Weathering the storm: children's long-term recall of Hurricane Andrew.

Children who experienced a highly stressful natural disaster, Hurricane Andrew, were interviewed within a few months of the event, when they were 3-4 years old, and again 6 years later, when they were 9-10 years old. Children were grouped into low, moderate, or high stress groups depending on the severity of the experienced storm. All children were able to recall this event in vivid detail 6 years later. In fact, children reported over twice as many propositions at the second interview as at the first. At the initial interview, children in the high stress group reported less information than children in the moderate stress group, but 6 years later, children in all three stress groups reported similar amounts of information. However children in the high stress group needed more questions and prompts than children in the other stress groups. Yet children in the high stress group also reported more consistent information between the two interviews, especially about the storm, than children in the other stress groups. Implications for children's developing memory of stressful events are discussed.

The effects of prenatal maternal stress on children's cognitive development: Project Ice Storm.

There exists considerable research on the effects of prenatal maternal stress on offspring. Animal studies, using random assignment to experimental and control groups, demonstrate the noxious effects of prenatal maternal stress on physical, behavioural and cognitive development. The generalizability of these results to humans is problematic given that cognitive attributions moderate reactions to stressors. In humans, researchers have relied upon maternal anxiety or exposure to life events as proxies for the stressors used with animals. Yet, the associations between maternal anxiety or potentially non-independent life events and problems in infants are confounded by genetic transmission of temperament from mother to child. We summarize the literature on prenatal maternal stress and infant cognitive development, leading to the conclusion that the human literature lacks the ability to separate the effects of the objective exposure to a stressor and the mother's subjective reaction. We then describe our prospective Project Ice Storm in which we are following 150 children who were exposed in utero to a natural disaster. We demonstrate significant effects of the objective severity of exposure on cognitive and language development at age two years with important moderating effects of the timing during pregnancy. The implications of our findings are discussed.

The social, cultural and political dimensions of contemporary war.

There have been more than 160 wars and armed conflicts since 1945, almost all in the Third World, and more than 50 currently. More than 90% of these are internal rather than between sovereign states. There has been a sixfold increase in the number of war refugees worldwide since 1970, who now number 1% of the global population. Ninety per cent of all casualties are civilians. A key element of modern political violence is the creation of states of terror to penetrate the entire fabric of grassroots social relations as a means of control. The valued institutions and ways of life of whole populations are routinely targeted for destruction. In the 1980s many such wars were played out on a terrain of subsistence economies. The back-drop is of environmental degradation, poverty, embedded social injustice, pressure on the nation-state, a global rise in food insecurity and a widening gulf between the wealthiest 20% and the poorest 20% in the world. The World Health Organization is warning of a health catastrophe, with life expectancy in the world's poorest countries falling by the year 2000 and one-third of the world's children undernourished. Understanding a complex and evolving set of causes and effects surrounding war is a considerable challenge to the international humanitarian field, not least the health professions. In recent years there has been a burgeoning interest in the psychological impact of the atrocities of war, and in trauma programmes based on Western psychological concepts and techniques. This individualistic focus risks neglecting the core issue: the role of a social world, invariably targeted in war and yet still embodying the capacity of survivor populations to manage their suffering, adapt and recover on a collective basis. Using the example of Mozambique, Guatemala and others, this paper will discuss the way in which contemporary war damages social and cultural forms, and the range of traditions, values and understandings which these carry. However, society and culture also engage actively with war, with changes in the social order that may come to outlast the violence itself. This paper will also pinpoint the quest for justice as an issue that may distinguish the subjective experience of war from those that arise after peacetime or natural disasters. The work of anthropologists, sociologists, historians and poets in both West and Third World, allied to the voices of survivors themselves, can help the humanitarian field to acquire a more richly textured understanding of the range of responses to war and atrocity, and outcomes over time.

Armed conflicts, health and health services in Africa. An epidemiological framework of reference.

