Ein neues psychoendokrin-validiertes Verfahren zur Erfassung von Stressbewältigungsfertigkeiten (ISBF)

Background: We previously found good psychometric properties of the Inventory for assessment of stress management skills (German translation: Inventar zur Erfassung von Stressbewältigungsfertigkeiten), ISBF, a short questionnaire for combined assessment of different perceived stress management skills in the general population. Here, we investigate whether stress management skills as measured by ISBF relate to cortisol stress reactivity in two independent studies, a laboratory study (study 1) and a field study (study 2). Methods: 35 healthy non-smoking and medication-free men in study 1 (age mean±SEM:38.0±1.6) and 35 male and female employees in study 2 (age mean±SEM:32.9±1.2) underwent an acute standardized psychosocial stress task combining public speaking and mental arithmetic in front of an audience. We assessed stress management skills (ISBF) and measured salivary cortisol before and after stress and several times up to 60 min (study 2) and 120 min (study 1) thereafter. Potential confounders were controlled. Results:. General linear models controlling for potential confounders revealed that in both studies, higher stress management skills (ISBF total score) were independently associated with lower cortisol levels before and after stress (main effects ISBF: p’s<.055) and lower cortisol stress reactivity (interaction ISBF-by-stress: p’s<.029). Post-hoc-testing of ISBF subscales suggest lower cortisol stress reactivity with higher “relaxation abilities” (both studies) and higher scores in the scale “cognitive strategies and problem solving” (study 2). Conclusions: Our findings suggest blunted increases in cortisol following stress with increasing stress management skills as measured by ISBF. This suggests that the ISBF not only relates to subjective psychological but also objective physiological stress indicators which may further underscore the validity of the questionnaire.

Stress and hemostasis: an update

Numerous naturalistic, experimental, and mechanistic studies strongly support the notion that-as part of fight-or-flight response-hemostatic responses to acute psychosocial stress result in net hypercoagulability, which would protect a healthy organism from bleeding in case of injury. Sociodemographic factors, mental states, and comorbidities are important modulators of the acute prothrombotic stress response. In patients with atherosclerosis, exaggerated and prolonged stress-hypercoagulability might accelerate coronary thrombus growth following plaque rupture. Against a background risk from acquired prothrombotic conditions and inherited thrombophilia, acute stress also might trigger venous thromboembolic events. Chronic stressors such as job strain, dementia caregiving, and posttraumatic stress disorder as well as psychological distress from depressive and anxiety symptoms elicit a chronic low-grade hypercoagulable state that is no longer viewed as physiological but might impair vascular health. Through activation of the sympathetic nervous system, higher order cognitive processes and corticolimbic brain areas shape the acute prothrombotic stress response. Hypothalamic-pituitary-adrenal axis and autonomic dysfunction, including vagal withdrawal, are important regulators of hemostatic activity with longer lasting stress. Randomized placebo-controlled trials suggest that several cardiovascular drugs attenuate the acute prothrombotic stress response. Behavioral interventions and psychotropic medications might mitigate chronic low-grade hypercoagulability in stressed individuals, but further studies are clearly needed. Restoring normal hemostatic function with biobehavioral interventions bears the potential to ultimately decrease the risk of thrombotic diseases.

Childhood Trauma and PTSD symptoms increase the risk of cognitive impairment in a sample of former indetured child laborers in old Age.

A growing body of evidence suggests a link between early childhood trauma, post-traumatic stress disorder (PTSD) and higher risk for dementia in old age. The aim of the present study was to investigate the association between childhood trauma exposure, PTSD and neurocognitive function in a unique cohort of former indentured Swiss child laborers in their late adulthood. To the best of our knowledge this is the first study ever conducted on former indentured child laborers and the first to investigate the relationship between childhood versus adulthood trauma and cognitive function. According to PTSD symptoms and whether they experienced childhood trauma (CT) or adulthood trauma (AT), participants (n = 96) were categorized as belonging to one of four groups: CT/PTSD+, CT/PTSD-, AT/PTSD+, AT/PTSD-. Information on cognitive function was assessed using the Structured Interview for Diagnosis of Dementia of Alzheimer Type, Multi-infarct Dementia and Dementia of other Etiology according to ICD-10 and DSM-III-R, the Mini-Mental State Examination, and a vocabulary test. Depressive symptoms were investigated as a potential mediator for neurocognitive functioning. Individuals screening positively for PTSD symptoms performed worse on all cognitive tasks compared to healthy individuals, independent of whether they reported childhood or adulthood adversity. When controlling for depressive symptoms, the relationship between PTSD symptoms and poor cognitive function became stronger. Overall, results tentatively indicate that PTSD is accompanied by cognitive deficits which appear to be independent of earlier childhood adversity. Our findings suggest that cognitive deficits in old age may be partly a consequence of PTSD or at least be aggravated by it. However, several study limitations need to considered. Consideration of cognitive deficits when treating PTSD patients and victims of lifespan trauma (even without a diagnosis of a psychiatric condition) is crucial. Furthermore, early intervention may prevent long-term deficits in memory function and development of dementia in adulthood.

