BACKGROUND Administration of tranexamic acid topically and intravenously has demonstrated effectiveness in decreasing blood loss and transfusion rates. METHODS We randomized 131 patients undergoing primary total knee arthroplasty to receive either intracapsular (69) or intravenous tranexamic acid (62). Postoperative blood loss was calculated using the(More)
PURPOSE The mini-clinical evaluation exercise, or mini-CEX, assesses residents' history and physical examination skills. To date, no study has assessed the validity of the mini-CEX (mCEX) evaluation format. The authors' objective was to determine the reliability and validity of the mCEX evaluation format. METHOD Twenty-three first-year residents at(More)
BACKGROUND Patients with traumatic injuries possess a high risk of developing deep venous thrombosis (DVT), thus the need for appropriate prophylaxis. Patients with head injuries pose a unique challenge due to contraindication to the use of anticoagulation. We sought to determine the incidence of DVT and identify specific risk factors for its development in(More)
BACKGROUND It has been customary to initiate feeding through percutaneous endoscopic gastrostomy (PEG) tubes 24 hours or more after placement of these tubes. Recent changes in practice environment and emphasis on early discharge of hospitalized patients prompted us to evaluate early PEG feeding in a randomized prospective manner. METHODS Forty-one(More)
BACKGROUND Laparoscopic camera navigation (LCN) is vital for the successful performance of laparoscopic operations, yet little time is spent on training. This study aimed to develop an inexpensive LCN simulator, to design a structured curriculum, and to determine the transferability of skills acquired. METHODS In this study, 0 degrees and 30 degrees LCN(More)
Mucormycosis is a highly aggressive fungal infection affecting diabetic, immunocompromised, and, occasionally, healthy patients. This infection is associated with significant mortality. We have reviewed 208 cases in the literature since 1970, 139 of which were presented in sufficient detail to assess prognostic factors, and added data from six of our(More)
BACKGROUND Laparoscopic simulator training translates into improved operative performance. Proficiency-based curricula maximize efficiency by tailoring training to meet the needs of each individual; however, because rates of skill acquisition vary widely, such curricula may be difficult to implement. We hypothesized that psychomotor testing would predict(More)
A significant portion of patients sustaining traumatic brain injury (TBI) take antiplatelet medications (aspirin or clopidogrel), which have been associated with increased morbidity and mortality. In an attempt to alleviate the risk of increased bleeding, platelet transfusion has become standard practice in some institutions. This study was designed to(More)
