    Red cell alloimmunisation is defined as the development of antibodies in response to foreign red cell antigens through transfusion or pregnancy. In pregnant women even without the history of previous blood transfusion, this is possible through previous or current pregnancy with the presence of paternal red cell antigen inherited by the fetus. This study was aimed to determine the prevalence of red cell alloimmunisation among pregnant women without previous history of blood transfusion and the association with number of pregnancy and history of obstetric complications. This was a cross-sectional study in which 150 pregnant women were randomly selected from the antenatal clinic. Ten mls of peripheral blood was obtained for antibody screening using indirect antiglobulin test besides the routine antenatal screening. In this study, the majority (37.3%) of the women were primigravidae. Red cell alloantibodies were detected in two out of 150 (1.3%) patients which were subsequently identified as anti-C and anti-D. However none of the primigravida was alloimmunised. One woman of gravida 2 (2.9%) and gravida 3 (3.6%) each were positive for alloimmunisation. One of them also had a bad obstetric history. This study showed that the prevalence of red cell alloimmunisation among pregnant women was low in this centre. Nevertheless, red cell alloantibody screening test should be made available to reduce possible complications of alloimmunisation in mothers and fetuses.

    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

    Reactive arthritis and erythema are uncommon presentations of tuberculosis (TB). Reactive arthritis in tuberculosis (TB) is known as Poncet's disease, a rare aseptic form of arthritis observed in patients with active TB. We report a case of Poncet's disease in a 20-year old man whose reactive arthritis overshadowed other clinical symptoms of TB resulting in delayed diagnosis and treatment. Although a conclusive diagnosis of Poncet's disease is not possible, reactive immunologic reactions such as reactive arthritis and erythema nodosum even without respiratory symptoms should raise suspicion on possible TB. Thus, taking a thorough medical history as well as performing relevant examinations and investigations for possible TB will help expedite the diagnostic process.

    Radiation retinopathy (RR) is a known complication after radiotherapy for Nasopharyngeal Carcinoma (NPC). This study aims to relate the relationship of RR and radiation dose in patients with NPC through assessment with clinical
    funduscopy and fundus fluorescein angiogram (FFA). A cross sectional study was conducted on patients with NPC who had completed radiotherapy treatment in the Oncology Clinic, Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Eighty two eyes of 42 patients were examined and the prevalence of RR was found to be 35.4%. The severity of RR is strongly associated with the dose of radiation to the retina (Spearman correlation value=0.48; p<0.001). The common features of RR assessed by FFA were telangiectatic vessels (26.2%) and capillary non-perfusion (14.3%). Retinal neovasularization occurred in 10.7% of eyes. The level of visual deterioration correlated with the severity of RR with 26% of eyes experiencing a visual acuity of 6/18 or worse. More than one third of patients developed RR, with radiation maculopathy being the commonest cause for significant visual loss. FFA is a useful tool in detecting early signs of radiation retinopathy and maculopathy.

    Introduction: Nasopharyngeal Carcinoma (NPC) is the second most common cancer among men in Malaysia. Establishing local data will help to improve the treatment strategies and lower the anxiety and depression level among NPC patients. Our aim was to compare the level of symptoms of anxiety and depression and the coping strategies employed between NPC and cancer-free patients. Methods: A comparative cross-sectional study with universal sampling was conducted on 22 NPC patients and 30 cancer-free patients from the Oncology and Radiotherapy Department and Ear, Nose and Throat clinic of Hospital Kuala Lumpur (HKL) between 12 to 29 May 2008. In this study, the symptoms of depression and anxiety were obtained by using the Hospital Anxiety and Depression Scale (HADS) while Brief COPE questionnaire was used to understand patients’ coping strategies. Results: The prevalence of NPC was higher in the Chinese, men, aged between 40 and 59 years, and those from the lower income group. The levels of anxiety and depression symptoms were found to be higher in the NPC group as compared to the cancer-free group. However, only the level of depression was found significantly related to the NPC group (p=0.002). This study also found that the two comparison groups were
    using different types of coping strategies. The NPC patients mainly used ‘acceptance’ as their coping strategy while the comparative group most often used ‘religion’. Among the types of coping strategies reported by the patients, ‘use of instrumental support’ type was found to be associated with a lower level of anxiety (p = 0.035) and ‘humour’ type was associated with lower depressive symptoms (p = 0.269). On the contrary, ‘selfblame’ type was associated with both anxiety (p =0.0001) and depression (p = 0.001) symptoms. In addition, patients with different gender, ethnicity, educational levels, and
    monthly income were also found to have significant differences in their levels of anxiety and depression as well as type of coping strategies. Conclusions: NPC patients had higher anxiety and depression levels as compared to the comparative group. Different socio-demographic backgrounds and different types of coping strategies had an influence on patients resulting in different levels of anxiety and depression.

