We conducted a prospective study in order to audit our experience of repairing cranial defects using Methyl methacrylate. This included a total of 49 patients undergoing cranioplasty using methyl methacrylate, of which 45 were males and 4 females. The age of patients at the time of surgery ranged from 16 to 40 years old, with an average of 24 years. Malays were the majority (67%), followed by Chinese (23%) and Indian (10%). Cranial defects were mainly caused by motor vehicle accident (94%), while gunshot wounds, industrial accidents and tumours, each contribute 2%. Bone flaps were commonly removed during previous surgery related to traumatic subdural haemorrhage (33%), contusion (21%) and intracerebral haemorrhage (14%). The size of cranial defects ranged from 28 cm2 to 440 cm2, with an average of 201 cm2. Most had right sided (55%) and lateral defects [temporoparietal (52%) followed by temporal (16%), frontal (16%), frontotemporal (14%) and occipital (2%)]. Duration of surgery ranged from 70 to 275 minutes, with an average of 135 minutes. Nine of 12 patients (75%) with neurological disability had some improvement while 85% of symptomatic patients had symptoms improvement after cranioplasty. The infection rate in this series was 4%.
A cross-sectional study was conducted to determine the risk factors of job-related depression in laboratory technicians in Hospital Universiti Sains Malaysia (HUSM) and Kementerian Kesihatan Malaysia (KKM) Hospitals in Kelantan, between September 2001 and February 2002. One hundred and two laboratory technicians from HUSM and 79 from KKM Hospitals were selected and 84 (82.4%) from HUSM and 71 (89.9%) from KKM Hospitals were recruited as study subjects. Data were collected by self-administered questionnaire using the validated Malay version of the Job Content Questionnaire (JCQ), originally developed by Robert Karasek. The results indicated significant associations between the risk factors of job-related depression, and low social support, and high psychological demands (OR 3.0, 95% CI 1.1-8.8) in laboratory technicians in HUSM. However, for laboratory technicians in KKM Hospitals, the significant association was between job-related depression, and low social support and low decision authority (OR 9.7, 95% CI 1.1-91.1). Low social support was highly associated with job-related depression in laboratory technicians in HUSM and KKM Hospitals. We, therefore, conclude that low social support positively predicted depression in laboratory technicians in HUSM and KKM Hospitals. In addition, high psychological demands also significantly predicted depression in laboratory technicians in HUSM; however, for laboratory technicians in KKM Hospitals, low decision authority was the significant predictor of depression.
Minor head injury in a developing country like Malaysia is managed by primary care physicians and/or medical assistants in district hospitals. These patients are seen initially in their local hospitals, which have at least an X-ray machine for the purpose of screening. This study aimed to guide these physicians to manage these patients at a primary care level. A cross-sectional study was conducted and the study revealed significant predictors of significant computed tomographic (CT) findings. The presence of a Glasgow coma scale (GCS) score of 14 or 13 was associated with the risk of developing significant CT findings compared to patients with a GCS of 15 (p<0.001). Thirty-seven out of 50 patients with GCS of 14 or 13 developed clinically significant brain injury on CT scan. Similarly, the presence of skull fracture was associated with the risk of developing CT abnormalities (p<0.001). Forty-two out of 51 patients with skull fracture developed clinically significant CT findings. Vomiting was associated with developing CT abnormalities (p=0.017). Twenty-seven out of 40 patients with vomiting showed significant CT findings. Soft tissue injury was also found to be associated with developing CT abnormalities (p=0.007). Therefore, we propose reclassifying minor head injury based on the GCS score. Patients with a GCS score of 15 were classified as having mild head injury, while patients with a GCS score of 13 or 14 were at higher risk of developing brain injury and therefore categorized as high risk mild head injury. This group requires emergency CT scan examination, especially when associated with non-motor vehicle accidents, abnormal central nervous system (CNS) examination, craniofacial injuries or skull fractures. They should be referred to a general surgical unit which can treat head injuries or a neurosurgical tertiary centre.
