ENT Flashcards
What are the common URI bugs?
H. influenza
M. catarrhalis
Strep Pneumoniae
What are the classic clinical presentation of acute otitis media (AOM)?
unilateral ear pain relieved w/ pulling on pina
AOM physical exam findings
- loss of light reflex (opaque)
- bulging erythematous TM (esp. if yellow or hemorrhagic = bacterial)
- fluid befind TM (bubbles)
- if TM immobile = Dx
How is AOM Dx’d?
Clx: immobile TM
w/ pneumatic insulflation (puff air –> rigid TM = +)
What are signs that an AOM is bacterial in etiology?
- A bulging tympanic membrane, especially if yellow or hemorrhagic
- Perforation of the tympanic membrane with purulent discharge
How is AOM Tx’d?
<6wks:
- Ix bacteremia, go to ED
6wk-6mo:
- analgesics
- Amox x10 days
> 6mo
w/ RFs: Immediate Tx for: - child w/ high fever (>39) - mod-sev systemically ill or - very severe otalgia or - significantly ill >48 hrs
low RFs: - watchful waiting + analgesics OR give Abx Rx to parents to use if child doesn't improve w/in 48hrs Drug: Amoxicillin <2y/o - x10 days >2 y/o - x5 days
- if/ Tx fail = Amox-clav cefprozil, Ceftriaxone im/iv × 3 days ...consider tympanostomy tubes
How do you Tx recurrent AOM (medically and procedurally)?
Amox-clav 10-14 d
- if >3x/6mo or 4x/yr = Tympanostomy tubes
- pen allergic = Clarithromycin or azithromycin
if Tx fail:
Clindamycin
or FQ (levoflox)
How do the presentations of viral, allergic, and bacterial conjunctivitis generally differ?
VIRAL: - red eye - minimal itch - profuse serous d/c "gritty" -affects 2nd eye 24-48 hrs later
BACTERIAL:
- red eye
- minimal itch
- mod, mucopurulent-purulent (all day)
- usually unilateral
HYPER-acute bacterial:
yellow-green purulent discharge, redness, irritation and tenderness to palpation.
ALLERGIC:
- red eye
- VERY ITCHY
- mod, serous or mucoid
TX for conjunctivitis
all etiologies usually self-limiting
supportive:
- throw out contacts
- wash bed sheets
if Viral:
- OTC antihistamines
if Bacterial:
- Abx (polymyxin B/gramicidin drops, 4-6x/day x7-10 days.. continue 2 days after sxs resolve)
- if no improvement 48 hrs, switch to broad spec drops: trimethoprim/polymyxin B, ophthalmic ointments containing erythromycin or bacitracin
Dacryoadenitis definition
blocked lacrimal glands
Dacryoadenitis - signs and symptoms
Signs & symptoms
- Swelling of upper lid
- Lid redness & erythema
- Lid pain
- Excess tearing or discharge -Swelling of preauricular nodes
Darcryoadenitis - Tx
Management
- Warm compresses
- Think malignancy if no improvement
if purulent d/c, start first-generation cephalosporins to cover G+ves (eg, Keflex 500 mg qid) until culture results are obtained
Strabismus (Tropia) - Definition, Ix, Mx
Def: crossed eyed
Ix: light reflex, cover-uncover test
(Affected eye will drift when covered, then moves quickly back if cover is removed)
- Differentiate congenital from acquired (may be vision-threatening or life-threatening)
Mx: refer to ophtho
Otitis Externa - nick name/Etiology
“swimmer’s ear”
(pseudomonas)
digital trauma
Otitis Externa - Clinical presentation
- unilat. ear pain (otalgia)
- worse pain with manipulation of tragus
- hearing loss
- otorrhea
- fullness
- itching
- recent exposure to water
What are the 2 most common pathogens that cause Otitis Externa?
Pseudomonas aeruginosa (20–60%) and Staphylococcus aureus (10–70%) (and strep)
AOE = bacterial 90% of time
How do you treat otitis externa?
TX = NONE, self resolving…
(analgesics)
summary: if doesn’t and prs looks toxic –> abx/steroid drops
Bacterial:
- neo/poly/HC only if TM intact, - FQ ex. cipro (use a wick if canal is swollen),
- systemic therapy if canal is swollen shut or pt is immunocompromised/DM
- Fungal: acetic acid/HC drops, clotrimazole drops
- Bacterial vs fungal? CASH (drying) powder covers both
- Chronic treat eczema with steroid cream, then use vinegar/water washes and avoid Q-tips
- Malignant emergent referral to ENT
What is a potential complication if otitis extern?
Malignant otitis externa = osteomyelitis of temporal bone as a result of chronic infection in DM, not cancerous!
What are the risk factors/causes for oral candidiasis?
Newborns Uncontrolled Diabetes HIV/AIDS Chemotherpy Side effect of inhaled steroids Side effect of antibiotics Dentures or poor hygiene
What are the Signs & symptoms of oral candidiasis? aka- “thrush”
Signs & symptoms:
-Pseudomembranous form is most common: white plaques
(when you scrape, either red sore or still white under)
-Angular cheilitis with chronic lip-lickers
-Glossitis with broad spectrum antibiotic use
-Cottony feeling in mouth
-Loss of taste
-Pain with eating and swallowing
-May be asymptomatic
Tx for oral candidiasis?
Address underlying cause
Fluconazole 100mg x 7 days for non-immunocompromised patients
½ hydrogen peroxide mouth rinse
OR
-Infants: oral NYSTATIN swabs for 7-14 days, boiling of bottle nipples and pacifiers
-Older children: oral NYSTATIN rinses x14 days or systemic fluconazole PO if severe
(200mg po x1 day, then 100mg po x7 days)
What Ix do you do for oral candidiasis?
Workup
- Lesions can be scraped off and may bleed
- Culture of scrapings (KOH prep)
- Microscopic examination of scrapings
What is Samter’s triad?
syndrome of:
aspirin sensitivity,
nasal polyposis, and
asthma
often seen with allergic rhinitis, frequently leading to severe pansinusitis
What are the S/Sxs of allergic rhinitis?
repetitive sneezing, pruritus of nose, eyes, palate, ears, clear rhinorrhea, nasal congestion, postnasal drip, epistaxis, allergic shiners, Dennie’s lines, allergic salute, retracted TMs, serous effusions, swollen or boggy turbinates, hyperplasia of palate or posterior pharynx
Allergic rhinitis management is….?
- Instruct patients in allergen avoidance: closed windows, bed cases, washing linens weekly, removing stuffed animals, cockroach poison, mould precautions, HEPA filters
- Nasal saline sprays or rinses
- Oral decongestants
- Nasal steroids: fluticasone, flunisolide
- 1st or 2nd gen antihistamines: cetirizine and fexofenadine ok for infants > 6 mo
- Leukotriene inhibitor
- Refer to allergist for kids with mod-severe disease, prolonged rhinitis despite intervention, coexisting asthma or nasal polyps, recurrent otitis media or sinusitis
