Sore Throat and Pharyngitis

Overview of Pharyngitis

Pharyngitis refers to a sore throat, and it is important to determine whether it is of viral or bacterial origin to manage it effectively.

Viral Pharyngitis

  • Common Cold: Viral pharyngitis is often referred to as the common cold.

  • Onset: Typically has a gradual onset. Symptoms may arise over a few days.

  • Symptoms: Patients, particularly children, may report that “my spit tastes weird.” They commonly complain of a sore throat, which is not usually severe compared to bacterial pharyngitis.

  • Examination Findings:

    • Edema and inflammation of the varix and tonsils may be present, but typically lack overwhelming symptoms.

    • There is an absence of white patches, which differentiates it from a bacterial infection.

    • Some children with enlarged (kissing) tonsils may develop ulcers due to inflammation and friction.

  • Fever: If present, it is usually low grade and may fluctuate.

  • Other Symptoms: Hoarseness, cough, runny nose, conjunctivitis (red eyes), malaise, and possible anorexia.

  • Duration: Usually lasts around three to four days.

  • Management: Focus on symptom management which includes:

    1. Antipyretics (age-appropriate)

    2. Hydration (encouraging fluid intake)

    3. Rest

Bacterial Pharyngitis (Strep Throat)

  • Common Suspect: Most often caused by Streptococcus bacteria, commonly referred to as strep throat. Other bacteria might be involved occasionally, such as Staphylococcus.

  • Onset: Abrupt onset is typical, especially in school-aged children.

  • Symptoms:

    • Severe sore throat that children can specifically identify as the strep throat feeling.

    • Erythema of the throat, with tonsils often inflamed.

    • Presence of pustules or white patches on the tonsils, although not all patients will exhibit these features.

    • Gastrointestinal symptoms such as abdominal pain and vomiting are more common in children than adults with strep throat.

  • Cervical Lymphadenopathy: Tender enlargement of cervical lymph nodes.

  • Duration: Lasts approximately three to five days.

  • Management: Requires an antibiotic treatment for recovery.

    • Antibiotics: Oral penicillin is commonly administered two to three times a day for ten days.

    • Symptom Management: Same as for viral pharyngitis including antipyretics and hydration.

  • Contagiousness: Strep throat is highly contagious, necessitating a return to school only 24 hours post antibiotic treatment commencement.

  • Reinfection Prevention: Educate parents on replacing the child's toothbrush after starting antibiotics to prevent reinfections.

Upper Respiratory Infections (URI)

  • Definition: Refers broadly to conditions like viral pharyngitis.

  • Over-the-Counter Products: Generally not recommended for children due to potential side effects, including excess alcohol content.

  • Antihistamines: Not effective in treating colds in kids; parents should be informed accordingly.

  • Cough Suppressants: Should be cautious due to alcohol content. Only consider for older children, under appropriate recommendation.

Tonsillectomy and Its Indications

  • Definition: Surgical removal of the tonsils, typically only indicated in severe recurrent infections.

  • Contraindications: Active infections or anatomical abnormalities (e.g., cleft palate).

  • Post-operative Care:

    • Positioning to prevent aspiration is crucial (side-lying or prone).

    • Clear liquid diet until the gag reflex returns; avoid milk products due to their coating effects which increase bleeding risk.

    • Watch for signs of bleeding, tachycardia as a possible indication of hemorrhage.

  • Counseling Points for Parents: Importance of replacing toothbrushes after tonsillectomy to prevent reinfections.

Croup (Laryngotracheobronchitis)

  • Definition: A respiratory infection often seen in children, characterized by a distinctive barking cough.

  • Symptoms: Harsh, metallic cough, inspiratory stridor, and hoarseness. Symptoms often exacerbate at night due to the child’s recumbent position.

  • Management:

    • Positioning (sit upright)

    • Exposure to cool air may provide immediate relief

    • Steam inhalation may alleviate symptoms at home.

    • Racemic epinephrine and corticosteroids may be used when symptoms are severe.

  • Emergency Protocol: Continuous monitoring for progression; observe for signs of distress or hypoxia.

Epiglottitis

  • Causes: Typically caused by Haemophilus influenzae (Hib); vaccination has decreased occurrence.

  • Contagiousness: Highly contagious and requires immediate isolation.

  • Presentation: Drooling, dysphagia, dyspnea, and “croaking” sound during respiration.

  • Intervention: Keep the child calm, upright and do not attempt to visualize the throat with a tongue depressor to prevent airway collapse.

    • Be prepared for possible intubation.

  • Management: Potential use of racemic epinephrine and corticosteroids to reduce inflammation.

Bronchiolitis (RSV)

  • Description: Inflammatory condition affecting the bronchioles primarily due to RSV in infants.

  • Symptoms: Tachypnea (60-80 bpm), wheezing, retractions, nasal flaring, and possible cyanosis.

  • Management: Focus on hydration, oxygen supplementation, and monitoring.

    • Avoid antibiotics unless secondary bacterial infections occur.

Pneumonia

  • Management: Similar to bronchiolitis; consider antibiotics for bacterial forms but not for viral. Key interventions: fluids, oxygen therapy, and monitoring.

Cystic Fibrosis

  • Overview: Affects multiple systems including respiratory, digestive, and reproductive systems.

  • Diagnosis: Based on sweat chloride test (greater than 60 mEq/L is diagnostic).

  • Management: High-calorie diet, pancreatic enzyme replacement, and airway clearance therapies including CPT (chest physiotherapy).

Asthma

  • Definition: Characterized by airway hyper-responsiveness leading to Bronchospasm.

  • Symptoms: Wheezing, chest tightness, shortness of breath, cough, and increased work of breathing. Symptoms typically worsen at night.

  • Management: Bronchodilators as rescuers, corticosteroids for inflammation, and peak flow monitoring for management.

  • Emergency Signs: Identify worsening cough, breathlessness, ineffective responses to bronchodilators, and difficulty in walking or talking.

Summary and Management Principles

  • Each respiratory condition has its specific symptoms and management guidelines, focusing on symptom relief and prevention of complications.

  • Reinforce infection control measures in both acute and chronic cases.