BACKGROUND: Improving health-related quality of life (HRQoL) among people with epilepsy (PWE) has become the focus of various treatment programmes and behavioural interventions which continue to be challenging to both patients and healthcare professionals.
AIMS AND OBJECTIVES: To investigate the impact of SMS-based epilepsy education programme on PWE's HRQoL status and to determine the predictors for good HRQoL.
METHODS: Eligible epilepsy out-patients from three public hospitals in East Coast Peninsular Malaysia were randomized into two groups: intervention (IG) and control (CG). Patients in the CG were supplied with only printed epilepsy educational module, while those in the IG additionally received short message service (SMS) from the Mobile Epilepsy Educational System (MEES). The Malay Quality of Life in Epilepsy Inventory-30 (MQOLIE-30) was utilized for HRQoL assessment. Descriptive statistics, paired t test, analysis of covariance and multiple logistic regression were employed for data analyses (SPSS 16).
RESULTS: One hundred and forty-four PWE were recruited for the study (age = 30.5 ± 11.8; unmarried = 60.4 %; education level ≤ SPM/Cambridge O' level = 76.4 %; illness duration > 5 years = 51.1 %). After controlling for possible confounders, IG exhibited positive changes in HRQoL profile compared to CG particularly in Seizure Worry, Overall Quality of Life, Emotional Well-Being, Social Functioning and Overall Score (p < 0.05). After adjusting for covariates, being employed and receiving additional SMS-based epilepsy education programme emerged as the significant predictors of good HRQoL among PWE.
CONCLUSION: Receiving continuous SMS-based epilepsy information from the MEES seemed to generate positive impacts on PWE's overall HRQoL. This study has provided a basis for future innovations to inspire efforts in ensuring the welfare and HRQoL of PWE and their families.

Imbalance between antioxidant and oxidative stress is a major risk factor for pathogenesis of some chronic diseases such as chronic obstructive pulmonary disease (COPD). This study aimed to determine antioxidant and oxidative stress status, and also theirs association with respiratory function of male COPD patients to find the antioxidant predictors' factors. A total of 149 subjects were involved in a cross-sectional study. The study was conducted at two medical centers in Kuala Lumpur, Malaysia. Results of the study showed that plasma vitamin C was low in most of the subjects (86.6%). Total antioxidant capacity was the lowest in COPD stage IV compare to other stages (p < 0.05). Level of plasma vitamin A (p= 0.012) and vitamin C (p= 0.007) were low in malnourished subjects. The predictors for total antioxidant capacity were forced vital capacity (FVC) % predicted and intake of ?-carotene (R2= 0.104, p= 0.002). Number of cigarette (pack/ year) and smoking index (number/ year) were not associated with total antioxidant capacity of this COPD population. Plasma oxidative stress as assessed plasma lipid peroxidation (LPO) was only positively correlated with plasma glutathione (p= 0.002). It might be a need to evaluate antioxidant status especially in older COPD patients to treat antioxidant deficiency which is leading to prevent COPD progression.

BACKGROUND: Methotrexate (MTX) is a common and efficacious systemic agent used for the treatment of moderate to severe psoriasis. Nevertheless, its use is associated with the risk of hepatotoxicity. This study was performed to study the association of MTX dose with regards to hepatotoxicity as evidenced by deranged transaminases.
METHODS: This was a retrospective review of patients with psoriasis on MTX from 2000 to 2009 at the outpatient dermatology clinic, University Malaya Medical Centre (UMMC). We analyzed patients' demography, serial laboratory investigations, liver ultrasounds, and liver biopsies of patients on MTX.
RESULTS: Sixty-six of 710 (9.30%) patients with psoriasis were prescribed MTX throughout the 10-year period. Among them 57.6% developed deranged transaminases, with six requiring MTX withdrawal due to hepatotoxicity. The mean cumulative dose of MTX at the detection of liver enzyme derangement was 552.3 ± 596.1 mg.
