Introduction: Epilepsy is a neurological disease with high global prevalence. Almost one-third of epilepsy patients continue having seizures despite adequate treatment. Perampanel has been widely used in the Western countries as an adjunctive therapy for both generalized and focal seizures. Owing to its high cost, the use of perampanel is limited in our country., Materials and Methods: We conducted a descriptive, retrospective study among epilepsy patients treated with perampanel. We aimed to assess the efficacy and safety of perampanel as an adjunctive in our hospital., Results and Conclusions: From our cohort of 25 patients, most of the patients were either on one or three anti-seizure medications (ASMs) prior to initiation of perampanel. Perampanel was added in 88% of them due to persistent seizures. Twenty-two (88%) patients experienced reduction in seizure frequency. 12% experienced mild side effects, which were leg cramps, hyponatremia and drowsiness. Only 1 patient stopped perampanel due to its side effects., Conclusion: Perampanel is a well-tolerated ASM that should be widely used as an adjunctive. More studies with regards to its efficacy and safety involving more centres are encouraged in Malaysia.

Introduction: Healthcare drivers, including ambulance drivers, were less concerned about health and safety during the COVID-19 pandemic, with not only the risk of COVID-19 infection but also a higher risk of prolonged states of alertness, stress, burnout, fatigue and road traffic accident. This study aimed to determine the prevalence of stress and its associated factors among healthcare drivers, especially during the COVID-19 pandemic., Materials and Methods: This study employs a crosssectional study design and utilises self-reported data obtained from locally validated personal stress inventory questionnaires. The data collection period spanned from August 1 to 31, 2020. The study sample consisted of 163 healthcare drivers affiliated with the Negeri Sembilan State Health Department. The Chi-square test and Fisher's exact test were the first used to determine the association between variables prior to conducting multiple logistic regression to predict the relationship between dependent and independent variables., Results: In COVID-19's first year, 7.4% (n = 12) of healthcare drivers reported perceived stress with ambulance drivers reporting more stress (10.6%; n = 5) than non-ambulance drivers (6.0%; n = 7). Simple statistical analysis identified perceived stress significantly associated with household income, smoking status and performing on-call. Further analysis by multiple logistic regression found that perceived stress was significantly related to smoking (aOR 19.9, 95% CI: 1.86-213.90), and performing on-call (aOR 8.69, 95% CI 1.21-62.28). Nevertheless, no association was found between perceived stress and age, ethnicity, marital status, education, household income, co-morbidities, driving assignment, employment duration, needing a part-time job or motor vehicle accident history., Conclusion: The study found that the perceived stress amongst Malaysian healthcare drivers during the COVID-19 pandemic was relatively low. This could be due to fewer lifethreatening tasks, emergencies, assigned tasks and increase income due to overtime during the COVD-19 pandemic. The OSH team's efforts to provide consistent safety and health training, including stress management, may have contributed to the healthcare driver's ability to effectively manage the stressful circumstances encountered during the pandemic. In order to enhance salary competitiveness, employers should provide financial management education alongside subsidised housing and childcare provisions. Healthcare drivers who smoke should be taught different stress reduction techniques so that they can handle their stress in a healthy way.

Introduction: COVID-19 patients frequently demonstrate radiological organising pneumonia (OP) pattern. The longterm outcome and treatment options for this group of patients remain uncertain. We aim to describe the clinical and radiological outcomes of patients with COVID-19-related OP and identify possible clinical factors associated with inferior radiological outcome., Materials and Methods: Post-COVID-19 clinic attendees, consisting of post-COVID-19 patients discharged from major hospitals in the state of Selangor during the third pandemic wave of COVID-19 in Malaysia, were enrolled in this retrospective study for 6 months. Physician-scored Modified Medical Research Council (mMRC), patient self-reported quality of life (EQ-VAS) score and follow-up CT scan were evaluated., Results: Our cohort comprised 131 patients, with a median age of 52 (IQR 39-60) years and median BMI of 29.40 (IQR 25.59-34.72). Majority (72.5%) had co-morbidities, and 97.7% had severe disease requiring supplementary oxygen support during the acute COVID-19 episode. 56.5% required intensive care; among which one-third were invasively ventilated. Median equivalent dose of methylprednisolone prescribed was 2.60 (IQR 1.29-5.18) mg/kg during admission, while the median prednisolone dose upon discharge was 0.64 (IQR 0.51-0.78) mg/kg. It was tapered over a median of 8.0 (IQR 5.8-9.0) weeks. Upon follow-up at 11 (IQR 8-15) weeks, one-third of patients remained symptomatic, with cough, fatigue and dyspnoea being the most reported symptoms. mMRC and EQ-VAS scores improved significantly (p<0.001) during follow-up. Repeat CT scans were done in 59.5% of patients, with 94.8% of them demonstrating improvement. In fact, 51.7% had complete radiological resolution. Intensive care admission and mechanical ventilation are among the factors which were associated with poorer radiological outcomes, p<0.05., Conclusion: Approximately one-third of patients with SARSCoV- 2-related OP remained symptomatic at 3 months of follow-up. Majority demonstrated favourable radiological outcomes at 5-month reassessment, except those who required intensive care unit admission and mechanical ventilation.

