Dissociated or fabricated? Psychiatric aspects of repressed memory in criminal and civil cases.

During the last decade, clinicians, courts, and researchers have been faced with exceedingly difficult questions involving the crossroads where memory, traumatic memory, dissociation, repression, childhood sexual abuse, and suggestion all meet. In one criminal case, repressed memories served as the basis for a conviction of murder. In approximately 50 civil cases, courts have ruled on the issue of whether repressed memory for childhood sexual abuse may form the basis of a suit against the alleged perpetrators. Rulings that have upheld such use underscore the importance of the reliability of memory retrieval techniques. Hypnosis and other methodologies employed in psychotherapy may be beneficial in working through memories of trauma, but they may also distort memories or alter a subject's evaluation of their veracity. Because of the reconstructive nature of memory, caution must be taken to treat each case on its own merits and avoid global statements essentially proclaiming either that repressed memory is always right or that it is always wrong.

Predictors of posttraumatic stress symptoms among survivors of the Oakland/Berkeley, Calif., firestorm.

OBJECTIVE: The purpose of this study was to examine factors predicting the development of posttraumatic stress symptoms after a traumatic event, the 1991 Oakland/Berkeley firestorm. The major predictive factors of interest were dissociative, anxiety, and loss of personal autonomy symptoms reported in the immediate aftermath of the fire; contact with the fire; and life stressors before and after the fire. METHOD: Subjects were recruited from several sources so that they would vary in their extent of contact with the fire. Of 187 participants who completed self-report measures about their experiences in the aftermath of the firestorm, 154 completed a follow-up assessment. Of these 154 subjects, 97% completed the follow-up questionnaires 7-9 months after the fire. The questionnaires included measures of posttraumatic stress and life events since the fire. RESULTS: Dissociative and loss of personal autonomy symptoms experienced in the fire's immediate aftermath, as well as stressful life experiences occurring later, significantly predicted posttraumatic stress symptoms measured 7-9 months after the firestorm by a civilian version of the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder and the Impact of Event Scale. Dissociative symptoms more strongly predicted posttraumatic symptoms than did anxiety and loss of personal autonomy symptoms. Intrusive thinking differs from other kinds of posttraumatic symptoms in being related directly to the trauma and previous stressful life events. CONCLUSIONS: These findings suggest that dissociative symptoms experienced in the immediate aftermath of a traumatic experience and subsequent stressful experiences are indicative of risk for the later development of posttraumatic stress symptoms. Such measures may be useful as screening procedures for identifying those most likely to need clinical care to help them work through their reactions to the traumatic event and to subsequent stressful experiences.

Dissociative symptoms in media eyewitnesses of an execution.

OBJECTIVE: The first execution in California since 1976 took place recently in the San Quentin Prison gas chamber. Eighteen journalists were invited as media eyewitnesses. The authors postulated that witnessing this execution was psychologically traumatic and that dissociative and anxiety symptoms would be experienced by the journalists. METHOD: To investigate the prevalence and specific nature of these symptoms, questionnaires were sent to all the journalists about a month after the execution. The questionnaire contained 17 items assessing dissociative symptoms from the authors' questionnaire of 35 highly intercorrelated acute stress items. Fifteen of 18 of the witnesses returned the questionnaire. Items were endorsed on a scale of 0 ("have not experienced") to 5 ("very often experienced") and analyzed as being dichotomously present or absent. The mean age of the respondents was 37.6 (SD = 8.6) and mean years as a journalist were 15.2 (SD = 9.0). Nine subjects were men and six were women. RESULTS: Journalists witnessing the execution endorsed an average of 5.0 dissociative items, ranging from "I saw, heard, or felt things that were not really there" (endorsed by no one) to "I felt estranged or detached from other people" (endorsed by 60%). This prevalence of reported dissociative symptoms is comparable to that seen among persons who endured the recent Oakland/Berkeley, Calif., firestorm. CONCLUSIONS: The experience of being an eyewitness to an execution was associated with the development of dissociative symptoms in several journalists.

