    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).

  3. 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.

    Int Urogynecol J, 2016 Nov;27(11):1653-1659.
    PMID: 27085545
    INTRODUCTION AND HYPOTHESIS: We hypothesized that transobturator tape (TOT) is safe and efficacious for the treatment of urodynamic stress incontinence in the long term.

    METHODS: We conducted a prospective study of patients with confirmed urodynamic stress incontinence (USI) who underwent a Monarc(TM) TOT procedure in a tertiary center between February 2006 and March 2009 without other concurrent surgical procedures. Urodynamics were conducted at 1 and 3 years postoperatively. Subjective evaluation included Incontinence Impact Questionnaire (IIQ-7), Urinary Distress Inventory Questionnaire (UDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Objective cure was defined as no urinary leakage demonstrable on provocative filling cystometry and/ or 1-h pad test of <2 g. Subjective cure was based on a negative response to question 3 in UDI-6. Paired-samples t test, chi-square, and Fisher exact tests were applied; p

  5. Quality of life: an assessment of the state of psychosocial rehabilitation of patients with schizophrenia in the community
    Hasanah CI, Razali MS
    J R Soc Promot Health, 2002 Dec;122(4):251-5.
    PMID: 12557735
    The subjective quality of life (QOL) of diabetic patients on oral hypoglycaemics was compared to schizophrenic patients who were well controlled with their antipsychotic medications. This comparison was made using the generic quality of life questionnaire produced by the World Health Organization QOL (WHOQOL) group, namely the WHOQOL-100. Statistical analysis showed that there was no significant difference in the psychological well-being and level of independence between the two groups. However, such measures revealed that the most impaired aspect of well-being in the schizophrenic group was the social relationship. Subjective QOL assessment is able to reveal deficits or handicaps that are obscure and probably difficult to appreciate on objective social and clinical evaluation. Such findings are valuable in planning the rehabilitative need of schizophrenic patients in the community.

    PMID: 8207502
    A cross-sectional exploratory survey was conducted in six West Malaysian schools involving 762 fifteen- to eighteen-year-old secondary school students. Periodontal health status was assessed using the Community Periodontal Index of Treatment Needs (CPITN), utilizing six index teeth to represent the six sextants of the mouth. The results indicated that 66.8% of the students examined had healthy gingiva (Score 0), 2.6% had bleeding of the gingiva on gentle probing, while 30.6% had calculus on their teeth. In terms of treatment needs, 35.0% of those examined needed oral hygiene education, 34.4%, on the other hand, required scaling. No student was found to require complex treatment. Sex-specific comparison revealed a slightly higher prevalence of calculus formation in male students. In terms of race, the Malays had a higher prevalence of calculus formation than either Chinese or Indians.

  7. Risk factors for developing neonatal septicaemia at a Malaysian hospital
    Wong NA, Hunt LP, Marlow N
    J Trop Pediatr, 1997 02;43(1):54-8.
    PMID: 9078832 DOI: 10.1093/tropej/43.1.54
    A case-control study of antecedents of neonatal septicaemia was performed using 50 cases of neonatal septicaemia and 73 comparison infants from a Malaysian hospital nursery. Multivariate analysis indicated the following independent risk factors: maternal primiparity, pre-eclampsia, prolonged rupture of membranes, twin pregnancy, prematurity, assisted ventilation, umbilical catheterization, and formula feeding. Although the spectrum of causative organisms varied between our study and past studies from Western countries, the risk factors for developing neonatal septicaemia were strikingly similar. Therefore, preventative guidelines based on risk factors described in Western countries, should help reduce the incidence of neonatal septicaemia at this Malaysian hospital.

    PMID: 1287605
    The maxillary casts of 320 Malaysian children were examined for the occurrence of the Carabelli trait on the maxillary first permanent molars. The total trait frequency was observed to be 52.2 per cent. Statistical analysis showed no sex dimorphism in the occurrence of the trait. Bilateral occurrence with a tendency towards concordance of expression between sides was also observed.

