Introduction: Symptomatic chronic subdural hematomas (CSDH) remain one of the most frequent diagnoses in current neurosurgical practice. Burr-hole craniostomy with irrigation and placement of close-system drainage is the current recommended surgery for symptomatic CSDH. The aim of this study is to perform a direct comparison between two surgical techniques in the treatment of symptomatic CSDH, which have been proven in previous studies to be efficient. Our main objective was to compare the efficacy of placement of a subperiosteal drain (SPD) and a subdural drain (SDD) following single burr-hole craniostomy and irrigation, and to demonstrate any significant differences in terms of overall surgical complications, functional outcome at three months and mortality rate. Materials and Methods: The study was carried out in two local neurosurgical centres. The SPD group was performed in Hospital Umum Sarawak (HUS) and the SDD group was performed in Hospital Sultanah Aminah Johor Bahru (HSAJB), from 1 January 2012 till 30 January 2014 with a total of 30 patients in both treatment groups. Results: Overall, there were no statistically significant difference in terms of patient general characteristics, pre-operative and post-operative symptoms, Markwalder grades, postoperative hematoma volume and recurrence, mortality and functional outcome at discharge and at three month follow-up between both groups. Albeit not achieving statistical significance, we observed a lower rate of surgical complication especially for post-operative intracranial hematoma with placement of the SPD system. Conclusions: Our study concludes that both treatment methods proved to be highly effective in the treatment of CSDH. However, with a lower overall surgical complication rate, treatment with single burr-hole craniostomy, irrigation and placement of the SPD system can be considered a treatment of choice for the management of symptomatic CSDH.

Introduction: Computed tomography (CT) is the preferred diagnostic toolkit for head and
brain imaging of head injury. A recent development is the invention of a portable CT scanner that
can be beneficial from a clinical point of view.
Aim: To compare the quality of CT brain images produced by a fixed CT scanner and a
portable CT scanner (CereTom).
Methods: This work was a single-centre retrospective study of CT brain images from
112 neurosurgical patients. Hounsfield units (HUs) of the images from CereTom were measured
for air, water and bone. Three assessors independently evaluated the images from the fixed
CT scanner and CereTom. Streak artefacts, visualisation of lesions and grey–white matter
differentiation were evaluated at three different levels (centrum semiovale, basal ganglia and
middle cerebellar peduncles). Each evaluation was scored 1 (poor), 2 (average) or 3 (good) and
summed up to form an ordinal reading of 3 to 9.
Results: HUs for air, water and bone from CereTom were within the recommended
value by the American College of Radiology (ACR). Streak artefact evaluation scores for the fixed
CT scanner was 8.54 versus 7.46 (Z = -5.67) for CereTom at the centrum semiovale, 8.38 (SD =
1.12) versus 7.32 (SD = 1.63) at the basal ganglia and 8.21 (SD = 1.30) versus 6.97 (SD = 2.77) at
the middle cerebellar peduncles. Grey–white matter differentiation showed scores of 8.27 (SD =
1.04) versus 7.21 (SD = 1.41) at the centrum semiovale, 8.26 (SD = 1.07) versus 7.00 (SD = 1.47) at
the basal ganglia and 8.38 (SD = 1.11) versus 6.74 (SD = 1.55) at the middle cerebellar peduncles.
Visualisation of lesions showed scores of 8.86 versus 8.21 (Z = -4.24) at the centrum semiovale,
8.93 versus 8.18 (Z = -5.32) at the basal ganglia and 8.79 versus 8.06 (Z = -4.93) at the middle
cerebellar peduncles. All results were significant with P-value < 0.01.
Conclusions: Results of the study showed a significant difference in image quality
produced by the fixed CT scanner and CereTom, with the latter being more inferior than the
former. However, HUs of the images produced by CereTom do fulfil the recommendation of the
ACR.

Background: Mortality and morbidity associated with intracerebral HemorrhageICH is still high. Up to now, there are no evidence-based effective treatments for acute ICH. This study is to assess the effect of tranexamic acid (TXA) on hematoma growth of patients with spontaneous ICH compared to a placebo.
Methods: We performed a single-blinded, randomised placebo-controlled trial of TXA (intravenous 1g bolus, followed by infusion TXA 1 g/hour for 8 hours) in acute (< 8 hours) primary ICH. Strict blood pressure control (target SBP 140-160 mmHg). A repeat Computed Tomography brain was done after 24 hours to reassess hematoma growth. The primary objective is to test the effect of TXA on hematoma growth. Other objective was to test the feasibility, tolerability, and adverse events of TXA in primary ICH.
Results: Statistical analysis showed significant hematoma growth in control group after 24 hours compared to baseline (14.3300 vs 17.9940, P = 0.001) whereas the treatment group there is no significant hematoma size expansion between baseline and after 24 hours (P = 0.313).
Conclusions: This study showed a significant hematoma volume expansion in the control group compared to the treatment group.

Interleukin 31 (IL-31)is one of the cytokines which appears to be an important regulator of Th2 responses. Previous study has been done to determine IL-31 serums levels in atopic dermatitis (AD). However, the serum levels of IL-31 in allergic rhinitis (AR) and atopic asthma (AA) is not many reported and still unclear. The objective of this cross sectional study is to determine an association between IL-31 and other predisposing factors with allergic diseases in HRPZ II (Hospital Raja PerempuanZainab II) and HUSM (Hospital UniversitiSains), Kelantan, Malaysia. This study involved 70 patients of AD, 70 patients of AR, 70 patients of AA and 70 healthy controls from staffs and people in HUSM.Five milliliters of blood were withdrawn and centrifuged for 5 minutes at 2000 rpm to obtain the serum and analyzed for IL-31 levels by using enzyme-linked immunosorbent (ELISA) kits (Human IL 31 Duoset, R&D System). Simple and multiple logistic regressions were used to analyze the association between IL-31 levels and predisposing factors among allergic diseases. The levels of IL-31 and other predisposing factors showed significant associations in smoking status, occupational exposure and area of living for AD and AR, however in AA, the significant association only found in smoking status and occupational exposure. In conclusion, we found that there were associations between IL-31 serum levels and other predisposing factors with AD, AR and AA. The findings can be the pilot study to determine IL-31 levels in allergic diseases in Malaysia.

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.

The incidence of neurenteric cyst (NC) is rare amongst spine tumors. It is most often asymptomatic but may present with sensory and motor symptoms. When associated with thoracic vertebra fusion it is not reported before, this complicates the placement of pedicle screw during posterior instrumentation. Herein, we report a case of thoracic spinal neurenteric cyst in a 40-year-old man that presents with chronic back pain, left lower limb weakness and numbness. Elective excision of NC over T6-T7 with laminectomy and multilevel posterior instrumentation was successfully performed with significant improvement of the symptoms. Neurenteric cyst is a rare spinal cord lesion which may cause permanent neurological sequalae. Complete surgical excision with spine fixation in this case provides good long-term outcome.
