Motor vehicle travel is the primary means of transportation in the United States, providing freedom in travel and enterprise for many people. Motor vehicle crashes are the leading cause of death for the young and contribute to a high degree of morbidity and mortality for all ages. ⋯ Motor vehicle crash injury prevention is developing as a focused discipline to implement proven interventions involving technology and behavior known to prevent or reduce the severity of motor vehicle crash injury. Emergency physicians have an important role in advocating motor vehicle safety and injury prevention, both in the emergency department and within the community.

In 1996, almost 11 million lacerations were treated in emergency departments throughout the United States. Although most lacerations heal without sequelae regardless of management, mismanagement may result in wound infections, prolonged convalescence, unsightly and dysfunctional scars, and, rarely, mortality. ⋯ Recent US Food and Drug Administration approval of tissue adhesives has significantly expanded clinicians' wound closure options and improved patient care. We review the general principles of wound care and expand on the use of tissue adhesives for laceration repair.

We conducted a 5-year time study analysis of emergency department patient care efficiency. Our specific aims were (1) to calculate the main ED patient care time intervals to identify areas of inefficiency, (2) to measure the effect of ED and inpatient bed availability on patient flow, (3) to quantitatively assess the effects of administrative interventions aimed at improving efficiency, and (4) to evaluate the relationship between waiting times to see a physician and the number of patients who leave without being seen (LWBS) by a physician. ⋯ Time studies are an effective method of identifying areas of patient care delay. In our ED, targeted administrative interventions apparently reduced the total ED LOS and improved overall efficiency. Despite initial decreases in ED LOS, efficiency appeared to be adversely affected by reductions in nursing and physician staffing and increases in our patient census. The strength of the relationship between waiting times to see a physician and the number of LWBS patients suggests that decreasing waiting times may reduce the number of LWBS patients.

The most common extraintestinal manifestation of Entamoeba histolytica, the agent of amebiasis, is a hepatic abscess. This infection is common throughout the world and can be associated with life-threatening consequences. Given the often nonspecific nature of the complaints related to an amebic abscess, a retrospective review of patients with confirmed disease was done to recognize the most common patterns of presentation. ⋯ Patients with amebic liver abscess do present to EDs in the southwestern United States, especially in areas with a high immigrant population from endemic areas. Patients with complaints of fever and right upper quadrant abdominal pain, especially men of Hispanic origin, warrant a high degree of vigilance. Whereas most laboratory studies are unhelpful, the diagnosis can often be made in the ED by means of a bedside ultrasonographic test. Treatment should be initiated with metronidazole with disposition to an inpatient medical service.

To determine the sensitivity and specificity of the urine ketone dip test as a screening test for ketonemia in hyperglycemic patients and to compare the performance of the urine ketone dip test with the anion gap and serum bicarbonate level. ⋯ The urine ketone dip test has high sensitivity for detecting DKA and a high negative predictive value for excluding DKA in hyperglycemic patients with diabetes with any symptoms of illness. The urine ketone dip test is a better screening test for DKA and DK than the anion gap or serum bicarbonate.