    Yusof Z, Isa Z
    J Oral Rehabil, 1994 Jan;21(1):77-86.
    PMID: 8133391
    The aims of the study were to determine the periodontal status of the teeth in contact with removable partial dentures (RPDs) and to compare them with other teeth in the opposing arch not related to any prosthesis. The periodontal status was also assessed in relation to the age of the dentures. Four hundred and twenty-seven patients treated with RPDs from 1981 to 1986 were recalled for examination. Prior to prosthetic treatment they were given periodontal treatment and fillings when required. Initially all were given oral hygiene instructions and motivation. They were reviewed regularly only on a short-term basis. Eighteen patients were suitable for the present study comprising of eight males and 10 females whose mean age was 41 years. The RPDs were in use from 1.5 to 8 years (mean 4.6 years). The following parameters were assessed: Plaque index (P1I), Gingival index (GI), loss of attachment (LA) and tooth mobility. The wearing of RPDs resulted in higher P1I, GI and LA compared to the controls and these differences were statistically significant. There was an increased frequency of higher P1I, GI and LA with the increase in denture age. Minor changes in tooth mobility were observed. It was concluded that the wearing of RPDs was detrimental to periodontal health in patients whose oral hygiene was less than adequate.

    Chiewsilp P, Mongkolsuk T, Sujirachato K, Junpong S, Rattanasombat K, Uden C
    J Med Assoc Thai, 1997 Sep;80 Suppl 1:S30-7.
    PMID: 9347643
    One hundred and two Southern Thai-Muslims (STM) from Nakhon Si Thammarat province were studied for HLA class I and II by SSP ARMS-PCR and PCR-SSO, respectively. The allele frequencies, haplotype frequencies, delta value and linkage disequilibrium between alleles were expressed. The most frequent alleles for HLA-A, HLA-B and HLA-C were A*24(02,03), A*11 (01,02), A*02(01,03,05-07,11): B*15(01,04-07,12,19,20), B*07(02-05), B*51(01-05)/B*52 (011,012); and Cw*07(01-03), Cw*04(01,02), Cw*08(01-03), respectively. The HLA class II alleles frequently found were DRB1*1202, DRB1*15021, DRB1*0701; DRB3*0301; DRB5* 0101; DQA1*0101, DQA1*0103, DQA1*0601; DQB1*0301, DQB1*0501, DQB1*0201; and DPB1*1301, DPB1*2301 and DPB1*0501. Two common HLA class I and II haplotypes with significant linkage disequilibrium were A*24 (02,03)-Cw*08 (01-03)-B*15 (01,04-07,12,19,20) -DRB1*1202 and A*33 (01,02)-Cw*0302-B*5801-DQB1*0201. The absence of B*27 and DRB1 *1401, the presence of A*2301 and high frequency of A*68 were observed in STM.

    J Med Assoc Thai, 1997 Sep;80 Suppl 1:S25-9.
    PMID: 9347642
    The HLA-A*02 subtyping in Thais was conducted and included in the 12th International Histocompatibility Workshop (12WS). A total of 81 randomized individuals previously serologically or DNA typed as A2 were studied for A2 subtypings. The subjects consisted of 32 Southern Thai-Muslims (STM) and 49 Central Thais (CT). The 12WS HLA-A*02 subtyping DNA typing kit was employed. The most common A*02 subtypes in STM were A*0203,*0201 and *0207 while they were A*0203, *0207 and *0201 in CT. A*0202, *0204, *0208, *0209, *0212, *0213, *0214, *0215, *0216 and *0217 were not found in both STM and CT. The 12WS data indicated that A*0201 was also the most frequent allele of A*2 among North-East Asians. A2 subtype study in 32 STM revealed that 2 in 8 of A*0201 showed the absence of bands at 813 bp and 705 bp with primer mix number 03A and 517A and weak reaction band with primer mix number 33A. In addition, 3 subjects with A*0201 variations have one nucleotide difference in exon 2 by sequence base typing (by MGJ. Tilanus) which will be reported separately.

