    Dental students need to be equipped with skills, knowledge and positive attitudes while providing dental care to the elderly. Reports from Ministry of Health alaysia indicatedthat the prevalence of dental caries and periodontal disease was high among older people in the country. The aim of this study was to assess the knowledge and perception of final year dental students towards the elderly in relation to training of geriatric dentistry in Universiti Kebangsaan Malaysia edical Centre (UKMMC). All the final year dental students were required to complete a questionnaire that comprised of 3 sections: 1) Palmore’s Facts on Aging Quiz II, 2) Oral health and social concerns of patients, and 3) Perception towards the teaching of geriatric dentistry. A total of 83 students participated in the study. Twenty-four per cent (n=20) scored more than 70% to questions on knowledge about older people and 73% (n=61) scored between 50 -700%. The students had ranked physical disability, transportation problems andcomplex and overlapping priorities as reasons for elderly not keeping to their appointments. Majority of the students reported that lack of educational resourcematerials and very minimum clinical sites experience were the main barriers facedduring the course. In conclusion, majority of the students had moderate to goodknowledge about older people and were able to recognize issues of social oncerns that can influence their oral health. In general, there were not many changes in the perceived competencies of managing older patients following the geriatric module.

    This was a retrospective study of operative records between 2000 – 2007 from two ear, nose and throat (ENT) referral centers in Malaysia to review demographic patterns, clinical presentations and management of retropharyngeal abscess (RPA). Our case series comprised of eight patients with five females and three males with a median age at presentation of 47 years. Comorbid factor in this series was diabetes mellitus, with four patients  having diabetes. There were three cases of fish bone ingestion. The commonest presentation was dysphagia or odynophagia. None of them had fever. All patients were treated with broad spectrum intravenous antibiotics (IV) and drainage was performed for the abscess. Four patients underwent transoral drainage with three having the cervical approach and one having spontaneous ruptureAll patients recovered well from the infection and only one patient passed away due to septicaemia.  In conclusion, patients with retropharyngeal abscess may present with vague symptoms of sore throat, odynophagia without fever due to partial antibiotics treatment. A correct diagnosis should be made so that adequate treatment can be given to prevent mortality.

    Patients are increasingly dissatisfied with the “waiting time” and “duration of consultation” at outpatient clinics. A cross sectional study was carried out to measure waiting time and duration of consultation and to examine patients’ level of satisfaction towards waiting time and duration of consultation at the Orthopedic Clinic, Universiti Kebangsaan Malaysia Medical Centre (UKMMC). This study also examined patient’s satisfaction towards the overall clinic services. Data was collected using a self-administered questionnaire. A total of 81 patients participated in this study with a response rate of 100 percent. Findings indicated a significant difference in the mean between expected waiting time level II (from  the time the patient is given the calling number till the time patient is called into the doctor’s room) and the actual waiting time level II experienced. A significant difference in the mean between the expected duration of consultation and the actual duration of consultation experienced was also noted. However, no significant difference was found between the mean of expected waiting time level I (the time patient register at the counter till the patient is given the calling number) and the  actual waiting time (p>0.05).  Overall, patient satisfaction towards waiting time was low (29.6%) and duration of consultation was of moderate level (41.9%). The overall satisfaction towards the clinic services were of average level (56.8%). Findings also indicated that patient satisfaction was not influenced by socio-demographic factors of respondents such as age, ethnic, education level, occupation and income level. Important findings from this study may help staff managing the clinic in addressing patients’ complaint on waiting time and improve patients’ satisfaction on the overall services of the Orthopedic clinic in UKMMC.

    Post operative pain is an expected adverse outcome following surgery and it often delays mobilization and overall recovery. Acute post operative pain is subjective and cannot be measured directly. The objective of this study was to determine nurses’ knowledge and attitude towards post operative pain management. A cross sectional study was conducted in surgical wards and the Intensive Care Unit of Universiti Kebangsaan Malaysia Medical Centre from February to April 2008. A 28 item questionnaire which comprised of two domains: knowledge and attitude towards post operative pain management was used. Eighty four respondents successfully responded to the study. Twenty respondents (25%) possessed high level, 58 respondents (69%) possessed moderate level and 5 respondents (6%) had low knowledge level of post operative pain management. Positive attitude towards post operative pain management was reported by 66 respondents (78.5%). There was a significant relationship between nurses’ academic qualifications and attitude towards post operative pain management (χ² =29.96, p

