Abstract
OBJECTIVE To report the short-term (1 year) and long-term (5 years) outcome of patients with Parkinson's disease (PD) with subthalamic nucleus (STN) stimulation operated upon under controlled general anaesthesia (GA). METHODS 213 consecutive patients with PD were included between January 2000 and March 2009 and operated upon under a particular type of GA with close control of the level of sedation allowing intraoperative recordings. 188 patients were assessed 1 year postoperatively. 65 patients also completed the long-term observation period and were evaluated 5 years postoperatively. RESULTS The Unified PD Rating Scale III score in the 'Off drug--On stim' condition was improved at 1 year and 5 years by 61% and 37%, respectively, (p<0.001). Motor complications decreased at short-term and long-term by 68% and 65%, respectively, for dyskinesia and by 52% and 48%, respectively, for fluctuations, (p<0.001). Dopaminergic treatment could also be reduced at short-term and long-term by 46% and 49%, respectively (p<0.001). There was no significant modification of mood and cognition assessments (Mattis scale and Beck depression inventory) at 1 year and 5 years. Concerning the main adverse events related to the surgery, we report four haematomas (1.9%) with two deaths (0.9%), eight cases of transient confusion (3.7%) and no epileptic seizure. CONCLUSIONS Our results confirm that STN stimulation performed under controlled GA is efficient and has similar short-term and long-term motor effects than intervention under local anaesthesia. Furthermore, this specific procedure is not associated with more adverse events. The success of such an intervention requires strict anaesthetic monitoring and accurate STN identification.

Abstract
Candida albicans or non-albicans are a frequent source of infection but seldom displayed in cerebrospinal fluid although responsible of an important number of nosocomial meningitis. Diagnosis is difficult which often delays treatment, which in turn hinders prognostic. This clinical case shows a patient afflicted with a deadly C. albicans meningitis and allows us to focus on new diagnostic tools and advice against this infection.

Abstract
BACKGROUND In patients with severe sepsis, no randomized clinical trial has tested the concept of de-escalation of empirical antimicrobial therapy. This study aimed to compare the de-escalation strategy with the continuation of an appropriate empirical treatment in those patients. METHODS This was a multicenter non-blinded randomized noninferiority trial of patients with severe sepsis who were randomly assigned to de-escalation or continuation of empirical antimicrobial treatment. Recruitment began in February 2012 and ended in April 2013 in nine intensive care units (ICUs) in France. Patients with severe sepsis were assigned to de-escalation (n = 59) or continuation of empirical antimicrobial treatment (n = 57). The primary outcome was to measure the duration of ICU stay. We defined a noninferiority margin of 2 days. If the lower boundary of the 95 % confidence interval (CI) for the difference in patients assigned to the de-escalation group was less than 2 days, as compared with that of patients assigned to the continuation group, de-escalation was considered to be noninferior to the continuation strategy. Secondary outcomes included mortality at 90 days, occurrence of organ failure, number of superinfections, and number of days with antibiotics during the ICU stay. RESULTS The median duration of ICU stay was 9 [interquartile range (IQR) 5-22] days in the de-escalation group and 8 [IQR 4-15] days in the continuation group, respectively (P = 0.71). The mean difference was 3.4 (95 % CI -1.7 to 8.5). A superinfection occurred in 16 (27 %) patients in the de-escalation group and six (11 %) patients in the continuation group (P = 0.03). The numbers of antibiotic days were 9 [7-15] and 7.5 [6-13] in the de-escalation group and continuation group, respectively (P = 0.03). Mortality was similar in both groups. CONCLUSION As compared to the continuation of the empirical antimicrobial treatment, a strategy based on de-escalation of antibiotics resulted in prolonged duration of ICU stay. However, it did not affect the mortality rate.

