A cross-sectional study was carried out at a medical centre to determine the cognitive profiles of 30 Parkinson’s disease patients with age of 69.76 ± 7.39 years. Thirty-seven percent of the patients were found to be at risk for dementia. The scores on subscales of working memory and alternating verbal fluency were significantly lower in Parkinson’s disease patients who were older than 77 years old. The scores on a subtest of working memory on the Parkinson’s Disease Cognitive Rating Scale (PDCRS) were significantly lower in Parkinson’s disease patients with a duration of illness of more than 10 years. In cognitive measurement, the subtests of verbal memory, delayed free recall and verbal fluency on the PD¬CRS were significantly lower in patients with less than six years of education. The patients who had difficulty with sustained attention, working memory and movement had significant anxiety and depression symptoms. In conclusion, multiple patterns in cognitive profiles influence the quality of life of patients with Parkinson’s disease in multi-dimensional ways.

Background & Objective: Helicobacter pylori infection has been associated with extradigestive diseases
including epilepsy. The main aim of the study was to determine the prevalence of Helicobacter
pylori using 13C urea breath test (UBT) in epilepsy patients in a teaching hospital in Malaysia and
compared to control. Methods: The study subjects were epilepsy patients from the neurology clinic
in a teaching hospital. The study was conducted from August 2010 to February 2011. The control
consisted of healthy individuals matched for age and gender, not on any acid suppression medications
and antibiotics. All subjects underwent UBT as per protocol. Variables such as age, race, household
income, types of epilepsy, duration of epilepsy, number of antiepileptic drugs, prognosis were analysed.
Good prognosis was defi ned as seizure free for 3 years. Results: Forty eight epilepsy patients and 47
control subjects were studied. Prevalence of H. pylori infection in the epilepsy patients was 37.5%
(n=18) and was 36.2% (n=17) in control. There were signifi cantly more subjects in the epilepsy
group with lower income. There were also more smokers in the epilepsy group but there was no
association between smoking and positive UBT. Epilepsy patients with poor prognosis have a higher
UBT positive rate compared to the good prognosis group (64.3% vs 35.7 %). However the difference
was not statistically signifi cant.
Conclusion: The prevalence of H. pylori infection in epilepsy patients is similar to that of the control
in this study involving Malaysian subjects.

The current coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) has led to a serious global health crisis. Increasing evidence suggests that elderly individuals with underlying chronic diseases, including Parkinson’s disease (PD), are particularly vulnerable to this infection. Changes in the routine care of PD patients should be implemented carefully without affecting the quality provided. The utilization of telemedicine for clinical consultation, assessment and rehabilitation has also been widely recommended. Therefore, the aim of this review is to provide recommendations in the management of PD during the pandemic as well as in the early phase of vaccination programs to highlight the potential sequelae and future perspectives of vaccination and further research in PD. Even though a year has passed since COVID- 19 emerged, most of us are still facing great challenges in providing a continuum of care to patients with chronic neurological disorders. However, we should regard this health crisis as an opportunity to change our routine approach in managing PD patients and learn more about the impact of SARS-CoV-2. Hopefully, PD patients can be vaccinated promptly, and more detailed research related to PD in COVID-19 can still be carried out.

A young man was admitted with sudden onset of right-sided weakness. He was assessed in the emergency department, and an immediate computed tomography (CT) perfusion study of the brain was arranged, which showed a left middle cerebral artery territory infarct with occlusion of the M1 segment. There was a significant penumbra measuring approximately 50% of the arterial territory. By the time his assessment was completed, it was 5.5 hours from the onset of symptoms. He was nonetheless administered intravenous recombinant tissue plasminogen activator (rtPA) based on the significant penumbra. He was discharged from the hospital after one week with significant residual deficit. At 2 months clinic follow-up, he showed almost complete recovery with a Modified Rankin Score of 1. We hope to demonstrate that a significant penumbra is an important determinant for good neurological recovery and outcome following stroke thrombolysis, even when patients present outside the 4.5 hours onset-to-treatment time window.

