    Transfusion is an irreversible event which carries potential benefits as well as risk to the recipient. The objective of this study was to analyse all reported transfusion reactions of the year 2008 in the Blood Bank Unit of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). This is a retrospective study that was carried out by retrieving data from the laboratory information system. A total of 27842 transfusions were documented and the total reported transfusion reactions were 149. The incidence of transfusion reaction was 1 in 187 of all transfusions (0.54%); in which 69 (0.25%) were allergic in nature and 61 (0.22%) were febrile non-haemolytic transfusion reactions (FNHTR). Hypotensive reactions were identified in 6 (0.02%) patients. There were 9 (0.03%) cases reported with haemoglobinuria where no serological evidence of haemolytic transfusion reaction (HTR) was found. One HTR (0.003%) was identified and this was due to an error in patient identification in the ward. Other specified reactions like transfusion-related acute lung injury (TRALI), bacterial infections, Graft verses host disease (GVHD) were not reported. The highest frequency of the reactions occurred in the red cell transfusions which accounted for 111 cases. In conclusion, the incidences of transfusion reactions are low when compared to those reported by other centres.

    Ther Apher, 2001 Apr;5(2):147-9.
    PMID: 11354300
    Over the past 3 decades, plasmapheresis has been used more extensively for a variety of neurological and hematological disorders. We undertook a retrospective review to ascertain its safety, efficacy, and factor(s) that predispose to poor outcome. We reviewed 117 plasma exchanges in 24 patients with a mean age of 43 +/- 15 years; half were male. A total of 79% of the patients had neurological diseases, and the most common were chronic inflammatory demyelinating polyneuropathy, Guillain-Barré syndrome, and myasthenic crisis. Plasmapheresis was effective in 79% of the patients, especially for neurological indications. Complications occurred in 23% of the exchanges affecting 58% of the patients. Most complications were mild; sepsis was the most common (9.4% of exchanges), especially catheter related sepsis (6%), rash (4.3%), and hypotension (4.3%). Only 2 (8%) patients had severe complications that required mechanical ventilation. There were 5 mortalities (21%), 3 due to sepsis and 2 due to myocardial ischemia and arrhythmia, none of which occurred within 48 h of the last exchange. Patients with poor renal function had higher mortality. Overall, our figures agree with those from other institutions and indicate that plasma exchange is an effective and safe procedure, especially for a variety of neuroimmunological conditions.

    PMID: 12733163
    This is the first review on orthognathic surgery in Malaysia. The records of a total of 84 patients seen between 1977 and 1999 in the Department of Oral and Maxillofacial Surgery of the Faculty of Dentistry, University of Malaya were analysed. Skeletal III deformity formed 85% of the sample with a female dominance of 2 to 1. The patients' age ranged from 17 to 36 years, with a mean of 25.3 years. The common surgical techniques used were combined bilateral sagittal split and Le Fort I osteotomy. The predominant ethnic group was Chinese (n = 58, 69%); followed by Malay (n = 14, 17%) and Indian (n = 12, 14%).

    Jamaliah R, Fathilah J
    Med J Malaysia, 2002 Dec;57(4):390-7.
    PMID: 12733162
    Two hundred outpatients (115 females and 85 males) attending the University Malaya Medical Center (UMMC) eye clinic, aged 20 years and above and without any ocular surface disorder were recruited for this study. Their tear film status was determined subjectively by their symptoms and quantitatively by the cotton thread test, Schirmer's test, marginal tear film meniscus assessment, fluorescein corneal staining and tear break-up time. Dry eye was considered present if at least one symptom was experienced often or always, within the past 3 months. Dry eye was also considered present if one of these tests was positive; Schirmer's test < 5 mm, Phenol red thread (PRT) test < 10 mm and tear film breakup time (BUT) < 8 seconds. The prevalence of dry eye in this sample population as defined by presence of symptoms and an abnormal test result is 14.5%. Presence of dry eye as detected by clinical testing is higher in the Chinese race (p < 0.01), in the group 40-59 years (p = 0.024). There is no difference between females and males. A lower BUT score was more strongly associated with presence of dry eye symptoms (p = 0.02). Elderly patients have a lower BUT and Schirmer's score. There is lack of agreement between PRT and Schirmer's test, although both are measures of tear quantity.

