    Eur Arch Otorhinolaryngol, 2012 Mar;269(3):999-1004.
    PMID: 21789676 DOI: 10.1007/s00405-011-1712-x
    Early detection of oral potentially malignant epithelial lesions (PMELs) is aimed at improving survival rates as carcinogenesis is a multistep process and prevention is possible if these lesions are detected at an early and reversible stage of the disease. A prospective clinical study aimed at determining the prevalence of bilateral 'mirror-image' oral PMELs was carried out. Sample consisted of 32 (53.3%) Indians, 23 (38.3%) Chinese, 4 (6.7%) Malays and one (1.7%) Nepalese. All had histopathological confirmation of their primary existing PMEL as inclusion criteria. A total of 70 primary lesions were detected. The most common PMEL found was oral lichen planus. Of these, 28 (46.7%) patients exhibited bilateral 'mirror-image' lesions (n = 42) either synchronously (n = 32/42) or metachronously (n = 10/42). The remaining 32 (53.3%) patients had normal-looking contralateral mucosa. Present findings suggest that patients presenting with oral PMELs are at greater risk of developing a second lesion, most probably in the contralateral 'mirror-image' site.

    PMID: 21420589 DOI: 10.1016/j.jcrs.2010.10.050
    PURPOSE: To determine the prevalence of and risk factors for AcriFlex 50CSE hydrophilic acrylic intraocular lens (IOL) opacification approximately 3 years after implantation.
    SETTING: Selayang Hospital, Selangor, Malaysia.
    DESIGN: Cross-sectional study.
    METHODS: Patients who had AcriFlex 50CSE IOL implantation in 2005 and 2006 were identified from operating logbooks and recalled via telephone and letters. Opaque IOLs were explanted and sent for scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS).
    RESULTS: The review showed that 18 patients had died and 67 had declined examination or could not be contacted, leaving 239 eyes for evaluation. The age of the patients ranged from 25 to 85 years. Of the patients, 83 (34.7%) were Malay, 127 (53.1%) Chinese, and 29 (12.1%) East Indian. The male:female ratio was 1:1. Fourteen eyes of 13 patients (5.4%) had IOL opacification; 1 had bilateral opacification. Five eyes had fine deposits, and 9 eyes had dense opaque deposits. Seven opaque IOLs required explantation. There was no correlation between age (P=.645), sex (P=.319), or race (P=.860) and IOL opacification. Pearson chi-square analysis showed a strong association between diabetes mellitus and IOL opacification (P=.019). Nine (69.2%) of the 13 patients with opacification had diabetes. Scanning electron microscopy and EDS showed calcium and phosphate deposits on the optic surface and intralenticularly near the anterior surface of the optic.
    CONCLUSIONS: Results indicate that diabetes mellitus is a risk factor for AcriFlex hydrophilic acrylic IOL opacification. In some cases, opacification affected vision, necessitating explantation. The pathophysiology of this complication is unknown.

    PMID: 21939163 MyJurnal
    This study describes the prevalence of selected cardiovascular disease (CVD) risk factors screened in patients 30 years and above attending a health centre in Cheras, Selangor. The study involved 3772 patients screened from March 2002 to June 2008. Risk factors screened included blood pressure, height, weight, serum total cholesterol, random blood sugar levels and smoking status. Majority of respondents were between 40 and 49 years of age (58.1%), males (64.7%) and ethnic Malays (74.4%). About two thirds (62.6%) were found to be overweight or obese, two fifths (40.2%) had hypercholesterolemia, a third (34.2%) had hypertension and 31.6% were smokers at some time. Overall 87% and 60% had at least one and two CVD risk factors respectively. Prevalence of four of the five risk factors screened was highest among the Malay middle aged men and lowest among the Chinese. Thus a substantial proportion of middle aged men were at high risk of CVD. Our findings show the need for ongoing monitoring of CVD risk factors and implementation of effective preventive strategies.

    Sasidharan S, Lachumy SJ, Ravichandran M, Latha LY, Gegu SR
    Asian Pac J Trop Med, 2011 Jan;4(1):72-5.
    PMID: 21771421 DOI: 10.1016/S1995-7645(11)60037-0
    OBJECTIVE: To study the epidemiology of Helicobacter pylori (H. pylori) infection according to age group.

    METHODS: H. pylori infection data among 1 965 consecutive patients referred to the Endoscopy Unit collected at Sungai Petani Hospital for oesophagogastro-duodenoscopy (OGD). The patients were divided into 9 age groups (10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89 and 90-99 years). In addition these groups were further divided into three minor group namely young adults (10-39), older adults (40-69) and geriatric groups (70-99).

