introduction: the association between asthma and sinonasal disease has been established for years. as sinonasal disease is one of the factors that exacerbates asthma, effective treatment of this disorder may also improve and stabilize the asthmatic condition. this study examines the outcome of endoscopic sinus surgery (ess) on asthmatic patients with massive nasal polyposis. materials and met...
OBJECTIVES/HYPOTHESIS Patients with a history of sinonasal malignancy can develop chronic rhinosinusitis (CRS) as a consequence of their oncologic treatment. Some patients will fail medical management and require endoscopic sinus surgery (ESS). This study reviews the use of ESS in the management of CRS in patients previously treated for sinonasal malignancy. STUDY DESIGN Retrospective review....
The sinonasal cavities are rare locations for metastases. Metastases to these locations are usually solitary and produce similar symptoms to those of a primary sinonasal tumor. Nasal obstruction and epistaxis are the most frequent symptoms. The maxillary sinus is most frequently involved. The most common primary tumor sites to spread to this region originate in the kidney, breast, thyroid, and ...
INTRODUCTION Sinonasal malignancies are uncommon neoplasms with several histological subtypes. These malignancies have a poor prognosis and, because of the nonspecific nature of the symptoms, most patients are diagnosed late when the disease is already at an advanced stage. Therefore, most sinonasal malignancies tend to be treated with surgery and postoperative radiotherapy. Understanding the i...
OBJECTIVES/HYPOTHESIS To characterize the spectrum, symptoms, progression, and effects of endocrine dysfunction on sinonasal disease in polyostotic fibrous dysplasia (PFD) and McCune-Albright Syndrome (MAS). STUDY DESIGN Retrospective review. METHODS A prospectively followed cohort of subjects with PFD/MAS underwent a comprehensive evaluation that included otolaryngologic and endocrine eval...
BACKGROUND Sinonasal complications are common in children with cystic fibrosis (CF). Generally, those children with persistent symptoms of sinonasal polyposis are referred to an otorhinolaryngologic (ORL) physician for sinus surgery. Several studies have reported differences in clinical characteristics between CF patients with and without sinonasal polyps. OBJECTIVES To predict the presence o...
Sarcoidosis is a chronic systemic disease that rarely manifests within the sinuses or orbit. A 65-yearold female presented with 2 weeks of eye proptosis and forehead pressure. A computed tomography scan revealed frontal sinus opacification. The initial diagnosis of orbital cellulitis secondary to frontal sinus infection was made but symptoms returned after medical therapy. Biopsy of preaponeuro...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
In patients with Cystic Fibrosis and a type III mutation, ivacaftor (Kalydeco(®), Vertex) can increase the opening time of the CFTR channel and improve chloride transport. Research showed significant improvement of lung function and increase in weight following ivacaftor use. However, ivacaftor showed to have adverse events on the sinonasal system as well, such as upper respiratory tract infect...
BACKGROUND Sarcoidosis is a chronic disease process characterized by non-caseating granulomatous inflammation, usually involving the lower respiratory tract. Given the rarity of rhinologic involvement, the objectives of the present study were (1) to describe clinical features, and (2) to review outcomes of rhinologic surgery for sinonasal sarcoidosis. METHODS Retrospective analysis was perfor...
