    PURPOSE: TO DETERMINE: (i) the mammographic parenchymal patterns in Malaysian women and whether the breasts are dense on mammogram; (ii) the effect of age on breast density; (iii) the effect of parity on breast density; (iv) the difference in breast parenchymal patterns among the major races of women in Malaysia.
    METHODS: This was a descriptive cross-sectional study of 1,784 patients (981 Malays, 571 Chinese, 214 Indians and 18 others) who had undergone mammography during the 1-year study period. Majority of women (41.7%) were aged between 51 and 60 years and majority (43%) had 3-4 children. The Tabar classification (Pattern I - V) was used to evaluate breast parenchymal patterns on mammogram. Tabar Pattern I was further divided into 3 sub-groups (Pattern IA, IB, and IC). The different patterns were then grouped into dense (IB, IC, IV, V) and not dense (IA, II, III) breasts. The SPSS package was used for statistical analysis.
    RESULTS: Majority (59%) of Malaysian women had dense breasts (Pattern IB 29%, IC 20%, IV 5%, and V 5%) and 41% did not have dense breasts (Pattern IA 28%, II 6%, and III 7%). Age and parity were inversely related to breast density (p < 0.0001). Chinese women (65.7%) had the highest percentage of dense breasts (p = 0.69, odds ratio = 1.22), followed by the Indians (57.2%) and the Malays (50.5%).
    CONCLUSION: Majority of women had dense breasts but Pattern IV, which has been associated with increased risk of breast cancer, was seen in only 5% of the women. The breast density reduced steadily with increasing age and parity. There was no statistically significant difference in breast density in the three main races.
    KEYWORDS: Mammography; breast density; breast parenchymal patterns

    Globally, the prevalence of diabetes mellitus and the average life expectancy is on the rise. As diabetes mellitus is commonly associated with old age, it is very important to ensure good glucose control to reduce complications and improve quality of life. A cross sectional study was conducted among elderly diabetics in Kulim with the aim to determine the prevalence of glucose control and its associated factors. Three hundred and twenty nine respondents were chosen through stratified random sampling in all the seven health clinics in Kulim. Respondents were interviewed personally using a structured questionnaire. HbA1c level of 6.5% and below was considered as good glucose control. Prevalence of good glucose control was 22.5%. Being male (Adjusted prevalence odds ratio, APOR = 1.75, 95% CI: 1.02-3.00), age of 70 years and above (APOR = 2.48, 95% CI: 1.40-4.39) and duration of diabetes less than five years (APOR = 2.10, 95% CI:1.21-3.64 ) were found to have significant association with good glucose control. As a conclusion, this study showed that the low prevalence of good glucose control was determined by gender, age and duration of illness.

    Introduction : Social problems among adolescents are on the increasing trend. Their involvement in different kinds of high risk behaviours could lead them into juvenile delinquency. Early adolescence is the stage where they are easily influenced. However, this is the period where they should be captured for health prevention enhancement.
    Objectives : A cross-sectional study was carried out to identify factors associated with risk taking behaviours involving form one adolescents in selected secondary schools in Johor Bharu.
    Methods : Using self administered questionnaires, a total of 280 respondents were recruited via multi-stage sampling.
    Results : The prevalence of risk taking behaviour among respondents was 66.8%. Going to video games and karaoke centres was the most popular risk taking behaviour (46.8%) to be followed by truancy (30.7%). Among all the factors studied, being male (AOR=4.5, 95% CI 2.39-8.4), Malay (AOR=7.5, 95% CI 3.30-17.19), and having negative perception towards teachers (AOR 0.3, 95% CI 0.16-0.65) were risk factors for such behaviour among respondents. However, coming from an intact family (AOR=0.1), 95% CI 0.02-0.47) was found to be protective against risk taking behaviour.
    Conclusion : Intact family structure and having positive perception towards teachers were found to be protective against risk taking behaviours among adolescents.

