UNLABELLED Many score methods have been created to measure paranasal sinus abnormalities seen under CT scan. Currently, the Lund-Mackay staging system is widely accepted. However, its results may be affected by the development in children. AIM To assess the precision and accuracy of a new tomography score, called "opacification-development ratio". It translates the percentage of sinus area th...

Introduction: The objective components of chronic rhinosinusitis (CRS) diagnosis require confirmatory findings from either diagnostic nasal endoscopy (DNE) or a computed tomography (CT) scan. Chronic affects significant population worldwide, imposing huge toll on the human economy as well quality life. Thus, it is particularly important to define cost-effective and easily available tool for it....

Abstract The implant-supported removable partial dentures should be an alternative to conventional removable partial dentures and implant-supported fixed partial prostheses when the implant’s insertion is confined by bone height and thickness. Placing a single implant in the posterior region would modify the Kennedy Class II configuration to a Kennedy Class III and increase the stability a...

BACKGROUND/AIM Chronic sinusitis is a disease characterized with mucosal inflammation of nasal and paranasal sinuses for at least 12 weeks. In order to assess the extent and severity of inflammatory changes in paranasal sinuses CT score according to Lund-Mackay is the most commonly used. Recent studies show the possibility of existing different subtipes of chronic rhinosinusitis, pointing out t...

Objectives: To determine diagnostic effectiveness of office fiberoptic nasal endoscopy as preliminary examination tool during outpatient clinic examinations of patients with chronic rhinosinusitis (CRS). Patients & Methods: One hundred CRS UAE patients (Group A) and another 100 Egyptian patients (Group B). All patients were evaluated for impact of CRS on their quality of life (QOL) using the Si...

The aim of this prospective study was to evaluate whether cytokine levels in nasal secretions may be clinical parameters of severity of nasal polyposis. Forty nasal polyp patients (20 asthmatic and 20 nonasthmatic) requiring surgical treatment were included. Nasal secretion samples were collected from nasal cavities of all 40 subjects. The levels of T-helper type 1 (Th1) proinflammatory cytokin...

OBJECTIVE Aspirin exacerbated respiratory disease (AERD) is comprised of aspirin/acetylsalicylic acid (ASA) sensitivity, bronchial asthma, and nasal polyposis. Treatment of this condition is challenging and may include topical/systemic steroids, endoscopic sinus surgery, and/or aspirin desensitization. STUDY DESIGN A prospective crossover pilot study (n = 10) was conducted in which patients w...

We prove that there exists a class of crystalline insulators, which we call "fragile Mott insulators," which are not adiabatically connected to any sort of band insulator provided time-reversal and certain point-group symmetries are respected, but which are otherwise unspectacular in that they exhibit no topological order nor any form of fractionalized quasiparticles. Different fragile Mott ins...
