Post-traumatic stress disorder in pre-school aged children after a gas explosion.

UNLABELLED: To evaluate the sensitivity of diagnostic criteria for post-traumatic stress disorder (PTSD) in pre-school aged children involved in a gas explosion, post-traumatic symptoms of the children were investigated four times after the accident, immediately, 10 days, 6 months, and 1 year later. Using symptoms at 6 months after the accident, sensitivity of diagnostic criteria was assessed by comparing the fourth edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and the alternative criteria for infants and young children [10]. In addition, the published Child Post-Traumatic Stress Disorder Reaction Index (CPTSD-RI) and its modified version proposed by us were also evaluated their sensitivity to rate the symptoms. Girls had a tendency to show more post-traumatic symptoms than boys. Although no children met DMS-IV criteria for PTSD, 8 children out of 32 were diagnosed as having PTSD with alternative criteria. With our modified CPTSD-RI, all eight children were decidedly more statistically distinguishable from those without PTSD than with original index. CONCLUSION: our data indicate that the sensitivity of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (4th edition) and the Child Post-Traumatic Stress Disorder Reaction Index in rating symptoms of pre-school aged children is not sufficient. The alternative criteria of the former and modified version of the latter would be the better choice in this age group.

Post-traumatic stress disorder after subarachnoid haemorrhage.

OBJECTIVE: Draw attention to the presence of post-traumatic stress disorder in aneurysmal subarachnoid haemorrhage patients. DESIGN: Case review of 28 patients referred to clinical neuropsychology via a neurosurgery out-patient clinic. METHOD: Clinical interview of patients presenting with anxiety related to their medical condition. RESULTS: In 50 per cent of patients anxiety was found to be the main presenting problem and 32 per cent of referred patients met the diagnostic criteria for post-traumatic stress disorder. CONCLUSION: The case review identified significant psychological morbidity in patients with good physical recovery. This requires detailed scientific evaluation in future studies of outcome.

Prevalence of post-traumatic stress disorder in fibromyalgia patients: overlapping syndromes or post-traumatic fibromyalgia syndrome?

OBJECTIVES: The primary aim of this study was to assess the frequency of post-traumatic stress disorder (PTSD) in patients with the fibromyalgia syndrome (FMS). The influence of gender on measures of PTSD in fibromyalgia (FM) patients also was examined. METHODS: Seventy-seven consecutive patients (40 women and 37 men) who fulfilled the criteria for FM were asked to complete questionnaires measuring the prevalence and severity of symptoms of PTSD, anxiety, and depression. The subjects were divided in 2 groups based on the presence or absence of PTSD symptoms. RESULTS: In this study, 57% of the FM sample had clinically significant levels of PTSD symptoms. The FM patients with PTSD reported significantly greater levels of avoidance, hyperarousal, reexperiencing, anxiety, and depression than did the patients without clinically significant levels of PTSD symptoms. The prevalence of PTSD among the FM patients in this study was significantly higher than in the general population. Women with FM and PTSD reported a greater number of past traumatic events than did their male counterparts. CONCLUSIONS: The results represent the first comprehensive study applying structured clinical assessment of trauma exposure and PTSD to a group of FM patients. This study shows a significant overlap between FM and PTSD, according to the currently accepted diagnostic criteria for each.

Affective and anxiety comorbidity in post-traumatic stress disorder treatment trials of sertraline.

Comorbidity of mood and anxiety disorders is common in patients suffering from post-traumatic stress disorder (PTSD). The current study evaluated the efficacy and tolerability of sertraline in a subgroup of PTSD patients suffering from anxiety or depression comorbidity. Two multicenter, 12-week, double-blind, flexible-dose US studies of adult outpatients from the general population with a DSM-III-R diagnosis of PTSD evaluated the safety and efficacy of sertraline (50 to 200 mg/d) compared to placebo in the treatment of PTSD. The total severity score of the Clinician-Administered PTSD Scale (CAPS-2) and the Davidson Trauma Scale (DTS) were used to examine the effect of comorbidity on treatment outcome. Among the combined 395 subjects enrolled in the two trials, 32.9% had a comorbid depressive diagnosis (no anxiety diagnosis), 6.3% had a comorbid anxiety disorder diagnosis (no depression), 11.4% had both a depression and anxiety disorder diagnosis, and 49.4% had no comorbidity. The correlation, at baseline, between Hamilton Depression Rating Scale (HAM-D) total score and the three CAPS-2 clusters was 0.37 for the re-experiencing/intrusion cluster, 0.52 for the avoidance/numbing cluster, and 0.45 for the hyperarousal cluster. Patients suffering from PTSD complicated by a current diagnosis of both depression and an anxiety disorder showed the highest baseline CAPS-2 cluster score severity. Patients treated with sertraline improved significantly (P <.05) compared to placebo on both the CAPS-2 and DTS whether or not they had a comorbid depressive or anxiety disorder. Sertraline was well tolerated. The presence of comorbidity was associated with a modest and mostly nonspecific increase in the side effect burden of approximately 10% to 20% on both study treatments. Patients suffering from dual depression and anxiety disorder comorbidity benefited from somewhat higher doses (147 mg v 125 mg; P =.08). Similarly, the presence of dual comorbidity resulted in a modest but nonsignificant increase in the mean time to response from 4.5 weeks to 5.5 weeks. We conclude that sertraline (50 to 200 mg/d) is effective and well tolerated in the treatment of PTSD for patients suffering from a current, comorbid depressive or anxiety disorders.

