Norhafizah S, Salina H, Goh BS

Eur Ann Allergy Clin Immunol, 2020 05;52(3):121-130.
PMID: 31668057 DOI: 10.23822/EurAnnACI.1764-1489.119

Summary: Introduction.The prevalence of allergic rhinitis in children with persistent otitis media with effusion in different countries varies between 82% to 93%. Many risk factors of otitis media with effusion has been studied and proven. However, its association with allergic rhinitis remains controversial. Objective. The main objective of this study is to determine the prevalence of allergic rhinitis in children with persistent otitis media with effusion. This study is also aimed to identify the risk factors of otitis media with effusion, common allergens associated with allergic rhinitis and determine the hearing threshold of children with otitis media with effusion. Methods.A hundred and thirty children were recruited. History taking, physical examination and hearing assessment were done in the first visit. Those with allergic rhinitis underwent skin prick test and treated with intranasal corticosteroid and antihistamine. A second examination and hearing assessment were then repeated after 3 months. Results.The prevalence of allergic rhinitis in children with persistent otitis media with effusion in this study was noted to be 80.3%. Among these children, dust mites appeared to be the most common allergen (87.7%). Another risk factor appeared to be families with more than 4 members per-household (96%). It is noted that that otitis media with effusion caused a hearing loss up to 33 dB. However, there was a statistically significant improvement of the hearing threshold during second visit after commencement of allergy treatment. It was also noted that the hearing threshold in allergic rhinitis group was significantly impaired compared to the non-allergic rhinitis group. Conclusions.Allergic rhinitis and larger family household appeared to be common risk factors in children with persistent otitis media with effusion. There is significant hearing loss noted in children suffering from otitis media with effusion and allergic rhinitis. The hearing threshold improved remarkably with medical therapy. This study hence clarifies the controversy on the association between allergic rhinitis and otitis media with effusion.

Multiphasic disseminated encephalomyelitis followed by optic neuritis in a child with gluten sensitivity

Ching BH, Mohamed AR, Khoo TB, Ismail HI

Mult Scler, 2015 Aug;21(9):1209-11.
PMID: 26199345 DOI: 10.1177/1352458515593404

Multiphasic disseminated encephalomyelitis (MDEM) followed by optic neuritis (ON) has been described as a new entity in recent years. Gluten encephalopathy has also been recognized as a neurological manifestation of celiac disease. Accurate diagnosis of both is important due to the therapeutic implications. We report a girl presenting with recurrent encephalopathic polyfocal demyelinating episodes followed by optic neuritis, and a clinical history suggestive of gluten sensitivity. She had persistently high ESR, neutrophilia, and tested positive for anti-MOG (myelin oligodendrocyte glycoprotein) antibody. She responded well to methylprednisolone in each relapse, and achieved remission for a year after azathioprine was added.

Fulltext Corneal laceration caused by river crab

Vinuthinee N, Azreen-Redzal A, Juanarita J, Zunaina E

Clin Ophthalmol, 2015;9:203-6.
PMID: 25678769 DOI: 10.2147/OPTH.S74548

A 5-year-old boy presented with right eye pain associated with tearing and photophobia of 1-day duration. He gave a history of playing with a river crab when suddenly the crab clamped his fingers. He attempted to fling the crab off, but the crab flew and hit his right eye. Ocular examination revealed a right eye corneal ulcer with clumps of fibrin located beneath the corneal ulcer and 1.6 mm level of hypopyon. At presentation, the Seidel test was negative, with a deep anterior chamber. Culture from the corneal scrapping specimen grew Citrobacter diversus and Proteus vulgaris, and the boy was treated with topical gentamicin and ceftazidime eyedrops. Fibrin clumps beneath the corneal ulcer subsequently dislodged, and revealed a full-thickness corneal laceration wound with a positive Seidel test and shallow anterior chamber. The patient underwent emergency corneal toileting and suturing. Postoperatively, he was treated with oral ciprofloxacin 250 mg 12-hourly for 1 week, topical gentamicin, ceftazidime, and dexamethasone eyedrops for 4 weeks. Right eye vision improved to 6/9 and 6/6 with pinhole at the 2-week follow-up following corneal suture removal.

