BACKGROUND: to determine the usefulness of Doppler ultrasound measurement of resistive index (RI) in differentiating obstructive from non-obstructive hydronephrosis in children.
METHODS: From August 2011 to November 2012, renal Doppler assessments of the intra-renal renal arteries were performed on 16 children (19 kidneys) with congenital hydronephrosis. the independent t-test was used to assess for significant difference in RI values between those with obstructive hydronephrosis (6 kidneys) and those with non-obstructive hydronephrosis (13 kidneys) as determined by dynamic renal scintigraphy. the assessor was blinded to the clinical findings and scintigraphy results.
RESULTS: RI was significantly different between obstructive and non-obstructive hydronephrosis. Obstructive hydronephrosis returned higher RI values, with mean RI of 0.78. Mean RI in non-obstructive hydronephrosis was 0.70, and the difference was significant (p <0.05). the sensitivity and specificity of Doppler ultrasound were 100% and 53% respectively.
CONCLUSION: Doppler ultrasound measurement of resistive index is useful in differentiating obstructive from nonobstructive hydronephrosis and provides an alternative non-ionizing investigation.

BACKGROUND: The determination of smoking prevalence and its associated factors among the elderly could provide evidence-based findings to guide the planning and implementation of policy in order to will help in reducing the morbidity and mortality of smoking-related diseases, thus increase their quality of life. This paper describes the rate of smoking and identifies the factor(s) associated with smoking among the elderly in Malaysia.
METHODS: A representative sample of 2674 respondents was obtained via a two-stage sampling method in proportion to population size. Face-to-face interviews were conducted using a set of standardized validated questionnaire. Data was weighted by taking into consideration the complex sampling design and non-response rate prior to data analysis. Univariable and multivariable logistic regression were used to determine the factor/s associated with smoking.
RESULTS: The prevalence of non-smokers, ex-smokers and current smokers among Malaysians aged 60 years and above were 36.3 % (95 % CI = 32.7-39.8), 24.4 % (95 % CI = 21.2-27.5) and 11.9 % (95 % CI = 9.5-14.3), respectively. Current smokers were significantly more prevalent in men (28.1 %) than in women (2.9 %), but the prevalence declined with advancing age, higher educational attainment, and among respondents with known diabetes, hypertension and hypercholesterolemia. Multivariable analysis revealed that males (aOR, 18.6, 95 % CI 10.9-31.9) and other Bumiputras (aOR 2.58, 95 % CI 1.29-5.15) were more likely to smoke. in addition, elderly with lower educational attainment (aOR, 1.70, 95 % CI 1.24-7.41) and those without/unknown hypertension also reported higher likelihood to be current smokers (aOR 1.98, 95 % CI 1.35-2.83). However, there were no significant associations between respondents with no/unknown diabetes or hypercholesterolemia with smoking.
CONCLUSIONS: In short, smoking is common among elderly men in Malaysia. Therefore, intervention programs should integrate the present findings to reduce the smoking rate and increase the smoking cessation rate among the elderly in Malaysia and subsequently to reduce the burden of smoking-related disease.

INTRODUCTION: Effective communication in a clinical environment plays a vital role in patient assessment and treatment. The aim of this study was to understand the experiences of Malaysian medical students concerning communication barriers during clinical practice. The goal was to provide answers for three important research questions, i.e., 1) Are communication barriers an impediment to Malaysian students during clinical teaching? 2) What is the nature of the language barriers that the students encounter? and 3) What are the best ways of reducing these barriers during clinical teaching?
METHODS: The qualitative method was used to conduct the research, and open-ended questionnaires were used to collect the data. The study was conducted on 95 fourth-, fifth-, and sixth-year students, 80% of whom completed the study.
RESULTS: Medical students from Malaysia who have limited knowledge of the Arabic language experience some difficulties in communicating with staff members, patients, and nurses during their clinical practices.
CONCLUSION: Successful orientation of students to the language used in the clinical environment will help the students overcome the communication barriers they encounter during their clinical practices.

