A 43-year-old man presented with acute extensive anterior ST-segment elevation myocardial infarction. During coronary angiogram, a segment of myocardial bridging was noted in the mid-segment of left anterior descending artery. The association of myocardial bridging and an anterior ST segment elevation is rarely reported in the medical literature. Myocardial bridging is caused by systolic compression of a coronary artery by overlying myocardium tissue. It is a rare coronary artery anomaly, which usually has a benign prognosis despite some case reports of myocardial ischemia leading to myocardial infarction, lethal arrhythmias and sudden cardiac death. We report one such case of myocardial bridging that was complicated with acute extensive anterior myocardial infarction.
Introduction: Dengue is one of the commonest infections in Malaysia and it is a notifi able disease. Even
though the diagnosis of classical dengue fever and dengue haemorrhagic fever can be recognized clinically, the diagnosis remains a challenge in areas where it could not be differentiated with other febrile illnesses. The aim of this study was to focus on the specifi c and consistent morphological features observed in blood fi lms of dengue infection. Materials and Methods: In all 400 cases of dengue infection serologically diagnosed in the Tengku Ampuan Afzan Hospital (HTAA) during May to October 2007, only a total of 27 cases had blood fi lms examined, and thus were included in this study. These blood fi lms were re-examined by two pathologists from HTAA. The full blood count parameters were also retrieved and studied. Results: We consistently found typical reactive lymphocytes [n= 23 (85%)] and thrombocytopenia [n=21, (77.8%)] in the cases. However, leucopenia was present only in 9 cases (33%). Conclusion: The presence of typical reactive lymphocyte is a consistent fi nding in dengue fever and thus could have a signifi cant role in supporting the diagnosis of dengue infection.
Introduction: Each year, more than 20 million people are injured and 1.17 million are killed due to road
traffi c accidents. Developing countries account for over 85% of the deaths, and close to 90% of the disability caused by road traffi c crashes worldwide. The objectives of this study were to determine the knowledge, attitudes and practice and the factors infl uencing university students in Malaysia concerning road traffic accident. Materials and Methods: This study was conducted among the students of Management and Science University, Malaysia. The questionnaire was distributed randomly to the students of the Faculty of Health and Life Sciences. Data was analyzed using SPSS version 13, T-test and ANOVA. Results: The total number of 109 students with the mean age of 20.94±1.89 years participated in this study. Approximately 39 (35.7%) of the participant had been involved in one or more than one road traffi c accident. About 93.6% of them were very strongly/strongly convinced of seat belts importance. Multivariate analysis using the multiple linear regression method showed that age and attitude were signifi cantly associated with the exposure to the accident. Conclusion: The study participants had moderate knowledge about road traffic regulations and most of them mentioned that high speed, drivers’ lack of awareness about traffi c regulation and laws, and drivers’ non-compliance with traffi c rules and regulation were the most important cause of road traffic accidents. Almost all students were very strongly/strongly convinced of seatbelts importance. Age and attitude were signifi cantly associated with the exposure to the accident.
Introduction: Honey has potent bactericidal activity against many pathogenic organisms, including various Gram-negative and Gram-positive bacteria. This study aimed to determine the antimicrobial effect of Malaysian honey against different species of human pathogens using optimized honey broth media. Materials and Methods: The antimicrobial activity of honey against standard strains of Gram-negative and Grampositive bacteria and yeast was tested in vitro by the broth dilution method using 10%-100% w/v concentrations prepared in tryptic soy broth. Results: Streptococcus pyogenes was the most sensitive pathogen, it was completely inhibited by 30% honey broth medium. The most resistant were E. faecalis, S. aureus and MRSA, but they were all completely inhibited by 80% honey broth medium. Conclusion: Honey is shown to possess antimicrobial activity against human Gram-positive and negative medically important bacteria.
