    Objectives: The objective of the study is to determine the prevalence of substance abuse for alcohol, cannabis, opiates, stimulants, solvent and other substances among patients with schizophrenia in Hospital Bahagia Ulu Kinta (HBUK), Perak , Central Peninsular of Malaysia. This study also aims to determine the association of substance abuse with aggression, the demographic characteristics and total duration of hospitalization.
    Methods: This was a retrospective cross-sectional study whereby the first 194 subjects diagnosed to have schizophrenia based on International Classification of Disease, 10th edition (ICD-10) criteria were taken from data registry of patients admitted to HBUK from January until February 2004. The subjects’ medical files were examined for documentation of substances abuse, aggression and accumulative duration of hospitalization.
    Results: The results showed the prevalence of substances misuse among patients with schizophrenia in general (including alcohol) was 24.7%. Cannabis 16.7%, alcohol 13.4%, opiates(heroin) 6.7%, Amphetamine type stimulants (amphetamine, metamphetamine, ecstacy) 5.7%, and other substances (benzodiazepine, solvents) 1.5%.
    Conclusion: There is higher prevalence of substance misuse in patients with schizophrenia as compared to general population. Male patients with history of substance misuse are more likely to have aggression than female. This group needs special precaution and probably in need of specialist help.

    RATIONALE & OBJECTIVE: Arteriovenous fistulas (AVFs) have been recommended as the preferred vascular access for pediatric patients on maintenance hemodialysis (HD), but data comparing AVFs with other access types are scant. We studied vascular access choice, placement, complications, and outcomes in children.

    STUDY DESIGN: Prospective observational cohort study.

    SETTING & PARTICIPANTS: 552 children and adolescents from 27 countries on maintenance HD followed up prospectively by the International Pediatric HD Network (IPHN) Registry between 2012 and 2017.

    PREDICTOR: Type of vascular access: AVF, central venous catheter (CVC), or arteriovenous graft.

    OUTCOME: Infectious and noninfectious vascular access complication rates, dialysis performance, biochemical and hematologic parameters, and clinical outcomes.

    ANALYTICAL APPROACH: Univariate and multivariable linear mixed models, generalized linear mixed models, and proportional hazards models; cumulative incidence functions.

    RESULTS: During 314 cumulative patient-years, 628 CVCs, 225 AVFs, and 17 arteriovenous grafts were placed. One-third of the children with an AVF required a temporary CVC until fistula maturation. Vascular access choice was associated with age and expectations for early transplantation. There was a 3-fold higher living related transplantation rate and lower median time to transplantation of 14 (IQR, 6-23) versus 20 (IQR, 14-36) months with CVCs compared with AVFs. Higher blood flow rates and Kt/Vurea were achieved with AVFs than with CVCs. Infectious complications were reported only with CVCs (1.3/1,000 catheter-days) and required vascular access replacement in 47%. CVC dysfunction rates were 2.5/1,000 catheter-days compared to 1.2/1,000 fistula-days. CVCs required 82% more revisions and almost 3-fold more vascular access replacements to a different site than AVFs (P<0.001).

    LIMITATIONS: Clinical rather than population-based data.

    CONCLUSIONS: CVCs are the predominant vascular access choice in children receiving HD within the IPHN. Age-related anatomical limitations and expected early living related transplantation were associated with CVC use. CVCs were associated with poorer dialysis efficacy, higher complication rates, and more frequent need for vascular access replacement. Such findings call for a re-evaluation of pediatric CVC use and practices.

    RATIONALE & OBJECTIVE: Research on pediatric kidney replacement therapy (KRT) has primarily focused on Europe and North America. In this study, we describe the mortality risk of children treated with maintenance peritoneal dialysis (MPD) in different parts of the world and characterize the associated demographic and macroeconomic factors.

    STUDY DESIGN: Prospective cohort study.

    SETTING & PARTICIPANTS: Patients younger than 19 years at inclusion into the International Pediatric Peritoneal Dialysis Network registry, who initiated MPD between 1996 and 2017.

    EXPOSURE: Region as primary exposure (Asia, Western Europe, Eastern Europe, Latin America, North America, and Oceania). Other demographic, clinical, and macroeconomic (4 income groups based on gross national income) factors also were studied.

    OUTCOME: All-cause MPD mortality.

