Hintergrund: Erhöhte Schmerzempfindlichkeit ist ein charakteristisches Merkmal von Patienten mit chronischen Schmerzstörungen mit somatischen und psychischen Faktoren (F45.41). Anhaltendes Stresserleben kann erhöhte Schmerzempfindlichkeit auslösen, aufrechterhalten oder verstärken und dadurch Schmerzerleben modulieren. In diesem Zusammenhang interessiert, welche psychosozialen Stressoren mit der Schmerzempfindlichkeit verbunden sind. Ziel der Arbeit: Ziel der Arbeit war die Untersuchung von Zusammenhängen zwischen psychosozialen Stressoren und Schmerzempfindlichkeit innerhalb einer naturalistischen Stichprobe von Patienten mit chronischen Schmerzstörungen mit somatischen und psychischen Faktoren (F45.41). Material und Methoden: 166 Patienten mit einer chronischen Schmerzstörung gemäß F45.41 wurden im Rahmen einer stationären Schmerztherapie untersucht. Die Schmerzempfindlichkeit wurde mit dem Schmerzprovokationstest Algopeg an Mittelfinger und Ohrläppchen gemessen. Die Stressoren Kriegserfahrung, belastende Kindheitserfahrungen, krankheitsbedingte Arbeitsunfähigkeit, Partnerschaftsprobleme und potenziell lebensbedrohlicher Unfall wurden erfasst. Nach der Berechnung von Korrelationsanalysen wurde mit einem Strukturgleichungsmodell geprüft, welche Stressoren die Schmerzempfindlichkeit am besten vorhersagen. Ergebnisse: Die untersuchte Patientengruppe wies eine erhöhte Schmerzempfindlichkeit auf. Kriegserfahrungen und krankheitsbedingte Arbeitsunfähigkeit korrelierten innerhalb dieses Kollektivs statistisch signifikant mit erhöhter Schmerzempfindlichkeit. Dieselben Stressoren sagten neben dem Alter im Strukturgleichungsmodell weiter erhöhte Schmerzempfindlichkeit vorher. Diskussion: Unter Berücksichtigung der Einschränkungen dieser Querschnittsuntersuchung können die Ergebnisse zu einem besseren Verständnis der Zusammenhänge zwischen psychosozialen Stressoren und der Schmerzempfindlichkeit beitragen., BACKGROUND: Increased pain sensitivity is characteristic for patients with chronic pain disorder with somatic and psychological factors (F45.41). Persistent stress can induce, sustain, and intensify pain sensitivity, thereby modulating pain perception. In this context, it would be favorable to investigate which psychosocial stressors are empirically linked to pain sensitivity. OBJECTIVES: The aim of this study was to examine the relationship between psychosocial stressors and pain sensitivity in a naturalistic sample of patients with chronic pain disorder with somatic and psychological factors (F45.41). MATERIALS AND METHODS: We assessed 166 patients with chronic pain disorder with somatic and psychological factors (F45.41) at entry into an inpatient pain clinic. Pain sensitivity was measured with a pain provocation test (Algopeg) at the middle finger and earlobe. Stressors assessed were exposure to war experiences, adverse childhood experiences, illness-related inability to work, relationship problems, and potentially life-threatening accidents. Correlation analyses and structural equation modeling were used to examine which stressors showed the strongest prediction of pain sensitivity. RESULTS: Patients exhibited generally heightened pain sensitivity. Both exposure to war and illness-related inability to work showed significant bivariate correlations with pain sensitivity. In addition to age, they also predicted a further increase in pain sensitivity in the structural equation model. CONCLUSIONS: Bearing in mind the limitations of this cross-sectional study, these findings may contribute to a better understanding of the link between psychosocial stressors and pain sensitivity.

