Ionizing radiation can cause acute as well as chronic and late illnesses, and is a well-known health hazard. Its use by terrorists and nations in the form of a non-conventional weapon is no longer impossible. The release of radioactive materials with the accompanying contamination and radiation has the potential of causing serious medical problems. In analyzing the different radiologic terrorism scenarios, a scheme is proposed for the triage and evacuation of injured, contaminated and non-contaminated casualties from the scene itself as well as from the periphery. Knowledge, plans and drills will lessen the impact of those potential attacks and prepare us to respond to such events.

Atropine is the drug of choice for treatment of organophosphate (OP) nerve agent and insecticide intoxication and has been used for this indication for several decades. Adverse reactions to atropine may occur, and are of two types: toxic and allergic. Toxic reaction, the most common form, results from the anti-muscarinic effects of the drug. Since it is most probably related to interpersonal variation in sensitivity to atropine, toxic effects may appear at the usual therapeutic doses. The second type, allergic reaction, includes local manifestations, usually after the administration of eyedrops, and systemic reaction in the form of anaphylaxis. Since most patients manifest only a mild reaction, allergy testing is not performed and the prevalence of allergy to atropine is therefore not known. Severe allergic reaction to atropine is rare, as evidenced by the small number of case reports in the literature despite the drug's extensive use. Alternative anti-muscarinic drugs recommended for OP poisoning include glycopyrrolate and scopolamine. Glycopyrrolate is a peripheral anti-muscarinic drug that has been studied in comparison to atropine for many clinical indications, while scopolamine is an anti-muscarinic drug with both peripheral and central effects. An acceptable alternative regimen for patients with proven allergy to atropine is a combination of glycopyrrolate with centrally active drugs such as benzodiazepines or scopolamine.

Recent events have significantly increased concern about the use of biologic and chemical weapons by terrorists and other countries. Since weapons of mass destruction could result in a huge number of casualties, optimizing our diagnostic and therapeutic skills may help to minimize the morbidity and mortality. The national demands for training in medical aspects of nuclear, biologic and chemical warfare have increased dramatically. While Israeli medical preparedness for non-conventional warfare has improved substantially in recent years especially due to extensive training programs, a standardized course and course materials were not available until recently. We have developed a core curriculum and teaching materials for a 1 or 2 day modular course, including printed materials.

Background: The majority (n = 445) of the Israeli and Palestinian fatal victims of the El Aqsa Intifada was examined at the National Center of Forensic Medicine in Tel Aviv. Analysis of the trauma sustained and the anthropologic profile of both the victims and the perpetrators elucidates the trends and contrasts them with the phenomenon in the past.
Objectives: The purpose of the forensic investigation of mass casualty incidents is manifold: establishing the minimal number of individuals involved, identifying the victims and perpetrators, collecting material evidence, and determining the modus operandi.
Methods: The postmortem examination includes external description of the bodies and their injuries, photo-documentation, and sampling of tissues. Radiography, dental examination, and a ten-print card of each cadaver are also recorded.
Results: The modus operandi of the current Intifada is somewhat different from that of the previous wave of terrorism and includes more road shootings and vehicular terrorism. In addition, three suicide bombers using explosive devices detonated within crowded areas were young women, and the age of the perpetrators has increased from up to 35 years to individuals as old as 47, thus greatly enlarging the potential number of suicide terrorists. Virologic and biologic tests have been introduced to examine the tissues of the suicide bombers since they are possible sources of contagion to the wounded victims.
Conclusion: The results of the medico-legal investigation of victims and perpetrators of terrorism enable us to establish the modus operandi and the profile of potential perpetrators, which can help in the prevention of similar attacks. Documentation of the different types of injuries in fatal victims of explosion and shooting contributes to improving the awareness of the medical staff treating the wounded of similar attacks. Further investigation into the reliability of virologic and biologic tests conducted on postmortem tissue is recommended.

Background: During a period of 13 months - 1 October 2000 to 31 October 2001 – 586 terror assault casualties were treated in the trauma unit and emergency department of Hadassah University Hospital (Ein Kerem campus); 27% (n = 158) were hospitalized and the rest were discharged within 24 hours.
Objectives: To analyze the special requirements of a large number of victims who received treatment during a short period.
Methods: Data were attained from the main admitting office and the trauma registry records. Analysis was conducted of: age, gender, mechanism of injury, anatomic site of injury, Injury Severity Score (ISS), and length of stay.
Results: Males comprised 81% of the hospitalized patients. The majority of the injuries (70%) were due to gunshot wounds and 31% of the hospitalized patients were severely injured (ISS ≥ 16). Twelve patients died, yielding a mortality rate of 7.5%.
Conclusion: The nature of the injuries was more complex and severe than trauma of other etiologies, as noted by the mean length of stay (10.2 vs. 7.2 days), mean intensive care unit stay (2.8 vs. 0.9 days), and mean operations per patient (0.7 vs. 0.5). The mean insurance cost for each hospitalized terror casualty was also higher than for other trauma etiologies (US$ 3,200 vs. 2,500).

