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.

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: 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.

Aims:
Metarhizium anisopliae is an entomopathogenic fungus (EPF) that exists naturally in the environment and
potentially be used as a biological control agent against many insect pests. This study aims to evaluate the effect of
nutrient additives on the yield and viability of M. anisopliae spore and to determine the optimum incubation period for
maximum spore production.
Methodology and results:
In this study, M. anisopliae was cultivated by solid-state fermentation using rice as a growth
medium. Three different nutrient additives were examined which aimed to maximize the production of M. anisopliae
spores. Among the three nutrient additives evaluated, yeast (1.84 ± 0.04 g) supported better growth and spore
production than molasses (0.58 ± 0.04 g) and palm oil (0.47 ± 0.09 g). The incubation period between 2-6 weeks
produced higher spore yield (0.97 ± 0.02 g spores) at week 4 with a better spore viability (86.30 ± 0.45%) at week 2.
Conclusion, significance and impact of study
Hence, it is suggested that the optimum incubation period is between
2 and 6 weeks after inoculation, and M. anisopliae could be mass produced in large quantities on rice substrate with the
addition of yeast as the nutrient additives.
