Vocal cord dysfunction (VCD) can be triggered by environmental or occupational irritants. Recognizing this link is crucial for accurate diagnosis and treatment of respiratory symptoms following exposure.

Area of Science:

  • Medicine
  • Pulmonology
  • Occupational Health

Background:

  • Vocal cord dysfunction (VCD) is frequently misdiagnosed, often mistaken for asthma.
  • The relationship between VCD and specific environmental or occupational exposures remains poorly understood.

Observation:

  • This study investigated eleven cases of VCD with a clear temporal link to irritant exposure.
  • A case-control study compared VCD patients exposed to irritants (IVCD) with non-exposed VCD controls.

Findings:

  • Statistical differences were observed in ethnicity and chest discomfort between IVCD cases and controls.
  • No significant differences were found in gender, smoking status, symptoms, or pulmonary function.
  • Diverse irritant exposures were associated with the development of IVCD.

Implications:

  • Vocal cord dysfunction due to irritant exposure (IVCD) should be strongly considered in patients with new respiratory symptoms after exposure.
  • This highlights the importance of detailed exposure history in diagnosing VCD.
  • Further research into specific irritants and VCD mechanisms is warranted.
