    INTRODUCTION: Many studies have revealed that exposure to secondhand smoke (SHS) substantially increases the risk of smoking related diseases especially among the vulnerable groups, yet data on the location of SHS exposure among youth in Malaysia are still lacking. The study aims to describe the prevalence and factors associated with SHS exposure at home, outside the home, and inside the school among school-going adolescents in Malaysia.

    METHODS: We derived the data from the TECMA study, which used a cross-sectional study design and multi-stage sampling method to obtain a representative sample of school-going adolescents aged 11-19 years in Malaysia in 2016. Data were collected through a self-administered approach using a pre-validated standard questionnaire. Descriptive and multivariate analyses were used to analyze the data, and results are presented as adjusted odds ratio (AOR) with 95% confidence interval (95% CI).

    RESULTS: SHS exposure for the past seven days was higher outside the home (51.2%; 95% CI: 49.2-53.2) compared to at home (37.8%; 95% CI: 35.8-39.9) while 27.3% (95% CI: 25.1-29.5) of school-going adolescents reported exposure to SHS inside the school in the past one month. In the regression analyses, older adolescents, those of Malay and Bumiputra Sarawak ethnicities, adolescents from rural areas and current smokers had higher likelihood of exposure to SHS at home, outside home and inside the school. Our study also found that adolescents who were current smokers had higher odds of being exposed to SHS at home (AOR=2.87; 95% CI: 2.57-3.21), outside the home (AOR=3.46; 95% CI: 3.05-3.92) and in the school (AOR=2.25; 95% CI: 2.01-2.51).

    CONCLUSIONS: Health promotion measures should target parents/guardians and household members to reduce SHS exposure among adolescents. In addition, smoke-free regulation should be fully enforced in school. Furthermore, more public places should be designated non-smoking areas to reduce SHS exposure and denormalize smoking behavior.

    Background: The investigation aimed to estimate the association between carbonated soft drink consumption frequency and externalizing and internalizing behaviour among university students in five ASEAN counties.

    Methods: A cross-sectional survey included 3353 university students from Indonesia, Malaysia, Myanmar, Thailand and Vietnam, median age 20 years (interquartile range 3 years).

    Results: In all five ASEAN countries, the study found a prevalence no soft drink consumption in the past 30 days of 20.3%, less than one time a day 44.7%, once a day 25.4% and two or more times a day 9.6%. In the adjusted logistic regression analysis, higher frequency of soft drink consumption (one and/or two or more times a day) was associated with externalizing behaviour (in physical fight, injury, current tobacco use, problem drinking, drug use, pathological internet use and gambling behaviour), and higher frequency of soft drink consumption (two or more times a day) was associated with depression in females, but no association was found for the general student population in relation to internalizing behaviour (depression, posttraumatic stress disorder, suicidal ideation, suicide plan, suicide attempt and sleeping problem).

    Conclusions: Findings suggest that carbonated soft drink consumption is associated with a number of externalizing but not internalizing health risk behaviours.

    Squamous cell carcinoma is the most common malignant neoplasm of the upper aerodigestive
    tract, and presentation is usually at the late stages when the diagnosis is made. Recurrence
    after 1st therapy is common especially in the locoregional area of the tumour. For cancers
    affecting the oral cavity, oropharynx, and mandible, “COMMANDO” (Combined
    Mandibulectomy and Neck Dissection Operation) is one of the surgical approaches which
    constitutes of primary tumour resection, mandibulectomy and neck dissection. We describe a
    case of rapid locoregional recurrence following 1st surgical procedure of bilateral tonsillectomy
    and extended neck dissection of oropharyngeal squamous cell carcinoma in a young healthy
    individual without history of alcohol and tobacco abuse involving the right buccal region which
    after positron emission tomography was done, showed involvement of right pterygoid muscles,
    right-sided tongue muscle, and right mandible. The patient underwent redo salvage surgery
    and reconstruction with anterolateral thigh flap.

    INTRODUCTION: Smoking is a modifiable risk factor for many diseases. The public should recognize the impact of smoking on their health and their wealth. The current study aimed to evaluate the cost burden of smoking to target Asia-Pacific countries.