Hypnotic assessment and treatment of trauma-induced psychoses: the early psychotherapy of H. Breukink and modern views.

The role of hypnotizability assessment in the differential diagnosis of psychotic patients is still unresolved. In this article, the pioneering work of Dutch psychiatrist H. Breukink (1860-1928) during the 1920s is used as early evidence that hypnotic capacity is clinically helpful in differentiating highly hypnotizable psychotic patients with dissociative symptomatology from schizophrenics. Furthermore, there is a long tradition of employing hypnotic capacity in the treatment of these dissociative psychoses. The ways in which Breukink used hypnosis for diagnostic, prognostic, and treatment purposes are summarized and discussed in light of both old and current views. He felt that hysterical psychosis was trauma-induced, certainly curable, and that psychotherapy using hypnosis was the treatment of choice. Hypnosis was used for symptom-oriented therapy, as a comfortable and supportive mental state, and for the uncovering and integrating of traumatic memories. For the latter purpose, Breukink emphasized a calm mental state, both in hypnosis and in the waking state, thereby discouraging emotional expression, which he considered dangerous in psychotic patients. In the discussion, special attention is paid to the role and dangers of the expression of trauma-related emotions.

Dissociative reactions to the San Francisco Bay Area earthquake of 1989.

OBJECTIVE: This study systematically evaluated the psychological reactions of a nonclinical population to the October 1989 earthquake in the San Francisco Bay Area. METHOD: A representative group of about 100 graduate students from two different institutions in the Bay Area volunteered to participate in the study. Within 1 week of the earthquake, the authors administered a checklist of anxiety and dissociative symptoms to the subjects, and 4 months later they conducted a follow-up study with the same checklist. RESULTS: The participants reported significantly greater numbers and frequency of dissociative symptoms, including derealization and depersonalization, distortions of time, and alterations in cognition, memory and somatic sensations, during or shortly after the earthquake than after 4 months. To a lesser degree they also reported significantly more nonsomatic anxiety symptoms and Schneider's first-rank symptoms at the earlier testing time. CONCLUSIONS: These results suggest that among nonclinical populations, extreme distress may significantly increase the prevalence and severity of transient dissociative phenomena and anxiety. They provide further evidence of the role that dissociation plays in the response to trauma and are of considerable clinical and theoretical importance in view of the lifetime prevalence of traumatic experiences in the general population.

Predictors of smoking abstinence following a single-session restructuring intervention with self-hypnosis.

OBJECTIVE: This study examined the relation of smoking and medical history, social support, and hypnotizability to outcome of a smoking cessation program. METHOD: A consecutive series of 226 smokers referred for the smoking cessation program were treated with a single-session habit restructuring intervention involving self-hypnosis. They were then followed up for 2 years. Total abstinence from smoking after the intervention was the criterion for successful outcome. RESULTS: Fifty-two percent of the study group achieved complete smoking abstinence 1 week after the intervention; 23% maintained their abstinence for 2 years. Hypnotizability and having been previously able to quit smoking for at least a month significantly predicted the initiation of abstinence. Hypnotizability and living with a significant other person predicted 2-year maintenance of treatment response. CONCLUSIONS: These results, while modest, are superior to those of spontaneous efforts to stop smoking. Furthermore, they suggest that it is possible to predict which patients are most likely and which are least likely to respond to such brief smoking cessation interventions.

Psychosocial outcomes of cancer: a comparative analysis of Hodgkin's disease and testicular cancer.

