Sreeramareddy CT, Harsha Kumar HN, Arokiasamy JT

BMC Infect Dis, 2013;13:16.
PMID: 23324535 DOI: 10.1186/1471-2334-13-16

BACKGROUND: Knowledge about symptoms and transmission of tuberculosis determines health seeking behavior and helps in prevention of tuberculosis transmission in the community. Such data is useful for policy makers to formulate information, education and communication strategies for tuberculosis control.
METHODS: A secondary data analysis of India demographic and health survey, 2005/6 was carried out. Questions about self-reported tuberculosis, transmission and curability of tuberculosis were analysed. Correct knowledge (without misconceptions) about tuberculosis transmission was used as a dependant variable and the explanatory variables tested were: demographic data, education, wealth quintiles, frequency of exposure to media and the curability of tuberculosis. Determinants of correct knowledge without misconceptions were tested by univariate and multivariate analyses using national weighting factor to adjust for complex sampling design.
RESULTS: A total of 109,070 households (response rate of 93.5%) and 198,718 participants (response rate of 91.6%) completed the survey. The samples of men and women interviewed were 74,360 and 124,358 respectively. Prevalence rate of self-reported tuberculosis was 445 per 100,000 usual household residents and 4.60 per 1,000 participants. The number of respondents who had "heard of an illness called tuberculosis" was 177,423 (89.3%). Of these 47,487 (26.8%) participants did not know and 55.5% knew about the correct mode of tuberculosis transmission i.e. "Through the air when coughing or sneezing". The common misconceptions about transmission were "Through food" (32.4%), "Sharing utensils" (18.2%), and "Touching a person with tuberculosis" (12.3%). Only 52,617 (29.7%) participants had correct knowledge without misconceptions. Being male (aOR 1.17, 95% CIs 1.14, 1.21), being a Hindu (aOR 1.20, 95% CIs 1.14, 1.26) or Muslim (aOR 1.26, 95% CIs 1.18, 1.34), listening to radio (aOR 1.08, 95% CIs 1.04, 1.13) and "Tuberculosis can be cured" (aOR 1.47, 95% CIs 1.41, 1.53) were associated with correct knowledge without misconceptions.
CONCLUSIONS: Knowledge about tuberculosis transmission is very poor and misconceptions still exist. Among the traditional mass media, the frequency of listening to radio was associated with correct knowledge about tuberculosis transmission. Strategies to deliver information, education and communication campaigns could be improved.

Al-Naggar RA, Jawad AA, Bobryshev YV

Asian Pac J Cancer Prev, 2012;13(11):5539-43.
PMID: 23317214

OBJECTIVE: The smoking prevalence in Malaysia is high, especially among men and adolescents. This study aimed to determine the prevalence and associated factors towards cigarette smoking among school teachers in Malaysia.
METHODOLOGY: This study was a school-based cross-sectional study conducted among 495 secondary school teachers. The questionnaire used in this study consisted of 29 questions categorized into two sections: socio-demographic characteristics and smoking behaviour. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) program 13.0. ANOVA; t-tests were used in univariate analysis; multiple linear regression was applied for multivariate analysis.
RESULTS: The majority of the participants were female (81.6%), in the age group ranged between 30-39 years (44%), Malay (90.1%), married (89.7%), degree holders (85.1%), with monthly income ranged between 3000-3999 Ringgit Malaysia (33.5%), from urban areas (94.7%), their specialty is social studies (33.9%) and with no family history of cancer (83.6%). The prevalence of smoking among school teachers in Malaysia was found to be 7.8%. Regarding reasons to start smoking among school teachers: the major reason was found to be relaxation (33.3%), followed by stress-relief (28.2%). Univariate analysis showed that sex, educational status, monthly income and residency were significantly associated with smoking among school teachers (p<0.001, p=0.004, p=0.031, p=0.010; respectively). Multivariate analysis showed that gender and marital status were significantly associated with smoking among school teachers (p<0.001, p=0.033; respectively).
CONCLUSION: The prevalence of smoking among school teachers in Malaysia was found to be relatively low. Sex, marital status, educational status, monthly income and residency were significantly associated with smoking among school teachers.

Fulltext Differences in the pattern of gastric carcinoma between north-eastern and north-western peninsular Malaysia: a reflection of Helicobacter pylori prevalence

Gurjeet K, Subathra S, Bhupinder S

Med J Malaysia, 2004 Oct;59(4):560-1.
PMID: 15779598 MyJurnal

A retrospective study on demographics of gastric carcinoma was conducted in Hospital Pulau Pinang (HPP) with the aim of comparing it to a previous study done in Hospital Universiti Sains Malaysia (HUSM), Kelantan. The incidence of gastric carcinoma was much higher in Penang compared to Kelantan. It was commonest in males and Chinese. The incidence and site of gastric carcinoma closely parallels Helicobacter pylori infection rates. This was evidenced by the higher incidence and non-cardia location of gastric carcinomas in an area with higher H. pylori infection rates (HPP) compared to a much lower incidence and preponderance of cardia tumours in HUSM where the H. pylori infection rate is exceptionally low.

