CONCLUSIONS
The study suggests that cancerous inhibitor of protein phosphatase 2A (CIP2A) expression and eosinophilia associate with chronic rhinosinusitis with nasal polyps with aspirin exacerbated respiratory disease (CRSwNP + AERD). Further studies with a larger sample size are needed to evaluate
Experimental sinusitis in rabbits was induced by a chemical burn of the mucous membrane. Local application of dibunol decreased the intensity of the purulent inflammation in the sinuses and that of perifocal serous inflammation. Serous inflammation of the contralateral sinus was practically absent.
There is increasing evidence supporting the impact of neoosteogenesis in the pathophysiology of chronic rhinosinusitis (CRS), especially in the recalcitrant group of patients. Runt-related transcription factor 2 (RUNX2), a member of the RUNX family, controls osteoblast differentiation BACKGROUND
Current evidence suggests that membrane-tethered mucins could mediate corticosteroid efficacy, interacting with glucocorticoid receptor (GR) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Mucin 4 (MUC4)-tethered mucin is expressed in nasal polyp (NP) epithelial cells
BACKGROUND The aim of this study was to explore the upregulated nuclear factor kappaB (NF-kappaB)/microRNA-155 (miR-155) in regulating inflammatory responses and relapse of chronic rhinosinusitis (CRS) with nasal polyps (NP), which underlies the molecular mechanism of glucocorticoid treatment.
OBJECTIVE
To investigate the histopathologic study of the ethmoid bone in chronic sinusitis (CRS) and the role of bone pathology in the pathogenesis of CRS.
METHODS
Specimens of mucosa of ethmoid sinus with bone were collected during operation from 40 patients with CRS, 25 males and 15 females, aged
BACKGROUND
Osteitis, characterized by bony thickening and remodeling, is often considered a hallmark of recalcitrant rhinosinusitis. However, there is limited literature examining the bone in chronic rhinosinusitis (CRS) pathology. In this study we cultured osteoblasts from bone harvested during
BACKGROUND
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory disease of the upper airways frequently associated with asthma. Bacterial infection is a feature of CRSwNP that can aggravate the disease and the response to glucocorticoid treatment.
OBJECTIVE
We examined whether
Eosinophilic chronic rhinosinusitis (ECRS), a subgroup of chronic rhinosinusitis with nasal polyps, is recognized as a refractory eosinophilic disorder characterized by both upper and lower airway inflammation. In some severe cases, disease control is poor, likely due to local steroid insensitivity.
BACKGROUND
A number of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) are resistant to oral corticosteroids. Mucin 1 (MUC1) shows anti-inflammatory properties, and its cytoplasmic tail (CT) interacts with transcription factors, facilitating their nuclear translocation. Because
OBJECTIVE
To identify genes whose expression is most characteristic of chronic rhinosinusitis and aspirin-sensitive asthma through genome-wide transcriptional profiling of nasal polyp tissue.
METHODS
Prospective, controlled study conducted at a tertiary care institution.
METHODS
Thirty genome-wide
Background: The normal serum concentration of alkaline phosphatase (ALP) in adults over the age of 18 ranges from 37 to 116 U/L, while in pregnant women levels of up to twice that upper limit can still be normal. There have been very few reports of extreme
A thirteen-year-old Dutch warmblooded mare was referred to the Faculty of Veterinary Medicine because of a sinusitis. She was thin with a potbellied appearance. Her coat was dull with long wavy hair. Unilateral (left) purulent nasal discharge was evident. A cbc revealed leucopenia (3.9 G.L.-1) and
Objective:To compare and analyze the incidence, clinical features ,imaging features, the preoperative serum alkalinosis phosphatase (ALP) and recurrence rates of osteoma, ossifying fibroma (OF), and fibrous dysplasia (FD) in sinus and maxillofacial benign fibrosis (FOLS). Method: The 273 cases of
Avian haemolytic Actinobacillus-like organisms have tentatively been named Bisgaard taxon 26. Phenotypic information has been published on 65 strains of this taxon. In the current study, 31 isolates were selected for genotypic characterization. Thirty strains had the same rpoB sequence and only one