Introduction: In the past decades, water-related disasters had been accounted for about three-quarters of all-natural disasters worldwide. Asia is the most affected region with more than 45% of fatalities and more than 90% of the victims affected by aquatic disasters. Aquatic events progress differently and rapidly as compared to inland disasters. Thus, apart from additional equipments and trained aquatic rescuers, aquatic disaster operation requires specific strategies and tactics., Materials and Methods: This qualitative study was conducted using mixed methods involving the Delphi method and decision-conferencing approach. Two rounds of open-ended questionnaires were sent to subject matter experts from rescue agencies that involved in aquatic disaster rescue and management. Feedback from the panel was reviewed, the natural history of different aquatic disasters was appraised, and the decision-analysis model on the command, control and management of aquatic disaster was developed. The model was then reassessed through an iteration process at decision-conferencing among the expert panel until the final framework was accepted by all members of the panel., Results: The fast progression of aquatic disasters with multiple hazards on the scene and unique technical challenges of the operation increase the risk of rescuers to become victims themselves. The developed conceptual framework, namely Aquatic Disaster Activation Plan and Tactic (ADAPT), was found able to guide rescuers in risk assessment, judgment, and response in aquatic disasters based on strategies and tactics for different phases along the natural history of aquatic disasters., Conclusion: With realistic scenario-based training and drills, ADAPT can be the blueprint in aquatic disaster management. It is designed to facilitate rescue agencies and organizations in preparing and executing the technical aquatic rescue operations safely, according to the resources available and the capability of the respective rescue organization.

Introduction: Achalasia cardia is an oesophageal motility disorder that affects various age groups. This study focused on the epidemiological features of achalasia, its risk factors, treatment modalities offered and the clinical outcomes in a tertiary hospital., Materials and Methods: A retrospective search was carried out on all patients with a diagnosis of achalasia cardia in Hospital Tuanku Ja'afar (HTJ), Seremban, Malaysia between 2014 and 2018. Demographic data, patient symptomatology, and definitive management options were determined from the records. Telephone interviews were conducted to evaluate patient satisfaction with the outcome of treatment., Results: There were 30 patients with a newly diagnosed achalasia cardia in that 5-year period, with an equal incidence among men and women. The mean age of presentation was 44.63 ± 18.21 years. Malays formed the largest group. The mean weight and body mass index were 46.8 ± 10.4 kg and 18.0 ± 4.4 kg/m2 respectively. There was a wide range of duration of symptoms at presentation with a mean of 30.11 ± 35.29 months. Almost all patients presented with dysphagia (96.7%) while 70% also noted loss of weight. All patients underwent oesophagogastroduodenoscopy (OGDS) and 26 patients (86.7%) had barium swallow as part of diagnostic workup. A total of 18 patients underwent a laparoscopic Heller myotomy with or without Dor Fundoplication and/or cruroplasty while two patients (6.7%) underwent pneumatic dilatation as first treatment. Iatrogenic mucosal perforations were detected in 8 patients who underwent myotomy and fundoplication and were repaired intraoperatively. Of the patients who underwent myotomy and fundoplication, the mean weight increase was 15.6kg, increasing from 43.0 ± 8.4 kg to 58.6 ± 13.7 kg. All the patients who underwent treatment were satisfied with their treatment outcomes., Conclusion: Most patients with achalasia cardia deemed suitable for surgery and counselled accordingly accept surgery resulting in high levels of satisfaction and weight gain in almost all these patients. A small minority who opt for pneumatic dilatation may also achieve satisfactory outcomes comparable to surgery in the short term. Although rare, clinicians should be able to recognise this disease early as early intervention often leads to satisfactory longterm outcomes.

