Objective: We aim to study the prevalence and predictive factors for hip displacement, in order to
justify a hip surveillance programme for children with cerebral palsy (CP) in Malaysia. Methods:
Children aged 2 to18 years old with CP were recruited from September 2013 till June 2014. The hip
joint migration percentage (MP) and acetabular index (AI) were measured on all hip radiographs.
The CP subtype was determined and gross motor function was classified according to the gross motor
function classification system (GMFCS).
Results: Seventy-five children were recruited. Fifty-five percent of them had marked hip displacement
with MP > 30% and 15% developed hip dislocation (MP=100%). Marked hip displacement occurred
as early as age of 2 years and most hip dislocations were detected by age of 10 years. The risk of
marked hip displacement was directly related to the GMFCS level, from none in GMFCS I to 75% in
GMFCS V. There was a moderate positive correlation between the initial AI and initial MP.
Conclusions: One in every two children with CP was at risk of hip displacement, with GMFCS level
and initial AI as significant predictive factors. We recommend a hip surveillance programme for
Malaysian children with CP, based on the child’s age and GMFCS level, with both MP and AI as
indicators for hip surveillance.

Objective: To evaluate the long-term efficacy, retention rate and tolerability of ketogenic diet treatment
(KD) for children with medically refractory epilepsies from a single tertiary centre in Malaysia.
Methods: Children who were treated with ketogenic diet since 2006 and had at least 2 years follow up
after initiation of the KD were evaluated retrospectively using intention-to-treat principle. Response is
defined at seizure reduction of > 50%. Efficacy was assessed as percentage of patients who had seizure
reduction by >50%, >90% and seizure freedom and retention rate was the proportion of patients who
remained on ketogenic diet. Result: A total of thirty children were included. The median duration of
treatment was 8 months (range: 7 days to 6 years). Retention rates at 3, 6, 12 and 24 months were 80%,
70%, 50% and 40% and responder rates were 70%, 63%, 47% and 37% respectively. The common
adverse effects were constipation (43%), hunger (23%), excessive weight gain or loss (20%), vomiting
(10%), hyperuricaemia(30%), hypocalcaemia (20%) and renal calculi (13%). The common reasons
for stopping were because the diet was too restrictive (33%), infrequent seizure or seizure freedom
(23%), not effective (17%) but none was due to the adverse effects.
Conclusion: Ketogenic diet treatment is effective and well-tolerated by Malaysian children in general.

Background & Objective: SCN1A gene which encodes for sodium channel alpha 1 subunit has been
found to be the most common mutated gene in patients with epilepsy. This study aims to characterize the
SCN1A mutations as well as to describe genotype and phenotype association in children with SCN1Arelated
infantile-onset epileptic encephalopathies in Malaysia. Methods: Children with infantile-onset
epileptic encephalopathy mostly suspected to have Dravet syndrome who had mutational analysis for
SCN1A gene from hospitals all over Malaysia were included in the study. Their epilepsy syndrome
diagnosis was classified into severe myoclonic epilepsy in infancy and its variants. Polymerase chain
reaction and bidirectional sequencing were used to identify SCN1A mutations. Results: A total of 38
children with heterozygous mutations were analysed, 22 (57.9%) of which were novel mutations.
Truncated mutations were the most common mutation type (19, 50%). Other mutation types were
missense mutations (14, 36.8%), splice site mutations (4, 10.5%) and in-frame deletion (1, 2.6%). The
mean age of seizure onset was 4.7 months. Seizure following vaccination was observed in 26.3% of
the children. All of them had drug resistant epilepsy. There was no significant association between
the type of mutation with the syndromic diagnosis, age of seizure onset, tendency of the seizures to
cluster or having status epilepticus, mean age when developmental delay was observed and response
to various antiepileptic drugs.
Conclusion: This study expands the spectrum of SCN1A mutations and proves the importance of
SCN1A gene testing in diagnosing infantile-onset epileptic encephalopathies patients. Although, our
study does not support any clinically meaningful genotype-phenotype association for SCN1A-related
infantile-onset epileptic encephalopathies, the clinical characteristics of our cohort are similar to those
that have been described in previous studies.

Introduction: Awareness for paediatric palliative care has
resulted in the impetus for paediatrician-led palliative care
services across Malaysia. However, there is paucity of local
data on patients receiving hospital-based paediatric
palliative care. We aim to review the clinical spectrum of
patients referred to these services.
Methods: An observational study of children aged between
0-18 years receiving palliative care at 13 hospitals between
1st January and 31st December 2014 was carried out.
Results: There were 315 patients analysed, 90 (28.6%) and
46 (14.6%) were neonates and adolescents respectively. The
main ICD-10 diagnostic categories for all patients were
identified to be ‘Congenital malformations, deformations
and chromosomal abnormalities’ 117 (37.1%), ‘Diseases of
nervous system’ 76 (24.1%) and ‘Neoplasms’ 60 (19.0%). At
referral 156 (50%) patients had holistic needs assessments.
Patients with ‘Diseases of nervous system’ were assessed
to have significantly more physical needs than the other two
diagnostic categories. Majority of patients who knew of their
diagnosis and prognosis were those with malignancy. Over
a fifth of referrals were at their terminal admission. Of 144
who died, 111 (77.1%) had advanced care plans. There was
bereavement follow-up in 98 (68.1%) patients.
Conclusion: Patients referred for palliative care have varied
diagnoses and needs. To ensure all paediatricians are
competent to deliver quality care to all children, further
education and training initiatives is imperative.
