Oral mucosal lesions in non oral habit diabetic patients and association of diabetes mellitus with oral precancerous lesions

Saini R, Al-Maweri SA, Saini D, Ismail NM, Ismail AR

Diabetes Res Clin Pract, 2010 Sep;89(3):320-6.
PMID: 20488573 DOI: 10.1016/j.diabres.2010.04.016

AIMS: This study was aimed to determine the prevalence of oral mucosal lesions (OML) in patients with diabetes mellitus (DM) and non-diabetic subjects without any oral habits and to investigate the association of DM with oral precancerous lesions.
METHODS: This cross-sectional study involved 420 diabetic and 420 non-diabetic control subjects without any oral habits. Detailed oral examination was performed based on international criteria.
RESULTS: A significantly greater proportion of subjects with DM (45%) had one or more OML in comparison to non-diabetics (38.3%). Patients with DM showed a significantly greater prevalence of geographic tongue, denture stomatitis and angular cheilitis than non-diabetics (p<0.05). The results also showed an association between occurrence of one or more OML and metabolic control of diabetic patients (p<0.05). For precancerous lesions, lichen planus was found in two diabetic patients while none of controls had any precancerous lesion (p>0.05).
CONCLUSIONS: Prevalence of OML was significantly higher in diabetic patients than non-diabetics and this prevalence was associated with the metabolic control of the patients. However, no association was observed between DM and oral precancerous lesions.

Legislating separation and solidarity in plural societies: the Chinese in Indonesia and Malaysia

Hwang JC, Sadiq K

Nationalism Ethn Polit, 2010;16(2):192-215.
PMID: 20648997 DOI: 10.1080/13537113.2010.490757

The Chinese minority plays a dominant role in the economies of Indonesia and Malaysia, a fact that evokes indigenous resentment. However, Indonesia and Malaysia dealt differently with the issue. Malaysia legislated the Malays into the economy and protected Chinese citizenship, making them an integral part of a multicultural state. By contrast, New Order Indonesia adopted policies of economic manipulation, forced assimilation, and unequal citizenship. Only when the New Order regime fell did Chinese integration begin. The policy trajectories of Indonesia and Malaysia offer important lessons for plural states.

Vulnerability, life events and depression amongst Moslem Malaysian women: comparing those married and those divorced or separated

Abdul Kadir NB, Bifulco A

Soc Psychiatry Psychiatr Epidemiol, 2011 Sep;46(9):853-62.
PMID: 20556355 DOI: 10.1007/s00127-010-0249-4

INTRODUCTION: The experiences of married and single mothers were compared in an investigation of psychosocial vulnerability, stress and depression in a community-based study of Moslem mothers in Malaysia. For the first time, a model of vulnerability-provoking agent originally developed by Brown et al. in the UK was tested in a Malaysian context.
METHODS: A cross-sectional study was carried out in the district of Johor Bahru, Malaysia. Of the 1,200 women approached from membership of community associations, 1,002 (84%) completed the questionnaires. Severe life events Recent Life Events Questionnaire (Brugha and Cragg in Acta Psychiatr Scand 82:77-81, 1990) and psychosocial vulnerability (VDQ) (Moran et al. in Br J Clin Psychol 40:411-427, 2001) were used to measure vulnerability factors. Depression was measured by the General Health Questionnaire (GHQ-30) (Havenaar et al. in Soc Psychiatry Psychiatr Epidemiol 43:209-215, 2008).
RESULTS: Single mothers had significantly higher rates of depression than those married (60.5 vs. 39.5%), as well as higher rates of severe life events and Negative Elements in Close Relationships (lack of support and conflict with children). However, married mothers had greater Negative Evaluation of Self. The two vulnerability factors were correlated to each other and to severe life events and social adversity. Logistic regression showed an interaction between severe life events in the material and relationship domains and joint vulnerability for depression outcome. The results are discussed in relation to the low recognition of psychosocial risks for depression in single mothers in Malaysia, as well as lack of appropriate services.