Cross-sectional view echocardiography is an efficient non-invasive diagnostic tool for characterizing Myocardial Infarction (MI) and stages of expansion leading to heart failure. An automated computer-aided technique of cross-sectional echocardiography feature assessment can aid clinicians in early and more reliable detection of MI patients before subsequent catastrophic post-MI medical conditions. Therefore, this paper proposes a novel Myocardial Infarction Index (MII) to discriminate infarcted and normal myocardium using features extracted from apical cross-sectional views of echocardiograms. The cross-sectional view of normal and MI echocardiography images are represented as textons using Maximum Responses (MR8) filter banks. Fractal Dimension (FD), Higher-Order Statistics (HOS), Hu's moments, Gabor Transform features, Fuzzy Entropy (FEnt), Energy, Local binary Pattern (LBP), Renyi's Entropy (REnt), Shannon's Entropy (ShEnt), and Kapur's Entropy (KEnt) features are extracted from textons. These features are ranked using t-test and fuzzy Max-Relevancy and Min-Redundancy (mRMR) ranking methods. Then, combinations of highly ranked features are used in the formulation and development of an integrated MII. This calculated novel MII is used to accurately and quickly detect infarcted myocardium by using one numerical value. Also, the highly ranked features are subjected to classification using different classifiers for the characterization of normal and MI LV ultrasound images using a minimum number of features. Our current technique is able to characterize MI with an average accuracy of 94.37%, sensitivity of 91.25% and specificity of 97.50% with 8 apical four chambers view features extracted from only single frame per patient making this a more reliable and accurate classification.
BACKGROUND: Respiratory diseases represent a significant impact on health care. A cross-sectional, multicountry (India, Korea, Malaysia, Singapore, Taiwan, and Thailand) observational study was conducted to investigate the proportion of adult patients who received care for a primary diagnosis of asthma, allergic rhinitis (AR), chronic obstructive pulmonary disease (COPD), or rhinosinusitis.
OBJECTIVE: To determine the proportion of patients who received care for asthma, AR, COPD, and rhinosinusitis, and the frequency and main symptoms reported.
METHODS: Patients ages ≥18 years, who presented to a physician with symptoms that met the diagnostic criteria for a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Patients and physicians completed a survey that contained questions related to demographics and respiratory symptoms.
RESULTS: A total of 13,902 patients with a respiratory disorder were screened, of whom 7030 were eligible and 5250 enrolled. The highest percentage of patients who received care had a primary diagnosis of AR (14.0% [95% confidence interval {CI}, 13.4-14.6%]), followed by asthma (13.5% [95% CI, 12.9-14.1%]), rhinosinusitis (5.4% [95% CI, 4.6-5.3%]), and COPD (4.9% [95% CI, 5.0-5.7%]). Patients with a primary diagnosis of COPD (73%), followed by asthma (61%), rhinosinusitis (59%), and AR (47%) most frequently reported cough as a symptom. Cough was the main reason for seeking medical care among patients with a primary diagnosis of COPD (43%), asthma (33%), rhinosinusitis (13%), and AR (11%).
CONCLUSION: Asthma, AR, COPD, and rhinosinusitis represent a significant proportion of respiratory disorders in patients who presented to health care professionals in the Asia-Pacific region, many with concomitant disease. Cough was a prominent symptom and the major reason for patients with respiratory diseases to seek medical care.

BACKGROUND: Undergraduate medical students have been the most distressed group among the student population. Depression and anxiety have been found to be more prevalent in this group of students compared to others.
OBJECTIVE: This study was conducted to determine the prevalence and predictors of suicidality among undergraduate medical students in a public university.
METHODS: This was an analytical cross-sectional study, conducted in a public university in Selangor, Malaysia. Data were collected using self-administered questionnaires from January to February 2013, and analysed using the Statistical Package for Social Sciences Software (version 21).
RESULTS: Out of 625 undergraduate medical students, 537 (85.9%) participated in the study. The prevalence of the suicidality among undergraduate medical students was 7.0%. The significant predictors of suicidality based on multiple logistic regression were the respondent's lifetime suicide attempts (Adjusted Odds Ratio, AOR 10.4, 95% CI 2.7 to 40.9); depression (AOR 5.9, 95% CI 1.5 to 23.0); breaking off a steady love relationship (AOR 5.4, 95% CI 1.3 to 22.4); hopelessness (AOR 4.9, 95% CI 1.1 to 21.6); and something valued being lost or stolen (AOR 4.4, 95% CI 1.2 to 15.9).
