Case ReportsRadial head-capitellum view in elbow trauma: clinical application and radiographic-anatomic correlation.
The radial head-capitellum view, first reported 2 years ago, has proved useful in the evaluation of elbow trauma. Minimally displaced or nondisplaced fractures of the radial head, capitellum, and coronoid process are better demonstrated on this special projection than on traditional radiographs of the elbow. To test the accuracy of this view, 50 patients with trauma to the elbow were examined and routine anteroposterior, lateral, and external oblique radiographs were compared with this special angled projection. ⋯ It revealed that fractures of the posterior half of the radial head were particularly difficult to diagnose on the traditional lateral view. The radial head-capitellum view not only distinctly delineated these fractures, it showed the full extent of their articular displacement. The authors recommend the use of this technique in all cases of chronic and acute trauma to the elbow joint.

One hundred consecutive children with serious blunt upper-abdominal injury were evaluated prospectively to assess the accuracy and usefulness of emergency computed tomography (CT) compared with liver-spleen scintigraphy and sonography. Ninety-five hemodynamically stable patients were imaged. The results of this 20-month study indicate that CT has fewer false negatives and false positives than scintigraphy or sonography, that CT is useful in abdominal trauma, and that CT provides the most information of any single diagnostic imaging test commonly available.

Mediastinal-width/chest-width ratio in blunt chest trauma: a reappraisal.
The chest radiographs of 54 patients with blunt chest trauma and suspected aortic rupture were reviewed retrospectively. A mediastinal-width/chest-width ratio was calculated at the level of the aortic arch. ⋯ There was no identifiable ratio of significance in distinguishing those with aortic rupture and those without rupture. The mediastinal-width/chest-width ratio is of insufficient sensitivity and specificity in confirming or excluding aortic rupture to be clinically useful.

Case ReportsCT of bilateral adrenal hemorrhage with acute adrenal insufficiency in the adult.
Bilateral adrenal hemorrhage and acute adrenal insufficiency in three acutely ill patients occurred as a complication of pneumonia in two and recent abdominal surgery in the third. The diagnosis was unsuspected in each case before abdominal computed tomography (CT), which showed bilateral adrenal masses. ⋯ Adrenal insufficiency was confirmed by endocrine studies, and each patient promptly recovered with steroid replacement therapy. Follow-up CT showed diminution or disappearance of the masses and density changes consistent with resolving hematomas.