Pain is infl uenced by multiple factors including personal experience, psychological, sociocultural and situational factors. Failure to recognise pain will lead to poor patient management and deleterious effect on the patients wellbeing. Assessing pain in paediatric and cognitively compromised patients remains a challenge. Pain assessment in these groups of patients depends on the observers assessment and studies have shown the discrepancy between the observers assessment and patients verbal report. A specifi c and accurate tool is required to assist in the pain assessment. Although there are assessment tools available using behaviour scoring system and physiological indicators, none of the tool demonstrates its superiority than the others. Biochemical indicators such as stress hormones are frequently measured and used in con-junction with verbal reports; however they are non specifi c to pain and are increased in infl ammation, haemodynamic and emotional changes. The association between immunological indicators e.g. IL-1 , IL-6, IL- 8 and clinical pain has been shown, however; the defi nite correlation of the changes in the indicators and the level of pain is still unclear and may require further investigation.
Paragangliomas are uncommon tumors arising from the neuroendocrine elements (chief cells) of the paraganglia and symmetrically distributed along the aorta in close association with the sympathetic chain. Although functional tumors are easier to diagnose due to the clinical fi ndings caused by excess secretion of catecholamines and an elevation of the urinary catecholamine levels, however the diagnosis of nonfunctioning paraganglioma of the retroperitoneum is diffi cult and only few cases have been made before exploratory laparotomy. Although our patient was initially planned and operated by our gynaecological team, the incidental findings had to involve the general surgeons. She is fortunate that the tumour did not show any features of malignancy nor metastasis, however a long time follow up is needed in case of any possible recurrence.
Patient with thyroid mass rarely presents in emergency situation. It is because the nature of the mass is that it usually increases slowly in size. Thus, any surgical intervention can be planned electively. The most common condition that necessitates urgent intervention, is upper airway compromise due to sudden rapid increase in size of the swelling. This can be due to intralesional bleeding or superimposed infection on the enlarged gland. We report a case of urgent completion thyroidectomy performed to a patient with fungating recurrent papillary carcinoma who present with bleeding from the mass externally.
High frequency oscillating ventilation (HFOV) provides a rescue therapy for patients with refractory hypoxaemia in severe acute respiratory distress syndrome (ARDS). HFOV utilizes high mean airway pressures to maintain an open lung and low tidal volumes at a high frequency that allows for adequate ventilation while at the same time preventing alveolar overdistension. This seems to be an ideal lung protective ventilation strategies to prevent ventilator-induced lung injury (VILI)2. We reported a case of severe extrapulmonary ARDS secondary to acute lymphoblastic leukaemia responding to the use of HFOV.
A 29-year-old, smoker, diabetic, hypertensive and hypercholesterolemic man was diagnosed of having severe coronary artery disease with a critical left main stem stenosis. On-pump coronary artery bypass graft surgery (CABG) was performed using conduits from the left internal mammary artery as well as the left radial artery and right saphenous vein which were both harvested endoscopically. He was discharged after a week of uneventful recovery. This case emphasizes on the best possible management of conduits selection, intraoperative myocardial protection and the risk factors modifi cation in achieving a long term graft patency and avoiding premature cardiac related death.
Introduction: Maternal psychological well-being determines early mother-infant relationship and babys health. Paying attention on this aspect is essential particularly in early postpartum period. This study aimed to determine early psychological reactions toward socioeconomic profi les, delivery methods and delivery outcomes among postpartum mothers in Kuala Lumpur Hospital. Materials and Methods: A total of 150 two week-postpartum mothers participated in this cross sectional study and their psychological perspective was measured by using the Depressive, Anxiety and Stress Scale (DASS). Results: 4%, 16% and 4.7% of respondents had significant depressive, anxiety and stress levels respectively. Conclusion: Socioeconomic variables such household income, level of education and presence of medical illness were statistically signifi cant to determine early postpartum psychological reactions but not the modes or outcomes of delivery.

