    Schizophrenia poses challenges in diagnosis and treatment strategies when the predominant clinical features represent another spectrum of disorder like eating disorders. Nevertheless, symptoms of eating disorder in schizophrenia are not entirely uncommon although never included in the diagnostic criteria. We reported a case of a woman who first presented at seventeen years old with food refusal and underlying psychosis resulting in severe weight loss, but defaulted treatment for almost a decade. In 2009, she presented again with sinus bradycardia and secondary amenorrhoea. In this report, we discussed about the patient’s vulnerability for psychosis and its psychodynamic drive which led to a complex symptoms manifestation. Our aim is to highlight its diagnostic dilemma and suggestions to treatment strategies unique to this presentation.

    Objectives: To study relationship of depressive symptoms to hypertension. Methods: A cross sectional study was carried out on respondents from Kampung Awal. Hypertension was defined as self-reported or by measurement using a mercury sphymomanometer and depressive symptoms were evaluated by CES-D scale. Results: A total 103 respondents were studied. The male:female ratio was 1:1.5 with mean age of 41.8 years. Majority had formal education up to secondary school. 45% were government servant and over 95% subjects had income of RM1000 or less per each family member per month. 21.4% (n=22) self-reported to have hypertension and 7.8%(n=91) met the criteria for incident hypertension. 7.8% met the criteria for both. Mean score based on CES-D was 13.08. 32.0% subjects had depression. 54 subjects reported never experienced any strain for past 6 months and 24 reported to have 2 or more .61 subjects were overweight with mean value of BMI=26.19 kg/m2. Self-reported hypertension and incident hypertension were strongly associated with age but only selfreported hypertension was strongly associated with overweight. However, there was no significant association between hypertension with chronic strains and depressive symptoms. Conclusions: Depressive symptomatology was not associated with hypertension in this survey. Women had a significant risk in having depressive symptoms. Age =45 years & overweight were significant risks for hypertension. A prospective study will be more useful in the future to find out the association between depression and hypertension.

    Objective: This study intended to determine the prevalence of anxiety and depressive symptoms and to compare their severities among rural residents based on their socio-demographic variables. Methods: A cross sectional study was conducted among 520 residents in East Coast Peninsular Malaysia who completed the Malay Hospital Anxiety and Depression Scale (HADS). Data were analyzed with SPSS 17.0, whereby descriptive statistics and nonparametric tests were utilised for scores comparison. Results: The prevalence of mild anxiety and depressive symptoms was at 12.90% and 11.30% respectively. Statistically significant associations between gender and monthly income with anxiety and depressive symptoms were observed (p < 0.01). Conclusion: Findings in our study indicated that the prevalence of anxiety and depressive symptoms among rural residents was low. Nevertheless, females and those with higher education (> PMR) background were comparatively more prone to these mood disorders. Healthcare professionals should be constantly alerted to these tendencies in the process of providing medical services especially in rural areas.

    This two-phase study examined the prevalence of depressive disorders among married working women in a sub-urban area in Malaysia. The Malay version of the General Health Questionnaire-12 (GHQ-12) was used for initial screening. Using multistage cluster sampling, there were 700 subjects from 25 workplaces that were approached, of which 307 filled out GHQ-12 in the initial phase. The prevalence of psychological distress (GHQ 2/3 cut off) is 22.8% (n=70, 95% CI 18.1-27.5). In the second phase, all 49 consenting patients who were screened positive for severe psychological distress (GHQ 3/4 cut off point) were telephone-interviewed by a trained psychiatrist with the Malay version of Mini International Neuropsychiatric Interview (M.I.N.I) to diagnose depressive disorders. The prevalence of depressive disorders was 5.5% (n=17, 95% CI 3.5-7.5). The prevalence of depressive disorders is comparable to those found in the working population worldwide.

    Caring for a family member with dementia is associated with distress and several caregiver factors are known to be determinants of burden of care.
    Objective: To determine the relationship between the caregivers’ sociodemographic variables and their perceived burden of care. 
    Methods: Patients diagnosed as having dementia with their caregivers were selected through a non-randomised sampling method from the psychogeriatric and memory clinics in Universiti Kebangsaan Malaysia Medical Centre and Hospital Kuala Lumpur. Burden of care was assessed using the Zarit Burden Interview.
    Results: Age, gender, educational achievement, ethnicity and kinship of the 65 caregivers did not show any significant statistical difference in relation to their perceived burden. Conclusion: Burden in caring after patients with dementia was not significantly determined by the sociodemographic characteristics of their caregivers

