RESUMO
Parental functioning is essential to children's development. Therefore, this cross-sectional single-center study examined the prevalence of family strain in 181 parents and its associations to psychosocial functioning in their children after LT. Median age at LT was one yr. Mean time elapsed since LT was 5.8 yr. The IFS, and the SDQ were applied to parents. Family strain in the present sample was comparable to that in the German normative group of families with a chronically ill or disabled child, but families of LT recipients showed a significantly higher financial impact, impact on coping, and impact on siblings (p < 0.001). Younger age of patients at survey, a more severe clinical course, child's restrictions, and financial losses following LT were determined as significant predictors of family strain (R(2) = 0.42). Parents reported less family strain after living-related compared with deceased donation. Family strain was significantly correlated to psychosocial dysfunction in children post-LT. Present findings demonstrate a risk of maladjustment to the post-LT condition in families. They emphasize the importance of psychological assessment of parents and patients during transplant and follow-up to ensure the best achievable long-term outcome of patients.

BACKGROUND: Exercise may have beneficial effects on both well-being and walking ability in multiple sclerosis (MS). Exercise is shown to be neuroprotective in rodents and may also enhance cognitive function in humans. It may, therefore, be particularly useful for MS patients with pronounced neurodegeneration. OBJECTIVE: To investigate the potential of standardized exercise as a therapeutic intervention for progressive MS, in a randomized-controlled pilot trial. METHODS: Patients with progressive MS and moderate disability (Expanded Disability Status Scale (EDSS) of 4-6) were randomized to one of three exercise interventions (arm ergometry, rowing, bicycle ergometry) for 8-10 weeks or a waitlist control group. We analyzed the drop-out rate as a measure of feasibility. The primary endpoint of the study was aerobic fitness. Secondary endpoints were walking ability, cognitive function as measured by a neuropsychological test battery, depression and fatigue. RESULTS: A total of 42 patients completed the trial (10.6% drop-out rate). Significant improvements were seen in aerobic fitness. In addition, exercise improved walking ability, depressive symptoms, fatigue and several domains of cognitive function. CONCLUSION: This study indicated that aerobic training is feasible and could be beneficial for patients with progressive MS. Larger exercise studies are needed to confirm the effect on cognition.

To date, the course of cognitive development in children after liver transplantation (Ltx) is poorly understood. Cognitive performance, however, is crucial in all developmental stages and for educational achievement. This cross-sectional single-center study examined the prevalence of long-term cognitive impairment in a cohort of 64 pediatric patients after Ltx. Median age at Ltx was 12 months. The revised Wechsler Intelligence Scale IV was administered to assess cognitive performance. Patients were compared with an age- and gender-matched group of children without a chronic health condition. Liver transplanted children performed significantly worse in three of four cognitive domains as well as in the Total Intelligence Quotient (Total IQ) (p = 0.017 to p = 0.005). Liver transplant recipients showed substantially more "serious delays" (IQ < 70) compared to the reference group (9.4% vs. 4.7%). Children with a genetic-metabolic disease performed worse than the other groups in three of the four WISC Indices and in the Total IQ (p = 0.05 to p = 0.01). The strongest association was revealed between height at Ltx and Verbal Comprehension (R(2) = 0.21), Perceptual Reasoning (R(2) = 0.30), Working Memory (R(2) = 0.23) and Total IQ (R(2) = 0.25). Our results indicate a high impact of primary diagnosis and height percentile at Ltx even on children's long-term cognitive performance.

Patients with end-stage renal disease require renal replacement therapy with either dialysis or kidney transplantation. Survival and quality of life (QoL) after transplantation are superior to chronic dialysis. Early living donor kidney transplantation is best for patient and graft survival. Preemptive living-related kidney transplantation therefore is the best medical treatment option for these patients. Patients with end-stage renal disease suffer from multiple physical and psychological complaints. The prevalence of depressive disorders is 20-25% in this population. Studies on QoL in children after kidney transplantation show a reduced physical QoL, but an overall good psychological QoL. Alarming results of numerous studies are the high non-adherence rates in adolescents. Especially exercise interventions during dialysis and after kidney transplantation show promising results. Whether QoL of patients will improve with new approaches to immunosuppressive therapy remains to be evaluated in future studies.