    Gamma-tocotrienol (GTT) has been shown to exhibit significant antitumor activity in a variety of tumor cells. Previous findings have demonstrated that GTT had antiprolifera-tive effects on a liver cancer cell line (HepG2) with an IC50  value of 170μM. In this study, two dimensional gel electrophoresis (2DE) was used to determine changes in protein expression in HepG2 cell line following treatment with GTT. The ultimate aim is to identify the possible molecular mechanisms involved in GTT antitumor activity. This study is focused on obtaining a 2DE protein profile for HepG2 cell line with and without
    GTT treatment. In the preliminary analysis  of the resulting 2DE profiles, 18 protein spots were found to be differentially expressed in cells treated with GTT. This observa-tion is confirmed by extending the analysis  to a larger sample size. By studying the effects of GTT treatment on differential protein expression in HepG2 cells the underly-ing mechanisms involved in the antitumor activity of GTT may be elucidated.

    Oxidative stress has been associated with postmenopausal osteoporosis which pre-disposes to risk of fracture. Palm tocotrienol is a potent antioxidant and has the poten-tial to be used for treatment of post-menopausal osteoporosis. The aim of the study is to determine if palm tocotrienol supplementation could alleviate oxidative stress in ovariectomised rat model and improve its bone strength. The rats were di- vided into four groups: (i) sham-operated  group (SHAM) (ii) ovariectomised-control group (OVX) (iii) ovariectomised and given 60mg/kg α-tocopherol by oral gavage (OVX + ATF) (iv) ovariectomised and given 60mg/kg palm tocotrienols by oral gavage (OVX + PTT). After eight weeks of treatment, blood samples were taken to measure oxida-tive status (MDA, SOD and GPX) while the femurs were biomechanically tested for strength and resistance to fracture. Ovariectomy was shown to induce oxidative stress as shown by the raised MDA levels and reduced GPX activity. Palm tocotrienols seemed to offer protection against the ovariectomy-induced oxidative stress as shown by the suppression of MDA levels and raised GPX and SOD activities in the OVX+PTT group. In comparison, α-tocopherol was only able to raise the SOD but not as high as palm tocotrienols. The biomechanical tests have shown that ovariectomy has not af-fected the bone strength significantly after eight weeks. Palm tocotrienols supplemen-tation for eight weeks was effective in preventing oxidative stress in a post-meno-pausal rat.

    Although stress among nursing staff is common, adopting effective coping styles helps in minimizing the problem. The objectives of this study were to compare stress level among ursing staff working in the above disciplines, to identify common coping style used and to determine the relationship between stress and coping styles. This cross-sectional study involved 106 nursing staff who were universally sampled from psychiatric wards and emergency departments in two public hospitals in the Klang Valley. Self-rated questionnaires i.e. Stress Arousal Checklist (SACL) and Coping inventory for Stressful Situations (CISS) were used to assess stress levels and coping styles respectively. There was insignificant difference in terms of stress level between the two nursing staffs. Stress dimension of SACL between the psychiatry (6.53 + 3.18, p=0.372) and emergency (6.02  + 2.67, p=0.372) nursing staffs were insignificant. Arousal dimension of SACL was also  insignificant between psychiatry (8.60  + 1.70, p=0.372) and emergency (9.19  + 1.61, p=0.07) nursing staff. Task coping was the most commonly used coping styles among the psychiatry (55.36  + 9.85) and emergency (57.73  + 9.87) nursing staff in this study. Stress dimension of SACL showed weak significant relationship with task coping (r=-0.313, p=0.001) and emotion coping (r=0.292, p=0.001). Arousal dimension of SACL was also found to have weak significant relationship with task coping  (r=0.271, p=0.003) and emotion coping (r=-0.251, p=0.005). While nursing was found to be a stressful profession, a significant relationship between stress and coping styles allows intervention to enable better adaptation to the stressful working environment.

