Randomized Controlled Trial Comparative Study Clinical Trial
Empiric monotherapy versus combination therapy of nosocomial pneumonia in trauma patients.
Combination therapy for nosocomial pneumonia with a beta-lactam and aminoglycoside is widely accepted because of synergy and reduction of resistant bacteria. This prospective study of 109 trauma patients (94 blunt, 15 penetrating) with nosocomial pneumonia was performed in consecutive phases. In phase 1, patients were randomized to an anti-pseudomonal third-generation cephalosporin--cefoperazone or ceftazidime. ⋯ We conclude that monotherapy had a higher cure rate than combination therapy for empiric therapy of pneumonia in our trauma patients. Combination therapy failed because of superinfection (primarily MRSA). Emergence of MRSA may be from host overgrowth or plasmid-mediated induction of resistance, possibly caused by gentamicin.

Eight hundred fifty-four consecutive motor vehicle crash (MVC) victims admitted from August 1, 1986, through August 31, 1989, were prospectively assessed including measurement of blood alcohol concentration (BAC). One hundred six in-hospital interviews were conducted on competent consenting drivers > or = 18 years old; 22.9% (n = 22) of those who were BAC tested (n = 96) were positive for alcohol on admission. ⋯ Original BAC(+) drivers were also more likely to report a subsequent MVC in the year following discharge (not statistically significant). There is a need to develop an assessment system to identify high crash-risk drivers and establish rehabilitation programs to reduce crash recidivism.

Comparative Study
A comparison between a Canadian regional trauma unit and an American level I trauma center.
Although there has been recent comparison of the Canadian and American health care systems, the issue of trauma has received little attention. Data were collected on all adult motor vehicle crash (MVC) victims admitted to the Sunnybrook Trauma Unit (CAN), Toronto, Canada, and the R Adams Cowley Shock Trauma Center (USA), Baltimore, Maryland from July 1986 through July 1990. ⋯ The hospital-based cost for an average MVC patient at CAN was significantly less than for an average patient at USA and professional charges were at least five times greater at USA. This study provides some insight into the differences in trauma care between Canada and the United States.

Lateral traumatic dislocation of the radial head occurred in a 9-year-old boy with cubitus varus. Reduction of the dislocation and immobilization of the arm in flexion and supination in a plaster cast for 4 weeks were done and after 6 months the boy returned to school, with no problems in daily living.

Comparative Study
Prospective comparison of diagnostic peritoneal lavage, computed tomographic scanning, and ultrasonography for the diagnosis of blunt abdominal trauma.
From January through December 1990, a prospective study comparing the accuracy of diagnostic peritoneal lavage (DPL), abdominal computed tomographic (CT) scanning, and abdominal ultrasonographic (US) scanning was carried out. Patients with stable vital signs following their initial resuscitation coupled with equivocal physical examination findings received both CT and US scanning. A DPL was then done. ⋯ Problems do exist in identifying isolated small intestinal perforations with ultrasonography. Since more and more trauma centers are using ultrasonography in the emergency department as a screening method in the management of patients with blunt abdominal trauma, it is important to avoid overestimating its capability. Frequent re-evaluation of the patient's condition, repeat ultrasonographic scans, diagnostic peritoneal lavage, and CT scanning are complementary and important in the diagnosis of blunt abdominal trauma.
