Anti-nuclear antibody (ANA) negative systemic lupus erythematosus (SLE) occurs in about 4-13% of SLE cases. A small group of ANA negative SLE patients with positive anti-Ro antibodies usually present with typical vasculitic skin lesions which can be associated with photosensitivity, renal disease, congenital heart block or neonatal lupus. We present a case of a persistently ANA negative patient who presented with joint pain, rashes, mouth ulcer and alopecia. Clinical diagnosis of systemic lupus erythematosus was made even though ANA was negative. She was started on steroids and went into remission. Later, she developed several episodes of convulsions associated with fever and prominent vasculitic lesions. The patient was also found to have microscopic hematuria, proteinuria, anemia and thrombocytopenia. Renal biopsy showed lupus nephritis class 1B. Due to the prominent skin lesions, we performed anti-extractable nuclear antigens (ENA) antibodies test and anti-Ro turned out to be positive. The final diagnosis was ANA negative SLE (Ro lupus) with cutaneous, renal, musculoskeletal, hematological and cerebral Involvement.
This quantitative-oriented research was conducted to identify factors that contributed to errors in dispensing medication among nurses and to understand why nurses did not report their errors in dispensing. In this study a total of 284 U29 nurses participated in focusing on factors contributing to medication errors and failure to report the errors. In this study, analysis of the data collected was made in two sections; dispensing errors and failure to report the errors in giving medication. According to Evans et al. (2006) although nurses may not admit directly to such errors, they expressed their perceptions towards situations described in the questionnaire items as contributing to medication errors among nurses. Almost all in the sample of 284 chose not to report medication errors because they could not identify the cause of dispensing errors; other nurses perceived that the individual involved is not competent in performing the task. Other reasons include fear that the action will be exposed by the management, to avoid publicity from the media, and there is no difference in reporting or not reporting the medication errors. This study was done not only for exploring factors of medication errors; it also aspires to identify problems that arise in hospital services and in order to maintain the quality of health care. The management should consider the impact of medication errors and failure to report medication errors on the nursing profession and quality image of the hospital.
Thirty-eight cases of lupus nephritis, all satisfying the American Rheumatism Association criteria for diagnosis of systemic lupus erythematosus (SLE), with renal involvement and biopsy were immunohistochemically studied for the expression of HLA-DR (DAKO: HLA-DR/alpha, TAL.1B5), one of the three known families belonging to the class II major histocompatibility complex (MHC), using a standard streptavidin-biotin-peroxidase method. 20 nephrectomies performed for renal trauma and tumours constituted the normal controls. Of the lupus nephritis cases, 34 were females and 4 males. Ethnically, 20 were Chinese, 13 Malay, 4 Indian and 1 of indigenous origin. Their ages ranged from 16 to 59 years (mean of 31 years). Histologically, 23 expressed World Health Organisation (WHO) class IV (diffuse proliferative), 10 WHO class V (diffuse membranous), 4 WHO class II (pure mesangiopathy) and 1 WHO class III (segmental and focal proliferative) nephritis. Activity scores ranged between 5 to 19 (mean = 8.6) and chronicity scored between 2 to 7 (mean = 3.2) on a standard scoring system. Similar to other studies, HLA-DR was expressed in the glomerular capillaries and peritubular capillaries of all and mesangium, tubules (proximal, distal and collecting), veins and arterioles of some normal controls. Interestingly, HLA-DR expression was noted in the arteries of 25% of the normal controls, a finding hitherto not reported. The frequency of lupus nephritis cases expressing HLA-DR in the various anatomical components did not differ significantly from the normal controls except that HLA-DR expression in arteries and arterioles was seen at a significantly increased frequency (p < 0.01) in lupus nephritis. This increased expression did not correlate with the WHO class, activity or chronicity scores. It therefore appears that MHC class II shows increased expression in the arterial system of lupus nephritis kidneys. The significance of this is unclear but could be related to heightened (gamma-interferon activation which may be a de novo phenomenon or result of T cell proliferation and activation in SLE.
