Bacterial tracheitis after an upper viral respiratory infection is a well-recognized entity in the pediatric literature. Bacterial tracheitis has only recently been reported in adults, and it is a potentially life-threatening illness. We report a case of bacterial tracheitis in a patient with AIDS.
A large number and variety of organisms can infect the lungs of persons with AIDS. An abnormal chest X-ray associated with pulmonary symptoms should trigger a vigorous search for an infectious agent. In many cases, if the patient is ambulatory, the workup can proceed on an outpatient basis. Pneumocystis carinii pneumonia is the most common infection and also one of the most readily treatable illnesses that these patients encounter. A careful and considered diagnostic approach is necessary to conserve the time and resources of both patients and healthcare providers.

Prehospital coronary care is becoming a common feature of community emergency medical systems. To date, results have been reported in a variety of formats, making meaningful comparison and aggregate analysis impossible. A flexible patient encounter form and data analysis scheme are proposed for universal adoption in future published accounts.
Biopsy specimens of the myocardium for electron microscopical study were taken from patients who were having surgical operations for correction of aortic and mitral valve lesions. Ultranstructural changes characteristic of hypertrophy and ischemia were found in the left ventricles of groups with aortic and mitral lesions. The severity of the cardiomyopathy was greater in hearts that had aortic lesions than in those that had mitral lesions. Both groups, however, displayed degenerative changes to an extent not readily appreciated or expected when their clinical histories and catheterization data were obtained.
