Current approaches to monitoring in severe traumatic brain injury (TBI) include a wide array of modalities, providing insight into pressure parameters, oxygenation, perfusion, electrophysiology and metabolism of the brain. The intent of "multimodality monitoring" is to obtain a better understanding of what is going on within the brain of an individual patient in order to target treatment more appropriately. In this review we highlight the current status of neuromonitoring for TBI with a specific focus on how advanced analysis and integration of these parameters may be used to implement more personalized treatment approaches. ⋯ Rather than persisting in a standardized "one size fits all" approach to therapy or continuing down the separate tracts of goal directed therapy, we suggest to think more in terms of "individualized therapeutic strategies" more focused on the specific requirements of each patient. Given the considerable data overload in multimodality monitoring and the complexity in interpretation of signals from multiple sources, specific attention needs to be directed to data processing and user-friendly displays. Intense collaboration and interaction between clinicians, basic researchers, IT-experts, nurses and industry will be required to further advance the fields towards more personalized approaches.

ReviewRight ventricular failure in acute lung injury and acute respiratory distress syndrome.
Acute respiratory distress syndrome (ARDS) is a clinical entity involving not only alveolar lesions but also capillary lesions, both of which have deleterious effects on the pulmonary circulation, leading to constant pulmonary hypertension and to acute cor pulmonale (ACP) in 20-25% of patients ventilated with a limited plateau pressure (Pplat). Considering the poor prognosis of patients suffering from such acute right ventricular (RV) dysfunction, RV protection by appropriate ventilatory settings has become a crucial issue in ARDS management. The goal of this review is to emphasize the importance of analyzing RV function in ARDS, using echocardiography, in order to limit RV afterload. Any observed acute RV dysfunction should lead physicians to consider a strategy for RV protection, including strict limitation of Pplat, diminution of positive end-expiratory pressure (PEEP) and control of hypercapnia, all goals achieved by prone positioning.

ReviewCommunity acquired methicillin resistant Staphylococcus aureus pneumonia: an update for the emergency and intensive care physician.
Pneumonia caused by community-acquired (CA) methicillin-resistant Staphylococcus aureus (MRSA) among individuals without healthcare-associated (HA) risk factors was first recognized a decade ago. CA-MRSA has now been established as a pathogen responsible for rapidly progressive, frequently fatal disease manifesting as necrotizing pneumonia, severe sepsis and necrotizing fasciitis. The frequency of occurrence, risk factors, and optimal treatment of CA-MRSA pneumonia remain unclear and vary significantly across countries. ⋯ Prompt hospitalization and aggressive treatment with intravenous antibiotics is warranted to improve outcomes. Therapeutic approach for severe CA-MRSA infections and particularly pneumonia is generally the same as that for invasive HA-MRSA infections. New anti-MRSA agents and possible combinations are of great importance to be evaluated in the future.
