Background: The high prevalence and impacts of orofacial pain (OFP) have caused major sufferings to individuals and society. The purpose of the study was to investigate the problems and impacts of OFP among a group of Malaysian aborigines. The objectives were to determine (i) the prevalence, aetiology, duration, severity, types and persistence of OFP during the past 3 months preceding the study; (ii) its associated impact on daily performance; and (iii) the measures taken for pain relief.
Methods: This is a cross sectional study carried out in Kuala Lipis, Pahang involving 6 villages of Orang Asli Bateq and Semai. Study sample was chosen using convenient sampling including adults aged 16 years and above. Participants were invited for an interview using structured questionnaire followed by clinical examination. Data analysis was carried out using SPSS ver12.
Results: Response rate was low at 20% (n = 140). Over one-quarter (26.4%) of the sample experienced OFP in the previous 3 months. Toothache was found to be the main aetiology (83.3%) followed by gingival pain (18.9%), temporomandibular joint (10.8%) and facial pain (8.1%). Mean duration of pain was 9.8 days for toothache, 162.4 days for gingival pain, 7.3 days for TMJ and 5.7 days for facial pain. Of those who had OFP, over half rated the pain as moderate (37.8%) and severe (29.7%) and most of the pain was ‘intermittent’ in nature (81.1%). Over half (62.2%) admitted the pain had disappeared during the interview. In terms of pain relief, 56.8% of the sample used traditional medicine. The pain had impacted on the chewing ability (70.3%, p=0.01), ability to sleep at night (73.0%, p<0.001), levels of anxiety (70.3%), ability to perform daily chores (33.3%) and social life (35.1%) of the Orang Asli sample.
Conclusion: This study suggests the prevalence of OFP was high among the Orang Asli sample, which imposed considerable physical and psychological impacts on daily life.

Roohi, S.A., Choon-Sian, L, Shalimar, A., Tan,G.H., Naicker, A.S.

Malays Orthop J, 2007;1(1):26-28.

MyJurnal

Palmaris longus is a dispensable muscle with a long tendon which is very useful in reconstructive surgery. It is absent 2.8 to 24% of the population depending on the race/ethnicity studied. Four hundred and fifty healthy subjects (equally distributed among Malaysia's 3 major ethnic groups) were clinically examined for the presence or absence of palmaris longus. This tendon was found to be absent unilaterally in 6.4% of study subjects, and bilaterally in 2.9% of study participants. Malays have a high prevalence of palmaris longus absence at 11.3% followed closely by Indians at 10.7% whilst Chinese had a low absence rate of 6.0%.

Generally, the karyotype profile of Down Syndrome has been reported to be full trisomy 21 in 92% of patients, mosaic trisomy 21 in 4% of patients and translocation involving chromosome 21 in 4% of patients in most of the population groups worldwide. But, karyotype analysis of 149 DS patients at the Human Genome Center, USM, during the past five years revealed that free trisomy accounted for 94.6%, mosaic trisomy 21 for 4.7% and translocation involving chromosome 21 in 0.7% of the Down Syndrome etiology in North East Malaysian population, indicating a low frequency of translocation DS in this region. Here, we report one case of translocation Down Syndrome encountered during karyotype analysis of 149 DS cases. Karyotype showed a robertsonian translocation where an entire extra chromosome 21 was attached to the centromere of one of the chromosome 14, resulting in a derivative chromosome 14 with attached chromosome 21. Karyotype analysis of the parents revealed a normal 46,XY pattern for father and 46,XX pattern for mother indicating that this robertsonian translocation had arisen de novo either prior to or at conception.

MyJurnal

Home Care Nursing Program (HCNP) at HUKM was started in 1998 and evaluation of the program was required. The objective of this study is to evaluate the effectiveness of HCNP on stroke rehabilitation at HUKM. A retrospective study using a matched pair design involving 69 stroke patients admitted to HUKM from August 1998 to December 2000 was carried out. The participants of this study were the HCNP group (n=35), and Non- HCNP (n=34). The matching was based on five criteria; age, sex, race, data of admission and severity of disability. The HCNP group was identified through data at the HCNP unit and their medical reports were traced. For the Non-HCNP group, the participants were identified based on criteria which were similar to that of the HCNP group. Based on the criteria identified, there was no significant difference between the two groups. The Activities of Daily Living was measured using the Modified Barthel Index twice; once on admission (based on record) and one post stroke. The t-test was applied to parametric data and non-parametric data; Chi-square was used to detect any significant relationships between the scores of the two groups. Results showed no significant difference (p=0.1990) in ADL on admission and ADL post stroke patients between the two groups. However, there were significant difference (HCNP p=0.000 and Non-HCNP p=0.000) in ADL on admission and post stroke for stroke patients who sought alternative treatment compared to those who had not.

Angiotensin-1 converting enzyme I/D gene polymorphism: scenario in Malaysia

Jayapalan JJ, Muniandy S, Chan SP

Southeast Asian J. Trop. Med. Public Health, 2008 Sep;39(5):917-21.

