    The incidence of hepatocellular carcinoma (HCC) in Malaysia for the year 2001 was 2.8 per 100,000 people. The mortality rate is increasing. A retrospective cohort study measuring the survival of HCC patients who received treatment in Selayang Hospital was conducted from 1 January 2003 to 31 December 2006. The main objectives of the study were to measure the survival of the patients and to understand the influencing factors, especially ethnicity. The subjects were newly diagnosed cases of HCC by CT scan and histopathological assessment who underwent futher investigations and treatments in Hospital Selayang (inception cohort). The survival time was measured from the date of diagnosis until the subjects died, or failed to follow-up at the end of the study period (31 December 2007). A total of 299 patients were selected with 95 patients dying, the majority among Chinese (39.1%). Subgroup analysis according to ethnicity proved significantly that Chinese patients who had smaller tumor, less number of nodules, low AFP level, Child Pugh Class A and received surgical treatment had a better median survival rate compared to other ethnic groups. Malay (cHR: 1.3, 95%CI; 0.89-1.85) and Indian (cHR: 1.3, 95%CI; 0.74-2.26) patients had a poor survival compared to Chinese patients, but not in the final model. Therefore ethnicity may play a role in survival of HCC patients, but not as a main hazard prognostic factor.

    Ebola virus disease (EVD), Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), rabies and Nipah infections were examples of diseases that were related to bats and shook the world with a series of outbreak and epidemic. Through the understanding of bats as potential public health risk, awareness had become vital to prevent another outbreak. This pilot study was done to evaluate the appropriateness of the questionnaires and to determine preliminary data on knowledge, attitude and practices of bats-related infections. Residents of a village were recruited by randomly choosing houses from a list obtained from the local head village. Knowledge, attitude and practice were assessed using a 56-items questionnaire. The study recruited 100 respondents. The questionnaire’s Cronbach Alpha score was 0.817. Majority of the respondents were found to have good knowledge (71%), attitude (99%) and practice (64%) relating to bat-related infection. There was a weak positive correlation between knowledge and practice towards bat-related infections among residents of the study population. Majority (80%) of respondents did not aware that bats can cause rabies, and 84% did not know about rabies vaccination. The result of this pilot study provides a limited but valuable insight into bat-related infection. Overall, respondents had good knowledge, attitude and practice scores towards bats-related infection. However, more awareness is needed to key areas lacking such as in educating awareness about rabies in bats.

    INTRODUCTION: Lung cancer is the most commonly diagnosed cancer worldwide and is the leading cause of cancer death. Smoking is a major contributor to the pathogenesis of lung cancer. Cytochrome P450 2A6 (CYP2A6) is responsible for the metabolic activation of most tobacco carcinogens. CYP2A6 genetic polymorphism can cause variations in the human metabolism of xenobiotics. We performed this meta-analysis to determine the association between whole-gene CYP2A6 deletion polymorphism (CYP2A6*4) and lung cancer risk.

    METHODS: The PubMed, SAGE, Science Direct, the Cochrane Library and Ovid databases were searched for observational studies before October 2018. Methodological quality was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS).

    RESULTS: Nine case-control studies involving 4385 lung cancer cases and 4142 controls were included in the analysis. The random-effects model was used to combine results from individual studies. The pooled odds ratio was 0.39 (95% CI: 0.27-0.56). There was no heterogeneity across studies (χ2=2.49, p=0.96, I2=0%).

    CONCLUSIONS: Current evidence from the case-control studies suggests that the CYP2A6 whole-gene deletion polymorphism decreases the risk of lung cancer. Further research is needed to identify any potential confounding factors that may impact this association.

    INTRODUCTION: Adolescents' involvement in sexual practices are becoming a major public health concern in Malaysia. This study aims to determine the prevalence of sexual practices among Malaysian school-going adolescents and its predictive factors.

    METHODS: A cross-sectional study was carried out from April 2012 till September 2012 among 16-year-old school adolescents from two different schools. They were selected through simple random sampling and these adolescents answered a self-administered questionnaire consisting of three sections i.e. socio-demography, risk-taking behaviours and family-adolescents relationship. Data were analysed using Pearson Chi-Square test while Simple Logistic Regression and Multiple Logistic Regression were applied to determine the predictive factors.

    RESULTS: The prevalence of sexual practices among the adolescents was 30.1% in which they were either involved in pornography (26.8%), pre-sexual activities (8.5%) or premarital sex (2.9%). Six predictive factors associated with sexual practices among this age group were identified which were male (adjusted Odds Ratio (aOR) 2.7, 95% Confidence Interval (95%CI) 1.4 to 2.5), truancy (aOR 2.3, 95%CI 1.3 to 4.2), bully (aOR 3.5, 95%CI 1.7 to 7.3), hanging out (aOR 2.8, 95% 1.4 to 5.6), staying out late (aOR 3.2, 95%CI 1.5 to 6.8) and conflict with family (aOR 4.1, 95%CI 1.9 to 8.9).

