It is increasingly recognized that chronic rhinosinusitis (CRS) comprises a spectrum of different diseases with distinct clinical presentations and pathogenic mechanisms. Defining the distinct phenotypes and endotypes of CRS impacts prognosis and most importantly is necessary as the basis for making therapeutic decisions. The need for individualized defining of pathogenic mechanisms prior to initiating therapy extends to virtually all therapeutic considerations. This is clearly crucial with antibiotics where, barring an influence from their off-target anti-inflammatory pharmacological effects, an understanding of the role of individual biome predicts likelihood of therapeutic benefit...

Chronic rhinosinusitis is an inflammatory disease of the paranasal sinuses that occurs in 1% to 5% of the U.S. POPULATION: It may significantly decrease quality of life. Chronic rhinosinusitis is defined by the presence of at least two out of four cardinal symptoms (i.e., facial pain/pressure, hyposmia/anosmia, nasal drainage, and nasal obstruction) for at least 12 consecutive weeks, in addition to objective evidence. Objective evidence of chronic rhinosinusitis may be obtained on physical examination (anterior rhinoscopy, endoscopy) or radiography, preferably from sinus computed tomography...

BACKGROUND: Functional endoscopic sinus surgery (FESS) is an effective treatment for chronic rhinosinusitis (CRS). Postoperative management strategies after FESS often vary from surgeon to surgeon. Recent data suggests that nasal saline irrigation following FESS is almost universally recommended; however, patient adherence has not been formally evaluated. The purpose of this study is to evaluate postoperative nasal irrigation practices and its effects on short-term outcomes in post-FESS patients...

Introduction:Pseudomonas aeruginosa infections are prevalent amongst chronic rhinosinusitis (CRS) sufferers. Many P. aeruginosa strains form biofilms, leading to treatment failure. Lytic bacteriophages (phages) are viruses that infect, replicate within, and lyse bacteria, causing bacterial death. Aim: To assess the activity of a phage cocktail in eradicating biofilms of ex vivo P.aeruginosa isolates from CRS patients. Methods: P. aeruginosa isolates from CRS patients with and without cystic fibrosis (CF) across three continents were multi-locus sequence typed and tested for antibiotic resistance...

A 4-year-old cocker spaniel, male, of 12kg body weight was presented because of the onset of polyuria or polydipsia. From the first months of its life, the dog had exhibited constant serous to mucopurulent nasal discharge, productive cough, sneezing, reverse sneezing, otitis, and recurrent episodes of fever. The respiratory signs had been treated several times with antibiotics, without ever achieving a complete resolution. Clinical examination revealed normal rectal temperature (38.3°C), increased respiratory rate (40breaths/min), a copious mucous nasal discharge and right deviation of the heart apex beat (ictus cordis)...

The main solution to the global antibiotic resistance crisis is reducing the volume of antibiotic use in medicine, agriculture and the environment. However there is also a pressing need for novel antimicrobials. Despite much rhetoric, there are few entirely novel agents in development. One such therapy to reach clinical use is an agent using Reactive Oxygen Species (ROS), oxygen radicals, as an antimicrobial mechanism. ROS can be delivered to the site of infection in various formats. ROS is highly antimicrobial against Gram positive and negative bacteria, viruses and fungi...

Chronic rhinosinusitis (CRS) is an inflammatory sinonasal condition with multiple etiologic factors that is associated with a vast economic cost. Treatment is most frequently pharmacologic and has centered on agents that ameliorate inflammation, decrease bacterial or pathogen load, and facilitate egress of mucus or purulence from the sinonasal cavity. Nasal saline irrigations, topical nasal steroids, certain antibiotics, and systemic steroids have shown some efficacy in the management of CRS. Recently, biologic therapeutics that target specific inflammatory pathways associated with subsets of CRS have been developed and evaluated...

OBJECTIVES: Antimicrobial resistance has become a global burden for which inappropriate antimicrobial use is an important contributing factor. Any decisions on the selection of antibiotics use should consider their effects on antimicrobial resistance. The objective of this study was to assess the extent to which antibiotic prescribing guidelines have considered resistance patterns when making recommendations for five highly prevalent infectious syndromes. DESIGN: We used Medline searches complemented with extensive use of Web engine to identify guidelines on empirical treatment of community-acquired pneumonia, urinary tract infections, acute otitis media, rhinosinusitis and pharyngitis...

INTRODUCTION: Acute rhinosinusitis (ARS) is a respiratory disease commonly caused by viral infections. Physicians regularly prescribe antibiotics despite bacterial etiologies being uncommon. This is of concern, as this use adds to the selection pressure for resistance. Here we present the descriptive epidemiology of acute rhinosinusitis and corresponding antibiotic prescribing practices by Canadian outpatient physicians from 2007-2013. MATERIALS/METHODS: Diagnosis and antibiotic prescription data for ARS were extracted from the Canadian Disease and Therapeutic Index for 2007 to 2013, and population data were acquired from Statistics Canada...

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses...
