    Ong TA, Yip CH
    Asian J Surg, 2003 Jul;26(3):169-75.
    PMID: 12925293
    OBJECTIVE: To study the impact of various clinicopathological factors on short-term survival in a cohort of breast cancer patients treated at the University of Malaya Medical Centre (UMMC).
    METHODS: All cases of breast cancer treated at UMMC from January 1999 to June 2001, except for stage IV disease, were included in the study. Survival analysis was carried out using Kaplan-Meier for univariate analysis and Cox regression for multivariate analysis. The log-rank test was used to test the significance of differences between the different survival curves.
    RESULTS: A total of 385 patients were included. The mean patient age at presentation was 50.3 years (SD, 11.4); 198 (51.4%) patients had lymph node-positive disease, and 187 (48.6%) had node-negative disease. The mean follow-up period was 18.7 months (SD, 8.8). The Malay ethnic group, tumours of larger size, node-positive disease, more than five positive lymph nodes, oestrogen receptor (ER) negativity and the presence of lymphovascular invasion were significant prognostic factors for shorter recurrence-free survival (RFS) in the univariate analysis. In the multivariate analysis, ER negativity was the only independent adverse prognostic factor for RFS. For overall survival (OS), tumours of larger size, node-positive disease, more than five positive lymph nodes, ER negativity and high grade tumours were associated with significantly shorter OS. However, more than five positive lymph nodes was the only independent prognostic factor for shorter OS in the multivariate analysis. Further multivariate analysis of the patients with node-positive disease showed that the Malay ethnic group, ER negativity and more than five positive lymph nodes were independent prognostic factors for shorter RFS. On the other hand, ER negativity and more than five positive lymph nodes were independent negative prognostic factors for OS in this subgroup of patients.
    CONCLUSION: The evaluation of various prognostic factors would provide useful information on disease progression in local patients, especially for the planning of adjuvant therapies and follow-up protocols. Differences in the pattern of breast cancer among the different ethnic groups in Malaysia warrant further studies.

  2. Postoperative venous thromboembolism in Asia: a critical appraisal of its incidence
    Liew NC, Moissinac K, Gul Y
    Asian J Surg, 2003 Jul;26(3):154-8.
    PMID: 12925290
    Venous thromboembolism (VTE) has historically been perceived to be a rare disorder in Asia. However, new evidence has emerged recently that contradicts this perception. The question of routine VTE prophylaxis has been hotly debated in Asia due to disagreement on its incidence. We reviewed and analysed studies on postoperative VTE in Asian patients to determine if the condition was indeed rare and if the routine prophylactic measures as recommended by internationally accepted guidelines should be adopted in Asia.

    Abdominal aortic aneurysm (AAA) repairs represent a significant workload in vascular surgery in Asia. This study aimed to audit AAA surgery and evaluate the application of the Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM) in an Asian vascular unit for standard of care. Eighty-five consecutive surgical patients with AAA from a prospective vascular database from July 1996 to December 2001 in Sarawak were available for analysis. Comparisons between predicted deaths by P-POSSUM and observed deaths in both urgency of surgery categories (elective, urgent, emergency ruptures) and risk range groups (0-5%, >5-15%, >15-50%, >50-100%) were made. No significant difference was found between the predicted and observed rates of death for elective, urgent and emergency AAA repairs. The observed mortality rates were 5%, 18% and 30%, respectively. The observed rates of death were also comparable to P-POSSUM predicted rates of death in the various risk range groups. The POSSUM score used with the P-POSSUM mortality equation is easy to use and applicable as a comparative vascular auditing tool in Asia.

  4. Women's autonomy and child survival: a comparison of Muslims and non-Muslims in four Asian countries
    Ghuman SJ
    Demography, 2003 Aug;40(3):419-36.
    PMID: 12962056 DOI: 10.1353/dem.2003.0021
    In this article, I evaluate the hypothesis that higher infant and child mortality among Muslim populations is related to the lower autonomy of Muslim women using data from 15 pairs of Muslim and non-Muslim communities in India, Malaysia, the Philippines, and Thailand. Women's autonomy in various spheres is not consistently lower in Muslim than in non-Muslim settings. Both across and within communities, the association between women's autonomy and mortality is weak, and measures of autonomy or socioeconomic status are generally of limited import for understanding the Muslim disadvantage in children's survival.

