The usefulness of serum troponin levels in evaluating cardiac injury.
The diagnosis and clinical significance of blunt cardiac injury remains controversial. Cardiac troponin I is not found in skeletal muscle and has a high sensitivity for myocardial ischemia or injury. We hypothesized that normal troponin levels 4 to 6 hours postinjury would effectively exclude the diagnosis of cardiac contusion. ⋯ An elevated troponin does not definitively diagnose a clinically significant contusion. However, these patients should be monitored at least for 24 hours. Patients suspicious for cardiac contusions who have normal troponins and no other serious injuries may be safely discharged to go home from the emergency department.

We evaluated clinical factors that are predictive of pelvic X-ray findings. We sought to identify whether routine pelvic films are necessary in blunt trauma and addressed whether removal of these films would minimize cost. We performed a retrospective chart review of 111 patients without pelvic fractures and 108 with pelvic fractures seen at our Level 1 trauma center between August 1998 and September 1999. ⋯ The back and pelvic examinations were significantly associated with X-ray results (P < 0.001), and the potential savings with selective radiography was $168,300.00 per year. We believe that clinical factors identified in our study predict the need for pelvic X-ray. Because removal of these films would minimize cost we recommend the elimination of routine pelvic films for the awake and alert blunt trauma patient.

Case ReportsA continuum between scapulothoracic dissociation and traumatic forequarter amputation: a review of the literature.
Both traumatic forequarter amputation and scapulothoracic dissociation are rare and life-threatening injuries. We present the case of a 31-year old woman who was ejected from a car after a motor vehicle accident and sustained an apparent partial forequarter amputation. ⋯ With both injuries mortality is high and prompt diagnosis and treatment imperative. By viewing scapulothoracic dissociation and forequarter amputation as a continuum faster recognition and appropriate treatment may be implemented for these devastating injuries.

Outcome of perforated necrotizing enterocolitis in the very low-birth weight neonate may be independent of the type of surgical treatment.
Perforated necrotizing enterocolitis (NEC) in the low-birth weight infant is now one of the most common surgical problems encountered in contemporary neonatal intensive care units. However, morbidity and mortality from NEC remain high, and the optimal surgical management of these infants remains controversial. Currently few data exist comparing the factors influencing outcome in very low-birth weight infants with perforated NEC treated by either local drainage or exploration. ⋯ The mean number of comorbidities was greater for drainage than for surgery, and for the same number of comorbidities the probability of survival tended to be greater for those treated with drainage than for those undergoing surgery. Multiple logistic regression analysis identified the total number of comorbidities as affecting outcome rather than treatment choice. This suggests therefore that selection of therapeutic options for the patient requires evaluating all factors that may impact survival rather than applying a single treatment strategy for all patients.

Traumatic injury to the innominate artery is a rare occurrence. A literature review reveals that penetrating wounds account for the overwhelming majority of these injuries. Fewer than 90 cases of innominate artery injury caused by blunt trauma have been documented. ⋯ Both were repaired through a median sternotomy with cervical extension as necessary. Given the present technology of safety restraint devices this injury may occur with greater frequency. A "shoulder strap sign" should prompt a search for more extensive injuries.
