    Lim, W.K., Ling, H.T., R. Ramanathan
    Journal of Occupational Safety and Health, 2011;8(2):19-24.
    MyJurnal
    Brush cutting is a commonly performed activity occupationally as well as recreationally in Malaysia. There are various occupational injuries reported related to brush cutting, for example foreign body penetration. There were 11 reported cases of foreign body penetrated in leg of brush cutting workers admitted to orthopaedic ward in Hospital Raja Permaisuri Bainun from the period of January till October 2009. Among the cases, 4 were surgically removed under local anaesthesia and 7 cases performed under general anesthesia. 2 cases reported foreign body penetrated into tibia bone. There were many contributing factors to the injury, which include lack of protective measures for workers, engineering property of brush cutting machine and education on handling of equipment. It is vital to study the factors separately in order to determine and recommend useful preventive measures. However, the actual numbers of cases are under reported and awareness of the problem is undermined.

  2. Fulltext Development of decellularized meniscus using closed sonication treatment system: potential scaffolds for orthopedics tissue engineering applications
    Yusof F, Sha'ban M, Azhim A
    Int J Nanomedicine, 2019;14:5491-5502.
    PMID: 31410000 DOI: 10.2147/IJN.S207270
    PURPOSE: Meniscus is a fibrocartilagenous tissue that cannot effectively heal due to its complex structure and presence of avascular zone. Thus, tissue engineering and regenerative medicine offer an alternative for the regeneration of meniscus tissues using bioscaffolds as a replacement for the damaged one. The aim of this study was to prepare an ideal meniscus bioscaffold with minimal adverse effect on extracellular matrix components (ECMs) using a sonication treatment system.

    METHODS: The decellularization was achieved using a developed closed sonication treatment system for 10 hrs, and continued with a washing process for 5 days. For the control, a simple immersion treatment was set as a benchmark to compare the decellularization efficiency. Histological and biochemical assays were conducted to investigate the cell removal and retention of the vital extracellular matrix. Surface ultrastructure of the prepared scaffolds was evaluated using scanning electron microscope at 5,000× magnification viewed from cross and longitudinal sections. In addition, the biomechanical properties were investigated through ball indentation testing to study the stiffness, residual forces and compression characteristics. Statistical significance between the samples was determined with p-value =0.05.

    RESULTS: Histological and biochemical assays confirmed the elimination of antigenic cellular components with the retention of the vital extracellular matrix within the sonicated scaffolds. However, there was a significant removal of sulfated glycosaminoglycans. The surface histoarchitecture portrayed the preserved collagen fibril orientation and arrangement. However, there were minor disruptions on the structure, with few empty micropores formed which represented cell lacunae. The biomechanical properties of bioscaffolds showed the retention of viscoelastic behavior of the scaffolds which mimic native tissues. After immersion treatment, those scaffolds had poor results compared to the sonicated scaffolds due to the inefficiency of the treatment.

    CONCLUSION: In conclusion, this study reported that the closed sonication treatment system had high capabilities to prepare ideal bioscaffolds with excellent removal of cellular components, and retained extracellular matrix and biomechanical properties.

  4. Fulltext Operative internal fixation of isolated femoral diaphyseal fractures - is interlocking nail the best option?
    Zairul-Nizam, Z.F.
    International Medical Journal Malaysia, 2008;7(2):25-30.
    MyJurnal
    Femoral fractures are one of the commonest fractures encountered in orthopaedic practice. Over the years, treatment of this injury has evolved tremendously. The initial non-operative methods of reduction and stabilization have largely been replaced by operative fixation. There are currently three basic modes of internal fixation of femoral diaphyseal fractures in the adult age group: plate and screws, intramedullary Kuntscher nailing, and interlocking nailing. The objective of this study is to determine whether the so-called more ‘technologically advanced’ interlocking nailing results in better outcome compared to the more ‘traditional’ plate and screws, and Kuntscher nailing. It is found that, in terms of time to union and final function after an average of just under 2 years post-operative period, the group of patients who had interlocking nailing fared poorer. A review of relevant literature will then be presented.

