BACKGROUND Reports from the U.S. suggest increases in the proportion and rate of head and neck injuries in skiers and snowboarders. It is important to determine if the same is true in Canada. METHODS Skiers and snowboarders (< 18 years) presenting to 16 selected emergency departments from 1991 to 1999 were assigned one body region of injury in the following order: i) brain and spine-spinal co...

Because of the possible clinical association between coeliac disease and sarcoidosis, the incidence of humoral sensitivity to dietary proteins was examined in patients with sarcoidosis. Raised concentrations of circulating IgG antibodies to alpha gliadin were found in 41/99 sarcoid patients whereas antibody levels to casein, beta lactoglobulin and ovalbumin were similar to normal controls. Subs...

Background—Despite effective treatment with anticoagulants, 2% to 7% of patients with pulmonary embolism will die as a result of their disease. Methods and Results—We examined in 110 consecutive patients with pulmonary embolism whether plasma brain natriuretic peptide (BNP), a novel marker of (right) ventricular dysfunction, is a predictor of fatal pulmonary embolism. The relationship between B...

ownload kground: Malignant mesothelioma is an aggressive, almost uniformly fatal tumor, primarily caused by re to asbestos. Since the recent discovery that serum mesothelin is a sensitive and highly specific bior for mesothelioma, one of the key issues raised is whether mesothelin levels represent a useful screening r asbestos-exposed at-risk individuals. In this study, soluble mesothelin was d...

PURPOSE To perform a systematic review of the diagnostic value of 64-multislice CT (MSCT) angiography in the detection of coronary artery disease (CAD) when compared to conventional coronary angiography. MATERIALS AND METHODS A search of PUBMED and MEDLINE databases for English literature was performed. Only studies with at least 10 patients comparing 64-slice MSCT angiography with convention...

To test prospectively in hypertensives whether moderate and vigorous exercise produces equivalent reductions in mortality, Cox-proportional hazard analyses were applied to energy expenditure (metabolic equivalents hours/d [METh/d]) in 6973 walkers and 3907 runners who used hypertensive medications at baseline. A total of 1121 died during 10.2-year follow-up: 695 cardiovascular disease (Internat...