In the aftermath of medical error : Caring for patients, family, and the healthcare workers involved

Medical errors, in particular those resulting in harm, pose a serious situation for patients ("first victims") and the healthcare workers involved ("second victims") and can have long-lasting and distressing consequences. To prevent a second traumatization, appropriate and empathic interaction with all persons involved is essential besides error analysis. Patients share a nearly universal, broad preference for a complete disclosure of incidents, regardless of age, gender, or education. This includes the personal, timely and unambiguous disclosure of the adverse event, information relating to the event, its causes and consequences, and an apology and sincere expression of regret. While the majority of healthcare professionals generally support and honest and open disclosure of adverse events, they also face various barriers which impede the disclosure (e.g., fear of legal consequences). Despite its essential importance, disclosure of adverse events in practice occurs in ways that are rarely acceptable to patients and their families. The staff involved often experiences acute distress and an intense emotional response to the event, which may become chronic and increase the risk of depression, burnout and post-traumatic stress disorders. Communication with peers is vital for people to be able to cope constructively and protectively with harmful errors. Survey studies among healthcare workers show, however, that they often do not receive sufficient individual and institutional support. Healthcare organizations should prepare for medical errors and harmful events and implement a communication plan and a support system that covers the requirements and different needs of patients and the staff involved.

Classic and Complex PTSD in Switzerland: Prevalence and Theoretical Discussion

Switzerland seems to present a different picture with reference to PTSD prevalence rates. Probably partly as a result of being largely spared by large-scale catastrophes, compared to other countries, there are rather low PTSD prevalence rates. However, in traumatized or clinical samples, these rates amount to comparable sizes as in other countries. Generally, the empirical landscape concerning PTSD in Switzerland is rather limited. More research is needed to further clarify unsolved questions indicated within this article.

Methylation of NR3C1 is related to maternal PTSD, parenting stress and maternal medial prefrontal cortical activity in response to child separation among mothers with histories of violence exposure.

Prior research has shown that mothers with Interpersonal violence-related posttraumatic stress disorder (IPV-PTSD) report greater difficulty in parenting their toddlers. Relative to their frequent early exposure to violence and maltreatment, these mothers display dysregulation of their hypothalamic pituitary adrenal axis (HPA-axis), characterized by hypocortisolism. Considering methylation of the promoter region of the glucocorticoid receptor gene NR3C1 as a marker for HPA-axis functioning, with less methylation likely being associated with less circulating cortisol, the present study tested the hypothesis that the degree of methylation of this gene would be negatively correlated with maternal IPV-PTSD severity and parenting stress, and positively correlated with medial prefrontal cortical (mPFC) activity in response to video-stimuli of stressful versus non-stressful mother-child interactions. Following a mental health assessment, 45 mothers and their children (ages 12-42 months) participated in a behavioral protocol involving free-play and laboratory stressors such as mother-child separation. Maternal DNA was extracted from saliva. Interactive behavior was rated on the CARE-Index. During subsequent fMRI scanning, mothers were shown films of free-play and separation drawn from this protocol. Maternal PTSD severity and parenting stress were negatively correlated with the mean percentage of methylation of NR3C1. Maternal mPFC activity in response to video-stimuli of mother-child separation versus play correlated positively to NR3C1 methylation, and negatively to maternal IPV-PTSD and parenting stress. Among interactive behavior variables, child cooperativeness in play was positively correlated with NR3C1 methylation. Thus, the present study is the first published report to our knowledge, suggesting convergence of behavioral, epigenetic, and neuroimaging data that form a psychobiological signature of parenting-risk in the context of early life stress and PTSD.

Violence-related PTSD and neural activation when seeing emotionally charged male-female interactions.