    Objective: To study the demographic data of patients and the pattern of crime in the study group, to look at the outcome of assessment by psychiatrist on fitness to plea and insanity at time of offense and to assess association between the nature of crime with presence of psychopathology during the crime. Method: This is a retrospective study. All available case notes for 342 forensic admissions from January 2007 until March 2010 were reviewed. All related information on 135 patients that committed violent crime was taken for analysis. Result: Majority of patients were male, Malay, single, education up to secondary school and unemployed. Only 38% of patients had encountered psychiatric services, 20% had previous imprisonment and 49% had history of substance usage. In cases involving victims (87%), 64% the victims were known to the patient, 53% had hallucination or delusion or both at the time of crime and 90% was found to have some diagnosis of mental illness after psychiatrist assessment. Only 81% of formal forensic reports were available in the case note and it showed 94% were fit to plea and 82% were at sound mind at the time of offense. Conclusion: Substance abuse had high prevalence among the patient. Almost 2/3 never had any encounter with psychiatric services before the admission. Even with the high percentage of patient diagnosed with mental illness, they were still found to be fit to plea in court and are at sound mind at the time of offense

    Objective: To assess psychiatric morbidity, personality profiles and saliva cortisol levels in overweight and obese individuals at dietician clinic. Method: This cross-sectional study is based on individuals who attended dietician clinic between June to November 2008. They had completed questionnaires that included General Health Questionnaire 30-items, assessment for psychiatric illness using Structured Clinical Interview for DSM-IV and personality profiles using Personality Assessment Schedule. Saliva and body mass index were taken. Results: Of the 102 patients, 16 (15.7%) were diagnosed to have psychiatric illness. There were no differences between obese and overweight patients in terms of personality traits and psychological problem. Presence of psychiatric illness was associated with higher mean body mass index. Saliva cortisol levels were not elevated in patients who had psychiatric illness. Conclusions: Psychiatric illnesses are common in individuals who seek weight treatment. Careful psychological evaluation is important at (or before) commencement of a diet program.

    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.

    Background: Many proteins released by cells to the blood and other fluids are glycoproteins. One set of glycoproteins carry the ABO blood group determinants and glycoproteins have been shown to be vital in determining the structure and organization of plasma membranes. There is evidence suggesting their important role in cell-to-cell contact, adhesion, hormone interaction and vital transformation. Differences in proteins and glycoproteins in the different human blood groups may influence the invasion process of Plasmodium falciparum. The objectives of the study were to determine whether there are any changes in proteins and glycoproteins of red blood cells upon infection by P. falciparum and whether these protein and glycoprotein changes differ in the various ABO blood groups.

    Methods: A Malaysian strain of P. falciparum was cultured in vitro in red blood cells from A, B, O and AB blood groups. Protein and glycoprotein profiles of uninfected and P. falciparum- infected red blood cells from the different human ABO blood groups were analyzed by SDS-PAGE. For protein bands, the gels were stained with Coomassie blue while glycoproteins were visualized following staining of gels using GelCode ® Glycoprotein Staining Kit.

    Results: Cell membranes of P. falciparum infected erythrocytes from different ABO blood groups have different glycoprotein profiles compared to uninfected cells. All the infected samples showed a prominent protein band of molecular weight 99 kDa which was not present in any of the uninfected samples while a 48 kDa band was seen in four out of the seven infected samples. The erythrocyte cell membranes of A and AB blood groups showed different glycoprotein profiles upon infection with P. falciparum when compared to those from blood groups B and O.

    Conclusion: The two glycoproteins of molecular weights 99 kDa and 48 kDa should be further studied to determine their roles in the pathogenesis of malaria and as potential targets for drug and vaccine development.

    Background: Database on hospital records like discharge data, birth and death certificates are widely used for epidemiological and research studies. However there are a very few validation studies on these data. The aim of this study was to validate and assess the accuracy of the ICD 10 database on congenital anomalies in the state of Penang. This study was carried out for three years, from 2002 to 2004.

    Methods: The list of cases coded under the general coding “Q” was extracted and approximately 30% of cases were randomly selected from the list. Medical records for the selected cases were checked and discrepancies for the diagnoses between the medical records and the ICD 10 data base were recorded for three years. Verification was done for basic demographic variables and the coding of the diseases. Discrepancies, sensitivity and specificity were calculated.

    Results: The ICD 10 database for congenital anomalies are classified into two types: Type 1 and Type 2. Discrepancies on demographic information were found among the age of patients (babies with congenital anomalies). In Type 1, there was a discrepancy of about 0.02 % to 0.05% probability that a congenital anomaly case can be recorded as non congenital anomaly in the ICD 10. In Type 2 there was a discrepancy that a non-congenital anomaly was classified as congenital anomaly and this ranged from 26.7% to 50.0%. The sensitivity ranged from 96.85% to 97.98%, thus it can be concluded the ICD 10 database is highly sensitive while the specificity ranged from 50.00% to 78.57 %. In other words the ICD 10 is not accurate when classifying the non- congenital anomaly cases. A fair percentage of non-congenital anomaly cases were classified as CA in the ICD 10 database.