Because of war, between the 1980s and early '90s Africa suffered about 5 million excess deaths and economic losses estimated at US $13 billion per year. In 1995, war was directly or indirectly affecting 550 million people in 35 countries. Besides violent deaths, injuries and disabilities, displacements of population increase the risk for acute respiratory infections, diarrhoeas, epidemics and parasitic disease. The risk for malnutrition and deficiencies is made worse by the loss of means of production, of food stocks, of commerce and by banditism. Military operations target water plants and health facilities as means of deliberately hurting civilians. Economic crisis curtails the budgets of the social sectors and, together with social distress, undermines national capacities. The delivery of health care is hampered right when hazards and vulnerabilities increase, with general greater risk of illness and death. With the cessation of hostilities, the need for curative and preventative health activities increases and is a matter of emergency, as equitable access to services is important for peace. Repatriation of refugees, demobilization of soldiers and demining require special health activities. War leaves behind new hazards and vulnerabilities such as landmines, wide availability of weapons, artificial concentrations of population, loss of national capacities and psychological disorders. All this interacts tragically with Africa's wider epidemiological realities of poverty, food insecurity, proneness to natural disasters and endemic diseases.

Interventions for post-traumatic stress disorder in children and adolescents.

Clinical features, epidemiology and aetiology of post-traumatic stress disorder (PTSD) are outlined. Treatment outcome studies involving children with PTSD who have survived traumatic accidents, natural disasters and child sexual abuse are reviewed. An evidence-based assessment and treatment protocol is outlined for children and adolescents with PTSD. Key components of effective treatment are psycho-education about trauma reactions, sustained exposure to trauma-related cues and memories until habituation occurs, coping skills training for children to help them manage anxiety and parent training to equip parents with the skills to help them facilitate their children's recovery.

Are regional hospital pharmacies prepared for public health emergencies?

INTRODUCTION: In the event of a major chemical, biological, radiological, nuclear, or explosive (CBRNE) attack or a natural disaster, large quantities of pharmaceuticals and medical supplies may be required with little or no warning. Pharmaceutical surge capacity for immediate response, before Strategic National Stockpile (SNS) supplies become available, remains a significant gap in emergency preparedness. To date, limited attempts have been made to assess collective regional hospital pharmaceutical response capabilities. In this project, we characterized the level of hospital pharmaceutical response preparedness in a major metropolitan region. METHODS: The Johns Hopkins Office of Critical Event Preparedness and Response (CEPAR) convened a collaborative partnership to assess hospital pharmaceutical response capabilities. A survey was developed to characterize pharmaceutical response preparedness to CBRNE threats. RESULTS: All 22 acute care hospitals in the Maryland region were sent pharmaceutical response surveys, and responses were received from 86% (19/22). Within the past year, 84% (16/19) of hospitals had implemented an exercise with pharmacy participation. More than half of the hospitals expect to receive assistance from the SNS in 48 hours or less. Seventy-four percent (14/19) of the hospitals reported an additional dedicated reserve supply for biological events, 74% (14/19) for chemical events, and 58% (11/19) for radiological events. CONCLUSION: Many hospitals in this metropolitan region have taken important steps toward enhancing pharmaceutical preparedness. However, hospitals generally remain underprepared for CBRNE threats and collectively have limited supplies of antibiotics to provide prophylaxis or treatment for hospital staff, their families, and patients in the event of a significant biological incident.

The synthetic evaluation model for analysis of flooding hazards.

BACKGROUND: Although many previous epidemiological studies have reported the incidence of diseases, mortality rate and economic losses after natural disasters, none of these studies has been comprehensive enough. Our aim was to establish a synthetic evaluation model (SEM) that can be used to analyze flood hazards. METHODS: Initial evaluation indicators were selected using systematic and literature data analysis. These indicators were tested with single or multiple variable analyses. Final evaluation indicators and their weights were determined using the Delphi procedure. We established a SEM of flood hazards using the hierarchy method and tested the model using jack-knife analysis. RESULTS: The SEM on flood hazards consists of 6 first-rank indicators and 24 second-rank indicators. First-rank indicators were: direct casualties (w = 0.2123), the increased incidence and prevalence rate of the disease (w = 0.1715), excess mortality rate (w = 0.1745), mental injury (w = 0.1038), epidemic focus expansion (w = 0.1572) and economic loss (w = 0.1807). The agreement of the model reached 98.2% tested with the jack-knife analysis. CONCLUSION: A SEM of flood hazards was established with an agreement of 98.2%, which can be used to evaluate the hazards, and assist public health-care workers provide appropriate flood disaster management.

