Background
- Acute (<4 weeks)
- Acute viral
- Acute bacterial (0.5-2% of cases)[1]
- Subacute (4-12 weeks)
- Chronic (>12 weeks)
- Other causes
- Fungal infections
- Allergies
Clinical Features
- Defined as 2 or more of the following:
- Blockage or congestion of nose
- Facial pain or pressure
- Hyposmia (diminished ability to smell)
- Anterior or posterior nasal discharge lasting <12wk
- Additional symptoms:
- Tooth pain
- Fever
- Sinus pressure while bending forward to changing head position
Differential Diagnosis
Rhinorrhea
- Upper respiratory infection, influenza
- Sinusitis
- Juvenile nasopharyngeal angiofibroma
- Nasal polyp
- Nasal mass
- Nasal foreign body
- CSF leak (e.g. basilar skull fracture)
- Toxic inhalation (e.g. selenium toxicity, neurotoxic shellfish poisoning)
Headache
Common
Killers
- Meningitis/encephalitis
- Myocardial ischemia
- Retropharyngeal abscess
- Intracranial Hemorrhage (ICH)
- SAH / sentinel bleed
- Acute obstructive hydrocephalus
- Space occupying lesions
- CVA
- Carbon monoxide poisoning
- Basilar artery dissection
- Preeclampsia
- Cerebral venous thrombosis
- Hypertensive emergency
- Depression
Maimers
- Giant cell arteritis of temporal artery (temporal arteritis)
- Idiopathic intracranial hypertension (Pseudotumor Cerebri)
- Acute Glaucoma
- Acute sinusitis
- Cavernous sinus thrombosis or cerebral sinus thrombosis
- Carotid artery dissection
Others
- Trigeminal neuralgia
- TMJ pain
- Post-lumbar puncture headache
- Dehydration
- Analgesia abuse
- Various ocular and dental problems
- Herpes zoster ophthalmicus
- Herpes zoster oticus
- Cryptococcosis
- Febrile headache (e.g. pyelonephritis, nonspecific viral infection)
- Ophthalmoplegic migraine
- Superior Vena Cava Syndrome
Aseptic Meningitis
- Viral
- Tuberculosis
- Lyme disease
- Syphilis
- Leptospirosis
- Fungal (AIDS, transplant, chemotherapy, chronic steroid use)
- Noninfectious
Evaluation
- Consider CT only for toxic patients (to rule-out complication)
IDSA Guidelines 2012[2]
- Highlights identifying factors for acute bacterial vs. viral rhinosinusitis
- Concern for bacterial (treat with antibiotics) if any of these:
- Purulent discharge and pain on face or teeth > 10 days without improvement
- Severe symptoms or fever > 39 plus symptoms > 3 days
- "Double sickening" - sinusitis symptoms at end of initially improving URI that lasted > 5 days
Management
<10 days of symptoms
- Symptomatic treatment because most likely viral
- Analgesia
- Mechanical irrigation with buffered, hypertonic saline
- Over the counter decongestants
- Intranasal decongestants (e.g. oxymetazoline for no more than 3d)
- Intranasal corticosteroids (e.g. mometasone furoate monohydrate, Flonase)[3]
- Avoid antibiotics
- Part of ACEP Choosing wisely
>10 days of symptoms
- Suspicious for bacterial origin especially with:
- No clinical improvement after 10 days
- Severe symptoms or high fever and purulent nasal discharge or facial pain lasting for at least 3–4 consecutive days at the beginning of illness
- Onset with newly worsening that were initially improving (‘‘doublesickening’’)
- Acute bacterial sinusitis[4]
- First line is amoxicillin-clavulanate (over amoxicillin alone) for 5-7 days, not 10-14
- Second line is fluoroquinolone or doxycycline
Antibiotic Failure
- Obtain culture
- Consider nosocomial bacterial sinusitis (e.g. after prolonged nasotracheal intubation)
- Consider foreign body
- Consider fungal treatment
Disposition
- Typically outpatient
Complications
- Meningitis
- Cavernous sinus thrombosis (ethmoid/sphenoid)
- Intracranial abscess
- Orbital cellulitis (ethmoid)
- Frontal bone osteomyelitis (Pott's puffy tumor)
- Extradural or subdural empyema
