    A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling.

    An audit of Diabetes Control and Management-Diabetes Registry Malaysia (ADCM-DRM) was started to monitor the provision of diabetes care in the country. A total of 20,646 patients were registered in the registry until 31st December 2008. This report set out to determine the Type 2 diabetes controls and treatment profiles of these cohorts of patients. This was a registry-based observational study conducted from May to December, 2008. An online standard case record form was available for site data providers to register their diabetic patients aged 18 years old and above annually. Demographic data, diabetes duration, treatment modalities, as well as various risk factors and diabetes complications were reported. Data were analyzed using Data Analysis and Statistical Software (Stata) version 9. A total of 81 centres, 6 of which were hospitals, participated in this registry until 31st December 2008, contributing a total of 20646 patients. A majority of them (99.2%) had Type 2 diabetes mellitus. The mean HbA1c was 8.0% (SD 2.10), with 30.1% and 17.9% of the patients who attained HbA1c < 7% and HbA1c < 6.5%, respectively. Metformin was prescribed more than sulfonylurea while only 11% had insulin. A review of the diabetic care policy and strategies in the primary health care clinics is needed to implement a more effective treatment of diabetes in this country.

    Haematuria is a common presentation of bladder cancer and requires a full urologic evaluation. This study aimed to develop a scoring system capable of stratifying patients with haematuria into high or low risk groups for having bladder cancer to help clinicians decide which patients need more urgent assessment. This cross- sectional study included all adult patients referred for haematuria and subsequently undergoing full urological evaluation in the years 2001 to 2011. Risk factors with strong association with bladder cancer in the study population were used to design the scoring system. Accuracy was determined by the area under the receiver operating characteristic (ROC) curve. A total of 325 patients with haematuria were included, out of which 70 (21.5%) were diagnosed to have bladder cancer. Significant risk factors associated with bladder cancer were male gender, a history of cigarette smoking and the presence of gross haematuria. A scoring system using 4 clinical parameters as variables was created. The scores ranged between 6 to 14, and a score of 10 and above indicated high risk for having bladder cancer. It was found to have good accuracy with an area under the ROC curve of 80.4%, while the sensitivity and specificity were 90.0% and 55.7%, respectively. The scoring system designed in this study has the potential to help clinicians stratify patients who present with haematuria into high or low risk for having bladder cancer. This will enable high-risk patients to undergo urologic assessment earlier.

    PURPOSE: The internal drainage provided by a ureteral stent helps with the relief and prevention of ureteral obstruction. By definition, correct stent placement is one with a complete loop in both the renal pelvis and bladder. This prevents stent migration proximally or distally despite urinary flow, patient movement, and ureteral peristalsis.

    METHODS: We performed a comparative prospective cross-sectional study assessing the impact of intravesical stent position on the quality of life in 46 patients with a ureteral stent. This is done using the Ureteral Stent Symptom Questionnaire (USSQ).

    RESULTS: 52.5% of patients had an ipsilateral positioned intravesical stent, while the remaining had their stent positioned contralaterally. Intravesical stent position significantly influenced the quality of life. The USSQ score was worse for the contralateral group. Subscore analysis found that urinary symptoms and body pain index contribute significantly to the morbidity. Majority of patients in the ipsilateral group reported no discomfort as compared to the contralateral group.

    CONCLUSIONS: To the best of our knowledge, this is the first study assessing the impact of intravesical stent position on the quality of life in the Asian population. Intravesical stent position has a significant influence on patient's morbidity and quality of life in particular towards their urinary irritative symptoms and body pain. It is imperative to ensure correct distal placement of ureteric stent that does not cross the midline to the contralateral site. We believe that the USSQ should be used in daily clinical practice in assessing the symptoms related to indwelling ureteric stents.

    BACKGROUND: Turner Syndrome (TS) is a rare sex chromosome abnormality occurring in 1 in 2500 female live births. To date, there is limited data on TS patients in Malaysia. This study aimed to investigate the quality of life (QoL) and body image disturbances among adult population with TS in comparison to age-matched controls in a tertiary hospital in Kuala Lumpur: Hospital Chancellor Tuanku Mukhriz, Universiti Kebangsaan Malaysia (HCTM, UKM).

