MyJurnal

Developmental disabilities in young children are common, and the prevalence is estimated as high as 0.1-1.75% in the children population for each disabilities. With increasing awareness and health expectation, more children with Developmental disabilities are presenting to health care professionals, and at earlier age. Literatures also suggested the importance of early intervention programme in determining the outcome of this group of children. Therefore, it is vital for health professionals who have direct contact with young children are competent in detecting children with possible Developmental disabilities, and have the basic knowledge about some of the common disorders in order to discuss the issues with the parents. It is also important to work with the various resources available in the local community, such as non-governmental organisations for children with special needs, schools offering special education programmes and inclusive classes, and the allied health who provide cares to this group of young children and their family. A lot of information are also available online, and may be offered to help parents gaining more understanding regarding these Developmental disabilities.

Introduction More school children were referred for learning difficutly (LD), especially after the introduction of LINUS sccreening programme by Ministry of Education Malaysia.
Aims To study the clinical diagnosis and non-verbal ability of primary-one school children with LD after paediatric assessment, as well as associated behavioural issues and socio-economincal background.
Methods Assessment findings by Paediatricians and Naglieri Non-Verbal Ability Test®(NNAT®) results of all primary-one school children referred in year 2010 with LD were studied retrospectively.
Results Ninety-three children were included (62.4% male), and 72.0% of them failed the LINUS screening programme. The commonest diagnoses were Borderline Intellectual Disability (ID, 37.6%) and Mild ID (19.4%). Other diagnoses included Attention Deficit Hyperactive Disorder (ADHD, 11.8%), Specific Learning Disability (SLD, 10.8%), Autistic Spectrum Disorder (n = 5) and Severe Language Disorder (n = 3). Mean NNAT scores were 84.6 ± 11.8 (n = 85), of which 9.4% children scored less than 70 (

Introduction Special Olympics (SO) Inc. is an organization for people with intellectual disability (ID) to actively engaging in Olympic-type sport and participating in competition. Special Olympic Inc. provides Healthy Athletes Programme (HAP®) in screening and providing health education to Special Olympic Athletes. Objective To study the body mass index (BMI), blood pressure (BP), visual acuity and hearing status of children and young adult with ID in Special Olympics Sarawak. Methods Health data were collected by trained health professionals under HAP®held in conjunction with Special Olympics Sarawak State Games on 17th and 18th April 2010 in Sibu. Health data collected were athletes' weight, BMI, BP, ear canal screen and hearing status (oto-acoustic emission, pure tone audiometry), as well as eye health and visual acuity, using guidelines set by HAP®. Results 195 athletes attended the State Games in 2010 of which 138 were screened. Significant number of athletes was considered overweight / obese (31.5% for children and 36.9% for adult). More than 20% of the adult athletes were hypertensive or at risk of hypertension. Sixteen percent of the adult athletes had hearing loss. More than half of the adult and children athletes never had eye checks, and a significant numbers of them had abnormal eye tests results. Conclusions Health screening conducted during the HAP® is a useful screening program in this population. Health data collected can bring awareness to athletes and their family, and corrective measures in hearing and visual impairment can be taken immediately.

Introduction Children with cerebral palsy (CP) are often prescribed Rehabilitation and Seating Systems (RSS) to assist in daily activities, posture improvement and prevention of muscular-skeletal complications. In Sarawak, a special project to produce RSS was started under a partnership of a Japanese physiotherapist, health department and the community using local material.Aim To document the RSS project and to determine usefulness and costaffordability of these systems for cerebral palsy children and their families.
Methods The details of RSS manufactured were retrieved from the clinic notes and secretary file. Parents of children who received the seating systems between July 2004 and September 2008 were invited to complete a 5-point Global Parental Perception Questionnaire (GPPQ) between December 2008 and January 2009.
Results 277 RSS were manufactured between July 2004 and February 2011 (which included modified wheel chair, wooden chair, corner chair, buggy chair and standing frame), and used by children all over Sarawak. Parents of 73 children who used the seating systems completed the 5-points GPPQ. Ten families required full sponsorship. Children spent more time sitting up and brought outdoor more often after the systems became available. Majority of parents reported positive experience in their children with sitting ability, smiles, interaction with people, learning skills and easiness of doing physiotherapy. No change was noted with passing of motion drooling / oral secretion. Most parents agreed that the cost was affordable and worth paying.
Conclusions A community based initiative to manufacture RSS by using locally available material and skill, at affordable price for the parents was feasible and useful for the family/children with CP.
Topical Review: Mind Your Language-Translation Matters (A Narrative Review of Translation Challenges)

