OBJECTIVES Endourologic techniques ranging from balloon dilation to endoincision with electrocautery, cold knife, and lasers have been increasingly used in recent years for the treatment of ureteral strictures. While the long-term results may not be as reliable or as durable as traditional reconstructive surgical techniques, they can be accomplished with(More)
BACKGROUND Among patients with reversible conditions who sustain cardiac arrest, extracorporeal membrane oxygenation (ECMO) may support end organ perfusion while bridging to definitive therapy. METHODS A single center retrospective review (February 2008–September 2013) of adults receiving ECMO for cardiac arrest ≥15 min duration refractory to conventional(More)
BACKGROUND AND PURPOSE The treatment options available for managing bladder calculi include transurethral cystolithotripsy, open cystolithotomy, and shockwave lithotripsy. For larger calculi, transurethral treatment can be time consuming, and the manipulation has the potential to cause urethral injury. Percutaneous suprapubic cystolithotripsy represents(More)
The management of ureteral stones has undergone revolutionary changes in the past 15 years. The parallel advances in extracorporeal shock wave lithotripsy, percutaneous and retrograde endoscopic access to the collecting system, and intracorporeal lithotripsy devices almost completely have supplanted the need for a traditional ureterolithotomy. The merits of(More)
BACKGROUND Renal injury is common after open-heart surgery. Cardiopulmonary bypass contributes to the problem. We compared conventional nonpulsatile perfusion (NP) to biologically variable perfusion (BVP), which uses a computer controller to restore physiological beat-to-beat variability to roller pump flow. We hypothesized BVP would decrease renal injury(More)
Infective endocarditis has many facets and various expressions depending on the site of infection, microorganism, underlying heart lesion, immune status of the host, and remote effects such as emboli, organ dysfunction, and the condition of the host. Diagnosis depends on meticulous clinical examination, blood cultures results, and echocardiographic(More)
PURPOSE Blastomyces dermatitidis is a dimorphic fungus endemic to North America capable of causing fatal respiratory failure. Acute respiratory distress syndrome (ARDS) complicates up to 10% of pulmonary blastomycosis in hospitalized patients and carries a mortality of 50-90%. This report describes the clinical course of four consecutive patients with(More)
INTRODUCTION In a landmark 2013 decision, the Supreme Court of Canada (SCC) ruled that the withdrawal of life support in certain circumstances is a treatment requiring patient or substitute decision maker (SDM) consent. How intensive care unit (ICU) physicians perceive this ruling is unknown. OBJECTIVES To determine physician knowledge of and attitudes(More)
BACKGROUND Health care providers' perceptions regarding appropriateness in end-of-life treatments have been widely studied. While nurses and physicians believe that rationing and other cost-related practices sometimes occur in the intensive care unit (ICU), they allege that treatment is often excessive. OBJECTIVE To prospectively determine the incidence(More)
High-risk angioplasty has been defined as an intervention on an unprotected left main (LM) coronary artery or "last patent coronary conduit" in the context of moderate to severe left ventricular (LV) dysfunction. We report a case of a patient with severe LV dysfunction, severe aortic valve stenosis, and an occluded right coronary artery requiring elective(More)