PMID: 19852326 MyJurnal

This paper seeks to determine the client's compliance level towards Methadone Maintenance Therapy (MMT) and identify its associated factors. A cross sectional study was conducted from June to September 2007 where 288 samples were interviewed. The outcomes were divided into good compliance and partial compliance categories. Overall client's compliance level is good at 86.1%. There are significant difference between mean age of groups (t = -2.041, p = 0.04); and significant associations of job's status (chi2 = 9.54, p = 0.008); client's confident score (t = -3.12, p = 0.023), client'ssocial function score (t = -2.308, p = 0.002) and client's social function level (chi2 = 5.43, p = 0.02) with compliance toward program. With multivariate analysis, only client's age, client's confidence score and client's job status were related to compliance status. It was concluded that there is high compliance rate among client's who received the program. Younger clients, low scores on client's confident and social function, and clients with unsteady jobs are at risk not to comply with treatment.

Swami V

Int J Psychol, 2009 Aug;44(4):266-73.
PMID: 22029555 DOI: 10.1080/00207590801888745

The process of cross-cultural migration may be particularly difficult for students travelling overseas for further or higher education, especially where qualitative differences exist between the home and host nations. The present study examined the sociocultural adjustment of sojourning Malaysian students in Britain. Eighty-one Malay and 110 Chinese students enrolled in various courses answered a self-report questionnaire that examined various aspects of sociocultural adjustment. A series of one-way analyses of variance showed that Malay participants experienced poorer sociocultural adjustment in comparison with their Chinese counterparts. They were also less likely than Chinese students to have contact with co-nationals and host nationals, more likely to perceive their actual experience in Britain as worse than they had expected, and more likely to perceive greater cultural distance and greater discrimination. The results of regression analyses showed that, for Malay participants, perceived discrimination accounted for the greatest proportion of variance in sociocultural adjustment (73%), followed by English language proficiency (10%) and contact with host nationals (4%). For Chinese participants, English language proficiency was the strongest predictor of sociocultural adjustment (54%), followed by expectations of life in Britain (18%) and contact with host nationals (3%). By contrast, participants' sex, age, and length of residence failed to emerge as significant predictors for either ethnic group. Possible explanations for this pattern of findings are discussed, including the effects of Islamophobia on Malay-Muslims in Britain, possible socioeconomic differences between Malay and Chinese students, and personality differences between the two ethnic groups. The results are further discussed in relation to practical steps that can be taken to improve the sociocultural adjustment of sojourning students in Britain.

