Stigma is conceptually broad and culturally variable. Understanding stigma from the conceptual theories, culturally application based on the word stigma in other languages, the definition of stigma and its synonyms, as well as the medical implications in other stigmatized disease such as AIDS, will help us to understand the complexity of stigma in epilepsy. This review investigated the meaning and types of stigma from different perspectives, leading to staging stigma into 5 levels, i.e. social identity, stereotype, prejudice, discrimination and social disability. In addition to the conventional categorization of stigma into social, felt, self-perceived or internalized stigma, new categories of stigma i.e. personal and general attitudes towards epilepsy based on a newly developed Public Attitudes Toward Epilepsy (PATE) scale was introduced. Courtesy stigma was further elaborated in related to Asian culture. Based on well-established and recently developed theories, the causation and impact of epilepsy stigma was discussed in an Asian context, especially from the aspects of language and society values which are culturally specific. Integrating these theories of causation, illness and stereotype perceptions were proposed to be the mediating mechanism of stigma, which led to the development of a practical and multi-dimensional stigmatization model, aiming to guide, widen and deepen the scope of future stigma research in epilepsy. Using the established model, together with review of related studies, research priorities in epilepsy stigma research especially in Asia focusing on five aspects, i.e. expanding population studies especially on significant others, understanding stigma from personal attitude perspective, investigating the cultural and social causation of stigma, and the impacts of stigma on patients as well as the family members, were proposed.
Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region.
There are three major issues of ethical concern related to epilepsy care in the developing world. First, is it ethical for a developing country to channel its limited resources from direct epilepsy care to research? The main considerations in addressing this question are the particular research questions to be addressed and whether such research will bring direct benefits to the local community. Second, in a country with limited resources, when does ignoring the high treatment gap become an ethical issue? This question is of particular concern when the community has enough resources to afford treatment for its poor, yet is not providing such care because of gross wastage and misallocation of the national resources. Third, do countries with plentiful resources have an ethical responsibility to help relieve the high epilepsy treatment gap of poor countries? Indeed, we believe that reasonable health care is a basic human right, and that human rights transcend national boundaries. Although health care is usually the responsibility of the nation-state, many modern states in the developing world are arbitrary creations of colonization. There is often a long process from the establishment of a political-legal state to a mature functional nation. During the long process of nation building, help from neighboring countries is often required.
Background and objectives: Radiation treatment in nasopharyngeal carcinoma (NPC) is known to be associated with increased prevalence of carotid stenosis. The objectives of the study was to determine the prevalence of radiation-induced extracranial carotid stenosis, plaque, carotid intima thickness (CIMT) in NPC patients; to explore whether the stenosis is due to direct effect of radiation rather than general tendency to atherosclerosis. Methods: This was a cross-sectional study conducted in the University Malaya Medical Centre from July 2011 to February 2012. The study subjects consisted of 47 NPC patients who were treated with radiation, and 47 healthy control. The patients and control had carotid duplex ultrasound and transcranial Doppler (TCD). Results: The mean age of the patients was 55.1 years, the time lapse from radiation was 76.7 ± 95.3 months. Internal carotid artery (ICA) and common carotid artery (CCA) stenosis of ≥50% was seen in 17.0% of patients vs 2.1 % of controls (p = 0.031), with 61.7% of patients and 19.1% of controls having plaque in ICA and CCA (p=0.004). CIMT was increased in 70.2% of patients and 44.7% of controls (p =0.022). Both the patient group and control had similar rate of intracranial stenosis of 12.8% in TCD.
Conclusion: Extracranial internal carotid artery is the most common site of stenosis following radiotherapy in NPC. This suggests that local trauma from irradiation is the most important factor in predisposition to atherosclerosis following radiation therapy.
