    PMID: 16898306 MyJurnal
    The prevalence of pain complaints as a reason for patient-doctor encounters in the local primary care setting is unknown. We performed a cross-sectional survey of such encounters in one public primary care clinic (KK) and 17 general practice clinics (GP), from the city of Seremban, Negeri Sembilan, Malaysia. Reasons for visits were recorded by doctors in KK and medical students in GP using a structured questionnaire. Morbidity data was coded using the International Classification of Primary Care (ICPC-2). A total of 2234 encounters were recorded (80.9% from KK, 19.1% from GP). The overall prevalence of pain complaints was 31.9% with a significant difference between the two cohorts (KK 28.7% and GP 45.2%, p<0.001). Musculoskeletal pain complaints were more common in KK than GP (40.9% versus 29.7%, p<0.05). Of the 3 main ethnic groups in Malaysia (Malay, Chinese and Indian) the Indian patients at KK had the highest prevalence of pain complaints and the Chinese at the GP had the lowest. Thus pain was a common complaint in the two different primary care settings studied. Some of the differences observed are probably due to the differences in the healthcare seeking behaviour of patients consulting at these two settings as well as differences in the payment systems.

    Keah SH, Ch'ng KS
    Malays Fam Physician, 2006;1(1):19-22.
    PMID: 26998203 MyJurnal
    The objective of this study was to determine the prevalence of diabetic retinopathy in a primary care setting using digital retinal imaging technology and to quantify the degree of diabetic retinopathy using internationally accepted severity scales. Two hundred patients with type 2 diabetes were evaluated clinically followed by fundus photography. The prevalence of retinopathy and maculopathy was 47.4% and 59.2% respectively (both retinopathy and maculopathy 34.7%). The high prevalence of retinal abnormality in this study is a cause for concern as most patients had diabetes for only 5 years or less.

  3. Ethnic differences in the time trend of female breast cancer incidence: Singapore, 1968-2002
    Sim X, Ali RA, Wedren S, Goh DL, Tan CS, Reilly M, et al.
    BMC Cancer, 2006;6:261.
    PMID: 17078893
    From 1968 to 2002, Singapore experienced an almost three-fold increase in breast cancer incidence. This increase appeared to be different across the three main ethnic groups: Chinese, Malays and Indians. This paper used age-period-cohort (APC) modelling, to determine the effects of age at diagnosis, calendar period, and birth cohort on breast cancer incidence for each ethnic group.

  4. DYT1 mutations amongst adult primary dystonia patients in Singapore with review of literature comparing East and West
    Jamora RD, Tan EK, Liu CP, Kathirvel P, Burgunder JM, Tan LC
    J Neurol Sci, 2006 Aug 15;247(1):35-7.
    PMID: 16631205
    Dystonia is a heterogenous group of movement disorders whose clinical spectrum is very wide. At least 13 different genes and gene loci have been reported. While a 3-bp deletion in the DYT1 gene is the most frequent cause of early limb-onset, generalized dystonia, it has also been found in non-generalized forms of sporadic dystonia. An 18-bp deletion in the DYT1 gene has also been reported.

    PMID: 16515102
    Sinusitis is an important cause of morbidity and one of the major sources of income loss. Anatomical variations of the nose have been reported to predispose to sinusitis. These variations include concha bullosa, nasal septal deviation and oversized bulla. The aim of this study was to determine the proportion and the distribution of concha bullosa in patients with chronic sinusitis and to determine the relationship between concha bullosa and age, sex, ethnicity. A cross-sectional study was conducted at the Department of Ear, Nose and Throat in Kuala Lumpur Hospital (HKL). Data was collected retrospectively using a pretested proforma. All patients who underwent Sino nasal surgery between January 1999 and December 2000 and whose preoperative CT scans were available were included in the study. The CT scans were reviewed. Analysis was carried out using Statistical Package for Social Sciences. Out of 146 patients who underwent sinonasal surgery between January 1999 and December 2000, 101 (69.2% preoperative CT scans of these patients were available and these were reviewed. The proportion of patients with concha bullosa was 49.5%. The results showed that there was significant relationship between presence of concha bullosa and age and sex. The overall mean age of patient with concha bullosa was 35.7 years (95% CI 12.1-39.3) and ranged from 11-years to 56-years. The mean age of respondents with concha bullosa was significantly lower than patients without concha bullosa 41.98 (95% CI 37.6-46.3; t-test = 2.221; df=99; p < 0.05). Concha bullosa was significantly more in females (66.0%) compared to males (chi2 = 4.465, df=1, p < 0.05). There was no significant relationship between presence of concha bullosa and ethnicity.