CONCLUSION: These findings indicate that mental health care services should be strengthened at university level. The results show a need for an intervention programme to reduce suicidality among the undergraduate medical students.
INTRODUCTION: The lack of evidence that proves the benefit of traditional and complementary medicines (T & CM) in treating chronic medical conditions does not deter its usage among patients worldwide. Prevalence of usage among post-stroke patients in Malaysia especially is unknown. This study aims to determine the prevalence, practice and perception of T & CM use among stroke survivors attending an outpatient rehabilitation program in a teaching hospital.
METHODS: A cross-sectional study was conducted among 104 post stroke patients attending an outpatient rehabilitation program. A structured self-administered questionnaire was used to collect data on sociodemographic and clinical profile of patients, as well as types of therapy used and perception on T & CM usage. Descriptive analysis was done, and bivariate analysis was used to determine associations between categorical data.
RESULTS: Mean age of patients was 62 years (SD 12.2), 54% were Chinese and 75% of the patients had ischaemic stroke. Mean age of T & CM users was younger compared to non- T & CM users (61 years vs. 66 years, p=0.04). Two-thirds (66%) of patients admitted to concurrent T & CM usage while attending conventional post stroke rehabilitation. Acupuncture (40.4%), massage (40.4%) and traditional Chinese medicine (11.5%) were the most common T & CM used. Positive perception was recorded in terms of ability of T & CM usage to relieve post stroke symptoms (68%), and it was safe to use because it was made from 'natural sources'. Negative perception recorded: T & CM caused significant adverse effects (57.6%) and was not safe to be used in combination with other conventional medicines (62.5%).
CONCLUSIONS: Concurrent T & CM usage among post-stroke patients attending structured outpatient rehabilitation program is widely practised especially acupuncture, massage and traditional Chinese medicines. Overall the perception towards its use is favourable.

BACKGROUND: Good coronary care begins from the patient's home, including early transportation. As such, it is recommended that the patients activate ambulances, rather than to use their own transportations to reach the hospitals. It is not known whether Malaysian patients prefer to use private transportations or ambulances when they develop chest pain.
OBJECTIVES: This study is conducted to explore the question of the choice of transportation modes among patients with acute coronary syndrome and the reasons behind their choices.
METHODS: This is a structured interview survey on patients diagnosed with acute coronary syndrome (ACS) in emergency department of Hospital Universiti Sains Malaysia from April 2012 to September 2012.
RESULTS: Out of the 110 patients surveyed, 105 (95.5%) patients chose to use own transportation when they developed symptoms suggestive of ACS. Only 3 patients (2.7%) came to the emergency department within 1 hour of onset, and all these 3 patients chose to use ambulances as their modes of transportation. None of the patients who chose own transportation came within the first hour of symptoms onset. This is shown to be statistically significant (p<0.001). The level of education as well as past history of ischemic heart disease did not significantly influence the patients' choice of transportation.
CONCLUSION: The admonishment by various international resuscitation councils that patients with chest pain should be transported via ambulances may not be as straightforward as it seems. Numerous local and regional socio-cultural and logistic factors may need to be addressed.
