Comparative Study
Value of computed tomography of the lung in the management of primary spontaneous pneumothorax.
The treatment of patients with primary spontaneous pneumothorax remains controversial, since recurrence and the ultimate need for thoracotomy [corrected] cannot be predicted. In the current study, computed tomography (CT) of the lung was performed prospectively on 26 consecutive patients with primary spontaneous pneumothorax to determine whether the size and/or the number of apical blebs would correlate with recurrence and/or need for thoracotomy [corrected]. Both the number of blebs and the bleb score (calculated by the number of blebs multiplied by a numeric value assigned a range of bleb sizes) of the affected lung was significantly greater in patients with a history of recurrent pneumothorax and/or ultimate need for thoracotomy [corrected] as treatment. CT of the lung may be useful in predicting the natural history of pneumothorax.

Management of compound fractures remains a challenge to the surgeon. Methods to decrease patient morbidity include early fracture stabilization and sequential débridement. ⋯ The use of prophylactic parenteral antibiotics has decreased the incidence of acute infection and chronic osteomyelitis. Supplemental use of local antibiotic polymethyl methacrylate (PMMA) beads appears to further diminish the morbidity in high-grade open fractures.

Nosocomial pneumonia is frequent and is associated with high mortality in intubated mechanically ventilated patients. To determine whether there is a significant relationship between subclinical aspiration from nasogastric feeding and development of nosocomial pneumonia, we studied 24 ventilated patients who received nasogastric feeding. Endotracheal aspirates were tested twice daily for the presence of glucose using a glucose oxidase reagent strip. ⋯ The remaining five patients had nonbloody glucose-positive endotracheal aspirates and all developed nosocomial pneumonia. There was a significantly greater incidence of pneumonia among patients who had nonbloody glucose-positive aspirates than among patients without glucose-positive aspirates (p less than 0.001, Fisher's exact test). We conclude that subclinical aspiration of nasogastric feeding, as detected by nonbloody glucose-positive endotracheal aspiration, is associated with the development of nosocomial pneumonia.
