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.

Review
The Role of Neuromuscular Blockade in Patients with Traumatic Brain Injury: A Systematic Review.
Management of Traumatic Brain Injury (TBI) focuses on controlling intracranial pressure (ICP), while other treatments, such as the use of neuromuscular blocking agents (NMBAs), need scientific evidence. We conducted a systematic review to investigate the usefulness of NMBAs in the context of TBI and/or increased ICP. We searched MEDLINE and EMBASE databases up to January 31st 2014, including both clinical and experimental findings. ⋯ However, retrospective evidence found potential harm by continuous NMBA infusion. In the context of TBI patients, we discuss the potentially positive effects of paralysis with its negative ones. Well-conducted randomized controlled trials and/or large pharmaco-epidemiologic studies are warranted.
