Irrespective of country-specific differences in terminology, language, prevalence and manifestations of this disease, evidence-based, world-wide valid consensus definitions are possible. A global consensus definition of GERD will simplify disease management, make mutual research possible and help in the design of generally valid studies. This will not only help the patient but also the physician and supervisory bodies.

IntroductionAcute 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/MethodsDiagnosis 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. ARS diagnosis and antibiotic prescription rates and frequencies of antibiotic classes were calculated.ResultsEighty-eight percent of patients diagnosed with ARS in 2013 were adults, with a greater rate of antibiotic prescriptions observed among the adults relative to the pediatric patients (1632.9 and 468.6 antibiotic prescriptions per 10,000 inhabitants). Between 2007 and 2013, the ARS diagnosis rate decreased from 596 to 464 diagnoses per 10,000 inhabitants, while the percentage of diagnoses with antibiotic prescriptions at the national level remained stable (87% to 84%). From 2007 to 2013, prescription rates for macrolides decreased from 203.5 to 105.4 prescriptions per 10,000 inhabitants. In 2013, penicillins with extended spectrum were more commonly prescribed compared to macrolides among adult patients (153.5 and 105.4 prescriptions per 10,000 inhabitants, respectively).ConclusionThis study is the first to describe physician antibiotic prescribing practices for treatment of ARS in Canada. Results show that antibiotic treatment for ARS represents an area for implementing antimicrobial stewardship, and through it, managing antibiotic resistance. Further work is required to better understand diagnosing practices and treatment criteria for ARS, and use this information to further assist physicians to limit unnecessary antibiotic prescribing practices.

Compared with the traditional location, measurement of acid reflux 1 cm above the GEJ improved the diagnostic accuracy as well as symptom correlation in EE, but not in NERD patients. Thus, pH monitoring 1 cm above the GEJ for improving the diagnosis of NERD cannot be recommended in clinical practice at this time.
