Bleeding into the upper airway can cause airway obstruction and death if not recognized promptly. Anesthesiologists are quite familiar with potential airway obstruction from acute epiglottitis, but they may be less familiar with the potential for airway obstruction from epiglottic hematoma. We report what we believe is the second case of epiglottic hematoma after anesthesia and surgery that led to an acute upper airway obstruction. Our case was unique in that there was no excessive airway trauma during tracheal intubation. Most important, this case emphasizes that patients receiving multiple anticoagulants--as our patient was--are at risk for airway bleeding, epiglottic hematoma formation, and airway obstruction.

Mucins 5AC (MUC5AC) and 5B (MUC5B) are the major mucins providing the organizing framework for the airway's mucus gel. We retrieved bronchial mucosal biopsies and bronchial wash (BW) samples through bronchoscopy from patients with chronic obstructive pulmonary disease ( = 38), healthy never-smokers ( = 40), and smokers with normal lung function ( = 40). The expression of MUC5AC and MUC5B was assessed immunohistochemically.

: Continuous positive airway pressure (CPAP) is used to treat patients with obstructive sleep apnea (OSA) and has proven clinical efficacy for this condition. However, the objective method to determine the appropriate CPAP level for treatment is still unclear. Patients with OSA typically exhibit irregular respiratory efforts due to obstruction or narrowing of the upper airway during sleep.

Nasal airway obstruction is a frequent complaint in an otolaryngology clinic and is often multifactorial. Anatomic contributors may include a nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise. Septoplasty and inferior turbinate reduction are one of the most common procedures performed by an otolaryngologist.

Iron regulatory protein 2 (IRP2), a post-transcriptional regulator of cellular iron metabolism has been associated with susceptibility to chronic obstructive pulmonary disease (COPD). Resistive breathing (RB) is the hallmark of the pathophysiology of obstructive airway diseases, especially during exacerbations, where increased mechanical stress is imposed on the lung. We have previously shown that RB, through tracheal banding, mimicking severe airway obstruction, induces pulmonary inflammation and injury in previously healthy mice.

Thermal burns of the larynx are uncommon but can lead to serious upper airway obstruction due to edema and bleeding, especially in children who may struggle to communicate their symptoms effectively. This report presents the case of a one-year-and-seven-month-old boy who developed stridor and respiratory distress after eating a heated potato, which ultimately required tracheal intubation. The initial evaluation suggested foreign body aspiration; however, laryngoscopy confirmed significant arytenoid swelling and airway narrowing due to thermal burns.
