Clinical Trial
[Management of dysphagia in acute stroke : A prospective study for validation of current recommendations].
The German expert recommendations on the management of dysphagia in patients after acute stroke suggest an algorithm for clinical and technical investigations to identify patients at risk for aspiration and thus reduce the rate of aspiration pneumonia. The effectiveness of this algorithm has, however, not yet been prospectively validated . ⋯ Clinical screening alone is not sufficient to identify patients at risk for aspiration pneumonia. The FEES should be used at a low threshold in cases of severe stroke and minor clinical abnormalities, especially concerning isolated dysarthria and cough after swallowing water; therefore, current recommendations should be correspondingly modified.

To this day the definite diagnosis of Alzheimer's disease still relies on post-mortem histopathological detection of neurofibrillary tangles and beta-amyloid deposits. Amyloid positron emission tomography (PET) is a new diagnostic tool that enables the in vivo quantification of pathological beta-amyloid deposits. The aim of the current study was to evaluate to what extent 18F-florbetaben-PET (FBB-PET) influences the diagnosis of patients with dementia. ⋯ Amyloid-PET is currently no standard procedure in the diagnosis of dementia; however, it can be a helpful additional diagnostic tool when used according to the "Appropriate Use Criteria" and the S3 guidelines on dementia in cases of unclear clinical presentation, atypically early age of onset as well as in patients with persistent or progressive unexplained mild cognitive impairment. By facilitating early diagnosis amyloid-PET imaging allows patient selection for therapeutic drug trials.
