The psychological symptoms of conjugal bereavement in elderly men over the first 13 months.

OBJECTIVE: The purpose of this study was to investigate the psychological symptoms experienced by recently widowed older men. It was hypothesized that conjugal bereavement in this group would be characterized by a mixture of depression, anxiety and loneliness. DESIGN: Double cohort study. SETTING: Suburban community population of Brisbane, Australia. PARTICIPANTS: Consecutive widowers (65+ years; N = 57) identified from official death records. Married men (65+ years; N = 57) identified from the electoral roll. Widowers interviewed at 6 weeks, 6 months and 13 months post-bereavement. Married men interviewed at similar intervals. MEASURES: Bereavement Phenomenology Questionnaire (BPQ), a 22-item self-report measure employing a four-point response scale to rate the frequency of phenomena over the previous fortnight. Zung Self-rating Depression Scale (SDS). State component of the Spielberger State/Trait Anxiety Inventory (STAI). Revised UCLA Loneliness Scale (ULS). 28-item General Health Questionnaire (GHQ). RESULTS: Widowers reported more state anxiety and general psychological distress, but not more depression or loneliness, than matched married men over the first 13 months post-bereavement. Widowers also reported more sleep disturbance and thoughts of death and suicide than married men. Level of state anxiety was strongly correlated with intensity of grief, but not with age, income, education, occupational prestige, cognitive function, duration of wife's final illness or expectedness of wife's death. CONCLUSIONS: The main hypothesis was not supported, as anxiety symptoms were the predominant clinical feature of recent conjugal bereavement among older men. The nature of these anxiety symptoms requires further investigation in recently widowed older persons.

Impact of an education program about domestic violence on nurses and doctors in an Australian emergency department.

OBJECTIVE: To increase the knowledge of nurses and doctors in an emergency department about the topic of domestic violence; to change any negative practices and attitudes toward victims; to increase knowledge of the referral processes for psychosocial aspects of domestic violence; and to increase knowledge of community resources for domestic violence victims. METHODS: Identical knowledge, attitude, and practice surveys were conducted with nurses and doctors in an emergency department before and after an educational intervention program about domestic violence. A matched-pair analysis of those respondents who answered both pretest and posttest surveys was conducted to measure the impact of the program on nurses and doctors. RESULTS: Nurses and doctors had a reasonable knowledge of the topic of domestic violence before the education program (correct answers: nurses, 61.6%; doctors, 63.4%). However, the program had a positive impact on their knowledge (correct answers posttest: nurses, 71.5%; doctors, 72.4%), with more significant changes for nurses than for doctors. The program affected both nurses' and doctors' attitudes (of 10 positive attitudinal statements: pretest, 7.9; posttest, 8.6). On both the pretest and posttest, nurses and doctors did not subscribe to a number of the myths about domestic violence that have been described in the domestic violence literature. These findings should be treated with caution because of the low response rates to the surveys from doctors (28.0%, n = 20) and nurses (53.0%, n = 48). DISCUSSION: Further research is needed into the beliefs and practices of nurses and doctors about domestic violence. The impact of this education program highlights the necessity for introducing training programs for health professionals on domestic violence problems.

Domestic violence in the Emergency Department: I. Two case-control studies of victims.

The object of this study was to compare the diagnoses and characteristics of self-reported domestic violence victims with a random sample of nonvictim controls who were selected from attendees at the Emergency Department (ED) of a major public hospital in Australia. Comparisons were made at index presentation and for the 5 years prior to index presentation. Subjects were drawn from two screening studies carried out 1 year apart which were conducted to assess the prevalence of domestic violence among attendees at the ED. From these groups, the medical records of all individuals who had disclosed domestic violence were examined and compared with the medical records of a random sample of nondisclosers, matched for age (+/- 10 years), sex, and type of entry into the ED (acute vs nonacute). The two case-control studies, conducted 12 months apart, showed that there were statistically significant differences between the diagnoses and characteristics of victims and nonvictims. Victims made more visits to the ED and Outpatients' Department than nonvictims; victims had more psychiatric index presentations; more victims had evidence of treatment of psychiatric conditions, both as inpatients and outpatients, in the previous 5 years than nonvictims; victims had greater rates of attempted suicide and alcohol problems than nonvictims at index presentation and for the previous 5 years. The findings indicate the need for the prevention and treatment of psychiatric conditions of domestic violence victims, including drug and alcohol problems and suicidal ideation. The findings form the basis of hypotheses for further studies to investigate the association between domestic violence and psychiatric illness.