Melioidosis is an infectious disease caused by an aerobic, non-spore forming gram negative bacillus,
Burkholderia pseudomallei. It is known to be of high incidence in parts of rural South East Asia,
and in Northern Australia. Pneumonia is the commonest manifestation. We report here three cases of
neurological melioidosis from the registry of 169 cases of melioidosis in Bintulu Hospital, Sarawak,
East Malaysia, with a review of neurological melioidosis in the literature. The annual incidence of
melioidosis is estimated to be 8 per 100,000 populations in the Bintulu district. Neurological melioidosis
accounts for 1.8% of our melioidosis cases. A review of 76 cases of neurological melioidosis reported
in the literature inclusive of our 3 cases shows that localized brain or spinal inflammation or abscess
is the most common manifestation occurring in 80% of patients. Close to half (53%) have intra axial
abscess (brain or spinal cord), a quarter (27%) have extra axial lesions only (epidural or subdural
collection, osteomyelitis or scalp abscess), and another quarter (27%) have both intra and extra axial
lesions. Thus, B. pseudomallei appears to be unique among the bacterial central nervous system
infection to be able to affect the brain and its contiguous tissues, crossing the tissue plane particularly
resulting in osteomyelitis, scalp abscess and vice versa. Two thirds of the neurologicalmelioidosis
patients have only neurological disease with no evidence of disease elsewhere.
Background & Objective: Modulation of cortical excitability by low frequency repetitive transcranial
magnetic stimulation (rTMS) has demonstrated therapeutic use in epilepsy. This study aimed to evaluate
the efficacy of low-frequency rTMS on refractory epilepsy in a group of Malaysian subjects. Methods:
Nine patients with refractory epilepsy completed the study. All patients received 10 sessions of 1Hz
rTMS (1000 pulses per session) at 90% of resting motor threshold. Outcome measures included seizure
frequency, Symptom Checklist-90 (SCL-90), Beck Depression Inventory II (BDI II) and Quality of
Life in Epilepsy-31 (QOLIE-31). Responders were defined as having ≥ 50% seizure reduction. Results:
The mean age was 33.8 years (SD 11.7), with 4 male. Three patients had mesial temporal sclerosis
(MTS); 4 with focal cortical dysplasia (FCD) and two lesion-negative. Three patients achieved >50%
seizure reduction at 8 weeks post-treatment, with 2 of them had improvement in the number of IED.
All of the responders had FCD. The responders were younger (mean 24.7 vs. 38.3 years old), had
shorter duration of illness (mean 15.7 vs. 30.5 years) and had less frequent seizure frequency prior to
treatment (mean 5.5 vs. 10.8 attacks per week), as compared to the non-responders. Six patients had
improvement in BDI-II scores, two in QOLIE-31 and four in SCL-90 post treatment, irrespective of
seizure control. The mean scores in BDI-II improved significantly with treatment (p
Non-bacterial thrombotic endocarditis (NBTE) denotes the presence of sterile non-infective vegetation
on structurally normal, or subtly degenerate cardiac valves and is often associated with advanced
malignancies. In gynaecological cancer in particular, NBTE has been most commonly associated
with ovarian cancer.1,2 Here we report a rare but interesting case of NBTE in a patient with locally
advanced cervical adenocarcinoma.
Nipah virus was first discovered in 1999, after a severe outbreak of viral encephalitis among pig farm workers in Malaysia. The disease is thought to spread from Pteropus bats to pigs and then to humans following close contact. The reported mortality rate in this outbreak was 40%. The main necropsy finding in patients with Nipah virus encephalitis was disseminated microinfarction associated with vasculitis and direct neuronal involvement. Relapse of encephalitis was seen in 10% of those who survived the initial illness. Since that initial report, recurrent outbreaks of Nipah virus encephalitis have been seen in Bangladesh and West Bengal, India. These outbreaks occurred between January and May, with Pteropus giganteus as a reservoir of the virus. In Bangladesh, the virus probably spread directly from bats to humans-with human to human spread as another important mode of infection-and the mortality rate was 70%.
We report a patient with juvenile myoclonic epilepsy who subsequently developed temporal lobe epilepsy, which gradually became clinically dominant. Video telemetry revealed both myoclonic seizures and temporal lobe seizures. The temporal lobe seizures were accompanied by a focal recruiting rhythm with rapid generalisation on EEG, in which the ictal EEG pattern during the secondary generalised phase was morphologically similar to the ictal pattern during myoclonic seizures. The secondary generalised seizures of the focal epilepsy responded to sodium valproate, similar to the myoclonic epilepsy. In this rare case of coexistent Juvenile Myoclonic Epilepsy and Temporal lobe epilepsy, the possibility of focal epilepsy recruiting a generalised epileptic network was proposed and discussed.
