Comparative StudyMonotherapy versus multi-drug therapy for the treatment of perforated appendicitis in children.
Children with perforated appendicitis often have a prolonged hospital course complicated by surgical site or intra-abdominal infections. Treatment with multiple intravenous (IV) antibiotics after appendectomy has been the standard of care for these patients. We have recently adopted a protocol using piperacillin-tazobactam (PT) as a single agent in lieu of the standard multi-drug regimen (MD). We hypothesized that PT would be as effective as MD in reducing postoperative complications and would result in decreased resource utilization. ⋯ Children with perforated appendicitis can be managed effectively with a single broad-spectrum antibiotic after appendectomy. Monotherapy is not only more efficacious than multi-drug therapy, but may be more cost effective. The use of monotherapy for children with perforated appendicitis after adequate source control should be considered the treatment of choice.

Randomized Controlled Trial Clinical TrialEffect of linezolid versus vancomycin on length of hospital stay in patients with complicated skin and soft tissue infections caused by known or suspected methicillin-resistant staphylococci: results from a randomized clinical trial.
Complicated skin and soft tissue infections are common surgical indications usually requiring patients to be hospitalized, and are often caused by gram-positive bacteria, including methicillin-resistant staphylococci such as MRSA. Vancomycin has been the standard treatment for methicillin-resistant staphylococcal infections in many countries, but its intravenous-only formulation for systemic infections often confines patients to the hospital for the treatment. Linezolid, a novel oxazolidinone antibiotic available in intravenous and 100% bioavailable oral forms, was shown in a randomized trial to be as efficacious as vancomycin for suspected or proven methicillin-resistant staphylococcal infections. To determine if oral linezolid can reduce length of hospital stay (LOS) when compared to vancomycin, we compared the LOS for the 230 complicated skin and soft tissue infection patients enrolled in this trial. ⋯ Results from this randomized trial show that linezolid can significantly reduce LOS for patients with complicated skin and soft tissue infections from suspected or confirmed methicillin-resistant staphylococci.

Comparative StudyInfections in 346 consecutive video-assisted thoracoscopic procedures.
Postoperative infections, as related to risk factors, in patients undergoing video-assisted thoracoscopic surgery (VATS) procedures have been studied infrequently. ⋯ This prospective study confirms that the wound infection rate is low (1.7%) after minimally invasive VATS procedures. The cumulative incidence of postoperative infections (including wound infection, pneumonia, empyema) was similar after lung wedge resection and after pleural or mediastinal mass biopsy procedures. Among the infection risk parameters, COPD was the only parameter associated with a significantly increased incidence of postoperative infection. Our results suggest that patients with COPD who undergo VATS for lung wedge resections and for pleural/mediastinal biopsy should receive antibiotic prophylaxis to prevent surgical site infection.

Does prior transfusion worsen outcomes from infection in surgical patients?
Controversy continues to exist regarding the immunomodulatory effects of cellular blood transfusions in the fields of oncology, transplantation, and infectious diseases. Numerous studies have correlated transfusion with hospital-acquired infection, but the impact of transfusion on infection-related mortality has not been addressed. The objective of this study was to determine the effect of transfusion on outcomes among infected surgical patients. ⋯ The transfusion of packed red blood cells or platelets prior to infection is associated with more severe disease among surgical patients, but once corrected for treatment selection bias does not appear to worsen outcomes from infection.

Pathogenesis of posttraumatic empyema: the impact of pneumonia on pleural space infections.
Thoracic empyema may result either from primary pneumonic sources or intraabdominal sources of infection that seed the pleural space secondarily. In patients with thoracostomy tubes, empyema may result when blood in the pleural space becomes contaminated during tube insertion. To elucidate the cause of posttraumatic empyema, preoperative bronchoalveolar lavage (BAL)/sputum cultures obtained from patients with posttraumatic empyema were compared with cultures obtained at the time of decortication. ⋯ Little correlation existed between preoperative BAL/sputum cultures and intraoperative cultures in this series of patients with posttraumatic empyema. This suggests that the causation is most often not a parapneumonic process. Furthermore, since S. aureus was the most common organism recovered from empyema, the source was more likely from inoculation of the pleural space by the injury itself or by tube thoracostomy.
