    The endothelium plays a crucial role in maintaining vascular homeostasis by producing several vasodilating factors, including nitric oxide (NO), prostacyclin (PGI2), and endothelium-dependent hyperpolarisation (EDH); however, the balance between endothelial relaxing and contracting factors is disrupted in disease states such as diabetes mellitus and hypertension. Most reported studies of endothelial dysfunction in diabetes focused on the actions of NO; however, there is accumulating evidence demonstrating that in addition to NO, PGI2 and EDH are likely to contribute to the vasodilatation of blood vessels. EDH plays an important role as a regulator of vascular tone and reactivity in resistance and conduit arteries of animal models and humans. PGI2 only plays a minimal role in endothelium-dependent vasodilatation but may serve as an important compensatory mechanism in conditions in which NO and EDH activities are decreased. Further studies are needed to determine the exact roles of EDH and PGI2 in the development of endothelial dysfunction and clinical vasculopathy in humans with type 1 and type 2 diabetes.

    Floods are considered an annual natural disaster in Kelantan. However, the record-setting flood of 2014 was a 'tsunami-like disaster'. Hospital Universiti Sains Malaysia was the only fully functioning hospital in the state and had to receive and manage cases from the hospitals and clinics throughout Kelantan. The experiences, challenges, and recommendations resulting from this disaster are highlighted from an emergency medicine perspective so that future disaster preparedness is truly a preparation. The history of how the health campus was constructed with the collaboration of Perunding Alam Bina and Perkins and Willis of Chicago is elaborated.

    Clival chordoma is a rare primary bone tumour that arises from the remnant of the notochord and typically occurs in older adults. Upon imaging, the tumour can be seen arising from the clivus and causes clival destruction. This usually provides insight for a diagnosis. Here we present a case of a non-enhancing, pre-pontine mass that was hypointense on T1W and hyperintense on T2W in an adolescent. No clival bone erosion was observed. Based on the age group, imaging findings, and lack of clival erosion, a provisional diagnosis of epidermoid cyst was made and the tumour was resected. This patient was eventually diagnosed with a clival chordoma based on histopathological examination.

    The detection rate of thyroid incidentalomas is increasing; in fact, as many as 2.3% of patients undergoing FDG PET-CT for other indications have been found to have thyroid incidentalomas. The risk of malignancy in these thyroid incidentalomas can be as high as 47%. The increased uptake and the focal uptake pattern of F-18 fluorodeoxyglucose (FDG) in the thyroid during positron emission tomography (PET)-computed tomography (CT), and the calcification of the thyroid incidentaloma, are associated with even higher risk of malignancy. We report a case of a lady undergoing FDG PET-CT for breast cancer staging but noted to have a calcified thyroid incidentaloma, which was proven to be follicular thyroid carcinoma.

    BACKGROUND: This study aimed to determine the intracellular (red blood cell (RBC)) magnesium levels in children with chronic bronchial asthma and to determine the relationship between the magnesium level and peak expiratory flow rate (PEFR), type of asthma treatment, and level of asthma control.
    METHODS: A cross-sectional study was conducted at the Paediatric Clinic, Sarawak General Hospital. A total of 100 children, aged 6-12 years with chronic bronchial asthma, were recruited according to the study criteria. Venous blood samples were obtained to measure the intracellular (RBC) magnesium level using the GBC Avanta Flame Atomic Absorption Spectrophotometer.
    RESULTS: Mean age was 8.57 (SD 1.18) years, and 63% of the participants were male. Mean duration of asthma was 62.2 (SD 32.3) months. A normal intracellular magnesium level was found in 95% of the participants, with a mean of 2.27 (SD 0.33) mmol/L. Two-thirds of the participants had a normal peak flow expiratory rate (> 80% of predicted value). About 85% were using both reliever and controller. Almost half of the participants (49%) had chronic asthma that was well-controlled. No significant relationship was found between magnesium level and age (r = -0.089, P = 0.379), gender (t = 0.64, P = 0.52), duration of asthma (r = -0.03, P = 0.74), PEFR (t = 0.41, P = 0.68), current level of asthma control (t = 0.02, P = 0.97), and current treatment (t = 0.414, P = 0.680).
    CONCLUSION: There was no significant intracellular magnesium deficiency in children with chronic bronchial asthma. There was no significant relationship between therapeutic medications used for treatment of children with chronic asthma and intracellular magnesium levels.

    An embryonic stem cell (ESC) is a good tool to generate neurons in vitro and can be used to mimic neural development in vivo. It has been widely used in research to examine the role of cell signalling during neuronal development, test the effects of drugs on neurons, and generate a large population of functional neurons. So far, a number of protocols have been established to promote the differentiation of ESCs, such as direct and indirect differentiation. One of the widely used protocols to generate neurons is through the spontaneous formation of multicellular aggregates known as embryonic bodies (EBs). However, for some, it is not clear why EB protocol could be the protocol of choice. EB also is known to mimic an early embryo; hence, knowing the similarities between EB and an early embryo is essential, particularly the information on the players that promote the formation of EBs or the aggregation of ESCs. This review paper focuses on these issues and discusses further the generation of neural cells from EBs using a well-known protocol, the 4-/4+ protocol.