    ANALYTICAL APPROACH: Patients were observed for 3 years, and the mortality rates in different regions and income groups were calculated. Cause-specific hazards models with random effects were fit to calculate the proportional change in variance for factors that could explain variation in mortality rates.

    RESULTS: A total of 2,956 patients with a median age of 7.8 years at the start of KRT were included. After 3 years, the overall probability of death was 5%, ranging from 2% in North America to 9% in Eastern Europe. Mortality rates were higher in low-income countries than in high-income countries. Income category explained 50.1% of the variance in mortality risk between regions. Other explanatory factors included peritoneal dialysis modality at start (22.5%) and body mass index (11.1%).

    LIMITATIONS: The interpretation of interregional survival differences as found in this study may be hampered by selection bias.

    CONCLUSIONS: This study shows that the overall 3-year patient survival on pediatric MPD is high, and that country income is associated with patient survival.

    The United Nations General Assembly adopted the 2030 Agenda for Sustainable Development in November 2015 which included a set of 17 measurable "sustainable development goals" (SDGs). The SDGs included targets to end preventable deaths of newborns and children under 5 years of age by 2030, universal health care coverage, reduction of premature mortality from noncommunicable diseases (NCDs) by 33% as well as support the development and research for medicines for both communicable and NCDs. Although some successes were achieved in combating communicable diseases and improved childhood mortality rates, health systems in Asia are generally characterized by lack of accurate epidemiological information on congenital disorders, lack of human and financial resources, and inadequate focus on public health strategies to ensure targeted interventions, low level knowledge on congenital disorders amongst the community and healthcare providers and the ethical dilemma of managing rare congenital disorders in an environment of low national health expenditures. These bottlenecks must be addressed systematically and interventions such as the use of innovative epidemiological tools to overcome lack of data, increased efforts to standardize rare disease nomenclature and classification and renewed interest in birth defects registries by countries in the region must be considered. Targeted curative and public health approaches currently used in thalassaemia and neural tube defects may be used for other congenital disorders in Asian countries. The implementation of congenital disorders-related research, prevention, care, and treatment delivery services must be integrated into existing health systems in order to be effective to achieve the targets of SDG2030.

    Our objective was to determine the survival and prognostic factors of motor neuron disease (MND) in a multi-ethnic cohort of Malaysian patients. All patients seen at a university medical centre between January 2000 and December 2009 had their case records reviewed for demographic, clinical and follow-up data. Mortality data, if unavailable from records, were obtained by telephone interview of relatives or from the national mortality registry. Of the 73 patients, 64.4% were Chinese, 19.2% Malays and 16.4% Indians. Male: female ratio was 1.43: 1. Mean age at onset was 51.5 + 11.3 years. Onset was spinal in 75.3% and bulbar in 24.7% of the patients; 94.5% were ALS and 5.5% were progressive muscular atrophy (PMA). Overall median survival was 44.9 + 5.8 months. Ethnic Indians had shorter interval from symptom onset to diagnosis and shorter median survival compared to non-Indians. On Cox proportional hazards analysis, poor prognostic factors were bulbar onset, shorter interval from symptom onset to diagnosis and worse functional score at presentation. In conclusion, age of onset and median survival duration are similar to previous reports in Asians. Clinical features and prognostic factors are similar to other populations. In our cohort, ethnic Indians had more rapid disease course accounting for their shorter survival.

    BACKGROUND AND OBJECTIVES: Understanding the nature and pattern of young coronary artery disease (CAD) is important due to the tremendous impact on these patients' socio-economic and physical aspect. Data on young CAD in the southeast Asian region is rather patchy and limited. Hence we utilized our National Cardiovascular Disease Database (NCVD)-Percutaneous Coronary Intervention (PCI) Registry to analyze young patients who underwent PCI in the year 2007 to 2009.

    DESIGN AND SETTINGS: This is a retrospective study of all patients who had undergone coronary angioplasty from 2007 to 2009 in 11 hospitals across Malaysia.

    METHODS: Data were obtained from the NCVD-PCI Registry, 2007 to 2009. Patients were categorized into 2 groups-young and old, where young was defined as less than 45 years for men and less than 55 years for women and old was defined as more than or equals to 45 years for men and more than or equals to 55 years for women. Patients' baseline characteristics, risk factor profile, extent of coronary disease and outcome on dis.charge, and 30-day and 1-year follow-up were compared between the 2 groups.