Long term relations between earthquake experiences and coronary heart disease risk factors.

The authors analyzed the relations between a variety of earthquake-related experiences incurred in 1983-1984 (financial loss, evacuation, indices of disruption of social networks) and coronary heart disease risk factors (heart rate, blood pressure, total serum cholesterol) assessed in 1987 among 693 Italian male factory workers. Multivariate analyses (adjusting for age, body mass index, smoking, and educational level) revealed no long term relations between the quake-related experiences and blood pressure or cholesterol level. However, higher resting heart rates were observed for individuals who reported financial loss, increased distance from family/friends, or decreased visiting as a result of relocation after the quakes. Findings were unchanged after further adjustment for self-reported psychological distress (assessed using the global symptom index of the Symptom Checklist). These findings, while limited by the cross-sectional nature of the data, suggest that a number of psychosocial consequences of relocation due to a natural disaster are unrelated in the long term to coronary heart disease risk factors, except for small but significant differences in heart rate among individuals who have experienced financial loss and/or social network disruptions.

Public health impacts of floods and chemical contamination.

INTRODUCTION: Flooding accounts for about 40 per cent of all natural disasters that occur worldwide. In 2002-2003 many counties in England experienced severe floods. Floods are particularly important in public health terms as they may have multiple environmental consequences. METHODS: Details of floods reported to Chemical Hazards and Poisons Division, London [CHaPD(L)] were analysed and a literature review was undertaken to identify published reports of flood-related chemical incidents that have had an impact on public health. RESULTS: Epidemiological evidence shows that chemical material may contaminate homes and that in some cases flooding may lead to mobilization of dangerous chemicals from storage or remobilization of chemicals already in the environment, e.g. pesticides. Hazards may be greater when industrial or agricultural land adjoining residential land is affected. Less evidence exists to support the hypothesis that flooding that causes chemical contamination has a clear causal effect on the pattern of morbidity and mortality following these flooding events. CONCLUSION: In the light of this evidence, a checklist/pro forma for public health response to and investigation of flooding events that may result in chemical contamination was needed. This is available from CHaPD(L).

Deep negative T waves and abnormal cardiac sympathetic image (123I-MIBG) after the Great Hanshin Earthquake of 1995.

The authors report the increased incidence of patients with deep negative T waves without Q wave after the Great Hanshin Earthquake of 1995. Subjects underwent cardiac metaiodobenzyl guanidine (123I-MIBG) imaging, 201Tl scintigraphy, and coronary angiography. Among 2,756 inpatients of the preceding 5-year period, 33 (1.2%) showed the deep negative T waves, whereas 6 of 94 (6.4%; P < 0.001) showed it after the earthquake. Four of six patients had an episode of chest pain. Cardiac metaiodobenzyl guanidine imaging revealed the extent defects in all six patients despite a minimal change of 201Tl image. In addition, cardiac metaiodobenzyl guanidine imaging washout rate was hastened not only in the defect area but also in the nondefect area, which suggested augmented sympathetic activation. Natural disasters can affect the frequency of deep negative T waves, which relate abnormal cardiac sympathetic imaging.

The puzzle of Fran: home healthcare in a hurricane.

A natural disaster in the form of Hurricane Fran resulted not only in stories of ingenuity and compassion, but in a major performance improvement (PI) process for the entire agency. Through this PI process we learned about ourselves as a home health agency and discovered ways to improve our performance. More importantly we discovered ways to improve patient tracking and care during a disaster.

Psychiatric comorbidity in children after the 1988 earthquake in Armenia.

