    The menopause is universal, but what about the climacteric? In an attempt to answer this question, a study was conducted in seven south-east Asian countries, namely, Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore and Taiwan. Samples of approximately 400 women in each country were questioned about a number of climacteric complaints, incontinence and dyspareunia, consultation of a physician, menopausal status and several background characteristics. Special care was taken to overcome linguistic and cultural problems, and the data collected were kept as objective as possible. From the results obtained we were able to show that the climacteric was indeed experienced in south-east Asian countries, although in a mild form. The prevalence of hot flushes and of sweating was lower than in western countries, but was nevertheless not negligible. The percentages of women who reported the more psychological types of complaint were similar to those in western countries. The occurrence of climacteric complaints affected perceived health status. A physician was consulted for climacteric complaints by 20% of the respondents, although this was most frequently associated with the occurrence of psychological complaints and less so with that of hot flushes and sweating. The median age at menopause (51.09) appeared to be within the ranges observed in western countries. Ethnic background and age at menarche were found to have a significant influence on age at menopause. The study clearly demonstrated that climacteric complaints occur in south-east Asia. The findings suggest, however, that vasomotor-complaint-related distress might be 'translated' into psychological complaints, which are more frequently considered to warrant consulting a physician.

  3. Childhood cruelty to animals: a tri-national study
    Mellor D, Yeow J, Mohd Hapidzal NF, Yamamoto T, Yokoyama A, Nobuzane Y
    Child Psychiatry Hum Dev, 2009 Dec;40(4):527-41.
    PMID: 19449100 DOI: 10.1007/s10578-009-0142-0
    Childhood cruelty to animals is a symptom of conduct disorder that has been linked to the perpetration of violence in later life. Research has identified several factors associated with its etiology, including social factors. However, no cross-cultural studies on this phenomenon have been reported. This study investigated childhood cruelty to animals in Japan, Australia and Malaysia. Parents of 1,358 children between the ages of 5 and 13 years completed the Children's Attitudes and Behaviours towards Animals questionnaire (CABTA) which assesses Typical and Malicious Cruelty to animals. Analyses revealed no overall differences between children from these countries on either scale. However, younger boys were more likely to be cruel than younger girls in each country, and younger children in Australia and Japan were more likely to be cruel that older children in those countries. The findings are discussed in relation to previous research, and recommendations for future studies are suggested.

  4. Outcome of 2 different types of operative techniques practiced for chronic subdural hematoma in Malaysia: an analysis
    Zakaraia AM, Adnan JS, Haspani MS, Naing NN, Abdullah JM
    Surg Neurol, 2008 Jun;69(6):608-15; discussion 616.
    PMID: 18486703 DOI: 10.1016/j.surneu.2007.01.054
    Traumatic chronic subdural hematomas in Malaysia are increasingly common in young patients after road traffic accidents as well as the elderly who fall at home. Most surgeons in this country manage these pathologies without irrigation, with only a drainage system. This has led to criticism that the recurrence rate might be higher when no irrigation is done and that rates are lower with irrigation and drainage. Thus, a study was done to look into the outcome of TCSH operated with and without irrigation, followed by drainage, to guide the surgeons in Malaysia as to what best could be done for these cases.

  5. Serum folate concentration, cognitive impairment, and DNA damage among elderly individuals in Malaysia
    Lee LK, Shahar S, Rajab N
    Nutr Res, 2009 May;29(5):327-34.
    PMID: 19555814 DOI: 10.1016/j.nutres.2009.05.006
    The notion that dietary factors affect cognitive function and subsequently the risk of dementia has increased over the years from a global viewpoint. Because low folate intake has been described to impair cognitive function, we tested the hypothesis that low serum folate concentration is associated with cognitive impairment and an attenuated increase in DNA damage. We investigated the relationship between serum folate concentration, cognitive impairment, and DNA damage among elderly people attending health clinics in Klang Valley, an urban area in Malaysia. Two hundred thirty-two participants, composed of 115 men (49.6%) and 117 women (50.4%), were involved; none of the patients were diagnosed with neuropsychiatric problems, nor where they terminally ill. Sociodemography and health variables were assessed through face-to-face interview. Cognitive impairment review was conducted through an Elderly Cognitive Assessment Questionnaire. The estimation of dietary intake, serum folate concentration, and DNA damage was individually analyzed using validated Dietary History Questionnaires, immunoassay methods, and an Alkaline Comet Assay study (10 mL of peripheral venous blood), respectively. Results indicated that more men had cognitive impairment (33.0%) and DNA damage (27.0% for percentage DNA in tail, 22.6% tail moment) compared with women (25.6%, 15.4%, and 15.4%, respectively) (P < .05 for all parameters), recording an average folate deficiency value of 13.9% (0.2% higher than women). Multivariate binary logistic regression analysis outlined the association of cognitive impairment with older age (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.35-5.57), smoking habits (OR, 5.12; 95% CI, 2.48-10.57), poor serum folate concentration (OR, 3.46; 95% CI, 1.26-9.52), and DNA damage (percentage DNA in tail) (OR, 13.70; 95% CI, 1.36-138.29). In conclusion, this study highlighted the important role of serum folate concentration for cognitive function and provided a concise picture regarding the elevated levels of oxidative DNA damage in peripheral lymphocytes.

