Recent ventilator-associated pneumonia (VAP) guidelines recommend considering abbreviated therapy in patients with non-Pseudomonas aeruginosa VAP if clinical signs resolve. However, using an arbitrary day cutoff or clinical signs can be suboptimal for some, especially multiply injured patients, resulting in relapse and/or antibiotic resistance. Previously, we showed that repeat bronchoalveolar lavage (BAL) could guide antimicrobial duration for community-acquired VAP in trauma patients. The purpose of this study was to determine the appropriate duration of antimicrobial therapy for VAP in trauma patients secondary to hospital-acquired pathogens. ⋯ Repeat BAL provides objective evidence for VAP resolution in the face of potentially confounding clinical factors. Hospital-acquired VAP can be managed effectively by a defined course of therapy with a low recurrence. Duration of antimicrobial therapy for VAP in trauma patients should be dictated by the causative pathogen.

Several thousand snakebites occur annually in the US, but fewer than 10 deaths occur. Most deaths are from envenomations by rattlesnakes (Crotalus species), but deaths from copperhead and water moccasin (Agkistrodon species) are rare. ⋯ Accurate identification of the pit viper species involved in snakebites is essential. Although envenomation by a rattlesnake (Crotalus species) may require antivenom and uncommonly surgery, a bite by a copperhead (Agkistrodon contortrix) rarely requires any intervention other than observation. The unnecessary use of antivenom should be discouraged.

We have previously demonstrated that elevated serum estradiol (E(2)) at intensive care unit (ICU) admission is associated with death in the critically ill, regardless of sex. However, little is known about how changes in initial E(2) during the course of care might signal increasing patient acuity or risk of death. We hypothesized that changes from baseline serum E(2) during the course of critical illness are more strongly associated with mortality than a single E(2) level at admission. ⋯ Although high admission levels of E(2) are associated with mortality, changes from baseline E(2) in critically ill or injured adults are independently associated with mortality. Future studies of E(2) dynamics may yield new indicators of patient acuity and illuminate underlying mechanisms for targeted therapy.

Cystic lesions of the pancreas are being identified more frequently, and a selective approach to resection is now recommended. The aim of this study was to assess the change in presentation and management of pancreatic cystic lesions evaluated at a single institution over 15 years. ⋯ Cystic lesions of the pancreas are being identified more frequently, yet are less likely to present with concerning features of malignancy. Carefully selected patients managed nonoperatively had a risk of malignancy that was equivalent to the risk of operative mortality in those patients who initially underwent resection.

Rising medical malpractice premiums have reached a crisis point in many areas of the United States. In 2003 the Texas legislature passed a comprehensive package of tort reform laws that included a cap at $250,000 on noneconomic damages in most medical malpractice cases. We hypothesized that tort reform laws significantly reduce the risk of malpractice lawsuit in an academic medical center. We compared malpractice prevalence, incidence, and liability costs before and after comprehensive state tort reform measures were implemented. ⋯ Implementation of comprehensive tort reform in Texas was associated with a significant decrease in the prevalence and cost of surgical malpractice lawsuits at one academic medical center.
