In the last five decades a continuous increase in the average global temperature has been recorded. Furthermore, natural disasters (e.g. heat waves, severe storms, floods and large forest fires) are becoming more frequent. The impact of global warming and climate change on health involves an increase in respiratory, cardiovascular, renal and cognitive mental diseases. Furthermore, a change in the frequency and patterns of infectious diseases can also be observed in Europe. ⋯ Intensive care medicine must be prepared for the challenges due to global warming and climate change. Slow but continuous changes (e.g. rise in temperature) as well as acute changes (e.g. heat waves and natural disasters) will induce an increased need for intensive medical care services (e.g. an increase in the need for renal replacement procedures). Intensive care physicians will need to be familiar with the diagnostics and management of diseases associated with the climate change. An initiative of the specialist societies involved would be welcomed.

A 58-year-old woman developed rapidly progressive neurological symptoms and finally loss of vigilance 5 weeks following primarily successful lung transplantation. A posterior reversible encephalopathy syndrome (PRES) under treatment with tacrolimus as well as hyperammonemia due to sepsis with Ureaplasma urealyticum could be identified as the causes. Infections with Ureaplasma, bacteria which produce ammonia as a product of metabolism, are increasingly being identified in immunocompromised people by specific PCR (polymerase chain reaction) procedures and should routinely be taken into consideration as the cause of unspecific neurological symptoms.

Observational Study
[Ultrasound visualization of the guidewire and positioning of the central venous catheter : A prospective observational study].
After insertion of a central venous catheter (CVC) the catheter position must be controlled and a pneumothorax ruled out. ⋯ The presented intraprocedural ultrasound-based method using two standard acoustic windows is reliable for verification of the correct intravenous location and direction of the guidewire even before dilatation of the vessel puncture site for insertion of the catheter. Furthermore, the method allows the clinically acceptable measurement of the required length for catheter positioning. A chest radiograph can be waived provided the ultrasound examination (identification of the guidewire and exclusion of puncture-related complications such as pneumothorax) is unambiguous.
