Contralateral acute epidural haematoma following evacuation of a chronic subdural haematoma with burr hole craniostomy and continuous closed system drainage a rare complication

Clinical Neurology and Neurosurgery Volume 108, Issue 4 , June 2006, Pages 396-399

Chronic subdural haematoma (CSDH) is one of the most frequent causes for neurosurgical intervention. Although the prognosis is generally good and treatment modalities are well established, some devastating intracranial haematomas can complicate its evacuation. The authors report here a case of an acute epidural haematoma occurring after evacuation of a contralateral chronic subdural haematoma (CSDH) with burr-hole craniostomy and continuous closed system drainage without irrigation. Since this is a rare, but potentially life-threatening, complication, clinicians should suspect its occurrence when an unexpected postoperative course is demonstrated.

The Predictive Value of Field versus Arrival Glasgow Coma Scale Score and TRISS Calculations in Moderate to Severe Traumatic Brain Injury

Journal of Trauma-Injury Infection & Critical Care. 60(5):985-990, May 2006

Glasgow Coma Scale (GCS) scores are widely used to quantify level of consciousness in the prehospital environment. The predictive value of field versus arrival GCS is not well defined but has tremendous implications with regard to triage and therapeutic decisions as well as the use of various predictive scoring systems, such as Trauma Score and Injury Severity Score (TRISS). This study explores the predictive value of field GCS (fGCS) and arrival GCS (aGCS) as well as TRISS calculations using field (fTRISS) and arrival (aTRISS) data in patients with moderate-to-severe traumatic brain injury (TBI).

Lymphocytic Choriomeningitis Virus An Old Enemy up to New Tricks

New England Journal of Medicine Volume 354:2208-2211 May 25, 2006 Number 21

Lymphocytic choriomeningitis virus (LCMV) was among the first human pathogenic viruses to be isolated. In the mid-1930s, Armstrong and Lillie obtained a filterable agent thought to be from the brain of a man who died during an epidemic of St. Louis encephalitis, Traub discovered a chronic infection in a mouse colony, and Rivers and Scott isolated a virus from the cerebrospinal fluid of patients with aseptic meningitis.

Interneuron and Pyramidal Cell Interplay During In Vitro SeizureLike Events

J Neurophysiol 95: 3948-3954, 2006

Excitatory and inhibitory (EI) interactions shape network activity. However, little is known about the EI interactions in pathological conditions such as epilepsy. To investigate EI interactions during seizure-like events (SLEs), we performed simultaneous dual and triple whole cell and extracellular recordings in pyramidal cells and oriens interneurons in rat hippocampal CA1. We describe a novel pattern of interleaving EI activity during spontaneous in vitro SLEs generated by the potassium channel blocker 4-aminopyridine in the presence of decreased magnesium.

The Rete Mirabile of the Cranial Base A Millenary Legend

Neurosurgery. 58(6):1198-1208, June 2006

THE RETE MIRABILE, a vascular network assumed to give origin to the intracranial segments of the internal carotid arteries, was interpreted by Galen as the key station for the conversion of the "vital spirit" into the "animal spirit." According to this interpretation, the rete was determinant either in sustaining the cerebral functions, or in controlling the reproductive process in humans.

Systemic Administration of Simvastatin after the Onset of Experimental Subarachnoid Hemorrhage Attenuates Cerebral Vasospasm

Neurosurgery. 58(5):945-951, May 2006

Experimental evidence suggests that intercellular adhesion molecule-1 mediated leukocyte extravasation contributes to the pathogenesis of cerebral vasospasm. Simvastatin, an HMG-CoA reductase inhibitor, decreases intercellular adhesion molecule-1 expression and competitively inhibits leukocyte intercellular adhesion molecule-1 binding. We hypothesized that administration of simvastatin after the onset of subarachnoid hemorrhage (SAH) would attenuate perivascular granulocyte migration and ameliorate cerebral vasospasm in a rabbit model of SAH.

Permanent dysphasia after status epilepticus Long term follow-up in an elderly patient

Epilepsy & Behavior Volume 8, Issue 3 , May 2006, Pages 677-680

We report the long-term follow-up of an elderly patient who developed a permanent sensorimotor dysphasia after status epilepticus. Magnetic resonance imaging of the brain and magnetic resonance angiography failed to demonstrate structural cerebral damage; however, a fluorodeoxyglucose positron emission tomography scan revealed marked hypometabolism involving a large area in the left hemisphere and contralateral cerebellar cortex. Our case illustrates that permanent language dysfunction may occur after recurrent complex partial and secondarily generalized seizures.

