The emerging problem of antibiotic resistance, especially among Gram-negative bacteria (GNB), has become a serious threat to global public health. Very few new antibacterial classes with activity against antibiotic-resistant GNB have been brought to market. ⋯ After an in-depth analysis, the Summit investigators were surveyed with regard to 4 clinical practice statements. The results then were compared with the same survey completed by 138 infectious disease and critical care physicians and are the basis of this article.

Exposure network analysis and molecular epidemiologic methods were used to analyze the emergence and regional spread of Klebsiella pneumoniae carbapenemase-producing Enterobacteriaceae over a 1-year period. Although 40 patients and 26 health care facilities were affected, 1 long-term acute care hospital played a critical role in the convergence of patients at high risk, amplification by cross-infection, and dissemination of these multidrug-resistant bacteria. ⋯ We observed extensive transfer of KPC-positive patients throughout the exposure network of 14 acute care hospitals, 2 LTACHs, and 10 nursing homes. Although few cases were identified at most institutions, many facilities were affected. Successful control of KPC-producing Enterobacteriaceae will require a coordinated, regional effort among acute and long-term health care facilities and public health departments.

Glucocorticoids increase the risk of developing critical disease from viral infections. However, primary care practitioners in China use them as antipyretics, potentially exposing hundreds of millions to this risk. ⋯ Early use of parenteral glucocorticoids therapy for fever reduction and pneumonia prevention increases the risk for critical disease or death from pH1N1 infection. We recommend that guidelines on glucocorticoid use be established and enforced.

Increased rates of empyema have been reported in children after the introduction of the pneumococcal conjugate vaccine (PCV7). Our objective was to describe the risk factors for pneumococcal empyema in adults and to analyze the differences in the incidence, disease characteristics, and serotype distribution between the pre- and post-PCV7 eras. ⋯ The incidence of pneumococcal empyema in young adults has increased during the postvaccine period, mainly as a result of the emergence of serotype 1. Serotypes 1 and 3 are the main determinants of development of this suppurative complication.

Randomized Controlled Trial Clinical Trial
Brain swelling and mannitol therapy in adult cerebral malaria: a randomized trial.
Coma is a frequent presentation of severe malaria in adults and an important cause of death. The role of cerebral swelling in its pathogenesis, and the possible benefit of intravenous mannitol therapy to treat this, is uncertain. ⋯ Brain swelling on CT scan is a common finding in adult patients with cerebral malaria but is not related to coma depth or survival. Mannitol therapy as adjunctive treatment for brain swelling in adult cerebral malaria prolongs coma duration and may be harmful.