The University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index.

Over the past decade, the University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index has been one of the most widely used instruments for the assessment of traumatized children and adolescents. This paper reviews its development and modifications that have been made as the diagnostic criteria for post-traumatic stress disorder have evolved. The paper also provides a description of standard methods of administration, procedures for scoring, and psychometric properties. The Reaction Index has been extensively used across a variety of trauma types, age ranges, settings, and cultures. It has been broadly used across the US and around the world after major disasters and catastrophic violence as an integral component of public mental health response and recovery programs. The Reaction Index forms part of a battery that can be efficiently used to conduct needs assessment, surveillance, screening, clinical evaluation, and treatment outcome evaluation after mass casualty events.

Memory bias for faces that are perceived as hostile by crime victims with acute post-traumatic stress disorder.

The present study tested, and found support for, the hypotheses that crime victims with acute post-traumatic stress disorder have: (i) a general memory impairment for faces; and (ii) a memory bias for faces that they perceive as hostile, even when these faces are not arranged to show any hostile face expressions. It is suggested that crime victims with acute post-traumatic stress disorder perform worse on recognition memory due to impaired concentration, and that they allocate their limited attentional resources to the detection of hostility in others in order to avoid being victimized again. This produces a memory bias for perceived hostility even in relatively innocuous everyday interactions with others, which contributes to maintaining the sense of serious current threat that characterizes post-traumatic stress disorder.

Selectively reduced regional cortical volumes in post-traumatic stress disorder.

Different subterritories of anterior cingulate cortex (ACC) and adjacent ventromedial frontal cortex have been shown to serve distinct functions. This scheme has influenced contemporary pathophysiologic models of psychiatric disorders. Prevailing neurocircuitry models of post-traumatic stress disorder (PTSD) implicate dysfunction within pregenual ACC and subcallosal cortex (SC), as well as amygdala and hippocampus. In the current study, cortical parcellation of magnetic resonance imaging data was performed to test for volumetric differences in pregenual ACC and SC, between women with PTSD and trauma-exposed women without PTSD. The PTSD group exhibited selectively decreased pregenual ACC and SC volumes. These results are consistent with contemporary schemes regarding functional and structural dissection of frontal cortex, and suggest specific regional cortical pathology in PTSD.

Post-traumatic stress disorder in young people with intellectual disability.

BACKGROUND: Post-traumatic stress disorder (PTSD) is common and treatable. There is extensive research on people of average intelligence yet little on individuals with developmental disabilities. METHODS: We report two people with intellectual disability (ID) who experienced PTSD. The relevance of their developmental difficulties, social and communication profiles, attentional skills, and causes of these, to their presentations is discussed. RESULTS: Both individuals have fragile X syndrome and severe ID. One has Diagnostic and Statistical Manual - 4th Edition (DSM-IV) autistic disorder; the other DSM-IV attention deficit-hyperactivity disorder. They experienced developmental and psychological regressions, new challenging behaviours and exacerbations of existing ones coincident with emotional trauma. PTSD symptoms and phenomena were identifiable despite intellectual and communicatory impairments. CONCLUSION: Presentation of PTSD is influenced by degree and cause of ID, social circumstances, social and communicatory skills, nature and timing of traumatic experience and subsequent management. The paucity of literature suggests it is missed frequently in individuals with ID who risk having problems misattributed to other causes with potential for inappropriate interventions.

Memories of Vietnam: post-traumatic stress disorders in Australian veterans.

We compared a random sample of Australian Vietnam veteran inpatients suffering from Post Traumatic Stress Disorder (PTSD) (N = 13) with veteran inpatients with other neurotic diagnoses. Those with PTSD had experienced substantially higher levels of combat stress, were more likely to have manifested conduct disorder in childhood, and had poorer work adjustment. Only three had been diagnosed as having traumatic or war neuroses by their original treating psychiatrist in the Veterans Affairs Department. Post traumatic stress disorder (or war neurosis) has possibly been under-diagnosed by treating psychiatrists in the Veterans Affairs Department, especially in the pre-DSM-III era.

Post-traumatic stress disorder in a group of Australian general practices.

