Intravenous leiomyomatosis is a histologically benign smooth-muscle tumor arising from either a uterine myoma or the walls of a uterine vessel with extension into veins. Echocardiographic features of two cases of intravenous leiomyomatosis with extensive spread into the right-sided cardiac chambers and pulmonary arteries are described. ⋯ Distinctive echocardiographic features include 1) elongated mobile masses extending from the veins of the lower body, including inferior vena cava and azygos vein; 2) multiple venous attachments or metastases; and 3) filling of venous vessels and right-heart chambers. Intracardiac leiomyomatosis should be considered in a female patient presenting with an extensive mass in the right-sided cardiac chambers.

Case Reports
The role of catalytic converters in automobile carbon monoxide poisoning: a case report.
Inhaling motor vehicle exhaust fumes is a common method used by people attempting to commit suicide; however, the decreased carbon monoxide concentrations found in the exhaust of late-model automobiles equipped with catalytic converters are changing the clinical presentation of exhaust inhalation.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparative efficacy and safety of albuterol sulfate Spiros inhaler and albuterol metered-dose inhaler in asthma.
To compare the long-term efficacy and safety of albuterol administration using a Spiros Inhalation System (Dura Pharmaceuticals; San Diego, CA) dry powder inhaler (DPI) and albuterol (Ventolin; Glaxo Wellcome; Research Triangle Park, NC) administration using a metered-dose inhaler (MDI) in patients with asthma. ⋯ Both active treatments were superior to the placebo treatment. The Spiros DPI was well tolerated and was as effective as the albuterol MDI in treating patients with moderate asthma.

Randomized Controlled Trial Clinical Trial
A randomized and controlled trial of the effect of treatment aimed at maximizing oxygen delivery in patients with severe sepsis or septic shock.
To evaluate the effects of increased oxygen delivery on mortality and morbidity. ⋯ Treatment aimed at maximizing oxygen delivery in patients with severe sepsis or septic shock does not reduce mortality or morbidity.

To evaluate the relationship between inadequate antimicrobial treatment of infections (both community-acquired and nosocomial infections) and hospital mortality for patients requiring ICU admission. ⋯ Inadequate treatment of infections among patients requiring ICU admission appears to be an important determinant of hospital mortality. These data suggest that clinical efforts aimed at reducing the occurrence of inadequate antimicrobial treatment could improve the outcomes of critically ill patients. Additionally, prior antimicrobial therapy should be recognized as an important risk factor for the administration of inadequate antimicrobial treatment among ICU patients with clinically suspected infections.
