Ganciclovir-resistant, cytomegalic interstitial lung disease in a patient with systemic lupus erythematosus.

A patient with systemic lupus erythematosus developed interstitial lung disease initially felt to be a manifestation of the disease but that, on further workup, proved to be a manifestation of cytomegalic disease resistant to ganciclovir. Treatment with foscarnet was associated with prompt improvement.

Air pollution effects on myocardial infarction.

Objective: Myocardial infarction is an acute and severe cardiovascular disease that generally leads to patient admissions to intensive care units and few cases are initially admitted to infirmaries. The objective of the study was to assess whether estimates of air pollution effects on myocardial infarction morbidity are modified by the source of health information.

Methods: The study was carried out in hospitals of the Brazilian Health System in the city of São Paulo, Southern Brazil.

Metabolic and hemodynamic effects of saline infusion to maintain volemia on temporary abdominal aortic occlusion.

Objective: To analyze hemodynamic and metabolic effects of saline solution infusion in the maintenance of blood volume in ischemia-reperfusion syndrome during temporary abdominal aortic occlusion in dogs.

Methods: We studied 20 dogs divided into 2 groups: the ischemia-reperfusion group (IRG, n=10) and the ischemia-reperfusion group with saline solution infusion aiming at maintaining mean pulmonary arterial wedge pressure between 10 and 20 mmHg (IRG-SS, n=10). All animals were anesthetized with sodium thiopental and maintained on spontaneous ventilation.
