    PMID: 9707784
    This survey was undertaken to study the clinical features of trigeminal neuralgia in an Asian population. Demographic data of 44 patients treated at the Dental Faculty of the National University of Singapore and at the University of Malaya were reviewed. The results of the survey were analysed and comparisons made with those of Caucasian patients as reported in other studies where there was a general similarity in the clinical findings. Trigeminal neuralgia presented predominantly in females. Right-sided involvement occurred at a greater frequency, and the peak age at onset was between the sixth and seventh decades of life. The only significant variant in the present sample was the greater involvement of the mandibular branch of the trigeminal nerve rather than the maxillary division. In addition, there was a much greater representation from Chinese patients over Malays as compared with their ratios in the general population.

    PMID: 15272740
    We reviewed various studies regarding human toxoplasmosis in Malaysia. They showed a varying prevalence of specific Toxoplasma antibodies among the Malaysian population. The Malays have shown the highest seroprevalence of toxoplasmosis, by most studies, when compared to other races. Demographic profiles have shown that Toxoplasma seropositivity is higher in males than females, lower in people with higher incomes, higher in the unemployed and tends to increase with age. In general, the route of transmission, such as contact with a cat, consumption of undercooked meat and blood transfusion were shown to have no significant association with Toxoplasma seropositivity (p > 0.05). The immune status (CD4 cell count < 200 cell/mm3) was strongly associated with toxoplasmic encephalitis (p < 0.05).

    PMID: 15243197
    This report provides a comprehensive analysis of gender differences in economic support and well-being in eight countries in Southern and Eastern Asia (Bangladesh, Malaysia, Indonesia, Singapore, Thailand, Vietnam, Philippines, and Taiwan). We examine multiple economic indicators, including sources of income, receipt of financial and material support, income levels, ownership of assets, and subjective well-being. Results show substantial variation in gender differences across indicators and provide an important qualification to widely held views concerning the globally disadvantaged position of older women. Whereas men tend to report higher levels of income than women, there is generally little gender difference in housing characteristics, asset ownership, or reports of subjective economic well-being. Unmarried women are economically advantaged compared to unmarried men in some respects, in part because they are more likely to be embedded in multigenerational households and receive both direct and indirect forms of support from family members.

  5. A pilot study of reference vibrotactile perception thresholds on the fingertip obtained with Malaysian healthy people using ISO 13091-1 equipment
    Daud R, Maeda S, Kameel NN, Ripin MY, Bakrun N, Md Zein R, et al.

    PMID: 15128168
    The purpose of this paper is to clarify the reference vibrotactile perception thresholds (VPT) for healthy people in Malaysia. The measurement equipment standard, ISO 13091-1, of the vibrotactile perception thresholds for the assessment of nerve dysfunction and the analysis and interpretation of measurements at the fingertips standard, ISO 13091-2, were published in ISO/TC108/SC4/WG8 on 2001 and 2003 individually. In the ISO 13091-2 standard, the reference VPT data were obtained from few research papers. Malaysian people's VPT data don't include to this standard. In Malaysia, when the VPT is using to diagnose of the hand-arm vibration syndrome, the reference VPT data need to compare with the worker's ones. But, Malaysia does not have the reference VPT data yet. So, in this paper, the VPT was measured by using ISO 13091-1 standard equipment to obtain the reference data for Malaysian people. And these data were compared with the ISO reference data on the ISO 13091-2 standard. From the comparison of these data, it was clear that the Malaysian healthy people's VPT data were consistent with the reference data of the ISO 13091-2 standard.

