[Changes in the immune system of the victims of the action of the factors in the accident at the Chernobyl Atomic Electric Power Station. Their manifestations, nature and the possible sequelae].

The hypothesis is formulated, which explains genesis of long-lasting disturbances in the immune system of the persons affected by factors of Chernobyl disaster. Immunological alterations which are displayed at the late time after action of radiation in doses 0.5 Gy or lower are not a result of direct damage of the cells of immune system by irradiation. Their development is more probably a result of appearance of some systemic conditions and factors in affected organism--such as hormonal disbalance and especially autoantibodies of different specificities, including those reactive with thymic epithelial cells. Autoantibodies of the last type induce the decrease of thymic hormone secretion which results in functional deficiency of T lymphocytes. This chain of events is similar to those occurring in aging and does not directly causes development of the clinical displays of immunodeficiency. Only irradiation in doses of 4-6 Gy or higher inducing the structural damage of thymic microenvironment can rouse the long-lasting T cell immunodeficiency with the clinical manifestations.

The World Trade Center attack. Eye witness: observations of a physician on the outside looking in.

Having personally witnessed the destruction at the World Trade Center on 11 September 2001, this paper presents my personal feelings and observations as an observer of both disaster and terror. Aside from the unimaginable horror as a result of the carnage, a feeling of helplessness was particularly prominent due to the inability to be able to care for casualties since most victims were fatalities. The passage of time has enabled a return to normalcy, however 'normalcy' carries a new definition due to the vastness of the tragedy and the sudden threat of bioterrorism and other weapons of mass destruction.

Critical incident stress debriefing (CISD) in a shipping company.

Critical incident stress debriefing (CISD) is a method used successfully to reduce suffering from stress-related ailments such as insomnia, depression, anger, headaches etc. The resources of the shipping company are very limited and, thus, networking with existing organizations and specialists is necessary to carry out CISD effectively. The present company model has been adopted to take into account various situations and levels of disaster. The model has been adopted at three levels of events:Level 1. Serious accidents on shore, sudden deaths, severe events and threats. Events involving one or only few persons. Level 2. Life-threatening occupational accidents on board ship, suicide of a workmate, sudden death and fire on board ship. Events involving one person or limited group of persons. Level 3. Disasters at sea. Severe events involving all or nearly all persons on board ship. Actions at different levels: Level 1: A leaflet describing CISD, situations where it would be appropriate and where it is available, is given to each sailor. The victim is encouraged to seek CISD from public health care centres, most of which have their own services in Finland. Level 2. Training of about 8 hours is carried out by an experienced crisis psychologist for supervisors and officers on board ship. After the training they are able to identify stressful situations. At each harbour, the shipping company has made agreements with experienced crisis psychologists to act as specialists and contact persons on shore. These nominated psychologists will initiate CISD actions when necessary. If they need extra manpower they will turn to other psychologists. Level 3. In such serious accidents, the company's own resources alone are insufficient to provide effective CISD. All available public and private resources will he needed (health care organizations, Red Cross, Church etc.).

The by-products generated during sarin synthesis in the Tokyo sarin disaster induced inhibition of natural killer and cytotoxic T lymphocyte activity.

More than 5000 passengers on Tokyo subway trains were injured by the nerve gas, sarin and its by-products. Analysis of phosphor-carrying metabolites of sarin and its by-products in urine samples from the victims suggested that they were exposed not only to sarin, but also by-products generated during sarin synthesis, i.e. diisopropyl methylphosphonate (DIMP) and diethyl methylphosphonate (DEMP). We suspected genetic after-effects due to sarin by-products, thus, we checked the frequency of sister chromatid exchange (SCE) and found that SCE was significantly higher in the victims than in a control group, and that DIMP and DEMP significantly induced human lymphocyte SCE in vitro. In the present study, to explore whether DIMP and DEMP, which induced a high frequency of SCE of lymphocytes, also affected the lymphocyte functions, we examined the effect of DIMP and DEMP on splenic natural killer (NK) and splenic cytotoxic T lymphocyte (CTL) activity in mice, and NK activity of human lymphocytes in vitro. We found that DIMP and DEMP significantly inhibited NK and CTL activity in a dose-dependent manner. The inhibition induced by DIMP was stronger than that by DEMP. The effect of DIMP and DEMP on the splenic NK activity of mice was stronger than on the splenic CTL activity, and the human lymphocytes is more sensitive to DIMP and DEMP than the splenocytes of mice.

A PHS pharmacist team's response to Hurricane Katrina.