    The prevalence of HFMD as well as the causative agents was unknown in peninsular Malaysia prior to May 1997. From May 1997 to June 2001, 585 patients suspected to have enterovirus infections, with 467 patients clinically diagnosed as having HFMD, were investigated in the diagnostic virology unit of the University Malaya Medical Centre. Data from this study showed that HFMD is endemic in Malaysia with the occurrence of two outbreaks during the study period. In each outbreak, a number of viruses were isolated but enterovirus 71 was the main virus isolated in both outbreaks. Echovirus 7 (Eo7) was isolated from 5 patients with HFMD in the second outbreak, a clinical entity that has not been attributed to it previously. Children aged 4 years and below, particularly those between 1 and 2 years of age, were in the main group of patients affected by the illness. HFMD by itself and without neurological involvement was relatively benign and self-limiting. There was no significant difference in the virus isolation rate with respect to gender and ethnic groups. Virus isolation was attempted in a total of 764 clinical specimens consisting of 342 stool specimens, 285 oral secretions specimens and 137 vesicular fluid specimens. Oral specimens gave the highest virus isolation rate (33.3%) followed by vesicular specimens (27.0%). Stool specimens only yielded an isolation rate of 14.0%.

    Between January 1994 to December 1998, 133 patients had a meniscal surgery at University Malaya Medical Centre. Fifty-four patients were assessed and scored with the Lysholm and Tegner scoring system. Twenty-nine patients had partial meniscectomies and 25 had meniscus repair. The outcome was successful in 80% with meniscal repair and 51.7% with partial meniscectomy. The outcome of meniscal repair in this study is comparable to other reported series. However, the failure rate for partial meniscectomy was high.

    Soong TK, Koh A, Subrayan V, Loo AV
    Graefes Arch Clin Exp Ophthalmol, 2011 Dec;249(12):1755-60.
    PMID: 20607549 DOI: 10.1007/s00417-010-1444-4
    PURPOSE: To describe the epidemiology of ocular injuries presenting to the University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia.

    DESIGN: Prospective analysis of all ocular trauma injuries presenting to the Department of Ophthalmology in UMMC from 1 January 2008 to 31 December 2008.

    PARTICIPANTS: A total of 603 eyes of 546 patients were recruited for the study.

    METHODS: All patients presenting to the department with ocular trauma injuries were assessed by an ophthalmologist. Data on the type and source of injury, demographic profile of the patients, and clinical presentation were documented using a uniform and validated datasheet.

    RESULTS: Among eye injury cases, 481 patients (88.1%) were male, with a male-to-female ratio of 7.4:1. Of the patients, 412 (75.5%) were Malaysian while the remaining 134 (24.5%) were of non-Malaysian nationality. The average age was 31.5 years (range 1-81 years). A total of 238 injured eyes (43.6%) were work-related. The common sources of eye trauma include the use of high-powered tools (30.8%), motor vehicle accident (23.1%), and domestic accidents (17.7%). Only six patients (2.5%) reported to having used eye protective device (EPD) at time of their work-related injuries.

    CONCLUSIONS: A major cause of preventable ocular injuries in Malaysia was work-related trauma. Ocular injuries can be reduced by the use of eye protection devices and the implementation of appropriate preventive strategies to address each risk factor. Effective training is an integral part of occupational safety and health, which should be made mandatory at the workplace. In addition, there should be a continual assessment of safety and health issues at the workplace. A long-term database of all ocular injuries in Malaysia is recommended, to aid research on a larger scale and the development of new preventive strategies for ocular injuries.

    Malaysia like many other countries worldwide uses spontaneous reporting systems as a mean of collecting data on suspected adverse drug reaction (ADR). However, compared to other countries, which use the system, the reporting rate in Malaysia is very low. Why some physicians do not report ADRs is not well understood.

