Guidelines for treatment of atopic eczema (atopic dermatitis) Part II

The existing evidence for treatment of atopic eczema (atopic dermatitis, AE) is evaluated using the national standard Appraisal of Guidelines Research and Evaluation. The consensus process consisted of a nominal group process and a DELPHI procedure. Management of AE must consider the individual symptomatic variability of the disease. Basic therapy is focused on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin inhibitors (TCI) is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the TCI tacrolimus and pimecrolimus are preferred in certain locations. Systemic immune-suppressive treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial treatment. Adjuvant therapy includes UV irradiation preferably with UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. 'Eczema school' educational programs have been proven to be helpful. Pruritus is targeted with the majority of the recommended therapies, but some patients need additional antipruritic therapies.

Investigating the Role of System Justification in Mental Illness Stigma

The current study integrates system justification theory with research on mental illness stigma. Stereotypes of both low- and high-status groups in society can be a means of satisfying the system justification motive, or the motive to view societal inequalities as justified (as reviewed in Jost, Banaji, & Nosek, 2004). Corrigan, Watson, and Ottati (2003) proposed that system justification theory may be able to explain the origins of particular stereotypes of people with mental illness, such as dangerousness and incompetence. The primary goal of the present study was to investigate whether the stigmatization of people with mental illness – a specific form of stigmatization of a lowstatus group – can be at least partially attributed to a broader motive to justify societal inequalities. To test this, the current study included both an experimental manipulation of the perceived legitimacy of the social system and a measure of system-justifying beliefs. Stigmatization of individuals with mental illness was measured with both explicit selfreport measures (semantic differentials and the Attribution Questionnaire) and an implicit measure (a computer-based Implicit Association Test). The relationships between participant characteristics, such as personal experience with mental illness, and stigma were also investigated. Consistent with past research demonstrating only modest correlations between explicit and implicit stigma, greater self-reported fear toward a person with a chronic mental illness was weakly associated with increased implicit bias against mental illness in favor of physical disability. There was little support for the involvement of system justification in explicit stigma. Participants with personal experience with mental illness were less likely to self-report fear and avoidance of a person with a chronic mental illness. These findings have implications for stigmareduction efforts.

Assessment of Alcohol Reward in Prairie Voles (Microtus ochrogaster)

The purpose of our study was to assess whether prairie voles find alcohol rewarding. Prairie voles have recently become a species of interest for alcohol studies, which have traditionally used other rodent model species including several different strains of mice and rats. The prairie vole is one of only two known rodent species that readily administers high levels of unsweetened alcohol, implicating it as a potentially effective animal model for studying alcohol abuse. However, voluntary consumption does not necessarily imply that prairie voles find it rewarding. Therefore the purpose of our study was to investigate if alcohol has rewarding properties for prairie voles using three different approaches: place conditioning, flavor conditioning, and immunohistochemistry. Furthermore, we sought to characterize their reward profile and compare it to other commonly used rodent models ¿ C57BL/6 mice, DBA/2J mice, and Sprague-Dawley rats. Place and flavor conditioning are behavioral methods that rely on the learned association between a stimulus and the effects of a drug; the drug of interest in these studies is alcohol. To assess whether prairie voles will demonstrate a conditioned preference for alcohol-paired stimuli, seven place conditioning studies were run that investigated a range of different doses, individual conditioning session durations, and trial durations. Video analysis revealed no difference in the amount of time spent on the alcohol-paired floor, suggesting no conditioned place preference for alcohol. Two flavor conditioning tests were conducted to assess whether voles would demonstrate a preference for an alcohol-paired flavored saccharin solution. Voles demonstrated reduced consumption of the alcohol-paired flavored saccharin solution, regardless of dose or flavor, when alcohol administration occurred after conditioning sessions (p=<0.001). When alcohol was administered before conditioning sessions, no difference in consumption of the alcohol-paired and saline-paired flavored saccharin solutions was seen (p=0.545). Previous studies that have documented similar behavior have hypothesized that this is an example of an anticipatory contrast effect. This theory proposes that prairie voles reduce their intake of a hedonic solution (flavored saccharin solution) in anticipation of later drug administration (alcohol). However, conditioning-based behavioral methods of studying alcohol reward are highly sensitive to the parameters of the conditioned stimulus, thus it is possible that voles will not show preference for alcohol-related stimuli, even if they do find alcohol rewarding. Immunohistochemical analysis supplemented this behavioral data by allowing us to identify specific neural regions that were directly activated in response to the acute administration of alcohol. No difference in the number of activated c-Fos neurons in the Nucleus Accumbens (NAc) core or shell was seen (p=0.3364; p=0.6698) in animals that received an acute injection of alcohol or saline. There was a significant increase in the number of activated c-Fos neurons in the Paraventricular Nucleus of the Hypothalamus (PVN) in alcohol-treated animals compared to saline-treated animals (p=0.0034). There was no difference in the pixel count of activated c-Fos neurons or in the % area activated in the Arcuate Nucleus between alcohol and saline-treated animals (p=0.4523; p=0.3304). In conclusion, the place conditioning studies that were conducted in this thesis suggest that prairie voles do not demonstrate preference or aversion towards alcohol-paired stimuli. The flavor conditioning studies suggest that prairie voles do not demonstrate aversion but rather avoidance of the alcohol-paired flavor in anticipation of future alcohol administration. The preliminary immunohistochemical data collected is inconclusive but cannot rule out the possibility of neuronal activation patterns indicative of reward. Taken together, our data indicate that prairie voles hav

