[PMID: 28506487 DOI: 10.1016/j.neuchi.2017.01.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Revised: 01/23/2017] [Accepted: 01/27/2017] [Indexed: 11/17/2022]
Abstract
Monopolar mapping of motor function differs from the most commonly used method of intraoperative mapping, i.e. bipolar direct electrical stimulation at 50-60Hz (Penfield technique mapping). Most importantly, the monopolar probe emits a radial, homogenous electrical field different to the more focused inter-tip bipolar electrical field. Most users combine monopolar stimulation with the short train technique, also called high frequency stimulation, or train-of-five techniques. It consists of trains of four to nine monopolar rectangular electrical pulses of 200-500μs pulse length with an inter stimulus interval of 2-4msec. High frequency short train stimulation triggers a time-locked motor-evoked potential response, which has a defined latency and an easily quantifiable amplitude. In this way, motor thresholds might be used to evaluate a current-to-distance relation. The homogeneous electrical field and the current-to-distance approximation provide the surgeon with an estimate of the remaining distance to the corticospinal tract, enabling the surgeon to adjust the speed of resection as the corticospinal tract is approached. Furthermore, this stimulation paradigm is associated with a lower incidence of intraoperative seizures, allowing continuous stimulation. Hence, monopolar mapping is increasingly used as part of a strategy of continuous dynamic mapping: ergonomically integrated into the surgeon's tools, the monopolar probe reliably provides continuous/uninterrupted feedback on motor function. As part of this strategy, motor mapping is not any longer a time consuming interruption of resection but rather a radar-like, real-time information system on the spatial relationship of the current resection site to eloquent motor structures.

Abstract
A subcutaneous mass of the skull in children can have many different causes (infectious, tumoral, and inflammatory). We report on the case of a 5-year-old patient with a subcutaneous mass of the skull evolving over several months. The first pathological analysis concluded in Kimura disease. The progression and scarcity of this entity in children led to a second pathological analysis that showed lymphoblastic lymphoma B (LLB). This case reminds us that when there are discrepancies between pathological conclusions and clinical progression of a tumoral process, repeated analysis and immunochemistry are necessary.

Abstract
The metabotropic glutamate receptor 2 (mGlu2) plays an important role in the presynaptic control of glutamate release and several mGlu2 positive allosteric modulators (PAMs) have been under assessment for their potential as antipsychotics. The binding mode of mGlu2 PAMs is better characterized in functional terms while few data are available on the relationship between allosteric and orthosteric binding sites. Pharmacological studies characterizing binding and effects of two different chemical series of mGlu2 PAMs are therefore carried out here using the radiolabeled mGlu2 agonist 3[H]-LY354740 and mGlu2 PAM 3[H]-2,2,2-TEMPS. A multidimensional approach to the PAM mechanism of action shows that mGlu2 PAMs increase the affinity of 3[H]-LY354740 for the orthosteric site of mGlu2 as well as the number of 3[H]-LY354740 binding sites. 3[H]-2,2,2-TEMPS binding is also enhanced by the presence of LY354740. New residues in the allosteric rat mGlu2 binding pocket are identified to be crucial for the PAMs ligand binding, among these Tyr3.40 and Asn5.46. Also of remark, in the described experimental conditions S731A (Ser5.42) residue is important only for the mGlu2 PAM LY487379 and not for the compound PAM-1: an example of the structural differences among these mGlu2 PAMs. This study provides a summary of the information generated in the past decade on mGlu2 PAMs adding a detailed molecular investigation of PAM binding mode. Differences among mGlu2 PAM compounds are discussed as well as the mGlu2 regions interacting with mGlu2 PAM and NAM agents and residues driving mGlu2 PAM selectivity. This article is part of the Special Issue entitled 'Metabotropic Glutamate Receptors, 5 years on'.

Abstract
BACKGROUND AND PURPOSE For patients with cerebral vasospasm refractory to medical and hemodynamic therapies, endovascular therapies often remain the last resort. Data from studies in large cohorts on the efficacy and safety of multiple immediate endovascular interventions are sparse. Our aim was to assess the feasibility and safety of multiple repeat instant endovascular interventions in patients with cerebral vasospasm refractory to medical, hemodynamic, and initial endovascular interventions. MATERIALS AND METHODS This was a single-center retrospective study of prospectively collected data on patients with cerebral vasospasm refractory to therapies requiring ≥3 endovascular interventions during the course of treatment following aneurysmal subarachnoid hemorrhage. The primary end point was functional outcome at last follow-up (mRS ≤2). The secondary end point was angiographic response to endovascular therapies and the appearance of cerebral infarctions. RESULTS During a 4-year period, 365 patients with aneurysmal subarachnoid hemorrhage were treated at our institution. Thirty-one (8.5%) met the inclusion criteria. In 52 (14%) patients, ≤2 endovascular interventions were performed as rescue therapy for refractory cerebral vasospasm. At last follow-up, a good outcome was noted in 18 (58%) patients with ≥3 interventions compared with 31 (61%) of those with ≤2 interventions (P = .82). The initial Hunt and Hess score of ≤2 was a significant independent predictor of good outcome (OR, 4.7; 95% CI, 1.2-18.5; P = .03), whereas infarcts in eloquent brain areas were significantly associated with a poor outcome (mRS 3-6; OR, 13.5; 95% CI, 2.3-81.2; P = .004). CONCLUSIONS Repeat instant endovascular intervention is an aggressive but feasible last resort treatment strategy with a favorable outcome in two-thirds of patients with refractory cerebral vasospasm and in whom endovascular treatment has already been initiated.