Introduction: Despite the ever-growing number of community onset (CO) Pseudomonas aeruginosa (P. aeruginosa) bacteraemia, there is a dearth of district hospital-based research examining this significant infection, which is associated with high mortality. The objectives of this study were as following: (1) to determine the risk factors of CO P. aeruginosa bacteraemia, (2) to compare the 30-day mortality rate between P. aeruginosa and Escherichia coli bacteraemia and (3) to identify the predictors of 30-day mortality for CO gram negative bacteraemia., Methods: This is a retrospective case control study in Hospital Seri Manjung and Hospital Teluk Intan, Perak, Malaysia. P. aeruginosa bacteraemia cases that occurred between 1st January 2015 to 31st December 2019 were included, whilst E. coli bacteraemia cases that occurred within the same period were recruited successively until 1:2 case control ratio was achieved. Subjects below 12-year-old and those with polymicrobial bacteraemia were excluded. Demographic, clinical and treatment data were collected using pre-tested data collection forms by trained investigators., Results: A total of 61 patients with P. aeruginosa bacteraemia and 122 patients with E. coli bacteraemia were included. Recent admission in the earlier three months, regular haemodialysis, immunosuppressive therapy in the past 30 days, chronic wound/pressure sore at presentation and indwelling urinary catheter at presentation were identified as independent predictors of CO pseudomonal bacteraemia. Whilst older age was identified as a negative predictor of CO Pseudomonal bacteraemia (all p<0.05). The 30-day mortality rate was 34.4% in subjects with P. aeruginosa bacteraemia and 27.0% in those with E. coli bacteraemia (p=0.302). Predictors of 30-day mortality for community onset gram negative bacteraemia were as follow: older age, underlying solid tumours, neutropaenia at presentation, in-patient mechanical ventilation, and inpatient nasogastric tube insertion. Unexpectedly, receipt of inappropriate empirical antibiotics which was switched later (delayed and non-delayed switching) was identified as the negative predictors of mortality (all p<0.05)., Conclusion: It is prudent to restrict the usage of empirical anti-pseudomonal antibiotics among individuals at risk as liberal usage of broad-spectrum antibiotics engenders emergence of drug resistant organism, particularly in district setting where community onset pseudomonal bacteraemia remains scarce. Subjects with elevated risk of mortality should receive early escalation of care as per sepsis management guidelines.

Introduction: Stent thrombosis (ST) is an uncommon, but significant complication following angioplasty. We aimed to examine the predictors, clinical outcomes and mechanism of definite ST cases among patients who underwent percutaneous coronary intervention (PCI)., Methods: This was a retrospective observational registry of 14,935 patients from the year 2011 till 2015. Clinical characteristics, clinical outcome and intracoronary imaging data were recorded in all the patients. The SPSS Statistic version 24 was used for statistical analysis. The Cox regression hazard model was used to report calculate the hazard ratio (HR) with a 95% confidence interval (95%CI). Independent predictors of ST were identified by univariate logistic regression analysis. Variables that showed a statistically significant effect in univariate analyses were entered in a multivariate Cox proportional hazards model. A p-value<0.05 was regarded as significant., Results: The incidence of definite ST was 0.25% (37 out of 14935 patients). 75% of ST group patients presented with ST elevation myocardial infarction (75% vs. 19.8%, p<0.01). There was higher mortality among patients with ST when compared to the group without ST (Hazard Ratio, HR=10.69, 95%CI: 1.13, 100). Two independent predictors of ST were 1) previous history of acute myocardial infarction (HR=2.36, 95%CI: 1.19, 4.70) and 2) PCI in the context of acute coronary syndrome when compared to elective PCI (HR=37, 95%CI: 15.7, 91.5). Examination of 19 ST cases with intracoronary imaging identified nine cases (47%) of underexpanded stents and five cases (26%) of malopposition of stents., Conclusions: ST is associated with high mortality. PCI in acute coronary syndrome setting and a previous history of acute myocardial infarction were significant predictors for ST. Intracoronary imaging identified stent underexpansion and malopposition as common reasons for ST. In cases where the risk of ST is high, the use of intracoronary imaging guided PCI is recommended.