    METHODS: This was a cross-sectional study carried out in HCTM, UKM, Kuala Lumpur. TS participants who attended clinic in HCTM, UKM and controls who were hospital staff members were recruited via purposive sampling. TS participants' sociodemographic and clinical profiles were retrieved from medical records. Two validated, translated questionnaires; World Health Organization Quality of Life (WHOQOL-BREF) questionnaire and Body Image Disturbances Questionnaires (BIDQ) were completed by participants.

    RESULTS: A total of 34 TS patients were approached and 24 (70.5%) of them participated in this study. Their median (IQR) age was 24.0 (7.0) years and their responses were compared to 60 age-matched healthy females as controls [median age (IQR) = 24.0 (8.0) years]. The most common medical problem in TS participants was premature ovarian insufficiency (n = 23; 95.8%). There were no significant differences between TS and control groups' median scores (overall QOL; 4.00 vs. 4.00, general health; 3.50 vs. 4.00, physical health; 14.86 vs. 15.43, psychological health; 14.67 vs. 14.00 and environment; 15.00 vs. 15.50) of the different WHOQOL-BREF domains. However, TS participants were found to score 13.33 against 16.00, lower than the control group (p

    This study aimed to examine the effect of health consciousness, knowledge about healthy food, attitudes toward healthy food, subjective norms, and perceived behavioural control on the intention to consume healthy food, which subsequently affects the consumption of healthy food among Malaysian young adults. The current study also examined the moderating effect of perceived barriers on the association between intention to consume healthy food and the consumption of healthy food. This study adopted a cross-sectional design and collected quantitative data from 1651 Malaysian young adults (between the age of 18 and 40 years) by sharing a Google form link through social media. The findings reveal that health consciousness, knowledge about healthy food, attitude toward healthy food, subjective norms, and perceived behavioural control had a significant positive effect on the intention to consume healthy food. Findings also show that the intention to consume healthy food has a significant positive effect on the consumption of healthy food among Malaysian young adults. Furthermore, the findings reveal the positive and significant mediating effect of the intention to consume healthy food and the significant moderating effect of perceived barriers on the association between the intention to consume healthy food and the consumption of healthy food. The multi-group analysis revealed that the effect of perceived barriers on the consumption of healthy food and the moderating effect of perceived barriers were significantly higher among urban respondents. Health and agriculture policymakers should focus on the attributes of healthy eating practices and their health benefits to promote the mass adoption of healthy food among Malaysian young adults.

    Social media has changed the marketing phenomenon, as firms use social media to inform, impress, and retain the existing consumers. Social media marketing empowers business firms to generate perceived brand equity activities and build the notion among consumers to continue using the firms' products and services. The current exploratory study aimed to examine the effects of social media marketing activities on brand equity (brand awareness and brand image) and repurchase intention of high-tech products among Chinese consumers. The study used a cross-sectional design, and the final analysis was performed on 477 valid responses that were collected through an online survey. Partial least squares structural equation modelling (PLS-SEM) and artificial neural network (ANN) analysis were performed. The obtained results revealed positive and significant effects of trendiness, interaction, and word of mouth on brand awareness. Customisation, trendiness, interaction, and word of mouth were found to positively affect brand image. Brand awareness and brand image were found to affect repurchase intention. The results of multilayer ANN analysis suggested trendiness as the most notable factor in developing brand awareness and brand image. Brand awareness was found to be an influential factor that nurtures repurchase intention. The study's results confirmed the relevance of social media marketing activities in predicting brand equity and brand loyalty by repurchase intention. Marketing professionals need to concentrate on entertainment and customisation aspects of social media marketing that can help to achieve brand awareness and image. The limitations of study and future research opportunities are presented at the end of this article.

