Over 100 articles related to stroke were found in a search
through a database dedicated to indexing all literature with
original data involving the Malaysian population between
years 2000 and 2014. Stroke is emerging as a major public
health problem. The development of the National Stroke
Registry in the year 2009 aims to coordinate and improve
stroke care, as well as to generate more data on various
aspects of stroke in the country. Studies on predictors of
survival after strokes have shown potential to improve the
overall management of stroke, both during acute event and
long term care. Stroke units were shown to be effective
locally in stroke outcomes and prevention of stroke-related
complications. The limited data looking at direct cost of
stroke management suggests that the health economic
burden in stroke management may be even higher.
Innovative rehabilitation programmes including braincomputer
interface technology were studied with
encouraging results. Studies in traditional complementary
medicine for strokes such as acupuncture, Urut Melayu and
herbal medicine were still limited.

Phenytoin is a widely prescribed antiepileptic agent for both focal and generalized seizure. We
report a case of a 20-year-old man with focal epilepsy presented with acute bilateral visual loss, and
delirium. His random phenytoin serum concentration on admission was 43.6 mg/L, well above the
recommended therapeutic range of 10-20 mg/L. Extensive investigations have ruled out other vascular
or demyelinating causes. His visual symptoms completely resolved after discontinuing phenytoin for
84 hours. This case shows that acute phenytoin toxicity can result in reversible visual failure.

Acute ischaemic stroke (AIS) is a devastating disease and one
of the leading causes of disabilities worldwide. From 2010 to
2014, the incidence of stroke in Malaysia had increased from
65 to 187 per 100,000 population.1 Thrombolytic therapy
with intravenous recombinant tissue plasminogen activator
(rtPA) within 4.5 hours of symptom onset has been shown to
be an effective treatment for AIS. Patients who receive
thrombolysis are 30 percent more likely to achieve excellent
functional outcome (modified Rankin scale of 0 to 1) at 3
months compared to placebo.2
Unfortunately, the delivery of stroke thrombolysis service in
Malaysia is often limited by the availability of neurologists.
To date, the ratio of neurologists capable of performing
thrombolysis serving in public hospitals to the Malaysian
population is 1:1.4 million.3 To counteract this disparity
and to cope with the increasing stroke burden in Malaysia,
there has been an advocacy for greater involvement of
non-neurologists, i.e., general and emergency physicians
in performing of stroke thrombolysis.4 Emerging data based
on short term outcomes appear to support this notion.
Based on a 2015 single center study on 49 AIS patients in
Australia, A. Lee et al., reported that there was no significant
difference in door to needle time, rates of symptomatic
intracranial bleeding (SICH), and mortality between patients
thrombolysed by neurologists versus stroke physicians.5
In
2016, a larger multicentre study in Thailand reported that
patients thrombolysed in hospitals without neurologists had
lower National Institute of Health Stroke Scale (NIHSS) scores
at discharge and lower inpatient mortality rate compared to
patients treated in neurologist hospitals.6 Based on these
short term outcomes, both studies suggest that nonneurologists are able to thrombolyse AIS patients safely and
effectively. Data comparing long term functional outcomes
in thrombolysis prescribed by neurologists and nonneurologists are still very limited.
The primary objective of this study was to evaluate and
compare the 3-month functional outcomes of thrombolytic
therapy between hospitals with and without on-site
neurologists. The secondary objective was to assess the doorto-needle time and complication rates of thrombolysis service
in both hospitals

Background and objectives: The cumulative time spent without medical intervention in acute stroke
patients may affect clinical outcomes. As the onset-to-arrival time to the hospital is crucial for effective
treatment interventions, this study aimed to explore the factors associated with pre-hospital delays
amongst acute stroke patients. Methods: We explored 932 patients data retrieved from the National
Neurology Registry of Seberang Jaya Hospital between January 2013 and December 2018. Data
on patient demographics and stroke manifestations were analysed using descriptive, univariate and
multivariate logistic regressions. Results: Most patients were men (62.9%) with an average age of
62 years old. In the final multivariate regression model, pre-hospital delay was significantly lower
among Chinese patients (aOR=0.6, 95% CI 0.4–0.9, p=0.016) and those using hospital ambulance
(aOR=0.4, 95% CI 0.3–0.7, p<0.001), but higher among patients with lacunar infarcts (aOR=2.5, 95%
CI 1.4–3.3; p<0.001). Conclusions: Demographic characteristic (ethnicity) and stroke manifestations,
particularly stroke subtypes, and mode of transport were mainly associated with pre-hospital delays
among acute stroke patients.
