Review Meta AnalysisDiagnostic accuracy of 18 F-FDG and 11 C-PIB-PET for prediction of short-term conversion to Alzheimer's disease in subjects with mild cognitive impairment.
In recent years, the role of PET imaging in the prediction of mild cognitive impairment (MCI) to Alzheimer's disease (AD) conversion has been the subject of many longitudinal studies. The purpose of this study was to perform a meta-analysis to estimate the diagnostic accuracy of (18) F-fluoro-2-deoxyglucose-positron emission tomography (FDG-PET) and (11) C-Pittsburgh Compound B-positron emission tomography (PIB-PET) for prediction of short-term conversion to AD in patients with MCI. The MEDLINE and EMBASE databases were systematically searched for relevant studies. ⋯ The data from FDG-PET research studies had high heterogeneity and funnel plot suggested a publication bias. The diagnostic accuracy determined for both FDG-PET and PIB-PET in this meta-analysis suggests that they are potentially valuable techniques for prediction of progression in patients with MCI. Both have their advantages and their combined use is a promising option for prediction purposes depending on availability and experience.

ReviewMeniere's disease: an evidence based approach to assessment and management.
Menière's disease (MD) is frequently over-diagnosed in both primary and secondary care. This is unfortunate given the significant medical and social implications of such a diagnosis. Difficulties may arise in differentiating the patient with true MD from those individuals with less clearly defined disorders of cochleo-vestibular function. In this review, we suggest a practical evidence based approach to assessment and management of the patient with MD.