A 13-year-old girl with a known diagnosis of systemic lupus erythematosus presented with seizures and psychosis. An electroencephalogram (EEG) revealed continuous, non-evolving periodic lateralized epileptiform discharges (PLEDs) in the left temporal region, which did not resolve with benzodiazepine. A magnetic resonance imaging (MRI) brain scan demonstrated a focal hyperintensity in the left medial temporal and left occipital lobes, left thalamus and bilateral cerebellar white matter, with evidence of vasculitis in the magnetic resonance angiography. Intravenous immunoglobulin was given because of failed steroid therapy, which resulted in a full resolution of clinical, EEG and MRI abnormalities. Lupus cerebritis should be considered as a possible aetiology in PLEDs, and immunoglobulin can be effective in neuropsychiatric lupus.
A 24-year-old woman presented with a 3.5-year history of paroxysmal dystonia that was precipitated by sudden movement, especially when she started to walk. It was characterised by shrugging of shoulders, flexion of the neck and thoracic spine, and stiffness of the right leg followed by falls. Each attack lasted for less than 5min. Inadequate sleep and stress were exacerbating factors. There was no similar family history. Physical examination and investigations were normal. The following manoeuvres that caused vestibular stimulation precipitated attacks: turning her head from side to side while standing still, sitting still on a rotating chair and an ice-water caloric test. She had partial responses to phenytoin and levodopa, and a good response to haloperidol. Vestibular stimulation as a precipitating factor in paroxysmal kinesigenic choreoathetosis has not been reported previously.
There are 50-100 million dengue infections each year, but dengue encephalitis is relatively
uncommon. The aetiology of neuronal injury is proposed to be due to direct viral neurotropism or
host immune response-mediated inflammation causing neuronal damage. We report a case of severe
dengue encephalitis, presenting during the acute viraemic phase of the disease. This was associated
with inflammation and haemorrhage of the internal medullary lamina of both thalami which, to our
knowledge, has not yet been reported in other infections of the central nervous system.
Background & Objective: Symptomatic sarcocystosis has been said to be rare until recent years, when there were reports of outbreaks of febrile myositis for travellers returning from the Malaysian island resorts. In 2012, an outbreak of Sarcocystis nesbitti infection involving 92 college students and staff occurred after returning from Pangkor Island, Malaysia. A few months after recovering from the febrile illness, some patients complained of hair loss. This study aimed to determine the prevalence, clinical features and outcome of this disorder.
Methods: All patients who became sick in the outbreak were asked whether they had the hair loss. For those who had, they were interviewed with standard questionnaires, examined and investigated. Patients were followed-up via an online survey 2 years later.
Results: Out of 89 patients who were ill, 19 patients (21.4%) complained of alopecia. The mean peak onset was 4 months after the initial illness. Eleven patients (57.9%) reported the hair fall of more than 100 per day. The other symptoms were itch 10 (52.6%), scaling 10 (52.6%), erythema 4 (21.1%), none had scarring. Eleven patients (57.8%) had positive antinuclear factor with high titre (speckled or nucleolar pattern). Two years after the event, 10 had complete or near complete spontaneous recovery, 1 had partial response and 1 had no improvement.
Conclusions: A delayed transient diffuse alopecia is seen in close to half of patients with Sarcocystis nesbittiinfection. This high frequency of positive ANF suggested an immune-mediated mechanism.

Background: Tuberculous disease of spine (spinal TB) is under-recognized in tuberculous (TB) meningitis.
The objective of the study was to evaluate the frequency, clinical and neuroimaging changes, and
outcome in the patients with spinal TB.
Methods: All the patients with spinal TB admitted in the two
largest tertiary hospitals in Kuala Lumpur from 2009 to 2017 were recruited, the clinical features were
documented, the magnetic resonance imaging (MRI) of the spine was performed. Clinical outcome was
assessed with Modified Rankin scale (MRS).