    METHODS: The current study estimated the annual spending and lifetime spending of smokers in the target Asia-Pacific countries (Hong Kong, Malaysia, Thailand, South Korea, Singapore, and Australia) on purchasing cigarettes, as well as predicted the revenue that could be generated if smokers spent the money on investment instead of buying cigarettes. Smokers' spending on cigarettes and the potential revenue generated from investment were estimated based on the selling prices of cigarettes, Standards & Poor's 500 Index, and life expectancies of smokers. Data were extracted from reports released by the World Health Organization or government authorities.

    RESULTS: The annual expenses (in US$) on purchasing one pack of cigarettes, in decreasing order, were: Australia ($5628.30), Singapore ($3777.75), Hong Kong ($2799.55), Malaysia ($1529.35), South Korea ($1467.30), and Thailand ($657.00). The lifetime spending on purchasing one pack of cigarettes each day were: Australia ($308993.67), Singapore ($207398.48), Hong Kong ($151735.61 for male and $166853.18 for female), South Korea ($80261.31), Malaysia ($72338.26), and Thailand ($31207.50).

    CONCLUSIONS: The cost burden of smoking is high from a smoker's perspective. Smokers should recognize the high economic burden and quit smoking to enjoy better health and wealth.

    Cancers of the oral cavity are more common worldwide in men than in women, and the same is true for cancer of the nasopharynx region, whereby nasopharyngeal carcinoma (NPC) incidence rate in men is 2.5 times that in women. Different risk factors, including environmental, lifestyle and genetic factors, come into play in terms of contributing towards the development of these cancers. The increased incidence of oral cancers in developed countries in recent years are attributable to rises in the consumption of tobacco and/or alcoholic beverages, in addition to the traditional practice of betel quid chewing in some communities. As for NPC, the risk factors include male sex, overconsump-tion of preserved salted fish and smoking. In terms of etiology due to microbial agents, the human papillomavirus (HPV) has been linked with oral cancers whereby HPV DNA was found in about 2 out of 3 oropharyngeal cancer cases. In contrast, the Epstein-Barr virus (EBV) has been closely associated with most cases of NPC. Specifically, NPC is categorized by the WHO into two main histological types—keratinizing squamous cell carcinoma (type I) and non-keratinizing squamous cell carcinoma (types II and III), and it is the non-keratinizing type (types II and III) which has very high percentage of EBV DNA. The oncogenicity of these viruses had been studied extensively, and they are now recognized as crucial early triggers of NPC and oral cancers. Genetic factors can also predispose a person to the development of either oral cancer or NPC. Certain HLA class I alleles are associated with increased risks for NPC. Genetic polymorphisms in genes encoding the cytochrome P450 enzymes and glutathione S-transferase had been identified as potential risk factors for NPC. In our studies, we had shown that polymorphism in the XPD gene which encodes a DNA helicase enzyme involved in nucleotide excision repair was linked to risk for NPC in Malaysian population. We also found that the combination of CGC allele from hOGG1, ITGA2 and XPD polymorphisms was significantly associated with increased odds of NPC. In oral cancers, studies by other researchers revealed that gene polymorphisms in HOTAIR gene and the interaction with betel quid chewing are linked to oral cancer risk. Specific COX-2 gene polymorphisms were also found to be associated with increased risk for oral cancer development and progression. Taken together, these studies show a strong correlation between viral etiology combined with the indi-vidual’s genetic background coupled with certain risky lifestyle behaviours which together contribute towards the development of oral cancer and NPC.