  5. Fulltext Survival of patients surgically treated for lung cancer
    Hooi LN, Hamzah KM, Jahizah H
    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.

  6. Fulltext The impact of diabetes mellitus on in-hospital stroke mortality
    Hamidon BB, Raymond AA
    J Postgrad Med, 2003 Oct-Dec;49(4):307-9; discussion 309-10.
    PMID: 14699227
    Background and purpose: Diabetes mellitus is a strong risk factor for stroke. However, the prognosis in terms of mortality after a stroke is still unclear, especially in diabetic patients. The main purpose of this study was to compare and evaluate the features of stroke in patients having diabetes mellitus with those without diabetes mellitus and to identify factors that influence survival following a stroke.

    Subjects and methods: In a prospective hospital-based study consecutive patients with acute ischaemic stroke were enrolled. A single observer, using predefined diagnostic criteria recorded the demographics, risk factors and the type of stroke and deaths that occurred during the in-patient period.

    Results: One hundred and sixty-three patients with acute ischaemic stroke were enrolled in the study. Type 2 diabetes mellitus was present in 90 (55.2%) patients. Diabetes was a significant independent predictor of mortality (OR 4.88; 95%CI 1.25-19.1). Among the diabetic patients middle cerebral artery (MCA) territory infarct (OR 34.8, 95%CI 4.5-269.4) and Glasgow coma score (GCS) less than 9 (OR 12.3, 95%CI 3.7-198.1) were independent predictors of mortality.

    Conclusions: MCA infarcts and poor conscious level increase the mortality in diabetic patients with stroke. Mortality is also significantly related to a high level of blood glucose at admission.

    PMID: 15272757
    To characterize the demographic profiles, clinical features, radiological patterns and outcomes of treatment of HIV-infected TB patients, a descriptive study was carried out on 149 HIV-infected TB cases diagnosed from 1998 through 2001 at Kota Bharu Hospital, Kelantan, Malaysia. The majority of the patients were males (94.6%), single (45.0%), ethnic Malay (94.0%) with a mean age of 34 years (standard deviation 7.8, range 18-76). The most common HIV transmission category was through injecting drug use (73.8%) and being the inmates or former inhabitants of drug rehabilitation centers and prisons were the commonest high-risk groups. One hundred and seventeen patients were diagnosed as having pulmonary TB, while about 20% were extra-pulmonary in type with 9 cases of milliary TB. The majority (45%) presented with cough symptoms while only 51% had a positive sputum smear. Fifty-five percent were found to have pulmonary lesions on chest x-ray, such as localized, milliary or diffuse pulmonary infiltrates, or opacities. Eight (5.4%) had pleural lesions while another 8 cases had hilar or mediastinal lymph node lesions. Overall, fifty-eight (38.9%) patients had died by the completion of data collection. The median weeks or survival from the time of starting TB treatment was 13.5 (range 1-56) and the majority of them (74%) died without completing the 6-month regime of treatment.

  8. Smoothing a discrete hazard function for the number of patients colonized with Methicillin-resistant Staphylococcus Aureus in an intensive care unit
    Ismail NA, Pettitt AN
    Stat Med, 2004 Apr 30;23(8):1247-58.
    PMID: 15083481
    A new method for estimating the time to colonization of Methicillin-resistant Staphylococcus Aureus (MRSA) patients is developed in this paper. The time to colonization of MRSA is modelled using a Bayesian smoothing approach for the hazard function. There are two prior models discussed in this paper: the first difference prior and the second difference prior. The second difference prior model gives smoother estimates of the hazard functions and, when applied to data from an intensive care unit (ICU), clearly shows increasing hazard up to day 13, then a decreasing hazard. The results clearly demonstrate that the hazard is not constant and provide a useful quantification of the effect of length of stay on the risk of MRSA colonization which provides useful insight.