Post-traumatic stress disorder (PTSD) is a disorder that involves impaired regulation of the fear response to traumatic reminders. This study tested how women with male-perpetrated interpersonal violence-related PTSD (IPV-PTSD) differed in their brain activation from healthy controls (HC) when exposed to scenes of male-female interaction of differing emotional content. Sixteen women with symptoms of IPV-PTSD and 19 HC participated in this study. During magnetic resonance imaging, participants watched a stimulus protocol of 23 different 20 s silent epochs of male-female interactions taken from feature films, which were neutral, menacing or prosocial. IPV-PTSD participants compared with HC showed (i) greater dorsomedial prefrontal cortex (dmPFC) and dorsolateral prefrontal cortex (dlPFC) activation in response to menacing vs prosocial scenes and (ii) greater anterior cingulate cortex (ACC), right hippocampus activation and lower ventromedial prefrontal cortex (vmPFC) activty in response to emotional vs neutral scenes. The fact that IPV-PTSD participants compared with HC showed lower activity of the ventral ACC during emotionally charged scenes regardless of the valence of the scenes suggests that impaired social perception among IPV-PTSD patients transcends menacing contexts and generalizes to a wider variety of emotionally charged male-female interactions.

Adult Asylum Seekers from the Middle East Including Syria in Central Europe: What Are Their Health Care Problems?

Background Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria. Methods Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an “asylum seeker” or “refugee” from the Middle East. Results In total, 880 patients were included in the study. Of these, 625 (71.0%) were male and 255 (29.0%) female. The median age was 34 (range 16–84). 222 (25.2%) of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%), followed by medical (321, 36.5%) and psychiatric (137, 15.6%). In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%). Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%), followed by neurological problems (n = 70, 21.8%) and gastrointestinal problems (n = 47, 14.6%). There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%), followed by chronic musculoskeletal problems (n = 108, 12.3%) and chronic headaches (n = 78, 8.9%). Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (p<0.0001, and p = 0.05, respectively). Conclusion Overall a remarkable number of our very young group of patients suffered from psychiatric disorders and unspecified somatic symptoms. Asylum seekers should be carefully evaluated when presenting to a medical facility and physicians should be aware of the high incidence of unspecified somatic symptoms in this patient population.In general, there is no major difference between asylum seekers from Syria when compared to other nationalities of asylum seekers from the Middle East.

Traumatic free wall and ventricular septal rupture - 'hybrid' management in a child

A 8-year-old boy showed a traumatic ventricular septal rupture following a blunt chest trauma, and was scheduled for elective catheter closure. Two weeks later, a follow-up echocardiogram revealed a pseudoaneurysm of the anterior wall of the left ventricle. Because of the apical location of the VSD, it was decided to proceed with transcatheter occlusion. After successful VSD closure, the patient was taken to the operation room for surgical repair of the left ventricular pseudoaneurysm. Symptoms and signs seen in patients with ventricular pseudoaneurysms appear to be discrete and variable, and a high clinical index of suspicion with a very close echocardiographic follow-up is strongly recommended after occurrence of a blunt cardiac trauma. The combined 'hybrid' approach of transcatheter closure of the intraventricular rupture followed by surgical closure of the pseudoaneurysm allows for a less invasive and efficient management of this rare combination of post-traumatic ventricular free wall and septal rupture in a child.

Traumatization and chronic pain: a further model of interaction.

Up to 80% of patients with severe posttraumatic stress disorder are suffering from "unexplained" chronic pain. Theories about the links between traumatization and chronic pain have become the subject of increased interest over the last several years. We will give a short summary about the existing interaction models that emphasize particularly psychological and behavioral aspects of this interaction. After a synopsis of the most important psychoneurobiological mechanisms of pain in the context of traumatization, we introduce the hypermnesia-hyperarousal model, which focuses on two psychoneurobiological aspects of the physiology of learning. This hypothesis provides an answer to the hitherto open question about the origin of pain persistence and pain sensitization following a traumatic event and also provides a straightforward explanatory model for educational purposes.

Increased sleep need and daytime sleepiness 6 months after traumatic brain injury: a prospective controlled clinical trial.