Formerly thought to have a constant incidence rate throughout the world, Wilms' tumour (nephroblastoma) has been shown to be less common among Asian children. A retrospective demographic and morphological study of Wilms' tumour histologically diagnosed over a 22-year period at the Department of Pathology, University Hospital, Kuala Lumpur was conducted to assess for inherent demographic and morphological differences between tumours in Malaysian children and those of Western populations. Thirty-seven cases of histologically proven Wilms' tumour qualified for inclusion in this study. 19 patients were Chinese, 13 Malay, 4 Indian and 1 Anglo-asian. 21 were male and 16 were female (M:F ratio = 1.3:1). Their ages ranged from 1 month to 4 years. 70.3% of the patients were below 2 years of age. 36 cases had unilateral and 1 bilateral tumours. Of unilateral tumours, 19 involved the left kidney and 17 the right. Histological assessment, based on criteria of the National Wilms' Tumor Study Group, revealed 20 (52.6%) tumours with a mixed pattern while 8 (21.1%) showed epithelial, 7 (18.4%) blastemal and 3 (7.8%) stromal-predominant patterns. Anaplasia was observed in only 2 tumours (5.3%). There was no obvious difference in age range and sex distribution, laterality of tumours and incidence of anaplasia between this and Western studies. No ethnic predilection was observed. A notably larger percentage of cases were below 2 years of age. Also, a larger proportion of epithelial-predominant and a lower proportion of blastemal-predominant tumours was observed compared with patterns reported from Western populations.
Over the last 8 years, 22 consecutive cases of subarachnoid haemorrhage were found to have no obvious cause on angiography. The age, neurological status and CT-scan appearance in 16 cases were studied together with the completeness and quality of the angiogram. Limited angiography was done in cases with advanced age, poor neurology or severe hypertension. There is a need for more repeat angiographic studies in the presence of vasospasm whether focal or generalised, as indicated by the fact that only 5 out of the 17 cases with vasospasm had repeated satisfactory studies.
OBJECTIVES: Atrial fibrillation (AF) is a well-recognised, major risk factor for ischaemic stroke. The presence of atrial fibrillation in a stroke patient translates into higher mortality rates and significant disability. There is lack of data on the impact of atrial fibrillation on stroke patients in Malaysia. The aim of this study was to determine the prevalence of AF in a hospital setting and determine the risk factors, clinical profile and discharge outcomes in ischaemic stroke patients with and without atrial fibrillation from a tertiary centre in Malaysia.
METHODS: This was a retrospective review of patients admitted consecutively to the University Malaya Medical Centre, Kuala Lumpur with the diagnosis of stroke during the first six months of 2009. The presence of AF was confirmed with a 12- lead ECG. All patients had neuroimaging with either cranial computed tomography (CT) or magnetic resonance imaging (MRI). Other variables such as clinical features, risk factors, stroke subtypes, length of acute ward stay, complications and evaluation at discharge (mortality) with modified Rankin scale (mRS) were also recorded.
RESULTS: A total of 207 patients were admitted with stroke during the study duration. Twenty two patients (10.6%) were found to have non valvular AF. Patients with AF were found to be older with a mean age of 71.0 ± 2.2 than those without AF with a mean age of 63.6 ± 0.89 (p<0.05). Risk factors for stroke such as diabetes mellitus and hypertension were equally common between the two groups while the proportion of patients with ischaemic heart disease was higher among patients with AF (p<0.005). Most of the stroke subtypes among patients with AF were of ischaemic type (n=192; 92.8%) while haemorrhagic stroke was uncommon (n=15; 6.2%). Patients with AF had a longer median hospital stay, higher mortality rate and greater functional disability on hospital discharge compared to non AF patients.
CONCLUSION: The prevalence of AF among stroke patients in a tertiary centre in Malaysia was 10.6%. Stroke patients with AF were observed to have a higher mortality rate and disability on hospital discharge.

BACKGROUND: Myofascial pain syndrome (MPS) is a regional musculoskeletal pain disorder that is caused by myofascial trigger points. The objective of this study was to determine the prevalence of MPS among chronic back pain patients, as well as to identify risk factors and the outcome of this disorder.
METHODS: This was a prospective observational study involving 126 patients who attended the Pain Management Unit for chronic back pain between 1st January 2009 and 31st December 2009. Data examined included demographic features of patients, duration of back pain, muscle(s) involved, primary diagnosis, treatment modality and response to treatment.
RESULTS: The prevalence of MPS among chronic back pain patients was 63.5% (n = 80). Secondary MPS was more common than primary MPS, making up 81.3% of the total MPS. There was an association between female gender and risk of developing MPS (χ(2) = 5.38, P = 0.02, O.R. = 2.4). Occupation, body mass index and duration of back pain were not significantly associated with MPS occurrence. Repeated measures analysis showed significant changes (P < 0.001) in Visual Analogue Score (VAS) and Modified Oswestry Disability Score (MODS) with standard management during three consecutive visits at six-month intervals.
