Abstract
Cerebral vasospasm (CVS) is a frequent and serious neurosurgical complication, without sufficient therapy. This retrospective study was performed to analyze if nimodipine can improve prognosis and reduce ischaemia secondary to delayed CVS after intracranial tumour surgery. A retrospective review was performed over the years 2011 to 2012 for patients with an anterior cranial fossa tumour and underwent intracranial tumour surgery. The surgical field was soaked with nimodipine solution or normal saline. Transcranial Doppler ultrasonography was used to measure velocity in the middle cerebral artery (MCA) and the distal extracranial internal carotid artery (eICA). Follow-up was performed using the Glasgow Outcome Scale (GOS) after discharge. There were 94 patients that met the inclusion criteria. They included 50 males and 44 females, with a mean age of 49.6 years. In the nimodipine group, CVS occurred in 13 patients; 9 patients had CVS between 4 and 7 days, and 4 had CVS between 8 and 14 days. In the normal saline group, 19 patients had CVS, 3 presented with CVS within 3 days, 11 between 4-7 days and 5 between 8-14 days. A significant difference in the occurrence of CVS was observed between the two groups. Preoperative and postoperative the MCA velocities were compared, revealing a significant change in the normal saline group but not in the nimodipine group. Nimodipine markedly improves prognosis and significantly reduces ischaemia secondary to delayed CVS after intracranial tumour surgery, as well as the risks of mortality and morbidity.

Abstract
Strokes are rare but severe accidents during pregnancy and post-partum period. They are responsible for high mortality and morbidity rates. Pre-eclampsia, eclampsia, and strokes are significantly related. Endothelial dysfunction, alteration of brain self-regulation and severe hypertension are, probably, the cause of many strokes in pregnant women and during postpartum period. We report a case of hemorrhagic stroke of the brainstem in a nonmonitored 21-year old patient at 38 weeks pregnant admitted with severe preeclampsia complicated by eclampsia and then by haemorrhagic stroke of the brainstem on the second post-operative day after cesarean section performed due to suspicion of retroplacental haematoma arisen since her admission. Intracerebral hemorrhage is a rare but severe complication in post-partum women. Several studies are underway to fill the gaps of knowledge involved in the management of pre-eclamptic patients with neurological complications.

Abstract
Background A variety of factors have been linked to perioperative visual loss during or directly after nonocular and ocular surgeries. Prolonged immobilization, biochemical factors and hemodynamic instability have been discussed as factors in the pathogenesis of this devastating complication. Perioperative visual loss in four consecutive patients, all featuring Flammer syndrome, is reported herein. To our knowledge, we present the first case series, which associates perioperative visual loss with Flammer syndrome. We assume that a low perfusion pressure, disturbed autoregulation of the ocular blood flow and altered drug sensitivity in such subjects, play significant role in the pathogenesis of this dreaded complication. Cases presentation We analysed the medical records of four consecutive patients with permanent perioperative visual loss and complemented our findings with additional history taking and clinical examinations. A variety of tests was performed, including colour Doppler ultrasonography of the retroocular vessels, static and dynamic retinal vessel analysis. The visual loss was unilateral in three patients and bilateral in one. An extensive review of published perioperative vision loss cases was conducted. All four patients were male Caucasians, and exhibited prominent signs and symptoms of Flammer syndrome. The visual loss originated from a propensity for unstable ocular blood flow, combined with hyperreactivity toward pharmacological stimuli, leading together to disturbed autoregulation of the blood supply, and subsequently - to ocular hypoxia. An identified intrinsic hypoperfusion diathesis was a crucial pathophysiologic link in all of the patients. Other, yet unknown systemic or local factors may also be involved in this process. Conclusions A review of numerous publications of perioperative visual loss and our data, support our hypothesis for a novel pathophysiologic model and incorporate Flammer syndrome as a distinct risk factor for paradoxical visual loss, during nonocular and ocular surgeries, or invasive procedures. To prevent the complications produced by disturbed blood flow autoregulation in such patients, guidelines for screening and tailored preoperative approach are given.