Chronic obstructive pulmonary disease (COPD) is a debilitating progressive lung disease characterised by irreversible airflow obstruction. In addition to an increase in morbidity and mortality, exacerbation also results in frequent hospital visits, which place a burden on healthcare systems. Non-invasive positive pressure ventilation (NPPV) with conventional inspiratory pressures is the standard ventilatory support for patients in exacerbation. At present, the use of higher inspiratory pressures through high intensity noninvasive positive pressure ventilation (Hi-NPPV) during an exacerbation remains unknown. We describe a novel application of Hi-NPPV in a patient with acute exacerbation who was refractory to conventional NPPV.

Background: Malaysia continues to have a very low cadaveric organ donation rate of 0.48 per million population. The aim of this paper is to assess the attitude, beliefs and knowledge of patients and relatives at three different hospitals in Negeri Sembilan towards organ donation to increase the acceptability of organ transplant., Methods: A cross-sectional descriptive study with convenient sampling was carried out Hospital Tuanku Ja'afar, Hospital Port Dickson and Hospital Tuanku Ampuan Najihah in Negeri Sembilan, Malaysia. The participants answered a questionnaire regarding the source of their information about organ donation, their knowledge about brain death and willingness to donate. The association between variables was tested using chi-squared test or Fischer's exact test as appropriate., Results: A total of 385 individuals completed the survey of whom 134 (35%) were willing to donate their organs upon death and 25(19%) were registered donors. Higher educational level (41%), age 30 and below (42%) and people who attended organ donation awareness campaigns (60%) were more willing to donate their organs. Correct understanding of brain death was associated with willingness to be an organ donor. The commonest reason cited for unwillingness to donate was opposition from family members., Conclusion: Marital status, religion, source of knowledge and occupation are significant factors in willingness to donate organs among Malaysians. Lower age and higher educational level were positive factors towards organ donation. Direct personal contact through awareness campaigns, family and friends has a potential for greater positive impact on organ donation.

Introduction: In the course of their undergraduate training at the International Medical University, students receive a Basic Trauma Life Support course., Objective: We wanted to test the long-term retention of knowledge (after 16 months) of third year medical students who had received training in Basic Trauma Life Support Method: To assess the retention of knowledge one cohort of students who received the training course were tested again 16 months later using the same 30 question One Best Answer quiz., Results: Seventy-three students who underwent the course sat for the Retention test. The number of students who passed the Retention test was not significantly different from the test taken immediately after the course. The mean scores, 62.5% and 59.5% respectively, were however significantly different., Conclusion: Our study involves a relatively long interval between the course and retention of knowledge test shows encouraging results.

Seventy-three articles related to metabolic syndrome were found in a search through databases dedicated to indexing all literature with original data involving the Malaysian population between years 2000 and 2015. Metabolic syndrome affects 25 to 40% of adult population of Malaysia with the risk increasing with age. Obese children are also at risk. Indian ethnicity has the highest rates, followed by Malay and chinese. It was found that socioeconomics determinants such as living in urban areas, unemployment, lower income, lower education level and shift workers had higher prevalence of metabolic syndrome. Metabolic syndrome is associated with other medical conditions like cardiovascular diseases, psychiatric disorders, erectile dysfunction, polycystic ovarian syndrome and colorectal cancer. Several biomarkers have been determined to be relevant to our local population but their usage in clinical setting needs further research. Literature into effectiveness of management of metabolic syndrome in Malaysia is lacking and the results were only modest. there are several diagnostic criteria available for metabolic syndrome internationally and their individual significant to our local population is not clear. It also makes it difficult to compare results between studies using different criteria. Finally, we could not identify any local study to look at the health economic burden of metabolic syndrome locally.