Kiing JS, Rajgor D, Toh TH

J Pediatr Psychol, 2016 11;41(10):1110-1119.
PMID: 27189689

OBJECTIVE: Translation of developmental-behavioral screening tools for use worldwide can be daunting. We summarize issues in translating these tools. METHODS: Instead of a theoretical framework of "equivalence" by Pena and International Test Commission guidelines, we decided upon a practical approach used by the American Association of Orthopedic Surgeons (AAOS). We derived vignettes from the Parents' Evaluation of Developmental Status manual and published literature and mapped them to AAOS. RESULTS: We found that a systematic approach to planning and translating developmental-behavioral screeners is essential to ensure "equivalence" and encourage wide consultation with experts. CONCLUSION: Our narrative highlights how translations can result in many challenges and needed revisions to achieve "equivalence" such that the items remain consistent, valid, and meaningful in the new language for use in different cultures. Information sharing across the community of researchers is encouraged. This narrative may be helpful to novice researchers.
Spontaneous neonatal scrotal haematoma: an early manifestation of severe haemophilia

Lee JS, Chieng CH, Martin M, Toh TH

BMJ Case Rep, 2021 Apr 28;14(4).
PMID: 33910804 DOI: 10.1136/bcr-2020-241482

We report a term newborn who presented on day 3 of life with unilateral, tender scrotal swelling with skin discolouration, which was subsequently diagnosed as haemophilia A at about 6 months of age. He received intramuscular vitamin K and hepatitis B vaccine at birth uneventfully. The scrotal swelling was treated as an infected hydrocoele, considering the absence of a family history of bleeding disorder and other risks of bleeding tendency, as well as the ultrasonographic features. He also had congenital pneumonia requiring venepuncture, non-invasive oxygen supplementation and intravenous antibiotics, without any complication. The swelling slowly improved over 2 months. He later developed post-trial vaccine injection haematoma at 4 months of age, and multiple non-traumatic bruises when he was 6 months old, leading to the diagnosis. This case demonstrates an uncommon, but a possible, early manifestation of haemophilia A at birth with a unilateral scrotal haematoma.

Belaga District, in the heart of Borneo, is probably the most remote district in Sarawak. Although Belaga town is now accessible by land (50% are timber camp unsealed road) from Bintulu, the journey takes 5 hours and transport cost is high. Accessibility to Belaga by river is also subject to weather conditions and the town often gets cut off during the dry season and also during the wet season. All these pose immense challenges to the delivery of health care services to the people of Belaga and greatly reduce their accessibility to even basic health services. Access to specialist services is even more challenging as it is only available in Sibu and Bintulu; and visiting clinics in Belaga are infrequent due to the shortage of specialists and difficult transport.

Postintravenous immunoglobulin stroke in a toddler with Down syndrome: a diagnostic challenge

Toh TH, Siew EC, Chieng CH, Mohd Ismail HI

BMJ Case Rep, 2020 May 18;13(5).
PMID: 32430349 DOI: 10.1136/bcr-2019-233149

Children with Down syndrome have a higher risk of stroke. Similarly, intravenous immunoglobulin (IV Ig) is also known to cause a stroke. We reported a 3-year-old boy with Down syndrome who presented with severe pneumonia and received IV Ig. He developed right hemiparesis 60 hours after the infusion. Blood investigations, echocardiography and carotid Doppler did not suggest vasculitis, thrombophilia or extracranial dissection. Brain computerised tomography (CT) showed acute left frontal and parietal infarcts. Initial magnetic resonance angiography (MRA) of cerebral vessels showed short segment attenuations of both proximal middle cerebral arteries and reduction in the calibre of bilateral supraclinoid internal carotid arteries. The boy was treated with enoxaparin and aspirin. He only had partial recovery of the hemiparesis on follow-up. A repeat MRA 13 months later showed parenchymal collateral vessels suggestive of moyamoya disease. We recommend imaging the cerebral vessels in children with a high risk of moyamoya before giving IV Ig.