  9. Tailoring the field and indication of adjuvant pelvic radiation for patients with FIGO stage Ib lymph nodes-negative cervical carcinoma following radical surgery based on the GOG score--a pilot study
    Rushdan MN, Tay EH, Khoo-Tan HS, Lee KM, Low JH, Ho TH, et al.
    Ann Acad Med Singap, 2004 Jul;33(4):467-72.
    PMID: 15329758
    INTRODUCTION: The traditional indications for adjuvant pelvic radiotherapy (RT) for International Federation of Obstetrics and Gynecology (FIGO) stage Ib1 lymph nodes-negative cervix carcinoma following radical surgery based on histopathological factors, such as deep stromal invasion and lymphovascular space invasion (LVSI), were often inconsistently applied. The perceived risk of relapse was subjectively determined. This pilot study attempts to determine if the treatment outcome will be affected when the indication for RT is based on the Gynecologic Oncology Group (GOG) Risk Score (RS) and the field of adjuvant RT is tailored to the RS.

    MATERIALS AND METHODS: From 1997 to 1999, 55 patients with FIGO stage Ib1 lymph nodes-negative cervical carcinoma limited to the cervix were prescribed RT following radical surgery, based on their RS, as follows: RS <40, RT is omitted; RS >40 to <120, modified (smaller) field RT; and RS >120, standard field pelvic RT. Their incidence and site of recurrence were compared with a similar cohort of 40 patients who were treated prior to 1997.

    RESULTS: Prior to 1997, of the 40 patients, 10 patients were given standard field RT. There were 2 (5%) recurrent diseases. The mean duration of follow-up was 61.6 months (range, 1 to 103 months). The RS of 23 of the 30 patients who were not given RT were available. The mean RS was 22 with 5 patients having a score of >40. From 1997 onwards, of the 55 patients, 28 (51%) did not require RT, 13 (23%) were treated with modified (smaller) field RT and 14 (26%) were given standard field RT. There were 2 (3.6%) cases of relapse. The mean duration of follow-up was 36.4 months (range, 5 to 60 months). All patients with a RS of <40 did not suffer any relapse. Their survival outcomes were better when compared to patients who did not have any RT in the GOG Study.

    CONCLUSIONS: The results of this study indicated that postoperative adjuvant RT given to patients with a high GOG RS of >120, significantly improved their 5-year recurrence rate and disease-free survival, as compared with the similar group of patients who were without adjuvant therapy in the GOG study. Patients with a GOG risk-score of <40 may be safely spared from adjuvant pelvic RT. The current treatment protocol did not compromise the outcome in patients, compared with the use of a less precise treatment protocol in the past.

  11. Cardiorespiratory hospitalizations associated with smoke exposure during the 1997, Southeast Asian forest fires
    Mott JA, Mannino DM, Alverson CJ, Kiyu A, Hashim J, Lee T, et al.
    Int J Hyg Environ Health, 2005;208(1-2):75-85.
    PMID: 15881981 DOI: 10.1016/j.ijheh.2005.01.018
    We investigated the cardiorespiratory health effects of smoke exposure from the 1997 Southeast Asian Forest Fires among persons who were hospitalized in the region of Kuching, Malaysia. We selected admissions to seven hospitals in the Kuching region from a database of all hospital admissions in the state of Sarawak during January 1, 1995 and December 31, 1998. For several cardiorespiratory disease classifications we used Holt-Winters time-series analyses to determine whether the total number of monthly hospitalizations during the forest fire period (August 1 to October 31, 1997), or post-fire period (November 1, 1997 to December 31, 1997) exceeded forecasted estimates established from a historical baseline period of January 1, 1995 to July 31, 1997. We also identified age-specific cohorts of persons whose members were admitted for specific cardiorespiratory problems during January 1 to July 31 of each year (1995--1997). We compared Kaplan-Meier survival curves of time to first readmission for the 1997 cohorts (exposed to the forest fire smoke) with the survival curves for the 1995 and 1996 cohorts (not exposed, pre-fire cohorts). The time-series analyses indicated that statistically significant fire-related increases were observed in respiratory hospitalizations, specifically those for chronic obstructive pulmonary disease (COPD) and asthma. The survival analyses indicated that persons over age 65 years with previous hospital admissions for any cause (chi2(1df) = 5.98, p = 0.015), any cardiorespiratory disease (chi2(1df) = 5.3, p = 0.02), any respiratory disease (chi2(1df) = 7.8, p = 0.005), or COPD (chi2(1df) = 3.9, p = 0.047), were significantly more likely to be rehospitalized during the follow-up period in 1997 than during the follow-up periods in the pre-fire years of 1995 or 1996. The survival functions of the exposed cohorts resumed similar trajectories to unexposed cohorts during the post-fire period of November 1, 1997 to December 31, 1998. Communities exposed to forest fire smoke during the Southeast Asian forest fires of 1997 experienced short-term increases in cardiorespiratory hospitalizations. When an air quality emergency is anticipated, persons over age 65 with histories of respiratory hospitalizations should be preidentified from existing hospitalization records and given priority access to interventions.

