Fulltext Traumatic herniation of the heart into the right hemithorax

Wong PS

Med J Malaysia, 1999 Dec;54(4):523-5.
PMID: 11072475

Pericardial rupture after blunt chest trauma is described in the literature. This case report summarises our experience with a 22-year old male patient who suffered blunt chest trauma during a motor vehicle accident. On admission no serious injuries could be detected, but 3 hours later, displacement of the heart to the right hemithorax combined with sudden cardiac failure appeared. Emergency thoracotomy revealed a right-sided rupture of the pericardium with complete herniation of the heart into the right pleural cavity and consequent strangulation by the margins of the pericardial defect.

Fulltext Workplace fatalities in Brunei Darussalam

Win KN, Trivedi A, Lai AS

Ind Health, 2018 Nov 21;56(6):566-571.
PMID: 29973468 DOI: 10.2486/indhealth.2018-0053

In 2012, there were about 2.3 million deaths worldwide attributed to work. The highest workplace fatality rate (WFR) was reported on construction sites due to high risk activities. Globally, fall from height is the leading cause of fatal injuries for construction workers. The objectives are to determine Brunei Darussalam's demographic distribution of occupational fatality; identify causal agents and industry where occupational fatalities commonly occur; and determine WFR by year. This cross-sectional study retrospectively reviewed records of occupational fatality which were notified to the Occupational Health Division, Ministry of Health, from January 2012 until December 2016. Notified occupational fatalities in Brunei over a five-year period was 50. Most of the cases were in 31-40 age group. 38% of fatality cases occurred in Indonesian workers. 60% were from the Construction industry. 38% were due to fall from height. WFR averaged 5.28 and the highest industry-specific fatality rate was seen in the Construction industry, ranging from 27.94 to 56.45 per 100,000 workers. WFR for Brunei Darussalam from 2012 to 2016 was similar to that of Malaysia, but higher than Singapore and the UK. Industry-specific fatality rate for the Construction and Manufacturing industries were higher than those of Singapore and the UK.

Fulltext Successful ankle replantation in two cases with different presentations

Wen APY, Jusoh MH, Saad AZM, Halim AS, Faisham NWIW, Azman WSW

Arch Plast Surg, 2020 Mar;47(2):182-186.
PMID: 31462030 DOI: 10.5999/aps.2018.00514

We report our experience of treating two patients with ankle amputation with different presentations. The first case was a clean-cut sharp amputation. The second case was an avulsion injury following a motor vehicle accident in a patient who arrived 8 hours after the injury. Replantation was successful in both cases. In avulsion injuries, a secondary operation for wound coverage is required at a later stage. With good strategy and a support team, encouraging limb survival outcomes are possible post-replantation.

Evaluation of factors causing lateral migration of light non-aqueous phase liquids (LNAPLs) in onshore oil spill accidents

Waqar A

Environ Sci Pollut Res Int, 2024 Feb;31(7):10853-10873.
PMID: 38214856 DOI: 10.1007/s11356-024-31844-x

Contamination of groundwater by harmful substances poses significant risks to both drinking water sources and aquatic ecosystems, making it a critical environmental concern. Most on-land spill events release organic molecules known as light non-aqueous phase liquids (LNAPLs), which then seep into the ground. Due to their low density and organic composition, they tend to float as they reach the water table. LNAPLs encompass a wide range of non-aqueous phase liquids, including various petroleum products, and can, over time, develop carcinogenic chemicals in water. However, due to frequent changes in hydraulic head, the confinement may fail to contain them, causing them to extend outward. When it contaminates water wells, people cannot reliably consume the water. The removal of dangerous contaminants from groundwater aquifers is made more challenging by LNAPLs. It is imperative to analyze the mechanisms governing LNAPL migration. As a response to this need and the associated dispersion of contaminants into adjacent aquifers, we have conducted a comprehensive qualitative literature review encompassing the years 2000-2022. Groundwater variability, soil structure, and precipitation have been identified as the three primary influential factors, ranked in the following order of significance. The rate of migration is shown to rise dramatically in response to changes in groundwater levels. Different saturation zones and confinement have a major effect on the lateral migration velocity. When the various saturation zones reach a balance, LNAPLs will stop moving. Although higher confinement slows the rate of lateral migration, it speeds up vertical migration. Beyond this, the lateral or vertical movement is also influenced by differences in the permeability of soil strata. Reduced mobility and tighter containment are the outcomes of migrating through fine-grained, low-porosity sand. The gaseous and liquid phases of LNAPLs move more quickly through coarse-grained soils. Due to the complexities and uncertainties associated with LNAPL behavior, accurately foreseeing the future spread of LNAPLs can be challenging. Although studies have utilized modeling techniques to simulate and predict LNAPL migration, the inherent complexities and uncertainties in the subsurface environment make it difficult to precisely predict the extent of LNAPL spread in the future. The granular soil structure considerably affects the porosity and pore pressure.