Facing the dreaded: does mindfulness facilitate coping with distressing experiences? A moderator analysis

Increasing evidence shows that mindfulness is positively related to mental health; however, the nature of this relationship is not fully understood. The current study used structural equation modeling to investigate the hypothesis that mindfulness moderates the association between the occurrence of unavoidable distressing experiences (UDE) and mental health. Participants from a community sample (N = 376) completed the Freiburg Mindfulness Inventory, the Positive and Negative Affect Scale, the Brief Symptom Inventory, the Inventory of Approach and Avoidance Motivation, and the Incongruence Scale. Results indicated that mindfulness moderated the association between unavoidable distressing events and psychopathological symptoms/negative affect. Thus, mindfulness may contribute to enhance the ability to cope with UDE and thus mitigate the detrimental effects of these experiences on mental health.

[House dust mite allergy]

House dust mites can be found all over the world where human beings live independent from the climate. Proteins from the gastrointestinal tract- almost all known as enzymes - are the allergens which induce chronic allergic diseases. The inhalation of small amounts of allergens on a regular base all night leads to a slow beginning of the disease with chronically stuffed nose and an exercise induced asthma which later on persists. House dust mites grow well in a humid climate - this can be in well isolated dwellings or in the tropical climate - and nourish from human skin dander. Scales are found in mattresses, upholstered furniture and carpets. The clinical picture with slowly aggravating complaints leads quite often to a delayed diagnosis, which is accidently done on the occasion of a wider spectrum of allergy skin testing. The beginning of a medical therapy with topical steroids as nasal spray or inhalation leads to a fast relief of the complaints. Although discussed in extensive controversies in the literature - at least in Switzerland with the cold winter and dry climate - the recommendation of house dust mite avoidance measures is given to patients with good clinical results. The frequent ventilation of the dwelling with cold air in winter time cause a lower indoor humidity. Covering encasings on mattresses, pillow, and duvets reduces the possibility of chronic contact with mite allergens as well as the weekly changing the bed linen. Another option of therapy is the specific immunotherapy with extracts of house dust mites showing good results in children and adults. Using recombinant allergens will show a better quality in diagnostic as well as in therapeutic specific immunotherapy.