CONCLUSION: A high proportion of patients on MTX had deranged transaminases. However, the number of serious events was low. We concluded from this study that the use of MTX is relatively safe in patients with moderate to severe psoriasis.

This is a case report of an extremely rare condition of atlanto-axial subluxation secondary to gouty arthritis, which mimicked rheumatoid arthritis at presentation. Gouty arthritis involving the spine is a rare condition. We highlight a case of gouty arthritis involving the atlanto-axial joint resulting in joint instability, subluxation, and neurological deficit. A 66-year-old obese woman who had a polyarticular disease for the previous 3 years presented with neck pain and progressive neurology. A 2-stage procedure was performed: posterior decompression and occipitocervical fusion followed by further anterior trans-oral decompression. However, after an initial neurological improvement, she succumbed to aspirational pneumonia and septicaemia. Atlanto-axial subluxation caused by gouty arthritis can present in the same way as rheumatoid arthritis. Therefore, the possibility of this as a differential diagnosis should be kept in mind.
This study was conducted to determine the tolerability and efficacy of valsartan (DIOVAN) compared to perindopril (COVERSYL) in Malaysian patients with mild to moderate hypertension. Two hundred and fifty adult Malaysian patients with a mean sitting diastolic blood pressure of more than 95 mmHg and less than 115 mmHg after a 14 day washout period were randomized to receive either valsartan 80 mg once daily (n=125) or perindopril 4 mg daily (n=125) for eight weeks. The primary end point for efficacy was the change in mean sitting systolic and diastolic blood pressure (SiSBP and SiDBP). The primary criteria for evaluation of tolerability was the incidence of adverse events. There were no significant differences between the two groups with respect to sex, age, weight, baseline sitting and standing systolic and diastolic blood pressure. At 0, 4 and 8 weeks the mean SiDBP in the valsartan group were 101.4, 92.8 and 91.0 mmHg respectively. The corresponding BP for the perindopril treated group was 102.6, 93.8 and 93.2 mmHg. (95% CI -1.39 to +3.27). There were no significant differences in the mean BP measurements between the valsartan and perindopril group at 0, 4 and 8 weeks. In each group there were significant differences between the BP at 4 and 8 weeks compared to baseline. A similar pattern was seen with SiSBP. At 4 weeks 28.7% of the valsartan and 25% of the perindopril group had their BP normalized (SiDBP <90 mmHg) The percentages of patients who responded (SiDBP reduction >10 mmHg but SiDBP >90 mmHg) were 21.3 in the valsartan group and 20.8 in the perindopril group. At 8 weeks, 31.1% of the valsartan group and 30.8% of the perindopril group had their BP normalized. The response rate was 27% and 22.5% for valsartan and perindopril respectively. The major adverse event was cough which occurred in 18 patients (14.4%) in the perindopril and 1 (0.8%) in the valsartan group at 4 weeks. At 8 weeks the figures were 24 (19.2%) and 2 (1.6%) respectively. The results indicate that Valsartan is safe and efficacious in the treatment of mild to moderate hypertension. It is equally efficacious to Perindopril and not associated with any major adverse event. It has a better tolerability profile with respect to dry cough.
