Abstract
Abstract
Background
Epithelioid glioblastoma is a rare subtype of Glioblastoma. We examine two cases who presented acutely with symptoms of headache, neck stiffness and an eye squint. The purpose of this case review is to look at their management, the spread of the disease and propose the availability of BRAF inhibiting agents be made readily available for this subtype.
Material and Methods
The clinical records including pathology and surgical reports, multi-disciplinary team meeting documents, oncology plans and inpatient notes have all been reviewed alongside the literature on epithelioid GBM and BRAF V600e mutations and inhibitors.
Results
Patients were females aged 25 and 32 presenting with acute onset headache and neck stiffness to emergency Department. The 25 year old had developed a right eye squint within seven days of the other symptoms, her tumour was right frontal with midline shift. The 32 year old had symptoms for 10 days prior to presentation, the tumour was right temporal. They both underwent craniotomies. The frontal tumour was totally resected, while the temporal lobe tumour was haemorrhagic in nature and minimally de-bulked. Pre-operative stealth imaging showed that there had been an increase in the size of the temporal lesion in the fourteen days since presentation. Histology proved these to be epithelioid GBM’s with BRAF V600e mutations, IDH wild-type and TERT promoter mutant. Full pathology reports with molecular markers were available within ten days. The frontal lobe patient began chemo-radiation sixteen days from her surgical date. On day two she was admitted with severe headache and nausea. She became agitated, confused, and transferred back to the neurosurgery unit for management of hydrocephalus. She was diagnosed with PRES and simultaneously treated for this and hydrocephalus. Clinically she suffered storming, passing away exactly eight weeks from presentation. Seven days after surgery the temporal lobe tumour patient suffered a seizure and admitted for symptom management and expedite oncology treatment. She passed away six days later suffering continual neurological deterioration and the tumour progression with leptomeningeal spread. This was exactly four weeks from initial presentation.
Conclusion
The prognosis for epithelioid Glioblastoma is limited to weeks to short months. Extent of resection in these case studies demonstrates benefit in delaying progression though it is clear that time is of the essence from presentation, to surgery, to adjuvant treatment. Neither of these tumours were methylated meaning the standard treatment for glioblastoma is likely to lack efficacy. BRAF inhibitors should be made readily available for this rare sub-type to commence treatment expediently. Both patients suffered distressing neurological symptoms in their final days which require expert management and are best managed in a neurosurgical centre.

Abstract
Abstract
Background
As part of enhanced recovery after surgery in neuro oncology, carbohydrate loading drinks were reviewed to see if there were any benefits in administering this pre operatively, in particularly for patients for awake craniotomy electively. This method is currently used in colorectal and spinal teams within the trust. Carbohydrate loading drinks are clear, and can be consumed up to 2 hours before induction of anaesthesia. Currently reviewed for patients for awake craniotomy with the vision to implement for all patients planned for craniotomy, both asleep and awake. The concept of this drink, is that it helps with post-operative nausea and vomiting , insulin resistance, helps with energy boost which is helpful during awake craniotomies and potentially during their engagement with therapists post operatively and wound healing (Hausel J et al, 2005). This could essentially lead to safer discharge, reduced risk of wound infection and reduced length of stay.
Material and Methods
In a single centre, data for patients who have undergone awake craniotomies this year were abstracted. Patients planned for an awake surgery were prescribed carb-loading drinks. Due to the start date of this study, there were already a number of patients who have had their awake craniotomies without having carb-loading drinks prescribed. The data for both cohorts enabled comparison on engagement during and after awake craniotomies with therapists and length of stay.
Results
The current data collected has found that the average length of stay in the group who were not prescribed carbohydrate loading drinks pre operatively, had an average length of stay 7.2 days in total, 50% had experienced nausea and vomiting post operatively, which led therapists unable to perform assessments. 66% of patients in this group were found to have some form of difficulties engaging with the therapists during the awake phase of their craniotomies. Compared with patients who were prescribed the carbohydrate loading drink, the average length of stay was 4.6 days, with no post operative nausea and vomiting, no difficulties engaging with therapists post operatively.
Conclusion
Though the current data is of a small volume, carbohydrate loading pre-operatively can help patients for elective awake craniotomies and reduce length of stay in hospital, optimising their recovery in a fast yet safe manner to ensure they are in the best performance status prior to commencing oncology treatment. With further analysis into the use of carb-loading drinks pre-operatively, this can be used widely within neuro-oncology surgeries.