Toh TH, Tan VW, Lau PS, Kiyu A

J Autism Dev Disord, 2018 01;48(1):28-35.
PMID: 28866856 DOI: 10.1007/s10803-017-3287-x

This study determined the accuracy of Modified Checklist for Autism in Toddlers (M-CHAT) in detecting toddlers with autism spectrum disorder (ASD) and other developmental disorders (DD) in community mother and child health clinics. We analysed 19,297 eligible toddlers (15-36 months) who had M-CHAT performed in 2006-2011. Overall sensitivities for detecting ASD and all DD were poor but better in the 21 to <27 months and 27-36-month age cohorts (54.5-64.3%). Although positive predictive value (PPV) was poor for ASD, especially the younger cohort, positive M-CHAT helped in detecting all DD (PPV = 81.6%). This suggested M-CHAT for screening ASD was accurate for older cohorts (>21 months) and a useful screening tool for all DD.
Fulltext Biochemically normal adrenal pheochromocytoma following extensive central necrosis in a child with von Hippel-Lindau (VHL) gene mutation

Ng BW, Wong JS, Toh TH

BMJ Case Rep, 2021 Dec 22;14(12).
PMID: 34937752 DOI: 10.1136/bcr-2021-245154

Pheochromocytomas are rare in children. The diagnosis is usually established from a raised urinary or plasma catecholamine or their metabolites. We present a girl aged 11 years who manifested with a hypertensive crisis secondary to an adrenal tumour but with unexpectedly normal urinary metanephrine and catecholamine results. She improved spontaneously following the crisis and underwent surgery later. The histopathological study confirmed a pheochromocytoma with large central necrosis. Her genetic screening reported a pathogenic von Hippel-Lindau gene mutation. Surveillance scan postsurgery detected no other tumours. Following the catecholamine crisis, an acute infarct occurred, resulting in extensive tumour necrosis and subsequent rapid remission of symptoms and paradoxically normal biochemical markers. Although not unheard of in adults, we believe this is the first reported case of an extensive spontaneous necrosis resulting in a biochemically normal pheochromocytoma in a child.

Toh TH, Lim BC, Bujang MAB, Haniff J, Wong SC, Abdullah MR

Pediatr Int, 2017 Aug;59(8):861-868.
PMID: 28510345 DOI: 10.1111/ped.13325

BACKGROUND: We examined the parental perception and accuracy of the Mandarin translation of the Parents' Evaluation of Developmental Status, a screening questionnaire for parent concerns about children's various developmental skills.
METHODS: The questionnaire was translated into Mandarin. Upon enrollment, caregivers completed the Mandarin PEDS and answered four questions about its acceptability and usefulness, and its ease of understanding and completion. The Mandarin PEDS was independently evaluated by a pediatrician and a community nurse, and classified as high risk (≥two predictive concerns), medium risk (one predictive concern), low risk (any non-predictive concerns) or no risk (if no concern) for developmental delays. The caregivers repeated Mandarin PEDS at a 2 week interval for test-retest reliability, while the children underwent testing for accuracy using a developmental assessment test.
RESULTS: The majority (≥85%) of the 73 caregivers perceived the Mandarin PEDS as acceptable and useful, as well as easy to understand and complete. Fifteen (20.5%) and 24 responses (33.9%) were classified as high and moderate risk, respectively. The test-retest and inter-rater reliabilities were excellent, with an intra-class correlation coefficient of 0.812 (95% CI: 0.701-0.881, P

Yong GY, Pan SW, Humayun Akhter F, Law TN, Toh TH

Asia Pac J Ophthalmol (Phila), 2016;5(2):137-42.
PMID: 26693590 DOI: 10.1097/APO.0000000000000150

