Detecting and treating elevated intracranial pressure (ICP) is a cornerstone of management in patients with severe traumatic brain injury. The aim of this study was to determine the association between area under the curve measurement of elevated ICP and clinical outcome. ⋯ These results suggest that pressure time dose measurement of intracranial pressure may be used to predict outcome in severe traumatic brain injury and may be a candidate biomarker in this disease.

A study performed in Hong Kong of catheter angiography after ICH found a high rate of structural lesions in patients 45 years of age or younger, without a history of hypertension, or with lobar hemorrhage. We hypothesized that a clinical decision rule based on these Hong Kong criteria would reliably identify patients who require MRI after ICH. ⋯ A rule based on simple clinical criteria may be useful for stratifying the yield of MRI after ICH. If validated in further studies, such a rule could reduce the number of unnecessary MRI studies after ICH, leading to more cost-effective care.

Fever and hematoma growth are known to be independent predictors of poor outcome after intracerebral hemorrhage (ICH). We sought to assess the distribution of temperature at different stages in relation to hematoma growth and functional outcome at 90 days in a cohort of ICH patients. ⋯ There is a temporal and independent association between fever and hematoma growth. Fever after ICH is associated with poor outcome at 90 days. Future research is needed to study the mechanisms of this phenomenon and if early protocols of temperature modulation would be associated with improved outcomes after ICH.

Vasospasm may occur following intracranial tumor resection but is uncommon following resection of tumors in the posterior fossa. ⋯ This case illustrates an unusual complication of posterior fossa tumor resection, and the potential utility of TCD studies in the detection and management of vasospasm in pediatric neurocritical care.

Clinical prediction models can enhance clinical decision-making and research. However, available prediction models in aneurysmal subarachnoid hemorrhage (aSAH) are rarely used. We evaluated the methodological validity of SAH prediction models and the relevance of the main predictors to identify potentially reliable models and to guide future attempts at model development. ⋯ While clinical prediction models for aSAH use a few simple predictors, there are substantial methodological problems with the models and none have had external validation. This precludes the use of existing models for clinical or research purposes. We recommend further studies to develop and validate reliable clinical prediction models for aSAH.