    5-HT3R antagonists such as ondansetron, granisetron and tropisetron have been clinically used to treat nausea and vomiting in chemotherapy patients. However, current study and research revealed novel potentials of these ligands in other diseases like inflammation, Alzheimer's, and drug abuse. Towards utilising these drugs as anti-smoking agents to treat nicotine dependence problem, there are conflicting reports regarding the potential of these ligands in modulating the effects of nicotine in both human and animal behavioural studies. This is complicated by the heterogeneity of 5-HT3R itself, cross regulation between nicotinic acetylcholinergic receptor (nAChR) and distinct pharmacological profiles of 5-HT3R antagonists. This review gathered existing studies conducted investigating the potential of "-setron" class of 5-HT3R antagonists in modulating nicotine effects. We proposed that the mechanism where 5-HT3R antagonists mediate the effects of nicotine could be attributed by both direct at 5-HT3R and indirect mechanism in nicotine addiction downstream regulation. The indirect mechanism mediated by the 5-HT3R antagonist could be through α7 nAChR, 5-HT1B receptor (5-HT1BR), 5-HT1C receptor (5-HT1CR), calcineurin activity, p38 MAPK level, PPAR-γ and NF-κβ. Our review suggested that future studies should focus on newer 5-HT3R antagonist with superior pharmacological profile or the one with multitarget action rather than high selectivity at single receptor.

    Introduction: Initially, studies showed that graphic warning signs (GWSs) on cigarette packages encouraged smok- ing cessation. However, there have been recent concerns over the effectiveness of GWSs to change smoker percep- tions and behavior over time. Our goals were to assess the latest perceptions of GWSs among smokers in Kelantan and to determine the factors associated with them. Methods: This cross-sectional study was conducted among re- spondents who attended outpatient clinics in a teaching hospital in Kelantan. Their perceptions were analyzed with a validated Malay questionnaire containing four domains: fear, influence, credibility, and picture content. Results: The average smoking age was 17 (3.04) years old. The mean smoking time was 11 (7.49) years. The average daily cigarettes smoked was 8 (6.26). Most respondents perceived low levels of fear (83%), poor picture content (65.5%), low influence (87.6%), and low levels of credibility (70.1%) in GWSs. Those with low levels of education were significantly associated with poor perceptions of GWSs. Conclusion: Despite vigorous efforts by the government to discourage smoking in Kelantan, smokers still poorly perceive GWSs. More effective health-promotion strategies are essential to influence smokers in this area.

    AIMS: To present an updated overview on the safety of concurrent use of food, herbal or dietary supplement and warfarin.

    METHODS: A systematic literature review was performed on 5 databases from inception up to 31 December 2019. These interactions were classified depending on the likelihood of interaction and supporting evidences.

    RESULTS: A total of 149 articles describing 78 herbs, food or dietary supplements were reported to interact with warfarin. These reports described potentiation with 45 (57.7%) herbs, food or dietary supplements while 23 (29.5%) reported inhibition and 10 (12.8%) reported limited impact on warfarin pharmacokinetics and pharmacodynamics. Twenty unique herb and dietary supplements also reported to result in minor bleeding events, such as purpura and gum bleeding as well as major events such as intracranial bleeding that led to death.

    CONCLUSION: While most food, herbs and supplements can be safely taken in moderation, healthcare professionals should be aware of the increased risk of bleeding when taking several food and herbs. These include Chinese wolfberry, chamomile tea, cannabis, cranberry, chitosan, green tea, Ginkgo biloba, ginger, spinach, St. John's Wort, sushi and smoking tobacco. Patients should be counselled to continue to seek advice from their healthcare professionals when starting any new herbs, food or supplement.

    Exposure to secondhand smoke has consistently been linked to adverse health effects in children, including reduced lung function and various respiratory diseases. There is also increasing evidence that secondhand smoke exposure is associated with cognitive impairment and behavioral problems in children, This cross sectional study was done on 795 chiildren to determine the association between secondhand smoke exposure and peak expiratory flow rate (PEFR) and cognitive performance among the primary school children in Kota Bharu Kelantan. A questionnaire was used to obtain information on socio-demography and smoking status of the household. The PEER was measured using a child Mini Wright peak expiratory flow meter while cognitive performance was assessed by four subtests of Weschler Intelligence Scale For Children (WISC III). Data analysis was done using SPSS version 11. Children were classified as exposed to secondhand smoke when at least one househoH member smoked. There were 442 (55 .6%) children exposed to secondhand smoke at home. The mean (SD) PEFR for unexposed and exposed children were 266.18 (60.80) l/min and 266 .06 (57. 70) l/min respectively, The mean (SD) scores for Digit Span Forward, Digit Span Backward Coding and Arithmetic in unexposed chiMren were 6.84 (1.80), 4.Z7(1.68), 45.25 (9,99) and 8.04 (1.04) respectively. The mean (SD) scores for exposed children were 6.73 (1 .77). 4.07 (l .65), 45.1 I (1 I ,03) and 8.13 (1 .00) respectively. Multivariate analysis of variance showed no signincant dijference in the PEFR (p=O.816) and the cognitive scores between exposed and unexposed primary school children in Kota Bharu, Kelantan

