Case-control investigation on the risk factors of melioidosis in small ruminant farms in Peninsular Malaysia

Musa HI, Hassan L, Shamsuddin ZH, Panchadcharam C, Zakaria Z, Abdul Aziz S, et al.

J Appl Microbiol, 2015 Aug;119(2):331-41.
PMID: 25891038 DOI: 10.1111/jam.12830

Epidemiology of melioidosis is poorly understood because its occurrence is influenced by complex interaction of environmental, climatic, physicochemical and host factors. We investigated the potential risk factors for the exposure to Burkholderia pseudomallei in small ruminants' farms in Peninsular Malaysia.

Fulltext Association between PDCD1 gene polymorphisms and risk of systemic lupus erythematosus in three main ethnic groups of the Malaysian population

Chua KH, Lian LH, Sim XJ, Cheah TE, Lau TP

Int J Mol Sci, 2015;16(5):9794-803.
PMID: 25938972 DOI: 10.3390/ijms16059794

The programmed cell death 1 (PDCD1) gene encodes for the PD-1 (programmed death 1) molecule, which negatively regulates self-reactive T- and B-cells in the maintenance of peripheral tolerance. A previous report had shown the development of lupus-like phenotypes in PD-1-deficient C57BL/6 mice, was suggestive to the role of PDCD1 in predisposing to systemic lupus erythematosus (SLE). Hence, we aimed to investigate the association between PDCD1 and SLE susceptibility in the Malaysian population. A TaqMan-based real-time PCR was employed to screen for PD1.1, PD1.3, PD1.5 and PD1.6 in both SLE and healthy control groups of 200 samples each. The observed frequency for PD1.5C/C genotype was significantly higher in Indian SLE patients and Malay controls (p < 0.01). On the other hand, the PD1.5C/T genotype might predispose the Malays to SLE, but confer a protective effect among the Indians (p < 0.01). The PD1.1, PD1.3 and PD1.6 were, however, not correlated to genetic predisposition of SLE in our Malaysian population. In conclusion, PD1.5 variant was significantly associated to SLE susceptibility in our Malaysian cohort. Our failure in replicating the association between other investigated PDCD1 variants and risk of getting SLE might due to ethnic and geographic variations in the distribution of these genetic variants.

Fulltext Impact of smoking and smoking cessation on cardiovascular events and mortality among older adults: meta-analysis of individual participant data from prospective cohort studies of the CHANCES consortium

Mons U, Müezzinler A, Gellert C, Schöttker B, Abnet CC, Bobak M, et al.

BMJ, 2015 Apr 20;350:h1551.
PMID: 25896935 DOI: 10.1136/bmj.h1551

OBJECTIVE: To investigate the impact of smoking and smoking cessation on cardiovascular mortality, acute coronary events, and stroke events in people aged 60 and older, and to calculate and report risk advancement periods for cardiovascular mortality in addition to traditional epidemiological relative risk measures.
DESIGN: Individual participant meta-analysis using data from 25 cohorts participating in the CHANCES consortium. Data were harmonised, analysed separately employing Cox proportional hazard regression models, and combined by meta-analysis.
RESULTS: Overall, 503,905 participants aged 60 and older were included in this study, of whom 37,952 died from cardiovascular disease. Random effects meta-analysis of the association of smoking status with cardiovascular mortality yielded a summary hazard ratio of 2.07 (95% CI 1.82 to 2.36) for current smokers and 1.37 (1.25 to 1.49) for former smokers compared with never smokers. Corresponding summary estimates for risk advancement periods were 5.50 years (4.25 to 6.75) for current smokers and 2.16 years (1.38 to 2.39) for former smokers. The excess risk in smokers increased with cigarette consumption in a dose-response manner, and decreased continuously with time since smoking cessation in former smokers. Relative risk estimates for acute coronary events and for stroke events were somewhat lower than for cardiovascular mortality, but patterns were similar.
CONCLUSIONS: Our study corroborates and expands evidence from previous studies in showing that smoking is a strong independent risk factor of cardiovascular events and mortality even at older age, advancing cardiovascular mortality by more than five years, and demonstrating that smoking cessation in these age groups is still beneficial in reducing the excess risk.

Fulltext Can Saliva Proteins Be Used to Predict the Onset of Acute Myocardial Infarction among High-Risk Patients?

