  1. Fulltext Robotic neurosurgery: a preliminary study using an active vision-guided robotic arm for bone drilling and endoscopic manoeuvres
    Awang MS, Abdullah MZ
    Malays J Med Sci, 2011 Apr;18(2):53-7.
    PMID: 22135587 MyJurnal
    Surgical robots have been appearing in operating rooms over the past decade, and neurosurgery has been one of the pioneers in this area. In neurosurgery, the clinical use of robots has been limited to stereotactic procedures and endoscopic manoeuvres, although the brain is a unique organ and well-suited for robotic application. The aim of this study was to assess the ability of our vision-guided robotic system to perform basic neurosurgical procedures.

  2. Fulltext A randomised control trial on the use of topical methicillin in reducing post-operative ventriculoperitoneal shunt infection
    Theophilus SC, Adnan JS
    Malays J Med Sci, 2011 Jan;18(1):30-7.
    PMID: 22135571
    BACKGROUND: A double-blind randomised control study was conducted on all patients who were admitted or referred to the Department of Neurosurgery, Sultanah Aminah Hospital, Johor Bahru, with a diagnosis of hydrocephalus where a ventriculoperitoneal shunt was indicated.
    METHODS: The period of study was from November 2005 to May 2007, and the follow-up period was 3 months after surgery. Randomisation was carried out in the operating room prior to the procedure. The scrub nurse selected a sealed envelope, which contained the assignment of each patient to 1 of 2 treatment groups: Group 1 patients were treated with topical methicillin, and Group 2 patients were not treated with topical methicillin. Prophylactic antibiotic, cefuroxime (25 mg/kg) was given intravenously at induction. Standard sterile operative technique was followed in preparing and draping the patients.
    RESULTS: A total of 90 patients were recruited in the study, and 13 (14.4%) patients developed an infection within 3 months post-operation. Group 1 had a 8.9% risk of infection, and Group 2 had a 20% risk; however, there was no statistically significant post-operative ventriculoperitoneal shunt (VPS) infection reduction with the use of topical methicillin in VPS surgery (P = 0.230). Multivariate analysis showed that only duration of surgery had a significant influence on the incidence of post-operative VPS infection in the non-methicillin group (P = 0.02). The non-methicillin group had an 8 times greater risk of developing post-operative VPS infection than the methicillin group if surgery lasted longer than 1 hour.
    CONCLUSION: Topical methicillin had no significance in the reduction of post-operative VPS infection.

    The development of neurosurgical services and training in Malaysia began in 1963, with the first centre established in its capital city at Hospital Kuala Lumpur, aimed to provide much needed neurosurgical services and training in the field of neurology and neurosurgery. This center subsequently expanded in 1975 with the establishment of the Tunku Abdul Rahman Neuroscience Institute (IKTAR); which integrated the three allied interdependent disciplines of neurosurgery, neurology and psychiatry. The establishment of this institute catalysed the rapid expansion of neurosurgical services in Malaysia and paved the way for development of comprehensive training for doctors, nurses, and paramedics. This culminated in the establishments of a local comprehensive neurosurgery training program for doctors in 2001; followed by a training program for nurses and paramedics in 2006. To date, there are more than 60 neurosurgeons providing expert care in 11 centers across Malaysia, along with trained personnel in the field of neurosciences.

  4. Fulltext The implementation of teleneurosurgery in the management of referrals to a neurosurgical department in hospital sultanah amninah johor bahru
    Hassan R, Siregar JA, A Rahman Mohd NA
    Malays J Med Sci, 2014 Mar;21(2):54-62.
    PMID: 24876808 MyJurnal
    Telemedicine in neurosurgery or teleneurosurgery has been widely used for transmission of clinical data and images throughout the country since its implementation in 2006. The impact is a reduction of patient number that need to be reviewed in the level III hospitals and an increment in the number of patients that are kept in level II hospitals for observation by the primary team. This translates to reduction of unnecessary transfer of patients and subsequently cost benefits for patients and medical providers. The main aim is to determine the amount of reduction in unnecessary transfer by the implementation of teleneurosurgery in the management of referrals to neurosurgical department in Hospital Sultanah Amninah Johor Bahru (HSAJB). Other factors associated with transfer decision are also evaluated.