  6. Fulltext The outcome of abdominal aortic aneurysm repair in northern Malaysia
    Lakhwani MN, Yeoh KCB, Gooi BH, Lim SK
    Med J Malaysia, 2003 Aug;58(3):420-8.
    PMID: 14750383
    A prospective study of all infrarenal abdominal aortic aneurysm (AAA) repairs both as electives and emergencies in Penang between January 1997 to December 2000 is presented. The objectives of the study were to determine the age, gender, racial distribution of the patients, the incidence, and risk factors and to summarize treatments undertaken and discuss the outcome. Among the races, the Malays were the most common presenting with infrarenal AAA. The mean age of patients operated was 68.5 years. Males were more commonly affected compared to females (12:1). Most infrarenal AAA repairs were performed as emergency operations, 33 cases (61.1%) compared to electives, 21 cases (38.9%). Total survival was 70.3% (elective 85.7%; emergency 57.6%). Mortality rate was 31.5% and the primary reason is the lack of operating time available for urgent operation and for treatment of concurrent disease states. Mycotic aneurysm with its triad of abdominal pain, fever and abdominal mass resulted in a significantly higher mortality (46.6%). Ninety six percent of the infrarenal AAA had transverse diameter greater than 6 cm. Morphologically 90.7% were fusiform AAA rather than saccular aneurysm (9.3%). Pulmonary complications (35.2%) were more common than cardiac complications (11.1%) possibly related to the urgent nature of the operation, smoking or history of pulmonary tuberculosis. Bleeding (14.8%) was the most common cause of mortality in ruptured mycotic infrarenal AAA.

  7. Tobacco control and gender in south-east Asia. Part II: Singapore and Vietnam
    Morrow M, Barraclough S
    Health Promot Int, 2003 Dec;18(4):373-80.
    PMID: 14695368
    In the World Health Organization's Western Pacific Region, being born male is the single greatest risk marker for tobacco use. While the literature demonstrates that risks associated with tobacco use may vary according to sex, gender refers to the socially determined roles and responsibilities of men and women, who initiate, continue and quit using tobacco for complex and often different reasons. Cigarette advertising frequently appeals to gender roles. Yet tobacco control policy tends to be gender-blind. Using a broad, gender-sensitivity framework, this contradiction is explored in four Western Pacific countries. Part I of the study presented the rationale, methodology and design of the study, discussed issues surrounding gender and tobacco, and analysed developments in Malaysia and the Philippines (see the previous issue of this journal). Part II deals with Singapore and Vietnam. In all four countries gender was salient for the initiation and maintenance of smoking. Yet, with a few exceptions, gender was largely unrecognized in control policy. Suggestions for overcoming this weakness in order to enhance tobacco control are made.

  8. Fulltext Do Singapore patients require lower doses of statins? The SGH Lipid Clinic experience
    Tan CE, Loh LM, Tai ES
    Singapore Med J, 2003 Dec;44(12):635-8.
    PMID: 14770258
    A substantial number of physicians in Asian countries believe that Asian patients need lower doses of statins to achieve therapeutic lipid target because of the smaller size of patients. This belief is deep rooted and we looked at the SGH Lipid Clinic to determine if our experience bears out this belief. Between 1996 and August 2000, the Lipid Unit treated a total of 841 patients, of which 548 patients (77.5% Chinese, 12.1% Malays, 7.6% Asian Indians; 49.6% males, 50.4% females; 54.7% diabetics, 45.3% non-diabetic) were on statins alone. These patients had > or =2 coronary risk factors, diabetes mellitus or documented coronary heart disease. The pre-treatment lipid levels or the worst lipid levels available were entered as the baseline lipid values (mean LDL-C: 5.38+1.5 mmol/l). Duration of therapy ranged from six months to five years. The choice and titration of statins were determined by attending physicians. The median statin dose (Simvastatin equivalent) was 20.0 mg with 52.5% requiring 20 mg or more. Statin dose did not differ between diabetic and non-diabetic subjects. The median statin dose was 15 mg for the lower two tertiles and 20 mg for the upper tertile; this difference did not achieve statistical significance. The reduction in LDL cholesterol was 41.5% (40.1-42.8) and total cholesterol was 33.0% (32.9-34.1). Only 25% of our patients achieved LDL cholesterol of less than 2.6 mmol/l whilst 77.5% had LDL cholesterol less than 3.4 mmol/l. Our experience at the Lipid Clinic suggests that the Asian patients require similar statin doses to achieve target cholesterol levels.