Abstract
BACKGROUND The use of intraoperative monitoring (IOM) in glioma surgery is a widely adopted and clinically validated adjunct to define safe zones of resection for the neurosurgeon. However, the role of IOM in cases of a significant preexisting motor deficit is questionable. CASE DESCRIPTION We describe a case of a 25-year-old with a recurrent presentation of a left paracentral glioblastoma, admitted with intratumoral hemorrhage and subsequent acute severe right-sided weakness. The patient underwent a redo left parietal craniotomy and 5-aminolevulinic acid-guided resection with IOM. The severity of the weakness was not reflected by the pre- and intraoperative cortical motor evoked potentials (MEPs) that were reassuring. The patient's hemiparesis recovered to full power postoperatively. CONCLUSIONS Preoperative weakness is traditionally accepted as a relative contraindication to IOM and therefore its usefulness is questioned in this context. Our case challenges this assumption. We present the clinical course, review the cranial and spinal literature including the reliability of IOM in cases of preoperative motor deficit, and discuss the need for tailor-made IOM strategies.

Abstract
Abstract
BACKGROUND
Invading glioma cells affect the physiological function of the peritumoural cortex. This may manifest clinically as seizures. Here, we investigate the effect the invading glioma cells on the electrophysiological signalling of the peritumoral cortex using living human brain tissue donated by people having a craniotomy for glioma resection (REC approval, 18/SW/002).
MATERIAL AND METHODS
The brain tissue was cut into thin slices, which preserved the architecture of the glioma and the adjacent healthy brain. The brain slices were incubated in 5-aminolevulinic acid to make the glioma cells fluorescent. We observed 5-ALA induced fluorescence in both low-grade and high-grade gliomas. This enabled us to make electrophysiological recordings of brain activity across the boundary between glioma and brain.
RESULTS
We recorded from brain slices of 5 participants with glioblastoma and 4 participants with oligodendroglioma (WHO grade II - III). Spontaneous “seizure-like” discharges were recorded in brain slices from 5/8 participants (3 GBM, 2 oligodendroglioma) who reported seizures and from one participant (GBM) who had not had any clinical seizures. Further analysis of the electrical discharges revealed that they could be subdivided into two distinct types based on the major frequencies in the discharge.
CONCLUSION
We concluded that human brain slices from people with either a low-grade or a high-grade glioma can generate spontaneous seizure-like discharges. This electrophysiological signature will be compared to infiltration and grade of the glioma cells in the donated sample. The living human brain tissue preparation gives us a platform to study the mechanisms of tumour-associated seizures and how abnormal neural activity affects glioma growth.

Abstract
ObjectivesThe first documented use of 5-ALA in the excision of an intraparenchymal endodermal cyst.DesignCase review.Subjects52 year old female presented with headaches, progressive right sided hemiparesis and anomic aphasia. She had a large cystic frontal lesion, adjacent of the frontal horn of the lateral ventricles cyst which did not show any nodular or solid component, and did not enhance with gadolinium.MethodsCase report and review of the literature.Results5-ALA assisted, image guided fenestration of the cystic lesion and insertion of a ventricular catheter connected to an Ommaya reservoir was performed. The cyst wall was observed under the microscope and it fluoresced with 5-ALA. Multiple biopsies were obtained from this tissue, which confirmed diagnosis of endodermal cyst. The patient had improvement in clinical symptoms and size of the cyst radiologically in both the immediate post-operative period and the 6 months follow up.ConclusionsPrevious reports described the use of 5-ALA to identify tumour cells within the solid component of cystic haemangioblastomas as well as in cystic ependymomas where the cystic component does not fluoresce. In our patient, the homogeneous fluorescence of the wall suggested that this was indeed a different entity from a haemangioblastoma or an ependymoma because of the different pattern of fluorescence observed. 5-ALA-assisted resection of cystic lesions should be considered when a tumoral origin is uncertain.

