Five cases of infection due to colistin-resistant, Klebsiella pneumoniae carbapenemase-producing K. pneumoniae belonging to the international epidemic clone ST258 occurred over a 4-month period. These cases likely represented both emergence of resistance and transmission of resistant organism. The colistin-resistant isolates were able to persist in the absence of selective pressure in vitro.

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.

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.

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.
