    Data are presented for 2382 children investigated for fever in a Malaysian hospital between 1984 and 1987 when Widal tests and blood cultures were a routine part of every fever screen. There were 145 children who were culture positive (TYP-CP) for Salmonella typhi, while 166 were culture negative but were diagnosed as having typhoid (TYP-CN). Analyses of the sensitivity and specificity of combinations of initial Widal titres in predicting a positive S. typhi culture in a febrile child (culture positive vs the rest) showed the best model to be an O- and/or H-titre of > or = 1 in 40 (sensitivity 89%; specificity 89%). While the negative predictive value of the model was high (99.2%) the positive predictive value remained below 50% even for very high titres of O and H (> 1 in 640), at which point the specificity was 98.5%, supporting the clinical view that a high proportion of the TYP-CN patients really were typhoid but were missed by culture. The TYP-CN patients showed a very similar clinical and age profile to TYP-CP patients. The length of history of fever did not affect the initial Widal titre in culture positive cases. The Widal test in children remains a sensitive and specific 'fever screen' for typhoid although it will not identify all cases. In children, lower cut-off points for O- and H-titres should be used than are generally recommended.

    OBJECTIVE: To describe the clinical features, management and outcome of children with cyclic vomiting syndrome (CVS) from South-East Asia.

    METHODOLOGY: Retrospective review of all children who fulfilled the diagnostic criteria of CVS and who were seen at Department of Paediatrics, University of Malaya Medical Centre, Kuala Lumpur and Paediatric Unit, Penang Hospital, Penang, Malaysia from 1987 to 1997.

    RESULTS: Eight children with CVS were seen at the two units during the study period, five girls and three boys. All had cyclical, self-limited episodes of nausea and vomiting with symptom-free intervals. The mean age of onset was 5.9 years. The clinical features were similar to other series described in the literature. Only two of the eight children were described as 'perfectionist'. Two children identified stress as precipitating factors. Therapy to reduce the number of emeses during acute attacks and to prevent subsequent attacks had been ineffective.

    CONCLUSION: There are similarities and differences in CVS from South-East Asian children as compared to those described in the literature.

    OBJECTIVE: To study the clinical features of non-typhoid Salmonella gastroenteritis and the incidence, risk factors and outcome of invasive complications in urban Malaysian children. To describe the serotypes of Salmonella species isolated and the pattern of antibiotic susceptibility.

    METHODOLOGY: Retrospective review of a group of 131 children with non-typhoid Salmonella gastroenteritis seen at the University Hospital, Kuala Lumpur, Malaysia from January 1994 to December 1996.

    RESULTS: Sixty-seven percent were infants below one year of age. Fever and vomiting were seen in nearly half of children. Seven children (5.3%) had invasive complications: 5 bacteraemia and 2 meningitis. Age below 6 months, fever > 38.0 degrees C, and dehydration on admission were significantly associated with invasive complications. The commonest serotypes isolated were S. enteritidis, S. paratyphi B, and S. bovis-morbificans. A total of 94-100% of isolates were susceptible to commonly prescribed antibiotics.

    CONCLUSIONS: Children with Salmonella gastroenteritis below 6 months of age who are febrile and dehydrated should be treated empirically with antibiotics until the result of blood culture is available.

    OBJECTIVES: To compare the neurobehavioural outcome of children aged 6-12 years with severe closed head injury [sCHI] (coma > 24 h), mild-to-moderate head injury [mCHI] (coma < 6 h) and orthopaedic controls.

    METHODS: Twenty-nine children in each group, matched for age, sex and ethnicity, were assessed using the Glasgow outcome Scale (GOS), Weschler Intelligence Scale for Children (WISC-III), Movement Assessment Battery for Children (Movement ABC), Wide Range Assessment of Learning and Memory (WRAML) and a standardised neurological examination 6 months post-injury. Parental reporting of pre- and post-injury behaviour was documented using the Child Behaviour Checklist (CBCL).

    RESULTS: Seven (24.1%) children with sCHI and three (10.3%) orthopaedic controls had residual motor deficits. Three (10.3%) children with sCHI and none in the other groups faced problems with independent ambulation. Twenty-seven (93.1%) of those with sCHI and all children in the other groups had GOS scores of good recovery or moderate disability. Twenty-two (81.5%) sCHI, five (18.5%) mCHI and one (3.7%) orthopaedic control reported a deterioration in school performance. MANOVAS identified a significant injury group effect for performance skills (P = 0.007), verbal skills (P = 0.002), memory and learning (P = 0.001) and motor skills (P = 0.001). Repeated measures ANOVA for pre- and post-injury CBCL scores showed significant differences related to somatic complaints (P = 0.004), problems of socialising (P = 0.003), delinquency (P = 0.004), aggressiveness (P = 0.010), thought (P < 0.001) and attention (P < 0.001). Post-hoc univariate analysis showed the significant differences were between that of the sCHI children and the other two groups.

