Brain energy is associated commonly with electrochemical type of energy. This energy is displayed in the form of electromagnetic waves or better known as brainwaves. This concept is a classical concept (Newtonian) in which the studied object, that is the brain is viewed as a large anatomical object with its functional brainwaves. Another concept which incorporates quantum principles in it can also be used to study the brain. This perspective viewing the brain as purely waves, including its anatomical substrate. Thus, there are two types of energy or field exist in our brain: electromagnetic and quantum fields. Electromagnetic field is thought as dominant energy in purely motor and sensory inputs to our brain, whilst quantum field or energy is perceived as more influential in brain cognitions. The reason for this notion lies in its features which is diffused, nondeterministic, varied, complex and oneness.

General Hospital. In all 167 of them wereadministered with TXA and another 167 of the patients werenot. The primary outcome expected is the number of goodoutcomes in isolated TBI patients given TXA. Goodoutcome is defined by Glasgow Outcome Score-Extended(GOSE) of five and above. Secondary outcome was clotexpansion of an intracranial bleed seen on the first scan thathad expanded by 25% or more on any dimension on thesecond scan. Results: The TXA did not show significant trend of goodoutcome in terms of GOSE (p=0.763). However, for moderateand severe acute subdural haemorrhage (SDH) subgroups,there was a significant difference (p=0.042). Clot expansionwas present in 14 patients (12.7%) with TXA given and in 54patients (38.8%) without TXA. The difference wasstatistically significant (p<0.001). Of the patients whoreceived TXA, there was one case (0.6%) of deep veinthrombosis. Apart from that, TXA showed non-significanttrend in reducing mortality (p=0.474). Conclusions: Tranexamic acid reduces the rate of clotexpansion in TBI by 26.1% (38.8-12.7%) without significantlyincreasing the risk of a thrombotic event. It can also improvethe outcome of moderate and severe TBI patients with acuteSDH.

mesodermal origin and is commonly associated withsyringomyelia. Foramen magnum decompression is thefirst-line of standard treatment in symptomatic patients witha confirmed radiographic diagnosis. Magnetic resonance(MR) cine allows accurate evaluation of cerebrospinal fluid(CSF) physiology at the craniovertebral junction but oftenthis is under-utilised in Malaysia. Methods: In this series, we looked into nine cases of CM withsyringomyelia from clinical and radiological perspectivebefore and after surgery. The radiological parameters wereherniated tonsillar length, syrinx: cord ratio, syrinx lengthand diameter. Flow velocity and morphologic changes inChiari were illustrated. Results: Seven patients showed either reduction in syrinxlength, syrinx: cord ratio or both postoperatively. Clinicalrecovery somewhat varied in motor and sensory symptoms.Four patients gained better functional grade in modifiedRankin scale (MRS) while the rest remained similar. Thestudy highlighted the advantage of CSF flow dynamicsinformation over MR anatomical radiographic improvementin addressing the neurologic and functional recovery. Wealso discussed the practicality of cine sequence inpreoperative patient selection, syrinx analysis andpostoperative flow evaluation in anticipation of clinicaloutcome. Conclusion: Phase-contrast cine MRI is a useful tooldictated by resource availability. We recommend its routineuse in preoperative analysis and subsequent observationalfollow-up after surgery.

Although the precise etiology of Glioblastoma multiforme (GBM, WHO grade IV) remains unknown, its progression is believed to be driven by the accumulation of multiple genetic alterations. Here, we report a case of a patient who developed GBM, and associated with dual alterations, particularly 4977-bp deletion in mtDNA (mtDNA4977) and p.Arg132His (R132H) mutation in IDH1. A 35-year old Malaysian woman patient who primary diagnosed with astrocytoma WHO grade I and subsequently after four years developed a GBM, was detected with a mtDNA4977. This deletion appears to be a sporadic mutation. Additionally, analysis of patient’s tumor tissue also found to harbor a heterozygous IDH1 R132H mutation. This represents the first case report of coexisting mtDNA4977 together with IDH1 R132H mutation in a Malaysian patient of GBM. The findings of dual alterations could be of therapeutic benefit if these alterations were justified to be contributing to GBM growth and aggressiveness.

Introduction: Intracranial brain tumour like meningiomas and glioblastomas are most prevalent tumour. The metastasis to the brain is one of the major issues in the tumours of the central nervous system. The diagnosis of metastatic and primary brain tumour is incomprehensible with standard magnetic resonance imaging (MRI). The magnetic resonance spectroscopy (MRS) is basically performed in standard clinical setting for diagnosing and tracking the brain tumour. Method: It is a retrospective study containing 53 patients with MRS. The patients with metastatic tumour (n=10), glioblastomas (n=8) and meningiomas (n=20) are included in the study. Single voxel technique is applied in the tumour core to determine the metabolites. The tumour N-acetyl aspartate (NAA), Choline (Cho), Creatine (Cr), Lactate, Alanine and lipids were analysed. The ratios of NAA/Cr, Cho/NAA and Cho/Cr were recorded and compared between the three tumours. The metabolites were detected between short echo time (TE) to long echo time (TE) during MRS. Results: There is a sharp fall of NAA peak in metastatic tumour. The resonance of creatine, lactate and alanine is higher in glioblastomas. A high lipid mean value of 3.13(0.17) is seen in metastatic tumour. The ROC curve shows a low NAA/Cr specificity of 46.7%, high sensitivity of 83.3% in Cho/NAA and Cho/Cr ratio. Conclusion: The metabolic profiles of metastatic brain tumour, glioblastomas and meningioma illustrate a divergence in their description that will assist in planning therapeutic and surgical intervention of these tumours.

