Bath salts intoxication: a case series.

Background: Bath salts commonly contain multiple synthetic drugs, and their toxic effects are largely the same as those seen in patients who have taken large doses of amphetamines. Bath salts can be ingested, smoked, or administered intravenously. Their use is on the rise and is responsible for a large number of emergency department visits.

Constrictive bronchiolitis in soldiers returning from Iraq and Afghanistan.

Background: In this descriptive case series, 80 soldiers from Fort Campbell, Kentucky, with inhalational exposures during service in Iraq and Afghanistan were evaluated for dyspnea on exertion that prevented them from meeting the U.S. Army's standards for physical fitness.

Liberation and animation: strategies to minimize brain dysfunction in critically ill patients.

Acute brain dysfunction, usually manifested as delirium, occurs in up to 80% of critically ill patients. Delirium increases costs of hospitalizations and affects short-term outcomes such as duration of mechanical ventilation, intensive care unit (ICU) length of stay, and the hospital length of stay. Long-term consequences-cognitive impairment and increased risk of death-can be devastating.

Oxidative stress in rats after 60 days of hypergalactosemia or hyperglycemia.

Two of the models used in current diabetes research include the hypergalactosemic rat and the hyperglucosemic, streptozotocin-induced diabetic rat. Few studies, however, have examined the concurrence of these two models regarding the effects of elevated hexoses on biomarkers of oxidative stress. This study compared the activities of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase and the concentrations of glutathione, glutathione disulfide, and thiobarbituric acid reactants (as a measure of lipid peroxidation) in liver, kidney, and heart of Sprague-Dawley rats after 60 days of either a 50% galactose diet or insulin deficiency caused by streptozotocin injection.
