The aim of the study was to assess the prevalence of Sarcocystis infection in wild and peri-urban rodents in some states in Peninsular Malaysia. The thigh muscle from these rodents were formalin preserved, sectioned and stained with hematoxylin and eosin and examined under light microscopy. Of the 146 muscle tissue examined only 73 were positive for Sarcocystis infection.
Morphological identification showed the presence of some new morphological types to be present. Different species of Sarcocystis were seen in the sections but more extensive studies are needed to identify them to species level.
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.
Background: Problem based learning (PBL) is a student-centered curriculum delivery tool believed to promote active student participation. Though the PBL is student-centered, the facilitator plays an important role in maintaining the integrity of this system by providing balance in group interaction and discussion of learning issues. In International Medical University (IMU) one of the strategies to ensure the quality of the facilitators was the pre and post PBL meetings. This study aimed to gauge its usefulness in ensuring the quality of PBL facilitation.
Method: The questionnaire to study the perceptions of PBL facilitators on the pre and post PBL meetings included close ended questions on pre and post PBL meeting’s attendance and their scored opinion in improving PBL facilitation skills, open ended questions inviting suggestions to improve these meetings and PBL facilitation in IMU as a whole and self-evaluation as an effective PBL facilitator using a six point Likert scale to a list of statements.
Results: 84.2% of facilitators agreed the meetings were beneficial. Self-evaluation of their facilitator effectiveness showed on average ratings of seven out of ten indicating strong confidence in facilitating skills. Suggestions ensuring facilitator quality included content expert briefing in pre PBL meetings and student appraisals of facilitators given weightage in staff appraisal.
Conclusion: Pre and post PBL meetings enhanced facilitator comfort with the triggers, adding to their confidence and provided a venue to obtain feedback on the triggers.
Background: There is a lack of information on the practice of family planning among Muslim women in New York City in the United States of America (USA) [hereinafter known as “Muslim women residing in the United States” (MWRIU)], Tehran in the Islamic Republic of Iran (IRI) and Kuala Lumpur, Malaysia.
The limited figures on this issue are either outdated or mere estimates. The importance of sexual and reproductive health of Muslim women is expected to have massive effects on the social and economic progress of developing countries like the IRI and Malaysia. It is also expected to have imperative impacts on the attempts to empower the MWRIU community and enhance their health status to meet the national standards.
Objective: The study objective is to explore and compare the practice of family planning, namely on contraceptive use and abortion among Muslim women in 3 major cities of different countries.
Methodology: A survey of 379, 377 and 380 respondents from New York City, Tehran and Kuala Lumpur respectively was conducted in 2013 using self-administered questionnaires.
Results: There were significant differences in contraceptive and abortion practices across these countries (P<0.01). While a significant 86.6% of Iranian and 66.2% of the MWRIU used contraception, only 22.9% of the Malaysian women did so. For abortion, 13.6% of the MWRIU and 6.3% of the Malaysian respondents had abortion at least once; while only 22% of Iranians revealed their abortion history, totaling 32.1% of them who had abortion. Financial problems and having an unsupportive husband were among the major factors hindering their practice of healthy family planning.
Conclusion: Educational campaigns should be promoted to increase the awareness on the permissibility of family planning in Islam, as well as on sexual and reproductive rights.
Background: The tissue specimens used for extraction of DNA in this study were from rodents trapped in four states in Peninsular Malaysia, namely Kedah, Kelantan, Selangor and Johor. Methods: Histological sections of these rodent muscle tissues stained with hematoxylin and eos in showed infection with Sarcocystis spp. Based on these results, the current study was carried out to determine the phylogenetic relationship among the identified Sarcocystis spp. in these rodents.The formalin fixed paraffin embedded (FFPE) rodent muscle blocks were subjected to DNA extraction and followed with semi nested PCR targeting 5’ and 3’ regions of 18S rRNA of Sarcocystis spp. Results: Phylogenetic analysis showed two distinct groups of Sarcocystis spp. among the rodents in Peninsular Malaysia. Most of the identified Sarcocystis spp. were genetically closely related to Sarcocystis rodentifelis and Sarcocystis muris and were also observed to be genetically closely related to Sarcocystis sp. ex Columba livia and Sarcocystis sp. cyst type I ex Anser albifrons. Conclusion: Further classification to confirm these Sarcocystis spp. was not possible as only partial sequences of 18S rRNA was available and this was insufficient for
optimal differentiation.