  11. Fulltext Prevalence and association of pks+ Escherichia coli with colorectal cancer in patients at the University Malaya Medical Centre, Malaysia
    Iyadorai T, Mariappan V, Vellasamy KM, Wanyiri JW, Roslani AC, Lee GK, et al.
    PLoS One, 2020;15(1):e0228217.
    PMID: 31990962 DOI: 10.1371/journal.pone.0228217
    Escherichia coli (E. coli) from the B2 phylogenetic group is implicated in colorectal cancer (CRC) as it possesses a genomic island, termed polyketide synthetase (pks), which codes for the synthesis of colibactin, a genotoxin that induces DNA damage, cell cycle arrest, mutations and chromosomal instability in eukaryotic cells. The aim of this study was to detect and compare the prevalence of E. coli expressing pks (pks+ E. coli) in CRC patients and healthy controls followed by investigating the virulence triggered by pks+ E. coli using an in-vitro model. Mucosal colon tissues were collected and processed to determine the presence of pks+ E. coli. Thereafter, primary colon epithelial (PCE) and colorectal carcinoma (HCT116) cell lines were used to detect cytopathic response to the isolated pks+ E. coli strains. Our results showed 16.7% and 4.3% of CRC and healthy controls, respectively were pks+ E. coli. Further, PCE displayed syncytia and cell swelling and HCT116 cells, megalocytosis, in response to treatment with the isolated pks+ E. coli strains. In conclusion, pks+ E. coli was more often isolated from tissue of CRC patients compared to healthy individuals, and our in-vitro assays suggest these isolated strains may be involved in the initiation and development of CRC.

    PMID: 25631896
    INTRODUCTION: Morbidity and mortality from malignant diseases are usually the result of metastasis. The bone is the third most common site of metastasis.

    METHODS: This is a retrospective study of patients with metastatic bone disease who were referred to the Orthopaedic Department of University Malaya Medical Centre, Malaysia, between January 2004 and October 2009.

    RESULTS: A total of 151 patients (51.0% men, 49.0% women) had metastatic bone disease, with the highest incidence at the age range of 50-59 years. The commonest primary cancer was breast (23.3%), followed by lung (21.2%), prostate (9.3%), thyroid (7.3%) and renal cell carcinoma (5.3%); unknown primary cancer was 6.6%. There was long bone involvement in 52.7% of cases, axial bone in 44.5%, and both long and axial bones in 2.8%. The majority (90.1%) were symptomatic, with pain as the commonest symptom. 106 (70.2%) patients had pathological fractures. Neurological deficit was reported in 90.7% of patients, with 41.1% having extraskeletal metastases. 67.8% of the lesions were osteolytic, 24.3% were sclerotic, and 7.9%, mixed. Palliative and therapeutic interventions were undertaken for 62.0% of patients. The mean survival times were: breast 21.0; thyroid 20.7; prostate 20.3; lung 16.0; and unknown primary cancer 32.6 months.

    CONCLUSION: In our study, breast and lung cancers were the commonest primary cancers in metastatic bone disease. Most patients had more than one site of involvement, pain at presentation and pathological fractures. Surgery is beneficial to relieve pain and improve function and neurology. Duration of survival depends on the type of primary cancer and whether systemic metastasis is present.

    This retrospective study was conducted among 59 HIV/AIDS patients with opportunistic infections admitted to the University Malaya Medical Centre between 2000 and 2009. Fifty-five point nine percent of cases were Chinese, 25.4% were Malays, 11.9% were Indians and 6.8% were of unknown ethnic origin. The male:female ratio was 2.9:1 (44 males and 15 females). The highest prevalence (38.9%) occurred in the 30-39 year old age group. Men comprised 47.7% and women 53.3%; the majority of both were married. The majority of cases were Malaysians (89.8%) and the rest (10.2%) were immigrants. Most of the patients (18.6%) were non-laborers, followed by laborers (11.9%), the unemployed (5.1%) and housewives (3.4%). The most common risk factor was unprotected sexual activity (20.3%). The two most common HIV/AIDS related opportunistic infections were Pneumocystis carinii (jirovecii) pneumonia (PCP) (62.7%) and toxoplasmosis (28.8%). Seventy-two point nine percent of patients had a CD4 count <200 cells/microl and 5.1% had a CD4 count >500 cells/microl. Eleven point nine percent of cases died during study period. A low CD4 count had a greater association with opportunistic infections. Most of the patients presented with fever (44.1%), cough (42.4%) and shortness of breath (28.8%). Detection of the etiologic pathogens aids clinicians in choosing appropriate management strategies.

