Zusammenfassung
Chronisch-entzündliche Darmerkrankungen (Morbus Crohn, Colitis ulcerosa) werden traditionellerweise zu den psychosomatischen
Erkrankungen gez?hlt. In jüngster Zeit wurde diese Zuordnung aber mehrfach in Frage gestellt; zugleich wurden biomedizinische
Faktoren beschrieben, die in der Entstehung und im Verlauf der Erkrankungen eine Rolle spielen k?nnten. Die vorliegende übersichtsarbeit
hat das Ziel, den aktuellen Stand der biomedizinischen und psychosomatischen Forschung zur ?tiologie und Verlaufsgestaltung
bei chronisch-entzündlichen Darmerkrankungen darzustellen und unter methodischen Gesichtspunkten kritisch zu bewerten. Forschungsergebnisse
zu folgenden Themenbereichen werden referiert: Epidemiologie; soziodemographische Merkmale; Genetik; di?tetische Faktoren
und Zigarettenrauchen; Medikamente; Permeabilit?tsst?rung der Darmepithelien; immunologische Faktoren; mikrobiologische Faktoren;
psychiatrische St?rung; emotionale Symptomatik, Pers?nlichkeitsmerkmale; kritische Lebensereignisse und psychosozialer Stre?;
Lebensqualit?t und Krankheitsbew?ltigung.

Summary The dependence of the subjective vertical (SV, the angle between a subjective vertical line and body median plane) on the gravity vertical (body tilt position, angle ) and on the optical vertical (i.e., a field of parallel lines seen as background to the line to be adjusted) was investigated. The SV was measured under dry and wet conditions at different degrees of body tilt attained in either clockwise (CW) or counterclockwise (CCW) progression.The measured difference in between field-of-lines left and right of the line is smallest at the upright position (=O°) and largest at =150°/165°. All body positions show a -difference between CW and CCW attainment (hysteresis), this too being least at upright and greatest at inverted body positions.These results, and changes of with test time, are discussed relative to the hypothesis that efficiency of the statolith organs decreases with body tilt increase, favouring increase of interference of somatoreceptors and the optical reference. 相似文献

Abstract. Comparing the experiences of mystics and victims of delusion we find very similar states of conditions: an experience of abnormal significance, pseudohallucinations, the sense of mission, the suspension of time, extremes of mood, and the sudden and passive appearance. Only the subsequent course of life of those having the experiences makes it possible to distinguish between belief and delusion. The criteria are simple: we find hope and doubt only in relation to mystical experience whereas in delusion we find a paralyzed belief; human freedom increases in belief but is lost in delusion; and belief allows the interaction between the person and society while the person who is deluded has no effectiveness in society. 相似文献

Herzinfarktkranke, die an einer Depression leiden, tragen ein erhöhtes Risiko, in den Folgejahren an einem erneuten Infarkt oder anderen Komplikationen der koronaren Herzkrankheit (KHK) zu sterben. Dass eine Depression, die bei 16–23% der KHK-Patienten auftritt, aber auch schon eine unterschwellige depressive Symptomatik einen unabhängigen prognostischen Faktor der KHK darstellt, konnte in mehreren Studien bestätigt werden. Es ist jedoch noch unklar, ob eine Depression ein kausaler Risikofaktor ist, der den Verlauf der KHK ungünstig beeinflusst, oder lediglich ein Risikoindikator (marker), der zwar eine Vorhersage des Verlaufs erlaubt, diesen aber nicht selbst verändert. Als Bindeglieder zwischen einer Depression und dem Verlauf der KHK werden verhaltensbezogene (verminderte Compliance mit Medikation und risikoreduzierenden Verhaltensempfehlungen) und neurobiologische Mechanismen diskutiert. Am besten untersucht ist die Aktivierung des Hypothalamus-Hypophysen-Nebennierenrinden-Systems und die sympathische Aktivierung (vermehrte Kortisol- und Noradrenalin-Sekretion bei Depression mit der Folge einer erhöhten kardiovaskulären Reaktivität). Weitere potenzielle Bindeglieder umfassen eine verminderte Herzfrequenzvariabilität, stressinduzierte Ischämien, erhöhte Thrombozytenaktivierung und immunologische Dysregulationen. Um die Frage zu klären, ob die Depression ein kausaler Risikofaktor ist, sind Interventionsstudien notwendig, in denen eine depressive Störung erfolgreich behandelt und als Konsequenz auch die Sterblichkeit vermindert wird. Hierzu ist die Befundlage allerdings inkonsistent. Während umfassende, multimodale Interventionsprogramme, die auch eine Modifikation der koronaren Risikofaktoren einschlossen, eine Reduktion von Reinfarktrate und Mortalität demonstrieren konnten, hat eine kürzlich publizierte, große randomisierte Interventionsstudie, in der depressive KHK-Patienten entweder kognitive Verhaltenstherapie oder die übliche Behandlung erhielten, keinen Überlebensvorteil für die Patienten der Behandlungsgruppe zeigen können. Abschließend wird die Befundlage zur Optimierung einer integrierten Versorgung von Patienten mit komorbider Depression dargestellt. 相似文献

