Coordination dynamics of circulatory and respiratory rhythms during psychomotor drive reduction.

A 0.15-Hz rhythm band in cutaneous blood oscillations in awake human subjects was studied in cardiovascular-respiratory time series of five subjects relaxing naïvely or practicing hypnoid relaxation (autogenic training, or AT). Time series analysis used nonlinear algorithms, time-frequency distribution (TFD), postevent scan (PES) method, and linear fast Fourier transform (FFT) algorithm. This 0.15-Hz rhythm band caused phase synchronization with respiration at 1:2, 1:1, and 2:1 integer number (n/m) ratios for extended periods. During wave epochs, the 0.15-Hz rhythm band was amplified, causing the 0.15-Hz rhythm band to also appear in interbeat intervals and arterial blood pressure fluctuations. If phase synchronization of the 0.15-Hz rhythm band with respiration was established at a 1:1 integer number ratio, it was maintained and resulted in consensualization of all cardiovascular-respiratory oscillations at this frequency. Simultaneous cardiovascular and respiratory oscillations at about 0.1 Hz did not affect the appearance of the 0.15-Hz rhythm band in the photoplethysmography (PPG) signal. Recent evidence suggests the emergence of the 0.15-Hz rhythm band and n/m phase synchronization to result from nonequilibrium phase transitions operational in the network of lower brainstem neurons and associated parasympathetic neuronal effectors. These findings corroborate our notion of the 0.15-Hz rhythm band as a marker of the trophotropic mode of operation.

[Psychological trauma in trauma medicine--the current status of psychological management of trauma victims in Germany].

A clinically significant amount of accident victims display psychological disorders as a reaction to the trauma. Outcome studies on multiple trauma emphasize that life quality following severe accidental injury is influenced by early diagnosis and treatment of psychic co-morbidity. In a nationwide survey concerning the state of the art in in-patient treatment of injury patients conducted in Germany, every surgical ward was contacted and physicians were asked about their standard procedures of detecting and treating psychotraumatic complications. The results of the survey indicate that surgeons pay close attention to signs of psychological comorbidity and have good basic knowledge of psychotraumatic disorders. Nevertheless, there are structural deficiencies caused by the fact that only a few wards have staff specially trained in psychotraumatological care. Only a minority of patients is treated for psychotraumatic symptoms. In view of the high prevalence rates for psychotraumatic disorders in the aftermath of severe accidental injuries, the article discusses the need for psychic diagnosis and support as well as the necessary cooperative structures required in the model of Integrative Posttraumatic Acute Care.

[Concepts of anthropological medicine].

Medical anthropology is the teaching of the ill human being, of being ill; anthropological medicine is the realization of this teaching in practice. This concept was first developed and assessed in the "Gestaltkreis" and in the Pathosophy (44), in Medicine in Motion (39), and in the Bipersonality (10). The four most important concepts are represented, which have their origin and aim in anthropological medicine: anthropological medicine, Balint-work, family-oriented medicine, and salutogenesis. These concepts are exemplified in the Aachen psychosomatic liaison model, the Aachen Balint cooperation model, and the Aachen model of psychosomatic care. We wish to portray the meaning of these resources for the medicine of the future, since they have proven to be effective, cost-saving, and easy to be handled. In the latter part of our presentation, we will document this point with a pilot study conducted in Israel and in our own clinic in Aachen.

[Treatment and responsibility ethics in dealing with severely ill and dying patients--discussion stimulation].

As we are approaching the end of this century, the implicit axiom which addresses the question of responsibility within the new territory of collaborative medical practising that was entered with high-tech medicine, has still to be put into new places. As for ethical theories, there is no such thing as a no mans land. All reflections will reach sooner or later the limits of language, and so will reflections on the ethics of action and the ethics of responsibility. According to Ludwig Wittgenstein we call running up against the limits of language ethics. In clinical psychosomatic medicine interacting with those who are severely ill and those who are dying everything is enmeshed: religion and philosophy, medicine, technology and language. For the ethics of action this is represented e.g. by a collective search for a consensus in clinical-psychosomatic case conferences. By the reassurance through others we can relate when being active to two imperatives by H.Y. Förster (1984): firstly, if you wish to understand, learn to act! Secondly, act always in a fashion that will open up new possibilities. In ethics of responsibility we can relate to the inheritance of monotheistic religions, upon the God of Israel and to tolerance.

[Psychosocial stress and utilization of medical services after coronary bypass operation].

This study examines the relationship between psychosocial stress and social support before coronary surgery and the amount of health care utilization in a sample of 136 patients during postoperative hospitalization. The aim of the study is to test the hypothesis that there is a correlation between a high psychosocial stress profile and the utilization of medical care (so called high utilizers). The sample consists of 80.7% men and 19.3% women aged between 31 and 78 years (mean 64; sd 9.1). In this first data analysis psychosocial impact is assessed by anxiety, depression and social support (HADS-D, F-SOZU). Detailed somatic factors concerning severity of the illness, inpatient course and the utilization of health care (medication, technical examinations, consultations) are assessed by means of a documentation system. With regard to anxiety, depression and social support the sample is located within the normal range. In contrast to our expectations the results show that high scores of anxiety and depression as well as a low level of emotional support do not correlate significantly with an increased use of medication, the number of consultations and technical examinations. Furthermore no correlation has been found between the length of hospitalization and preoperative comorbidity as compared to the mentioned psychosocial stress variables. On the other hand the data analysis showed that about 30% of the patients during the postoperative period utilize about half of the total amount of the different medical treatments. In the postoperative period these high utilizers cannot be distinguished from the other patients, neither by sociodemographic variables nor by means of an increased psychosocial stress or severity of illness.