    Introduction: The objective was to evaluate the perceived risks, barriers and stages of change on smoking cessation among the Malay male security guards. Materials and Methods: In the year 2004, a cross sectional survey was conducted on a group of security guards working in the campus and the hospital of a public university in Kuala Lumpur. Universal sampling (n=210) was conducted with a response rate of 88.6%. A self-administered questionnaire was used to survey the participants on their smoking status, stages of change, perceived risks and barriers to smoking cessation. Results: There were 37% current smokers and 23.7% ex-smokers. The mean year of smoking was 19.2 + 8.1 and the number of cigarettes smoked was 16.4 + 8.0 per day among the current smokers. About two-third of the smokers perceived the amount smoked currently was bad for health. However, only 23.3% and 30.9% of the smokers perceived themselves to be at higher risk for lung cancer and heart disease respectively. The three main reasons to quit smoking were health reasons, doctors’ advice and cost. The main barriers were addiction (53.3%) and stress (28.3%). Most of the smokers (42%) were in the pre-contemplation stage with half of them not having thoughts of quitting. Conclusion: The smokers had misperception on smoking and majority was at the pre-contemplation stage of change in smoking cessation. The findings of this survey add on to the existing literature about the perception of risks, barriers and stages of change to smoking cessation. This will provide valuable information on the planning and delivering of smoking cessation programmes in the local context.

    The aims of this study were to determine the prevalence and factors that influenced smoking behaviours among male adolescents in Kuantan, Pahang. A cross-sectional study was conducted among the form four male students in Kuantan District. Three hundred and twenty three students were randomly selected from eight secondary schools. A self-administered questionnaire was distributed to all the respondents. Almost half of the sample was smokers (45.8%) and half of them were Malays (53.1%). Students whose parents had lower level of occupation were more likely to smoke (58.8%). Among smokers, 34.5% of them smoked since primary school and a majority (91.7%) smoked 10 or less cigarettes per day. Half of them (53.4%) reported that they bought loose cigarettes and most of them used their school pocket money to purchase the cigarettes (81.7%). From the multivariate analysis, it was found that Non-Science Stream classes (OR=3.92, 95% CI= 2.10, 7.32), peers' smoking (OR=6.07, 95% CI= 2.32, 15.92), and attitude towards smoking (OR= 21.93, 95% CI= 9.71,49.51) were significantly associated with smoking habit. The prevalence of smoking among male adolescents was considerably high'in this population. It is recommended that antismoking activities in school be carried out regularly and should involve an active participation from the adolescents themselves since peers have great influence on smoking habits.