A literature search of articles as detailed in the paper Bibliography of clinical research in Malaysia: methods and brief results, using the MESH terms Obesity; Obesity, Abdominal; and Overweight; covering the years 2000 till 2015 was undertaken and 265 articles were identified. Serial population studies showed that the prevalence of obesity increased rapidly in Malaysia in the last decade of the twentieth century. This follows the rising availability of food per capita which had been begun two to three decades previously. Almost every birth cohort, even up to those in their seventh decade increased in prevalence of overweight and obesity between 1996 and 2006. However, the rise in prevalence in obesity appears to have plateaued after the first decade of the twentieth century. Women are more obese than men and Malays and Indians are more obese than Chinese. The Orang Asli (Aborigines) are the least obese ethnic group in Malaysia but that may change with socioeconomic development. Neither living in rural areas nor having low income protects against obesity. On the contrary, a tertiary education and an income over RM4,000/month is associated with less obesity. Malaysians are generally not physically active enough, in the modes of transportation they use and how they use their leisure time. Other criteria and measures of obesity have been investigated, such as the relevance of abdominal obesity, and the Asian criteria or Body Mass Index (BMI) cut-offs value of 23.0 kg/m 2 for overweight and 27.0 kg/m 2 for obesity, with the view that the risk of diabetes and other chronic diseases start to increase at lower values in Asians compared to Europeans. Nevertheless the standard World Health Organization (WHO) guidelines for obesity are still most widely used and hence is the best common reference. Guidelines for the management of obesity have been published and projects to combat obesity are being run. However, more effort needs to be invested. Studies on intervention programmes showed that weight loss is not easy to achieve nor maintain. Laboratory research worldwide has uncovered several genetic and biochemical markers associated with obesity. Similar studies in Malaysia have found some biomarkers with an association to obesity in the local population but none of great significance.

Anti-N-Methyl-D-Aspartate receptor (NMDAR) encephalitis is an immune mediated condition with characteristic clinical presentation. We report the first case from Borneo, Sabah and the use of electroconvulsive therapy (ECT) in treating recalcitrant psychiatrist symptoms associated with this condition.

Background: Eosinophilic gastroenteritis (EG) can mimic symptoms of common gastrointestinal (GI) disorders but responds well to appropriate treatment. Accurate diagnosis is central to effective management. Data on EG in Southeast Asia is lacking. We aim to describe the clinical profiles and treatment outcomes of adult patients with EG in a Singapore Tertiary Hospital., Materials and Methods: This retrospective study involved archival search of patients with GI biopsies that showed eosinophilic infiltration from January 2004 to December 2012. Patients' clinical data from computerised hospital records and clinical notes was reviewed. Diagnostic criteria for EG included presence of GI symptoms with more than 30 eosinophils/high power field on GI biopsies. Patients with secondary causes for eosinophilia were excluded., Results: Eighteen patients with EG were identified (mean age 52 years; male/female: 11/7). Fifteen patients (83%) had peripheral blood eosinophilia. Seven patients (39%) had atopic conditions. Most common symptoms were diarrhoea and abdominal pain. Small intestine was the most common site involved. Endoscopic finding was non-specific. Ten patients were treated with corticosteroids (nine prednisolone, one budesonide): eight patients (89%) responded clinically to prednisolone but four patients (50%) relapsed following tapering-off of prednisolone and required maintenance dose. One patient each responded to diet elimination and montelukast respectively. Half of the remaining six patients who were treated with proton-pump inhibitors, antispasmodic or antidiarrheal agents still remained symptomatic., Conclusion: Prednisolone is an effective treatment though relapses are common. Small intestine is most commonly involved. EG should be considered in the evaluation of unexplained chronic recurrent GI symptoms.

Hemobilia is a rare but potentially lethal condition. The commonest cause of hemobilia is trauma, accounting up to 85% of all cases. Hemobilia caused by gallstones is very rare. Most of the cases of hemobilia are either managed conservatively or treated by embolization. Surgery is indicated only when there is an associated surgical condition or when embolization fails. We report a case of a 72-year-old patient with massive hemobilia caused by gallstone erosion to the adjacent artery, diagnosed intraoperatively. The complication was successfully managed by cholecystectomy and repair of the bleeding vessel. This case highlights the importance that hemobilia should be suspected in patients presenting with upper gastrointestinal bleeding. Although rare, massive hemobilia can be life threatening, leading to significant morbidity and mortality. Therefore, a high index of suspicion and timely intervention are important.

