Mortality and injuries among Iranians in Iraq-Iran war: a systematic review.

BACKGROUND: The Iraq-Iran war was one of the longest conflicts in the twentieth century. The aim of our research was to review the incidence of mortality and injuries of the war. METHODS: A search strategy was designed and run in Medline, EMBASE, Scopus, and Iranian databases including Scientific Information Database (SID), IranMedex, and Magiran. Also, searching grey literature, checking references, tracking citations, hand-searching of focused journals, and websites were utilized for retrieval of related studies. All of articles which studied epidemiology of mortality or injuries of the war were included. The excluding criteria were case reports, case series, laboratory researches, and nonoriginal studies. RESULTS: Fourteen articles out of 1751 primary results were selected to be included in the study. During the war (1980 - 1988), 188,015 to 217,489 Iranians were killed (about 70 people per day). The mean age of mortality was 23 years. Six thousand four hundred twenty-seven (2.9%) of those who died during the war were females. One thousand five chemical warfare victims died between 1983 and 1994. From 1985 through 1998, 82 veterans had successful suicides too. At the end of war, we had 398, 587 veterans who needed follow- up. Among them, there were 52,000 chemical warfare victims. Between 1988 and 2003, 1400 people died and 2313 injured due to landmines and unexploded ordnances in five border provinces. CONCLUSION: The war caused a lot of mortalities and morbidities in our country. Now, 24 years after the war, many physically, mentally, and chemically injured victims have remained. We suggest other studies about indirect impacts of the war on societies, families, friends, and affiliates of the victims.

Mortality in British military participants in human experimental research into chemical warfare agents at Porton Down: cohort study.

OBJECTIVE: To investigate any long term effects on mortality in participants in experimental research related to chemical warfare agents from 1941 to 1989. DESIGN: Historical cohort study. Data sources Archive of UK government research facility at Porton Down, UK military personnel records, and national death and cancer records. Participants 18,276 male members of the UK armed forces who had spent one or more short periods (median 4 days between first and last test) at Porton Down and a comparison group of 17,600 non-Porton Down veterans followed to 31 December 2004. MAIN OUTCOME MEASURES: Mortality rate ratio of Porton Down compared with non-Porton Down veterans and standardised mortality ratio of each veteran group compared with the general population. Both ratios adjusted for age group and calendar period. RESULTS: Porton Down veterans were similar to non-Porton Down veterans in year of enlistment (median 1951) but had longer military service (median 6.2 v 5.0 years). After a median follow-up of 43 years, 40% (7306) of Porton Down and 39% (6900) of non-Porton Down veterans had died. All cause mortality was slightly greater in Porton Down veterans (rate ratio 1.06, 95% confidence interval 1.03 to 1.10, P<0.001), more so for deaths outside the UK (1.26, 1.09 to 1.46). Of 12 cause specific groups examined, rate ratios in Porton Down veterans were increased for deaths attributed to infectious and parasitic (1.57, 1.07 to 2.29), genitourinary (1.46, 1.04 to 2.04), circulatory (1.07, 1.01 to 1.12), and external (non-medical) (1.17, 1.00 to 1.37) causes and decreased for deaths attributed to in situ, benign, and unspecified neoplasms (0.60, 0.37 to 0.99). There was no clear relation between type of chemical exposure and cause specific mortality. The mortality in both groups of veterans was lower than that in the general population (standardised mortality ratio 0.88, 0.85 to 0.90; 0.82, 0.80 to 0.84). CONCLUSIONS: Mortality was slightly higher in Porton Down than non-Porton Down veterans. With lack of information on other important factors, such as smoking or service overseas, it is not possible to attribute the small excess mortality to chemical exposures at Porton Down.

Cancer morbidity in British military veterans included in chemical warfare agent experiments at Porton Down: cohort study.

OBJECTIVE: To determine cancer morbidity in members of the armed forces who took part in tests of chemical warfare agents from 1941 to 1989. DESIGN: Historical cohort study, with cohort members followed up to December 2004. DATA SOURCE: Archive of UK government research facility at Porton Down, UK military personnel records, and national death and cancer records. PARTICIPANTS: All veterans included in the cohort study of mortality, excluding those known to have died or been lost to follow-up before 1 January 1971 when the UK cancer registration system commenced: 17,013 male members of the UK armed forces who took part in tests (Porton Down veterans) and a similar group of 16,520 men who did not (non-Porton Down veterans). MAIN OUTCOME MEASURES: Cancer morbidity in each group of veterans; rate ratios, with 95% confidence intervals, adjusted for age group and calendar period. RESULTS: 3457 cancers were reported in the Porton Down veterans compared with 3380 cancers in the non-Porton Down veterans. While overall cancer morbidity was the same in both groups (rate ratio 1.00, 95% confidence interval 0.95 to 1.05), Porton Down veterans had higher rates of ill defined malignant neoplasms (1.12, 1.02 to 1.22), in situ neoplasms (1.45, 1.06 to 2.00), and those of uncertain or unknown behaviour (1.32, 1.01 to 1.73). CONCLUSION: Overall cancer morbidity in Porton Down veterans was no different from that in non-Porton Down veterans.

