Balakrishnan B, Rus RM, Chan KH, Martin AG, Awang MS

Asian J Neurosurg, 2019 4 3;14(1):201-205.
PMID: 30937035 DOI: 10.4103/ajns.AJNS_49_18

Context: Postconcussion syndrome (PCS) is a set of symptoms occurred after a mild traumatic brain injury (MTBI). Aims: This study aims to determine the prevalence of PCS in a young adult population from a single Neurological Centre in Malaysia's East Coast and to evaluate the factors associated with PCS in MTBI patients.
Settings and Design: This was a cross-sectional study conducted in a Neurological Centre at Hospital Tengku Ampuan Afzan, Kuantan, Pahang, Malaysia, from January 2016 to December 2016.
Subjects and Methods: A total of 209 patients; 133 males and 76 females, in the age range of 16-84 years, were randomly recruited for this study. All the selected patients were subjected to the checklist for diagnosis of PCS as per International Statistical Classification of Diseases and Related Health Problems 10th edition classification at a 2-week interval.
Statistical Analysis Used: Descriptive statistic and Multivariable Logistic Regression Model were used for frequency and percentage analyses of categorical variables, using SPSS version 23.0.
Results: Only 20 patients were identified with PCS. There were more female (70%) patients with PCS than the male (30%) patients. The prevalence of PCS for 2 weeks, 3 and 6 months since injuries were 9.6%, 8.1%, and 8.1% respectively. Majority (80%) of the patients were found to have PCS due to road traffic accidents, while the remaining were attributed to assault (15%), and falls (5%). Among the sample population, 25% were smokers, while 10% of them had either skull fracture or premorbidity.
Conclusion: Less than 10% of patients with MTBI had PCS after 6 months' following trauma. None of the variables tested were significant factors for the development of PCS symptoms.

Large-scale food-borne outbreaks caused by Salmonella are rarely seen nowadays, thanks to the advanced nature of the medical system. However, small, localised outbreaks in certain regions still exist and could possess a huge threat to the public health if eradication measure is not initiated. This review discusses the progress of Salmonella detection approaches covering their basic principles, characteristics, applications, and performances. Conventional Salmonella detection is usually performed using a culture-based method, which is time-consuming, labour intensive, and unsuitable for on-site testing and high-throughput analysis. To date, there are many detection methods with a unique detection system available for Salmonella detection utilising immunological-based techniques, molecular-based techniques, mass spectrometry, spectroscopy, optical phenotyping, and biosensor methods. The electrochemical biosensor has growing interest in Salmonella detection mainly due to its excellent sensitivity, rapidity, and portability. The use of a highly specific bioreceptor, such as aptamers, and the application of nanomaterials are contributing factors to these excellent characteristics. Furthermore, insight on the types of biorecognition elements, the principles of electrochemical transduction elements, and the miniaturisation potential of electrochemical biosensors are discussed.

PMID: 17599028

Nerve conduction study is essential in the diagnosis of focal neuropathies and diffuse polyneuropathies. There are many factors that can affect nerve conduction velocity, and age is one of them. Most of the many studies of this effect, and the values from them, were on Caucasian subjects. Therefore, this study was designed to investigate the effect of age on conduction velocity among healthy Asian Malay subjects by analyzing its influence on the median, ulnar, and sural nerves.
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.

The history of neurosurgery in Malaysia traces back to 1962 and is filled with stories of vibrant and humble neurosurgeons who have dedicated their life to patients and professions. The early development of neurological and neurosurgical services begins from the establishment of the neurosurgery unit at Hospital Kuala Lumpur (HKL), followed by the foundation of the Tunku Abdul Rahman Neuroscience Institute (IKTAR). Due to the exponentially increased demand for the care of neurosurgical patients, many universities and government hospitals have opened their neurosurgical units. In 2001, the formal residency training programme (USM Masters in Neurosurgery) started and since then has produced qualified neurosurgeons that empowered and shaped the present generation. The formation of the Neurosurgical Association of Malaysia (NAM) is another turning point towards bidirectional collaboration with the World Federation of Neurosurgical Societies (WFNS). Many opportunities were created for educational activities and the expansion of subspecialties in neurosurgery. This article describes the impact of the past neurosurgeons and the endeavors that they had gone through; the present neurosurgeons who pioneered the current neurosurgical services in Malaysia, and the future neurosurgeons that will continue the legacy and bring neurosurgery further ahead in this country.

Abdul Rahman N', Nurumal MS, Awang MS, Mohd Shah ANS

Australas Emerg Care, 2020 Dec;23(4):240-246.
PMID: 32713770 DOI: 10.1016/j.auec.2020.06.005

INTRODUCTION: Emergency departments (EDs) routinely provide discharge instructions due to a large number of patients with mild traumatic brain injury (mTBI) being discharged home directly from ED. This study aims to evaluate the quality of available mTBI discharge instructions provided by EDs of Malaysia government hospitals.
METHODS: All 132 EDs were requested for a copy of written discharge instruction given to the patients. The mTBI discharge instructions were evaluated using the Patient Education Materials Assessment-Printable Tool (PEMAT-P) for understandability and actionability. Readability was measured using an online readability tool of Malay text. The content was compared against the discharge instructions recommended by established guidelines.
RESULTS: 49 articles were eligible for the study. 26 of the articles met the criteria of understandability, and 3 met the criteria for actionability. The average readability level met the ability of average adult. Most of the discharge instructions focused on emergency symptoms, and none contained post-concussion features.
CONCLUSION: Majority of the discharge instructions provided were appropriate for average people to read but difficult to understand and act upon. Important information was neglected in most discharge instructions. Thus, revision and future development of mTBI discharge instruction should consider health literacy demand and cognitive ability to process such information.

Chronic pain is a common medical issue. Beside chronic devastating pain, patients also suffer dysfunction more generally, including in the physical, emotional, social, recreational, vocational, financial, and legal spheres. Integrated multidisciplinary and multimodal chronic pain management programmes offer clear evidence for relief of suffering and return to functional lifestyles.
Fulltext Scalene myofascial pain syndrome mimicking cervical disc prolapse: a report of two cases

Abd Jalil N, Awang MS, Omar M

Scalene myofascial pain syndrome is a regional pain syndrome wherein pain originates over the neck area and radiates down to the arm. This condition may present as primary or secondary to underlying cervical pathology. Although scalene myofascial pain syndrome is a well known medical entity, it is often misdiagnosed as being some other neck pain associated with radiculopathy, such as cervical disc prolapse, cervical spinal stenosis and thoracic outlet syndrome. Because scalene myofascial pain syndrome mimics cervical radiculopathy, this condition often leads to mismanagement, which can, in turn, result in persistent pain and suffering. In the worst-case scenarios, patients may be subjected to unjustifiable surgical intervention. Because the clinical findings in scalene myofascial pain syndrome are "pathognomonic", clinicians should be aware of ways to recognize this disorder and be able to differentiate it from other conditions that present with neck pain and rediculopathy. We present two cases of unilateral scalene myofascial pain syndrome that significantly impaired the patients' functioning and quality of life. This case report serves to create awareness about the existence of the syndrome and to highlight the potential morbidity due to clinical misdiagnosis.