Cross-sectional observational study of 208 patients with non-classical urea cycle disorders

Urea cycle disorders (UCDs) are inherited disorders of ammonia detoxification often regarded as mainly of relevance to pediatricians. Based on an increasing number of case studies it has become obvious that a significant number of UCD patients are affected by their disease in a non-classical way: presenting outside the newborn period, following a mild course, presenting with unusual clinical features, or asymptomatic patients with only biochemical signs of a UCD. These patients are surviving into adolescence and adulthood, rendering this group of diseases clinically relevant to adult physicians as well as pediatricians. In preparation for an international workshop we collected data on all patients with non-classical UCDs treated by the participants in 20 European metabolic centres. Information was collected on a cohort of 208 patients 50% of which were ≥ 16 years old. The largest subgroup (121 patients) had X-linked ornithine transcarbamylase deficiency (OTCD) of whom 83 were female and 29% of these were asymptomatic. In index patients, there was a mean delay from first symptoms to diagnosis of 1.6 years. Cognitive impairment was present in 36% of all patients including female OTCD patients (in 31%) and those 41 patients identified presymptomatically following positive newborn screening (in 12%). In conclusion, UCD patients with non-classical clinical presentations require the interest and care of adult physicians and have a high risk of neurological complications. To improve the outcome of UCDs, a greater awareness by health professionals of the importance of hyperammonemia and UCDs, and ultimately avoidance of the still long delay to correctly diagnose the patients, is crucial.

The Permanent Income Hypothesis: A Test on Czech Privatisation

Since the late eighties, economists have been regarding the transition from command to market economies in Central and Eastern Europe with intense interest. In addition to studying the transition per se, they have begun using the region as a testing ground on which to investigate the validity of certain classic economic propositions. In his research, comprising three articles written in English and totalling 40 pages, Mr. Hanousek uses the so-called "Czech national experiment" (voucher privatisation scheme) to test the permanent income hypothesis (PIH). He took as his inspiration Kreinin's recommendation: "Since data concerning the behaviour of windfall income recipients is relatively scanty, and since such data can constitute an important test of the permanent income hypothesis, it is of interest to bring to bear on the hypothesis whatever information is available". Mr. Hanousek argues that, since the transfer of property to Czech citizens from 1992 to 1994 through the voucher scheme was not anticipated, it can be regarded as windfall income. The average size of the windfall was more than three month's salary and over 60 percent of the Czech population received this unexpected income. Furthermore, there are other reasons for conducting such an analysis in the Czech Republic. Firstly, the privatisation process took place quickly. Secondly, both the economy and consumer behaviour have been very stable. Thirdly, out of a total population of 10 million Czech citizens, an astonishing 6 million, that is, virtually every household, participated in the scheme. Thus Czech voucher privatisation provides a sample for testing the PIH almost equivalent to a full population, thus avoiding problems with the distribution of windfalls. Compare this, for instance with the fact that only 4% of the Israeli urban population received personal restitution from Germany, while the number of veterans who received the National Service Life Insurance Dividends amounted to less than 9% of the US population and were concentrated in certain age groups. But to begin with, Mr. Hanousek considers the question of whether the public percieves the transfer from the state to individual as an increase in net wealth. It can be argued that the state is only divesting itself of assets that would otherwise provide a future source of transfers. According to this argument, assigning these assets to individuals creates an offsetting change in the present value of potential future transfers so that individuals are no better off after the transfer. Mr. Hanousek disagrees with this approach. He points out that a change in the ownership of inefficient state-owned enterprises should lead to higher efficiency, which alone increases the value of enterprises and creates a windfall increase in citizens' portfolios. More importantly, the state and individuals had very different preferences during the transition. Despite government propaganda, it is doubtful that citizens of former communist countries viewed government-owned enterprises as being operated in the citizens' best interest. Moreover, it is unlikely that the public fully comprehended the sophisticated links between the state budget, state-owned enterprises, and transfers to individuals. Finally, the transfers were not equal across the population. Mr. Hanousek conducted a survey on 1263 individuals, dividing them into four monthly earnings categories. After determining whether the respondent had participated in the voucher process, he asked those who had how much of what they received from voucher privatisation had been (a) spent on goods and services, (b) invested elsewhere, (c) transferred to newly emerging pension funds, (d) given to a family member, and (e) retained in their original form as an investment. Both the mean and the variance of the windfall rise with income. He obtained similar results with respect to education, where the mean (median) windfall for those with a basic school education was 13,600 Czech Crowns (CZK), a figure that increased to 15,000 CZK for those with a high school education without exams, 19,900 CZK for high school graduates with exams, and 24,600 CZK for university graduates. Mr. Hanousek concludes that it can be argued that higher income (and better educated) groups allocated their vouchers or timed the disposition of their shares better. He turns next to an analysis of how respondents reported using their windfalls. The key result is that only a relatively small number of individuals reported spending on goods. Overall, the results provide strong support for the permanent income hypothesis, the only apparent deviation being the fact that both men and women aged 26 to 35 apparently consume more than they should if the windfall were annuitised. This finding is still fully consistent with the PIH, however, if this group is at a stage in their life-cycle where, without the windfall, they would be borrowing to finance consumption associated with family formation etc. Indeed, the PIH predicts that individuals who would otherwise borrow to finance consumption would consume the windfall up to the level equal to the annuitised fraction of the increase in lifetime income plus the full amount of the previously planned borrowing for consumption. Greater consumption would then be financed, not from investing the windfall, but from avoidance of future repayment obligations for debts that would have been incurred without the windfall.