  8. Fulltext Body mass status of school children and adolescents in Kuala Lumpur, Malaysia
    Moy FM, Gan CY, Zaleha MK
    Asia Pac J Clin Nutr, 2004;13(4):324-9.
    PMID: 15563435
    Lifestyle and disease patterns in Malaysia have changed following rapid economic development. It is important to find out how these changes have affected the nutritional status and health behaviour of the population, especially school children and adolescents. Therefore a survey on school children's and adolescents' health behaviours and perception in Kuala Lumpur was initiated. This paper only reports the observed body mass status of the school children. A total of 3620 school children were selected in this survey using the method of multi-stage sampling. The students were surveyed using pre-tested questionnaires while weight and height were measured by the research team in the field. Using the cut-off of BMI-for-age >or= 95th percentile and <5th percentile for overweight and underweight respectively, there were a total of 7.3% of overweight students and 14.8% of underweight students. When analysed by gender; 7.5% of boys and 7.1% girls were overweight, while 16.2% of the boys and 13.3% of the girls were underweight. The youngest age group (11 years old) had the highest prevalence of underweight as well as overweight. With increasing age, the prevalence of underweight and overweight decreased and more children were in the normal weight range. The overall prevalence of overweight among the three ethnic groups was similar. However the prevalence of underweight was highest among the Indian students (24.9%), followed by Malays (18.9%) and Chinese (9.5%) (P <0.001). The results showed that both the problems of under- and over-nutrition co-exist in the capital city of Malaysia. The promotion of healthy eating and physical activities is required to address the problems of under- and over-nutrition in order to build up a strong and healthy nation in the future.

    Cheng N, Lee GK, Yap BS, Lee LT, Tan SK, Tan KP
    J Forensic Sci, 2005 Jan;50(1):177-84.
    PMID: 15831016
    This paper investigated the class characteristics in English handwriting of the Chinese, Malays and Indians in Singapore, many of whom learned their native language as a second language. One hundred and fifty-four handwriting exemplars were collected and features such as letter designs, pen-lifts, letter spacing and embellishments were studied. A number of characteristic features peculiar to the individual racial group were identified, which confirmed the impact of their native language writing systems on English handwriting.

    PMID: 16327344
    The diversity of Singapore's population affords a unique opportunity to study ethnic variability in the dementias. We sought to explore the effects of ethnicity on the frequency of Alzheimer disease and vascular dementia in a large Singaporean sample. A total of 357 patients were studied: 190 with vascular dementia and 167 with Alzheimer disease. Vascular dementia was more common among Chinese and Malays, whereas Alzheimer disease was more common in Indians and Eurasians. Factors that may contribute to the observed ethnic variability in dementia etiologies include differential frequency of the ApoE-e4 allele, frequency of vascular risk factors, lifestyle choices, and cultural attitudes toward health care utilization.

    PMID: 16279828
    The purpose of this study was to determine the occlusal status in young Asian male adults of three ethnic groups. Study models of a sample of male army recruits (N = 339, age 17-22 years) with no history of orthodontic treatment were assessed. The ethnic proportions of the sample were Chinese 76.1% (n = 258), Malay 17.7% (n = 60), and Indian 6.2% (n = 21). British Standard Institute (BSI) and Angle's classification were used to determine incisor and molar relationships, respectively. Chi-square test or Fisher's Exact test was performed to compare the occlusal traits between ethnic groups. The distribution of incisor relationships of the total sample consisted of Class I = 48.1%, Class II/1 = 26.3%, Class II/2 = 3.2%, and Class III = 22.4%. Right Angle's molar relationships were 49.9%, 24.5%, and 24.2% whereas left Angle's molar relationships were 53.1%, 25.1%, and 21.2% for Class I, II, and III, respectively. Comparison between ethnic groups found that Indian subjects were more likely to have Class II/1 malocclusions and clinically missing permanent teeth (P < .05). The study found that the overall prevalence of malocclusion (BSI) was Class I, Class II/1, Class III, and Class II/2 in descending order of proportions. Angle's Class I molar was most prevalent followed by Class II and Class III relations. A significant difference in occlusal status between the ethnic groups was found regarding incisor relationship and missing permanent teeth (P < .05).

