Severe hemoptysis associated with pulmonary aspergilloma. Percutaneous intracavitary treatment.

Surgical therapy for massive hemoptysis associated with pulmonary aspergilloma carries a high morbidity and mortality in patients with limited pulmonary reserve. Bronchial artery embolization has proven ineffective in treating and in preventing recurrent episodes of hemoptysis in this group of patients. Over a four-and-one-half year period, we have successfully treated six episodes of acute hemoptysis in four patients using a percutaneously placed catheter and intracavitary instillation of amphotericin B, N-acetylcysteine, and aminocaproic acid.

Legionella pneumophila pericarditis proved by culture of pericardial fluid.

Serogroup 1 Legionella pneumophila was isolated from the pericardial fluid of a nonimmunosuppressed patient with pulmonary infiltrates, cardiac tamponade, and histologic evidence of pericarditis. This is the first reported case in which the association of L. pneumophila infection and pericarditis has been proved by growth of the organism from pericardial fluid.

Factors influencing theophylline serum protein binding.

We studied a number of influences on theophylline binding to serum proteins using equilibrium dialysis (37 degrees), a modified Krebs-Ringer bicarbonate buffer (pH 7.4), and 8-14C-theophylline with unlabeled theophylline (30 microgram/ml) added to sera from healthy subjects. Theophylline protein binding rose by 18.
