An experimental model of hypersensitivity pneumonitis is presented. New Zealand white rabbits, previously immunized against yeast-derived zymosan, reacted to intratracheal challenge developing extensive pneumonitis. The lesions healed in a few weeks. Control animals challenged with inert particulate material (latex beads) or suspending fluid (PBS-Mg++) did(More)

OBJECTIVE This study evaluated the presence of symptoms of depression and the quality of life of liver transplant candidates. METHODS One hundred liver transplant candidates underwent a(More)
Nonmyxomatous primary cardiac tumors are rare. Primary neurogenic tumors of the heart originating in the nerve sheath are extremely uncommon, and to date, 10 cases of neurilemomas, or schwannomas, have been reported. We report the case of a patient with a right atrial tumor who underwent a successful resection; histological examination revealed a benign(More)
Aortic arch aneurysm associated with an acute aortopulmonary fistula is rare and usually diagnosis is made during the postmortem. Few reports of successful surgical management have been reported and a high mortality rate remains. The authors report on a 78-year-old male patient with an acute aortic arch aneurysm communicating with the main pulmonary artery(More)
At the beginning of the twentieth century, Carrell and Guthrie were the first to use homografts to reconstruct dilated vessels, starting a new era in aorta surgery. In 1952, Cooley and DeBakey conducted the first successful ascending aorta intervention without cardiopulmonary bypass in the resection of a sacciform aneurysm by aortorrhaphy. In 1956, the same(More)

There are described 3 cases of patients with LED in which the obtained results of AAN's research, by means of IFI, were negative in a transitory or a permanent way. This situation can motive the doubt at the diagnostic, even though it exists in a little patients' group. In this work there are revised its causes and mechanisms.