Introduction: The study was done at the aim to assess the functionality and viability of the β cells of the streptozotocin-induced diabetic rats model following repetitive dosage of administration of ethanolic extracts of Andrographis paniculata. Materials and Methods: The diabetic rats were treated with the extracts for fourteen days and at the dose given was 500 mg/kg twice daily. The assessments were made on fasting blood glucose, insulin, and immunohistochemical aspect of β cells before and after treatment. Results: The results showed that there was a signifi cant reduction on fasting blood glucose levels in metformin, 95% and 50% ethanolic plant extracts-treated groups but on insulin level only 95% and 50% ethanolic extracts-treated groups gave a signifi cant reduction(p
Introduction: Diabetes Mellitus (DM) is a chronic metabolite disorder with high potential of multisystemic medical complications especially among poorly controlled patients. This study was conducted at Raja Perempuan Zainab II Hospital, Kota Bharu with objectives to explore the pattern of common diabetic mellitus type 2 complications and to compare between gender and races in relation to other risk factors during their hospitalization. Materials and Methods: This is a retrospective study based on patients’ record involving 215 patients (110 women and 105 men) who were admitted with diabetic complications in medical ward for a period of 6 months (January to June 2006) Results: Out of total 300 identifi ed subjects, 285 case notes were traceable. From 285, 84.6% (241 subjects) were diagnosed as DM type 2. 215 out of 241 subjects (89.2%) had one or more diabetic complications. In general the most common diabetic complication was diabetic nephropathy 34.9% (75 patients). When we compared between genders, diabetic foot ulcers was the most common diabetic complications among males (43.8%) and diabetic nephropathy for females (40.9%). A total of 199 patients (92.6%) had poor blood sugar control during their hospitalization and 103 patients (47.9%) had hypertension. Conclusion: Patients with DM type 2 had a high prevalence of complications. Common diabetic complications among genders were varied. Patients with diabetic complications had high prevalence of risk factors such as poor blood sugar control, concomitant hypertension and smoking habit.
Introduction: This study measured the health-related quality of life (HRQoL) among COPD patients attending outpatient clinic at Institute of Respiratory Medicine, Kuala Lumpur.
Materials and Methods: A cross sectional survey was conducted from November 2008 to January 2009 on 99 COPD patients. Subjects were interviewed through socio-demographic and health characteristics. The HRQoL was measured using the SF-36v2 questionnaires.
Results: Majority of the subjects were above 60 years (64.6%) with mean age of 64.10 ± 11.04 years, male (84.8%), Malays (49.5%), married (74.7%), primary educational level(57.6%), income level below RM1000 (39.4%), ex-smoker (64.6%), moderate COPD (40.4%), 1 to 5 years of illness (62.6%), presence of co-morbidities (65.7%) and satisfied with support from caregiver (48.5%). The total mean score for physical health component summary (PCS) was 41.64 ± 7.99 and mental health component summary (MCS) was 46.53 ± 13.21.
Conclusion: There were significant differences in PCS for different educational level (p<0.05) and socio-economic status (p<0.01). The MCS were signifi cantly different between ethnicity (p<0.05) and level of satisfaction with support from caregiver (p<0.01). This finding provides information that needed focus in
healthcare services.

A preliminary study on the vertical dispersal of Aedes populations in high-rise
apartments was carried out in Presint 9, Putrajaya, Malaysia. Ovitraps were placed indoors
within four blocks of high-rise apartments from the ground floors (0.0 – 3.0 m) until up
to the tenth floors (28.1 – 30.0 m). Aedes aegypti was the dominant species found in the
ovitraps (87.85%), while Aedes albopictus was found in lower numbers. From total number
of larvae collected (650), 40.92% of these larvae were obtained from the fourth block;
Block D. The peak density of Aedes sp. was observed at level 6 (16.1 – 18.0 m), while
Ae. aegypti was found until the tenth floor (28.1 – 30.0 m). In contrast, Ae. albopictus
was found only up to the sixth floor (16.1 – 18.0 m). A poor correlation of the mean
number of Aedes larvae collected with the level of high-rise apartments occupied (N=40;
ρ=-0.349) was also observed which indicated the possibility of lesser Aedes populations
to be found at higher level of high-rise apartments. Therefore, larger scale studies are
strongly recommended to examine the vertical dispersal of Aedes mosquitoes.

Nine species of mosquitoes in eight genera are recorded for the first time in Singapore. An additional two species were overlooked in a 1986 checklist for mosquitoes in Singapore, and one was described after 1986. Location and habitat data are provided for the nine new records. With the inclusion of these new records the number of species reported from Singapore is 137.
