Does interleukin-2 sequester activated lymphocytes into lung lymph of sheep?
The lymphocyte populations decreased more than could be explained by the increase in lymph flow, demonstrating that lung lymphocytes were not reduced simply by dilution. These results imply that the pulmonary edema associated with IL-2 is not caused by activated lymphocytes.
Trauma influences the microbiology of pneumonia and it should be considered in the initial antibiotic regimen choice. Our data demonstrate that patients with trauma had a higher prevalence of MSSA, but the overall prevalence was sufficiently high to warrant S. aureus coverage for both groups. On the other hand, since no MRSA was isolated during the first 10 days of mechanical ventilation on trauma patients, MRSA coverage in these patients becomes necessary only 10 days after admission.
