A randomized controlled trial of a forgiveness intervention program with female acid attack survivors in Pakistan.

Despite the traumatic effects of acid violence on its victims, treatment options are very limited. The present study was aimed at examining the efficacy of a forgiveness intervention with female survivors of acid attack violence in Pakistan. Female acid attack victims in Pakistan were randomized to either a forgiveness group (n = 8) or a treatment-as-usual (TAU; n = 8) control group. The forgiveness group received twice-a-week forgiveness sessions for 4 months, whereas the TAU group either received typical psychological treatment sessions for acid attack victims or no treatment. All participants were assessed on their levels of forgiveness, anger, anxiety, depression, and hope four times prior to the 4-month intervention period, twice after the intervention period, and once at the 1-year follow-up. Posttreatment, the forgiveness intervention group showed greater improvement in hope, anger, anxiety, and depression when compared with the TAU group. Upon further examinations, both groups improved on forgiveness from pretreatment to posttreatment, but the forgiveness group had a higher baseline. From pretreatment to the 12-month follow-up, the forgiveness group, when compared with the TAU group, showed greater improvement in all areas except for depression. This is the first study that examined the effects of a forgiveness intervention for acid attack victims in Pakistan. Results showing the improvement posttreatment as well as over a 1-year period posttreatment are encouraging.

A Detoxification Intervention for Gulf War Illness: A Pilot Randomized Controlled Trial.

Approximately 30% of the 700,000 US veterans of the 1990-1991 Persian Gulf War developed multiple persistent symptoms called Gulf War illness. While the etiology is uncertain, several toxic exposures including pesticides and chemical warfare agents have shown associations. There is no effective medical treatment. An intervention to enhance detoxification developed by Hubbard has improved quality of life and/or reduced body burdens in other cohorts. We evaluated its feasibility and efficacy in ill Gulf War (GW) veterans in a randomized, waitlist-controlled, pilot study at a community-based rehabilitation facility in the United States. Eligible participants (n = 32) were randomly assigned to the intervention (n = 22) or a four-week waitlist control (n = 10). The daily 4-6 week intervention consisted of exercise, sauna-induced sweating, crystalline nicotinic acid and other supplements. Primary outcomes included recruitment, retention and safety; and efficacy was measured via Veteran's Short Form-36 (SF-36) quality of life, McGill pain, multidimensional fatigue inventory questionnaires and neuropsychological batteries. Scoring of outcomes was blinded. All 32 completed the trial and 21 completed 3-month follow-up. Mean SF-36 physical component summary score after the intervention was 6.9 (95% CI; -0.3, 14.2) points higher compared to waitlist control and 11 of 16 quality of life, pain and fatigue measures improved, with no serious adverse events. Most improvements were retained after 3 months. The Hubbard regimen was feasible, safe and might offer relief for symptoms of GW illness.

Long-Term Effects of Chemical Warfare on Post-traumatic Stress Disorder, Depression, and Chronic Medical Conditions in Veterans.

We investigated the association between exposure to chemical warfare and chronic mental/physical conditions. This was a secondary analysis of data from a case-control study on Iranian male veterans. Participants with neuropsychiatric disorders other than depressive/anxiety disorders, anatomical defects, or malignancies were excluded. Compared to non-exposed veterans, exposed veterans demonstrated significantly higher odds of PTSD [OR (95% CI) = 5.23 (1.98-13.85)], hypertension [OR (95% CI) = 5.57 (1.68-18.48)], coronary heart disease [OR (95% CI) = 6.8 (1.62-28.49)], and diabetes [OR (95% CI) = 3.88 (1.35-11.16)], and marginally higher odds of moderate to severe depressive symptoms [OR (95% CI) = 2.21 (0.93-5.28)]. This study provides preliminary evidence on association of exposure to chemical warfare with long-term mental disorders as well as chronic medical conditions.