    The increasing health care cost and public awareness on the delivery of high quality services has forced healthcare service providers to look into the healthcare delivery system. Clinical Pathway (CP) has been introduced in many hospitals and has been accepted as a beneficial tool in assisting healthcare organizations worldwide. Further, the CP also provides consistently high quality and coordinates services with minimum resources. It is proven to be a beneficial tool in other countries. CP is recently being introduced into the Malaysian healthcare system. The aim of this article was to high-light the benefits of CP in improving healthcare quality and controlling the medical cost. The relevant articles have been reviewed.  The majority of literature reviewed con-cluded that there were positive effects in  implementing CP. The CP was found to be significant in reducing length of stay and medical cost. The introduction of evidence based medicine, clinical outcomes, clinical audit, multidisciplinary communication, teamwork and care planning were also improved by CP. The challenges for healthcare providers and healthcare managers are to participate and be fully committed in path-way development and implementation in order to improve healthcare quality and cost control.

    Lately, increasing workplace violence is a problem that requires serious attention by the management of the healthcare sector.  This study was carried out to examine workplace violence experienced by nurses in the Universiti Kebangsaan Malaysia Medical Centre. It aimed to identify the category of nursing staff who formed the highest number of victims, the perpetrators and the common types of workplace violence. This was a descriptive cross-sectional study carried out over a three month period on 55 nurses who had participated voluntarily in this study. The demographic data and data on the violent incident were collected by using a 21-item questionnaire. The reliability and validity with Cronbach’s alpha was 0.872. Information on the most common types of violence, victims and the perpetrators was also collected. The study revealed that workplace violence among the nursing staff was 3.7% with an average of 1.2% being abused per month and one nurse being abused every other day. The study also revealed that the staff nurses were the most common victims and the perpetrators were mainly the patients (40.6%) and the  patients’ relatives (37.5%). The most common forms of violence were verbal abuse (31.9%) and verbal threat (23.7%). Physical violence was experienced by 44.4% of the victims. These results suggest that workplace violence is a serious problem which should be addressed in order to create a safe environment for the nurses.

    Drug administration is an integral part of nurses role in nursing practice. In relation to their diverse roles, nurses are required to have adequate knowledge and good practice. The purpose of this study is  to examine the level of knowledge, attitude and practice of nurses in the medical wards administering oral medication and to assess  whether nurse’s knowledge, attitude and practice is associated with working experience and professional  education (post basic training). A cross-sectional study was conducted on forty (40) nurses working in the Medical wards in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Questionnaires were used to measure the level of knowledge and attitude of nurses and a direct observation technique with checklist to record the practice of nurses. The mean score for knowledge (13.8), attitude (16.4) and practice (10.7) were all within average distribution. No significant difference was found between knowledge and practice of nurses with working experience and post basic training. However, the influence of working experience on attitude of nurses in serving oral medication was found to be significant (p= 0.045). Nurses in medical ward, Universiti Kebangsaan Malaysia Medical Centre, were found to possess an average level of knowledge and attitude in administering oral medication. In addition, this study suggest that work experience of nurses has no influence on knowledge gain and good practice in administering oral medication..

    A cross-sectional study was undertaken to evaluate if outpatient administration of in-travenous iron sucrose complex (Venofer) was a sensible option in treating iron defi-ciency anaemia during pregnancy and puerperium. A total of 120 patients with iron deficiency anaemia were recruited from the Obstetric Day Care Clinic at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) over 18 months from March 2003 to August 2004. The main outcome measures were haemoglobin increment, patients’ compliance, adverse effects and saving from hospitalization fees. The pre-treatment haemoglobin (Hb) level was 8.5+0.85g/dl for the antenatal patient and 7.6+0.80 g/dl in the post-partum group. The mean post-treatment haemoglobin increment at day four-teenth was 3.52+0.75g/dl. One patient developed skin rash while another had low-grade pyrexia. Seven patients experienced mild metallic taste. There were no serious side effects or anaphylactic reactions. Ten patients (8.3%) did not complete their ther-apy - eight delivered before completion of treatment; another two defaulted following delivery. The average number of Venofer used was seven ampoules i.e. 700mg per person, most of them required three sessions to complete the course. Outpatient treatment allows each patient to save hospitalization fees of RM45 per day, which to-talled up to RM135 for a 3-days ward stay. An estimation of RM16,200 hospitalization fees for the 120 patients was avoided during the study period. In conclusion, outpatient treatment of anaemia in pregnancy and post-partum period using Venofer was safe and feasible, with high patient compliant and cost-savings from hospitalization fees.