Mohammad Azmi HH, Goh BS, Abdullah A, Umat C

Acta Otolaryngol, 2020 Oct;140(10):838-844.
PMID: 32564640 DOI: 10.1080/00016489.2020.1775887

INTRODUCTION: Bilateral cochlear implants are seen to improve hearing capabilities.
OBJECTIVE: To assess the auditory outcome of paediatric bilateral cochlear implant in Universiti Kebangsaan Malaysia.
MATERIALS AND METHODS: This was a cross-sectional and descriptive study single centre analysis. Categories of Auditory Performance (CAP-II) scale and Speech, Spatial and Qualities (SSQ) of Hearing questionnaire were used.
RESULTS: Forty-six patients were recruited. Majority of the children (30.4%) rated 7 and 23.9% scored perfectly (9) based on the CAP-II Scale. The least performing children were rated 5 (average). Children that were implanted sequentially within 24 months showed median CAP-II scale of 7. No significant correlation seen between CAP-II and the duration interval, use and age of 1st CI (p > .05). The speech domain of SSQ-P scale showed median value of 8 indicating good speech understanding. The spatial hearing domain had median value of 7, quality of hearing domain had median of 8. Significant correlation seen in hearing in noise with the duration of use of CI (p

Syntactic Cues Help Disambiguate Objects Referred to With Count Nouns: Illustration With Malay Children

Sia MY, Mayor J

Child Dev, 2021 01;92(1):101-114.
PMID: 32738160 DOI: 10.1111/cdev.13401

Children employ multiple cues to identify the referent of a novel word. Novel words are often embedded in sentences and children have been shown to use syntactic cues to differentiate between types of words (adjective vs. nouns) and between types of nouns (count vs. mass nouns). In this study, we show that children learning Malay (N = 67), a numeral classifier language, can use syntactic cues to perform even finer-grained disambiguation-between count nouns. The manipulation of congruence between lexical and syntactic cues reveals a clear developmental trajectory: while 5-year-olds use predominantly lexical cues, older children increasingly rely on syntactic cues, such that by 7 years of age, they disambiguate between objects referred to with count nouns using syntactic rather than lexical cues.

Fulltext Nutritional Assessment of Pre-School Children in Rural Villages of the Family Dynamics, Lifestyles and Nutrition Study (1997-2001) II. Prevalence of Undernutrition and Relationship to Household Socio-Economic Indicators

Chee H, Khor G, Arshad F, Wan Muda W, Mohdtaib M, Safii N, et al.

Malays J Nutr, 2002 Mar;8(1):33-53.
PMID: 22692438

This paper describes the nutritional status of pre-school children and analyzes its relationship to various household socio-economic indicators. Padi, rubber and fishing villages from the Functional Groups Study (1992-1996) were selected for having a high prevalence of child undernutrition, and all children between the ages of 12 and 72 months were measured for their weights and heights in April-May 1998. The NCHS reference values were used to calculate z-scores, which were categorised according to WHO (1983) recommendations. Children between minus 2SD and minus 1SD of reference median were classified as mildly malnourished. Prevalence of underweight was higher (30.5%) than stunting (22.3%), while wasting was only 9.7%. Padi villages had the highest prevalence of undernutrition, followed by fishing, and then rubber villages. Mean household incomes were found to be significantly lower for children with worse nutritional status, and undernutrition was higher in households below the poverty line income. The odds ratios for having stunted children were significantly higher for households whose heads were agricultural own-account workers (OR 3.66, 95% CI = 1.37-9.79), agricultural waged workers (OR 2.75, 95% CI = 1.06-7.10), and non-agricultural manual workers (OR 2.49, 95% CI = 1.04-6.00) compared to non-manual workers. Various household socio-economic indicators showed significantly higher odds ratios for underweight, stunting and wasting. After adjusting for confounding effects by logistic regression analysis, however, only mother's education was found to be a significant predictor for stunting, while poverty level and access to piped water supply were significant predictors for both underweight and stunting. Households without livestock were significant predictors for wasting. Thus, this study identified specific socio-economic factors that should be prioritized for policy and research towards the amelioration of childhood malnutrition in rural areas.

