Several are the causes of cervical masses and among them a spontaneous hemorrhage presents a rare and life-threatening condition. Sometimes hemorrhage develops from a previous silent neck lesion as in the case of an anaplastic thyroid carcinoma associated with bleeding. We present two cases: a 70-year-old woman suffering from enlarging cervical mass causing respiratory distress because of upper...

The airway stents restore patency in the face of luminal compromise from intrinsic and/or extrinsic pathologies. Luminal compromise beyond 50% often leads to debilitating symptoms such as dyspnea. Silicone stents remain the most commonly placed stents worldwide and have been the "gold standard" for the treatment of benign and malignant airway stenoses over the past 20 years. Nevertheless, silic...

S tenosis of the supraglottic larynx and pharynx is an uncommon and difficult condition to treat. The most common etiologies include iatrogenic injury from oropharyngeal and supraglottic surgery, radiation therapy, prolonged intubation, trauma, caustic ingestion, and inflammatory diseases. Presenting symptoms are a function of stenosis severity and can range from dysphagia and dysphonia to pote...

All behaviors require coordinated activation of motoneurons from central command and premotor networks. The genetic identities of premotoneurons providing behaviorally relevant excitation to any pool of respiratory motoneurons remain unknown. Recently, we established in vitro that Dbx1-derived pre-Bötzinger complex neurons are critical for rhythm generation and that a subpopulation serves a pre...

Hemoptysis in patients with lung cancer is not uncommon and sometimes have dangerous consequences. Hemoptysis has been managed with various treatment options other than surgery and medicine, such as endobronchial tamponade, transcatheter arterial embolization and radiation therapy. However, these methods can sometimes be used only temporarily or are not suitable for a patient's condition. We pr...

Treatment with auto-CPAP therapy With the ongoing advancements in technology through the past decade, auto-CPAP has displayed an advantage over fixed pressure CPAP in its ability to treat the patient’s changes in sleep state, sleep position, or longterm changes in the patient’s condition. Several brands of auto-CPAP devices are commercially available, with the common objective of maintaining ai...

Objectives (1) Analyze the relationship between intranasal airflow distribution and subjective nasal patency in healthy and nasal airway obstruction (NAO) cohorts using computational fluid dynamics (CFD). (2) Determine whether intranasal airflow distribution is an important objective measure of airflow sensation that should be considered in future NAO virtual surgery planning. Study Design Cros...

Acute asthma is considered to be a complication of respiratory viral infections. This investigation assessed the effects of rhinovirus 39 (RV-39) infection both on the patency and responsiveness of the lower airways. Subjects with allergic rhinitis (AR; n = 50) and without AR (non-AR; n = 46) were intranasally inoculated with RV-39, and monitored for 8 days in an enclosed environment for change...
