Multicenter Study
Prediction of poor outcome within the first 3 days of postanoxic coma.
To determine the optimal timing of somatosensory evoked potential (SSEP) recordings and the additional value of clinical and biochemical variables for the prediction of poor outcome in patients who remain comatose after cardiopulmonary resuscitation (CPR). ⋯ Poor outcome in postanoxic coma can be reliably predicted with somatosensory evoked potentials and neuron-specific enolase as early as 24 hours after cardiopulmonary resuscitation in a substantial number of patients.

Comparative Study
Patterns of atrophy in pathologically confirmed FTLD with and without motor neuron degeneration.
The authors used voxel-based morphometry to compare the patterns of brain atrophy in two variants of pathologically confirmed frontotemporal lobar degeneration (FTLD): FTLD with motor neuron disease (FTLD-MND) and FTLD with ubiquitin-only-immunoreactive neuronal changes (FTLD-U). Patterns of atrophy were distinct and different from each other. A localized pattern of frontal lobe atrophy was found in FTLD-MND with a more widespread pattern of atrophy affecting the frontal and temporal lobes in FTLD-U.

Mexican Americans (MAs) have higher incidence rates of intracerebral hemorrhage (ICH) than non-Hispanic whites (NHWs). The authors present clinical and imaging characteristics of ICH in MAs and NHWs in a population-based study. ⋯ There are significant differences in the characteristics of ICH in MAs and NHWs, with MA patients more likely to have smaller, nonlobar hemorrhages. These differences may be used to examine the underlying pathophysiology of ICH.

The authors studied 14 patients with an isolated cerebellar infarct in the territory of the medial branch of the superior cerebellar artery (MSCA). The most common clinical finding was severe gait ataxia with sudden falling (n = 9) or severe veering (n = 2). ⋯ Eight patients had a mild unilateral limb ataxia. These findings emphasize that MSCA territory cerebellar infarction presented with the prominent gait ataxia and cerebellar dysarthria.