Fulltext Assessment of food insecurity among low income households in kuala lumpur using the radimer/cornell food insecurity instrument - a validation study

Sharif ZM, Ang M

Malays J Nutr, 2001 Mar;7(1):15-32.
PMID: 22692426

Food insecurity exists whenever people are not able to access sufficient food at all times for an active and healthy life. This study used the Radimer/Cornell hunger and food insecurity instrument to assess food insecurity and to determine the risk factors and consequences of food insecurity among low-income households in Kuala Lumpur. One hundred and thirty-seven Malay pre-school children (4-6 years old) from Taman Sang Kancil were measured for their weights and heights. Questionnaires were used to collect food security and socioeconomic information on the households. The findings indicated that 34.3% of the households were food secure, while 65.7% experienced some kind of food insecurity, (27.7% households were food insecure, 10.9% individuals were food insecure and 27.0% fell into the child hunger category). The prevalence of underweight, stunting and wasting were 44.5%, 36.5% and 30.7% respectively. The prevalence of high weight-for-height (overweight) was 13.1%. Based on multinomial logistic regression, larger household size (OR=1.418; p<0.01) and lower educational level of mothers (OR=0.749; p<0.01) and fathers (OR=0.802; p<0.05) were found to be significant risk factors for food insecurity. The study, however, did not find any significant difference in children's nutritional status according to household food security levels. It is recommended that for the Malaysian population, the Radimer/Cornell hunger and food insecurity instrument should be modified and further validated with various ethnic groups in a variety of settings. The validation should include the appropriateness of the statements to the target grounds and their different risk factors and outcomes of food insecurity.

MyJurnal

Introduction: The Infant and Early Childhood Nutrition Task Force, International Life Sciences Institute Southeast Asia (ILSI SEA) Region, organised the 1st and 2nd Expert Consultation and Planning Meeting on Infant and Early Childhood Nutrition in 2009 and 2011, respectively. The goal of the consultations was “to generate and promote relevant science-based information that will help improve nutritional status, growth and development of infants and young children in Southeast Asia.” Methods: An Expert Panel Core Group was created whose role is to provide advice and recommendations through a review of current scientific knowledge regarding issues related to early childhood growth and nutrition. The Panel is composed of experts representing 7 countries (China, Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam). In July 2012, the Panel convened the 3rd Expert Consultation and Planning Meeting on Infant and Young Child Nutrition in Singapore. This report presents the highlights of the meeting and recommendations made by the Panel on ways to improve infant and young child nutrition in Southeast Asia. Results and Conclusion: The effective use of WHO indicators for assessing infant and young child feeding practices, mitigating the effects of maternal employment on breastfeeding, using behaviour change communication, updating the education of health personnel, and improving maternal health were considered important actions to be taken. Since current feeding practices in Southeast Asia fall short of WHO recommendations, studies are needed to develop strategies which take into consideration the diverse cultural settings that characterise the region.

Introduction: Otanges in children's food habits are largely attributed to changes in the family and social environment. 1bis cross-sectional study was carried out to determine the association of socio-demographic factors with food habits among preschool children in Peninsular Malaysia. Methods: A total of 1,933 preschool children aged 4-6 years old participated in the study. Parents or guardians were interviewed on the socio-demographic characteristics and food habits of their children. Height and weight of the preschoolers were measured; BMI-for-age, weight-for-age and height-for-age were determined. Results: The mean monthly household income was RM3,610 with 59.6% of parents having attained secondary education. The prevalence of possible risk of overweight, being overweight and obesity were 3.9%, 7.9% and 8.1%, respectively while the prevalence of underweight and stunting was 8.0% and 8.4%. A majority of the preschoolers consumed breakfast, lunch and dinner every day, with the proportion of children skipping their main meals at about 15.0%. Parents' education level and household income were significantly associated with intakes of fruits, vegetables, milk and dairy products, as well as fast food. However, there was no significant association between children's body weight status and frequency of main meals intake, fruits, vegetables, milk and dairy products, and fast food intake. Conclusion: The preschoolers demonstrated moderately healthy food habits; nevertheless even at this young age, they were inclined towards fried foods, snacking and fast foods intake. Parents and guardians should play a more significant role in educating and promoting good nutrition and food habits among preschoolers.

Introduction: Childhood stunting is recognised as one of the most significant
barriers to human development. This cross-sectional study aimed to determine the
factors associated with stunting among Orang Asli (OA) preschool children in Negeri
Sembilan, Malaysia.

