Sixteen percent of ALL survivors had VIPN. VIPN should be increasingly recognised as a late effect of chemotherapy, as it significantly affects physical and social function quality of life.

Parkinsonism as a neurologic manifestation of dengue infection is rare with only 1 reported case in an adult patient. We report a case of a 6-year-old child with self-limiting post-dengue encephalopathy and Parkinsonism. This is the first reported pediatric case of post-dengue Parkinsonism and expands the neurologic manifestations associated with dengue infection in children. Clinicians should consider the possibility of post-dengue Parkinsonism in children with a history of pyrexia from endemic areas of dengue.

The quality of evidence for the comparisons of oral chloral hydrate against several other methods of sedation was very variable. Oral chloral hydrate appears to have a lower sedation failure rate when compared with oral promethazine for children undergoing paediatric neurodiagnostic procedures. The sedation failure was similar for other comparisons such as oral dexmedetomidine, oral hydroxyzine hydrochloride, and oral midazolam. When compared with intravenous pentobarbital and music therapy, oral chloral hydrate had a higher sedation failure rate. However, it must be noted that the evidence for the outcomes for the comparisons of oral chloral hydrate against intravenous pentobarbital and music therapy was of very low to low quality, therefore the corresponding findings should be interpreted with caution.Further research should determine the effects of oral chloral hydrate on major clinical outcomes such as successful completion of procedures, requirements for additional sedative agent, and degree of sedation measured using validated scales, which were rarely assessed in the studies included in this review. The safety profile of chloral hydrate should be studied further, especially the risk of major adverse effects such as bradycardia, hypotension, and oxygen desaturation.

The aim of this study is to evaluate the psychometric properties of the translated Malay language version of TZO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire in preschool children. Preterm children and term children aged between two and five years were enrolled into the study. The Malay language version of TAPQOL and a set of questions regarding the child's health status were answered by the caregivers. The internal consistency, Spearman's correlation coefficients and principal component analysis (PCA) with Varimax rotation and Mann-Whitney U test for group comparison were employed to evaluate the psychometric properties of this instrument. A total of 258 children (120 preterm children and 138 term children) were recruited to this study with a response rate of 94%. All (sub)domains except one had Cronbach's α coefficients of more than .7. The Spearman's correlation coefficients between 12 subdomains were generally low. PCA supported the structural unidimensionality of the items in the instrument. Preterm children had lower quality of life scores than that of term children. Malay version of TAPQOL has multidimensional construct. It is a reliable and valid instrument for preschool children, with almost similar psychometric properties to the original version.

Succinic semialdehyde dehydrogenase deficiency is a rare autosomal recessive disorder affecting catabolism of the neurotransmitter gamma-aminobutyric acid (GABA), with a wide range of clinical phenotype. We report a Malaysian Chinese boy with a severe early onset phenotype due to a previously unreported mutation. Urine organic acid chromatogram revealed elevated 4-hydroxybutyric acid. Magnetic resonance imaging (MRI) of the brain demonstrated cerebral atrophy with atypical putaminal involvement. Molecular genetic analysis showed a novel homozygous 3-bp deletion at the ALDH5A1 gene c.1501_1503del (p.Glu501del). Both parents were confirmed to be heterozygotes for the p.Glu501del mutation. The clinical course was complicated by the development of subdural hemorrhage probably as a result of rocking the child to sleep for erratic sleep-wake cycles. This case illustrates the need to recognize that trivial or unintentional shaking of such children, especially in the presence of cerebral atrophy, can lead to subdural hemorrhage.