    The aim of the study was to acquire background information on computer literacy among schizophrenia patients in Kota Bharu, Malaysia, prior to the introduction of a computerised cognitive remediation programme in the local setting.
    Method: Fifty consenting consecutive patients with schizophrenia attending the Universiti Sains Malaysia Hospital psychiatric clinic were surveyed using the Computer Literacy Scale (CLS), a scale designed to specifically look at their level of computer knowledge, confidence and attitude towards computers.
    Results: The majority of the patients studied have had schizophrenia for 5 years or less. While the majority of them have used computers befoie, about half had a poor level of knowledge, although they showed reasonable confidence and a positive attitude towards computers. Few played computer games.
    Conclusions: Implementation of a computerised cognitive remediation programme in the Malaysian setting has a promising potential based on the results of this study but the programme needs to be adapted in light of the negative attitudes towards the use of games.

    A study was conducted to evaluate the extent of sleep problems among children aged between 6 to 15 years old who were followed up at Penang Hospital Paediatric Clinic for various neurological disorders and compared to those with other paediatric illnesses and their healthy siblings. A parental questionnaire was used to assess sleep problems in 48 children with neurological disorders and compared to 46 of their healthy siblings, 59 children with non-neurological paediatric illnesses and 67 of their healthy siblings. Sleep problems were clustered into five subscales: bedtime difficulties, parental involvement at time of sleep, sleep fragmentation, parasomnias and daytime drowsiness. Children with neurological disorders had significantly more sleep problems than did their siblings, those with non-neurological paediatric illnesses and their healthy siblings (p < 0.001). This was particularly so in areas of bedtime difficulties (p>0.001), the amount of parental involvement (p

    Objective: Self-esteem is an important component of psychological health. In Malaysia, Rosenberg’s self-esteem scale remained the single most popular utilized scale for studying global self-esteem. This study aims to design a language, culture and illness specific self-esteem questionnaire. Methods: The study consisted of 2 phases. The first phase was to generate items for the new self-esteem questionnaire (SSES) in Bahasa Malaysia. Literature review on the concept of selfesteem and its’ content was conducted. This was followed by expert opinion from professional care-givers. The items were qualitatively validated by healthy subjects and patients with schizophrenia from the same locality, culture and language. The second phase consists of quantitative validation of the items. Items in the new scale were analyzed based on the responses from 165 stable schizophrenia outpatients. The validated Malay version of Rosenberg Self-Esteem scale (RSES) was used concurrently as a comparison. Results: The SSES displayed good internal consistency for its two domains
    (Cronbach’s alpha=0.88, 0.81) and test-retest reliability (ICC), ranged from 0.44 to 0.87. Its construct validity was confirmed by confirmatory factor analysis. The concurrent validity of SSES and RSES using Pearson correlation was 0.77. The Cronbach’s alpha for the validated Malay version of RSES is 0.67. Conclusion: This study presents a new self-esteem questionnaire (SSES) which has high concurrent validity with the standard RSES and confirms the reliability and validity of SSES in Malay patients with Schizophrenia.

    Objective: In Malaysia, opioid abuse is an acknowledged problem with severe health and economic repercussions. Until recently, drug addicts were mainly criminalised and forcefully rehabilitated in correctional facilities. However, the high relapse rates of this approach, coupled with the high rates of blood borne infections among drug users, led to increasing acceptance of a healthcare-based approach in the rehabilitation of drug addicts. Methadone was among the medications introduced as substitution maintenance therapy in 2005 and Universiti Malaya Medical Centre (UMMC) is a centre for MMT. This study aimed to determine the effects of MMT on quality of life in patients here. Methods: The sample was 46 patients who attended the Psychiatric outpatient clinic in fill in UMMC. The instrument used to assess quality of life was the WHOQOL-BREF. Results: The study design was cross-sectional with retrospective elements. Baseline QOL scores were obtained from case records and follow-up scores from the month of September 2007. Statistically significant improvements in all four domains of WHOQOL-BREF were found.

    Objective: A study was conducted at the Universiti Kebangsaan Malaysia Medical Center (UKMMC) adult psychiatric clinic from June 2006 to December 2006. The aim was to assess the rate of the metabolic syndrome in a group of outpatients with mood disorders and schizophrenia and also to determine the relationship of this condition with sociodemographic factors and psychiatric illness characteristics.
    Methods: A total of 51 subjects agree to participate of which 100 were approached. The International Diabetes Federation (IDF)(2005) criteria are used for the diagnosis of metabolic syndrome and Diagnostic Statistical Manual Version IV (DSM-IV) criteria are used to made psychiatric diaognosis.
    Results: The prevalence of metabolic syndrome was found to be 37.2% and was significantly higher amongst mood disorders patient. However the metabolic syndrome is not associated with the anti psychotic therapy (p=0.41).
    Conclusion: This study suggests that it is important for the psychiatrist to monitor metabolic syndrome in any of their patients.