Domestic violence in the Emergency Department: 2. Detection by doctors and nurses.

This study was conducted in 1991 and 1992 to determine the detection rates of domestic violence victims by doctors and nurses at the Emergency Department (ED) of Royal Brisbane Hospital, a major public hospital in Australia. The objective was to determine the outcome of an education program about domestic violence conducted in 1991 for doctors and nurses in the ED. As part of two case-control studies, the self-reports of those who disclosed domestic violence on a screening questionnaire were compared with the recording of domestic violence on each individual medical record. Subjects were drawn from two screening studies carried out 1 year apart which were conducted to assess the prevalence of domestic violence among attendees at the ED. An education program about domestic violence was conducted for doctors and nurses in the ED between the two screening studies. The examination of the medical records showed that detection rates of victims of domestic violence were unchanged between the two case-control studies. Both studies found that 50.0% of those who reported the experience of domestic violence within the 24 hours prior to index presentation, on the screening questionnaire in the prevalence studies, were recorded as such in their medical records. The low detection rates indicate the requirement for doctors and nurses to receive appropriate training to identify and record the psychosocial aspects of domestic violence victims. As well as training, referral systems need to be set in place to address the psychosocial aspects of domestic violence victims.

Measuring core bereavement phenomena.

As part of a longitudinal study of bereavement phenomena in three groups, bereaved spouses, bereaved adult children and bereaved parents, scale development was carried out using a pool of bereavement phenomenology questions administered prospectively. The items were derived from the literature, in particular studies dealing with the measurement of grief/bereavement, as well as from clinical experience. Factor analysis of theoretically grouped items produced seven subscales, three of which tapped frequently experienced phenomena in the bereaved. These three subscales formed the basis of a single measure, labelled the Core Bereavement Items (CBI), which demonstrated high reliability and sound face and discriminant validity. Preliminary analysis suggested that the CBI will prove to be a reliable and valid instrument with respect to the measure of core bereavement phenomena in commonly bereaved groups in Western society.

Psychological distress and bereavement.

Some 115 bereaved subjects (43 spouses, 39 adult children, and 33 parents) were followed-up prospectively over 12 months following the acute bereavement period. They completed the Zung Depression Scale, Spielberger's State and Trait Anxiety Measure, the GHQ-28, and Eysenck's Personality Inventory at four time points. With the exception of EPI-Extroversion, there was a significant decrease in all scores over the period encompassing the study. There were no differences between the three groups on any of the psychological variables measured. Scores on the Zung Depression Scale, state and trait anxiety, and neuroticism correlated significantly with a measure of core bereavement phenomenology, the Core Bereavement Items, at each time point for each group.

Prevalence study of domestic violence victims in an emergency department.

STUDY OBJECTIVE: In 1992, a study of the prevalence and predictors of domestic violence victims among individuals who presented to a major public hospital emergency department was conducted to replicate a study conducted by the authors in the same setting 12 months previously. The second study aimed to investigate more accurately the presentation of current victims of domestic violence to the ED. METHODS: In a retrospective, cross-sectional study, a screening questionnaire was administered to participants to establish the prevalence of a history and current presentation of domestic violence problems among patients who presented to the ED of a major public hospital. The study group comprised a representative sample of 670 male and 553 female adults (older than 16 years) who presented to all sections of a public hospital ED during 53 randomly selected 8-hour nursing shifts over an 8-week period in 1992. RESULTS: The results of the second prevalence study confirmed those of the first study. Of the 1,223 respondents in the study, 15.5% disclosed a history of adult domestic violence (8.5% of men, 23.9% of women). Women were at greater risk than men for abuse as adults (raw relative risk [RR], 3.27; 95% confidence interval [CI], 2.23 to 4.79; RR adjusted for age, history of child abuse, and country of birth, 4.13; CI, 2.86 to 5.95). Women were at greater risk than men for being doubly abused (as a child and as an adult)(raw RR, 2.17; CI, 1.33 to 3.53). The second prevalence study confirmed what had been indicated in the first study: that 2.0% of women who presented to the ED (11.6% of all women with a history of adult domestic violence) were current victims of domestic violence and that these women presented mainly between the hours of 5 pm and 8 am, when no social work services were available for referral of victims. CONCLUSION: These Australian studies support the findings of prevalence studies of domestic violence victims in ED in the United States. The prevalence and risk factors indicate the need for training of physicians and nurses in the ED about domestic violence and for provision of appropriate backup referral services such as after-hours social work services.