Post-traumatic sleep-wake disturbances are common after acute traumatic brain injury. Increased sleep need per 24 h and excessive daytime sleepiness are among the most prevalent post-traumatic sleep disorders and impair quality of life of trauma patients. Nevertheless, the relation between traumatic brain injury and sleep outcome, but also the link between post-traumatic sleep problems and clinical measures in the acute phase after traumatic brain injury has so far not been addressed in a controlled and prospective approach. We therefore performed a prospective controlled clinical study to examine (i) sleep-wake outcome after traumatic brain injury; and (ii) to screen for clinical and laboratory predictors of poor sleep-wake outcome after acute traumatic brain injury. Forty-two of 60 included patients with first-ever traumatic brain injury were available for follow-up examinations. Six months after trauma, the average sleep need per 24 h as assessed by actigraphy was markedly increased in patients as compared to controls (8.3 ± 1.1 h versus 7.1 ± 0.8 h, P < 0.0001). Objective daytime sleepiness was found in 57% of trauma patients and 19% of healthy subjects, and the average sleep latency in patients was reduced to 8.7 ± 4.6 min (12.1 ± 4.7 min in controls, P = 0.0009). Patients, but not controls, markedly underestimated both excessive sleep need and excessive daytime sleepiness when assessed only by subjective means, emphasizing the unreliability of self-assessment of increased sleep propensity in traumatic brain injury patients. At polysomnography, slow wave sleep after traumatic brain injury was more consolidated. The most important risk factor for developing increased sleep need after traumatic brain injury was the presence of an intracranial haemorrhage. In conclusion, we provide controlled and objective evidence for a direct relation between sleep-wake disturbances and traumatic brain injury, and for clinically significant underestimation of post-traumatic sleep-wake disturbances by trauma patients.

Posttraumatic anger in crime victims: Directed at the perpetrator and at the self

This study investigated the targets of anger that are most strongly involved in posttraumatic anger. Using a sample of 218 crime victims, the authors assessed the levels of anger at potential targets (perpetrator, criminal justice system, third persons, and the self ) and their association with severity of posttraumatic stress disorder (PTSD) symptoms. The results revealed that anger was most strongly directed at the perpetrator and at the self, and that anger at other targets was low. Moreover, anger at the perpetrator and at the self showed strong associations with PTSD symptoms, whereas the associations of anger at other targets with PTSD symptoms were low.

Permanent teeth with horizontal root fractures after dental trauma. A retrospective study

The purpose of the present retrospective study was to evaluate the post-traumatic healing of the pulp and periodontium of 32 permanent teeth with horizontal root fractures. Twenty-nine patients, 8-48 years old, who presented at our department with a root fracture between January 2001 and April 2007, participated in the study. Root-fractured teeth with a loosened or dislocated coronal fragment were repositioned and splinted for 14-49 days (average: 34 days). In cases of severe dislocation of the coronal fragment, prophylactic endodontic treatment was performed. Follow-up examinations were conducted routinely after 1,2,3,6, and 12 months. For this study, follow-up took place for up to 7 years post trauma. Of 32 root-fractured teeth, 29 (91%) survived. 10 teeth (31%) exhibited pulpal healing; 13 teeth (41%) were prophylactically endodontically treated within 2 weeks of injury. At the fracture line, interposition of calcified tissue was evident in 6 teeth (19%), and interposition of granulation tissue was observed in 8 teeth (25%). The prognosis of the root-fractured teeth was good, and one-third of the teeth with root fractures possessed a vital pulp at the final examination.

Long-term results after muscle-rib flap transfer for reconstruction of composite limb defects

The authors present the long-term results in a series of 44 cases with post-traumatic bone defects solved with muscle-rib flaps, between March 1997 and December 2007. In these cases, we performed 21 serratus anterior-rib flaps (SA-R), 10 latissimus dorsi-rib flaps (LD-R), and 13 LD-SA-R. The flaps were used in upper limb in 18 cases and in lower limb in 26 cases. With an overall immediate success rate of 95.4% (42 of 44 cases) and a primary bone union rate of 97.7% (43 of 44 cases), and despite the few partisans of this method, we consider that this procedure still remains very usefully for small and medium bone defects accompanied by large soft tissue defects.

Proximal row carpectomy in emergency

Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of early post-traumatic degenerative disease of the wrist. Much less frequently, PRC has been advocated as an emergency procedure for irreparable fracture-dislocation of the wrist. Our objective was to compare the results of PRC in patients having undergone this procedure in the two contexts. We conducted a retrospective analysis of the clinical and radiographic results of six patients treated by emergency PRC as compared to six patients who underwent elective PRC. The mean follow-up was 36 months. Both the patient's satisfaction and the grasp of the wrist joint were significantly better in patients who underwent PRC emergency as compared to those having undergone elective PRC. Quick DASH score, radiographic results, and return to work were also more favourable in these patients, but the difference between the two groups was not significant. This study confirms that PRC is a valuable salvage technique indicated in early posttraumatic wrist collapse. Moreover, when performed in emergency, the procedure shows even better subjective and objective results, allowing a majority of patients to return to their previous job.