    In a retrospective analysis of paediatric referrals to a Neurology outpatients clinic, the largest single category of 47 patients (32%) presented with acute recurrent headache. There were 30 girls and 17 boys. Using conventional criteria 43 of the children could be classified as classical migraine ( 10 ), common migraine (20), basilar migraine (3), opthalmoplegic migraine (1) and tension headache (9). The 9 children with tension headache, all girls, had pain char-acteristics distinct from the rest, but in terms of severity and duration of headache attacks ,were similar to those with classical migraine, which is against the theory that tension headache and migraine are at different ends of the spectrum of the same process. These findings are consis-tent with recent adult data, but have not been noted in paediatric work. (Copied from article).

    This is a retrospective and descriptive study of 30 children and adolescents with conduct disorders diagnosed for the first time this year (1993) at the Child and Family Consultation Unit, UKM. Eleven of them were diagnosed to have a Socialized Conduct Disorder, 8 had symptoms of Unsocialized Conduct Disorder, whilst 4 had Conduct Disorder confined to the family context. Another 5 had Depressive Conduct Disorders while 2 had features of other mixed disorders of conduct and emotions. Most them were boys and were ten years old and above. The majority presented with at least one year history of illness and school authorities played an important role in being the main referral agency. Prominent abnormal psychosocial situations were inadequate or inconsistent parental control and discordant intro familial relationships. Socio-economic status and geographical differences were associated with the prevalence of the disorder. The main symptomatology found were disobedience and frequent lying, stealing, truancy and fighting or bullying.

    Objective: To audit the amount and complexity of case load and the waiting time for orthodontic treatment in Orthodontic Department of Universiti Kebangsaan Malaysia (UKM).
    Materials and Methods: This study involved three waiting list records in Orthodontic department, UKM and 484 patients’ record were selected using Random Sampling technique. Demographic data of the patients were noted. Data on date of patient’s visit to ‘Klinik Rawatan Utama’ (KRU), Screening clinic and first orthodontic treatment (removable/fixed) clinics were also recorded. The severity of referred cases were graded using complexity scale (Russle et al, 1999).
    Results: Patients were mostly female (76%) with age ranging from 10 to 52 years old. 75% of the referred cases were complex cases. From the year 2002-2007, 35% were referred for removable and 65% were referred for fixed clinic. In average, orthodontic screening waiting time was 6.9 ± 2.5 month. Patient would received removable and fixed appliance treatment after 4.4 ± 1.0 months and 14.5 ± 9.8 months respectively.
    Conclusions: Most patients were referred to fixed waiting list. The waiting time from 2002 until 2007 for orthodontic treatment in UKM was longest for fixed followed by screening. The shortest waiting time was for the removable treatment.

    This is a retrospective descriptive study done to look at common presentation and method of detection of breast cancer. A total of 366 case records of patients attending the Breast and Endocrine Clinic at Hospital Kuala Lumpur were reviewed. The peak age of breast cancer presentation was 40 to 49 years (39.6%). Most (81.4%) patients presented with a lump in the breast and the lump was mainly self-detected (97.3%). The mean tumour diameter on presentation was 4.7± 3 cm. Medical staff detected the disease in 1.6% cases and 1.1% of cases were detected by mammogram. Most women detected the lump themselves, suggesting that Breast Self Examination (BSE) can be used for detection of the disease in places where there is cost and availability constrains for mammogram. Early detection with BSE can possibly offer better treatment options and quality of life despite the evidence that it does not reduce the mortality due to breast cancer.

    A proportion of patients with acute viral fever with thrombocytopaenia does not necessary have dengue infection. Managing them indiscriminately as dengue infection may not be appropriate. The prevalence of this problem is not exactly known. The objective of this study is to determine the prevalence of acute non-dengue febrile thrombocytopaenia among adult patients presenting with acute non-specific febrile illness in an outpatient setting. This was a clinic-based cross sectional study. Consecutive patients presenting with non-specific febrile illness of less than two weeks were selected from the Primary Care Centre of Hospital Universiti Kebangsaan Malaysia (HUKM) and the Batu 9 Cheras Health Clinic. Full blood count was done on the day of visit and dengue serology was done on day five of illness for all patients enrolled. Seventy three patients participated in this study from May to November 2003. Among the patients, 35 (47.9%) were noted to have thrombocytopaenia. Fourteen (40%) patients with thrombocytopaenia were serologically negative. The prevalence of non-dengue febrile thrombocytopaenia was 19.2%. A significant number of patients with acute non-specific febrile illness with thrombocytopaenia were negative for dengue serology. These patients should be differentiated from those with acute febrile thrombocytopaenia, as they might differ in their natural history from those with dengue infection, and hence require different management strategies.