    PMID: 15957725
    Differences in sensitivity to anaesthetic drugs may exist among different ethnic groups. Allelic variants for drug metabolizing isoenzymes and pharmacokinetic differences may account for a variable response to some anaesthetic drugs. This study was designed to compare propofol consumption and recovery characteristics in four ethnic groups: Chinese, Malays, and Indians in Malaysia and Caucasians in Italy. Patients undergoing total intravenous anaesthesia with propofol and fentanyl were evaluated for propofol consumption and recovery time. The Bispectral Index (BIS) was used to maintain the same anaesthesia depth in all patients. The BIS value, the response to verbal stimuli and eye-opening time were used to assess recovery. After propofol discontinuation the BIS values returned to baseline in 11+/-4.2 min for Caucasians, in 12.5+/-5.1 min for Chinese, 15.9+/-6.3 min for Malays and 22.1+/-8.1 for Indians. Time to eye-opening was 11.63+/-4.2 min in Caucasians, 13.23+/-4.9 min in Chinese, 16.97+/-5.2 min in Malays and 22.3+/-6.6 min in Indians. The propofol consumption was significantly lower in Indians compared to the other three groups (P<0.01). The recovery of Indians was much slower compared to Chinese, Malays and Caucasians. The recovery time of Malays is significantly slower compared to Chinese and Caucasians. Differences in propofol consumption and recovery time were not significant between Chinese and Caucasians, but the ratio recovery time/propofol consumption was significantly lower in Caucasians compared to all the other groups.

  15. Fulltext Views and experiences of Malaysian older persons about falls and their prevention-A qualitative study
    Loganathan A, Ng CJ, Low WY
    BMC Geriatr, 2016;16:97.
    PMID: 27153989 DOI: 10.1186/s12877-016-0274-6
    BACKGROUND: Few studies on falls interventions have been conducted in South East Asia. Despite its population ageing rapidly, the acceptability of interventions among the older population in this region remains variable. This study aims to explore views and experiences regarding falls and their prevention among older persons at high risk of falls.
    METHOD: Sixteen individuals aged 60 years and over with at least one fall in the preceding 12 months were recruited from our Primary Care clinics. A qualitative study using semi-structured interviews among individuals and focus-groups was conducted. Thematic analyses were conducted on transcriptions of audio-taped interviews using the WeftQDA software. The interviews ceased when data saturation was achieved.
    RESULTS: The three themes included older persons' views on falls, help-seeking behaviour and views on falls interventions. Many older persons interviewed did not perceive falls as a serious problem, some reported a stigma surrounding falls, while others felt they had not sustained more serious injuries due to God's grace. Older persons sought traditional medicine and other alternative treatments for pain relief and other fall-related symptoms. Accessibility of healthcare facilities often prevented older persons from receiving physiotherapy or eye tests.
    CONCLUSION: The delivery of complex interventions for a multifactorial condition such as falls in the older persons in our setting is inhibited by various cultural barriers, falls perceptions as well as logistic difficulties. Efforts to establish a multi-disciplinary intervention among our older population will need to include strategies to overcome these issues.

    Inheritance of polymorphisms in the interleukin (IL)-10 promoter and IL-12B genes, which influence cytokine production and activities, may define the balance in T helper response in infection and autoimmune diseases. In the present study, we investigated the distribution of the IL-10 promoter and IL-12B gene polymorphisms in a multiethnic Malaysian population. Overall, our findings suggest that the IL-12B and IL-10 -592 genotypes were distributed homogenously across all major ethnic groups, including Malays, Chinese, and Indians, except for polymorphisms at IL-10 -1082. At this gene locus, the ethnic Chinese showed a significantly lower allele frequency of -1082G (2.1%) compared to the Malay (12.2%) and Indian (15.3%) populations. Results for the IL-12B and IL-10 gene polymorphisms were consistent with those reported for the Asian population, but markedly different from those of the African and Caucasian populations. Our findings suggest that there are specific genetic variations between different ethnic groups, which should be examined in all gene population-based association studies.