Long-term neurological and neuropsychological complications of sulfur mustard and Lewisite mixture poisoning in Chinese victims exposed to chemical warfare agents abandoned at the end of WWII.

In August 2003, 44 victims were poisoned by chemical warfare agents (CWAs) leaked from five drums that were excavated at a construction site in Qiqihar, Northeast China. The drums were abandoned by the former Japanese imperial army during World War II and contained a mixture of Sulfur mustard (SM) and Lewisite. We carried out a total of six regular check-ups between 2006 and 2014, and from 2008 we added neurological evaluations including neuropsychological test and autonomic nervous function test in parallel with medical follow-up as much as was possible. Severe autonomic failure, such as hyperhidrosis, pollakiuria, diarrhoea, diminished libido, and asthenia appeared in almost all victims. Polyneuropathy occurred in 35% of the victims and constricted vision occurred in 20% of them. The rates of abnormal response on cold pressor test (CPT), active standing test (AST), Heart rate variability (CVR-R), performed in 2014, were 63.1%, 31.6%, and 15.9%, respectively. On neuropsychological testing evaluated in 2010, a generalized cognitive decline was observed in 42% of the victims. Memories and visuospatial abilities were affected in the remaining victims. Finally, a 17-item PTSD questionnaire and the Beck Depression Inventory evaluated in 2014 revealed long-lasting severe PTSD symptoms and depression of the victims. Our findings suggest that an SM/Lewisite compound have significant adverse consequences directly in cognitive and emotional network and autonomic nervous systems in the brain.

Spirituality: a key factor in coping among Iranians chronically affected by mustard gas in the disaster of war.

The present study aimed to explore the approach used by Iranians chronically affected by mustard gas in the disaster of war to cope with their chronic illness complications. A qualitative approach was adopted using content analysis of unstructured interviews carried out with 20 patients in a medical center in Tehran and an outpatient clinic in the North West of Iran. Two main themes that emerged from the study were "religious sentiment" and "patriotism". The subthemes that emerged were "divine will", "illness as a means of absolving sin", "saying prayers in the anticipation of divine rewards", "defending the motherland" and "self-sacrifice as a source of pride". To sum up, spirituality was recognized as a key factor among the participants in accepting and coping with their chronic illness complications.

A psychochemical weapon considered by the Warsaw Pact: a research note.

Contrary to widespread rumours during the Cold War era, little, if any, evidence existed in the scientific literature to support the view that the Soviet Union or its Warsaw Pact allies considered the use of psychochemical weapons militarily. The Hungarian State Archives have recently opened up declassified records of Hungary's State Defence Council meetings held between 1962 and 1978. Materials submitted to the Council include reports about the coordinative meetings of the Warsaw Pact military medical services. Research into possible countermeasures against psychotropic drugs is listed as a research priority assigned to Hungary in 1962. Hungary rejected this task in 1963, but joined the ongoing project again in 1965. Methylamphetamine was produced in Budapest for use as an experimental model of such weapons. Within the context of contemporary western research, this drug was considered to be an effective interrogation tool. Similarly to the CIA, Hungary also failed to develop an antidote against it and the project was terminated, fruitlessly, in 1972. These documents serve as evidence that a Warsaw Pact forum had, in fact, been considering a psychochemical weapon as a "warfare agent."

The long-term psychosocial impact of a surprise chemical weapons attack on civilians in Halabja, Iraqi Kurdistan.

War and human rights abuses contribute to increased prevalence of posttraumatic stress (PTS) disorder and low social functioning among populations affected. There is relatively little evidence, however about the long-term mental health impact of war on general populations. We examined the prevalence of PTS symptoms and poor social functioning in Halabja, Iraqi Kurdistan, 18 years after a chemical attack on civilians in that town. We systematically sampled 291 persons representative of the population of Halabja from the city emergency department and 4 outpatient clinical sites. PTS symptoms and poor social functioning were common. After adjustment for covariates, female gender, older age, and cumulative exposure to multiple traumas, all were associated with higher PTS scores and worse social functioning. Exposure to human rights abuses and warlike conditions seem to continue to be risks for psychiatric and social dysfunction even decades after the initial incident.