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.
Background: Clinical teaching is an important and
essential teaching tool in the clinical area. Clinical
teaching and learning is essential for the development
and progression of experiential nursing knowledge.
Objectives: This research study aims to identify the
perceptions and evaluations regarding clinical teaching
among Year 2 and Year 3 nursing students, and also to
find out if there are any differences in the perceptions
and evaluations of the nursing students in regards to
clinical teaching.
Methods: The formula for calculating the sample
size was adopted from Morris (2005). The sample size
obtained from the calculation with the confidence
interval of 95%, was 132 participants. The participants
were taken from a universal population of 142 diploma
nursing students: 50 Year 2 nursing students and
92 Year 3 nursing students from the International
Medical College in Selangor. The research instrument
used was the Bedside Teaching Evaluation questionnaire
that was adapted with approval by the writer from
the University of Witwatersrand Department of
Surgery (2008). A pilot study was conducted on 20
participants of Year 1 to Year 3 nursing students from the
Assunta College of Nursing, with a Cronbach’s alpha
reliability index of 0.89.
Results: The data collected were analysed using
descriptive statistics to find out the participant’s
perceptions and evaluations regards clinical teaching;
and also to compare the perceptions and evaluations
between the two groups of nursing students from Years 2
and 3. The study findings showed that 46% (n=142) of
the respondents had a good feedback on all the five (5)
items under the perceptions of clinical teaching whereas
42% (n=142) of the respondents had a moderate view
on all the five (5) items in the perceptions of clinical
teaching sessions. With regards to the evaluation of
clinical teaching sessions, 50% of the respondents had
a moderate feedback on all the three (3) items in this
section.
Conclusion: Most of the participants perceived and evaluated the clinical teaching as an important teachinglearning
strategy in enhancing clinical learning.
Introduction: Perioperative care is nursing care provided
by perioperative nurses to surgical patients during the
perioperative period. Its role is important as patients
especially those who had undergone coronary artery
bypass graft (CABG) surgery encounter high levels of
psychological and physical stress.
Objective: To determine the needs of CABG patients
throughout the perioperative period and how well those
needs were met.
Methods: This is a cross sectional descriptive survey.
A total of 88 patients who had undergone coronary
artery bypass graft were recruited through census
sampling. The instrument which was adapted and used
with permission for this study was “Survey of Patient
Needs and Experiences during the Perioperative Period’
questionnaire (Davis et al., 2014).
Results: The patients perceived the perioperative
needs in the post-anaesthesia care unit area to be the
most important (M = 2.89, SD = 0.06). Perioperative
needs which were rated the highest for each of the
four time periods were “Having information about the
surgical procedure itself”, “Having your family member
or significant other with you in the pre-surgical area
complications”, “Being treated with respect and with
dignity by hospital personnel” and “Having your family
member or significant other visit you in the recovery
room”. Overall, patients perceived their needs during
perioperative period to be partly met (M = 2.73, SD =
0.07) with post-anaesthesia care unit area being rated
the highest (M = 2.81, SD = 0.06).
Conclusion: The results of this study highlighted the
perceived needs of patients undergoing coronary artery
bypass graft surgery throughout their perioperative
period. In order to improve the quality of perioperative
care for patients, nurses need to take into consideration
the important needs identified by the patients and
address the items which were not meeting the needs of
the patients.
