    OBJECTIVES/HYPOTHESIS: The aim of this study was to evaluate the associations between nasal nitric oxide and nasal symptoms, sinus opacification, and markers of allergic inflammation in allergic and in nonallergic rhinitis while taking into account the effect of sinus obstruction.

    STUDY DESIGN: We studied 175 young adult subjects divided into three groups: 1) allergic rhinitis, 2) nonallergic rhinitis, and 3) controls.

    METHODS: We measured nasal nitric oxide using the breath-holding ...

    BACKGROUND: IL-25 can function as an early signal for the respiratory type 2 response characteristic of allergic asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). In the mouse gut, tuft cells are the epithelial source of IL-25. However, the source of human airway epithelial IL-25 has remained elusive.

    OBJECTIVE: In this study we sought to determine whether the solitary chemosensory cell (SCC) is the predominant source of IL-25 in the sinonasal epithelium.

    METHOD: Flow ...

    Bitter taste receptors (taste family 2 bitter receptor proteins; T2Rs), discovered in many tissues outside the tongue, have recently become potential therapeutic targets. We have shown previously that airway epithelial cells express several T2Rs that activate innate immune responses that may be important for treatment of airway diseases such as chronic rhinosinusitis. It is imperative to more clearly understand what compounds activate airway T2Rs as well as their full range of functions. ...

    OBJECTIVES: Encephaloceles usually involve herniation of frontal lobe tissue through an anterior cranial fossa defect into the ethmoid sinus or nasal cavity. Encephaloceles can also result from temporal lobe herniation through a middle fossa defect into the sphenoid sinus. Within the sphenoid, encephaloceles are thought to occur most commonly in the central or midline aspect of the sinus. Lateral sphenoid encephaloceles, especially within the lateral aspect of the sphenoid sinus when the ...

    BACKGROUND: The development of chronic rhinosinusitis, a mucocele, or persistent headaches is a common indication for the removal of a frontal sinus osteoma. The best surgical approach to ensure complete and safe removal of the lesion is less clearcut. The advent of specialized frontal sinus instruments, angled endoscopes, and surgical navigational systems has made removal of frontal sinus osteomas possible through an endoscopic approach. The aim of this study is to review our recent ...

    Mucociliary clearance (MCC) is the primary physical airway defense against inhaled pathogens and particulates. MCC depends on both proper fluid/mucus homeostasis and epithelial ciliary beating. Vasoactive intestinal peptide (VIP) is a neurotransmitter expressed in the sinonasal epithelium that is up-regulated in allergy. However, the effects of VIP on human sinonasal physiology are unknown, as are VIP's interactions with histamine, a major regulator of allergic disease. We imaged ciliary ...

    In chronic sinusitis, culture-directed antibiotics are often recommended as a cornerstone of treatment. The significance of Gram-negative rods (GNRs), coagulase-negative Staphylococci (SCN), and Staphylococcus aureus has been controversial. In an effort to determine host factors which correlate with culture results, 507 endoscopically-guided cultures are reviewed from 265 patients. A history of asthma, allergic rhinitis, prior sinus surgery, and the concurrent use of antibiotics, ...

    Chronic rhinosinusitis has a significant impact on patient quality of life, creates billions of dollars of annual healthcare costs, and accounts for ∼20% of adult antibiotic prescriptions in the United States. Because of the rise of resistant microorganisms, there is a critical need to better understand how to stimulate and/or enhance innate immune responses as a therapeutic modality to treat respiratory infections. We recently identified bitter taste receptors (taste family type 2 ...

    Innate and adaptive defense mechanisms protect the respiratory system from attack by microbes. Here, we present evidence that the bitter taste receptor T2R38 regulates the mucosal innate defense of the human upper airway. Utilizing immunofluorescent and live cell imaging techniques in polarized primary human sinonasal cells, we demonstrate that T2R38 is expressed in human upper respiratory epithelium and is activated in response to acyl-homoserine lactone quorum-sensing molecules ...

    BACKGROUND: We recently demonstrated the bitter taste receptor T2R38 upregulates sinonasal mucosal innate defense in response to gram-negative quorum-sensing molecules through increased nitric oxide production and mucociliary clearance. T2R38 was initially identified in the quest to understand the variability in bitter taste perception to the compound phenylthiocarbamide (PTC) and demonstrated to have polymorphisms generating diplotypes dividing people into PTC supertasters, ...

    BACKGROUND: Recently, biofilms have been implicated in the pathogenesis of recalcitrant chronic rhinosinusitis (CRS). We sought to determine the prevalence of biofilm-forming cultures obtained from patients with CRS and clinical factors that may contribute to biofilm formation.

    METHODS: Endoscopically guided sinonasal cultures were obtained in duplicate from CRS patients with evidence of mucopurulence. Bacterial swabs were sent for microbiological characterization and were simultaneously ...

    Sinus puncture and aspiration is an invasive procedure that hinders patient enrollment in studies of acute bacterial maxillary sinusitis (ABMS). Pain and minor bleeding also limit its potential diagnostic utility in clinical practice. Cultures obtained by rigid nasal endoscopy were compared with those from sinus puncture and aspiration in 53 patients with ABMS; 46 patients were assessable. Considering recovery of Haemophilus influenzae, Moraxella catarrhalis, or Streptococcus pneumoniae ...

    Acoustic rhinometry is a recently developed method for the objective assessment of nasal patency. In this study, acoustic rhinometry was used to measure changes in nasal cavity dimensions in the immediate response to nasal allergen challenge in eight pollen-sensitive subjects. Acoustic rhinometric changes were compared with subjective symptoms, as well as histamine in nasal secretions, cytology of nasal mucosal scrapings, and changes in olfactory function. A significantly greater ...
