Abdominal radiography is often requested; however, its results contribute to patient treatment in a small percentage of cases. With the exception of catheter placement, if a patient requires investigation beyond clinical history, physical examination, and lab results, the emergency physician should be encouraged to request more definitive imaging.

Laparoscopic repair should remain in the forefront for the management of paraesophageal hernias. However, there is considerable room for improvement in reducing the incidence of recurrence.

The rates of past psychiatric disorders among solvent-exposed subjects are similar to those among normal control subjects, but the prevalence of current DSM-IV axis I psychiatric disorders is significantly higher among exposed subjects than among control subjects.

The purpose of this study was to determine the movements of the patella in relation to the other bones of the knee joint during normal walking. This is the first study we know of that uses radiographs to show these movements.SUBJECTS AND METHODS. Eight healthy adult volunteers with no previous cornplaints referable to the knee walked on a slowly moving treadmill while their patellae were imaged fluoroscopically in the anteroposterior plane with a Toshiba C-arm. Images were retrieved, transferred to radiographic film, and randomized to prevent the observers from knowing the order of images. The position of the patella was measured and plotted in relation to fixed points of the knee. RESULTS. In each of the subjects at every gait cycle, the patella was observed to move vertically first, followed by a sudden shift to the medial side before returning to its original position. CONCLUSION.Contrary The management of painful and subluxated patellae must be reevaluated in light of this finding. AJR 1993;161 :617-620