Introduction: The prevalence of cataract surgeries
ranges from 7 to 12 million cases in 2000, 20 million
in 2010 and an estimation of 32 million cataract
surgeries annually by the year 2020 worldwide (WHO,
2015). Traditionally, the healthcare providers were
only able to give health education before the patient
is discharged from the healthcare setting while followup
can only be done when the patient comes for their
follow-up. But most of the patients will remain confused
or had forgotten about the post-operative care even
after receiving a comprehensive discharge preparation.
However, with the advancement of technologies in
this modern era, nurse-led telephone follow-up can be
considered as a tool to assist healthcare providers in the
follow-up care in Malaysia. On the same note, a private
eye specialist organisation with centres throughout
Malaysia, had taken the initiative to provide telephone
follow-up service for their patients with three main
objectives namely, to provide pre- and post-education
on cataract surgery, to detect early post cataract surgery
complications as well as to minimise anxiety among
their patients. However, till date no patient feedback
regarding the service was conducted.
Objective: The research objective for this study was to
determine patient’s level of satisfaction with the nurseled
telephone follow-up after cataract surgery at a private
eye specialist centre in Penang.
Method: A cross sectional quantitative descriptive study
design was used to study ninety post cataract patients in
a private hospital, Penang through universal sampling
method. A validated self-developed questionnaire based
on the three main objectives of the telephone follow-up
service was used for this study.
Results: Overall, the level of patient’s satisfaction with
nurse-led telephone follow-up after cataract surgery at
a private eye specialist centre in Penang was high (49.9
±4.85) especially for the health education provided
(4.18 ±0.21) followed by the effort to detect early
complications (4.16 ±0.12) and to minimise patients’
anxiety level (4.16 ±0.12).
Surgeries are seen as stressors that trigger preoperative anxiety. Preparing the patients for surgery through preoperative teaching becomes crucial to allay anxiety level. In a cross sectional descriptive study conducted on eighty patients (age: 18–65 yr) who had undergone open abdominal surgery, 78.8% (n=63) stated that they experienced anxiety prior to surgery. Among these anxious respondents, 47.5% (n=38) experienced high state anxiety. Three of the top information that patients perceived as important to allay anxiety towards major surgery were: details of surgery, details of nursing care to surgery and information on anaesthesia. Nurses working in the surgical wards need to proactively address patients’ psychological concerns towards surgery and provide preoperative information based on patients’ needs to allay anxiety.
Developing and adult worms of the human lymphatic filarial parasites (Wuchereria bancrofti,
Brugia malayi, and Brugia timori) are located mainly in the lymphatic system and occasionally in aberrant sites like subcutaneous and conjunctival cysts. Lymphatic
pathology ranging from dilatation of lymphatic channels and lymphangiectasia are detected on ultrasonography in apparently healthy, amicrofilaraemic, but filarial antigen positive individuals in endemic areas. Microfilariae are distributed in various organs and may be associated with immune mediated pathology at these sites; tropical pulmonary eosinophilia is characterized by intense immune mediated destruction of microfilariae in the lung parenchyma. In the spleen and other sites, nodular granulomatous lesions can occur where microfilariae are trapped and destroyed. The finding of Wolbachia endosymbionts in all stages of lymphatic filarial parasites has provided new insight on the adverse reactions
associated with anti-filarial chemotherapy. Inflammatory molecules mainly lipopolysaccharide (LPS)-like molecules released from endosymbionts on death of the
parasites are largely responsible for the adverse reactions encountered during anti-filarial chemotherapy. Prenatal tolerance or sensitization to parasite derived molecules can immune-modulate and contribute to both pathology and susceptibility/resistance to infection. Pathological responses thus depend not only on exposure to filarial antigens/infection, but also on host-parasiteendosymbiont factors and to intervention with antifilarial treatment. Treatment induced or host mediated death of parasites are associated with various grades of inflammatory response, in which eosinophils and LPS from endosymbionts play prominent roles, leading to death of the parasite, granulomatous formation, organization and fibrosis. The non-human primate (Presbytis spp.) model of
Brugia malayi developed for the tertiary screening of anti-filarial compounds has provided unique opportunities for the longitudinal study of the pathology associated with lymphatic filariasis. The pathology in this non-human primate model closely follows that seen in
human lymphatic filarial infections and correlates with clinical evidence of lymphatic pathology as detected with ultrasonography. These studies also show that successful treatment as detected by loss of motility and calcification of worms on ultrasonography is associated with reversal of early dilatations of lymphatic channels.
