Abstract
This paper describes 10 core features of a neuropsychological assessment with the aim of helping neurologists understand the unique contribution the evaluation can make within the wider context of diagnostic methods in epilepsy. The possibilities, limitations and cautions associated with the investigation are discussed under the following headings. (1) A neuropsychological assessment is a collaborative investigation. (2) Assessment prior to treatment allows for the accurate assessment of treatment effects. (3) The nature of an underlying lesion and its neurodevelopmental context play an important role in shaping the associated neuropsychological deficit. (4) Cognitive and behavioural impairments result from the essential comorbidities of epilepsy which can be considered as much a disorder of cognition and behaviour as of seizures. (5) Patients' subjective complaints can help us understand objective cognitive impairments and their underlying neuroanatomy, resulting in improved patient care. At other times, patient complaints reflect other factors and require careful interpretation. (6) The results from a neuropsychological assessment can be used to maximize the educational and occupational potentials of people with epilepsy. (7) Not all patients are able to engage with a neuropsychological assessment. (8) There are limitations in assessments conducted in a second language with tests that have been standardized on different populations from that of the patient. (9) Adequate intervals between assessments maximize sensitivity to meaningful change. (10) Patients should be fully informed about the purpose of the assessment and have realistic expectations of the outcome prior to referral.

Abstract
BACKGROUND This review systematically examines the research literature published in the period 2002-8 on structured violence risk assessment instruments designed for use in mental health services or the criminal justice system. It adopted much broader inclusion criteria than previous reviews in the same area in order to capture and summarise data on the widest possible range of available instruments. OBJECTIVES To address two questions: (1) what study characteristics are associated with a risk assessment instrument score being significantly associated with a violent outcome? and (2) which risk assessment instruments have the highest level of predictive validity for a violent outcome? DATA SOURCES Nineteen bibliographic databases were searched from January 2002 to April 2008, including PsycINFO, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, British Nursing Index, International Bibliography of the Social Sciences, Education Resources Information Centre, The Cochrane Library and Web of Knowledge. REVIEW METHODS Inclusion criteria for studies were (1) evaluation of a structured risk tool; (2) outcome measure of interpersonal violence; (3) participants aged 17 years or over; and (4) participants with a mental disorder and/or at least one offence and/or at least one indictable offence. A series of bivariate analyses using either a chi-squared test or Spearman's rank-order correlation were conducted to explore associations between study characteristics and outcomes. Data from a subset of studies reporting area under the curve (AUC) analysis were combined to provide estimates of mean validity. RESULTS For the overall set of included studies (n = 959), over three-quarters (77%) were conducted in the USA, Canada or the UK. Two-thirds of all studies were conducted with offenders who had either no formal mental health diagnosis (43%) or forensic samples with a formal diagnosis (25%). The Psychopathy Checklist-Revised was tested in the largest number of studies (n = 192). Most studies (78%) reported a statistically significant (p < 0.05) relationship between the instrument score and a violent outcome. Prospective data collection (chi-squared = 4.4, p = 0.035), number of people recruited (U = 27.8, p = 0.012) and number of participants at end point (U = 26.9, p = 0.04) were significantly associated with predictive validity. For those instruments tested in five or more studies reporting AUC values, the General Statistical Information on Recidivism instrument had the highest mean AUC (0.73). LIMITATIONS Agreement between pairs of reviewers in the initial pilot exercises was good but less than perfect, so discrepancies may be present given the complexity and subjectivity of some aspects of violence research. Only five of the seven calendar years (2003-7) are completely covered, with partial coverage of 2002 and 2008. There is no weighting for sample or effect sizes when results from studies are aggregated. CONCLUSIONS A very large number of studies examining the relationship between a structured instrument and a violent outcome were published in this relatively short 7-year period. The general quality of the literature is weak in places (e.g. over-reliance on cross-sectional designs) and a vast range of distinct instruments have been tested to varying degrees. However, there is evidence of some convergence around a small number of high-performing instruments and identification of the components of a high-quality evaluation approach, including AUC analysis. The upper limits (AUC ≥ 0.85) of instrument-based prediction have probably been achieved and are unlikely to be exceeded using instruments alone.

Abstract
In the past decade UK government policy has been to develop alternative care for women detained in secure psychiatric hospital. This study evaluated the relative benefits of community-based step-down housing. Comparisons were made between female patients in community step-down housing and a control group in secure hospital who were on the waiting list for the houses. For each woman in the sample, a range of assessments was conducted on three separate occasions over a 12-month period. We noted a gradual improvement over time in women in both settings. However, by the final assessment psychological well-being and security needs were significantly better in the community group (P < 0.05). Although risks for violence and social functioning were also somewhat better in this group throughout the study, no statistically significant differences between the groups were found in these areas at any assessment time. This study has generated evidence in support of the further development of high-support step-down community housing for women in secure psychiatric care. This initiative may provide greater personal freedom and enhanced relational security for the women concerned while also facilitating improvements in their psychological well-being, with no increased risk to the women themselves or to the wider community.