  5. Fulltext The First Awake Clipping of a Brain Aneurysm in Malaysia and in ASEAN: Achieving International Standards
    Idris Z, Kandasamy R, Neoh YY, Abdullah JM, Wan Hassan WMN, Mat Hassan ME
    Malays J Med Sci, 2018 Feb;25(1):1-4.
    PMID: 29599629 DOI: 10.21315/mjms2018.25.1.1
    World-renowned neurosurgeon, Professor Saleem Abdulrauf, has been featured in several medical journals for his successful "Awake Brain Aneurysm Surgery". Regarded as a "world first", this surgery, involves clipping un-ruptured brain aneurysms while patients are awake. Only one or two neurosurgery centres worldwide are capable of this. Performing the surgery while the patient is awake lowers risks of brain ischemia with neurological deficits and ventilator associated morbidities. The technique has been viewed as the start of a new era in brain surgery. Physicians from the Universiti Sains Malaysia (USM) School of Medical Sciences, at the Health Campus in Kelantan, headed by Professor Dr Zamzuri Idris (neurosurgeon) and Dr Wan Mohd Nazaruddin Wan Hassan (neuroanaesthetist), recently performed a similar procedure, the first such surgery in Malaysia and Southeast Asia. The USM team can therefore be considered to be among the first few to have done this brain surgery and achieved successful patient outcomes.

  6. Utility of multimaterial 3D printers in creating models with pathological entities to enhance the training experience of neurosurgeons
    Waran V, Narayanan V, Karuppiah R, Owen SL, Aziz T
    J. Neurosurg., 2014 Feb;120(2):489-92.
    PMID: 24321044 DOI: 10.3171/2013.11.JNS131066
    The advent of multimaterial 3D printers allows the creation of neurosurgical models of a more realistic nature, mimicking real tissues. The authors used the latest generation of 3D printer to create a model, with an inbuilt pathological entity, of varying consistency and density. Using this model the authors were able to take trainees through the basic steps, from navigation and planning of skin flap to performing initial steps in a craniotomy and simple tumor excision. As the technology advances, models of this nature may be able to supplement the training of neurosurgeons in a simulated operating theater environment, thus improving the training experience.

  7. Telemedicine in neurosurgery using international digital telephone services between Japan and Malaysia--technical note
    Houkin K, Fukuhara S, Selladurai BM, Zurin AA, Ishak M, Kuroda S, et al.
    Neurol. Med. Chir. (Tokyo), 1999 Oct;39(11):773-7; discussion 777-8.
    PMID: 10598447
    A new image transmission and teleconference system using international digital telephone services was established between Japan and Malaysia. This new system consists of an ordinary personal computer, image scanner, and terminal adapter for digital telephone lines. The quality of images transferred using this system was high enough for diagnosis and discussion except for images such as radiographs requiring huge data transfer. Transmission of one image took approximately 20 seconds. The cost performance was almost equal to the conventional mailing system. The most remarkable advantage of this new system is the high quality of transferred images, the cost and time performance, and security of the medical information. New communication systems using international digital networks including the internet may allow re-distribution of medical resources between advanced countries and developing countries in neurosurgery.

  8. Frequency and Causes of Line of Sight Issues During Neurosurgical Procedures Using Optical Image-Guided Systems
    Mehbodniya AH, Moghavvemi M, Narayanan V, Waran V
    World Neurosurg, 2019 Feb;122:e449-e454.
    PMID: 30347306 DOI: 10.1016/j.wneu.2018.10.069
    BACKGROUND: Navigation (image guidance) is an essential tool in modern neurosurgery, and most surgeons use an optical tracking system. Although the technology is accurate and reliable, one often is confronted by line of sight issues that interrupt the flow of an operation. There has been feedback on the matter, but the actual problem has not been accurately quantified, therefore making this the primary aim of this study. It is particularly important given that robotic technology is gradually making its way into neurosurgery and most of these devices depend on optical navigation when procedures are being conducted.

    METHODS: In this study, the frequency and causes of line of sight issues is assessed using recordings of Navigation probe locations and its synchronised video recordings.

    RESULTS: The mentioned experiment conducted for a series of 15 neurosurgical operations. This issue occured in all these surgeries except one. Maximum duration of issue presisting reached up to 56% of the navigation usage time.

    CONCLUSIONS: The arrangment of staff and equipment is a key factor in avoiding this issue.

