Furthermore, even if we employ only the FEVj as a reliable indication of airflow obstruction and bronchial reactivity, we still find that 30 of the total 153 (20 percent) AIDS patients treated at this institution had abnormal airway function. Recognition of abnormal airway function had clinical importance in our patients. The symptoms of cough and […]

Although a prevalence rate for bronchospastic disorder in AIDS has been reported in an earlier study, the prevalence cited in that report (3 percent) was considerably lower than that found here, and, in fact, was close to the rate of airway hyperreactivity found in the general population. This discrepancy is not attributable to physiologic criteria […]

Relation of Abnormal Airways Function to Clinical Events We examined the temporal relationship of PFT results to episodes of Pneumocystis carinii pneumonia (PCP) and the presence of systemic Kaposis sarcoma (KS) for possible clues to the pathogenesis of airway dysfunction. Among the 99 AIDS patients reported here, 54 percent had developed PCE while 29 percent […]

Prevalence of Abnormal Airway Function in AIDS From January 1983 to July 1986, 105 AIDS patients were referred for pulmonary physiologic assessment. Ninety-nine (94.3 percent) of these individuals were able to perform three FVC maneuvers acceptable for analysis. The 105 patients referred to the PFT lab represent 68.6 percent of those with AIDS who were […]

A standard approach was employed in the assessment of forced expiratory flow rates. Flow rates were considered to be abnormally low if either the ratio of forced expiratory volume in 1 s (FEVJ to the forced vital capacity (FVC) or the mean forced expiratory flow during the middle half of the FVC (FEF 25-75%) was […]

Individuals with the acquired immunodeficiency syndrome (AIDS) are subject to frequent often fatal pulmonary complications. Infections 4*4e to a myriad of opportunistic and common pathogens as well as noninfectious processes such as majignancy and lymphocytic interstitial pneumonitis have been identified in this setting. In addition, anatomic obstruction of upper and central airways may occur as […]

Tracheobronchial Tree Many methods have been used to evaluate airway obstruction. The most often used is conventional radiography. A recent study in pediatric patients demonstrated MR images in the sagittal and axial plane allowed clear demonstration of tracheal compression and narrowing secondary to a variety of etiologies. Correlation with endoscopy showed the appearance on MR […]

Pulmonary Vascularity Since the introduction of MR there has been some interest in the use of MR in the evaluation of the pulmonary arteries in order to allow detection of pulmonary embolism and/or thrombus. Studies have been performed both in the animal model and in humans presenting with pulmonary embolus and/or thrombus.’ The experiments in […]

When evaluating patients following radiation therapy it is important to recall the time course of radiation-induced changes within the lungs. In the early stages, seen 6 to 12 weeks after radiation, there is an acute reaction termed radiation pneumonitis. The late or chronic phase of radiation change is associated with replacement of normal lung parenchyma […]

Mediastinoscopy provided a sensitivity of 87.1 percent, specificity of 100 percent and an accuracy of 95.2 percent. Mediastinoscopy in this study exceeded all the other modalities as the most accurate staging method for detecting bronchogenic carcinoma. Another study evaluating primary lung carcinoma staging comparing MR and CT found no statistically significant differences between the two […]
