introduction: nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma. aetiology is multifactorial and is mainly...
Nasal polyp causes difficulty in breathing due to blockage of nasal passage. The pathogenesis of nasal polyposis is not known. The primary medical therapy available for nasal polyposis is steroid administration. Antihistamines, decongestants and cromolyn sodium provide little benefit. With this background of nasal polyp pathophysiology and the existing management, a case of nasal polyp was trea...
Background and Aim: Inflammation is relatively a documented pathogenic cause of chronic rhinocynositis and nasal polyps, but the definite causes are still unknown. Among the infective causes, we decided to evaluate Mycoplasma and Chlamydia, the two major pathogens in respiratory tract diseases, as a potential etiologies in nasal polys. Materials and Methods: In a descriptive-analytic cross-...
Antrochoanal polyp is an infrequent nasal mass and is uncommon in elderly people. The case is presented of a 65-year-old man who developed a giant antrochoanal polyp which blocked the right maxillary sinus, nasal cavity, nasopharynx, oropharynx and hypopharynx. Endoscopic removal of the polyp as well as the base of the polyp was performed.
BACKGROUND Staphylococcus aureus (S. aureus) plays an important role in the pathogenesis of severe chronic airway disease, such as nasal polyps. However the mechanisms underlying the initiation of damage and/or invasion of the nasal mucosa by S. aureus are not clearly understood. The aim of this study was to investigate the interaction between S. aureus and herpes simplex virus type 1 (HSV1) in...
In case of no head trauma history and intact immunity, adultonset recurrent bacterial meningitis is scarce. Parameningeal infection the crucial latent cause in adults. Nasal polyp can a variety nasal symptoms, depending on its location size. Chronic sinusitis with tends to have more severe symptoms than those without polyp. We report adult onset third associated inflammatory
OBJECTIVE To determine the pattern of cellular infiltration in nasal polyposis among Malaysian population and to compare the pattern of cellular infiltration in nasal polyposis between Malaysian and other Asian countries. MATERIAL AND METHOD This is retrospective study done on patients diagnosed with nasal polyposis from January 2008 to June 2012 in University Malaya Medical Center. Only the ...
Nasal polyps are benign lesions commonly affecting up to 4% of the population [1]. Some theories considered polyps a consequence of conditions which cause chronic inflammation in the nose and nasal sinuses characterised by stromal oedema and cellular infiltration [2]. While many aspects of nasal polyps had been documented, the initiating cause remained unknown and might be different for differe...
Background/aim: Nasal polyposis is a chronic inflammatory disease affecting the paranasal sinuses and nasal mucosae. It is thought that genetic and molecular mechanisms in inflammatory and apoptotic pathways are the main factors in the etiopathogenesis of nasal polyposis. The aim of this study was to investigate the expression patterns of CD11b, galectin-1, beclin-1, and caspase-3 in nasal poly...
The pathogenetic mechanism of nasal polyps remains unknown, although allergy has been cited as an important factor in the etiology of nasal polyposis. Currently there is no definite histological criterion for differentiation of allergic from inflammatory nasal polyp. However, in a few studies, tissue eosinophil count has been used for this. This study aimed to find out the agreement rate of ski...