CONCLUSIONS: MPS prevalence among chronic back pain patients was significantly high, with female gender being a significant risk factor. With proper diagnosis and expert management, MPS has a favourable outcome.

The relationship between the timing of maternal tetanus toxoid immunization and the presence of protective antitoxin in placental cord blood was investigated among women admitted to the obstetrical service of the University Hospital in Kuala Lumpur, Malaysia. The 1st dose was given between 13-39 weeks of gestation, with a median of 29 weeks. The 2nd dose was given an average of 4 weeks later. Protection was conferred on 80% or more of newborns whose mothers received their 1st tetanus toxoid injection 60 days or more before delivery. Protective levels were seen in all cord blood samples from infants whose mothers had received their 1st injection 90 days before delivery. Similarly,protective titers were found in 100% of cord blood samples when the 2nd maternal injection was give 60 days or more before delivery. There was no significant degree of protection when immunization was carried out less than 20 days before delivery. A single-dose schedule provided no protection when less than 70 days before delivery. Cord and maternal antiotoxin titers differed by no more than 1 2-fold dilution for almost all of the individual paired sera. A cord: maternal antitoxin ratio of 2 was more likely to occur with increasing time between the 2nd injection and delivery. Overall, these findings indicate that the 1st injection of a 2-dose maternal tetanus toxoid schedule should be given at least 60 days and preferably 90 days before delivery.
Over the past hundred years in industrialised countries and recently in some developing countries, children have been getting larger and growing to maturity more rapidly. This paper compares the growth of Malaysian children with similar socioeconomic backgrounds but born about twelve years apart. Data were obtained from records of 227 children born between 1968 and 1973 and 238 children born between 1980 and 1985. The children were followed-up regularly at the University Hospital Child Health Clinic in Kuala Lumpur for a variable period from birth to five years of age. Measurements for their weight, length and head circumference were taken at each visit. There is a directional indication that boys and girls of the 1980-1985 cohort are taller, heavier and have bigger head circumferences from birth to five years of age and the difference widens as the child grows older. This study clearly shows that a positive secular trend has taken place in the last decade, reflecting an improvement of living conditions with time. The factors involved in the positive secular trend are manifold and the most important is probably nutrition.
This case illustrates an 80-year-old lady who presented with acute low back pain and finally succumbed from complications of osteoporotic vertebral fracture. Among the contributing factors are delayed diagnosis and a lack of continuity of care. It reminds the practitioners of the importance to look out for red flag symptoms and to have a high index of suspicion for vertebral fracture in high risk patients presenting with low back pain.

A total of 45 patients with IgA nephropathy were seen at the Department of Nephrology, General Hospital, Kuala Lumpur and the Department of Medicine, Universiti Kebangsaan Malaysia (National University ofMalaysia) between January 1982 to June 1985. This represents an incidence of 10.7% of all primary glomerulopathies. There does not appear to be any racial predilection and the clinicopathological features generally conforms with those reported elsewhere. However it seems to be as common in females as in males but the latter have a worse prognosis. The high incidence of renal failure and hypertension in our patients within the short follow-up period is noteworthy.
Two-hundred and sixty-five patients with asymptomatic proteinuria and/or haematuria were studied at the Department of Medicine, Universiti Kebangsaan Malaysia and Department of Nephrology, General Hospital Kuala Lumpur. They represented 25.4% of all the renal biopsies performed during the period 1980-88. All the three races were affected with 71.3% occurring between the ages of 20-39 years and 41.1% were detected during routine medical examination. Excluding those patients with lupus nephritis, IgA nephropathy was the commonest histological diagnosis (51.7%). The presence of severe and advanced histological changes in a significant number of biopsies emphasises the need for more effective screening and early referral of this group of patients.
Systemic lupus erythematosus (SLE) is an autoimmune disease characterised by increased B cell activity and depressed T cell function. However, the contribution of the immunoregulatory system to its pathogenesis is still unclear. The recent development in the production of monoclonal antibodies and the availability of bench-top flow cytometers have allowed rapid quantitation of peripheral blood lymphocyte subsets. We analysed the distribution of the lymphocyte subsets in 24 patients with active SLE and 18 with inactive SLE. The distribution of immunoregulatory cells in 72 normal volunteers was used as control. Statistical analysis showed that there were significant differences between both the SLE groups and the normal controls, for total lymphocytes, T cells, B cells, T helper cells, T suppressor cells, T helper/suppressor ratio and natural killer cells. There was a significant difference for T helper cells between active and inactive SLE. T helper cells levels were found to be low in inactive SLE and lower in active SLE. It appears that treatment-induced remissions did not restore the levels of immunoregulatory cells to normal. Thus, T helper cell levels reflect disease activity and longitudinal assays of T helper cells may serve as an indicator of disease reactivation.