A New Symbiosis: Municipalities, Private Contractors and Non-Governmental Organisations for the Provision of Local Public Services"

This project considered the second stage of transforming local administration and public service management to reflect democratic forms of government. In Hungary in the second half of the 1990s more and more public functions delegated to local governments have been handed over to the private or civil sectors. This has led to a relative decrease of municipal functions but not of local governments' responsibilities, requiring them to change their orientation and approach to their work so as to be effective in their new roles of managing these processes rather than traditional bureaucratic administration. Horvath analysed the Anglo-Saxon, French and German models of self-government, identifying the differing aspects emphasised in increasing the private sector's role in the provision of public services, and the influence that this process has on the system of public administration. He then highlighted linkages between actors and local governments in Hungary, concluding that the next necessary step is to develop institutional mechanisms, financial incentives and managerial practices to utilise the full potential of this process. Equally important is the need for conscious avoidance of restrictive barriers and unintended consequences, and for local governments to confront the social conflicts that have emerged in parallel with privatisation. A further aspect considered was a widening of the role of functional governance at local level in the field of human services. A number of different special purpose bodies have been set up in Hungary, but the results of their work are unclear and Horvath feels that this institutionalisation of symbiosis is not the right path in Hungary today. He believes that the change from local government to local governance will require the formulation of specific public policy, the relevance of which can be proven by processes supported with actions.

Changes in Psychological Characteristics of Working Adults in Different Stages of Economic Transition in Lithuania

Global economic changes have psychological consequences and Mr. Lepeska set out to assess these changes in working adults in Lithuania between 1993 and 1997. He surveyed two groups of working adults, with a total of 200 people, randomly selected and representing different organisations and professions. In both groups around 30% of participants were managers, with the remainder working in non-managerial positions. The participants were surveyed twice, once in 1993 and the second time in 1997,using various psychodiagnostic tools to measure their psychological characteristics. The results showed that strategies for coping with stress have changed, with problem solving strategies being used more often, and avoidance behaviour or seeking social support less. Men tended to have rejected these strategy more radically than women. Attitudes towards work had become more positive, with managers' attitudes having changed more significantly than those of employees from lower levels of organisations. Younger people were more positive towards work-related changes, while situational anxiety tended to increase with age, although overall it remained low. Mr. Lepeska found that while there were some indications of an increasing individualist in relation to peers, the traditional collective orientation of Lithuanian adults had if anything increased. People have become more accepting of an unequal distribution of power, making it difficult to increase the participation of subordinates in decision making. He also noted a tendency for Lithuanians to see their organisations as traditional families, expecting them to take care of them physically and economically in return for loyalty. The strong feminine orientation with its stress on interpersonal relations and overall quality of life has also strengthened, but the ability of Lithuanians to take initiative and control their environment was relatively low. Mr. Lepeska concludes that organisations should seek to recruit people who are able to adjust more easily to changes and consider measuring dominance, individualism, and attitudes to work-related change and situational anxiety in the process of professional selection. There should also be more emphasis on team building and on training managers to maintain closer relationships with their subordinates so as to increase the latter's participation in decision making. Good interpersonal relations can be a strong work motivator, as may be special attention to the security needs of older employees.