PURPOSE: The psychosocial outcomes of testicular cancer and Hodgkin's disease were compared to test our hypotheses that more specific dysfunction and less hiding of symptoms would be found in the former group, as cancer visibly affects a sexual organ. Since those with Hodgkin's disease could more easily deny the disease, poorer psychosocial adjustment was predicted. PATIENTS AND METHODS: The sample consists of 85 men with Hodgkin's disease and 88 men with testicular cancer (seminomatous, n = 39; or nonseminomatous, n = 49). They were interviewed once, at least 1 year following the end of treatment. Measures of sociodemographic characteristics, physical functioning, psychologic distress, and social outcomes were collected. Treatment data were collected from medical records. RESULTS: Men with testicular cancer report more focused symptoms: less sexual enjoyment and poor health habits. Men with Hodgkin's disease report more generalized symptoms: fatigue, energy loss, and work impairment. Multivariate analysis indicates that most of these differences are site-related; independent effects of treatment on outcomes were found for more generalized symptoms. Contrary to expectations, both groups reported similar levels of infertility and erectile dysfunction. CONCLUSION: The response to testicular cancer is site-specific, while the response to Hodgkin's disease is related to both site and treatment (stage-related).

[Trials in ab-interno sclerostomy with a pulsed dye laser using a scleral dye: reactive black 5].

Several reports have described the successful performance of ab interno sclerostomies using a pulsed dye laser (666 nm) a goniolens and methylene blue as a scleral dye. However, the laser energy was found to have a bleaching effect on the methylene blue; therefore, methylene blue was replaced by reactive black-5 (RB-5), which seemed to be a more stable dye. To assess laser parameters using RB-5 we compared the number of pulses needed to perforate excised human sclera at different pulse durations (4-8 microseconds), energy levels (50, 100, 130-150, 200, 300 mJ) and delivery angles (20 degrees, 30 degrees, 45 degrees, 90 degrees). Fewer pulses were needed at a shorter pulse duration and higher energy levels. Above 200 mJ, 8 pulses for perforation could not be reduced; however, the width of the fistula increased. With a decrease in the delivery angle, the number of pulses for perforation increased non-proportionally above the calculated increase of the length of the fistula. At an angle of 20 degrees no perforation could be achieved even if 200 pulses of the maximal energy of 200 mJ were applied. This indicates that eyes with flat anterior chambers cannot be successfully treated.

Trauma and dissociation.

The stress associated with experiencing or witnessing physical trauma can cause abrupt and marked alterations in mental state, including anxiety and transient dissociative symptoms. Intense manifestations of this pattern of response to trauma are described in a new diagnostic category proposed for DSM-IV: acute stress disorder. Severe dissociative symptoms may predict subsequent posttraumatic stress disorder. Persons who experience a series of traumatic events may be especially vulnerable to a variety of dissociative states, including amnesia, fugue, depersonalization, and multiple personality disorder. Treatment for these symptoms emphasizes strengthening supportive interpersonal relationships and developing insight that reduces psychological pain by integrating the trauma into a meaningful, less self-blaming perspective.

Hypnosis and related techniques in pain management.

Hypnosis has been used successfully in treating cancer patients at all stages of disease and for degrees of pain. The experience of pain is influenced not only by physiological factors stemming from disease progression and oncological treatment, but also from psychosocial factors including social support and mood. Each of these influences must be considered in the successful treatment of pain. The successful use of hypnosis also depends upon the hypnotizability of patients, their particular cognitive style, their specific motivation, and level of cognitive functioning. While most patients can benefit from the use of hypnosis, less hypnotizable patients or patients with low cognitive functioning need to receive special consideration. The exercises described in this chapter can be successfully used in groups, individual sessions, and for hospice patients confined to bed. Both self-hypnosis and therapist guided hypnosis exercises are offered.

[Glaucoma parameters of the papilla. Comparison of clinical and stereophotography methods with laser scanning tomography].

The observations recorded by laser tomographic scanner (LTS) and with clinical and stereophotographic evaluation of 40 optic discs in the same glaucomatous patients were compared. Quantitative parameters (vertical and horizontal cup-to-disc ratio) and qualitative parameters (nasal excavation, notch, pseudo-pit, overpass, bayonetting) were evaluated. The correlation coefficients for the quantitative parameter ranged from 0.59 to 0.73. The definition of excavation used meant that the values found with the LTS were consistently higher. The qualitative parameter did not differ significantly with the method. Therefore, the LTS can be considered equivalent to the standard methods.
