The term acute kidney injury (AKI) has been recently coined by a large panel of international experts in place of the former expression "acute renal failure". This change has been motivated by a double intention: first it served to definitely find a conventional definition for acute changes of renal function, previously lacking in the medical community. ⋯ The second aim was to remark that this syndrome is characterised by a spectrum of progressive damage, from mild creatinine increase to renal injury to a more severe form, failure: this important concept should increase clinicians awareness to every form of renal dysfunction, even milder ones, in order to improve epidemiologic analyses, potentially preventing eventual AKI progression and finally helping standardisation of medical and supportive therapy. This review will describe such "new era" of critical care nephrology by presenting current literature (and its many controversies) about AKI diagnosis, physiopathology and management.

Although safety and efficacy of TAVI was improved with next-generation equipment, experience, and careful patient selection, some worrisome complications associated with the procedure remain. Current hot topics in transcatheter aortic valve implantation include patient selection, valve sizing, paravalvular regurgitation, cerebrovascular accidents, vascular complications and need for a permanent pacemaker. In this article we review the pathophysiology, avoidance and treatment options for these complications.

Multicenter StudyCost of attempted suicide: a retrospective study of extent and associated factors.
Suicidal behaviour is a major source of burden of disease. While most studies focus on cost associated with completed suicides, data on costs of, non-lethal, suicide attempts are lacking. The aim of this study was to assess direct annual cost of suicide attempts in Basel in 2003 from a health services perspective. ⋯ Attempted suicide produces substantial direct medical costs, which are only a part of the financial burden. Prevention targeting mood disorders, the elderly and the use of hard methods may be most cost-effective. Further research should aim at identifying additional indirect costs and the cost-effectiveness of prevention measures.

ReviewControversies in the determination of death: perspectives from Switzerland.
In 1968, an Ad Hoc committee at the Harvard Medical School advanced new criteria for determining death. It proposed that patients in irreversible coma with no discernible central nervous system activity were actually dead. ⋯ Despite this, the philosophical and ethical debate about the "whole brain" definition of death is far from being closed. This paper analyses the ongoing controversy and evaluates the recent revision of the Swiss Academy of Medical Sciences guidelines for determining death.

This opinion article has been written on request because of the recent public controversy over silicone breast implants produced by a now-defunct company, Poly Implant Prosthese (PIP) in France. More than 300,000 PIP devices have been implanted. The purposes of my article are to (1.) provide a general overview of silicone breast implant materials, (2.) to describe the general safety of these materials as reported to date, and (3.) to summarise current publicly available information about these aspects of the PIP prostheses. ⋯ Initial regulatory disclosures suggest the PIP implants may have both biocompatibility and biodurability problems. They also suggest that PIP implants may have been produced using silicone materials not certified as medical grade. Governmental health and regulatory agencies are just now in the process of deciding what actions should be taken to protect patients.