Background: The ear is the most frequent organ affected during an explosion. Recognition of possible damage to its auditory and vestibular components, and particularly the recovery time of the incurred damage, may help in planning the optimal treatment strategies for the otologic manifestations of blast injury and preventing deleterious consequences.
Objective: To report the results of the oto-vestibular initial evaluation and follow-up of 17 survivors of a suicidal terrorist attack on a municipal bus.
Methods: These 17 patients underwent periodic ear inspections and pure tone audiometry for 6 months. Balance studies, consisting of electronystagmography (ENG) and computerized dynamic posturography (CDP) were performed at the first time possible.
Results: Complaints of earache, aural fullness and tinnitus resolved, whereas dizziness persisted in most of the patients. By the end of the follow-up, 15 (55.6%) of the eardrum perforations had healed spontaneously. Hearing impairment was detected in 33 of the 34 tested ears. Recovery of hearing was complete in 6 ears and partial in another 11. ENG and CDP were performed in 13 patients: 5 had abnormal results on CDP while the ENG was normal in all the patients. The vertigo in seven patients resolved in only one patient who was free of symptoms 1 month after the explosion.
Conclusion: Exposure to a high powered explosion in a confined space may result in severe auditory and vestibular damage. Awareness of these possible ear injuries may prevent many of the deleterious consequences of such injuries.

Background: The threat to the individual’s physical integrity and well-being as well as to those of significant others, the disruption of normal patterns of life, and property losses make wartime a highly stressful condition.
Objectives: To assess the level of psychological distress in primary care attenders in a district of Jerusalem (Gilo) that experienced long-term exposure to gunfire.
Methods: A self-administered questionnaire exploring emotional distress (anxiety and depression symptoms), fire exposure, patterns of help-seeking behavior, and prescription of sedative or hypnotic drugs was administered to a sample of 125 consecutive attenders to a general practitioner during a 10 week period in the autumn of 2001. Eighty-four attenders residing in Gilo were compared with 41 attenders residing in neighborhoods that had not been under fire. T-tests and Mann-Whitney two-sample tests were used to determine statistical significance of differences.
Results: The mean distress score was significantly higher among the Gilo residents than among their counterparts in other neighborhoods (1.1 ± 0.8 vs. 0.8 ± 0.5, t = 1.73, P <0.01); 15.5% of the former reported probable clinically significant distress. Emotional distress was associated with periods of intensive gunfire exposure, psychological care-seeking behavior, and the prescription of sedative or hypnotic drugs. No significant differences in distress levels were found between those living in zones of Gilo that were at differential gunfire risk, nor between those whose houses and cars were or were not damaged.
Conclusions: War-related life events would seem to be associated with elevated emotional distress. A motivated primary care physician could easily and reliably ascertain the attenders’ psychological status and identify those requiring psychological support. These identification and intervention stages are facilitated if the specialized services are community-based.

Background: Organophosphates (OP) are frequently used as insecticides in the household and in agricultural areas, thus posing a risk for accidental exposure.
Objectives: To describe the characteristics, clinical course and outcome of 97 patients admitted to emergency rooms with a diagnosis of acute OP poisoning.
Methods: The clinical details of 97 patients were collected from 6 different hospitals in Israel. Diagnosis of intoxication was based on clinical findings, butyrylcholinesterase levels and, in several cases, the material brought to the hospital. Demographic, intoxication and clinical data were analyzed.
Results: The study group comprised 64 men and 33 women whose age range was 1–70 years old (mean 19.8 ± 17.1); more than one-third of the patients were less than 10 years old. Accidental exposure was the cause of intoxication in 51.5% of the patients, and suicide in 20.6% of exposures. Intoxication occurred at home in most patients (67%), and the route of intoxication was oral in 65% of them. The patients arrived at the hospital 20 minutes to 72 hours after intoxication. Nine patients were asymptomatic; 53 presented with mild intoxication, 22 with moderate, and 13 had severe intoxication, 5 of whom died. There was a direct correlation between the degree of inhibition of butyrylcholinesterase levels and the severity of intoxication. Treatment included decontamination and antidotal medication. Duration of hospitalization ranged between 1 and to 14 days (average 2.9 days).
Conclusions: Organophosphates may cause severe morbidity and mortality. Medical staff should therefore be aware of the clinical manifestations and the antidotal treatment for this poisoning.

The chemical warfare agent sulfur mustard affects primarily the eyes, skin and respiratory tract. Of these, ocular injury is the most immediate and distressing. Learning to recognize ocular injury enables the treating physician to provide early and suitable treatment, which will reduce complications and allow the victim a rapid recovery.
