Working Towards a Common Transatlantic Approach for Evaluation of Exercise-Induced Laryngeal Obstruction

Exertional dyspnea can be a manifestation of dysfunction in a variety of organ systems. Exercise-induced laryngeal obstruction (EILO), a condition previously known as vocal cord dysfunction and paradoxic vocal fold motion, is defined as inappropriate, reversible narrowing of the larynx during vigorous exercise. EILO is usually characterized by typical symptoms, which nevertheless frequently are confused with those of other conditions, including asthma. Laryngoscopy performed as symptoms evolve from rest to peak exercise is pivotal in patient work-up. Moving forward, laryngoscopy findings that definitively characterize EILO need to be defined as do objective measures that can quantitate absolute laryngeal measurements during exercise.

Publication date: Available online 14 February 2020Source: The Journal of Allergy and Clinical Immunology: In PracticeAuthor(s): J.H. Hull, Krystelle Godbout, Louis-Philippe BouletAbstractBreathlessness during sport can be caused by a variety of cardiorespiratory conditions, but when associated with stridor, usually arises from an upper airway etiology. The term exercise-induced laryngeal obstruction (EILO) is now used to describe the phenomonen of transient glottic closure occurring in association with physical activity.Exercise related laryngeal closure is most commonly encountered in athletic individuals and likely affe...

CONCLUSION: Post-deployment pulmonary evaluation should focus on common diseases such as asthma and airway hyperreactivity, and include testing for upper airway disorders. Diffuse lung diseases were rarely diagnosed while numerous co-morbidities were common. PMID: 32017933 [PubMed - as supplied by publisher]

A 42 year old female with past medical history of asthma and recent admission for Alprazolam overdose presented to our hospital with dyspnea and generalized weakness.. She was noted by paramedics to be hypoxic, hypotensive and bradycardic, and she was intubated in the field prior to arrival.. Medication prior to admission, Albuterol HFA. Patient had no known drug allergies. On presentation to the emergency department, patient appeared critically ill, hypotensive to 74/50 , hypoxic with oxygen saturation of 60%, heart rate of 137 BPM, respiratory rate 15/min, temp 99 F, and unresponsive to verbal stimuli. Endotrachial tube ...

We report the use of individualised field tests (IFT) to investigate exercise induced symptoms amongst asthmatic children referred to a tertiary respiratory service. Tests were completed by a physiotherapist and paediatrician and included the facility to perform fibre optic laryngoscopy in those with symptoms suggestive of vocal cord dysfunction (VCD).26 assessments were performed (Male 9: Female 17; age 11 - 17 years, 1child of 6 years).7 Were positive for EIB (Decreased FEV1> 12%, 5-15mins post exercise). 13 had signs of dysfunctional breathing. 5 developed signs of upper airway obstruction due to VCD.1 test revealed ...

ConclusionsAECRS are negatively associated with the level of asthma control in asthmatic CRS patients, independent of CRS symptom severity.
