Case ReportsElliptical cricoid cartilage: a unique type of congenital subglottic stenosis.
An elliptically shaped cricoid cartilage, a specific type of congenital subglottic stenosis, is described, and the laryngoscopic and radiographic findings in three cases are discussed. An "hourglass" deformity of the subglottic laryngeal airway on an anteroposterior airway radiograph is suggestive of this diagnosis.

Four distinct forms of pulmonary disease caused by talc have been defined. The first form, talcosilicosis, is caused by talc mined with high-silica-content mineral. Findings in this form are identical with those of silicosis. ⋯ Radiographic abnormalities associated with talc can be predicted when there is sufficient history of the nature of exposure, including the region of origin of the talc in cases of inhalation. Radiographic changes, such as diaphragmatic plaques, often attributed to both talc and asbestos have not been documented to be caused by talc alone. The author provides review of 18 well-documented cases.

The use of computed tomography (CT) has had a tremendous impact on the evaluation and management of blunt abdominal trauma. It is noninvasive, easy to perform, and has been shown to be highly sensitive (100%), specific (96.8%), and accurate (97.6%). ⋯ The use of other diagnostic tests such as radionuclide scans and angiography in blunt abdominal trauma has been virtually replaced by CT. Of the 41 peritoneal lavages performed in 1983, 39 were in patients who were in the operating room for treatment of other extraabdominal injuries (i.e., closed head injury, severe extremity trauma).