    Ginger extract has been reported previously by our group to exhibit anticancer and an-tioxidant effects by reducing tumour burden and lipid peroxidation respectively in he-patocarcinogenesis induced rats. The current study examined the expression of pro-apoptotic protein caspase-8 and anti-apoptotic protein Bcl-2 in hepatocarcinogenesis treated rats. Thirty normal male Wistar rats were divided into 5 groups based on the diet given: i) control (normal rat chow), ii) olive oil, iii) ginger extract (100mg/kg body weight), iv) choline deficient diet + ethionine, CDE (to induce liver cancer) and v) CDE+ ginger extract. Rats were killed at week 8, and liver tissues were excised for immuno-histochemical study to identify pro-apoptotic and anti-apoptotic proteins, caspase-8 and Bcl-2. The observation on H&E staining confirmed the CDE diet induced liver can-cer as indicated by the presence of numerous oval cells. Identification of Bcl-2 expres-sion showed that 91.6% (11/12) of the samples from the CDE group revealed positive staining while treatment with ginger extract however inhibited the expression with only 8.4% (1/12) samples showing positive staining for Bcl-2. As for caspase-8 protein, 41.7% (5/12) of the samples from CDE group showed positive staining, which in-creased to 100% (12/12) with ginger extract treatment. Our findings suggest that gin-ger extract has an anticancer effect by inducing apoptosis in liver cancer cells via up-regulation of the expression of pro-apoptotic protein, caspase-8 and down-regulation of the expression of anti-apoptotic protein Bcl-2.

    Patient education has been considered as an  integral component of care for patient after myocardial infarction. Post myocardial infarction patients require information and knowledge related to their conditions to reduce anxiety and aid recovery. The objective of this study was to identify nurses’ perception on information needs of post MI patients of UKMMC. A cross sectional study using Cardiac Patient Learning Needs Inventory (CPLNI) adopted from Timmins and Kalizer (2002) was used. It comprises seven cate-gories: related to anatomy and physiology, psychological factor, life style factor, medi-cation information, dietary information,  physical activity, and symptom management. This study was conducted in coronary care unit (CCU), coronary rehabilitation ward (CRW), medical ward 1 and medical ward 2 from January 2007 to March 2007. 56 res-pondents (96%) who fulfilled the inclusion criteria were recruited in this study. Results showed that CCU and CRW respondents ranked symptom management as their first ranking followed by medication, life style factor, anatomy and physiology, dietary in-formation, physical activity and psychological factor. However, respondents in Medical Ward 1 and 2 reported and ranked medication information as their top priorities fol-lowed by symptom management, psychological factors, dietary information, physical activity, anatomy and physiology and life style factor. There were significant differ-ences between ward nurses’ responses with their perception related to anatomy and physiology, psychology factor, life style factor, physical activity, and symptom man-agement with p value

    Patients’ satisfaction is of critical interest to all healthcare providers. Satisfied patients are more likely to seek health care and to comply with prescribed treatment regimes. The objective of the study was to identify factors that influence patient satisfaction with Emergency Department HUKM (ED HUKM). This study was conducted at ED HUKM from January 2007 till March 2007. A convenience sample of 100 participants was recruited from triage 4. The Davis Consumer Emergency Care Satisfaction Scale (CECSS) was adopted and modified. It consists of 19 questions; used a 5 point, Likert type scale of 1 to 5 (1= completely disagree and 5= completely agree) to measure patient satisfaction with triage, health care providers caring behaviours and health teaching. Results showed that 75 participants (75%) were satisfied. There were no significant difference found between male and female patients with total CESCC scores (t=0.308, p values >0.05). Pearson product moment correlation coefficients showed a positive relationship between total and subscale patient satisfaction scores, caring scores (r=0.905, p value