    Smoking among rural adolescents in Malaysia is on the rise with a significant difference seen between urban and rural youths. Therefore, this study was carried out to determine a predictive model of smoking among the rural-school adolescents population in Malacca, Malaysia. An unmatched case-control study was conducted in 2010 involving 484 cases and 444 controls of Form Two students in Malacca, Malaysia, using cluster sampling. Smoking was the dependent factor of this study while the independent factors were individual, family, school and environment. Data were obtained through a self-administered questionnaire. The response rate of the study was 100% whereas the smoking prevalence was 20.9%. Binary logistic regression was used to determine the smoking predictive model. Strong predictors of smoking behaviour were: influenced by artistes who smoke (Adjusted OR=8.67, 95% CI 5.53-13.58); the male gender (Adjusted OR=6.7, 95% CI 4.14-10.83); Muslim (Adjusted OR=4.46, 95% CI 2.36-8.44); and the belief that smoking is not dangerous when the teacher is seen smoking as well (Adjusted OR=3.95, 95% CI 2.19-7.10). Other predictors were: being offered cigarettes by friends (Adjusted OR=2.81, 95% CI 1.79-4.42); the belief that smoking will relax the mind (Adjusted OR=2.45, 95% CI 1.33-4.51); having friends who smoke (Adjusted OR=2.32, 95% CI 1.29-4.81); forced by friends to smoke (Adjusted OR=2.17, 95% CI 1.15-4.12); have heard of the national No-Smoking Campaign (Adjusted OR=1.89, 95% CI 1.06-3.37); have problems with the school management (Adjusted OR=1.75, 95% CI 1.07-2.88); parental consent to watch sexual activities, drug use or violence on television or at the cinema (Adjusted OR=1.73, 95% CI 1.06-2.83); and have lunch in school (Adjusted OR=1.58, 95% CI 1.04-2.41). This paper ends with the recognition of the need for intervention in dismantling the predictors that can lead to the development of smoking among Malaysian adolescents in rural schools. of different pathological entities.

    Depressive illness is common among the aged population. A case control study was conducted, focusing on risk factors influencing depression among the elderly. This study involved 130 elderly patients diagnosed to have depressive illness from the psychiatric clinics of Kuala Lumpur Hospital (HKL) and Universiti Kebangsaan Malaysia Hospital (HUKM). Another group of 130 elderly patients with no history of depressive illness were recruited from the medical specialist clinics. The majority of cases were female (75.4%), aged 60-74 years (92.3%) and from Chinese ethnic group (59.2%). Non-Malay elderly has three times risk (AOR 2.537, 95% CI 1.439-4.471) of suffering the depressive illness compared to the Malay elderly, the elderly with chronic health problems are more likely to be depressed compared to those who do not suffer from any chronic illness (p trend <0.001). Other risk factors identified were family history of depression with four times risk (AOR 4.225, 95% CI 2.017-8.848) and lower social support with eight times risk (AOR 7.949, 95% CI 2.588-24.417). Social support is not only important in encouraging the elderly to practice healthy life style but proven to influence the risk of getting depression among them. Hence, it is very crucial that the elderly is given total attention, respect and love from all parties to ensure prosperity and meaningfulness in life.

    Introduction: Anemia in pregnancy is still a public health problem in developing countries including Malaysia. Early screening of pregnant mothers who have risk factors of anemia could help identifying these potential anemic mothers and hence targeted for intervention.
    Methodology: A cross sectional study IN 2008 was conducted among pregnant women who attended government health clinics in Johor Bahru district to assess the prevalence of anemia in pregnancy and factors associated with it using a structured questionnaire.
    Result: Prevalence of anemia in pregnancy (Hb<11.0 g/dl) was 36.6% and majority in mild category (Hb 9-<11 g/dl). The associated factors of anemia in pregnancy were birth spacing, dietary intake with high iron content and iron pill consumption. Multivariate analyses revealed that iron pill intake was the most important factor influencing anemia in pregnancy.
    Discussion and conclusion: Even though Johor Bahru is a big town with good health facilities, the prevalence of anemia in pregnancy was quite high. Results were compared with previous studies. Emphasis on compliance to iron pills is very important in prevention and treating anemia in pregnancy
    Key Words: anemia in pregnancy, birth spacing and iron pill intake