Background: Mutations in glucocerebrosidase (GBA) have been associated with the risk of developing
Parkinson’s disease (PD) in different ethnic populations. The prevalence of GBA mutations among
Malay PD patients is unknown. Thus, the aim of this study was to determine the frequency of GBA
mutations among Malay PD patients, focusing on early (EOPD) and late-onset (LOPD) patients.
Methods:EOPD (n = 50) and LOPD (n = 50) patients along with 50 ethnically and age-matched control wererecruited. The GBA exons of these patients were sequenced using the Ion Torrent PGMTM System.
Results: Five heterozygous mutations exclusive to EOPD patients were identified; c.-203A>G,p.S146L,
p.R159Q, p.L483P and p.L483R+c.-145G>A. In LOPD patients, c.543C>T(p.(F181=)), c.28-10C>A
and p.R202Q were identified in which this p.R202Q was also present in a control subject. In addition,
c.259C>A(p.(R87=)) and c.-145G>A were identified in two control subjects. In summary, we observed
GBA mutations in 8% and 6% of Malay PD cases and control subject, respectively. The prevalence
of GBA mutations was higher in EOPD (10%) than LOPD (6%). However, these differences were
not statistically significant; [PD vs. controls: OR = 1.36, 95%CI 0.35-5.38, p = 0.752] and [EOPD
vs. LOPD: OR = 1.74, 95%CI 0.39-7.71, p = 0.715].
Conclusion: We identified five exclusive heterozygous GBA mutations in EOPD patients which might
predict the increase susceptibility of Malays to develop PD at young age. These findings could add
knowledge into the existing evidences linking genetic alterations in GBA and PD.

Background and Objective: Intravenous thrombolysis service for stroke was introduced at the Universiti
Kebangsaan Malaysia Medical Centre (UKMMC) in 2009, based on the recommendations of a
multidisciplinary team of clinicians. We report the experience at our center in establishing a stroke
protocol incorporating computed tomography perfusion (CTP) of the brain, to assess the feasibility
of incorporating CTP in the stroke protocol.
Methods: A retrospective review of all patients who had a CTP between January 2010 and December
2011 was performed. Results: Of 272 patients who were admitted with acute ischemic stroke, 44
(16.2%) arrived within 4.5 hours from symptom onset and had a CTP performed with the intention to
treat. The median time for symptom-to-door, symptom-to-scan and door-to-scan was 90.0 minutes (62.5
– 146.3), 211.0 minutes (165.5 – 273.5) and 85.0 minutes (48.0 – 144.8) respectively. Eight patients
(2.9%) were thrombolysed of whom five received IV thrombolysis and three underwent mechanical
thrombolysis. The median symptom-to-needle and door-to-needle times were 290.5 minutes (261.3
– 405.0) and 225.0 minutes (172.5 – 316.8) respectively. Four patients were thrombolysed despite
being outside the window of treatment based on the CTP findings. Six of the thrombolysed patients
had a Modified Rankin Score (MRS) of 1-2 at 5 months post procedure.
Conclusions: CTP provides a benefit to management decisions and subsequent patient outcome. It is
feasible to incorporate CTP as a standard imaging modality in a stroke protocol. The delays in the
time-dependent pathways are due to our work flow and organisational process rather than performing
the CTP per se.

SUMMARY
Aim: This study was conducted to measure the cross
sectional area (CSA) of the ulnar nerve (UN) in the cubital
tunnel and to evaluate the role of high-resolution
ultrasonography in the diagnosis of ulnar nerve neuropathy
(UNN).
Materials and Methods This was a cross sectional study with
64 arms from 32 patients (34 neuropathic, 30 nonneuropathic).
Diagnosis was confirmed by nerve conduction
study and electromyography. The ulnar nerves were
evaluated with 15MHz small footprint linear array transducer.
The ulnar nerve CSA was measured at three levels with arm
extended: at medial epicondyle (ME), 5cm proximal and 5cm
distal to ME. Results from the neuropathic and nonneuropathic
arms were compared. Independent T-tests and
Pearson correlation tests were used. P value of less than
0.05 was considered significant.
Results: Mean CSA values for the UN at levels 5cm proximal
to ME, ME and 5cm distal to ME were 0.055, 0.109, 0.045 cm2
respectively in the neuropathic group and 0.049, 0.075, 0.042
cm2 respectively in the non-neuropathic group. The CSA of
the UN at the ME level was significantly larger in the
neuropathic group, with p value of 0.005. However, there was
no statistical difference between the groups at 5cm proximal
and distal to the ME, with p values of 0.10 and 0.35
respectively.
Conclusion: There is significant difference in CSA values of
the UN at ME between the neuropathic and non-neuropathic
groups with mean CSA value above the predetermined
0.10cm2 cut-off point. High-resolution ultrasonography is
therefore useful to diagnose and follow up cases of elbow
UNN.