  6. Fulltext A national database on children and adolescent with diabetes (e-DiCARE): results from April 2006 to June 2007
    Fuziah MZ, Hong JY, Zanariah H, Harun F, Chan SP, Rokiah P, et al.
    Med J Malaysia, 2008 Sep;63 Suppl C:37-40.
    PMID: 19230245
    In Malaysia, Diabetes in Children and Adolescents Registry (DiCARE) was launched nationwide in August 2006 to determine and monitor the number, the time trend of diabetes mellitus (DM) patients, their socio-demographic profiles, outcome of intervention and facilitate research using this registry. This is an on going real time register of diabetic patients < or = 20 years old via the e-DiCARE, an online registration system. To date were 240 patients notified from various states in Malaysia. The mean age was 12.51 years (1.08-19.75) and 46.4% were boys. The mean age at diagnosis was 8.31 +/- 4.13 years old with an estimated duration of diabetes of 4.32 +/- 3.55 years. A total of 166/240 (69.2%) have T1DM, 42/240 (17.5%) have T2DM and 18/240 (7.5%) have other types of DM. Basis of diagnosis was known in 162 patients with T1DM and 41 patients with T2DM. In T1DM patients, 6.0% of the girls and 19.1% boys were overweight or obese. As for T2DM, 64.3% had their BMI reported: 66.7% girls and 91.6% boys were overweight or obese. Most patients (80.4%) practiced home blood glucose monitoring. Patients were seen by dietitian (66.7%), diabetes educator (50.0%), and optometrist or ophthalmologist (45.0%). Only 10.8% attended diabetic camps. In the annual census of 117 patients, the mean HbAlc level was 10.0% + 2.2 (range 5.2 to 17.0%). The early results of DiCARE served as a starting point to improve the standard of care of DM among the young in the country.

    Ahmad F, Che Hamzah NA, Mustaffa N, Hua GS
    Hepatogastroenterology, 2011 07 15;58(110-111):1725-9.
    PMID: 21940338 DOI: 10.5754/hge11107
    BACKGROUND/AIMS: CYP3A4 is the major cytochrome in humans which shows reduced activity in chronic liver disease as well as in hepatic cirrhosis. The detection of this polymorphism may give an indication on the prognosis of patients having chronic viral hepatitis with superimposed hepatitis A infection. The aim of this study is to correlate the seroprevalence of anti-HAV antibodies in chronic liver disease patients having CYP3A4*18 polymorphisms.

    METHODOLOGY: This is a prospective study where patients (n=119) blood was tested for anti-HAVIgG and CYP3A4*18 polymorphism.

    RESULTS: The overall anti-HAV seroprevalence was 88.2%. The etiology of CLD was hepatitis B in 96 patients (80.7%) and hepatitis C in 23 patients (19.3%). There was a significant increase in the age of the prevalence of this disease after 30 years of age (p=0.008). CYP3A4*18 polymorphism was detected in 3 (2.5%) of the patients with chronic liver disease. However, there was no significant association between CP3A4*18 mutation and anti-HAV serology.

    CONCLUSIONS: Age was the most important factor in determining anti-HAV positivity. It is concluded that CYP3A4*18 genetic polymorphism does not play a main role in influencing the seroprevalence of anti-hepatitis A among chronic viral hepatitis B and C liver disease patients.

