Lee WS, Veerasingam PD, Goh AY, Chua KB

J Paediatr Child Health, 2003 9 13;39(7):518-22.
PMID: 12969206

AIM: To determine the epidemiology of rotavirus gastroenteritis in children admitted to an urban hospital in a developing country from South-East Asia.
METHODS: Retrospective review of cases of acute gastroenteritis admitted to the children's ward of the University of Malaya Medical Centre, Kuala Lumpur, Malaysia, between 1996 and 1999.
RESULTS: During the study period, 333 cases (24%) of 1362 stool samples, obtained from children admitted with acute diarrhoea, were positive for rotavirus. Acute gastroenteritis constituted 8.2%, and rotavirus infection 1.6% of all the paediatric admissions each year. Of the 271 cases analysed, 72% of the affected population were less than 2 years of age. Peak incidence of admissions was between January to March, and September to October. Dehydration was common (92%) but electrolyte disturbances, lactose intolerance (5.2%), prolonged diarrhoea (2.6%) and cow's milk protein intolerance was uncommon. No deaths were recorded.
CONCLUSIONS: Rotavirus infection was a common cause of childhood diarrhoea that required hospital admission in an urban setting in Malaysia.

Malays J Pathol, 2004 Jun;26(1):35-41.
PMID: 16190105

It is well known that diagnostic accuracy of the clinical cause of death has not improved despite advances in diagnostic techniques. We aimed to investigate the accuracy of the clinical cause of death compared with the autopsy cause of death and to see if the Coroner's autopsy can play a role in clinical audit. Our study population consisted of all autopsies where the deceased was hospitalised or resuscitated at the Accident and Emergency Unit of the University of Malaya Medical Centre before death, performed during the period July 1998 to June 2000. The cases were subdivided according to natural and unnatural causes of deaths. Natural deaths were further subdivided in relation to the main organ systems involved while unnatural deaths were subcategorised into trauma, poisoning and burns. The rate of agreement between clinical and autopsy cause of death was further compared with duration of survival in the hospital. Of 132 autopsies included in this study, 115 were Coroner's autopsies. 78% of cases showed agreement between clinical and autopsy cause of death. The agreement rate in Coroner's cases was 80.0%. For natural and unnatural causes, the agreement rate was 56.7% and 84.3% respectively. There were 6 cases (4.5%) where an initial accurate diagnosis might have altered the prognosis of the deceased. In general, the rate of agreement increased with duration of survival of patients. However, this was no longer observed after a survival of more than 28 days. Our findings agree with other similar studies. The diagnostic accuracy of cause of death has not improved despite the modernisation in medical technology. The autopsy still plays an important role in clinical audit and medical education.

Mak KH, Kark JD, Chia KS, Sim LL, Foong BH, Ding ZP, et al.

Heart, 2004 Jun;90(6):621-6.
PMID: 15145860

OBJECTIVE: To determine the ethnic variation of short and long term female vulnerability after an acute coronary event in a population of Chinese, Indians, and Malays.
DESIGN: Population based registry.
PATIENTS: Residents of Singapore between the ages of 20-64 years with coronary events. Case identification and classification procedures were modified from the MONICA (monitoring trends and determinants in cardiovascular disease) project.
MAIN OUTCOME MEASURES: Adjusted 28 day case fatality and long term mortality.
RESULTS: From 1991 to 1999, there were 16 320 acute coronary events, including 3497 women. Age adjusted 28 day case fatality was greater in women (51.5% v 38.6%, p < 0.001), with a larger sex difference evident among younger Malay patients. This inequality between the sexes was observed in both the pre-hospitalisation and post-admission periods. Among hospitalised patients, women were older, were less likely to have suffered from a previous Q wave or anterior wall myocardial infarction, and had lower peak creatine kinase concentrations. Case fatality was higher among women, with adjusted hazard ratios of 1.64 (95% confidence interval (CI) 1.43 to 1.88) and 1.50 (95% CI 1.37 to 1.64) for 28 day and mean four year follow up periods. There were significant interactions of sex and age with ethnic group (p = 0.017). The adjusted hazards for mortality among Chinese, Indian, and Malay women versus men were 1.30, 1.71, and 1.96, respectively. The excess mortality among women diminished with age.
CONCLUSION: In this multiethnic population, both pre-hospitalisation and post-admission case fatality rates were substantially higher among women. The sex discrepancy in long term mortality was greatest among Malays and in the younger age groups.