Methods: A total of 264 children (50.9% boys and 49.1%
girls) aged 2-6 years (M=4.04, SD=1.21 years) including their mothers from 14 OA
villages in Negeri Sembilan participated in this study. Mothers were interviewed to
obtain information regarding socioeconomic status, sanitation facility and personal
hygiene. The height of the children and their mothers were measured. Venous
blood samples were drawn from the children to estimate haemoglobin level, and
stool samples were collected to screen for intestinal parasitic infections.

Results:
Approximately one third of the children (35.6%) and 7.8% of the mothers were
stunted. One in five of the children were anaemic (21.6%), while one- third had
intestinal parasitic infections (35.0%). Low birth weight (AOR=2.526, 95% CI: 1.310-
4.872; p=0.006), anaemia (AOR=2.742, 95% CI: 1.265-5.945; p=0.011), presence
of intestinal parasitic infections (AOR=2.235, 95% CI: 1.310-3.813, p=0.003), not
wearing shoes (AOR=2.602, 95% CI: 1.453-4.660; p=0.001), absence of piped water
at home (AOR=2.395, 95% CI: 1.047-5.476; p=0.039), dirty nails (AOR=1.956, 95%
CI: 1.163-3.289, p=0.011), and stunted mothers (AOR=3.443, 95% CI: 1.334-8.890;
p=0.011) were identified as significant factors for childhood stunting.

Conclusion:
It is suggested that the factors identified associated with childhood stunting be
included in future intervention programmes that address stunting among OA
children.

Extramedullary CD20-positive B-lymphoblastic lymphoma in a 5-year-old child: A diagnostic challenge

Abdul Jalil D, Raja Sabudin RZA, Tang YL, Masir N

Malays J Pathol, 2020 Aug;42(2):273-276.
PMID: 32860381

INTRODUCTION: Lymphoblastic leukaemia/lymphoma may present as an isolated extramedullary mass, which includes the musculoskeletal region involvement with normal or near-normal blood counts. The tumour may be in the form of B or T-lymphoblastic leukaemia/lymphoma. The clinical features and histological morphology of extramedullary B-lymphoblastic lymphoma (B-LBL) may mimic mature B-cell neoplasms, thus posing a diagnostic challenge. Arriving at the right diagnosis is crucial because these two diseases differ in their prognosis and management. A high index of suspicion is therefore important so as not to miss the correct diagnosis. The diagnosis may be overlooked because the clinical presentation may not be typical of B-LBL or the blood counts do not show any abnormalities. In this report, we highlight one such case where the diagnosis of B-LBL was missed because of its atypical presentation.

Estimating the Productivity Burden of Pediatric Pneumococcal Disease in Thailand

Ounsirithupsakul T, Dilokthornsakul P, Kongpakwattana K, Ademi Z, Liew D, Chaiyakunapruk N

Appl Health Econ Health Policy, 2020 08;18(4):579-587.
PMID: 32009211 DOI: 10.1007/s40258-020-00553-0

BACKGROUND: Pneumococcal diseases were estimated to cause 1.6 million deaths annually worldwide in 2008, with approximately half of these occurring in children aged under 5 years. The consequences and deaths adversely impact individuals' and caregivers' work productivity.
OBJECTIVES: This study aimed to quantify the potential lifetime productivity loss due to pneumococcal diseases among the pediatric population in Thailand using productivity-adjusted life years (PALYs).
METHODS: A decision analytic model was used to estimate the burden of pneumococcal diseases among the current Thai population aged 0-5 years and followed up until aged 99 years or death. Base-case analysis compared years of life and PALYs lost to pneumococcal diseases. Scenario analyses investigated the benefits of prevention with pneumococcal conjugated vaccine 13 (PCV 13). All health outcomes were discounted at 3% per annum.
RESULTS: The base-case analysis estimated that 453,401 years of life and 457,598 PALYs would be lost to pneumococcal diseases, equating to a loss of US$5586 (95% CI 3338-10,302) million. Vaccination with PCV13 at birth was estimated to save 82,609 years of life and 93,759 PALYs, which equated to US$1144 (95% CI 367-2591) million in economic benefits. The incidence of pneumonia in those aged 0-4 years, vaccine efficacy, and the assumed period of protection were key determinants of the health economic outputs.
CONCLUSIONS: The disease and financial burden of pneumococcal diseases in Thailand is significant, but a large proportion of this is potentially preventable with vaccination.