Background: Continuing professional development (CPD) is a primary strategy for nurses to keep abreast with the rapid changes in the health care practices of current times. Evidence has shown that nurses lack the initiative to take up the additional CPD offered by their organisation and have to be persuaded to do so once they have achieved the minimum 25 points of CPD mandated by Malaysia Professional Regulatory Board of Nursing (MNB).
Objective: To determine the extent to which nurses from a private hospital in Melaka will participate in CPD and the challenges affecting them from participating in CPD
upon achieving the mandatory CPD points specified by MNB.
Methods: This is a cross-sectional descriptive survey. A sample of 188 registered nurses (RNs) from a private hospital in Melaka was recruited via purposive sampling technique to complete a self-reporting questionnaire. The instrument which was adapted and used with permission was pilot-tested for reliability and validated by content experts to ensure its suitability for this local study.
Results: The survey showed that 82.4% of the registered nurses (RNs) had attained additional CPD points apart from the minimum 25 CPD points stipulated by MNB. The findings on RNs reading journals or engaged in distance learning programmes were not encouraging as the percentages were only 31.4% and the latter, 9%. In-service talks, grand round discussions and online sources of continual nursing education that do not require the RNs to be away from their work duties were the most frequent type of CPD activities participated by the RNs as compared to conferences, workshops, distance learning programmes or post basic courses. The top 3 challenges that affect RNs’ participation in CPD were time constraint (90.4%), work commitments (85.6%) and difficulty in getting nominated (53.7%) to attend the CPD activities of their choice.
Conclusions: The results of this study highlighted the respondents’ views to the management on the importance to align the approach of sponsoring CPD courses according to the nurses’ needs in order to meet their context of practice. The management also ought to take into consideration the identified challenges encountered by the nurses to participate in CPD upon achieving their mandatory CPD points specified by MNB.
Papillary thyroid microcarcinoma is not uncommon
and constitutes almost one third of all differentiated
thyroid carcinomas. It is generally regarded as low risk
and usually an incidental finding from histopathology
examination. Some areas of management of this entity
remains uncertain and requires a multidisciplinary
approach. We present a patient who initially came to
us with symptoms of hyperthyroidism, later underwent
thyroidectomy for a suspicious lesion but was found to
have micropapillary thyroid carcinoma in another part
of her thyroid gland.
Nebulization with B-agonist and administration of systemic corticosteroids are standard treatments for severe asthma exacerbations, but corticosteroids take several hours to become effective. IV magnesium sulphate (MgSO4) acts faster and has both antiinflammatory and bronchodilating properties. It appears to have played a pivotal role in the successful management of a child with severe asthma exacerbation and atelectasis unresponsive to conventional therapy. A literature review reveals that the results of IV MgSO4 are much greater in children than in adults, and can avoid the need to hospitalize 25% of children presenting with severe asthma. Magnesium sulphate appears safe to use.
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.
The International Medical University (IMU) has encouraged and facilitated research activities since 2001. Research activities by undergraduates, postgraduates, and faculty members have increased substantially since then. The governance aspects of research activities are closely monitored by the Institutional Review Board which is the IMU-Joint Committee on Research and Ethics. (Copied from article)
Introduction: Undergraduate medical education should be broad-based, holistic, integrated and should promote a framework for the development of higher order cognitive skills like communication, professionalism and teamwork to prepare the student for a life-long challenging medical career. Recent calls for a competency-based medical education require, in addition, competency in clinical and procedural skills prior to graduation. This study investigates how often opportunities exist for medical students to perform four common ward procedures prior to graduation.