Large-cell variants of mantle cell lymphoma: cytologic characteristics and p53 anomalies may predict poor outcome.

Large-cell variants are uncommon in mantle cell lymphoma (MCL). Here we describe the pathologic and clinical findings in five patients with large-cell lymphoma related to MCL (L-MCL), and compare them to a group of classic small-cell MCL (s-MCL) cases. Histologically, the MC origin of the large cells was evinced by their association with a small mantle cell component in the same tissue, or their distribution in a classic mantle zone pattern, or their development in a patient with previous s-MCL. The large cells were either pleomorphic mantle cells (case 1) or transformed blast-like cells (case 2-5). The median nuclear diameter, median nuclear area and proliferation index of L-MCLs and s-MCLs, were statistically different. Immunophenotypic characterization of four specimens of L-MCL and 10 of s-MCLs with a large panel of antibodies showed the classic findings of MCL, i.e. the IgM+ D+/-, CD5+, CD10-, CD23- phenotype in all cases except two (one CD5- and one CD23+), and the association with a loose follicular dendritic cell network. Two of four L-MCLs and 5/10 s-MCLs demonstrated rearrangements of the bcl-1 gene by Southern blot or by polymerase chain reaction (PCR); 2/4 L-MCLs and 1/9 s-MCLs had p53 mutations on single-strand conformation polymorphism analysis; none of the 14 specimens showed rearrangement of bcl-2 by PCR or bcl-6 and c-myc by Southern blot. All patients with 'transformed' histology (versus 37% of all others) died of lymphoma; their survival (15-18 months; median 17) was much shorter than that of all the others (28-117+ months; median 43) (P=0.0035). All three patients with p53 anomalies, two of whom had tumours with transformed histology, died of their disease in a short time (15, 18 and 28 months). In contrast, the presence of bcl-1 rearrangements did not have prognostic implications. This study documents the existence of large-cell variants of MCL and the poor prognosis associated with the 'transformed' cytologic type and/or p53 abnormalities.

Lesion location and poststroke depression.

This study examined whether stroke lesions involving left hemisphere prefrontal or basal ganglia structures are associated with poststroke depression. A consecutive series of first-ever stroke patients with single small lesions on CT scan were examined for the presence and severity of poststroke depressive disorder. Lesions involving left prefrontal or basal ganglia structures were compared with other left hemisphere lesions and all right hemisphere lesions. Forty-one patients were examined. Patients with lesions involving left hemisphere prefrontal or basal ganglia structures had a higher frequency of depressive disorder (9/12; 75%) than other left hemisphere lesions (1/12; 8%) or those with right hemisphere lesions (5/17; 29%), P = 0.002. These findings suggest that damage to neural pathways within left hemisphere prefrontal or basal ganglia structures is associated with depressed mood following stroke.

The bereavement response: a cluster analysis.

BACKGROUND: Literature and clinical experience suggest that some people experience atypical, complicated or pathological bereavement reactions in response to a major loss. METHOD: Three groups of community-based bereaved subjects--spouses (n = 44), adult children (n = 40), and parents (n = 36)--were followed up four times in the 13 months after a loss. A 17-item scale of core bereavement times was developed and used to investigate the intensity of the bereavement response over time. RESULTS: Cluster analysis revealed a pattern of bereavement-related symptoms approximating a syndrome of chronic grief in 11 (9.2%) of the 120 subjects. None of the respondents displayed a pattern consistent with delayed or absent grief. CONCLUSIONS: In a non-clinical community sample of bereaved people, delayed or absent grief is infrequently seen, unlike chronic grief, which is demonstrated in a minority.

