STUDY DESIGN Survival following mechanical ventilation for acute respiratory failure has important implications for medical decision-making and allocation of expensive resources for critical care. PROCEDURE We reviewed a 5-year experience with mechanical ventilation in 383 men with acute respiratory failure and studied the impact of patient age, cause of(More)
BACKGROUND Aortic valve replacement is a common procedure in elderly patients. There has been a great deal of controversy about the risks associated with early mortality. Uncertainty of the risk associated with a small valve continues to remain controversial. This study was designed to identify the risk factors influencing early mortality and establish an(More)
Preoperative autologous blood donation is employed with increasing frequency, particularly in patients undergoing elective orthopedic procedures. While autologous transfusion decreases the incidence of postoperative infections and other complications, the cost-effectiveness of this therapy has not been fully investigated. We constructed a decision analytic(More)
We reviewed the clinical and laboratory characteristics of 34 patients who had classical heatstroke during the Kansas City heat wave of 1980. The patients were elderly, predominantly black, and of low socioeconomic class. Overall mortality was 18%, with 9% of patients exhibiting severe residual neurologic deficit; 73% had full recovery. Patients with coma,(More)
BACKGROUND End-stage renal disease and the need for chronic hemodialysis is an indication for hepatitis B vaccination, but up to half of dialysis patients fail to respond to a 40 microg/dose i.m. three-dose primary series of recombinant hepatitis B vaccine. Only another 10-20% respond to additional boosting doses of vaccine. PATIENTS AND METHODS Since(More)
We report a case of severe bilateral knee avascular necrosis in a HIV-positive man receiving ritonavir and inhaled fluticasone. This case highlights the need for a thorough medication history in patients on ritonavir-based antiretroviral therapy, especially where multiple prescribers are involved in the patient's care.
Stereotactic radiosurgery (SR) is a technology that blends the skill and technology of several disciplines such as neurosurgery, radiation oncology, radiology, engineering, medical physics, and nursing. The improvement of neurological imaging that occurred in the 1970s and 1980s provided diagnosticians with the technical foundation necessary to support(More)
Burns are acute and traumatic clinical conditions that still occur for several different reasons. Patient survival could be compromised by severity as well as depth and extension of the damaged area. On the other hand, functional and aesthetic recovery of the lesion is the main aim when the burn covers less than 30% of total body surface area (TBSA).(More)
