1. transillumination: shine light through sinus into the mouth, only significant if asymm (detects if sinus is full) 2. sinus puncture/sinus tap & aspirate (GOLD STANDARD) but only done in clinical research 3. radiology: CT for recurrent ABRS (maybe a structural cause)

rhinosinusitis Flashcards by Jacqui Joseph

when evaluating a pt with sinusitis-like symptoms, what will you expect if they start with a runny nose? sore throat? if there is presence of exudate?

runny nose: sinusitis
sore throat: strep
exudate: bacterial over viral

what is the likely cause of rhinosinusitis?

viral: makes up 90-99% of sinusitis cases

bacterial 0.5-2% …except in children admitted to ER for high fever.. liklihood for either is about the same

which clinical presentations qualify pts to be evaluated for AVRS vs ABRS (one of three)?

PERSISTENT S&S of rhinosinusitis for >10 days, no improvement
SEVERE symp (high fever, purulent nasal discharge, or facial pain): 3-4 consecutive days
WORSENING symp. or “double-sickening” (better then worse again) >3-4 days.

for both at-risk and not at risk pts what do you do if they are improving on treatment in 3-5 days?

at-risk: complete 7-10 days of abx

not at-risk: complete 5-7 days of abx

what to do if pt (at-risk or not at-risk) if worsening or no improvement in 3-5 days?
if improvement?
if still no improvement in 3-5 days after?

broaden coverage or switch to another abx class
improvement:
no-risk: finish 5-7 days
at-risk: finish 7-10 days

if still not improving 3-5 days, refer to specialist:

sinus CT or MRI
direct sinus puncture culture/sinus tap (GOLD STANDARD) or middle meatal cultures

bacterial sinusitis: what are the two causes?

community acquired: S. PNEUMO, H. FLU, M. CATARRHALIS & Strep A, Staph (caps= 3 most common)
nosocomial (hospital): nasogastric tubes, staph/pseudomonas/other gram neg.

ABRS PE: vital signs, eyes, nose, throat, face, neck, chest

Vital signs – may be febrile, otherwise wnl
Eyes – possible clear D/C, otherwise wnl
Nose – turbinates swollen, possible purulent D/C visible
Throat – likely inflamed, absence of tonsillar exudates, possible foul breath, possible posterior drainage, possible posterior pharyngeal cobblestoning if chronic drainage
Face – tenderness to palpation/percussion of maxillary and/or frontal sinuses
Neck – possible anterior cervical lymphadenopathy
Chest – normal exam, but cough possible

3 tests for ABRS

Study These Flashcards

transillumination: shine light through sinus into the mouth, only significant if asymm (detects if sinus is full)
sinus puncture/sinus tap & aspirate (GOLD STANDARD) but only done in clinical research
radiology: CT for recurrent ABRS (maybe a structural cause)

treatment for ABRS

Study These Flashcards

cover big 3 pathogens (M. Catt, H. Flu, S. Pneumo)

amox-clav (augmentin
if PCN allergic….3rd gen cephalosporins
respiratory fluoroQs (levofloxacin) ONLY if no other good alternative (bad ADRs)
* 5-7 txt for adults, 10-14 for kids, longer txt for chronic or recurrent
* once symptoms subside, take for 2 more days the stop

what should always be included in Ddx of sinusitis?

Study These Flashcards

paranasal sinus cancer (persistent pain, epistaxis, prolonged clinical course)

AVRS vs ABRS: S&S?

Study These Flashcards

same S&S, viral is less severe (aka URI)
almost never have a fever
resolves on its own 5-7 days (shorter than ABRS)

Hadley’s txt of garden variety sinus infections

Study These Flashcards

bacterial = augmentin
afrin: 2 sprays BID for 4 days
anti-inflamm meds for comfort (ibuprofen or naproxen)
guafenesin (mucinex/robitussin) & fluids
saline rinse
allergic trigger? nasal steroid spray w/ afrin (maybe chronic antiHistamine?)
pt education

AVRS txt: what events do you want to block? what 5 meds do you want to use?

Study These Flashcards

block inflamm events: nasal fluid production &amp; inflamm.
meds:
antihistamines
NSAIDS
cough suppressant
decongestants
mucolytics

why do you want to avoid 1st gen antihistamines for ABRS:?

Study These Flashcards

they thicken secretions

*while expectorants (guafenisin aka mucinex) will thin them

what is chronic sinusitis?

Study These Flashcards

> 12 wks of S&S, issues w/ mucociliary clearance

mucopurulent drainage
nasal obstruction
facial pain
purulent mucus/edema in meatus/ethmoid OR polyps OR image showing inflamm of sinuses

what is recurrent sinusitis?

Study These Flashcards

4+ episodes a year with absent symptoms between episodes

what is included in the PE for chronic sinusitis?

1. nasal exam w/ speculum & endoscope (purulent drainage, polyps, septal deviation, turbinate hypertrophy/edema) 2. sinus palpation/percussion for tenderness 3. ears for TM fluid, neck for LAD, throat for PND, ocular for oculomotor involvement, lung for lower RI/asthma

txt for chronic sinusitis? if it is bacterial-chronic?

no gold standard, refer to ENT (maybe intranasal steroids, decong., mucolytics) true chronic is rare 1 month abx if bacterial-chronic

what to look at for general Dx of allergic rhinosinusitis

look at history: (perennial (likely from house) vs seasonal(hay fever)) chronicity: maybe recurrent ABRS/AVRS (3-4 infections/year S&S: clear rhinorrhea with allergy symp. (sneezy, itchy) *clear fluid behind TM

3 giveaway signs of allergic rhinosinusitis

1. allergic salute 2. crease in nose (from allergic salute) 3. allergic shiners

allergies are closely tied to what other illness?

asthma

3 types of therapy for allergies Rh?

1. avoidance 2. drug: inhibit action of released mediators, reversal of vascular and inflamm response 3. immunotherapy: repeated long-term injection of allergen to blunt rxn

what meds are used for drug therapy of allergic rhinosinutisis?

antiH1 anticholinergic (atrovent spray) nasal steroid spray mast cell stabilizers (inhibit degradation) leukotriene antagonists (inhibit vascular permeability & inflamm)

what is vasomotor rhinosinusitis?

trigger by smells, stress, and substances (smoke, cold air) | = sneezing and runny nose, congestion (parasymp overactivity of nasopharynx)

txt for vasomotor rhinosinusitis?

atrovent (aka ipratropium) spray PRN *don't use nasal steroid spray * don't use decongestants maintenance med so you don't want to use steroids or decongestants all the time

pts who are sensitive to vasomotos Rh also tend to get what?

migraines

nasal polyps: what are they? can they be removed?

inflamed outgrowths of nasal mucosa | -may be removed but most return

what are nasal polyps assosciated with?

``` asthma chronic sinus infections cystic fibrosis allergic rhinitis hyposmia (reduced ability to smell) ```

what is samter's triad?

type 1 hypersens. 1. rhino-sinusitis 2. asthma and aspirin sensitivity 3. nasal polyps

symptoms of exposure to aspirin or NSAIDS for those with samter's triad? txt for this?

``` flushing of head/neck/chest bronchoconstriction wheezing cyanosis N/V/D txt: bronchodilators ```