PURPOSE: To study the demographic characteristics of ocular trauma in Central Sarawak and identify the determinant factors of poor visual outcome.
DESIGN: A retrospective study of ocular trauma cases presenting at the referral hospital in 2013.
METHODS: Patients were identified and recruited from hospital records. Those presenting for follow-up review were excluded. Case records were retrieved and reviewed after recruitment.
RESULTS: We studied 168 patients with 179 ocular injuries, of which 44% were work related. Compared with non-work-related cases, work-related cases were more likely to be male [odds ratio (OR), 19.7; 95% confidence interval (CI), 2.6-150.9] and foreign (OR, 18.0; 95% CI, 2.3-142.0). Open globe injuries constituted a higher percentage of impaired visual acuity (VA) during the first visit: 84.6% compared with 18.1% for closed globe injuries (OR, 25.0; 95% CI, 5.3-118.4; P < 0.001). Of the open globe injuries, 61.5% worsened or showed no improvement in VA after 3 months compared with closed globe injuries (28.9%) (OR, 3.9; 95% CI, 1.2-12.7; P = 0.015). Of cases presenting 7 or more days after trauma, 76.9% worsened or showed no improvement in VA after 3 months compared with those presenting in less than 7 days (27.7%) (OR, 8.7; 95% CI, 2.3-33.0; P < 0.001). Among those with work-related injuries, 23.1% had used eye protective devices (EPDs).
CONCLUSIONS: Ocular injuries in Central Sarawak were predominantly work related, occurring at industrial premises, and involving males and foreigners. Both open globe injuries and a delay in seeking treatment resulted in significantly poorer visual outcomes.

Animal alphacoronaviruses found in human patients with acute respiratory illness in different countries

Vlasova AN, Toh TH, Lee JS, Poovorawan Y, Davis P, Azevedo MSP, et al.

Emerg Microbes Infect, 2022 Feb 14.
PMID: 35156544 DOI: 10.1080/22221751.2022.2040341

Here we review the existing evidence of animal alphacoronaviruses (Alphacoronavirus 1 species) circulating in human patients with acute respiratory illness. Thus far, the viruses similar to canine, feline and porcine alphacoronaviruses (including the most recent CCoV-HuPn-2018 and HuCCoV_Z19) have been detected in humans in Haiti, Malaysia, Thailand, and USA. The available data suggest that these viruses emerged in different geographic locations independently and have circulated in humans for at least 20 years. Additional studies are needed to investigate their prevalence and disease impact.
Fulltext Novel Canine Coronavirus Isolated from a Hospitalized Patient With Pneumonia in East Malaysia

Vlasova AN, Diaz A, Damtie D, Xiu L, Toh TH, Lee JS, et al.

Clin Infect Dis, 2022 Feb 11;74(3):446-454.
PMID: 34013321 DOI: 10.1093/cid/ciab456

BACKGROUND: During the validation of a highly sensitive panspecies coronavirus (CoV) seminested reverse-transcription polymerase chain reaction (RT-PCR) assay, we found canine CoV (CCoV) RNA in nasopharyngeal swab samples from 8 of 301 patients (2.5%) hospitalized with pneumonia during 2017-2018 in Sarawak, Malaysia. Most patients were children living in rural areas with frequent exposure to domesticated animals and wildlife.
METHODS: Specimens were further studied with universal and species-specific CoV and CCoV 1-step RT-PCR assays, and viral isolation was performed in A72 canine cells. Complete genome sequencing was conducted using the Sanger method.
RESULTS: Two of 8 specimens contained sufficient amounts of CCoVs as confirmed by less-sensitive single-step RT-PCR assays, and 1 specimen demonstrated cytopathic effects in A72 cells. Complete genome sequencing of the virus causing cytopathic effects identified it as a novel canine-feline recombinant alphacoronavirus (genotype II) that we named CCoV-human pneumonia (HuPn)-2018. Most of the CCoV-HuPn-2018 genome is more closely related to a CCoV TN-449, while its S gene shared significantly higher sequence identity with CCoV-UCD-1 (S1 domain) and a feline CoV WSU 79-1683 (S2 domain). CCoV-HuPn-2018 is unique for a 36-nucleotide (12-amino acid) deletion in the N protein and the presence of full-length and truncated 7b nonstructural protein, which may have clinical relevance.
CONCLUSIONS: This is the first report of a novel canine-feline recombinant alphacoronavirus isolated from a human patient with pneumonia. If confirmed as a pathogen, it may represent the eighth unique coronavirus known to cause disease in humans. Our findings underscore the public health threat of animal CoVs and a need to conduct better surveillance for them.
Fulltext A RT-PCR assay for the detection of coronaviruses from four genera