Abstract
ObjectivesTo understand the risk factors for and patterns of progression of low grade glioma (LGG).DesignSingle centre retrospective cohort study.SubjectsPatients undergoing at least two neurosurgical procedures for LGG, the first being for diffuse LGG (WHO 2). 22 patients included (14M; 8F); mean age at time of first operation 37.7±2.7 years. 20 patients had a Performance Status (PS) 0–1 and 2 patients had a PS 2.MethodsAll patients with LGG diagnosed in between 2009–2018 were retrospectively evaluated. Variables of interest included demographics, staging, performance status, time to re-operation (TTR), extent of resection, molecular genetics (1p19q co-deletion, IDH status). Tumour volumes were estimated from MRI images by the validated ABC/2 equation. Statistical analyses were performed by Stata13.0.ResultsThe tumour progressed in WHO grade in 18 patients (WHO grade 3 (n=15); WHO grade 4 (n=3). Mean time to re-operation after the first surgery was 7.0±1.2 years following gross total resection (GTR) and 3.2±0.7 years following subtotal resection (STR). Non-adjusted analysis of risk factors for time to re-operation (TTR) showed absence of 1p19q co-deletion as a risk factor (p=0.021). Adjusted analysis revealed that GTR, 1p19q mutation, PS 0 at 1 st surgery and tumour volumetric change decrease the risk for re-intervention (p<0.05). Chemo-radiotherapy was not associated with TTR.ConclusionsIn our cohort, TTR in LGG was influenced by the amount of initial resection, 1p19q deletion, PS and post-operative volumetric change.

Abstract
ObjectivesTo review the risk factors and patterns of progression/recurrence of low grade glioma (LGG).DesignSystematic review of the published literature.SubjectsInclusion criteria were peer reviewed publications of cohort studies of recurrent/progressive LGG. Studies of wider populations were included if relevant LGG data could be analysed separately.MethodsMedline and Cochrane databases were searched using MeSH and non-MeSH terms, including ‘glioma’, ‘astrocytoma’, ‘oligoastrocytoma’, ‘diffuse glioma’, ‘oligodendroglioma’, ‘low grade’ and ‘disease recurrence’ by two independent reviewers.ResultsOverall, 917 studies were screened, of which 57 studies met the inclusion criteria. The most frequently described risk factor for recurrent LGG was suboptimal extent of resection (EOR) of the initial tumour (in 20 studies); recurrence was also associated with the patient’s age (2), tumour location (4), neurological status (3), tumour volume (6), bihemispherical tumour (3) and astrocytic histology (6). IDH mutation was associated with recurrence in 1 out of 3 studies, but TP53 mutation (2 of 4) and MGMT methylation status (4) were not. Malignant transformation was associated with TP53 mutations (3), IDH mutation (1) and EOR (1). Favourable progression free survival (PFS) and/or overall survival (OS) were associated with greater EOR (16), oligodendroglioma histology (2 of 4), initial KPS (3) and the use of adjuvant therapies (9 of 14). IDH mutation was associated with improved PFS and OS (3 of 4). TP53 mutation improved PFS in 1 of 3 studies. MGMT methylation and 1 p/19q codeletion may predict treatment response but their effects on survival are unclear.ConclusionsAstrocytoma histology, IDH and TP53 mutation statuses and surgical treatment (EOR) are essential in determining the time to recurrence or progression in LGG.

Abstract
AIM The purpose of this work is to evaluate if the asymmetry of venous outflow between the two hemispheres is a reliable criterion of impairment of the cerebral vascular reserve among symptomatic patients harbouring a spontaneous atherosclerotic occlusion of internal carotid artery. METHODS From January 1995 to December 2007, 7 symptomatic patients, affected from occlusion of internal carotid artery, were submitted to a low-flow by-pass between the superficial temporal artery and the middle cerebral artery owing to the presence of an impairment of cerebral vascular reserve diagnosed by TC-Doppler, SPECT or perfusion-CT with acetazolamide challenge. Conventional angiography was always performed. Angiographic studies of these patients were reviewed in order to find out the presence of asymmetry of the venous outflow. In the same period 35 patients harbouring an occlusion of the carotid artery in the neck and a normal cerebral reserve underwent cerebral angiography in our departments in Monza. Angiographic studies, of this latter group of patients, were also retrospectively analyzed with the same purpose. RESULTS All patients, with a poor cerebral reserve, showed an asymmetry of venous outflow >3 s omolateral at the carotid occlusion. Patients, with a normal cerebral reserve, showed an asymmetry of venous outflow <2 s. CONCLUSIONS Asymmetry of venous outflow were correlated to an impaired cerebral reserve also in chronic conditions as atherosclerotic spontaneous occlusion of internal carotid artery. Our data are a further support to the reliability of this criterion in case of therapeutic sacrifice of internal carotid artery.