Rahim MA, Rahim ZH, Ahmad WA, Hashim OH

Int J Med Sci, 2015;12(4):329-35.
PMID: 25897294 DOI: 10.7150/ijms.11280

Human saliva plays a pivotal role in digesting food and maintaining oral hygiene. The presence of electrolytes, mucus, glycoproteins, enzymes, antibacterial compounds, and gingival crevicular fluid in saliva ensures the optimum condition of oral cavity and general health condition. Saliva collection has been proven non-invasive, convenient, and inexpensive compared to conventional venipuncture procedure. These distinctive advantages provide a promising potential of saliva as a diagnostic fluid. Through comprehensive analysis, an array of salivary proteins and peptides may be beneficial as biomarkers in oral and systemic diseases. In this review, we discuss the utility of human salivary proteomes and tabulate the recent salivary biomarkers found in subjects with acute myocardial infarction as well as respective methods employed. In a clinical setting, since acute myocardial infarction contributes to large cases of mortality worldwide, an early intervention using these biomarkers will provide an effective solution to reduce global heart attack incidence particularly among its high-risk group of type-2 diabetes mellitus patients. The utility of salivary biomarkers will make the prediction of this cardiac event possible due to its reliability hence improve the quality of life of the patients. Current challenges in saliva collection are also addressed to improve the quality of saliva samples and produce robust biomarkers for future use in clinical applications.

Association of BDNF Polymorphisms with the Risk of Epilepsy: a Multicenter Study

Sha'ari HM, Haerian BS, Baum L, Tan HJ, Rafia MH, Kwan P, et al.

Mol Neurobiol, 2016 07;53(5):2869-2877.
PMID: 25876511 DOI: 10.1007/s12035-015-9150-1

Epilepsy is a common neurological disease characterized by recurrent unprovoked seizures. Evidence suggested that abnormal activity of brain-derived neurotrophic factor (BDNF) contributes to the pathogenesis of epilepsy. Some previous studies identified association between genetic variants of BDNF and risk of epilepsy. In this study, this association has been examined in the Hong Kong and Malaysian epilepsy cohorts. Genomic DNA of 6047 subjects (1640 patients with epilepsy and 4407 healthy individuals) was genotyped for rs6265, rs11030104, rs7103411, and rs7127507 polymorphisms by using Sequenom MassArray and Illumina HumanHap 610-Quad or 550-Duo BeadChip arrays techniques. Results showed significant association between rs6265 T, rs7103411 C, and rs7127507 T and cryptgenic epilepsy risk (p = 0.00003, p = 0.0002, and p = 0.002, respectively) or between rs6265 and rs7103411 and symptomatic epilepsy risk in Malaysian Indians (TT vs. CC, p = 0.004 and T vs. C, p = 0.0002, respectively) as well as between rs6265 T and risk of cryptogenic epilepsy in Malaysian Chinese (p = 0.005). The Trs6265-Crs7103411-Trs7127507 was significantly associated with cryptogenic epilepsy in Malaysian Indians (p = 0.00005). In conclusion, our results suggest that BDNF polymorphisms might contribute to the risk of epilepsy in Malaysian Indians and Chinese.

Risk assessment and microbiological profile of infections in paediatric cancer patients with febrile neutropenia

Latiff Z, Zulkifli SZ, Jamal R

Malays J Pathol, 2002 Dec;24(2):83-9.
PMID: 12887165

Febrile neutropenia is a common and potentially fatal problem encountered in cancer patients undergoing chemotherapy. We carried out an observational study to evaluate the possible risk factors of developing fever amongst neutropenic children with an underlying malignancy. We also looked at the microbiological profile of causative pathogens in patients with febrile neutropenia. During a study period of 1 year, a total of 90 neutropenic episodes were recorded amongst 57 patients who were on treatment and follow-up during the study period. Multivariate analysis showed that factors such as chemotherapy status, underlying disease, existing central venous catheters, presenting white blood cell counts at chemotherapy, use of steroid therapy or hospitalisation at the onset of neutropenia, were not significant risk factors for developing fever during neutropenic episodes. Although the presence of a central venous catheter was associated with a higher risk of developing fever, it did not reach statistical significance (p=0.11). Of the 90 neutropenic episodes, 59 (65.6%) developed fever and 25 of these had positive blood cultures. The causative organisms include gram-negative bacteria (64%), gram positive bacteria (16%) and fungus (20%). Of the gram-negative organisms, Klebsiella spp. predominated (28%) with the extended spectrum beta-lactamase producing strain forming the majority (16%). Amongst those with fungaemia, Candida spp. and Candida tropicalis formed the majority (8% each) of the isolates.

