Duodenal tuberculosis is a very rare disease and is usually associated with active pulmonary tuberculosis. These patients may present with symptoms and initial radiographic findings of pyloric canal obstruction. Hypotonic duodenography may reveal a submucosal mass with no other specific changes. The lesion is unpredictable. It may respond to medical therapy but it may also progress and require surgical intervention.
Segmental tuberculosis of the transverse colon is very rare and when present is usually associated with active pulmonary tuberculosis. These patients may have initial symptoms suggestive of neoplasm or of Crohn's disease. Radiographically the lesion manifests itself as a fairly long area of narrowing with nodular and ulcerated mucosa. Sinuses and fistulae may arise from the area of involvement. These changes are not specific for tuberculosis. The lesion is unpredictable. It may respond to medical therapy, but complications such as bleeding and sinus tract formation may require surgical intervention.
Claims analysis and efficacy study are two new methods of evaluating medical services. In Manitoba, with a 1974 population of 1,053,382, approximately 100,000 patient-physician interfaces resulted in 16,594 barium enema examinations; 1,000 significant abnormalities were discovered, and the referring physician was unusally perceptive in predicting the likelihood of these abnormalities. It is estimated that a 10% reduction in the use of barium enemas could be achieved by referring physicians with no deterioration in the care of patients.
Radiologic interpretation of malignant disease of the oral cavity, maxilla and mandible is often difficult. This is usually due to the fact that benign osseous diseases may mimic malignant lesions. This review attempts to provide a framework of interpretive criteria for establishing a radiologic diagnosis of malignancy.