    Chlorpyrifos (CPF), an organophosphate pesticide inhibits acetylcholinesterase (AChE) and causes neuromuscular incoordination among children and elderly. The objectives of the present study were to compare the neurotoxic effects of dermal application of CPF on the cerebellum in the parameters of glial fibrillary acidic protein (GFAP) expression in young and adult mice and to correlate with the changes in acetylcholinesterase levels. Male Balb/c mice, 150 days old (adult) and 18 days old (young) were dermally applied with ½ LD(50) of CPF over the tails for 14 days. Serum AChE concentration was estimated and GFAP immunostaining was performed on sagittal paraffin sections through the vermis of cerebellum. Although reduced in both age-groups exposed to CPF, percentage of reduction in serum AChE was more in adult compared to the young. Under GFAP immunostaining, brown colour fibres and glial cells were observed in cerebellar cortex and medulla in both the experimental groups. The mean GFAP-positive glial cell count in cerebellar medulla per mm(2) of section was significantly (p

    The rapid expansion of the aged population in Malaysia is expected to greatly increase the number of persons with dementia in the country. However, data on dementia prevalence at the national level is lacking, and little is known about the sociodemographic risk factors and correlates of dementia. This paper describes a nationwide study of dementia prevalence and its sociodemographic risk factors and health correlates among older Malaysians.

  11. Fulltext Association of Arg72Pro of P53 polymorphism with colorectal cancer susceptibility risk in Malaysian population
    Aizat AA, Shahpudin SN, Mustapha MA, Zakaria Z, Sidek AS, Abu Hassan MR, et al.
    Asian Pac J Cancer Prev, 2011;12(11):2909-13.
    PMID: 22393962
    BACKGROUND: Colorectal cancer (CRC) results from the interaction between environmental exposures and genetic predisposition factors.

    AIMS: A case control study was designed and to investigate the genotype frequencies of P53Arg72Pro polymorphism in Malaysian CRC patients and healthy controls and to determine the associated risk of this polymorphism with CRC predisposition.

    METHODS: In this case-control study, peripheral blood samples of 202 sporadic CRC patients and 201 normal controls were collected, DNA extracted and genotyped using the polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) technique.

    RESULTS: Genotype analysis showed the frequency of homozygous variant (Pro/Pro) genotype (21%) to be significantly higher in cases compared to controls (13%), (p=0.013). On examining the association between variant genotypes and CRC risk, the Pro/Pro homozygous variant genotype showed significantly higher risk association with CRC susceptibility (OR: 2.047, CI: 1.063-4.044, p=0.033). When stratified according to age, we observed that, individuals aged above 50 years and carriers of pro/pro genotype had significantly higher risk with OR: 3.642, CI: 1.166-11.378, p=0.026.

    CONCLUSIONS: Our results suggest that the codon 72 SNP which results in amino acid substitution of Arginine to Proline in cell cycle regulatory gene P53, is associated with sporadic CRC risk and carriers of Pro/Pro genotype and more than 50 years old may have high susceptibility.

    PMID: 16771239
    The aims of this study were to determine the prevalence, knowledge and factors that influence smoking in Malay primary school children in Tumpat, Kelantan. A cross-sectional study was conducted in February 2004 among primary school children in Tumpat District. Two hundred-twelve children in standard one to six were randomly selected from three rural schools. An interview that included information on history of ever smoking, knowledge related to smoking and health, and potential factors that could influence smoking was done. Twenty-five children had previously smoked, with a prevalence of 11.8% (95%CI=8.0, 17.0) and 8 were current smokers (3.8%, 95%CI=1.2, 6.4). More than half (64.6%) of the children had a good knowledge of smoking. However, only 105 (49.5%) of them knew that passive smokers have a higher risk of developing diseases. Of those who had ever smoked, 12 (36.6%) were influenced by peers and 17 (51.5%) had a self-desire to smoke. The earliest age to start smoking was at 6 years. Factors found to be significantly associated with smoking on multivariate analysis were increasing age (OR=2.8, 95%CI=1.6, 5.1), being boys (OR=5.8, 95%CI=2.0, 16.8), being at second school level (standard 4, 5, 6)(OR=7.8, 95%CI=1.3, 45.3) and having other family members (excluding father) who smoked (OR=2.8, 95%CI=1.2, 6.5). However, having a father who smoked and a good knowledge were not reported as influencing factors.

    Liu WJ, Chew TF, Chiu AS, Zaki M
    Med J Malaysia, 2006 Dec;61(5):540-6.
    PMID: 17623953 MyJurnal
    The aims of this retrospective analysis were (i) to examine the trends of quality of life (QoL) scores and (ii) to identify the risk factors for QoL scores among 6908 dialysis patients entering dialysis between 1997 and 2002. The Spitzer QoL Index was the instrument used by the National Renal Registry of Malaysia to assess the QoL amongst dialysis patients. Demographic and biochemical data were analysed to identify risk factors for poor QoL. The median QoL-index score ranged between 9 and 10. Significant risk factors for poor QoL were female gender, age > 40, diabetes, cohort starting dialysis 2001-2002, haemodialysis modality, body mass index < 18.5, albumin < 30g/dL, cholesterol < 3.2 mmol/L, haemoglobin < 10 g/dL, diastolic blood pressure of > 90 mHg, iPTH < 100 pg/ml. The overall QoL of dialysis patients is satisfactory. The negative impact of diabetes and haemodialysis on QoL warrants further evaluation as each factor involves 50% and 90% of our dialysis population.