Abstract
BACKGROUND The causes of phenotypic heterogeneity in familial Alzheimer's disease with autosomal dominant inheritance are not well understood. We aimed to characterise clinical phenotypes and genetic associations with APP and PSEN1 mutations in symptomatic autosomal dominant familial Alzheimer's disease (ADAD). METHODS We retrospectively analysed genotypic and phenotypic data (age at symptom onset, initial cognitive or behavioural symptoms, and presence of myoclonus, seizures, pyramidal signs, extrapyramidal signs, and cerebellar signs) from all individuals with ADAD due to APP or PSEN1 mutations seen at the Dementia Research Centre in London, UK. We examined the frequency of presenting symptoms and additional neurological features, investigated associations with age at symptom onset, APOE genotype, and mutation position, and explored phenotypic differences between APP and PSEN1 mutation carriers. The proportion of individuals presenting with various symptoms was analysed with descriptive statistics, stratified by mutation type. FINDINGS Between July 1, 1987, and Oct 31, 2015, age at onset was recorded for 213 patients (168 with PSEN1 mutations and 45 with APP mutations), with detailed history and neurological examination findings available for 121 (85 with PSEN1 mutations and 36 with APP mutations). We identified 38 different PSEN1 mutations (four novel) and six APP mutations (one novel). Age at onset differed by mutation, with a younger onset for individuals with PSEN1 mutations than for those with APP mutations (mean age 43·6 years [SD 7·2] vs 50·4 years [SD 5·2], respectively, p<0·0001); within the PSEN1 group, 72% of age at onset variance was explained by the specific mutation. A cluster of five mutations with particularly early onset (mean age at onset <40 years) involving PSEN1's first hydrophilic loop suggests critical functional importance of this region. 71 (84%) individuals with PSEN1 mutations and 35 (97%) with APP mutations presented with amnestic symptoms, making atypical cognitive presentations significantly more common in PSEN1 mutation carriers (n=14; p=0·037). Myoclonus and seizures were the most common additional neurological features; individuals with myoclonus (40 [47%] with PSEN1 mutations and 12 [33%] with APP mutations) were significantly more likely to develop seizures (p=0·001 for PSEN1; p=0·036 for APP), which affected around a quarter of the patients in each group (20 [24%] and nine [25%], respectively). A number of patients with PSEN1 mutations had pyramidal (21 [25%]), extrapyramidal (12 [14%]), or cerebellar (three [4%]) signs. INTERPRETATION ADAD phenotypes are heterogeneous, with both age at onset and clinical features being influenced by mutation position as well as causative gene. This highlights the importance of considering genetic testing in young patients with dementia and additional neurological features in order to appropriately diagnose and treat their symptoms, and of examining different mutation types separately in future research.

Abstract
A new venous bag has been developed, prototyped, and tested. The new bag has its inlet, outlet purge, and infusion tubes extending upward from the top of the bag, and are threaded through, bonded to, and sealed within a flat rigid top plate. This design allows the bag to be hung from its top plate by its tubes. It also allows the bag to be: 1) dropped into or removed from its holder, as is done with existing hard-shell reservoirs so that its weight pulls it into the holder without the need for eyelets and hooks and 2) placed closer to the floor so that gravity drainage is facilitated. The V-Bag® (VB) is easily sealed within an accompanying rigid housing. Once sealed, vacuum applied to the housing is transmitted across the flexible walls of the bag to the venous blood. Thus, vacuum-assisted venous drainage (VAVD) is obtained as it is with a hard-shell reservoir, but without any contact of air with the blood. Bench tests, using a circuit that simulated the venous side of the cardiopulmonary bypass (CPB) circuit, showed that applying suction to the housing increased venous flow, and the fractional increase in flow was not a function of the venous cannula, but of the level of vacuum applied. In the gravity drainage mode, the bubble counts at the outlet of the V-Bag compared to two other bags were lower at any pumping condition. When used in the VAVD mode, bubble counts were two orders of magnitude lower than when using kinetically assisted venous drainage (KAVD) with a centrifugal pump. Results obtained with the VB suggest its clinical usefulness.