    CONCLUSION: Although most sCHI children seemed to have made good physical recovery, there were cognitive, motor, memory and learning difficulties and behavioural problems concomitant with a deterioration in school performance compared with those with lesser or no head injury. This highlights the need for better integrated rehabilitation services to enable a gradual return into mainstream school.

    This prospective study was performed to quantify glucose-6-phosphate dehydrogenase (G6PD) enzyme activity in deficient males and female heterozygotes. The methods used in the study were the fluorescent spot test, G6PD enzyme electrophoresis on cellulose acetate and quantitative assays. Forty-seven children who had been detected as spot screen deficient at birth were rescreened. Their first degree relatives were also included in the study. The mean enzyme activity of deficient males was 0.74 iu/g Hb (s.d. +/- 0.8), of female heterozygotes was 6.5 iu/g Hb (s.d. +/- 3.2) and of normal males was 12.1 iu/g Hb (s.d. +/- 3.5). The mean activity in deficient males was 6.1% of normal males. Most (35 of 47) of these fell into class 2 in Beutler's classification of G6PD variants. This indicates a population which may be susceptible to favism. Female heterozygotes had an intermediate enzyme activity with a wide scatter. Using a cut off point of enzyme activity of below 9.0 iu/g Hb gave sensitivity and specificity of 87% and 84% in detecting female heterozygotes. This group could be defined more accurately by combining quantitative assays with family studies.

    OBJECTIVE: The nation-wide surveillance for acute flaccid paralysis (AFP) was implemented in Malaysia in 1995 and further intensified in 1996 as part of the World Health Organization's (WHO) certification process for polio eradication in the Western Pacific Region. Clinical data on AFP cases during a 5-year surveillance period from 1997 to 2001 were compiled and analysed.

    RESULTS: Based on 517 cases of AFP reported during this 5-year period, the overall rate of AFP was 1.2 per 100 000 children below 15 years old. The major clinical diagnosis associated with AFP were Guillain-Barre syndrome (30.2%), central nervous system infection (16.2%), transverse myelitis (10.6%) non-polio enterovirus infection (6.2%), and hypokalaemic paralysis (5.2%). This unusual pattern with an excess of CNS infection and non-polio enterovirus infection was attributed to the outbreak of enterovirus 71 infection nation-wide in 1997. According to the WHO virological classification, there was no case of poliomyelitis due to wild poliovirus. Three cases were 'polio compatible', there were no cases of vaccine-associated paralytic polio (VAPP), while 62 cases (12.0%) were merely classified as 'non-polio AFP'.

    CONCLUSION: Overall, these data suggest the absence of circulation of wild poliovirus in Malaysia from 1997 to 2001. The pattern of AFP in this study is different from other published reports.

    The coronavirus disease 2019 (COVID-19) cases was on an increasing trend, including in Malaysia. The Malaysian Ministry of Health had implemented a range of measures, such as the use of masks and social distancing, to reduce the risk of transmission. Traditionally, newborns are evaluated for neonatal jaundice using visual assessment, a capillary heel prick and serum bilirubin (SB) sampling in primary health-care clinics. This approach requires the physical presence of both parents and their newborns in the primary health-care clinics, causing crowding and increasing the risk of COVID-19 infections. To alleviate crowding, we implemented the transcutaneous bilirubin drive-through (DT) service, which is an established, non-invasive, painless and rapid method to determine the bilirubin levels. Throughout the screening, both parents and baby will be confined to their car. A total of 1842 babies were screened in our DT setting from April to July 2020. Of the total babies, 298 (16.1%) required venesection for SB measurement and 85 required admission for phototherapy. None with severe jaundice were missed since the implementation of this service. The average test duration per neonate was less than 5 min, while conventional venous bilirubin laboratory testing required an average of 1.5 h per neonate. The cost of the SB laboratory test and consumables was approximately USD 5 per test, with an estimated cost savings of USD 7720. DT screening may be introduced in health-care settings to reduce crowding and eliminate the need of painful blood sampling in newborns.

    AIM: Inborn errors of immunity (IEI) comprise a heterogeneous group of disorders of the immune system, most of which are curable by haematopoietic stem cell transplantation (HSCT). We present a 25-year audit of HSCT for IEI at a tertiary-level academic hospital in Malaysia.

    METHODS: Review of medical records of all cases of IEI who underwent HSCT between January 1993 and December 2018 at our centre. Diagnoses, complications, HSCT protocols and outcome data were studied.

