11/91. Coronary microvascular abnormality in the reversible systolic dysfunction observed after noncardiac disease.Acute reversible left ventricular wall motion abnormalities mimicking myocardial stunning have been reported with noncardiac disease and their coronary angiograms did not demonstrate organic stenosis or vasospasm in the epicardial coronary arteries. Thus, this mechanism has not yet been fully clarified. Two patients are reported as demonstrating acute reversible wall motion abnormalities after noncardiac disease. The electrocardiographic and echocardiographic findings mimicked myocardial stunning and confirmed the previous reports. The coronary angiograms did not show any corresponding coronary stenosis or vasospasm, but did show a reduced coronary flow reserve. Cardiac metaiodobenzylguanidine scintigraphy demonstrated regional defects involving the apex, a decreased heart/mediastinum ratio and an enhanced washout rate, which partially returned to normal after 3 months. Microvascular dysfunction and sympathetic nervous abnormalities might be responsible for the reversible contractile impairment.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
12/91. Paradoxical vocal cord adduction mimicking as acute asthma in a pediatric patient.We report an adolescent girl with paradoxical vocal cord adduction who presented with acute onset of hyperventilation, wheezing and stridor that did not respond to bronchodilator and anti-inflammation therapy. The paradoxical vocal cord motion was confirmed by flexible fiberoptic bronchoscopic examination. We found the stridor was induced by hyperventilation, and was caused by paradoxical vocal cord movement. The abnormal cord motion may be psychogenic and could be misdiagnosed as asthma. It is important to investigate the underlying background and social history and to avoid unnecessary use of beta-agonists, steroids, and even endotracheal intubation or tracheostomy.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
13/91. Acute transient monocular disequilibrium (Halpern's syndrome).An acute transient form of monocular disequilibrium (Halpern's syndrome) was found in two patients. Misjudgement of verticality and motion was induced by looking with one eye and was alleviated by use of the fellow eye. This symptomatology is discussed in the light of recent concepts of oculovestibulocerebellar integration.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
14/91. Echocardiographic findings of ventricular septal rupture in acute myocardial infarction.Echocardiograms were recorded both before and after the clinical appearance of an autopsy-confirmed interventricular septal rupture in a patient with an acute myocardial infarction. The major findings were related to the upper portion of the interventricular septum. Before rupture, this portion of the septum was relatively akinetic with a slight anterior motion during systole, whereas after rupture there was a marked increase in the amplitude of septal motion with abrupt posterior motion occurring with the onset of ventricular diastole.- - - - - - - - - - ranking = 1.5keywords = motion (Clic here for more details about this article) |
15/91. Acute ST-segment elevation in Neisseria meningitis.meningitis due to neisseria meningitidis occurred in a young man. On admission, he was in septic shock and the electrocardiogram revealed convex upwards ST-segment elevation in inferior and lateral leads. Rapid and complete normalisation of the ECG was observed and the patient had a favourable evolution with intensive therapy.The mechanisms of the ECG abnormalities in this disease are unclear. In this patient, ST-segment elevation was probably related to severe transmural ischaemia or prolonged coronary artery spasm as suggested by increase and decrease of cardiac enzymes and transient echocardiographic wall motion abnormalities without pericarditis. However, myocarditis could not be completely ruled out.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
16/91. Ultrasonic tissue characterization in acute myocarditis: a case report.A 25-year-old woman was admitted because of acute myocarditis. Echocardiogram revealed hypokinesis of the left ventricle with increased wall thickness, but on day 7, the wall motion normalized. Cyclic variation of myocardial integrated backscatter on day I was reduced to 1.8 dB (normal range, 2.9-5.3 dB) and normalized to 3.2 dB on day 3. The normalization of the cyclic variation of integrated backscatter in the myocardium preceded the recovery of the left ventricular wall contractility, suggesting the ability of tissue characterization to predict recovery of cardiac function.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
17/91. magnetic resonance imaging in acute myocarditis: a case report and a review of literature.We report a case of acute myocarditis in a 20-year-old male, suggested by the clinical picture, elevated cardiac enzymes, electrocardiography and serology. diagnosis was confirmed by gadolinium-enhanced MRI showing part of the myocardium affected by an infiltrate. Impaired LV function and wall motion abnormalities were documented by echocardiography and FFE MRI. The patient recovered well within two weeks, but will be followed intensively since dilated cardiomyopathy may ensue.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
18/91. anger and acute coronary events.A high level of anger has a powerful effect on the incidence of preventable cardiovascular death. Persuasive clinical evidence indicates that anger evokes physiological responses that are potentially life-threatening in the setting of CAD. Finally, emotional stress, anger, or worry have a dominant influence on the severity, frequency, and treatment of angina. The natural history of angina is characterized by episodic variations in the frequency and severity of symptoms coincident with periods of emotional stress. When angina is associated with periods of emotional stress or anger, the angina is not usually a result of progressive coronary disease, but rather is due to an increase in oxygen demand. Appreciation of this concept will help to rule out "true" unstable angina due to progressive coronary disease from recurrent angina that results from an increase in oxygen demand related to emotional stress. The former requires aggressive medical or surgical therapy; the latter, a demand-induced angina, responds to beta-adrenergic blockade and a tranquilizer.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
19/91. Delayed and severe but transient tourette syndrome after head injury.A previously well and intellectually normal 7(1/2)-year-old girl developed an acute and severe tourette syndrome 15 months after sustaining a severe head injury. The patient displayed a dramatic response to haloperidol. Twelve months after the onset of tourette syndrome the haloperidol was withdrawn, and there was no relapse of either her motor or phonic tics. Seven years after the head injury the patient remains tic free but demonstrates significant emotional and behavioral sequelae. The patient's brain magnetic resonance imaging findings were consistent with those reported previously in adults with tourette syndrome.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
20/91. Early identification and management of critical incident stress.Everyone experiences stress. That stress may be related to work (internal), community (external), or family; it may be cumulative or related to a particular critical incident. The cost related to treating acute stress is staggering, both to individuals and to organizations. critical care nurses are well educated in the physiological responses to the stress of acute illness. Recognizing the emotional impact of stress and the techniques to manage it in themselves and in those with whom they work is equally as important. CISD is widely advocated as an intervention after critical incidents. Although debriefing in and of itself is effective, a single-session semistructured crisis intervention will not prevent posttraumatic stress; thus, the use of CISD as part of a comprehensive multifaceted approach to the management of acute stress related to a critical incident is recommended.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