Results: Twenty two patients were recruited. This was
out of 70 TB meningitis patients (31.4%) seen over the same period. Eighteen (81.8%) patients had
concomitant TB meningitis. The clinical features consisted of systemic symptoms with fever (63.6%),
meningitis symptoms with altered sensorium (45.5%), myelopathy with paraparesis (36.4%). The
findings on spinal MRI were discitis (36.4%), spinal meningeal enhancement (31.8%), spinal cord
compression (31.8%), psoas abscess (27.3%), osteomyelitis (22.7%), and cord oedema (22.7%). All
except two patients (90.9%) had involvement in psoas muscle, bone or leptomeningeal enhancement,
features that can be used to differentiate from myelopathy that affect the parenchyma only, such as
demyelination. Unusual manifestations were syringomyelia and paradoxical manifestations seen in 3
patients each. The outcome were overall poor, with 68% having MRS 3 or more.
Conclusion: Spinal TB is common in TB meningitis. The outcome is overall poor. A heightened
awareness is crucial to enable early diagnosis and treatment.
Genetic predisposition to carbamazepine (CBZ)-induced Stevens-Johnson syndrome (SJS) and toxic
epidermal necrolysis (TEN) had been reported in several Southeast Asian populations, but not in
Myanmar. Previous studies had so far reported more than 70% of CBZ-induced SJS/TEN cases
positive for HLA-B*15:02 allele.1-4 Myanmar, as the second largest country in Southeast Asia with a
population of 54.5 million, has high HLA-B*15:02 carrier frequency in its general population (27.3-
49.1%).5,6 We investigated the association of HLA-B alleles and CBZ-induced SJS/TEN in Myanmar
population. HLA-B*15:02 was detected in 3/3 (100%) of cases and 6/53 (11.3%) of tolerant controls,
and HLA-B*15:02 is significantly associated with CBZ-SJS/TEN in Myanmar population (OR 51.2,
95% CI 2.36-1106.95, p=0.003). (Copied from article)
Background and Objective: There is a great challenge to establish a level 4 epilepsy care offering
complete evaluation for epilepsy surgery including invasive monitoring in a resource-limited country.
This study aimed to report the setup of a level 4 comprehensive epilepsy program in Malaysia and the
outcome of epilepsy surgery over the past 4 years.
Methods: This is a retrospective study analyzing
cases with intractable epilepsy in a comprehensive epilepsy program in University Malaya Medical
Center (UMMC), Kuala Lumpur, from January 2012 to August 2016.
Results: A total of 92 cases
had comprehensive epilepsy evaluation from January 2012 till August 2016. The mean age was 35.57
years old (range 15-59) and 54 (58.7%) were male. There were 17 cases having epilepsy surgery
after stage-1 evaluation. Eleven cases had mesial temporal sclerosis and 81% achieved Engel class
I surgical outcome. Six cases had lesionectomy and 60% had Engel class I outcome. A total of 16
surgeries were performed after stage-2 evaluation, including invasive EEG monitoring in 9 cases.
Among those with surgery performed more than 12 months from the time of data collection, 5/10
(50%) achieved Engel I outcome, whereas 2 (20%) had worthwhile improvement (Engel class III)
with 75% and 90% seizure reduction.
Conclusion: Level 4 epilepsy care has an important role and is possible with joint multidisciplinary
effort in a middle-income country like Malaysia despite resource limitation.
Background & Objective: Association between HLA-B*1502 and carbamazepine-induced StevenJohnson
syndrome/toxic epidermal necrolysis (CBZ-SJS/TEN) was reported in many Southeast Asian
populations but not in Indonesian. The purpose of this study was to evaluate the association between
HLA-B*1502 andCBZ-SJS/TEN in an Indonesian population.
Methods: Patients with history of
CBZ-SJS/TEN are recruited as cases and those who tolerated CBZ as controls. HLA-B typing was
performed.
Results: We recruited 14 cases with CBZ-SJS/TEN and 53 controls. Positive HLA-B*1502
was found in 8 (57.1%) cases and 14 (26.4%) controls (OR 3.7, 95% CI 1.09-12.61, p=0.035).
Conclusion: HLA-B*1502 is associated with CBZ-SJS/TEN patients in Indonesian.
Radiology-pathology correlation is essential for multidisciplinary collaboration in diagnosis and understanding the mechanism of CNS damage in infectious processes. The microscopic acute inflammatory processes are well established and are supplemented by a variety of less-invasive microbial and immunohistochemical investigations. Understanding the pathogenesis of pathogen spread and neuroinvasion, vascular and immune-mediated brain, and spinal cord damage are essential for interpreting radiological images.