Research on the association between physical activity and mental health addresses the beneficial effects of physical activity on emotional and cognitive functioning. With regard to emotional functioning, most studies focus on the influence of physical activity on depressive symptoms or affective disorders. These studies show that the beneficial effects of aerobic exercise and pharmacotherapy on depressive symptoms seem to be comparable and discuss a variety of neurobiological mechanisms that improve symptoms. The positive effects of physical activity on anxious mood and anxiety disorders are also well documented. Desensitization to physiological changes, improved self-esteem, and self-efficacy seem to play an important part. However, aerobic exercise does not improve mental health in every case, as seen for instance in over-trained athletes. Research on the relationship between physical activity and cognitive functioning reveals that physical activity can prevent the age-related cognitive decline and can delay the onset of dementia. Physical activity has beneficial effects not only on adults but also on children's and adolescents' mental health and cognitive performance, particularly on their executive functions that are still developing throughout adolescence. Finally, physical activity also affects the endocrine stress-regulation system: trained people reveal stronger reactivity and quicker regeneration when faced with stressful events.

Cognitive impairment is one of the most frequent symptoms in patients with multiple sclerosis (MS) but its underlying mechanisms are poorly understood. A number of pathogenetic correlates have previously been proposed including psychosocial factors (such as depression and fatigue), inflammation, neurodegeneration, and neuroendocrine dysregulation. However, these different systems have never been studied in parallel and their differential contributions to cognitive impairment in MS are unknown. We studied a well-characterized cohort of cognitively impaired (CI, n=25) and cognitively preserved (CP, n=25) MS patients based on a comprehensive neuropsychological testing battery, a test of hypothalamo-pituitary-adrenal axis functioning (dexamethasone-corticotropin-releasing hormone suppression test, Dex-CRH test) as well as peripheral blood and MRI markers of inflammatory activity. CI patients had significantly higher disability. In addition, CI patients showed higher levels of fatigue and depression. Fatigue was more closely associated with measures of attention while depression showed strongest correlations with memory tests. Furthermore, percentage of IFNγ-positive CD4+ and CD8+ T cells showed modest correlations with processing speed and working memory. MRI markers of inflammation or global atrophy were not associated with neuropsychological function. Compared to previous studies, the number of patients exhibiting HPA axis hyperactivity was very low and no correlations were found with neuropsychological function. We conclude that fatigue and depression are the main correlates of cognitive impairment, which show domain-specific associations with measures of attention and memory.

AIMS: We investigated interrelations between cognitive abilities, behavioural problems, quality of life and disease-related variables of children after LTX. METHODS: Our sample consisted of 25 children. They were 8.5/2.8 (M/SD) years old and had received the transplant 5.5/3.1 years previously. For assessment we used well-established instruments. RESULTS: Liver transplanted children scored below the population mean on the cognitive as well as on the behavioural instrument and showed scores below average in the scales Self-esteem, Friends and Total Score regarding QoL. Behavioural problems were associated with poorer cognitive performance (r=-0.38 to -0.63). QoL regarding physical well-being was correlated with sequential processing (r=0.41). Lower sequential processing scores were associated with lower QoL. Also between behavioural parameters and QoL correlations could be determined. Children with more behavioural problems experienced lower QoL (r=-0.40 to r=-0.76). Age at onset of disease showed correlations with behavioural and QoL parameters (r=-0.49 resp. r=0.44). Cognitive functioning was associated with medical complications (r=-0.44). CONCLUSIONS: High interrelations between cognitive functioning, behavioural deficits and QoL were obtained. Especially noticeable are correlations between sequential processing and internalized behavioural functions as both are associated with left lateralized brain functioning. This relationship could indicate differential effects on brain development during the preoperative phase.

Interdisciplinary psychoneuroimmunological (PNI) research increasingly demonstrates clinically relevant interrelations between psychological stressors and the onset or progression of chronic diseases. Disturbances of the bi-directional interaction between the nervous system, the immune system and the endocrine system have been hypothesized to be implicated in several diseases. Here, we review evidence from psychoneuroimmunology within the theoretical framework of allostatic load to conceptualize some of these associations. Interdisciplinary PNI research investigating the importance of psychological stress for the higher incidence of infections, decreased responses to vaccinations and delayed wound healing is reviewed. Furthermore, the literature supporting similar associations with regard to progression of oncological diseases and autoimmune disorders is reviewed with a focus on breast cancer and multiple sclerosis. The accumulating evidence regarding the importance of neuroendocrine-immune interaction in these diseases may thus lead to novel insights into pathogenetic mechanisms and could contribute to the development of novel preventive and therapeutic strategies.