INTRODUCTION: The purpose of this study is to examine the prevalence of social support and its association with glycemic control in patients with type 2 diabetes mellitus (T2D) in an urban primary care center within an academic institution. Social support is important in the management of chronic diseases. However, its association with glycemic control has been controversial.
METHODS: This was part of a study examining religiosity in T2D patients. Nonsmoking patients with T2D for at least 3 years and aged 30 years and above were recruited. Social support was measured using The Social Support Survey-Medical Outcomes Study (SS), a self-administered questionnaire; the scores range from 19 to 95, and a high score indicates better social support. Glycemic control was measured using the 3 most recent glycosylated hemoglobin (HbA1c) levels within the past 3 years.
RESULTS: A total of 175 participants completed the SS survey (response rate 79.0%). The mean age was 62.7 (standard deviation [SD] = 10.8) years, and the mean duration of diabetes was 11.74 (SD = 6.7) years. The mean HbA1c level was 8.15 (SD = 1.44). The mean SS score was 68.1. The prevalence of high and low social support were 29.7% and 24.0 %, respectively. A significant correlation was found between SS score and number of social supporters (n = 167). No significant correlation was found between the self-reported number of social supporters or the SS score and the mean HbA1c level.
CONCLUSIONS: Social support was not associated with glycemic control in adult patients with T2D in this primary care setting.

Background To determine the relationships between religiosity, religions and glycaemic control of type 2 diabetes mellitus (T2D).Methods This is a cross-sectional study conducted at an urban, university-based, teaching outpatient clinic. Religiosity was assessed with the Beliefs and Values Scale (BV), which contains 20 items each with a Likert scale of five possible responses. The range of scores is 0 to 80, with a higher score indicating stronger religious belief. Glycaemic control was taken as the mean value of the latest three fasting plasma glucose (FPG) levels and HbA1c readings documented in each patient's case records.Results A total of 212 patients participated (a response rate of 79%). Two-thirds were female, mean age was 62.7 (SD 10.8) years and mean duration of T2D was 11.7 (SD 6.7) years. The mean BV score was 57.4 (SD 10.97, CI 55.9, 59.0). Religiosity had a negative correlation with lower FPG (r = -0.15, p = 0.041) but no such correlation was found with HbA1c. Moslem religiosity had a significant negative correlation with HbA1c (r = -0.34, p = 0.007, n = 61) even after controlling for covariates. Christians and non-religious group had significantly lower mean rank HbA1c than other religions (p = 0.042).Conclusions Those with higher religiosity amongst the Moslem population had significantly better glycaemic control. Patients who had church-going religions had better glycaemic control compared with those of other religions.

BACKGROUND: hip fractures are an increasing source of morbidity and mortality in older people. The role of visual function tests such as visual impairment, stereopsis, contrast sensitivity and visual field defects in low fragility hip fractures in Asian populations is not well understood.
OBJECTIVE: to determine the association between various visual function tests and low fragility hip fractures in an Asian population.
DESIGN: case-control study.
SETTING: University Malaya Medical Centre, Kuala Lumpur, Malaysia.
SUBJECTS: 108 cases aged > or = 55 years admitted with low fragility fractures and 108 controls (matched for age, gender and race).
METHODS: both cases and controls underwent a detailed ophthalmological examination, which included visual acuity, stereopsis, contrast sensitivity and visual field testing.
RESULTS: poorer visual acuity (odds ratio, OR = 4.08; 95% confidence interval, CI: 1.44, 11.51), stereopsis (OR = 3.60, 95% CI: 1.55, 8.38), contrast sensitivity (OR = 3.34, 95% CI: 1.48, 7.57) and visual field defects (OR = 11.60, 95% CI: 5.21, 25.81) increased the risk of fracture. Increased falls were associated with poorer visual acuity (OR = 2.30, 95% CI: 1.04, 5.13), stereopsis (OR = 2.11, 95% CI: 1.03, 4.32), contrast sensitivity (OR = 2.12, 95% CI: 1.05, 4.30) and visual field defects (OR = 3.40, 95% CI: 1.69, 6.86).