BACKGROUND: Some authorities regard post-traumatic stress disorder (PTSD) as a well characterised condition that is under diagnosed in general practice. We aimed to explore its prevalence in Australian general practice. METHOD: 'Medic-GP' contains the records of 58,941 patients over a period of six years. We searched the database for PTSD and synonyms in individual records, looking for diagnostic criteria and comorbidities. RESULTS: Post-traumatic stress disorder was diagnosed in 337 patients, an annual incidence of 88/100,000 patients over a 6.5 year period. Specialists diagnosed 312 (93%) after referral by general practitioners. The GPs diagnosed 25 (7%) themselves, of whom only five patients (20%) had all seven diagnostic criteria recorded, and only 16% were free of comorbidities. DISCUSSION: General practitioners diagnosed PTSD infrequently, and at levels lower than that seen in the community. The usual psychiatric criteria were seldom recorded. Comorbid conditions were common.

Traumatic stressors and post-traumatic stress disorder symptoms in headache patients.

OBJECTIVE: The aim of this study was to assess the prevalence of significant traumatic stressors and post-traumatic stress disorder (PTSD) symptoms in a headache population. BACKGROUND: Several recent publications have emphasized the relationship between life stressors and/or daily hassles and recurrent headaches. However, little is known about the prevalence and impact of major traumatic stressors in patients with recurrent headaches. METHODS: Eighty patients with either migraine or tension-type headache completed a PTSD checklist. Data were compared with those from patients with chronic masticatory muscle pain of similar intensity and duration. RESULTS: Almost 64% of the headache patients reported one or more major traumatic stressors. This percentage was not significantly different from that of the comparison group, and fell within the broad range reported for exposure to traumatic stressors in epidemiologic studies with nonpatient populations. One out of 6 patients in the total headache sample, and 1 out of 4 of those reporting a traumatic stressor, reported symptoms suggestive of current PTSD. The prevalence of current PTSD-like symptomatology reported by the headache patients was comparable to that of the comparison group of the present study, but higher than that reported for the general population in the available literature printed in English. Traumatic stressors most often reported were not related to direct physical trauma, but rather associated with loss or serious illness of a loved one. CONCLUSION: Exposure to traumatic events in patients with a primary diagnosis of recurrent headaches is similar to that reported for chronic masticatory muscle pain patients or nonpatient populations. However, symptoms consistent with a diagnosis of current PTSD appear to be more frequent in patients with recurrent headaches than reported in the scientific literature printed in English for nonpatient populations. Screening for PTSD symptomatology is recommended as part of the routine clinical evaluation of headache.

An animal model for studying therapeutic drugs against post-traumatic stress disorder.

An animal model for the evolvement of post-traumatic stress disorder (PTSD) was developed by simulating the hormonal consequences of prolonged stress via the continuous administration of corticosterone by subcutaneously implanted sustained-release pellets. Behavioral, morphological, and biochemical effects were recorded and analyzed. This model has shown cognitive deficits as well as hippocampal damage in the rat similar to those found in PTSD patients. The model was also used to test a therapeutic treatment against stress-induced brain damages. Concomitant treatment with the L-type calcium channel blocker, nimodipine, protected young rats from corticosterone-induced morphological brain changes but not cognitive impairments. The proposed animal model may be useful for testing the efficacy of various neuroprotective drugs. Development of an effective drug treatment for use after a traumatic event and through the trauma period might prevent permanent brain damage and the development of PTSD.

Combat stress reactions, post traumatic stress disorder and somatic complaints among Israeli soldiers.

This study examined the effect of combat stress on somatic health in a sample of 804 Israeli soldiers. Three groups of subjects were assessed: combatants who did not participate in the Lebanon War, combatants who fought and suffered from combat stress reactions, and combatants who participated in the Lebanon War but did not sustain psychiatric injury. One year following the war subjects were asked to report somatic complaints and were screened for post-traumatic stress disorder. Results indicated that participation in combat per se did not have pathogenic effects. However, combat stress reactions and post-traumatic stress disorder were found to be associated with somatic complaints. The practical and theoretical implications of these findings are discussed.

Epidemiology of trauma, post-traumatic stress disorder (PTSD) and co-morbid disorders in Chile.

BACKGROUND: In this study we examined the prevalence rates of post-traumatic stress disorder (PTSD), types of trauma most often associated with PTSD, the co-morbidity of PTSD with other lifetime psychiatric disorders, which disorders preceded PTSD, and gender differences in PTSD and trauma exposure in a representative sample of Chileans. METHOD: The DSM-III-R PTSD and antisocial personality disorder modules from the Diagnostic Interview Schedule (DIS) and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic Interview (CIDI) were administered to a representative sample of 2390 persons aged 15 to over 64 years in three cities in Chile. RESULTS: The lifetime prevalence of PTSD was 4.4% (2.5% for men and 6.2% for women). Among persons exposed to trauma, rape was most strongly associated with PTSD. Onset of PTSD significantly increased the risk of developing each of the 10 other tested disorders. Among those exposed to trauma, women were significantly more likely to develop PTSD, after controlling for assaultive violence. CONCLUSIONS: This study highlights the importance of investigating the prevalence of PTSD, patterns of co-morbidity of PTSD, and gender differences in PTSD in non-English-speaking countries.