The manuscript Berlin, SBB-PK, mgf 863 was written in about 1430 to 1435 and contains more than 600 short narrative texts in German prose (with some Latin insertions). Among them is the collection of the ›Alemannische Vitaspatrum‹ as well as an additional, extensive and multifarious exempla corpus, which mostly contains translations from well-known Latin collections such as – for example and most prominently – Caesarius' of Heisterbach ›Dialogus miraculorum‹. Because of the specific composition of the corpus and its large extent, mgf 863 builds an excellent basis for the investigation of exempla, a text type which has not received much attention in German studies.The manuscript was probably produced in Strasbourg where it belonged to the library of the nuns from the convent of St Mary Magdalen. It contains a large quantity of textual material with close links to Strasbourg in terms of content or history of transmission. My primary interest is in the texts in the manuscript, in their contents and interdependencies, as well as in their history and their contextualization in, for example, groups of manuscripts, exempla tradition and religious practice. The project aims at a contribution to exempla research as well as to literary and religious life in Strasbourg in the late Middle Ages.My approach comes primarily from literary studies, but also uses palaeographical, textualcritical, and historical methods. The thesis combines case studies of the transmission of individual exempla or groups of exempla with general research into the history of texts (›Textgeschichte‹) and the history of transmission (›Überlieferungsgeschichte‹) of German prose exempla. A repertory in the appendix provides an overview of the manuscript's content. It helps to orientate within the study; furthermore, with over 600 entries, it provides a tool for the identification of German exempla.

- Abstract
Ultrasound is an easy to learn and highly efficient diagnostic tool to complete the clinical examination and improve bedside decision-making. In the trauma room, surgeons are often required to make a quick decision as to whether or not a patient needs an emergency intervention or whether further diagnostics are required. For this reason, education of surgeons in performing focused emergency ultrasound is pivotal. The goal of ICAN is to improve and expand the education of surgeons in Switzerland. This article provides a short review of the most frequent surgical pathologies encountered in the emergency room.

- Abstract
Conventional open surgery for abdominal aortic aneurysm has recently been challenged by a closed transfemoral approach for repair (stent-graft). The presented data over the past eleven years after open surgery for graft implantation are intended to serve for comparison with future results after transfemoral graft placement. In addition, it is the purpose of this study to investigate the prognostic importance of treatment of concomitant coronary artery disease. Early mortality of all 195 consecutive patients with abdominal aortic aneurysm repair was 1.5%; it was 0.6% after elective repair for infrarenal aneurysm and not dependent on the presence of coronary artery disease if the latter was treated. Late outcome, however, related closely to coronary artery disease as a major risk factor. Late graft complications are extremely rare and occurred only once (graft thrombosis). Incisional hernias and impotence in male patients are non-lethal complications affecting quality of life. Open surgical repair of abdominal aneurysm is safe, and long-term, complication-free survival is good. Coronary artery disease is the most frequent concomitant disease and major risk factor requiring close observation and treatment. These results need to be matched by the new transfemoral graft implantation technique before broad application of the latter.

- Abstract
From 1987 to 1996 we operated on 263 patients for mitral insufficiency. Multiple valve operations were excluded, with the exception of tricuspid reconstruction for functional regurgitation. The perioperative mortality was 3%, while the late mortality rate during a mean follow-up period of 3.5 years amounted to 2% per patient year and 1.7% if only cardiac causes were considered. The prognosis for patients with rheumatic, endocarditic and ischemic valvular disease was much worse compared to that for a degenerative cause. The latter group consisted of 209 patients with an operative mortality of 1.4% and a late mortality rate per patient year of 1.4% and 0.9% for cardiac causes only. Further analysis showed a significant prognostic improvement for patients with a preoperative ejection fraction of more than 60% and a repairable valve.

