Cervical spine injury: a clinical decision rule to identify high-risk patients for helical CT screening.
We aimed to validate the routine use of a clinical decision rule to direct diagnostic imaging of adult blunt trauma patients at high risk for cervical spine injury. ⋯ The clinical decision rule can distinguish patients at high and low risk of cervical spine injury, thus supporting its validity.

Our objective was to evaluate the CT appearance of talcosis associated with IV abuse of oral medications and to compare the findings of talcosis related to methylphenidate with those findings seen with other drugs. ⋯ The CT manifestations of talcosis consist of a fine micronodular pattern, ground-glass attenuation, and emphysema. A significantly increased prevalence of lower lobe panacinar emphysema is seen in IV drug addicts who abuse methylphenidate.
