The present study examines the relationship between suicidal behaviors and histories of abuse in psychiatric outpatients. Two hundred fifty-one psychiatric outpatients were evaluated for history of abuse, suicidal behavior, demographics, and clinical characteristics using self-report instruments and a face-to-face interview. Logistic regression analysis indicated that physical abuse (battering) in adulthood and histories of a combination of childhood and adulthood abuse were significant predictors of past suicide attempts and current suicidal ideation. Victims of abuse were more likely than nonvictim controls to have been suicidal at a younger age and to have made multiple suicide attempts. Among patients with a history of abuse, suicide attempters could be distinguished from nonattempters on the basis of higher levels of dissociation, depression, and somatization. Abusive experiences in adulthood appear to play an important role in suicidal behavior among psychiatric outpatients. High levels of specific symptoms (i.e., depression, somatization, and dissociation) among patients with a history of abuse can help to identify outpatients at risk for suicidal behavior.

Childhood abuse, adult assault, and dissociation.

Recent studies have suggested an association between childhood physical and sexual abuse and adult dissociative experiences. The purpose of this study was to determine the relationship of both childhood and adult-onset abuse and their characteristics for adult dissociative symptoms. One hundred forty-four psychiatric outpatients completed self-report questionnaires on measures of dissociation (Dissociative Experience Scale [DES]) and histories of both past and current sexual and physical abuse (Traumatic Events Questionnaire [TEQ]). Of 114 subjects (30 men and 84 women) who completed both forms, 35% and 43% reported childhood physical and sexual abuse, respectively. Dissociative symptoms were significantly related to ethnicity and multiple episodes or combined types of abuse in childhood and adulthood. In terms of the characteristics of childhood abuse, numerous episodes of physical abuse (P = .01) and father-perpetrated sexual abuse (P = .02) were significantly related to the degree of dissociation. These findings emphasize the role of repeated childhood trauma and the combination of both childhood and adult traumatic experiences in the development of dissociative phenomena.

Dissociative symptomatology and aggressive behavior.

The present study examined the relationship between dissociative symptomatology and a range of aggressive behavior in a general psychiatric outpatient population. Of the total sample (n = 122), 29% scored above 25 on the Dissociative Experiences Scale (DES). Patients with high DES scores (> 25) were significantly more likely than patients with lower DES scores (< 25) to report a history of childhood sexual abuse, to have attempted suicide, and to report more assaultive behavior, irritability, and negativism. There were no differences between the patients with high versus low DES scores on homicidal behavior. To better manage and treat outpatients with dissociative symptomatology, it is important to clarify the association between outwardly aggressive behavior and dissociative experiences.

Semiconductor probe measurements in beagle pups during deciduous tooth development.

Bone-seeking radiopharmaceuticals were used together with clinical and radiographic procedures to study tooth development in dogs. Similarities in the pattern and time course of radiopharmaceutical uptake in jaw areas studied suggest that changes in alveolar bone metabolism are not closely related to eruption times of individual teeth.