    Learning environment in the universities plays an important role in producing highly competent graduates especially in nursing profession. Thus, the most important as-pects are the teaching activities and as well as student – teacher interaction in daily environment in the university. To investigate the International Islamic University Malay-
    sia (IIUM) nursing students experience towards their teachers and to identify the rela-tionship between teaching and students learning perception in their learning environ-ment. This study used quantitative method and utilized two out of five subscales in Dundee Ready Educational Environment Measurement (DREEM). The subscales used
    were students’ perception of learning (SPoL) , students’ perception of teacher (SPoT)
    and total items in these both subscales are 12 and 11 items, respectively. The ques-tionnaire results revealed that IIUM nursing students scored 28.54/48.00 in (SPoL) and
    28.13/44.00 in (SPoT). Both findings showed  the IIUM nursing students’ experience their teachers and the learning environment are moving in towards positive directions. The regression finding was 51% of the total variation in students’ perception of teacher score was explained by students’ perception of learning. Although the overall sub-scales (SPoL) score in the current study falls in the category of a more positive per-ception, 2 out of 12 items were poorly scored by the IIUM nursing students. The re-searcher strongly agrees that listening to  the expression of students is an important consideration for an educational institution. The overall mean score for (SPoT) showed that the students perceived their teachers as moving in the right direction. In this pre-sent IIUM study, one item showed a mean score of less then 2.00. As a result, these two subscales most probably should reflect the same outcome such as in their aca-demic performance and experience greatly during their student life on campus. The arising issues from this DREEM study at IIUM embrace the need for the creation of supportive environment as well as designing and implementing interventions to remedy unsatisfactorily elements of the learning environment for more effective and successful teaching and learning to be realised.

    Methicillin-resistant Staphylococcus aureus (MRSA) infection is important among vas-cular surgical patients. Its effect can be devastating resulting in limb amputation and mortality. We performed a retrospective patients record analysis to determine the pat-tern of MRSA infection among vascular surgical patients in Hospital Kuala Lumpur from January 2005 to December 2007. We also attempted to identify the factors asso-ciated with poor clinical outcome after such infection. There were 999 patients who underwent vascular surgeries in HKL within  the analysis period. Of these 24 patients (2.4%) were detected to have MRSA surgical site infection. The infection was commoner among cigarette smokers, patients with diabetes melitus and those who had previous vascular surgery. Most infections occurred in the emergency surgery category and manifested as wound breakdown. Fifty-four percent of the infected pa-tients ended with graft removal, amputations or death. MRSA infection complicating vascular surgery resulted in poor clinical outcome. This serious threat requires intensi-fied preventive measures.

    In this study, functional magnetic resonance imaging (fMRI) is used to investigate func-tional specialisation in human auditory cortices during listening. A silent fMRI paradigm was used to reduce the scanner sound artefacts on functional images. The subject was instructed to pay attention to the white noise stimulus binaurally given at an inten-sity level of 70 dB higher than the hearing level for normal people. Functional speciali-sation was studied using the Matlab-based Statistical Parametric Mapping (SPM5) software by means of fixed effects (FFX), random effects (RFX) and conjunction analyses. Individual analyses on all subjects indicated asymmetrical bilateral activation of the left and right hemispheres in Brodmann areas (BA) 22, 41 and 42, involving the primary and secondary auditory cortices. The percentage of signal change is larger in the BA22, 41 and 42 on the right as compared to the ones on the left (p>0.05). The average number of activated voxels in all the respective Brodmann areas are higher in the right hemisphere than in the left (p>0.05). FFX results showed that the point of maximum intensity was in the right BA41 whereby 599±1 activated voxels were ob-served in the right temporal lobe as compared to 485±1 in the left temporal lobe. The RFX results were consistent with that of FFX. The analysis of conjunction which fol-lowed, showed that the right BA41 and left BA22 as the common activated areas in all subjects. The results confirmed the specialisation of the right auditory cortices in pro-cessing non verbal stimuli.

    This is a report of a patient on multiple antipsychotic medications for the treatment of schizophrenia. Often, polypharmacy is not encouraged, however, with the advent of newer atypical antipsychotic agents, this practice may need review. This case will be used to highlight the rare instances when polypharmacy may be useful prior to the commencement of clozapine for the treatment of schizophrenia.

    Stroke is becoming a major public health issue in our country due to the fact that there isan increasing life span of our population. Due to advancement of acute management of stroke, three out of four people will survive beyond the acute phase of stroke. Stroke careproviders are still debating regarding the exact period of the terminology ‘longer-term stroke’; however many agreed that long-term of stroke refers to the period of one year and thereafter as this period is the determinant for longer-term survival. Management beyond the first year of stroke is complex, encompasses all aspects of patient’s life; physical, psychological and integration into community. Rehabilitation being the cornerstone of longer-term stroke management should now focused on more evidence-based approach as to be effective and relevant to the stroke patients.
