OBJECTIVE: To assess counts of α4 and α7 nicotinic acetylcholine receptors in nasal polyps of adults with or without long-term exposure to cigarette tobacco smoke. METHODS: Twenty-two patients with and 22 patients without exposure to cigarette tobacco smoke participated in the study. After endoscopic polypectomy, the fragments of the nasal polyps were analysed by immunohistochemistry. RESULTS: Compared to patients with no exposure, patients with exposure showed higher counts of α4 and α7 nicotinic acetylcholine receptors (t-test, p 0...

The aim of the present study was to investigate the expression of microRNA (miR)-663 and its regulatory effects on the pathogenesis of nasal polyposis in children. Nasal polyp tissue, as well as serum and peripheral blood eosinophils were collected from 35 children diagnosed with nasal polypectomy between August 2013 and August 2015. As a control, the inferior nasal concha, serum and peripheral blood eosinophils were collected from 46 patients with nasal septal deviation complicated by inferior turbinate hypertrophy or patients with simple inferior turbinate hypertrophy who had undergone surgical removal of the inferior nasal concha...

Omalizumab, a monoclonal antibody against IgE, may be effective on nasal polyps, but its use is not currently authorized to treat that disease. We report the cases of three patients who were given omalizumab for asthma after undergoing nasal surgical polypectomy. Although such procedure is frequently followed by polyp recurrence, none of the three patients developed this complication, and in one subject the regression of initial polyp return was registered after starting omalizumab. Our data support the hypothesis that omalizumab may be useful to treat nasal polyposis...

BACKGROUND AND PURPOSE: Esthesioneuroblastoma is a neuroectodermal tumor that commonly arises in the nasal cavity olfactory recess and, when isolated to the intranasal cavity, can be indistinguishable from benign processes. Because lesional aggressiveness requires a more invasive operation for resection than polypectomy, patients with isolated intranasal lesions were studied to define distinguishing CT characteristics. MATERIALS AND METHODS: Patients with intranasal esthesioneuroblastoma and controls without esthesioneuroblastoma with olfactory recess involvement were identified by using a report search tool...

The nasal cavity and paranasal sinuses are covered with ciliated respiratory mucosa of ectodermal origin, known as Schneiderian epithelium, which can give rise to different types of sinonasal carcinomas. A 42-year-old woman with a history of nasal polypectomy 3 years previously presented with nasal obstruction and rhinorrhea. She was found to have a papillary mass involving the left nasal cavity, and the left maxillary and ethmoidal sinuses by radiologic examination. She underwent endonasal resection under the diagnosis of oncocytic papilloma...

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop. Cervical polyps found in 2-5% of cases are of low clinical significance and can cause, although rarely, post coital bleedings. Cervical polyps grow during pregnancy and mucorrhoea. Trans vaginal ultrasound (TVU) provides an excellent diagnostic technique to diagnose the size and the anatomic location of endometrial polyps (EPs)...

Inverted Papilloma (IP) is an uncommon and locally aggressive benign tumour of sinonasal region, which tends to recur after surgical resection. Most tumours are confined to the lateral nasal wall and sinuses, with maxillary sinus being most commonly affected and a male preponderance. It has a known association with in situ and invasive carcinomas with a <10% rate of malignant transformation. Most common association has been seen with squamous cell carcinoma and extremely rare association with adenocarcinoma and small cell carcinoma...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

OBJECTIVES/HYPOTHESIS: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a disease process that is driven, in part, by intrinsic mucosal inflammation. Surgery plus continued medical therapy is commonly elected by medically recalcitrant, symptomatic patients. The objective was to evaluate the prevalence of nasal polyp recurrence up to 18 months after endoscopic sinus surgery (ESS) with congruent continuing medical management. STUDY DESIGN: Prospective, multicenter cohort of adult patients undergoing ESS for medically recalcitrant CRSwNP performed between August 2004 and February 2015...

The nose is an uncommon site for head and neck paraganglioma. The diagnosis is seldom established pre-operatively; its rarity, infrequent functionality and often benign biologic outcome underlie this fact. We present one such case in a 60-year-old man who presented with right nasal obstruction and episodic epistaxis. Rhinoscopy revealed a fleshy polypoid mass arising from the anterior cartilaginous nasal septum. Imaging studies excluded extra-nasal extension. The tumor was highly vascular showing numerous variable sized, mostly thin walled branching blood vessels akin to stag-horn shape simulating a vascular neoplasm...

This article reports a presentation of lacrimal sac rhinosporidiosis and informs the reader of this uncommon but important diagnosis. A 36-year-old man from Pakistan presented with a 3-month history of swelling at the nasal aspect of the left lower lid. This was associated with occasional crepitus and slight localised discomfort, but no epiphora. There was a palpable fullness near the left medial canthus associated with telecanthus but a normal sac washout and normal eye examination otherwise. Previous medical history included an ipsilateral nasal polypectomy and inferior meatal antrostomy around 10 years previously, whilst living in Pakistan...

Patients with cystic fibrosis (CF) are at increased risk of nasal polyps. We present the case of a 17-month-old Caucasian patient with CF who presented with hypertelorism causing cycloplegic astigmatism, right-sided mucoid discharge, snoring and noisy breathing. Imaging suggested bilateral mucoceles in the ethmoid sinuses. Intraoperatively, bilateral soft tissue masses were noted, and both posterior choanae were patent. Polypectomy and bilateral mega-antrostomies were performed. Histological examination revealed inflammatory nasal polyposis typical of CF...

BACKGROUND: Abnormal olfaction is common with chronic rhinosinusitis (CRS) and associates with various measures of sinonasal inflammation. The Brief Smell Identification Test (BSIT) has demonstrated improvements in abnormal olfactory detection following endoscopic sinus surgery (ESS), but olfaction remains understudied using this instrument. Discerning longitudinal, postoperative durability in olfaction is critical for patient counseling. METHODS: Adult participants with medically recalcitrant CRS were prospectively enrolled into a multi-institutional cohort study and observed for 18 months after ESS...

We used computational fluid dynamics to study the airflow characteristics in the ostiomeatal complex/middle turbinate of the human upper airway, where clinically relevant nasal polypoid changes occur (designated Regions A1-A4). We assessed six different flow rates representing one full period of respiration, based on realistic human respiration data, in an anatomically correct numerical model of a patient with a history of polypectomy. The simulation results showed that Regions A1-A4 were not correlated with the local stagnation points where a locally high level of wall pressure was achieved...

BACKGROUND: Chronic rhinosinusitis with nasal polyposis (CRSwNP) in Western countries is characterized by eosinophilia, IgE production, and TH2 cytokine expression. Type 2 innate lymphoid cells from polyps produce IL-5 and IL-13 in response to IL-25 and IL-33, although the relevance of this axis to local mucosal T-cell responses is unknown. OBJECTIVE: We sought to investigate the role of the IL-25/IL-33 axis in local mucosal T-cell responses in patients with CRSwNP...