Abstract
BACKGROUND It has been estimated that violence accounts for more than 1.6 million deaths worldwide each year and these fatal assaults represent only a fraction of all assaults that actually occur. The problem has widespread consequences for the individual and for the wider society in physical, psychological, social and economic terms. A wide range of pharmacological, psychosocial and organisational interventions have been developed with the aim of addressing the problem. This review was designed to examine the effectiveness of these interventions when they are developed in mental health and criminal justice populations. OBJECTIVE To update a previous review that examined the evidence base up to 2002 for a wide range of pharmacological, psychosocial and organisational interventions aimed at reducing violence, and to identify the key variables associated with a significant reduction in violence. DATA SOURCES Nineteen bibliographic databases were searched from January 2002 to April 2008, including PsycINFO (CSA) MEDLINE (Ovid), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), British Nursing Index/Royal College of Nursing, International Bibliography of the Social Sciences (IBSS), Education Resources Information Center (ERIC)/International ERIC, The Cochrane Library (Cochrane reviews, other reviews, clinical trials, methods studies, technology assessments, economic evaluations), Web of Science [Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI), Arts & Humanities Citation Index (A&HCI)]. REVIEW METHODS The assessment was carried out according to accepted procedures for conducting and reporting systematic reviews, including identification of studies, application of inclusion criteria, data extraction and appropriate analysis. Studies were included in meta-analyses (MAs) if they followed a randomised control trial (RCT) design and reported data that could be converted into odds ratios (ORs). For each MA, both a fixed-effects model and a random-effects model were fitted, and both Q statistic and I2 estimates of heterogeneity were performed. RESULTS A total of 198 studies were identified as meeting the inclusion criteria; of these, 51 (26%) were RCTs. Bivariate analyses exploring possible sources of variance in whether a study reported a statistically significant result or not, identified six variables with a significant association. An outcome was less likely to be positive if the primary intervention was something other than a psychological or pharmacological intervention, the study was conducted in an penal institution, the comparator was another active treatment or treatment as usual and if a between-groups design had been used. An outcome was more likely to be positive if it was conducted with people with a mental disorder. The variation attributable to these variables when added to a binary logistic regression was not large (Cox and Snell R(2) = 0.12), but not insignificant given the small number of variables included. The pooled results of all included RCTs suggested a statistically significant advantage for interventions over the various comparators [OR 0.59, 95% confidence interval (CI) 0.53 to 0.65, fixed effects; OR 0.35, 95% CI 0.26 to 0.49 random effects, 40 studies]. However, there was high heterogeneity {I(2) = 86, Q = 279 [degrees of freedom (df) = 39], p < 0.0001}, indicating the need for caution in interpreting the observed effect. Analysis by subgroups showed that most results followed a similar pattern, with statistically significant advantages of treatments over comparators being suggested in fixed- and/or random-effects models but in the context of large heterogeneity. Three exceptions were atypical antipsychotic drugs [OR 0.21, 95% CI 0.16 to 0.27, fixed effects; OR 0.24, 95% CI 0.14 to 0.43, random effects; 10 studies, I(2) = 72.2, Q = 32.4 (df = 9), p < 0.0001], psychological interventions [OR 0.63, 95% CI 0.48 to 0.83, fixed effects; OR 0.53, 95% CI 0.31 to 0.93, random effects; nine studies, I(2) = 62.1, Q = 21.1 (df = 8), p = 0.007] and cognitive behavioural therapy (CBT) as a primary intervention [OR 0.61, 95% CI 0.42 to 0.88, fixed effects; OR 0.61, 95% CI 0.37 to 0.99, random effects; seven studies, I(2) = 21.6, Q = 7.65 (df = 6), p = 0.26]. LIMITATIONS The heterogenity of the included studies inhibits both robust MA and the clear application of findings to establishing improvements in clinical practice. CONCLUSIONS Results from this review show small-to-moderate effects for CBT, for all psychological interventions combined, and larger effects for atypical antipsychotic drugs, with relatively low heterogeneity. There is also evidence that interventions targeted at mental health populations, and particularly male groups in community settings, are well supported, as they are more likely to achieve stronger effects than interventions with the other groups. Future work should focus on improving the quality of evidence available and should address the issue of heterogenity in the literature.

Bilateral capacity for speech sound processing in auditory comprehension: evidence from Wada procedures. BRAIN AND LANGUAGE 2008; 107:179-84. [PMID: 18976806 PMCID: PMC2644214 DOI: 10.1016/j.bandl.2008.09.006] [Citation(s) in RCA: 48] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2007] [Revised: 08/12/2008] [Accepted: 09/15/2008] [Indexed: 05/02/2023]
Abstract
Data from lesion studies suggest that the ability to perceive speech sounds, as measured by auditory comprehension tasks, is supported by temporal lobe systems in both the left and right hemisphere. For example, patients with left temporal lobe damage and auditory comprehension deficits (i.e., Wernicke's aphasics), nonetheless comprehend isolated words better than one would expect if their speech perception system had been largely destroyed (70-80% accuracy). Further, when comprehension fails in such patients their errors are more often semantically-based, than-phonemically based. The question addressed by the present study is whether this ability of the right hemisphere to process speech sounds is a result of plastic reorganization following chronic left hemisphere damage, or whether the ability exists in undamaged language systems. We sought to test these possibilities by studying auditory comprehension in acute left versus right hemisphere deactivation during Wada procedures. A series of 20 patients undergoing clinically indicated Wada procedures were asked to listen to an auditorily presented stimulus word, and then point to its matching picture on a card that contained the target picture, a semantic foil, a phonemic foil, and an unrelated foil. This task was performed under three conditions, baseline, during left carotid injection of sodium amytal, and during right carotid injection of sodium amytal. Overall, left hemisphere injection led to a significantly higher error rate than right hemisphere injection. However, consistent with lesion work, the majority (75%) of these errors were semantic in nature. These findings suggest that auditory comprehension deficits are predominantly semantic in nature, even following acute left hemisphere disruption. This, in turn, supports the hypothesis that the right hemisphere is capable of speech sound processing in the intact brain.