    RESULTS: Overall prevalence of infection of H. pylori was analyzed and found that the prevalence increase with age (P<0.05). When the patients divided by ethnic and gender group with age, prevalence rate among young adults and older adults significantly higher (P<0.05) compared to geriatric groups across all races and gender (P<0.05). Furthermore, significantly higher number of males were infected compared to female (P<0.05) but such trend was only observed among older adult groups. In addition, there is a significant differences in H. pylori infection prevalence rates among ethnic groups (highest in Indians adults, followed Chinese and low in Malays, P<0.05).

    CONCLUSIONS: The overall prevalence of H. pylori did increase with age group across ethnicity and gender, in Northern Peninsular Malaysia.

    PMID: 21488476
    Abdominal obesity (AO), measured by waist circumference (WC), is a stronger predictor of subsequent development of cardiovascular disease (CVD) than generalised obesity, which is measured by body mass index (BMI). This study aimed to measure WC and prevalence of AO in Malaysians visiting primary care physicians. 1893 patients between the ages of 18 and 80 attending primary care clinics in Malaysia were recruited over two days for this multi-centre cross-sectional study. Pregnant women were excluded, their medical history, weight, height and WC were examined. The prevalence of co-morbidities were as follows: (1) CVD-4%, lipid disorder-17%, hypertension-26%, diabetes-14% and any of the clinical characteristics of CVD/lipid disorder/hypertension/diabetes-38%. The mean BMI for men and women was 25.62 +/- 4.73 kg/m2 and 26.63 +/- 5.72 kg/m2, respectively. Based on WHO criteria for BMI (overweight, 25-29.9 kg/m2; obese, > 30 kg/m2), 34.2% were overweight and 20.4% were obese. The mean WC for men and women was 89.03 +/- 13.45 cm and 84.26 +/- 12.78 cm, respectively. Overall, 55.6% had AO and there was higher prevalence among women (based on International Diabetes Federation criteria: WC > or = 90 cm for men and > or = 80 cm for women). AO was present in approximately 71% patients with lipid disorder, in 76% with hypertension and in 75% with diabetes. Patients with AO were also at a higher risk of developing co-morbidities. Malaysia has a high prevalence of AO and associated cardiovascular risk factors. This needs to be addressed by public health programs, which should also include routine measurement of WC.

  7. Prevalence, antibiotic resistance and RAPD typing of Campylobacter species isolated from ducks, their rearing and processing environments in Penang, Malaysia
    Adzitey F, Rusul G, Huda N, Cogan T, Corry J
    Int J Food Microbiol, 2012 Mar 15;154(3):197-205.
    PMID: 22285201 DOI: 10.1016/j.ijfoodmicro.2012.01.006
    We report for the first time on the prevalence, antibiotic resistance and RAPD types of Campylobacter species in ducks and duck related environmental samples in Malaysia. Samples were examined by enrichment in Bolton Broth followed by plating onto modified Charcoal Cefoperazone Deoxycholate agar (mCCDA) and/or plating directly onto mCCDA. A total of 643 samples were screened, and the prevalence of Campylobacter spp. in samples from different sources ranged from 0% to 85%. The method of isolation had a significant (P<0.05) effect on the isolation rate. One hundred and sixteen Campylobacter isolates, comprising of 94 Campylobacter jejuni, 19 Campylobacter coli and three Campylobacter lari, were examined for their sensitivity to 13 antibiotics. Majority of the C. jejuni isolates were resistant to cephalothin (99%), tetracycline (96%), suphamethoxazole/trimethoprim (96%), and very few were resistant to gentamicin (5%), chloramphenicol (7%) and erythromycin (1%). All C. coli isolates were resistant to cephalothin, nalidixic acid, norfloxacin and tetracycline but susceptible to chloramphenicol, erythromycin and gentamicin. The three C. lari isolates were resistant to all the antibiotics tested except chloramphenicol and gentamicin (1/3 and 2/3 susceptible, respectively). Genetic diversity of Campylobacter isolates were determined using random amplification of polymorphic DNA (RAPD). C. jejuni and C. coli isolates belong to fifty-eight and twelve RAPD types, respectively.

