This was a prospective observational study done to evaluate
the role of a repeat head CT in patients with mild traumatic brain injury. The aim was to evaluate wether the repeat head CT were useful in providing information that leads to any neurosurgical intervention. 279 adult patients with a mild head injury (GCS 13-15) were enrolled, and these comprised of patients with an initial traumatic intracranial haemorrhage not warranting any surgical intervention. All patients were
subjected to a repeat head CT within 48 hours of admission
and these showed no change or improvements of the brain
lesion in 217 patients (79.2%) and worsening in 62 patients
(20.8%). In thirty-one patients, surgical intervention was
done following the repeat head CT. All of these patients had a clinical deterioration prior to the repeat head CT. Even if a repeat head CT had not been ordered on these patients, they would have had a repeat head CT due to deteriorating neurological status. When the 62 patients with a worsening repeat head CT were compared with the 217 patients with an improved or unchanged repeat head CT, they were found to have older age, lower GCS on admission, presenting symptoms of headache, higher incidence of multiple traumatic intracranial pathology and lower haemoglobin level on admission. On stepwise multiple logistic regression analysis, three factors were found to independently predict a worse repeat head CT (Table IV). This includes age of 65 years or older, GCS score of less than 15 and multiple traumatic
intracranial lesion on initial head CT. As a conclusion, we
recommend that, in patients with a MTBI and a normal
neurological examination, a repeat cranial CT is not indicated, as it resulted in no change in management or neurosurgical intervention. Close monitoring is warranted in a subset of patients with risk factors for a worsening repeat head CT.

Introduction: The annual incidence of intracranial aneurysm in Malaysia is estimated
to be 1.1–1.7 per 100,000 population based on a study done conducted in 1988. Since then, little
epidemiological research has been conducted in Malaysia, and the real incidence is therefore
probably unreported despite advancements in the diagnosis and treatment of this disorder.
Intracranial aneurysm may be treated by microsurgical clipping or embolisation depending on its
location and the surgeon’s preference. This study aims to report the characteristics and outcomes
of patients with a clipped anterior circulation aneurysm in Hospital Sungai Buloh.
Methods: We retrospectively collected the data of patients with anterior circulation
aneurysms who underwent clipping from 1 January 2013 until 30 June 2014 in Hospital Sungai
Buloh.
Results: The mean age of the patients was 48.9 years old, and 56.7% of the study
population were male and 63.3% were Malay. There were almost equal numbers of patients with
(46.7%) and without (53.3%) co-morbidities such as hypertension and ischaemic heart disease.
Half of the study population fell under Fisher grade 3 (50.0%), whereas 46.7% were Fisher grade
4. With respect to the Navarro score, 20% of patients scored 10, 16.7% scored 5 or 7, 13.3% scored
11, 10% scored 9, 6.7% scored 1 and 3.3% scored 2, 3 or 8. Most of the patients fell under grade
I (33.3%) of the World Federation of Neurological Societies grading (WFNS), and the fewest
number of patients were grade III (3.3%). Most (56.7%) patients had an intracranial aneurysm
located at the anterior communicating artery (ACOM), followed by the anterior cerebral artery
(ACA) and the middle cerebral artery (MCA) (16.7% each), the posterior communicating artery
(PCOM) (6.7%) and, finally, the internal carotid artery (ICA) (3.3%). Neurological outcomes at
three and six months were assessed using the Modified Rankin Scale (mRS). At three months
follow-up, the majority of the participants (33.3%) scored 0 or 6, whereas at six months follow-up,
the majority scored 0 (43.3%).
Conclusion: The main characteristics of patients in Hospital Sungai Buloh were that they
were in their 40s and mostly Malays without any known comorbidities. Although the majority
of patients had high Fisher grades, their outcomes post intervention were promising. However,as data collected from Hospital Sungai Buloh may not be representative of the whole country, a
larger-scale data collection is necessary to create our own database and to identify the risks
factors that are exclusive to our country, if present.

