Malaysian Public Interest in Common Medical Problems: A 10-Year Google Trends Analysis.

Background An analysis of internet search has been performed to evaluate the public interest in health problems. Google Trends (GT) serves as a free platform to analyse the search traffic for specific terms in the Google search engine. This observational study aims to investigate the trend of Malaysian population in using the Google search engine on common medical problems and explore the geographical influence on the language used. Material and method Fifteen pairs of keywords, in Malay and English language, were chosen after going through forward and backward translation and vetting by a panel of experts. GT data for the selected keywords from 1st of January 2011 to 31st of December 2020 was extracted. Trend analysis was performed using paired t-test between the first half of the decade and the second half of the decade. The different languages used were analysed based on geographical variation using paired t-test. Results The public interest on those keywords was markedly increased in the second half of the decade with 29 out of 30 keywords showing statistically significant difference. Majority of the states preferred to use Malay keywords, especially those residing at the East Coast of Peninsular Malaysia. Conclusion This observational study illustrates the ability of GT to track healthcare interest among Malaysian population. GT provides a good platform to analyse specific healthcare interest in Malaysian population, but investigators have to bear in mind the geographical influence on the language used.

The needs of traumatic brain injury survivors' caregivers and the implication required during the COVID-19 pandemic: Public health issues.

BACKGROUND: Traumatic brain injury (TBI) survivors require attention and dependence from their primary caregiver. This is because TBI is a defect that affects both the psychological and physical functions of the victim. Caregivers play an essential role in providing the adequate care victims need to adjust to the new problems they may experience due to their condition, as family members alone may not be able to provide for their needs. In particular, TBI caregivers may face specific challenges when assisting their patients in handling unexpected changes to their daily routines. Therefore, this quantitative study aims to explore the needs of caregivers, their coping mechanisms towards stressful and traumatic circumstances, and how they provide care to their loved ones during the COVID-19 pandemic. DESIGN AND METHODS: It was conducted with ten caregivers of individuals suffering from traumatic brain injury, that were selected using a theoretical sampling method. Data were obtained using a semi-structured interview guide, which helped the caregivers provide their responses. Meanwhile, data analysis was performed using the NVIVO analysis software. RESULTS: The results showed that there were, three significant themes namely, (a) Support needed, (b) the information need for care, and (c) developing self-resilience. The results also showed that caregivers really need support from the various parties, and the participants lack information on specific care techniques for the severe traumatic brain injury (TBI) survivors. CONCLUSION: In conclusion, caregivers require approval and seek more useful information to provide excellent care to their loved ones. Being aware of the caregiver's needs would enable them to offer improved customized care.

History of Neurosurgery in Malaysia: The Past, Present and Future.

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.

A Rare Presentation of Spinal Schwannoma Causing Conus Medullaris Syndrome: A Case Series on Surgical Outcome.

INTRODUCTION: Spinal schwannoma can occur anywhere along the spinal cord but is predominantly seen in the cervical and thoracic region.It composes mainly of well-differentiated schwann cell and is benign in nature. It is typically seen in the peripheral nerves and is commonly associated with neurofibromatosis. Up to 80% of cases, spinal schwannoma is reported to be intradural in location and 15% of cases have both intradural and extradural components. Spinal schwannoma rarely causes conus medullaris syndrome. CASE REPORT: In this case series, all three female patients in their 4th and 5th decades of life presented with conus medullaris syndrome. Lower back pain, radiculopathy, lower limb weakness, and urinary incontinence are their main clinical presentation. Magnetic resonance imaging shows a well-defined intradural, extramedullary mass compressing onto the conus medullary region. These patients undergone microscopic assisted excision of the tumor and had remarkably good early outcome despite the advanced presentation of neurological deficit. CONCLUSION: Despite the late presentation with significant neurological deficit, surgical excision of spinal schwannomas carries a good prognosis postoperatively due to their benign nature and extramedullary location.

Emergency department discharge instruction for mild traumatic brain injury: Evaluation on readability, understandability, actionability and content.

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.

Prevalence of Postconcussion Syndrome after Mild Traumatic Brain Injury in Young Adults from a Single Neurosurgical Center in East Coast of Malaysia.

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.

Epilepsy Surgery in Hospital Universiti Sains Malaysia: Our Experiences since 2004.

Epilepsy surgery has been performed by a few centres in Malaysia, including Hospital Universiti Sains Malaysia (HUSM). To date, a total of 15 patients have undergone epilepsy surgery in HUSM. The epilepsy surgery included anterior temporal lobectomy (ATL) with amygdalohippocampectomy (AH) and Vagal nerve stimulation (VNS). The surgical outcomes of the patients were assessed using the International League Against Epilepsy (ILAE) outcome scale. The ILAE scores for patients who underwent ATL with AH were comparatively better than those who underwent VNS. One of the patient who underwent ATL with AH and frontal lesionectomy was found to have psychosis during follow up. Epilepsy surgery has proven to be an important treatment for medically resistant epilepsy. Thus it is important to raise public awareness regarding epilepsy and its treatment.

