    A cross-sectional study was carried out to determine the knowledge and practices of 425 female secondary school teachers from 20 selected secondary schools in Selangor, Malaysia on breast cancer screening (BCS). A self-administered, structured questionnaire was used for data collection. This study showed moderate to low knowledge on breast cancer (BC) and BCS among teachers. Only 19%, 25% and 13.6% eligible women performed breast self-examination (BSE), clinical breast examination (CBE) and mammography respectively, on a regular basis. Level of breast cancer knowledge was significantly associated with BSE (p<0.001). Having heard/ read about BCS, and regular visit with a physician were associated with BCS behaviors (P<0.05). There was no association between BCS behaviors (P>0.05) and age, family history of breast cancer, marital status or having health insurance. Efforts are needed to increase knowledge and remove misconceptions about breast cancer and screening practices among Malaysian women.

    The association between fetal sex and outcome of pregnancy and labor has been well documented in western populations. However, no studies in Malaysia or other developing countries have examined the effect of fetal sex on such outcomes.The main objective of this study was to determine the influence of fetal sex on the outcome of labor at term in a cohort of Malaysian nulliparae.A retrospective observational study was designed using data from 4644 Malaysian nulliparae who gave birth consecutively to singleton male babies at Hospital Sultanah Aminah, Johor Bahru, after normal full-term pregnancies.The results of this study indicate that mothers giving birth to male infants have a greater risk of requiring cesarean delivery because male babies are heavier and have statistically significantly greater head circumference (P < .001). These findings concur with those obtained in western populations and suggest that the differences in outcome observed are biological, not dictated by race, ethnicity, or environmental conditions. Such information could help in the antenatal assessment of Malaysian patients and stimulate more comprehensive studies of the mechanisms involved in this sex-based difference in outcomes. Reasons for such differences are proposed.

    OATP1B1 is a liver-specific transporter that mediates the uptake of various endogenous and exogenous compounds including many clinically used drugs from blood into hepatocytes. This study aims to identify genetic variations of SLCO1B1 gene in three distinct ethnic groups of the Singaporean population (n=288). The coding region of the gene encoding the transporter protein was screened for genetic variations in the study population by denaturing high-performance liquid chromatography and DNA sequencing. Twenty-five genetic variations of SLCO1B1, including 10 novel ones, were found: 13 in the coding exons (9 nonsynonymous and 4 synonymous variations), 6 in the introns, and 6 in the 3' untranslated region. Four novel nonsynonymous variations: 633A>G (Ile211Met), 875C>T (Ala292Val), 1837T>C (Cys613Arg), and 1877T>A (Leu626Stop) were detected as heterozygotes. Among the novel nonsynonymous variations, 633A>G, 1837T>C, and 1877T>A were predicted to be functionally significant. These data would provide fundamental and useful information for pharmacogenetic studies on drugs that are substrates of OATP1B1 in Asians.

    Endothelial function is impaired in healthy subjects at risk of type 2 diabetes mellitus (DM). We investigated whether endothelial dysfunction can be normalized by statin therapy in this potentially predisposed population. Flow-mediated dilation (FMD) was measured in 56 first-degree relatives (FDRs) (normotensive, normal glucose tolerance) and 20 age-, sex-, and BMI-matched controls with no family history of DM. Other measurements included insulin resistance index using the homeostasis model of insulin resistance (HOMA(IR)), plasma lipids, and markers of inflammation. The FDRs were then randomized and treated with atorvastatin (80 mg) or placebo daily in a 4-week double-blind, placebo-controlled trial. The FDRs had significantly impaired FMD (4.4 +/- 8.1% vs. 13.0 +/- 4.2%; P < 0.001), higher HOMA(IR) (1.72 +/- 1.45 vs. 1.25 +/- 0.43; P = 0.002), and elevated levels of plasma markers of inflammation-highly sensitive C-reactive protein (hsCRP) (2.6 +/- 3.8 mg/L vs. 0.7 +/- 1.0 mg/L; P = 0.06), interleukin (IL)-6 (0.07 +/- 0.13 ng/mL vs. 0.03 +/- 0.01 ng/mL; P < 0.001), and soluble intercellular adhesion molecule (sICAM) (267.7 +/- 30.7 ng/mL vs. 238.2 +/- 20.4 ng/mL; P < 0.001). FMD improved in the atorvastatin-treated subjects when compared with the placebo-treated subjects (atorvastatin, from 3.7 +/- 8.5% to 9.8 +/- 7.3%; placebo, from 3.9 +/- 5.6% to 4.7 +/- 4.2%; P = 0.001). There were also reductions in the levels of IL-6 (0.08 +/- 0.02 ng/mL vs. 0.04 +/- 0.01 ng/mL; P < 0.001) and hsCRP (3.0 +/- 3.9 mg/L vs. 1.0 +/- 1.3 mg/L; P = 0.006). Our study suggests that treatment with atorvastatin may improve endothelial function and decrease levels of inflammatory markers in FDRs of type 2 DM patients.