Fulltext Classical varicose vein surgery in a diverse ethnic community

Murli NL, Navin ID

Med J Malaysia, 2008 Aug;63(3):193-8.
PMID: 19248688 MyJurnal

Chronic venous disorders range from telangiactasia or spider veins to varicose veins, venous swellings, skin changes and venous ulcerations. The aim of this study is to assess outcome of varicose vein surgery in the ethnically diverse population of Penang, Malaysia. This study is a retrospective analysis of patients seen from 1999 to 2004. All patients who presented to the outpatient clinic of our surgical department with saphenofemoral junction (SFJ) and/or saphenopopliteal junction (SPJ) reflux associated with incompetence of the great saphenous vein (GSV) or small saphenous vein (SSV) respectively underwent classical varicose varicose vein surgery. A single surgeon at a single institution performed the surgeries. Data from pre-operative, post-operative and follow-up procedures were recorded in case report forms. A total of 202 cases were treated. Of these, 200 were qualified by the inclusion criteria and follow-ups, with 23 who were treated bilaterally. Of those treated, Chinese comprised 47.5%, Indians 27.0%, Malays 12.5% and foreigners 13.0% (largely Indonesian Chinese, British and Americans). The average age was 52.1 years. Indians had the highest average BMI of 29.2, compared to the Chinese who had the lowest of 24.6. Based on occupation, housewives (43.0%), blue collar workers (19.0%), salespersons (12.0%) and factory workers (9.5%) were among those afflicted with varicose veins. While local Chinese predominated in the business groups (salespersons and food-related workers), the Indians and Malays in this study were mainly factory workers and/or blue collar workers. Symptomatology in descending order of severity included pain in 80.0% of cases, swelling in 65.5%, heaviness in 53.5%, cramps in 53.0%, lipodermatosclerosis in 39.0%, superficial thrombophlebitis in 33.5%, venous ulceration in 32.0%, eczema 22.0% and cellulitis in 12.5% of patients. Post surgery pains dropped to 9.9%, cramps 6.4%, heaviness 5.5% and swelling 5.3% (p<0.0001 in all groups). Indians had the highest rate of venous ulcers (35.2% of all Indians treated) possibly due to their high BMI and low socioeconomic background. In cases of venous ulcers, gram negative infections (49.8%) were more common than gram positive infections at 18.8%. Operative procedures performed included great saphenous vein high ligation in 96.5% of cases, stripping 93.5% and multiple avulsions in 98.5%, saphenous popliteal junction ligation with multiple avulsions in 13.0% and subfascial ligation in 10.5%. Operative complications included induration (40.0% of cases), bruising in 49.5%, pains in 15.0%, paraesthesia in 3.5%, wound infection in 4.0%, deep venous thrombosis in 3.0% and ulcer recurrence in 7.5%. A total of 96.2% of patients treated expressed satisfaction with varicose vein surgery. Late presentations of chronic venous insufficiency, possibly as a result of poor understanding and inadequate education on diet, weight control, use of stockings and change in lifestyle by patients, employers and general practitioners are probably the cause of high rates of severe chronic venous disease especially venous ulcerations in the local community. However, classical varicose vein surgery is widely applicable across diverse ethnicities with a high rate of success.

Genetic variations of the ABCC2 gene in the Chinese, Malay, and Indian populations of Singapore

Ho WF, Koo SH, Yee JY, Lee JD

Drug Metab. Pharmacokinet., 2008;23(5):385-91.
PMID: 18974617

MRP2 is a drug transporter that is responsible for the gastrointestinal absorption and biliary excretion of a wide variety of endogenous and xenobiotic compounds, including many clinically used drugs. This study aims to identify genetic variations of ABCC2 gene in three distinct ethnic groups of the Singaporean population (n = 288). The coding region of the gene encoding the transporter protein was screened for genetic variations in the study population by denaturing high-performance liquid chromatography and DNA sequencing. Twenty-two genetic variations of ABCC2, including 8 novel ones, were found: 1 in the 5' untranslated region, 10 in the coding exons (8 nonsynonymous and 2 synonymous variations), and 11 in the introns. Three novel nonsynonymous variations: 2686G > A (Glu896Lys), 4240C > T (His1414Tyr) and 4568A > C (Gln1523Pro) were detected in single heterozygous Malay, Chinese, and Indian subjects, respectively. Among the novel nonsynonymous variations, 4240C > T and 4568A > C were predicted to be functionally significant. These data would provide fundamental and useful information for pharmacogenetic studies on drugs that are substrates of MRP2 in Asians.

Prevalence and risk factors for obstructive sleep apnea in a multiethnic population of patients presenting for bariatric surgery in Singapore

Lee YH, Johan A, Wong KK, Edwards N, Sullivan C

Sleep Med, 2009 Feb;10(2):226-32.
PMID: 18387341 DOI: 10.1016/j.sleep.2008.01.005