Fulltext Prevention of type 2 diabetes

Lai LC

Malays J Pathol, 2002 Dec;24(2):71-6.
PMID: 12887163

The prevalence of diabetes is increasing worldwide. The World Health Organisation has estimated that there will be around 300 million diabetics by 2025. The largest increase will occur in Asia. The prevalence of type 2 diabetes is increasing due to a combination of factors: increasing lifespan, sedentary lifestyle, excessive intake of high energy foods, increasing prevalence of overweight/obese people. The Finnish Diabetes Prevention Study Group has clearly shown that changes in the lifestyle of both overweight men and women with impaired glucose tolerance can reduce the incidence of type 2 diabetes by 58%. This finding was confirmed by the Diabetes Prevention Programme which found that lifestyle intervention in individuals with impaired fasting glucose or impaired glucose tolerance reduced the risk of developing type 2 diabetes by 58%, whereas treatment with metformin reduced the risk of type 2 diabetes by only 31%. Both acarbose and troglitazone have also been shown to reduce the progression to diabetes in individuals who are at high risk of developing type 2 diabetes. Since the cure for diabetes remains some way off our concerted efforts should be directed at prevention of diabetes in order to curb the increasing prevalence of diabetes worldwide. Lifestyle changes are more beneficial than long term drug therapy in the prevention of diabetes and should be actively promoted.

Cardiovascular epidemiology in the Asia-Pacific region

Khor GL

Asia Pac J Clin Nutr, 2001;10(2):76-80.
PMID: 11710361

By 2020, non-communicable diseases including cardiovascular diseases (CVD) are expected to account for seven out of every 10 deaths in the developing countries compared with less than half this value today. As a proportion of total deaths from all-causes, CVD in the Asia Pacific region ranges from less than 20% in countries such as Thailand, Philippines and Indonesia to 20-30% in urban China, Hong Kong, Japan, Korea and Malaysia. Countries such as New Zealand, Australia and Singapore have relatively high rates that exceed 30-35%. The latter countries also rank high for coronary heart disease (CHD) mortality rate (more than 150 deaths per 100,000). In contrast, death from cerebrovascular disease is higher among East Asian countries including Japan, China and Taiwan (more than 100 per 100,000). It is worth noting that a number of countries in the region with high proportions of deaths from CVD have undergone marked declining rates in recent decades. For example, in Australia, between 1986 and 1996, mortality from CHD in men and women aged 30-69 years declined by 46 and 51%, respectively. In Japan. stroke mortality dropped from a high level of 150 per 100,000 during the 1920s-1940s to the present level of approximately 100 per 100,000. Nonetheless, CVD mortality rate is reportedly on the rise in several countries in the region, including urban China, Malaysia, Korea and Taiwan. In China, CVD mortality increased as a proportion of total deaths from 12.8% in 1957 to 35.8% in 1990. The region is undergoing a rapid pace of urbanization, industrialization and major technological and lifestyle changes. Thus, monitoring the impact of these changes on cardiovascular risks is essential to enable the implementation of appropriate strategies towards countering the rise of CVD mortality.

Fulltext Risk factors for hip fracture in Asian men and women: the Asian osteoporosis study

Lau EM, Suriwongpaisal P, Lee JK, Das De S, Festin MR, Saw SM, et al.

