Objective： To compare fatalities and injuries in road traffic crashes （RTC） in Iran with other countries. Methods： Data were obtained from national health sources of Iran. These data included population number, registered motor-vehicles number, number of RTCs and consequent fatalities and injuries from 1997 to 2006. Results： RTC fatality and injury rates increased from 1997 to 2005, but decreased in 2006. The overall men/women ratio in the RTC fatalities was 4.2：1. High RTC fatality rate of 39 per 100 000 population in Iran was almost the same as some other developing countries. In Iran, RTC fatalities in recent years were almost twice as much as the highest rate among the European countries. Conclusions： This investigation shows that in spite of reduction of RTC fatality in Iran in 2006, it is still one of the highest in the world. Moreover, this paper describes the state of RTC-related parameters in a developing country in comparison with the developed countries.

The studied subject is about subsidence coefficient of mirages and dynamic storage volume of Karstic springs in Khorram Abad in West of Iran. Subsidence coefficient indicates ability of groundwater discharge and hydrologic properties of the environment;meaning effective porosity and transfer coefficient of springs. In general, in developed Karstic zones, each direct line of subsidence curve indicates a discharge regime. Obtained results from the study show that subsidence branch of Golestan, Motahari, Niloofar (changaei), Navekech, Dore Robat mirages have subsidence coefficient with mild slope and low value, which demonstrate passage of water through a seams system at the karst springs. Q and whirlpool stone mirages have two subsidence coefficients, which indicate passage of water through two seam systems in Karstic environment of springs. According to obtained results, process of changes in subsidence branch in these mirages has had at the first a mild slope and low discharge coefficient and in continue, its discharge would be declined with sharper slope and high discharge coefficient. In order to estimate dynamic storage volume of springs, MAILET general equation is applied, which is suitable for subsidence branch of hydrographs of centralized springs discharge. Following, dynamic storage volume of studied springs is analyzed and obtained results are presented in this study respectively.

Multiple variables can influence triage decision in multiple trauma. Recognition of priorities and selection of the destination can be successfully achieved by field triage and individualized clinical judgment. This narrative review summarizes the new options and protocols for transport of injured subjects. There are four levels of emergency medical providers including first responders and three levels of emergency medical technicians. Two distinct accepted protocols for transport are known as scoop and run and treat and then transfer. The former provides mini- mum lifesaving treatment at the scene of accident followed by transferring the patient（s） as soon as possible, and thelatter mainly emphasizes the need for complete stabilization as a prerequisite for safe transport. The destination and mode of transport are selected according to clinical capa- bilities of the receiving hospital, transfer time from the scene to the facility, patient＇s medical condition, accessibility of the scene, and weather. Two common methods of transfer are ground transport, including various type of ambulances, and air medical transport, i.e. helicopter and airplane.

目的：测定春季角结膜炎患者和一级亲属中相对其他过敏的患病率。方法：本前瞻性研究自1999-04/2008-03 9a间在520名春季角结膜炎的患者中进行。所有的年龄、性别、春季角结膜炎类型、其他伴随患者和/或其亲属的超敏反应的各种类别的信息记录在问卷调查表并用统计学分析。结果：520名患者中,男369例（71.0%）,女151例（29.0%）。患者的平均年龄为15.3岁（6 -30岁）。242例（46.5%）曾在自己或其一级亲属中有春季角结膜炎或其他类型超敏反应的历史。在这些阳性病史病例中,68例（28.1%）有过敏性皮炎,51例（21.1%）（其亲属）春季结膜炎,46例（19.0%）哮喘,29例（12.0%）过敏性鼻窦炎,24例（10.0%）药物过敏,14例（5.8%）特应性皮炎,6例（2.5%）过敏性鼻炎,4例（1.6%）有花粉热的历史。结论：不少春季角结膜炎患者和/或其亲属有其他由IgE介导的过敏或其他类型。哮喘、药物引起的过敏和其他过敏在这些患者中普遍。患者的亲属中春季角结膜炎比率高,因此它可能是由于疾病的遗传起源。

A 24-year-old male was transferred to the emergency department while being in the state of quadriplegia with a history of performing Parkour sport, which is also called double front flip. Neurological examination revealed that the patient＇s muscle power was 0/5 at all extremities. The patient did not show any sense of light touch or pain in his extremities. In radiological studies, cervical spine X-ray and CT scan images showed C4-C5 subluxation with bilateral locked facets and spinal cord injury. The results of this very rare case study revealed that exercising Parkour sport without taking into account safety standards could result in irreversible injuries to the cervical spinal cord with fatal outcome.

Objective： The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function. Methods： The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers. Results： Currently, various organizations are involved in prevention, management and rehabilitation of injuries, but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement, hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure （regarding staff, maintenance, financial resources）, it is not yet established in our system of trauma care. Conclusions： It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.
