allergy to animal dander 3. cover mattresses and pillows with mite and dust - proof casings
50
allergic rhinitis - drugs
intranasal steroids, anihistamines (loratadine etc), intranasal antihistamines (azelastine), cromolyn, ipratropoim, leukotriene inhibitors (montlukast)
51
leukotriene inhibitors - name
montlukast
52
intranasal antihistamines - name
azelastine
53
The single most effective treatment for allergic rhinitis
intranasal steroids
54
allergic rhinitis - immunotherapy
DENSENSITIZATION | For extrinsic allergens that cannot be avoided
55
what should be done before immunotherapy
