Contrast extravasation (CE) in spontaneous intracerebral hemorrhage (ICH), coined the spot sign, predicts hematoma expansion (HE) and poor clinical outcome. The dynamic relationship between CE and the mode of ICH growth are poorly understood. We characterized the in vivo pattern and rate of HE using a novel animal model of acute ICH. ⋯ A novel model of ICH provides real-time study of the dynamics and rate of CE. This data facilitates the understanding of pattern and rate of ICH formation.

Multicenter Study Observational Study
Predictors of Nosocomial Pneumonia in Intracerebral Hemorrhage Patients: A Multi-center Observational Study.
Nosocomial pneumonia (NP) is a frequent complication among spontaneous intracerebral hemorrhage (sICH) patients. This study was aimed at identifying in-hospital risk factors that predispose sICH patients to NP. ⋯ Independent predictors of NP included early hospital admission, in-hospital aspiration, intubation, and tracheostomy. NP was associated with prolonged hospital LOS.

Review Case Reports
Dialysis-Induced Worsening of Cerebral Edema in Intracranial Hemorrhage: A Case Series and Clinical Perspective.
Intracranial hemorrhage (ICH) is not an uncommon complication of end-stage renal disease (ESRD), and may be complicated by cerebral edema. Hemodialysis (HD) may induce rapid osmolar and fluid shifts, increasing brain water content with the potential to worsen cerebral edema. The dangers of HD in patients with acute ICH have only been highlighted in isolated reports. ⋯ Hemodialysis may worsen cerebral edema in the setting of ICH sufficient to precipitate cerebral herniation. Caution should be exercised when dialysing a patient with an acute mass lesion and reduced intracranial compliance, especially those in whom HD is new or not routine. Delaying HD till risk of edema is attenuated, or ensuring gradual urea removal (such as with continuous hemofiltration) may be advisable.

Status epilepticus (SE) is a neurological emergency with high mortality and often a poor functional outcome amongst survivors. So far, only status epilepticus severity score (STESS) is available to predict individual outcomes. STESS is based on weighted sum scores of age, type of seizure, level of consciousness and history of previous seizures. Weighting factors were based on a priori assumptions. ⋯ EMSE explained individual mortality in almost 90 % of cases, and performed significantly better than previous scores. This explorative study needs external prospective corroboration. EMSE may be a valuable tool for risk stratification in interventional studies in the future.