In vitro responsiveness of human drug resistant tissue to antiepileptic drugs Insights into the mechanisms of pharmacoresistance

Brain Research Volume 1086, Issue 1 , 1 May 2006, Pages 201-213

Pharmacoresistance in epileptic patients may be ascribed to at least two, not mutually exclusive, mechanisms: a pharmacokinetic mechanism and a decreased sensitivity or availability of targets to antiepileptic drugs (AEDs; i.e., carbamazepine and phenytoin (CBZ, PHT)). Brain:plasma drug concentration ratios were determined intraoperatively during lobectomies performed to alleviate drug-resistant seizures.

Cognitive performance of patients with mesial temporal lobe epilepsy is not associated with human prion protein gene variant allele at codons 129 and 171

Epilepsy & Behavior Volume 8, Issue 3 , May 2006, Pages 635-642

Cognitive impairment has long been recognized in people with medically refractory epilepsies. Mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE-HS), the most common surgically remediable epileptic syndrome, has been associated with a cellular prion protein (PrPc) gene (Prnp) variant allele at codon 171. The polymorphism consisting of a methionine-for-valine substitution at codon 129 has been associated with early cognitive deterioration in elderly people and patients with Down syndrome.

Role of interictal epileptiform abnormalities in cognitive impairment

Epilepsy & Behavior Volume 8, Issue 3 , May 2006, Pages 504-515

The epileptic encephalopathies are conditions in which neurological deterioration is attributable entirely or partly to epileptic activity and is due to very frequent or severe seizures or severely abnormal electroencephalograms (EEGs), or both. Evidence for the concept that seizures or the abnormal EEGs are responsible for the cognitive deterioration is the observation that patients can improve dramatically when therapy eliminates or reduces seizure frequency and improves or normalizes the EEG. For example, children with the syndrome of continuous spike–wave of sleep (CSWS) have electrical status epilepticus during sleep (ESES) and cognitive regression.

Rapid versus slow withdrawal of antiepileptic drugs

The Cochrane Library, Issue 2, 2006

The ideal objective of treating a person with epilepsy is to induce remission by usage of antiepileptic drugs (AEDs) and withdraw the AEDs without causing seizure recurrence. Prolonged usage of AEDs may have long-term side effects. Hence when a person with epilepsy is in remission (free of seizures for some time) it is logical to attempt to discontinue the medication. The timing of withdrawal and the mode of withdrawal arise while contemplating withdrawal of AEDs. This review proposes to examine the evidence for the rate of withdrawal of AEDs (whether rapid or slow tapering) and its effect on recurrence of seizure.

Transdermal Glyceryl Trinitrate Lowers Blood Pressure and Maintains Cerebral Blood Flow in Recent Stroke

Hypertension. 2006;47:1209

High blood pressure (BP) is common in acute stroke and is independently associated with a poor outcome. Lowering BP might improve outcome if it did not adversely affect cerebral blood flow (CBF) or cerebral perfusion pressure. We investigated the effect of glyceryl trinitrate ([GTN] an NO donor) on quantitative CBF, BP, and cerebral perfusion pressure in patients with recent stroke.

Differentiating the Roles of the Hippocampus and Perirhinal Cortex in Processes beyond Long Term Declarative Memory A Double Dissociation in Dementia

The Journal of Neuroscience, May 10, 2006, 26(19):5198-5203; doi:10.1523/JNEUROSCI.3157-05.2006

There is increasing evidence to suggest that the hippocampus and perirhinal cortex may mediate processes beyond long-term declarative memory. We assessed patients with Alzheimer's disease (AD) or semantic dementia (SD) on a visual oddity judgment task that did not place an explicit demand on long-term memory and is known to be sensitive to hippocampal and perirhinal cortex lesions.

Systems Consolidation Requires Postlearning Activation of NMDA Receptors in the Medial Prefrontal Cortex in Trace Eyeblink Conditioning

The Journal of Neuroscience, May 10, 2006, 26(19):5049-5058; doi:10.1523/JNEUROSCI.4381-05.2006

The importance of the hippocampus in declarative memory is limited to recently acquired memory, and remotely acquired memory is believed to be stored somewhere in the neocortex. However, it remains unknown how the memory network is reorganized from a hippocampus-dependent form into a neocortex-dependent one. We reported previously that the medial prefrontal cortex (mPFC) is important for this neocortex-dependent remote memory in rat trace eyeblink conditioning.