Abstract
Patients with cardiac dysfunction may be at increased risk of cardiac toxicity when undergoing hematopoietic stem cell transplantation (HSCT), which may preclude them from receiving this therapy. Cardiac dysfunction is, however, common in systemic lupus erythematosus (SLE) patients. While autologous HSCT (auto-HSCT) has been performed increasingly for SLE, its impact on cardiac function has not previously been evaluated. We, therefore, performed a retrospective analysis of SLE patients who had undergone auto-HSCT in our center to determine the prevalence of significant cardiac involvement, and the impact of transplantation on this. The records of 55 patients were reviewed, of which 13 were found to have abnormal cardiac findings on pre-transplant two-dimensional echocardiography or multi-gated acquisition scan: impaired left ventricular ejection fraction (LVEF) (n = 6), pulmonary hypertension (n = 5), mitral valve dysfunction (n = 3) and large pericardial effusion (n = 1). At a median follow-up of 24 months (8-105 months), there were no transplant-related or cardiac deaths. With transplant-induced disease remission, all patients with impaired LVEF remained stable or improved; while three with symptomatic mitral valve disease similarly improved. Elevated pulmonary pressures paralleled activity of underlying lupus. These data suggest that auto-HSCT is feasible in selected patients with lupus-related cardiac dysfunction, and with control of disease activity, may improve.

Abstract
OBJECTIVE To estimate minimally important differences (MIDs) in scores for the modified Rodnan Skin Score (mRSS) and Health Assessment Questionnaire-Disability Index (HAQ-DI) in a clinical trial on diffuse systemic sclerosis (SSc). PARTICIPANTS AND METHODS 134 people participated in a 2-year, double-blind, randomised clinical trial comparing efficacy of low-dose and high-dose D-penicillamine in diffuse SSc. At 6, 12, 18 and 24 months, the investigator was asked to rate the change in the patient's health since entering the study: markedly worsened, moderately worsened, slightly worsened, unchanged, slightly improved, moderately improved or markedly improved. Patients who were rated as slightly improved were defined as the minimally changed subgroup and compared with patients rated as moderately or markedly improved. RESULTS The MID estimates for the mRSS improvement ranged from 3.2 to 5.3 (0.40-0.66 effect size) and for the HAQ-DI from 0.10 to 0.14 (0.15-0.21 effect size). Patients who were rated to improve more than slightly were found to improve by 6.9-14.2 (0.86-1.77 effect size) on the mRSS and 0.21-0.55 (0.32-0.83 effect size) on the HAQ-DI score. CONCLUSION MID estimates are provided for improvement in the mRSS and HAQ-DI scores, which can help in interpreting clinical trials on patients with SSc and be used for sample size calculation for future clinical trials on diffuse SSc.

Protection of ischemic rat spinal cord white matter: Dual action of KB-R7943 on Na+/Ca2+ exchange and L-type Ca2+ channels. Neuropharmacology 2005; 48:566-75. [PMID: 15755484 DOI: 10.1016/j.neuropharm.2004.12.007] [Citation(s) in RCA: 50] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2004] [Revised: 12/10/2004] [Accepted: 12/15/2004] [Indexed: 10/25/2022]
Abstract
The effect of the Na+/Ca(2+)-exchange inhibitor KB-R7943 was investigated in spinal cord dorsal column ischemia in vitro. Oxygen/glucose deprivation at 37 degrees C for 1 h causes severe injury even in the absence of external Ca2+. KB-R7943 was very protective in the presence and absence of external Ca2+ implicating mechanisms in addition to extracellular Ca2+ influx through Na+/Ca(2+)-exchange, such as activation of ryanodine receptors by L-type Ca2+ channels. Indeed, blockade of L-type Ca2+ by nimodipine confers a certain degree of protection of dorsal column against ischemia; combined application of nimodipine and KB-R7943 was not additive suggesting that KB-R7943 may also act on Ca2+ channels. KB-R7943 reduced inward Ba2+ current with IC50 = 7 microM in tsA-201 cells expressing Ca(v)1.2. Moreover, nifedipine and KB-R7943 both reduced depolarization-induced [Ca2+]i increases in forebrain neurons and effects were not additive. Nimodipine or KB-R7943 also reduced ischemic axoplasmic Ca2+ increase, which persisted in 0Ca2+/EGTA perfusate in dorsal column during ischemia. While KB-R7943 cannot be considered to be a specific Na+/Ca2+ exchange inhibitor, its profile makes it a very useful neuroprotectant in dorsal columns by: reducing Ca2+ import through reverse Na+/Ca2+ exchange; reducing influx through L-type Ca2+ channels, and indirectly inhibiting Ca2+ release from the ER through activation of ryanodine receptors.

