Natural disasters, both expected and unexpected, usually cause widespread injuries and destruction with a large number of survivors, including children. Several studies have shown that children may develop posttraumatic stress disorder after exposure to disasters such as an earthquake.
Once a very slowly developing country in a Southeast Asia region, Malaysia has undergone considerable change over the last 20 years after the government changed its focus from agriculture to developing more industry and technology. The well-known "Vision 2020," introduced by the late Prime Minister, set a target for the nation to be a developed country in the Asia region by the year 2020. As the economy and standard of living have improved, the demand from the public for a better health care system, in particular, emergency medical services (EMS), has increased. Despite the effort by the government to improve the health care system in Malaysia, EMS within the country are currently limited, best described as being in the "developing" phase. The Ministry of Health, Ministry of Education, Civil Defense, and non-governmental organizations such as Red Crescent and St. John's Ambulance, provide the current ambulance services. At the present time, there are no uniform medical control or treatment protocols, communication systems, system management, training or education, or quality assurance policies. However, the recent development of and interest in an Emergency Medicine training program has gradually led to improved EMS and prehospital care.
Introduction The Comprehensive Healthcare (CHC) module was developed to introduce pre-clinical medical and pharmacy students to the concept of comprehensive healthcare. This study aims to explore their shared learning experiences within this module. Methodology During this module, medical and pharmacy students conducted visits to patients' homes and to related community-based organisations in small groups. They were required to write a reflective journal on their experiences regarding working with other professions as part of their module assessment. Highly scored reflective journals written by students from the 2011/2012 academic session were selected for analysis. Their shared learning experiences were identified via thematic analysis. We also analysed students' feedback regarding the module. Results Analysis of 25 selected reflective journals revealed several important themes: 'Understanding of impact of illness and its relation to holistic care', 'Awareness of the role of various healthcare professions' and 'Generic or soft skills for inter-professional collaboration'. Although the primary objective of the module was to expose students to comprehensive healthcare, the students learnt skills required for future collaborative practice from their experiences. Discussion The CHC module provided early clinical exposure to community-based health issues and incorporated some elements of inter-professional education. The students learnt about the roles of other healthcare professions and acquired soft skills required for future collaborative practice during this module.
A study was carried out on the concentration of REEs (Dy, Sm, Eu,Yb, Lu, La and Ce) that are present in the core marine sediments of East Malaysia from three locations at South China Sea and one location each at Sulu Sea and Sulawesi Sea. The sediment samples were collected at a depth of between 49 and 109 m, dried, and crushed to powdery form. The entire core sediments prepared for Instrumental Neutron Activation Analysis (INAA) were weighted approximately 0.0500 g to 0.1000 g for short irradiation and 0.1500 g to 0.2000 g for long irradiation. The samples were irradiated with a thermal neutron flux of 4.0×10(12) cm(-2) s(-1) in a TRIGA Mark II research reactor operated at 750 kW. Blank samples and standard reference materials SL-1 were also irradiated for calibration and quality control purposes. It was found that the concentration of REEs varies in the range from 0.11 to 36.84 mg/kg. The chondrite-normalized REEs for different stations suggest that all the REEs are from similar origins. There was no significant REEs contamination as the enrichment factors normalized for Fe fall in the range of 0.42-2.82.
A study was carried out on the distribution and enrichment of trace elements in the core marine sediments of East Malaysia from three stations at South China Sea and one station each at Sulu Sea and Sulawesi Sea. Five stations of sediment cores were recovered and the vertical concentration profiles of six elements namely Br, Cs, Hf, Rb, Ta, and V were determined using the instrumental neutron activation analysis. The enrichment factor, geoaccumulation index and the modified degree of contamination were used to calculate the anthropogenic and pollution status of the elements in the samples. Except for Cs and Hf, which by the enrichment factor are categorized from minimum enrichment to moderate enrichment in all stations and for V and Rb in Sulu Sea and Sulawesi Sea, which are categorized minimum enrichment, other elements are found to be no enrichment at all stations. The geoaccumulation index of Hf in one station shows moderately polluted and for other elements are unpolluted. However, the modified degree values of all samples are less than 1, suggesting very low contamination of elements found in all the stations.
Hand grenade explosion is a rare occasion in our local community. Most of us have seen or heard about the injuries only from the TV news or newspaper. We report two cases of bomb blast injury that occurred in an army camp in September 2000. These case studies illustrate the clinical presentations of hand grenade blast injures that present with multiple organ involvement. We would like to share our experience in managing such cases in a busy emergency department and highlight the outcome of those two cases. Certain issues pertaining to the complexity of the injuries and mass casualty management are also highlighted.
