Tracheobronchial aspergillosis in a patient with AIDS treated with aerosolized amphotericin B combined with itraconazole.

The clinical features of a tracheobronchial infection due to Aspergillus flavus in an AIDS patient with a normal neutrophil count is described. Diagnosis was made by culture and microscopic examination of biopsies obtained from bronchial vegetations seen at bronchoscopy. Radiographic examination of the neck revealed the presence of large endoluminal fungal masses. Initially the patient was treated with a combination of itraconazole, flucytosine and aerosolized amphotericin B, then only with itraconazole plus aerosolized amphotericin B. A good therapeutic response was observed.

Pulmonary function in the patients submitted to lung exeresis.

The effects of lung surgery on respiratory function were investigated in 80 patients; 17 patients were submitted to left pneumonectomy (LPN); 11 patients were submitted to right pneumonectomy (RPN); 7 patients underwent a left upper lobectomy (LUL); 16 patients a left lower lobectomy (LLL); 17 patients were submitted to right upper lobectomy (RUL); 12 patients underwent right lower lobectomy (RLL). All patients were submitted to spirometry and arterial blood gas analysis. The effects of lung surgery on respiratory function depends upon the extent of the resected tissue.

Pulmonary function in patients with pleural effusion of varying magnitude and fibrothorax.

Pulmonary function was studied in sixty patients with pleural effusion and seventy patients with fibrothorax. The patients with pleural effusion were divided into three groups according to the extent of the effusion. The patients were submitted to spirometry and arterial blood gas analysis. The effects of pleural effusion on pulmonary function is evaluated with regards to the size of effusion. Small-size pleural effusion little affects arterial oxygen tension. Pleural effusion and fibrothorax have a similar pattern of pulmonary function.

Respiratory function during oxygen administration in chronic obstructive pulmonary disease.

Patient with severe chronic obstructive pulmonary disease (COPD) can develop respiratory muscle weakness and fatigue. Arterial hypoxemia can predispose to this condition. To assess whether O2 administration improved respiratory muscle function and respiratory pattern in COPD 11 patients with chronic hypoxemia were examined. Each patient was first submitted to respiratory function studies, including lung volumes, in normal and recumbent position, respiratory frequency, Ti/Te, Ti/Tot, maximal inspiratory and expiratory pressures (Pimax, Pemax) and arterial gas analysis breathing room air. All these tests were repeated during oxygen Administration through a nasal cannula. The arterial PO2 improved from 50 +/- 7 mmHg to 81 +/- 28 mmHg but the breathing pattern, Pimax and Pemax as well as lung volumes remained unchanged. It is concluded that oxygen, in short term administration, doesn't influence respiratory pattern and muscle function.