Two novel polyadenylation mutations leading to beta(+)-thalassemia

Jankovic L, Efremov GD, Petkov G, Kattamis C, George E, Yang KG, et al.

Br J Haematol, 1990 May;75(1):122-6.
PMID: 2375910

In an ongoing effort to identify point mutations causing beta-thalassaemia, we have found two previously unreported mutations which are located in the Poly A site of the beta-globin gene. The screening programme used amplified DNA and dot-blot hybridization with several 32P-labelled oligonucleotide probes. DNA samples which remained unidentified by this methodology were subjected to sequencing with 32P-labelled primers and modified T7 DNA polymerase. The newly discovered mutations were confirmed by the dot-blot hybridization technique. One type concerned an AATAAA----AATGAA mutation in the polyadenylation site and was found in one family from Yugoslavia (including one patient with the C----T mutation at codon 29 in trans), one from Bulgaria (the patient had the G----A mutation at IVS-I-110 in trans), and one from Greece (this patient had the C----G mutation at IVS-II-745 in trans). Haematological data for three simple heterozygotes suggested a rather mild beta(+)-thalassemia. The second type involved an AATAAA----AATAGA mutation and was found in one family from Malaysia. The propositus had the beta E mutation on the other chromosome, was originally diagnosed as mild Hb E-beta(+)-thalassaemia, and had Hb A and Hb E percentages which were nearly the same.

PMID: 30465638 DOI: 10.1099/jmm.0.000881

Sporadic diphtheria cases in Malaysia have remained low in number since the 1990s. However, in 2016 a total of 31 cases were reported nationwide and to investigate this we performed molecular characterization of 30 Corynebacterium diphtheriae isolates collected from 1981 to 2016 using multilocus sequence typing (MLST). C. diphtheriae isolates were identified and biotyped using the API Coryne kit, while the toxigenicity was determined by PCR and the Elek test. All of the 2016 isolates belonged to biotype mitis, caused respiratory diphtheria and were toxigenic strains. MLST analysis identified 17 sequence types (STs), including 11 new ones. ST453 was the most common clone (7/30, 23.3 %), followed by ST141 (5/30, 16.7 %), ST451 (3/30, 10.0 %) and ST248 (2/30, 6.7 %). The clones identified in 2016 had not been detected in previous isolations and they were phylogenetically distinct. Our results suggest that the diphtheria cases in 2016 were caused by the emergence and spread of new clones in Malaysia.

Fulltext Pharmacokinetics of a novel sublingual spray formulation of the antimalarial drug artemether in African children with malaria

Salman S, Bendel D, Lee TC, Templeton D, Davis TM

Antimicrob Agents Chemother, 2015;59(6):3208-15.
PMID: 25801552 DOI: 10.1128/AAC.05014-14

The pharmacokinetics of sublingual artemether (ArTiMist) was investigated in 91 young African children with severe malaria or who could not tolerate oral antimalarial therapy. Each received 3.0 mg/kg of body weight of artemether at 0, 8, 24, 36, 48, and 60 h or until the initiation of oral treatment. Few blood samples were drawn postdose. Plasma artemether and dihydroartemisinin (DHA) levels were measured using liquid chromatography-mass spectrometry, and the data were analyzed using established population compartmental pharmacokinetic models. Parasite clearance was prompt (median parasite clearance time, 24 h), and there were no serious adverse events. Consistent with studies in healthy adults (S. Salman, D. Bendel, T. C. Lee, D. Templeton, and T. M. E. Davis, Antimicrob Agents Chemother 59:3197-3207, 2015, http://dx.doi.org/10.1128/AAC.05013-14), the absorption of sublingual artemether was biphasic, and multiple dosing was associated with the autoinduction of the metabolism of artemether to DHA (which itself has potent antimalarial activity). In contrast to studies using healthy volunteers, pharmacokinetic modeling indicated that the first absorption phase did not avoid first-pass metabolism, suggesting that the drug is transferred to the upper intestine through postdose fluid/food intake. Simulations using the present data and those from an earlier study in older Melanesian children with uncomplicated malaria treated with artemether-lumefantrine tablets suggested that the bioavailability of sublingual artemether was at least equivalent to that after conventional oral artemether-lumefantrine (median [interquartile range] areas under the concentration-time curve for artemether, 3,403 [2,471 to 4,771] versus 3,063 [2,358 to 4,514] μg · h/liter, respectively; and for DHA, 2,958 [2,146 to 4,278] versus 2,839 [1,812 to 3,488] μg · h/liter, respectively; P ≥ 0.42). These findings suggest that sublingual artemether could be used as prereferral treatment for sick children before transfer for definitive management of severe or moderately severe malaria.