- Abstract
The aim of the study was to identify causes for perioperative stroke in cardiac surgery in order to reduce its occurrence. From 1989 to 1994, 3593 open heart operations were performed in adult patients. In 59 patients carotid endarterectomy for high grade stenosis was combined with the cardiac operation. There were a total of 68 (2%) focal strokes, 41 of which were considered minor and 14 major; 13 were lethal. The etiology of the 27 major and lethal events was most probably an embolus from the ascending aorta (6), from the ascending aorta or a cardiac valve (5), a thrombus in the left heart (6), air (1), cardiac arrest and resuscitation (4), cerebral hemorrhage (1), preoperatively unknown but high grade internal carotid stenosis (3), and a 50% stenosis of both internal carotid arteries preoperatively known but not operated on (1). There were 2 minor but no major neurologic complications in patients undergoing a combined carotid and cardiac procedure. A wide indication for preoperative neuroangiologic examination, echocardiography and careful intraoperative management may help to identify sources of possible emboli. Endarterectomy of high grade carotid stenosis is recommended simultaneously with the cardiac procedure.

- Abstract
Unlabelled: To obtain information on the outcome of medullary thyroid carcinoma (MTC) in the Berne area, a retrospective analysis of the 28 MTCs diagnosed by the Institute of Pathology of the University of Berne in the 25-year period between 1969 and 1994 was done. These 28 MTCs represented 2.4% of all thyroid malignancies diagnosed at the Bernese Institute of Pathology in the 25-year period mentioned above. 25 MTCs were sporadic and 3 associated with a multiple endocrine neoplasia (MEN) syndrome. Follow-up data were available from 27 of the 28 MTC patients. After a follow-up period of between 2 and 275 months 7 of these 27 patients had died form the MTC (among them all 4 patients with T4 tumors) and two were alive with tumor. 18 patients, including all 14 patients with T1 or T2 tumors without lymph node or distant metastases at the time of diagnosis, were alive and without evidence of tumor at the end of the follow-up period., Conclusions: MTCs are rare malignant tumors and comprise only a small fraction of all thyroid carcinomas in the Berne area. Most MTCs were sporadic, only a small minority was associated with a MEN syndrome. The TNM stage was the most important prognostic factor for patient survival. These data are in accordance with the results of similar MTC surveys done in other areas.

- Abstract
Understanding of the mechanisms of cardiovascular and hemodynamic adaptation during pregnancy helps to prevent or manage complications in cardiac patients during gestation. Manifestations of coronary heart disease are exceptional during pregnancy and delivery. The same is true of disorders of the pericardium. Peripartal cardiomyopathy is a myocardial disorder of undetermined cause occurring shortly before, during or after delivery, which may take a fatal course. Hypertrophic obstructive or non-obstructive cardiomyopathy is compatible with gestation and delivery without serious complications in most cases. Rheumatic mitral stenosis was the most common cardiac disorder until the 1950s. Nowadays it is rarely seen in this country. Surgical and other interventional therapies have greatly changed the outlook in pregnant women with valvular heart disease. A highly controversial issue is heart valve replacement in young women and management of anticoagulation during pregnancy. Like any other drug therapy, anticoagulation during gestation requires careful weighing of the benefit for the mother against toxic and teratogenic effects for the fetus. In women with heart disease the management of pregnancy should start, if possible, before conception. Thorough counseling and proper planning of pregnancy and of therapeutic measures is essential in order to avoid or manage complications.

- Abstract
This report documents the introduction of standard-setting in the haemato-oncological reverse-isolation unit of the Kanton hospital, Basle. The topic is the prevention or reduction of nausea, choking and vomiting, and the treatment of patients who are receiving prolonged chemotherapy. The objective was quality assurance in nursing care. The definition of the desired outcome was the well-being and safety of patients. In addition the wish of the staff to increase their security in dealing with antiemetics was taken into consideration. The authors describe the basic problems they encountered in their strategies and actions for standard setting. By extensive use of measurement and evaluation it was possible, in cooperation with medical leadership, to develop instructional leaflets and checklists. Approximation to the intended outcome was achieved. The well being of patients and satisfaction of the safety-needs of staff and patients reached a high level. The report shows that the introduction of nursing standards requires great effort and a high level of commitment of the entire team. It also shows that the effort is worthwhile for patients and staff.

