    Background: The World Health Organization recommends the practice of exclusive breastfeeding of infants for the first 6 months after birth. The objective of present study was to estimate the prevalence and the factors influencing exclusive breastfeeding. The perceptions of mothers about breastfeeding in an urban slum area of Western India were also enquired.
    Methods: This cross sectional study was conducted over six months amongst 200 mothers of children in the age group of 6 – 12 months attending the growth and development clinic in one of the urban health centres. Data was collected using a pre-tested, structured questionnaire on breastfeeding practices. Factors related to exclusive breastfeeding were analysed using bivariate and multivariate analysis.
    Results: Prevalence of exclusive breastfeeding reported by the participants was 61.5%. Having a male child, maternal age < 30 years, level of education of mother parity, receiving infant feeding advice, initiation of breastfeeding within one hour of birth and administration of colostrum to the baby were associated with exclusive breastfeeding (p

    Background: Circumcision though not mentioned in the Quran is believed to be a compulsory practice among the Muslims. In Malaysia, although there are several methods of circumcision available and traditional circumcision is still popular.
    Methods: A cross-sectional survey was carried out in a small fishing village of Kedah to study the methods of circumcision available to the villagers. This was followed with an in-depth interview conducted with ‘Tok Mudim’, a practitioner of traditional method of circumcision.
    Results: Forty three of the eligible 71 subjects participated in the study giving the response rate as 60.5%. The most common age for circumcision was 9 years old. Despite private clinics being the most common place of circumcisions, there was an increasing number of boys going to the ‘Tok Mudim’ for circumcision. A Mass Circumcision Ceremony is traditionally practiced. The ‘Tok Mudim’ described the procedure in detail and was of the opinion that the reason traditional method is still popular was because of the fear of injections and impotency among the parents. Most common complication faced by the ‘Tok Mudim’ was bleeding and infection.
    Discussion and Conclusion: Till the community shifts entirely to using modern medicine, there is a need to integrate traditional practitioners into the system. Training the ‘Tok Mudim’ to use modern instruments and aseptic techniques should be considered.

    Pharmacogenomics (or pharmacogenetics), the study of the effects of genetic differences on a person’s response to drugs, can help in optimizing drug efficacy and minimizing adverse drug reactions. Interperson difference in drug metabolism is one of the important consequences of such genetic variation. This variation is determined in part by mutations in cytochrome P450 enzymes (CYPs). IMU is part of a major collaborative research project in the area of phamacogenetics and drug metabolism. Working together with USM and UiTM, our group has, since 2000, generated useful population database on genetic polymorphism of various CYP isoforms. We have successfully genotyped three major ethnic groups, Malay, Indian and Chinese for their allelic frequency of important isoforms. These include CYP2D6, CYP2C9, CYP2C8 and CYP2A6. Data generated so far collectively have contributed to our effort in mapping and constructing genomic database for Malaysian population.
    Since early 2002, our research has been focusing on developing in vitro methods in studying the functional consequences of genetic polymorphism of CYP enzymes. Using site-directed mutagenesis, CYP mutants, carrying nucleotide changes as reported in known alleles in human populations, were generated and expressed in E. coli system, and the expressed recombinant proteins were characterized using enzyme assays to determine the functional consequences of mutations. We have established a series of HPLC (high performance liquid chromatography)-based and fluorescence-based assays to investigate CYP activities. Assays that have been developed include tolbutamide methylhydroxylase, paclitaxel 6α-hydroxylase, dextromethorphan O-demethylation, testosterone 6β-hydroxylation and coumarin 7-hydroxylase assays. These assays serve as activity markers allowing comparison of catalytic activities of mutant proteins generated. Another focus of our work is to use the developed assays as a screening tool to investigate drug-herb interactions. This was achieved by co-incubation of herbal extracts and active constituents with the probe substrates in the assays followed by characterization of the kinetic behaviors of the enzymes involved using various pharmacokinetic parameters such as Km, Vmax, IC50 and Ki. This work is currently carried out with collaboration from the Institute for Medical Research (IMR) and is supported by MOSTI’s eScienceFund under RM9. It is envisaged that this screening work will give us insights on the potential of the commonly used herbs to cause pharmacokinetic interactions with other drug substrates, and allow us to elucidate the mechanisms involved in the interactions.

