The aim of this study is to compare the radiologic diagnostic performance of arterial phase, portal phase and combined phase computed tomography (CT) for traumatic abdominal injury. In addition, this study is attempted to decrease lifetime attributable risks (LARs) of cancer due to radiation exposure by using optimal CT protocol. ⋯ Single phase CT could be a potential protocol for abdominal trauma patients. Use of single phase CT could significantly decrease the incidence of radiation-associated cancer in the future.

Comparative Study Observational Study
Comparison of critically ill patients from three freestanding ED's compared to a tertiary care hospital based ED.
Freestanding emergency departments (FEDs) care for all patients, including critically ill, 24/7/365. We characterized patients from three FEDs transferred to intensive care units (ICU) at a tertiary care hospital, and compared hospital length of stay(LOS) between patients admitted to ICUs from FEDs versus a hospital-based ED (HBED). ⋯ Patients transferred from FEDs to an ICU were similar in age and gender, but more likely to be white with a higher Charlson Comorbidity Index score. FED patients experienced shorter hospital length of stay compared to patients admitted from a HBED.

Comparative Study Observational Study
Video screen viewing and first intubation attempt success with standard geometry video laryngoscope use.
Direct laryngoscopy (DL) is the traditional approach for emergency intubation but video laryngoscopy (VL) is gaining popularity. Some studies have demonstrated higher first-attempt success with VL, particularly in difficult airways. In real-world settings, physicians choose whether or not to view the video screen when utilizing VL devices for tracheal intubation. Therefore, we sought to determine whether screen viewing is associated with higher intubation first-attempt success in clinical practice. ⋯ In this study of orotracheal intubations performed by emergency physicians with Macintosh-style VL, the first-attempt success rate was high. The success rate was similar whether or not the intubating physician chose to view the video screen.

Well recognized guidelines are available for the use of cranial computed tomography (CCT) in traumatic patients, while no definitely accepted standards exists to for CCT in patients without history of head injury. The aim of this study is to propose an easy clinical score to stratify the need of CCT in emergency department (ED) patients with suspect non-traumatic intracranial pathology. ⋯ A score for risk stratification of patients with suspect of intra-cranial pathology could reduce CT request in ED, avoiding a significant number of CCT while minimizing the risk of missing positive results.

Case Reports
Anomalous left anterior descending artery diagnosed on pulmonary artery computed tomography.
Typically, the left anterior descending artery (LAD) and left circumflex artery (LCX) arise from the left main coronary artery. However, uncommon coronary anomalies may be found in clinical practice. This case presents with a rare finding where the LAD originates from the right coronary artery (RCA) separately from the LCX and takes an interarterial pathway to reach its perfusion territory. ⋯ However, it is important to realize the different pathways of coronary artery anomalies because those with the inter-arterial subtype, such as our patient, may result in sudden cardiac death. All cases of clinically suspected inter-arterial coronary artery anomalies are recommended to undergo imaging studies to help visualize anatomic features as a guide for further management. This case represents the first reported diagnosis of this type of anomalous coronary artery on CTPA.
