To quantify white matter (WM) and gray matter (GM) damage in patients who presented with clinically isolated syndrome (CIS), which is suggestive of multiple sclerosis (MS), by combining volume-based morphometry (VBM) and tract-based spatial statistics (TBSS). ⋯ Diffuse WM damage not accompanied by any change in GM or WM volume is observed in patients with CIS. This suggests that WM involvement plays a relevant role in the early phases of MS. Subsequently detected GM damage may be secondary to WM alterations.

To prospectively evaluate the use and optimal timing of ultrasonographic (US) screening for posterior shoulder subluxation in infantswith brachial plexus birth injury (BPBI). ⋯ US is a fast and useful tool for diagnosis of posterior subluxation of the humeral head, and examination of the glenohumeral joint should be performed at 3 and 6 months of age in infants with BPBI if symptoms persist.

To determine the diagnostic yield of multidetector computed tomographic (CT) angiography in the evaluation of patients presenting to the emergency department with acute blunt head and neck trauma to assess for arterial injury and to propose a practical scoring system for the identification of patients at highest risk of arterial injury. ⋯ The proposed acute craniocervical trauma scoring system could be used as a guide to select blunt trauma patients for multidetector CT angiographic evaluation. Future validation of this scoring system is necessary.

To determine the multidetector computed tomographic (CT) features of crush thoracic traumas resulting from the massive Sichuan earthquake. ⋯ Crush thoracic trauma resulting from the massive Sichuan earthquake was a life-threatening injury; this type of injury has the potential for multiple fractures and pulmonary parenchymal injuries.