CONCLUSION: impaired visual acuity, stereopsis, contrast sensitivity and visual field defects are associated with an increased risk of low fragility hip fractures. We recommend that all patients aged > or = 55 should have an annual ophthalmological examination that includes visual acuity, contrast sensitivity, stereopsis and visual field testing to assess the risks for falls and low fragility fractures.
BACKGROUND: Good coronary care begins from the patient's home, including early transportation. As such, it is recommended that the patients activate ambulances, rather than to use their own transportations to reach the hospitals. It is not known whether Malaysian patients prefer to use private transportations or ambulances when they develop chest pain.
OBJECTIVES: This study is conducted to explore the question of the choice of transportation modes among patients with acute coronary syndrome and the reasons behind their choices.
METHODS: This is a structured interview survey on patients diagnosed with acute coronary syndrome (ACS) in emergency department of Hospital Universiti Sains Malaysia from April 2012 to September 2012.
RESULTS: Out of the 110 patients surveyed, 105 (95.5%) patients chose to use own transportation when they developed symptoms suggestive of ACS. Only 3 patients (2.7%) came to the emergency department within 1 hour of onset, and all these 3 patients chose to use ambulances as their modes of transportation. None of the patients who chose own transportation came within the first hour of symptoms onset. This is shown to be statistically significant (p<0.001). The level of education as well as past history of ischemic heart disease did not significantly influence the patients' choice of transportation.
CONCLUSION: The admonishment by various international resuscitation councils that patients with chest pain should be transported via ambulances may not be as straightforward as it seems. Numerous local and regional socio-cultural and logistic factors may need to be addressed.
INTRODUCTION: Aimed at providing integrated multi-level crisis intervention to women experiencing violence such as rape, One Stop Crisis Centre (OSCC) in Malaysia is often located in the emergency department. Hence, it is imperative that emergency department healthcare providers possess adequate knowledge and acceptable attitudes and practices to ensure the smooth running of an efficient OSCC work process.
METHOD: To study the knowledge, attitude and practice of rape management in OSCC among four groups of healthcare providers in the emergency department [i.e., the emergency medicine doctors (EDs), the staff nurses (SNs), the medical assistants (MAs) and the hospital attendants (HAs)], a selfadministered questionnaire in the form of Likert scale was conducted from January to October 2013. Correct or favourable responses were scored appropriately.
RESULTS: Out of the 159 participants invited, 110 responded (69.2% response rate). As all data sets in the Knowledge, Attitude and Practice sections are non-parametric, Kruskal- Wallis test was performed. Homogeneity of variance was verified using non-parametric Levene test. In all three sections, there are statistically significant differences in scores obtained among the four groups of healthcare providers with H(3) = 16.0, p<0.001 for Knowledge, H(3) = 27.1, p<0.001 for Attitude and H(3) = 15.8, p<0.001 for Practice sections. Generally, the SNs obtained the highest mean rank score in the knowledge and practice sections but the EDs obtained the highest mean rank score in the attitude section. Some of the responses implied that our healthcare providers have the victim-blaming tendency that can negatively impact the victims.
CONCLUSION: Healthcare providers must not only have adequate knowledge but also the non-judgemental attitude towards victims in OSCC.
INTRODUCTION: Bystander cardiopulmonary resuscitation (CPR) serves as a vital link to improve the chance of survival among the out-of-hospital cardiac arrest (OHA) patients. The frequency of bystander CPR in Malaysia is largely unknown. The aim of this study was to find out how frequently bystander CPR was performed among OHA patients with CPR performed at the Emergency Department (ED), Hospital Universiti Sains Malaysia (HUSM), prior to their arrival to the department.
METHODS: In this one-year observational study, data was collected from cases of CPR performed in ED, HUSM. In the OHA category, a subanalysis was further performed to look into the frequency and effects of bystander CPR on achieving return of spontaneous circulation and survival to hospital admission. The categorical data collected was analysed using chi-square test or Fisher-exact test.
RESULTS: Out of a total of 23 OHA patients that had CPR performed on arrival at the ED, HUSM, from March 2005 to March 2006, only two cases (8.7 percent) had bystander CPR performed. None of these two cases achieved return of spontaneous circulation.
CONCLUSION: Although this study has many limitations, it does indicate that the frequency of bystander CPR is dismally low in our community and the mere fact that bystander CPR was reported to be done does not seem to translate into a higher chance of survival to admission. The quality and effectiveness of the technique is equally important.