    PMID: 21802305 DOI: 10.1016/j.jocn.2010.12.054
    Recent studies associated the HLA-B 1502 allele with carbamazepine (CBZ)-induced Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) in patients from China, Thailand and Malaysia. No association has been found in patients from Europe or Japan. Linkage summary reports from East and South-east Asia predict a highly significant odds ratio (OR) of 84.75 (95% confidence interval [CI]=42.53-168.91; p=8.96×10[-15]) with sensitivity and negative predictive values of 92% and 98%, respectively. The higher prevalence of HLA-B 1502 allele among certain Asian populations (10-15%) compared to Caucasians (1-2%) may explain a 10-fold to 25-fold higher incidence of CBZ-SJS/TEN in patients from Asia. Screening for HLA-B 1502 before using CBZ can prevent SJS/TEN in certain populations, but screening may be less beneficial in populations with low HLA-B 1502 allele frequency and in patients exposed to CBZ for more than 2 months. A retrospective study demonstrated that the costs of HLA-B 1502 screening were less than those of SJS treatment. This article reviews possible benefits and concerns of HLA-B 1502 screening in clinical practice.

    Tang WS, Khoo EM
    J Sex Med, 2011 Jul;8(7):2071-8.
    PMID: 21492404 DOI: 10.1111/j.1743-6109.2011.02280.x
    INTRODUCTION: Premature ejaculation (PE) is common. However, it has been underreported and undertreated.
    AIMS: To determine the prevalence of PE and to investigate possible associated factors of PE.
    METHODS: This cross-sectional study was conducted at a primary care clinic over a 3-month period in 2008. Men aged 18-70 years attending the clinic were recruited, and they completed self-administered questionnaires that included the Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function, sociodemography, lifestyle, and medical illness. The operational definition of PE included PE and probable PE based on the PEDT.
    MAIN OUTCOME MEASURE: Prevalence of PE.
    RESULTS: A total of 207 men were recruited with a response rate of 93.2%. There were 97 (46.9%) Malay, 57 (27.5%) Chinese, and 53 (25.6%) Indian, and their mean age was 46.0 ± 12.7 years. The prevalence of PE was 40.6% (N = 82) (PE: 20.3%, probable PE: 20.3% using PEDT). A significant association was found between ethnicity and PE (Indian 49.1%, Malay 45.4%, and Chinese 24.6%; χ(2) = 8.564, d.f. = 2, P = 0.014). No significant association was found between age and PE. Multivariate analysis showed that erectile dysfunction (adjusted odds ratio [OR] 4.907, 95% confidence interval [CI] 2.271, 10.604), circumcision (adjusted OR 4.881, 95% CI 2.346, 10.153), sexual intercourse ≤5 times in 4 weeks (adjusted OR 3.733, 95% CI 1.847, 7.544), and Indian ethnicity (adjusted OR 3.323, 95% CI 1.489, 7.417) were predictors of PE.
    CONCLUSION: PE might be frequent in men attending primary care clinics. We found that erectile dysfunction, circumcision, Indian ethnicity, and frequency of sexual intercourse of ≤5 times per month were associated with PE. These associations need further confirmation.

    PMID: 21498788 DOI: 10.2337/dc11-0005
    OBJECTIVE:
    To determine the prevalence of prediabetes and diabetes among rural and urban Malaysians.
    RESEARCH DESIGN AND METHODS:
    This cross-sectional survey was conducted among 3,879 Malaysian adults (1,335 men and 2,544 women). All subjects underwent the 75-g oral glucose tolerance test (OGTT).
    RESULTS:
    The overall prevalence of prediabetes was 22.1% (30.2% in men and 69.8% in women). Isolated impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) were found in 3.4 and 16.1% of the study population, respectively, whereas 2.6% of the subjects had both IFG and IGT. Based on an OGTT, the prevalence of newly diagnosed type 2 diabetes was 12.6% (31.0% in men and 69.0% in women). The prediabetic subjects also had an increased prevalence of cardiovascular disease risk factors.
    CONCLUSIONS:
    The large proportion of undiagnosed cases of prediabetes and diabetes reflects the lack of public awareness of the disease.

    PMID: 21921304
    Objectives: To determine the relationship between major depressive disorder, anxiety disorders and the quality of life of haematological cancer patients.
    Methods: This cross-sectional study was conducted at Ampang Hospital Kuala Lumpur, Malaysia, a tertiary referral centre hospital for haematological cancer. The Mini-International Neuropsychiatric Interview was used for the diagnosis of major depressive disorder and anxiety disorders. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire was utilised to measure patients’ quality of life.
    Results: A total of 105 haematological cancer patients were included in the study with response rate of 100%. Major depressive disorder correlated with almost all domains of the quality of life, except the pain scores. Logistic regression showed that insomnia and financial difficulties were related to major depressive disorder. Different anxiety disorders also correlated with quality of life in specific domains. The leading anxiety disorders that correlated mostly with quality of life scales were generalised anxiety disorder, followed by obsessive-compulsive disorder, social anxiety disorder, as well as post-traumatic stress disorder and panic disorder with agoraphobia (p < 0.05).
    Conclusions: Psychological treatment along with medication and intervention should be implemented to
    improve the overall quality of life and psychiatric disorder symptoms among the haematological cancer
    patients.