    Dayangku Norsuhazenah PS, Baki MM, Mohamad Yunus MR, Sabir Husin Athar PP, Abdullah S
    Ann Acad Med Singap, 2010 Jul;39(7):565-4.
    PMID: 20697675
    INTRODUCTION: In laryngectomised patients, tracheoesophageal speech is the gold standard for voice rehabilitation. This study evaluated complications related to the tracheoesophageal puncture (TEP) and the success rate in voice prosthesis after total laryngectomy at our institution over a 10-year period.

    MATERIALS AND METHODS: A retrospective review of 22 TEPs was performed between January 1998 and December 2008. The timing of TEP, type of voice prosthesis, surgical and prosthesis-related complications, and TEP closure were noted.

    RESULTS: Eighteen percent of the patients underwent primary and 82% secondary TEP. Our patients were predominantly males (95.4%) of Chinese descent with a mean age of 62.1 years. The types of voice prostheses used were ProvoxTM (n = 15), Voicemasters (n = 6), and Blom-Singer (n = 1). Prosthesis- related complications occurred in 77.3%. Notable complications were leakage (82.5%), prosthesis displacement (41.2%), intractable aspiration (29.4%), and aspiration of prosthesis (23.5%). The most common surgical-related complication was tracheostomal stenosis. An array of interventions comprising resizing or changing prosthesis type, nasogastric catheter insertion, stomaplasty, purse string suturing, and bronchoscopic removal of bronchial aspirated prosthesis were implemented to address encountered complications. In a mean follow-up of 34.8 months, 68.2% of patients achieved functional tracheoesophageal speech (75% of primary TEP and 67% of secondary TEP). There were 7 TEP closures indicated by persistent leakage, recurrent dislodgement, phonatory failure and, in 1 patient, persistent pain.

    CONCLUSIONS: TEP has become an integral part in the rehabilitation of a laryngectomee. However, management of the frequent complications related to TEP requires specific efforts and specialistic commitments in order to treat them.

    Background Drug-related problems are relatively common among hospitalised patients and may be detrimental to patients and even increase healthcare costs. Characterising drug-related problems allows remedial actions to be in place to minimise the frequency and ensure higher medication safety for the patients involved. Currently, the incidence of drug-related problems among hospitalised paediatric patients in Malaysia is unknown. Objective To determine the incidence, types and intervention acceptance, as well as the risk factors associated with drug-related problems in a Malaysian general paediatric ward. Setting General paediatric ward in Universiti Kebangsaan Malaysia Medical Centre. Method A cross-sectional observational study was conducted from March to May 2019. Data were collected from patients' medical charts, clinical notes and medical records for problem identification based on the modified Pharmaceutical Care Network Europe (PCNE) classification V 8.02. The incidence, types, causes and intervention acceptance as well as the risk factors were assessed. Main outcome measure Drug-related problems based on the modified PCNE classification V 8.02. Results In total, 225 paediatric patients with a total of 694 prescriptions were included in this study. The incidence of drug-related problems was 52.9% (198 prescriptions with problems in 119 patients). The main types of problems were treatment safety (68 prescriptions, 34.3%), incomplete prescription (56 prescriptions, 28.3%) and un-optimised drug treatment (35 prescriptions, 17.7%). The main causes for the problems were necessary information not provided (n = 63, 30.1%), inappropriate dose selection (n = 47, 22.5%) and medication served without a valid prescription (n = 40, 19.1%). Of the 143 interventions proposed to prescribers by the pharmacist, 117 (81.8%) were accepted. The number of prescriptions was found to be the only risk factor associated with DRPs (odds ratio, 1.91; 95% confidence interval, 1.54-2.38; p