    RESULTS: There were 20 patients (19 boys) with a median age at diagnosis of 11 months (range: 2 months to 12 years). Eleven of 19 (58%) had malnutrition at presentation. Donor sources were variable: 13 (65%) matched sibling donor (MSD), 4 (20%) human leukocyte antigen-haploidentical donor (HD) and 3 (15%) matched unrelated donor (MUD). Conditioning regimens were physician-dependent and adapted to each patient's clinical status. Grades III-IV acute graft-versus-host disease occurred in two of three cases who received MUD grafts, 50% in those who received HD, and 8% in the MSD group. Transplant-related mortality at day +100 was 5%. With a median follow-up of 7.5 years, 18 (90%) patients are alive and free of infections.

    CONCLUSION: Outcome of HSCT for IEI in our centre is comparable with international reports. HSCT results using HD and MUD grafts are also good despite challenges from acute graft-versus-host disease, providing a feasible alternative for patients without matched donors.

    AIM: A collaborative study was conducted between two Southeast Asian university hospitals to compare the nutritional intervention and growth outcomes and evaluate the extent of post-natal growth faltering (PNGF) among very low birthweight (VLBW) infants.

    METHODS: Data of all infants admitted during the 2011-2012 period to the two hospitals at Singapore (SG) and Malaysia (MY) were pooled and analysed.

    RESULTS: Of the 236 infants, SG infants received lower total protein and energy intake than MY infants (2.69 vs. 3.54 g/kg/day and 92.4 vs. 128.9 kcal/kg/day respectively; P -2 SDS (55 vs. 16%; P = 0.001). The greater use of a diuretic in SG to treat haemodynamically significant patent ductus arteriosus (hsPDA) may have contributed to the higher PNGF rate. Mean growth velocity of at least 15 g/kg/day was attained by VLBW infants only from Day 14 and by ELBW infants only from Day 28 post-natally. Overall, severe PNGF rates (z-score change >-2 SDS at 36 weeks' corrected age) were 28.8 and 36.5% for VLBW and ELBW infants, respectively.

    CONCLUSIONS: Being very preterm, ELBW with hsPDA and receiving insufficient protein and energy were risk factors for severe PNGF. Increasing protein and energy content, augmenting fortification of breast milk and concentrating feed volumes, especially if there is an hsPDA, may curb severe PNGF among these infants.

    AIM: Bed sharing is defined as a newborn sleeping in the same bed with an adult. Bed sharing may put the newborn at risk of suffocation due to accidental smothering.

    METHODS: This was a quasi-experimental study conducted in a tertiary referral hospital. Healthy post-delivery Malaysian mothers were randomly selected and enrolled into the control or the intervention group. On the day of discharge, mothers in the intervention group were interviewed face-to-face in the post-natal ward on their plans for sleeping arrangement with their newborn. After the interview, mothers were advised not to bed share with their newborn and were given an educational leaflet on safe sleeping practices. One week after discharge, mothers in both groups were interviewed over the telephone regarding their actual sleeping arrangements with their newborn using the same questionnaire. Logistic regression was performed to determine factors associated with reduced bed sharing.

    RESULTS: A total of 94 mothers and 95 mothers were recruited to the control and intervention group, respectively. The baseline bed-sharing prevalence was similar between groups: 60.6% in the control group and 61.1% in the interventional group. The proportion of mothers who bed shared with their newborn reduced from 61.1 to 37.9% after the intervention (P

    AIM: The optimal placement of the endotracheal tube (ETT) in ventilated infants is essential, but birthweight may be not the best parameter to predict it. The aim of this study was a direct comparison of shoulder-umbilical length (experimental group) versus birthweight (control group) as predictor of optimal ETT placement in Malaysian ventilated infants.

    METHODS: All infants requiring ventilation in the neonatal intensive care unit of a tertiary hospital in Malaysia during the 4-month study period were eligible to enter this randomised controlled trial. All participants were randomised into two groups: experimental and control group. The main outcome measure was malposition of the ETT (requiring adjustment), as seen on the chest X-ray performed within 1 h after intubation. Tube placement was assessed by two neonatologists, blinded to the allocation.

    RESULTS: One hundred and ten infants were randomised, 55 in each group. The ETT was malpositioned in 13 of 55 infants (23%) for the experimental group and 22 of 55 infants (40%) in the control group (P = 0.06).

    CONCLUSION: In the experimental group, fewer infants showed a need for tube adjustment than in the control group. While a larger study may be necessary to show statistical significance, the difference shown in this study may be large enough to be of clinical significance.

    AIM: We aimed to ascertain the efficacy and feasibility of exclusive enteral nutrition (EEN) as an induction and re-induction therapy in Asian children with Crohn's disease (CD).