    The purpose of this study was to investigate the association between pregnancy-induced hypertension and low birth weight. A population-based case control study was conducted. Antenatal mothers who attended the government health centers in the district of Kuala Muda, Kedah, Malaysia from June 2003 to May 2004 were recruited. Cases were 312 mothers who delivered low birth weight babies, and controls were 312 mothers who delivered normal birth weight babies. Face-to-face interviews using a structured questionnaire and a review of medical records were carried out. After controlling for important confounders such as gestational age at delivery, maternal age, ethnicity, education, parity, and previous history of abortion, pregnancy-induced hypertension was found to be an independent risk factor (adjusted odds ratio = 5.06; 95% confidence interval: 2.63, 9.71) for low birth weight. There was a significant association of pregnancy-induced hypertension with low birth weight. Women who delivered low birth weight babies were 5 times more likely to have had pregnancy-induced hypertension.

    Despite being an emergent major public health problem, little research has been done on domestic violence from the perspectives of early detection and prevention. Thus, this cross-sectional study was conducted to identify domestic violence among female adult patients attending health centers at the primary care level and to determine the relationship between social correlates of adult patients and domestic violence screening and subsequent help/health-seeking behavior if abused. Face-to-face interviews were conducted with 710 female adult patients from 8 health centers in Selangor who matched the inclusion criteria and consented to participate in the study, using a structured questionnaire that included adaptation of a validated 8-item Women Abuse Screening Tool (WAST). Statistical tests showed significant differences in ethnicity, income, and education between those screened positive and those screened negative for domestic violence. Of the participants, 92.4% reported that during consultations, doctors had never asked them whether they were abused by their husband/partner. Yet, 67.3% said they would voluntarily tell the doctor if they were abused by their husband/partner. The findings indicate that primary care has an important role in identifying domestic violence by applying the WAST screening tool, or an appropriate adaptation, with women patients during routine visits to the various health centers. Such assessment for abuse could be secondary prevention for the abused women, but more important, it will serve as primary prevention for nonabused women. This approach not only will complement the existing 1-stop crisis center policy by the Ministry of Health that copes with crisis intervention but also will spearhead efforts toward prevention of domestic violence in Malaysia.

    Nasopharyngeal carcinoma (NPC) and other head and neck cancer (HNCA) types show a great epidemiological variation in different regions of the world. NPC has multifactorial etiology and many interacting risk factors are involved in NPC development mainly Epstein Barr virus (EBV). There is a need to scrutinize the complicated network of risk factors affecting NPC and how far they are different from that of other HNCA types.

    Crinum asiaticum Linne var. japonicum has long been used as a rheumatic remedy, as an anti-pyretic and as an anti-ulcer treatment, and for the alleviation of local pain and fever in Korea and Malaysia. In order to investigate the possibility of Crinum asiaticum Linne var. japonicum extract as a cosmetic ingredient, we measured its anti-inflammatory effect by its inhibition of iNOS (inducible nitric oxide synthase) and the release of PGE2, IL-6, and IL-8. We also measured its anti-allergic effect by its inhibition of beta-hexosamidase release. An HPLC experiment after extraction with 95% EtOH at pH 3.5 showed that Crinum asiaticum Linne var. japonicum was mainly composed of lycorine (up to 1%), a well-known immunosuppressor. The content of lycorine varied, depending on the type of plant tissue analyzed and the extraction method. In an anti-inflammatory assay for inhibition of nitric oxide formation on lipopolysaccharide (LPS)-activated mouse macrophage RAW 264.7 cells, the ethanol extract of Crinum asiaticum showed an inhibitory activity of NO production in a dose-dependent manner (IC50 = 58.5 microg/ml). Additional study by RT-PCR demonstrated that the extract of Crinum asiaticum significantly suppressed the expression of the iNOS gene. Moreover, the extract of Crinum asiaticum did not show any cytotoxicity, but did show a cell proliferation effect against LPS (a 10 approximately 60% increase in cell viability). In an assay to determine inhibition of the H2O2-activated release of PGE2, IL-6, and IL-8 in human normal fibroblast cell lines, the release of PGE2 and IL-6 was almost completely inhibited above concentrations of 0.05% and 1%, respectively. Moreover, the release of IL-8 was completely inhibited over the entire range of concentration (>0.0025%). In order to investigate the skin-sensitizing potentials of the extract of Crinum asiaticum, a human clinical test was performed after repeated epicutaneous 48-h applications under an occlusive patch (RIPT). The repeated and single cutaneous applications of Crinum asiaticum Linne var. japonicum extract under the occlusive patch did not provoke any cumulative irritation and sensitization reactions. The result showed that the extract of Crinum asiaticum Linne var. japonicum has a sufficient anti-inflammatory effect. Therefore, Crinum asiaticum Linne var. japonicum extract may be useful for development as an ingredient in cosmetic products.