    Malaysia has good environmental laws to protect the outdoor environment and public health. However there are no laws governing indoor air quality (IAQ) and the knowledge among the public about its importance is also lacking. Environmental professionals think it is not a priority and this influences the policy decisions in the country. Therefore there is a need to create awareness by way of research, education and other promotional activities. What is much needed at this time is the establishment of standards for the conduct of risk assessment studies. To establish standards we need reliable data which can be used to develop appropriate guidelines for the purpose of mitigation and adaptation programmes. IAQ can have significant influence on health resulting in drop in productivity and economy of a country. It has been estimated that in the US, building related illnesses (BRI) symptoms have a relationship with decrease (3 to 5%) in work performance in an affected population resulting in an annual loss of US$60 billion in revenue. However, based on efficient management programmes they have also projected that the potential annual savings can be in the region of US$10 to 30 billion. This establishes that fact that good management programmes based on efficient guidelines is of economic value to a country and wellbeing of the population. The IMU has embarked on a research programme to collect the much-needed data for the framing of a good IAQ guideline for Malaysia.

    Introduction: Pneumonia is the most common diagnosis made in hospitalised children. The Malaysian Clinical Practice Guidelines on pneumonia and respiratory tract infections provides a comprehensive guidance in the local context. We evaluated the documented assessment and management of children diagnosed with pneumonia admitted to the children’s ward, Hospital Batu Pahat against this guideline.
    Methods: We performed a retrospective analysis of hospital case notes for children admitted from January to May 2004.
    Results: Ninety six case notes were analysed. Most patients (84%) had at least four positive clinical features leading to the diagnosis of pneumonia. 92% met the guideline criteria for admission. Sp02 was performed for 58% on admission, and 58% with reading below 95% received supplemental oxygen. Throughout hospital stay, each patient had an average of four investigations (range: 1 – 12). Among 23 patients who had further investigations, justifications were only recorded in seven patients (30.4%), and changes in management resulted in 23%. The most common antibiotic prescribed was intravenous Penicillin (97 %). In 17 patients who met the guideline classification for severe pneumonia, none received the recommended antibiotic combination. The median time to fever resolution was 22 hours (range 2 – 268), and median hospital stay was 3 days (range 1 – 12).
    Conclusions: Although the quality of clinical assessment and antibiotic choices were acceptable, there was a failure to critically evaluate patients according to disease severity and initiate corresponding investigations and managements. Future efforts need to be directed at promoting further guideline adherence and the exercise of critical judgment in patient evaluation.

    The incidence of tuberculosis (TB) is currently increasing. HIV induced immuno-suppression modifies the clinical presentation of TB. Our aim is to determine the differences in clinical presentation of HIV-TB co-infection based on their CD4 counts. This retrospective study looked at cases of adult active TB and HIV-1 co-infection treated in Penang Hospital from January 2004 to December 2005. Of the 820 patients treated for active TB, HIV-1 seropositivity rate was 12.6% (103 patients). Majority of HIV-1 co-infected patients presented with prolonged insidious and non-specific symptoms like weight loss, fever and night sweats. The clinical presentation of TB depended on the stage of HIV-1 infection and associated degree of immunodeficiency. Compared to the less immuno-compromised HIV-1 and TB co-infected population (CD4 > 200/mm3 ), patients with CD4 counts ≤ 200 are more likely to have atypical chest radiographs (P = 0.009). During active TB, the Mantoux test was positive in 12 (14.5%) HIV-1 infected patients with a CD4 counts ≤ 200/mm3 and in 16 (80%) of those with CD4 counts > 200/mm3 (P = 0.0001). In our series, the AFB smear / AFB culture and type of TB did not show obvious correlation with CD4 counts. Therefore to diagnose TB in severely immuno-compromised HIV patients, we need to have a high index of suspicion.

    Background: Positron Emission Tomography and Computed Tomography (PET-CT) imaging is shown to influence a decision change in managing non-small cell lung carcinoma (NSCLC). The introduction of such a facility in Malaysia is relatively recent, and its impact from its utility is currently being assessed.
    Aim: In a tertiary referral centre possessing the only PET-CT facility in northern Peninsular Malaysia, we evaluated the potential roles of PET-CT in referred patients with non-small cell lung carcinoma.
    Methodology: Sixty eligible adult cases with NSCLC, between September 2005 and December 2007, were retrospectively reviewed. Relevant data was collected using standard questionnaire for indications, staging of disease, and outcomes in terms of recurrence and response to prescribed cancer-specific therapy.
    Results: The indications for PET-CT were: staging of a newly diagnosed non-small cell lung carcinoma (25.0%); post-operative restaging (21.7%); exclusion of recurrence or metastasis (18.3%); establishing diagnosis of carcinoma (13.3%); assessment of response to treatment (11.7%), and for surveillance (10.0%). The use of PET-CT was shown to induce a change in the staging, compared with non-PET conventional means in 69.2% of patients with newly diagnosed lung carcinoma (upstaged in 55.5%; downstaged in 44.5%) and in 65.0% of patients who underwent cancer-specific treatments (upstaged in 38.5%; downstaged in 61.5%). PET-CT detected recurrence in 62.5% who underwent the imaging to exclude a recurrence or metastasis.
    Conclusion: PET-CT has affected the staging of a large proportion of our local Malaysian patients. Like elsewhere, the availability of such a facility is likely to have important influence in overall management of NSCLC in Malaysia.