    Many studies on adolescent smoking have been conducted in Malaysia, but very limited information is available on smoking amongst lower secondary school male students (Forms 1 and 2). We present data from a baseline study in Kota Tinggi District, Johor on the psychosocial factors, stages of smoking acquisition and susceptibility to smoking initiation and their relationship to adolescent smoking. The study is the first wave of a 3-year longitudinal study which was conducted from March 2007 to May 2009, aimed to describe the prevalence of smoking among students in the lower secondary classes. A three stage stratified sampling was performed to obtain a sample. The Bogus Pipeline Method was employed to confirm smoking status. Prevalence of smoking was 35.5%. Smoking prevalence among students of schools located in the Federal Land Development Authority (FELDA) settlement areas (42.9%) was two-fold higher than in the rural and town schools combined (20.29%). Using the Fagerstrom scale, 90% of current smokers had lower addiction to nicotine. Smoking was associated with peer smoking [OR, 4.19 (95% CI, 2.57-6.82)], having a brother smoking [2.17 (1.31-3.61)], parental smoking [1.73 (1.17-2.80)] and locality where respondents attend school [1.94(1.11-3.39)]. The study indicates that, the prevalence of smoking was high in all areas especially FELDA settlement areas. Measures such as teaching of skills to resist social pressure to smoke, establishment of peer support groups and involvement of parents in anti-smoking programs are recommended to curb the high prevalence of smoking among lower secondary school students in Kota Tinggi.

    Introduction: The aim of this study is to determine the prevalence of otitis media with effusion (OME) in Malaysian children between three months to twelve years of age and to identify the risk factors associated with it.
    Materials and methods: This is a cross-sectional study consists of 153 children selected by stratified random sampling method. Parents of these children were interviewed with a structured questionnaire. Clinical examination, including otoscopic examination and tympanometry was performed for each child.
    Results: The prevalence of OME was 18.3%. There was no statistical significant relationship between OME and gender, race, household size, attendance to daycare center, breast feeding, and exposure to passive smoking, allergy, and asthma.
    Conclusion: The prevalence of OME is 18.3% in Malaysian children between three months to twelve years of age. Frequency of AOM is a statistically significant factor to the development of OME later in life. The different risk factors associated with OME are still controversial.

    Objective: The smoking rate among patients with mental health problem is higher than in the general population. Effective pharmacotherapy to treat nicotine addiction is thus needed to reduce the morbidity and mortality associated with cigarette smoking among these patients. This article reviews the literature on the suitability of varenicline for smokers with mental health problems.
    Methods: A search of the literature was conducted using PubMed from year 2001 to July 2009 using key words varenicline alone and varenicline and mental health. Articles chosen were narrowed to those published in English. The type of articles chosen included clinical trials, metaanalyses, case reports, and review articles.
    Results: The search produced a total of 322 articles on varenicline and 14 articles on varenicline and mental health. Varenicline, a new drug for smoking cessation is an α4β2 partial agonist and partial antagonist at nicotinic acetylcholine receptor. As a partial agonist, varenicline relieves craving and withdrawal symptoms that occur during smoking abstinence and also reduce the rewarding effects of smoking in patients who relapse. However, at present, there is concern regarding the neuropsychiatric side effects such as aggressive behaviour, suicidal ideation, mania and depression associated with varenicline use in patients with mental health problems, but these reports did not show a causal-link or lack of link between these symptoms and varenicline.
    Conclusion: Current available data support the effectiveness of varenicline to treat nicotine dependence. However its safety among smokers with mental health problems remains to be elucidated. At present, further safety assessment is needed in this patient population. Until new data is available regarding the safety of varenicline in these populations, psychiatrists and physicians prescribing this medication should be extra cautious and monitor for possible psychiatric side effects when prescribing this medication to patients with pre-existing psychiatric disorders or have vulnerability to psychoses.

    Objective: To examine the potential effects of lifestyle factors on male reproductive health. Evidence of a global decline in human sperm quality over recent decades has been accumulating. Environmental, occupational, and modifiable lifestyle factors may contribute to this decline. This review focuses on key lifestyle factors that are associated with male infertility such as smoking cigarettes, alcohol intake, use of illicit drugs, obesity, psychological stress, advanced paternal age, dietary practices, and coffee consumption. Other factors such as testicular heat stress, intense cycling training, lack of sleep and exposure to electromagnetic radiation from mobile phone use are briefly discussed.

    Materials and method: A comprehensive literature search was performed to identify and synthesise all relevant information, mainly from within the last decade, on the major lifestyle factors associated with male infertility and semen quality. Database searches were limited to reports published in English only. A manual search of bibliographies of the reports retrieved was conducted to identify additional relevant articles.