    Parasuicide has become an increasingly common response to emotional distress in young adults. The general pattern of parasuicide shows variations among the developing countries. The objectives of this study were to determine the pattern of parasuicide and suicide beside comparing the characteristics between different ethnic groups. The study was a retrospective case review of all parasuicide cases treated in Hospital Sungai Bakap and all suicides from the hospital mortuary from January 2001 to December 2005. We collected data concerning demographic data, information on method used and the circumstances. A total of 189 cases of parasuicide were analysed. There was a significant increase of parasuicide from 26.5 per 100,000 persons in 2001 to 32.1 per 100,000 persons in 2005. Seventy two percent of the cases were female. Indians constituted 64 % of the cases, followed by the Chinese (19 %), Malays (13 %) and foreigners (4 %). The age group 18-30 years ranked at the top, constituting 59.7% of the cases. Majority of the cases were by intentional poisoning and only 2 cases (1.1 %) were intentional injuries by sharp objects. In the past 5 years, the agents implicated were drugs (43.9 %), pesticides (23.5 %), household products (11.8 %), and others (20.8 %). Intentional Paracetamol poisoning had doubled from 11.7 % in 2001 to 23.4 % in 2005 while the use of pesticides had decreased from 32 % in 2001 to 17 % in 2005. Only 2 % of the cases had history of underlying disorders like schizophrenia and personalities disorders. As for suicide, the rates remained relatively unchanged at 5 per 100,000 populations. In this study, the demographic characteristics of suicide differ from parasuicide as suicides were associated with higher percentage of males and Chinese. There were 2 peaks in the age group of 31-40 and above 60 years old. The highest mode of suicide was hanging (53.5 %), followed by pesticide poisoning (25.6 %) and inhaled carbon monoxide (9.3 %).There is a need to improve on prevention and interventions for parasuicide and decrease suicide prevalence.

    Since the early 1990s, the Malaysian government has identified factories as high risk for HIV and AIDS. Signaling epidemiological concerns over the rising rates of HIV among factory workers, a significant proportion of whom are women, the label also appeared to reconstitute stereotypes of factory women as dangerously sexual and of factories as immoral spaces. Drawing on ethnographic research in the export processing zones of Penang, Malaysia in the mid-1990s, I examine the meanings and experiences of HIV risk among factory women themselves. Data were analyzed using discourse and grounded theory methods, the former to identify women's multiple modes of rationalizing HIV risks, and the latter to theorize the sources and significance of women's HIV risk assemblages. The heuristic of assemblages as localized knowledge spaces helped to show that biomedical and socioreligious risk lexica operated not as fixed epistemological categories but as situational resources in women's risk scripts. Overall, women desired multiple risk knowledges to help them "control themselves by themselves," a project of reflexive self-shaping mediated by the diverse and discordant discourses of gender, ethnicity, and modernity in Malaysia that shaped how HIV risks were engendered and experienced.

    BACKGROUND AND OBJECTIVES: There is lack of published data on bulbar signs among the healthy population. This study aims to determine the range of normality of bulbar signs particularly among the elderly.

    METHODS: Systemic examination of bulbar signs was carried out according to a predetermined protocol on a cohort of young and elderly healthy subjects.