    Conclusion: Even though hospital databases are used as a baseline data for a number of research and epidemiological studies it cannot be used at face value. Validation of these data is necessary before any conclusions can be drawn or intervention measures are undertaken.

    Background: Clinical clerkship in a busy hospital environment forms an important part of undergraduate medical training. Regular objective assessment of this activity with feedback would be expected to improve outcome.

    Methods: We implemented fortnightly clinical assessments using modified OSLER (Objective Structured Long Examination Record), and over a 6-week clinical rotation. Modifications included provision of individualized feedback. The assessment process was evaluated by both students and teachers via a questionnaire measuring their perceived educational impact, feasibility and acceptability.

    Results: Students agreed that the patient spectrum was appropriate and fair, resulting in improved history taking and presentation skills (96.6%), clinical examination skills (89%) and clinical reasoning skills (90.7%). It was graded to have helped learning “tremendously” and “moderately” by 64.7% and 32.8% of students respectively. Perceived improvement was attributable mainly to the repetitive nature of the assessments since only 63% of students were provided with feedback. 96.6% of students and 94.1% of assessors perceived the format created a stressful but positive learning environment. 52.9% of assessors agreed that the exercise consumed significant time and resources but 88.2% rated it as manageable and supported its continuation.

    Conclusion: Frequent and regular in-course clinical assessments with emphasis on individual feedback is feasible, acceptable and has significant positive educational impact.

    Morning surge in blood pressure is an independent cardiovascular risk factor in the middleaged and the elderly. Whether such a surge occurs in young subjects is not known. Eighty normotensive subjects (age: 21.8 ± 1.3 yr) measured their own blood pressure (BP) using an automatic device (Omron HEM-7080,) on going to bed and on waking up, for 2 consecutive days. In contrast to large morning BP surges reported for older age groups, there was much smaller but significant (P

    Background: The importance of tooth sectioning is realized in disasters such as earthquake, airplane crash investigation, terror, micro leakage studies, age estimation etc. The objective of this study was to develop a simple method to make thin sections (approximately 100 mm) from freshly extracted teeth.

    Methods: One hundred and twenty human premolars recently extracted for orthodontic purpose were used for this study. The teeth were stored in 0.5% chorlaramine for 2 weeks and were not allowed to dry at any stage of the experiment. The teeth were thoroughly washed in distilled water teeth and then were sectioned buccolingually from crown to the root portion.

    Results: A detailed embedding-cutting-mounting procedure is described. The prepared thin ground sections were then examined under a Polarised light microscope for the enamel and the dentine, as well as the caries lesions can clearly be distinguished.

    Conclusion: This is an effective and efficient method for preparation of ground sections in which the hard tissue details are preserved.

    Metabonomics can be used to quantitatively measure dynamic biochemical responses of living organisms to physiological or pathological stimuli. A range of analytical tools such as high-resolution nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) combined with multivariate statistical analysis can be employed to create comprehensive metabolic signatures of biological samples including urine, plasma, faecal water and tissue extracts. These metabolic signatures can reflect the physiological or pathological condition of the organism and indicate imbalances in the homeostatic regulation of tissues and extracellular fluids. This technology has been employed in a diverse range of application areas including investigation of disease mechanisms, diagnosis/prognosis of pathologies, nutritional interventions and drug toxicity. Metabolic profiling is becoming increasingly important in identifying biomarkers of disease progression and drug intervention, and can provide additional information to support or aid the interpretation of genomic and proteomic data. With the new generation of postgenomic technologies, the paradigm in many biological fields has shifted to either top down systems biology approaches, aiming to achieve a general understanding of the global and integrated response of an organism or to bottom up modelling of specific pathways and networks using a priori knowledge based on mining large bodies of literature. Whilst metabolic profiling lends itself to either approach, using it in an exploratory and hypothesis generating capacity clearly allows new mechanisms to be uncovered.