  9. Fulltext Seroprevalence of human parvovirus B19 infection in an urban population in Malaysia
    Ooi SL, Hooi PS, Chua BH, Lam SK, Chua KB
    Med J Malaysia, 2002 Mar;57(1):97-103.
    PMID: 14569725 MyJurnal
    A seroepidemiological study carried out on 800 stored serum samples collected between January 1999 to December 2000 derived from an urban population in Malaysia showed that the overall seropositive rate of human paravovirus B19 infection was 37.6%, with an overall geometric mean titre (GMT) of 18.3 IU. The seropositive rates of B19 among the male and female populations were 39.0% and 36.3% respectively. The seropositive rates among the racial groups were 37.2%, 38.2%, 38.1% and 29.4% respectively for the Malays, Chinese, Indians and other races. There was no statistical significant gender and racial differences in the B19 seropositive rates. When compared with the seroprevalence of B19 infection in other Asian countries, the seropositive rate of B19 in Malaysia was low in the younger age group and increased steadily with age. The unusual finding in this study was the presence of a high seropositive rate in those between six months to five years of age, especially in children in the one year old age group.

  10. Medication use and adherence among multi-ethnic community-dwelling older adults in Malaysia
    Neoh CF, Long CM, Lim SM, Ramasamy K, Shahar S, Majeed ABA
    Geriatr Gerontol Int, 2017 Aug;17(8):1214-1220.
    PMID: 27489036 DOI: 10.1111/ggi.12849
    AIM: The present study assessed adherence, barriers, belief and awareness towards the use of medications among multi-ethnic community-dwelling older adults in Malaysia. Medication accessibility, expenditure and perceptions towards medicine labeling among older adults were also evaluated.

    METHODS: A cross-sectional study was carried out in the central region of Malaysia from January to August 2015. The older adults enrolled in an ongoing prospective community-based geriatric cohort study and prescribed with medicines were interviewed using a 50-item validated questionnaire.

    RESULTS: Of the 79 older adults interviewed, 39.2% had ≥4 prescribed medications. Most obtained their medications free-of-charge from government hospitals (66, 83.5%). Nearly half (35, 44.3%) had trouble reading labels for medicines that they had received. Chinese older adults (P = 0.001) and those with lower monthly household income (P

  11. Uncovering the sleep disorders among young doctors
    Yasin R, Muntham D, Chirakalwasan N
    Sleep Breath, 2016 Dec;20(4):1137-1144.
    PMID: 27535070 DOI: 10.1007/s11325-016-1380-6
    PURPOSE: Sleepiness and tiredness are common complaints among young doctors. Sleep deprivation is believed to be the main culprit. However, we believe that there may be other sleep disorders which may contribute to these symptoms such as occult obstructive sleep apnea (OSA).

    METHODS: A prospective cross-sectional study was performed among young doctors less than 40 years old, working at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, and Hospital Kuala Lumpur, Kuala Lumpur, Malaysia, using questionnaires and home sleep apnea testing (Apnealink™Plus). The primary objective of this study was to evaluate the prevalence of OSA (apnea-hypopnea index (AHI) ≥5). The secondary objectives were to evaluate the prevalence of obstructive sleep apnea syndrome (OSAS) defined by AHI ≥5 + excessive daytime sleepiness (EDS), sleep deprivation (the difference of weekend (non-workdays) and weekday (workdays) wake-up time of at least 2 h), EDS (Epworth Sleepiness Scale score ≥10), tiredness, and perception of inadequate sleep as well as to identify their predictors.

    RESULTS: Total of 52 subjects completed the study. Mean age and mean body mass index (BMI) were 31.3 ± 4 and 23.3 ± 3.6, respectively. The prevalence of OSA and OSAS were 40.4 and 5.8 %, respectively. One third of OSA subjects were at least moderate OSA. Prevalence of sleep deprivation, EDS, tiredness, and perception of inadequate sleep were 44.2, 15.4, 65.4, and 61.5 %, respectively. History of snoring, being male, and perception of inadequate sleep were significant predictors for OSA with the odds ratio of 34.5 (p = 0.016, 95 % CI = 1.92-619.15), 18.8 (p = 0.001, 95 % CI = 3.10-113.41), and 7.4 (p = 0.037, 95 % CI = 1.13-48.30), respectively. Only observed apnea was a significant predictor for OSAS with odds ratio of 30.7 (p = 0.012, 95 % CI = 2.12-442.6). Number of naps per week was a significant predictor for EDS with the odds ratio of 1.78 (p = 0.007, 95 % CI = 1.17-2.71). OSA and total number of call days per month were significant predictors for tiredness with the odds ratio of 4.8 (p = 0.036, 95 % CI = 1.11-20.72) and 1.3 (p = 0.050, 95 % CI = 1.0004-1.61), respectively. OSA was the only significant predictor for perception of inadequate sleep with the odd ratios of 4.5 (p = 0.022, 95 % CI = 1.24-16.59).

