In Japan prior to 1990s, the national scale of head trauma statistics are only available by the Institute for Traffic Accident Research and Data Analysis. But these have limited data confined to traffic accident trauma by three classification system; death, severe trauma and minor trauma. In the need for easy accessibility of nationwide trauma data, the Japan Neurotrauma Data Bank (JNTDB) Committee was founded within the Japan Society of Neurotraumatology in 1997. The committee carried out the first pilot study involved by 10 medical institutions nationwide to evaluate traumatic brain injury in Japan. In project 1998 of JNTDB, original data sheet with 392 items including etiology of injury, pre-hospital care, initial treatment including neuro-intensive care unit, and surgical treatment, were created. As "Project 1998", the analysis results have been published in Japan Neurosurgical Society journal. The "Project 2004" was a clinical research on severe head injury cases that have been registered from July 2004 to June 2006. In 2005, one week study of the JNTDB was conducted to elucidate the actual status of head injury in Japan. In the history of during 15 years, JNTDB produced many clinical outputs: 10 presentations on neuroscience conferences and 69 review articles on the famous journals. Consideration of history and achievements of JNTDB suggests guidance to further refinement and direction of future development of Korean Neurotrauma Data Bank. Nationwide and international trauma data bank will be very valuable as a study guide or basic data of the project activities in the future.

OBJECTIVETo make an epidemiological analysis of the effect of environment on extremely severe road traffic crashes (RTCs).

METHODSEpidemiologic data of extremely severe RTCs associated with environmental factors, including weather, topography, road conditions and other traffic conditions in Mainland China during 2000-2001, were collected and analyzed.

RESULTS(1) During 2000-2001, there were 3365 extremely severe RTCs with 13666 deaths, 12204 injuries and a direct economical loss of 136 million RMB. (2) Most extremely severe RTCs occurred in fine weather days and in the daytime. The high occurrence sites were plain areas, horizontal and straight roads, Grade B and C roads, ordinary road segment, and asphalt, smooth and mixed roads. (3) Compared with other RTCs, extremely severe RTCs were more likely to happen under following conditions: on cloudy, snowing, misty and blustering days; in hill and mountainous areas; on crooked and sloping roads; on freeway, Grade A, B, and C roads; mixed roads; ordinary, bridge, narrow and transitional roads; sand and dirt-roads; without traffic control measures; night without lighting. (4) Extremely severe RTCs of mountainous area or crooked and sloping roads were most severe in terms of deaths and injures per crash.

CONCLUSIONSExtremely severe RTCs are closely related with environmental factors. Rational road programming, enhancing road establishment and improving road conditions are probably effective measures to reduce the road traffic injuries.

PURPOSERoad traffic accidents are one of main problems in Iran. Multiple factors cause traffic accidents and the most important one is sleepiness. This factor, however, is given less attention in our country. Road traffic accidents relevant to sleepiness are studied.

METHODSIn this cross-sectional study, all road traffic accidents relevant to sleepiness, which were reported by police, were studied in Tehran province in 2009.

RESULTSThe risk of road traffic accidents due to sleepiness was increased by more than sevenfold (odds ratio = 7.33) in low alertness hours (0:00-6:00) compared to other time of day. The risk of road traffic accidents due to sleepiness was decreased by 0.15-fold (odds ratio = 0.15) in hours with maximum of alertness (18:00-22:00) of circadian rhythm compared to other time of day.

CONCLUSIONThe occurrence of road traffic accidents due to sleepiness has significant statistical relations with driving during lowest point of alertness of circadian rhythm.

OBJECTIVETo date, there has been little information published on the death of rural road accident deaths. This study uses burden of injury method to explore a more accurate estimate of years of life lost due to road traffic crashes occurring over a four-year period in Guilan province, northern Iran.

METHODSRural road accident deaths from 2009 to 2013 were extracted from Iran's Forensic Medicine System, Death Registry System and Road Trauma Research center database.

RESULTSDuring the study period, the average years of life lost due to motor vehicle crashes was 13.8 per 1 000 persons, ranging from 11.9 during March 2011-2012 to 15.8 per 1 000 persons during March 2012-2013.

CONCLUSIONRoad accident deaths in 2013 remained at the same high level as in 2009. The information obtained from this study provides a new perspective on fatal road traffic crash victims in rural settings and show us that more attention is needed in this area.

The appearance of cars has raised materialistic civilization and living standard to an unprecedented level. Today, it is hard to imagine how we human beings can live without cars. Yet, motor vehicles can cause a great number of deaths and injuries as well as considerable economic losses, which have constituted the global burden. Understanding of the occurrence and development of road traffic injuries will contribute to the prevention and control of crash and to the implementation of "everybody has the right to enjoy health" proposed by WHO.