105 articles related to colorectal cancer(CRC) were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. 56 articles were selected and reviewed on the basis of clinical relevance and future research implications. Research into the genetic basis for colorectal cancer included studies in germline mutations of known syndromes as well as polymorphisms that conferred individuals a higher odds ratio for developing CRC. Several studies also documented the variety of somatic mutations seen in cases of sporadic CRC in Malaysia. Studies into the knowledge and attitudes of Malaysians regarding CRC revealed poor appreciation of the common symptoms, risk factors and available measures for its early detection. This may explain the observed facts that more Malaysians present with late stage CRC than seen in developed countries. The small amount of data recorded concerning the outcome of treatment also suggests overall survival of Malaysian CRC patients for comparable stage of CRC is lower than achieved in developed countries.

Introduction: Spontaneous rupture is a dramatic presentation of HCC and it carries high mortality rate. To study the outcomes of ruptured HCC patients managed at a tertiary referral centre in Malaysia., Methods: A retrospective review of all ruptured HCC patients managed as inpatient at the Department of Hepatobiliary Surgery, Hospital Selayang between January 2001 and December 2010. Data was retrieved from the hospital electronic medical records, Powerchart (Cerner Corporation Inc., USA) and supplemented with registry from Interventional Radiology record of chemoembolization and registry from hepatobiliary operative surgery records., Results: There were 22 patients admitted with confirmed diagnosis of ruptured HCC over 10 years period. The common clinical findings on presentation were abdominal pain and presence of shock (36.4%). The mortality rate was 81.8% with only four patients noted to be alive during the follow up. One year overall survival for ER and DR are 40.0% and 72.7% respectively and the median survival in patients treated with DR was 433.3 days whereas it was 212.5 days in ER group., Conclusions: This study supports the clinical practice of TAE should be the first line treatment followed by staged surgery in suitable candidates with ruptured HCC.

The Malaysian National Cancer Registry (NCR) report for the period 2003-2005 shows an incidence of stomach cancer of 2.2 for Malay, 11.3 for Chinese and 11.9 for Indian males per 100,000 population. Malay (1.3), Chinese (7.2) and Indian (7.2) women have rates lower than men. Malays in Peninsular Malaysia have five times less stomach cancer than Chinese and Indians. This racial difference is more marked than that noted in the Singapore cancer registry. Regional data from Kelantan has an even lower rate for Malays there (1.5 for males and 0.9 for females per 100,000 population). The incidence of Helicobacter pylori infection, a known risk factor for stomach cancer, is low among Malays.

To report a case of methylene blue related endophthalmitis. Observational case report. Review of clinical record, photographs. A 60 year old man developed endophthalmitis after methylene blue was accidentally used to stain the anterior capsule during phacoemulsification of cataract. His left visual acuity deteriorated from 6/12 to 6/36 two weeks after the operation. Despite intensive treatment with topical and intravitreal antibiotics, his condition deteriorated. A vitrectomy and silicone oil injection eventually managed to control the progression of the disease and salvage the eye. However the visual outcome remained poor due to corneal decompensation and retinal ischemia. Both vitreous tap and vitreous biopsy were negative for any organism. Methylene blue is extremely toxic to ocular structures and should not be used intraocularly.

Six hundred and fifty-five central venous catheters (CVC) in 496 patients in the intensive care unit of Hospital Sultanah Aminah were studied to determine the incidence and risk factors for central venous catheter-related blood stream infection (CR-BSI). CR-BSI was diagnosed in 38 catheters, giving an incidence of 9.43 CR-BSI per 1000 catheter days. The mean duration in situ was 8.4 +/- 4.9 days for infected CVCs and 6.0 +/- 3.8 days for non infected CVCs (p = 0.001). CVCs inserted in ICU had the highest infection rate (9.4%) compared to those inserted in the operating theatre (1.4%) and ward (2.8%) (p = 0.001). The highest rate of CR-BSI occurred with 4-lumen catheters (usually inserted when patients needed total parenteral nutrition) with a percentage of 15.8%. The majority of the CVCs (97.9%) were inserted via the subclavian or the internal jugular routes and there was no statistical difference in CR-BSI between them (p = 0.83). Number of attempts more than one had a higher rate of CR-BSI compared to single attempt with percentage of 7.0% vs 4.8% (p = 0.22). The top two organisms were Klebseilla pneumoniae and Pseudomonas aeruginosa. In conclusion, the incidence of CR-BSI in our ICU was 9.43 CR-BSI per 1000 catheter days. The risk factors were duration of CVC in situ, venue of insertion and use of 4 lumen catheter for total parenteral nutrition. The site of insertion, number of lumen up to 3 lumens and the number of attempts were not risk factors.