The objective of this study was to assess the efficacy and safety of oral 30% dextrose during venepuncture in neonates. Neonates admitted in the Special Care Nursery for jaundice from September 200 to January 2001 were recruited for this double-blind randomised controlled trial. The intervention consisted of administration of either 2 ml of oral 30% dextrose or 2 ml of sterile water 2 minutes before venepuncture. The primary outcome measure was the cumulative Neonatal Infant Pain Scale (NIPS) score at 3 minutes after venepuncture and the duration of cry assessed from a videotaped recording. Twenty-six neonates received 30% dextrose and 26 neonates received sterile water. The cumulative NIPS score at 3 minutes (median, IQR) after venepuncture for neonates given 30% dextrose (13, 6.8-21) was significantly (p = 0.03) lower than that for neonates given sterile water (21, 13.8-21). The duration of cry in neonates given 30% dextrose (median 45 sec IQR 1.5-180.8 sec) was significantly (p = 0.03) shorter than that in neonates given sterile water (median 191 sec IQR 52.3-250 sec). No neonates developed diarrhoea, fever or rash during the 24 hour observation period. Both the intra-rater (ICC 0.993 95% CI 0.988-0.996) and inter rater (ICC 0.988 95% CI 0.980-0.993) agreement on the 3-minute NIPS score were good. In conclusion oral 30% dextrose given 2 minutes before venepuncture was effective in reducing neonatal pain following venepuncture. It is a simple, safe and fast acting analgesic and should be considered for minor invasive procedure in term neonates.
beta-Lactamases have been identified as the major cause of antimicrobial resistance to beta-lactam antibiotics in Escherichia coli. The activities of ampicillin-sulbactam and amoxicillin-clavulanate as well as a range of beta-lactam antibiotics were studied with 87 clinical E. coli isolates from patients of the University Malaya Medical Center using the disc diffusion technique. Susceptible, intermediate and resistant categories were established based on the diameter of zones of inhibition set by the National Committee for Clinical Laboratory Standards (NCCLS). The isolates were then classified into 6 phenotypes according to the criteria stated in the methodology: S (susceptible to all beta-lactams); TL (resistant to aminopenicillins; amoxicillin-clavulanate susceptible and susceptible or intermediate to ampicillin-sulbactam); TI (resistant to aminopenicillins and ampicillin-sulbactam; susceptible to amoxicilin-clavulanate); TH-IRT (resistant to aminopenicillins; intermediate or resistant to amoxicillin-clavulanate; resistant to ampicillin-sulbactam); ESBL (resistant to aminopenicillins and oxyimino cephalosporins; positive results with the double-disc diffusion test); and CP (resistant to aminopenicillins, beta-lactam-beta-lactamase inhibitor combinations, oxyimino cephalosporins and cephamycins). Results showed that the TL phenotype was the commonest (40.2% of the isolates) followed by S (31%), TH-IRT (16.1%), ESBL and CP (3.4% each) and TI (2.3%). One isolate showed both ESBL and CP phenotypes while two isolates were classified as inconclusive. Representatives from each phenotype were further analysed for the presence of beta-lactamases which revealed a predominance of TEM and SHV enzyme producers. PCR-SSCP analysis of the SHV gene from all the ESBL and CP isolates revealed the predominance of SHV 5-type enzyme which was concurrent with our previous studies.
Osteoarthritis (OA) exacerbates skeletal muscle functioning, leading to postural instability and increased falls risk. However, the link between impaired physical function, OA and falls have not been elucidated. We investigated the role of impaired physical function as a potential mediator in the association between OA and falls. This study included 389 participants [229 fallers (≥2 falls or one injurious fall in the past 12 months), 160 non-fallers (no history of falls)], age (≥65 years) from a randomized controlled trial, the Malaysian Falls Assessment and Intervention Trial (MyFAIT). Physical function was assessed using Timed Up and Go (TUG) and Functional Reach (FR) tests. Knee and hip OA were diagnosed using three methods: Clinical, Radiological and Self-report. OA symptom severity was assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC). The total WOMAC score was categorized to asymptomatic, mild, moderate and severe symptoms. Individuals with radiological OA and 'mild' overall symptoms on the WOMAC score had reduced risk of falls compared to asymptomatic OA [OR: 0.402(0.172-0.940), p = 0.042]. Individuals with clinical OA and 'severe' overall symptoms had increased risk of falls compared to those with 'mild' OA [OR: 4.487(1.883-10.693), p = 0.005]. In individuals with radiological OA, mild symptoms appear protective of falls while those with clinical OA and severe symptoms have increased falls risk compared to those with mild symptoms. Both relationships between OA and falls were not mediated by physical limitations. Larger prospective studies are needed for further evaluation.

