The medical community relies on clinical expertise and published guidelines to assist physicians with choices in empirical therapy for system-based infectious syndromes, such as community-acquired pneumonia and urinary-tract infections (UTIs). From the late 1990s, multidrug-resistant Enterobacteriaceae (mostly Escherichia coli) that produce(More)
BACKGROUND Thoracic ultrasound (EFAST) has shown promise in inferring the presence of post-traumatic pneumothoraces (PTXs) and may have a particular value in identifying occult pneumothoraces (OPTXs) missed by the AP supine chest radiograph (CXR). However, the diagnostic utility of hand-held US has not been previously evaluated in this role. METHODS(More)
INTRODUCTION Severe acute renal failure (sARF) is associated with considerable morbidity, mortality and use of healthcare resources; however, its precise epidemiology and long-term outcomes have not been well described in a non-specified population. METHODS Population-based surveillance was conducted among all adult residents of the Calgary Health Region(More)
Enterobacteriaceae, especially Klebsiella spp. producing extended-spectrum beta-lactamases (ESBLs) such as SHV and TEM types, have been established since the 1980s as a major cause of hospital-acquired infections. Appropriate infection control practices have largely prevented the dissemination of these bacteria within many hospitals, although outbreaks have(More)
INTRODUCTION Although sodium disturbances are common in hospitalised patients, few studies have specifically investigated the epidemiology of sodium disturbances in the intensive care unit (ICU). The objectives of this study were to describe the incidence of ICU-acquired hyponatraemia and hypernatraemia and assess their effects on outcome in the ICU. (More)
option in the management of patients who are at risk of or have respiratory failure in the acute care setting. Over the past two decades, the use of noninvasive positivepressure ventilation and of noninvasive continuous positive airway pressure by mask has in creased tremendously among acutely ill patients. Initial case series and uncontrolled cohort(More)
Enterobacteriaceae producing extended-spectrum beta-lactamases (ESBLs) typically cause nosocomial infections. Previous surveillance in the Calgary Health Region showed that Escherichia coli strains producing ESBLs were common among community patients. During the period (2000 to 2002): 23 of 157 (15%) of the strains were positive for blaCTX-M genes from the(More)
BACKGROUND Reports have suggested that the epidemiological profile of invasive Staphylococcus aureus infections is changing. We sought to describe the epidemiological profile of S. aureus bacteremia and to assess whether the incidence and severity of and the antimicrobial resistance rates associated with this bacteremia are increasing. METHODS(More)
OBJECTIVES Few population-based studies have evaluated pyogenic liver abscess (PLA) in North America. We assessed the incidence of PLA and evaluated predictors of mortality. METHODS We used the Nationwide Inpatient Sample to identify all patients with discharges for PLA (ICD-9 572.0) between 1994 and 2005. Multivariable logistic regression analysis was(More)
