To develop a new classification of acute pancreatitis severity on the basis of a sound conceptual framework, comprehensive review of the published evidence, and worldwide consultation. ⋯ This classification is the result of a consultative process among specialists in pancreatic diseases from 49 countries spanning North America, South America, Europe, Asia, Oceania and Africa. It provides a set of concise up to date definitions of all the main entities pertinent to classifying the severity of acute pancreatitis in clinical practice and research. This ensures that the determinant-based classification can be used in a uniform manner throughout the world.

The present study outlines a series of questions and reflections upon the recent publication of Chesnut et al., who compared 2 approaches to the treatment of intracranial hypertension (ICH) in severe head injuries: one with and the other without intracranial pressure monitoring (ICP). The authors concluded that no improved outcome was observed in the treatment group guided by ICP monitoring. The main concerns relate to the degree of training of the physicians involved in the monitoring and management of ICH in the ICP group, as well as to the possible inter-observer variability in interpreting the CT scans, the capacity of clinical signs to guide the treatment of ICH, and the suitability of randomization. The analysis of this trial should not be taken to suggest the futility of ICP monitoring but rather the need to correctly use the information afforded by ICP monitoring, with emphasis on the importance of the definition of alternative methods for non-invasive monitoring.

To determine whether a model of transient mass-type brain damage (MTBD) in the rat produces early release of neurospecific enolase (NSE) and protein S100B in peripheral blood, as an expression of the induced brain injury. ⋯ Serum NSE and S100B concentrations offer an early indication of brain injury affecting the gray and white matter in an experimental model of mass-type MTBD in the rat.