OBJECTIVE: To determine current rates of posttraumatic stress disorder (PTSD), depressive disorder, and separation anxiety disorder (SAD) among children 1 1/2 years after the 1988 earthquake in Armenia; to determine current rates of comorbid PTSD and depressive disorder; and to assess the contribution of exposure, gender, loss of family members, and loss of residence. METHOD: Two hundred eighteen school-age children from three cities at increasing distances from the epicenter were evaluated using the Child Posttraumatic Stress Disorder Reaction Index, the Depression Self-Rating Scale, and the section on SAD from the Diagnostic Interview for Children and Adolescents. RESULTS: On the basis of these evaluations, high rates of current PTSD, depressive disorder, and their co-occurrence were found among victims residing in the two heavily impacted cities. SAD was comparatively less frequent, although symptoms of SAD had been pervasive throughout the region. Severity of posttraumatic stress and depressive reactions were highly correlated. Extent of loss of family members was independently correlated with each. CONCLUSION: After a catastrophic natural disaster, children are at risk for comorbid PTSD and secondary depression. Based on the findings, an interactive model is proposed of postdisaster psychopathology. Early clinical intervention is recommended to prevent chronic posttraumatic stress reactions and secondary depression.

Prevalence of posttraumatic stress disorder and major depressive disorder in Tibetan refugee children.

OBJECTIVE: In an exploratory survey the prevalence of posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) was estimated in children who escaped from Tibet and found refuge in Tibetan settlements in India. METHOD: As part of an exploratory mission of the international medical relief organization Doctors Without Borders (Medecins Sans Frontieres), 61 randomly selected children from four group homes of the Tibetan Children Village in Dharamsala, India, were interviewed for symptoms of PTSD and MDD. RESULTS: 11.5% of the children met DSM-IV criteria for PTSD, and the same proportion met criteria for MDD. Children who had arrived from Tibet more recently (in the previous 18 months) showed a tendency for greater prevalence of PTSD than children who had been refugees longer. CONCLUSION: Tibetan children who succeed in their journey into exile suffer levels of stress-related disorders comparable with those of children in war situations or those exposed to natural disasters. However, in this population, several protective factors may help reduce the level of distress over time.

Moral development and psychopathological interference in conscience functioning among adolescents after trauma.

OBJECTIVES: To compare moral development and psychopathological interference with conscience functioning (PI) among adolescents exposed to different degrees of earthquake-related trauma and to investigate the relationship of moral development and PI to exposure to trauma, severity of posttraumatic stress disorder (PTSD) symptoms, postearthquake adversities, and extent of loss of nuclear family members. METHOD: Adolescents (N = 193) from 2 cities at different distances from the epicenter were evaluated. The Stilwell Structured Conscience Interview was used to assess moral development and PI. Structured self-report instruments were used to obtain ratings of severity of earthquake-related trauma, posttraumatic stress symptoms, and postearthquake adversities. RESULTS: Adolescents in the city near the epicenter manifested advanced moral development as compared with their counterparts in the less affected city. Concomitantly, they endorsed responses indicating PI. Levels of PI were significantly correlated with severity of PTSD symptoms. CONCLUSION: In the aftermath of a catastrophic natural disaster, children assume greater responsibilities and confront a multitude of morally challenging interpersonal situations which may result in an advancement of their moral development. Yet, at the same time, PTSD symptoms and negative schematizations of self and others may give rise to disturbances in conscience functioning. The findings suggest that therapeutic consideration should be given to assisting children in integrating the horror of their traumatic experiences and the harshness of posttrauma adversities into an adaptive schema of good and evil in themselves and the world.

Community patterns of posttraumatic stress disorders.

This paper reports lifetime rates for posttraumatic stress disorder (PTSD) in two rural northwest communities. One community was affected by a major natural disaster, the eruption of Mt. St. Helens. Following an epidemiology study of this disaster, community-wide patterns of PTSD were identified. Disaster-related, combat, sexual assault, and all other types of PTSD are presented for men and women. Symptom patterns from these distinct PTSD stressors are compared along with concurrent psychiatric disorders. The findings are discussed with other studies that use a broader definition of disaster stress response syndromes. This comparison identifies a limitation of PTSD diagnostic criteria that may significantly underestimate community rates.