Adult community-acquired pneumonia in Malaysia: prediction of mortality from severity assessment on admission

Loh LC, Khoo SK, Quah SY, Visvalingam V, Radhakrishnan A, Vijayasingham P, et al.

Respirology, 2004 Aug;9(3):379-86.
PMID: 15363012

Prediction of mortality in patients with community-acquired pneumonia (CAP) can be assessed using clinical severity scores on admission to hospital. The clinical benefit of such tools is untested in Asian countries. The aim of this study was to determine the early adverse prognostic factors in patients hospitalized with CAP in Malaysia and to assess the usefulness of the British Thoracic Society (BTS) severity criteria.

Risk of hospitalization for upper gastrointestinal tract complications associated with non-selective non-steroidal anti-inflammatory drugs in Malaysia: A retrospective case control study

Ong JSK, Menon SK, Kew ST, Menon J, Mavros P, Thong SP, et al.

APLAR Journal of Rheumatology, 2004;7(3):196-203.
DOI: 10.1111/j.1479-8077.2004.00094.x

Aims: To assess the association between non-steroidal anti-inflammatory drug (NSAID) use and upper gastrointestinal (GI) tract-related hospitalizations and to evaluate inpatient healthcare resource utilization associated with these complications in Malaysia.
Methods: A retrospective case control study was performed using medical records of patients admitted to two Malaysian hospitals during 1999 and 2000. Cases were identified based on mode of presentation at hospital admission. One control was identified for each case, matched by age, sex and admission date. NSAID exposure was determined by drug use during one year prior to admission. Conditional logistic regression analysis was used to determine the association between NSAID use and upper GI complications, adjusting for predictors.
Results: The 273 cases were significantly more likely to have used NSAIDs in the year prior to hospitalization than controls (27.8% vs. 6.2% of patients; P < 0.0001). Conditional logistic regression analysis adjusting for other predictors showed that the odds of being hospitalized for upper GI tract complications were 4.1 times higher among NSAID users than non-users (95% CI = 1.88-9.12). Other risk factors for GI-related hospitalizations were a history of upper GI tract complications (OR = 5.8, 95% CI = 1.28-26.53), use of gastroprotective agents (OR = 5.3, 95% CI = 1.67-16.79), and use of antacids (OR = 5.0, 95% CI = 2.10-11.91) in the previous year.
Conclusion: This study demonstrated that NSAID exposure was significantly higher among patients hospitalized for GI-related complications than for other reasons, indicating that NSAID use is an independent risk factor for upper GI tract complications in this Malaysian sample.

Molecular subtyping of clinical isolates of Candida albicans and identification of Candida dubliniensis Malaysia

Tay ST, Chai HC, Na SL, Ng KP

Mycopathologia, 2005 Apr;159(3):325-9.
PMID: 15883714

The genotypes of 221 recent isolates of Candida albicans from various clinical specimens of 213 patients admitted to the University Malaya Medical Centre, Malaysia was determined based on the amplification of a transposable intron region in the 25 S rRNA gene. The analyses of 178 C. albicans isolated from nonsterile clinical specimens showed that they could be classified into three genotypes: genotype A (138 isolates), genotype B (38 isolates) and genotype C (2 isolates). The genotyping of 43 clinical isolates from sterile specimens showed that they belonged to genotype A (29 isolates), genotype B (10 isolates), genotype C (2 isolates) and genotype D (2 isolates). The overall distribution of C. albicans genotypes in sterile and nonsterile specimens appeared similar, with genotype A being the most predominant type. This study reported the identification of C. dubliniensis (genotype D) in 2 HIV-negative patients with systemic candidiasis, which were missed by the routine mycological procedure. The study demonstrated the genetic diversity of clinical isolates of C. albicans in Malaysia.