Xiu L, Binder RA, Alarja NA, Kochek K, Coleman KK, Than ST, et al.

J Clin Virol, 2020 07;128:104391.
PMID: 32403008 DOI: 10.1016/j.jcv.2020.104391

BACKGROUND: During the past two decades, three novel coronaviruses (CoVs) have emerged to cause international human epidemics with severe morbidity. CoVs have also emerged to cause severe epidemics in animals. A better understanding of the natural hosts and genetic diversity of CoVs are needed to help mitigate these threats.
OBJECTIVE: To design and evaluate a molecular diagnostic tool for detection and identification of all currently recognized and potentially future emergent CoVs from the Orthocoronavirinae subfamily.
STUDY DESIGN AND RESULTS: We designed a semi-nested, reverse transcription RT-PCR assay based upon 38 published genome sequences of human and animal CoVs. We evaluated this assay with 14 human and animal CoVs and 11 other non-CoV respiratory viruses. Through sequencing the assay's target amplicon, the assay correctly identified each of the CoVs; no cross-reactivity with 11 common respiratory viruses was observed. The limits of detection ranged from 4 to 4 × 102 copies/reaction, depending on the CoV species tested. To assess the assay's clinical performance, we tested a large panel of previously studied specimens: 192 human respiratory specimens from pneumonia patients, 5 clinical specimens from COVID-19 patients, 81 poultry oral secretion specimens, 109 pig slurry specimens, and 31 aerosol samples from a live bird market. The amplicons of all RT-PCR-positive samples were confirmed by Sanger sequencing. Our assay performed well with all tested specimens across all sample types.
CONCLUSIONS: This assay can be used for detection and identification of all previously recognized CoVs, including SARS-CoV-2, and potentially any emergent CoVs in the Orthocoronavirinae subfamily.
Fulltext Surveillance for respiratory syncytial virus and parainfluenza virus among patients hospitalized with pneumonia in Sarawak, Malaysia

Fieldhouse JK, Toh TH, Lim WH, Ting J, Ha SJ, Hii KC, et al.

PLoS One, 2018;13(8):e0202147.
PMID: 30110367 DOI: 10.1371/journal.pone.0202147

BACKGROUND: Respiratory syncytial virus (RSV) and parainfluenza virus (PIV) are frequent causes of pneumonia and death among children at Sibu and Kapit Hospitals in Sarawak, Malaysia.
OBJECTIVES: To determine the prevalence and risk factors for RSV subtypes A and B and PIV types 1-4 among patients hospitalized with pneumonia.
METHODS: In a cross-sectional, pilot study nasopharyngeal swabs were studied with real-time reverse transcription polymerase chain reaction assays. Concurrently, we helped Sibu and Kapit Hospitals adapt their first molecular diagnostics for RSV and PIV.
RESULTS: Of 129 specimens collected (June to July 2017), 39 tested positive for RSV-A (30.2%), two were positive for RSV B (1.6%), one was positive for PIV-3 (0.8%) and one was positive for PIV-4 (0.8%). No samples were positive for PIV-1 or PIV-2. Of the 39 RSV-A positive specimens, 46.2% were collected from children under one year of age and only 5.1% were from patients over the age of 18. A multivariable analysis found the odds of children <1 year of age testing positive for RSV-A were 32.7 (95% CI: 3.9, 276.2) times larger than >18 years of age, and the odds of patients hospitalized at Kapit Hospital testing positive for RSV-A were 3.2 (95% CI: 1.3, 7.8) times larger than patients hospitalized at Sibu Hospital.
CONCLUSION: This study found an unusually high prevalence of RSV-A among pneumonia patients admitted to the two hospitals. Subsequently, Sibu Hospital adapted the molecular assays with the goal of providing more directed care for such pneumonia patients.
Fulltext First sequence of influenza D virus identified in poultry farm bioaerosols in Sarawak, Malaysia

Bailey ES, Fieldhouse JK, Alarja NA, Chen DD, Kovalik ME, Zemke JN, et al.