J. Bone Miner. Res., 2001 Mar;16(3):572-80.
PMID: 11277276 DOI: 10.1359/jbmr.2001.16.3.572

The objectives of the Asian Osteoporosis Study (AOS) were to determine risk factors for hip fracture in men and women in four Asian countries, that is, Singapore, Malaysia, Thailand, and the Philippines. A total of 451 men and 725 women (aged 50 years and over) with hip fractures were compared with an equal number of community controls. A standardized questionnaire was administered by interview. The following relative risks (RRs) were found in women and men by multiple logistic regression: dietary calcium intake < 498 mg/day, 2.0 for women (95% CI, 1.5-2.8) and 1.5 for men (95% CI, 1.0-2.2); no load bearing activity in the immediate past, 2.0 for women (95% CI, 1.4-2.7) and 3.4 for men (95% CI, 2.3-5.1); no vigorous sport activities in young adulthood, 7.2 for women (95% CI, 4.0-13.0) and 2.4 for men (95% CI, 1.6-3.6); cigarette smoking, 1.5 for men (95% CI, 1.0-2.1); alcohol consumption 7 days a week, 2.9 for women (95% CI, 1.0-8.6) and 1.9 for men (95% CI, 1.1-3.2); fell twice or more in the last 12 months, 3.0 for women (95% CI, 1.8-4.8) and 3.4 for men (95% CI, 1.8-6.6); a history of fractures after 50 years of age, 1.8 for women (95% CI, 1.1-2.9) and 3.0 for men (95% CI, 1.6-5.6); a history of stroke, 3.8 for women (95% CI, 2.0-7.1) and 3.6 for men (95% CI, 1.8-7.1); use of sedatives, 2.5 for women (95% CI, 1.0-6.3) and 3.0 for men (95% CI, 1.0-9.7); and use of thyroid drugs, 7.1 for women (95% CI, 2.0-25.9) and 11.8 for men (95% CI, 1.3-106.0). Women who were 1.56 m or taller had an RR of 2.0 (95% CI, 1.3-3.0) for hip fracture and men who were 1.69 m or taller had an RR of 1.9 (95% CI, 1.2-3.1) for hip fracture. Based on these findings, primary preventive programs for hip fracture could be planned in Asia.

Where is Malaysia in the midst of the Asian epidemic of diabetes mellitus?

Zaini A

Diabetes Res Clin Pract, 2000 Oct;50 Suppl 2:S23-8.

Population studies all over the world have clearly showed that the prevalence of Type 2 diabetes mellitus (DM) is escalating at phenomenal scale and very likely we are heading towards epidemic proportions. In 1985, the estimated population of diabetic individuals in the world was 30 million but by 1995 this figure soared to 135 million. Based on current trends, epidemiologists predict that the population of diabetic individuals will swell up to a staggering 300 million by the year 2025. Almost half of that will be in the Asia Oceania region alone. Dr Hilary King of WHO pointed out that there will be a projected rise of about 42% in developed countries whereas the developing countries will see an escalation to the magnitude of 170% (H. King, R.E. Aubert, W.H. Herman, Global burden of diabetes, 1995-2025: prevalence, numerical estimates and projections, Diabetes Care 21 (1998) 1414-1431; WHO Health Report 1997, WHO Switzerland). There will be a 3-fold rise of the disease in Asia and much of these will be seen in China (40 million) and India (55 million) by virtue of the massive population of these countries. Nevertheless, the other rapidly developing Asian nations like Singapore, Malaysia, Thailand and those making up Indochina will experience the surge. At the same time the prevalence and incidence of diabetes complications will also increase. Based on recent WHO prediction (WHO Newsletter, The global burden of diabetes 1995-2025. World Diabetes 3 (1997) 5-6), it is estimated that by the year 2000 the following figures will be seen:Diabetes complications are major causes of premature death all over the world and most of these are avoidable. DCCT and UKPDS are landmark studies showing strong evidence that major complications can be drastically reduced by maintaining to near normoglycaemic control.

Ethnicity, obstructive sleep apnoea and ischaemic heart disease

Tan YK, Khoo KL, Low JA, Wong ZW, Theng CT, Ong TH, et al.

Ann Acad Med Singap, 1999 Mar;28(2):214-6.
PMID: 10497669

We studied the relationship between different ethnic groups, obstructive sleep apnoea (OSA) and ischaemic heart disease. Four hundred and thirty-two inpatients from the medical wards were interviewed. Limited overnight sleep studies were done in 129 of those who had habitual snoring, daytime sleepiness based on an Epworth sleepiness scale of 8 or more, or a large neck size of 40 cm or more. There were 315 Chinese (72.9%), 67 Malays (15.5%), 43 Indians (10%) and 3 from other races (1.4%). The prevalence of OSA was 19.7%, 30% and 12% among the Chinese, Malays and Indians, respectively. The prevalence ratio for OSA was 1.52 in Malays using Chinese patients as the baseline (P = 0.07). The median neck circumference was 37 cm in both racial groups. The median body mass index was 22.7 kg/m2 in Chinese compared to 23.6 kg/m2 in Malays. The median apnoea-hypopnoea index was 22.7, 19.0 and 26.9 events/hour among the Chinese, Malays and Indians, respectively. OSA was independently associated with the prevalence of IHD (adjusted prevalence ratio 1.68; 95% CI: 1.15, 2.46; P = 0.009). The prevalence of ischaemic heart disease (IHD) was 31%, 24% and 28% in Chinese, Malays and Indians, respectively. The prevalence ratio for IHD in Malays compared to Chinese was 0.77. After adjusting for OSA, there was an even greater reduction in the risk of IHD (adjusted prevalence ratio 0.70). This suggests that OSA is a confounder in the relationship between race and ischaemic heart disease.