    This study was done to correlate the occurrence of posterior capsule rupture among patients with pseudoexfoliation during phacoemulsification. This was a retrospective audit of patients who underwent phacoemulsification type cataract surgery from January 2011 to December 2012 in a tertiary hospital in Malaysia. Data was obtained from the National Eye Database (NED) of Malaysia. The data was analysed using SPSS version 21.0. By using logistic regression analysis, it was found that there was no significant increase in the occurrence of posterior capsule rupture among patients with pseudoexfoliation. Hence, we concluded that there was no correlation between the occurrence of posterior capsule rupture and the presence of pesudoexfoliation among patients who underwent phacoemulsification.

    Magnetoencephalography (MEG) has been extensively used to measure small-scale neuronal brain activity. Although it is widely acknowledged as a sensitive tool for deciphering brain activity and source localisation, the accuracy of the MEG system must be critically evaluated. Typically, on-site calibration with the provided phantom (Local phantom) is used. However, this method is still questionable due to the uncertainty that may originate from the phantom itself. Ideally, the validation of MEG data measurements would require cross-site comparability.

    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.

    Infective endocarditis (IE) is the one of the most important causes of increased mortality and morbidity among haemodialysis patients. The reason for this increasing prevalence of infection among these patients is the use of haemodialysis catheters during dialysis, as these patients are highly susceptible to infections that are easily transmitted via blood access points. The present case was a geriatric end stage renal disease (ESRD) patient who was readmitted to the hospital two days after her scheduled haemodialysis session with symptoms of nosocomial endocarditis. Her concurrent medical complications were hypertension, non-insulin dependent diabetes mellitus, and ischemic heart disease. Based on her previous medical history and current examination, the patient was suspected to have IE due to catheter related infection. The goal of therapy is to manage the comorbidities and infection by provision of appropriate treatment based on close monitoring of the patient condition.

    Papillary thyroid carcinoma (PTC) associated with familial adenomatous polyposis (FAP) is rare. It is usually associated with the cribriform-morular variant of PTC, with unusual patterns on detailed histology examination. This variant is known to have a good prognosis. Papillary thyroid carcinoma associated with FAP commonly occurs in females in their 30s and rarely in the elderly. We report a case of a 69-year-old female presenting with thyroid swelling and a history of FAP.

    Sekolah Menengah Sains Tengku Muhammad Faris Petra (SMSTMFP) and Sekolah Kebangsaan Kubang Kerian (3) (SKKK3) were selected by the Department of Neurosciences, Universiti Sains Malaysia (USM), in 2011 to be a 'school-based Neuroscience Club' via the 'Knowledge Transfer Programme (KTP) - Community' project. This community project was known as "The Brain Apprentice Project". The objectives of this project were to promote science and the neurosciences beyond conventional classroom teachings whilst guiding creativity and innovation as well as to assist in the delivery of neuroscience knowledge through graduate interns as part of the cultivation of neuroscience as a fruitful future career option. All of the planned club activities moulded the students to be knowledgeable individuals with admirable leadership skills, which will help the schools produce more scientists, technocrats and professionals who can fulfil the requirements of our religion, race and nation in the future. Some of the activities carried out over the years include the "My Brain Invention Competition", "Mini Brain Bee Contest", "Recycled Melody" and "Brain Dissection". These activities educated the students well and improved their confidence levels in their communication and soft skills. The participation of the students in international-level competition, such as the "International Brain Bee", was one of the ways future professionals were created for the nation. The implementation of Neuroscience Club as one of the organisations in the school's cocurriculum was an appropriate step in transferring science and neuroscience knowledge and skills from a higher education institution, namely USM, to both of the schools, SMSTMFP and SKKK3. The club members showed great interest in all of the club's activities and their performance on the Ujian Pencapaian Sekolah Rendah (UPSR) or Primary School Achievement Test and Sijil Pelajaran Malaysia (SPM) or Malaysian Certificate of Education examinations improved tremendously.

    The workplace environment has a great influence on employees' health. Job dissatisfaction has been widely recognised as a workplace stressor that can influence employees' psychological and physical health statuses. However, job satisfaction is a multi-dimensional concept, and it is necessary to investigate its different facets and their unique consequences. Therefore, the aim of this study was to assess the relationship between the nine facets of job satisfaction and psychological health and somatic complaints (i.e., sleep disorders, headache, gastro-intestinal and respiratory problems).

    The management of Enterocutaneous fistula (ECF) is challenging. It remains associated with morbidity and mortality, despite advancements in medical and surgical therapies. Early nutritional support using parenteral, enteral or fystuloclysis routs is essential to reverse catabolism and replace nutrients, fluid and electrolyte losses. This study aims to review the current literature on the management of ECF. Fistulae classifications have an impact on the calories and protein requirements. Early nutritional support with parenteral, enteral nutrition or fistuloclysis played a significant role in the management outcome. Published literature on the nutritional management of ECF is mostly retrospective and lacks experimental design. Prospective studies do not investigate nutritional assessment or management experimentally. Individualising the nutritional management protocol was recommended due to the absence of management guidelines for ECF patients.
