Objective The purpose of this study was to define the period of time after which delays in management incurred by investigations cause increased morbidity and mortality. The outcome study is intended to correlate time with death from esophageal causes, overall complications, esophageal related complications, and surgical intensive care unit length of stay. Methods This was a retrospective multicenter study involving 34 trauma centers in the United States, under the auspices of the American Association for the Surgery of Trauma Multi-institutional Trials Committee over a span of 10.5 years. Patients surviving to reach the operating room (OR) were divided into two groups: those that underwent diagnostic studies to identify their injuries (preoperative evaluation group) and those that went immediately to the OR (no preoperative evaluation group). Statistical methods included Fisher's exact test, Student's t test, and logistic regression analysis. Results The study involved 405 patients: 355 male patients (86.5%) and 50 female patients (13.5%). The mean Revised Trauma Score was 6.3, the mean Injury Severity Score was 28, and the mean time interval to the OR was 6.5 hours. There were associated injuries in 356 patients (88%), and an overall complication rate of 53.5%. Overall mortality was 78 of 405 (19%). Three hundred forty-six patients survived to reach the OR: 171 in the preoperative evaluation group and 175 in the no preoperative evaluation group. No statistically significant differences were noted in the two groups in the following parameters: number of patients, age, Injury Severity Score, admission blood pressure, anatomic location of injury (cervical or thoracic), surgical management (primary repair, resection and anastomosis, resection and diversion, flaps), number of associated injuries, and mortality. Average length of time to the OR was 13 hours in the preoperative evaluation group versus 1 hour in the no preoperative evaluation group (p < 0.001). Overall complications occurred in 134 in the preoperative evaluation group versus 87 in the no preoperative evaluation group (p < 0.001), and 74 (41%) esophageal related complications occurred in the preoperative evaluation group versus 32 (19%) in the no preoperative evaluation group (p = 0.003). Mean surgical intensive care unit length of stay was 11 days in the preoperative evaluation group versus 7 days in the no preoperative evaluation group (p = 0.012). Logistic regression analysis identified as independent risk factors for the development of esophageal related complications included time delays in preoperative evaluation (odds ratio, 3.13), American Association for the Surgery of Trauma Organ Injury Scale grade >2 (odds ratio, 2.62), and resection and diversion (odds ratio, 4.47). Conclusion Esophageal injuries carry a high morbidity and mortality. Increased esophageal related morbidity occurs with the diagnostic workup and its inherent delay in operative repair of these injuries. For centers practicing selective management of penetrating neck injuries and transmediastinal gunshot wounds, rapid diagnosis and definitive repair should be made a high priority.
Periprosthetic breast capsules composed of fibrotic collagenous material with increased collagen production are not dissimilar to other fibrotic conditions occurring in other organs. Fibrosis in the lung, liver, kidney, and skin has been associated with overproduction of the fibrogenic isoforms of transforming growth factor beta (TGF-beta1 and TGF-beta2). If periprosthetic breast capsules contained high levels of these cytokines, possibly new treatment approaches for capsular contraction could be proposed. Breast implant capsules of 35 patients harvested at the time of explantation were examined using indirect immunohistochemistry. Staining intensity for TGF-beta1 and TGF-beta2 was measured in all specimens. Immunohistochemical staining for TGF-beta1 and TGF-beta2 revealed that these two cytokines were present in all capsules analyzed. Minimal TGF-beta1 and TGF-beta2 were found in normal breast tissue. Levels of control vs. TGF-beta1 and control vs. TGF-beta2 were significant (p = 0.004 and p < 0.001 respectively). The presence of TGF-beta isoforms that are known to be fibrogenic may suggest new therapeutic approaches, which are being investigated for other fibrotic conditions.
The vast majority of hospitals in the United States today are led by nonphysicians. This is in sharp contrast to the turn of the 20th century, when over a third of the hospitals in the United States were physician led. As the pendulum swings back from lay leader to clinician leader, there is a strong and appropriate opportunity for physicians to reinsert themselves into a leadership role. In fact, the time has perhaps never been more appropriate than today. In a health care system that is complex, troubled, and challenging, the physician CEO brings a unique set of skills to the business of medicine. The successful physician leader, however, must understand the business of medicine as well as or better than he or she understands the practice of medicine. Training, developing, and equipping our future physician leaders with the necessary skill sets will be one of medicines' many challenges as it expands into the 21st century.
A prospective clinical study was undertaken in 50 consecutive patients suffering from severe traumatic shock to evaluate the clinical efficacy of a set for rapid administration of solutions (RSAS), which allows for rapid infusion and simultaneous warming of blood and fluids. The mechanism of injury was blunt in 37 patients and penetrating in 13. Admission trauma score averaged 7.5, and the injury severity score averaged 46. Average preresuscitation systolic blood pressure was 71 mmHg, pulse was 105 beats/minute, and temperature was 34.3 degrees C. Initial resuscitation was with the RSAS, and total fluid infused in the first twenty-four hours averaged 4,632 mL of blood, 1,914 mL of blood products, and 11,248 mL of crystalloid. The average postresuscitation systolic blood pressure was 120 mmHg, pulse was 96 beats/minute, and temperature averaged 34.9 degrees C. Survival at twenty-four hours was 29/50 (58%). There were no local complications of RSAS use and no evidence of infusion-related coagulopathy. The RSAS provided an effective and safe way to infuse large volumes of blood and fluid at body temperature.