Medical standby is the provision of emergency medical care and first aid for participants and/or spectators in a pre-planned event. This article describes the framework and the demographics of a medical standby at the 4(th) National Youth Camping and Motivation Program in Pasir Puteh, Kelantan from 30(th) July until the 3(rd) August 2004. The framework of the medical team is described based on the work process of any medical stand by. A medical encounter form was created for the medical standby defining the type of case seen (medical or trauma), name, age, race and diagnosis of the patient. We concluded that interagency collaboration during the initial planning and during the event itself is needed to ensure the smooth running of the medical standby. Most of the medical encounters were minor illnesses which are similar to previous studies and there was no case transferred to the hospital during that period.
The present study aimed to assess the effects of anthropogenic activities on the heavy metal levels in the Langat River by transplantation of Corbicula javanica. In addition, potential ecological risk indexes (PERI) of heavy metals in the surface sediments of the river were also investigated. The correlation analysis revealed that eight metals (As, Co, Cr, Fe, Mn, Ni, Pb and Zn) in total soft tissue (TST) while five metals (As, Cd, Cr, Fe and Mn) in shell have positively and significantly correlation with respective metal concentration in sediment, indicating the clams is a good biomonitor of the metal levels. Based on clustering patterns, the discharge of dam impoundment, agricultural activities and urban domestic waste were identified as three major contributors of the metals in Pangsun, Semenyih and Dusun Tua, and Kajang, respectively. Various geochemical indexes for a single metal pollutant (geoaccumulation index (I geo), enrichment factors (EF), contamination factor (C f) and ecological risk (Er)) all agreed that Cd, Co, Cr, Cu, Fe, Mn, Ni and Zn are not likely to cause adverse effect to the river ecosystem, but As and Pb could pose a potential ecological risk to the river ecosystem. All indexes (degree of contamination (C d), combined pollution index (CPI) and PERI) showed that overall metal concentrations in the tropical river are still within safe limit. River metal pollution was investigated. Anthropogenic activities were contributors of the metal pollution. Geochemical indexes showed that metals are within the safe limit.
Disaster is a sudden event that associated with ecological changes, disruption of normal daily activities, destruction of infrastructures, loss of properties, and medical disabilities. In disaster, there is a mismatch between available resources and patients need for healthcare service. During flood disaster, the victims were predisposed to different type of illnesses for various reasons such as inadequate supply of clean water, poor sanitation or drainage system, unhealthy foods, and over-crowded relief centers. Mobile clinic is an option for delivering medical care for the disaster victims who often have a difficulty to access to the medical facilities. In this article we would like to share our experiences during the provision of humanitarian services for flood victims at District of Muar Johor. Common illnesses among the flood victims at visited relief centers and advantages of Mobile Medical Relief Team were also highlighted and discussed.
N-Methyl-3, 4-methylenedioxyamphetamine (MDMA), or ecstasy is a recreational drug of abuse. It is a synthetic substance that affects the body's systems, which its mechanism of action and treatment should be more investigated. MDMA provides an immediate enjoyable feeling by stimulating the release of neurotransmitters, such as dopamine and serotonin in the brain. Unfortunately, abnormal regulation of the brain neurotransmitters, as well as the increased oxidative stress causes damage to the brain neurons after the MDMA exposure. Only a few studies have been done regarding its treatment. Thus, the treatment of MDMA complications should be further explored mainly by targeting its mechanism of action in the neurotransmitter systems. Hence, this study presents a short review regarding the recent findings on the role of neurotransmitters to cause MDMA neurotoxicity. The results will be useful for future research in elucidating the potential treatment based on the targeted mechanisms to treat the neurotoxic effects of MDMA.
This retrospective study attempted to identify the pattern of ambulance calls for the past two years at the Hospital Universiti Sains Malaysia (HUSM) and Hospital Kota Bharu (HKB). This study will provide a simple method of acquiring information related to ambulance response time (ART) and to test whether it met the international standards and needs of the client. Additionally, this paper takes into account the management of emergency calls. This included ambulance response time, which was part of Emergency Medical Services (EMS) episode: onset of ART, which started when details like phone number of the caller, exact location of the incident and the nature of the main complaint had been noted. ART ended when the emergency team arrived at the scene of incident. Information regarding ambulance calls from the record offices of HUSM and HKB was recorded for the year 2001 and 2002, tabulated and analyzed. There was a significant difference in the total number of calls managed by HUSM and HKB in the year 2001. It was noted that 645 calls were managed by HUSM while 1069 calls were recorded at HKB. In the year 2002, however, HUSM led with 613 extra numbers of calls as compare to HKB with 1193 numbers of calls. The pattern of ambulance calls observed is thought to possibly be influenced by social activities like local festivities, school holidays and the seasons. Further, it is observed that no studies were previously undertaken to compare the ART at both the HUSM and HKB to that of the international standards. In fact, a literature review undertaken so far showed no similar studies have been done for the whole Malaysia.