Post-traumatic stress disorder in patients with coronary artery disease: a review and evaluation of the risk.

Psychosocial factors are known to impact on the prognosis of patients with coronary artery disease independently of disease severity. However, few studies have looked at whether these patients are at risk of developing post-traumatic stress disorder, and the potential implications for morbidity and mortality. Through a review of the empirical literature, the objectives were to investigate whether patients with coronary artery disease are at risk of developing this disorder, to look at relations between post-traumatic stress disorder and heart disease, and to stimulate further research. The review indicated that some patients with coronary artery disease are at risk of developing post-traumatic stress disorder, although the prevalence varied considerably. Methodological issues together with recommendations for future research are discussed. Although only some cardiac patients may develop post-traumatic stress, this disorder should not be overlooked due to its potential role in reinfarctions and mortality.

Sanctity of human life in war: ethics and post traumatic stress disorder.

This reflective paper focuses on the moral and ethical difficulties medical care providers meet in applying DSM-IV criteria of Post Traumatic Stress Disorder in therapy and in Compensation and Pension Examinations. Providers may be less interested in articulating a philosophy of life or their own ontology than about documenting care for the patient or providing effective management of symptoms of Post Traumatic Stress Disorder. The veteran comes for assessment or therapy after an embodiment of war conflicts. Examiners and therapists spend time in clinical judgments and ethical consideration. Ethical decisions involve the sanctity of human life and the distinction made between acceptable civil and war behavior. Insight into the conflicting values found in the veterans' struggle to cope with the stress of war is needed. The stress of sending young men into harm's way is an ethical issue for veterans and the society which sends them and thereby compromises the sanctity of human life. These ethical components require the doctor and the veteran to articulate their values within ontology or a personal philosophy of life. That exchange contributes to accurate assessment and adequate therapy. Not understanding the importance of personal ontologies in treatment may make the veteran's self-disclosure difficult. Self-disclosure of one's ontology is one side of coping with Post Traumatic Stress Disorder. The other side is for powerful decision-making groups to disclose to the young recruits the full and honest account of the human cost of war before sending them into harm's way.

Psychophysiologic testing for post-traumatic stress disorder: forensic psychiatric application.

The validity of the post-traumatic stress disorder (PTSD) diagnosis is limited by both the illusory objectivity of the traumatic event and the subjectivity of the ensuing syndrome. These limitations are especially problematic in the forensic setting. Psychophysiologic measurements may strengthen PTSD's forensic value by offering a more objective assessment technique for cases that find their way into the courtroom. Based upon the results of published research studies conducted in a range of military and civilian, PTSD and non-PTSD subjects, psychophysiologic data can provide evidence helping to establish or refute the presence of the DSM-III-R PTSD arousal criteria, as well as aid psychiatric experts in estimating the probability of the disorder's presence in a given claimant. Psychophysiologic testing should be viewed as one component of a multimethod forensic psychiatric evaluation for PTSD. It is likely that it will soon be offered and, given current legal standards, admitted as evidence in civil and criminal litigation.

Elevation of serum total triiodothironine and free triiodothironine in Croatian veterans with combat-related post-traumatic stress disorder.

OBJECTIVE: To asses possible differences in serum-free triiodothironine (FT3), total triiodothironine (TT3), free thyroxine, total thyroxine, and thyroid-stimulating hormone levels between male combat veterans with chronic post-traumatic stress disorder and healthy male control subjects. METHOD: Male combat veterans (N = 38; ages 23-53 years; mean +/- SD = 35.9 +/- 7.5 years) with chronic post-traumatic stress disorder (duration of illness was 2-6 years; mean +/- SD = 3.53 +/- 0.95 years) were compared with healthy male control subjects (N = 32; ages 25-50 years; mean +/- SD = 36.5 +/- 8.3 years). Serum samples were analyzed by luminoimmunochemical assays for basal levels of thyroid-stimulating hormone, total thyroxine, TT3, free thyroxine, and FT3. RESULTS: Combat veterans with chronic combat-related post-traumatic stress disorder had significantly increased values of FT3 (mean +/- SD, 5.92 +/- 1.11; t = 2.27; p < 0.02), as well as TT3 (mean +/- SD, 2.04 +/- 0.32; t = 6.26; p < 0.0001) than the control group. CONCLUSION: Elevated serum TT3 and FT3 are associated with chronic combat-related post-traumatic stress disorder.
