Allergic bronchopulmonary aspergillosis.

Since 1968 the number of reported cases of allergic bronchopulmonary aspergillosis in the United States has risen secondary to increased awareness by physicians and to improved diagnostic criteria for identifying the disease. The eight diagnostic criteria, the five clinical stages of the disease, the common radiographic changes, the pathologic findings, the common laboratory findings, the possible pathogenetic mechanisms involved, the differential diagnosis, the acute and chronic pulmonary function changes, and the importance of corticosteroid therapy in treatment of exacerbations and prevention of further lung damage are reviewed.

Radiographic findings of infectious proctitis in homosexual men.

Homosexual men are known to have an increased incidence of sexually transmitted proctitis. A knowledge of the pathogenesis and the radiographic appearance of these processes has resulted in earlier diagnosis and more rapid institution of appropriate therapy. While gonococcus (Neisseria gonorrhoeae) and lymphogranuloma venereum (usually Chlamydia) have long been considered the common etiologies of proctitis in this population, other organisms, such as herpes, Mycoplasma, and Entamoeba have been implicated and could give an identical radiographic and clinical pattern. Diffuse narrowing and ulceration limited to the rectum was seen in five affected homosexual men recently studied at Northwestern Memorial Hospital, Chicago.

Evaluation of a new mobile automatic exposure control device.

Mobile chest radiographs obtained with manual technique and with an automatic exposure control device were compared in 50 patients requiring three radiographs within a 48 hr period. Parameters evaluated were overall quality, internal consistency, film latitude, lung field (consistency and quality), cardiac contour, hilar anatomy, pulmonary vascularity, mediastinum, tracheobronchial tree, and tubes and appliances. Radiographs obtained with the automatic exposure control system demonstrated better overall quality, consistency, film latitude, and lung field consistency and quality than manual technique. There was no definite advantage of the automatic exposure control device in the visualization of the hila, pulmonary vascularity, heart, or mediastinum. Tubes and appliances were seen equally well with both techniques. The automatic exposure control device has the potential to increase the quality and consistency of mobile radiographs, particularly in those critically ill patients who are radiographed at least on a daily basis.

Rounded atelectasis and its association with asbestos-induced pleural disease.

Rounded atelectasis (RA) is an unusual form of peripheral lobar collapse which may present as a juxtapleural mass simulating a pulmonary neoplasm. Seven cases of RA were recently encountered in patients with asbestos-induced pleural disease. Since asbestos exposure is associated with mesothelioma, bronchogenic carcinoma, and other tumors, differentiation of RA from these neoplasms is essential in avoiding unnecessary thoracotomy. The radiographic features of RA are sufficiently characteristic, so that in the presence of chronic pleural thickening due to asbestos exposure, the diagnosis can be made with assurance and further work-up avoided.

Computed vs. conventional tomography in evaluation of primary and secondary pulmonary neoplasms.

One hundred patients, ultimately proved to have chest malignancies, were evaluated prospectively with conventional chest tomography and computed tomography. In 58 patients with primary malignancies, conventional tomograms were more useful in evaluation of the hilus than CT scans. The mediastinum was better assessed by CT. Thus, evaluation of the presence of neoplasia is better accomplished by conventional examination, while extent of disease is best assessed by CT. Thoracotomy for curative resection was not attempted (in the latter cases of this series) based on CT findings of mediastinal involvement. In 42 patients with metastases to the chest, CT scans of the lung parenchyma were more sensitive than whole lung tomography but had little additional impact on patient treatment. Nevertheless, in 18 patients the results of CT or whole lung tomography directly affected patient therapy.