Abstract
INTRODUCTION Recent data on newborn animals exposed to anesthetics have raised safety concerns regarding anesthesia practices in young children. Indeed, studies on rodents have demonstrated a widespread increase in brain apoptosis shortly after exposure to sevoflurane, followed by long-term neurologic impairment. In this context, we aimed to evaluate the protective effect of rh-EPO, a potent neuroprotective agent, in rat pups exposed to sevoflurane. MATERIAL AND METHODS At postnatal day 7, 75 rat pups were allocated into three groups: SEVO + EPO (n = 27) exposed to sevoflurane 2 vol% (0.5 MAC) for 6 h in an air/O2 mixture (60/40) + 5000 UI.kg(-1) rh-EPO IP; SEVO (n = 27) exposed to sevoflurane + vehicle IP; and CONTROL (n = 21) exposed to the mixture without sevoflurane + vehicle IP. Three days after anesthesia (D10), apoptosis was quantified on brain extract with TUNEL method and caspase 3. NGF and BDNF expression was determined by Western blotting. Rats reaching adulthood were evaluated in terms of exploration capacities (object exploration duration) together with spatial and object learning (water maze and novel object test). RESULTS Sevoflurane exposure impaired normal behavior in adult rats by reducing the exploratory capacities during the novel object test and impaired both spatial and object learning capacities in adult rats (water maze, ratio time to find platform 3rd trial/1st trial: 1.1 ± 0.2 vs 0.4 ± 0.1; n = 9, SEVO vs CONTROL; P = 0.01). Rh-EPO reduced sevoflurane-induced behavior and learning abnormalities in adult rats (water maze, ratio time to find platform 3rd trial/1st trial: 0.3 ± 0.1 vs 1.1 ± 0.2; n = 9, SEVO + EPO vs SEVO; P = 0.01). Three days after anesthesia, rh-EPO prevented sevoflurane-induced brain apoptosis (5 ± 3 vs 35 ± 6 apoptotic cells·mm(-2) ; n = 6, SEVO + EPO vs SEVO; P = 0.01) and elevation of caspase three level and significantly increased the brain expression of BDNF and NGF (n = 6, SEVO + EPO vs SEVO; P = 0.01). CONCLUSION Six hours of sevoflurane anesthesia in newborn rats induces significant long-term cognitive impairment. A single administration of rh-EPO immediately after postnatal exposure to sevoflurane reduces both early activation of apoptotic phenomenon and late onset of neurologic disorders.

Abstract
BACKGROUND Most patients are anxious before surgery. The level of preoperative anxiety depends on several factors and merits an objective evaluation. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a self-report questionnaire comprising six questions that have been developed and validated to evaluate the preoperative anxiety of patients. This global index assesses three separate areas: anxiety about anaesthesia, anxiety about surgery, and the desire for information. The purpose of this study was to translate the APAIS into French and to evaluate the psychometric properties of the French version of the APAIS. METHODS The process consisted of two steps. The first step involved the production of a French version of the APAIS that was semantically equivalent to the original version. In the second step, we evaluated the psychometric properties of the French version, including the internal consistency and reliability, the differential item functioning, and the external validity. Participants older than 18, undergoing elective surgery (except obstetric), able to understand and read French, and able to complete a self-report questionnaire were eligible for inclusion in the study. A forward-backward translation was performed. The psychometric evaluation covered three domains: internal validity, external validity, and acceptability. Within 4-48 h after surgery, the patients were asked to complete the "Evaluation du Vécu de l'ANesthésie" questionnaire" (EVAN) questionnaire, which is a validated, multi-dimensional questionnaire that assesses the patient's experiences in the perioperative period. RESULTS A database with 175 patients was created. The principal component factor analysis revealed the same three-dimensional structure as the original scale. The confirmatory factor analysis showed a strong fit with a root mean square error of approximation of 0.069 and a comparative fit index of 1.00. The amount of differential item functioning (DIF) between the subgroups of patients (i.e., based on age, gender, type of anaesthesia or surgery, premedication, ASA physical status, and ambulatory course) was low. The APAIS was strongly correlated with the dimensions of the EVAN. Each dimension had a low proportion of missing values (ranging from 0.6 to 2.9%), which indicates good acceptability of the questionnaire. CONCLUSIONS The French version of the APAIS is valid and reliable. The availability of this tool enables the evaluation of anxiety in French patients undergoing anaesthesia.

