Vocal cord dysfunction in bronchial asthma. A review article
Bibliographic record
Abstract
INTRODUCTION: Vocal cord dysfunction (VCD) is a condition in which the larynx exhibits paradoxical vocal cord adduction during inspiration, resulting in extra-thoracic variable airway obstruction. It has been described as a mimic of asthma, and hence, many patients with VCD are diagnosed as difficult-to-treat asthma and suffer significant morbidity as such. METHODS: In completing this review we searched the literature using the database from MEDLINE, PubMed, and the Cochrane library using the medical terms "vocal cord/vocal cord dysfunction and asthma". RESULTS: During the last few decades, many publications have described many conditions that may cause or coexist with VCD. In addition, the association between asthma and VCD was recognized. In this narrative review we provide an overview of the current knowledge about VCD and, in particular its relationship to asthma. We also provide a pragmatic diagnostic algorithm and treatment options based on our collaborative multi-disciplinary management of patients attending a difficult to control asthma clinic. CONCLUSION: Most VCD patients present with inadequately controlled asthma rather than the typical symptoms described in association with VCD. Careful diagnostic strategy as outlined in this review may be helpful in confirming the diagnosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