Perception of healthcare providers who worked with family medicine specialists (FMSs) could translate into the effectiveness of primary healthcare delivery in daily practices. This study examined perceptions of public healthcare providers/professionals (PHCPs) on FMSs at public health clinics throughout Malaysia. This was a cross-sectional study in 2012-2013 using postal method targeting PHCPs from three categories of health facilities, namely health clinics, health offices and hospitals. A structured questionnaire was developed to assess PHCP's perception of FMS's clinical competency, safety practice, ethical and professional values, and research involvement. It consists of 37 items with Likert scale of strongly disagree (a score of 1) to strongly agree (a score of 5). Interaction and independent effect of the independent variables were tested and adjusted means score were reported. The participants' response rate was 58.0% (780/1345) with almost equal proportion from each of the three public healthcare facilities. There were more positive perceptions than negative among the PHCPs. FMSs were perceived to provide effective and safe treatment to their patients equally disregards of patient's social background. However, there were some concerns of FMSs not doing home visits, not seeing walk-in patients, had long appointment time, not active in scientific research, writing and publication. There were significant differences in perception based on a respondent's health care facility (p
Early child multilingual acquisition is under-explored. Using a cross-sectional study approach, the present research investigates the rate of multilingual phonological acquisition of English-Mandarin-Malay by 64 ethnic Chinese children aged 2;06-4;05 in Malaysia--a multiracial-multilingual country of Asia. The aims of the study are to provide clinical norms for speech development in the multilingual children and to compare multilingual acquisition with monolingual and bilingual acquisition. An innovative multilingual phonological test which adopts well-defined scoring criteria drawing upon local accents of English, Mandarin and Malay is proposed and described in this article. This procedure has been neglected in the few existing Chinese bilingual phonological acquisition studies resulting in peculiar findings. The multilingual children show comparable phonological acquisition milestones to that of monolingual and bilingual peers acquiring the same languages. The implications of the present results are discussed. The present findings contribute to the development of models and theories of child multilingual acquisition.
INTRODUCTION: Aimed at providing integrated multi-level crisis intervention to women experiencing violence such as rape, One Stop Crisis Centre (OSCC) in Malaysia is often located in the emergency department. Hence, it is imperative that emergency department healthcare providers possess adequate knowledge and acceptable attitudes and practices to ensure the smooth running of an efficient OSCC work process.
METHOD: To study the knowledge, attitude and practice of rape management in OSCC among four groups of healthcare providers in the emergency department [i.e., the emergency medicine doctors (EDs), the staff nurses (SNs), the medical assistants (MAs) and the hospital attendants (HAs)], a selfadministered questionnaire in the form of Likert scale was conducted from January to October 2013. Correct or favourable responses were scored appropriately.
RESULTS: Out of the 159 participants invited, 110 responded (69.2% response rate). As all data sets in the Knowledge, Attitude and Practice sections are non-parametric, Kruskal- Wallis test was performed. Homogeneity of variance was verified using non-parametric Levene test. In all three sections, there are statistically significant differences in scores obtained among the four groups of healthcare providers with H(3) = 16.0, p<0.001 for Knowledge, H(3) = 27.1, p<0.001 for Attitude and H(3) = 15.8, p<0.001 for Practice sections. Generally, the SNs obtained the highest mean rank score in the knowledge and practice sections but the EDs obtained the highest mean rank score in the attitude section. Some of the responses implied that our healthcare providers have the victim-blaming tendency that can negatively impact the victims.
CONCLUSION: Healthcare providers must not only have adequate knowledge but also the non-judgemental attitude towards victims in OSCC.
OBJECTIVE: To identify the stress-prevalence and coping-strategies among University Kebangsaan Malaysia (UKM) medical students.
METHODS: This was an observational study conducted among 234 UKM first and third year medical students. Standardized questionnaire on stress and coping strategies was used. Stress data was related to subjective experiences on some positive and negative adjectives such as tense, relaxed etc. Positive adjectives were measured by sign "++" and "+" scoring "1" while stress-negative adjectives were measured by sign "?" and "-" scoring "0". Forty-eight coping items under task, emotion and avoidance strategies were measured using 5-point Likert-scale.
RESULTS: Overall stress-prevalence was 49%. Female and Malay respondents were more stressed. Significant differences of stress-level was observed between Malays and non Malays in first year (p=0.04) and in third year (p=0.01). Most common strategies used to cope stress was task-oriented while emotion oriented was least.
CONCLUSION: Stress-prevalence and stress-level in UKM medical students was high. Most of the respondents coped stress using task-oriented strategies. Stressor and its effective management must be ensured. Educational institutions should act as a creative designer of learning environment to get relieve from educational stressor.