Background: There has been increasing evidence showing that stingless bee honey exhibits anti-oxidant, anti-inflammatory and anti-cancer properties. Pharmacologically-active components in honey such as flavonoids and phenolic constituents are known to contribute to its medicinal benefits. To the best of our knowledge, this is the first study on evaluating anticancer effects of locally-produced Malaysian stingless bee honey from Heterotrigona itama sp. on malignant glioma cells. Methods: Proliferation and apoptosis studies of U-87 MG cells following stingless bee honey treatment were carried out using MTS assay and acridine orange/propidium iodide dual staining, respectively. Results: Results demonstrated time and dose-dependent cytotoxicity using 0.625%, 1.25% and 10% stingless bee honey (P < 0.05). IC50 values were calculated using cells treated with 10% stingless bee honey. It was also observed that 10% stingless bee honey induced nuclear shrinkage, chromatin condensation and nucleus fragmentation, indicating that cellular changes were consistent with the apoptotic characteristics of the cells. Conclusion: These data provide a good basis for further evaluation of the medicinal properties of stingless bee honey from Heterotrigona itama sp. This source of honey may serve as a potential therapy for malignant glioma.

Background: Ventriculoperitoneal (VP) shunting is a permanent form of cerebrospinal fluid (CSF) diversion that can be performed for hydrocephalus. Sterility of the CSF is an important prerequisite for permanent shunt placement. It has been hypothesised that in early stage of meningitis, ventricular CSF remains sterile. A study is conducted on the first CSF sample taken from patients suspected to have meningitic hydrocephalus. Method: A retrospective review case records of patients who had undergone external ventricular drainage (EVD) for suspected meningitic hydropcephalus in Hospital Sultanah Aminah Johor Bahru (HSAJB), Johor, Malaysia. Results: Fifty-one cases were analysed. Mean age of patients was 37.27 years old, with 64.7% of them was male. Univariate analysis revealed that the main parameters to determine CSF sterility were CSF glucose (95% CI, 0.852, 10.290, P = 0.001), CSF protein (CI 95%, 0.722, 14.898, P < 0.001), CSF gram stain (95% CI, 16.437, 0.877, P < 0.001 ) and CSF appearance ( 0.611, 6.362, P = 0.012). Multivariate analysis had proven that gram stain was the main parameter in the CSF analysis (CI 95%, 16.437, 0.029, P = 0.016). No significant differences in CSF results were observed from EVD and lumbar puncture. Conclusion: The most significant parameter in CSF to determine infection was gram stain.

Background: With teleneurosurgery, more patients with head injury are managed in the primary hospital under the care of general surgical unit. Growing concerns regarding the safety and outcome of these patients are valid and need to be addressed.Method: This study is to evaluate the outcome of patients with mild head injury which were managed in non-neurosurgical centres with the help of teleneurosurgery. The study recruits samples from five primary hospitals utilising teleneurosurgery for neurosurgical consultations in managing mild head injury cases in Johor state. Two main outcomes were noted; favourable and unfavourable, with a follow up review of the Glasgow Outcome Scale (GOS) at 3 and 6 months.Results: Total of 359 samples were recruited with a total of 11 (3.06%) patients have an unfavourable. no significant difference in GOS at 3 and 6 months for patient in the unfavourable group (P = 0.368).Conclusion: In this study we have found no significant factors affecting the outcome of mild head injury patients managed in non-neurosurgical centres in Johor state using the help of teleneurosurgery.

Neuroplasticity has been subjected to a great deal of research in the last century. Recently, significant emphasis has beenplaced on the global effect of localized plastic changes throughout the central nervous system, and on how these changesintegrate in a pathological context. The present study aimed to demonstrate the functional cortical reorganization beforeand after surgery using magnetoencephalography (MEG) in a participant with brain tumor. Results of Visual EvokedMagnetic Field (VEF) based on functional MEG study revealed significantly different of MEG N100 waveforms before andafter surgery. Larger and additional new locations for visual activation areas after the surgery were found suggestingneuroplasticity. The present study highlight a physiological plasticity in a teenage brain and the alterations regardingneural plasticity and network remodeling described in pathological contexts in higher-order visual association areas.

The present study discussed functional reorganization and alteration in respond to the slow-growing tumour,hemangiopericytoma in the occipital cortex. Visual evoked field (VEF) and auditory evoked field (AEF) usingmagnetoencephalography (MEG) was used to evaluate the source localization and brain activity. Results of VEF sourcelocalization show a typical brain waves. Brain activity of the occipital lobe demonstrate low activation in the ipsilateralto the tumour. However, result shows the activation on the contralateral hemisphere was high and bigger in activationvolume. AEF result shows an identical source localization and both side of the temporal lobe are activated. This resultsuggests that there is a positive plasticity in auditory cortex and slow-growing tumour can induce functional reorganizationand alteration to the brain.