Psychological effects of chemical weapons: a follow-up study of First World War veterans.

BACKGROUND: Chemical weapons exercise an enduring and often powerful psychological effect. This had been recognized during the First World War when it was shown that the symptoms of stress mimicked those of mild exposure to gas. Debate about long-term effects followed the suggestion that gassing triggered latent tuberculosis. METHOD: A random sample of 103 First World War servicemen awarded a war pension for the effects of gas, but without evidence of chronic respiratory pathology, were subjected to cluster analysis using 25 common symptoms. The consistency of symptom reporting was also investigated across repeated follow-ups. RESULTS: Cluster analysis identified four groups: one (n=56) with a range of somatic symptoms, a second (n=30) with a focus on the respiratory system, a third (n=12) with a predominance of neuropsychiatric symptoms, and a fourth (n=5) with a narrow band of symptoms related to the throat and breathing difficulties. Veterans from the neuropsychiatric cluster had multiple diagnoses including neurasthenia and disordered action of the heart, and reported many more symptoms than those in the three somatic clusters. CONCLUSIONS: Mild or intermittent respiratory disorders in the post-war period supported beliefs about the damaging effects of gas in the three somatic clusters. By contrast, the neuropsychiatric group did not report new respiratory illnesses. For this cluster, the experience of gassing in a context of extreme danger may have been responsible for the intensity of their symptoms, which showed no sign of diminution over the 12-year follow-up.

Psychiatric issues in toxic exposures.

Military, occupational, and environmental events can cause toxic injuries that require psychiatric diagnosis and treatment. This article reviews the psychiatric effects of neurotoxins, including nerve gases, ionizing radiation, insecticides, heavy metals, solvents, and other toxic agents. Diagnostic considerations and clinical tests for further evaluation of the numerous psychiatric conditions and symptoms caused by toxic exposures are discussed.

Anxiety, depression, and posttraumatic stress in Iranian survivors of chemical warfare.

CONTEXT: In the 1980-1988 Iran-Iraq War, extensive use of chemical weapons resulted in high rates of morbidity and mortality. While much is known about the physical consequences of chemical warfare, there is a paucity of information about the long-term effects of chemical attacks on mental health. OBJECTIVE: To assess the long-term psychological impact of chemical warfare on a civilian population. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional randomized survey conducted in July 2004 of 153 civilians in 3 towns exposed to warfare in northwestern Iran: Oshnaviyeh (low-intensity conventional warfare), Rabat (high-intensity conventional warfare), and Sardasht (both high-intensity conventional warfare and chemical weapons). MAIN OUTCOME MEASURES: Full or partial posttraumatic stress disorder (PTSD) diagnosis, anxiety symptoms, and depressive symptoms were assessed using Farsi versions of the Clinician-Administered PTSD Scale, Hamilton Scale for Anxiety, and Beck Depression Inventory, respectively. RESULTS: Overall participation rate was 93%. Respondents had a mean age of 45 years and were all of Kurdish ethnicity. Among individuals exposed to both high-intensity warfare and chemical weapons, prevalence rates for lifetime PTSD, current PTSD, major anxiety symptoms, and severe depressive symptoms were 59%, 33%, 65%, and 41%, respectively. Among the low-intensity warfare group, the corresponding rates were 8%, 2%, 18%, and 6%, respectively, while intermediate rates were found among those exposed to high-intensity warfare but not to chemical weapons (31%, 8%, 26%, and 12%, respectively). Compared with individuals exposed to low-intensity warfare, those exposed to both high-intensity warfare and chemical weapons were at higher risk for lifetime PTSD (odds ratio [OR], 18.6; 95% confidence interval [CI], 5.8-59.4), current PTSD (OR, 27.4; 95% CI, 3.4-218.2), increased anxiety symptoms (OR, 14.6; 95% CI, 6.0-35.6), and increased depressive symptoms (OR, 7.2; 95% CI, 3.3-15.9). Exposure to high-intensity warfare but not to chemical weapons was also significantly associated with lifetime PTSD (OR, 5.4; 95% CI, 1.7-17.6), compared with those in the low-intensity warfare group. Further, compared with individuals exposed to high-intensity warfare alone, those exposed to both high-intensity warfare and chemical weapons were at higher risk for lifetime PTSD (OR, 3.4; 95% CI, 1.5-7.4), current PTSD (OR, 6.2; 95% CI, 2.0-20.1), increased anxiety symptoms (OR, 5.6; 95% CI, 2.5-12.6), and increased depressive symptoms (OR, 3.7; 95% CI, 1.8-7.2). CONCLUSION: Exposure to chemical warfare is an extreme traumatic event that has long-lasting adverse consequences on mental health.

