Corrosion casting of the subglottis following endotracheal tube intubation injury: a pilot study in Yorkshire piglets.
Subglottic stenosis can result from endotracheal tube injury. The mechanism by which this occurs, however, is not well understood. The purpose of this study was to examine the role of angiogenesis, hypoxia and ischemia in subglottic mucosal injury following endotracheal intubation. ⋯ Subglottic injury due to intubation and hypoxia may lead to decreased angiogenesis and increased blood vessel damage resulting in extravasation of fluid and a decreased propensity toward wound healing in this animal model.

ReviewA bone to pick? Fish bones of the upper aerodigestive tract: review of the literature.
Fish bones are of particular interest to the otolaryngologist as accidental ingestion is one of the most common reasons for otolaryngology-related emergency department referrals. Furthermore, removal of fish bones deeply lodged in the oropharynx or hypopharynx can be both hazardous and technically difficult, and failure to accomplish safe removal could result in considerable morbidity and various critical complications. ⋯ We present here a literature review on the topic of fish bones in otolaryngology with a focus on selection of patients for intervention and on removal techniques. We emphasize that retained fish bones should be approached with caution as their course can at times be unpredictable, as we describe here.

ReviewSystematic evaluation of obstructive sleep apnea websites on the internet.
To determine the quality and comprehensiveness of the websites on the Internet with information directed toward patients with obstructive sleep apnea (OSA). ⋯ There is a heterogeneous mixture of websites with varying quality on the Internet with information regarding OSA. Health care providers should be cognizant of the variety of information available for patients and be prepared to direct patients toward the high-quality information sources.

To determine the prevalence of underlying lower airway inflammatory conditions in children who underwent rigid bronchoscopy (RB) for a suspected foreign body aspiration (FBA) in the tracheobronchial tree and to identify the characteristics of patients who could benefit from a trial of antiasthma treatment prior to undergoing a diagnostic bronchoscopy. ⋯ A conservative approach cannot be justified in suspected asthmatic children with possible FBA, in whom the indications for diagnostic bronchoscopy must be tailored to each patient to ensure a timely diagnosis.

Randomized Controlled Trial Comparative StudyEfficacy and safety of high-concentration adrenaline wicks during functional endoscopic sinus surgery.
Epinephrine is a commonly used vasoconstrictor for instillation or infiltration to limit bleeding and improve the quality of the surgical field in functional endoscopic sinus surgery (FESS). No study to date has shown the efficacy of varying concentrations of adrenaline wicks into the nasal mucosa during FESS. ⋯ High-concentration (4 mg in 20 mL of saline) adrenaline wicks used during FESS significantly improve the quality of the surgical field and decrease blood loss compared to low-concentration (1 mg in 20 mL saline) wicks. Associated hemodynamic changes can be controlled in both groups without significant clinical consequences.
