We studied the extent and pattern of increased cardiac troponin T (cTnT) concentrations in 174 hemodialyzed patients. cTnT concentrations were above 0.10 and 0.20 microg/L in 29% and 10% of patients, respectively. In patients without acute coronary disease, the highest value observed was 3.2 microg/L. cTnT increased after dialysis in 10 of 12 patients, with(More)
BACKGROUND Spurious increases in serum troponins, especially troponin T, have been reported in patients with and without acute myocardial syndromes. METHODS We studied 78 autopsied patients without clinical myocardial infarction (MI) and correlated histologic cardiac findings with antemortem serum creatine kinase (CK), its MB isoenzyme (CK-MB), cardiac(More)
BACKGROUND Increased plasma troponin T (cTnT), but not troponin I (cTnI), is frequently observed in end-stage renal failure patients. Although generally considered spurious, we previously reported an associated increased mortality at 12 months. METHODS We studied long-term outcomes in 244 patients on chronic hemodialysis for up to 34 months, correlating(More)
BACKGROUND Numerous agencies have developed clinical practice guidelines for the management of postmenopausal osteoporosis. The study objective was to conduct a systematic assessment of the quality of osteoporosis guidelines produced since 1998. METHODS Guidelines were identified by searching MEDLINE (1998+), the world wide web, known guideline developer(More)
A 51-year-old man developed a large retroperitoneal tumor with liver and lymph node metastases; there was no radiological evidence of pancreatic involvement. Despite the progression of disease, results of laboratory tests, notably serum amylase, were normal except for minor increases in aspartate aminotransferase and gamma-glutamyltransferase and a marked(More)