Abstract
It has been recommended that all patients attending hospital accident and emergency departments in the United Kingdom (UK) with self-harm should be offered adequate psychosocial assessment to identify those at risk of completed suicide or repeated self-harm. This paper focuses on the extent to which this recommendation has been implemented in a large district general hospital in Wales, and compares the characteristics and hospital management of patients who received no specialist assessment with those who were assessed by a psychiatric liaison nurse or a psychiatrist. Data were routinely collected as part of the hospital annual audit procedure and confirm previous findings that guidelines for the general hospital management of self-harm patients have not been well implemented. Whilst we found some evidence that certain high risk patient groups were more likely to receive specialist assessment, this was far from universal. We conclude that if there is to be a reduction in the rate of suicide in Wales and the UK as a whole, it is crucial that services for people who self-harm are more appropriately targeted on patients who are at greatest risk.

Abstract
In recent years the British government has sought to target service provision both on people with severe enduring mental illness and on those considered to be at risk of suicide. The study reported here suggests these policies may have had unforeseen repercussions on services for people who self-harm but have no identifiable mental illness. This paper compares the hospital management of self-harm patients with and without mental illness. Over the years 1996-2000, a total of 4,329 self-harm patient attendances were recorded at the accident and emergency department of a British hospital. Whilst patients in 63.7% of attendances could reasonably have been considered to have some form of mental illness, we found that in the remaining 36.3% of attendances (where patients had no indicator of mental illness) a particularly poor standard of service was given. We suggest that if government targets for a reduction in the suicide rate are to be met, it is crucial that there should be marked improvements in services for all self-harm patients presenting at accident and emergency departments. However, in improving services we must be vigilant to the danger that targeting those with a mental illness may mean we fail to provide even basic levels of care for others.

Abstract
Many commonly used measures of figural reproduction have been found to be relatively insensitive to the effects of right temporal lobe dysfunction. More positive findings are present in studies using measures of figural learning over repeated trials. This study examined the use of a commercially available measure of figural learning in a sample of epilepsy patients undergoing presurgical neuropsychological testing. The Brief Visuospatial Memory Test-Revised (BVMT-R) was administered to 47 subjects undergoing comprehensive presurgical workups with video and EEG monitoring. Groups with left (N = 25) and right (N = 22) temporal lobe seizures did not differ on BVMT-R measures of learning, delayed recall, or yes/no recognition. Approximately 29% of the sample exhibited "impaired" performance in comparison to published norms. The results of receiver operating curve analyses revealed little discrimination in performance between groups. The BVMT-R does not appear to have the sensitivity required for assessing nonverbal memory in this population.

Abstract
At Northwestern University, a phase I/II trial of hematopoietic stem cell transplant (HSCT) for systemic lupus erythematosus (SLE) has shown promising results. A phase III HSCT trial is being developed to confirm efficacy of HSCT vs continuing the currently accepted standard of care, intravenous pulse cyclophosphamide.

Abstract
Hematopoietic stem cell transplantation (HSCT) for autoimmune diseases have been, because of safety reasons, overwhelmingly autologous. Results are, in general, encouraging with improvement in quality of life, a remission of up to several years, and perhaps in some diseases improved survival. This indicates that further study of autologous HSCT especially under phase III design is warranted. However, the ultimate goal of HSCT is cure of otherwise incurable autoimmune diseases. For this reason, allogeneic HSCT in carefully selected high-risk patients with autoimmune diseases using strategies to minimize both regimen-related toxicity and graft-versus-host disease (GVHD) is ongoing at Northwestern University and will be reviewed briefly.

Abstract
The substantial morbidity and mortality associated with rheumatoid arthritis (RA), while not widely appreciated, provide adequate justification for consideration of high-dose immunoablative therapy followed by hematopoietic stem cell transplantation. While some patients with RA follow a benign course, selected subsets of patients have been identified with 5-year survival rates of 40-70%. A number of factors that can be easily determined serve as useful prognostic indicators for poor outcome. These include the presence of many involved joints (total joint count), the degree of functional disability as measured by the health assessment questionnaire and the presence of rheumatoid factor. This article summarises the present status of hematopoietic stem cell transplantation for rheumatoid arthritis and proposes future directions for research.

Abstract
Reducing social exclusion and improving mental health are key themes within the government's modernization programme. Despite this, little is known about the social exclusion experienced by people with severe and enduring mental illness living in specific communities, apart from their over-representation amongst various socially excluded groups. This paper describes a 3-year research study that focused on the impact of introducing mental health registers into general practices in an English health district. The registers were expected to facilitate improvements in linking patients with appropriate services and so improve the healthcare they received. The overall result should have been reductions in the levels of social exclusion experienced by these patients; however, findings revealed a lack of change in unmet needs and quality of life, even amongst those in contact with a community mental health nurse.

Abstract
PURPOSE To identify and define clinical and behavioral features of patients with adult-onset idiopathic generalized epilepsy (IGE). METHODS We reviewed the charts of 313 IGE patients at the NYU Comprehensive Epilepsy Center over the past 5 years to identify patients with adult onset (18 years old or older). We excluded patients with childhood or adolescent symptoms that suggested absence, myoclonic, or tonic-clonic seizures, as well as those with a history of significant head injury or other known causes of localization-related epilepsy. RESULTS Forty-two (13.4%) patients had a clear onset of IGE in adulthood; average age of onset was early 20s (mean, 23.8 years; range, 18-55 years). Twenty-one patients had adult myoclonic epilepsy (AME, 50%), and three had generalized tonic-clonic seizures on awakening (GTCS-A, 7%). More than two thirds (n=30) are well controlled with current antiepileptic drugs (AEDs), and almost 90% are currently employed (n=37). One third were diagnosed and treated for mental disorders, including depression (n=12), anxiety (n=7), obsessive-compulsive personality disorder (n=2), and postictal psychosis (n=1). CONCLUSIONS Adult-onset IGE is associated with a good prognosis. An association may exist between psychological disorders, psychotropic medication, and level of seizure control in adults with IGE.