Hypopygiopsis violacea, a species of fly of forensic importance, was recovered from a corpse and described for the first time. The morphological structures of the second and third instar larvae of four specimens were examined using light microscope. Observations were focused on three main morphological characters: cephalopharyngeal skeleton, anterior and posterior spiracles. Cephalopharyngeal skeleton of second instar larva is darkly pigmented and without accessory sclerite below the mouth hook. The anterior spiracles of second and third instar larvae have 8-9 papillae each, arranged in a single row. The posterior spiracle of second instar larva has two spiracular slits with no thickening of peritreme. This differentiates it from the third instar, whereby the latter has three slits for each posterior spiracle. Cephalopharyngeal skeleton of third instar larva is heavily pigmented. An accessory sclerite is found below the hook part of third instar larva but is absent in second instar. Peritreme of the posterior spiracle of third instar larva is thick almost complete encircling a button. The intersegmental spines of the cuticular surface are dome-shaped and unicuspid. Third instar larva of this species is large with size approximately 15 mm long. These findings provide important identification features of immature stages of Hy. violacea which could be useful in forensic entomology.
The pupae of Desmometopa sp. (Diptera: Milichiidae) were collected from a human corpse found indoor in active decay stage together with the larvae of Sarcophagidae, Synthesiomyia nudiseta (Wulp), Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart). This research note is the first report of the Desmometopa sp. recovered from a human corpse in Malaysia.
In vitro culture of Toxoplasma gondii can provide tachyzoites which are active, viable and with desirable purity. Thus the aim of this study was to optimize the cell culture method for T. gondii propagation to obtain a consistent source of parasites with maximum yield and viability, but minimum host cell contamination for use in production of excretory-scretory antigen. Tachyzoites with seed counts of 1×106, 1×107 and 1×108 harvested from infected mice were added to VERO cells of different degrees of confluence, namely 50%, 85% and 100%, and examined periodically using an inverted microscope. When the maximum release of the tachyzoites was observed from the host cells, the culture supernatant was removed and the tachyzoites harvested. Using a Neubauer chamber, the percentages of viable tachyzoites and host cell contamination were determined using trypan blue stain. Parameters that gave the best yield and purity of viable tachyzoites were found to be as follows: VERO cells at 85% confluence in DMEM medium and inoculum comprising 1×107 tachyzoites. After about 3 days post infection, the tachyzoites multiplied 78×, with a yield of ~7.8×108 per flask, 99% viability and 3% host cell contamination. This study has successfully optimized the method of propagation of T. gondii tachyzoites in VERO cells which produce parasites with high yield, purity and viability.
The interspecific competition between a new cockroach pest species in Southeast Asia, the Smooth cockroach, Symploce pallens (Stephens) and the ubiquitous German cockroach, Blattella germanica (L.) was studied under different food and water regimes (unlimited food and water [control], limited water, limited food and limited food and water). Both species were found to have equal chances to coexist when both food and water are unlimited, when food is a limiting factor, and when both food and water are limited. However, under shorter evaluation periods (eg. 60 and 120 days), the intrinsic rate of increase (rn) of S. pallens appeared to be significantly lower than that of the B. germanica. This is possibly due to the shorter nymphal development
period and higher fecundity of the latter species when compared to S. pallens. Both the food and
water availability factor showed significant effects on the rn of both species.
Proteins on the surface of Plasmodium falciparum merozoites are good targets for vaccine development against malaria because they are accessible to antibodies in the plasma. The 19kDa C-terminus of merozoite surface protein-1 (MSP-119) has been shown to induce both inhibitory as well as blocking antibodies, the latter blocking the protective effects of the former. Inhibitory antibodies bind to MSP-119 and inhibit merozoite invasion of red blood cells (RBC) but the binding of blocking antibodies can prevent binding of inhibitory antibodies thereby allowing the parasite to invade RBC. We constructed a synthetic version of the MSP-119 of the P. falciparum using mycobacterium codon usage by assembly PCR. The synthetic MSP-119 was mutated at various sites to promote the production of inhibitory but not blocking antibodies as previously reported. The native and mutated MSP-119 were cloned and expressed in Mycobacterium bovis bacille Calmette-Guerin (BCG) and the expressions of the recombinant proteins were detected by specific monoclonal antibodies (mAbs) namely, 12.10 and 1E1 against MSP-119 using Western blotting. The mutated MSP-119 protein reacted with the inhibitory mAb, 12.10, but not the blocking mAb, 1E1, paving the way for the construction of a potential recombinant BCG (rBCG) blood stage vaccine against malaria.
