The ISAT and ISUIA studies, along with the improvement of endovascular treatment (EVT) have strongly influenced the management of intracranial aneurysms (IAs). We present our experience in the microsurgical treatment of unruptured IAs (UIAs) in this context. ⋯ Despite reduction in operative cases and in appropriately selected patients ineligible to EVT, microsurgical clipping of non-giant anterior circulation UIAs can still achieve good outcome with very low mortality and neurological morbidity.

Awake brain surgery is useful for the treatment of a number of conditions such as epilepsy and brain tumor, as well as in functional neurosurgery. Several studies have been published regarding clinical results and outcomes of patients who have undergone awake craniotomy but few have dealt with related ethical issues. ⋯ The authors respectfully suggest that the selection of patients for awake craniotomy needs to be monitored according to more consistent, objective standards in order to avoid conflicts of interest and potential harm to patients.

Brain biopsy plays a crucial role in the exploration of suspect white matter lesions in the differential diagnosis of primary central nervous system lymphoma (PCNSL) and inflammatory demyelination. We present the case of a previously healthy, immunocompetent woman, aged fifty-nine, who developed a histologically confirmed demyelinating white matter lesion months prior to the manifestation of a PCNSL. ⋯ In a literature review, we compared the diagnostic features that may be useful to differentiate a PCNSL from inflammatory demyelinating disease in older age. We conclude that the occurrence of large, contrast-enhancing cerebral lesions in older patients with a relapsing-remitting disease course and steroid-resistant vision disorders should lead to the consideration of a PCNSL.

Administering analgesics, sedatives and antipsychotics is challenging in the Neurological Intensive Care Unit (NICU). We reviewed this literature and our current practice to better inform the critical care practitioner and to identify gaps for future research. We electronically searched observational, intervention and outcome studies addressing sedation, analgesia and delirium in the NICU, and their bibliographies. ⋯ Clearly, little information exists on analgesia, sedation and delirium in the NICU. Systematic evaluation of pain improves outcome. No evidence-based therapeutic recommendations can be proffered.

The American Academy of Neurology recommended using phenytoin or carbamazepine to prevent early post-traumatic seizures (PTS) in severe traumatic brain injuries (TBI). In this study, we examined the effects of using phenytoin prophylaxis on mild, moderate, and severe TBIs. There have been no studies looking at compliance rate and side effects of systematic use of phenytoin at a large population scale. The goal of this study is to determine 1) the proportion of TBI patients receiving phenytoin prophylaxis; 2) which parameters decided when to decide administer phenytoin; 3) prophylaxis efficacy and complication rate. ⋯ Phenytoin is used according to guidelines, with CT scan being the main decision factor for its use. The frequency of early PTS rate is low and side effects are rare. However, earlier administration of phenytoin and adequate levels could further prevent early PTS.
