Recent victimization in women and men with severe mental illness: prevalence and correlates.

The problem of violence against individuals with severe mental illness (SMI) has received relatively, little notice, despite several studies suggesting an exceptionally high prevalence of victimization in this population. This paper describes the results of an investigation of the prevalence and correlates of past year physical and sexual assault among a large sample of women and men with SMI drawn from inpatient and outpatient settings across 4 states. Results confirmed preliminary findings of a high prevalence of victimization in this population (with sexual abuse more prevalent for women and physical abuse more prevalent for men), and indicated the existence of a range of correlates of recent victimization, including demographic factors and living circumstances, history of childhood abuse, and psychiatric illness severity and substance abuse. The research and clinical implications of these findings are discussed.

Prevalence of HIV, hepatitis B, and hepatitis C in people with severe mental illness.

OBJECTIVES: This study assessed seroprevalence rates of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) among individuals with severe mental illness. METHODS: Participants (n = 931) were patients undergoing inpatient or outpatient treatment in Connecticut, Maryland, New Hampshire, or North Carolina. RESULTS: The prevalence of HIV infection in this sample (3.1%) was approximately 8 times the estimated US population rate but lower than rates reported in previous studies of people with severe mental illness. Prevalence rates of HBV (23.4%) and HCV (19.6%) were approximately 5 and 11 times the overall estimated population rates for these infections, respectively. CONCLUSIONS: Elevated rates of HIV, HBV, and HCV were found. Of particular concern are the high rates of HCV infection, which are frequently undetected. Individuals with HCV infection commonly fail to receive appropriate treatment to limit liver damage and unknowingly may be a source of infection to others.

Outcomes of single versus multiple trauma exposure in a screening sample.

Most studies ignore prior trauma exposure when evaluating outcomes of target events. This study explored symptom severity associated with different types of traumatic experiences occurring alone and with multiple exposure. The Stressful Life Events Screening Questionnaire categorized 1,909 sophomore women into groups including no trauma exposure, exposure to a serious non-Criterion A event only, exposure to several unique noninterpersonal and interpersonal events, and exposure to multiple interpersonal events. Women with noninterpersonal trauma did not differ from those without trauma on the Trauma Symptom Inventory. Only interpersonal trauma and non-Criterion A events were associated with elevated symptoms; multiple-exposure participants had significantly higher symptoms than all other groups. Complex trauma histories should be accounted for, even in studies of one target event.

Reliability of reports of violent victimization and posttraumatic stress disorder among men and women with serious mental illness.

Although violent victimization is highly prevalent among men and women with serious mental illness (SMI; e.g., schizophrenia, bipolar disorder), future research in this area may be impeded by controversy concerning the ability of individuals with SMI to report traumatic events reliably. This article presents the results of a study exploring the temporal consistency of reports of childhood sexual abuse, adult sexual abuse, and adult physical abuse, as well as current symptoms of posttraumatic stress disorder (PTSD) among 50 people with SMI. Results show that trauma history and PTSD assessments can, for the most part, yield reliable information essential to further research in this area. The study also demonstrates the importance of using a variety of statistical methods to assess the reliability of self-reports of trauma history.

HIV risk factors among people with severe mental illness in urban and rural areas.

No studies have reported HIV risk behavior in rural populations with severe mental illness. A total of 84 rural patients with severe mental illness in New Hampshire and 158 urban patients in Baltimore were interviewed about their HIV risk behavior in the past six months using the Risk Assessment Battery, a 38-item structured clinical interview. Rates of sexual and drug risk behavior among rural patients were significantly lower than among urban patients. Regression analyses showed that urban setting, younger age, never having been married, and a bisexual or gay orientation significantly predicted higher HIV risk scores. The differences in risk behaviors may reflect urban-rural differences in drug availability and sexual practices.

Court-involved battered women's responses to violence: the role of psychological, physical, and sexual abuse.

Failure to understand the importance of psychological abuse as a component of domestic violence can result in little appreciation for the complexity of victims' experience and thus a failure to provide the most effective intervention. This study examined the role of psychological abuse, physical violence, injury, and sexual abuse in predicting court-involved women's (1) prior attempts to seek help from the justice system and to leave the battering relationship, (2) use of criminal prosecution and civil protection orders, and (3) traumatic stress reactions. At the univariate level, each abuse variable was significantly associated with at least one strategic response and all traumatic responses to violence. Multivariate analyses revealed that strategic responses were largely predicted by injury and physical assault, whereas traumatic responses were mainly predicted by psychological abuse. Taken together, these findings demonstrate the important role of both physical and psychological abuse in shaping women's responses to domestic violence.

