An index to predict outcome in adult respiratory distress syndrome.
Thirty patients with adult respiratory distress syndrome required intermittent positive pressure ventilation; 15 survived. In 25 the syndrome followed bacterial infection or multiple injuries. From the peak upper airway pressure, the oxygen gradient and the age of the patient, an index was obtained which discriminated between the survivors and those who died from the pulmonary lesion of the syndrome.
Circumflex retroesophageal right aortic arch simulating mediastinal tumor or dissecting aneurysm.
The authors present three cases of circumflex right aortic arch, a retroesophageal arch in which the aorta crosses from right to left behind the esophagus to descend on the left side. The findings on the frontal chest films resembled those of a left arch with mediastinal widening, simulating a mass. Aortography revealed four-vessel branching of the arch vessels, typical of right aortic arch with aberrant left subclavian artery. Computed tomography and barium studies of the esophagus demonstrated the retroesophageal course of the aorta. In two patients, obstruction of the thoracic portion of the left subclavian artery resulted in differences in blood pressure and pulse between the arms, supporting the clinical impression of dissecting aortic aneurysm.

The transjugular technique of hepatic venography and biopsy, cholangiography, and obliteration of esophageal varices.
The transjugular technique facilitates various diagnostic and therapeutic procedures in the liver. Even in patients with defective hemostasis, severe ascites, or marked obesity, liver biopsy or cholangiography can be performed with relative safety. It also provides an alternative route for entry into the portal system.
Transcatheter vascular occlusion therapy with isobutyl 2-cyanoacrylate (bucrylate) for control of massive upper-gastrointestinal bleeding.
Transcatheter embolization with bucrylate, a tissue adhesive, was performed in 16 patients with massive upper-gastrointestinal bleeding. Control of arterial bleeding from the stomach was achieved in 6 of 8 patients, and from the duodenum in 3 of 4. Embolization of gastric veins resulted in temporary control of esophageal variceal bleeding in 3 of 4 patients. Histological study showed no evidence of bucrylate causing histotoxicity in 2 patients. Because bucrylate polymerizes rapidly, a localized vascular occlusion mimicking a surgical ligation is produced. Because collateral vessels are not occluded. localized tissue ischemia is unlikely. Tissue adhesives are, however, difficult to use.

The traumatic pneumomyelogram. A previously undescribed entity.
Air within the cervical subarachnoid space secondary to skull trauma (traumatic air myelogram or pneumomyelogram) has not been reported previously. Such a case is presented and the findings are reviewed in the light of existing literature.
Intra-arterial lidocaine: an effective analgesic for peripheral angiography.
Intra-arterial lidocaine was found to be an effective and safe method for reducing pain associated with peripheral angiography. A convenient method for delivery is to directly mix 2% lidocaine and contrast material in a ratio of 1:10 by volume. In a comparative evaluation, 25 of 29 patients experienced significantly less discomfort when the lidocaine-contrast mixture was used as compared to contrast material alone. There were no apparent complications from the use of intra-arterial lidocaine.