    Giardia duodenalis causes diarrhoea and malabsorption. The objectives of the study were to detect local isolates of G. doudenalis by polymerase chain reaction (PCR) and to determine their restriction fragment length polymorphisms (RFLP). G. doudenalis isolated from stools of patients from Hospital Orang Asli Gombak were cultured axenically using TYI-S-33 medium with 10% foetal calf serum. The commercially designed primer-pair 432/433 was used to amplify a 0.52 kb segment known to encode the homologous cysteine-rich trophozoite surface antigen (tsp11 and tsa417). Results showed that the primer-pair 432/433 could amplify the target region of the local isolates. RFLP study on the identical isolates showed that all the restriction enzymes tested ( HindIII, ClaI, PstI and Kpn) gave a banding pattern similar to that of the WB strain a reference pathogenic strain from human. The reference pathogenic strain were commercially obtained from the American Type Culture Collection (ATCC).

    Giardia duodenalis is an intestinal parasite that causes diarrhoea and malabsorption in children. The parasite also infects AIDS patients with a weak immune system. A study was carried out on six local isolates of Giardia duodenalis (110, 7304, 6304, M007, 2002 and 6307) from faeces of Orang Asli patients admitted to the Gombak Hospital. WB, a reference pathogenic strain from human and G. muris from a wild mouse, were commercially obtained from the American Type Culture Collection (ATCC). All the isolates were cultured axenically in TYI-S-33 medium. Two sets of primers were used for the techniques: primers LP1 and RP1 and primers LP2 and RP2. The sets of primers amplified giardine gene of 171 bp and 218 bp in sizes respectively. The study showed that the two sets of primers could detect G. duodenalis to the genus and species level specifically.

    AIM: Simulators for aortic dissection diagnosis are limited by complex anatomy influencing the accuracy of point-of-care ultrasound for diagnosing aortic dissection. Therefore, this study aimed to create a healthy ascending aorta and class DeBakey, type II aortic dissection simulator as a potential point-of-care ultrasound training model.

    MATERIAL AND METHODS: 3D mould simulators were created based on computed tomography images of one healthy and one DeBakey type II aortic dissection patient. In the next step, two polyvinyl alcohol-based and two silicone-based simulators were synthesised.

    RESULTS: The results of the scanning electron microscope assessment showed an aortic dissection simulator's surface with disorganised surface texture and higher root mean square (RMS or Rq) value than the healthy model of polyvinyl alcohol (RqAD = 20.28 > RqAAo = 10.26) and silicone (RqAD = 33.8 > RqAAo = 23.07). The ultrasound assessment of diameter aortic dissection showed higher than the healthy ascending aorta in polyvinyl alcohol (dAD = 28.2 mm > dAAo = 20.2 mm) and Si (dAD = 31.0 mm > dAAo = 22.4 mm), while the wall thickness of aortic dissection showed thinner than the healthy aorta in polyvinyl alcohol, which is comparable with the actual aorta measurement. The intimal flap of aortic dissection was able to replicate and showed a false lumen in the ultrasound images. The flap was measured quantitatively, indicating that the intimal flap was hyperechoic.

    CONCLUSIONS: The simulators were able to replicate the surface morphology and echogenicity of the intimal flap, which is a linear hyperechoic area representing the separation of the aorta wall.

    In the field of hybrid natural fiber polymer composites, there has been a recent surge in research and innovation for structural applications. To expand the strengths and applications of this category of materials, significant effort was put into improving their mechanical properties. Hybridization is a designed technique for fiber-reinforced composite materials that involves combining two or more fibers of different groups within a single matrix to manipulate the desired properties. They may be made from a mix of natural and synthetic fibers, synthetic and synthetic fibers, or natural fiber and carbonaceous materials. Owing to their diverse properties, hybrid natural fiber composite materials are manufactured from a variety of materials, including rubber, elastomer, metal, ceramics, glasses, and plants, which come in composite, sandwich laminate, lattice, and segmented shapes. Hybrid composites have a wide range of uses, including in aerospace interiors, naval, civil building, industrial, and sporting goods. This study intends to provide a summary of the factors that contribute to natural fiber-reinforced polymer composites' mechanical and structural failure as well as overview the details and developments that have been achieved with the composites.
