Detection of pooled secretions above endotracheal-tube cuffs: value of plain radiographs in sheep cadavers and patients.
Mechanical ventilation is thought to increase the risk of nosocomial pneumonia by permitting leakage of bacteria-laden gastro-oropharyngeal secretions into the upper airways. The goal of this study was (a) to validate radiographic signs of pooled secretions above endotracheal-tube cuffs (supracuff liquid) in an animal model and (b) to determine whether suctionable pooled supracuff liquid can be identified on bedside radiographs of intubated patients. ⋯ Radiography is a sensitive means of identifying small volumes of supracuff liquid above the inflated cuffs of endotracheal tubes. Potentially contaminating liquid pooled above the cuff of an endotracheal tube can be identified in about half of patients undergoing short-term mechanical ventilation. Our results suggest the suction of the supracuff space may be a reasonable prophylactic maneuver against nosocomial pneumonia. A much larger study is suggested to investigate the actual relation between pooled supracuff liquid and the development of nosocomial pneumonia.

Thoracostomy tubes after acute chest injury: relationship between location in a pleural fissure and function.
The purpose of this study was to determine how often chest tubes placed for acute trauma lie within a pleural fissure and to determine whether an intrapleural location influences outcome. ⋯ A large percentage of tubes placed for acute chest trauma lie within a pleural fissure. These tubes, however, appear to function as effectively as those located elsewhere in the pleural space.

Diffuse small-bowel ischemia in hypotensive adults after blunt trauma (shock bowel): CT findings and clinical significance.
The purpose of this study is to describe CT findings of shock bowel (diffuse abnormality of the small bowel observed in hypotensive or hypoperfused patients after blunt abdominal trauma) and to determine the clinical significance of CT-diagnosed shock bowel. ⋯ In trauma patients with hypotension, early abdominal CT may show diffuse abnormalities of the small bowel due to prolonged hypoperfusion--shock bowel--with a normal appearing colon. In this study, the CT findings of shock bowel were reversible and were not associated with clinical symptoms.

The job market for radiology residents and fellows graduating in 1994.
In response to anecdotal reports of grave deterioration in the job market for graduates of radiology training programs, the American College of Radiology undertook a systematic appraisal of this job market for 1994. ⋯ Although the overwhelming majority of 1994 graduates obtained jobs, and these overwhelmingly were jobs of interest, program directors reported that the job market was weakening. Given the changes in the socioeconomic environment--managed care, for example--and the changing job market, training programs should give more attention to the job market in planning for changes in size.