Hemodynamics in a Cerebral Artery before and after the Formation of an Aneurysm

American Journal of Neuroradiology 27:1113-1118, May 2006

Using data obtained from 3D digital subtraction angiography acquisitions, computational fluid dynamics techniques were used first to assess hemodynamic factors in geometrically correct models of 3 paraclinoid aneurysms and then again for assessment after virtual removal of the aneurysms and reconstruction of the parent artery. Simulations revealed an area of relatively low and rotating wall shear stresses at the location at which each aneurysm had developed. This phenomenon, to our knowledge, has not been previously described.

Visualization of Hemodynamics in a Silicon Aneurysm Model Using Time Resolved 3D Phase Contrast MRI

American Journal of Neuroradiology 27:1119-1122, May 2006

We performed time-resolved 3D phase-contrast MR imaging by using a 1.5T MR scanner to visualize hemodynamics in a silicon vascular model with a middle cerebral aneurysm. We ran an aqueous solution of glycerol as a flowing fluid with a pulsatile pump. Time-resolved images of 3D streamlines and 2D velocity vector fields clearly demonstrated that the aneurysm had 3D complex vortex flows within it during systolic phase. This technique provided us with time-resolved 3D hemodynamic information about the intracranial aneurysm.

The Radial Artery Access Site for Interventional Neuroradiology Procedures

The radial artery access site offers many advantages in neuroangiography. Right vertebral artery access is readily obtained from a right radial artery approach. As with cardiology procedures, neuroradiology procedures may necessitate the use of lytic therapy or platelet inhibitors. Sheath removal can be done without reversal of anticoagulation or concerns about major bleeding complications. We report our experience in using the radial artery access site for interventional neuroradiology cases. Practical considerations and technical details are offered.

Head computed tomography guidelines are being followed

Emergency Medicine Australasia, Volume 18, Number 3, June 2006, pp. 238-244(7)

Several guidelines have been developed to direct the ordering of head computed tomography (CT) for patients, but most are clinical presentation-specific. Recently, an integrated guideline for ordering emergent head CT for patients who present to the ED of Western Hospital, Footscray, Victoria, Australia, was developed in response to concerns raised regarding perceived over-utilization of head CT for ED patients. Our aim was to determine compliance with the guideline.

Paramedic intubation of patients with severe head injury a review of current Australian practice and recommendations for change

Emergency Medicine Australasia, Volume 18, Number 3, June 2006, pp. 221-228(8)

Secondary brain injury may occur early after severe traumatic brain injury due to hypoxia and/or hypotension. Prehospital care by ambulance paramedics has the goal of preventing and treating these complications and, thus, improving outcomes. In Australia, most ambulance services recommend paramedics attempt endotracheal intubation in patients with severe head injury. Even though most patients with severe head injury retain airway reflexes, most states do not allow the use of appropriate drugs to facilitate intubation. In contrast, recent evidence from trauma registries suggests that this approach may be associated with significantly worse outcomes compared with no intubation.

Fatigue in Neurological Psychiatric and Medical Conditions

Journal of the International Neuropsychological Society (2006), 12: 442-444

Fatigue is ubiquitous and falls within the purview of several specialties, including neurology, psychiatry, neuropsychology, endocrinology, rheumatology, and immunology. As Simon Wessely points out in the Foreword of Fatigue as a Window to the Brain, fatigue has been virtually overlooked as an area of scientific study, because it is difficult to measure and, as a symptom, rarely aids in differential diagnosis.

Demographic and cognitive predictors of long term psychosocial outcome following traumatic brain injury

Journal of the International Neuropsychological Society (2006), 12: 350-358

Demographic factors and cognitive impairment have been found previously to have associations with outcome after brain injury. Kendall and Terry (1996) suggest that preinjury psychosocial functioning, neurological factors, and cognitive impairment have a direct relationship with multidimensional psychosocial adjustment, but that cognitive impairment also has an indirect relationship by means of the mediation of appraisal and coping variables. The aim of this study was to explore these theoretical relationships at very late stages of recovery after brain injury.

Cognitive dysfunction in epilepsy Case reports

Seizure Volume 15, Issue 4 , June 2006, Pages 264-266

Cognitive dysfunction in people with epilepsy is a frequently encountered but also easily overlooked problem. In this article three patients with epilepsy are presented with cognitive problems due to a relapse of seizures, due to continuing absence seizures or as a consequence of deteriorating mental functions resulting from frequent complex partial seizures. In the last patient the decline in mental functioning was also demonstrated in a disseminated activation pattern on her fMRI, which contrasts with the localised activity as seen in controls on fMRI. Suggestions how to handle these problems in daily practice are given.

