[Retrospective analysis of routine-MRI and correlation with aetiology of dementia, severity and neuropsychology in a memory-clinic population].
The contribution of potential treatable dementia aetiologies diagnosed using cerebral imaging varied considerably in previous studies and was not evaluated in a recent larger German sample of patients from a memory clinic. ⋯ In 9 % there was a clear discrepancy between MRI results and the clinical syndrome diagnosis in memory-clinic patients. As known from earlier studies and current German 3 rd generation guidelines, it is reasonable to perform MRI imaging in dementia to improve the aetiological and differential diagnoses and to detect a different aetiology that can be missed using the clinical dementia criteria alone.

The brain is composed of two major cell types - neurons and glial cells. While neurons have been extensively studied, research on glia cells has picked up only in the last decades. There are three types of glia cells in the central nervous system: astrocytes, oligodendrocytes and microglia cells. ⋯ They migrate to the site of injury, can proliferate and phagocytose and interact with the peripheral immune system by antigen presentation. Today, we view the brain as an organ which fulfils its function by the interaction of all these cell types. This is also particularly relevant for brain diseases.

In a survey of American and German medical personnel, the injectable hypnotic propofol was identified as one of the most frequently abused anaesthetics. With the help of MEDLINE, EMBASE, Scopus, Cochrane and internet search, data were sought that permit an assessment of propofol's risk of addiction. The clinical evaluation for hypnotics can usually be made with the scale of Griffith and Johnson. ⋯ Forensic analyses consider mainly accidental respiratory arrests to be responsible for the deaths. In summary, propofol is considered to be a primary mental addictive substance that is characteristically intravenously consumed by persons within the medical profession. Because of its apparently narrow safety margin between pleasure and death, propofol is an extraordinary hazard which, unfortunately, is only reflected insufficiently in the scale of Griffith and Johnson.

[Whiplash and Werther effect: the potential of google insights for search for medical research and public health].
Illness behaviour involves cultural, situational and personal predispositions. World Wide Web search statistics provided by internet applications like Google Insights for Search have the potential to facilitate our research on the distribution of mental disorders, our understanding of both sociocultural imprintings and trends in psychophenomenology and could make a remarkable contribution to medical research and public health.
