introduction: this study was performed to determine the efficacy of mitomycin c on synechia after fess in ethmoid sinuses in patients admitted in imam-khomeini hospital in 2011 and 2012. methods: in this interventional study, 30 patients with pan rhinosinusitis attending to imam-khomeini hospital in 2011 and 2012 were enrolled and in one side after fess, the mitomycin c and in the other side th...

Background: The purpose of this study was to determine an appropriate period for macrolide antibiotic therapy, and to investigate whether this period could be shorter, for patients with chronicrhino sinusitis (CRS) after functional endoscopic sinus surgery (FESS). Methods: A retrospective analysis of 41 patients undergoing FESS for CRS was performed. All patients underwent pre-operative compute...

BACKGROUND The endoscopically magnified operative field in functional endoscopic sinus surgery (FESS) makes even a small amount of bleeding a potentially significant hindrance. It is thought that irrigation with hot saline during surgery may improve surgical field of view by producing a hemostatic effect. Our objective was to assess the effectiveness of hot saline irrigation (HSI) compared to r...

BACKGROUND Flexible fiberoptic bronchoscopy was performed prior to functional endoscopic sinus surgery (FESS) while under general anesthesia to collect bronchoalveolar lavage fluid (BALF) for lower respiratory tract cultures in patients with cystic fibrosis (CF). METHODS A retrospective chart review was performed on all CF patients who underwent combined FESS and bronchoscopy between January ...

Density Functional Theory (DFT) has been used with an empirically-derived correction for the wavenumbers of vibrational band positions to predict the infrared spectra of several fluorinated esters (FESs). Radiative efficiencies (REs) were then determined using the method of Pinnock et al. and these were used with atmospheric lifetimes from the literature to determine the direct global warming p...

Finding efficient and satisfactory energy storage systems (ESSs) is one of the main concerns in industry. Flywheel system (FESS) most which has lots advantages such as high efficiency, long lifetime, scalability, power density, fast dynamic, deep charging, discharging capability. The above features are necessary for electric vehicles (EVs), railways, renewable systems, microgrids. Also, electri...

BACKGROUND The aetiopathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) is still unknown. The role of atopy and the concept of united airways in such patients are still a matter of debate. In this pilot study we aimed at evaluating the degree of eosinophilic inflammation and the frequency of atopy in a cohort of CRSwNP patients candidate for Functional Endoscopic Sinus Surgery (FE...

<p style='text-indent:20px;'>This paper presents a survey for some recent research on the controllability of nonlinear fractional evolution systems (FESs) in Banach spaces. The prime focus is exact and approximate several types FESs, which include basic with classical initial nonlocal conditions, FESs time delay or impulsive effect. In addition, results via resolvent operator are reviewed...

BACKGROUND There is preliminary evidence that patients with chronic rhinosinusitis (CRS) and comorbid obstructive sleep apnea (OSA) have reduced quality-of-life (QOL) improvements after functional endoscopic sinus surgery (FESS) compared with patients without OSA. The effect of OSA severity on QOL improvement after FESS is unknown. OBJECTIVES To better characterize the QOL improvement after F...
