2973. Amiodarone pneumonitis. Bronchoalveolar lavage findings in 15 patients and review of the literature.
Amiodarone (Am) pneumonitis is currently a common and potentially severe adverse reaction, the accurate diagnosis of which remains difficult to establish.

Pulmonary venous infarction, although rare, can develop in patients with the various pathologic conditions outlined. The triad of cough, dyspnea, and hemoptysis should raise clinical suspicion. The venous phase of pulmonary arteriography is the best way to document pulmonary venous obstruction, although MR imaging may also prove useful in the future. Treatment of patients with pulmonary venous infarction should be determined on the basis of the obstructing pathologic findings. Antibiotic therapy is important, as evidenced by the early experimental experience with this condition. It may be the only treatment available to patients with idiopathic fibrosing mediastinitis. Pulmonary resection, however, can be accomplished when a localized obstructing lesion is identified.
2977. HIV-associated pericardial effusions.
Following a case of cardiac tamponade in a patient with the acquired immunodeficiency syndrome (AIDS), we examined the frequency and clinical spectrum of pericardial effusions associated with human immunodeficiency virus infection (HIV) at our institution. Of 187 hospitalized patients documented to have pericardial effusions over a one-year period, 14 (7 percent) were known to be HIV-positive at the time of their echocardiograms. One patient presented with a large effusion and cardiac tamponade, three had moderate effusions, and ten had small effusions. The probable effusion etiology was established in four cases and included endocarditis (2), lymphoma (1), and myocardial infarction (1). In hospital mortality was 29 percent (4 of 14). From our study, as well as a growing number of reports in the literature, we conclude that HIV-associated pericardial effusions are frequently seen and that their clinical spectrum is broad.
2978. Predisposition to and late onset of upper airway obstruction following angiotensin-converting enzyme inhibitor therapy.
Angioedema of the face and neck is a rare but potentially fatal complication of angiotensin-converting enzyme inhibitor (ACEI) use. We retrospectively reviewed five cases of ACEI angioedema seen at our institution over the past 2 1/2 years. Four of the cases occurred with enalapril and one with lisinopril. Onset of symptoms varied from two days to ten months. Importantly, three of the five patients had been receiving medication three months or longer, suggesting clinicians must consider this complication during long-term administration of these agents. Three of the five patients were markedly obese, had a history of previous face and neck surgery, or had been intubated in the past. Thus, we propose that previous manipulation or trauma of the upper airway, perhaps resulting in airway narrowing, may represent a risk factor for upper airway obstruction secondary to ACEI-induced angioedema.
2979. Relapsing fever associated with ARDS in a parturient woman. A case report and review of the literature.
We report a patient who survived acute respiratory failure associated with tick-borne relapsing fever in the third trimester of pregnancy. The fetus was delivered by cesarian section and did not have spirochetemia. The severity of the patient's illness may be related to the immunosuppressive effects of pregnancy.