Anaesthetizing patients with Long QT Syndrome is a major challenge, as the potential for sudden catastrophic cardiovascular collapse is well known. We present a 15-year-old boy with Long QT Syndrome who presented for an elective renal transplant. All electrolyte concentration abnormalities were corrected preoperative and adequate beta-blockade was maintained. The patient was given a target controlled infusion of propofol, together with opioids and atracurium. Anaesthesia was uneventful and the patient was extubated at the end of the surgical procedure.

The objective of this survey was to obtain a self-reported assessment of the use of information technology (IT) by final year medical students. Two hundred and sixty five students responded to a questionnaire survey. 81.5% of students considered their computer skills adequate, while 87.9% had access to computers outside the campus. Most students reported adequate skills at word processing, e-mailing and surfing the Internet. Fifty three percent of students spent three hours or more each week on the computer. While students indicated a general willingness to access Internet-based materials, further steps need to be taken to increase the use of this method of instruction.

Results of construct validity and reliability of the SF-36 are described, based on data from a multi-centre study on asthmatics and a population based survey. Questionnaire refinement was carried out between the two studies. Quality of data was good, with all items having less than 0.5% missing values. Floor and/or ceiling effects were observed for REE, REP, PF and SF. For scaling assumptions, correlations between each items and its hypothesized scale were all above 0.50, except for one item in PF. and for both items in SF. Item discriminant validity was an issue for items in VT, SF and MH scales. Cronbach's as for all scales exceeded the recommended 0.70 level, except for SF. Only one latent dimension was identified in principal component analysis, and only 52-53% of variance accounted for. As expected, PF shows high correlations with the physical component while MH was highly correlated with the mental component. Contrasting findings in the loadings of other scales were observed in the asthma data. Age, disease severity and presence of self-reported handicap/disability significantly affect PF, while MH demonstrates no obvious pattern with declining age. In essence, the Malay version of SF-36 could be used in Malaysia, with its generally acceptable internal consistency and validity. The caveat is in the call for additional domains of importance to Malaysians that is not covered by the instrument, and in the caution to be employed when using and construing the instrument.

This was a prospective survey using a standard questionnaire to determine the prevalence of use of oral traditional medicine and food supplements among patients with rheumatic diseases. Among the 141 patients surveyed, we found that 69% of the patients were consuming food supplements, 35% were using traditional medicine and 45% had used traditional medicine at some time or other. Females were more likely to use food supplements (P < 0017); especially among those with higher education (p < 0.036). There was no statistical difference between those who had ever consumed compared to those who never used traditional medicines. The Chinese were more likely than others to be using traditional medicine (p < 0.007). Vitamin C and B were the most commonly used food supplements. More than two thirds of the patients obtained their traditional medicine from non-medical personnel. More than half of them used 2 or more types of traditional medicine for more than two months. Spending on traditional medicine was noted to be modest with 73% spending less than one hundred ringgit a month for their traditional treatment. Doctors need to be aware of the possible interactions between these 'self-medications' and the conventionally prescribed medication.

Over a seven-year period, 170 cases of humerus fractures were plated in Hospital Melaka. Of these, 131 cases were successfully traced for this study. Besides looking at fracture epidemiology, its relationship with radial nerve injury was examined. The incidence of post-traumatic wrist drop in closed and compound fractures were 14.9% and 35.3% respectively. In relation to the site of fracture, lower third fracture had the highest incidence of wrist drop (29%). The recovery from post-traumatic wrist drop was 83%. The average duration taken for recovery was 11.8 weeks. The incidence of post-operative wrist drop was high at 17.6% but all recovered during follow-up.