Pseudo-pseudo Meigs' syndrome (PPMS) has been reported to be a rare presentation of patients with systemic lupus erythematosus (SLE). However, such a presentation is not common in other forms of connective tissue disease. We presented a case of gross ascites, pleural effusion, and marked elevation of CA-125 level (PPMS-like features) that led to a diagnosis of MCTD. The patient responded to systemic steroid therapy.
OBJECTIVE: This study aims to identify Comprehensive Geriatric Assessment (CGA) based risk factors to help predict caregiver burden among elderly patients with cancer.
MATERIALS AND METHOD: The study evaluated 249 patients newly diagnosed with cancer, aged 70years and above, who attended the geriatric oncology clinic at the National Cancer Centre Singapore between 2007 and 2010.
RESULTS: Out of 249 patients, 244 patients had information available on family caregiver burden and were analysed. On univariate analysis, ADL dependence, lower IADL scores, ECOG performance status of 3-4, higher fall risk, lower scores in dominant hand grip strength test and mini mental state examination, polypharmacy, higher nutritional risk, haemoglobin <12g/dL and presence of geriatric syndromes were significantly associated with mild to severe caregiver burden. On multivariate analysis, only ECOG performance status of 3-4 (odds ratio [OR], 4.47; 95% confidence interval [CI], 2.27-8.80) and haemoglobin <12g/dL (OR, 2.38; 95% CI, 1.14-4.99) were associated with an increased probability of mild to severe caregiver burden. The model achieved a good fit (Hosmer-Lemeshow's p=0.196) and discrimination (area under the curve [AUC]=0.742; bias-corrected AUC=0.737). Based on this, patients were stratified into 3 risk groups with different proportion of patients with increased caregiver burden (low risk: 3.9% vs intermediate risk: 18.8% vs high risk: 39.6%; p<0.001).
CONCLUSION: ECOG performance status and haemoglobin were associated with increased caregiver burden among elderly patients with cancer. Using these two factors in the clinic may help clinicians identify caregivers at risk and take preventive action to mitigate that.
PURPOSE: To examine correlates of disability in Asian patients with major depressive disorder (MDD).
DESIGN AND METHODS: Participants were outpatients with DSM-IV MDD. Global disability and three disability domains (i.e., work/school, social life/leisure, and family/home life) were key outcomes. Several socio-demographic and clinical characteristics were determined for their associations with disability.
FINDINGS: The sample was 493 MDD patients. Apart from the number of hospitalizations, the global disability was significantly associated with depression severity, fatigue, physical health, and mental health. Several clinical but only few socio-demographic characteristics associated with the other three disability domains were similar.
PRACTICE IMPLICATIONS: Disability among Asian patients with MDD correlates with the severity of psychiatric symptoms and the hospitalizations due to depression. Socio-demographic characteristics have little impact on the overall disability.

OBJECTIVE: This study aims to examine the validity of the Framingham general cardiovascular disease (CVD) risk chart in a primary care setting.
DESIGN: This is a 10-year retrospective cohort study.
SETTING: A primary care clinic in a teaching hospital in Malaysia.
PARTICIPANTS: 967 patients' records were randomly selected from patients who were attending follow-up in the clinic.
MAIN OUTCOME MEASURES: Baseline demographic data, history of diabetes and smoking, blood pressure (BP), and serum lipids were captured from patient records in 1998. Each patient's Framingham CVD score was computed from these parameters. All atherosclerotic CVD events occurring between 1998 and 2007 were counted.