Wan Ali WAA, Soh EZF, Abdullah S, Narin Singh PSG, Ahmad AA, Sapuan J

Cureus, 2021 Jan 13;13(1):e12691.
PMID: 33604222 DOI: 10.7759/cureus.12691

Introduction Closed reduction is an effective method of treatment for distal end radius fractures. We present a case series of patients with distal end radius fractures who underwent closed manipulative reduction using the periosteal block. We describe the technique in detail and examine its efficacy in pain lowering effect during closed reduction. Methods Nineteen patients with distal end radial and ulnar fractures were included and grouped based on the Frykman classification. The reduction was performed using a periosteal block of 10 ml of 2% lignocaine injection. The severity of pain was recorded by utilizing the visual analog scale (VAS) in five phases: 1) before injection, 2) after 15 minutes of analgesia in a resting position, 3) during minimal motion, 4) during full manipulation and reduction, and 5) post-procedure. The VAS scoring was classified as painless (VAS score of 0), mild pain (VAS score between 1-3), and painful (VAS score of 4 and above). Results The study included 19 patients [median age of 53 years (range: 18-88 years)]; there were 11 (58%) males and eight (42%) females. The mechanism of injury was a fall (n=12, 63%) or a motor vehicle accident (n=7, 37%). There was a statistically significant reduction of pain between phase one and all the other phases. Between the different fracture configurations, there was no significant difference in pain reduction. The most painful phase was expected to be phase four, ie, during full manipulation, in which four (21%) patients had a VAS score of 0, 12 (63%) patients had a VAS score between 1-3, and three (16%) patients had a VAS score of 4. Thus, 16 out of 19 patients (84%) had no or minimal pain during the most painful phase. There were no complications from the periosteal blocks. Conclusions The periosteal nerve block is an effective procedure providing satisfactory analgesia during the reduction of distal radial and ulnar fractures. It has no side effects and is free from complications associated with conventional sedation.

Fulltext Concomitant Traumatic Peroneal Tendon Dislocation and Medial Malleolus Fracture: A Case Report

Vosoughi AR, Erfani MA

Malays Orthop J, 2018 Mar;12(1):57-59.
PMID: 29725517 DOI: 10.5704/MOJ.1803.014

Peroneal tendon dislocation in association with medial malleolus fracture is a very rare traumatic injury to the ankle. A 19-year old male patient was referred after injury sustained in a motorcycle accident with car, with concomitant traumatic peroneal tendon dislocation and medial malleolus fracture. The possible mechanism of this unusual injury could have been sudden external rotation force to the pronated foot in full dorsiflexed position of the ankle. Diagnosis of peroneal tendon subluxation or dislocation should be carefully evaluated in patients with single medial malleolus fracture.

Increased work pace is unprofitable: a beef-cutting case study

Vogel K, Karltun J, Yeow PH, Eklund J

Meat Sci, 2015 Jul;105:81-8.
PMID: 25828161 DOI: 10.1016/j.meatsci.2015.03.009

The beef industry worldwide is showing a trend towards increased cutting pace aimed at higher profits. However, prior research in the duck meat industry suggested that a higher cutting pace reduced quality and yield, leading to losses. This study aimed to test this hypothesis by investigating the effects of varying beef-cutting paces on yield, quality and economy. A field experiment was conducted on six workers cutting beef fillet, sirloin and entrecôte. Three types of paces were sequentially tested: Baseline (i.e., status quo), 'Quantity focus' (i.e., pace required to maximise quantity) and 'Quality focus' (i.e., pace required to minimise errors). The results showed a significant drop in yield, increased rate of quality deficiency and economic losses with the change to 'Quantity focus' (from Baseline and 'Quality focus') for all meat types. Workers supported these results and also added health problems to the list. The results confirmed that an increased cutting pace is unprofitable.