    Early identification and rapid treatment of red tag patients may decrease morbidity and mortality. We examined the clinical characteristics, etiologies and one week mortality rate of red tag (life threatening and potentially life threatening illness) patients at the Hospital Universiti Sains Malaysai (HUSM). A cross-sectional study was conducted at the Emergency Department of the HUSM from 1 August 2006 to 31 January 2007; 440 eligible patients were analyzed. The group had a mean age of 47.2 +/- 22 years, with 67.3% of the patients being male. Twenty-three percent were trauma cases with motor vehicle accident being the major mechanism of injury. Fifty-four percent of the cases had cardiac related illnesses. The mean duration of stay in the Emergency Department (ED) was 3.9 +/- 1.5 hours. The survival rate at one week was 76.6%. The non-trauma group comprised 74.0% of death cases. Acute coronary syndrome and road traffic accidents comprised 22.0% of total death cases at one week. Red tag patients constitute a large proportion of ED cases and may remain in the ED for significant periods of time.

    This study aimed to determine the prevalence of anxiety and burnout, and the coping mechanisms among clinical year undergraduate medical students in Universiti Kebangsaan Malaysia (UKM) during the coronavirus disease 2019 (COVID-19) pandemic. In total, 378 clinical year undergraduate medical students in UKM participated in this cross-sectional study from May to July 2021. A self-administered questionnaire consisting of questions on the participant's sociodemographic data and items from the DASS-21, CBI, and Brief-COPE was distributed. Chi-square and Spearman's correlation tests were used to calculate the correlation coefficient between both anxiety and burnout, and coping mechanisms. The prevalence of anxiety and burnout were 44.2% and 22.2%, respectively. There was a significant difference in the percentage of students with extremely severe anxiety in the presence and absence of burnout, 23.8% vs. 4.8% (p < 0.001). Among the three coping mechanisms, avoidant coping had a significant positive moderate correlation with both the presence of anxiety (r = 0.3966, p < 0.001) and the presence of burnout (r = 0.341, p < 0.001). Meanwhile, coping that was neither approach nor avoidant had a positive weak correlation with the presence of burnout (r = 0.176, p = 0.001). The prevalence of anxiety and burnout was concerning. Increased anxiety and burnout among students may negatively impact aspects of their personal, professional, and academic lives. Early recognition and preventive measures should be emphasised to prevent negative ramifications.

    The aim of the study was to determine coping strategies among breast cancer patients with depression and anxiety during chemotherapy. Methods: Breast cancer patients with confirmed diagnosis who were undergoing out-patient chemotherapy at the Oncology Unit, University Malaya Medical Centre were invited to participate in the study. They were assessed on their socio demographic profiles and clinical history. The Hospital Anxiety Depression Scale (HADS) was used by patients to report anxiety and depression. The Brief COPE Scale was used to assess coping strategies among the patients. Results: One hundred and forty one patients with mean age of fifty years participated in the study. Prevalence for depression was 19.1% and prevalence for anxiety was 24.1%. Patients who were having anxiety symptoms scored significantly higher on denial, behavioural disengagement and venting as their coping strategies compared to patients who were not anxious. Patients with depressive symptoms scored significantly higher in behavioural disengagement and self-blame as their coping strategies compared to those who were not depressed. Conclusion: Breast cancer patients undergoing chemotherapy experienced high level of depressive and anxiety symptoms. However different coping strategies were adopted to cope with their illness, chemotherapy treatment, practical and family problems, emotional and physical symptoms.

    Objectives: To study relationship of depressive symptoms to hypertension. Methods: A cross sectional study was carried out on respondents from Kampung Awal. Hypertension was defined as self-reported or by measurement using a mercury sphymomanometer and depressive symptoms were evaluated by CES-D scale. Results: A total 103 respondents were studied. The male:female ratio was 1:1.5 with mean age of 41.8 years. Majority had formal education up to secondary school. 45% were government servant and over 95% subjects had income of RM1000 or less per each family member per month. 21.4% (n=22) self-reported to have hypertension and 7.8%(n=91) met the criteria for incident hypertension. 7.8% met the criteria for both. Mean score based on CES-D was 13.08. 32.0% subjects had depression. 54 subjects reported never experienced any strain for past 6 months and 24 reported to have 2 or more .61 subjects were overweight with mean value of BMI=26.19 kg/m2. Self-reported hypertension and incident hypertension were strongly associated with age but only selfreported hypertension was strongly associated with overweight. However, there was no significant association between hypertension with chronic strains and depressive symptoms. Conclusions: Depressive symptomatology was not associated with hypertension in this survey. Women had a significant risk in having depressive symptoms. Age =45 years & overweight were significant risks for hypertension. A prospective study will be more useful in the future to find out the association between depression and hypertension.