Colour Symbolism, Colour Preference in Hungarian Folklore and Folk Architecture"

The Hungarian way of decoration has certain characteristics which are rooted in the deep symbolism of ancient Hungarian mythical thinking. The ancient heritage of the Hungarians' former homeland somewhere in the Urals included eastern elements. During their migrations, the Hungarian tribes met other eastern peoples and their culture of decoration became mixed with elements drawn from these new contacts. These diverse influences mean that the Hungarian way of thinking, building and ornamentation show a certain dualism of Puritanism and rationalism in the creation of space and manufacturing, and rich fantasy in decoration and ornamentation. The Hungarians use coloured ornamentation to emphasise the symbolic importance of details. The colouring system of the built environment shows the same dualism: the main colour of the facades and inner walls is white, while the furniture, textiles, gates and windows, and sometimes the gable and fireplace are richly decorated. In Hungarian symbolism, the house and settlement are a model of the universe, so their different parts also have a transcendent meaning. The traditional meanings of the different colours reflect this transcendence. Each colour has ambivalent meanings: RED - the colour of blood - means violence and love. YELLOW - means sickness, death and ripeness (golden yellow). BLUE - means innocence, eternity (light blue) and old age, death (dark blue). BLACK - can be both ceremonial and mourning. WHILE - can have sacred meaning (bright white), while yellowish white fabric is the most common garb of both men and women in village society. GREEN - the only colour without a dual meaning, symbolises the beginning of life. Until the late 18th and early 19th centuries Hungarian folk art used one or two-coloured decoration (red, black, blue, red-blue or red-black), and from the early 19th century it moved to multi-coloured decoration. Colours are characteristically used in complementary contrast, with bright colours on a plain ground and an avoidance of subtle shadings.

To look or not to look at threat? Scanpath differences within a group of spider phobics

Predicting the behavior of phobic patients in a confrontational situation is challenging. While avoidance as a major clinical component of phobias suggests that patients orient away from threat, findings based on cognitive paradigms indicate an attentional bias towards threat. Here we present eye movement data from 21 spider phobics and 21 control subjects, based on 3 basic oculomotor tasks and a visual exploration task that included close-up views of spiders. Relative to the control group, patients showed accelerated reflexive saccades in one of the basic oculomotor tasks, while the fear-relevant exploration task evoked a general slowing in their scanning behavior and pronounced oculomotor avoidance. However, this avoidance strongly varied within the patient group and was not associated with the scores from spider avoidance-sensitive questionnaire scales. We suggest that variation of oculomotor avoidance between phobics reflects different strategies of how they cope with threat in confrontational situations.