    DISCUSSION: Asian background differs from the western countries and findings of this study may suggest suitable intervention programmes that can prevent high-risk sexual practices among Asian school-going adolescents.

    BACKGROUND: The practice of modern contraceptives still remains a sceptical issue in the society and dormant due to increasing objection of husbands who play a significant role in the family planning practice.
    OBJECTIVES: This study was done to determine the factors affecting the ever use of modern contraceptive methods among married men visiting a healthcare clinic in Malaysia.
    MATERIAL AND METHOD: A cross sectional study of 443 men aged over 18 years was conducted using convenient sampling from January 2016 till March 2016 at a primary care clinic. A self-administered questionnaire assessing sociodemographic characteristic, attitude towards family planning, spousal communication and ever used of modern contraceptive methods was used.
    RESULTS: The proportion of ever used modern contraception was 48% (n=192). Multiple logistic regression revealed that spousal communication on family planning (Adjusted OR 15.8; 95% CI 7.0 - 35.6) and attitude towards marital relationship (Adjusted OR 1.1; CI 1.0 - 1.1) were significant predictors for ever used of modern contraception among married men.
    CONCLUSION: The proportion of ever used modern contraception is still not high. Men who communicated with their spouse on modern contraception and perceived family planning as means to preserve their marital relationship were more likely to practice modern contraceptive method.

    INTRODUCTION: Lower limb cellulitis is a common superficial skin infection that leads to morbidity and mortality. Cellulitis risk factors have been well studied in many countries, but to date, not in Malaysia. Geographical and climate variables may affect risk factors. Early identification of the preventable risk factors is vital to prevent cellulitis and improve holistic patient care.

    OBJECTIVE: To determine the risk factors of lower limb cellulitis amongst hospitalized patients at a tertiary center.

    METHODS: A prospective case-control study of hospitalized patients with a clinical diagnosis of lower limb cellulitis was conducted at UKM Medical Centre, January-August 2015. Each patient was compared to two age and gender-matched control patients. All patients were interviewed and examined for risk factors of cellulitis.

    RESULTS: A total of 96 cellulitis patients and 192 controls participated in this study. The cellulitis patients included 61 males and 35 females with a mean age of 62.07±15.43 years. The majority of patients were experiencing their first episode of cellulitis. Multivariate analysis showed a previous history of cellulitis (OR 25.53; 95% CI 4.73-137.79), sole anomalies (OR 16.32; 95% CI 6.65-40.06), ulceration (OR 14.86; 95% CI 1.00-219.39), venous insufficiency (OR 10.46 95% CI 1.98-55.22), interdigital intertrigo (OR 8.86; 95% CI 3.33-23.56), eczema (OR 5.74; 95% CI 0.96.-34.21), and limb edema (OR 3.95; 95% CI 1.82-8.59) were the significant risk factors for lower limb cellulitis.

    CONCLUSION: Previous cellulitis and factors causing skin barrier disruption such as sole anomalies, ulceration, venous insufficiency, eczema, intertrigo, and limb edema were the risk factors for lower limb cellulitis. Physician awareness, early detection, and treatment of these factors at the primary care level may prevent hospital admission and morbidity associated with cellulitis.

    An accurate diagnosis for toxoplasmosis is crucial for pregnant women as this infection may lead to severe sequelae in the fetus. The value of IgG avidity assay as a tool to determine acute and chronic toxoplasmosis during pregnancy was evaluated in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). In this study, 281 serum samples from 281 pregnant women in various trimesters were collected. These samples were assayed using specific anti-Toxoplasma IgM and IgG antibodies, followed by IgG avidity test. The overall seroprevalence of toxoplasmosis in pregnant women was 35.2% (33.5% for anti-Toxoplasma IgG and 1.8% for both anti-Toxoplasma IgG and IgM antibodies). Of 5 (1.8%) serum samples positive for IgM ELISA, 4 had high-avidity antibodies, suggesting past infection and one sample with borderline avidity index. Two samples with low avidity were from IgM negative serum samples. The IgG avidity assay exhibited an excellent specificity of 97.6% and a negative predictive value (NPV) of 95.6%. The study also demonstrated no significant correlation between avidity indexes of the sera with IgG (r=0.12, p=0.24) and IgM (r=-0.00, p=0.98), suggesting the complementary needs of the two tests for a better diagnosis outcome. These findings highlight the usefulness of IgG avidity assay in excluding a recently acquired toxoplasmosis infection in IgM-positive serum sample.