  12. Preventive and promotive medicine in ambulatory clinical practice: a prospective simulated patient study
    Wong YY, Nordin M, Suleiman AB
    Int J Qual Health Care, 1995 Dec;7(4):333-41.
    PMID: 8820209 DOI: 10.1093/intqhc/7.4.333
    OBJECTIVE: This study examines the extent to which preventive and promotive advice is integrated into the clinical practice of doctors.
    STUDY DESIGN: Using a cross-sectional descriptive survey design, the study compares the performance of doctors in giving healthy lifestyle advice for five clinical conditions, their perceived practice and their rating on the importance of disseminating selected key lifestyle messages.
    DATA EXTRACTION METHODS: A total of 28 volunteers were trained to simulate the five clinical conditions which required related health advice and to rate the doctors' performance with the use of a prepared checklist. Simulated patient ratings of 343 doctor-patient encounters provided the data on doctors' health promotion efforts for the selected clinical conditions. A post-visit self-administered questionnaire survey of a sub-sample of 100 doctors gave an insight into their opinions and perceived practice.
    PRINCIPAL FINDINGS: Only in 49% of the instances was a health promotion message given. The doctors' encouraging interest in health education and health promotion and their positive perceptions of their volume of healthy lifestyle counselling were not borne out in actual clinical practice.
    CONCLUSIONS: The results indicate that the extent of preventive and promotive health education in both the public and private health sectors is unacceptably low. The matter needs to be addressed through training programmes as well as the formulation of clear health promotion priorities and strategies in Malaysia.

  13. Dentists' attitudes toward auxiliaries in Malaysia
    Razak IA, Lind OP
    Community Dent Health, 1994 Mar;11(1):24-8.
    PMID: 8193979
    A postal questionnaire survey concerning dentists' attitudes toward auxiliaries in Malaysia resulted in a 73.1 per cent response rate. The result of the study indicates that whilst the majority of the dentists agreed that dental auxiliaries usually increase productivity and permit the dentists to devote more time for more challenging tasks, a majority felt uncomfortable to be held accountable for the performance of auxiliaries. A majority of the dentists agreed that dental auxiliaries work best under direct supervision. The perceived value of the auxiliaries was more positive among public sector dentists as compared to private practitioners. Almost three-quarters of the dentists were positive towards legalising properly trained auxiliaries to work in private practice performing mainly preventive procedures. The implications of these findings relative to existing regulations, mode of practice and the future prospect in the delivery of oral health care are discussed.

  14. Breastfeeding at 6 weeks and predictive factors
    Chye JK, Zain Z, Lim WL, Lim CT
    J Trop Pediatr, 1997 10;43(5):287-92.
    PMID: 9364127 DOI: 10.1093/tropej/43.5.287
    Despite the numerous changes made in accordance with the Baby Friendly Hospital Initiative at the University Hospital, Kuala Lumpur, the low rates of breastfeeding have persisted. This study aims to examine the current trend in infant feeding, and the influences of some perinatal and sociodemographic factors on breastfeeding. Five-hundred mothers with singleton pregnancies and healthy infants were interviewed at 6 weeks post-partum. Only 124 (25 per cent) mothers were practising exclusive breastfeeding (EBF), and 132 (26 per cent) mothers were using exclusive infant formula feeding (EIF). On logistic regression analyses, mothers who followed EBF were more likely to have had antenatal plans to breastfeed (Odds ratio 2.44, 95 per cent confidence interval 1.75-3.45), not in paid employment post-natally (OR 1.76, 95 per cent CI 1.31-2.36), of older age group (> 27 years) (OR 1.48, 95 per cent CI 1.13-1.93), had female infants (OR 1.38, 95 per cent CI 1.05-1.80) and of Indian ethnicity (compared to Chinese) (OR 3.87, 95 per cent CI 2.16-6.89). Breastfeeding difficulties were associated with decreased odds of EBF (OR 0.21, 95 per cent CI 0.13-0.34). Parental education, fathers' ages and incomes, primigravida status, Caesarean section, present of episiotomy, late first breastfeed, phototherapy, and length of hospital stay were not significant predictors of failure of EBF. In comparison, predictive factors for increased use of EIF were mothers who have had breastfeeding difficulties, < or = 9 years of schooling, and of Chinese descent. In conclusions, the overall rate of EBF by 6 weeks of age in infants born in this urban hospital had remained poor. The adverse factors for EBF identified in this study warrant further in-depth studies to determine effective ways of improving EBF rates.