Neonatal factors influence adult stroke outcome

Psychoneuroendocrinology Volume 31, Issue 5 , June 2006, Pages 601-613

Neonatal environment can have important, life-long influences on stress-reactivity and hypothalamic–pituitary–adrenal (HPA) axis regulation. In rodents, brief mother–infant separations have been shown to improve efficiency of the HPA axis, decrease stress-reactivity, and decrease age-related declines in cognitive function. Here, we provide evidence that there are potential costs associated with improved HPA axis regulation, including increased sensitivity to cerebral inflammation and glucocorticoid-mediated neuronal death following stroke.

Cognitive side effects of anti epileptic drugs The relevance in childhood epilepsy

Seizure Volume 15, Issue 4 , June 2006, Pages 235-241

In recent years several new anti-epileptic drugs have been introduced, also for the treatment of childhood epilepsy. A major concern is their effect on learning and cognitive development. Testing the genuine effects on cognition of the anti-epileptic drugs is methodologically not easy. At this moment there are very few controlled trials that systematically examine the cognitive side effects of anti-epileptic drugs in childhood epilepsy. The available data indicate that the newer anti-epileptic drugs have a safe cognitive profile when prescribed correctly at the right dose and in monotherapy. Possible negative effects are mainly found for speed of processing and attention processes. As these processes are important instruments in every day learning and cognition, it is necessary to test these newer anti-epileptic drugs in well designed studies and in specific childhood epilepsy syndromes.

Intraoperative Magnetic Resonance Imaging guided neurosurgery at 3 T

Neurosurgery. 58(4) Operative Neurosurgery Supplement 2:ONS-338-ONS-346, April 2006

Between 1997 and 2004, more than 700 neurosurgical procedures were performed in a 1.5-T magnetic resonance-guided therapy suite. During this period, the concept of high-field intraoperative magnetic resonance imaging (MRI) was validated, as was a new surgical guidance tool, the Navigus (Image-guided Neurologics, Melbourne, FL), and its methodology, prospective stereotaxy. Clinical protocols were refined to optimize surgical techniques. That implementation, the "Minnesota suite," has recently been revised, and a new suite with a 3-T MRI scanner has been developed.

Double dissociation between representational personal and extrapersonal neglect

NEUROLOGY 2006;66:1414-1417

Although perceptual and representational neglect are frequently associated, the demonstration of a double dissociation between both neglect forms suggests that both rely on different central mechanisms. In addition, perceptual neglect can be selectively observed within personal space or extrapersonal space. However, it is not known whether the latter dissociation also exists in representational neglect.

Twin Peaks An ERP Study of Action Planning and Control in Coacting Individuals

Journal of Cognitive Neuroscience. 2006;18:859-870

Previous studies have shown that perceiving another's actions activates corresponding representations in an observer's action system. The present study investigated how performing a task with another person affects action planning and control. Reaction times (RTs) and event-related potentials were measured while participants performed a go/no-go task alone and with another person. Three effects of acting together were observed. First, RTs were slowed when individuals had to respond to a stimulus referring to the other's action, suggesting that an action selection conflict occurred. Second, at frontal sites, a stimulus referring to the other's action elicited a similar electrophysiological response as a stimulus referring to one's own action. Finally, on no-go trials, P300 amplitude was significantly larger in a group setting, indicating that an action was suppressed. These findings provide evidence that individuals acting in a social context form shared action representations.

The potential of pharmacogenetics in the treatment of epilepsy

European Journal of Paediatric Neurology Volume 10, Issue 2 , March 2006, Pages 57-65

Pharmacogenetics studies how genetic variants influence individual drug responses. Although pharmacogenetics is currently the subject of intensive research in several disease domains, it remains relatively unexplored in the field of epilepsy. Drug treatment of epilepsy is characterized by unpredictability of efficacy, adverse drug reactions and optimal doses in individual patients. Moreover, a substantial fraction of patients develop drug refractory epilepsy despite optimal treatment.

Cognitive effects of seizures

Seizure Volume 15, Issue 4 , June 2006, Pages 221-226

We aimed to review recent prospective and cross-sectional studies regarding the gradual and chronic effects of (cumulative) seizures on cognition. In contrast with the increasing evidence of structural changes in the brain associated with repeated seizures, its functional repercussions remain unclear. Methodological difficulties of cross-sectional and prospective studies are addressed. It appears that all but one of the prospective studies available on children are limited to measures of intelligence. Most studies revealed no significant adverse effects, although there appears to be a subgroup of about 10–25% of children that shows a clinically significant intellectual decline. Children with generalized symptomatic epilepsies, frequent seizures, high antiepileptic drug use, and early onset of epilepsy appear at risk, although psychosocial factors may also play an important role.