Ampil ER, Fook-Chong S, Sodagar SN, Chen CP, Auchus AP

Alzheimer Dis Assoc Disord, 2005 Oct-Dec;19(4):184-5.
PMID: 16327344

The diversity of Singapore's population affords a unique opportunity to study ethnic variability in the dementias. We sought to explore the effects of ethnicity on the frequency of Alzheimer disease and vascular dementia in a large Singaporean sample. A total of 357 patients were studied: 190 with vascular dementia and 167 with Alzheimer disease. Vascular dementia was more common among Chinese and Malays, whereas Alzheimer disease was more common in Indians and Eurasians. Factors that may contribute to the observed ethnic variability in dementia etiologies include differential frequency of the ApoE-e4 allele, frequency of vascular risk factors, lifestyle choices, and cultural attitudes toward health care utilization.

Occlusal status in Asian male adults: prevalence and ethnic variation

Soh J, Sandham A, Chan YH

Angle Orthod, 2005 Sep;75(5):814-20.
PMID: 16279828

The purpose of this study was to determine the occlusal status in young Asian male adults of three ethnic groups. Study models of a sample of male army recruits (N = 339, age 17-22 years) with no history of orthodontic treatment were assessed. The ethnic proportions of the sample were Chinese 76.1% (n = 258), Malay 17.7% (n = 60), and Indian 6.2% (n = 21). British Standard Institute (BSI) and Angle's classification were used to determine incisor and molar relationships, respectively. Chi-square test or Fisher's Exact test was performed to compare the occlusal traits between ethnic groups. The distribution of incisor relationships of the total sample consisted of Class I = 48.1%, Class II/1 = 26.3%, Class II/2 = 3.2%, and Class III = 22.4%. Right Angle's molar relationships were 49.9%, 24.5%, and 24.2% whereas left Angle's molar relationships were 53.1%, 25.1%, and 21.2% for Class I, II, and III, respectively. Comparison between ethnic groups found that Indian subjects were more likely to have Class II/1 malocclusions and clinically missing permanent teeth (P < .05). The study found that the overall prevalence of malocclusion (BSI) was Class I, Class II/1, Class III, and Class II/2 in descending order of proportions. Angle's Class I molar was most prevalent followed by Class II and Class III relations. A significant difference in occlusal status between the ethnic groups was found regarding incisor relationship and missing permanent teeth (P < .05).

Khairi MD, Din S, Shahid H, Normastura AR

J Laryngol Otol, 2005 Sep;119(9):678-83.
PMID: 16156907

The objective of this prospective study was to report on the prevalence of hearing impairment in the neonatal unit population. From 15 February 2000 to 15 March 2000 and from 15 February 2001 to 15 May 2001, 401 neonates were screened using transient evoked otoacoustic emissions (TEOAE) followed by second-stage screening of those infants who failed the initial test. Eight (2 per cent) infants failed one ear and 23 (5.74 per cent) infants failed both ears, adding up to 7.74 per cent planned for second-stage screening. Five out of 22 infants who came for the follow up failed the screening, resulting in a prevalence of hearing impairment of 1 per cent (95 per cent confidence interval [95% CI]: 0.0-2.0). Craniofacial malformations, very low birth weight, ototoxic medication, stigmata/syndromes associated with hearing loss and hyperbilirubinaemia at the level of exchange tranfusion were identified to be independent significant risk factors for hearing impairment, while poor Apgar scores and mechanical ventilation of more than five days were not. In conclusion, hearing screening in high-risk neonates revealed a total of 1 per cent with hearing loss. The changes in the risk profile indicate improved perinatal handling in a neonatal population at risk for hearing disorders.

Diagnosis and management of Duchenne muscular dystrophy in a developing country over a 10-year period

Thong MK, Bazlin RI, Wong KT

Dev Med Child Neurol, 2005 Jul;47(7):474-7.
PMID: 15991868

Clinical data on Duchenne muscular dystrophy (DMD) are lacking in developing countries. The objective of this study was to delineate the demographic characteristics, investigations, and outcome of 21 Malaysian males diagnosed with DMD over a period of 10 years. Mean age presentation was 3 years 8 months (SD 23mo; range 10 to 84mo), mean duration from first presentation to diagnosis was 3y 7mo (SD 26mo; range 5 to 84) and the mean age for loss of ambulation was 11 years (SD 25mo; range 102 to 168). There was family history of DMD in five of the 21 patients. Muscle biopsy showed confirmatory findings of DMD in the 16 patients tested. Molecular genetic analysis showed dystrophin gene deletions in 11 of these 16 patients. Four and seven of the students stopped schooling and had learning difficulties, respectively; only nine had satisfactory school performances. Eight out of 14 patients evaluated were classified as having severe to total dependency levels on the modified Barthel Index for activities of daily living assessment. DMD is associated with significant medical and social needs for a developing country such as Malaysia. Earlier referral, genetic counselling, and provision of support and rehabilitative services are the main priorities.