CNS malignant astrocytoma has a descending frequency of
occurrence according to site; moving from intracranial to
cervical-medullary, thoracic, lumbar and extremely rare in
the conus medullaris. IMSC glioblastoma are rare and de
novo conus medullaris GBM is an extreme rarity. The
duration of symptoms is short and the neurological & clinical
deterioration are rapid. Despite aggressive treatment via
surgery and radiotherapy IMSC & conus GBM still carry a
grim and fatal prognosis. This is a strong motivation for
developing new treatment strategy. New treatment modality
like Temozolomide & gene therapy is currently in under studyand long term result is under study and review.

Background: Brain ischaemia and infarction are the leading factors in morbidity and
mortality of traumatic brain injury. This study aimed to determine the perfusion status of
pericontusional hypodense areas in traumatic cerebral contusion
Methods: Ten patients involved in motor vehicle accidents were enrolled in this study,
and contusions were diagnosed from plain computed tomography scans of the brain. Subsequent
computed tomography perfusion (CTP) was performed to analyse the perfusion of pericontusional
hypodense areas, which were divided into 4 regions of interest (ROI).
Results: Most ischaemic perfusion was found in ROI 6 (affecting 60% of patients), although
the mean of the perfusion parameters were normal. A significant positive correlation was found
between the perfusion status in the pericontusional area nearest to the skull vault (ROI 3) and its
distance/thickness to the skull vault (r = 0.698, P = 0.025). Two adjacent pericontusional hypodense
areas (ROI 4 and ROI 5) showed a significant positive correlation with each other (r = 0.667, P =
0.035) in terms of perfusion status. The presence of a hypodense pericontusional area is suggestive
of oedema and perfusion disturbances.
Conclusion: CTP is a useful, fast, and appropriate method in evaluating perfusion of
pericontusional hypodensity area that may help the treating physician to provide an appropriate
treatment to the patient.

A prospective cohort study was done to evaluate the role of surgery in patients with spontaneous supratentorial intracerebral haemorrhage (SICH) and to identify
predictors of outcome including the use of invasive regional cortical cerebral blood flow (rCoBF) and microdialysis. Surgery consisted of craniotomy or decompressive craniectomy. The ventriculostomy for intracranial pressure (ICP) monitoring and
drainage and regional cortical cerebral blood flow (rCoBF) and microdialysis were performed in all subjects. Pre and post operative information on subjects were
collected. The study end points was functional outcome at 6 months based on a dichotomised Glasgow Outcome Scale (GOS).The selected clinical, radiological,
biochemical and treatment factors that may influence the functional outcome were analysed for their significance. A total of 36 patients were recruited with 27(75%)
patients had Glasgow Coma Score (GCS) between 5 to 8 on admission and 9(25%) were admitted with GCS of 9. At 6 months, 86 % had a poor or unfavourable
outcome (GOS I-III) and 14% had good or favourable outcome (GOS IV-V). The mortality rate at 6 months was 55%. Univariate analysis for the functional outcome
identified 2 significant variables, the midline shift (p=0.013) and mean lactate:pyruvate ratio (p=0.038). Multivariate analysis identified midline shift as
the single significant independent predictor of functional outcome (p=0.013).Despite aggressive regional cortical cerebral blood flow (rCoBF) and microdialysis study
for detection of early ischemia, surgical treatment for spontaneous intracerebral haemorrhage only benefited a small number of patients in terms of favourable
outcome (14%) and in the majority of patients (86%), the outcome was unfavourable. Patients with midline shift > 5mm has almost 21 times higher chances
(adj) OR 20.8 of being associated with poor outcome (GOS I-III).

Deep brain stimulation (DBS) was first introduced in 1987 to the developed world. As a
developing country Malaysia begun its movement disorder program by doing ablation therapy
using the Radionics system. Hospital Universiti Sains Malaysia a rural based teaching hospital had
to take into consideration both health economics and outcomes in the area that it was providing
neurosurgical care for when it initiated its Deep Brain Stimulation program. Most of the patients
were from the low to medium social economic groups and could not afford payment for a DBS
implant. We concentrated our DBS services to Parkinson's disease, Tourette's Syndrome and
dystonia patients who had exhausted medical therapy. The case series of these patients and their
follow-up are presented in this brief communication.