Avoidance and intrusion in posttraumatic stress disorder.

Longitudinal data from 290 firefighters who had completed questionnaires 4, 11, and 29 months after exposure to a natural disaster were used to examine the role of intrusive and distressing memories in the etiology of posttraumatic stress disorder. At 42 months, all those who were at risk of having developed a psychiatric disorder (N = 113) and a randomly selected comparison group (N = 34) who had never developed symptoms were interviewed using the Diagnostic Interview Schedule. The intrusion subscale score of the Impact of Events Scale accounted solely for the etiological link between the disaster and posttraumatic disorders. Avoidance had no direct relationship with the onset of symptoms and appeared to be a defensive strategy to contain the distress generated by the re-experiencing of the disaster, indicating the importance of separating these phenomena from disorder mood and arousal in posttraumatic stress disorder. An information processing model was validated using three different data sets, which suggests its robustness. Using cross-lagged panel correlations, a bidirectional relationship was demonstrated between disorder and intrusive recollections, suggesting that the intensity of recurring memories of a traumatic experience is as indicative of a disturbance of mood and arousal as the exposure to the trauma.

The April 8, 1998 tornado: assessment of the trauma system response and the resulting injuries.

BACKGROUND: On April 8, 1998, an F5 tornado touched down in two counties of Alabama producing a wide path of destruction. The presence of a regional trauma system in this area presents an opportunity to evaluate the effectiveness of the system in responding to the victims of this natural disaster. METHODS: Emergency room logs and the regional trauma system database were searched for all patients treated for injuries sustained from the tornado, and medical records were reviewed for demographic information, mode of transportation to hospital, injuries, treatment, and outcome. Fatalities were identified by means of the coroner's office. RESULTS: A total of 224 patients were evaluated at nine area hospitals, of whom 63 (28%) required admission. There were 32 deaths: 30 persons were dead at the scene, and 2 patients subsequently died at Level I trauma centers. Among patients with nonfatal injuries, 39% were managed at Level I facilities, 46% at Level III facilities, and 15% at nontrauma facilities. Forty patients (55%) seen at Level I facilities required admission compared with 15 patients (17%) at Level III facilities and 8 patients (29%) at nontrauma facilities; Level I facilities also had the highest Injury Severity Score. Of patients requiring admission, 83% were transported by emergency medical services; these patients also had the highest Injury Severity Score. CONCLUSION: The regional trauma system facilitated appropriate and efficient triage to system hospitals, routing the most severely injured patients to the Level I centers without overwhelming them with the more numerous, less severely injured patients.

Physical symptoms of chronic fatigue syndrome are exacerbated by the stress of Hurricane Andrew.

This study examined the effects of Hurricane Andrew on physical symptoms and functional impairments in a sample of chronic fatigue syndrome (CFS) patients residing in South Florida. In the months after Hurricane Andrew (September 15-December 31, 1992), 49 CFS patients were assessed for psychosocial and physical functioning with questionnaires, interviews, and physical examinations. This sample was made up of 25 CFS patients living in Dade county, a high impact area, and 24 patients in Broward and Palm Beach counties, areas less affected by the hurricane. Based on our model for stress-related effects on CFS, we tested the hypothesis that the patients who had the greatest exposure to this natural disaster would show the greatest exacerbation in CFS symptoms and related impairments in activities of daily living (illness burden). In support of this hypothesis, we found that the Dade county patients showed significant increases in physician-rated clinical relapses and exacerbations in frequency of several categories of self-reported CFS physical symptoms as compared to the Broward/Palm Beach county patients. Illness burden, as measured on the Sickness Impact Profile, also showed a significant increase in the Dade county patients. Although extent of disruption due to the storm was a significant factor in predicting relapse, the patient's posthurricane distress response was the single strongest predictor of the likelihood and severity of relapse and functional impairment. Additionally, optimism and social support were significantly associated with lower illness burden after the hurricane, above and beyond storm-related disruption and distress responses. These findings provide information on the impact of environmental stressors and psychosocial factors in the exacerbation of CFS symptoms.