    RESULTS: We analyzed 10268 patients, and the prevalence of young CAD was 16% (1595 patients). There was a significantly low prevalence of Chinese patients compared to other major ethnic groups. Active smoking (30.2% vs 17.7%) and obesity (20.9% vs 17.3%) were the 2 risk factors more associated with young CAD. There is a preponderance toward single vessel disease in the young CAD group, and they had a favorable clinical outcome in terms of all-cause mortality at discharge (RR 0.49 [CI 0.26-0.94]) and 1-year follow-up (RR 0.47 [CI 0.19-1.15]).

    CONCLUSION: We observed distinctive features of young CAD that would serve as a framework in the primary and secondary prevention of the early onset CAD.

    BACKGROUND: Coronary artery disease (CAD) is one of the leading causes of death in Malaysia. However, the prevalence of CAD in males is higher than in females and mortality rates are also different between the two genders. This suggest that risk factors associated with mortality between males and females are different, so we compared the clinical characteristics and outcome between male and female STEMI patients.

    OBJECTIVES: To identify the risk factors associated with mortality for each gender and compare differences, if any, among ST-elevation myocardial infarction (STEMI) patients.

    DESIGN: Retrospective analysis.

    SETTINGS: Hospitals across Malaysia.

    PATIENTS AND METHODS: We analyzed data on all STEMI patients in the National Cardiovascular Database-Acute coronary syndrome (NCVD-ACS) registry for the years 2006 to 2013 (8 years). We collected demographic and risk factor data (diabetes mellitus, hypertension, smoking status, dyslipidaemia and family history of CAD). Significant variables from the univariate analysis were further analysed by a multivariate logistic analysis to identify risk factors and compare by gender.

    MAIN OUTCOME MEASURES: Differential risk factors for each gender.

    RESULTS: For the 19484 patients included in the analysis, the mortality rate over the 8 years was significantly higher in females (15.4%) than males (7.5%) (P < .001). The univariate analysis showed that the majority of male patients < 65 years while females were >=65 years. The most prevalent risk factors for male patients were smoking (79.3%), followed by hypertension (54.9%) and diabetes mellitus (40.4%), while the most prevalent risk factors for female patients were hypertension (76.8%), followed by diabetes mellitus (60%) and dyslipidaemia (38.1%). The final model for male STEMI patients had seven significant variables: Killip class, age group, hypertension, renal disease, percutaneous coronary intervention and family history of CVD. For female STEMI patients, the significant variables were renal disease, smoking status, Killip class and age group.

    CONCLUSION: Gender differences existed in the baseline characteristics, associated risk factors, clinical presentation and outcomes among STEMI patients. For STEMI females, the rate of mortality was twice that of males. Once they reach menopausal age, when there is less protection from the estrogen hormone and there are other risk factors, menopausal females are at increased risk for STEMI.

    LIMITATION: Retrospective registry data with inter-hospital variation.

    Birth defects are one of the leading causes of paediatric disability and mortality in developed and developing countries. Data on birth defects from population-based studies originating from developing countries are lacking. One of the objectives of this study was to determine the epidemiology of major birth defects in births during the perinatal period in Kinta district, Perak, Malaysia over a 14-month period, using a population-based birth defect register. There were 253 babies with major birth defects in 17,720 births, giving an incidence of 14.3/1000 births, a birth prevalence of 1 in 70. There were 80 babies with multiple birth defects and 173 with isolated birth defects. The exact syndromic diagnosis of the babies with multiple birth defects could not be identified in 18 (22.5%) babies. The main organ systems involved in the isolated birth defects were cardiovascular (13.8%), cleft lip and palate (11.9%), clubfeet (9.1%), central nervous system (CNS) (including neural tube defects) (7.9%), musculoskeletal (5.5%) and gastrointestinal systems (4.7%), and hydrops fetalis (4.3%). The babies with major birth defects were associated with lower birth weights, premature deliveries, higher Caesarean section rates, prolonged hospitalization and increased specialist care. Among the cohort of babies with major birth defects, the mortality rate was 25.2% during the perinatal period. Mothers with affected babies were associated with advanced maternal age, birth defects themselves or their relatives but not in their other offspring, and significantly higher rates of previous abortions. The consanguinity rate of 2.4% was twice that of the control population. It is concluded that a birth defects register is needed to monitor these developments and future interventional trials are needed to reduce birth defects in Malaysia.