PURPOSE: The challenges and victories that a team of Public Health Service (PHS) pharmacists experienced in establishing pharmacy operations at a federal medical station and conducting outreach missions are described. SUMMARY: The Gulf coast of Mississippi and southeast Louisiana were struck on August 29, 2005, by Hurricane Katrina, which caused widespread infrastructure damage, flooding, and loss of life. A team of 70 officers, which included 8 pharmacists, arrived on September 3 and 4 to establish a 480-bed federal medical station in an aircraft hangar at the naval air station (NAS) in Meridian, Mississippi. Numerous challenges were encountered, including identifying a secure space for a pharmacy, determining how to manage the immediate shortage of medications, devising a dispensing system specific to controlled medications, handling personal medications brought in by patients, and maintaining adequate pharmacy staffing to provide for hospital needs. Two outreach efforts were also undertaken. The first was to assist the NAS pharmacy department, which was overwhelmed with nearly 800 Navy and Coast Guard personnel who were displaced to the Meridian NAS. The second outreach effort was to augment the staff at a local free clinic in Meridian, which needed help to set up their clinic so they could handle the influx of hurricane victims who were arriving daily. CONCLUSION: A team of PHS pharmacists established a pharmacy, provided pharmaceutical care, and conducted outreach programs to aid victims of Hurricane Katrina.

Exposure and response to methyl isocyanate: results of a community based survey in Bhopal.

In the two weeks immediately after the Bhopal disaster a community based survey was carried out in a series of eight exposed and two non-exposed clusters of households. The primary concern was the effect of the gas (subsequently identified as methyl isocyanate) on the eyes of the victims but data were also sought on respiratory status and the first symptoms of the exposure. No case of blindness was encountered that could be attributed to the gas. The most frequent symptoms reported were burning of the eyes, coughing, watering of the eyes, and vomiting. Among these, the frequency of cough most closely followed the rate of death in the different clusters. Although much rarer overall, the frequency of reported diarrhoea appeared to bear a stronger relation to death rates. Reports of photophobia and the clinical finding of superficial interpalpebral erosion of the cornea were more frequent where the death rates were lower. This clinical and epidemiological picture is consistent with different effects of the gas at different doses (as estimated from distance from the factory).

Disaster down East: using participatory action research to explore intimate partner violence in eastern North Carolina.

In the aftermath of Hurricane Floyd in 1999, a Community Advisory Committee requested assistance from its university partners (University of North Carolina) to address stress and increased risk for intimate partner violence (IPV). Collected from 12 study work sites, baseline data indicated that IPV rates were higher among blue-collar women in eastern North Carolina than national population-based rates suggest. IPV victims reported higher levels of perceived stress, psychological distress, somatic complaints, and post-traumatic stress disorder (PTSD) symptoms than did nonvictimized coworkers. As for the relationship of the flood to IPV, no significant increase in IPV incidence occurred after the flood. Regardless of their flood experience, however, IPV victims consistently reported greater stress, PTSD symptoms, and somatic and psychological problems. Moreover, IPV victims may be at higher risk for stress-mediated chronic illnesses and for using negative coping behaviors. This study uses an established trusting relationship between researchers and community members to explore community needs and inform intervention design.

The 1983 Beirut Airport terrorist bombing. Injury patterns and implications for disaster management.

The casualty profile and results of the medical care provided for the survivors of the terrorist truck bombing of the U.S. Marine Corps facility in Beirut, Lebanon, in 1983 were reviewed to determine the factors that influenced casualty survival. This explosion resulted in 346 casualties, of whom 234 (68%) were immediately killed. The spectrum of injury was determined in 85 survivors using the Injury Severity Score (ISS). There were seven (6.3%) deaths among the 112 immediate survivors. All deaths occurred among the 19 (17%) victims who were critically injured (ISS greater than 15), giving a mortality in this population of 37 per cent. Six (86%) of the seven deaths were associated with an initial delay in treatment. Head injury was the most common fatal injury among both immediate fatalities (71.4%) and immediate survivors (57%). Thoracic injury and burns each accounted for 29 per cent of survivor deaths. Triage efficiency, as determined by the rates of overtriage (80%) and undertriage (0), did not appear adversely to affect mortality. Critical analysis of disasters such as this can contribute to improvements in preparation and casualty care in the event of future disasters.

Chemical incident planning: a review of the literature.

