Emboli rate during and early after carotid endarterectomy after a single preoperative dose of 120 mg acetylsalicylic acid--a prospective double-blind placebo controlled randomised trial.

PURPOSE: To investigate whether a single pre-operative dose of 120 mg acetylsalicylic acid (ASA) decreased either (1) emboli rate, as detected by transcranial Doppler (TCD), during and early after carotid endarterectomy (CEA) and (2) clinical intra- and post-operative signs suggestive of embolism or increased bleeding tendency. DESIGN: Prospective, double-blind placebo controlled trial. PATIENTS AND METHODS: One-hundred consecutive patients were randomised to receive either 120 mg ASA (n = 48) or placebo (n = 49) by suppository on the night before CEA; three patients were excluded. Emboli were counted and expressed as emboli rate (ER). The incidence of bleeding complications was assessed. Surgeons were asked to indicate which patients had received ASA or placebo. RESULTS: There were no significant differences between the ASA and placebo groups in ER in the intraoperative and postoperative periods. ER higher than 0.9 min(-1) was associated with a significantly increased risk of complications (26 vs. 0%, P < 0.01). No extra bleeding complications were observed in the ASA group. Surgeon assessment of whether or not ASA had been administered had a sensitivity of 42% and a specificity of 70%. CONCLUSION: A single pre-operative dose of ASA (120 mg) did not reduce significantly the emboli rate during and after CEA and surgeons could not correctly identify whether or not ASA had been administered.

Prevalence and course of posttraumatic stress disorder in Dutch veterans of the civilian resistance during World War II: an overview.

This study concerns the prevalence of current and lifetime Posttraumatic Stress Disorder (PTSD) in various groups of officially recognized Veterans of the Dutch civilian Resistance against the Nazi occupation during World War II. In total, 1046 Resistance veterans living in The Netherlands and 52 who immigrated to the United States after the war were examined. Between four and five decades after the end of WW II, between 25 and 50% were suffering from current PTSD. The life-time prevalence is estimated to be substantially higher. The course of PTSD proved highly variable. There had often been a delay of several decades between the end of the war and reoccurrence or first onset of posttraumatic symptoms. The prevalence of PTSD in Resistance veterans who emigrated to the United States was hardly different from that of the veterans still living in The Netherlands.

Posttraumatic stress disorder in male and female Dutch Resistance veterans of World War II in relation to trait anxiety and depression.

In this study, 680 male and 144 female Dutch Resistance veterans of World War II were evaluated on Posttraumatic Stress Disorder, trait anxiety, and depression. Approximately 27% of these men and 20% of these women showed current Posttraumatic Stress Disorder. Resistance veterans, as a group, appeared comparable to the controls from Dutch validation studies on trait anxiety and depression. Gender differences were not observed. Veterans with current PTSD symptoms scored higher on trait anxiety and depression than the remaining veterans and were comparable on trait anxiety and depression to psychiatric patients. Correlational analyses showed that there was a strong association between trait anxiety and depression. Posttraumatic Stress Disorder correlated highly with trait anxiety and depression.

Fluvoxamine treatment for chronic PTSD: a pilot study.

A group of 24 Dutch World War II Resistance veterans with a documented traumatic war history and a (partially) positive diagnosis of current posttraumatic stress disorder (PTSD) was studied. This special group of war victims is characterised by chronicity, suffering from intractable posttraumatic complaints for decades. They were treated with fluvoxamine (Fevarin), a selective serotonin reuptake inhibitor with antidepressive and anxiolytic properties. The study was designed as an open-ended, outpatient pilot study, with a treatment period of 12 weeks. Results of clinical examination, and questionnaires investigating PTSD, depression, sleeping problems, anxiety, and vital exhaustion indicate that a significant number of the subjects improved with respect to their PTSD symptomatology, and their symptoms of anxiety and vital exhaustion. However, at the end of the study, quantitative improvement was modest. The results indicate that treatment with fluvoxamine may offer alleviation of chronic PTSD symptoms, in particular insomnia, nightmares, anxiety, intrusive recollections, guilt feelings and tiredness.

Current posttraumatic stress disorder and cardiovascular disease risk factors in Dutch Resistance veterans from World War II.

The extraordinary trauma experienced by Resistance veterans from World War II (WW II) and other veterans may be associated with an increased incidence of posttraumatic stress disorder (PTSD) and somatic morbidity, including cardiovascular disease (CVD). This study explored some relationships between current PTSD and CVD risk factors in 147 male Dutch WW II Resistance veterans. They were compared to 65 same-aged male patients with a recent myocardial infarction and 79 surgical patients. Of these subjects, WW II Resistance veterans scored highest on CVD risk factors (i.e., angina pectoris, type A behavior, life stressors, and vital exhaustion), except smoking. Fifty-six percent of these veterans were currently suffering from PTSD. They reported CVD risk factors, in particular type A behavior and vital exhaustion, more often than veterans without PTSD; they also reported more premorbid adverse living conditions. These data suggest that early sensitization to environmental stressors may be associated with a high prevalence of current PTSD and excess CVD risk factors in subjects exposed to extraordinary war-time trauma and that this may lead to vital exhaustion.

Anxiety, depression and anger in Dutch Resistance veterans from World War II.

In this study, 147 Dutch Resistance veterans from WW II are evaluated on psychometric instruments for anxiety, depression and anger. Resistance veterans appeared to be more anxious, depressive and angry on these instruments compared to controls from the validation studies of the respective instruments. Veterans currently suffering from PTSD (56%) were significantly more anxious, depressed, and angry than veterans without PTSD. With respect to staying in Nazi concentration camps, which is an extremely severe stressor, and in which half of the veterans were imprisoned, no difference on the three instruments was found. Anxiety, depression and anger were observed to be highly interrelated in PTSD. The close interrelationship between anxiety and depression, anxiety and danger, and depression and anger mediated by way of anxiety is, however, not unique for traumatized subjects. It is argued that for Resistance veterans only the intrusive reminiscences of the stressful events discriminate this constellation of symptoms from subjects with an anxious-depressive symptomatology.

A neuromuscular transmission disorder: combined myasthenia gravis and Lambert Eaton syndrome in one patient.

The distinction between myasthenia gravis and Lambert Eaton myasthenic syndrome can usually be made by the clinical and neurophysiological features. A patient was observed with features which suggested a combination of both disorders. This has been described in few patients before. The importance of electromyography in both distal and proximal limb muscles for a correct diagnosis is demonstrated. Only in proximal nerve stimulation tests was proof found of the existence of both syndromes.