Abstract
Extradural motor cortex stimulation (EMCS) has been proposed as alternative to deep brain stimulation (DBS) in the treatment of Parkinson's disease (PD). Its mechanisms of action are still unclear. Neuroimaging evidenced motor cortical dysfunction in PD that can be reversed by therapy. We performed left hemisphere EMCS surgery in six advanced PD patients fulfilling CAPSIT criteria for DBS with the exception of age >70 years. After 6 months, we measured regional cerebral blood flow (rCBF) at rest with SPECT and Tc-99m cysteinate dimer bicisate off-medication with stimulator off and on. Clinical assessment included Unified Parkinson's Disease Rating Scale part II and III, Abnormal Involuntary Movement Scale and mean dopaminergic medication dosage. We used statistical parametric mapping for imaging data analysis. Clinically we observed no mean changes in motor scales, although blinded evaluation revealed some benefit in individual patients. We found significant rCBF decrements in the pre-central gyrus, pre-motor cortex and caudate nucleus bilaterally, left prefrontal areas and right thalamus. Perfusion increments were found in cerebellum bilaterally. EMCS determined significant modulation of neuronal activity within the cortico-basal ganglia-thalamo-cortical motor loop in our cohort of advanced PD patients. However, these effects were paralleled by mild and variable clinical efficacy.

Abstract
Esthesioneuroblastoma is a rare malignant neoplasm arising in the nasal cavity. Huge esthesioneuroblastomas, extending into the ethmoid roof and the cribriform plate, or invading the anterior cranial fossa, have traditionally been treated by craniofacial resection. Because of the invasiveness and potentially disfiguring results of a transfacial approach, a new technique has been proposed, combining endoscopic nasal and anterior craniotomy resection. We describe the case of a young male presenting with a large esthesioneuroblastoma involving the nasal cavity and the anterior cranial fossa, causing a huge skull base destruction. A combined transcranial and endoscopic nasal resection resulted in a macroscopically total removal of the tumor. The operative technique is reviewed in detail, along with the method used for the reconstruction of the anterior skull base defect.

Abstract
A decline in verbal fluency is the most consistent neuropsychological sequela of deep brain stimulation (DBS) for Parkinson's disease. We assessed clinical correlates and switching and clustering subcomponents in 26 parkinsonians undergoing subthalamic DBS. Post-surgical motor improvement was accompanied by worsening at both letter and category fluency tasks. Total number of words and switches decreased, while average cluster size was unchanged. Worsening tended to be prominent in patients with baseline poorer cognitive status and more depressed mood. Impairment of shifting suggests prefrontal dysfunction, possibly due to disruption of fronto-striatal circuits along the surgical trajectory and/or to high frequency stimulation itself.

Abstract
The headache is a very frequent symptom and represents the 0.36%-2.5% of all reasons of claim to Emergency Department. Even if it is rarely related to high risk diseases, it is mandatory to promptly differentiate life-threatening conditions. In order to establish a correct diagnostic and therapeutic pathway and ask for aimed specialistic consultation, the emergency physician must be familiar with the various categories of headache. It is important to distinguish between essential headache and secondary headache. All patients presenting to the emergency department with the complaint of headache should be interviewed carefully regarding their history. The quality of pain associated with the intensity, location, rate, duration, modality of onset, relieving or worsening conditions, response to drugs, symptoms or signs associated must be investigated as well. Careful neurological examination including the vision of fundus oculi and the evaluation of rigor nucalis can provide further important diagnostic information. Laboratory exams do not usually give significant issues in the majority of patients with headache. However, dosage of inflammation index can be useful when an infective or inflammatory disease is suspected. CT scan can rule-out the suspicion of organic intracranial causes. When the physician suspects meningitis or subarachnoid hemorrhage (SAH) not showed by CT scanning, rachicentesis can turn out diagnostic. The modality of onset, clinical characteristics and differential diagnosis of subarachnoid hemorrhage, intracranial hypertension, colloidal cyst of the third ventricle, trigeminal neuralgia, temporal arteritis and pituitary adenomas and apoplexy will be discussed. These diseases are not only of neurological and neurosurgical interest, but involve also the physician in the Emergency Department.