Assessing traumatic event exposure: general issues and preliminary findings for the Stressful Life Events Screening Questionnaire.

This article reviews the psychometric properties of the Stressful Life Events Screening Questionnaire (SLESQ), a recently developed trauma history screening measure, and discusses the complexities involved in assessing trauma exposure. There are relatively few general measures of exposure to a variety of types of traumatic events, and most of those that exist have not been subjected to rigorous psychometric evaluation. The SLESQ showed good test-retest reliability, with a median kappa of .73, adequate convergent validity (with a lengthier interview) with a median kappa of .64, and good discrimination between Criterion A and non-Criterion A events. The discussion addresses some of the challenges of assessing traumatic event exposure along the dimensions of defining traumatic events, assessment methodologies, reporting consistency, and incident validation.

HIV risk-behavior in poor urban women with serious mental disorders: association with childhood physical and sexual abuse.

Associations between childhood sexual and physical abuse and HIV-related risky behavior were examined among low-income, urban women with severe mental disorders. Early sexual abuse was found to be related to adult sexual and physical assault, alcohol and cocaine abuse, and prostitution; childhood physical abuse was related to adult physical assault and alcohol abuse. Findings highlight the importance of making HIV risk-reduction programs a part of integrated services that address a full range of psychosocial needs.

Modulation of N-myc expression alters the invasiveness of neuroblastoma.

N-myc oncogene expression plays a pivotal role in the biology of neuroblastoma, a common childhood tumor. High N-myc expression is associated with advanced disease stage, and in animal models, increased expression results in increased metastatic potential. In normal embryologic development, N-myc expression is associated with neuroblast migration out from the neural crest. To further define the relationship between N-myc and metastasis, an in vitro assay was adapted to measure tumor cell attachment, motility, and proteolytic ability in neuroblastoma cell lines. These parameters were examined in a non-amplified, uniformly N-myc overexpressing cell line and its anti-sense N-myc expressing clones. These lines have been characterized previously, and have a decrease in N-myc expression, growth rate, and tumorigenicity relative to the parent line and vector-only control transfectant. Decrease in N-myc expression resulted in a non-proportional increase of tumor cell attachment, and a proportional decrease in both tumor cell motility and proteolytic ability. In further experiments, assay of a N-myc-amplified overexpressing cell line with an intrinsic heterogeneous pattern of expression demonstrated that motile cells expressed higher amounts of N-myc relative to the general population. Together these relationships indicate that N-myc plays a causative role in the invasive phenotype, and suggest that metastasis may, in part, result from the disruption of a developmentally important normal process.

The relationship between violence dimensions and symptom severity among homeless, mentally ill women.

Little is known about the relationship between violence and symptomatology in the lives of homeless, mentally ill women. This study investigates the possibility that specific dimensions of violence-frequency, recentness and type-may be associated with severity of psychiatric symptomatology in this population. Results indicate that each of the abuse dimensions is associated with a broad range of psychiatric symptoms and, in combination with substance abuse, account for almost one third of the variance in overall distress. These findings suggest the possibility that intensity of exposure to violence contributes to the severity of psychiatric symptoms even in women who already suffer an overwhelming number of intrapsychic and social difficulties; and that multiply traumatized women do not become desensitized to the impact of new violence. This article discusses the clinical and policy implications of these conclusions.

Physical and sexual assault history in women with serious mental illness: prevalence, correlates, treatment, and future research directions.

An emerging body of research on the physical and sexual abuse of seriously mentally ill (SMI) women documents a high incidence and prevalence of victimization within this population. While causal links are not well understood, there is convergent evidence that victimization of SMI women is associated with increased symptom levels, HIV-related risk behaviors, and such comorbid conditions as homelessness and substance abuse. These abuse correlates may influence chronicity, service utilization patterns, and treatment alliance. This article reviews the research literature on the prevalence, symptomatic and behavioral correlates, and treatment of abuse among SMI women, particularly women with schizophrenia. Within each topic, we discuss relevant research findings, limitations of available studies, and key questions that remain unanswered. We also discuss mechanisms that may underlie the relationship between trauma and schizophrenia-spectrum disorders. We conclude by outlining directions for future research in this area.

Elevated GM2 ganglioside is associated with dendritic proliferation in normal developing neocortex.