Epidemiology of erectile dysfunction in four countries: cross-national study of the prevalence and correlates of erectile dysfunction

Nicolosi A, Moreira ED, Shirai M, Bin Mohd Tambi MI, Glasser DB

Urology, 2003 Jan;61(1):201-6.
PMID: 12559296 DOI: 10.1016/s0090-4295(02)02102-7

OBJECTIVES:
To measure the prevalence of erectile dysfunction (ED) in community-based populations in Brazil, Italy, Japan, and Malaysia and to study its association with the demographic characteristics, medical conditions, and health-related behavior.

METHODS:
In each country, a random sample of approximately 600 men aged 40 to 70 years was interviewed using a standardized questionnaire. All the data were self-reported. ED was assessed by the participants' "ability to attain and maintain an erection satisfactory for sexual intercourse," and the men were classified as not having ED if they answered "always" and as having mild, moderate, or complete ED if they answered "usually," "sometimes," or "never," respectively.

RESULTS:
The age-adjusted prevalence of moderate or complete ED was 34% in Japan, 22% in Malaysia, 17% in Italy, and 15% in Brazil. The overall age-specific prevalence of moderate or complete ED was 9% for men aged 40 to 44 years, 12% for 45 to 49 years, 18% for 50 to 54 years, 29% for 55 to 59 years, 38% for 60 to 64 years, and 54% for those 65 to 70 years. The increased risk of ED was associated with diabetes, heart disease, lower urinary tract symptoms, heavy smoking, and depression and increased by 10% per year of age. It was inversely associated with education, physical activity, and alcohol drinking.

CONCLUSIONS:
ED is an international problem, the prevalence and severity of which increases with age. Despite national variations in prevalence, uniform associations were found between ED and medical conditions and lifestyle habits.

Development of a screening tool for detecting undernutrition and dietary inadequacy among rural elderly in Malaysia: simple indices to identify individuals at high risk

Shahar S, Dixon RA, Earland J

Int J Food Sci Nutr, 1999 Nov;50(6):435-44.
PMID: 10719584

Undernutrition and the consumption of poor diets are prevalent among elderly people in developing countries. Recognising the importance of the early identification of individuals at high nutritional risk, this study aimed to develop a simple tool for screening. A cross-sectional study was conducted on 11 randomly selected villages among the 62 in Mersing District, Malaysia. Undernutrition was assessed using body mass index, plasma albumin and haemoglobin on 285 subjects. Dietary inadequacy (a count of nutrients falling below two-thirds of the Recommended Dietary Allowances) was examined for 337 subjects. Logistic regression analysis was performed to identify significant predictors of undernutrition and dietary inadequacy from social and health factors, and to derive appropriate indices based on these predictions. The multivariate predictors of undernutrition were 'no joint disease', 'smoker', 'no hypertension', 'depended on others for economic resource', 'respiratory disease', 'perceived weight loss' and 'chewing difficulty', with a joint sensitivity of 56% and specificity of 84%. The equivalent predictors of dietary inadequacy were 'unable to take public transport', 'loss of appetite', 'chewing difficulty', 'no regular fruit intake' and 'regularly taking less than three meals per day', with a joint sensitivity of 77% and specificity of 47%. These predictions, with minor modification to simplify operational use, led to the production of a simple screening tool. The tool can be used by public health professionals or community workers or leaders as a simple and rapid instrument to screen individual at high risk of undernutrition and/or dietary inadequacy.