    Introduction: Various suture materials and suture techniques are used to perform gastrointestinal anastomosis after tumour resection, but the best combination is still a matter of debate.

    Methods: This multi-centre, international, single-arm, prospective observational study aimed at demonstrating the non-inferiority of a mid-term absorbable monofilament in comparison to braided sutures in gastrointestinal anastomosis. Monosyn suture was used to create the gastrointestinal anastomosis and the frequency of anastomotic leakage until day of discharge was chosen as the primary parameter. The outcome was compared to the results published for braided sutures in the literature. Secondary parameters were the time to perform the anastomosis, length of hospital stay, costs, and postoperative complications.

    Results: The anastomosis leakage rate was 2.91%, indicating that Monosyn suture was not inferior to braided sutures used in gastrointestinal anastomosis. Of the reported anastomotic suture techniques, the single layer continuous method was the fastest and most economical technique in the present observational study.

    Conclusion: Monosyn suture is safe and effective in gastrointestinal anastomosis and represents a good alternative to other sutures used for gastrointestinal anastomosis. With regard to safety, time and cost-efficiency, the single-layer continuous technique should be considered a preferred method. The transfer of results from clinical studies into daily practice with regard to surgical techniques for gastrointestinal anastomosis should be further evaluated in larger studies or in nationwide registries.

    INTRODUCTION AND METHODS: Cardiovascular diseases have progressively increased in importance as a major contributor of morbidity and mortality in Asia. However, many countries in Asia do not have nationwide systematically-collected and standardised data on myocardial infarction (MI). To accurately document the extent of atherosclerotic coronary heart disease in Singapore, a nationwide myocardial infarct registry was established in the mid-1986. Possible myocardial infarct events were identified through daily national lists of cardiac enzymes, hospital discharge codes, mortuary records and the national death registry. Data obtained from clinical history, cardiac enzymes and 12-lead electrocardiogram Minnesota codes were entered into an algorithm based on the WHO MONICA study. Cases identified as "definite" MI were included in the decade's review for this study.

    RESULTS: From 1988 to 1997, 13,048 myocardial infarct events were diagnosed with 3367 deaths. There was a 39.1% decline in mortality, with an average decline of 6.5% per year [95% confidence intervals (CI), -3.9% to -9.1%]. However, the decline in incidence was only 20.8% with an average decline of 2.4% per year (95% CI, -6.6% to -1.2%). The highest incidence and mortality rates for both genders were seen in the Indians, followed by the Malays and the Chinese.

    CONCLUSION: Over 10 years, from 1988 to 1997, we documented a significant fall in mortality from MI in Singapore. There was a smaller decline in the incidence of infarction. Singapore implemented a National Healthy Lifestyle Programme in 1992 as a 10-year effort. The disparity in the incidence and mortality may suggest that a more dramatic and immediate impact has taken place in mortality through therapeutic programmes; primary preventive programmes would be more difficult to evaluate and have a more gradual impact. Only with continual accurate data collection through the whole country, over a much longer period, can the relative value of preventive and therapeutic programmes in coronary heart disease be assessed.

    INTRODUCTION: This is the first prospective cohort study in Singapore to describe the incidence of ischaemic heart disease (IHD) and stroke among Chinese, Malays and Asian Indians.

    MATERIALS AND METHODS: The Singapore Cardiovascular Cohort Study is a longitudinal follow-up study on a general population cohort of 5920 persons drawn from 3 previous cross-sectional surveys. Morbidity and mortality from IHD and stroke were ascertained by record linkage using a unique identification number with the death registry, Singapore Myocardial Infarct Registry and in-patient discharge databases.

    RESULTS: There were 193 first IHD events and 97 first strokes during 52,806 person-years of observation. The overall incidence of IHD was 3.8/1000 person-years and that of stroke was 1.8/1000 person-years. In both males and females, Indians had the highest IHD incidence, followed by Malays and then Chinese. For males after adjusting for age, Indians were 2.78 times (95% CI 1.86, 4.17; P < 0.0001) and 2.28 times (95% CI 1.34, 3.88; P = 0.002) more likely to get IHD than Chinese and Malays respectively. For females after adjusting for age, Indians were 1.97 times (95% CI 1.07, 3.63; P = 0.03) and 1.37 times (95% CI 0.67, 2.80; P = 0.39) more likely to get IHD than Chinese and Malays respectively. For stroke, male Chinese and Indians had higher incidence than Malays (though not statistically significant). However, in females, Malays had the highest incidence of stroke, being 2.57 times (95% CI 1.31, 5.05; P = 0.008) more likely to get stroke than Chinese after adjustment for age.

