Preventive approaches in the field of Alzheimer disease (AD) is important but these trials raise many questions. Which protective factor should be studied? What population should be studied? With which principal and secondary criteria? We present here the design of the ongoing GuidAge Study. In the past, several studies suggest that Ginkgo biloba could have a potential benefit effect on cognitive function. The aim of the GuidAge Study is to evaluate the efficacy of 240 mg/d of EGb 761 in the prevention of AD. ⋯ The GuidAge study is the largest study carried out in Europe on the prevention of AD. Final results should be available in 2010.

To review evidence on the assessment of the child with status epilepticus (SE). ⋯ Although common clinical practice is that blood cultures and lumbar puncture are obtained if there is a clinical suspicion of a systemic or CNS infection, there are insufficient data to support or refute recommendations as to whether blood cultures or lumbar puncture should be done on a routine basis in children in whom there is no clinical suspicion of a systemic or CNS infection (Level U). AED levels should be considered when a child with treated epilepsy develops SE (Level B). Toxicology studies and metabolic studies for inborn errors of metabolism may be considered in children with SE when there are clinical indicators for concern or when the initial evaluation reveals no etiology (Level C). An EEG may be considered in a child with SE as it may be helpful in determining whether there are focal or generalized epileptiform abnormalities that may guide further testing for the etiology of SE, when there is a suspicion of pseudostatus epilepticus (nonepileptic SE), or nonconvulsive SE, and may guide treatment (Level C). Neuroimaging may be considered after the child with SE has been stabilized if there are clinical indications or if the etiology is unknown (Level C). There is insufficient evidence to support or refute routine neuroimaging in a child presenting with SE (Level U).