Fulltext Initial leucocytosis and other significant indicators of poor outcome in severe traumatic brain injury: an observational study

Vijian K, Teo EG, Kanesen D, Wong ASH

Chinese neurosurgical journal, 2020;6:5.
PMID: 32922934 DOI: 10.1186/s41016-020-0185-4

Background: Globally, severe traumatic brain injury (TBI) has been the principal cause of mortality among individuals aged 45 and below. The incidence of road traffic accidents in Malaysia is one of the highest in the world with thousands of victims sustaining severe disabilities. The aim of this study is to determine the association between leucocytosis and extended Glasgow Outcome Scale (GOSE) scores as well the relationship of other factors and the outcomes of severe TBI.
Methods: This was a retrospective observational study. A total of 44 consecutive patients who were admitted to Sarawak General Hospital from January 1, 2018, to September 30, 2018, with severe TBI were included. Data were collected from discharge summaries and hospital medical records. Chi-square and t test were used. SPSS was employed.
Results: Of a total of 44 patients with severe TBI, 18 patients (41%) died during the same admission. The mean age of patients was 37.1 years with 93.2% of affected patients being male. 56.9% of patients presented with a Glasgow Coma Scale (GCS) of 6 and less. A large percentage (86.3%) were discharged with a GOSE of less than 7. Older age and low admission GCS (6 and less) were significantly associated with poor GOSE scores on discharge and after 6 months (p < 0.05) on multivariate analysis. Leucocytosis on admission was also associated with poor outcomes where patients with higher total white counts on presentation attaining lower GOSE scores (p < 0.05).
Conclusion: We concluded that leucocytosis was significantly associated with poor outcomes in severe TBI patients in addition to other factors such as advanced age and poor GCS on arrival.

Tung SE, Ng XH, Chin YS, Mohd Taib MN

Child Care Health Dev, 2016 Jul;42(4):478-85.
PMID: 27272607 DOI: 10.1111/cch.12355

BACKGROUND: This study aimed to evaluate parental perception of neighbourhood environments and safety in association with children's physical activity among primary school children in Klang, Selangor, Malaysia.
METHODS: A total of 250 children (9-12 years of age) and their parents participated in this cross-sectional study. Physical Activity Questionnaire for Older Children and Neighbourhood Environmental Walkability Scale as well as questions on constrained behaviours (avoidance and defensive behaviours) were used to assess the children's physical activity and parental perception of neighbourhood environment and safety, respectively.
RESULTS: More than one-third (36.0%) of the children were physically inactive compared with only a small percentage (4.8%) who were physically active, with boys achieving higher physical activity levels than girls (t = 2.564, P = 0.011). For the environmental scale, parents' perception of land-use mix (access) (r = 0.173, P = 0.006), traffic hazards (r = -0.152, P = 0.016) and defensive behaviour (r = -0.024, P = 0.143) correlated significantly with children's physical activity. In multiple linear regression analysis, child's gender (β = -0.226; P = 0.003), parent's education (β = 0.140; P = 0.001), household income (β = 0.151; P = 0.024), land-use mix (access) (β = 0.134; P = 0.011) and defensive behaviour (β = -0.017; P = 0.038) were significantly associated with physical activity in children (R = 0.349, F = 6.760; P

Engaging policy makers in road safety research in Malaysia: a theoretical and contextual analysis

Tran NT, Hyder AA, Kulanthayan S, Singh S, Umar RS

Health Policy, 2009 Apr;90(1):58-65.
PMID: 18937995 DOI: 10.1016/j.healthpol.2008.08.009

Road traffic injuries (RTIs) are a growing public health problem that must be addressed through evidence-based interventions including policy-level changes such as the enactment of legislation to mandate specific behaviors and practices. Policy makers need to be engaged in road safety research to ensure that road safety policies are grounded in scientific evidence. This paper examines the strategies used to engage policy makers and other stakeholder groups and discusses the challenges that result from a multi-disciplinary, inter-sectoral collaboration. A framework for engaging policy makers in research was developed and applied to describe an example of collective road safety research in Malaysia. Key components of this framework include readiness, assessment, planning, implementation/evaluation, and policy development/sustainability. The case study of a collaborative intervention trial for the prevention of motorcycle crashes and deaths in Malaysia serves as a model for policy engagement by road safety and injury researchers. The analytic description of this research process in Malaysia demonstrates that the framework, through its five stages, can be used as a tool to guide the integration of needed research evidence into policy for road safety and injury prevention.