    CONCLUSIONS: This prospective study of both mortality and morbidity has confirmed the higher risk of IHD in Indians. It has also found that Malay females have a higher incidence of stroke, which deserves further study because of its potential public health importance.

    Significant advances in diagnosis and management have cured the majority of children with cancer. In the leukaemias, the commonest childhood malignancy, intensive induction-consolidation is important to ensure a lasting cure in about 65-80% and to eliminate the traditionally bad prognostic risk factors associated with less intensive treatment. Bone marrow transplantation (BMT) has a curative role in the minority who relapse particularly while on treatment. With few exceptions, most paediatric solid tumours are curable. Although the multimodal approach is responsible for the progress made, chemotherapy has emerged to play a dominant role. It has, in several tumours, obviated or reduced the need for radiotherapy and/or surgery. In Wilms' tumour and Hodgkin's disease, refinement of treatment is now in progress to reduce therapy-related morbidity while not sacrificing efficacy.

    Objective: Native fistula creation for hemodialysis in patients who have exhausted all their superficial veins presents a challenge to vascular practice. We review our experience in transposed basilic vein fistula (BVT) creation and its usage for hemodialysis. Materials and Methods: We analyzed the hospital operative registry from January 2009 till June 2012 to identify the total number of BVT created in our center. Medical records of all patients were traced, and patients were interviewed using a standard proforma. In our center, BVT is performed as a two-stage procedure. All patients were routinely assessed with duplex scan preoperatively and postoperatively. Results: Two hundred thirty-nine patients were recruited in the study. Of these patients, 50.6% were male and 49.4% were female. Mean age was 53.4 years. Of these patients, 81.2% had history of other previous fistula creation. Risk factors profile includes diabetes mellitus in 59.8%, hypertension in 86.2%, and smoking in 13.0%. Of these patients, 84.5% had no operative complication. Commonest complication was wound infection, 6.3%, followed by hemorrhage or hemotoma required surgical intervention, 5.9%, and pseudoaneurysm, 1.3%. Primary and secondary patencies were at 84.2% and 86.1% at 1 year and 67.7% and 70.5% at 3 years, respectively. Conclusion: BVT is a credible option for challenging patients with absence of superficial veins for native fistula creation with good patency and low operative complication rate. Preoperative ultrasound assessment improves patient selection and outcome of BVT.

    The aim was to study the prevalence and sociodemographic features of odontogenic, non-odontogenic and salivary glands lesions among patients seen in Hospital Universiti Sains Malaysia. This information is essential to assist clinician in formulating reliable differential diagnosis of such lesion. Data on patient demographics, lesion location, tissue of origin and microscopic diagnosis were extracted from the Laboratory and Diagnosis record registries for biopsy specimen accessioned from year 2000 to 2012. This data was subsequently analyzed based on World Health Organization Classification of Head and Neck Tumours (2005). A total of 748 cases were included in the study. Out of the total number of cases, 367 cases were males and 377 cases were females. Ninety seven cases (13%) were of odontogenic origin, while 90 cases (12%) and 197 cases (26%) were of non-odontogenic and salivary gland origin respectively. Forty five percent of cases involved oral mucosal lesions. The most prevalent odontogenic lesion reported within the twelve years period was radicular cyst and ameloblastoma. Non-odontogenic bone lesion was rarely encountered with it making up less than two percent of total cases reported. Pleomorphic adenoma was the most prevalent benign salivary glands neoplasm reported within similar time period.

    PURPOSE: The study aims to identify, describe, and organize the currently available evidence regarding hip fracture (HF) registries in low- and middle-income countries (LMICs).

    METHODS: We conducted a scoping review adhering to PRISMA-ScR guidelines. We searched MEDLINE (PubMed), Google Scholar, Global Index Medicus, websites related to HF, and study references for eligible studies. Two reviewers independently performed the study selection and data extraction, including studies describing the use of individual patient records with the aim to improve the quality of care in older people with HF in LMICs.