  9. Injecting realism in surgical training-initial simulation experience with custom 3D models
    Waran V, Narayanan V, Karuppiah R, Pancharatnam D, Chandran H, Raman R, et al.
    J Surg Educ, 2014 Mar-Apr;71(2):193-7.
    PMID: 24602709 DOI: 10.1016/j.jsurg.2013.08.010
    The traditionally accepted form of training is direct supervision by an expert; however, modern trends in medicine have made this progressively more difficult to achieve. A 3-dimensional printer makes it possible to convert patients imaging data into accurate models, thus allowing the possibility to reproduce models with pathology. This enables a large number of trainees to be trained simultaneously using realistic models simulating actual neurosurgical procedures. The aim of this study was to assess the usefulness of these models in training surgeons to perform standard procedures that require complex techniques and equipment.

  11. Fulltext Equitable Access to State-of-the-Art Medical Technology-a Malaysian Mini-Public-Private Partnership Case Study
    Waran V, Thillainathan R, Karuppiah R, Pickard JD
    World Neurosurg, 2022 01;157:135-142.
    PMID: 34687934 DOI: 10.1016/j.wneu.2021.10.112
    BACKGROUND: The provision of equitable and affordable health care has become increasingly challenging as advanced technology is introduced, particularly in developing countries. We explored the hypothesis that focused, small-scale mini-public-private partnerships have a potential role in providing equitable and affordable access to advanced technology for the benefit of all patients in developing nations, particularly middle-income countries.

    METHODS: A clinician-led financial plan was developed at the University of Malaya to create the Centre for Image Guidance and Minimally Invasive Therapy (CIGMIT) to provide an integrated platform for high-end care for Malaysian patients of all ages, both public and private, requiring complex neurosurgical and spinal procedures and stereotactic and intensity-modulated radiotherapy. The challenges faced during development of the plan were documented together with an audit of patient throughput and analyses of financial risk and return.

    RESULTS: CIGMIT opened in 2015. Patient throughput, both public and private, progressively increased in all facilities. In 2015-2019, 37,724 patients used the Centre's facilities. CIGMIT has become progressively more profitable for the University of Malaya, the public and private hospitals, and the investor. CIGMIT has weathered the challenges posed by coronavirus disease 19.

    CONCLUSIONS: Focused, small-scale mini-public-private partnerships have a potential role in providing advanced technology for the benefit of patients in developing nations, particularly middle-income countries, subject to an approach that balances equity of access between public and private health care systems with fair reward.

    Primary orbital lymphoma is a rare entity with only 1% of extranodal lymphomas. They usually present to ophthalmologist and surgical reserved for biopsy or tissue diagnosis. We present a patient who was referred to neurosurgery for a rapid growing orbital lymphoma. It grows from a small nodule in the eyelid to a huge, aggressive, disfiguring lesion invading bone and dura with intracranial extension within 3 months. The patient was treated with total surgical excision followed by systemic chemotherapy.

  15. Tailoring teleconsultation to meet the current needs of neurosurgical services: a multimodality oriented neurosurgical consultation
    Narenthiranathan NR, Adnan JS, Haspani MS
    Stud Health Technol Inform, 2010;161:112-21.
    PMID: 21191164
    Teleconsultation in Neurosurgery was introduced in Malaysia in 2006 with the aims of enhancing quality services in the field of Neurosurgery. The present teleconsultation system is equipped with user friendly features which allow physicians to send and neurosurgeons to gain access to patient data in a swift and effective manner. In the past, teleconsultation in neurosurgery was tied with teleradiology, however we have now developed a multimodality system to cater specifically for neurosurgery. In Malaysia, the teleconsultation service is gaining momentum as evidenced by the large volume of cases channeled through this system. 944 cases within a span of 4 months were recorded on the system. 54.5% of the cases were trauma, 33.2% stroke, 6.1% intracranial tumours, 2% of cases were of spinal pathology, 2% pediatric anomalies and 2.2% intracranial infections. 50.2% of the referrals were after regular working hours reflecting the need for dedicated teleneurosurgery consultative services and the ability to review referrals outside of hospitals. Only 36% of cases needed emergency transfers and 9.9% of the cases were managed remotely at distant hospitals. Another 9.4% of the cases were either transferred electively or brought to the clinic for consultation. The above findings emphasise the importance of teleconsultation as a means to provide wide medical coverage within the region.

