Background: Trauma is viewed by many as a global problem. The phenomenon of similar outcomes within differing healthcare delivery systems can illuminate the strengths and weaknesses of various trauma systems as well as the effects of these characteristics on patient outcome.
Objectives: To compare and contrast demographic and injury characteristics as well as patient outcomes of two urban/suburban trauma centers, one in Israel and the other in the United States.
Methods: Study data were obtained from the trauma registries of two trauma centers. Demographic variables, injury characteristics and outcomes were compared statistically between registries.
Results: Significant differences between the registries were found in demographic variables (age), injury characteristics (Injury Severity Score and mechanism of injury), and outcome (mortality and length of stay). Age and Injury Severity Score were found to be significant predictors of outcome in both registries. The Glasgow Coma Score was found to contribute to patient outcomes more than the ISS. Differences were found in the relative impact of injury and demographic factors on outcomes between the registries. After including the influence of these factors on patient outcomes, significant differences still remained between the outcomes of the trauma centers.
Conclusions: Despite possible explanations for these differences, true comparisons between centers are problematic.

Background: Previous studies have demonstrated myocardial salvage by basic fibroblast growth factor administration following chronic myocardial ischemia or acute myocardial infarction.
Objectives: To study the effect of bFGF on left ventricular morphometry following coronary occlusion and reperfusion episode in rats.
Methods: bFGF (0.5 mg) or placebo was continuously administered for a period of one week using an implanted osmotic pump. Animals were sacrificed 6 weeks after surgery and myocardial cross-sections were stained with Masson-trichrome and with anti-proliferating cell nuclear antigen antibody.
Results: LV area, LV cavity diameter, LV cavity/wall thickness ratio, and injury size were unchanged compared with control animals. Proliferating endothelial cells were significantly more abundant in injured compared with normal myocardium, but with no differences between animals treated or not treated with bFGF.
Conclusions: One week of systemic bFGF administration following coronary occlusion and reperfusion had no additional effect on LV geometry or cellular proliferation in rats.