    RESULTS: A total of 222 abstracts were screened, 59 full-text articles were reviewed, and 10 studies regarding 3 registries were included in the analysis. Malaysia and Mexico implemented a HF registry in public hospitals whereas Argentina implemented a registry in the private setting. The Mexican registry, the most recent one, is the only one that publishes annual reports. There was significant variability in data fields between registries, particularly in functional evaluation and follow-up. The Ministry of Health finances the Malaysian registry, while Argentinian and Mexican registries founding was unclear.

    CONCLUSION: The adoption of HF registries in LMICs is scarce. The few experiences show promising results but higher support is required to develop more registries. Long-term sustainability remains a challenge.

    The objective of this study was to investigate suicide trends in Singapore between 1955 and 2004. Suicide cases were identified from the Registry of Birth and Death, Singapore, and analyzed using Poisson regression. Overall, suicide rates in Singapore remained stable between 9.8-13.0/100,000 over the last 5 decades. Rates remain highest in elderly males, despite declines among the elderly and middle-aged males in recent years. Rates in ethnic Chinese and Indians were consistently higher than in Malays. While the rates among female Indians and Chinese have declined significantly between 1995 and 2004, some increase was noted in female Malays. Although there was no increase in overall suicide rates, risk within certain population segments has changed over time.

    PURPOSE: To study the prevalence of second eye cataract surgery (SECS), trend in time interval between subsequent surgeries over the years, and factors associated with SECS utilization among patients who underwent cataract surgeries in the Ministry of Health (MOH), Malaysia.

    DESIGN: Secondary cross-sectional analysis of the Malaysian National Eye Database (NED) data.

    METHODS: The Malaysian Cataract Surgery Registry collected data on patients who had cataract surgery from 2002-2004 and 2007-2012. Data collected included demography, operative events, time interval between 2 surgeries, and postoperative visual outcomes. Descriptive analysis was performed.

    RESULTS: Total surgeries increased from 11,954 in 2002 to 30,265 in 2012 with a proportionate increase in SECS (30.7% in 2002 to 34.3% in 2012). Poor vision (<6/12) was reduced from 81.1% to 14.2% after surgery. With improved data capturing, missing data reduced from 29.22% to 1.05%. The time interval between surgeries was 10.58 months in 2002 and 14.49 months in 2012. Malays (40.2%) and those aged 61-70 years (38.1%) had the highest number of SECS. Those aged 40-50 years (10.96 months) and with poorer vision (9.97 months) had the shortest time interval between the 2 surgeries. The commonest surgical method was phacoemulsification (72.3%). Negeri Sembilan State had the highest SECS rate (35.91%) and Melaka had the shortest interval between surgeries (10.15 months).

    CONCLUSIONS: Despite an increase in the number of SECS, the time interval is still long. Poor presenting second eye vision and disparity among different states warrants the health authority's attention and intervention.

    Retinopathy of prematurity (ROP) is one of the most important causes of childhood blindness worldwide. The trend of ROP in Malaysia was unclear because there was no national registry before 2002. The purpose of this study is to analyze ROP students of different ages in the schools for the blind in Malaysia in order to evaluate the trend of ROP from 1992 to 2001. Data were obtained from a previous survey of 24 blind schools. It was found that 78 students or 17.4% were blind/severely visual impaired as a result of ROP. There was a significant surge in the number of ROP students who were born in 1994 when the use of synthetic surfactants was first introduced in Malaysia; otherwise there was no increasing trend in the number of students with ROP. However, the percentage of ROP in total was increasing, which indicates that ROP is becoming a more important cause of childhood blindness in this country.

    Chronic carriers of Salmonella Typhi act as reservoirs for the organism and become the agents of typhoid outbreaks in a community. In this study, chronic carriers in Kelantan, Malaysia were first identified using the culture and polymerase chain reaction method. Then, a novel serological tool, designated Typhidot-C, was evaluated in retrospect using the detected individuals as control positives. Chronic carriage positive by the culture and polymerase chain reaction method was recorded at 3.6% (4 out of 110) among individuals who previously had acute typhoid fever and a 9.4% (10 out of 106) carriage rate was observed among food handlers screened during outbreaks. The Typhidot-C assay was able to detect all these positive carriers showing its potential as a viable carrier screening tool and can be used for efficient detection of typhoid carriers in an endemic area. These findings were used to establish the first carrier registry for S Typhi carriers in Malaysia.
