OBJECTIVES a) To evaluate the predictive ability of different creatinine clearance methods as compared with the criterion standard, inulin clearance; and b) to determine which of the predictive methods yields the most accurate estimation of creatinine clearance. DESIGN Prospective study. SETTING Medical intensive care unit (ICU) of a(More)
OBJECTIVE To characterize the disposition of total and free serum digoxin following the administration of digoxin Fab antibody in patients with varying degrees of renal function. DESIGN Observational study of pharmacokinetics and pharmacodynamics. SETTING Critical care and telemetry units of two university-affiliated teaching institutions, Hartford(More)
A dorsal pedicled buccal musculomucosal flap was developed to reconstruct medium-sized intraoral defects, too large for primary closure if major functional and esthetic impairment is to be avoided. Although free flaps, axial, or perforator flaps are excellent in large defects, they may not provide mucosal sensitivity, motility, volume, and texture to(More)
OBJECTIVE The aim of this preliminary investigation was to evaluate the use of aminoglycoside serum concentrations as a surrogate measure of the glomerular filtration rate (GFR) in comparison with other measured and empiric methods against inulin, the criterion standard measure of GFR. DESIGN A consecutive sample of all eligible patients. SETTING An(More)
BACKGROUND Endoscopic insertion of biliary stents is a useful treatment for obstructive jaundice resulting from unresectable tumors of the pancreas and biliary tree. The main drawback is the recurrence of jaundice due to clogging. The aim of this study was to establish an experimental model of polyethylene stent clogging in large white pigs. METHODS A(More)
Digoxin intoxication occurs frequently and may require treatment with digoxin-specific Fab therapy. Little is known, however, regarding the biological fate of this compound. Pharmacokinetic studies have not been performed in healthy volunteers, but there are limited kinetic data from patients who have received therapy for the treatment of digoxin toxicity.(More)
The objective of this study was to assess the utility of bioelectrical impedance analysis (BIA) in determining nutritional status in critically ill patients in the intensive care unit (ICU). Data were collected prospectively in 33 mechanically ventilated medical and surgical ICU patients requiring nutrition as part of their care. BIA, with subsequent(More)
Digoxin fab antibody therapy is known to interfere with digoxin immunoassays causing spurious serum digoxin concentrations. The reliability and precision of three digoxin immunoassays--Baxter Dade Stratus (BDS), Syva affinity column enzyme-mediated immunoassay (EMIT), and the reference assay Abbott TDx fluorescence polarization immunoassay following(More)
Digoxin and digoxin immune Fab, its antidote, are eliminated renally. However, the disposition of Fab in severe kidney disease is poorly described. Therefore, the disposition of Fab and its relationship to total and free digoxin were studied in five digoxin-toxic patients with end-stage renal disease (n = 4) or severe renal dysfunction (n = 1) with a mean(More)
Ticlopidine is a new prototype antiplatelet drug chemically unrelated to currently available agents. It causes an alteration in platelet membrane reactivity to a variety of aggregating stimuli and a marked prolongation of bleeding time, the mechanism of which remains unclear. Two major phase III multicenter trials, the ticlopidine-aspirin stroke study(More)