    CONCLUSIONS: Our results demonstrated relatively high prevalence of OSA and OSAS among young doctors. Snoring, being male, and perception of inadequate sleep were significant predictors for OSA. Observed apnea was a significant predictor for OSAS. OSA was a significant predictor for tiredness and perception of inadequate sleep.

  12. Observations on some epidemiological aspects of toxoplasmosis in Malaysia
    Saleha AA
    Int J Zoonoses, 1984 Jun;11(1):75-83.
    PMID: 6389404
    A review of the various studies on toxoplasmosis in peninsular Malaysia is presented. The period of review spanned between 1973 and 1980 during which a number of serological surveys were carried out for the presence of Toxoplasma gondii antibody in Malaysians, using either the indirect hemagglutination (I.H.A.) or the indirect fluorescent antibody (I.F.A.) tests. The prevalence rates of Toxoplasma antibody were consistently foundhighest among Malays, followed by Indians, Orang Aslis (Aborigines) and lowest among Malays, followed by Indians, Orang Aslia (Aborigines) and lowest among Chinese, the 4 major ethnic groups living in Malaysia. Positive titres, present in all age groups, showed an increase with age but no difference due to sex. However, higher prevalence of positive cases was recorded among rural dwellers and the lower socioeconomic group than from urban dwellers. The possible routes of infection among the ethnic groups were discussed. Among animal populations, the presence of Toxoplasma antibody was detected in buffaloes, swine, goats, cattle, cats and dogs. The epidemiological importance of the findings are discussed and suggestions made for future studies.

    PMID: 6743148
    Blood samples were collected from 24 immature male, 55 immature female and 99 mature female water buffalo kept at an experimental farm in the Northern Territory. Haematological analysis was performed on blood collected in dipotassium--ethylene diamine tetra acetic acid while biochemical analysis was performed on serum and plasma (for glucose) samples. Haematological values of mature buffalo were similar to those recorded for swamp buffalo in Malaysia. Blood cell appearances were similar to those reported for adult Indian river buffalo though values recorded for red cell components were higher. Statistical analysis revealed no significant differences between immature male and female buffalo. Red cell components, eosinophils, total plasma and serum proteins, albumin, gamma globulins, inorganic phosphate and the enzyme gamma-glutamyl transferase were significantly higher for mature female buffalo when compared to immature females. Reasons for the differences were not fully determined but the effect of age and nutritional status in combination with a variable period of domestication were considered.

  16. Alphaviruses in Peninsular Malaysia: II. Serological evidence of human infection
    Marchette NJ, Rudnick A, Garcia R
    Southeast Asian J Trop Med Public Health, 1980 Mar;11(1):14-23.
    PMID: 7403943
    A serum survey of several characteristic groups of humans in urban, rural, and forested areas of Peninsular Malaysia for evidence of infection with three alphaviruses (Sindbis, getah, and chikungunya) was made on 4384 specimens collected between 1965 and 1969. Analysis of the serological results indicated that 1) persons residing in predominantly rural and forested areas have higher frequencies of specific alphavirus antibody of all three viruses than persons residing in urban areas, 2) human infection with chikungunya virus appears to be at a low level of activity but is widespread, although more common and recent in the northern part of the country, and 3) Sindbis and getah viruses probably do not represent a threat to the public health, but chikungunya virus remains a potential menance and may be responsible for future epidemics transmitted by A. aegypti and A. albopictus mosquitoes.