RESULTS: In 1998, mean age was 57 years with 33.8% men, 6.1% smokers, 43.3% diabetics and 59.7% hypertensive. Median BP was 140/80 mm Hg and total cholesterol 6.0 mmol/L (1.3). The predicted median Framingham general CVD risk score for the study population was 21.5% (IQR 1.2-30.0) while the actual CVD events that occurred in the 10 years was 13.1% (127/967). The median CVD points for men was 30.0, giving them a CVD risk of more than 30%; for women it is 18.5, a CVD risk of 21.5%. Our study found that the Framingham general CVD risk score to have moderate discrimination with an area under the receiver operating characteristic curve (AUC) of 0.63 [c-statistic or c-index]. It also discriminates well for Malay (AUC 0.65, p=0.01), Chinese (AUC 0.60, p=0.03), and Indians (AUC 0.65, p=0.001). There was good calibration with Hosmer-Lemeshow test χ(2)=3.25, p=0.78.
CONCLUSIONS: Taking into account that this cohort of patients were already on treatment, the Framingham General CVD Risk Prediction Score predicts fairly accurately for men and overestimates somewhat for women. In the absence of local risk prediction charts, the Framingham general CVD risk prediction chart is a reasonable alternative for use in a multiethnic group in a primary care setting.

OBJECTIVES: To investigate association between quality of life (QoL) and International Normalized Ratio (INR) control, with the secondary aim of assessing QoL using generic and anticoagulation-specific, the Short Form Health Survey (SF-12) and the Duke Anticoagulation Satisfaction Scale (DASS).
STUDY DESIGN: This study assessed anticoagulation related QoL at three time intervals in two groups of patients on long-term warfarin therapy.
METHODS: Data of 326 randomly sampled patients (163 patients each in DASS and SF-12 groups) who had been on warfarin therapy for at least one year at anticoagulation clinics were analysed. QoL was assessed at three time intervals: at the start, six months and one year of warfarin therapy. Indications and target INR ranges and subjects INR values were recorded. Time in Therapeutic Range (TTR) was estimated for four subject subgroups, based on target ranges of INR for clustered indications.
RESULTS: Of the total, 43% of the subjects were aged between 50 and 64 years, and 51% were female. DASS assessed subjects older than 35 years perceived significant decrease in overall mean scores of anticoagulation related QoL, whilst all SF-12 assessed subjects perceived an increase in QoL. The mean percentage days in range for all INR target range subgroups did not exceed more than 60% but there was only a weak correlation (Rs = 0.104, P > 0.05) between INR control and overall QoL.
CONCLUSION: Malaysian urban outpatients on warfarin treatment longer than one year report a significant overall decrease in QoL, as measured using a validated condition-specific instrument. These patients appeared to adapt well to lifestyle limitations imposed by long-term anticoagulation.

According to WHO, Malaysia has been classified as a concentrated epidemic country due to progression of HIV infection in the population of injecting drug users. The main objectives of current study are to determine the prevalence of HBV among HIV-positive individuals in a tertiary care hospital of Malaysia and to assess the predictors involved in the outcomes of HIV-HBV co-infected patients. A retrospective, cross-sectional study is conducted at Hospital Palau Pinang, Malaysia. The collection of socio-demographic data as well as clinical data is done with the help of data collection form. Data were analyzed after putting the collected values of required data by using statistical software SPSS version 20.0 and P > 0.05 is considered as significant. Results show that the overall prevalence of HBV was 86 (13%) including 495 (74.5%) males and 169 (25.5%) females among a total of 664 HIV-infected patients. It was observed that there is a high prevalence of HIV-HBV co-infection in males 76 (11.4%) as compared to females 10 (1.5%) (P = 0.002). The median age of the study population was 39 years. The statistical significant risk factors involved in the outcomes of HIV-HBV co-infected patients were observed in the variables of gender, age groups, and injecting drug users. The findings of the present study shows that the prevalence of HBV infection among HIV-positive patients was 13% and the risk factors involved in the outcomes of HIV-HBV co-infected patients were gender, age, and intravenous drug users.