    METHODS: All children diagnosed with CD between 1995 and 2019 were reviewed. Response to induction was compared between EEN and standard immunosuppression (IS) using Paediatric Crohn's Disease Activity Index, growth failure, perianal disease and extra-intestinal manifestations. Two study groups were analysed: (i) primary induction and (ii) re-induction for relapses.

    RESULTS: Twenty-nine children (mean age (± standard deviation) at diagnosis 9.4 ± 8.5 years old, ileo-colonic 35%, non-stricturing 79%) were studied. At primary induction (group 1; n = 18), no difference was observed in remission rates (9/13 vs. 5/5; P = 0.278), efficacy for improving growth failure (6/8 vs. 0/1; P > 0.999), perianal disease (4/6 vs. 0/2; P > 0.999) and extra-intestinal manifestations (2/2 vs. 0/0; P > 0.999) with EEN or standard IS. Group 2 (n = 38 relapses), no difference was observed in remission rates (16/19 vs. 15/19, P > 0.999), growth failure (0/7 vs. 4/14; P = 0.328), perianal disease (1/10 vs. 7/7; P > 0.999) and extra-intestinal manifestations (0/0 vs. 1/1; P > 0.999) with EEN or standard IS. Both treatment modalities were equally effective as re-induction in relapses in patients previously treated with EEN (P = 0.191).

    CONCLUSION: As compared to standard IS, EEN was equally effective in primary induction and re-induction for relapse in Asian children with CD and can be repeatedly used for recurrent relapses.

    AIM: The aim of this study is to describe epidemiology, clinical features, laboratory data and severity of respiratory syncytial virus (RSV) acute lower respiratory infection (ALRI) in Malaysian children and to determine risk factors associated with prolonged hospital stay, paediatric intensive care unit (PICU) admission and mortality.

    METHODS: Retrospective data on demographics, clinical presentation, outcomes and laboratory findings of 450 children admitted into Tuanku Jaafar Hospital in Seremban, Malaysia from 2008 to 2013 with documented diagnosis of RSV ALRI were collected and analysed.

    RESULTS: Most admissions were children below 2 years old (85.8%; 386/450). Commonest symptoms were fever (84.2%; 379/450), cough (97.8%; 440/450) and rhinorrhea (83.6%; 376/450). The median age among febrile patients (n = 379) was 9.0 months with interquartile range (IQR) of 4.0-19.0 months whereas the median age among those who were apyrexial (n = 71) was 2 months with IQR of 1-6 months (P-value <0.001). 15.3% (69/450) needed intensive care and 1.6% (7/450) died. Young age, history of prematurity, chronic comorbidity and thrombocytosis were significantly associated with prolonged hospital stay, PICU admission and mortality.

    CONCLUSIONS: Infants less than 6 months old with RSV ALRI tend to be afebrile at presentation. Younger age, history of prematurity, chronic comorbidity and thrombocytosis are predictors of severe RSV ALRI among Malaysian children. Case fatality rate for Malaysian children below 5 years of age with RSV ALRI in our centre is higher than what is seen in developed countries, suggesting that there is room for improvement.

    AIM: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a recognised cause of severe neonatal hyperbilirubinaemia, and identifying which infants are at risk could optimise care and resources. In this study, we determined if G6PD enzyme activity (EA) and certain gene variants were associated with neonatal hyperbilirubinaemia requiring phototherapy during the first week after birth.
    METHODS: Newborn infants with G6PD deficiency and a group with normal results obtained by the fluorescent spot test were selected for analyses of G6PD EA and the 10 commonly encountered G6PD mutations in this region, relating these with whether the infants required phototherapy before discharge from the hospital in the first week.
    RESULTS: A total of 222 infants with mean gestation and birth weight of 38.3 ± 1.8 weeks and 3.02 ± 0.48 kg, respectively, were enrolled. Of these, n = 121 were deficient with EA ≤6.76 U/g Hb, and approximately half (43%) received phototherapy in the first week after birth. The mean EA level was 3.7 U/g Hb. The EA had good accuracy in predicting phototherapy use, with area under the receiver-operating-characteristic curve of 0.81 ± 0.05. Infants on phototherapy more commonly displayed World Health Organization Class II mutations (<10% residual EA). Logistic regression analysis showed that deficiency in EA and mutation at c.1388G>A (adjusted odds ratio, 1.5 and 5.7; 95% confidence interval: 1.31-1.76 and 1.30-25.0, respectively) were independent risk factors for phototherapy.
    CONCLUSION: Low G6PD EA (<6.76 U/g Hb) and the G6PD gene variant, c.1388G>A, are risk factors for the need of phototherapy in newborn infants during the first week after birth.
