    Study Notes

    Upper Respiratory Tract Infections (URIs)

    • Most frequent infection leading to physician visits, totaling 25 million annually pre-COVID in the US; rates increased by 30% since 2022.
    • Major contributor to bacterial antibiotic resistance due to misuse and over-prescription of antibiotics.
    • Four primary types of URIs:
      • Acute otitis media
      • Acute rhinosinusitis
      • Acute pharyngitis
      • Acute laryngitis

    Otitis Media (OM)

    • Represents inflammation of the middle ear, with three forms:
      • Acute otitis media (AOM)
      • Otitis media with effusion (OME) also known as "glue ear."
      • Chronic otitis media (COM) leads to long-term inflammation and multi-drug resistant infections.
    • Over 700 million global cases annually, with 50% affecting children.

    Acute Pharyngitis (AP)

    • Most commonly caused by Group A beta-hemolytic streptococcus (GABHS); other viral and non-streptococcal bacterial causes also possible.
    • Symptoms include sudden sore throat, fever, and constitutional signs, typically resolving in 3-5 days.
    • Clinical signs for GABHS and viral causes are often similar.

    Diagnosis of GABHS Pharyngitis

    • Throat swabs utilized for:
      • Rapid antigen-detection test (RADT)
      • Gold standard microbiological culture.

    Treatment Considerations

    • Viral AP management involves symptomatic relief with anti-pyretics and analgesics.
    • GABHS treatment includes:
      • First-line: Penicillin V, Penicillin G benzathine, Amoxicillin (10-day course).
      • Alternatives for penicillin allergy: Cephalexin, Clindamycin, Azithromycin, Clarithromycin.

    Acute Laryngitis (AL)

    • Inflammation of the larynx, typically self-limiting and lasts 3-7 days; chronic if >3 weeks.
    • Commonly viral in origin; pediatric cases may include "croup."
    • Symptoms: voice changes, dry cough, throat pain, fever; often associated with gastroesophageal reflux disease (GERD).

    General Diagnosis and Treatment for AL

    • Diagnosis through laryngoscope examination.
    • Treatment includes voice rest, supportive care, and corticosteroids for croup.

    Risk Factors and Clinical Management

    • Common risk factors shared between different URIs, with a focus on ensuring proper antibiotic use to prevent complications and resistance.

    Study Question Highlights

    • Importance of differentiating viral vs bacterial infections in treatment decisions.
    • Understanding of conditions leading to acute otitis media and appropriate treatment choices based on patient history and symptoms.
    • Recognizing signs that distinguish laryngitis from other URIs, with particular focus on aphonia as a unique symptom.
