Randomized Controlled Trial
Determinants of effective cooling during endovascular hypothermia.
Therapeutic hypothermia is a promising neuroprotective therapy with multiple mechanisms of action. We demonstrated the feasibility of thrombolysis combined with endovascular hypothermia, but not all patients achieved effective cooling. We sought to identify the factors that determined effective cooling. ⋯ The most important determinant of effective cooling during endovascular hypothermia is BSA; larger patients are more difficult to cool and maintain in therapeutic range. Older patients cool more quickly. Shivering was well controlled by the combination of meperidine, buspirone, and surface counter-warming and only minimally influenced cooling effectiveness. Future trials of therapeutic hypothermia may include added measures to cool larger patients more effectively.

Recent advances in medicine, intensive care and diagnostic imaging modalities have led to a pronounced reduction in deaths and disability resulting from traumatic brain injury. However, there are not sufficient findings to evaluate and quantify the severity of the initial and secondary processes destructive and therefore there are not effective therapeutic measures to effectively predict the outcome. ⋯ Usually, the levels of these proteins increase following brain injury and are found in increasing concentrations in the cerebrospinal fluid depending on the injury magnitude, and can also be found in blood stream because of a compromised blood-brain barrier. In this review, we examine the various factors that must be taken into account in the search for a reliable non-invasive biomarkers in traumatic brain injury and their role in the diagnosis and outcome evaluation.

To evaluate clinical features and prognostic factors of cerebral infarctions in adults with community-acquired bacterial meningitis. ⋯ Cerebral infarction is a common and severe complication in adults with community-acquired bacterial meningitis. Preventing cerebral infarctions will be important in reducing the high morbidity and mortality rate in adults with community-acquired bacterial meningitis.

Comparative Study
Retrospective evaluation of nicardipine versus labetalol for blood pressure control in aneurysmal subarachnoid hemorrhage.
American Heart Association/American Stroke Association guidelines for management of aneurysmal subarachnoid hemorrhage (aSAH) recommend blood pressure (BP) control, utilizing labetalol or nicardipine, but do not differentiate efficacy between the two agents. The purpose of this retrospective study was to compare BP control between labetalol and nicardipine in patients following aSAH. ⋯ Our study showed nicardipine to be associated with superior BP control versus labetalol in aSAH.

Complications of coronary artery bypass graft surgery (CABG) include acute oculomotor nerve palsy secondary to ischemic stroke and pituitary apoplexy. These can present with impairment of extraocular muscle function as well as involvement or sparing of the pupil. ⋯ Acute pupil-sparing partial oculomotor nerve palsy should be recognized as a neurological complication of cardiac surgery. Pupillary involvement can be helpful in identifying the underlying etiology.