Abstract
Patients with coincidental rheumatoid arthritis (RA) treated by allogeneic hematopoietic stem cell transplantation (HSCT) for drug induced aplastic anemia have been fortuitously cured of RA. Other than these examples with allogeneic HSCT, there is no known curative therapy for RA. Despite its potential to cure, allogeneic transplantation is not being offered to patients with RA due to transplant related mortality. Advances in HSCT conditioning regimens and better prevention of graft-versus-host disease should allow consideration of allogeneic HSCT as therapy for severe RA. We propose a new, well tolerated, nonmyeloablative allogeneic stem cell transplant regimen as treatment for RA.

Abstract
There is little information about the clinical course of patients with rheumatoid arthritis (RA) who relapse after autologous blood stem cell transplantation (ASCT). We describe 6 patients with severe RA who received ASCT in 3 US centers. Duration of followup was between 24 and 42 months posttransplant. Five patients achieved major responses but relapsed 3-22 months posttransplant. Two patients with relapse improved remarkably after restarting disease modifying antirheumatic drugs (DMARD). Two patients developed a mild RA flare at 3 and 5 months posttransplant and improved spontaneously. All 4 patients who improved after an initial disease flare remained highly functional at 14-22 months posttransplant. All patients in this study were anti-tumor necrosis factor (TNF) drug naive; all received a TNF blocker as a second line posttransplant salvage therapy, but only 3 responded. Future ASCT strategies need to focus on improving the durability of the early posttransplant responses.

Abstract
OBJECTIVES To compare the systemic sclerosis (SSc) patients entered into the d-penicillamine trial with SSc patients entered into previous controlled SSc trials. It was hypothesized that the d-penicillamine trial patients, who conformed to the American College of Rheumatology (ACR) guidelines for clinical trials in SSc were different from patients entered into previous trials. METHODS Patients entering a double-blind, randomized trial of low- vs high-dose d-penicillamine were described carefully and completely. Their characteristics were then compared with previously published data on SSc and its treatment. RESULTS One hundred and thirty-four patients had early [mean duration 9.5 (s.d. 4.2) months], diffuse [skin score 21 (8)] disease. Organ involvement in the patients was as follows: pulmonary 54%, cardiac 20%, joints 38%, muscular 20%. Thirty-three per cent had mild proteinuria and 13% were hypertensive when first seen. Compared with patients in most previous studies, these SSc patients had earlier disease and uniformly had diffuse disease. They had less muscular involvement, less dyspnoea, less abnormal pulmonary function and less cardiac and less renal involvement than patients in earlier studies. CONCLUSIONS The use of the new ACR guidelines for SSc trials may change the nature of patient populations entering future studies.

Abstract
BACKGROUND Successive governments have urged mental health service providers to target their attentions on people with severe and enduring mental illness (SEMI). However, community mental health teams (CMHTs) in general, and community mental health nurses (CMHNs) in particular, have been criticized for failing to meet this requirement. This paper reports selected findings from a wider study that assessed the impact of an initiative designed to facilitate service targeting: the establishment of registers of patients with SEMI in general practices throughout an English health district. The paper describes changes in the nature of community mental health nursing contacts with a sample of patients on these registers. METHODS Six general practices were randomly selected from the 65 practices in the district and comparisons made between patients on the six mental health registers who either had, or did not have, community mental health nursing contact. These comparisons related to the year before the establishment of the registers, the year during which they were being established and the year following this. RESULTS A total of 274 patients were included on the sample registers, with practices varying considerably in relation to proportions of mental health registered patients with community mental health nursing contact. Overall, the number of patients in contact with CMHNs was found to have decreased over time, except for those on level 2 of the Care Programme Approach. CONCLUSIONS No evidence was found to support the hypothesis that the establishment of the registers had improved CMHN targeting of patients with SEMI. However, findings were inconclusive because shortages of CMHNs and the disruption associated with widespread service reorganization meant the registers were never fully implemented in practices during the study period.

Abstract
OBJECTIVE To explore the clinical implications of a score of > or =1.0 on the Disability Index of the Health Assessment Questionnaire (HAQ DI) at the first patient visit, and to examine the implications of improvement in HAQ DI score over 2 years in a cohort of systemic sclerosis (SSc) patients with diffuse cutaneous scleroderma. METHODS SSc skin and visceral involvement was assessed in 134 SSc patients with diffuse scleroderma (mean +/- SD disease duration of 10 +/- 4 months) when they entered a multicenter drug trial and again 2 years later. Mortality and the occurrence of scleroderma renal crisis were assessed for a mean +/- SD of 4.0 +/- 1.1 years. Logistic and linear regression analyses were used to examine the relationship of the baseline HAQ DI score to morbidity, mortality, and visceral involvement, as well as the relationship of changes in the HAQ DI score to changes in physical examination, laboratory, and functional variables over 2 years. RESULTS A baseline HAQ DI score of > or =1.0 was predictive of mortality (odds ratio 3.22, 95% confidence interval 1.097-9.468) over 4 years. Multivariate linear regression demonstrated that a model which included the erythrocyte sedimentation rate at baseline (P = 0.005) and changes at 2 years in the swollen joint count (P = 0.002), total skin score (P = 0.005), and white blood cell count (P = 0.005) best explained the change in HAQ DI score over 2 years (R2 = 0.528). The HAQ DI score and total skin score at baseline were highly correlated (correlation coefficient 0.368), as were changes in the HAQ DI score and the total skin score over 2 years (correlation coefficient 0.492). Although the HAQ DI score was heavily influenced by hand dysfunction at baseline and at 2 years, improvement (reduction) in the HAQ DI score over 2 years was related to factors other than hand dysfunction. CONCLUSION A baseline HAQ DI score of > or =1.0 predicted mortality over 4 years. Improvement in the HAQ DI score in these patients with diffuse scleroderma was associated with improvement in skin thickening, hand function, oral aperture, lung function, signs of arthritis, serum creatinine level, and the investigator's global assessment of improvement. The HAQ DI is a self-administered questionnaire that SSc patients can complete easily and rapidly and that gives the practicing physician important information about prognosis, patient status, and changes in disease course over time.

