A 22-year-old woman from Bangalore presents with a 5-day history of bilateral throat pain, fever (38.5°C), and dysphagia. On examination, both tonsils are enlarged, erythematous, and covered with a thick yellowish exudate. Anterior cervical lymph nodes are tender and enlarged. Rapid streptococcal antigen test (RSAT) is positive. She has no signs of airway compromise. What is the most appropriate next step in management?

Explanation

## Clinical Diagnosis The presentation—**bilateral** tonsillar enlargement with exudate, fever, dysphagia, and positive RSAT—is classic for **acute bacterial pharyngitis/tonsillitis** (likely Group A Streptococcus). ## Key Distinguishing Feature **High-Yield:** Bilateral involvement with no focal bulge, no medial displacement of tonsil, and no lateral pharyngeal wall bulge rules out **peritonsillar abscess** (which is unilateral and requires drainage). ## Management Algorithm ```mermaid flowchart TD A[Acute pharyngitis/tonsillitis]:::outcome --> B{Unilateral bulge?}:::decision B -->|Yes| C[Peritonsillar abscess]:::outcome --> D[Needle aspiration or I&D]:::action B -->|No| E[Uncomplicated acute tonsillitis]:::outcome --> F[Oral antibiotics + supportive care]:::action F --> G[Outpatient follow-up in 48 hrs]:::action E --> H{Severe, immunocompromised, or worsening?}:::decision H -->|Yes| I[IV antibiotics + admission]:::action H -->|No| G ``` ## Why Oral Antibiotics? 1. **Diagnosis confirmed**: RSAT positive = Group A Streptococcus. 2. **No abscess**: Bilateral, symmetric presentation with no focal fluctuance. 3. **No airway compromise**: Patient is stable. 4. **First-line therapy**: Oral penicillin V 500 mg QID × 10 days OR amoxicillin 500 mg TDS × 10 days (covers GAS). 5. **Supportive care**: Analgesics (paracetamol, ibuprofen), throat lozenges, warm salt water gargles, adequate hydration. 6. **Follow-up**: Clinical reassessment at 48 hours to confirm improvement and rule out complications. **Key Point:** Uncomplicated acute bacterial tonsillitis in a stable patient does NOT require hospitalization or IV antibiotics. Oral antibiotics are cost-effective and sufficient. **Clinical Pearl:** Failure to improve by 48 hours or worsening should prompt reassessment for abscess formation or alternative diagnosis (e.g., infectious mononucleosis, epiglottitis).