- Abstract
Fewer subjects return to work after acute myocardial infarction or a cardiac surgical procedure than one would expect from the results of their medical examinations and cardiac tests. To decide whether a patient is able to return to work, one has to assess his individual prognosis and measure his maximal physical working capacity without cardiac dysfunction. Psychological and socioeconomic aspects have also to be considered. Recommendations are presented for practical procedure in assessing the ability of a patient to return to work.

- Abstract
Electrically powered devices represent a hazard for patients with cardiac pacemakers. The aim of the present investigation was an in vivo evaluation of possible interactions between electrically powered dental instruments and the function of artificial pacemakers in humans. In 26 patients with artificial pacemakers, different dental instruments were applied, including air scaler, ultrasonic curets, electric pulp tester and electrotome. These devices were applied at highest intensity. Immediately prior to, during, and immediately after applications of these instruments, the pulse rate and the electrocardiogram (EKG) were recorded. The EKG recordings were assessed for irregularities in the distances between the pacemaker peaks. The dental devices were assessed for magnetic fields or induction tension. The results showed that none of the dental devices caused an irregularity in the pacemaker function. The air scaler, Piezon ultrasonic curet and the electric pulp tester caused no measurable magnetic fields. The Sonus 2 ultrasonic curet and the electrotome magnetic fields were measured up to 60 and 50 cm, respectively. All dental devices caused induction tension. The highest value was produced by the electrotome. It seems that cardiac pacemaker function is not affected by electrically powered dental devices. However, there remains a risk in relation to older pacemakers or defective dental devices.

- Abstract
Between 1987 and 1990 we operated on 104 patients for mitral valve disease. If possible the valve was reconstructed according to CARPENTIER's technique: 8 of 28 stenotic, 43 of 57 regurgitant and 2 of 7 mixed lesions were repaired. Twelve patients underwent re-replacement of a previously inserted mitral prosthesis. Six patients died early (7.8% after replacement, 8% after isolated replacement, 3.7% after repair and 2% after isolated repair). Five of these six patients were in NYHA class IV preoperatively. Seven patients died late after a mean observation period of 18 months (5 after replacement, 1 after double valve replacement and 1 after repair and multiple coronary bypass surgery). Prognosis is best for patients whose valve can be repaired and who are not already in NYHA class IV. The postoperative NYHA class for surviving patients is excellent (1.3 in the replacement group and 1.2 after repair).

- Abstract
435 isolated coronary artery procedures have been performed between January and December 1989 at the HerzZentrum Hirslanden. In 93% of the cases, one or two internal mammary arteries (IMA) and in 7%, saphenous vein grafts only were used as a bypass conduit. In 12 patients, the right gastroepiploic artery (RGE) was used as a free (3) or pedicled (9) graft to the posterior surface of the heart. This group of 12 patients was analyzed in a retrospective study. Postoperative complications in this group included one myocardial infarction and reexploration for intraabdominal bleeding in the same patient. All patients were discharged from hospital after an average of 9.7 days. After a mean follow-up time of 5 months, all patients are in NYHA-functional class I without antiischemic drugs. Postoperative angiography in 7 patients (mean postoperative interval 4 months) showed all 13 IMA-grafts and 5 RGE-grafts patent, 1 RGE-conduit is occluded, 1 RGE-graft could not been assessed for technical reasons. The RGE is an viable additional arterial bypass conduit and an alternative to other grafts. Indications for use of the RGE are lack of sufficient other conduits, calcified ascending aorta, coronary reoperation after vein graft failure and probably young patients with severe hyperlipidemia.

