Intracranial aneurysm in patients with sickle cell disease is rare, but with an increased incidence in the recent years. This type of intracranial aneurysm possesses distinctive characteristics, and it has been the subject of case reports and series. ⋯ Intracranial aneurysms related to sickle cell disease mainly affected patients in their 20s, with a contradictory sex ratio in children and adults. Aneurysms manifested predisposition for multiplicity and posterior circulation. There was no difference between children and adults regarding shape and location of aneurysms. However, children with lower aneurysm rupturing rates had better outcomes than their adult counterparts did.

The use of hyperosmolar agents, such as mannitol or hypertonic saline (HTS), to control high intracranial pressure (ICP) in patients with traumatic brain injury has been well studied. However, the role of HTS in the management of aneurysmal subarachnoid hemorrhage (aSAH)-associated increased ICP is still unclear. ⋯ The current evidence suggests that HTS is as effective as mannitol at reducing increased ICP in aSAH. However, there is not enough data to recommend the optimal and safest dose concentration or whether HTS significantly improves outcomes in aSAH.

Although performing deep brain stimulation (DBS) with the patient under general anesthesia without microelectrode recording (MER) or intraoperative test stimulation (ITS) for movement disorders ("asleep" DBS) has become increasingly popular, its feasibility is based on the untested assumption that stereotactic accuracy correlates with positive clinical outcomes. To investigate outcomes after asleep DBS without MER or neurophysiological testing, we reviewed the medical literature on the topic. ⋯ Initial evidence suggests that asleep DBS can be performed safely for PD and ET with good clinical outcomes. Long-term follow-up, larger cohorts, and double-armed studies are needed to validate these initial results.

The prognosis in cervical spinal cord injury is poor, and surgical and neurointensive care management need further improvement. Monitoring of the intraspinal pressure (ISP) at an early stage after traumatic spinal cord injury (tSCI) is useful clinically. ⋯ A randomized controlled trial is required to determine whether laminectomy with durotomy and monitoring of ISP with SCPP optimization improve neurological recovery after tSCI.

Association of plasminogen activator inhibitor 1 (SERPINE1 gene) polymorphisms and aneurysmal subarachnoid hemorrhage.
Genetic variations of the serine proteinase inhibitor family E member 1 (SERPINE1) gene, which encodes plasminogen activator inhibitor 1, correlate with serum levels of its product and are associated with thrombophilia and coronary atherosclerosis. Various SERPINE1 ;gene polymorphisms have been identified. However, only the functional 5G/4G polymorphism has been assessed in the context of aneurysmal subarachnoid hemorrhage (aSAH). We assessed associations of 6 SERPINE1 polymorphisms with the clinical sequelae of aSAH. ⋯ SERPINE1 gene polymorphisms were associated with delayed cerebral ischemia and functional outcome after aSAH. These associations may arise from alterations of plasminogen activator inhibitor 1 levels.