    A study to determine average knee laxity in the Malaysian population and how it affects daily living was conducted at the University Malaya Medical Centre between January and April 2004. Fifty two male and 76 female subjects were recruited for this study, all of whom were healthy volunteers with no ambulatory problems. Side to side knee laxity testing was performed using a KT-1000 arthrometer. Significant differences in knee laxity were noted among different races and between sexes. For instance, overall, Chinese and female study participants had higher knee laxity: (left knee, 2.17 mm (SD=1.30) and right knee was 2.88 mm (SD= 1.51)). On average, the difference between knees was 0.70 ± 1.26 mm (less than 1 mm) which is a smaller variation than reported in previous studies which suggested 3 mm. Despite finding knee laxity ranging from 0 to 8mm, no correlations were found between Lysholm, IKDC and Tegner knee outcome scores and the degree of knee laxity. No other predictors such as height, weight and age correlated with levels of knee laxity. We therefore conclude that knee laxity is a common occurrence in the normal population and is therefore not suitable as a sole predictor of knee function and should not be used as the only criteria for surgical intervention.

    Heart failure is chiefly the end stage of primary hypertension and a major public health problem in Malaysia. The aim of this work is to investigate the level of BNP that may discriminate between primary hypertension patients without heart failure and primary hypertensive patients with heart failure. This study was conducted on 60 hypertensive patients without any clinical symptoms of heart failure referred for echocardiography to evaluate the ventricular function. Patients with metabolic diseases and terminal diseases were excluded from the study. The BNP levels were assessed using the Triage Meter from Biosite Diagnostics. Results showed that BNP level display a negative correlation with ejection fraction (Pearson correlation test). The significant result (paired t test, p < 0.05) proves that both predictors are very important and relates to each other. Low ejection fraction is significantly marked with raised BNP level suggesting that BNP may play potential role as screening tool for early detection of heart failure in primary hypertensive patients.

    The objective of this study is to determine the prevalence and factors associated with psychosis in Parkinson’s disease (PD) patients.
    Method: This is a cross-sectional study of 108 PD patients from neurological clinic UKM Medical Centre and Kuala Lumpur Hospital. The patients were recruited from August to December 2004. Psychosis was determined using SCID, the severity of psychosis was rated using BPRS. The cognitive functions were evaluated with MMSE and the severity of depression was assessed with HAM-D.
    Results: The result shows that the prevalence of psychosis in Parkinson's disease patients in this sample was 13%. The psychosis was found to be significantly associated with advancing age, duration of illness, severity of depression and cognitive impairment. Multivariate analysis demonstrates that severity of depression (OR = 1.08, 95% C.I. = 1.01 - 1.16) and advancing age (OR = 4.72, 95% C.I. = 1.37 - 16.29) increased risk of psychosis in PD patients.
    Conclusion: We found that advancing age and severity of depression increase risk to develop psychosis in patients with PD.

    This retrospective study was conducted at the audiology clinic of UKM in the year 2000. It was intended to detect the effect of walkman on the hearing system of its users and to investigate whether distortion product otoacoustic emission test can provide an early and reliable sign of cochlear damage or not. Distortion product otoacoustic emission test helps to determine the function of outer hair cell. Outer hair cells get damaged with exposure to loud sound, drugs and aging. Thirty subjects (20 in the study group and 10 in the control group), between the ages of 19-25 years, who fulfilled all the criteria of selection, were investigated. There were two sets of criteria (general and specific). Anyone, in the control or study group, failing in any of these criteria was excluded from the study. According to the general criteria, it was essential for all the subjects to have clean ear canals, normal hearing at all the frequencies (250Hz- 8000Hz), normal middle ear function (Type A tympanogram), no middle ear problem, not used/using any ototoxic medicine, no family history of hearing loss, no history of ear surgery, not exposed to any form of loud noise like disco, concert, F1 racing or gun shooting. According to the special criteria it was essential for the subjects in the control group to have never used a walkman and those in the study group must have been using a walkman for at least 6 months. Comparison of distortion product emission levels between control and study groups revealed that emissions were significantly lower in the study group, across all the frequencies, suggesting outer hair cell damage in the walkman users. These differences reached level of statistical significance (p<0.05) at 2, 4, 6 and 8kHz. Using walkman at an intensity unsafe for hearing and a duration longer than recommended is suspected for the outer hair cell damage in our study group. Those using walkman for longer duration and higher intensity manifested much lower emission levels. Our study supports the literature that distortion product emission test is a much sensitive test than pure-tone audiometry, as it can detect cochlear damage long before it appears in an audiogram. It is recommended that people who are exposed to loud noise regularly should be monitored with distortion product emission test. It is suggested that the use of walkman.