Chandrasekaran PK, Jambunathan ST, Zainal NZ

Ann Gen Psychiatry, 2005 Apr 15;4(1):9.
PMID: 15876360

BACKGROUND: Organic Brain Syndromes (OBS) are often missed in clinical practice. Determining their varied presentations may help in earlier detection, better management, and, assessing prognosis and outcome. We described the in-patient referrals of patients suffering from the psychiatric effects of organic states and compared the symptomatology and mortality between those with the Acute and Chronic varieties. METHODS: 59 patients referred to our Consultation-Liaison (C-L) Psychiatry services and given a clinical diagnosis of OBS were selected over a 6-month period. Psychiatric and cognitive abnormalities and treatment regimes were recorded and fatality rates determined. Information regarding their condition 24 months after their index hospitalization was recorded. All data were entered into a proforma and analyzed after exclusion. RESULTS: The mean duration of detecting the symptoms by the physician was 3.52 days. The presence of a premorbid psychiatric illness had no influence on the clinical presentation but did on the mortality of patients with OBS (p = 0.029).Patients with the Acute syndrome had significantly more symptom resolution as compared to those with the Chronic syndrome (p = 0.001) but mortalityrates did not differ. Elderly patients and those with symptom resolution upon discharge did not show statistically significant higher mortality rates. The most popular combination of treatment was that of a low-dose neuroleptic and a benzodiazepine (34.7%). The need for maintenance treatment was not significantly different in any group, even in those with a past history of a functional disorder. CONCLUSION: Other than the Acute group having a significantly better outcome in terms of symptom resolution, our findings suggest that there was no significant difference in the clinical presentation between those with Acute or Chronic OBS. Mortality-wise, there was also no difference between the Acute and Chronic syndromes, nor was there any difference between the elderly and the younger group. There was also no significant difference in the need for continued treatment in both groups.

Lee WS, Hafeez A, Hassan H, Raja NS, Puthucheary SD

Southeast Asian J. Trop. Med. Public Health, 2005 May;36(3):678-82.
PMID: 16124437

A retrospective review of patients with focal non-typhoidal Salmonella (NTS) infection was performed to determine its features and outcome. All patients with focal NTS infection admitted to the University of Malaya Medical Center, Malaysia, from 1993 to 2002 were studied. More than half (58%) of the 35 cases (54% male, median age 39 years, range 1.5 months to 79 years) were immunocompromized or had chronic medical conditions. One-third of the patients (34%) had superficial infections (lymphadenitis or subcutaneous tissue infection) and all recovered with antimicrobial therapy alone. Deep infections (66%) noted were: meningitis (9%), osteomyelitis or arthritis (26%), abscesses of the gastrointestinal tract or adjacent organs (20%), and others (11%). Deep infections were more likely to occur in the extremes of age (<6 months or >60 years, p< 0.04), associated with adverse outcomes with an overall mortality rate of 9%, or required major surgery (15%).

Fulltext Symptomatology and health status in patients with chronic obstructive pulmonary disease

Loh LC, Lai CH, Liew OH, Siow YY

Med J Malaysia, 2005 Dec;60(5):570-7.
PMID: 16515107

Chronic Obstructive Pulmonary Disease (COPD) is a growing health problem worldwide and in Malaysia. Until recently, research on COPD has been slow and difficult, partly due to the huge heterogeneity of this disease, and its variable and imprecise definitions. To perform a descriptive study on a convenient sample of local patients with COPD treated in a state hospital in Malaysia. Fifty-two patients [mean (95% CI) age: 67 (63-70) years; 86% male: 38% Malays, 36% Chinese, 25% Indians; mean (95% CI) PEFR: 45 (40-51) % predicted normal] were interviewed. Clinico-demographic data was collected using a structured questionnaire and health-related quality of life was scored using St George's Respiratory Questionnaire (SGRQ). For analysis, patients were also divided into moderate (n=17) [PEFR 50% to 80%] and severe (n=35) [PEFR < 50%] disease groups. Except for education and total family income, demographic and comorbidity variables were comparable between the two groups of COPD severity. All except 9% of patients were current or ex-smokers. Breathlessness, not chronic bronchitis (i.e. cough and sputum), was the first ranking respiratory symptom in over 70% of the patients, whether currently or at early disease manifestation. Between 5 and 15% of the patients denied any symptom of chronic bronchitis as current or early stage symptoms. Duration of symptoms prior to the diagnosis varied considerably with about 9% having symptoms for over 10 years. Over 80% of the patients smoked for over 15 years before the onset of symptoms. Quality of life in patients with COPI) was generally poor and similar between both COPD severity groups. About one fifth of the patients had exacerbations more than 12 times a year. While many features described in our local patients are well recognized in COPD, the finding that 'chronic bronchitis' is not a prominent symptom in the current or past history may have important implications in the diagnosis of at risk individuals and patients with early disease requiring attention. More research is required to confirm and to understand this.

Fulltext Risk factors associated with incomplete immunisation in hospitalised infants

Norlijah O, Menon BS, Azlyna MYY

Med J Malaysia, 2005 Dec;60(5):563-9.
PMID: 16515106

To determine the immunisation status of hospitalised infants and to examine the potential risk factors associated with incomplete immunisation. Prospective study of infants admitted to a paediatric hospital in Kuala Lumpur, conducted by interviewing carers. Twenty-two percent of infants had incomplete immunisation. The most significant factor that was associated with incomplete immunisation was the carer's lack of knowledge on the timing of the next immunisation (p = 0.005). Other factors that had significant association were the presence of a previous admission to hospital (p = 0.03) and the infant's age of more than 6 months (p = 0.025). The rate of incomplete immunisation in the study population was 22%. An admission to hospital of an infant should be taken as an opportunity to update their immunisation in order to improve the rate of uptake.