A comparison of the psychosocial aspects of AIDS and cancer-related bereavement.

OBJECTIVE: This study compares the psychological symptoms and bereavement distress of individuals bereaved by AIDS with a group bereaved by a cancer death, and addresses the question of whether an AIDS death is associated with a higher rate of adverse psychosocial factors that may increase risk of psychological morbidity in the bereaved individuals. METHOD: AIDS (n = 28) and cancer (n = 30) bereaved individuals (all within 3 months of the bereavement) completed measures of psychological morbidity and measures addressing a range of other adverse factors, e.g., number of losses, levels of social support and stigma. RESULTS: The cancer and AIDS bereaved were essentially similar on all psychological symptom measures. The AIDS group reported lower levels of social support in response to the bereavement than cancer bereaved individuals; a greater number of bereavements, were more likely to conceal the cause of death from significant others including their own family and perceived, in some instances, a greater level of rejection from others. The AIDS group reported higher levels of social support from friends than from family. CONCLUSIONS: At three months following bereavement, AIDS and cancer bereaved were similar in levels of distress. While this may change with the progress of grief over time, it suggests essentially similar early bereavement responses. Those bereaved by AIDS reported a range of other adverse factors such as a greater number of losses, lower social support, stigma, and less open disclosure of the cause of death.

Psychological responses to malignant melanoma. An investigation of traumatic stress reactions to life-threatening illness.

A cross-sectional study of 95 individuals with malignant melanoma was conducted to investigate posttraumatic stress responses to a diagnosis of melanoma and to validate the use of the Impact of Event Scale (IES) as a measure of the response to the trauma of life-threatening disease. The diagnosis and progression of malignant disease are likely to present a range of acute and chronic trauma to the individual and the individual's family. The findings suggest that the IES is a reliable and valid measure of this distress, with scores varying according to disease progression and prognostic status of nonmetastatic disease patients. This indicates the importance of clinical attention to the specific symptoms that may best reflect the traumatic impact of life-threatening illness and its progression, and the applicability of posttraumatic stress syndromes in understanding the psychological distress of this clinical population.

Rearrangement and expression of MDM2 oncogene in chronic lymphocytic leukemia.

Since trisomy 12 is the most common chromosome abnormality found in CLL and MDM2 has been mapped to this chromosome, we examined the possible association of MDM2 in the pathogenesis of CLL. A rearrangement of the MDM2 gene was observed in 4 of 11 peripheral blood mononuclear cells (PBMC) from patients with CLL by Southern blot hybridization. Expression of MDM2 was detected in all of the CLL samples examined by Northern blot. However, neither gross amplification nor overexpression of the MDM2 gene was found in CLL. The data suggest that MDM2 may play a role in the pathogenesis of CLL and may help to explain how abnormalities of chromosome 12 are related to CLL.

Coraco-clavicular joint: normal variant in humans. A radiographic demonstration in the human and non-human primate.

The coraco-clavicular joint is a true synovial joint that may become painful in some patients after trauma. Among the descriptions of this entity is the assertion that the coraco-clavicular joint is routinely seen in gorillas and gibbons. We undertook to assess the incidence of this variant among gorillas, gibbons, and other non-human primates. All available radiographs of large primates performed at the International Wildlife Conservation Park/Bronx Zoo (IWCP) over the past 10 years were reviewed by a musculoskeletal radiologist (human radiology). All radiographs were taken during the normal clinical care of the non-human primate population of the IWCP and are a part of each animal's clinical record. Eighty-one non-human primate radiographs were suitable for study as they contained the region of interest. The 81 radiographic examinations included 14 different species of non-human primates. The coraco-clavicular joint was seen in 4 out of 9 silver-leaf langur, 2 out of 8 lowland gorilla, and in 1 out of 6 white-handed gibbon. In all non-human primate cases where the coraco-clavicular joint occurred, it was bilateral. In 1 out of 8 mandrill, there were very wide distal clavicular ends that articulated both with the coracoid and with the acromion. The coraco-clavicular joint differs from an ossified coraco-clavicular ligament. The radiographic appearance is characteristic and is found in both humans and some non-human primate species. It may rarely become painful following trauma. When symptomatic in humans, resection of this anomalous articulation is curative.