BACKGROUND: Fatigue is a major complaint of multiple sclerosis (MS) patients. However, little is known about its pathophysiological mechanisms. Evidence from chronic fatigue syndrome and studies on sickness behaviour suggest that immune and neuroendocrine factors may play a causative role in the development of fatigue. METHODS: We compared whole blood stimulatory capacity for pro- (TNFalpha, IFNgamma) and anti-inflammatory cytokines (IL-10) as well as hypothalamo-pituitary-adrenal (HPA) axis function in 15 MS patients with marked fatigue and 15 patients without fatigue as determined by the Fatigue Severity Scale (FSS). RESULTS: Proinflammatory cytokines were significantly higher (TNFalpha: 478.9 v 228.2 pg/ml, p = 0.01; IFNgamma: 57.6 v 27.8 pg/ml; p = 0.01) in MS patients with fatigue. Furthermore, TNFalpha values significantly correlated with daytime sleepiness as measured by the Epworth Sleepiness Scale (r = 0.64, p = 0.001). Controlling for disease activity (as measured by the Cambridge Multiple Sclerosis Basic Score), disease duration, Expanded Disability Status Scale, and depression further increased the correlation of cytokine production and fatigue. HPA axis activity was not related to fatigue but was modestly correlated with cognitive impairment. CONCLUSION: Our data suggest that fatigue in MS is at least partially mediated through activation of proinflammatory cytokines. In line with earlier findings, HPA axis dysfunction seems not to be relevant in MS fatigue pathogenesis but appears to be linked to cognitive impairment. Our findings suggest that increased levels of inflammatory cytokines may be involved in MS fatigue. Investigation of cytokine profiles may increase the understanding of fatigue pathogenesis in MS.

Epidemiologic studies increasingly have demonstrated a correlation between physical inactivity and certain chronic diseases. Already in the 1970s exercise programs for cardiovascular patients were established, whereas in other severe chronic illnesses such as breast cancer or multiple sclerosis exposure to physical stress seemed to be a contraindication. Today there is a grow ing body of evidence demonstrating positive physical as well as psychic effects of exercise training in patients with these diseases. These studies are summarized and complementary studies of our group are described in more detail. In patients with breast cancer we were able to demonstrate persistent psychosocial effects even 1 year after completion of the training program. In patients with multiple sclerosis we could confirm an induction of neurotrophic factors in trained individuals. Correspondingly, there is accumulating evidence showing positive effects of exercise on cognitive function, especially in the aged. Potential pathophysiological pathways regarding a progression to dementia are presented. Consequently exercise programs could play a pivotal role in the prevention and therapy of the cognitive decline in the aged in an aging society.

OBJECTIVES: The need for an early disclosure of the diagnosis of multiple sclerosis (MS) has become more pressing with the publication of two recent randomized trials which have indicated that very early treatment may favourably alter the disease course. We assessed the current status of diagnostic and therapeutic information on MS from the point of view of patients and neurologists. METHODS: A standardized questionnaire was sent out through the patients' self-help organization in Hamburg, Germany and to all neurologists. RESULTS: A total of 434 of 1300 patients and 80 of 250 neurologists replied. Neurologists gave 90% of the diagnoses but only 50% of patients reported them as the major aid helping to understand the disease. Fifty per cent of patients were not informed about any form of therapy at the time of diagnosis regardless of whether their MS diagnosis was disclosed within the last 5 years or earlier. In contrast to physicians, patients voted for information about a possible MS even if the diagnosis may not yet be clear. CONCLUSION: From the patients' perspective, information about the diagnosis of MS should be more straightforward, and more information about therapies should be provided.

