Exercise and Sinonasal Diseases: Key Interactions and Management Pearls.

The nose filters, moistens, and warms inspired air at rest and during activity. Exercise is associated with an increase in nasal airflow and a decrease in resistance to that flow. Mechanistically, changes in the nasal mucosa during exercise may increase neutrophilic infiltration, impair olfaction, and prolong mucociliary transport time.

Validation of the Nasal Obstruction Symptom Evaluation Scale in Mexican Adults.

Background: Nasal obstruction is a feeling of impaired airflow through the nose, caused by diverse factors with high prevalence. There are numerous methods to study it, being the most important subjective instrument the Nasal Obstruction Symptom Evaluation score, NOSE, with good structural validity and internal consistency. It has been translated and validated in several languages, including European Spanish, but hasn't been validated in Mexico.

Effect of LTRA in L-ASA Challenge for Aspirin-Exacerbated Respiratory Disease Diagnosis.

Background: Aspirin-exacerbated respiratory disease (AERD) consists of asthma, chronic rhinosinusitis with polyps, and hypersensitivity to aspirin and/or nonsteroidal anti-inflammatory drugs (NSAIDs). Nasal Lysine Aspirin Challenge is an effective tool for the diagnosis of hypersensitivity to aspirin and/or NSAIDs in patients with AERD. However, there is no unified international consensus version to perform nasal provocation tests (NPTs).
