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.

Intrathecal baclofen is widely accepted as a treatment option for severe spasticity through its γ-Aminobutyric acid-B (GABAB ) agonist properties. Abrupt cessation can lead to severe and life-threatening withdrawal characterized by altered mental status, autonomic dysreflexia, rigidity, and seizures. This symptomatic presentation is similar to alcohol withdrawal, which is mediated by modification of GABAA expression. Use of the α2-adrenergic agonist dexmedetomidine for the treatment of ethanol withdrawal has been widely reported, raising the question of its potential role in baclofen withdrawal. We present a case of the successful treatment of acute severe baclofen withdrawal with a dexmedetomidine infusion. ⋯ Dexmedetomidine is to our knowledge a previously unreported option for treatment of acute severe baclofen withdrawal. We report a case of safe and efficacious use in a patient with spastic quadriparesis on chronic intrathecal baclofen. Scientifically rigorous comparison with other options remains to be performed.

Review Case Reports
A Cause of Atypical Intracranial Subarachnoid Hemorrhage: Posterior Spinal Artery Aneurysms.
Approximately 1 % of cases of intracranial subarachnoid hemorrhage (SAH) are caused by spinal vascular pathologies. Among them, isolated spinal artery aneurysms are uncommon and a limited number of cases have been reported in the literature. ⋯ Isolated spinal artery aneurysms represent a rare cause of intracranial SAH. Symptoms such as back pain and lower-extremity weakness can be clues to the adequate diagnosis. Surgical or endovascular treatment should be pursued in all patients, as the risk of rebleeding is non-negligible.

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.
