Records from 182 cases of tick-borne relapsing fever (TBRF) were reviewed. In confirmed cases, there was febrile illness, and spirochetes were identified on peripheral blood preparations. In probable cases, there were clinical features of TBRF and either the same exposure as a confirmed case or serological (indirect fluorescent antibody test and western(More)
BACKGROUND Efficacy of simulators in teaching central venous catheterization (CVC) in an internal medicine residency program is unknown. OBJECTIVE To determine whether or not learning CVC on simulators is associated with improvement in performance of CVC, knowledge about the procedure, and self-reported confidence. METHODS All consenting first-year(More)
PURPOSE To evaluate the reliability and validity of the Mini-Clinical Evaluation Exercise (mini-CEX) for postgraduate year 4 (PGY-4) internal medicine trainees compared to a high-stakes assessment of clinical competence, the Royal College of Physicians and Surgeons of Canada Comprehensive Examination in Internal Medicine (RCPSC IM examination). METHODS(More)
High-stakes assessment of clinical performance through the use of standardized patients (SPs) is limited by the SP's lack of real physical abnormalities. The authors report on the development and implementation of physical examination stations that combine simulation technology in the form of digitized cardiac auscultation videos with an SP assessment for(More)
We report the case of a 52-year-old male patient with recurrent thrombosis from 'primary antiphospholipid syndrome' who developed renal microangiopathy. Despite anticoagulant therapy with coumadin, serum creatinine progressively increased from 398 to 592 mumol/l and platelets decreased to 43,000. The patient responded to high-dose methylprednisolone and(More)
OBJECTIVE High-stakes assessments of doctors' physical examination skills often employ standardised patients (SPs) who lack physical abnormalities. Simulation technology provides additional opportunities to assess these skills by mimicking physical abnormalities. The current study examined the relationship between internists' cardiac physical examination(More)
Two of the ocular complications of rheumatoid arthritis (RA), necrotizing scleritis and keratolysis, have been associated with poor response to standard ocular therapy, and thus poor ocular outcome. We describe 6 patients with active ocular disease and active RA who failed to respond to disease modifying agents or immunosuppressive therapy and whose ocular(More)
OBJECTIVE Experiences with Clostridium difficile-associated diarrhea (CDAD) were reviewed to determine predictors of severity in patients presenting from the community. METHODS All patients admitted to two hospitals over 4.5 years with a primary diagnosis of CDAD were reviewed. Patients requiring a hospital stay of greater than 14 days, colectomy,(More)