Sardasht-Iran cohort study of chemical warfare victims: design and methods.

BACKGROUND: Insights into long-term clinical consequences of sulfur mustard have emerged from some investigations but less is known about the basic and molecular mechanisms of these complications. Sardasht-Iran Cohort Study is a comprehensive historical cohort study on Sardasht chemical victims' population which was designed to find out the long-term complications of sulfur mustard exposure and the basic mechanisms underlying clinical manifestations. This paper describes the design and methodology of Sardasht-Iran Cohort Study. METHODS: In Sardasht-Iran Cohort Study, 500 individuals including 372 subjects from Sardasht, as the exposed group, and 128 subjects from Rabat, as the unexposed age-matched control group were evaluated. The exposed group was divided into two groups based on the severity of clinical complications at the time of exposure. Different samples including blood, sputum, saliva, tear, urine, and semen were collected for immunologic, hematologic, biochemical, and other laboratory analysis. Data were gathered from medical records, clinical examinations, laboratory tests, and questionnaires for psychological and lifestyle situations. CONCLUSION: The important distinctions setting this study apart from the previous ones are discussed. The Sardasht-Iran Cohort Study provides important information on various aspects of long-term consequences of sulfur mustard exposure. This database will provide a better position to suggest guidelines for the diagnosis, treatment, and prevention of delayed complications in the patients exposed to sulfur mustard.

The birth of nerve agent warfare: lessons from Syed Abbas Foroutan.

The author reviewed Farsi-language articles published recently by Dr. Syed Abbas Foroutan, which constitute the only firsthand clinical descriptions of battlefield nerve agent casualties in the world literature, and the author compares his comments with US and North Atlantic Treaty Organization (NATO) chemical casualty care doctrine. Foroutan's lessons learned reassure us that a robust medical evacuation system, coupled with timely and appropriate medical care of nerve agent poisoning, will save many more lives on future battlefields.

[Diagnostic and resuscitative aspects of pediatric nerve agent intoxication].

Chemical warfare and the use of nerve agents are still a threat to the civilian population in the 21st century. Modern history of chemical warfare began in 1915 in the battle of Ypres when German troops used chlorine against the French army. Since then, the arsenal of such agents has included asphyxiates, burn-causing and nerve paralytic agents. Nerve gases are considered the most dangerous of all chemical weapons with little known about the treatment of the civilian population especially children. Management of the civilian population injured by these agents may be a tremendous challenge, especially in children, due to lack of previous data regarding pediatric resuscitation. This review emphasizes resuscitation issues of the child who suffers from multiple trauma and nerve agent poisoning, mainly based on data from reports concerning episodic civilian exposure to organophosphates.

Precautions against biological and chemical terrorism directed at food and water supplies.

Deliberate food and water contamination remains the easiest way to distribute biological or chemical agents for the purpose of terrorism, despite the national focus on dissemination of these agents as small-particle aerosols or volatile liquids. Moreover, biological terrorism as a result of sabotage of our food supply has already occurred in the United States. A review of naturally occurring food- and waterborne outbreaks exposes this vulnerability and reaffirms that, depending on the site of contamination, a significant number of people could be infected or injured over a wide geographic area. Major knowledge gaps exist with regard to the feasibility of current disinfection and inspection methods to protect our food and water against contamination by a number of biological and chemical agents. However, a global increase in food and water safety initiatives combined with enhanced disease surveillance and response activities are our best hope to prevent and respond quickly to food- and waterborne bioterrorism.

Epidemiological study of sarin poisoning in Matsumoto City, Japan.

On the night of June 27, 1994, about 12 liters of sarin were released by terrorists in Matsumoto City, Japan. In order to investigate the epidemic, community-based questionnaire surveys were conducted. The subjects were all inhabitants (2052 people) living and staying in an area of 1050 meters from north to south and 850 meters from east to west including the sarin release site. Participants included 1743 people who answered the questionnaire at the first survey; those with symptoms were contacted for follow-up at four months and one year after the episode. The number of sarin victims were 471 persons. Muscarinic signs were common to all victims; nicotinic signs were only seen in severely affected victims. The geographical distribution of sarin victims was closely related to the direction of the wind. Three weeks after the intoxication, 129 victims still had some symptoms such as dysesthesia of the extremities. At that time, many victims had begun to experience asthenopia, which was even more frequent at four months. Although victims who felt sarin-related symptoms had decreased by a year, some still had symptoms such as asthenopia. Sarin released in a suburban area affected approximately 500 inhabitants living nearby; some still had symptoms a year after the intoxication.