  12. Human enterovirus 71 subgenotype B3 lacks coxsackievirus A16-like neurovirulence in mice infection
    Chan YF, AbuBakar S
    Virol J, 2005;2:74.
    PMID: 16122396
    At least three different EV-71 subgenotypes were identified from an outbreak in Malaysia in 1998. The subgenotypes C2 and B4 were associated with the severe and fatal infections, whereas the B3 virus was associated with mild to subclinical infections. The B3 virus genome sequences had >= 85% similarity at the 3' end to CV-A16. This offers opportunities to examine if there are characteristic similarities and differences in virulence between CV-A16, EV-71 B3 and EV-71 B4 and to determine if the presence of the CV-A16-liked genes in EV-71 B3 would also confer the virus with a CV-A16-liked neurovirulence in mice model infection.

    Tetanus is still widely prevalent in many parts of the world especially in the developing countries. This study was conducted to assess the demographic and clinical features, treatment and outcome of tetanus in adults with a special emphasis on identification of predictors of mortality. This was a retrospective study of all adult patients admitted with tetanus over a three-year period from 1998 to 2000 at Lok Nayak Hospital, New Delhi, India. The demography, clinical features, treatment and complications of the patients were assessed and were evaluated against two possible outcomes- survival or death, to identify the predictors of mortality. There were 217 adults (148 males, 69 females) admitted with generalized tetanus during the study period. The mean age of the patients was 36.08 +/- 18.84 years. In most instances (63.5%), wounds / injuries served as the source of infection. Overall 31.8% had mild, 21.7% had moderate and 46.5% had severe disease at presentation. Respiratory failure and dysautonomia were the frequently observed complications. Of the 217 patients, 82 died - a mortality rate of 37.78%. Parameters that were significantly associated with increased mortality were: age (especially > 60 years); shorter duration of symptoms - trismus, rigidity and dysphagia; severe disease at presentation and shorter period of onset. Tetanus is a preventable disease associated with a high fatality rate. Universal coverage of immunization programme and appropriate wound prophylaxis is the corner stone of tetanus eradication. The treatment of tetanus is difficult and requires specialized and intensive care. The presence of parameters indicating an adverse outcome at the beginning in the patients will help identify the subset of patients that need more intensive management especially in resource poor nations.

    Sepsis is characterized by an uncontrolled release of pro-inflammatory and anti-inflammatory mediators leading to immunoparalysis, cellular and humoral dysfunction, multiorgan dysfunction and death. This study evaluated the efficacy of high-volume haemofiltration (HVHF) compared with continuous venovenous haemofiltration (CVVH) in removing these inflammatory mediators. Clinical responses were assessed with the sequential organ failure assessment (SOFA) score.

  17. Ethnicity modifies the association between diabetes mellitus and ischaemic heart disease in Chinese, Malays and Asian Indians living in Singapore
    Yeo KK, Tai BC, Heng D, Lee JM, Ma S, Hughes K, et al.

    PMID: 17021918 DOI: 10.1007/s00125-006-0469-z
    AIMS/HYPOTHESIS: The aim of the study was to determine whether the risk of ischaemic heart disease (IHD) associated with diabetes mellitus differs between ethnic groups.

    METHODS: Registry linkage was used to identify IHD events in 5707 Chinese, Malay and Asian Indian participants from three cross-sectional studies conducted in Singapore between the years 1984 and 1995. The study provided a median of 10.2 years of follow-up with 240 IHD events experienced. We assessed the interaction between diabetes mellitus and ethnicity in relation to the risk of IHD events using Cox proportional hazards regression.

    RESULTS: Diabetes mellitus was more common in Asian Indians. Furthermore, diabetes mellitus was associated with a greater risk of IHD in Asian Indians. The hazard ratio when comparing diabetes mellitus with non-diabetes mellitus was 6.41 (95% CI 5.77-7.12) in Asian Indians and 3.07 (95% CI 1.86-5.06) in Chinese (p = 0.009 for interaction). Differences in the levels of established IHD risk factors among diabetics from the three ethnic groups did not appear to explain the differences in IHD risk.