    Dyspepsia is perhaps the most common gastrointestinal disease universally. The prevalence of dyspepsia ranges from 7-40% in population based studies worldwide. These figures vary with definition of dyspepsia used and also with the survey methodology. As with Western studies, functional dyspepsia (FD) predominates in Asia. With a decline in peptic ulcer disease and gastric cancer, the proportion of FD is set to increase further. Studies have shown FD to account for 50-70% of cases of uninvestigated dyspepsia. In Malaysia dyspepsia has been reported in up to 15% of a rural and 25% of an urban population. No racial differences were seen in the rural survey. In the urban survey, Malays and Indians were found to have significantly more dyspepsia than Chinese. No clear explanation can be found for these racial differences. In clinical practice, Malays seem to complain a lot of wind and bloating in the "stomach." This is interesting to note when you compare it with the prevalence of H. pylori which is distinctly less common amongst Malays compared to the Indians and Chinese. As with many Asian populations, many Malaysians do not consult for complains of dyspepsia. Many will self medicate and others may even bear with their complains. This is probably true in the rural population. Traditional medications are often used and these are often ethnic based. Different types of lotions for example are used for massaging the putative area in the abdomen by Malay, Chinese and Indian patients. Moxibustion and acupuncture is still practiced by Chinese traditional physicians for treatment of dyspepsia. The notion that mood disorders may underlies dyspepsia is still poorly accepted by a less educated or rural population who consider a psychiatric consultation a taboo. Amongst urban dwellers where Westernized medical care is readily available and the awareness of potential serious disease like cancer is higher, consultation for dyspepsia is certainly higher. Indeed a higher education level has been identified as independent risk factors for dyspepsia in both an urban and rural population survey in Malaysia. With greater consultation for dyspepsia, there has also been a higher demand and utilization of endoscopy services for investigation of gastrointestinal diseases in the country.

  17. Anxiety, depression and quality of life differences between functional and organic dyspepsia
    Mahadeva S, Goh KL
    J Gastroenterol Hepatol, 2011 Apr;26 Suppl 3:49-52.
    PMID: 21443710 DOI: 10.1111/j.1440-1746.2011.06656.x
    OBJECTIVE AND BACKGROUND:
    The role of psychological disturbance in the pathogenesis of functional dyspepsia is uncertain. We aimed to examine for differences in anxiety, depression and health-related quality of life (HRQOL) between adults with organic (OD) and functional dyspepsia (FD).

    METHODOLOGY:
    A prospective, cross-sectional study of Malaysian adults undergoing oesophago-gastro-duodenoscopy (OGDS) for the primary indication of dyspepsia was conducted. Prior to OGDS, locally translated and validated versions of the Hospital Anxiety and Depression Scale (HADS), Nepean Dyspepsia Index (NDI) and Leeds Dyspepsia Questionnaire (LDQ) were administered.

    RESULTS:
    839 patients (mean age 49.6 ± 15.8 years, 55.7% female, ethnic division: Malays 30.5% , Chinese 38.4%, Indians 29.4%) were studied between June 2008 and March 2009. 472 (56.3%) and 367 (43.7%) patients had FD and OD respectively. There was no difference in the mean LDQ score between FD and OD patients (18.6 vs 18.1, P = 0.4). Moderate/severe anxiety was more prevalent in FD compared to OD patients (28.5% vs 23.1%, P = 0.05) but there was no significant difference in depression. Summary scores for the NDI revealed a lower mean value in FD patients compared to OD patients (68.6 ± 19.5 vs 71.4 ± 19.6, P = 0.04).

    CONCLUSION:
    Patients with FD have a lower HRQOL compared to those with OD, but this could not be attributed to differences in anxiety nor depression between both groups.