Why people believe they were exposed to biological or chemical warfare: a survey of Gulf War veterans.

The study sought to understand better how people come to believe they have been exposed to biological and chemical warfare. We conducted telephone interviews with 1,009 American veterans (65% response rate) deployed and not deployed to the Gulf War, a conflict during which there were credible threats that such warfare could be used. Only 6% of non-Gulf War veterans reported exposure to biological or chemical warfare, but most of Gulf War veterans reported exposure (64%). The majority of these were unsure whether the exposure was chemical or biological in nature. The most commonly reported exposure indicators were receiving an alert from the military and having physical symptoms. Veterans who were certain of the type of exposure (biological or chemical) were more likely to recall having been told by the military and to recall physical symptoms. Future communications with soldiers and the general public about biological and chemical warfare may need to emphasize the uncertain nature of such risk information. Evaluations of exposure diagnostic technologies should take into account the problem of people initially believing, but not later discounting, false positive results.

Association between lower P300 amplitude and smaller anterior cingulate cortex volume in patients with posttraumatic stress disorder: a study of victims of Tokyo subway sarin attack.

Previous investigations of auditory P300 event-related potentials have provided electrophysiological evidence for attentional problems in patients with posttraumatic stress disorder (PTSD). The present study sought to evaluate the relationship between P300 deficits and underlying brain morphological abnormalities in never-treated, comorbidity-free patients with PTSD following the Tokyo subway sarin attack. Out of 47 victims recruited, 8 victims with PTSD and 13 victims without PTSD were identified. Correlational analyses were performed between auditory P300 amplitude at Pz electrode site elicited in an oddball task and anterior cingulate gray matter volume that was shown to be reduced in our previous study using voxel-based morphometry on magnetic resonance imaging. Victims with PTSD showed significantly lower amplitudes of P300 compared with victims without PTSD, and the lower P300 amplitudes at Pz were significantly associated with higher avoidance/numbing scores in the PTSD group. Furthermore, in the PTSD group only, the P300 amplitudes showed a trend toward significant positive correlation with voxel densities of the anterior cingulate cortex gray matter. These results provide the first evidence that electrophysiological deficits of controlled attention observed in patients with PTSD may be linked to underlying brain morphological abnormalities.

Mass violence and early mental health intervention: a proposed application of best practice guidelines to chemical, biological, and radiological attacks.

Based on past episodes, there will be psychological sequelae to chemical, biological, and radiological attacks. Some of the psychological morbidity should be able to be ameliorated through planning and appropriate early intervention. Key components of early intervention are illustrated following a hypothetical scenario of a bomb and anthrax threat near the Pentagon. Many of these components, such as monitoring clear, consistent messages about health risks, are provided by physicians or politicians, not mental health providers, but have a serious impact on the mental health of the population. We hope that this scenario and the principles of response will prove useful to planners of emergency preparedness and responders in the case of an actual attack.

The psychological dimension of chemical, biological, radiological and nuclear (CBRN) terrorism.