Method: A prospective cross-sectional study to assess the opportunities a medical student have in performing four common ward procedures, comprising intravenous cannulation, nasogastric tube insertion, urinary catheterisation and chest tube insertion, in a State General hospital in Malaysia was done.
Results: A medical student has sufficient opportunity to perform only intravenous cannulation prior to graduation. He has a remote chance to insert a urinary catheter and is unlikely to have the opportunity to insert a nasogastric tube or insert a chest tube prior to graduation.
Conclusion: Although competency in clinical skills and procedural skills prior to graduation are desirable, this is increasingly difficult to achieve due to shortage of clinical material, teachers to supervise, the large numbers of medical students and house officers, the short time spent on the main disciplines and the failure of many universities to invest heavily in skills laboratories staffed by full time clinicians. The calls to introduce competency-based medical education in undergraduate medical education, particularly in procedural competence, should take into account the challenges in delivery and the realities in the hospitals today. This is necessary to avoid demoralising students who are unable to achieve their quota of procedures through no fault of theirs.

This paper reviews available reports on the omega-6 (linoleic acid, LA) and omega-3 fatty acid
[alpha-linolenic acid (ALA) + eicosapentaenoic acid (EPA) + docosahexaenoic acid) intakes amongst Malaysians against Malaysian Recommended Nutrient Intakes (RNI), focussing particularly on pregnant and lactating women because of the availability of data for these latter vulnerable groups. Overall, the omega-6 and omega-3 fatty acid nutrition amongst Malaysians are poor and far from desirable. The nutritional situation regarding these long-chain polyunsaturated fatty acids
(LCPUFA) amongst Malaysian pregnant and lactating women is alarming and warrants urgent attention in nutrition promotion activities/counselling. Daily consumption of LA by these women and other Malaysians studied ranged from 3.69 - 5.61 % kcal with 38-60% of individuals not meeting their RNIs. Daily intakes of omega-3 fatty acids faired worse, averaging 0.21- 0.33 % kcal with as high as 92% of subjects in one study not meeting their RNIs. The omega-6 to omega-3 fatty acid
ratios obtained in the studies reviewed are about 20:1, which is way above the World Health Organisationrecommended ratio of 5-10:1. Dietary sources of these omega- fatty acids in the subjects studied are chicken, fish and milk. Since local foods are not particularly rich in LCPUFA such as EPA and DHA, the options to improve EPA/DHA nutrition amongst Malaysians are
the greater consumption of omega-3 enriched foods and in the case of pregnant and lactating women, LCPUFA supplementation may warrant serious consideration.
Keriorrhoea is the involuntarily passing of orange oil per rectum. One of us (PMB) had the misfortune to experience this symptom, together with considerable gastrointestinal disturbances for a prolonged period of time after consumption of a deep sea fish, orange roughy, which is rich in liquid wax esters (LWEs). This paper presents a summary of available evidence concerned with the physiology and pathology of ingestion of LWEs, which can enter the human diet in substantial amounts from consumption of several species of deep-sea fish. LWEs are poorly digested and absorbed by the human body. They generally cause keriorrhoea when ingested deliberately or accidentally. Jojoba oil, which is a plant LWE, together with certain nutritional products (e.g. olestra) and medical (e.g. Orlistat) which are not LWEs may mimic the effects of LWEs, and cause similar gastrointestinal disturbances. This paper discusses the potential effects of LWEs as components of gastrointestinal micelles, and predicts that the orange oil which is leaked from a bout of keriorrhoea may contain considerable volumes of triacylglycerols (TAGs).
We report a case of occult primary spontaneous
pneumothorax in a 30 years-old woman. She
developed symptoms and signs that were suggestive of
pneumothorax. However, chest radiograph failed to
reveal pneumothorax. Therefore, we proceeded with
computed tomography (CT) thorax which revealed
significantly moderate right pneumothorax. The
diagnostic approach and the management of this case
are discussed.
