Application of delayed lung imaging following radioaerosol inhalation.

Lung scintigraphy following radioaerosol inhalation reveals evidence of airway disease and regions of decreased ventilation. In obstructive pulmonary diseases, aerosol deposition can be so excessive that lung parenchyma is not visualized immediately after radioaerosol administration. Most of the tracer which is deposited is cleared within hours, but the aerosol reaching the alveoli is retained with a half-life in excess of 2 weeks. If imaging is repeated 8-24 hours after inhalation, abnormal bronchi will usually be cleared of tracer, and regional ventilation defects can be visualized.

Radionuclidic lung-imaging procedures in the assessment of injury due to ammonia inhalation.

Clinical, physiologic, and bronchoscopic findings in a young man with acute injury of the respiratory tract due to inhalation of ammonia are described. Six months later, the patient's pulmonary function was reassessed by three radionuclidic lung-imaging procedures, which first revealed the sites and extent of the persisting obstructive disease processes. The diagnostic accuracy of the initial findings with radioactive xenon and aerosol were verified by the results of repeated bronchoscopic examination, bronchographic studies, standard pulmonary function tests, and lung-imaging procedures.

The need for leadership in hospital respiratory services.

The duration of a position as physician-director of respiratory services proved to be less than five years in 68 per cent of cases followed.Based on available information, in the 50 such cases, the act of separation was not elective in these instances, except as a final response to an otherwise intolerable situation. Further study revealed the prime cause to be ignorance of the basic essentials of management. Technical incompetence was never an issue in cases of separation. The general application of principles of management to the control of respiratory services is illustrated by a series of case reports and subsequent discussion. Presently, candidates aspiring to such positions appear to rely almost entirely on their elaborate technical skills. Choice of such a career option, however, should carry with it an obligation to "learn the rules of the game." Logically, graduate training programs should provide this training.