    MyJurnal
    The Kulliyyah of Medicine of IIUM has pioneered the Islamization of Medicine in Malaysia since its establishment in year 1994. Therefore, it is timely to review publications on Islamization by the kulliyyah and also to propose a classification system in the field of researches to promote an organized, comprehensive, inclusive and relevant Islamization process. The aim is to review and classify publications on Islamization performed by the members of Kulliyyah of Medicine, International Islamic University Malaysia (IIUM). All researches and publications deposited in the IIUM Repository (IREP) under the Kulliyyah of Medicine between 1st of January 2000 and 31st of August 2016 were reviewed. Journal articles, posters and proceedings with Islamization themes were identified. These publications were classified based on common themes to either of the following; 1) "Islamic Principles and Related Rulings in Medicine"; 2) "Medical Treatment for Muslim Patients"; 3) "Islamic Input in Medical Practices"; 4) "Ruqyah and Tibb an-Nabawi in Contemporary Medicine". A total of 1616 items (journal articles, abstracts and proceedings) were reviewed. Sixty-one (3.8%) of them were related to Islamization. The major contributors to writings in Islamization are the Orthopaedics, Traumatology and Rehabilitation Department (10%) followed by the Internal Medicine Department (7.9%), from their total deposits in the IREP database. Majority (36.5%) of work were done in "Islamic Principles and Related Rulings in Medicine", which dwells in subjects such as euthanasia, autonomy and doctor-patient relationship followed by "Islamic Input in Medical Practice" (28.6%) which was related to topics in the medical curriculum such as Fiqh Ibadah for the sick. Twenty-three point eight percent (23.8%) of work were in the "Medical Treatment for Muslim Patients" which focuses on Ramadan and diabetes and joint problems and Solat. Minimal work (7.9%) was done in the "Ruqyah and Tibb an-Nabawi in Contemporary Medicine" category. Low number of publications on Islamization was deposited in the IREP database for the past 15 years. Based on the proposed classification system, majority of publications were on "Islamic Principles and Related Rulings in Medicine" and "Islamic Input in Medical Practice". More work is required on the theme of "Medical Treatment for Muslim Patients" and "Ruqyah and Tibb an-Nabawi in Contemporary Medicine".

    MyJurnal
    Objective: This study aims to determine the incidence rate of phlebitis among patients with peripheral intravenous catheter. Methods: An observational study was conducted in one of the hospitals in East Coast Malaysia. There were 321 data collected among patients who had peripheral intravenous catheter in medical, gynecology and orthopedic wards. The incidence of phlebitis was evaluated using modified Visual Infusion Phlebitis score checklist. Results: The incidence of phlebitis, was found out to be 36.1% (n=116/321). Most patients who developed phlebitis had visual infusion phlebitis, with a score of two (34.9%) and the rest developed phlebitis with a score of three (1.2%). Conclusion: This high incidence of phlebitis indicated a worrying outcome. Therefore, the study findings suggested that a specific guideline on post insertion management of peripheral intravenous catheter should be revised which may help in reducing more incidence of phlebitis, subsequently reduce infection in ward, and provide more safety environment in hospital and reducing cost in managing infection control.

    PMID: 22106619
    The relationship between orthopaedic surgeons and the device industry is one that is mutually beneficial and productive. However there are skeletons in the closet. The financial implications of this relationship have come under intense scrutiny. The sponsorships and the financial benefits of this symbiotic relationship have been found to cross the boundaries considered acceptable to ethical practice of the profession. In India, the ethical transgressions resulting from unhealthy associations between the orthopaedic surgeon and the industry have yet to be given due importance. Adequate rules and regulations are yet to be enforced and self-regulation is practically non-existent. It is essential to deal with the problem and potential implications that can arise from this kind of misconduct at the organisational level and enforce them for compliance.

  12. Fulltext Parametric evaluation of electrical discharge coatings on nickel-titanium shape memory alloy in deionized water
    Mansor AF, Azmi AI, Zain MZM, Jamaluddin R
    Heliyon, 2020 Aug;6(8):e04812.
    PMID: 32913911 DOI: 10.1016/j.heliyon.2020.e04812
    Nickel-titanium shape memory alloy (NiTi) has a unique capacity to restore its initial shape after deformation, which is highly applicable to orthopaedic implantations, especially for the minimization of invasive surgeries. The high nickel content of this alloy can lead to unfavourable effects on the human body upon dissolution; thus, a reliable barrier of coatings on the NiTi surface is required to alleviate the nickel migration and increase its biocompatibility. In this paper, analyses of a titanium oxide layer development on NiTi surface using electrical discharge coating (EDC) process is presented. The recast layer thickness, crater sizes, and surface roughness were characterized based on five parameters; polarity, discharge duration, pulse interval, peak current, and gap voltage. The results show that the discharge duration is the most significant parameter to influence all responses, followed by peak current. The surface characteristics of the EDC substrate is depending on the crater formations and is highly correlated with the discharge energy intensity. As a result, appropriate parametric conditions of the electrical discharge coating process can enhance the NiTi surface for future medical applications, without compromising the shape memory effect.

