Comparative Study
Standardized protocols increase organ and tissue donation rates in the neurocritical care unit.
The authors tested the effect of uncoupling and removal of the treating physician from organ and tissue donation requests on consent rates for donation in the neurocritical care unit. After a neurointensivist-led policy change, consent rates increased from 23.1 to 36.5% (odds ratio = 1.9, p = 0.01), whereas there was no change in other hospital units. This supports such a policy change and shows a positive effect of a neurointensivist on organ and tissue procurement.

To examine the association between diabetes in midlife (1963-1968) and dementia more than three decades later (1999-2001). ⋯ Evidence for diabetes as a risk factor for dementia was found, similar to other epidemiologic studies. In contrast to the earlier studies, however, the authors linked diabetes in midlife to dementia more than three decades later in the very old survivors of a large male cohort.

Thirty patients with a typical orthostatic headache were treated by early lumbar epidural blood patch (EBP) without previously performing lumbar puncture or identifying a CSF leak and with or without typical MRI changes. A complete cure was obtained in 77% of patients after one (57%) or two (20%) EBPs. Spontaneous intracranial hypotension with typical orthostatic headache can be diagnosed without lumbar puncture and can be cured by early EBP in a majority of patients.

To investigate cerebral activity associated with allodynia in patients with neuropathic pain. ⋯ On a background of deafferentation in the hemisphere contralateral to stimuli, enhanced or additional responses to innocuous stimuli in the ipsilateral hemisphere may contribute to the shift of perception from innocuous toward painful and ill-defined sensations.