Abstract
OBJECTIVE To study the clinical implications of a skin thickness score > or =20 at first visit and of softening of sclerodermatous skin in a cohort of systemic sclerosis (SSc) patients with diffuse cutaneous scleroderma. METHODS Skin and visceral involvement were assessed in 134 SSc patients with diffuse scleroderma (mean +/- SD duration of SSc 10 +/- 4 months) as they entered a multicenter drug trial and again at 2 years of followup. Advent of mortality and scleroderma renal crisis (SRC) were assessed during a followup of 4.0 +/- 1.1 years (mean +/- SD). Logistic and linear regression were used to examine the relationship of baseline skin score to morbidity, mortality, and visceral involvement and the relationship of changes in skin score to changes in physical examination, laboratory, and functional variables over 2 years. RESULTS A baseline skin score > or =20 was associated with heart involvement at baseline (odds ratio [OR] 3.10, 95% confidence interval [95% CI] 1.25-7.70) and was predictive of mortality (OR 3.59, 95% CI 1.23-10.55) and SRC (OR 10.00, 95% CI 2.21-45.91) over 4 years. Multivariate linear regression demonstrated that a model with skin score at baseline (P = 0.0078) and changes in large joint contractures (P = 0.0072), tender joint counts (P = 0.0119), handspread (P = 0.0242), and Health Assessment Questionnaire disability index (HAQ-DI) (P = 0.0244) explained the change in skin score over 2 years (R2 = 0.567). Multivariate logistic regression demonstrated that the investigator's global assessment of improvement was best explained by a model with skin score and HAQ-DI (R2 = 0.455). CONCLUSION A baseline skin score > or =20 was associated with heart involvement at baseline and predicted mortality and SRC over the subsequent 4 years. Improvement in skin score in these patients with diffuse cutaneous scleroderma was associated with improvement in hand function, inflammatory indices, joint contractures, arthritis signs, overall functional ability, and the examining investigator's global assessment of improvement.

Abstract
Damasio and colleagues (1996) have proposed that the left anterior temporal region supports knowledge pertaining to living objects, whereas more posterior temporal regions play a critical role in naming nonliving things. Accordingly, one might expect that left-sided anterior temporal lobectomy should have a more profound effect on the naming of living as opposed to nonliving things. As part of a multicenter collaborative project, seventy-nine patients (all left-hemisphere speech dominant) were tested pre- and post-left-temporal lobectomy on a task that required naming of living and nonliving items equated for name frequency, familiarity, and visual complexity. Consistent with the proposals of Damasio et al. (1996), left temporal lobectomy impaired naming ability, particularly for living things. When individual outcomes were considered, twice as many patients showed a relative decline in naming living as opposed to nonliving things.

Abstract
Community mental health nurses have been criticized for failing to prioritize work with people with a severe or enduring mental illness, many of whom have no contact with specialist mental health services and rely entirely on their general practitioner and primary care team. It is important to ensure that those in contact with specialist services actually need this level of input but, conversely, that those in contact with only primary care receive a service that is equipped to meet their needs. This study examines the differences between these two groups of patients. A sample of 253 community-based patients with a severe or enduring mental illness was divided into those with mental health service contact and those without. Differences in the demographic characteristics of the two groups were assessed and further, more detailed, comparisons were made with a sub-sample of 49 individuals randomly drawn from this larger sample. Instruments adopted for these purposes comprised the Camberwell Assessment of Need and the Life Fulfilment Scale. It was found that patients with a psychotic disorder were more likely than those with neurosis to be in contact with mental health services and patients with schizophrenia were significantly more likely to be on the active caseload of a community mental health nurse than those from all other diagnostic groups. However, patients' levels of need, unmet need and quality of life did not differ in relation to their service contact. Whilst the study provides limited evidence that community mental health nurses are targeting people with the most serious disorders, questions remain about the large proportion not receiving specialist care. Because primary care plays a significant role in the care of severely mentally ill people living in the community, the further mental health training of general practitioners and practice nurses is becoming increasingly important.

