Differentiating vocal cord dysfunction from asthma.

Area of Science:

• Pediatric Pulmonology
• Laryngology

Background:

• Vocal cord dysfunction (VCD) presents with symptoms like dyspnea, wheezing, and stridor in pediatric patients.
• These symptoms, often occurring during exercise, can be misdiagnosed as asthma, especially when unresponsive to standard treatments.

Purpose of the Study:

• To highlight the importance of accurately diagnosing VCD in children.
• To differentiate VCD from asthma and guide appropriate therapeutic strategies.

Main Methods:

• Diagnosis relies on fiberoptic laryngoscopy, ideally performed during symptomatic episodes.
• Exercise challenges, including continuous laryngoscopy during exercise (treadmill, ergometer, swimming), are employed for diagnosing exercise-induced VCD.

Main Results:

• VCD symptoms can mimic asthma, leading to misdiagnosis and ineffective treatment.
• Identifying VCD is crucial for initiating correct management, distinguishing it from or alongside asthma.

Conclusions:

• Accurate diagnosis of VCD is essential for pediatric patients presenting with respiratory symptoms.
• Distinguishing VCD from asthma ensures appropriate treatment, addressing either condition alone or concurrently.