    Introduction: Task-based learning (TBL) has been accepted as an effective tool in teaching and learning activities in most medical schools. Many studies have looked at competencies and learning outcomes essential for undergraduates. Among the essential competencies are interpersonal skills and the ability to engage in a group discussion which this study has focused on. The evidence supporting higher interpersonal skills is however limited because many relevant competencies are hard to measure and require long observational periods.
    Objective: To determine students’ self-perceived value of TBL in enhancing their interpersonal skills during the clinical phase.
    Material and Methods: All students’ (semesters 6-10) in the clinical school of International Medical University (IMU) were invited to participate in this cross-sectional study done in December 2007 utilising a self-administered questionnaire with a 5-point Likert scale. It assessed the students’ perception on TBL sessions conducted during their clinical attachments in the various disciplines. Mean-scores, standard deviations, and confidence interval were used.
    Results: Response rate was 62%. The results indicated that students were favorable in their opinion on TBL as a suitable forum for active communication and participation in group discussion. The results also show that both male and female students’ have similar perception. As for the comparison according to semesters, this showed that students’ maturity does not influence their perception as well.
    Conclusion: In conclusion, the study has shown positive students’ perception on the effect of TBL on acquired skills such as interpersonal communication. Our findings are consistent with many earlier studies which show students’ perception of the method of learning as important factor in the enhancement of their interpersonal skills which is fundamental to clinical practice. Further research is necessary; long-term and larger scale observational studies would undoubtedly be optimal to minimise response bias.

    Abstract: Ampicillin-sulbactam combination is the most frequently prescribed antibiotic in diabetic foot ulcers. We conducted a retrospective study to evaluate the antibiotic sensitivity of bacteria isolated to this antibiotic. In 33 patients with diabetic foot ulcer (September 2008-March 2009), 67% were culture positive in which Citrobacter spp accounted for 36% of these isolates. The rest isolated included Pseudomonas aeruginosa (22%), Proteus spp (18%), Acinetobacter spp (9%), Klebsiella pneumoniae (5%), Escherichia coli (5%) and Staphylococcus aureus (5%). These isolates were more likely to be ampicillin-resistant (n=18) than were ampicillin-sensitive isolates (n=4). Ampicillin resistance has raised our concern about current practice of prescribing ampicillin/ sulbactam as monotherapy for majority of our patients with such ulcers.

    In the last decade or so, Medical education all over the world has been inundated with innovations in education, which include innovations in curricular design, delivery as well as assessments. There is a need to reflect on the effectives of these innovations
    on the learner. Hence the theme chosen for the 2009 International Medical Education Conference (IMEC 2009) was “Reflections on Innovations”. The Organising Committee felt that it was timely for medical educators everywhere to reflect and evaluate the effect of the many innovations adopted by their schools. (Copied from article)

    Gestational breast cancer (GBC) or pregnancy-associated breast cancer was defined as breast cancer diagnosed during pregnancy and within 1 year of delivery. Breast cancer is the second commonest cancer after cervical seen in pregnancy and lactation. Nevertheless, the incidence is low and accounts for approximately 1 in 3000 of pregnancies. A delay in diagnosis is common and 70% to 89% of patients with operable primary lesions already have positive axillary lymph nodes. Breast cancer identified during pregnancy can be extremely distressing for the mother despite it has similar course of disease and prognosis seen in non-pregnant women of the same age and stage of disease. Diagnostic and treatment options should be carefully decided to prevent further harm to the mother or any potential risk to the developing fetus.

    Pneumonia continues to a disease of potentially high morbidity and mortality, sparing no children or healthy adults. Over the years, clinical practice guidelines and institution-initiated management protocols have been introduced with the intention of improving outcomes by ensuring appropriate assessment and management of pneumonia. Correct assessment of pneumonia type and severity will lead to appropriate course of action. This is especially true when deciding whether the patient can be treated at home and the type of empiric antibiotic(s) that should be prescribed. The latter has a strong evidence-base when examined in the light of clinical practice guidelines. Non-guideline adherent empiric antibiotic regimes used in hospitalized community acquired pneumonia (CAP) are adversely associated with time to clinical stability, time to switch therapy, length of hospital stay, hospital survival and hospital re-admission rates. Our own local study on hospitalized patients with Klebsiella pneumoniae pneumonia, a highranking community-acquired organism in Malaysia, also testified to the association of adverse hospital outcomes with inappropriate choice of empiric antibiotic(s).