Fulltext Review of ocular injuries in Malaysia

Thevi T, Reddy SC

Malaysian Journal of Public Health Medicine, 2017;17(1):69-77.
MyJurnal

Ocular injuries or trauma to the eye can be caused by variety of objects resulting in a spectrum of lesions in the eye. We did a Pubmed/Google/Science Direct search to review the spectrum of ocular injuries in Malaysia. In our review, we included 28 papers providing information on ocular injuries which were published from Malaysia during the period 1991-2016 in different medical journals. Prevalence was more among males with an average age of 35 years. Among adults they were more common in the workplace but in children it occurred at home. Few wore protective glasses at work. The mode of injury was due to sharp objects hitting the eye, motor vehicle and domestic accidents, firecrackers, chemicals and rarer causes like superglue and durian fruit. Prognostic factors for outcome were the initial visual acuity, length of the wound, associated factors like hyphaema, intraocular foreign body and vitreous prolapse. Missing the diagnosis of perforation of the eyeball is possible without eliciting a proper history. Protective devices must be worn to prevent injuries. Display of health education charts showing the effect of injuries in the eye and their preventive measures in health centres, private hospitals, schools, factories and sports centres will increase the awareness of public about the ocular injuries. It is important to diagnose the tissues involved in ocular trauma by the general practitioners and primary care physicians and refer the patients to the Ophthalmologist urgently for treatment to salvage vision. Compensation mechanisms should then be put forth in terms of rehabilitation and for monetary loss.

Clinical clues for head injuries amongst Malaysian infants: accidental or non-accidental?

Thalayasingam M, Veerakumarasivam A, Kulanthayan S, Khairuddin F, Cheah IG

Injury, 2012 Dec;43(12):2083-7.
PMID: 22424957 DOI: 10.1016/j.injury.2012.02.010

Identifying the differences between infants with non-accidental head injuries (NAHI) and accidental head injuries (AHI) may help alert clinicians to recognize markers of abuse. A retrospective review of infants <1 year of age admitted to a tertiary referral centre in Malaysia over a two year period with a diagnosis of head injury or abnormal computed tomography head scans was conducted to identify the clinical features pointing towards a diagnosis of NAHI by comparing the socio-demographics, presenting complaints, clinical features and the extent of hospital investigations carried out. NAHI infants were more likely to be symptomatic, under a non-related caregiver's supervision, and presented with inconsistent or no known mechanism of injury. Subdural haemorrhages were more common in NAHI infants. The history, mechanism of injury, presenting signs and symptoms as well as the nature of the injuries sustained are all valuable clues as to whether a head injury sustained during infancy is likely to be accidental or not.

Microsimulation modelling of driver behaviour towards alternative warning devices at railway level crossings

Tey LS, Zhu S, Ferreira L, Wallis G

Accid Anal Prev, 2014 Oct;71:177-82.
PMID: 24929822 DOI: 10.1016/j.aap.2014.05.014

Level crossings are amongst the most complex of road safety issues, due to the addition of rail infrastructure, trains and train operations. The differences in the operational characteristics of different warning devices together with varying crossing, traffic or/and train characteristics, cause different driver behaviour at crossings. This paper compares driver behaviour towards two novel warning devices (rumble strips and in-vehicle audio warning) with two conventional warning devices (flashing light and stop sign) at railway level crossings using microsimulation modelling. Two safety performance indicators directly related to collision risks, violation and time-to-collision, were adopted. Results indicated the active systems were more effective at reducing likely collisions compared to passive devices. With the combined application of driving simulation and traffic microsimulation modelling, traffic safety performance indicators for a level crossing can be estimated. From these, relative safety comparisons for the different traffic devices are derived, or even for absolute safety evaluation with proper calibration from field investigations.