Chemical incidents cause problems for Accident and Emergency (A & E) departments which are different from those recognized in other major accidents. As well as possible trauma there is the added problem of contamination. A & E departments must be prepared for chemical disasters with a chemical incident plan, decontamination facilities and protective clothing for all staff involved. The plan should include how to protect the hospital from contamination and how to prevent its personnel from becoming secondary casualties. The results of a survey into the preparedness of inner London A & E departments were published in issue 6.2 of this journal, April 1998. On 20 March, 1995 a religious cult released a nerve gas (sarin) into the Tokyo subway system. More than 5500 people needed hospital treatment and 11 people died (Reuter News Service, 22 March, 1995). The hospitals were overwhelmed with casualties. Once chemical exposure of victims was suspected, clothing was removed and patients were showered. Stretcher patients were decontaminated by means of bed bathing and a change of bedclothes (Okumura et al 1996). Hospital contamination was a problem during this incident due to the delay in recognising chemical exposure. This resulted in staff contamination. Many lessons were learned from this disaster, including the need to be prepared for all eventualities. If a similar incident occurred in the London Underground system, it would be catastrophic. Underground staff, police, fire fighters, ambulance staff and the general public could all be contaminated before the chemical was identified. There could be mass casualties, including personnel in the emergency services. How would London A & E departments cope, faced with a chemical disaster such as this?

Hypercapnia increases core temperature cooling rate during snow burial.

Previous retrospective studies report a core body temperature cooling rate of 3 degrees C/h during avalanche burial. Hypercapnia occurs during avalanche burial secondary to rebreathing expired air, and the effect of hypercapnia on hypothermia during avalanche burial is unknown. The objective of this study was to determine the core temperature cooling rate during snow burial under normocapnic and hypercapnic conditions. We measured rectal core body temperature (T(re)) in 12 subjects buried in compacted snow dressed in a lightweight clothing insulation system during two different study burials. In one burial, subjects breathed with a device (AvaLung 2, Black Diamond Equipment) that resulted in hypercapnia over 30-60 min. In a control burial, subjects were buried under identical conditions with a modified breathing device that maintained normocapnia. Mean snow temperature was -2.5 +/- 2.0 degrees C. Burial time was 49 +/- 14 min in the hypercapnic study and 60 min in the normocapnic study (P = 0.02). Rate of decrease in T(re) was greater with hypercapnia (1.2 degrees C/h by multiple regression analysis, 95% confidence limits of 1.1-1.3 degrees C/h) than with normocapnia (0.7 degrees C/h, 95% confidence limit of 0.6-0.8 degrees C/h). In the hypercapnic study, the fraction of inspired carbon dioxide increased from 1.4 +/- 1.0 to 7.0 +/- 1.4%, minute ventilation increased from 15 +/- 7 to 40 +/- 12 l/min, and oxygen saturation decreased from 97 +/- 1 to 90 +/- 6% (P < 0.01). During the normocapnic study, these parameters remained unchanged. In this study, T(re) cooling rate during snow burial was less than previously reported and was increased by hypercapnia. This may have important implications for prehospital treatment of avalanche burial victims.

Psychosocial responses to biological and chemical terrorist threats and events. Implications for the workplace.

1. Both biological and chemical weapons (BCW) could potentially be used in future terrorist attacks on U.S. workplaces and communities. 2. Threats of BCW terrorism may lead to anxiety, adverse health effects, and the exacerbation of psychiatric symptoms and syndromes in workers and managers. 3. Actual BCW attacks will likely cause both acute and chronic mental disorders in a significant number of surviving victims who may also be employees or employers. 4. Occupational health nurses can help prevent or remediate maladaptive psychological responses by educating themselves and their work forces, assisting in a risk assessment of the workplace, understanding disaster planning, and assisting management in policy formulation and psychosocial triage.

[Post-traumatic psychosis: the contribution of an acute post-immediate trauma to a dynamic theorization].