Abstract
OBJECTIVE Many studies have demonstrated beneficial effects of either erythropoietin (EPO) or endothelial progenitor cell (EPC) treatment in cerebral ischemia. To improve post-ischemic tissue repair, we investigated the effect of systemic administration of endothelial colony-forming cells (ECFCs), considered as relevant endothelial progenitors due to their specific vasculogenic activity, in the presence or absence of EPO, on functional recovery, apoptosis, angiogenesis, and neurogenesis in a transient focal cerebral ischemia model in the adult rat. DESIGN Experimental study. INTERVENTION The rats were divided into four groups 24 hours after ischemia,, namely control, ECFCs, EPO, and ECFCs+EPO, and received a single intravenous injection of ECFCs (5 × 10(6) cells) and/or intraperitoneal administration of EPO (2500 UI/kg per day for 3 days). MEASUREMENT Infarct volume, functional recovery, apoptosis, angiogenesis, and neurogenesis were assessed at different time points after ischemia. MAIN RESULTS The combination of EPO and ECFCs was the only treatment that completely restored neurological function. The ECFCs+EPO treatment was also the most effective to decrease apoptosis and to increase angiogenesis and neurogenesis in the ischemic hemisphere compared to controls and to groups receiving ECFCs or EPO alone. CONCLUSION These results suggest that EPO could act in a synergistic way with ECFCs to potentiate their therapeutic benefits.

Abstract
INTRODUCTION Stroke is one of the leading causes of death and disability worldwide. Intravenous recombinant tissue plasminogen activator is the only available therapy for acute ischemic stroke, but its use is limited by a narrow therapeutic window and cannot stimulate endogenous repair and regeneration of damaged brain tissue. Stem cell-based approaches hold much promise as potential novel treatments to restore neurological function after stroke. STATE OF THE ART In this review, we summarize data from preclinical and clinical studies to investigate the potential application of stem cell therapies for treatment of stroke. Stem cells have been proposed as a potential source of new cells to replace those lost due to central nervous system injury, as well as a source of trophic molecules to minimize damage and promote recovery. Various stem cells from multiple sources can generate neural cells that survive and form synaptic connections after transplantation in the stroke-injured brain. Stem cells also exhibit neurorevitalizing properties that may ameliorate neurological deficits through stimulation of neurogenesis, angiogenesis and inhibition of inflammation. PERSPECTIVES/CONCLUSION Performed in stroke, cell therapy would decrease brain damage and reduce functional deficits. After the damage has been done, it would still improve neurological functions by activating endogenous repair. Nevertheless, many questions raised by experimental studies particularly related to long-term safety and technical details of cell preparation and administration must be resolved before wider clinical use.

The treatment of pulmonary embolism is mainly based on anticoagulants and intravenous thrombolysis in case of collapse. The cerebral hemorrhage is the main complication of thrombolysis and contraindicates anticoagulation. We report the case of a patient with a subdural and intraparenchymal hematoma complicating intravenous thrombolysis. The patient had persistent respiratory and hemodynamic instability related to the pursuit of embolic phenomena. The implementation of a cava filter was performed and the patient had a favorable outcome.

Abstract
The clinical importance of cardiovascular consequences resulting from cerebral injury has long been recognized. However, interactions between the brain and the cardiovascular system remain poorly defined and their importance for the management of patients suffering from acute brain injury is largely underestimated. This should have profound consequences on treatment strategies during anaesthesia and intensive cares of these patients, taking into account not only brain perfusion, but also cardiovascular optimisation. This report summarizes the main data available regarding the cardiovascular consequences of brain death, traumatic brain injury, stroke and epilepsy.