Mature pyramidal neurons of cerebral cortex in several neuronal storage diseases elaborate ectopic dendrites. These dendrites appear specifically on pyramidal neurons containing elevated GM2 ganglioside and a variety of studies support the hypothesis that this ganglioside is responsible for inducing the new dendrite growth. To determine whether a similar association between GM2 ganglioside and dendrite growth occurs in normal neurons, we used an antibody to localize GM2 in developing cat neocortex. Our results show that GM2 ganglioside is elevated in normal cortical neurons during the period when dendritogenesis is occurring, but is greatly diminished in these cells after dendritic differentiation is complete. Elevations of GM2 occur in deep neurons earlier than in superficial ones, a sequence that corresponds closely to the inside-first, outside-last progression of cortical neuron differentiation. Ultrastructurally, GM2 immunoreactivity is found sequestered in vesicles with a distribution that coincides with sites of ganglioside synthesis and transport. The close association between elevated GM2 ganglioside and dendrite growth in cortical pyramidal neurons during normal development, coupled with a similar correlation between GM2 and ectopic dendritogenesis in neuronal storage diseases, support the view that this specific ganglioside plays a pivotal role in regulating dendritogenesis.

Contoured LCDC plating of the proximal ulna.

Comminuted fractures of the proximal ulna, particularly in combination with dislocation of the radial head, represent complex injuries which threaten both elbow and forearm motion. Thirty-seven complex proximal ulna fractures were treated with a dorsally applied, limited-contact titanium plate, contoured to fit the anatomy of the olecranon and proximal ulna. Twenty-four patients had Monteggia fracture/dislocations, and 13 had isolated but complex fractures of the proximal ulna. After an average follow up of 24 months, good or excellent functional results were achieved in 27 patients.

The relationship between victimization and cognitive schemata among episodically homeless, seriously mentally ill women.

This study explored the extent to which specific aspects of violent victimization are associated with cognitive schemata in the context of ongoing, often lifelong, trauma and negative life events. Specifically, we examined the relationships between cognitive schemata (safety, self- and other esteem, intimacy, and trust) and three dimensions of physical and sexual assault histories (recentness, frequency, and variety) among 91 predominantly African American, episodically homeless, seriously mentally ill women. Findings indicated that even in the context of pervasive violence, more frequent, recent, and varied abuse was associated with more negative cognitive schemata. We discuss these findings in the context of research and practice with disenfranchised populations at high risk for violent victimization.

Dorsal endodermal cyst of the upper cervical spine.

This report describes a case of a rare, dorsally placed enterogenous cyst at the craniocervical junction. The patient had preoperative magnetic resonance imaging studies, followed by microsurgical removal of the cyst. The patient made an uneventful recovery from the surgery. Pathological examination revealed an enterogenous cyst. Although enterogenous cysts are more commonly found in the lower cervical or thoracic spine, it is important to recognize that they may also be found at the craniocervical junction. In addition, cysts may occur posterior to the chord. Microsurgical removal is usually effective in the treatment of these cysts.

Acinic cell carcinoma of the lacrimal gland.

An 18-year-old woman underwent exenteration of the right orbit for tumor recurrence 3 years subsequent to external-beam irradiation for a lacrimal gland tumor diagnosed as an "adenocarcinoma." Light microscopy of the exenteration specimen revealed an acinic cell carcinoma of the lacrimal gland, with a predominant microcystic (latticelike) pattern of growth. Cytoplasmic vacuoles and the secretion within the microcysts stained positive with periodic acid-Schiff with and without alpha-amylase, alcian blue (at a pH of 2.5), mucicarmine, and colloidal iron with and without hyaluronidase. This histochemical staining for epithelial mucins supports the theory that the lacrimal gland, although serous in type, may also function as a modified mucus gland. There was cytoplasmic immunopositivity for keratin (CAM 5.2, KAE 1-3); immunostaining for vasoactive intestinal polypeptide was negative. Electron microscopy disclosed undifferentiated features of intercalated duct cells. We speculate that the lack of immunoreactivity for vasoactive intestinal polypeptide may be correlated with the predominantly undifferentiated intercalated duct cell features observed ultrastructurally.

Episodically homeless women with serious mental illness: prevalence of physical and sexual assault.

Three aspects of physical and sexual assault in the histories of 99 episodically homeless, seriously mentally ill women were assessed: lifetime prevalence; severity, co-occurrence, and recency; and associations between levels of this victimization and specific characteristics of the women. Results indicate that the life-time risk for violent victimization was so high (97%) as to amount to normative experiences for this population.

Posttraumatic stress disorder among battered women: analysis of legal implications.

The diagnosis of posttraumatic stress disorder (PTSD) has recently been applied to the psychological experiences of victims of intimate violence, including physical and sexual assault. The use of trauma theory to explain battered women's responses to violence has laid a foundation for expert testimony on PTSD, where relevant, within more general testimony concerning partner violence. This article discusses the relevance of the PTSD diagnosis within the legal context for explaining battered women's responses to violence.
