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.