    RESULTS: A total of 206 subjects were recruited in the study, 104 young adults with mean age of 20 years, and 102 elderly with mean age of 73 years. Uvula deviation was seen in 28 (26.9%) young subjects and 22 (21.6%) elderly. Irregular tongue border was seen in 17 subjects, unilateral in 4 subjects. Fourteen (6.8%) subjects had deviation on tongue protrusion. Occasional tremor of tongue on protrusion is common in both young and old. Persistent (severe) tongue tremor on protrusion was seen in 18.6% of the elderly, and 4.8% of the young. None of the subjects had tremor of tongue at rest. In gag reflex, absence of gagging response was common in elderly, seen in two thirds of the subjects on stimulation of the posterior pharyngeal wall. However, all the subjects had uvular movement. Habituation or suppression of gagging response was seen in close to 90% of young males.

    CONCLUSION: There is wide range of normality in bulbar signs in normal population, particularly among the elderly.

    Renal hyperparathyroidism with attendant osteodystrophy is a frequent and severe morbidity affecting the quality of life of end stage renal failure patients surviving on long-term renal replacement therapy. A small subgroup of these patients with severe cardiorespiratory dysfunction was deemed at very high risk for general anaesthesia (GA). We report on a series of total parathyroidectomy under local anaesthesia (LA) for these patients.

    We determined the differential expression levels of proteins in peripheral blood mononuclear cells of patients with dengue fever (DF) and dengue hemorrhagic fever (DHF). Proteins were subjected to two-dimensional electrophoresis, mass spectrometry and Western blot analysis. We identified 8 proteins that were 2-fold or more up-regulated in patients compared to healthy control, three of which, aldolase, thioredoxin peroxidase and alpha tubulin, were related to dengue infection. Both thioredoxin peroxidase and alpha tubulin were over-expressed 4.9 and 3.3 times respectively in DHF compared to DF patients while aldolase was up-regulated 2.2 times in DF compared to DHF patients. Alpha tubulin and thioredoxin peroxidase have the potential to be utilized as biomarkers for DHF.

    OBJECTIVES: The aims of this study were to characterize the population frequency of PEPT2 (SLC15A2) polymorphic variants in three Asian ethnic populations, namely Chinese, Malay and Asian Indian, and to investigate the associations of ethnicity (Chinese vs. Asian Indian), PEPT2 haplotype and cephalexin pharmacokinetics in healthy Asian subjects.

    METHODS: PEPT2 polymorphisms were screened from a cohort of 96 Chinese, 96 Malay and 96 Asian Indian subjects. Cephalexin (1000 mg, orally) pharmacokinetics was characterized in an additional 15 Chinese and 15 Asian Indian healthy subjects. These 30 subjects were subsequently genotyped for their PEPT2 polymorphisms.

    RESULTS: In total, ten common single nucleotide polymorphisms (SNPs) were detected in the three populations, forming two PEPT2 haplotypes. There were significant ethnic differences in PEPT2 haplotype distribution: the frequencies of the *1 and *2 alleles were 0.307 and 0.693 in the Chinese population, 0.495 and 0.505 in the Malay population and 0.729 and 0.271 in Asian Indian population, respectively. The C (max) of cephalexin was significantly lower in the Chinese (29.80 +/- 4.09 microg ml(-1)) population than in the Asian Indian one (33.29 +/- 4.97 microg ml(-1); P = 0.045). This difference could be explained by the higher average body weight of the Chinese population. There was no other significant difference in cephalexin pharmacokinetics between either ethnic or PEPT2 genotype groups.

    CONCLUSION: PEPT2 polymorphism distributions differ significantly between Chinese, Malay and Asian Indian populations. However, cephalexin pharmacokinetics is not meaningfully different between Chinese and Asian Indians. The association between the PEPT2 haplotype and cephalexin pharmacokinetics could not be confirmed, and future studies under better controlled conditions are needed.

    Hair nicotine is a known biomarker for monitoring long-term environmental tobacco smoke (ETS) exposure and smoking status. In general, hair nicotine assay involves alkaline digestion, extraction and instrumental analysis. The gas chromatography-mass spectrometry (GC-MS) assay currently developed has shown to be of high throughput with average approximately 100 hair samples being extracted and analyzed per day. This was achieved through simplified extraction procedure and shortened GC analysis time. The extraction was improved by using small volume (0.4 mL) of organic solvent that does not require further evaporation and salting steps prior to GC-MS analysis. Furthermore, the amount of hair utilized in the extraction was very little (5 mg) while the sensitivity and selectivity of the assay is equal, if not better than other established methods. The linearity of the assay (r(2)>0.995), limit of quantitation (0.04 ng/mg hair), within- and between-assays accuracies and precisions (<11.4%) and mean recovery (92.6%) were within the acceptable range.