Long-lasting reactivity and high frequency of drug-specific T cells after severe systemic drug hypersensitivity reactions

BACKGROUND: Drug-reactive T cells are involved in most drug-induced hypersensitivity reactions. The frequency of such cells in peripheral blood of patients with drug allergy after remission is unclear. OBJECTIVE: We determined the frequency of drug-reactive T cells in the peripheral blood of patients 4 months to 12 years after severe delayed-type drug hypersensitivity reactions, and whether the frequency of these cell differs from the frequency of tetanus toxoid-reactive T cells. METHODS: We analyzed 5 patients with delayed-type drug hypersensitivity reactions, applying 2 methods: quantification of cytokine-secreting T cells by enzyme-linked immunospot (ELISpot), and fluorescent dye 5,6-carboxylfluorescein diacetate succinimidyl ester (CFSE) intensity distribution analysis of drug-reactive T cells. RESULTS: Frequencies found were between 0.02% and 0.4% of CD4(+) T cells reacting to the respective drugs measured by CFSE analysis, and between 0.01% and 0.08% of T cells as determined by ELISpot. Reactivity was seen neither to drugs to which the patients were not sensitized nor in healthy individuals after stimulation with any of the drugs used. CONCLUSION: About 1:250 to 1:10,000 of T cells of patients with drug allergy are reactive to the relevant drugs. This frequency of drug-reactive T cells is higher than the frequency of T cells able to recognize recall antigens like tetanus toxoid in the same subjects. A substantial frequency could be observed as long as 12 years later in 1 patient even after strict drug avoidance. Patients with severe delayed drug hypersensitivity reactions are therefore potentially prone to react again to the incriminated drug even years after strict drug avoidance.

Evidence for low-grade systemic proinflammatory activity in patients with posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) may increase cardiovascular risk but the psychophysiological mechanisms involved are elusive. We hypothesized that proinflammatory activity is elevated in patients with PTSD as diagnosed by the Clinician Administered PTSD Scale (CAPS) interview. Plasma levels of proinflammatory C-reactive protein (CRP), interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha, and of anti-inflammatory IL-4 and IL-10 were measured in 14 otherwise healthy PTSD patients and in 14 age- and gender-matched healthy non-PTSD controls. Levels of TNF-alpha (p=0.038; effect size Cohen's d=0.58) and of IL-1beta (p=0.075, d=0.68) were higher in patients than in controls. CRP (d=0.10), IL-6 (d=0.18), IL-4 (d=0.42), and IL-10 (d=0.37) were not significantly different between groups. Controlling for traditional cardiovascular risk factors, mood, and time since trauma revealed lower IL-4 in patients than in controls (p=0.029) and rendered group differences in TNF-alpha and IL-1beta insignificant. In all subjects, TNF-alpha correlated with total (frequency and intensity) PTSD symptom cluster of re-experiencing (r=0.49, p=0.008), avoidance (r=0.37, p=0.050), and hyperarousal (r=0.42, p=0.026), and with PTSD total symptom score (r=0.37, p=0.054). Controlling for time since trauma attenuated these associations. The correlation between IL-1beta and total avoidance symptoms (r=0.42, p=0.028) became insignificant when controlling for anxiety and depression. IL-4 correlated with total hyperarousal symptoms (r=-0.38, p=0.047), and after controlling for systolic blood pressure and smoking status, with PTSD total symptom score (r=-0.41, p=0.035). PTSD patients showed a low-grade systemic proinflammatory state, which, moreover, was related to PTSD symptom levels suggesting one mechanism by which PTSD could contribute to atherosclerotic disease.

Feelings of revenge, retaliation motive, and posttraumatic stress reactions in crime victims

Individuals with posttraumatic stress disorder (PTSD) are often said to experience strong feelings of revenge. However, there is a need for confirmatory empirical studies. Therefore, in a study of 174 victims of violent crimes, the relation between feelings of revenge and posttraumatic stress reactions was investigated. Feelings of revenge were correlated with intrusion and hyperarousal but not with avoidance. Feelings of revenge explained incremental variance of intrusion and hyperarousalwhen the variance explained by victimological variables was controlled. The retaliation motive implied in feelings of revenge did not account for the relation between feelings of revenge and posttraumatic stress reactions. However, the relation was moderated by the time since victimization. Therefore, feelings of revenge must presumably be regarded as a maladaptive coping reaction to experienced injustice, but not in the first period after victimization.