Comparison of parenting stress between Malaysian mothers of four-year-old very low birthweight and normal birthweight children

Ong LC, Chandran V, Boo NY

Acta Paediatr, 2001 Dec;90(12):1464-9.
PMID: 11853347 DOI: 10.1080/08035250152708905

A study was carried out to compare parenting stress between 116 mothers of very low birthweight (VLBW) children and 96 mothers of normal birthweight (NBW) children at 4 y of age, using the Parenting Stress Index (PSI). Multiple regression analysis was used to determine factors associated with child-domain stress (CDS) and parent-domain stress (PDS). There was a significantly higher proportion (39.7%) of mothers of VLBW children with high CDS scores >90th percentile than mothers of NBW children (20.8%). No significant differences were observed for PDS scores. Lower intelligence quotient (IQ) scores and adverse child behaviour, as evidenced by higher Child Behavior Checklist (CBCL) scores, were significantly associated with higher CDS scores (p < 0.001). Factors associated with higher PDS scores were higher CBCL scores (p < 0.001), mothers who were the primary caregivers (p < 0.001), male sex (p = 0.018) and lower level of maternal education (p = 0.048). These factors remained statistically significant even when physically and cognitively impaired children were excluded from the analysis.

CONCLUSION: Specific child characteristics and the social environment appear to have a greater impact on parenting stress than the biological risk of VLBW birth per se.

Risk factors associated with neonatal hypothermia during cleaning of newborn infants in labour rooms

Cheah FC, Boo NY

J Trop Pediatr, 2000 Feb;46(1):46-50.
PMID: 10730042

Cleaning newborn infants with coconut oil shortly after birth is a common practice in Malaysian labour rooms. This study aimed: (1) to determine whether this practice was associated with a significant decrease in the core temperature of infants; and (2) to identify significant risk factors associated with neonatal hypothermia. The core temperature of 227 randomly selected normal-term infants immediately before and after cleaning in labour rooms was measured with an infrared tympanic thermometer inserted into their left ears. Their mean post-cleaning body temperature (36.6 degrees C, SD = 1.0) was significantly lower than their mean pre-cleaning temperature (37.1 degrees C, SD = 1.0; p < 0.001). Logistic regression analysis showed that the risk factors significantly associated with pre-cleaning hypothermia (< 36.5 degrees C) were: (1) not being placed under radiant warmer before cleaning p = 0.03); and (2) lower labour room temperature (p < 0.001). Logistic regression analysis also showed that the risk factors significantly associated with post-cleaning hypothermia were: (1) lower labour room temperature (p < 0.001); (2) lower pre-cleaning body temperature (p < 0.001); and (3) longer duration of cleaning (p = 0.002). In conclusion, to prevent neonatal hypothermia, labour room temperature should be set at a higher level and cleaning infants in the labour room should be discouraged.

Seroprevalence of Helicobacter pylori infection in Malaysian children: evidence for ethnic differences in childhood

Boey CC, Goh KL, Lee WS, Parasakthi N

J Paediatr Child Health, 1999 Apr;35(2):151-2.
PMID: 10365351

OBJECTIVES: To determine the prevalence of Helicobacter pylori (H. pylori) in healthy Malaysian children and to discover whether differences exist among children of different races.
METHODS: Serum samples from asymptomatic children tested for H. pylori seropositivity using an ELISA test.
RESULTS: Five hundred and fourteen healthy urban Malaysian children aged 0.5 to 17 (mean 5.9) years from three different racial groups had their blood tested for H. pylori antibodies. The overall prevalence was 10.3%. There was no significant difference in the prevalence of infection between boys and girls, but a significant rise was noted with increasing age (P = 0.009). Seropositivity was most common in the Indians and lowest in the Malays (P = 0.001). Father's level of education did not affect the child's rate of H. pylori seropositivity.
CONCLUSION: The prevalence of H. pylori seropositivity among asymptomatic urban Malaysian children is lowest in Malays. Intermediate in Chinese and highest in Indians. The racial differences found in children are consistent with those found in Malaysian adults.

Stroke patterns in Northeast Malaysia: a hospital-based prospective study

Jaya F, Win MN, Abdullah MR, Abdullah MR, Abdullah JM

Neuroepidemiology, 2002 Jan-Feb;21(1):28-35.
PMID: 11744823

All patients with a first-ever stroke admitted to the HUSM (Hospital Universiti Sains Malaysia) from 1997 to 1998 were included in this study. All risk factors were determined and analysed prospectively. There were 158 cases of stroke admitted during the study period. The majority of the patients were Malays (86.1%), with a male preponderance. The mean age (SD) of the patients with stroke was 59.3 (12.28) years. Hypertension was present in both cerebral infarct and intracerebral haemorrhage patients at almost the same rate (65.2 and 69.2%, respectively). The overall mortality was 37%, and most patients died in the 1st month after stroke (34%). We hope this study will highlight the problems associated with the presentation and management of stroke in Southeast Asia.
