RESUMO
During a 5-year period from 1983 to 1987, a total of 226 thoracotomies were performed at David Grant USAF Medical Center. Within this group, 62 patients (27%) had resection of a solitary pulmonary nodule. Fifty percent of the resected nodules were subsequently proven malignant, with 27 of 62 (43%) having a primary lung carcinoma. From 1958 to 1963, the Veterans Administration Armed Forces Cooperative Study evaluated a total of 1,134 patients with asymptomatic solitary pulmonary nodules. The data generated from that report has become the standard within the literature. We compared our recent 5-year experience to that data. The primary difference found in our series was an increase in solitary pulmonary nodules in our female population.

Carcinoid tumors comprise 1% to 2% of all tumors of the lung. Although carcinoid tumors are generally felt to be of low grade malignancy, an atypical variant exists that exhibits more virulent behavior and a less favorable prognosis. The treatment of carcinoid tumors is complete surgical removal and a more aggressive approach is required in the treatment of atypical carcinoids. A case is presented with a review of the literature.

An infectious, cytopathic paramyxovirus was rescued from the peripheral blood leukocytes of a patient with subacute sclerosing panencephalitis (SSPE) by cocultivation procedures. Cells infected with the virus (1) demonstrated polykaryocytosis, (2) contained cytoplasmic inclusion bodies of paramyxoviral nucleocapsids, (3) hemadsorbed monkey erythrocytes, and (4) reacted with fluorescein-conjugated antisera to measles virus. On the basis of these observations, the virus was initially believed to be measles-like virus similar to those that have been rescued from other patients with SSPE. However, subsequent immunologic and molecular studies showed that the virus was distinct from measles virus and was more closely related to simian virus 5. These findings suggest that paramyxoviruses other than measles virus can be nonproductively carried by patients with SSPE and should not be designated as "measles like" or "measles related" solely on the basis of their biologic characteristics.