Abstract
Aneurysm subarachnoid hemorrhage affects 10 in 100,000 people annually, 40 % of whom will develop neurological deficits from ischemic stroke caused by cerebral vasospasm. Currently, the underlying mechanisms are uncertain. Metal ions are important modulators of neuronal electrophysiological conduction and smooth muscle cell activity, thereby potentially contributing to vasospasm. We hypothesized that metal ion concentrations in the cerebrospinal fluid (CSF) after aneurysm rupture would change over time and be associated with vasospasm. To test this hypothesis, for 21 days, we collected CSF from patients with aneurysmal rupture and subjected it to spectrometry to detect metals. A repeated measures analysis was performed to analyze concentration changes over time. Six of the seven patients with aneurysmal rupture experienced vasospasm, all resolving by day 14. Changes in Fe²⁺ and Zn²⁺ concentrations in the CSF paralleled the incidence of vasospasm in this study population. Na²⁺, Ca²⁺, Mg²⁺, and Cu²⁺ concentrations exhibited no statistically significant changes over time. In conclusion, Fe²⁺ concentration in the CSF was significantly elevated during days 7-10, whereas Zn²⁺ concentrations spiked shortly thereafter, during days 11-14. This suggests that Fe²⁺ may be related to the induction of vasospasm and Zn²⁺ may be a marker of early brain injury secondary to ischemic injury and inflammation.

Abstract
BACKGROUND AND PURPOSE Cerebral vasospasm resistant to medical management frequently requires intra-arterial spasmolysis. Angiographic resolution of vasospasm does not provide physiologic data on the adequacy of reperfusion. We recorded pre- and postspasmolysis PbO(2) data in the endovascular suite to determine whether this physiologic parameter could be used to determine when successful reperfusion was established. MATERIALS AND METHODS Eight patients with 10 Licox monitors and cerebral vasospasm underwent intra-arterial spasmolysis. Pre- and postspasmolytic PbO(2) was recorded for comparison. Other physiologic parameters, such as CPP, ICP, SaO(2), and Fio(2), were also recorded. RESULTS Mean prespasmolysis PbO(2) recordings were 35.2 and 27.3 for the mild-to-moderate and moderate-to-severe vasospasm group, respectively. Mean postspasmolysis PbO(2) increased to 40.3 and 38.4, respectively, which was statistically significant (P < .05) for both groups. In 100% of instances in the moderate-to-severe group and 83% of instances in mild-to-moderate group, the mean PbO(2) increased after spasmolysis and correlated with improvement in angiographic vasospasm. Other physiologic parameters, such as CPP, ICP, SaO(2), and Fio(2), did not show any statistically significant difference before and after spasmolysis. CONCLUSIONS PbO(2) monitoring provides the interventionalist with an objective physiologic parameter to determine adequate spasmolysis. Further investigation is needed to establish target PbO(2) rates indicative of adequate reperfusion, which can be used in the endovascular suite.

Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency that accounts for 5% of all stroke cases. Individuals affected are typically in the prime of their lives (mean age 50 years). Approximately 12% of patients die before receiving medical attention, 33% within 48 h and 50% within 30 days of aSAH. Of the survivors 50% suffer from permanent disability with an estimated lifetime cost more than double that of an ischemic stroke. Traditionally, spasm that develops in large cerebral arteries 3-7 days after aneurysm rupture is considered the most important determinant of brain injury and outcome after aSAH. However, recent studies show that prevention of delayed vasospasm does not improve outcome in aSAH patients. This finding has finally brought in focus the influence of early brain injury on outcome of aSAH. A substantial amount of evidence indicates that brain injury begins at the aneurysm rupture, evolves with time and plays an important role in patients' outcome. In this manuscript we review early brain injury after aSAH. Due to the early nature, most of the information on this injury comes from animals and few only from autopsy of patients who died within days after aSAH. Consequently, we began with a review of animal models of early brain injury, next we review the mechanisms of brain injury according to the sequence of their temporal appearance and finally we discuss the failure of clinical translation of therapies successful in animal models of aSAH.