INTRODUCTION: Obesity is becoming more prevalent world wide. Bariatric surgery is one treatment option for patients with severe or morbid obesity. There have been few comprehensive studies examining prevalence and risk factors for obstructive sleep apnea (OSA) in the multiracial Singaporean bariatric surgery population.
METHODS: We performed full polysomnography on 176 consecutive patients undergoing assessment for bariatric surgery. Questionnaires regarding snoring, the presence of witnessed apneas and the Epworth Sleepiness Scale (ESS) were administered. Anthropometric and demographic measurements include age, sex, race, body mass index (BMI) and neck circumference.
RESULTS: The prevalence of OSA was 72%, and 49% of the 176 patients had an AHI >= 15. There was a male predominance of OSA (X(2) = 29.7; p<0.001). OSA subjects had larger neck circumference (43.9 +/- 4.5 vs. 39.4 cm +/- 3.3; p<0.001) and higher BMI (43.1 +/- 7.6 vs. 39.1 +/- 5.4 kg/m(2); p<0.001). The neck circumference (OR = 1.37; p<0.001), presence of snoring (OR = 8.25; p<0.001) and an ESS >10 (OR = 3.24; p = 0.03) were significant independent predictors of an AHI >= 15. A neck circumference of 43 cm had an 80% sensitivity and 83% specificity for predicting an AHI >= 15.
CONCLUSIONS: OSA is common amongst Singaporeans undergoing evaluation for bariatric surgery, with a high prevalence of moderate and severe disease. An increased neck circumference is a strong independent predictor for an AHI >= 15, with a neck circumference of greater than 43 cm being a sensitive and specific predictor. Race was not found to be a risk factor.

Genetic variations of the SLCO1B1 gene in the Chinese, Malay and Indian populations of Singapore

Ho WF, Koo SH, Yee JY, Lee EJ

Drug Metab. Pharmacokinet., 2008;23(6):476-82.
PMID: 19122343

OATP1B1 is a liver-specific transporter that mediates the uptake of various endogenous and exogenous compounds including many clinically used drugs from blood into hepatocytes. This study aims to identify genetic variations of SLCO1B1 gene in three distinct ethnic groups of the Singaporean population (n=288). The coding region of the gene encoding the transporter protein was screened for genetic variations in the study population by denaturing high-performance liquid chromatography and DNA sequencing. Twenty-five genetic variations of SLCO1B1, including 10 novel ones, were found: 13 in the coding exons (9 nonsynonymous and 4 synonymous variations), 6 in the introns, and 6 in the 3' untranslated region. Four novel nonsynonymous variations: 633A>G (Ile211Met), 875C>T (Ala292Val), 1837T>C (Cys613Arg), and 1877T>A (Leu626Stop) were detected as heterozygotes. Among the novel nonsynonymous variations, 633A>G, 1837T>C, and 1877T>A were predicted to be functionally significant. These data would provide fundamental and useful information for pharmacogenetic studies on drugs that are substrates of OATP1B1 in Asians.

Fulltext Self-monitoring of blood glucose among diabetes patients attending government health clinics

Mastura I, Mimi O, Piterman L, Teng CL, Wijesinha S

Med J Malaysia, 2007 Jun;62(2):147-51.
PMID: 18705449 MyJurnal

The aims of this study were (i) to determine the prevalence of self-monitoring of blood glucose (SMBG) among Type 2 diabetes patients attending government health clinics and (ii) to ascertain the factors influencing SMBG. Five hundred and fifty-six Type 2 diabetes patients from two government health clinics in Selangor and Negeri Sembilan were interviewed using a structured questionnaire. The total subjects of the study were 556 patients. Eighty-five patients (15.3%) of patients; performed SMBG. However, 170 subjects were included in the statistical analysis, 85 patients who were not self-monitoring were randomly selected and was compared with 85 patients who were self-monitoring. Among those who performed SMBG, the majority (83.5%) monitored less than once per day and only 16.5% monitored at least once a day. One-third of patients adjusted their medications based on their SMBG results. The higher patient's level of education (p= 0.024, CI 1.29 - 35.3); the higher total family income (p= 0.041, CI 1.26 - 4.79); the longer duration of diabetes (p<0.01, CI 2.22 - 7.29); and treatment regime which includes insulin (p< 0.001, CI 2.05 -9.24) were significant predictors of SMBG practice. Although SMBG is recognised to be useful and effective in achieving diabetes control, this study has found that only a minority of patients with diabetes performed SMBG. Hence healthcare personnel must increase awareness on the importance of SMBG and strongly promote the practice among diabetic patients.

