Myocardial involvement by malignant neoplasm is rare and often not clinically manifested. The diagnosis is usually made only at autopsy. A 71-year-old man with squamous cell lung cancer presented with chest discomfort. ⋯ The echocardiography showed a huge hyperechoic mass located in the posterolateral aspect of the left ventricle with myocardium invasion. Thrombolytic therapy was withheld. In patients with lung cancer, an electrocardiogram representative of acute myocardial infarction can rarely be induced by myocardial involvement with lung cancer.

Sedation with analgesia is frequently required to perform painful or invasive procedures in children. The best medication combination for pediatric sedation with analgesia is yet to be identified. Sixty-four of 243 total sedation with analgesia procedures from January 1994 through August 1995 were randomly chosen for descriptive retrospective review and analysis. ⋯ No episodes of respiratory depression, hypotension, or nausea and vomiting occurred in the fentanyl/propofol group. These results show that fentanyl/propofol was superior to other medications used during this study period for pediatric sedation with analgesia. Prospective comparison of this medication combination with other short-acting agents in patients undergoing both elective and emergency procedures is necessary.

Training programs in bedside ultrasound for emergency physicians often encounter considerable resistance, partly because of concern that the number of radiology-interpreted studies ordered from the ED may decrease. This study attempted to determine the effect of instituting an ED training program in ultrasound on the ordering of formal studies from a department of radiology. ⋯ The number of formal studies significantly increased after institution of the training program, both in terms of absolute numbers (annual mean 181 v 95, P < .001) and as a percentage of all outpatient sonograms ordered at the institution (9.8% v 5.1%, P < .001). Introduction of a teaching program in emergency ultrasound appears to increase utilization of formal ultrasound services, at least during the training period.