  18. Spraguea (Microsporida: Spraguidae) infections in the nervous system of the Japanese anglerfish, Lophius litulon (Jordan), with comments on transmission routes and host pathology

    PMID: 21545438 DOI: 10.1111/j.1365-2761.2011.01255.x
    Anglerfish from the genus Lophius are a globally important commercial fishery. The microsporidian Spraguea infects the nervous system of these fish resulting in the formation of large, visible parasitic xenomas. Lophius litulon from Japan were investigated to evaluate the intensity and distribution of Spraguea xenomas throughout the nervous system and to assess pathogenicity to the host and possible transmission routes of the parasite. Spraguea infections in L. litulon had a high prevalence; all fish over 403 mm in standard length being infected, with larger fish usually more heavily infected than smaller fish. Seventy percent of all fish examined had some gross visible sign of infection. The initial site of development is the supramedullary cells on the dorsal surface of the medulla oblongata, where all infected fish have parasitic xenomas. As the disease progresses, a number of secondary sites typically become infected such as the spinal, trigeminal and vagus nerves. Fish with infection in the vagus nerve bundles often have simultaneous sites of infection, in particular the spinal nerves and along the ventral nerve towards the urinary bladder. Advanced vagus nerve infections sometimes form xenomas adjacent to kidney tissue. Spraguea DNA was amplified from the contents of the urinary bladders of two fish, suggesting that microsporidian spores may be excreted in the urine. We conclude that supramedullary cells on the hindbrain are the primary site of infection, which is probably initiated at the cutaneous mucous glands where supramedullary cells are known to extend their peripheral axons. The prevalence of Spraguea infections in L. litulon was very high, and infections often extremely heavy; however, no associated pathogenicity was observed, and heavily infected fish were otherwise normal.

  19. Do the prevalence and components of metabolic syndrome differ among different ethnic groups? A cross-sectional study among obese Malaysian adolescents
    Narayanan P, Meng OL, Mahanim O
    Metab Syndr Relat Disord, 2011 Oct;9(5):389-95.
    PMID: 21718129 DOI: 10.1089/met.2011.0014
    OBJECTIVE: The aim of this study was to determine the prevalence of metabolic syndrome and the most common combination of cardiometabolic disorders among different ethnic groups of obese adolescents in Malaysia.
    RESEARCH DESIGN AND METHODS: A cross-sectional study among 335 obese adolescent boys and girls aged 12-18 years from 10 randomly selected schools was conducted. After recording blood pressure and waist circumference (WC), a fasting blood sample was obtained and analyzed for glucose and lipids. Metabolic syndrome was diagnosed on the basis of adolescent metabolic syndrome criteria specified by National Cholesterol Education Program Adult Treatment Panel III if three of the five risk factors--hypertriglyceridemia, hyperglycemia, hypertension, low high-density lipoprotein C, and increased WC--were present. The prevalence among different ethnic groups was analyzed.
    RESULTS: The obesity rate among adolescents was 8.4%, and nearly one-third of the obese adolescents had metabolic syndrome. More than 90% of obese adolescents had at least one metabolic abnormality. Metabolic syndrome was more prevalent among obese boys (40.2%) compared to obese girls (17%). Boys had significantly higher mean WC and triglycerides and lower HDL-C (P value 0.0001). Increased WC and triglycerides and high blood pressure comprised the most prevalent (34.3%) risk factor combination followed by WC, low HDL, and high blood pressure (22.5%). Over all, Indians had the highest prevalence of metabolic syndrome (36.4%), followed by Chinese (33.8%) and Malays (27.4%). Elevated triglyceride levels were more prevalent among Chinese, hypertension among Malays, and the other three abnormalities among Indians.
    CONCLUSION: Indians had the highest prevalence of metabolic syndrome. Increased WC and triglycerides and high blood pressure comprised the most prevalent risk factor combination.

    This comparative cross-sectional study was conducted in the pediatric daycare unit, Hospital Universiti Sains Malaysia to determine the prevalence of craniofacial deformities (CFD) and the association between these deformities and different clinical presentations among thalassemia patients. Patients were classified as either craniofacial deformity positive (CFD+) or craniofacial deformity negative (CFD-) by two examiners based on the presence or absence of deformity of the cheeks, frontal and/or maxillary bones. Fifteen clinical parameters were compared between the groups. Nineteen out of 43 patients (44.2%; confidence interval, 30.2-58.2%) had craniofacial deformities (CFD+). Both groups were comparable among the clinical parameters studied. Patients in the CFD+ group did not start their blood transfusions significantly earlier than the CFD- group (p = 0.50) and had a nonsignificantly lower mean pretransfusion hemoglobin level than the CFD- group (p = 0.71). Patients receiving regular monthly blood transfusions had a nonsignificantly smaller percentage of CFD than those transfused less often (p = 0.495). CFD+ patients had a splenectomy at a nonsignificantly younger age than CFD- patients (p = 0.36). HbE/beta thalassemia patients were not significantly less likely to develop CFD than other varieties (p = 0.50) and males had a nonsignificantly higher percentage of CFD than females (p = 0.29). This study shows CFD in thalassemia patients are still prevalent but no significant associated factors were found; however, a nonsignificantly higher prevalence of CFD was observed in patients with signs of severe disease and less efficient treatment.