    PMID: 6105712
    The first major Malaysian epidemic of dengue hemorrhagic fever with severe manifestations occurred in 1973, with 969 reported cases and 54 deaths. In a detailed study of 138 clinically diagnosed and laboratory confirmed cases at the General Hospital in Kuala Lumpur, hemorrhagic manifestations were observed in 68.7% and shock in 18.1% of the patients. The cases occurred mainly from May to September, largely in urban and suburban areas of the majority of the states in the country. A main focus of infection was Jinjang, a heavily populated outlying district of Kuala Lumpur, where unusually high incidences of morbidity, severe disease and mortality were seen. Severe disease was seen mostly in children under the age of 15 years, although a significant number of adults suffered milder illnesses. The Chinese population was chiefly affected, due to their living in crowded, low-income housing where the vector, Aedes aegypti, occurred in the greatest numbers. All four dengue types were recovered during the epidemic period, although dengue 3 (DEN-3) was incriminated as the major epidemic type. Entomological data revealed high indices of A. aegypti throughout the country and left little doubt that this epidemic was aegypti transmitted. Spraying and fogging operations were carried out in attempts to control vector populations.

  18. Fulltext A serological study of cytomegalovirus and herpes simplex virus infections in Peninsular Malaysia
    Tan DS, Stern H
    Bull World Health Organ, 1981;59(6):909-12.
    PMID: 6279323
    Healthy Malaysians from various parts of Peninsular Malaysia were examined for CF antibodies against cytomegalovirus (CMV) and herpes simplex virus (HSV) type 2. CMV antibodies were detected in 1114 out of 1556 persons (71.6%) and HSV antibodies were detected in 954 persons out of 1554 (61.4%). The age distribution patterns were similar for the two infections, with maximum prevalence at 5 - 14 years of age. Prevalence was higher in women than in men. There were no significant differences among the Malay, Chinese, and Indian groups of the population with respect to CMV, 72 - 78% possessing antibodies, but in the case of HSV, 76% of the Chinese had antibodies, compared with 57 - 60% of the Malays and Indians. More than 90% of newborn infants had CMV and HSV CF antibodies, confirming the highly immune status of childbearing women in Malaysia. No CMV-specific IgM was detected in the Malaysian neonates examined but this does not exclude the possibility of congenital infection.

  19. Changing sex ratio of mortality in the Semai Senoi, 1969-1987
    Fix AG
    Hum Biol, 1991 Apr;63(2):211-20.
    PMID: 2019414
    An excess of male over female deaths is characteristic of modern national populations, whereas in some high-mortality societies female mortality exceeds that of males. Among the Semai Senoi, a Malaysian Orang Asli ("aboriginal") population, women experienced higher mortality than males in the decades before 1969. This differential occurred in all age classes older than 15 years so that the sex ratio progressively increased with age. A recent (1987) restudy of the Semai population found that sex-specific differential mortality is much reduced. A comparison of the 1969 and 1987 life tables shows a sharp shift in the sex ratios of mortality for the post-15-year-old age classes (the geometric means of age classes 15-44 were 0.768 in 1969 and 0.997 in 1987) so that male and female expectations of further life at age 15 are now nearly identical. In contrast to the best-known cases of high female mortality (mostly in South Asia), Semai sex differential mortality does not include the childhood ages. The Semai have traditionally been relatively sexually egalitarian, and sex bias in care has not occurred. Analysis of sex-specific causes of death for the pre-1969 population suggests that maternal mortality is the major cause of the excess female deaths. The reduced number of maternal deaths seems largely due to better health care, particularly the availability of hospital services. Interestingly, the reduction in female mortality has occurred simultaneously with increased fertility, and overall mortality has continued at relatively high levels (eO less than 36). Thus, rather than forming a component of a unitary demographic transition, declining sex differences in mortality can be accounted for by a specific factor, better maternal care.

  20. Fulltext Side effects of short course tuberculosis chemotherapy
    Simon GK, Lye MS, Ahmad N
    Med J Malaysia, 1991 Mar;46(1):88-94.
    PMID: 1836044
    A retrospective study of 300 tuberculosis patients on short course chemotherapy registered in 1985 at the Chest Clinic, General Hospital Alor Setar, Kedah was carried out with the purpose of identifying patient characteristics, determining incidence of side-effects and modifying treatment regimens in order to minimise these side-effects. One hundred and sixteen (38.7%) patients developed side effects. Twenty seven (9%) had side effects severe enough to warrant a change in treatment regimen. Treatment modifications and ways to minimise or control side effects are discussed.