Abstract
Head injuries are present in up to 65 % of multiple trauma patients with a frequent association with orthopaedic injuries. The concept of early surgical stabilization of long-bone fractures in patients with multiple injuries became firmly established in the 1980s. However, optimal timing of long bone fracture fixation in trauma patients with associated severe traumatic brain injury has been a lively topic. The available literature does not provide clear-cut guidance on the management of fractures in the presence of head injuries. The trend is toward a better outcome if the fractures are fixed early. In recent years, some studies reported a worse outcome, with secondary brain damage, resulting from hypotension, hypoxia and increased intraoperative fluid administration. This review summarises the current evidence available regarding the management of these patients in particular the recent concept of early temporary surgical stabilization in the era of "damage control orthopaedic surgery".

Abstract
Over the past 15 years, a large body of evidence has revealed that the cytokine erythropoietin exhibits non-erythropoietic functions, especially tissue-protective effects. The discovery of EPO and its receptors in the central nervous system and the evidence that EPO is made locally in response to injury as a protective factor in the brain have raised the possibility that recombinant human EPO (rhEPO) could be administered as a cytoprotective agent after acute brain injuries. This review highlights the potential applications of rhEPO as a neuroprotectant in experimental and clinical settings such as ischemia, traumatic brain injury, and subarachnoid and intracerebral hemorrhage. In preclinical studies, EPO prevented apoptosis, inflammation, and oxidative stress induced by injury and exhibited strong neuroprotective and neurorestorative properties. EPO stimulates vascular repair by facilitating endothelial progenitor cell migration into the brain and neovascularisation, and it promotes neurogenesis. In humans, small clinical trials have shown promising results but large prospective randomized studies failed to demonstrate a benefit of EPO for brain protection and showed unwanted side effects, especially thrombotic complications. Recently, regions have been identified within the EPO molecule that mediate tissue protection, allowing the development of non-erythropoietic EPO variants for neuroprotection conceptually devoid of side effects. The efficacy and the safety profile of these new compounds are still to be demonstrated to obtain, in patients, the benefits observed in experimental studies.

Abstract
There is a large body of experimental evidence showing benefits of deliberate mild hypothermia (33-35 degrees C) on the injured brain as well as an improvement of neurological outcome after cardiac arrest in humans. However, the clinical evidence of any benefit of hypothermia following stroke, brain trauma and neonatal asphyxia is still lacking. Controversial results have been published in patients with brain trauma or neonatal asphyxia. Hypothermia can reduce the elevation of intracranial pressure, through mechanisms not completely understood. Hypothermia-induced hypocapnia should have a role on the reduction of intracranial pressure. The temperature target is unknown but no additional benefit was found below 34 degrees C. The duration of deliberate hypothermia for the treatment of elevated intracranial pressure might be at least 48 hours, and the subsequent rewarming period must be very slow to prevent adverse effects.

Abstract
SUMMARY SAH is still a severe pathology carrying a high risk of death or severe neurological morbidity. New diagnostic, monitoring and therapeutic methods are available for the detection and treatment of vasospasm. This includes transcranial Doppler, CT or MRI perfusion scan, protein S100B dosage, cerebral blood flow monitoring at the bedside. Medical treatment of vasospasm relies on increased blood pressure and dobutamine. Emergency balloon angioplasty or arterial vasodilator infusion is mandatory in case of vasospam- induced ischemic deficit. Despite several medical advances in the treatment of subarachnoid haemorrhage (SAH) due to aneurysm rupture, particularly interventional neuroradiology, it remains a potentially devastating illness with a high mortality rate. The most important determinant of outcome is neurologic state on arrival in the hospital, assessed with the World Federation of Neurological Surgeons (WFNS) scale (table 1) (1). Delayed cerebral ischemia due to cerebral vasospasm and medical complications due to SAH have both a major impact on outcome. The cooperative aneurysm study, including 457 patients with SAH, showed that the proportion of deaths from medical complications (23%) was comparable with the proportion of deaths attributed to the direct effects of the initial hemorrhage (19%), rebleeding (22%), and vasospasm (23%) after aneurysmal rupture (2). Thus, the aim of ICU management is to prevent or to limit the consequences of vasospasm and to treat medical complications that can have an adverse effect on the brain.