  17. Fulltext The development and validation of the Osteoporosis Prevention and Awareness Tool (OPAAT) in Malaysia
    Toh LS, Lai PS, Wu DB, Wong KT, Low BY, Anderson C
    PLoS One, 2015;10(5):e0124553.
    PMID: 25938494 DOI: 10.1371/journal.pone.0124553
    Objectives: To develop and validate Osteoporosis Prevention and Awareness Tool (OPAAT) in Malaysia.
    Methods: The OPAAT was modified from the Malaysian Osteoporosis Knowledge Tool and developed from an exploratory study on patients. Face and content validity was established by an expert panel. The OPAAT consists of 30 items, categorized into three domains. A higher score indicates higher knowledge level. English speaking non-osteoporotic postmenopausal women 50 years of age and pharmacists were included in the study.
    Results: A total of 203 patients and 31 pharmacists were recruited. Factor analysis extracted three domains. Flesch reading ease was 59.2. The mean±SD accuracy rate was 0.60±0.22 (range: 0.26-0.94). The Cronbach’s α for each domain ranged from 0.286-0.748. All items were highly correlated (Spearman’s rho: 0.761-0.990, p<0.05), with no significant change in the overall test-retest scores, indicating that OPAAT has achieved stable reliability. Pharmacists had higher knowledge score than patients (80.9±8.7vs63.6±17.4, p<0.001), indicating
    that the OPAAT was able to discriminate between the knowledge levels of pharmacists and patients.
    Conclusion: The OPAAT was found to be a valid and reliable instrument for assessing patient’s knowledge about osteoporosis and its prevention in Malaysia. The OPAAT can be used to identify individuals in need of osteoporosis educational intervention.

  18. Materialism and life satisfaction: the role of religion
    Rakrachakarn V, Moschis GP, Ong FS, Shannon R
    J Relig Health, 2015 Apr;54(2):413-26.
    PMID: 25811060
    This study examines the role of religion and religiosity in the relationship between materialism and life satisfaction. The findings suggests that religion may be a key factor in understanding differences in findings of previous studies regarding the inverserelationship found in the vast majority of previous studies. Based on a large-scale study in Malaysia—a country comprised of several religious subcultures (mainly Muslims, Buddhists, and Hindus), the findings suggest that the influence of religiosity on materialism and life satisfaction is stronger among Malays than among Chinese and Indians, and life satisfaction partially mediates the relationship between religiosity and materialism. The paper discusses implications for theory development and further research.

  19. Anaemia and iron status among blood donors in a blood transfusion unit in Malaysia
    Nadarajan VS, Eow GI
    Malays J Pathol, 2002 Dec;24(2):99-102.
    PMID: 12887168
    Iron deficiency is a major complication of regular blood donation as a result of regular iron loss from each donated blood unit. Ninety-two regular blood donors and 95 first time blood donors attending a hospital-based blood transfusion centre were assessed as to their haematological and iron status by blood counts and serum ferritin levels as an indicator of iron stores. All donors had passed the haemoglobin-screening test using a copper sulphate method prior to blood donation. Ferritin levels were found to be significantly lower among regular blood donors (47.8 mmol/L) as compared to first time blood donors (94.2 mmol/L). Iron deficiency as observed by low ferritin levels was seen in 7.4% of all first time donors as compared to 17.4% in regular donors. Male first time donors showed a low prevalence of iron deficiency but the prevalence significantly increased with regular blood donation. Female first time and regular blood donors however did not show any significant differences in prevalence of iron deficiency, with both groups exhibiting prevalence rates similar to male regular donors. The association between haemoglobin levels and iron deficiency was poor and the copper sulphate-screening test was found insensitive to anaemia with many donors passing the test and donating blood despite being anaemic. It is concluded that a high prevalence of iron deficiency is present among regular male blood donors and all female donors. Besides, the use of the copper sulphate screening test as a sole criterion for anaemia screening should be reviewed. Ferritin measurements should be included in the routine assessment of blood donors especially among regular blood donors.

    Eur Heart J, 2003 Jan;24(2):151-60.
    PMID: 12573272
    AIMS: We compare the myocardial infarction (MI) event and mortality rates among Chinese, Malay and Indian residents of Singapore.

    METHODS: Residents, aged 20 to 64 years, with an MI event were identified from hospital discharge listings, postmortem reports, and the Registry of Births and Deaths. All pathology laboratories flagged patients with elevated creatine phosphokinase (CPK) levels. Modified MONICA (multinational monitoring of trends and determinants in cardiovascular disease) criteria were used for determining MI events.

    RESULTS: From 1991 to 1999, 12 481 MI events were identified. Chinese patients were older and less likely to have typical symptoms or previous MI. Malays had the highest peak CPK level. Among all three ethnic groups, MI event and age-adjusted case-fatality rates declined. Compared with Chinese, MI event rates were >2-fold and >3-fold higher, and age-standardized coronary mortality rates were 2.4 and 3.0 higher times for Malays and Indians, respectively. Malays have the highest 3.1-year case-fatality, with an adjusted hazard ratio of 1.26 (95% confidence interval, 1.14 to 1.38) compared with Chinese.

    CONCLUSION: We found strong ethnic differences in MI event, case-fatality and coronary mortality rates among the three ethnic groups in Singapore. While Indians have the greatest MI event rates, Malays have the highest case-fatality.