PMID: 2339437

The records associated with 83 children from 16 months to 12 years of age who were admitted with snake bite to Kota Bharu General Hospital and University Hospital, Universiti Sains Malaysia over a 5 year period were reviewed. Elapid bites were more common than viper bites while sea-snake bites were not recorded. Symptoms were relatively mild, the common clinical features being pain and local swelling. Antivenom therapy was required in 11 children. Only three of the 11 children developed minor adverse reactions to antivenom. Four of the 83 required ventilatory support for respiratory failure and two children died.

PMID: 25776610 MyJurnal

Limited data is available on the prevalence of parasitic infections among the island communities in Malaysia with most studies performed between 1960s-1980s. This study was conducted to determine the current prevalence status of parasitic infections among communities living in Pangkor Island Peninsular Malaysia. A total of 131 stool and 298 serum samples were collected and subjected to microscopic examination for intestinal protozoa and helminths and detection of Toxoplasma gondii antibodies using commercial ELISA kits respectively. In addition, thin and thick peripheral blood films were microscopically screened for the presence of Plasmodium spp. and microfilariae respectively. The overall prevalence of intestinal parasitic infections among Pangkor Island community was 9.9% (13/131) with T. trichiura (5.3%) being the most common intestinal parasite detected. Toxoplasmosis was reported in almost 60% of the community with the seroprevalence being significantly high among females (64.7%) compared to males (52.8%) (p=0.038). None of those examined samples were infected with intestinal sarcocystosis, malaria and filariasis. This study revealed that the prevalence of intestinal parasitic infections among Pangkor Island community has been greatly reduced compared to that reported 35 years ago. Massive improvements in the socioeconomic status, personal hygiene, water facilities and sanitation may have contributed to the low prevalence of parasitic infections in this community. Nevertheless, further studies still need to be performed to determine the possible risk factors for the high prevalence of toxoplasmosis in this community.

Intestinal parasitic infections are among the most common diseases affecting mankind causing major public health problems to billions of people living in developing countries. The aim of this study is to determine the prevalence of intestinal parasites in various communities residing in different habitats in Malaysia and compare the findings with 101 studies conducted over the past 42 years (1970-2013). A cross-sectional study design was conducted with the aid of a questionnaire to collect relevant information about the study population. Faecal samples were examined using the direct smear and formal ether sedimentation techniques. A total of 342 children were examined amongst whom 24.6% were positive for intestinal parasitic infections. Results showed that 32.3% of rural children, 20.6% of urban squatters and 5.4% of children from flats were positive for one or more parasites. The most common parasite encountered was Trichuris trichiura (20.2%) followed by Ascaris lumbricoides (10.5%) and hookworm (6.7%). No case of hookworm was reported in urban children whereas 12.2% of rural children were positive. The most common protozoan parasite detected was Entamoeba coli (3.2%) followed by Giardia intestinalis (1.8%), Entamoeba histolytica (1.8%) and Blastocystis hominis (1.2%). Nearly one-fifth (18.4%) of the children had single infection followed by double (12.0%) and triple infections (1.2%). Orang Asli (indigenous) children (44.3%) had the highest infection rate followed by Indians (20.2%), Malays (14.0%) and Chinese (11.9%). Twenty-eight studies carried out on plantation communities with regards to intestinal parasitic infections in Malaysia from 1970 to 2013 showed a steady decline in the prevalence rate ranging from 95.0% in the seventies to 37.0 % in 2012. Intestinal parasitic infections were more common in Orang Asli communities with prevalence ranging from over 90% in the seventies and fluctuating below 70% in most studies between 2000 to 2013 except for two studies that showed a prevalence of 98.2% and 100%. The prevalence rate among urban squatters, urban residents and those living in flats showed dramatic decrease in prevalence rate.
