Aspergillus Sinusitis

Matthew W. Ryan, Bradley F. Marple

Aspergillosis: from diagnosis to prevention > Aspergillus Sinusitis > 779-814

Aspergillus sinusitis has several distinct clinical manifestations, which are determined by the presence or absence of tissue invasion as well as the host’s response to the fungus. Most, but not all fungal sinusitis is caused by Aspergillus organisms. This section on Aspergillus sinusitis utilizes the currently accepted classification scheme for categorising fungal rhinosinusitis. An aspergilloma...

Biological Psychology > 2016 > 118 > C > 44-51

To examine the effect of final exam stress on the concentrations of leukotriene B4 (LTB4) and vascular endothelial growth factor (VEGF) in the upper airways among healthy and asthmatic individuals.Nasal samples were collected from 12 individuals with asthma and 23 healthy controls early and late in a final exam period, and during a low-stress period in the semester. We determined LTB4 and VEGF concentrations...

Allergic Fungal Rhinosinusitis and the Unified Airway: the Role of Antifungal Therapy in AFRS

Matthew W. Ryan, Christopher M. Clark

Current Allergy and Asthma Reports > 2015 > 15 > 12 > 1-6

Allergic fungal sinusitis (AFS) or rhinosinusitis (AFRS) is a form of polypoid chronic rhinosinusitis that is believed to be due to hypersensitivity to fungal antigens. The disease is characterized by type 1 hypersensitivity to fungal allergens, dramatically elevated total serum IgE, accumulation of thick eosinophil-laden mucin with non-invasive fungal hyphae within the paranasal sinuses, nasal polyposis,...

MEMS based AHRS with adaptive bias estimation for high performance rate sensor replacement

Matthew W. Ryan, Geoff Miller

IEEE/ION Position, Location and Navigation Symposium > 214 - 220

2010 IEEE/ION Position, Location and Navigation Symposium - PLANS 2010

Presented is the unique retrofit application of a MEMS based Attitude Heading Reference System (AHRS) into an existing high performance pan and tilt surveillance platform. The platform imaging sensors must provide stable imagery from fixed and moving locations, rejecting external rate disturbances. The quaternion based attitude estimator provides gyro bias estimates that are removed before output...

Rhinosinusitis and Comorbidities

Matthew W. Ryan, Edward G. Brooks

Current Allergy and Asthma Reports > 2010 > 10 > 3 > 188-193

A variety of systemic conditions impact the incidence, severity, prognosis, and treatment approach in patients with chronic rhinosinusitis (CRS). The controversy surrounding the impact of allergic rhinitis on CRS continues, but it is reasonable to consider and treat allergic sources of inflammation in any patient with CRS. CRS is more severe in patients with aspirin sensitivity but improves—at least...

Going to the next level: Health care's evolving expectations for evidence

Bradley F. Marple, Scott P. Stringer, Pete S. Batra, Neil Bhattacharyya, more

Otolaryngology - Head and Neck Surgery > 2009 > 141 > 5 > 551-554

Rhinologic literature has historically relied on lower levels of evidence to make prescriptive recommendations for use of new technology and procedures. However, as the medical profession has moved to embrace the principles of evidence-based medicine, expectations for minimum standards of evidence have risen. The resulting high-quality efficacy outcomes data have become the linchpin of informed decision...

Maxillary sinus melanoma as the presenting feature of Carney complex

Matthew W. Ryan, Samuel Cunningham, Shu-Yuan Xiao

International Journal of Pediatric Otorhinolaryngology > 2008 > 72 > 3 > 405-408

We present a case of a large maxillary sinus tumor in a 6-year-old boy, immunohistologically indistinguishable from a malignant melanoma, that led to the diagnosis of Carney complex. The Carney complex is an autosomal dominant disorder characterized by mucocutaneous pigmented lesions and neoplasia of multiple endocrine glands and is usually due to an inactivating mutation of the gene for the protein...

The effect of saline solutions on nasal patency and mucociliary clearance in rhinosinusitis patients

Garrett Hauptman, Matthew W. Ryan

Otolaryngology - Head and Neck Surgery > 2007 > 137 > 5 > 815-821

To compare the effect of two saline nasal sprays on nasal patency and mucociliary clearance in patients with rhinosinusitis.Randomized double-blind trial.Eighty patients with rhinosinusitis at a tertiary care academic center had nasal patency and mucociliary clearance measured. Each patient was then treated with either physiological or hypertonic saline. Nasal patency and mucociliary clearance measurements...

Asthma and the unified airway

John H. Krouse, Randall W. Brown, Stanley M. Fineman, Joseph K. Han, more

Otolaryngology - Head and Neck Surgery > 2007 > 136 > 5 Supplement > S75-S106

Inflammatory processes of the upper and lower airway commonly co-exist. Patients with upper respiratory illnesses such as allergic rhinitis and acute and chronic rhinosinusitis often present to both otolaryngologists and primary care physicians for treatment of their symptoms of nasal and sinus disease. These patients often have concurrent lower respiratory illnesses such as asthma that may be contributing...

John H. Krouse, Maria C. Veling, Matthew W. Ryan, Harold C. Pillsbury, more

Otolaryngology - Head and Neck Surgery > 2007 > 136 > 5 > 699-706

Asthma is a common comorbid disorder that will be seen by otolaryngologists in their treatment of patients with rhinitis, rhinosinusitis, and otitis media. Among otolaryngologists, however, a diagnosis of asthma is infrequently considered in this patient population. Otolaryngologists, however, may be in an important position to recognize this potential diagnosis and provide treatment or appropriate...