Terrorism is an increasing feature of the World Scene. In the UK, our perspective has changed from a largely Ireland focused one to a more international view. The United States of America are, for the first time, seen as major terrorist targets. We are now "at war with terrorism". The medical aspects of terrorism have been extensively discussed in this journal and elsewhere, this article specifically addresses the psychological consequences of the use of terror weapons.

Reactions of psychiatric inpatients to the threat of biological and chemical warfare in Israel.

In the months before the Second Gulf War, the threat of biological and chemical warfare led many Israelis to experience significant stress and mood changes. In this study, we investigated whether this threat affected the subjective mood and behavior of inpatients with schizophrenia and compared the results with effects noted in their clinical staff. Subjects were evaluated at two points in time-2 months before the war and on day 1 of the war-with a specially designed questionnaire and with the Spielberger Scale for Trait Anxiety. Although the responses of the two groups did not differ radically before the war, on the first day of war, significant differences were noted, with patients demonstrating increases in anxiety and level of concern. Both groups reported similar effects on their mood. Patients were more concerned about the potential for the outbreak of World War III, whereas staff were more concerned about economic effects. Female subjects in both groups demonstrated greater anxiety and mood changes after the outbreak of war compared with before the war. Effects observed on the patients may be related to the decreased coping threshold resulting from their illness, which renders psychotic patients more vulnerable to any acute stressor; however, effects on the staff members should not be ignored.

Chemical warfare and the Gulf War: a review of the impact on Gulf veterans' health.

It is unlikely that Gulf War veterans are suffering chronic effects from illnesses caused by chemical warfare nerve agent exposure. Extensive investigation and review by several expert panels have determined that no evidence exists that chemical warfare nerve agents were used during the Gulf War. At no time before, during, or after the war was there confirmation of symptoms among anyone, military or civilian, caused by chemical warfare nerve agent exposure. However, studies of Gulf War veterans have found belief that chemical weapons were used, significantly associated with both severe and mild-moderate illnesses. The psychological impact of a chemical warfare attack, either actual or perceived, can result in immediate and long-term health consequences. The deployment or war-related health impact from life-threatening experiences of the Gulf War, including the perceived exposure to chemical warfare agents, should be considered as an important cause of morbidity among Gulf War veterans.

[Chemical and biological terrorism: psychological aspects, and guidelines for psychiatric preparedness].

Chemical or biological terror may cause mass casualties, but the major damage of such a threat is related mainly to psychological terror. Anxiety and panic that accompany chemical or biological threat, may affect mass populations, disrupt their lives, and enormously increase the demands from the medical systems. In the case of real attack, such an increased demands may be critical, especially to the functional ability of hospitals. The Israeli experience, during the Persian Gulf war, concerning preparations to chemical attacks at the national level, was unique in its nature. In addition, the Scud missiles attacks, accompanied with non-conventional threat, supplied valuable information on the populations behavior, and on the needed preparations for similar threats. In the case of chemical or biological threat or attack, the main task of the psychiatrist is to treat stress and anxiety casualties. At the same time, he should be aware of the possibility that the psychological & behavioral symptoms may reflect organic brain damage due to the pathogenic agent, and that such a differential diagnosis may be life saving for the patient. Stress casualties will be referred from the ER, and treated by the mental health team, at a specifically designed "center for stress casualties". In addition, the psychiatrist will consult the medical teams, or sometimes directly intervene, with combined casualties, at other locations of the hospital. At the regional or community level, one should plane and exercise deployment and activation of multi-professional teams, including mental health, in existing installations designed for screening, treatment, and temporary containment of casualties. It is recommended that the head of the local authority, will be responsible for the preparations and activation of this formation. A planned and rational usage of the media may have a critical influence on the ability of the authorities to manage the crisis situation and on shaping the behavior of the population. In certain scenarios, the media may even serve as the main tool for calming and instructing the people being isolated at their homes.