    Results: In all, 1012 articles were identified from the database search and after reviewing the titles and abstract of the reports, 104 articles met the inclusion criteria. Of these, 30 reports were excluded as the full-text could not be retrieved and the abstract did not have relevant data. The remaining 74 reports were reviewed for data on association between a particular lifestyle factor and male infertility and were included in the present review.

    Conclusion: The major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking conception.

    Introduction: According to the Youth Behaviour Risk Factor Surveillance (YBRFSS, 2011) in Malaysia, the prevalence of smokers nationally among Form 1, 2 and 4 students government secondary school students was 9.1% (ever smokers) and 8.7% (current smokers). However, there is limited information on the prevalence of smoking among religious secondary school students and self-esteem as risk factor. Thus, this study was conducted to determine the prevalence and factors associated with smoking among the religious secondary school students in Petaling district, Selangor.
    Methods: A cross-sectional study was conducted among 899 students. The schools were selected using cluster sampling and self-administered questionnaire was used. Data was analyzed using chi-square test and multivariate logistic regression to identify the independent factors for smoking.
    Results: The response rate was 94%. The prevalence of ever smoking was 10.1%; 3.9% among female and 18.6% among male. The median age (interquartile range) of smoking initiation was 12.00 (4.01) years. The results showed that independent factors for smoking were: males (OR= 5.47); age group 14-15 years (OR=2.82) and 16-17 years (OR=3.63) and having low self -esteem (OR=6.24).
    Conclusion: prevalence of ever smokers is higher when compared to YBRFSS, (2011) and it was revealed that most of the smokers started smoking even before secondary school. The results also revealed the importance of promoting self-esteem. Efforts in smoking prevention should therefore be focused on curbing the initiation of the acts and improving students’ self-worth.

    Background: Secondhand smoke (SHS) exposure has adverse effects on the cardiovascular system. This study aimed to determine the effects of SHS on the cardiovascular disease biomarkers, namely the metabolic, inflammatory, and oxidative stress markers in healthy adult women.

    Methods: This comparative cross-sectional study was conducted among healthy women. The cases included those women exposed to SHS, and the controls included those women not exposed to SHS. SHS exposure was defined as being exposed to SHS for at least 15 min for 2 days per week. Venous blood was taken to measure the metabolic markers (high molecular weight adiponectin, insulin level, insulin resistance, and nonesterified fatty acids), oxidative stress markers (oxidized low density lipoprotein cholesterol and 8-isoprostane), and inflammatory markers (high-sensitivity C-reactive protein and interleukin-6). A hair nicotine analysis was also performed. An analysis of covariance and a simple linear regression analysis were conducted.

    Results: There were 101 women in the SHS exposure group and 91 women in the non-SHS exposure group. The mean (with standard deviation) of the hair nicotine levels was significantly higher in the SHS exposure group when compared to the non-SHS exposure group [0.22 (0.62) vs. 0.04 (0.11) ng/mg; P = 0.009]. No significant differences were observed in the high molecular weight adiponectin, insulin and insulin resistance, nonesterified fatty acids, 8-isoprostane, oxidized low density lipoprotein cholesterol, interleukin-6, and high-sensitivity C-reactive protein between the two groups. The serum high molecular weight adiponectin was negatively associated with the insulin level and insulin resistance in the women exposed to SHS. However, no significant relationships were seen between the high molecular weight adiponectin and nonesterified fatty acids, 8-isoprostane, oxidized low density lipoprotein cholesterol, high-sensitivity C-reactive protein in the SHS group.

    Discussion: There were no significant differences in the metabolic, oxidative stress, and inflammatory markers between the SHS exposure and non-SHS exposure healthy women.

    Objectives: The aim of this study was to perform a systematic review of clinical practice guidelines to identify nonpharmacologic recommendations for osteoporosis treatment.

    Methods: A systematic review of literature following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-statement methodology for clinical practice guidelines was conducted; PROSPERO CRD42019138548. Assessment of selected clinical practice guidelines with the AGREE (Appraisal of Guidelines for Research & Evaluation)-II methodological quality instrument was performed, and those graded over 60 points were selected for recommendations extraction and evidence analysis.

