Number of Conditions: 2

Bronchiolitis

Specialty: Emergency and Urgent Care

Category: Pediatric Emergencies

Sub-category: Respiratory Conditions

Symptoms:
runny nose; cough; wheezing; rapid breathing; retractions (chest wall pulling in); poor feeding; fever

Root Cause:
Inflammation and mucus build-up in the small airways (bronchioles), most commonly caused by respiratory syncytial virus (RSV).

How it's Diagnosed: videos
Clinical evaluation of symptoms; nasal swab tests for RSV may be used; chest X-rays only for severe cases.

Treatment:
Supportive care, including hydration, oxygen supplementation if needed, and suctioning of nasal secretions.

Medications:
No routine medications; bronchodilators or nebulized hypertonic saline may be used in selected cases.

Prevalence: How common the health condition is within a specific population.
Affects 20–30% of infants under 1 year old, with higher rates during winter and spring.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Premature birth, age under 6 months, exposure to cigarette smoke, crowded living conditions, daycare attendance.

Prognosis: The expected outcome or course of the condition over time.
Most recover with supportive care; severe cases may require hospitalization and oxygen therapy. Rarely leads to long-term respiratory issues.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Respiratory distress, hypoxia, dehydration, and secondary bacterial infections such as pneumonia.

Croup

Specialty: Emergency and Urgent Care

Category: Pediatric Emergencies

Sub-category: Respiratory Conditions

Symptoms:
barking cough; hoarseness; stridor (high-pitched wheezing); difficulty breathing; fever; nasal congestion

Root Cause:
Swelling and inflammation of the upper airway, typically caused by viral infections such as parainfluenza virus.

How it's Diagnosed: videos
Clinical evaluation based on characteristic symptoms and physical examination; imaging or additional tests are rarely needed.

Treatment:
Supportive care (hydration, humidified air), corticosteroids to reduce airway inflammation, and nebulized epinephrine for severe cases.

Medications:
Dexamethasone or prednisone (corticosteroids) to reduce inflammation; nebulized epinephrine (adrenergic agonist) for acute airway swelling.

Prevalence: How common the health condition is within a specific population.
Common in children aged 6 months to 3 years, particularly during fall and winter months.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Young age, exposure to viral infections, attending daycare, family history of respiratory conditions.

Prognosis: The expected outcome or course of the condition over time.
Most cases resolve with supportive care; severe cases respond well to medical treatment. Rarely requires hospitalization.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Severe airway obstruction, hypoxia, bacterial superinfection, and, in rare cases, respiratory failure.
