  • CONCLUSIONS: Our study did not demonstrate a correlation between PVI and clinical course for asthmatics. PVI may be more clinically relevant in sicker children. Furthermore, it is possible that continuous monitoring of PVI may demonstrate more unique trends in relation to asthma severity versus single values of PVI. Additional studies are necessary to help clarify the relationship between PVI and the clinical course of children with SA.

  • CONCLUSIONS: Legendary physician Sir William Osler truly said that "Medicine is learned by the bedside and not in the classroom." Bedside history taking and physical examination should be an integral component of clinical teaching curriculum imparted to medical students. Pulsus paradoxus is a valuable physical sign seen in many clinical conditions. Pulsus paradoxus is defined by an inspiratory fall in systolic blood pressure of greater than 10 mm Hg. Two prototype examples of pulsus paradoxus are cardiac tamponade and acute asthma. Exaggerated swings of intrapleural pressure, bi-ventricular interactions and increase afterload of the left ventricle are few of the pathophysiological mechanisms involved in the causation of pulsus paradoxus. The sensitivity of pulsus paradoxus in the diagnosis of cardiac tamponade is very high. In acute asthma, it also correlates with the severity of airflow obstruction.

  • Pericarditis. [Journal Article]

  • CONCLUSIONS: Characteristic clinical findings in pericarditis include pleuritic chest pain and pericardial friction rub on auscultation of the left lower sternal border. Electrocardiography may reveal diffuse PR-segment depressions and diffuse ST-segment elevations with upward concavity. The most common aetiologies of pericarditis are idiopathic and viral, and the most common treatment for these are nonsteroidal anti-inflammatory drugs and colchicine. The complications of pericarditis include pericardial effusion, tamponade and myopericarditis. The presence of effusion, constriction or tamponade can be confirmed on echocardiography. Tamponade is potentially life-threatening and is diagnosed by the clinical findings of decreased blood pressure, elevated jugular venous pressure, muffled heart sounds on auscultation and pulsus paradoxus.