The contribution of the insula to motor aspects of speech production: a review and a hypothesis 总被引:10,自引:0,他引:10
Based on clinical and functional imaging data, the left anterior insula has been assumed to support prearticulatory functions of speech motor control such as the "programming" of vocal tract gestures. In order to further elucidate this model, a recent functional magnetic resonance imaging (fMRI) study of our group (Riecker, Ackermann, Wildgruber, Dogil, & Grodd, 200) investigated both overt (aloud) and covert (silent) production of highly overlearned word strings ("automatic speech"), based on the suggestion that "inner speech" might provide a "window" into preparatory motor activities (Jeannerod, 1994). As a control condition, subjects were asked to reproduce a nonlyrical tune. In contrast to hemodynamic responses within motor cortex and cerebellum, activation of the intrasylvian cortex turned out to be bound to overt task performance. Rather than prearticulatory processes, these findings suggest the left insula to contribute to the actual coordination of the up to 100 muscles engaged in articulation and phonation. Conceivably, the association of speech production with intrasylvian cortex might have evolved within the framework of phylogenetically older connections between the insula and limbic structures, on the one hand, and nonspeech functions of the upper midline musculature such as swallowing, on the other. Whereas (overt) speech tasks predominantly elicit activation within left anterior insula, reproduction of a nonlyrical tune yielded an opposite response pattern. Conceivably, the opposite distributional pattern of speaking and singing at the level of intrasylvian cortex reflects operation of the two hemispheres across different time domains ("double filtering by frequency theory": left hemisphere=segmental information, right hemisphere=intonation contours of verbal utterances and musical melodies; ). In line with this suggestion, a further study of our group (Ackermann et al., 2001) provided first evidence that differential hemispheric filtering might be bound to insular cortex. 相似文献

Sit-and-wait strategies in dynamic visual search 总被引:1,自引:0,他引:1
The role of memory in visual search has lately become a controversial issue. Horowitz and Wolfe (1998) observed that performance in a visual search task was little affected by whether the stimuli were static or randomly relocated every 111 ms. Because a memory-based mechanism, such as inhibition of return, would be of no use in the dynamic condition, Horowitz and Wolfe concluded that memory is likewise not involved in the static condition. However, Horowitz and Wolfe could not effectively rule out the possibility that observers adopted a different strategy in the dynamic condition than in the static condition. That is, in the dynamic condition observers may have attended to a subregion of the display and waited for the target to appear there (sit-and-wait strategy). This hypothesis is supported by experimental data showing that performance in their dynamic condition does not differ from performance in another dynamic condition in which observers are forced to adopt a sit-and-wait strategy by being presented with a limited region of the display only. 相似文献

Five competing models specifying the factor structure underlying the Wechsler Memory Scale-Third Edition (D. Wechsler, 1997b) primary subtest scores were evaluated in a sample of patients with intractable temporal lobe epilepsy (N = 254). Models specifying separate immediate and delayed constructs resulted in inadmissible parameter estimates and model specification error. There were negligible goodness-of-fit differences between a 3-factor model of working memory, auditory memory, and visual memory and a nested--more parsimonious--2-factor model of working memory and general memory. The results suggest that specifying a separate visual memory factor provides little advantage for this sample--an unexpected finding in a population with lateralized dysfunction, for which one might have predicted separate auditory and visual memory dimensions. 相似文献

This article addresses potential legal and ethical implications of lawsuits that have been brought when counselors and counseling students have used their religious beliefs as the basis for refusing to counsel lesbian, gay, bisexual, and transexual clients. Four lawsuits are reviewed, issues relevant to the cases are identified, and implications for counselor educators and counseling students are discussed. 相似文献

Repeatedly searching through invariant spatial arrangements in visual search displays leads to the buildup of memory about these displays (contextual-cueing effect). In the present study, we investigate (1) whether contextual cueing is influenced by global statistical properties of the task and, if so, (2) whether these properties increase the overall strength (asymptotic level) or the temporal development (speed) of learning. Experiment 1a served as baseline against which we tested the effects of increased or decreased proportions of repeated relative to nonrepeated displays (Experiments 1b and 1c, respectively), thus manipulating the global statistical properties of search environments. Importantly, probability variations were achieved by manipulating the number of nonrepeated (baseline) displays so as to equate the total number of repeated displays across experiments. In Experiment 1d, repeated and nonrepeated displays were presented in longer streaks of trials, thus establishing a stable environment of sequences of repeated displays. Our results showed that the buildup of contextual cueing was expedited in the statistically rich Experiments 1b and 1d, relative to the baseline Experiment 1a. Further, contextual cueing was entirely absent when repeated displays occurred in the minority of trials (Experiment 1c). Together, these findings suggest that contextual cueing is modulated by observers’ assumptions about the reliability of search environments. 相似文献