Abstract
The idea that the stars and planets may influence human health and behavior can be traced to at least Roman times, and research suggests a high proportion of health professionals continue to hold this belief. Nevertheless, evidence for the supposed influence of the moon on human behavior has proved particularly elusive, and research has tended to suffer from weaknesses in methodology and data analysis. This article reports findings drawn from a re-analysis of data from a research study into the functioning of a sample of mentally ill people living in the community. The mental health and quality of life of a sample of 100 people were assessed on four occasions during a 30-month period. Data were aggregated to represent the span of one lunar month, with scores being allocated to the relevant week of the lunar cycle during which each assessment was made. Comparison of mean values across the weeks of the lunar cycle was preformed using the ANOVA, Results showed significant change at the time of the full moon only in subjects with a diagnosis of schizophrenia (n = 56), where deterioration was observed in three areas of psychopathology and one area of quality of life. Some implications for nursing practice are discussed, and it is suggested that future research into the possibility of a lunar effect on human life should focus on the direct measurement of functioning in people with schizophrenia.

Abstract
BACKGROUND AND PURPOSE Some stroke patients and their families express reservations about participating in trials of experimental therapies for acute stroke. Among many reasons given for this is the concern that by participating, patients may be deprived of some component of routine care. We sought to determine the effect on outcome of participating in a clinical stroke trial while being treated with placebo. METHODS Prospective clinical information was collected for all patients admitted with acute ischemic stroke between July 1995 and July 1996. A subgroup of these patients was enrolled in a clinical trial of acute stroke therapy and had been randomly assigned to the placebo group. The control group was selected from concurrent stroke patients who were not enrolled in any clinical trial. The National Institutes of Health Stroke Scale (NIHSS) was performed on admission and on day 7 after admission. The Glasgow Outcome Scale (GOS) was also performed at discharge. Stroke severity was classified as "severe" if NIHSS was >/=9 or GOS >/=3. Group comparisons were performed with chi(2) tests. RESULTS One hundred twenty-six patients were evaluated. Forty-seven were placebo patients, and 79 were selected as control subjects. There were no significant differences between the groups with respect to age, sex, hematocrit, blood glucose level, history of hypertension, diabetes, smoking, or initial NIHSS. In addition, there was no difference between groups in terms of the frequency of baseline stroke subtype. Among our controls, 55 patients (70%) were on antithrombotic treatment during hospitalization, whereas none of our placebo patients were on any antithrombotic treatment. For the GOS at follow-up, a good outcome was attained by 76% of the control subjects and 72% of placebo patients (not significant). A severe NIHSS (>9) at follow-up, however, was documented in 15% of controls and 59% of placebo patients (P<0.001). There was a trend toward a higher ("worse") mean follow-up NIHSS among placebo patients (mean NIHSS, 11) versus controls (mean NIHSS, 6) (P=0.09). CONCLUSIONS Patients enrolled in the placebo arms of some acute clinical stroke trials have similar functional outcomes but more severe neurological deficits at 1 week than did a control group. These findings might be partially explained by the withholding of antithrombotic medication and the exclusion criteria inherent in most trials. Vigilance is required to ensure that all patients participating in stroke studies be guaranteed optimal known medical therapy.

Abstract
UNLABELLED Background Although aspirin (ASA) has been shown to be effective for secondary (but not primary) stroke prevention and to have some beneficial influence on outcome when taken early after stroke onset, studies regarding the impact of prior use of ASA on stroke severity are conflicting. OBJECTIVES To determine whether ASA therapy begun before stroke onset lessens the severity of stroke. METHODS Prospective clinical information was collected for all patients admitted with their first acute ischemic stroke between July 1996 and July 1998. National Institutes of Health Stroke Scale (NIHSS) scores were noted on admission and at discharge. Barthel Index (BI), Modified Rankin Scale (MRS), and Glasgow Outcome Scale (GOS) scores were also noted at discharge. Stroke severity was classified as severe if the NIHSS score was 9 or greater, BI score was 55 or less, the MRS score was 4 or greater, or the GOS score was 3 or greater. Group comparisons were performed by using the X(2) tests. RESULTS 178 patients were evaluated. Forty-two were taking ASA and 136 were not taking ASA or any other anti-thrombotic drug. There were no differences between the 2 groups in terms of age, gender, baseline hematocrit or blood glucose, history of hypertension, diabetes, atrial fibrillation, smoking, or stroke subtype. There were no significant differences between the 2 groups on any of the scales, either on admission or at discharge. CONCLUSION Our data do not suggest that ASA use before stroke onset lessens the severity of first stroke. Until this question is definitively settled, however, it would be prudent to ensure balanced distribution of recent ASA use in acute stroke treatment trials.

