A patient with a delayed aorto-right ventricular fistula and aortic valve injury after penetrating trauma is reported, and 17 similar additional cases from the literature reviewed. By examining the aortic root of adults with normal cardiac anatomy at autopsy, we defined the target area for these injuries as a 2 X 2 cm contact surface between the aorta above the right coronary cusp and the right ventricular outflow tract below the pulmonary valve. Five of the 18 patients required emergency exploration due to hemodynamic instability. ⋯ Patients with combination aortic valve and aortocardiac fistula injuries, more so than those with a single intracardiac lesion, fail with nonoperative management. Of the 18 patients, 17 underwent surgery. One of these died: the others did well during short-term followup (less than 1 year).

The high cost of health care has become a nationwide concern and there are several national initiatives under way to reduce the rate of increase of these costs. Among the most recent initiatives has been the introduction of Medicare reimbursement based upon Diagnostic Related Groups (DRGs). This paper presents a retrospective analysis of the costs of care of burned patients admitted to the University of Alabama at Birmingham Burn Center and a profile of the financial impact of DRGs. ⋯ In 1983, if the care for Medicare patients had been reimbursed on the bases of DRG rates, the payment would have been $409,629 less than costs and $634,583 less than charges. This very unfavorable reimbursement is because DRG reimbursement is essentially a flat rate and for long lengths of stay costs are much greater than reimbursements. Specific policies on methods to correct this discrepancy are suggested.

Most foreign bodies in the chest do their damage at the time of injury. While needle-like objects may migrate (6), delayed intrathoracic injury is rare. Delayed transthoracic penetration of the heart by a staple is reported, and is felt to be unique because acute hemopericardium resulted 30 days after the time of initial injury. The principles of recognition of pericardial tamponade, initial stabilization with periocardiocentesis, and immediate exploration are emphasized.

Complete dislocation of the tarsal cuboid is presented along with regional anatomic considerations. Thorough literature search revealed only three other reported cases of dislocation of the tarsal cuboid. ⋯ It should be emphasized that A-P, lateral, and oblique X-rays should be obtained for injuries of the mid and forefoot. The rarity of such a dislocation is attributed to the structural integrity of the supporting ligamentous elements.