Trop Dis Travel Med Vaccines, 2020;6:5.
PMID: 32190346 DOI: 10.1186/s40794-020-0105-9

In 2018, our team collected aerosols samples from five poultry farms in Malaysia. Influenza D virus was detected in 14% of samples. One sample had an 86.3% identity score similar to NCBI accession number MH785020.1. This is the first molecular sequence of influenza D virus detected in Southeast Asia from a bioaerosol sample. Our findings indicate that further study of role of IDV in poultry is necessary.
Fulltext Immunogenicity and Safety of a Tetravalent Dengue Vaccine Administered Concomitantly or Sequentially With Quadrivalent Human Papillomavirus Vaccine in Boys and Girls 9-13 Years of Age in Malaysia: A Phase IIIb, Randomized, Open-label Study

Hassan J, Toh TH, Sivapunniam SK, Hasim R, Ghazali NF, Sulaiman S, et al.

Pediatr Infect Dis J, 2021 08 01;40(8):774-781.
PMID: 34250977 DOI: 10.1097/INF.0000000000003164

BACKGROUND: Incorporating dengue vaccination within existing vaccination programs could help improve dengue vaccine coverage. We assessed the immunogenicity and safety of a quadrivalent human papillomavirus (HPV) vaccine administered concomitantly or sequentially with a tetravalent dengue vaccine (CYD-TDV) in healthy children 9-13 years of age in Malaysia.
METHODS: In this phase IIIb, open-label, multicenter study (NCT02993757), participants were randomized 1:1 to receive 3 CYD-TDV doses 6 months apart and 2 doses of quadrivalent HPV vaccine concomitantly with, or 1 month before (sequentially), the first 2 CYD-TDV doses. Only baseline dengue-seropositive participants received the 3 doses. Antibody levels were measured at baseline and 28 days after each injection using an enzyme-linked immunosorbent assay for HPV-6, -9, -16 and -18, and the 50% plaque reduction neutralization test for the 4 dengue serotypes; immunogenicity results are presented for baseline dengue-seropositive participants. Safety was assessed throughout the study for all participants.
RESULTS: At baseline, 197 of 528 (37.3%) randomized participants were dengue-seropositive [n = 109 (concomitant group) and n = 88 (sequential group)]. After the last HPV vaccine dose, antibody titers for HPV among baseline dengue-seropositive participants were similar between treatment groups, with between-group titer ratios close to 1 for HPV-6 and 0.8 for HPV-11, -16, and -18. After CYD-TDV dose 3, dengue antibody titers were similar between treatment groups for all serotypes [between-group ratios ranged from 0.783 (serotype 2) to 1.07 (serotype 4)]. No safety concerns were identified.
CONCLUSIONS: The immunogenicity and safety profiles of CYD-TDV and quadrivalent HPV vaccines were unaffected when administered concomitantly or sequentially in dengue-seropositive children.
Fulltext A pan-coronavirus RT-PCR assay for rapid viral screening of animal, human, and environmental specimens

Wang X, Xiu L, Binder RA, Toh TH, Lee JS, Ting J, et al.

One Health, 2021 Dec;13:100274.
PMID: 34124332 DOI: 10.1016/j.onehlt.2021.100274

We examined a collection of 386 animal, 451 human, and 109 archived bioaerosol samples with a new pan-species coronavirus molecular assay. Thirty-eight (4.02%) of 946 specimens yielded evidence of human or animal coronaviruses. Our findings demonstrate the utility of employing the pan-CoV RT-PCR assay in detecting varied coronavirus among human, animal, and environmental specimens. This RT-PCR assay might be employed as a screening diagnostic for early detection of coronaviruses incursions or prepandemic coronavirus emergence in animal or human populations.