In the List of MAK and BAT Values compounds are designated with 'Sa' ('sensitizing for the airways') or 'Sh' ('sensitizing for the skin') if, according to scientific evidence, they are allergens. Mainly based on suggestions by a WHO working group and based on our own experience, extended criteria have been elaborated by the working group 'skin and allergy' of the Commission of the Deutsche Forschungsgemeinschaft for the Investigation of Health Hazards of Chemical Compounds in the Work Area, which are presented in this article. They serve as guidelines for deciding which substances have to be labelled 'Sa' and 'Sh', respectively, for the prevention of sensitization and subsequent allergic diseases in workers. Although in some special cases their strict application may not be deemed necessary or possible, the proposed new criteria should be used to make the procedure of classification of substances: 1) more rational, 2) more consistent, 3) more comprehensible, and 4) more transparent. This paper informs readers working scientifically or administratively in this field and invites a critical discussion of the issue.

Quality of life (QoL) is discussed as an additional outcome measure in multiple sclerosis (MS). However, few questionnaires assessing disease specific QoL in MS have been published. On the basis of the literature and interviews with clinicians and MS patients, we have developed a disease specific QoL instrument and validated it in a broad range of patients with MS. In this study, a heterogeneous sample of n = 237 MS patients completed the newly developed Hamburg Quality of Life Questionnaire in Multiple Sclerosis (HAQUAMS, in German language) and a battery of already validated questionnaires. They further underwent neurological scoring and objective tests. By these means, we investigated its validity, appropriateness, internal consistency, and retest reliability. Internal consistency and retest coefficients were high and satisfied psychometric standards. Convergent and discriminant validity was supported by direction, magnitude and pattern of correlations with other health measures. HAQUAMS subscales and its total score distinguished between patient groups of varied disease severity, cognitive impairment, and affective symptomatology. No floor or ceiling effects were found in either of the HAQUAMS subscales. The HAQUAMS is a reliable, valid and appropriate instrument for QoL assessment in multiple sclerosis. Data of responsiveness are currently being obtained.

There is only scarce information on the quality of life of child recipients of liver transplants and their families. Particularly children with a living related graft and their families never have been compared to children who received a cadaveric graft and their families. We investigated the following issues in our study: How do parents and children from participating families rate their strain, their quality of life and their relationships within their family? Do families with a living - related donor differ from those with a cadaveric donor? What do living donors and their partners think about the donation retrospectively? The study was conducted with 106 participants from 50 families (42 mothers, 40 fathers, and 24 children older than 6 years). In 20 of these families, a living transplantation had been performed. Participants were interviewed and asked to fill out several questionnaires. School-aged children with a liver transplant show good social integration among their peers and in school. The child's disease, however, has a great impact on the family. Family members show a reduction in social contact, and an increase in marital crises, and problematic relations amongst siblings. Families in which a cadaveric graft was performed, are less satisfied with life, and show more symptoms of exhaustion. Every family studied possessed or acquired - a high degree of internal or external coping resources. Living - related donors tried hard to obtain an understanding of the medical context. The partner, rather than the donor himself, feels anxious before the donation. The limited time available for the decision to donate is not perceived by the donors to be critical. Ten percent of living donors feel "a little" that their health is affected. The decision to donate is supported "strongly" or "very strongly" by the partners in 80 % of the cases. A possible strain on the child through the expectation of gratitude by the donor is stated by 20 %. All of the donors agree that if they were to be asked today, they would donate again, only one of the partners raised objections. In summary, as a retrospective pilot study, this study primarily generates hypotheses rather than testing them and helps to develop research tools for the field. Results suggest that a psychological support be made available both prior to and following the operation, not only for the children but also for their families, with particular attention to the partners of the living donors and the siblings of the affected children.

The diagnostic value of the lymphocyte transformation test (BeLT) and the intracutaneous skin test with berylliumsulfate was addressed in 13 patients with chronic berylliosis, and 15 individuals with occupational exposure. Additionally, patients with sarcoidosis (n = 21), tuberculosis (n = 14) and healthy controls (n = 25) were tested with BeLT and yielded negative results. In chronic berylliosis the BeLT was positive in 10/13. In 3/13 the BeLT was negative, but the skin test positive. 6/15 exposed individuals exhibited a positive BeLT. The time course of the skin test differed markedly between the individual berylliosis patients. Typical granulomas were present in 4/10 cases. In 9 exposed individuals BeLT tested negative. Additionally, skin tests were negative in 7 exposed patients, however, unspecific skin reactions were observed in 3 cases. The diagnostic value of Beryllium IT requires further investigation. At present, BeLT appears to be a suitable test to prove beryllium sensitisation.