Abstract
BACKGROUND In solid organ transplantation, sensitive real-time biomarkers to assess the graft health are desirable to enable early intervention, for example, to avoid full-blown rejections. During rejection, high amounts of graft-derived cell-free DNA (GcfDNA) are shed into the blood stream. The quantification of this GcfDNA in allotransplantation is considered to fulfill this need, because it can be measured with great precision and at reasonable cost. PATIENTS AND METHODS Patients from 2 ongoing studies in kidney (KTx) and heart (HTx) transplantation were monitored blinded on a scheduled basis, by means of a published universal droplet digital polymerase chain reaction to quantify the GcfDNA. RESULTS Immediately after engraftment, GcfDNA reaches high values (>5% of total cfDNA), with a rapid decrease to values of <0.5% within 1 week. Living-related KTx recipients show lower initial values, reflecting the absence of preservation injury. Episodes of rejection in KTx and HTx are accompanied by a significant increase of GcfDNA (>5-fold) above values in patients without complications, occurring earlier than clinical or biochemical hints to rejection. One case of rejection, which became clinically suspect after 1 year and was proven with biopsy, showed a significant 10-fold increase 3 months earlier. CONCLUSIONS The quantification of GcfDNA has the potential to detect rejection episodes at early stages, when other means of diagnosis are not effective. The method's noninvasiveness enables the monitoring recipients at intervals that are desired to catch rejections at early actionable stages to prevent full-blown rejection. This biomarker will be particularly valuable in regimens to minimize immunosuppression.

Abstract
UNLABELLED In patients with metastasized, castration resistant prostate cancer (mCRPC) treatment with radium-223 (Xofigo) is an attractive therapeutic option. In particular, patients with high tumour load seem to profit from this treatment in regard of survival and quality of live. Aim of this study was to stratify mCRPC patients according to a quantitative imaging marker derived from routine bone scans (EXINI bone) and analyze haematopoietic toxicity of Xofigo in these patients. PATIENTS, METHODS Toxicity and oncologic outcome were investigated in a cohort of 14 patients with high tumour load. Additionally, based on a web survey, experience of toxicity in 41 high tumour load patients in Germany in 2014 was collected. RESULTS In patients with a bone scan index (BSI) greater than 5, significant toxicity occurred in more patients than expected from the ALSYMPCA trial. This was associated with application of fewer cycles. Similar experiences have been made in other centers in Germany. Approximately 7% of these patients will need very long time or will not recover from grade ≥ 3 toxicity. CONCLUSION Close follow-up of haematopoietic indices and, in case of toxicity, early termination of therapy is in particular necessary in late stage disease where limited bone marrow reserve is likely.

Abstract
BackgroundSerum BDNF levels are decreased in major depressive disorder (MDD) and tend to normalize under antidepressant treatment, serving as a treatment outcome predictor. BDNF is initially synthetized as precursor protein proBDNF and is cleaved to mature BDNF (mBDNF) while only the latter exerts neurotrophic activity.AimThe aim was to explore if a specific enzyme-linked immunosorbent assay (ELISA) kit for mBDNF in serum would be superior to the unspecific assessment of total serum BDNF in predicting treatment response in MDD.MethodsTwenty-five patients with MDD underwent standardized treatment with duloxetine. Severity of depression was measured by Hamilton Depression Rating Scale (HDRS) at baseline (BL), after one (W1), two (W2) and six weeks (W6) of treatment. Treatment response was defined as a HDRS ≥ 50% reduction of BL score at W6. mBDNF and total BDNF serum levels were determined at BL, W1 and W2.ResultsA high and stable correlation was found between mBDNF and total BDNF serum levels over all measurements. The predictive value of mBDNF BL levels and mBDNFΔW1 to response was similar to that of total BDNF BL and total BDNFΔW1. The assessment of serum mBDNF was not superior to total BDNF in prediction of treatment outcome.ConclusionsNot only baseline total BDNF but also mBDNF is predictive to treatment outcome. The later might represent the main player in this respect, which supports the idea of a functional link between neuroplasticity and MDD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
A case report of a 68-year-old male obese diabetic patient with an abscess of left femoral region, and diffuse inflammation of abdominal wall and genital region developing sepsis, respiratory and renal failure. At admission in the regional hospital a diagnosis of polymicrobial necrotising fasciitis with suspected sepsis was declared. The patient was transferred to the special intensive care unit (SICU) of Burns and reconstructive surgery at the Kosice-Saca. The patient was treated surgically, with hyperbaric oxygen and pharmacologically to control his diabetes. The main aetiological agent of the condition was identified as Stenotrophomonas maltophilia. In addition to respiratory and metabolic acidosis and gastric bleeding occurred. Due to acute renal failure (day 38) the patient was transferred to clinic of anaesthesiology and the intensive care medicine at the University Hospital in Kosice. The patient was treated by continuous veno-venous haemodialysis, mechanical ventilation and nasogastric nutritional support. On day 48 the conscious sub-febrile patient with healed wounds was transferred back to the regional hospital with ventilation support and continuous renal replacement therapy. His diabetes was uncontrolled, and only kidney parameters remained pathological. The survival of this patient with an extremely poor prognosis was achieved through prompt transfer to a specialised centre, early identification of the aetiological agent and immediate appropriate antibiotic treatment as a result of good cooperation between surgeons and laboratory specialists.
