The fire-safe cigarette: a burn prevention tool.

Cigarettes are the most common ignition source for fatal house fires, which cause approximately 29% of the fire deaths in the United States. A common scenario is the delayed ignition of a sofa, chair, or mattress by a lit cigarette that is forgotten or dropped by a smoker whose alertness is impaired by alcohol or medication. Cigarettes are designed to continue burning when left unattended.

The effect of medical insurance coverage on the obtainment of pressure garments.

Pressure garments are used to alter the appearance of immature burn scars. These garments are costly, and delays in obtaining them are frequent. The purpose of the study was to determine the nature of the delays in the obtainment of pressure garments and to examine the role that the payer plays in these delays.

Efficacy of enhanced external counterpulsation in the treatment of angina pectoris.

Eighteen patients with chronic angina despite surgical and medical therapy were treated with an improved system of enhanced external counterpulsation (EECP) (1 hour daily for a total of 36 hours). Patients underwent a baseline treadmill thallium-201 stress test. After EECP treatment, a thallium stress test was repeated for the same exercise duration.

Thallium-201 for assessment of myocardial viability: quantitative comparison of 24-hour redistribution imaging with imaging after reinjection at rest.

Redistribution thallium-201 imaging 2 to 4 h after exercise may be incomplete and therefore may be inadequate to fully assess myocardial variability. Late redistribution imaging 24 h after exercise has been proposed to overcome this limitation of thallium stress imaging. However, because of poor count density the image quality on these studies is often suboptimal.

Validation of continuous radionuclide left ventricular functioning monitoring in detecting silent myocardial ischemia during balloon angioplasty of the left anterior descending coronary artery.

Silent myocardial ischemia has been inferred from transient ST-segment depression during continuous electrocardiographic monitoring. Recently, continuous ambulatory monitoring of left ventricular (LV) function using a radionuclide technique (VEST) has demonstrated episodes of significant silent LV dysfunction in the absence of electrocardiographic changes. To validate the demonstration of silent LV dysfunction with this technique, 12 men were studied during percutaneous transluminal coronary angioplasty.