  18. RET and p53 expression in thyroid follicular adenoma: a study of 52 cases with 14 years follow-up
    Othman NH, Omar E, Mahmood MH, Madhavan M
    Malays J Pathol, 2005 Dec;27(2):91-8.
    PMID: 17191391
    Most previous studies on RET and p53 proteins have focused on thyroid papillary carcinoma. We investigated the role of RET and p53 protein expressions using immunohistochemistry on 52 cases of thyroid follicular adenomas and studied the follow-up records of these patients. The range of follow-up period was 3 to 14 years. The patients were between 15 and 71 years of age with a median age of 34.5 years. There were 46 females and 6 males. Except for 3 cases, all patients were Malays. The minimum volume of the tumour was 1000 mm3 and the maximum was 512,000 mm3 with a median of 270,000 mm3. Eleven (21.2%) cases showed RET expression. RET expression was not statistically significant when cross-tabulated against sex (p = 0.322), ethnicity (p = 0.518), age (p = 0.466) and symptom duration (p = 0.144). Six (11.5%) of 52 cases showed p53 immunopositivity. p53 expressions were also not significantly correlated to the clinical parameters above. There was no correlation between RET and p53 protein expressions. The only statistically significant finding was the association of tumour volume with duration of symptoms (p = 0.05). All patients are alive at the time of writing. 3 had recurrent goitre, 2 of these were diagnosed as colloid goitre while the third was a follicular lesion. One patient suffered from depression requiring anti-depressant treatment. In conclusion, unlike papillary carcinoma in which the roles of ret and p53 oncogenes are known, their roles in influencing the behaviour of follicular adenoma has not been ascertained.

    PMID: 16708729
    Depression is characterized by symptoms like disturbance in behavior, cognition and mood. This is commonly known to affect people aged 60 years and above especially those who are also afflicted with illnesses. The objectives of this study were to determine the prevalence of depression and its associated factors among the elderly in a tertiary care centre in Wilayah Persekutuan. A cross sectional study design was done. Stratified cluster sampling method was used to select the respondents. All elderly patients were selected from the orthopaedic, surgical, gynaecology and medical wards in a government hospital in Wilayah Persekutuan. A 30-item Geriatric Depression Scale questionnaire was used as a screening instrument. Out of the 246 elderly subjects, 198 were interviewed giving a response rate of 80.5%. The results showed that 54% of the elderly respondents were found to have depressive symptoms. Age (p=0.022), sex (p=0.008), ethnicity (p=0.022) and functional disabilities in bathing (p=0.001), grooming (p=0.007), dressing (p= 0.007), using the toilet (p=0.002), transferring from bed to chair and back (p=0.000), mobility (p=0.000) and climbing stairs (p=0.000) were all found to be significantly associated with depression among the elderly respondents. The outcome of this study will have an important impact on the implementation of the health policy for the elderly patients admitted to hospitals.

    PMID: 16295550
    This retrospective study was conducted at the National Tuberculosis Center (NTBC) where 252 HIV-positive patients coexisting with tuberculosis (TB/HIV) were examined. We found that patients with pulmonary (PTB) and extrapulmonary tuberculosis (EPT) had similar mean age. A higher sex ratio between male to female (10.7:1) was observed in patients with PTB. The other characteristics of patients with pulmonary and extrapulmonary tuberculosis were not statistically different from each other. Cough (88%) and hemoptysis were the most common presenting symptoms, significantly related to patients with PTB. Lymphadenopathy (33.5%) was the most common sign in patients with EPT. The majority of patients with pulmonary and extrapulmonary tuberculosis had CD4 cell counts of less than 200 cells/mm3 (range 0-1,179 with a median of 57 cells/mm3). Lung (89%) and miliary (55.6%) forms were the most frequent disease locations in patients with PTB and EPT, respectively. A higher percentage of patients with PTB (42%) were treated successfully with short-course (6 months) therapy, whereas in patients with EPT (43%) needed a longer period (9 months) for successful treatment. Of the patients who defaulted treatment, a higher proportion (87%) had PTB. No MDR-TB or relapse cases were found in this study.