    Talc’s softness, whiteness, lamellarity, inertness and affinity for organic chemicals make it valuable for industrial and domestic applications. The largest consumers are the paper and ceramic industry; only 5% is used as cosmetics. It is also used for preserving animal feed, and a carrier for drugs, insecticides, pesticides and chemicals. Talc was introduced as baby powder in 1894 and advertised aggressively worldwide. Widespread and indiscriminate use soon raised concerns about its implications for health. The IARC found that talc containing asbestiform fibres is carcinogenic to humans, but inadequate evidence to implicate talc not-containing asbestiform fibres. Pulmonary manifestations of talc inhalation include talcosis, talcosilicosis, and talcoasbestosis. Drug-users administering talc-adulterated oral medications intravenously develop pulmonary granulomas, fibrosis and irreversible pulmonary hypertension. Worldwide reports reveal talc inhalation is fatal to infants; it coats and dries mucus membranes, causes hemorrhage, edema, desquamation of bronchial epithelium, and clogs and compromises mucociliary clearance; larger quantities completely obstruct airways. Progressive diffuse pulmonary fibrosis is a recognized sequel to massive aspiration of baby powder. IARC has classified perineal use of talcum powder as a possible ovarian carcinogen, while a recent study has found that perineal talcum powder increases the risk of endometrial cancer among postmenopausal women. There is a need to raise public awareness of the serious risks associated with the use of talcum powder and for legislation to protect the health of the uninformed who represent the poorer segment of the community, and infants and young children. The dangers associated with cosmetic use of talc outweigh any possible benefits.

    Acute appendicitis is an infrequent yet the commonest surgical emergency in pregnancy occurring in about 1:1500 pregnancies. The classical abdominal pain in the right lower quadrant of the abdomen is the only reliable clinical sign. Delay in diagnosis is attributed to presence of symptoms commonly seen in pregnancy like nausea and vomiting and difficulty in localizing abdominal pain due to displacement of the appendix with advancing gestation. Perforated appendix and generalized peritonitis impacts adversely on pregnancy contributing to increases in miscarriage, pre-term delivery, fetal loss and even maternal mortality. Imaging studies like abdominal ultrasonogram, helical computerized tomography and magnetic imaging have been utilized to complement clinical suspicion and decrease ‘negative appendectomies’ but robust data on their routine use is awaited. Although the laparoscopic approach is a useful diagnostic and therapeutic tool in early pregnancy, its use as the primary approach for appendicectomy in pregnancy requires further evaluation as increases in the incidence of fetal loss of 5.6% has been reported compared to 3.1% in open access surgery

    Physical inactivity is strongly associated with obesity and an increased risk of cardiovascular disease in children and adolescents. A cross-sectional study using multistage random sampling was conducted to determine associations between demographic characteristics, sedentary behaviours and physical activity among adolescents. Data were collected from 785 (414 males and 371 females) Form four students attending 15 schools in Petaling District, Selangor using an adapted self-administered questionnaire. Results showed that more females (50.1%) were physically inactive compared to males (39.6%) (Adjusted odds ratio (OR): 1.55, 95% confidence interval (CI): 1.12-2.15). Physically inactive adolescents were less likely to participate in intramural/house league sports (OR: 1.71, 95% CI: 1.19-2.44), school team sports (OR: 1.45, 95% CI: 1.03-2.04) and individual physical activities outside school (OR: 1.53, 95% CI: 1.11-2.12) compared to their physically active counterparts. Physically inactive adolescents were also less engaged in sedentary activities, such as television watching (OR: 0.69, 95% CI: 0.50-0.94), playing computer/video game (OR: 0.44, 95% CI: 0.28-0.72), talking on the telephone/mobile phone text messaging (OR: 0.47, 95% CI: 0.32-0.69) and reading (OR:0.45, 95% CI: 0.24-0.86) compared to those who were physically active. In this study, physical activity coexists with sedentary behaviour in adolescents. Sedentary activities may not necessarily displace physical activity among youth. In addition, these data suggest that promoting organised sports in school and outside the school among youths may be a potential strategy for increasing physical activity in this population.

    Introduction: The purpose of the present study was to investigate exploratory factor analysis of the
    Beck Anxiety Inventory (BAI) and reports its reliability and validity in Malaysia. Method: One thousand
    and ninety participants from four different samples (namely students, general population, medical and
    psychiatric patients) completed the Malay version of Beck Anxiety Inventory, as well as additional
    questionnaires such as Fear Questionnaire, Anxiety Sensitivity Index, Depression Anxiety Stress Scale, and Catastrophic Cognition Questionnaire. Results: Exploratory factor analysis revealed a three factor solution and accounted for 48.01% of the total variance. The three-factor structure appeared to be; subjective anxiety, autonomic, and neurophysiology. The Cronbach alpha coefficients (α) ranged from 0.66 to 0.89 with satisfactory overall alpha value (.91). Evidence was also found acceptable concurrent validity of the BAI-Malay (range between r=.22 to r=.67). Conclusion: This study shows that the BAIMalay is a reliable and valid instrument to measure symptoms of anxiety in the Malay population
    and can be used in research and clinical service in Malaysia. However, replication of study by using
    confirmatory factor analysis and application of the instrument among anxiety patients worth of further
    investigation.
