Mucocele is a rare complication of chronic rhinosinusitis that typically presents with delayed diagnosis and results in local erosion. We present the case of a symptomatic orbital mucocele arising from contralateral sinus disease that crossed the mid...
The relationship between paranasal sinus pneumatization and chronic rhinosinusitis (CRS) without cystic fibrosis is not well understood. Previous investigations have confirmed sinus hypoplasia in cystic fibrosis (CF) patients. This study compares par...
Here, we present a review of the development of paranasal sinuses and pathologies associated to them, allergic and/or infectious sinusitis, in children. A review of 200 medical records of children and adolescents affected with respiratory disease is...
Chronic rhinosinusitis can be refractory and has detrimental effects not only on symptoms, but also on work absences, work productivity, annual productivity costs, and disease-specific quality of life measures. The pathophysiology of chronic rhinosin...
Background: Cysteinyl leukotrienes (CysLTs) play a crucial role in the pathogenesis of airway remodeling. The use of CysLTs receptor antagonists has been included in the management of asthma and rhinitis. However, despite the action of these compound...
Background: Fibroblasts from nasal polyps (NP) of asthma patients have reduced expression of cyclooxygenase 2 (COX-2) and production of prostaglandin E2 (PGE2). We hypothesized that the reported alterations are due to alterations in the availability...
Cystic fibrosis (CF) is the most frequent congenital lethal disease in Caucasians. Impaired mucociliary clearance causes chronic bacterial rhinosinusitis in up to 62% of patients, and almost all patients exhibit sinonasal pathology in CT scans. Patho...
Chronic rhinosinusitis (CRS) and obstructive sleep apnea (OSA) are both highly prevalent chronic diseases in the United States. Association between culture positivity of CPAP machines and sinus samples has not been studied in patients with both disea...
Eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA) is a systemic small-to-medium-sized vasculitis associated with asthma and eosinophilia. Histologically EGPA presents tissue eosinophilia, necrotizing vasculitis, and granulomatous in...
Background: The paranasal sinuses serve as a reservoir of nitric oxide (NO), contributing to baseline nasal NO (nNO) levels. nNO has also been shown to increase transiently with humming, a response that may be blunted in severe rhinosinusitis. Blunti...
