Clinical Medicine 2 Flashcards
Etiology of acute sinusitis (rhino sinusitis)
Viral infection associated with common cold (URI). Few are bacterial related
Clinical presentation of acute sinusitis
- Nasal congestion/obstruction
- Purulent discharge (Bilateral viral, unilateral bacterial)
- Maxillary tooth pain (Bilateral is viral, unilateral is bacterial)
- Facial pain or pressure
- fever, fatigue cough
DX workup of acute sinusitis
Based on clinical symptoms. Purulent drainage. Must try and figure out if its viral or bacterial. Usually bacterial is secondary to the viral URI
Management of acute sinusitis
- If viral - goes away in 10 days
- Analgesics (NSAIDS)
- Saline irrigation
- Intranasal steroids
- Intranasal decongestants
- Amoxicillin
Complications of acute sinusitis
- Dental infections
- Intracranial involvement (abscess)
- Orbital cellulitis
Etiology of chronic sinusitis
Inflammatory condition involving the paranasal sinuses and lining of nasal passages that last longer than 12 weeks “untreated rhino sinusitis”
Clinical presentation of chronic sinusitis
- A/P nasal purulent drainage
- Nasal obstruction
- Facial pain/pressure
- Reduction or loss of sense of smell
- Mucosal thickening with polyps
DX workup of chronic sinusitis
- Rhinoscopy
2. CT/MRI
Complications of chronic sinusitis
High fever, double vision, proptosis, epistaxis - may indicate more severe conditions
Rhinocerebral mucormycosis
Fungal infection of the nasal cavity. Often seen in immunocompromised and diabetic pts
Causes of mucormycosis
From the fungal group rhizopus which are found in decaying soil. Airborne transmission
Clinical presentation of mucormycosis
- Acute sinusitis with fever
- Nasal congestion
- Clear discharge
- Spread to other structures
- Necrosis of the palate
Chlamydia
Most frequently reported infectious disease
URI
Viral induced infection of the upper respiratory tract (nose, mouth, upper lungs)
“common cold”
Types of URI infections
- Bronchitis
- Pertussis
- Acute rhinosinusitis
- Acute pharyngitis
- Acute otitis media
- Diptheria
- Infectious mononucleosis
Nasal vestibulitis
Staph aureus which may create folliculitis of the hairs. Often as a result of hair trimming
Clinical presentation of vestibulitis
Inflammation of the nasal vestibule, present with furuncle`
DX workup fro nasal vestibulitis
Nasal exam
Management of nasal vestibulitis
Drain furuncle, ABX - dicloxacillin. Topical - bacitracin
Common cold (URI) clinical presentation
nasal congestion, discharge, cough, sneezing, fever (low grade)
DX of URI
symptoms last
Management of URI
NO ABX!! Unless it is bacterial induced which is very rare.
Saline irrigation
Oxymetazoline - nasal anithistamine
