Ear, Nose, and Throat Flashcards
viral sinusitis - sxs, dx, tx
common cold
Sxs: clear rhinorrhea, nasal congestion
- assoc. sx of H/A. cough, sneezing
- duration: < 10 days
PE: erythematous, engorged nasal mucosa
- non-purulent d/c (clear)
Tx: symptomatic
- saline nasal irrigation
- oral decongestion (pseudophedrine)
- nasal decongestant sprays (phenylephrine) - 3 day max for rebound swelling
bacterial sinusitis - acute, subacute, chronic
acute: >1 wk and <4 wk
subacute: 4-12 wks
chronic: > 12 wks
acute bacterial sinusitis - sxs, dx, tx
resulting secondary infection of mucous in sinuses due to stasis
sxs lasting > 10 days or worsening sxs after initial improvement
- facial PAIN
- PURULENT d/c
- fever
dx: clinical at first
- imaging if complications or not improving with ABX tx (CT prefered)
tx:
- AMOX: 7-10 days
- Macrolide (erythromycin, azithromycin) if PEN allergy
- Fluoroquinolones (Levaquin) if recent ABX or tx failure
Also supportive care w/ NSAIDS, etc.
chronic sinusitis
sinusitis lasting > 12 weeks
tx:
- intranasal corticosteroids (fluticasone)
- longer AMX tx: doxycycline (3 wls)
allergic rhinitis - sxs, tx
personal hx of atopy, seasonal
sxs: congestion, clear rhinorrhea
- EYE irritation (pruritus), sneezing
- cobble-stoning of posterior pharynx
- darkening under eyes
Tx:
- avoid allergen
- intranasal corticosteroids (delay onset of relief of 2 wks)
- OTC antihistmines in mean time
antihistamines - non-sedating vs. sedating
non-sedating (“-dine”)
- loradadine, fexafenadine
- hint: ok to dine
minimally sedating: cetirizine
sedating (“-mine”)
- brompheniramine, chlorpheniramine
- hint: sleep is mine
epistaxis - causes of anterior and posterior nasal cavity bleeds
nose bleed
- usually unilateral
Anterior nasal cavity (Kiesselbach plexus)
- causes: trauma, forceful blowing, rhinitis, dryness
- tx: direct pressure (nose clamp) and lean forward
- also cautery, packing
Posterior nasal cavity bleed
- assoc. w/ HTN, atherosclerosis
- tx: posterior packing referred to ENT
foreign body
occurs in PEDS to adults who are developmentally disabled
sxs:
- unilateral purulent nasal d/c
- foul smelling odor
- sneezing, bleeding, pain, mouth breathing
tx: removal, refer to ENT
nasal polyps
pale, boggy nasal mass (“grape-like” structure)
- commonly seen in pts w/ allergic rhinitis, aspirin sensitivity, asthma
Sxs:
- unilateral
- NOT sensitive to probing (vs. a foreign body that would be sensitive)
Tx:
- topical corticosteroids (1-3 mo)
- short-course oral steroids follow by topical nasal corticosteroids (severe)
- CT is not improving - surgery
aphthous ulcers - definition, duration, sxs, tx
canker sore
- common, found on non-keratinized mucosal surface
- painful, shallow ulcerations surrounded by red hallow
- last 7-10 days (painful), heal in 1-3 wks
risks: stress, acidic foods
tx: supportive
- topical corticosteroids (orabase = triamcinolone acetonide in adhesive base)
oral herpes simplex - definition, cause, sxs, tx
cold sores
- prodromal: tingling
- small vesicles, rupture, scab formation
- primary infection more severe
- recurrent on vermilion border (mild, self-limited)
- cause: HSV-1 > HSV-2
risks: stress, infection, trauma, sun exposure
tx:
- none or antiviral topical cream (acyclovir)
- first episode: systemic antiviral (acyclovir, valacyclovir)
Note: prevention of frequency recurrence: suppressive therapy w/ valacyclovir QD 5-7 yrs
oral candidiasis (thrush)
painful, intermittent sores in mouth
- creamy white patches over red mucosa
- CAN BY RUBBED OFF
risks: dentures, immune-compromised, recent steroids or ABX
- can be initial manifestation of HIV
dx:
- clinical
- biopsy if unclear (spores on wet prep)
tx:
- -azole (7 days)
- clotrimazole troches
- nystatin mouth rinse
oral leukoplakia - sxs, risks, dx, tx
white lesions caused by chronic irritation (dentures, tobacco)
- CANNOT be scraped off
- may be dysplasia or early squamous cell CA (ETOH or tobacco risks for SCC)
dx: biopsy or scraping
tx:
- ENT, surgical removal possible
acute pharyngitis - viral vs. bacterial
sore throat (common) - viral vs. bacterial key to identify strep and tx to avoid complications
viral:
- cough, rhinorrhea w/ no tonsillar exudate
bacterial (Centor Criteria):
- fever, tender ant. cervical nodes, NO cough, tonsillar exudate/petechiae, severe
- score determines ABX treatment (Pen V for adults, Amox for kids) vs. culture vs. symptomatic
complications of strep pharyngitis
antibody people make to group A strep can recognize normal protein on heart valves and attack it (think it’s foreign)
- rheumatic fever (myocarditis)
Post-strep: complexes between antibody and strep antigens deposit in the kidney = glomerulonephritis
scarlet fever: bright red rash
local abscess formation
GAS pharyngitis - tx
PEN V: adults
- if PEN allergy use macrolide: erythromycin or azithromycin
Note: Amox: kids (tastes better, only BID)
NOTE: do not Rx amox if possibly EBV (mono) - RASH