Measuring driver responses at railway level crossings

Tey LS, Ferreira L, Wallace A

Accid Anal Prev, 2011 Nov;43(6):2134-2141.
PMID: 21819844 DOI: 10.1016/j.aap.2011.06.003

Railway level crossings are amongst the most complex of road safety control systems, due to the conflicts between road vehicles and rail infrastructure, trains and train operations. Driver behaviour at railway crossings is the major collision factor. The main objective of the present paper was to evaluate the existing conventional warning devices in relation to driver behaviour. The common conventional warning devices in Australia are a stop sign (passive), flashing lights and a half boom-barrier with flashing lights (active). The data were collected using two approaches, namely: field video recordings at selected sites and a driving simulator in a laboratory. This paper describes and compares the driver response results from both the field survey and the driving simulator. The conclusion drawn is that different types of warning systems resulted in varying driver responses at crossings. The results showed that on average driver responses to passive crossings were poor when compared to active ones. The field results were consistent with the simulator results for the existing conventional warning devices and hence they may be used to calibrate the simulator for further evaluation of alternative warning systems.

Fulltext A review of intraocular foreign bodies treated at the University Hospital Kuala Lumpur

Teoh GH, Yow CS

Med J Malaysia, 1982 Mar;37(1):7-10.
PMID: 7121351

A retrospective study of intraocular foreign bodies treated at the University Hospital over 10 years from 1970 - 1979 was carried out. Of the 48 cases reviewed, nine were anterior chamber foreign bodies while the rest were posterior segment foreign bodies. The anterior chamber foreign bodies had better visual prognosis as compared to the posterior segment foreign bodies. Most of the patients were young Chinese males and most of the injuries were due to accidents at work involving the 'hand hammer' (includes other implements used as a hammer).

Fulltext Osh audit compliance at National Service Training Programme (NSTP) camps in Malaysia: training elements

Tengku Hizir Tengku Abdul Rashid, Mohd Esa Baruji, Shahronizam Noordin, Mohd Kashfullah Razali

Journal of Occupational Safety and Health, 2015;12(1):101-104.
MyJurnal

There were a number of accidents reported throughout the implementation of the National Services Training
Programme (NSTP) since 2004 until 2012. The National Services Training Department (NSTD) is responsible for
the Occupational Safety and Health (OSH) aspects in the NSTP camps. The study was conducted with its objective
to compare the levels of OSH audit compliance at NSTP between 2011 and 2012. A cross sectional method was
used, involving a total of 67 randomly selected NSTP camps. The data analysis was conducted on two types of
audit checklists using SPSS version 2.1. The r-value of 0.197 obtained indicates a weak relationship between the
document review and physical training element. The p-value of 0.118, meanwhile, shows that there is no statistically
significant correlation between the results of document review and physical training element. Most of the elements
show an increased percentage of compliance as a result of initiatives taken by the Camp Training Management and
the Camp Operator. Despite an improved compliance level seen from 2011 to 2012, NSTD should look into certain
critical elements considered high risk by the regulatory requirements. NSTD should also continue with its initiatives
to enhance safety and health aspects in NSTP camps not only for the benefit of the trainees but also for themselves.

PMID: 25417946

This article describes the methodology of this bibliography. A search was conducted on the following: (1) bibliographic databases (PubMed, Scopus, and other databases) using search terms that maximize the retrieval of Malaysian publications; (2) Individual journal search of Malaysian healthrelated journals; (3) A targeted search of Google and Google Scholar; (4) Searching of Malaysian institutional repositories; (5) Searching of Ministry of Health and Clinical Research Centre website. The publication years were limited to 2000- 2013. The citations were imported or manually entered into bibliographic software Refworks. After removing duplicates, and correcting data entry errors, PubMed's Medical Subject Headings (MeSH terms) were added. Clinical research is coded using the definition "patient-oriented-research or research conducted with human subjects (or on material of human origin) for which the investigator directly interacts with the human subjects at some point during the study." A bibliography of citations [n=2056] that fit the criteria of clinical research in Malaysia in selected topics within five domains was generated: Cancers [589], Cardiovascular diseases [432], Infections [795], Injuries [142], and Mental Health [582]. This is done by retrieving citations with the appropriate MESH terms, as follow: For cancers (Breast Neoplasms; Colorectal Neoplasms; Uterine Cervical Neoplasms), for cardiovascular diseases (Coronary Disease; Hypertension; Stroke), for infections (Dengue; Enterovirus Infections, HIV Infections; Malaria; Nipah Virus; Tuberculosis), for injuries (Accidents, Occupational; Accidents, Traffic; Child Abuse; Occupational Injuries), for mental health (Depression; Depressive Disorder; Depressive Disorder, Major; Drug Users; Psychotic Disorders; Suicide; Suicide, Attempted; Suicidal Ideation; Substance- Related Disorders).