Introduction: The flow-volume curves of patients with obstructive sleep apnoea (OSA) obtained during the awake state are frequently abnormal., Objective: To determine 1) the relationship between the awake respiratory function and the severity of sleep-disordered breathing in a group of Malaysian patients with the OSA syndrome and 2) the frequency of flow-volume curve abnormality in these patients., Materials and Methods: A retrospective analysis of the data from respiratory function tests during wakefulness and nocturnal polysomnography was performed on 48 patients with OSA. The severity of OSA was defined by the apnoea-hypopnoea index (AHI) and the lowest oxygen saturation during sleep (SpO2nadir)., Results: AHI had a significant relationship with alveolar-arterial oxygen gradient (r = 0.34, p = 0.046) and SpO2nadir (r = -0.49, p < 0.001) but not with any anthropometric parameter or the other awake respiratory function variables measured. SpO2nadir had a significant relationship with body mass index (r = -0.54, p < 0.001), neck circumference (r = -0.39, p = 0.013), awake room air PaO2 (r = 0.61, p < 0.001), alveolar-arterial oxygen gradient (r = -0.41, p = 0.015) and baseline supine SpO2 (r = 0.53, p < 0.001). There was no correlation between SpO2nadir and any spirometric or static lung volume parameters. The maximum inspiratory and maximum expiratory flow-volume curves of 26 patients (54%) showed a ratio of forced expiratory flow to forced inspiratory flow at mid-vital capacity (FEF50/FIF50) greater than one. In addition, flow oscillations (the "sawtooth" sign) were noted in the inspiratory and/or expiratory flow-volume curves of 21 patients (44%), 9 of whom did not have an FEF50/FIF50 > 1. Altogether, the maximum flow-volume curves during wakefulness of 35 (73%) of the 48 patients showed variable upper airway obstruction and/or flow oscillations. However, the presence of these two upper airway abnormalities, either occurring alone or together did not have an effect on the severity of OSA as measured by the AHI or SpO2nadir., Conclusions: Abnormalities of the flow-volume loop consistent with inspiratory flow limitation and/or upper airway instability during wakefulness are common in patients with the OSA syndrome. The degree of oxygen desaturation during sleep in these patients is related to their awake oxygenation status.

Phenothiazines have been associated with various ocular adverse effects, in particular cataract and corneal deposits. Several effects are vision threatening. Awareness of these effects, in particular by Psychiatrists and Ophthalmologist, is essential for prompt diagnosis and appropriate treatment. We report two patients presented to us with corneal deposits and lenticular opacities following long term use of Phenothiazines.

Forty patients were treated with ofloxacin for community acquired lower respiratory tract infections. Eighteen pathogens were isolated in sputum; Streptococcus pneumoniae (4) and Haemophilus influenzae (4) were the most common, followed by Klebsiella pneumoniae (3), Klebsiella spp. (2), Staphylococcus anreus (2), Pseudomonas spp. (2), and Pseudomonas aeruginosa (1). Ofloxacin 200 mg every 12 hours was administered for an average of 3.7 days intravenously followed by 5.4 days orally. Response to therapy was judged to be cure in 38 (95%; 95% C.I., 85%-95%) patients, failure in one (2.5%) and "indeterminate" in one (2.5%).

An asymptomatic subject with radiographic changes due to welders' siderosis is described. This condition has not been well recognized and described in our community. Siderosis of the lung is generally considered to be a benign condition not associated with respiratory symptoms. However, recent reports have associated welding with various disorders of pulmonary function as well as lung cancer. There is a need for future epidemiological studies to better define the risk of long term welding.

Tuberculosis and malignancy are two common causes of exudative pleural effusions. In this retrospective study of 52 patients with tuberculous pleural effusions and 32 patients with malignant effusions, the median age of patients with malignant effusions (68.5 years) was older than that of patients with tuberculous effusions (34.5 years) (p < 0.001). Both types of effusion occurred more frequently on the right side and there was no difference between them in terms of right-sided dominance. A higher percentage of patients with malignant pleural effusions (44%) presented with large effusions than patients with tuberculous effusions (12%) (x2 = 11.33, p = 0.001). A higher proportion of patients with tuberculous effusion had lymphocyte predominant effusions and tuberculous effusions had higher lymphocyte percentage, lower red cell count, and higher protein content. However, there was considerable overlap of these characteristics of both types of effusions.