Awake craniotomy is a brain surgery in patients who are
kept awake when it is indicated for certain intracranial
pathologies. The anaesthetic management strategy is very
important to achieve the goals of the surgery. We describe a series of our first four cases performed under a combination of scalp block and conscious sedation. Scalp block was performed using a mixture of ropivacaine 0.75% and adrenaline 5 μg/ ml administered to the nerves that
innervate the scalp. Conscious sedation was achieved with
a combination of two recently available drugs in our country, dexmedetomidine (selective α 2-agonist) and remifentanil (ultra-short acting opioid). Remifentanil was delivered in a target controlled infusion (TCI) mode.

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.

Background: Ruptured cerebral aneurysm is a life-threatening condition that requires urgent medical attention. In Malaysia, a prospective study by the Umum Sarawak Hospital, Neurosurgical Center, in the year 2000–2002 revealed an average of two cases of intracranial aneurysms per month with an operative mortality of 20% and management mortality of 25%. Failure to diagnose, delay in admission to a neurosurgical centre, and lack of facilities could have led to the poor surgical outcome in these patients. The purpose of this study is to identify the factors that significantly predict the outcome of patients undergoing a surgical clipping of ruptured aneurysm in the local population. Material and Method: A single center retrospective study with a review of medical records was performed involving 105 patients, who were surgically treated for ruptured intracranial aneurysms in the Sultanah Aminah Hospital, in Johor Bahru, from July 2011 to January 2016. Information collected was the patient demographic data, Glasgow Coma Scale (GCS) prior to surgery, World Federation of Neurosurgical Societies Scale (WFNS), subarachnoid hemorrhage (SAH) grading system, and timing between SAH ictus and surgery. A good clinical grade was defined as WFNS grade I–III, whereas, WFNS grades IV and V were considered to be poor grades. The outcomes at discharge and six months post surgery were assessed using the modified Rankin’s Scale (mRS). The mRS scores of 0 to 2 were grouped into the “favourable” category and mRS scores of 3 to 6 were grouped into the “unfavourable” category. Only cases of proven ruptured aneurysmal SAH involving anterior circulation that underwent surgical clipping were included in the study. The data collected was analysed using the Statistical Package for Social Sciences (SPSS). Univariate and multivariate analyses were performed and a P-value of < 0.05 was considered to be statistically significant. Result: A total of 105 patients were included. The group was comprised of 42.9% male and 57.1% female patients. The mean GCS of the patients subjected to surgical clipping was 13, with the majority falling into the good clinical grade (78.1%). The mean timing of the surgery after SAH was 5.3 days and this was further categorised into early (day one to day three, 45.3%), intermediate (day four to day ten, 56.2%), and late (after day ten, 9.5%). The total favourable outcome achieved at discharge was 59.0% as compared to 41.0% of the unfavourable outcome, with an overall mortality rate of 10.5%. At the six-month post surgery review (n = 94), the patients with a favourable outcome constituted 71.3% as compared to 28.7% with an unfavourable outcome. The mortality, six months post surgery was 3.2%. On a univariate analysis of early surgical clipping, patients with a better GCS and good clinical grade had a significantly better outcome at discharge. Based on the univariate study, six months post surgery, the timing of the surgery and the clinical grade remained significant predictors of the outcome. On the basis of the multivariate analysis, male patients of younger age, with a good clinical grade, were associated with favourable outcomes, both at discharge and six months post surgery. Conclusion: In this study, we concluded that younger male patients with a good clinical grade were associated with a favourable outcome both at discharge and six months post surgery. We did not find the timing of the surgery, size of the aneurysm or duration of surgery to be associated with a patient’s surgical outcome. Increasing age was not associated with the surgical outcome in a longer term of patient’s follow up.

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.