PMID: 19058590

Discrepancies in angiotensin-1 converting enzyme (ACE) allele genetic susceptibility with disease etiology have been attributed to ethnic differences. We investigated ACE gene polymorphism of the multiethnic Malaysian population by utilizing nested polymerase chain reaction. Allelic frequency of 0.65 and 0.35 for I and D allele, respectively in the pooled population was comparable with other Asian populations. A significant association was found between the Malaysian ethnic groups and ACE I/D genotype. The II genotype was found at higher frequency among the Malays but a greater frequency of DD genotype among Indians.

Am J Pharm Educ, 2009 Feb 19;73(1):15.

PMID: 19513153

OBJECTIVE: To evaluate the level of knowledge, attitudes, and risk perceptions of University Sains Malaysia final-year pharmacy students regarding human immunodeficiency virus (HIV) and acquired immunity deficiency syndrome (AIDS).

METHOD: A cross-sectional study among pharmacy students. Data were analyzed with Chi-square to find difference at p value < 0.05.

RESULTS: The majority of students (83.07%) responded showing a difference in gender and race. Students showed low willingness (9.2%) to assist patients and low confidence (36.1%) in their education about HIV/AIDS patients. Students recommended HIV testing for health care professionals (69.4%) and patients (75.9%) before surgical procedures. Students knew little about Post Exposure Prophylaxis (18.5%) or about the time for HIV to develop into AIDS (57.4%). About 40% of students were unaware of the inability of antivirals to treat HIV/AIDS. Students had low awareness for opportunistic infections (18.5%), and low agreement on competency to treat and counsel HIV patients (12.9%).

CONCLUSION: The study highlighted students' misconceptions, negative attitudes, and risk perceptions towards HIV/AIDS.

HPV information needs, educational messages and channel of delivery preferences: views from developing country with multiethnic populations

Wong LP

Vaccine, 2009 Feb 25;27(9):1410-5.

PMID: 19150379 DOI: 10.1016/j.vaccine.2008.12.045

This qualitative study used focus group discussions (FGDs) to evaluate information needed in order to make informed human papillomavirus (HPV) vaccination decision, opinion on the most acceptable public education messages, and channel of delivery in a multiethnic, multicultural and multireligion country. A total of 19 FGDs were conducted among mothers of eligible vaccinees, young women eligible for the vaccine, and men. Messages that carry accurate information about HPV-cervical cancer link, the HPV preventive vaccines and at the same time minimize the stigma of a sexually transmitted infection (STI) vaccine were preferred. Educational messages for future HPV educational intervention were developed and methods to effectively convey to the public the need for HPV vaccination were identified. The findings serve as a basis for future intervention to develop research-based communication materials and strategies.

Fulltext Helicobacter pylori cagA gene variants in Malaysians of different ethnicity

Mohamed R, Hanafiah A, Rose IM, Manaf MR, Abdullah SA, Sagap I, et al.

Eur J Clin Microbiol Infect Dis, 2009 Jul;28(7):865-9.

PMID: 19247698 DOI: 10.1007/s10096-009-0712-x

We have defined DNA repeat variability in the 3'-terminus of the cagA gene of Helicobacter pylori strains from Malaysian patients of different ethnicities. We identified different alleles based on the EPIYA repeats. cagA types A-B-D and A-B-B-D are more similar to the sequence of Japanese strains, whereas cagA types A-B-C, A-B-C-C, A-B and A-C displayed similarity to strain 26695 sequences. A significant association was found between cagA genotypes and patients' ethnicity, with cagA type A-B-D being predominantly isolated from Chinese patients and cagA type A-B-C from Malays and Indians. Our data further corroborate the possibility that variant biological activity of CagA may affect the host specificity and/or pathogenicity of H. pylori.

Fulltext Does the granting of legal privileges as an indigenous people help to reduce health disparities? Evidence from New Zealand and Malaysia

Phua KL

Pac Health Dialog, 2009 Nov;15(2):117-27.

PMID: 20443525

Both the Maori of New Zealand and the Orang Asli of Malaysia are indigenous peoples who have been subjected to prejudice, discrimination and displacement in its various forms by other ethnic groups in their respective countries. However, owing to changes in the socio-political climate, they have been granted rights (including legal privileges) in more recent times. Data pertaining to the health and socio-economic status of the Maori and the Orang Asli are analysed to see if the granting of legal privileges has made any difference for the two communities. One conclusion is that legal privileges (and the granting of special status) do not appear to work well in terms of reducing health and socio-economic gaps.

Jurnal Psikologi Malaysia, 2009;olume 23:11-17.

This qualitative study reviewed the concept of Mat Rempit. This study used two methods of interviews. Firstly, individual interviews were conducted with 16 individuals who were from a school in Semenyih, Selangor and they had been involved in rempit activities. Secondly,focus group interviews were conducted involving three groups of individuals who were charged under Section 42 for driving recklessly their motorcycles in Penang, Johor Baharu and Kuala Lumpur. The main results of interviews indicate that rempit can be defined as any activity involving a motorcycle racing team of at least two people Generally, the race comprised various actions such as doing a sprint, or a lap and also stunts (such as, a wheelie or wheekang). In addition, there is ramping of engines of molorcycles and creating excessively loud sounds as well as shouting and showing hand signals. A Mat Rempit is a person involved in these activities. Other related findings and implications are also discussed.