SUMMARY: In his recent publication (2004), in which he favors the psycho-dynamic approach, M. Bertrand underlines the importance of traumatic matter at the heart of new clinical, methodological and epistemological challenges of psychopathology. TRAUMATIC PSYCHOSIS CONCEPT: Our contribution ("post-traumatic psychosis") comes within that prospect in reference to the semiology of traumas generated by extreme situations, such as the tsunami in South Asia (December 2004), the terrorist attacks in Madrid (March 2004) or the hostage taking in North Ossetia (September 2004). Four principle sets of themes lead us to suggest a traumatic psychosis when the person shows symptoms of a neurotic psychic structure: 1. There's no traumatic representation or psychic inscription of the event. Sideration (and its stupor-like confusion symptoms) or panic flight (together with hallucinations or acute delirious fits) often illustrate this first clinical aspect. 2. According to the psychodynamic frame of reference, psychic processes tend to ignore the pleasure/displeasure principle. They are governed by the "invasion" of affects of pain and compulsion to repeat. 3. The models of neurosis and psychic conflict are not efficient in the management of the "quota of affect" and the drive influence. 4. It would be necessary to add, from a psychopathological point of view, the appearance of temporary fits of mental confusion, self-destructive and autolysis behavior. CLINICAL FEATURES: The frame of reference of a DSM IV type "descriptive" psychopathology (ie acute Stress Disorder) seems to de inadequate to convey the implemented post traumatic stakes. If trying to soothe the symptoms is undeniably important, psychic disorganizations that generate a semiology that is essentially present in the symptomatology of the psychoses cannot be ignored. A first clinical approach makes it possible to specify the argumentation of our proposal: "a post-traumatic psychosis". It is supported by five main syndromic classes: 1) the symptoms are often more or less temporary delirious fits (delirious ideas or perceptions of a persecutory, cenesthetic or hypochondriac nature), mental confusion (oneiroid state, anxiety and stupor), phases of depersonalization and derealization, severe death pangs, serious physical disorders, divides close to schizophrenic-type dual personalities; 2) the adhesiveness marks the impossibility for the victims to keep away from a trauma. The objects are bound, persecuting and adhesive; 3) traumatic temporality imposes a factual and current omnipresence of the trauma. It destroys the temporal projections of the patient as well as an anamnesic reconstruction; 4) the "traumatic body" is not that of hysterical neurosis conversions. The somatic semiology marks operational-type functioning (P. Marty); 5) traumatic compliance doesn't work on the level of facilitations that lead to the formation of symptoms. The identity structure appears disorganized by the dismantling of the primary psychic envelopments. PSYCHOPATHOLOGICAL ASPECTS: A second theoretical approach makes it possible to promote this immediate psychotic-type post-traumatic psychopathology. Four considerations of fundamental psychopathology support our contribution: 1) Pictogramic inscription. The severe traumatism does not produce the polarity required for the process of "self-fathering" described by P. Aulagnier in connecting with original processes. Traumatic adhesiveness does not separate the victim from the trauma. It splits the necessary mediation spaces and distance for the emergence of representation processes. 2) Pain affect. The pain affect generated recalls the first experiences of the newborn, primitive agony and anaclitical collapse; the "narcissistic contract" is broken and the patient lives without a secure base or a sufficiently good and supporting psychic container (D.W. Winnicott). 3) Anxiety status. The anxiety is not of neurotic nature but truly annihilating. It is often similar to anxieties caused by disasters, psychoses due melancholy (H. Ey) or more "archaic" anxieties that have been observed in hebephrenic pathologies. 4) Body dismantling. The trauma results in "mute somatizations that cannot be symbolized" (M. Bertrand). They appear in sensory outward signs such as dermatosis, pruritus, diarrhea, hemorrhagic periods or persistent headaches for example. These two clinical and theoretical aspects of the severe forms of trauma confirm the unconscious traumatolytic aim of the victim's psychological destruction. The semiological forms most impervious to therapeutic processes seem to be, in reference to hostage-takings or terrorists acts, those where the patient was conformed with a trauma "that was not carried out" like mock hangings or executions. Suicidal dimension seems to be the ultimate recourse so as not to sink into insanity and to keep a subjective position when faced with barbarian figures.

Posttraumatic stress and change in lifestyle among the Hanshin-Awaji earthquake victims.

BACKGROUND: In 1995, Japan's Hanshin-Awaji area was severely damaged by a major earthquake. Lifestyle factors, sometimes associated with physical health and mortality, have also been known to be associated with mental health status. This report examines the relationship between the subsequent change in lifestyle and the psychological stress induced by the earth quake. METHOD: An investigation was made of 108 male inhabitants of Awaji Island as to their individual lifestyle before and after the great earthquake, any posttraumatic stress disorder (PTSD) symptoms, and their demographic variables. RESULTS: The mean PTSD score was higher in the worse lifestyle group than in the no/better lifestyle change group. Category B or D of PTSD scores were higher in the worse lifestyle group than in the no/better lifestyle change group. The percentage of subjects who lived in temporary public housing was higher in the worse lifestyle group than in the no/better lifestyle change group. CONCLUSIONS: Worse change in lifestyle might be associated with high PTSD score in victims of Hanshin-Awaji earthquake.