Jamaiah I, Rohela M

Southeast Asian J. Trop. Med. Public Health, 2005 Jan;36(1):68-71.
PMID: 15906644

A total of 246 stool samples were collected from the public who participated in a Medical Fair held at the University Malaya Medical Center. The stools were examined for intestinal parasites using the formalin-ether concentration technique. The overall infection rate was 6.9% (17 out of 246), with Trichuris trichiura being the most common parasite (4.5%), followed by Ascaris lumbricoides (0.8%), Clonorchis sinensis (0.8%), hookworm (0.4%), and Entamoeba histolytica (0.4%). None of these participants showed any clinical symptoms. The highest infection rate was among the Chinese 7.7% (13 out of 169), followed by the Malays 7.0% (3 out of 43) and Indians 3.3% (1 out of 30). The highest infection rate was in the age group 16-30 years, which was 9% (6 out of 67). The two cases of clonorchiasis were from two Chinese women aged 28 and 66 years. The 28-year-old Chinese woman was born in Malaysia and had never left the country, while the older woman was also born in Malaysia but had visited Hong Kong as a tourist on two occasions. Both enjoyed eating raw fresh water fish with porridge.

Fulltext High blood pressure and associated cardiovascular risk factors in Iran: Isfahan Healthy Heart Programme

Sadeghi M, Roohafza HR, Kelishadi R

Med J Malaysia, 2004 Oct;59(4):460-7.
PMID: 15779578

This study was done to estimate the prevalence of high blood pressure (BP) in treated and non-treated subjects with respect to age and gender and its association with other cardiovascular risk factors in Iran. This cross sectional study was performed in three cities of Iran on participants over 19 years at 2002. First a questionnaire consisting of demographic details, drug intake and smoking status was filled. Then physical examination including systolic and diastolic blood pressure (SBP, DBP), body mass index (BMI) and waist to hip circumference (WHC) was performed. Fasting blood sample was drawn for sugar (FBS), total cholesterol (TC) and triglyceride (TG) and a 2-hour postprandial glucose was also measured. In this study performed on 12494 subjects, 48% were males and 52% females. The mean age of men and women was 38.99+/-15.30 and 38.80+/-14.54 years respectively. The prevalence of high BP in men and women was 15.6% and 18.8% respectively. The prevalence of high BP was higher in women than in men, except in the younger age classes. Overall 26.7% of hypertensive men and 47.7% of hypertensive women were on anti-hypertensive pharmacological treatment. Among the treated patients, BP was under control in 6.4% of the men and 13.8% of the women. In 86.5% of men with high BP and 89.3% of women with high BP, at least one other cardiovascular risk factor was present and its prevalence increased with age in both genders. BMI >25 (especially abdominal obesity) was the most frequent associated risk factor (41.9% in male, 59% in female). Except for smoking, the prevalence of each cardiovascular risk factor increased with the severity of hypertension, except in young women. The prevalence of high BP- even in treated subjects- is high in Iran. Many subjects with high BP have at least one other associated cardiovascular risk factor. These data emphasize the necessity of implementing community-based interventions.

Singapore Dent J, 2004 Dec;26(1):30-8.
PMID: 15736839

The aim of the present study was to determine the oral health status of 16-year-old Malaysian school children. The prevalence of caries was 75.5%. More than 60% of subjects had caries experience by teeth (DMFT) scores of 0-3. The largest component of the DMFT and caries experience by surface index was the filled component. Females had higher caries prevalence and caries scores than males. The mouth and tooth prevalences of enamel defects were 56% and 21.8%, respectively. The most common type of enamel defects observed were diffuse opacities, affecting 95.5% of affected subjects and 92.1% of affected teeth. One-third of subjects had healthy gingival conditions, 8.6% had bleeding gingivae, 55.1% had calculus and 3% had pockets. Less than 1% of subjects wore or required dentures. Cleft lip and/or palate was uncommon. This study shows that the prevalence of caries and DMFT scores have declined over the last 30 years.

PMID: 26373923 DOI: 10.1186/s13054-015-1055-x

Consensus criteria for pediatric severe sepsis have standardized enrollment for research studies. However, the extent to which critically ill children identified by consensus criteria reflect physician diagnosis of severe sepsis, which underlies external validity for pediatric sepsis research, is not known. We sought to determine the agreement between physician diagnosis and consensus criteria to identify pediatric patients with severe sepsis across a network of international pediatric intensive care units (PICUs).