A survey of specialisation choices was conducted for two batches of medical officers applying to the local medical schools for specialisation in Malaysia. A total of 359 doctors responded, giving a response rate of 71%, with 169 male (44.4%) and 187 female (55.6%) respondents. Surgery ranked highest among the male doctors followed by orthopaedic surgery and internal medicine. Family medicine ranked highest among female doctors followed by public health and anaesthesiology. Among the other specialties, the male doctors preferred otorhinolaryngology while female doctors preferred Pathology. Both male and female doctors chose to be a clinical consultant in a general hospital as the first choice. They prefer to work in or near their hometowns.
A cross sectional study was carried out in Negeri Sembilan to identify factors associated with job satisfaction of doctors serving in Ministry of Health and their intentions to resign. All Ministry of Health doctors currently working in Negeri Sembilan were included in the study and data collection was done via a self-administered postal questionnaire. The response rate was 69.4%. Out of those who responded, only 31.3% had global job satisfaction, with the majority dissatisfied. Intention to resign was high among 32.7% of the respondents. Factors found to be significantly associated with job satisfaction were age, job designation, income, duration of service and intention to resign. Intention to resign was found to be significantly associated with ethnicity and income. From logistic regression, predictors of job satisfaction identified were age, place of first graduation, and satisfaction with status and autonomy, satisfaction with career development, satisfaction with workload and satisfaction with transfers. Predictors of intention to resign were race, income and global job satisfaction.
Blood pressure examination was done manually in 1756 healthy school children aged 6-12 years. Korotkoff 1 represented the systolic blood pressure (SBP) and Korotkoff 5 was taken as the diastolic blood pressure (DBP). Blood pressure percentile charts were then drawn up based on age group and sex regardless of ethnicity. There was a significant correlation between both SBP and DBP to increasing height, weight and body mass index.
OBJECTIVE: To compare parenting stress among Malaysian mothers of children with mental retardation and a control group, and to determine factors associated with stress.
METHODOLOGY: Seventy-five mothers of children with mental retardation aged 4-12 years and 75 controls (those without disabilities who attended the walk-in paediatric clinic) participated in the Parenting Stress Index (PSI). Intelligence quotient (IQ) and Child Behaviour Checklist (CBCL) scores, together with sociodemographic data, were entered into a multiple stepwise regression analysis, using the PSI as the criterion.
RESULTS: Mothers of children with mental retardation scored significantly higher than control subjects in both the child-related domain (difference between means 26.1, 95% confidence interval 19.6-32.5) and parent-related domain (difference between means 15.0, 95% confidence interval 7.9-22.1) of the PSI. The total child behaviour scores from the CBCL (P < 0.01), IQ scores (P < 0.01) and sibship size (P < 0.01) were associated with child-related domain scores. For the parent-related domain, CBCL (P < 0.01) and IQ scores (P = 0.01) remained important factors but Chinese ethnicity (P < 0.01) and maternal unemployment (P < 0.01) were also significant predictors of stress.
CONCLUSION: A large proportion of mothers of children with mental retardation experienced substantial parenting stress, especially Chinese and unemployed mothers, and this warrants appropriate intervention.

Food expenses accounted for 66% 54% of the total income in the two plantations. The nutritional value of foods purchased and consumed and the adequacy of nutrient intakes in two plantations was studied. The diets were found to be inadequate in calories, protein, calcium, iron and riboflavin. Carbohydrates provided the bulk of the calories. The significance of the findings are discussed.
Serum human prolactin (hPRL) levels in Malay women during pregnancy, intrapartum and immediately postpartum have been invest£gated by means of a double-antibody radioimmunoassay technique. There was a progressioe rise of serum prolactin concentration from 31.9 ± 10.4 ng/ml in the first trimester to 242.0 ± 24.6 ng/ml at 36 weeks pregnancy unth. the mean values during the second and third trimester of 118.9 ± 12.7 ng/ml and 214.7 ± 10.3 ng/ml respectively. During intrapartum the concentration of hPRL was 191.9 ± 26.9 ng/ml and ithat of immediately postpartum was 178.3 ± 14.5 ng/ml. Suckling of the breast within 6 hours postpartum has resulted in a minor elevation of prolactin level, and this could have been due to the greater basal prolactin level, and/or the ineffectiveness of suckling as a potent stimulus during this period.