  18. NeuroVerse: neurosurgery in the era of Metaverse and other technological breakthroughs
    Kundu M, Ng JC, Awuah WA, Huang H, Yarlagadda R, Mehta A, et al.
    Postgrad Med J, 2023 May 22;99(1170):240-243.
    PMID: 36892407 DOI: 10.1093/postmj/qgad002
    The tremendous evolution in modern technology has led to a paradigm shift in neurosurgery. The latest advancements such as augmented reality, virtual reality, and mobile applications have been incorporated into neurosurgical practice. NeuroVerse, representing the application of the metaverse in neurosurgery, brings enormous potential to neurology and neurosurgery. Implementation of NeuroVerse could potentially elevate neurosurgical and interventional procedures, enhance medical visits and patient care, and reshape neurosurgical training. However, it is also vital to consider the challenges that may be associated with its implementation, such as privacy issues, cybersecurity breaches, ethical concerns, and widening of existing healthcare inequalities. NeuroVerse adds phenomenal dimensions to the neurosurgical environment for patients, doctors, and trainees, and represents an incomparable advancement in the delivery of medicine. Therefore, more research is needed to encourage widespread use of the metaverse in healthcare, particularly focusing on the areas of morality and credibility. Although the metaverse is expected to expand rapidly during and after the COVID-19 pandemic, it remains to be seen whether it represents an emerging technology that will revolutionize our society and healthcare or simply an immature condition of the future.

  19. The molecular landscape of neurological disorders: insights from single-cell RNA sequencing in neurology and neurosurgery
    Awuah WA, Ahluwalia A, Ghosh S, Roy S, Tan JK, Adebusoye FT, et al.
    Eur J Med Res, 2023 Nov 16;28(1):529.
    PMID: 37974227 DOI: 10.1186/s40001-023-01504-w
    Single-cell ribonucleic acid sequencing (scRNA-seq) has emerged as a transformative technology in neurological and neurosurgical research, revolutionising our comprehension of complex neurological disorders. In brain tumours, scRNA-seq has provided valuable insights into cancer heterogeneity, the tumour microenvironment, treatment resistance, and invasion patterns. It has also elucidated the brain tri-lineage cancer hierarchy and addressed limitations of current models. Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis have been molecularly subtyped, dysregulated pathways have been identified, and potential therapeutic targets have been revealed using scRNA-seq. In epilepsy, scRNA-seq has explored the cellular and molecular heterogeneity underlying the condition, uncovering unique glial subpopulations and dysregulation of the immune system. ScRNA-seq has characterised distinct cellular constituents and responses to spinal cord injury in spinal cord diseases, as well as provided molecular signatures of various cell types and identified interactions involved in vascular remodelling. Furthermore, scRNA-seq has shed light on the molecular complexities of cerebrovascular diseases, such as stroke, providing insights into specific genes, cell-specific expression patterns, and potential therapeutic interventions. This review highlights the potential of scRNA-seq in guiding precision medicine approaches, identifying clinical biomarkers, and facilitating therapeutic discovery. However, challenges related to data analysis, standardisation, sample acquisition, scalability, and cost-effectiveness need to be addressed. Despite these challenges, scRNA-seq has the potential to transform clinical practice in neurological and neurosurgical research by providing personalised insights and improving patient outcomes.

    Lichterman BL, Wong SN, Likhterman LB
    World Neurosurg, 2019 Aug;128:149-157.
    PMID: 31042604 DOI: 10.1016/j.wneu.2019.04.178
    The article is dedicated to the life and work of Dr. Roy Selby (1930-2002), an American neurosurgeon who founded neurosurgery in Malaysia. Dr. Selby stayed in Malaysia from July 1963 to May 1970. He opened the first neurosurgical department at the general hospital in Kuala Lumpur and established a training program under which Malaysian physicians and nurses were sent to neurosurgery centers in the United States and Canada. Some physicians came back and headed local neurosurgical units. On his return to the United States, Dr. Selby practiced neurosurgery until 1986, when he had to give it up due to the impact of progressive congestive heart failure. From 1986 to 1994, Dr. Selby taught graduate courses in the Department of Psychology at East Texas State University, Texarkana, Texas. He was a pioneer of spinal surgery and founded the Lumbar Spine Society. Dr. Selby was a world citizen neurosurgeon and advocated international standards of training in neurosurgery. From 1985 to 1994, he was chairman of the Archives Committee of the American Association of Neurological Surgeons. Dr. Selby serves as a model of a physician as a humanist.