    Results: Only 6 clinical practice guidelines fulfilled criteria, 69 nonpharmacological recommendations were extracted: 13 from American Association of Clinical Endocrinologists and American College of Endocrinology guideline, 16 from Malaysian Osteoporosis Society guideline, 15 from the Ministry of Health in Mexico guideline, 14 from Royal Australian College of General Practitioners guideline, 7 from Sociedad Española de Investigación Ósea y del Metabolismo Mineral guideline, and 7 from National Osteoporosis Guideline Group guideline. Percentage by theme showed that the highest number of recommendations were 12 (17.1%) for vitamin D, 11 (15.7%) for a combination of calcium and vitamin D, and 11 (15.7%) for exercise.

    Conclusions: These recommendations address integrating interventions to modify lifestyle, mainly calcium and vitamin D intake, and exercise. Other recommendations include maintaining adequate protein intake, identification and treatment of risk factors for falls, and limiting the consumption of coffee, alcohol and tobacco. Considerations on prescription must be taken.

    Production of tomato (Lycopersicon esculentum) in Bangladesh, Malaysia, Myanmar, Vietnam, and Laos has been severely affected by yellow leaf curl disease. Tomato leaf samples were collected from symptomatic tomato plants from farmers' fields in the five countries from 1997 to 1999. DNA was extracted from all samples, four from Vietnam, two each from Malaysia, Laos, and Myanmar, and seven from Bangladesh. Virus DNA was amplified by polymerase chain reaction (PCR) using the begomovirus-specific degenerate primer pair PAL1v 1978/PAR1c 715(1), which amplifies the top part of DNA A. All samples gave the expected 1.4-kb PCR product. The PCR product of one sample per country was cloned and sequenced. Based on the sequences of the 1.4-kb DNA products amplified by the first primer pair, specific primers were designed to complete each of the DNA A sequences. Computer-assisted sequence comparisons were performed with begomovirus sequences available in the laboratory at the Asian Vegetable Research and Development Center, Shanhua, Tainan, and in the GenBank sequence database. The five DNA species resembled DNA A of begomoviruses. For the detection of DNA B two degenerate primer pairs were used, DNABLC1/DNABLV2 and DNABLC2/DNABLV2 (DNABLC1: 5'-GTVAATGGRGTDCACTTCTG-3', DNABLC2: 5'-RGTDCACTT CTGYARGATGC-3', DNABLV2: 5'-GAGTAGTAGTGBAKGTTGCA-3'), which were specifically designed to amplify DNA B of Asian tomato geminiviruses. Only the virus associated with yellow leaf curl of tomato in Bangladesh was found to contain a DNA B component, which was detected with the DNABLC1/DNABLV2 primer pair. The DNA A sequence derived from the virus associated with tomato yellow leaf curl from Myanmar (GenBank Accession No. AF206674) showed highest sequence identity (94%) with tomato yellow leaf curl virus from Thailand (GenBank Accession No. X63015), suggesting that it is a closely related strain of this virus. The other four viruses were distinct begomoviruses, because their sequences shared less than 90% identity with known begomoviruses of tomato or other crops. The sequence derived from the virus associated with tomato yellow leaf curl from Vietnam (GenBank Accession No. AF264063) showed highest sequence identity (82%) with the virus associated with chili leaf curl from Malaysia (GenBank Accession No. AF414287), whereas the virus associated with yellow leaf curl symptoms in tomato in Bangladesh (GenBank Accession No. AF188481) had the highest sequence identity (88%) with a tobacco geminivirus from Yunnan, China (GenBank Accession No. AF240675). The sequence derived from the virus associated with tomato yellow leaf curl from Laos (GenBank Accession No. AF195782) had the highest sequence identity (88%) with the tomato begomovirus from Malaysia (GenBank Accession No. AF327436). This report provides further evidence of the great genetic diversity of tomato-infecting begomoviruses in Asia. Reference: M. R. Rojas et al. Plant Dis. 77:340, 1993.
