Difficulty: MediumInfectious Diseases

A 3232-year-old woman comes to the clinic reporting facial pressure and nasal congestion that began 55 days ago. She states her symptoms started with a mild scratchy throat and clear rhinorrhea but have since progressed. Over the past two days, she has noticed thick, yellow-green nasal discharge and worsening pressure over her cheeks, which is exacerbated when leaning forward. She reports a subjective mild fever at home two days ago but has been afebrile since. Her medical history is unremarkable, and she takes no daily medications. Her temperature is 37.2∘C37.2^\circ\text{C} (99.0∘F99.0^\circ\text{F}), blood pressure is 118/76 mmHg118/76\text{ mmHg}, and pulse is 78/min78/\text{min}. Physical examination reveals erythematous, edematous nasal mucosa with purulent drainage in the bilateral middle meatus. There is mild tenderness to palpation over the maxillary sinuses. Which of the following is the most appropriate next step in management?

  1. Reassurance and initiation of symptomatic therapyAnswer
  2. B
    Prescription for oral cefdinir
  3. C
    Prescription for oral clarithromycin
  4. D
    Prescription for oral doxycycline
  5. E
    Prescription for oral moxifloxacin

Answer

The most appropriate next step in management is reassurance and initiation of symptomatic therapy, as the patient's presentation is highly consistent with acute viral rhinosinusitis.
The correct approach is reassurance and symptomatic therapy. This patient presents with classic signs of acute rhinosinusitis (nasal congestion, purulent discharge, facial pain). Acute rhinosinusitis is overwhelmingly viral in etiology. According to current guidelines, acute bacterial rhinosinusitis is diagnosed clinically only if a patient meets at least one of three criteria: 1) symptoms lasting ≥10\ge 10 days without clinical improvement, 2) severe symptoms at onset including a high fever (≥39∘C\ge 39^\circ\text{C}) and purulent nasal discharge for ≥3\ge 3 consecutive days, or 3) 'double sickening' (worsening symptoms after initial improvement). Because this patient has only had symptoms for 55 days and lacks severe features or biphasic worsening, she has acute viral rhinosinusitis. Symptomatic management (e.g., intranasal saline irrigation, analgesics) is the standard of care.

Step-by-Step Solution

1
Evaluate the duration and trajectory of the patient's symptoms.
The patient has had symptoms for 5 days without severe onset features (e.g., high fever) or a biphasic illness pattern (worsening after initial improvement).
Differentiating viral from bacterial rhinosinusitis relies entirely on clinical criteria, which dictates the need for antimicrobial therapy.
2
Determine the most appropriate intervention based on the diagnosis.
Observation and supportive care (e.g., intranasal saline, analgesics) are selected.
Antibiotics do not alter the clinical course of viral infections, and avoiding them adheres to core antibiotic stewardship principles.