Fulltext Prevalence and association of smokeless tobacco use with the development of periodontal pocket among adult males in Dawan Valley, Yemen: a cross-sectional study

Al-Tayar B, Tin-Oo MM, Sinor MZ, Alakhali MS

Tob Induc Dis, 2015;13:35.
PMID: 26539068 DOI: 10.1186/s12971-015-0061-8

BACKGROUND: The traditional type of smokeless tobacco used in the Arabian Peninsula, particularly common in Yemen, is called shammah. This study aims to determine the prevalence of shammah use and its association with the development of periodontal pockets. Other associated factors with the development of periodontal pocket were also determined.
METHODS: This cross-sectional study included 346 adult males aged 18 years old to 68 years old. Socio-demographic characteristics, oral hygiene practices, and shammah use history were surveyed by using a structured interview questionnaire. The clinical assessment for the presence or absence of periodontal pockets was assessed on the basis of community periodontal index. The chi-square test was used to assess significant differences in study groups in terms of the presence of periodontal pockets. Multivariable logistic regression was selected to assess potential associated factors with the development of periodontal pockets.
RESULTS: Among the 346 adult males, 248 (71.7 %), 30 (8.6 %), and 68 (19.7 %) males never used shammah, were former shammah users, and were current shammah users, respectively. The significant associated factors with the development of periodontal pocket were age group (30 years old and above) (Adjusted Odds Ratio (AOR) = 2.03, 95 % CI: 1.13, 3.65; P = 0.018), low family income category (AOR = 2.35, 95 % CI: 1.39, 3.99; P = 0.001), former shammah user (AOR = 2.66, 95 %: CI: 1.15, 6.15; P = 0.022), and current shammah user (AOR = 6.62, 95 %: CI: 3.59, 12.21; P = 0.001).
CONCLUSIONS: The results revealed that periodontal pockets were significantly associated with age group (30 years old and above), low family income category, former shammah use, and current shammah use. The findings of the current study highlighted the need to develop comprehensive shammah prevention programs and reduce periodontal disease and other shammah-associated diseases.

Fulltext Detection of Langat virus by TaqMan real-time one-step qRT-PCR method

Muhd Radzi SF, Rückert C, Sam SS, Teoh BT, Jee PF, Phoon WH, et al.

Sci Rep, 2015;5:14007.
PMID: 26360297 DOI: 10.1038/srep14007

Langat virus (LGTV), one of the members of the tick-borne encephalitis virus (TBEV) complex, was firstly isolated from Ixodes granulatus ticks in Malaysia. However, the prevalence of LGTV in ticks in the region remains unknown. Surveillance for LGTV is therefore important and thus a tool for specific detection of LGTV is needed. In the present study, we developed a real-time quantitative reverse-transcription-polymerase chain reaction (qRT-PCR) for rapid detection of LGTV. Our findings showed that the developed qRT-PCR could detect LGTV at a titre as low as 0.1 FFU/ml. The detection limit of the qRT-PCR assay at 95% probability was 0.28 FFU/ml as determined by probit analysis (p ≤ 0.05). Besides, the designed primers and probe did not amplify ORF of the E genes for some closely related and more pathogenic viruses including TBEV, Louping ill virus, Omsk hemorrhagic fever virus (OHFV), Alkhurma virus (ALKV), Kyasanur Forest Disease virus (KFDV) and Powassan virus (POWV) which showed the acceptable specificity of the developed assay. The sensitivity of the developed method also has been confirmed by determining the LGTV in infected tick cell line as well as LGTV- spiked tick tissues.

Fulltext Diverse and abundant multi-drug resistant E. coli in Matang mangrove estuaries, Malaysia

Ghaderpour A, Ho WS, Chew LL, Bong CW, Chong VC, Thong KL, et al.

Front Microbiol, 2015;6:977.
PMID: 26483759 DOI: 10.3389/fmicb.2015.00977

E.coli, an important vector distributing antimicrobial resistance in the environment, was found to be multi-drug resistant, abundant, and genetically diverse in the Matang mangrove estuaries, Malaysia. One-third (34%) of the estuarine E. coli was multi-drug resistant. The highest antibiotic resistance prevalence was observed for aminoglycosides (83%) and beta-lactams (37%). Phylogenetic groups A and B1, being the most predominant E. coli, demonstrated the highest antibiotic resistant level and prevalence of integrons (integron I, 21%; integron II, 3%). Detection of phylogenetic group B23 downstream of fishing villages indicates human fecal contamination as a source of E. coli pollution. Enteroaggregative E. coli (1%) were also detected immediately downstream of the fishing village. The results indicated multi-drug resistance among E. coli circulating in Matang estuaries, which could be reflective of anthropogenic activities and aggravated by bacterial and antibiotic discharges from village lack of a sewerage system, aquaculture farms and upstream animal husbandry.