    PMID: 8626179
    A house to house random survey on elderly subjects was undertaken in the District of Klang in Malaysia. The objective of this study was to investigate the prevalence of oral mucosal lesions (OML) among the elderly in this area. The primary units in the sampling frame were the Enumeration Blocks (EBs) as defined under the population census. All households of the selected EBs were considered as sampling units and members aged 60 and above were considered as respondents. There was a slight preponderance of females, with the Malays comprising the majority of the subjects. Of the 486 respondents, mean aged 69.1 +/- 7.3 yr, 111 had at least one oral mucosal lesion, a prevalence of 22.8%. A total of 145 lesions were detected. The prevalence of OML was highest among Indians and least among the Chinese. The most common finding was tongue lesions, recording a prevalence of 10.7%, followed by oral pigmentation (4.9%) and white lesions (4.3%). Denture related lesions were comparatively low at 2.5%. Two cases of oral cancer if representative would give a relatively high prevalence of 0.4%.

    PMID: 1782894
    The efficacy of two ultrasonic units in shaping curved canals in teeth were compared. Twenty teeth were instrumented using the Cavi-Endo unit at a power setting 1 using the technique recommended by the manufacturer. Another group of 20 teeth received similar treatment but were instrumented with the Enac unit. The time taken to instrument each canal was recorded. The pre- and post-instrumented radiographs of the teeth of x 10 magnification were taken using a microfocal technique. The radiographs were subjected to a subtraction technique to result in composite images of the pre- and post-instrumented shapes. The canal shape and the incidence of elbows were evaluated using various measurements taken from the radiographs. The manner the dentine was removed was similar in both groups. All canals exhibited unequal removal along the canal with more dentine being removed at the coronal end. The Enac group exhibited a higher incidence of elbows which occurred further apically than those in the Cavi-Endo group. There was no significant difference between groups in the following: time of instrumentation, amount of apical and coronal canal enlargement, apical deviation and change in width at the elbow. These findings were no different from those of another study using simulated canals.

    PMID: 15190624
    In Malaysia, there is limited information on the mortality and morbidity after an acute stroke in hospitalised patients. The objective of the study was to identify the type, time of onset, and frequency of medical and neurological complications following an acute ischaemic stroke. Consecutive patients with acute ischaemic stroke who were admitted to Hospital Universiti Kebangsaan Malaysia from June 2000 to January 2001 were observed. The complication rate was 20.9%. The most common individual complication was pneumonia (12.3%), followed by septicaemia (11.0%), urinary tract infection (4.3%), and upper gastrointestinal haemorrhage (3.7%). The overall mean length of stay was 7.48 days. The independent risk factors for complications were diabetes mellitus (OR 2.87; 95%CI 1.06 to 7.78), middle cerebral artery (MCA) infarcts (OR 10.0; 95%CI 4.1 to 24.3), and Glasgow coma score (GCS) less than 9(OR 3.8; 95%CI 1.03 to 14.3). Infection was the commonest complication observed. Patients with diabetes mellitus, poor GCS and large MCA infarcts had a higher risk of developing complications.

    Med J Malaysia, 2003 Oct;58(4):490-8.
    PMID: 15190623
    A study was done on survival of patients surgically treated for lung cancer from 1995-2001. The average operative rate for 852 patients was 4.8%. In 67 surgically treated patients (54M, 13F), the commonest histological type was squamous cell carcinoma (52.2%) followed by adenocarcinoma (26.9%). The surgical-pathological stage was stage I in 52.2%. Postoperatively, five-year survival was 29%, with a median survival of 27 months. Completeness of resection was the foremost determinant of survival outcome and stage higher than stage I was an adverse prognostic factor. These results indicate that the current outlook for lung cancer patients remains poor.

  20. Fulltext POSSUM--a model for surgical outcome audit in quality care
    Ng KJ, Yii MK
    Med J Malaysia, 2003 Oct;58(4):516-21.
    PMID: 15190626
    Comparative surgical audit to monitor quality of care should be performed with a risk-adjusted scoring system rather than using crude morbidity and mortality rates. A validated and widely applied risk adjusted scoring system, P-POSSUM (Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality) methodology, was applied to a prospective series of predominantly general surgical patients at the Sarawak General Hospital, Kuching over a six months period. The patients were grouped into four risk groups. The observed mortality rates were not significantly different from predicted rates, showing that the quality of surgical care was at par with typical western series. The simplicity and advantages of this scoring system over other auditing tools are discussed. The P-POSSUM methodology could form the basis of local comparative surgical audit for assessment and maintenance of quality care.