Fulltext Categorization of low cardiorespiratory fitness using obesity indices in non-smoking Singaporean women

Pua YH, Lim CK, Ang A

Obesity (Silver Spring), 2006 Nov;14(11):1992-9.
PMID: 17135616 DOI: 10.1038/oby.2006.233

OBJECTIVE: To revisit cut-off values of BMI, waist circumference (WC), and waist-to-stature ratio (WSR) based on their association with cardiorespiratory fitness (CRF). The derived cut-off points were compared with current values (BMI, 25.0 kg/m(2); WC, 80 cm) as recommended by the World Health Organization.
RESEARCH METHODS AND PROCEDURES: Anthropometric indices were measured in a cross sectional study of 358 Singaporean female employees of a large tertiary hospital (63% Singaporean Chinese, 28% Malays, and 9% Indians). CRF was determined by the 1-mile walk test. Receiver operating characteristic curves were constructed to determine cut-off points.
RESULTS: The cut-off points for BMI, WC, and WSR were 23.6 kg/m(2), 75.3 cm, and 0.48, respectively. The areas under the curve of BMI, WC, and WSR were 0.68, 0.74, and 0.74, respectively. For a given BMI, women with low CRF had higher WSR compared with women with high CRF.
DISCUSSION: These findings provide convergent evidence that the cut-off points for Singaporean women were lower than the World Health Organization's criteria but were in good agreement with those reported for Asians.

Ding CH, Teng CL, Koh CN

Med J Malaysia, 2006 Oct;61(4):399-404.
PMID: 17243515 MyJurnal

The Malaysian Ministry of Health has undertaken various campaigns on healthy lifestyle and health promotion over the years. The impact of these campaigns has been mixed and not well documented. This cross-sectional study evaluated the knowledge level of patients with and without diabetes in a large urban polyclinic using a 41-item questionnaire. One hundred and forty-nine adults (83 with diabetes, 66 without diabetes) participated in this study. Patients with diabetes had higher overall knowledge scores than those without diabetes (81.8% vs 64.0%, p < 0.001). While the overall knowledge of patients without diabetes appeared to be acceptable, several areas of knowledge deficiency were identified in this group--areas that should be filled by the on-going health promotion activities.

Acute renal failure after a holiday in the tropics

Guron G, Holmdahl J, Dotevall L

Clin. Nephrol., 2006 Dec;66(6):468-71.
PMID: 17176921 DOI: 10.5414/cnp66468

A 20-year-old, previously healthy woman, presented with high fever, headache and myalgia 3 days after her return from a holiday in Southeast Asia. Laboratory data on admission demonstrated a pronounced increase in plasma creatinine, marked thrombocytopenia and moderately elevated liver aminotransferases. After having ruled out malaria, dengue fever was primarily suspected and supportive intravenous fluid therapy was initiated. Still, 1 day after admission, platelet counts dropped even further and she became anuric although she did not appear hypovolemic. On day 2 after admission, urine production commenced spontaneously and the patient slowly recovered. All laboratory test results had returned to normal approximately 2 months later. Serological analysis for dengue fever was negative. It turned out that the patient had been trekking in the jungle while in Thailand and we, therefore, analyzed serology for Leptospira spirochetes which was clearly positive. The patient was diagnosed with leptospirosis which is a serious condition associated with a high mortality when complicated by acute renal failure. Differential diagnoses in patients with acute renal failure and tropical infections are reviewed. The importance of early recognition of leptospirosis, and prompt treatment with antibiotics in suspected cases, is emphasized.