    CONCLUSIONS/INTERPRETATION: Asian Indians are more susceptible to the development of diabetes mellitus than Chinese and Malays. When Asian Indians do develop diabetes mellitus, the risk of IHD is higher than for Chinese and Malays. Consequently, the prevention of diabetes mellitus amongst this ethnic group is particularly important for the prevention of IHD in Asia, especially given the size of the population at risk. Elucidation of the reasons for these ethnic differences may help us understand the pathogenesis of IHD in those with diabetes mellitus.

    PMID: 16629515
    Breast cancer is the most common female cancer and the commonest cause of death due to cancer for women in Malaysia. This study was performed to identify the relationship with lifestyle factors. A case-control study was conducted among females with breast cancer who came for treatment to the Breast Clinic Hospital Kuala Lumpur in July until September 2004. A total of 203 female patients were recruited as cases along with 203 patients who attended the Outpatient Clinic, Hospital Kuala Lumpur during the study period as the controls. The study showed women who did not exercise regularly to have four times higher risk (adjusted odds ratio is 3.49, 95% CI is 1.84 to 6.62) compared to those who exercised regularly. Women with a high fat diet were also at elevated risk (adjusted odds ratio 3.84, 95% CI is 1.20 to 12.34) compared to those consuming a low fat diet. Women without breast cancer generally had a longer duration of lifetime lactation with a median of thirty-three months compared to women with breast cancer (twenty months, p<0.05). Women who did not take oral contraceptive pills but had breast-fed their child have a 56.0% lower risk (crude odds ratio 0.44, CI is 0.22 to 0.87) compared to women who did not take oral contraceptive pill and also did not breast-feed their child. If they had breast fed for thirteen months and above, they faced a 61.0% lower risk (crude odds ratio 0.39, 95% CI is 0.17 to 0.87). There was a significant inverse trend for lifetime lactation and breast cancer risk. In conclusion certain life styles of women are associated with a higher risk of breast cancer development. Therefore, the promotion of a healthy life style should be emphasized.

  19. Burkholderia pseudomallei animal and human isolates from Malaysia exhibit different phenotypic characteristics
    Lee SH, Chong CE, Lim BS, Chai SJ, Sam KK, Mohamed R, et al.
    Diagn Microbiol Infect Dis, 2007 Jul;58(3):263-70.
    PMID: 17350202
    Burkholderia pseudomallei is a Gram-negative saprophytic soil bacterium, which is the etiologic agent of melioidosis, a severe and fatal infectious disease occurring in human and animals. Distinct clinical and animal isolates have been shown to exhibit differences in phenotypic trait such as growth rate, colony morphology, antimicrobial resistance, and virulence. This study was carried out to gain insight into the intrinsic differences between 4 clinical and 6 animal B. pseudomallei isolates from Malaysia. The 16S rRNA-encoding genes from these 10 isolates of B. pseudomallei were sequenced to confirm the identity of these isolates along with the avirulent Burkholderia thailandensis. The nucleotide sequences indicated that the 16S rRNA-encoding genes among the 10 B. pseudomallei isolates were identical to each other. However, the nucleotide sequence differences in the 16S rRNA-encoding genes appeared to be B. pseudomallei and B. thailandensis specific. The growth rate of all B. pseudomallei isolates was determined by generating growth curves at 37 degrees C for 72 h. The isolates were found to differ in growth rates with doubling time varying from 1.5 to 2.3 h. In addition, the B. pseudomallei isolates exhibited considerable variation in colony morphology when grown on Ashdown media, brain-heart infusion agar, and Luria-Bertani agar over 9 days of observation. Antimicrobial susceptibility tests indicated that 80% of the isolates examined were Amp(R) Cb(R) Kn(R) Gm(R) Chl(S) Te(S). Virulence of the B. pseudomallei clinical and animal isolates was evaluated in B. pseudomallei-susceptible BALB/c mice. Most of the clinical isolates were highly virulent. However, virulence did not correlate with isolate origin since 2 of the animal isolates were also highly virulent.