Abstract
Acute neurological diseases requiring hospitalization are relatively rare in women of childbearing age. However, during pregnancy and the postpartum period, several diseases increase in prevalence. Some are unique to the pregnant/postpartum state including preeclampsia and delivery-associated neuropathies. Others, although indirectly related to pregnancy, such as cerebral venous thrombosis, ischemic stroke, and intracerebral hemorrhage, increase in frequency and carry considerable risk of morbidity and mortality. In addition, treatment options are often limited. This review discusses the diseases more commonly seen during pregnancy and the postpartum period, with a focus on emergent neurological diseases and their management. Interventional therapies will also be discussed.

Abstract
Cerebral vasospasm is a persistent arterial narrowing typically observed during the 3 - 14 days after subarachnoid hemorrhage (SAH). Vasospasm is frequently associated with ischemic neurological deficits or even death, resulting in a poor prognosis for patients with SAH. However, the mechanism underlying cerebral vasospasm remains elusive, and no effective therapeutic strategies have been established. A large amount of thrombin is produced during SAH. Recent investigations have uncovered a key role of the thrombin receptor in the pathogenesis of cerebral vasospasm. Thrombin has little contractile effect in the normal cerebral artery, but it induces an enhanced and prolonged contraction after SAH, owing to the up-regulation of thrombin receptor PAR(1) (proteinase-activated receptor 1) and the impairment of receptor desensitization in arterial smooth muscle. Thrombin-mediated activation of PAR(1) is an irreversible process, as it is initiated by the proteolytic removal of the N-terminal region. Since the mechanism of receptor desensitization is impaired after SAH, the thrombin-induced contraction irreversibly persists even after terminating thrombin stimulation. Intrathecal administration of a PAR(1) antagonist prevents the PAR(1) up-regulation and the increased reactivity to thrombin. PAR(1) is suggested to play a key role in cerebral vasospasm and may be useful as a therapeutic target for prevention and treatment of cerebral vasospasm.

Abstract
PURPOSE Our objective was to study the effects of polymorphic the CYP3A5 (allele *1 and *3), MDR1 [single nucleotide polymorphisms (SNPs) G2677T, C3435T] and CACNA1C (SNPs rs2239128, rs2239050, rs2238032) genes on nimodipine oral disposition and response in healthy Chinese subjects. METHODS Pharmacokinetics and pharmacodynamics data were obtained from a bioequivalence study, and the same 20 subjects were genotyped for CYP3A, MDR1 and CACNA1C. An additional 41 healthy Chinese subjects were recruited to obtain an indication of the distribution of CACNA1C polymorphisms in the Chinese population. Racial differences in the frequency of CACNA1C alleles were assessed. The phenotype differences between genotypes were analyzed. RESULTS The allelic frequencies of rs2239050 and rs2238032 in our Chinese cohort were different from those in a Caucasian population (p < 0.01). Subjects with mutant alleles (*3/*3) of the CYP3A5 gene had a decreased oral clearance of nimodipine, with a higher lnC(max) or 1n AUC(0-infinity) compared with those subjects with the heterozygote (*1/*3) or wild type (*1/*1) gene. The CACNA1C rs2239128 C and rs2239050 G SNPs were associated with a stronger efficacy compared with their respective alleles, rs2239128 T and rs2239050 C. MDR1 polymorphisms showed no significance in terms of nimodipine disposition. CONCLUSIONS The polymorphic CYP3A5 (allele *1 and *3) and CACNA1C genes have effects on nimodipine oral disposition and response in healthy Chinese subjects. The homozygous variant of CYP3A5 (*3/*3) was associated with significantly increased nimodipine exposure. CACNA1C SNPs rs2239128 C and rs2239050 G were associated with a stronger efficacy.
