CT angiography in penetrating neck trauma reduces the need for operative neck exploration.
The evaluation of penetrating neck injury has evolved dramatically from mandatory operative exploration of Zone II injuries that penetrate the platysma to selective management based on physical examination and adjunctive studies. More recently, CT angiography has emerged as an efficient, noninvasive method of evaluating penetrating neck injury. We retrospectively reviewed our experience over 10 years with the management of penetrating neck injury. ⋯ Of the 34 patients in CTA, 4 (12%) also underwent angiography and 4 (12%) received a contrast esophagram. Of the 64 patients in nCTA who did not undergo a neck exploration, 19 (29%) underwent angiography, and 17 (26%) received a contrast esophagram. The use of CT angiogram increased over time with a concomitant decrease in the rate of neck explorations.

The effect of older blood on mortality, need for ICU care, and the length of ICU stay after major trauma.
The purpose of this study was to determine if the quantity and age of blood is an independent risk factor for in-hospital mortality, need for intensive care unit (ICU) care, and an increased length of stay in the ICU. This was a retrospective cohort study performed at a level I trauma center between 2001 and 2003. Consecutive trauma patients who received at least 1 unit of packed red blood cells (PRBCs) were included. ⋯ The quantity of aged blood is an independent risk factor for length of ICU care. This may be a proxy indicator for multiple organ failure. Further research is required to define which patients may benefit from newer blood.

Predictors of morbidity and mortality in patients with traumatic duodenal injuries.
The aim of our study is to determine factors that predict morbidity and mortality in patients with traumatic duodenal injury (DI). A retrospective review from July 1996 to March 2003 identified 52 patients admitted to our trauma center (age 24.4 +/- 2.1 years, ISS = 18.8 +/- 1.76). The mortality rate for patients with duodenal injury was 15.4 per cent (n = 8). ⋯ Univariate analysis demonstrated that nonsurvivors were older, more, hypotensive in the emergency department, had a more negative initial base deficit, had a lower initial arterial pH, and had a higher Injury Severity Score. Nonsurvivors were also more likely to have an associated inferior vena cava (IVC) injury. Multivariate regression analysis revealed age, initial lowest pH, and Glasgow Coma Score to be independent predictors of mortality, suggesting that the physiologic presentation of the patient is the most important factor in predicting mortality in patients with traumatic DIs.

Magnetic resonance imaging (MRI) has been shown to detect occult invasive breast cancers with a sensitivity of 97 per cent to 100 per cent. Mammography and ultrasonography does not accurately assess the extent of ductal carcinoma in situ (DCIS), which results in a high reoperation rate. Breast MRI can improve the surgical planning in women with DCIS, improving the adequacy of initial treatment while reducing reoperation. ⋯ MRI changed the surgical management to more appropriate therapy in 15 per cent of patients avoiding additional surgery, while 11 per cent underwent negative surgical interventions. Breast MRI is a sensitive diagnostic imaging tool in patients with DCIS. However, any suspicious finding should be biopsied before a definitive operation is planned.

Is repeated head computed tomography necessary for traumatic intracranial hemorrhage?
This study was performed to determine the need for repeat head computed tomography (CT) in patients with blunt traumatic intracranial hemorrhage (ICH) who were initially treated nonoperatively and to determine which factors predicted observation failure or success. A total of 1,462 patients were admitted to our level II trauma center for treatment of head injury. Seventeen per cent (255/1,462) were diagnosed with ICH on initial head CT. ⋯ Multivariate analysis revealed the following significant admission risk factors were associated with a need for repeat head CT indicating the need for craniotomy: treatment with anticoagulation and/or antiplatelet medications, elevated prothrombin time (PT), and age greater than 70 years. In patients with blunt traumatic intracranial hemorrhage initially observed, there is little utility of repeated head CT in the absence of deteriorating neurologic status. The only admission risk factors for a repeat CT indicating the need for craniotomy were advanced age and coagulopathy.