    Item analysis is the process of collecting, summarizing and using information from students’ responses to assess the quality of test items. Difficulty index (P) and Discrimination index (D) are two parameters which help evaluate the standard of MCQ questions used in an examination, with abnormal values indicating poor quality. In this study, 120 test items of 12 Type A MCQ tests of Foundation 1 multi-disciplinary summative assessment from M2 / 2003 to M2 / 2006 cohorts of International Medical University were selected and their P-scores in percent and D-scores were estimated using Microsoft Office Excel. The relationship between the item difficulty index and discrimination index for each test item was determined by Pearson correlation analysis using SPSS 11.5. Mean difficulty index scores of the individual summative tests were in the range of 64% to 89%. One-third of total test items crossed the difficulty index of 80% indicating that those items were easy for the students. Sixty seven percent of the test items showed acceptable (> 0.2) discrimination index. Forty five out of 120 test items showed excellent discrimination index. Discrimination index correlated poorly with difficulty index (r = -0.325). In conclusion, a consistent level of test difficulty and discrimination indices was maintained from 2003 to 2006 in all the twelve summative type A MCQ tests.

    IMU is one of 17 institutions of higher learning conducting the Bachelor of Pharmacy course
    in Malaysia. The White paper on pharmacy student professionalism by the Task Force of the American Pharmaceutical Association Academy of Students of Pharmacy together with the American Association of Colleges of Pharmacy Council of Deans mentioned10 essential traits of a professional, recommending their early development. Since the beginning of theIMU Bachelor of Pharmacy (BPharm) (Hons) course in July 2004 on Registration Day, IMU has adopted the concept of developing professionalism in the pharmacy student from the very first day of university, by having the White Coat Ceremony where the entire class takes the Pledge of Professionalism (adapted from the Task Force) against the “Code of Conduct for Pharmacists and Bodies Corporate” by the Pharmacy Board of Malaysia in the presence of the Senior Director of the Pharmaceutical Services Division of the Ministry of
    Health, Malaysia and the President of the Malaysian Pharmaceutical Society (MPS). Throughout their 4 years in IMU, the pharmacy students are exposed to various aspects of professionalism in different subjects in their curriculum. On 23rd April 2012, when the fifth cohort of BPharm students received their final examination results, “Pharmacy Professional Day” was launched. The graduating students took the Oath of a Pharmacist (adapted from the American Association of Colleges of Pharmacy’s Oath with slight amendment). Talks by alumni and speakers from MPS aimed to facilitate the transition of the new graduate to working life as a pharmacist.

    There has been a significant decline in maternal mortality from 540 per 100,000 live births
    in I957 to 28 per 100,000 in 2010. This decline is due to several factors. Firstly the introduction of the rural health infrastructure which is mainly constructing health centres and midwife clinics for the rural population. This provided the accessibility and availability of primary health care and specially, antenatal care for the women. This also helped to increase the antenatal coverage for the women to 98% in 2010 and it increased the average number of antenatal visits per women from6 in 1980 to 12 visits in 2010 for pregnant women. Along with the introduction of health centres, another main feature was the introduction of specific programmes to address the needs of the women and children. In the 1950s the introduction of Maternal and Child Health (MCH) programme was an important
    step. Later in the late 1970s there was the introduction of the High Risk Approach in MCH care and Safe Motherhood in the 1980s. In 1990, an important step was the introduction of the Confidential Enquiry into Maternal Deaths (CEMD). Another significant factor in the reduction is the identification of high risk mothers and this is being done by the introduction of the colour coding system in the health centres. Other factors include the increase in the number of safe deliveries by skilled personnel and the reduction in the number of deliveries by the Traditional Birth Attendants (TBAs). The reduction in fertility rate from 6.3 in 1960 to 3.3 in 2010 has been another important factor. To achieve the 2015 Millennium Development Goals (MDG) to further reduce maternal deaths by 50%, more needs to be done especially to identify maternal deaths that are missed by omission or misclassification and also to capture the late maternal deaths.

    It is estimated that more than 1.1 billion adults and 115 million children worldwide are overweight. In Malaysia, the second and third National Health and Morbidity Surveys in 1996 and 2006 respectively reported a three-fold increase in obesity prevalence among adults, surging from 4.4% to 14% over the 10-year period. Evidence of rising childhood obesity has also emerged. The aim of this article is to gather evidence from food availability data for an insight into population shifts in dietary patterns that may help explain the rising obesity in this country. The nutrition transition was delineated in conjunction with the epidemiologic transition in order to explain the convergence of dietary practices, and the high prevalence of obesity and diet-related non-communicable diseases worldwide. The Food Balance Sheets for Malaysia from 1967 to 2007 were used to provide estimates and trends for the availability of foods and calories. Evidence is generated that indicate at least two major upward shifts in the dietary patterns in Malaysia in the past 4 decades.
    These shifts have led to the rising availability of calories from animal products, and from sugar and sweeteners. These major dietary shifts, together with increased sedentariness, constitute core public health challenges faced in addressing the country’s obesity and noncommunicable diseases (NCD) conundrum.