Abstract
OBJECTIVE To evaluate functional impairment in systemic sclerosis (SSc) patients with diffuse cutaneous scleroderma at the time of entry into a trial of a therapeutic intervention (D-penicillamine). METHODS The 20-item Disability Index of the Health Assessment Questionnaire (HAQ-DI) was administered to 134 patients as they entered a multicenter trial of high-dose versus low-dose D-penicillamine. All patients had diffuse SSc of < 18 months' duration. SSc patients who had severe organ system involvement and recent renal crisis and who were receiving prednisone > 10 mg/day were excluded from entry. Logistic regression modeling was used to examine the relationship of HAQ-DI scores to SSc skin and organ system involvement. Odds ratios (OR) and 95% confidence intervals (95% CI) were used to estimate effects. RESULTS The mean (+/-SD) HAQ-DI score at entry was 1.04 +/- 0.67. Fifty-three percent of patients had HAQ-DI scores > or = 1.0 (signifying moderate-to-severe functional impairment). Multivariate logistic regression demonstrated that impaired fist closure > or = 23 mm (OR 4.24, 95% CI 1.68-10.70), reduced handspread < or = 175 mm (OR 4.5, 95% CI 1.80-11.24), joint tenderness count > or = 1.0 (OR 2.93, 95% CI 1.16-7.40), age > or = 43 years (OR 2.44, 95% CI 1.01-5.95), platelet count > or = 330,000/mm3 (OR 2.30, 95% CI 0.96-5.57), and female sex (OR 2.43, 95% CI 0.77-7.73) were the most important correlates of HAQ-DI scores > or = 1.0. CONCLUSION Increased HAQ-DI scores at baseline were correlated with reduced fist closure, reduced hand-spread, elevated platelet count, presence of tender joints, older age, and female sex. The most important contributor to functional impairment was hand dysfunction. Even within the first 18 months after SSc onset, moderate-severe functional impairment (HAQ-DI scores > or = 1.0) was frequent (53%) in this group of diffuse SSc patients. In early diffuse SSc, the self-administered HAQ-DI is therefore a valuable assessment of function that correlates with objective physical and laboratory measures of SSc disease involvement. Abnormal HAQ-DI scores may support patient claims of functional impairment, help to focus physician attention on implementing measures to reduce functional impairment, and be useful in reflecting the disease course over time.

Abstract
OBJECTIVE To test the hypothesis that systemic sclerosis (SSc) patients taking high-dose D-penicillamine (D-Pen) would have greater softening of skin, lower frequency of renal crisis, and better survival than patients taking low-dose D-Pen. METHODS Seventeen centers enrolled 134 SSc patients with early (< or =18 months) diffuse cutaneous scleroderma into a 2-year, double-blind, randomized comparison of high-dose D-Pen (750-1,000 mg/day) versus low-dose D-Pen (125 mg every other day). All 134 patients were followed up for a mean+/-SD of 4.0+/-1.1 years to assess the frequencies of new-onset scleroderma renal crisis (SRC) and mortality. RESULTS Sixty-eight patients completed 24 months of drug treatment. The course of the modified Rodnan skin thickness score in the 32 high-dose and the 36 low-dose D-Pen completers was not different at 24 months: the skin score dropped 4.8+/-10.3 (mean+/-SD) units in the high-dose group and 6.9+/-8.4 units in the low-dose group (P = 0.384 by t-test; favoring low-dose D-Pen) from 20.4+/-10.3 in the high-dose and 19.9+/-6.6 in the low-dose D-Pen group at study entry. The incidences of SRC and mortality were not different (P > 0.38 by Cox proportional hazards and by chi-square test) in the 66 high-dose patients (8 developed SRC and 8 died) compared with the 68 low-dose patients (10 developed SRC and 12 died). Of the 20 adverse event-related withdrawals, 80% occurred in the high-dose D-Pen group. CONCLUSION The course of the skin score and the frequencies of SRC and mortality in the high-dose D-Pen group were not different from those in the low-dose D-Pen group. Eighty percent of the adverse event-related withdrawals occurred in the high-dose D-Pen patients. Although this study cannot answer the question of whether low-dose D-Pen is effective, it does suggest that there is no advantage to using D-Pen in doses higher than 125 every other day.

Visual confrontation naming following left anterior temporal lobectomy: a comparison of surgical approaches. Neuropsychology 1999.

Abstract
Change in visual confrontation naming was examined following left (speech dominant) anterior temporal lobectomy (ATL) as a function of surgical technique and patient characteristics. Two hundred seventeen patients with intractable left temporal lobe epilepsy were selected according to standard criteria across 8 centers, and combined into 4 surgical approaches to ATL: (a) tailored resections with intraoperative mapping of eloquent cortex, (b) tailored resections with extraoperative mapping, (c) standard resections with sparing of superior temporal gyrus, and (d) standard resections including excision of superior temporal gyrus. Changes in visual confrontation naming were examined with an index of reliable change derived from an independent sample of 90 nonsurgical patients with complex partial seizures. Results showed significant decline in visual confrontation naming following left ATL, regardless of surgical technique. Across surgical approaches, the risk for decline in visual confrontation naming was associated with a later age of seizure onset and more extensive resection of lateral temporal neocortex.

Abstract
The pharmacokinetic parameters, safety, and tolerability of OptiMARK (gadoversetamide injection), a gadolinium-based magnetic resonance imaging (MRI) contrast agent, were evaluated in 163 subjects with either central nervous system (CNS) or liver pathology with and without renal insufficiency, for which a contrast-enhanced MRI was indicated. A multicenter, double-blind, randomized, placebo-controlled, parallel-group design was used in which subjects received 0.1, 0.3, or 0.5 mmol/kg of OptiMARK or placebo intravenously. Samples were analyzed for total gadolinium by inductively coupled plasma/mass spectrometry. Gadolinium pharmacokinetics were affected by renal impairment: area under the curve, half-life, and steady-state distribution volume significantly increased with declining renal function, while total body clearance decreased. In subjects with normal renal function, neither age, gender, nor liver versus CNS pathology altered gadolinium pharmacokinetics. No clinically significant changes from baseline were noted in vital signs, laboratory measures, electrocardiograms, or physical examinations. OptiMARK is safe and well-tolerated following a single intravenous injection in subjects with either liver or CNS pathology despite a prolonged elimination half-life in subjects with renal impairment.
