Obesity leads to better survival in critically ill patients. Although there are several studies confirming this thesis, the "obesity paradox" is still surprising from the clinician's perspective. One explanation for the "obesity paradox" is the fact that the body mass index (BMI), which is used in almost all clinical evaluations to determine weight categories, is not an appropriate measure of fat and skeletal muscle mass and its distribution in critically ill patients. ⋯ For future clinical observation or interventional studies, single cross-sectional CT is a more sophisticated tool for measuring patients' anthropometry than a measuring tape and callipers. Patients with sarcopenic obesity, for example, who may be at a particular risk, can only be identified using imaging procedures such as single cross-sectional CT. Thus, BMI should take a back seat as an anthropometric tool, both in the clinic and in research.

The external post-mortem examination in Germany is a non-delegable medical duty for determination of death, identity of the deceased, cause of death, manner of death, time of death and notifiable infectious diseases. Within the framework of rescue service missions the physician is limited to ascertaining that death has occurred. The determination of death must be reliable and is automatically followed by a complete external post-mortem examination of the body, if necessary by another physician. ⋯ Reliable features for the occurrence of death are injuries which are not compatible with life and brain death. The external post-mortem examination is the basis for the decision on whether further criminal investigations are necessary. The external post-mortem examination and the accompanying death certification must always be meticulously carried out.
