Pulmonary Disease From Nontuberculous Mycobacteria in Patients With Human Immunodeficiency Virus: Mycobacterium kansasii

Mycobacterium kansasii is antigenically and clinically more closely related to M tuberculosis than many of the other NTM species. Although this organism may be cultured from environmental water sources, it is less likely to be recovered from nonhuman sources and … Continue reading

Pulmonary Disease From Nontuberculous Mycobacteria in Patients With Human Immunodeficiency Virus: Literature Review

The literature on MAC and AIDS has emphasized the frequency and importance of disseminated disease, and reports of specific pulmonary manifestations have been few. Two autopsy series from the early years of the AIDS epidemic suggested that although MAC can … Continue reading

Pulmonary Disease From Nontuberculous Mycobacteria in Patients With Human Immunodeficiency Virus: Mycobacterium avium Complex

The patient is a 34-year-old man from Puerto Rico with AIDS, previously complicated by Pneumocystis pneumonia and cryp-tococcal meningitis. In December 1991, he was hospitalized with fever, weight loss, cough, and right upper lobe pulmonary infiltrate (Fig 3). Cultures were … Continue reading

Pulmonary Disease From Nontuberculous Mycobacteria in Patients With Human Immunodeficiency Virus: Results

Four cases of NTM pulmonary disease were identified: two with M avium, one with M kansasii, and one with M fortuitum and M xenopi. Fifty-three additional patients had at least one sputum culture positive for nontuberculosis mycobacteria without evidence of … Continue reading

Pulmonary Disease From Nontuberculous Mycobacteria in Patients With Human Immunodeficiency Virus: Methods

Nontuberculous mycobacterial species (NTM) are common environmental organisms and occasional colonizers of the human respiratory system. Timpe and Runyon and others in the 1950s established the potential pathogenicity of these organisms in human disease and created a widely used classification … Continue reading

Compression of the Left Main Bronchus Between a Descending Thoracic Aortic Aneurysm and an Enlarged Right Pulmonary Artery: Discussion

The lung beyond the compression was filled with fluid and bronchiectatic. Also noted were calcified pleural plaques and patchy right upper lobe pneumonia, which had not been apparent on the chest radiograph obtained on admission. A thoracic surgical opinion was … Continue reading

Compression of the Left Main Bronchus Between a Descending Thoracic Aortic Aneurysm and an Enlarged Right Pulmonary Artery: Case Report

Physical examination revealed a toxic, cachectic looking man in moderate respiratory distress. His blood pressure was 100/60 mm Hg, his pulse rate 100/min, and his respiratory rate 28/min. His temperature was 36.9°C. He was using his accessory muscles and had … Continue reading

Compression of the Left Main Bronchus Between a Descending Thoracic Aortic Aneurysm and an Enlarged Right Pulmonary Artery

Descending thoracic aortic aneurysms rarely cause tracheobronchial compression, unlike the aortic arch aneurysms in which this complication is well known. We review the case report of a patient with compression of the left-main bronchus between an enlarged right pulmonary artery … Continue reading

Identification of Low-Risk Hospitalized Patients With Pneumonia: Conclusion

Our study has several limitations. Because patients were enrolled in our study retrospectively, the observation that a patient did not suffer a complication while receiving parenteral antimicrobial therapy does not ensure that patient outcomes would not have been compromised had … Continue reading

Identification of Low-Risk Hospitalized Patients With Pneumonia: Discussion

During the first 3 days of hospitalization, an increasing amount of information becomes available to physicians including the pathogen causing the episode of pneumonia (in some cases) and the patient’s initial response to antimicrobial therapy. This information can be used … Continue reading