A Rare Case of Monostotic Spinal Fibrous Dysplasia Mimicking Solitary Metastatic Lesion of Thyroid Carcinoma.

Monostotic fibrous dysplasia of the vertebra is a rare entity. A case of a 53-year-old lady who presented with an 8 months history of pain in the thoracic spine region with paraparesis is discussed. She had a history of papillary thyroid carcinoma and had undergone total thyroidectomy one year prior to her current problem. Magnetic resonance imaging revealed isolated osteolytic lesion over the posterior element of the T12 vertebra with narrowing of the spinal canal causing compression of the cord. The diagnosis of fibrous dysplasia was made histologically. Fibrous dysplasia rarely occurs in axial bones compared with peripheral bones. This case illustrates that osteolytic lesion of the vertebrae should be evaluated with detailed radiological and histopathological examination before an empirical diagnosis of spinal metastasis is made in an adult with a background history of primary malignancy well-known to spread to the bone.

Cystic Meningioma Masquerading as a Metastatic Tumor: A Case Report.

Cystic meningioma is a rare form of intracranial meningioma. Meningiomas are typically solid tumors but may rarely have cystic components. The diagnosis of cystic meningioma is clinically challenging as the finding of multiple intra-axial tumors, including metastatic tumors, is relatively common. We report a case of cystic meningioma initially diagnosed as a metastatic tumor from a recurrence of acute lymphoid leukemia. However, postoperative histopathological examination demonstrated an atypical meningioma.

BACKGROUND: The study assesses the capability and accuracy of a robotic arm to perform burr holes. MATERIAL AND METHODS: The robotic systems are instructed to recognize targets on artificial skull models placed in different positions and to make burr holes. RESULTS: The accuracy ranged from 0.1 to 1.0 mm. CONCLUSION: Robotic arms are capable to perform basic surgical tasks. However, further improvement needs to be done to refine its accuracy and capability.

Robotic neurosurgery: a preliminary study using an active vision-guided robotic arm for bone drilling and endoscopic manoeuvres.

BACKGROUND: 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. METHODS: THE STUDY WAS DIVIDED INTO TWO PARTS: bone drilling and endoscopic manoeuvres. The robotic system was instructed to recognise targets on artificial skull models placed in different positions (supine, lateral, sitting, and prone) and to make burr holes. A total of 10 selected burr holes were used to assess the capability of the robot to insert an endoscope. RESULTS: The accuracy ranged 0.1-1.0 mm with repeatability ranged 0.03-0.92 mm. CONCLUSION: Generally, the present robotic system is able to perform the surgical tasks. However, further study is needed to refine the robotic system, including the safety mechanisms.

The role of a high augmentation index in spontaneous intracerebral hemorrhage to prognosticate mortality.

The aim of the study was to determine the prognostic value of a high augmentation index, which was a surrogate marker of arterial stiffness in patients with spontaneous intracerebral hemorrhage. The outcome was divided into two groups in which the following data were collected in a computer running SphygmoCor CvMS software version 8.2. Logistic regression analysis was carried out among significant variables to identify an independent predictor of 6-month outcome and mortality. Sixty patients were recruited into the study. Admission Glasgow Coma Scale score (OR, 0.7; 95% CI, 0.450-0.971; P=0.035), total white cell count (OR, 1.2; 95% CI, 1.028-1.453; P=0.023) and hematoma volume (OR, 1.1; 95% CI, 1.024-1.204; P=0.011) were found to be statistically significant for identifying poor 6-month outcome in multivariate analysis. Factors independently associated with mortality were a high augmentation index (OR, 8.6; 95% CI, 1.794-40.940; P=0.007) and midline shift (OR, 7.5; 95% CI, 1.809-31.004; P=0.005). Admission Glasgow Coma Scale score, total white cell count and hematoma volume were significant predictors for poor 6-month outcome, and a high augmentation index and midline shift were predictors for 6-month mortality in this study.

Role of high augmentation index in spontaneous intracerebral haemorrhage.

BACKGROUND: Intracerebral haemorrhage (ICH) is the most disabling and least treatable form of stroke. Its risk factors include old age, hypertension, diabetes mellitus, hypercholesterolaemia, smoking and high alcohol intake, which are also associated with arterial stiffness. The aim of the present study was to determine the prognostic value of high augmentation index (AI), which is a surrogate marker of arterial stiffness, in patients with spontaneous ICH. METHODS: A prospective study of 60 patients with spontaneous supratentorial ICH was conducted. Outcome was assessed using the Modified Rankin Scale at 3 months follow-up. Data were collected on age and sex, risk factors for ICH, clinical parameters, laboratory parameters, radiological findings and hospital management. Logistic regression analysis was carried out to identify independent predictors of 3-month outcome and mortality. RESULTS: Admission Glasgow Coma Scale score (OR, 0.7; 95% CI, 0.450-0.971; p = 0.035), total leukocyte count (OR,1.2; 95% CI, 1.028-1.453; p = 0.023) and haematoma volume (OR, 1.1; 95% CI, 1.024-1.204; p = 0.011) were found to be statistically significant in multivariate analysis of 3-month poor outcome. Factors independently associated with mortality were high AI (OR, 8.6; 95%CI, 1.748-40.940; p = 0.007) and midline shift (OR, 7.5; 95%CI, 1.809-31.004; p = 0.005). CONCLUSION: Admission Glasgow Coma Scale score, total leukocyte count and haematoma volume were significant predictors for 3-month poor outcome; high AI and midline shift were significant predictors for 3-month mortality.