This study aimed to evaluate dry powder inhaler naive asthmatic patients' perception and preference of the Accuhaler, a multidose dry powder inhaler and the pressurized metered dose inhaler (pMDI). After the first instruction, 66.7% of 48 patients enrolled in the study could demonstrate the correct use of the Accuhaler. When the patients were asked to compare the pMDI and the Accuhaler after using the Accuhaler to administer salmeterol for 4 weeks, the Accuhaler scored significantly better than the pMDI for the following features: knowing how many doses are left, presence of an attached cover, taste, instruction for use, attractiveness, ease of use, ease of holding, shape, and comfortable mouthpiece. The pMDI scored better to the Accuhaler in terms of size. More patients preferred the Accuhaler than the pMDI; the presence of a dose counter and perceived ease of use were the main reasons cited for their preference for the Accuhaler.

Out of 218 fractures of humeral shaft treated in the department, 23 (10.5%) of them developed non-union. 14/23 (60.9%) fracture were located in middle third. Transverse (52.2%), short oblique (17.4%) and comminuted fracture (13.0%) constituted about 82% of all initial fracture pattern. Twelve cases (52.5%) were initially treated with hanging cast. Radial nerve palsy occurred in 4/23 (17.4%) of patient and all of them located at lower third of humerus and only one recovered after eight weeks of injury. Factors such as middle third comminuted opened fractures, soft tissue interposition, improper immobilization and poor patient compliance were found to be directly associated with the non-union. All non-unions healed following plating and bone grafting. Overall 17/23 patient (74%) had good results, 4/23 (17%) fair and 2/23 (9%) with poor functional results.
A total of 1,661 pregnant women aged between 13 and 45 years were screened for bacteriuria by urine culture. Of the 1,661 culture results, 615 (37%) yielded no growth; 728 (43.8%) yielded no significant growth (presence of <10(5) organisms/ml urine of one or more types of bacteria); 286 (17.2%) yielded mixed growth (presence of >10(5) organisms/ml urine of more than one type of bacteria) and only 32 (1.9%) showed significant growth (presence of >10(5) organisms/ml urine of a single bacterium). Urine microscopy was also conducted. Two hundred and twenty-four (13.5%) specimens had >10 white blood cells/ml urine, of which 66 had >100 white blood cells; 13 were from the significant growth group. Three hundred and seventy-four (22.5%) specimens showed the presence of bacteria, 42 (2.5%) had red blood cells, 370 (22.3%) had epithelial cells, 58 (3.5%) had crystals, and 14 (0.8%) had yeasts. The most common bacterium isolated was Escherichia coli (12; 40%); the others included group B Streptococcus (5; 15%), Klebsiella spp (5; 15%), Diphtheroids (2), and Candida albicans (2). Fifty-two percent of tested strains were sensitive to ampicillin; 24 of 28 strains (85.7%) were sensitive to ciprofloxacin; all 7 strains tested were sensitive to nitrofurantoin and all 20 strains tested were sensitive to cotrimoxazole; 14/20 (70%) and 16/17 (94.1%) were sensitive to cephalexin and cefuroxime respectively. This study shows that asymptomatic bacteriuria does occur in pregnant women, albeit at a very low rate in an urban setting like Cheras. Urine microscopy is not specific and only serves as a guide to bacteriuria. The commonest causative organisms are those from the gastrointestinal tract and vagina. The antibiogram showed that cefuroxime and cephalexin are likely to be effective in treating bacteriuria: ampicillin must be reserved for Gram-negative organisms. For Gram-positive organisms, of which Group B Streptococcus is important, ampicillin is still effective in vitro. Nitrofurantion and cotrimoxazole have excellent activity in vitro and should be considered for therapy. 17.2% of the urine culture yielded mixed growth: likely to indicate that contamination of urine specimens still happens despite the strict instructions given to patients about the collection of a midstream urine specimen. Proper collection, appropriate transport, and the early processing of urine specimens remain essential.