Fulltext Dermatoglyphics: comparison between Negritos Orang Asli and the Malays, Chinese and Indian

Ismail E, Abdul Razak S, Selamat L, Gurusamy R, Zariman H, Shahrudin MS, et al.

Sains Malaysiana, 2009 6;38:947-952.

Dermatoglyphic traits are formed under genetic control during early gestation and do not change through the entire life. A few studies have shown that dermatoglyphic traits were conservative in their evolution and were different between and within population groups. The objective of this study was to compare the variability of palm dermatoglyphs in three main populations i.e. Malay, Chinese, Indian and five sub-ethnic population of Negritos’ Orang Asli i.e. Bateq, Jahai, Kintak, Kensiu and Lanoh. We utilised fingerprints and palms of 390 healthy adult individuals, counted the total ridge for ten fingers
(TRC), a-b ridge counts (a-b RC) on palms, examined widening of the atd-angle, and classified the digital pattern configuration of arches, whorls, ulnar, and radial loops for all fingers. Variables obtained from both palm did not show any differences between males and females for all populations. TRC, a-b RC and atd-angle were the highest for Kensiu and were later on specially described to be in a group of its own by ANOVA and TUKEY test for TRC and a-b RC. The same test has put Chinese in a group of its own for atd-angle. Only a-b RC clearly separate Orang Asli populations from the three main races. Whorls and ulnar loops were the most predominant pattern in all groups. Malays and Chinese had similar distributional patterns for each ten fingers. Indian and Jahai similarly mimic each other, while Bateq has the reversal pattern distribution to them both. Kintak and Lanoh halfly mimics each other pattern and Kensiu had its own unique pattern. In conclusion, races, patterns, and pattern frequencies were related to each other and can be used to differentiate different races or Orang Asli
sub-ethnics. This study documents for the first time the comparative dermatoglyphic traits between Malaysian main races with Orang Asli populations show a list of informative variables that can be used to identify them as well as suggesting it’s used as a tool in tracing the etnohistorical background of populations.

Molecular analysis of HLA Class I and Class II genes in four indigenous Malaysian populations

Jinam TA, Saitou N, Edo J, Mahmood A, Phipps ME

Tissue Antigens, 2010 Feb;75(2):151-8.

PMID: 20003135 DOI: 10.1111/j.1399-0039.2009.01417.x

This is the first report of high-resolution human leukocyte antigen (HLA) typing in four indigenous groups in Malaysia. A total of 99 normal, healthy participants representing the Negrito (Jehai and Kensiu), Proto-Malay (Temuan) and a native group of Borneo (Bidayuh) were typed for HLA-A, -B, -DRB1 and -DQB1 genes using sequence-based typing. Eleven HLA-A, 26 HLA-B, 16 HLA-DRB1 and 14 HLA-DQB1 alleles were detected, including a new allele, HLA-B*3589 in the Jehai. Highly frequent alleles were A*2407, B*1513, B*1801, DRB1*0901, DRB1*1202, DRB1*1502, DQB1*0303 and DQB1*0502. Principal component analysis based on high-resolution HLA-A, -B and -DRB1 allele frequencies showed close affinities among all four groups, including the Negritos, with other Southeast Asian populations. These results showed the scope of HLA diversity in these indigenous minority groups and may prove beneficial for future disease association, anthropological and forensic studies.

PMID: 20196825 DOI: 10.1111/j.1399-0039.2009.01410.x

One hundred and fifty-eight Kadazan, Iban and Bidayuh individuals registered with the Malaysian Marrow Donor Registry were typed for human leukocyte antigen (HLA)-A, HLA-B and HLA-DR. Six, seven and eight HLA-A alleles as well as 13, 15 and 16 HLA-B alleles were detected in the Kadazan, Bidayuh and Iban, respectively. The most common HLA-A allele in all three groups was HLA-A*24 with a frequency of 0.456, 0.490 and 0.422 in the Kadazan, Bidayuh and Iban, respectively. The most common HLA-B allele detected in the Kadazan was HLA-B*40 with a frequency of 0.333; for the Bidayuh and the Iban it was HLA-B*15 with a frequency of 0.460 and 0.275, respectively. The HLA-DR allele with the highest frequency in the Kadazan was HLA-DR*1502 with a frequency of 0.500. In the Iban and the Bidayuh, HLA-DRB1*1202 was the most common DR allele with frequencies of 0.235 and 0.310, respectively. The two most common haplotypes for the Kadazan are A*34-B*38-DR*1502 and A*24-B*40-DR*0405, whereas for the Bidayuh they are A*24-B*15-DR*1602 and A*24-B*35-DR*1202 and for the Iban they are A*34-*B15-DR*1502 and A*24-B*15-DR*1202.