Retrospective review of outcomes of a multimodal chronic pain service in a major teaching hospital: a preliminary experience in universiti sains malaysia.

BACKGROUND: 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. MATERIALS AND METHODS: This retrospective review was performed in order to evaluate one-year outcomes among all newly referred patients of the multimodal chronic pain service at Hospital Universiti Sains Malaysia (HUSM). All patients received multimodal pain therapy, including pharmacological, physical, and psychological therapy, exercise, and pain intervention. The variables evaluated were based on a patient's global pain assessments, which were made using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), modified by patient self-report, and were taken within days to months of commencing our multimodal pain regime. RESULTS: A total of 169 patients were enrolled in this study. Out of this number, 102 (60.4%) were seen at the pain clinic, and 67 (39.6%) were referred while they were inpatients. About one-third of the patients had chronic pain due to cancer. Our data showed that 128 (75.7%) of our chronic pain patients were successfully managed when ≥50% of pain relief (as measured by their VAS score) was achieved at any point during the course of the study period. In addition, 104 patients (61.5%) showed improvement in their modified ODI by 50% or more. CONCLUSION: A multimodal chronic pain service plays a significant role in managing chronic pain patients in a major hospital, as it is capable of delivering comprehensive and attainable care to manage refractory and intractable chronic pain.

Nerve conduction study of healthy Asian Malays: the influence of age on median, ulnar, and sural nerves.

BACKGROUND: 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. MATERIAL/METHODS: A total of 250 healthy subjects were recruited. The subjects were divided into four age groups. The nerves tested were the median, ulnar, and sural nerves. Surface electrodes were used and the temperature was kept constant. The nerves were stimulated and recorded at specific sites both for motor and sensory conduction velocities. RESULTS: The mean velocities for the median and ulnar nerves, both motor and sensory, were 54.71+/-5.69 m/s (motor) and 54.04+/-7.02 m/s for the median nerve and 60.57+/-5.00 m/s (motor) and 52.92+/-5.89 m/s for the ulnar nerve. The mean velocity for the sural nerve was 47.97+/-4.48 m/s. Only median motor conduction velocity showed a significant reduction with increasing age (p=0.000). CONCLUSIONS: This study did not show any significant effect of age on nerve conduction velocities except for median motor conduction velocity. For future research it is planned to extend the recruitment to subjects who are much older (over 60 years of age) and study the effect of other personal factors such as height and body mass index on NCV.

Nerve conduction study among healthy malays. The influence of age, height and body mass index on median, ulnar, common peroneal and sural nerves.

Nerve conduction study is essential in the diagnosis of focal neuropathies and diffuse polyneuropathies. Age, height and body mass index (BMI) can affect nerve velocities as reported by previous studies. We studied the effect of these factors on median, ulnar, common peroneal and sural nerves among healthy Malay subjects. We observed slowing of nerve conduction velocities (NCVs) with increasing age and BMI (except ulnar sensory velocities). No demonstrable trend can be seen across different height groups except in common peroneal nerve.

Outcome of severe traumatic brain injury: comparison of three monitoring approaches.

The determination of cerebral perfusion pressure (CPP) is regarded as vital in monitoring patients with severe traumatic brain injury. Besides indicating the status of cerebral blood flow (CBF), it also reveals the status of intracranial pressure (ICP). The abnormal or suboptimal level of CPP is commonly correlated with high values of ICP and therefore with poor patient outcomes. Eighty-two patients were divided into three groups of patients receiving treatment based on CPP and CBF, ICP alone, and conservative methods during two different observation periods. The characteristics of these three groups were compared based on age, sex, time between injury and hospital arrival, Glasgow Coma Scale score, pupillary reaction to light, surgical intervention, and computerized tomography scanning findings according to the Marshall classification system. Only time between injury and arrival (p = 0.001) was statistically significant. There was a statistically significant difference in the proportions of good outcomes between the multimodality group compared with the group of patients that underwent a single intracranial-based monitoring method and the group that received no monitoring (p = 0.003) based on a disability rating scale after a follow up of 12 months. Death was the focus of outcome in this study in which the multimodality approach to monitoring had superior results.