    Education in Medicine Journal, 2013;5(4):42-50.
    MyJurnal
    Context: Community-based medical education (CBME) has become widely accepted as an important innovation in undergraduate medical education. In curriculum featuring CBME, students are acquainted with the community early in their studies however; the impact of this training can be judged best to see them practice the required aspects of CBME. Malaysia is a multiracial country with a very strong community dependant life style. Main national health problems have called for a change in health profession education from traditional hospital based health care to community-based delivery system. Three major university's medical schools that either practice community oriented or community based medical education in undergraduate medical curriculum are evaluated. Universiti Sains Malaysia (USM) has a community based medical education (CBME) curriculum as Community and Family Case Study (CFCS) compared to a community oriented education curriculum (COE) adopted by Universiti Malaya (UM) and Universiti Kebangsaan Malaysia (UKM). However, UM at the time of undertaking this study back in 2005 was though practicing COE has also later opted CBME as CFCS.

    Objective: To determine whether medical graduates from USM with a community-based medical education in its curriculum for more than 25 years are inspired to have stronger commitment towards community health as shown in their on-job practice of medicine compared to other graduates from UM and UKM, who have adopted community-oriented medical education program.

    Method: A questionnaire-based pilot study with 12 items (variables) was designed to obtain supervisor's opinion on commitment of interns towards the health of community they serve. The questionnaire was administered to a randomized group of 85 specialists supervising the internship training program in five major disciplines including internal medicine, surgery, orthopaedic, gynaecology and obstetrics and paediatric medicine. The data received from 62 respondents from five major disciplines was analyzed utilizing SPSS version 12.0.1.

    Result: The responses received from 62 supervisors on an inventory in which 9 out of 12 variables were directly related to community commitments of interns. It was shown that the USM graduates who were taught through a CBME curriculum have performed better than the graduates from UM and UKM who followed a COE curriculum. P-value (< 0.001) was highly significant and consistent with higher mean score in those variables.

    Conclusion: The graduates taught through a CBME curriculum performed better in community commitments towards patients care compared to graduates from COE curriculum.

    Newly prepared titanium alloy (Ti-13Zr-13Nb (TZN)) using powder metallurgy is considered in this investigation. Titanium alloys (TZN) are used in hip and knee replacement for orthopedic implants. Conventional machining, TZN alloys produce higher tool wear rate and poor surface quality, but this can be reduced by Electrical Discharge Machining (EDM) method. Moreover, EDM produce good biological and corrosion resistant surface. In this research, experiments were conducted by considering the influential process factors such as pulse on time, pulse off time, voltage, and current. The experiments were designed based on Response Surface Methodology (RSM) of face centered central composite design. Analysis of Variance (ANOVA) was conducted to identify the significance process factors and their relation to output responses such as Electrode Wear Rate (EWR), Surface Roughness (SR) and Material Removal Rate (MRR). Further, an empirical model was developed by RSM in order to predict the output responses.

    This systematic review was aimed to evaluate the effectiveness of technology-enhanced learning (TEL) used in medical teaching for undergraduate medical students. The objectives are to (a) identify various teaching modalities which are used to enhance TEL; (b) evaluate whether TEL is more effective than traditional learning (TL) in cognitive and affective learning domain outcome. The empirical studies were searched in the following databases: Google Scholar, MEDLINE, ERIC, ProQuest, Cochrane Library and Scopus. All papers published from 2008 to 2018 were included. From eligible studies, the study design, study field, study population, intervention methods, type of assessment and learning achievement were abstracted and summarized the information. The search results were independently reviewed by two authors. From a pool of 1384 articles, 43 eligible articles were identified, enrolling 7292 undergraduate medical students examining comparative study between TEL and traditional learning. The results showed that there was a high degree of heterogeneity seen amongst the included studies in terms of TEL modalities used. The majority of intervention studies favoured online resources, while the rest used various offline multimedia electronic devices, virtual simulations and blended modes. Overall findings showed promising data that TEL is better than TL with regards to knowledge gain and skill acquisition, as well as providing higher student satisfaction. In all, the findings present blended learning in a positive and promising light in time, particularly where systematic reviews on technology-enhanced learning in the field of the undergraduate medical programme have produced mixed result.REVIEW ARTICLEA Systematic Literature Review on Technology-Enhanced Learning in Medical EducationMay Honey Ohn1*, Bareth Ravindran2, Chan Zhi Wei3, Khin Maung Ohn4, Ng Pey Luen5Borneo Journal of Medical Sciences 14 (1) January, 2020: 3 – 171 Emergency Department, Sandwell & West Birmingham NHS Trust, United Kingdom2 Surgical Department, Hospital Tuanku Ja’afar Seremban, Kuala Lumpur, Malaysia3 Orthopaedics Department, Hospital Sungai Buloh, Kuala Lumpur, Malaysia4 Department of Surgery, Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia5 Radiology Department, Hospital Queen Elizabeth II, Sabah, Malaysia* Corresponding author’s email: mayhoney.ohn@gmail.com Received: 14 July 2019 Accepted: 5 November 2019Borneo Journal of Medical SciencesBJMSKeywords: blended learning, technology-enhanced learning, medical education, hybrid learning, undergraduate medical students