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.

Term breech trial and its consequences on practice: a retrospective study of the University of Malaya Medical Centre's experience

Noor Azmi MA, Aniza A

JUMMEC, 2005;8:39-44.

To see the trend in managing singleton breech pregnancy after the term breech trial. Secondly to compare the safety of different modes of delivery for term, singleton breeches by looking at the immediate neonatal outcome, based on our own experience. Breech infants were identified by examining computer-stored maternal discharge records of hospitalization for the years 1990 and 2000 respectively. Parameters studied included planned mode of delivery, actual mode of delivery, parity, previous vaginal delivery, Apgar score at five minute, birth weight, referral to special care nursery and neonatal morbidity. Of 6,496 deliveries in 1990 and 5,081 in 2000, there were 220 (3.4%) and 148 (2.9%) term breech infants respectively, of which 115 (for 1990) and 102 (for 2000) case records were available. In 1990, 62.6% of the women had trial of vaginal breech delivery but only 24.5% of the women in 2000 were allowed to do so (p < 0.05). Caesarean section rate for singleton breeches increased from 51.3% in 1990 to 84.3% in 2000 (p < 0.05). Mean Apgar score at five minutes was significantly lower after vaginal breech delivery (9.40 ± 1.36) compared to after Caesarean section (9.72 ± 0.712) but there was no clinical significance. There was a noticeable trend towards Caesarean section and less trial of vaginal delivery. Neonatal outcomes of babies born abdominally were statistically better than those born vaginally but there was little clinical impact. Perhaps in properly selected cases, a planned vaginal breech delivery still has a role to play. KEYWORDS: Breech deliveries, Caesarean section, Apgar score

Kwek SK, Chew WM, Ong KC, Ng AW, Lee LS, Kaw G, et al.

J Psychosom Res, 2006 May;60(5):513-9.
PMID: 16650592

BACKGROUND: Little is known about the long-term consequence of severe acute respiratory syndrome (SARS). We carried out an assessment on SARS patients after their recovery from their acute illness.
METHOD: Postal survey comprising Health-Related Quality of Life (HRQoL) questionnaires and anxiety and depression measures was sent to them at 3 months' postdischarge.
RESULTS: There was a significant impairment in both the HRQoL and mental functioning. Forty-one percent had scores indicative of a posttraumatic stress disorder (PTSD); about 30% had likely anxiety and depression.
CONCLUSION: SARS has significant impact on HRQoL and psychological status at 3 months.

Fulltext Tubal Ectopic Pregnancy: Do Our Women Benefit From Laparoscopic Surgery?

Lim, K.J., Omar, M.H., Jamil, M.A., Ng, S.P.

International Medical Journal Malaysia, 2006;5(2):1-8.
MyJurnal

Introduction: Operative laparoscopy is the gold standard approach for treatment of tubal pregnancy. Although benefits of this approach are well established, data on its uptake trend in Malaysia is largely unknown. Objective: This study aims to determine the operative laparoscopy uptake in management of tubal pregnancy at a busy tertiary hospital and whether the benefits associated with laparoscopic surgery was achieved. Materials and Methods: This prospective observational study was conducted on all women admitted for tubal pregnancy at Hospital Sultanah Aminah, Johor Bahru, a public tertiary hospital over a period of 12 months. The on-call team was responsible for the surgical approach. Patient’s clinical presentation, operative laparoscopic uptake, factors affecting the choice of approach and duration of hospitalization were analyzed. Results: The tubal pregnancy rate was 7.6 per 1000 deliveries. Twenty- seven of the 138 cases (20%) had hypovolemic shock, requiring urgent laparotomy and were excluded from study. The operative laparoscopy rate for stable tubal pregnancy was only 42.3% (47 of 111 cases). Women managed laparoscopically were associated with a significantly higher pre-operative hemoglobin level, mostly nullipara and had surgery performed during office hours. They waited longer for their surgery but were discharged earlier compared to the laparotomy group. There was no difference in the duration of hospitalization. Conclusions: Less than half of all hemodynamically stable tubal pregnancies in our hospital had operative laparoscopy. The current laparoscopy uptake rate can be further improved.