- Abstract
Incidence, risk and results of emergency coronary bypass surgery after failed percutaneous transluminal coronary angioplasty (PTCA) have been analyzed in a retrospective study. Failed PTCA has been defined as visible pathology (dissection, occlusion) of the dilated vessel associated with acute chest pain and ECG changes. From 3-1-1987 to 11-30-1990, 23 patients of 433 (5%) underwent emergency surgery for failed PTCA (19 male, 4 female, mean age 55 +/- 8 years). PTCA was performed in 16 cases of one-vessel-disease, 3 cases of two-vessel-disease and 4 cases of three-vessel-disease. All had an ejection fraction beyond 40%. 19 patients remained in stable hemodynamic condition. In average 2.1 vessels have been bypassed; in 13 cases the internal mammary artery (IMA) has been used, in 10 cases the saphenous vein (VSM) only. No early nor late death occurred. The perioperative infarction rate is 30%. Comparing the group with IMA and the group with VSM only, no difference could be found regarding the number of unstable hemodynamics, the use of catecholamines nor the perioperative infarction rate. After a mean follow-up period of 14.3 months, 21 patients are in NYHA class I, 2 in NYHA class II. Emergency coronary bypass surgery can be performed with low risk and favorable results, if the operation is timed without delay after the onset of acute chest pain and ECG changes in failed PTCA. The infarction rate is remarkably higher than in elective coronary surgery. The use of the IMA seems to be no additional risk factor.

- Abstract
Based upon the experiences at the "Herzzentrum Hirslanden" Zurich it is demonstrated that heart surgery and invasive cardiology, including cardiac catheterization and PTCA, can readily be performed by surgeons and cardiologists in private practice at a private hospital not receiving any government funds. The needs for additional heart surgical beds in the greater area of Zurich is confirmed. Manpower needed and necessary apparative infrastructure are discussed and present activities at the "Herzzentrum Hirslanden" illustrated. Finally problems with medical insurance companies covering the cost are dealt with.

- Abstract
From 1979 to April 1984, 51 patients were reoperated on for postoperative angina pectoris. Three patients died early and 4 late. The cause of death was cardiac in all cases. After the second operation the mean observation period was 24.2 months and the mean functional class 2.0. These results were somewhat worse than was to be expected after the first operation. The single significant risk factor was an ejection fraction reduced below 50%. The indication for reoperation should therefore be confined to patients with severe angina, good left-ventricular function, bypassable coronary arteries and sufficient graft material available (saphenous vein, internal mammary artery).

- Abstract
Retransfusion of mediastinal shed blood after cardiopulmonary bypass has markedly reduced requirements of homologous blood or blood products. It also decreased the incidence of early reoperation for bleeding. The additional use of a cell saver has not further reduced blood requirements but it improved the patient's perioperative water balance.

- Abstract
Over a period of 15 years, 89 patients (70 male, 19 female) aged 15-76 (mean 48) underwent surgery for acute (64) or chronic (25) dissecting aneurysm type I or II. Early mortality was 18% (16 patients); 8 patients died late (2.8% per year); 8 patients had to be reoperated because of late complications on the aorta. Although very often it is not possible to remove or replace the entire diseased aorta, the goal of the operative procedure is to reduce the risk of rupture by replacing the entry site with a dacron graft. Late reoperation has to be considered if dissection progresses or a new aneurysm develops.

- Abstract
Between 1980 and 1983, 103 patients over the age of seventy (average 72.5 years) underwent cardiac surgery. It comprised 41 aortic valve replacements, 11 mitral valve operations, 7 aortic and mitral valve procedures, 18 valve replacements with concomitant coronary artery bypass grafting, 17 coronary revascularizations, 7 operations for VSD after acute myocardial infarction and 2 procedures for dissecting aneurysm of the ascending aorta. Early mortality was 7.8% and late mortality 10% after a mean follow-up of 29.3 months. Preoperative NYHA-class IV is an incremental risk factor for early and later cardiac death. Early and late results are very satisfactory in patients with isolated valvular lesion, with or without concomitant coronary artery disease, and for isolated coronary atherosclerotic heart disease, whereas there is a high risk of early and late death in patients with multiple valvular lesions or VSD after acute myocardial infarction.