    Introduction: There is increasing awareness of the contribution of perceived social support (PSS) to emotional and physical well-being. Numerous scales measuring PSS have been developed, including the widely used Multidimensional Scale of Perceived Social Support (MSPSS). The psychometric properties of the MSPSS have been demonstrated in diverse samples, however mostly are conducted in English. Malay is the official languange in Malaysia, and this study was conducted to provide evidence of the validity and reliability of a Malay version MSPSS (MSPSS-M) suited for our population.
    Methods: This is a cross sectional study. The socio-demographic and clinical information of the selected patients from psychiatric outpatient clinic over a 3-month period, were obtained via pre-designed questionnaire, interviews and medical records. Assessment of psychiatric symptoms and social support were measured by various instruments including the Brief Psychiatric Rating Scale (BPRS-E), Depressive, Anxiety and Stress Scale (DASS) and MSPSS-M.
    Results: Data were reported for 228 psychiatric outpatients with the mean age of 40.3 years old. The 3-factor structure of the MSPSS-M (significant others, family, and friends) fitted the data well. The MSPSS-M showed good internal consistency (Cronbach α of 0.89) and validity. The scores of the total subscales for MSPSS-M were negatively correlated with the depression subscale in DASS (P < 0.05). BPRS was negatively correlated with significant others (P < 0.01) compared to the other two subscales in MSPSS-M.
    Conclusions: The Malay version MSPSS (MSPSS-M) is a psychometrically valid instrument with high internal consistency, which is useful in assessing perceived social support in Malaysian population.

    Objective: This systematic review is aimed to quantitatively summarise the
    prevalence of sexual dysfunction among non-SSRI second generation
    antidepressants namely agomelatine, bupropion, duloxetine, venlafaxine, and
    mirtazapine.

    Methods: Relevant studies published from inception till
    December 2012 were identified by searching PubMed, OVID and Embase.
    We included all literatures encompassing randomized controlled, cohort,
    case-controlled and cross-sectional studies, which contained quantitative data
    for prevalence on all aspects of sexual dysfunction in depressive patients who
    were older than 18 years of age. Heterogeneity, publication bias and odds
    ratio were assessed thoroughly.

    Results: In the non-SSRI second generation
    antidepressant group which consisted of 17,316 subjects, various studies
    showed the range of sexual dysfunction prevalence between 0% and 67%.
    Sexual dysfunction in patients who took non-SSRI second generation
    antidepressants constituted a meta-analytical pooled prevalence of 15%, and
    36% in those who took SSRIs. The combined relative risk of sexual
    dysfunction in the non-SSRI second generation antidepressant group when
    compared with SSRI was 0.57.

    Conclusions: The pooled prevalence of sexual
    dysfunction in non-SSRI second generation antidepressant is lower than in
    SSRI antidepressants.

    Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was 70.1± 14.7 and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.

    There is a lack of studies looking into religiosity and religious coping in cancer patient. In this cross-sectional study, we examined the religiosity using Duke University Religion Index, religious coping using Brief Religious Coping Scale, anxiety and depression based on Hospital Anxiety and Depression Scale among 200 cancer patients. The association between religiosity and religious coping with anxiety and depression was studied. The findings showed that subjects with anxiety or depression used more negative religious coping and had lower non-organization religiosity. Hence, measurements in reducing negative religious coping and encouraging religious activities could help to reduce psychological distress in cancer patients.
